Seamless steel pipe straightening equipment

Abstract

The invention provides seamless steel pipe straightening equipment. The seamless steel pipe straightening equipment comprises a receiving plate, a straightening plate, a pressing plate, a mounting plate and a first air cylinder. A first support and a second support are vertically arranged at the two ends of the receiving plate. The straightening plate is located above the receiving plate and parallel to the receiving plate, and the two ends of the straightening plate are connected with the first support and the second support correspondingly. Multiple mounting holes penetrating through the upper surface and the lower surface of the straightening plate are formed in the straightening plate, straightening dies are mounted in the mounting holes, and the straightening dies are provided with straightening holes penetrating through the upper surfaces and the lower surfaces of the straightening dies. The pressing plate is located above the straightening plate and parallel to the straightening plate, and the two ends of the pressing plate are connected with the first support and the second support in a sliding fit manner correspondingly. The mounting plate is located above the pressing plate, and the two ends of the mounting plate are connected with the first support and the second support correspondingly. The first air cylinder is mounted on the mounting plate, and the first air cylinder is connected with the pressing plate. The seamless steel pipe straightening equipment is simple in structure and convenient to operate, multiple steel pipes can be straightened simultaneously, the steel pipes with different sizes can be straightened, and the straightening precision is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe straightening, in particular to a seamless steel pipe straightening equipment. Background technique [0002] After cold deformation processing, the metal structure and crystal structure of seamless steel pipes change, and heat treatment such as high-temperature solid melting is required. The purpose is to improve the metal structure of seamless steel pipes through high-temperature heat treatment technology, and make the internal crystal structure re-ball to meet the requirements of subsequent processing. However, after high-temperature heat treatment, the seamless steel pipe will have the problem of bending deformation in the length direction, and must be straightened and finished to meet the straightness requirements of the finished product or subsequent processing. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present inventio...
