Abstract

The invention discloses a pipe blanking die. The pipe blanking die comprises an upper die and a lower die, wherein the upper die and the lower die are connected through a guide column guide sleeve (7). The pipe blanking die is characterized in that the upper die comprises an upper template (1), an upper pressing die (3) is installed on the upper template through an upper pressing board (2), and the upper pressing die is provided with an upper groove (31) used for clamping pipes; the lower die comprises a lower template (6), a lower pressing die (4) is installed on the lower template through a lower pressing board (5), the lower pressing die is provided with a lower groove (41) used for clamping the pipes, an elastic body (9) is arranged at the lower portion of the lower pressing die (4), and the side edge of the lower pressing die is provided with a cutting edge (8) used for blanking the pipes. The pipe blanking die of the technical scheme is high in blanking speed and higher in working efficiency compared with an abrasive cutting mode; as the elastic body is arranged at the lower portion of the lower pressing die, the buffer effect is achieved when the upper die tightly presses the pipes, and the pipes are blanked and cut under the action of an upper female die and the cutting edge and are prevented from being pressed flat.

Description

technical field [0001] The invention relates to a die, in particular to a pipe blanking die. Background technique [0002] In actual production, the pipes are often cut to obtain pipes of different lengths and sizes. The pipe is a hollow profile, which is usually cut with a grinding wheel in actual production, which is inefficient, and the pipe will be flattened when punched with a die. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, to provide a pipe blanking die that avoids the pipe from being flattened and has high production efficiency [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A pipe blanking die, comprising an upper die and a lower die, the upper die and the lower die are connected through guide posts and guide sleeves, the upper die includes an upper template, and an upper die is installed on the upper die through an upper pr...
