The second transverse hydraulic cylinder stretch out, gripper complete grasping movement pickup, then PLC control right side the first transverse hydraulic cylinder makes right side
Gripper be retracted into suitable position, control PLC makes turntable rotate 180 °, and adjusting vertical hydraulic cylinder and the first transverse hydraulic cylinder makes
The gripper of grip reaches suitable position again, and control the second transverse hydraulic cylinder contraction opens gripper, workpiece is put into down
In Mod correction mould, adjusting the first transverse hydraulic cylinder makes to stretch out gripper rollback, moves upper baffle plate down by PLC, when solid
Fixed board touches the fixed plate positioning column period of the day from 11 p.m. to 1 a.m, and fixed plate and the stopping of upper mold straightening die move down, and at this moment, upper mold straightening die is under
Mod correction model cavity clings to workpiece completely, and upper baffle plate continuation moves down, to which upper mold trimming is framed and punch. contact
To after workpiece, excision overlap and punching are carried out, punched scrap is directly gone out in the outer iron frame of device by lower mould bottom plate discharge hole, general
Overlap waste material after logical spring is trimmed presses down, and when upper baffle plate up returns, common spring can be released stress, overlap with
Workpiece up ejects together, and after touching the two-way positioning column of common spring, common spring stop motion, trimming waste material is easily
Abjection, and product can be sticked after formed punch punching simultaneously, after plate to be fixed is detached from fixed plate positioning pillar, nitrogen gas spring can rebound,
Fixed plate is pushed away down, formed punch can return in the first punching, product can be taken off easily in this way, in trimming, punching, correction
In the process, pickup process is repeated by the another gripper completion on PLC control right side, then the gripper in control left side will add
The good workpiece of work is fetched, and after 180 ° of rotation, the workpiece processed is put into scene charging iron frame.
The beneficial effects of the invention are as follows trimming, punching, correction is completed at the same time, artificial loading and unloading are not needed, safety coefficient is high,
It is high-efficient, and convenient disassembly.
