A fast-change high-precision positioning and locking device and method for one-out multi-mould compression mold

Abstract

The invention discloses a rapid-to-replace high-precision-positioning locking device for one-out multiple-die-pressing dies and an application method of the rapid-to-replace high-precision-positioning locking device. The locking device comprises an integrated upper punching fixture and an integrated lower punching fixture, the upper punching fixture can be used for being connected with upper punches, and the lower punching fixture can be used for being connected with lower punches. A plurality of connecting portions used for individually mounting the upper punches and the lower punches are arranged on each of the upper punching fixture and the lower punching fixture. Each connecting portion is provided with a positioning portion and a locking portion, the positioning portions are used for positioning the corresponding upper punches and the corresponding lower punches, and the locking portions are used for fixing the corresponding upper punches and the corresponding lower punches. The locking portions are arranged on the lateral sides of the positioning portions, and lock the upper punches and the lower punches both put in the corresponding positioning portions. The locking device can rapidly clamp and accurately position a plurality of punches, solves the problems such as long die changing time, low die mounting accuracy and high labor intensity of existing die-pressing dies, and has the advantages that positioning accuracy of each punch is high, the punches are rapid to mount and demount, load bearing capability is high, the locking device is safe and reliable, simple in structure, low in cost and simple to operate, and the like.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy molding compression forming, in particular to a quick-change high-precision positioning and locking device for one-out multi-molding molds and a method thereof. Background technique [0002] Powder metallurgy is a material preparation technology that mixes metal powder and non-metal powder or metal powder and metal powder through ball milling, forming, and sintering to make powder metallurgy products—parts or tools. Because it has the characteristics of producing multiple sets of raw materials, complex forming shapes, hard alloys and refractory materials, and high forming dimensional accuracy, it is widely used in machinery manufacturing, automobiles, electrical appliances, aviation and other industrial fields. Compression molding is the most commonly used forming method in powder metallurgy. [0003] Whether it is the forming of cemented carbide or the pressing and forming of other pow...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a quick-change high-precision positioning and locking device and method for multi-molding dies, which can realize fast clamping and accurate positioning of multiple punches, and solve the problem of existing molding dies. The problems of long mold changing time, low mold loading precision, and high labor intensity have the advantages of high positioning accuracy of each punch, fast loading and unloading of punches, large load carrying capacity, safety and reliability, simple structure, low cost, and easy operation.
