Double-work position automatic die-changing system for hydraulic press

Abstract

It relates to a hydraulic dual work station automatic mold changing system. It comprises tracks, mold changing cart, electric and pneumatic system, features in two mold work stations on the mod changing cart with each one fixed with chain passing grooves, guide track, guide stopper and spring pin to prevent the jumping of the mold plates, positioning device under the cart, crashproof device at both ends, middle connection platform between the track and the hydraulic machine, chain passing groove, guide track and stopper on the platform, delivery device at the other end of the track opposite to the connection platform, using front end hooking push and pull chains as the extraction tool for mold delivery and exchange. It is independent of the main of the hydraulic machine, reduces its structure, land occupation, auxiliary working period, meeting the need for processing parts of different specifications and kinds.

Description

technical field [0001] The invention belongs to auxiliary equipment of a press, in particular to a dual-station automatic mold change system for a hydraulic press. Background technique [0002] In the current known technology, the hydraulic press usually uses a single (station) mobile worktable or a multi-(station) mobile worktable to replace the mold. When a single mobile worktable is used, since it has only one station for placing the mold, The mold replacement operation can only be carried out after the previous pressure processing process is completed and the workbench is moved out of the hydraulic press, and it can only be carried out by manual assistance, so the mold change time is long. When using multiple mobile workbenches, although the mold change time is reduced, but It occupies a large area, and because the above two types of mobile workbench are used not only as the mold changing mechanism of the hydraulic press but also as the workbench, it is not only necessar...

Problems solved by technology

[0002] In the current known technology, the hydraulic press usually uses a single (station) mobile worktable or a multi-(station) mobile worktable to replace the mold. When a single mobile worktable is used, since it has only one station for placing the mold, The mold replacement operation can only be carried out after the previous pressure processing process is completed and the workbench is moved out of the hydraulic press, and it can only be carried out by manual assistance, so the mold change time is long. When using multiple mobile workbenches, although the mold change time is reduced, but It occupies a large area, and because the above two types of mobile workbench are used not only as the mold changing mechanism of the hydraulic press but also as the workbench, it is not only necessary to install the driving device required for movement on it, but also to increase the rigidity of the structure In order to withstand huge pressure, the structure of the mobile worktable is complex and heavy. In summary, they cannot meet the requirements of rapid mold replacement when forming and processing parts of different specifications and types, and the work efficiency is low.
