Abstract

The present invention relates to process of machining belt wheel for electromagnetic clutch. The belt wheel includes one casing, one bearing chamber, and one electromagnetic coil holder between the casing and the bearing chamber. The process of machining belt wheel includes the following steps: 1. punching steel plate material in a punch to form circular workpiece with central hole; 2. the first spinning in a spinning lathe with upper mold and lower mold to form the bearing chamber and the cylinder of the electromagnetic coil holder; and 3. the second spinning in the spinning lathe to form the belt slot in the casing. The process has environment friendship, high production efficiency and low production cost.

Description

technical field [0001] The invention relates to a processing method of a pulley, in particular to a processing method of an electromagnetic clutch shell pulley. Background technique [0002] As shown in Figure 1, the electromagnetic clutch housing pulley usually includes three parts: pulley housing 1, electromagnetic coil slot 2 and bearing chamber 3. There is a belt groove 11 on the outer edge of the pulley housing 1, and the central hole of the pulley is used as a bearing chamber 3, in which a bearing can be installed, and an electromagnetic coil groove 2 is provided between the bearing chamber 3 and the pulley housing 1 for Install the coil. The traditional processing technology usually uses 10# steel, first hot forging, then steel die forging, and finally using CNC machine tools for multiple turning processes. Due to the hot forging method, exhaust gas and dust are easily generated, which pollutes the environment. In addition, materials are wasted, the production effic...
