Clutch cap forming process and forming equipment thereof

Abstract

The invention discloses a clutch cap forming process. The clutch cap forming process is characterized by including the following steps of (a) blanking, (b) pressing a middle boss, (c) bending four rotating lugs, (d) angle R shaping of two corresponding rotating lugs, (e) angle R shaping of the other two rotating lugs, (f) shaping flatness, and (g) punching. The invention further discloses clutch cap forming equipment which comprises a blanking die, a stretching die, a bending die, a first shaping die, a second shaping die and a punching die. According to the clutch cap forming process and the forming equipment thereof, the mode that pulling is carried out first and then folding is carried out is adopted, the thickness of a clutch can reach 6.35 mm, and the obtained bearing force of the clutch can reach 100000 newtons; meanwhile, a bending mode with an angle R is adopted, the probability that materials break during bending is reduced, and the bending success rate reaches 99.3%; angle R shaping of the rotating lugs is carried out twice, the angle R is eliminated, an assembling hole is convenient to form, and the best shaping effect is achieved; a flatness shaping procedure is arranged, accuracy of the formed hole is guaranteed, and meanwhile, a cap of the clutch and the clutch are accurately assembled.

Description

technical field [0001] The invention relates to a stamping part forming process and forming equipment, in particular to a clutch cover forming process and forming equipment. Background technique [0002] Automobile clutches are generally formed by integral casting, that is, the smelted liquid metal is injected into the pre-prepared mold by pouring, injection, suction or other casting methods, and the finished product is obtained after cooling, sanding, cleaning and post-processing. [0003] The disadvantages of castings are that the material has low bearing capacity and poor toughness. In order to achieve the target bearing capacity, the general method is to increase the thickness, and the increase in thickness will lead to an increase in the volume and weight of the part. [0004] The clutch diameter of heavy-duty trucks reaches about 500mm, so the requirements for its load-carrying capacity and material toughness are very high. Ordinary integral casting is not suitable for...

AI Technical Summary

Problems solved by technology

[0006] However, in the actual research and development process, it was found that the following problems occurred when the heavy-duty clutch was formed by stamping: a. In general stamping, the thickness of the clutch cover can only be kept below 5mm, while the heavy-duty clutch has high requirements for bearing capacity. The clutch cover cannot meet the load-bearing requirements; b. During the forming process of the clutch cover, because the turning lugs on the periphery of the clutch cover need to be bent at 90 degrees, material fractures often occur during bending; c. The assembly of the clutch cover and the clutch cover body Poor flatness, not tight assembly
