Technology for cold rolling extrusion teeth of cylindrical end face

Abstract

The invention relates to a technology for cold rolling extrusion teeth of a cylindrical end face. The technology comprises the following steps that 1 a rolling tool is prepared, wherein the rolling tool is a hollow circular truncated cone adopting alloy steel as materials, and the outer surface of the rolling tool is provided with rack-shaped blades; 2 a to-be-machined workpiece is fixed in a fixture of a lathe, the rolling tool is inserted in a tool bar in a penetrating mode, and the tool bar is fixed on a carriage; 3 a machine tool is started, the revolving speed of the fixture is regulated to be at 1000 r to 1800 r, the carriage provided with the rolling tool is pushed to the direction of the end face of the workpiece to enable the outer surface of the rolling tool to make contact with the end face of the workpiece, and the rolling tool makes contact with the end face of the workpiece for three to five seconds under the environment of 30-kilogram force; 4 the carriage is loosened, the workpiece is taken down, the machine tool is switched off, the whole process is over, and machining of a small tooth face of the end face of the workpiece is completed. According to the technology for cold rolling extrusion teeth of the cylindrical end face, automation is achieved in the whole process, the defect that a traditional technology has to perform machining through mechanical equipment machining such as planing equipment and milling equipment is overcome, machining investment is small, and efficiency is high.

Description

technical field [0001] The invention relates to a process for processing a cylindrical end face tooth, in particular to a process for cold rolling and extruding a cylindrical end face, and belongs to the technical field of mechanical processing procedures. Background technique [0002] In the mechanical parts we use, especially the specific parts in transportation machinery such as automobiles, airplanes, and trains, in order to prevent sliding, causing parts to fall off and causing accidents, there will be a small tooth surface on the end face of such parts. The traditional process is processed by mechanical equipment such as planing and milling. This kind of processing requires a lot of investment and low efficiency. Each piece of this equipment costs more than tens of thousands, and the process is complicated. It is labor-intensive for the operator, and the processed teeth are not On average, the teeth have to be planed out one by one, and the daily output can range from ...
