Vehicle clutch cover pressing side cutting and center hole punching composite die

Abstract

The invention discloses a vehicle clutch cover pressing side cutting and center hole punching composite die which comprises an upper die frame plate, a lower die frame plate and a discharging plate. The lower end face of an upper die cushion plate is connected with a hole punching protruding die. A lower die cushion plate is provided with a hole punching concave die which is placed below the hole punching protruding die and is matched with the hole punching protruding die when the hole punching protruding die is pressed down. The discharging plate is connected to the hole punching protruding die in a sleeved mode. The discharging plate is connected with the upper die frame plate through a spring. A side cutting protruding die which is placed below the discharging plate and is matched with a side cutting concave die insert is connected to the outside of the hole punching concave die in a sleeved mode. The vehicle clutch cover pressing side cutting and center hole punching composite die has the advantages that the two procedures of cover side cutting and center hole punching are completed in a concentrating mode, so that a machining cycle is greatly shortened, production efficiency is improved, half-finished product turnover is lowered, and the labor intensity of workers is lowered; and the accuracy and the concentricity of products can be guaranteed, and then product quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile clutches, in particular to a composite mold for cutting edges and punching center holes of an automobile clutch gland. Background technique [0002] Stamping die is an indispensable process equipment for stamping production. The level of die design and manufacturing technology largely determines the quality, efficiency and development ability of new products. The original die has a single process, and the workpiece to be processed reaches The finished workpiece needs to go through several processes before it can be formed, which greatly wastes manpower and time. At the same time, it also needs a lot of space to turn around the semi-finished product, and the accuracy and concentricity requirements of the product cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compound mold for trimming and punching the center ...
