OPERATION

2.5.1

FAST HEATING

In order for the press to run efficiently, the oil temperature must be kept at around 40°C. If the oil is below this temperature when the machine begins to run, the press heats it up to at least 30°C before starting an automatic work-cycle. However,it is possible to start up the machine.

NOTE: With temperatures lower than 5°C, use an external heater.

At temperatures below 30°C the pumps of the hydraulic power unit will recirculate the oil at a pressure of 150 bar. The pressure is controlled by proportional pressure relief valve YV309. As the oil circulates the electrical energy dissipated is converted into heat. With the help of logic element 111, the dissipated energy heats up all the oil in a short time (depending on the initial temperature). If the controller finds the oil temperature to be <2°C it prevents main motor M1from being started up.2.5.2

ADDITIONAL OIL HEATER (OPTIONAL)

An additional oil heater can be used in order to start up the machine when the oil temperature is below 5 °C.This heater includes motor-screw pump M18 and electric heater EH18.

If the oil temperature is below 5 °C when the press is started up, the PLC will not allow motor-filtering pump M11 to start running while motor M18 starts running. In addition, heater EH18 is energized until thermocouple BT4 measures the oil temperature is equal to or higher than 5°C.

Once this threshold has been exceeded, the system shuts off M18 and EH18 and allows motor-pump M11 and then main motor M1 to start running.

Thermostat T18 is installed at the oil heater outlet. This instrument is set to 60°C to prevent the oil from being damaged shutting down the heater and displaying a fault message in the event of motor-pump M18 or line malfunctioning.2.5.3

HEAT EXCHANGER AND FILTERING SYSTEM

The system consists of screw pump-and-motor unit M11-78, plate-type water-oil heat exchanger 48 and filter 79.Pump 78 draws the oil from the prefilling tank and delivers it to filtering unit 79 and heat exchanger 48. The oil is then sent to the main pumps.

Filters 79 are provided with pressure switches SP1 and SP1S which indicate when the filter elements are clogged.The flow rate of the cooling water is controlled by valve YV279.

The microprocessor based system measures the oil temperature thanks to thermocouple BT4 (located on the hydraulic power unit’s reservoir).

If the temperature increases

YV279 is energised when it reaches 41°C

Drive motor M1 will stop if motor M11 shuts off. As a result, the automatic work-cycle will be interrupted. To bring motor M1 back into operation, first run the heat exchanger motor M11by pressing button 0 on the control console.

If the temperature decreases

YV279 is de-energised when it reaches 39°C

2.5.4

OIL LEAK RECOVERY SYSTEM

Tank 105 collects the hydraulic oil leaks from main cylinder 124 and KNOCKOUT SPE .

A level sensor, known as “1st oil level” (SL3) , is located inside tank 105; when the oil reaches the top level mark, motor-and-pump unit M3-85 will start running. The oil which passes through filter 86 is drawn out by the pump which will, in turn, deliver it to the reservoir of the hydraulic power unit.

Check valve 54 is used to prevent the oil from flowing back to tank 105. The level sensor will shut the pump off when the oil reaches the lower level mark.

A second “oil level sensor” (SL4) is located within tank 105. If the oil cannot be pumped into the reservoir of the hydraulic power unit (because of breakage of the coupler between the motor and pump, suction filter 86 is clogged, thermal cut-out on motor M3 tripped, etc..) a signal will be transmitted to the microprocessor system which will stop the press.2.5.5

MAIN PUMP RUNNING - SAFETY BAR INTERLOCKS ACTIVATED (UP)

The microprocessor-based control system is energised along with the motor starters when the master switch is turned to its “on” position.

a)the following units start running when key “0” is pressed:-Fan motor in the sound-proof housing (if installed);

-Motor-and-pump assembly for the filtering unit and heat exchanger (M11-78).

The pressure in the filtering system is controlled by check valves 33. As a result, pump 78 is drained when pumps 58are not drawing in oil. Filters 79 and pressure switches SP1 and SP1s , which indicate when filter 79 is clogged, are located on the delivery line of pump 78.

b)if key “0” is pressed again (at least ten seconds must elapse between operations “a” and “b”), main pump and motor (M1-58) will start running.Unit M1-58 is started up at low pressure in a pre-determined sequence when solenoid valve YV309 controls pump drainage along with logic element 111. It takes approx. 1 minute to start motor M11, due to the high flywheel inertia,before which no operations can be performed.

Pressure switch SP3 and is installed on the suction line of pump 58. These are used to monitor pump booster. In fact,whenever there is a fault in pump 78, the pressure falls at the suction end of the pumps (the latter are therefore forced to draw the oil in through check valves 34). Pressure switch SP3 immediately indicates the pressure drop and stops the main motor pump assembly. A fault message appears on micro-processor control system display. When the two motors have been started up, the pressure in the main circuit of the hydraulic power unit is about 20 bar.

At the end of the start-up procedure, solenoid valve YV22s is energised and sends the oil to valves YV22a and YV22b .The latter keep the die-set in position.

2.5.6

POSITION TRANSDUCER - SETTINGS

The press is provided with digital transducers which continuously monitor the position of:- the plunger,- the knockout

- the mobile part of filler box CAF - the mobile feed hopper ALM

The press can control all operations as required by comparing the position of all moving parts (measured in real time)with data entered in the microprocessor control system by the operator.Encoders 1 and 2 (plunger position) “BQ6” and “BQ7”

The following settings can be entered for the plunger (see the Instructions B manual):- Plunger stoppage due to lack of powder

- End of braking position (position in which the plunger comes into contact with the powder)-Press-cycle start position (position in which the press-stroke starts)-Plunger raised position (automatic cycle)- End of braking during plunger upstroke

- Plunger parallelism error: this value, expressed in mm, indicates the maximum degree to which the plunger is inclined during the press-cycle Encoder 3 (filler box position) “BQ2”

The following settings can be entered for filler-box (see the Instructions B manual):- Position filler-box reaches when fully back - Position filler-box reaches when fully forward - Approach setting

- Filler-box speed during the forward stroke - Filler-box speed during the return stroke - Approach speed

- Filler box position for first die-set downstroke - Filler-box speed in manual mode

Sensor SQ2 will reset the encoder when energised by the cam. The latter is integral with the mobile part of the filler-box.Encoders 4 and 5 (knockout position) “BQ4” and “BQ5”

The following settings can be entered for the knockout (see the Instructions B manual):- Upper end-stops A and B - Speed during upstroke - Speed during downstroke

- Tile knockout between punches

- Knockout timing with filler-box during loading Encoder 6 (ALM position) “BQ10”

The following settings can be entered for the filler-box cycle (see the Instructions B manual):- Position ALM reaches when back - Position ALM reaches when forward - ALM speed during forward stroke - ALM speed during return stroke

- Position ALM reaches when the hopper gate is opened - Position ALM reaches when the hopper gate is closed

Sensor SQ10 will reset the encoder when energised by the cam. The latter is integral with the mobile part of the filler-box.

014AZ014A

2.5.7

SAFETY BAR INTERLOCKS DEACTIVATED (DOWN)

If the safety bar is lowered, the lock which prevents the plunger from being lowered is deactivated. Limit switch SQ51is deactivated while limit switch SQ52 is triggered, sending a signal to the microprocessor system.

As no signal to start operating is sent, the pressure in the hydraulic system will stabilise at around 20 bar. When a signal is received, the pump system is brought up to the required operating pressure set with proportional relief valves YV309.When valve 112 is set to a pressure of 350 bar , valve 111 acts as a hydraulic protection device. Remember that, once the pressure has been set to a safe level, it is good practice to lock the adjustment pins of the two valves by using the nuts. Otherwise the vibrations produced during operation may cause the pins to come loose and the set pressure to alter.The pressure level in valve 112 shall be referred to as “safety pressure ”.2.5.8

AXIS POSITIONING - TRANSDUCER RESETTING

To perform this operation, press keys 28 & 5 at the same time. This is to be done whenever the microprocessor based system is disconnected. The incremental position transducers must be reset in order to start machine cycling in automatic mode. “FILLER-BOX/DIE-SET/ALM ENCODER NOT RESET” will appear on the display of the microprocessor control system so as to inform the operator when this is to be done.

To position and reset, proceed as follows:- move the plunger fully up

- move the ALM right back to the reset sensor SQ10- move the filler box right back to the reset sensor SQ2

- move the die-set fully down to the encoder “zero” position (mechanical setting)

Once the above procedure has been completed, the microprocessor control system is ready to receive signals.2.5.9

DIE-SET CONTROL CIRCUIT

Press pushbuttons 13 & 25 to energise solenoid valve YV22s, YV25 as well as proportional valves YV22a and YV22b .Solenoid valve YV22s delivers oil to valves YV22a and YV22b which, in turn, supply oil to the two pairs of cylinders 180a1, 180a2, 180b1 and 180b2. The latter are used for the upward and downward movement. The cylinders on each side are joined to one another by an intermediate duct which ensures perfect timing. The pressure in the intermediate duct is restored by solenoid valves YV304a and YV304b . During each cycle the latter join the intermediate chambers to the reduced pressure line. This is accomplished through reducer 166.

In order for the cylinders to be precisely positioned, the pressure in the intermediate duct given on gauges 196 and 198must be as indicated on the plate. Check periodically. If this does not happen, proceed as directed in paragraph 4.2.2- INSTALLING AND REMOVING THE DIE-SET.

The speed and timing are controlled by the axis control card. The latter, in turn, is controlled by the microprocessor according to the position of the cylinders. Transducers BQ4 and BQ5 are used to monitor this position.

漂亮的英语书法字体非常漂亮的英语字体书法 同中国一样,也有着悠久的。英文书法包括安赛尔体、哥特体、意大利体和铜版印刷体等大类,下面带给大家的是漂亮的,希望你们喜欢。 同中国书法一样,英文书法也有着悠久的历史。中国书法我们知道有篆书、、、、等。而英文书法包括安赛尔体、哥特体、意大利体和铜版印刷体等大类,母体下又有各种子字体。 下面,揽云子按历史发展顺序一一介绍。 英文字母起源于腓尼基字母。希腊人继承发展腓尼基字母后,产生了希腊字母。罗马人后来又在希腊字母基础上发展成罗马字母(即拉丁字母,同斯拉夫字母和阿拉伯字母并称世界三大字母体系)。罗马帝国分崩离析后,各个文明自立门户,并相继发展自己的文字语言,英字也开始慢慢成长到今天的模样。由于篇幅有限,本文只抽取几种依然有实际应用和练习价值的几种字体。 罗马,哥特人是阿尔卑斯山北面一支日耳曼部落。西罗马帝国衰亡后,哥特人乘机建立法兰克王国,哥特体诞生于法兰克王国的加洛林王朝晚期。哥特体常见于中世纪教会文献、神学书籍以及官方文件。

漂亮的英语书法字体图片1_哥特体 中世纪晚期,欧洲兴起文艺复兴运动。该运动对欧洲文艺的改造是全方位的,包括写字的字体。而文艺复兴最先兴起于今意大利,而意大利人最先发明了这种字体,故名。 相比哥特体,意大利体显得奔放自由,书写便利性也极大提高了,颇具时代特色。以下为意大利体字帖。 渐渐地,随着历史社会发展和书写工具的改进,到16世纪,出现了铜版印刷体。铜版印刷体较意大利体,字形更加飘逸、优美、奔放。 斯宾塞体脱胎于铜版印刷体(copperplate),诞生于近代美国。同柳体一样,斯宾塞是以的名字命名的,他叫Platt Rogers Spencer. 斯宾塞体后来发展成美国商务书写字体。 以上所有字体笔画均有粗细变化,虽然看起来美观,但是写起来费时费事。于是,伟大的人民群众在斯宾塞的基础上发展出了商务

英文字母的书写规范

字体设计基础 (1)视觉均衡 (写在前面) 100%实用。这一系列关于字体设计的讨论文章来自https://www.wendangku.net/doc/9a6226759.html,,每篇文章都配有手绘的插图,以阐明字体设计的一些基本事项,指出设计新字体时可能会遇到的一些问题。这里只讲述一些最基础的东西,未涉及复杂的技术细节。为了让所有字符在视觉上对齐,它们就不能采用同样的物理尺寸。比如说,下图中的三角形的高度就必须大于矩形。否则,三角形看起来就要比矩形小很多。而我们在设计字体的时候,往往想给它们定义同样的高度。同样的,为了使圆形看起来和矩形同样大小,圆形就必须超出基线。如果圆形和矩形物理尺寸一样,圆形看上去就会比矩形小。这一规则不仅仅适用于三角形、圆形、方形这样的基本形状,这是字体设计的基本原则,整个字体中的所有字符都适用这一原则。不管你设计的是拉丁字体、还是斯拉夫或者希腊文字体,这是所有形体都必须遵循的基本准则。 (2)术语 使用字体的基本术语,会让设计过程中的交流变得非常容易。这里是一些基本的术语,让你的交流能够更深入,而不是“嗯,那里,那个,那个黑色的小玩意……”小写e的"字怀"(“字谷”)有时候也被称为是字“眼”,如果你还想更全面的了解其他术语,可以去图书馆,或者是参考下面的网络资源。(译注:很遗憾,原文中链接的一些资源已经无法访问了。但我们

可以用google找到其他的资源。这些术语很重要,如果你希望阅读西方的第一手的字体设计研究资料,这是必须跨越的一关。但目前在国内的设计界似乎还没有一个统一的翻译,不少书籍的翻译都是各行其是,让读者也无所适从。有时间我会找一篇比较完整的来翻译。) (3)流线型 流线型。设计字体就象开车。你在开车的时候,总是会以自然的曲线过弯。当你在纸面上绘制一条曲线(或是字符)的时候,也是同样的道理。曲线平滑的开始,而不是陡然出现。开车时,你不会在已经到达了弯道口之后才开始打方向盘,而是在你预计即将进入弯道的时候,就开始慢慢的将你的车引入正确的方向。当你在纸上画草图的时候,多想想你是怎样开车的。(下面有图片。) 图片上的文字: 标题:动态的曲线 左:怎样才能最快的驶过这条弯道? 右1:几何曲线 右2:自然曲线 右下:平滑的开始转向,更自然,更快速!

英文字体书写

书写艺术(art of writing)一般称为书法(penmanship/handwriting)。书写风格(style)通常就叫hand、script或alphabet。艺术性较高的书法一般称为calligraphy,更重视美感(aesthetics)与装饰效果(decorative effect)。古罗马(ancient Roman)书写风格包括行书(Roman cursive)、俗大字体(rustic capitals)与方块大字(square capitals)【现代大写字母(modern capital letters)的来源】。加洛林小字(Carolingian minuscle)在加洛林复兴时期占主导地位。哥特手写体(Gothic script)在十一世纪地位上升,直到意大利文艺复兴(Italian Renaissance)一直保持重要地位,有多种范本(copybook)。

Platt Rogers Spencer被认为是美国书法之父。他的方法长期在学校使用。十九世纪末,A.N.Palmer的范本开始流行。同时与Zaner和Bloser成立公司,到二十世纪八十年代,其教科书(textbook)占据书法类40%的销量。 Platt Rogers Spencer handwriting

A.N.Palmer handwriting 1976年出现两种新字体:D'Nealian script与Getty-Dubay。 D'Nealian cursive

手写体与印刷体

大家都知道,小写字母a和g有两种写法,如左右两个图里所示。有些人的第一反应是,一个是手写体,一个是印刷 体。可事实却不是这么简单,先解释一下左右两张图:左边是 Verdana 字体,右边是Times New Roman;上下三个字母里,最 下面这个是斜体。 把单层a (g)、双层a (g) 称为手写体a(g)、印刷体a (g)其实并不准确。手写体和印刷体是中文语境的通俗说法,引入拉丁文的时候,学写的字都是前者,后者只在铅字上见过。这说法其实并不准确。通常所谓的印刷体a,对应书法里的Humanist Hand。最早这种写法来源于文艺 复兴时期,因此这样命名。通常所谓的手写 体a,对应书法里的Italic Hand。Italic是指 西文中的斜体。最早印刷术里引入Italic这个 概念以及名称,为了和书写端正的Roman体区分,因此书法里作为斜体字原型的Italic Hand书写是带有一定角度的。严格来说,因为Italic体包含Italic hand 的风格特征,理应翻译成“意大利斜体”,仅仅翻译成斜体,损失的信息量太大了,而且也难以和普通斜体Oblique进行区分。 关于小写字母g 的两种写法,也有人把它们分别叫做open tail 和loop tail,手写一般用单层(single-story)g。一般正式出版物里面都用这种双层g 。不过很多电脑字体和非正式出版物都用单层g,所以单层g已经不能算仅仅是手写体了。 然后是小写字母a的问题,大多数印刷品和电脑字体里面,a 都是双层的,你可能会认为那种单层a肯定是手写体了吧?可惜不是,如果你去看报纸杂志,

你会发现所有斜体的地方a都是单层写法,如右图Times New Roman 字体所示。只不过很多电脑字体不遵守这个规则,只是简单的把正体 a 倾斜一下左图Verdana 字体,然而这种写法是不准确的。 有人也会问,大写G、J到底有没有横?我个人觉得那应该不算横,而是衬线,也叫做饰线。那么就有人问了,衬线是什么?我用一张图来解释好了。 我们先来看一看G、J“手写体”和“印刷体”的对比图吧。 然后再来看看F和T。 如果说G和J的饰线算是横线的话,那应该要像F和T的横线一样明确。那么又有人可能会问了,照我的说法,I的横线也应该是饰线了,那为什么我们在书写的时候要保留呢?据我搜索到的资料,I对饰线的保留是为了和小写的字

英语范文高中书法传统

英语范文高中书法传统 中新网客户端北京12月18日电(记者上官云)一张白纸、寥寥数笔勾勒出一个单词或者一句话……最近,几段有关“手写英文”的小视频在网上火了,字体之美令很多人感叹“不敢相信是手动完成的”,称之为“英文书法”。 手写英文作品。受访者供图 上述视频中,那些文字的作者叫韦钰琦,笔名“雨泣”,也有人称呼为他英文书法家。 生活中的韦钰琦,短发、戴眼镜,衣着干净整齐,平时不怎么爱主动跟人交流。但如果谈起“手写英文”,他便像打开了话匣子,滔滔不绝。 “高一时,我们英语老师说让大家练一下英文手写,对考试加分有帮助。”韦钰琦觉着有道理,字好看肯定讨阅卷老师喜欢,“那时练得也不错。后来在老师鼓励下,开始从网上找一些更好看的字体”。 韦钰琦的作品及使用的造型“奇特”的笔。受访者供图

偶然间,他在一个小论坛里发现了一些有关国外书法的资料,才知道写英文书法是需要专业工具的,普通的钢笔难以写出好看的字体,“第一次看到那些漂亮的书法,难以置信。接下来就是强烈的求知欲,想知道如何去写那么美的字”。 于是,韦钰琦充分发挥了动手能力强的特点,自制工具——“用老虎钳把普通钢笔笔尖剪掉或者剪平,就变成了平头钢笔,可以练习比较正式的书法字体。”升到高二,他终于用压岁钱从朋友那里买到人生第一套“点尖套装”。 大约在学习英文书法的第三个年头,韦钰琦把微信昵称定为“蘸水笔粉”,意思说自己是“蘸水笔”的粉丝,一直未改,“蘸水笔对英文书法的意义,就相当于毛笔之于汉字书法”。 用“点尖”手法绘制的羽毛。受访者供图 此后,韦钰琦慢慢“进阶”,逐渐成为别人口中的“英文书法家”。他译注了英文书法大师威利斯A·拜尔德的经典教程,今年11月,还出版《美丽的手写英文》一书,完整清晰地讲解了点尖英文字体ES(Engrosser’s Script),分享多年练字技巧。
