Flat annulus filling shapes mould design

4) reach introvert arc muscle piece structure (if be part drawing) , performance is consequently superior, can reduce a tie anxious, reduce an axis to mix, decrease pressure fall, conduce to raise processing further ability and pass qualitative efficiency, it is a kind of new-style tower filling that has wide market demand. Craft of 2 spare partses analyses flat annulus filling is what by 5 paragraphs circular arc comprises one kind is quincuncial, material is stainless steel. Following curving use to shape previously craft: Bend (curve circular arc of two upright inside and outside to reach two upright bend) just a little second bend (bend circular arc of intermediate inside and outside) shape. Because stainless steel material suffers force hind intensity to increase apparently, and bend 2 times reach when shaping cannot locate accurately, make a presence finally the mouth is big, 5 paragraphs of circular arc distributing blemish of not equal quality, need to expend many artificial plastics. Produce to rise efficiency and improve product quality, the hope can shape (intermediate small claw can shape naturally) . Additional, because shape sunken model must ordinal movement, shape core axis from reach the designated position to shape finally to workpiece between need has interval of period of time. 3 moulds structure and working process are like plan institute to show, mould by shape core axis, installation, the composition such as two groups of inclined wedge and bedspring. Shape core axis, installation, bedspring forms one float structure. When be issued to lower levels of punching machine slide block, drive shape core axis be issued to lower levels presses next workpiece to semifinished product and sunken model I are contacted and bend among paragraph circular arc of inside and outside shapes; Then, inclined wedge urges sunken model campaign, bedspring is compressed, shape core axis photograph is not moved to sunken model I, bend to shape with two paragraphs of circular arc of adjacent of photograph of arc of intermediate Duan Yuan; Finally, what inclined wedge I drives motion of sunken model I to complete work is final shape. When punching machine slide block goes up, order of mould movement movement is contrary. Mould of point of 4 moulds design should assure to shape after core axis reachs the designated position, move downward no longer, hold period of time, in order to avert generation interference. For this, will install with installing plate (package) the design is float. The height that height of workpiece of float journey basis and sunken standard issue on beforehand set. The choice of bedspring should satisfy two requirements: The first, next work semifinished product can be controlled when be issued to lower levels of punching machine slide block and bedspring does not arise compress; And when punching machine slide block goes up, make shape in set travel a planted agent core axis not as go up, in order to assure a standard. The 2nd, permission compression measures the requirement that should satisfy the journey. Transfer piece action is to assure when to sunken model is moving, be not locked up dead. The 5 problems that should note should make sure when designing a pattern installing plate can locate reliably, in moving, direct effectively (can add guide pillar to direct) . Because whole exercise process includes bedspring to reduce the travel, special attention answers when choosing a machine tool the journey that machine tool journey should satisfy a mould to design place to need is measured (be equal to mould place to need the journey to add bedspring to reduce the travel) . 6 epilogue require the travel as a result of mould place bigger, limitted the suitable scope of the mould consequently. But the course is used actually a year, prove this mould structure is produced to rising efficiency and assuring product quality is very practical. (on receive the 296th page) right fall to be controlled to 120 ° C, improved heat exchange result, narrowed axial difference in temperature. 4.

4 improve water injecting pump model will former instead of chestnut of 3 force plunger 2 multistage are centrifugal chestnut, assure to sail upstream goodly on one hand state, increased the flow of cooling medium on the other hand, made sure hydrogenation reactor has enough soft water between the canal, prevented to be caused because of lacking water " fly lukewarm " the phenomenon of burned-out activator. 5 epilogue adopt the analysis that has many sided reason to activator of benzene hydrogenation reaction and adopted corresponding step, temperature of hydrogenation reaction heat is smooth, annulus personal alkyl crop is compared with the photograph before improving, have very big rise, annual personal alkyl crop all achieves annulus 11 life and equipment carry surround cycle to be able to lengthen (see a table 2) , those who reduced hydrogenation process stay car time, obtained regular economic benefits. Express 2 activator to use cycle to express prime time to produce time equipment operational cycle / month CNC Milling CNC Machining
