Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] see figure 1 , a stamping die described in a preferred embodiment of the present invention includes an upper mold base 1 and a lower mold base 2, the upper mold base 1 can move relative to the lower mold base 2 and press the lower mold base 2, and the upper mold base 1 A punch 3 is arranged on the top, and an upper wear-resistant convex edge 31 is arranged on the bottom of the punch 3. The upper wear-resistant convex edge 31 is made of ceramic material. Since the punch 3 needs to be pressed down many times in industrial production, it is easy to be damaged. After the mold 3 is provided with an upper wear-resistant convex edge 31, the loss is reduced due to the good...

Abstract

The invention relates to a stamping die. The stamping die comprises an upper die holder (1) and a lower die holder (2) which are oppositely arranged, wherein a male die (3) is arranged on the upper die holder (1); a female die (4) is arranged on the lower die holder (2); a hollow space (5) is formed in the male die (3); a pushing device (51) is arranged in the hollow space (5) and connected with a pressing plate (53) via a push bar (52) arranged on the pushing device (51); the pressing plate (53) is used for edge pressing of stamping formed parts; and the pushing device (51) pushes the pressing plate (53) to change the distance between the pressing plate (53) and the bottom edge of the male die (3). According to the stamping die, the pressing plate is pushed by a hydraulic oil cylinder, so that the position of the pressing plate on the male die can be changed, further, the distance between the pressing plate and a lower die can be changed after an upper die is pressed down, and accordingly, the formed parts with different thicknesses can be pressed down.

Description

technical field [0001] The invention relates to a die, in particular to a metal stamping die. Background technique [0002] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The application fields of sheet metal parts are extremely wide, and they penetrate into all aspects of the manufacturing industry. Sheet metal forming is mainly realized by stamping dies. Using the stamping process, it has a series of advantages such as high precision, high efficiency, good quality, cost saving, material and energy saving. [0003] For stamping dies, it is generally required to have good rigidity and impact resistance. Under repeated impacts, the dies are not easy to crack or deform. And the existing punching dies can only punch a single die, and cannot be adjusted to punch dies with different thicknesses. Contents of the invention [0004] In order to solve the above technical problems, the object of the ...
