Description

Technical Field

[0001] The utility model relates to the technical field of strength detection, in particular to a strength detection device. Background Art

[0002] Cemented carbide is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Cemented carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drill bits, boring tools, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult-to-process materials. In the processing of some metal parts, some parts have strength testing requirements.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing strength detection device requires two sets of independent detection devices to test the tensile strength and bending strength of some metal parts, and the cost of manufacturing and subsequent maintenance is high. In addition, the parts need to be manually transferred and repositioned for strength testing, and the process is cumbersome and urgently needs to be improved. Therefore, we propose a strength detection device. Utility Model Content

[0006] A tension sensor is fixedly installed at the bottom of the transmission shaft of the hydraulic cylinder, and a pressure sensor is fixedly installed on the inner wall of the bottom of the frame. The tension sensor and the pressure sensor are respectively fixedly connected to the gantry on the same side;

[0007] A limit block is placed inside the gantry, a limit slot is provided inside the limit block, screws are screwed through screw holes on both sides of the limit block, an arc plate is placed inside the screw, and an anti-skid pad is fixedly installed inside the arc plate, and the inner end of the screw is rotatably connected to the arc plate through a bearing;

[0008] The limit block is fixedly provided with rotating rods on both the front and rear sides, and the rotating rods are movable and penetrate the side walls of the gantry;

[0009] Guide rods are fixedly installed on both sides of the arc-shaped plate, and the guide rods are movably inserted into guide grooves preset on the inner wall of the limit block;

During the use of the strength detection device, the two ends of the metal part can be respectively placed in the limit grooves, and then the screw rod is rotated to clamp the arc plate in position. During this period, the transmission shaft of the hydraulic cylinder can be contracted, and the part is subjected to a pulling force. Conversely, the transmission shaft of the hydraulic cylinder moves downward and the part is compressed. If bending deformation occurs, the rotating rod rotates adaptively, which can realize tensile strength detection and pressure bending strength test on the part. Compared with the existing design of two independent detection mechanisms, the cost of construction and subsequent maintenance costs are reduced, and frequent transfer tests of parts can be avoided.

[0011] As an optional scheme of the technical solution of the present application, a group of the limit blocks are fixedly installed with a convex strip on the front side, and another group of the limit blocks are fixedly installed with a ranging sensor on the top of the front side.
