DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: See Figures 1 to 3The utility model provides a metal material mechanical hydraulic testing machine, including a machine base 1, on which a test platform 2 is fixedly arranged, and a hydraulic cylinder 3 is fixedly arranged just above the test platform 2. The machine base 1 includes a base 101, two support columns 102 fixedly arranged on the upper surface of the base 101 and arranged on the left and right, an upper cross frame 103 fixedly arranged on the top of the support column 102, and a lower cross frame 104 fixedly arranged in the middle of the support column 102. Among them, the cylinder body of the hydraulic cylinder 3 is fixedly arranged in the upper cross frame 103, and the test platform 2 is fixedly arranged on the upper surface of the lower cross frame 104. A protective cover 4 is placed on the upper surface of the test platform 2 and outside the metal material.

[0019] The upper surface of the protective cover 4 is provided with a through hole 401 adapted to the piston rod of the hydraulic cylinder 3. The through hole 401 allows the piston rod of the hydraulic cylinder 3 to extend into the protective cover 4 and squeeze the metal material downward. The upper surface of the test platform 2 is fixed with a support 5, on which a transparent explosion-proof glass 6 is fixed. The front side wall of the protective cover 4 is provided with an observation hole 402 adapted to the transparent explosion-proof glass 6. The support 5 vertically fixes the transparent explosion-proof glass 6 above the test platform 2 to provide visual protection for observing metal materials. The transparent explosion-proof glass 6 and the protective cover 4 form a rectangular structure cover body, which effectively prevents the metal to be tested from splashing around. The left and right side walls of the protective cover 4 are fixed with positioning pieces 403, and the upper surface of the test platform 2 is fixed with a positioning seat 7, which is connected to the positioning piece 403 through a butterfly bolt 8. The utility model can directly remove the protective cover 4 from the test platform 2 by removing the butterfly bolt 8, so the upper surface of the test platform 2 is completely exposed, which is convenient for placing the metal to be tested and cleaning metal debris. The protective cover 4 and the transparent explosion-proof glass 6 adopt a split design, which reduces the mass of the protective cover 4 and facilitates the transportation of the protective cover 4. The protective cover 4 is made of steel plate, and the unit price of the protective cover 4 is much lower than the unit price of the transparent explosion-proof glass 6. Compared with the cover body made of explosion-proof glass, the cover body composed of the protective cover 4 and the transparent explosion-proof glass 6 in the utility model is low in price.

[0020] On the basis of the above embodiments, on the upper surface of the protective cover 4 and on the left and right sides of the through hole 401, handles 404 are fixedly provided. The handles 404 provide a force application point for carrying the protective cover 4. Rubber buffer blocks 405 are fixedly provided on the inner wall of the protective cover 4. The rubber buffer blocks 405 reduce the damage to the inner wall of the protective cover 4 caused by metal splashing. An explosion-proof lamp cover 406 is fixedly provided on the inner wall of the protective cover 4. The explosion-proof lamp cover 406 penetrates through the rubber buffer block 405. On the inner wall of the protective cover 4 and inside the explosion-proof lamp cover 406, a lighting strip 407 is fixedly provided. The lighting strip 407 is an LED lighting strip and is located at the top of the protective cover 4. The lighting strip 407 provides illumination inside the protective cover 4, facilitating the real-time viewing of the test process, especially applicable to places with poor ambient light sources. A storage battery and a switch are fixedly provided on the outer wall of the protective cover 4. The storage battery, the switch, and the lighting strip 407 form a series circuit. Through the switch, the tester can turn on or off the lighting strip 407 outside the protective cover 4.

[0021] On the basis of the above embodiments, the transparent explosion-proof glass 6 has a rectangular structure. A transparent scratch-resistant protective film is adhered to the rear side wall of the transparent explosion-proof glass 6. The transparent scratch-resistant protective film is a PET scratch-resistant protective film, which can effectively prevent the transparent explosion-proof glass 6 from being scratched by metal debris splashing.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
