Auto rear door lock reinforcement plate stamping die

Abstract

The invention discloses a stamping die of an automobile back door lock reinforcing plate, relating to the technical field of manufacturing of stamping dies. The stamping die comprises an upper die seat and a lower die seat, wherein the lower end of the upper die seat is sequentially provided with an upper clamping plate, an upper template and a molding convex die; edge overturning stamping heads are arranged on the two sides of the molding convex die and penetrate through the upper template and the upper clamping plate to be connected with the upper die seat; the upper clamping plate is provided with a plurality of loading and unloading springs; a plurality of loading and unloading bolts connected with the upper template are hung on the upper die seat; a lower base plate and a molding concave die are sequentially arranged at the upper end of the lower die seat; lower templates are arranged on the two sides of the molding concave die; edge overturning grooves corresponding to the edge overturning stamping heads are formed between the lower template and the molding concave die; a plurality of loading and unloading springs are arranged on the lower base plate; the lower die seat is provided with a plurality of loading and unloading bolts connected with the molding concave die. Compared with the prior art, edge overturning can be carried out when a workpiece is stamped and molded and all machining procedures of the automobile back door lock reinforcing plate are finished; the workpiece does not need to be repositioned and is accurate in positioning, and the product quality is stable.

Description

technical field [0001] The invention relates to the technical field of stamping die manufacturing, in particular to a stamping die used for pressing and flanging a rear door lock reinforcement plate of an automobile. Background technique [0002] Such as figure 1 The rear door lock reinforcement plate shown in the car includes a reinforcement plate body 101 with a bent connecting portion 102 protruding upward in the middle. The opposite sides of the reinforcement plate body 101 are provided with sloping plates 104 inclined downwards. The slant plate 104 is connected with a support plate 104 protruding outwards. On the other two sides of the reinforcing plate body 101, there are upwardly tilted seesaws 103. The processing of the automotive rear door lock reinforcing plate requires pressing and flanging. Existing stamping dies for reinforcement plates of automobile rear door locks can only be processed in a single process. First, the workpiece of the reinforcement plate is st...
