Five or six gear shifting yoke bending die of automobile

Abstract

The invention discloses a five or six gear shifting yoke bending die of an automobile, which belongs to the technical field of die design. The five or six gear shifting yoke bending die comprises a concave die, a convex die, a convex die fixed plate, a workpiece and a concave die fixed plate, wherein a counterbore is formed in the middle of the concave die, the concave die and the concave die fixed plate are fixed into a whole by adopting a welding mode, and the connection is firm; during processing, the workpiece is put into the counterbore of the concave die, and the workpiece which is put into the concave die is forged and pressed by the convex die; and the convex die and the convex die fixed plate are fixedly connected by adopting the welding mode, the convex die fixed plate is fixed to a forging head of a forging machine, and the forging head moves up and down so as to drive the convex die to forge a workblank of the workpiece, so that the required shape of the workpiece is formed. According to the five or six gear shifting yoke bending die of the automobile, the workpiece is conveniently formed, the convex die and the convex die fixed plate are reliably fixed, the concave die and the concave die fixed plate are reliably fixed on a workbench, the position of the concave die fixed plate can be adjusted, and the processing accuracy of the workpiece is high.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to a bending mold for fifth and sixth gear shift forks of automobiles. Background technique [0002] At present, when producing forging parts with complex shapes, most of the various processes are completed by independent multiple equipment. Due to the large number of equipment used, it is easy to consume forging mold bases and increase the usage of molds, resulting in mold costs and The production cost is very high, the workpiece is troublesome to form, the machining accuracy is low, the concave and convex molds are not reliable, and the production efficiency is low. It is necessary to adjust the bending mold of the fifth and sixth gear shift forks of the car. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of troublesome workpiece forming, low processing precision, unreliable fixing of concave and convex molds and low produ...
