Technical Field
[0001] The utility model relates to the technical field of pressure testing machines, in particular to a pressure testing machine for high-pressure pipe fitting forming production. Background Art
[0002] The pressure testing machine for high-pressure pipe fittings forming production is a device designed specifically for pressure testing of high-pressure pipe fittings during the forming production process. This testing machine plays a vital role in the production line of high-pressure pipe fittings, and can ensure that the pressure resistance and sealing performance of the pipe fittings meet the predetermined standards. The core component of the pressure testing machine is the sensor, which is responsible for converting physical quantities (i.e. pressure) into electrical signals. When the high-pressure pipe fittings being tested are subjected to pressure, the sensor can sense the changes in pressure and generate corresponding electrical signals, thereby testing the pressure resistance of the high-pressure pipe fittings.
[0003] The pressure testing machine can test the compressive performance of high-pressure pipe fittings to ensure that the pressure resistance of the pipe fittings reaches the predetermined standard. The table top of the pressure testing machine is mostly open, and high-pressure pipe fittings can only be placed on its surface. The pressure plate is used to apply pressure to the top of the high-pressure pipe fitting. When the pressure plate contacts the top of the high-pressure pipe fitting, the high-pressure pipe fitting may not be in a vertical horizontal line with the pressure plate. After being squeezed, it may shift in position and move left and right, which will affect the results of the pressure test. Therefore, it is particularly important to design a pressure testing machine for high-pressure pipe fitting forming production. Utility Model Content

[0026] Working principle: The pressure testing machine for high-pressure pipe fittings forming production is a device designed for pressure testing of high-pressure pipe fittings during the forming production process. This testing machine plays a vital role in the production line of high-pressure pipe fittings and can ensure that the pressure resistance and sealing performance of the pipe fittings meet the predetermined standards. The core component of the pressure testing machine is the sensor, which is responsible for converting the physical quantity, namely pressure, into an electrical signal. When the high-pressure pipe fitting being tested is subjected to pressure, the sensor can sense the change in pressure and generate a corresponding electrical signal, thereby testing the pressure resistance of the high-pressure pipe fitting. The staff can manually place the high-pressure pipe fitting on the surface of the test bench 3 and between the two clamping rings 13. At this time, after the staff rotates the two torsion rods 7 clockwise in turn, the outer surface of the push frame 9 is always in contact with the inner surface of the support frame 6.

After one end of the first rotating column 15 is embedded in the interior of the support block 14 and the first concave hole 16, the three are threadedly connected, and then the pushing frame 9 and the auxiliary block 11 can be limited and fixed to ensure the stability of the clamping ring 13. The clamping ring 13 and the auxiliary block 11 are connected by two positioning bars 12. Through the movement of the auxiliary block 11, under the action of the positioning bar 12, the clamping ring 13 will be driven to move. The moving plate 5 and one end of the horizontal rod 4 are movably sleeved, and the area where the two clamping rings 13 move on the surface of the test bench 3 can be further adjusted. After one end of the second rotating column 17 is connected to the internal thread of the moving plate 5 and the second concave hole 18, the moving plate 5 can be limited at the top of the test bench 3. At this time, the support frame 6 remains stable.
