Embodiment Construction

[0018] see figure 1 , a multi-station cold heading forming method for clutch conical blanks. The steel blanks are made into discs, which are respectively subjected to spheroidizing annealing, pickling, and wire drawing treatments, and are cut by an automatic cutting system to form a single clutch. The cone blank is formed into a clutch cone in a cold extrusion die, which specifically includes the following steps:

[0019] (1) Send the round finished material into the shearing mold through the feeding system, use the transverse shearing force of the scissors to cut, obtain a certain length of material, and use the clamp to send the cut material to the mouth of the first mold;

[0020] (2) Push the sheared material into the die by the punching tool. Since the head of the punching tool is in the shape of a processed raised step, the blank is flattened and placed on the front end by pressing the punching tool to apply pressure. Upsetting the inner chamfer positioning hole to form...

Abstract

The invention discloses a multi-station cold-heading molding method of a clutch conical blank. The steel billets are manufactured into wire rod materials, the wire rod materials are cut by using an automatic material cutting system after going through spheroidizing annealing, acid pickling and wire-drawing to form single clutch cone blanks, and the clutch cone molding working procedure is carried out in a cold-extrusion die. The invention greatly promotes the production efficiency and the product quality of the clutch cone, effectively saves the raw material and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of multi-station cold heading, in particular to the field of a multi-station cold heading forming method for a clutch conical blank. Background technique [0002] The clutch cone is a part of the brake clutch device in the bicycle. The existing bicycle clutch cones are all processed by car repair. Not only are there many procedures, the processing is difficult, the production efficiency is low, and the raw materials are greatly wasted due to various processes such as car repair and drilling. , the comprehensive performance of the product cannot meet the requirements of the domestic and foreign markets. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-station cold heading forming method for the clutch cone blank, so as to improve the production efficiency and product quality of the clutch cone, save raw materials, and reduce production cost...
