Numerical control upsetting tester

Abstract

The invention discloses a numerical control upsetting tester, comprising an industrial personal computer (IPC) and a tester mainframe, wherein the tester mainframe comprises a tester lathe bed and left, right and longitudinal three-axis numerical control driving devices which are installed on the tester lathe bed and are arranged in inverse T shape relative to each other; the right and longitudinal driving devices have the same structure and both comprise stepping motors; the stepping motors are connected with the right part of a drive shaft; a flange on the drive shaft is connected with the right end surface of a sensor seat tube; the left part of the drive shaft is connected with the sensor seat tube by a key; a load sensor is installed in the sensor seat tube; a shaft head on the left of the sensor seat tube is connected with a shaft head of a ball screw; a ball screw nut is fixed with a right upsetting or bending die holder; and the two sides of the die holder are connected with the lathe bed by slide rails. The device can carry out scale simulation test on the upsetting forming process of large forgings and efficiently verify the rationality of the upsetting forming process and die design at low cost.

Description

technical field [0001] The invention relates to a testing machine, in particular to a numerically controlled upsetting testing machine. Background technique [0002] The upsetting and forging process of large forgings such as large crankshafts, marine stern shafts, and fan speed-increasing shafts is difficult and costly. Unreasonable forming process will lead to quality problems of forgings, even scrapped, resulting in huge economic waste. Therefore, process experiments must be carried out before production. The proportional simulation process experiment based on the similarity criterion has the advantages of high reliability, short experiment period, low cost, safety and reliability, etc. effective method. Large crankshafts, marine stern shafts, fan speed-increasing shafts and other large-scale forgings forging and forging proportional simulation process experiments have the following functional requirements for experimental equipment: (1) Three-axis linkage control; (2)...

AI Technical Summary

Problems solved by technology

The upsetting process test of forgings such as large crankshafts may be replaced by costly production practices, or realized by supplementing simple process devices on general-purpose presses, both of which are difficult to meet the needs of upsetting process research, such as accurate measurement of load-stroke curves , any precise position to stop or continue the test, etc.
