Multi-mould replacement system of vehicle body hemming machine

Abstract

The invention relates to a multi-mould replacement system of a vehicle body hemming machine, in which a single press is equipped with a plurality of moulds, the moulds can be replaced quickly and the layout is reasonable; the multi-mould replacement system of the vehicle body hemming machine overcomes the defects of the prior art that one station corresponds to one mould, the occupied space is large, the mould replacement time is long, and the mould replacement is easily restricted by inadequate site space, hosting conditions and the like are overcome; a punch mould device comprises a workbench and a mould which is fixed on the workbench; a replacement mechanism comprises a punch station and a reserve station which is arranged around the punch station; the reserve station is connected with the punch station through a walking rail; the workbench is arranged on the walking rail; and a control system comprises a general control mechanism and an independent driving mechanism which is arranged on the workbench and is connected with the general control mechanism. The punch station is integrated with the reserve station, a closed structure in which the reserve station encloses the punch station is formed, the occupied site area is small, the space utilization rate is high, various work pieces can be punched and processed at the same station, the arrangement of procedures is reduced, the work piece processing efficiency is improved, and the transportation of the work pieces among the stations is omitted.

Description

technical field [0001] The invention belongs to the field of press mold layout and mold changing technical device, in particular, a single press is equipped with multiple molds, which realizes quick mold change without crane hoisting, and can change multiple sets of molds for a car body hemming machine with reasonable layout. Modular system. Background technique [0002] The workpiece of the edge wrapping machine (belonging to the stamping machine) will have more molds to cooperate during processing. Different workpieces also need different molds. Different molds will have their own fixed installation position. Generally, traditional stamping molds are one The station is equipped with a set of moulds. When processing, the mold for the workpiece is selected according to the workpiece. Multiple molds require multiple fixed spaces, which will occupy and increase the space of the factory building, that is, it is necessary to expand the space of the factory building to accommodat...

Problems solved by technology

[0006] The invention solves the disadvantages in the prior art that one station corresponds to one set of moulds, which takes up a lot of space, takes a long time to change molds, and is easily limited by insufficient space on the site and installation and lifting conditions. It provides a collection type, and multiple sets of molds correspond to one The machine press station (hereinafter referred to as the station) has a high space utilization rate and a high equipment utilization rate. Multiple sets of mold change systems for the body hemming machine

[0007] The invention solves the disadvantages in the prior art that the different molds required by different workpieces are independently dispersed and fixed, occupying a large space and easily causing complicated workpiece processing procedures, and provides a kind of multiple sets of molds corresponding to one station, and the processing of different workpieces is arranged in one Stations, reducing logistics handling, mold selection and other links. Multiple sets of mold change systems for body hemming machines

[0008] The present invention also solves the disadvantage that the existing single stamping station is equipped with only one set of molds and cannot be expanded, and provides a multi-set car body hemming machine that can expand the existing mold system and has relatively low space requirements Mold change system
