Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die structure. Background Art

[0002] Stamping dies are a kind of process equipment that processes materials into workpieces or semi-finished products during stamping. They are the main process equipment for industrial production. Stamping dies can be used to produce parts using rolled steel plates or steel strips produced in large quantities by metallurgical plants as blanks, and no heating is required during production. They have the advantages of high production efficiency, good quality, light weight and low cost. Some stamping products require an arc concentricity of 0.1, so the stamping process of this product must be to perform punching on the arc after blanking is completed. The normal mold opening idea is to use a side-cut mold structure, but because the inner opening distance of the arc of this product is only 21, and the thickness of the product is 2mm, the side-cut mold faces problems such as insufficient blade strength and the inability to discharge waste smoothly. As a result, this type of product cannot use a side-cut mold structure, and the existing stamping equipment cannot meet different stamping requirements for stamping operations, which has limitations. Utility Model Content

[0003] The utility model aims to provide a stamping die structure, which first separates the arc waste at the upper half of the product, and then the waste continues to go down with the punch, and then the lower half of the arc of the product is punched and separated.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a stamping die structure, including an upper die seat, a lower die seat is arranged directly below the upper die seat, an upper pad is arranged at the bottom center of the upper die seat, an upper fixing plate is arranged at the bottom center of the upper pad, a punch is embedded on the inner side of the upper fixing plate, screw grooves are arranged between the upper die seat, the upper pad, the upper fixing plate and the punch and are fixed with screws, a lower fixing plate is fixed with screws at the top center of the lower die seat, spring holes are symmetrically arranged on the opposite sides of the upper fixing plate and the lower fixing plate, and reset springs are arranged in the spring holes, and the upper fixing plate The upper pressing plate is fixed with equal-height screws at the bottom, and the lower punch is fixed with equal-height screws on the top of the lower fixed plate. An inner guide column is fixedly connected to the left side of the top of the lower fixed plate, and an inner guide sleeve is slidably mounted on the inner guide column. The inner guide sleeve is upwardly engaged and fixed with the lower pressing plate. A limiting block is arranged on the outer side of the inner guide column, and the top of the limiting block extends outward from the top outer side of the lower fixed plate and is fixedly connected thereto, which can meet the stamping requirements of some products and meet the mold strength for smooth mass production. For some products, there is no need to cut the upper and lower arcs or holes on the side, and the waste can be directly flushed down at one time to avoid the problem of subsequent waste clogging and inability to be discharged smoothly.

[0005] According to the described stamping die structure, outer guide sleeves are symmetrically arranged at the bottom of the upper die seat, and the outer guide sleeves are upwardly penetrated through the top of the upper die seat and are fixedly connected thereto, and outer guide pillars are slidably cooperated on the inner side of the outer guide sleeves, and the bottoms of the outer guide pillars are extended into the inner wall of the lower die seat and are fixedly connected thereto.

[0006] According to the stamping die structure, a top annular array of the lower fixed plate is provided with balancing blocks.

[0007] According to the stamping die structure, a die sleeve is embedded and fixed at the top center of the lower fixed plate.

[0008] According to the stamping die structure, the top outer edges of the outer guide pillar and the inner guide pillar are both rounded.

[0009] According to the stamping die structure, the inner sides of the outer guide sleeve and the inner guide sleeve are both adhered and coated with a layer of lubricating film.

[0010] The above scheme has the following beneficial effects:

[0011] The utility model can meet the stamping requirements of some products and meet the mold strength for smooth mass production. For some products, there is no need to cut the upper and lower arcs or holes, and the waste can be directly flushed out at one time, avoiding the problem of subsequent waste clogging and inability to be discharged smoothly.
