Punching die for truncated-cone-shaped tube

Abstract

The invention discloses a punching die for a truncated-cone-shaped tube. The punching die comprises an upper die seat, a male die, a lower die seat and a female die, wherein two compression bars are symmetrically connected to the left and right sides of the downside of the upper die seat, vertical sliding blocks are connected to the lower ends of the compression bars, the female die is connected to the upside of the lower die seat, supporting seats are respectively arranged at the left and right sides of the female die, the supporting seats are connected onto the lower die seat, the upper sides of the supporting seats are movably connected with horizontal sliding blocks, the punching male die is connected onto the horizontal sliding blocks and is horizontally arranged, supporting plates are arranged between the female die and the supporting seats, and springs are arranged between the supporting plates and the horizontal sliding blocks. The truncated-cone-shaped tube is accurate and convenient to locate, the degree of rotational symmetry of two holes is high, deformation cannot be caused, the quality of product is high, wasting is avoided, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a punching die for a truncated tube. Background technique [0002] Stamping is a pressure processing method that uses a stamping die installed on a press under normal temperature conditions to apply pressure to the raw material to separate or plastically deform the raw material to obtain the required parts. The punching die is to punch out the raw material. Molds of various types of holes, the raw materials can be plates, circular pipes, truncated circular pipes, etc. like Figure 4 Shown is a cross-sectional view of a truncated conical tube with two axially symmetrical through holes. Due to the large batch size, punching dies are used in production. When processing an ordinary punching die, the truncated conical tube is placed horizontally. Enter the punching die, and punch out the two holes when the upper and lower dies are pressed together. However, during the processing of...

Problems solved by technology

However, during the processing of this kind of punching die, the truncated conical tube is positioned by the upper and lower pressing plates, and the positioning of the truncated conical tube is not easy. If the upper and lower pressing plates are pressed too loosely, the positioning of the truncated conical tube is not accurate, and it is easy to cause the two holes to be out of alignment. Symmetrical; if the upper and lower plates are pressed too tightly, the truncated tube is easily deformed, seriously affecting product quality and causing waste
