Embodiment Construction

[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 in conjunction with the accompanying drawings and best implementation examples.

[0021] Such as figure 1 Shown, the present invention comprises the following steps:

[0022] (1) Shaping: the round steel is unrolled and cut to a fixed length, and the cut round steel is extruded through a die to shape it into a square cylinder; after step (1) shaping, the cut stubble of the workpiece a is cold-extruded to form a regular shape hemispherical;

[0023] (2) Shaping and centering: the workpiece obtained in step (1) is extruded and shaped into a square cylinder, and one end of the hemispherical shape is extruded into a square center hole to prepare for the next process of extruding a square hole. After step (2) the workpiece b is shaped, the edge of the other end is rounded;

[0024] (3) Necking an...

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...
