中文摘要

YB32-200型四柱液壓機(jī)適用于工件的壓制工藝，如沖裁、彎曲、翻邊、薄板拉伸等，也可從事校正、壓裝、砂輪成型、冷擠金屬零件成型、塑料制品及粉末制品的壓制成型工藝。
這臺(tái)液壓機(jī)由工作部分、機(jī)身部分和輔助部分組成。它的工作部分由工作油缸、活動(dòng)橫梁等組成，機(jī)身部分由上橫梁、工作臺(tái)和立柱組成，輔助部分包括頂出缸等。工作缸裝在上橫梁上，活動(dòng)橫梁和工作缸的活塞由螺母連接起來(lái)，以立柱為導(dǎo)向上下運(yùn)動(dòng)，對(duì)制件進(jìn)行壓力加工。液壓機(jī)由主缸驅(qū)動(dòng)上滑塊實(shí)現(xiàn)：快速下行→慢速加壓→保壓延時(shí)→快速回程→原位停止的動(dòng)作循環(huán)；由頂出缸實(shí)現(xiàn)：向上頂出→向下退回→原位停止的動(dòng)作循環(huán)。
這種液壓機(jī)有加工工藝簡(jiǎn)單、整機(jī)結(jié)構(gòu)簡(jiǎn)單、工藝性好等優(yōu)點(diǎn)。

Title  the design of YB32-200 hydraulic machine
abstract
This design of YB32 - 200 which has four pillar is a type of hydraulic machine that is applicable to the workpiece to inhibit a craft, such as hurtling to cut,curve,turning over a side,lamella to pull to stretch and so on,it can also be engaged in correct,press to pack,the emery wheel model,the cold crowded metals spare parts model,inhibit and model craft of the plastics product and the powder product.
   That hydraulic machine is constituted the work part,fuselage part and assistance part .Its work part is made up of the work oil urn,activity horizontal beam etc. the fuselage part is made up of ascend horizontal beam,the work pedestal and sign pillar. The assistance part includes an urn etc..The work urn packs up at the horizontal beam ,the activity horizontal beam connects with the piston of the work urn using the nuts,taking the pillar as signing to lead to the top and bottom sports,carrying pressure towards to the process to make a piece. hydraulic machine provide the main power in the mechanical transmission. totally,there is two hydraulic press be installedthe upset slidepart is drived by main hydraulic press,which help to function the following recycle of actions: go forward(high speed) → applying pressure(normal speed) → time delay → backhaul(high speed) → replacement.the second hydraulic press is designed to function another recycle of actions: push downwards → backhaul → halt.   
The hydraulic press in this design has the advantages of processing a craft simply and the whole machine structure simple, well craft and so on.

 Key Words:  hydraulic machine  pressing  economy
