Welded steel plate performance detection device and method

Abstract

The invention relates to a welded steel plate performance detection device comprising a work table, bearing devices, extrusion detection devices and a portal frame. The bearing devices are installed on the upper end face of the work table in a sliding fit and bilateral symmetry manner. The extrusion detection devices are arranged above the bearing devices in a front-back symmetry manner and are connected with the lower end of the portal frame in a sliding fit manner. The portal frame is installed on the work table. By means of the welded steel plate performance detection device and a welded steel plate performance detection method, outer extrusion and inner extrusion performance detection is conducted on welded steel plates through the extrusion detection device in the performance detection process, the welded steel plates are clamped through the bearing devices, and meanwhile a limiting effect on the welded steel plates is also achieved through the bearing devices.

Description

technical field [0001] The invention relates to the field of steel structure quality testing equipment, in particular to a performance testing device and method for welded steel plates. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology that combines metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. Welding has the advantages of good connection performance, good integrity, and wide adaptability. The completed steel plate will not be put into use immediately, and the welded steel plate is usually subjected to performance testing such as face bending and back bending, but the following problems may occur during the performance testing process of the welded steel plate: [0003] (1) Usually, when the external extrusion and internal extrusion inspection are performed on the welded steel plate, the welded steel plate has no clamping and limiting device, a...

AI Technical Summary

Problems solved by technology

[0003] (1) Usually, when the external extrusion and internal extrusion inspection are performed on the welded steel plate, the welded steel plate has no clamping and limiting device, and the welded steel plate is prone to deviation, causing the extrusion position to deviate, and the welded steel plate is easy to appear. Abnormal bending, and the pressure contact area on the welded steel plate is too large, which increases the probability of deformation of the welded steel plate;

[0004] (2) When performing internal extrusion, external extrusion, stretching and other performance tests on welded steel plates, equipment corresponding to each performance is usually used for testing, which complicates the working steps and wastes resources. At the same time, the performance testing of welded steel plates The equipment is usually only suitable for one structural type of welded steel plate, the utilization rate of the equipment is low, and it is necessary to manufacture specific testing equipment, which increases the production cost
