Description
Technical Field
[0001] The utility model relates to the technical field of correction devices, in particular to an auxiliary correction device for wire cutting processing of mold parts. Background Art
[0002] Wire cutting belongs to electrical machining. Its basic machining principle is to use a moving metal wire as a tool electrode, pass a pulse current between the metal wire and the workpiece, and use pulse discharge to corrode the workpiece. It can process narrow slits and grooves. Due to the special shape and structure of some mold parts, wire cutting technology is required to complete the processing. In order to ensure the accuracy of the processing position, certain auxiliary correction work is required before fixing with professional fixtures.
[0003] The common correction device has a relatively simple structure. It simply fixes the parts to be processed and then clamps them with other fixtures. During this process, the position of the parts may shift due to external collisions, and the overall correction effect is poor. This may affect the subsequent clamping effect and thus have an adverse effect on the wire cutting process.
[0004] For example, Chinese patent CN214769516U discloses an auxiliary correction device for wire cutting of mold parts. The limit mechanism cooperates with the screw-driven pressure plate part to assist in the correction of the mold parts placed on the base, and the limit plate structure is strengthened. In conjunction with the auxiliary buffer mechanism on the push plate, the device can steadily push and correct the mold parts while facilitating fixation with professional fixtures. The overall operation is simple and easy to implement, and can avoid the displacement of the parts position during the correction and fixation process, thereby ensuring the subsequent wire cutting processing effect.
[0005] However, the device is unable to limit and fix the front and rear sides of the part during use, causing the part to shift to the front and rear sides when it is bumped, affecting the subsequent clamping and wire cutting processing effects.
[0006] For this reason, we urgently need to provide an auxiliary correction device for wire cutting processing of mold parts. Utility Model Content
