Abstract

The invention provides an automobile frame upper arm bracket production process. The automobile frame upper arm bracket production process includes the following process steps that a, materials are prepared in advance according to blanking specification models on a stamping operation instruction book; b, a designed blanking and punching die is installed on a stamping device for blanking and punching operation; c, a designed and manufactured edge turning die is installed on a machine tool, a part manufactured in the second step is placed in the edge turning die, and a first edge turning procedure is conducted; d, a special bending die is designed according to the bending shape of a part drawing and is manufactured and installed according to a designed die drawing, the part treated through the first edge turning procedure is placed in the special bending die so as to be bent; e, a designed and manufactured lateral punching die is installed on the stamping machine tool and the two sides of the die are laterally punched simultaneously; f, the special edge turning die designed and tested in advance is installed on the device to conduct a second edge turning procedure. By the adoption of the automobile frame upper arm bracket production process, product quality is easy to guarantee, the coaxiality of two lateral holes is good, a production period is short, production cost is low, and operation is convenient.

Description

technical field [0001] The invention relates to a machining process of cold stamping, in particular to a production process of an upper arm bracket of an automobile frame. Background technique [0002] The car frame is the chassis part that carries the body. The upper arm bracket of the frame is fixed on the side beam by welding. The upper arm bracket is U-shaped, and all three sides need to be turned. The two bracket feet on one side are inclined Extended out, there are two semi-circular arcs on the bracket, which are used for welding with the round tube parts on the side beam. There is a coaxial round hole on the left and right sides of the two bracket legs, which is used to install the connecting bolts. The coaxiality accuracy on both sides of the bracket is high, so the processing is difficult to achieve. Contents of the invention [0003] The purpose of the present invention is to provide a production process for the upper arm bracket of the automobile frame, which i...
