Embodiment

[0019] This embodiment provides a cold heading forming process for automobile steering system casing, which is specifically carried out in the following steps: 1. Prepare raw materials: cut the wire rod to the required length; 2. Pass the wire rod cut in step 1 through cold heading Upsetting is used for shaping, and grooves are formed at both ends of the wire; 3. The parts processed in step 2 are drawn through cold heading, so that the grooves at both ends of the parts are deepened to form concave holes; 4. The parts processed in step 3 The part is upset by cold heading to make the middle part of the part thicker; 5. The part processed in step 4 is subjected to secondary drawing by cold heading, so that one end of the part is elongated and the concave hole at this end is deepened, and the other end is The concave hole remains unchanged; 6. The parts processed in step 5 are finished and transferred through cold heading, so that the spacer between the two concave holes of the par...

Abstract

The invention relates to a cold heading molding process for vehicle steering system sleeves and a cold heading module. The cold heading molding process for the vehicle steering system sleeves molds the vehicle steering system sleeves and cold heading module through shaping, primary broaching, upsetting, secondary broaching, finish shifting and through hole penetration by the cold heading module after shearing of wires. The cold heading module is a six-mold six-punch cold heading mold, and comprises a first mold for shaping, a second mold for primary broaching, a third mold for upsetting, a fourth mold for secondary broaching, a fifth mold for finish shifting and a sixth mold for through hole penetration. The cold heading molding process for the vehicle steering system sleeves and the coldheading module adopt the cold heading mode to machine the sizes of the sleeves and inner holes to achieve material saving, complete metal flowing line, improvement of the part strength, reduction of machining procedures, improvement of the machining efficiency; and the adopted cold heading module is simple in structure, easy to operate and high in production efficiency.

Description

technical field [0001] The invention relates to the field of manufacturing automobile steering system sleeves, in particular to a cold heading forming process and a cold heading module for automobile steering system sleeves. Background technique [0002] Such as image 3 The automobile steering system bushing shown in the prior art is generally formed by automatic machining of pipes. This method has low efficiency, long production cycle, high waste of materials, incomplete metal flow lines, low strength of parts, and the The tool life used is not high, increasing production costs. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a cold heading forming process and cold heading module for the casing of the automobile steering system. All dimensions and inner holes of the casing of the automobile steering system are processed by cold heading , not only saves materials, but also has complete metal streamlines, i...
