Tensile resistance testing device for copper pipe

Abstract

The invention discloses a tensile resistance testing device for a copper pipe. The device comprises a workbench. Mounting plates are welded to the middle parts of the two ends of the workbench; fixation blocks are welded to the middle of one end of the mounting plate at equal intervals; connection blocks are arranged at edges of the ends of the fixation blocks; first screw rods are in threaded connection with the insides of the connecting blocks; buffer blocks are connected to the middle parts of ends of the first screw rods; and clamping blocks are connected to the middle parts of parts of the buffer blocks. According to the invention, the testing device has a scientific and reasonable structure and is used safely and conveniently. With the fixation blocks, the connection blocks, the first screw rods, the buffer blocks, the clamping blocks, lower clamping blocks, second screw rods, and upper clamping blocks, the two ends of a copper pipe can be fixedly clamped; after combination of the clamping blocks, the upper clamping blocks and the lower clamping blocks, tensile testing can be carried out on the copper pipe and the clamping stresses on the copper pipe become uniform; and the clamping force can be adjusted based on copper pipes with different diameters, so that the stability of clamping the copper pipe by the device is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tensile testing device for copper pipes. Background technique [0002] Copper tube, also known as copper tube, is a kind of non-ferrous metal tube. It is a pressed and drawn seamless tube. Copper tube has good electrical conductivity and thermal conductivity. It is the main material of conductive accessories and heat dissipation accessories of electronic products. , is also commonly used in tap water pipes, heating and cooling pipes. As an installation pipe, it has the advantages of hard texture, not easy to corrode, high temperature resistance, high pressure resistance, etc. It can be used in different environments. Copper pipes combine the advantages of metal and non-metal pipes. , is unique in the hot and cold water system, is the best connecting pipe, copper pipe is fire-resistant and heat-resistant, it can still maintain its shape and strength at high tempera...

Problems solved by technology

[0005] The present invention provides a tensile test device for copper tubes, which can effectively solve the problems raised in the above background technology. However, the current tensile test devices for copper tube products are easily affected by the diameter of copper tubes. One copper tube can be accurately tested, and the tensile test of copper tube products with different diameters cannot be applied. If the different calibers of copper tubes are used forcibly and the copper tubes cannot be fixed and clamped, the practicability is low, making copper tubes of different diameters The problem that the product needs to use special equipment for copper pipe tensile inspection
