Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

[0021] A production method of transmission parts, it comprises the following steps:

[0022] 1) 40T punching machine is used for blanking. The diameter and length of the blanking are calculated according to the methods known in the industry, that is, the weight of the blanking is equal to the weight of the finished product plus the weight of the machining allowance, and then a round bar with a small diameter is selected Steel, and then calculate the blanking diameter according to the volume to be 28.3 -0.1 0 mm, the length is 51±0.3mm;

[0023] 2) Chamfer the blanking material on the instrument lathe with a flat head, and the length of the blanking material after the flat head is 50.2 -0.2 0 mm;

[0024] 3) Blanking the flat head and the outer circle of the car on the instrument lathe to make the blank material of the press mold in step 5). The...

Abstract

The invention discloses a method for producing a transmission part, which comprises the steps of: 1) adopting a punch press for blanking; 2) performing flat head chamfering on a blanked material; 3) producing the blanked material into a blank which satisfies a pressing machine mold in step 5); 4) performing annealing treatment on the blank; 5) performing cold extrusion thickening on the blank; 6) punching a central hole on the thickened blank, chamfering after the reaming, and then turning an external circle; 7) performing cold extrusion curve molding on the blank; 8) performing cold extrusion spline treatment on a workpiece; 9) then performing plane turning and chamfering on the workpiece; 10) then removing an overlong part of a small diameter end of the workpiece through the turning, rough turning a plane, and then chamfering; 11) turning an external circle of a large diameter end of the workpiece into a needed shape, slotting the position, which is near the end surface, of an external circle surface of the small diameter end, and chamfering a central hole of the small diameter end at the same time; and 12) performing flat head chamfering and inner hole reaming on the treated workpiece to obtain a finished product. Compared with the prior art, the method saves the time of working procedures, saves raw materials, and has higher rate of finished products and lower cost.

Description

[0001] Method field: [0002] The invention belongs to the field of vehicle accessories, in particular to a production method of a transmission part. Background technique: [0003] The steps of the production method of the transmission part in the prior art are usually: firstly, the blank is formed by a common casting process; finally, the casting is turned into shape. However, since the blank is an ordinary casting, the material structure and crystal density are loose, which easily affects the quality of the product, so the yield is low and the cost is high. Invention content: [0004] Aiming at the above problems, the present invention provides a production method of transmission parts with higher yield and lower cost. [0005] The technical solution used by the present invention to solve the above problems is to provide a production method of transmission parts, which includes the following steps; [0006] 1) Use a punching machine to blank, and the weight of the blank ...
