Stamping device for integrally forming round pipe

Abstract

The invention provides a stamping device for integrally forming a round pipe, and belongs to the technical field of machining. The device comprises a base panel, two positioning blocks, two rotating female dies, a pushing mechanism and a restoring mechanism, the two positioning blocks are arranged on the base panel, first notch grooves are formed in the opposite side faces of the two positioning blocks, and each first notch groove comprises a first vertical face, a first arc face and a first inclined face; a limiting plate is vertically arranged on the upper side edge of the first vertical face, the rotating female dies are rotationally arranged in the corresponding first notch grooves, extrusion grooves are formed in the opposite side faces of the two rotating female dies, and each extrusion groove comprises a second inclined face, a second arc face and a second vertical face; the pushing mechanism can press the steel plate placed between the two limiting plates into the two second arc faces, the steel plate is punched into a round pipe, and after the steel plate is pressed into the round pipe, the restoring mechanism can enable the two rotating female dies to rotate to the upper side face to be horizontal. A steel plate can be punched into a round pipe at a time, and operation is easy.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a stamping device for integrally forming round pipes. Background technique [0002] Stamping die is a special process equipment for processing metal or non-metal materials into parts or semi-finished products in cold stamping processing, called cold stamping die. [0003] Stamping is a pressure processing method that uses a die installed on a press to exert pressure on a material at room temperature to cause plastic deformation to obtain the required parts. [0004] In the existing round tube stamping forming technology, it is necessary to bend the steel plate multiple times, and then perform internal and external submerged arc welding to form a round tube before pressing it into a round tube. This process is complicated to operate, time-consuming and laborious; It is easy to deform the steel plate, resulting in uneven thickness of the round tube Contents of the in...
