An adjustable mold base and powder forming and shaping machine with the mold base

Abstract

The invention provides an adjustable mould holder and a powder forming and shaping machine with the mould holder. The mould holder comprises a mould holder support, a stroke unit and a first adjustment unit; the stroke unit is connected with the mould holder support and is used in forming of a workpiece; and the first adjustment unit is connected with the mould holder support and is used to adjust stroke of the mould holder. The first adjustment unit in the adjustable mould holder is used to solve the problem of a micro height difference which exists between a workpiece while one-step forming and a finished product and which is resulted from machining precision of the mould holder or an error generated due to existing of a metal powder resilience force in a machining process after workpiece one-step forming, and the first adjustment unit finely adjusts the stroke of the mould holder in this way to enable a machining precision requirement to be achieved at the next time of workpiece forming. The structure of the first adjustment unit is simple, operation is convenient, and stability while workpiece stamping is high; and time for adjusting the stroke of the mould holder is short, rigidity is good, and reliability is good.

Description

technical field [0001] The invention relates to a mold base, in particular to an adjustable mold base and a powder forming and shaping machine with the mold base. Background technique [0002] The mold base is a bracket used to manufacture the mould. In the use of the mold base in the prior art, the structure of the mold to be formed is firstly adjusted, and then put into the powder forming machine to work. [0003] Please refer to the Chinese patent "A Cylinder with Adjustable Stroke", application number: 201210449520.1, the present invention discloses an oil cylinder with adjustable stroke, which includes a cylinder body, a cylinder head, a piston rod, a piston connected to the piston rod, and a rodless oil chamber. It is characterized in that there is a mounting seat fixedly connected to the front end of the cylinder body, and the mounting seat is provided with a worm screw and a worm gear meshing with the worm screw through a bearing, and a stroke positioning sleeve is p...

AI Technical Summary

Problems solved by technology

[0008] The first adjustment unit in the adjustable mold base of the present invention is used to solve the error caused by the processing accuracy of the mold base or the existence of the rebound force of the metal powder during the processing after the workpiece is formed once, resulting in the There is a small amount of height difference between the workpiece and the finished product during one forming, so the stroke of the mold base is slightly adjusted through the first adjustment unit, so that the next time the workpiece is formed to meet the processing accuracy requirements, the second An adjustment unit has a simple structure and is easy to operate. The workpiece is relatively stable during punching, and the time for adjusting the stroke of the mold frame is relatively short, which improves work efficiency, lower processing costs, and has good rigidity and reliability.
