Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.

[0011] Such as figure 1 As shown, a bending stamping die provided by the present invention includes an upper cover plate 1, an upper mold base 3, an upper backing plate 4, a punch fixing plate 5, and upper and other height limit blocks 6 connected in sequence; The positioning block 7, the lower template 8, the lower backing plate 9, and the lower mold base 10 are connected in sequence, and the lower forming block 14 is provided in the middle of the lower equal-height limiting block 7, which is consistent with the shape of the part, and the positioning pin is arranged in the middle of the lower forming block 14. 13. The stripping sleeve 11 runs through the middle of the upper backing plate 4 ...

Abstract

The invention discloses a bending stamping die, which comprises an upper cover plate, an upper die holder, an upper base plate, a punch fixed plate and an upper equal-altitude limit block which are connected sequentially and a lower equal-altitude limit block, a lower die plate, a lower base plate and a lower die holder which are connected sequentially, wherein a lower forming block is arranged on the middle part of the lower equal-altitude limit block; a positioning needle is arranged on the middle part of the lower forming block; a stripping sleeve passes through the middle parts of the upper base plate and the punch fixed plate; the stripping sleeve is connected with a stripping block arranged on the middle part of the upper equal-altitude limit block; and a forming punch corresponding to the lower forming block is arranged on the punch fixed block. The shape of a lower die is consistent with that of a part, a male die is subjected to resilience appropriately, and materials are pressed by a spring, so that the part is formed at one time. Therefore, out-of-tolerance caused by repeated bending is prevented, an error is reduced and labor and time are saved.

Description

technical field [0001] The invention relates to a bending stamping die. Background technique [0002] The status of the mold industry in the national economy is rising day by day. Mold is the basic process equipment for industrial production. In products such as electronics, automobiles, motors, electrical appliances, instruments, home appliances and communications, 60% to 80% of the parts rely on molds Forming, the quality of the mold directly determines the quality of the product, therefore, the mold is called "the mother of all industries". The mold is also a "benefit amplifier". The value of the final product produced by the mold is often dozens or hundreds of times the value of the mold itself. [0003] At present, for parts with many bends, only one bend can be processed each time with a bending machine, and the cumulative tolerance will exceed the control range, and it is difficult to achieve the effect required by the design. Contents of the invention [0004] Pu...
