Problems solved by technology

The disadvantages of this kind of equipment are: 1. The equipment is huge, the structure is complex, the equipment cost is high, and it requires a large driving force, which greatly increases the manufacturing cost of the steel pipe; 2. The work efficiency is low, and only one stroke is effective for drawing steel pipes. The second pulling can only be done after the car returns

Abstract

A reciprocating steel pipe drawing machine is composed of machine frame, reducing dies and their supporters at both ends of machine frame, screw bolt between said reducing dies for drawing steel pipe and its driver, and steel pipe clamps installed to both ends of said screw bolt. It features its bidirectional drawing for high productivity.

Description

technical field [0001] The invention relates to a steel rolling equipment, in particular to a steel pipe pulling machine. Background technique [0002] Existing steel pipe extubation machine is mainly made up of extubation vehicle, and the crawler belt that drives extubation vehicle movement and extubation die, pulls pipe by extubation vehicle and completes extubation through extubation die. The disadvantages of this kind of equipment are: 1. The equipment is huge, the structure is complex, the equipment cost is high, and it requires a large driving force, which greatly increases the manufacturing cost of the steel pipe; The second pull can only be carried out after the car returns. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reciprocating steel pipe pulling machine which has a simple structure and can continuously pull steel pipes. [0004] In order to achieve the above object, the technical solution of ...
