Novel punching head machine for producing steel pipes

Abstract

The invention discloses a novel punching head machine for producing steel pipes, which comprises a frame, a big gear, a small gear, a big belt wheel coaxially mounted with the small gear, a small belt wheel connected with the big belt wheel through a belt, a motor, an eccentric wheel mounted at a same transmission shaft with the big gear, a rocker mechanism, a guide rod mechanism, a drive head die connected with the guide rod mechanism and a connecting rod. By utilizing the working principle of a lever, the motor is used for driving the belt wheels, the gears and the eccentric wheel to rotate; and the rocker mechanism is driven to do swing motion through the eccentric role of the eccentric wheel, thereby further drawing the guide rod mechanism with a guide rail to do up and down motion, enabling the drive head die connected with the guide rod mechanism to do reciprocating motion and completing the process step of a drive head. The structure is simple, the use is reliable, the service life is long, the problem that parts on an original punching machine tool are often damaged is fundamentally solved, not only the production efficiency is improved, but also the safety in production is improved.

Description

technical field [0001] The invention relates to a punching machine, in particular to a new type of punching machine for producing steel pipes, especially suitable for the production of seamless steel pipes. Background technique [0002] Seamless steel pipe is a round, square or rectangular steel material with a hollow section and no joints around it. It is made of a steel ingot or a solid tube blank through perforation to make a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. Due to the different manufacturing processes of seamless steel pipes, they are divided into two types: hot-rolled and cold-drawn seamless steel pipes. Cold-drawn tubes are divided into two types: round tubes and special-shaped tubes. The production process route of cold drawn seamless steel pipe includes: round tube billet, heating, perforation, heading, annealing, pickling, oiling, multi-pass cold drawing, billet tube, heat treatment, straightening, hydraulic test, etc. The realizatio...

AI Technical Summary

Problems solved by technology

In the past, heading was often carried out on a punching machine. During the process of heading, due to factors such as impact force and self-weight, the parts of the punching machine were often damaged, which not only affected production, but also caused low production safety.
