Male die lubricating structure based on self-oil-absorption metal and male die lubricating method

Abstract

The invention discloses a male die lubricating structure based on self-oil-absorption metal. The male die lubricating structure comprises a male die (1) and an upper die seat (2), the top surface of the male die (1) is provided with a strip-shaped slot (5) and a T-shaped slot (6), the strip-shaped slot (5) is internally provided with the self-oil-absorption metal (7), and a longitudinal slot body of the T-shaped slot (6) is internally provided with a cushion block (8); and the arc face of an arc-shaped slot (9) is provided with a small hole (10) penetrating through the self-oil-absorption metal (7), a compression spring (11) is arranged between the other side of the cushion block (8) and a transverse slot body of the T-shaped slot (6) in an abutted and pressed manner, and the arc-shaped slot (9) in the cushion block (8) abuts against a guide pillar (4) under the action of the compression spring (11). The invention furthermore discloses a male die lubricating method. The male die lubricating structure and the male die lubricating method have the advantages that consumption of lubricating oil is reduced, the lubricating oil does not need to be added manually, and the service life of the male die is prolonged.

Description

technical field [0001] The invention relates to the technical field of punch self-lubricating structures, in particular to a punch lubricating structure based on self-absorbing oil metal and a method thereof. Background technique [0002] At present, with the continuous development of the automobile and electronics industries, molds are required for bending, blanking, and hole forming of products. The molds include upper mold base, lower mold base, upper mold base, lower mold base, concave mold and convex The upper mold base is installed under the upper mold base, the punch is installed under the upper mold base, the lower mold base is installed above the lower mold base, and the die base is installed above the lower mold base, wherein the upper mold base and the punch are connected by screws , A guide column is also arranged between the upper mold base and the punch, the lower end of the guide column is fixed on the lower mold base, and the upper mold base can move up and d...

Problems solved by technology

However, the lubricating oil will move in all directions, and the lubricating oil often flows out from the gap between the upper die base and the punch, which not only affects the surrounding working environment, but also causes a waste of lubricating oil

When the lubricating oil is insufficient, it is necessary to remove the screw to separate the upper mold base from the punch, and then add new lubricating oil. This operation undoubtedly increases the labor intensity of the workers and the efficiency is also very low.
