Tensile pressure testing machine for batch pressing and method for realizing batch pressing of workpieces

Abstract

The invention relates to a tension and pressure testing machine for batch pressing and a method for realizing batch workpiece pressing. The tension and pressure testing machine includes an upper beam, a base, N groups of force value control units, N force value control systems and N hydraulic control units. system; each group of force control units includes a hydraulic pump and a force sensor set on the top shaft of the hydraulic pump; the hydraulic pump is set on the base, and the top of the force sensor is used to fix the workpiece to be pressed; the force control system is used to receive The feedback data of the force sensor is used to control the output of the hydraulic pump through the hydraulic control system according to the feedback data. Through the pressing force fed back by the force sensor, the hydraulic pump automatically adjusts the height of the workpiece base to ensure that the pressing force of each seal is a standard force value, which solves the problem of low production efficiency of existing equipment and insufficient force for pressing multiple workpieces at one time. The problem of uniformity and many defective products has realized batch pressing, high production efficiency, accurate force value output, and has very good application value and promotion value.

Description

technical field [0001] The invention relates to a tension-pressure testing machine, in particular to a tension-pressure testing machine capable of batch pressing. Background technique [0002] In view of the background of the current national quality improvement, the requirements for the production process are getting higher and higher in the production process. The process requirements for sealing parts pressing in a certain type of production task are changed from pressing under a certain standard force value for ten minutes to the standard force value. Pressed under conditions for forty minutes. At the same time, the total amount of production tasks is still increasing year by year. Originally, each tension-compression universal testing machine can only load one workpiece for pressing at a time, which can no longer meet the existing production needs. It is not a good solution to increase the tensile and compression universal testing machine in large quantities, which is ...

At the same time, the total amount of production tasks is still increasing year by year. Originally, each tension-compression universal testing machine can only load one workpiece at a time for pressing, which can no longer meet the existing production needs.

It is not a good solution to increase the tension and compression universal testing machine in large quantities, the cost is high
