Stamping Right Angle Bending Die for Computer Case Side Cover

Abstract

The invention discloses a right-angle bending die for stamping the side cover of a computer case. This right-angle bending die for stamping the side cover of a computer case includes a bottom plate, a lower mold base and an upper mold base are sequentially arranged above the base plate, and an upper backing plate, The punch fixing plate, the top plate and the lower backing plate, the punch fixing plate is provided with a punch; There are pressing nails passing through the punch, the upper backing plate and the upper die seat; elastic rubber is arranged between the bottom plate and the lower die seat. The present invention is simple in structure, reasonable in design and convenient in operation, which ensures the clamping accuracy of the upper and lower mold bases, and ensures the overall strength and rigidity of the mould. Debugging and trimming ensure the flatness and dimensional accuracy of the product.

Description

technical field [0001] The invention relates to the technical field of bending dies, in particular to a right-angle bending die for stamping computer case side covers that is widely used in the computer case side cover production industry. Background technique [0002] The side cover of the desktop computer case has a large size, complex structure, many forming processes, and high output requirements, which makes the mold design difficult, especially the 90° right-angle bending process of the side. Since the material thickness of the side cover of the desktop computer case is only 0.6mm, the gap between the bending punch and the die is 0.6mm. The structure of the traditional right-angle bending die is complex, and the guiding accuracy of the bending die with a small gap will affect the surface quality of the workpiece. Even damage the working surface of the punch and die. The asymmetric large-size bending workpiece obtained by the traditional right-angle bending die is pron...

[0002] The side cover of the desktop computer case has a large size, complex structure, many forming processes, and high output requirements, which makes the mold design difficult, especially the 90° right-angle bending process of the side

Since the material thickness of the side cover of the desktop computer case is only 0.6mm, the gap between the bending punch and the die is 0.6mm. The structure of the traditional right-angle bending die is complex, and the guiding accuracy of the bending die with a small gap will affect the surface quality of the workpiece. Even damage the working surfaces of the punch and die

The asymmetrical large-size bending workpiece obtained by the traditional right-angle bending die is prone to deviation of the blank, and the product failure rate is high. In addition to being not conducive to the debugging and repair of the mold, it also greatly increases the production cost.
