Device and method for bush rolling and unloading tooling

Abstract

The invention discloses a lining edge rolling discharge tooling device. The device comprises a base plate, wherein a front supporting seat and a back supporting seat are mounted on the base plate in parallel; the front supporting seat and the back supporting seat are connected through at least two guide rails which are side by side arranged, and a slide plate is arranged between the front supporting seat and the back supporting seat; the slide plate movably sleeves the guide rails, and the slide plate is connected with the back supporting seat through a driving assembly, and can be driven by the driving assembly to move forwards and backwards; a rotating device is fixedly mounted on the slide plate, the front end of the rotating device is coaxially connected with a horizontally arranged edge rolling model shaft through a coupler; a gear fork is fixedly arranged at the front end of the front supporting plate; the front end of the edge rolling model shaft successively penetrates through a through hole of the front supporting plate and a fork opening of the middle part of the gear fork; a material falling raceway is horizontally mounted at the front end of the gear fork; the through hole of the front supporting plate is a T-shaped hole, and a model guide flange is fixedly mounted in the T-shaped hole; and the edge rolling model shaft is matched with the through hole in the model guide flange in a sliding manner. The device can well replace the manual rotary edge rolling model shaft, and has the advantages of reducing the labor intensity of workers and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of workpiece forming machinery, in particular to a bush rolling and unloading tooling device and method. Background technique [0002] The bushing is a ring-shaped structure, which is used in the bearings of the automobile power system to reduce the wear of the bearings. An important link in the processing of the existing bushing is exactly rolling, that is, the sheet metal is rolled into a ring-shaped bushing blank. In actual production, due to the insufficient elasticity of the metal sheet itself and the insufficient precision of the mold, the roundness of the joints of the bushing after one round cannot meet the requirements. In order to ensure that the roundness of the bushing meets the requirements, the worker needs to hold the rolling die shaft to rotate. Stamp the workpiece in two to three directions. This traditional processing method has high labor intensity and low processing efficiency, and if workers are...

AI Technical Summary

Problems solved by technology

In actual production, due to the insufficient elasticity of the metal sheet itself and the insufficient precision of the mold, the roundness of the joints of the bushing after one round cannot meet the requirements. In order to ensure that the roundness of the bushing meets the requirements, the worker needs to hold the rolling die shaft to rotate. Stamping the workpiece in two to three directions

This traditional processing method has high labor intensity and low processing efficiency. Moreover, once workers are negligent in the process of continuously rotating the rolling die shaft, it is very easy to cause safety accidents and cause serious personnel and property losses.

At the same time, the strength and wear resistance of the existing rolling die shafts cannot meet the industrial requirements. Some rolling die shafts cannot guarantee the wear resistance when the strength is increased, which has become a short board for the service life of the device.
