Punching machine

Abstract

The invention discloses a punching machine. The punching machine comprises a frame; the frame is provided with a lifting cylinder and a lower base plate; the lifting cylinder is provided with an upperbase plate; a concave mold mounting plate is arranged on the bottom side of the upper base plate; a concave mold insert is arranged on the bottom side of the concave mold mounting plate; a convex mold mounting plate is arranged on the top side of the lower base plate; the top surface of the convex mold mounting plate is a support surface; a convex mold insert is arranged on the edge side of the support surface; multiple guide columns are arranged on the top side of the lower base plate; multiple first limiting through holes are formed in the upper base plate; first springs are arranged on theouter sides of the guide columns; a pressing plate is arranged on the bottom side of the concave mold mounting plate; limiting columns are arranged on the top surface of the pressing plate; second limiting through holes are formed in the concave mold mounting plate; blind holes are formed in the bottom surface of the upper base plate; the limiting columns penetrate through the second limiting through holes in sequence, and extend into the blind holes; limiting shaft shoulders are arranged at the top ends of the limiting columns; and second springs are arranged in the blind holes. The punchingmachine is higher in operation stability, can prolong the service life of a machine body, and reduces the energy consumption during working.

Description

technical field [0001] The invention relates to a stamping tool, in particular to a stamping machine. Background technique [0002] The vibrations produced by stamping machines on the market every time they are used are not only noisy, but also consume a lot of wear and tear on the mold and the stamping machine, and when the stamping module is under too much force, it is prone to damage, which will reduce the stamping module. The service life and the reset of the stamping module after stamping also need to be realized completely by the drive device, and the energy consumption is difficult to reduce. In addition, when the required materials are separated from the material sheet, the stress at the corners of the product is relatively concentrated, and the corners of the product are prone to cracking when the product is produced.

[0002] The vibrations produced by stamping machines on the market every time they are used are not only noisy, but also consume a lot of wear and tear on the mold and the stamping machine, and when the stamping module is under too much force, it is prone to damage, which will reduce the stamping module. The service life, the reset of the stamping module after stamping also needs to be realized completely by the drive device, and the energy consumption is difficult to reduce

In addition, when the required materials are separated from the material sheet, the stress at the corners of the product is relatively concentrated, and the corners of the product are prone to cracking when the product is produced. The traditional method increases the rounding of the corners, but the material used more, which increases the production cost and reduces the economic benefit
