Example Embodiment

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and best implementation cases.

[0021] Such as figure 1 As shown, the present invention includes the following steps:

[0022] (1) Shaping: Unwind the round steel and cut it to a fixed length, and extrude the cut round steel into a square cylinder through a die; Step (1) After shaping the workpiece a, the cut stubble is cold-extruded to form a regular Hemispherical

[0023] (2) Shaping and centering: the workpiece obtained in step (1) is extruded and shaped by a die to form a square cylinder, and one end of the hemisphere is extruded into a square central hole to prepare for the next process. Step (2) After shaping the workpiece b, the other end edge is rounded;

[0024] (3) Neck-extruded rectangular hole: the workpiece prepared in step (2) is squeezed int...

Abstract

The invention relates to the production field of mechanical parts with a cold extrusion forming technology, in particular to a cold extrusion processing method for a coupling fork. The processing method comprises the following steps of shaping, shaping, squaring and centering, necking and extruding of a square hole, extruding of a threaded hole, trimming and perforation; an original cutting technology or casting technology is replaced, and the production technology has the advantages of high utilization rate of raw materials, energy saving and environmental protection, and the energy consumption is reduced by 80% or above than the energy consumption of the original technology; and the coupling fork prepared with the production technology has the advantages of higher quality and density andexcellent mechanical property after the coupling fork is subjected to extrusion treatment.

Description

technical field [0001] The invention relates to the field of production of mechanical parts using a cold extrusion molding process, in particular to a cold extrusion processing method of a coupling fork. Background technique [0002] Coupling fork is a widely used standard part, such as used in the connection of automobiles, agricultural machinery, construction machinery and mechanical equipment. Traditional connecting forks are produced by cutting and mold casting. This method consumes a lot of energy and pollutes in the process of processing and casting. Today, the country's requirements for environmental protection are further improved, and the production process of connecting forks is obvious. Needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide an innovative processing method for the coupling fork—cold extrusion molding process. [0004] The p...
