Forging claw pole process and equipment selection
2017-11-15 17:32:53
Claw pole is a key part of the AC motor is one of the core components of power generation, and forging claw pole is also an essential part of every car, claw pole forgings occupies an important position and broad prospects in the industrial field. The quality of forging claw pole accuracy directly affects the level of productivity. Therefore, to determine the appropriate forging process and equipment models directly related to the claw pole quality.
AC claw pole paw part of the cloth in a circle, 6 claws into an approximate table, the outer circumference of the vertical perpendicular to the bottom surface of the inner circumference of a certain gradient, and the round table are not symmetrical around. Claw pole process design is the first step in hot forging design, his good and bad are directly related to the quality of parts, cost, productivity and mold life.
1. Forging claw pole drawing
Determine the location of the parting surface; allowances and tolerances; fillet radius; forging slope; punching with skin
2. Cutting equipment selection and bar material
Taking into account the accuracy requirements of the blank and the advantages and disadvantages of the shearing method and the selected raw materials, cutting sawing method selected, the method of high productivity, high degree of automation, suitable for mass production.
3. Die forging equipment selection
Based on the characteristics of claw pole forming and its technical requirements, the air hammer, hydraulic closed die forging hammer, CNC hydraulic closed die forging hammer, electric screw press, etc. can be selected for the upsetting equipment (according to the investment situation reasonably arranged); Forming equipment recommended electric screw press (Anyang Forging Press Company forging precision forging equipment); trimming equipment optional trimming presses.
4. Blank shape and size selection
The shape and size of the blank have a great influence on the filling performance of the forging claw pole and the service life of the die. According to the shape characteristics of the claw pole forging, a forging drawing is drawn. The forging is divided into several parts to calculate the final volume of the forging claw pole.
To sum up, in general, the selection of a reasonable die forging process is the key of the forging process design. The choice should be based on specific production conditions, and consider both technical and economic issues. Synthetic current claw pole development status, its production methods are the following: casting, forging, stamping, cold forging, cold forging combination. Comprehensive consideration of the advantages and disadvantages of forging claw pole process at home and abroad, closed die forging process methods came into being, with specific steps: cutting blanking - heating - upsetting - forging - machining. This forging process significantly reduces the production steps, save time and effort, reduce costs, is a relatively mature method of manufacturing.
