Abstract

The invention discloses a stretching straightening device for metal pipe machining, and relates to the technical field of pipe machining. The device comprises a supporting plate, wherein the two endsof the supporting plate are in sliding fit with stretching frames respectively; one end of the supporting plate is fixedly connected with a first air cylinder; the end of the first air cylinder is fixedly connected with one stretching frame; a hanging frame is hinged to the side surface of the bottom of the other stretching frame; and one end of the hanging frame is in suspended connection with the supporting plate. Two movable frames are in sliding fit with the surface of the supporting plate. Brackets are in sliding fit with the inner sides of the movable frames, and adjusting screw rods inthreaded fit with the tops of the movable frames are rotationally connected with the top ends of the brackets. The brackets slide in an ascending and descending mode through the two movable frames under the action of the adjusting screw rods, the two ends of a bent metal pipe can be aligned with the two stretching frames, and the stretching frames can conveniently and directly fix the bent metal pipe; expansion type clamping and fixing are carried out from the inner side of the metal pipe to the outside, so that the situation that the end of the metal pipe is flattened is avoided; and metal pipes with different calibers can be clamped, and the universality is high.

Description

technical field [0001] The invention belongs to the technical field of pipe processing, in particular to a stretching straightening device for metal pipe processing. Background technique [0002] Metal pipes, also known as steel pipes, are used to transport fluids and powdery solids, exchange heat, manufacture mechanical parts and containers, and are also an economical steel. The development of the chemical industry, as well as the drilling and transportation of oil and gas, have all vigorously promoted the development of the steel pipe industry in terms of variety, output and quality. Steel pipes can be divided into two categories according to production methods: seamless steel pipes and seamed steel pipes, which can be used in various industries for liquid pressure pipes, gas pipes, water pipes, gas pipes, heating pipes, electrical pipes, etc. [0003] Chinese patent CN204700089U (application number: CN201520409486.4) discloses "a hydraulic stretching straightening machin...
