Automobile tray bearing nut locking gasket blanking-molding-punching composite die and process thereof

Abstract

The invention discloses an automobile tray bearing nut locking gasket blanking-molding-punching composite die. The automobile tray bearing nut locking gasket blanking-molding-punching composite die comprises an upper die and a lower die, wherein the upper die comprises a die handle, an upper template, an upper base plate, an upper fixing plate and an upper discharging plate which are tightly connected in sequence from top to bottom; a blanking-molding-punching punch-die is arranged inside the upper fixing plate; the lower die comprises a blanking female die, a punching male die outer fixing plate, a lower base plate and a lower template which are tightly connected in sequence from top to bottom; a molding female die is arranged in the middle of the blanking female die; a punching male die inner fixing plate is arranged in the middle of the punching male die outer fixing plate; a punching male die is arranged in the middle of the punching male die inner fixing plate; the blanking-molding-punching punch-die, the molding female die and the punching male die form a molding die cavity for workpieces. The molding male die and the punching female die are compounded integrally, so that molding and punching are realized during blanking of blanks, the blank molding and punching processes are stable, and regular appearances and stable strength performance of bearing nut locking gaskets are ensured.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and in particular relates to an automobile tray-type bearing nut lock washer blanking forming punching composite mold and its technology. Background technique [0002] The bearing nut lock washer is installed on the car rear axle half shaft with brake assembly, its main function is to flatten the contact surface between the bearing nut and the half shaft bearing and to compress the half shaft bearing and prevent it from slipping when the bearing nut is installed phenomenon, so as to ensure that the car's rear axle shaft is installed on the brake assembly smoothly and firmly. [0003] The traditional production method of the bearing nut lock washer is divided into four processes. Firstly, the single-point shearing machine is used to implement the first step of the material processing, and then the single-point open steam press is used to implement the second step of the blanking proc...
