The 4 and 8 ribs around the motor shaft are usually processed by the motor shaft punching machine?

The 4 and 8 ribs around the motor shaft are usually processed by the motor shaft punching machine. The following is the specific manufacturing process:

Equipment preparation

• Choose the appropriate punching machine: Based on the size, material, and production batch requirements of the motor shaft, choose the appropriate motor shaft punching machine. The TB12-22-480 fully automatic punching machine for motor shafts is suitable for motor shafts with a diameter of 8-12mm and a total length of 330mm or less; The TB12-25x350 hydraulic punching machine is suitable for motor shafts with a diameter of 12-25mm and a total length of 230mm or less.

• Equipment inspection: Before use, a comprehensive inspection of the reinforcing machine should be conducted, including the stability of the body, the normal operation of the electrical system, the accuracy and reliability of the stamping system, and the smoothness of the automatic feeding system, to ensure that the equipment is in good working condition.

Mold making

Design mold: Design a mold that matches the size, shape, and required number, size, and distribution of ribs of the motor shaft. For 4 and 8 bars, it is necessary to accurately calculate the position, angle, and size of the bars to ensure that the punched bars are evenly distributed and meet the design requirements.

• Mold making: Molds are usually made of materials such as hard alloys or high-speed steel, which have high hardness and wear resistance, ensuring the service life and stamping quality of the mold during the stamping process. The precision requirements for mold production are high, and precise processing equipment and techniques are needed to ensure the dimensional and shape accuracy of the mold.

• Choose the appropriate motor shaft material: Generally, motor shafts are made of steel, such as 45 steel, which has good mechanical and processing properties and can meet the strength and wear resistance requirements of the motor shaft.

• Pre treatment of motor shaft: Clean and rust the surface of the motor shaft to remove impurities and oil stains, ensuring good contact between the mold and the motor shaft during the stamping process and improving stamping quality.

Stamping processing

• Clamping motor shaft: Place the pre treated motor shaft into the fixture of the punching machine, and firmly fix the motor shaft with the fixture to ensure that the motor shaft will not shift or rotate during the punching process.

Adjust stamping parameters: Adjust the punching force, punching speed, punching stroke and other parameters of the stamping machine according to the material, size and rib requirements of the motor shaft. The punching force should be moderate. Excessive pressure may cause deformation of the motor shaft, while insufficient pressure may prevent clear ribs from being punched out; The stamping speed should be determined based on the material of the motor shaft and the durability of the mold. If it is too fast, it may affect the stamping quality, while if it is too slow, it will reduce production efficiency; The stamping stroke should be precisely controlled to ensure that the height and shape of the stamped ribs meet the requirements.

• Stamping: Start the punching machine, and under the action of hydraulic or mechanical force, the punch punches the motor shaft according to the set parameters, stamping the material around the outer diameter of the motor shaft into the required 4-bar or 8-bar shape. During the stamping process, it is important to closely observe the stamping situation and promptly identify and address any potential issues, such as displacement of the motor shaft, damage to the mold, or non-conforming bars produced by stamping.

Subsequent processing

Remove burrs: The motor shaft ribs after stamping may have burrs, which need to be removed using grinding tools to ensure the smoothness and accuracy of the motor shaft surface.

• Heat treatment or surface treatment: Punching processing may reduce the hardness of the motor shaft. In order to improve the hardness and wear resistance of the motor shaft, it is necessary to perform heat treatment such as quenching, tempering, or surface treatment such as chrome plating, carburizing, etc.

• Inspection and repair: Use professional inspection equipment to inspect the stamped motor shaft, check the position, size, shape of the ribs, and whether the roundness, straightness, etc. of the motor shaft meet the design requirements. If any non compliant areas are found, they need to be repaired, such as re stamping, polishing, etc., until the quality of the motor shaft meets the qualified standards.
