Outer clamping head of square pipe tensile property detection equipment

Abstract

The invention provides an outer clamping head of square pipe tensile property detection equipment, and belongs to the technical field of detection, which solves the technical problems that the existing square pipe tensile property detection equipment is not suitable for clamping square pipes of different sizes and the like. The outer clamping head of the square pipe tensile property detection equipment comprises a clamping sleeve and four clamping blocks, wherein the clamping sleeve is sleeved at the outer side of the square pipe; the four clamping blocks are respectively positioned at the inner side of the clamping sleeve; a guide rod is fixedly arranged on each clamping block, and is inserted into the clamping sleeve; the center lines of the four guide rods are crossed on the center of the clamping sleeve; the clamping sleeve is also screwed with jacking bolts corresponding to the clamping blocks; the end of each jacking bolt is jacked against the corresponding clamping block, so asto enable the four clamping blocks to clamp the square pipe. The outer clamping head has the advantage that the outer sides of the square pipes of different sizes can be clamped.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a square tube tensile testing device, in particular to an outer chuck of the square tube tensile testing device. Background technique [0002] The tensile performance of the steel pipe is an important indicator for evaluating the performance of the steel pipe, so it is necessary to sample the tensile performance of the steel pipe before leaving the factory. The tensile performance of the steel pipe needs to be tested by tensile testing equipment. During the test, both ends of the steel pipe need to be clamped and fixed before the steel pipe is stretched. The current testing equipment is tested by stretching both ends of the steel pipe at the same time, which requires two sets of cylinders to provide tensile force. At the same time, the two sets of cylinders need to ensure that the provided force is the same, and the requirements for the cylinder are higher. , leading to higher cos...

AI Technical Summary

Problems solved by technology

The current testing equipment is tested by stretching both ends of the steel pipe at the same time, which requires two sets of cylinders to provide tensile force. At the same time, the two sets of cylinders need to ensure that the provided force is the same, and the requirements for the cylinder are higher. , leading to higher costs; in addition, the existing tensile testing equipment is mainly for round tubes, and it is necessary to provide a special square tube clamping assembly when testing the opposite tube. Prepare one-to-one corresponding clamping components for square tubes of different sizes, which further increases the cost
