Embodiment 1

[0067] Made as figure 1 , figure 2 , image 3 The schematic diagram of the processing process of the gear ring base shown in the figure is as follows: Figure 33 , the specific process steps refer to Figure 7-Figure 20 :

[0068] Process 1: punching and blanking.

[0069] Equipment: full hydraulic fine blanking press

[0070] Mold working drawing see Figure 7 , use the outer slider of the special press to drive the ring gear blank holder 12 to move down, press the material on the upper end surface of the die, and at the same time, the inner slide of the full hydraulic fine blanking press moves down quickly to drive the punch 11 of the mold to move down. The outer contour of the product is cut, and at the same time, the inner punch of the full hydraulic fine blanking press moves up quickly, driving the inner punch 17 upward, and under the action of the inner hole of the punch 11, the inner contour of the product is cut.

[0071] After the blanking is completed, the up...

Abstract

The invention discloses a method for manufacturing an alligatoring ring matrix with a novel structure, relating to the technical field of synchronizers alligatoring rings of automobile gearboxes and aiming at solving the technical problems that the conventional method for manufacturing the synchronizers alligatoring rings has complicated process, low production efficiency, low material utilizationrate, large amount of consumption of expensive nonferrous metals, extremely-high production cost, poor strength of large-diameter alligatoring rings and the like. The method for manufacturing the alligatoring ring matrix with the novel structure comprises the following steps: blanking: annealing, parkerising and saponifying; bending lug bosses: flanging to form an internal conical surface; finelypunching into a tooth shape: annealing, parkerising and saponifying; extruding a locking surface: finely shaping the tooth shaft of involute; fine correction; thermal treatment; shot blast treatment;and finely machining the internal conical surface. The invention is suitable for manufacturing alligatoring ring matrixes with novel structures of the automobile gearboxes.

Description

technical field [0001] The invention relates to the technical field of a gear ring of an automobile gearbox synchronizer, in particular to a method for manufacturing a base body of a gear ring with a new structure. Background technique [0002] At present, most of the synchronizer gear rings used in small and medium-sized automobile gearboxes are made of complex copper alloys through casting and forging. The surface is sprayed with molybdenum or friction material is attached to improve the friction coefficient and service life of the inner surface. The manufacturing process is very complicated, the production efficiency is low, the production cycle is long, the consumption of materials is large, and the utilization rate of materials is very low. The copper, nickel, cobalt and other non-ferrous metals consumed by the copper alloy gear ring are expensive. [0003] The powder metallurgy base gear ring is formed by powder metallurgy forming and sintering, and then cutting and a...
