Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering, and in particular to a material strength testing machine for building bridge welding engineering. Background Art

[0002] In bridge engineering, testing machines are needed to test the yield strength, tensile strength, impact toughness, etc. of steel used in bridge construction. It is an instrument that verifies the quality or performance of a product or material according to design requirements before it is put into use. Testing machines are mainly used to measure the physical properties of materials or products, such as the yield strength, tensile strength, and impact toughness of steel. They have two main loading methods, namely tension and compression, and can perform bending, shearing, and other functions by adding accessories. However, when traditional testing machines are used for impact strength tests of materials in building bridge welding projects, when the material is impacted and bent by the testing machine, after the punch head of the testing machine is reset, if the material is elastic, it will reset and bounce back after losing the extrusion force of the punch head, causing the material to detach from the punching machine, which is dangerous.

[0003] In response to the above problems, the prior art patent publication number CN212693500U discloses a material strength testing machine for building bridge welding projects. The push rod first contacts the material, causing the push rod to slide into the sleeve to squeeze the spring, and then the punch head starts to impact the material. After the material bends, the elastic force of the spring pushes the push rod to always contact the material. After the experiment is completed, the punch head is moved up and reset by the electric push rod. At this time, the sleeve moves up, and the push rod contacts the bent material through the spring, causing the elastic bent material to slowly recover its deformation until the push rod is separated from the material. The material is always contacted by the push rod and slowly recovers, preventing the bent material from suddenly bouncing up when the punch head loses the squeeze, thereby improving safety.

[0004] However, in the above method, the bolt needs to be manually tightened to adjust the distance between the two push rods, resulting in slow adjustment efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a material strength testing machine for building bridge welding engineering, aiming to solve the technical problem in the prior art that the distance between two push rods needs to be adjusted manually by screwing bolts, resulting in slow adjustment efficiency.

[0006] To achieve the above-mentioned purpose, the present invention adopts a material strength testing machine for building bridge welding engineering, including a body, a placement piece, a cylinder, two groups of protective components and an adjusting mechanism, the placement piece is arranged on the body, the adjusting mechanism includes a punching head, a bracket, a mounting plate, a first motor, a fixed block, two connecting blocks and two sliding blocks, the cylinder is installed on the body, the output end of the cylinder is fixedly connected to the bracket, the bracket is provided with two slide grooves, the mounting plate is fixedly connected to the bracket, the first motor is installed on the mounting plate, the two sliding blocks are respectively slidably connected to the corresponding slide grooves, the output end of the first motor is fixedly connected to the fixing block, one end of the two connecting blocks are hinged to the fixing block, the other ends of the two connecting blocks are respectively hinged to the corresponding sliders, the two groups of protective components are respectively arranged on the corresponding sliders, and the punching head is arranged on the bracket.

The two sliders drive the two groups of the protective components to move, so as to adjust the distance between the two groups of the protective components. Then the cylinder is started, and the cylinder drives the bracket to move downward. The protective component first contacts the material, and then the punch head starts to impact the material. At this time, the protective component always resists the material. After the experiment is completed, the cylinder drives the bracket to move upward.

In this way, the distance between the two groups of the protective components can be more conveniently adjusted, and the adjustment efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
