[0002] In the modern industrial field, cutting torches are widely used in the cutting operation of metal materials. The copper tube special for cutting torches, as one of the key components of the cutting torch, undertakes important tasks such as transporting fuel gas or combustion-supporting gas.

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0042] like Figures 1 to 4 As shown, the wear resistance testing device for copper tubes used in cutting torches according to this utility model includes:
[0043] Support plate 1 is set on the ground;
[0044] The wear resistance and pressure resistance testing mechanism 2 is set on the support plate 1 and is used to perform wear resistance and pressure resistance tests on the copper tube.
[0045] The pressure test tube fixing mechanism 3 is set on the support plate 1 and is used to fix the copper tube for pressure testing;
[0046] Drive component 4, mounted on support base plate 1, is used to drive wear resistance and compressive strength testing mechanism 2;
[0047] Four sets of clamping assemblies 5, two sets of clamping assemblies 5 are provided on the support base plate 1 for fixing the copper tube for wear resistance test, and two sets of clamping assemblies 5 are provided on the pressure resistance test tube fixing mechanism 3 for fixing the copper tube for pressure resistance test.
[0048] Among them, the wear resistance and compressive strength testing unit 2 includes:
[0049] Test support frame 21 is fixedly installed on support base plate 1;
[0050] The test slide 22 is horizontally slidably mounted on the test support frame 21;
[0051] The height adjustment screw 23 is vertically rotatable and mounted on the test slide plate 22;
[0052] The hoisting frame 24 is vertically slidably mounted on the test slide plate 22 and is threadedly engaged with the height adjustment screw 23, which drives it to slide up and down.
[0053] Friction block 25 is set at the bottom of the lifting frame 24 and is used to rub the surface of the copper tube for testing;
[0054] The pressure tube bracket 26 is fixedly installed on the test slide plate 22;
[0055] The pressure plate 27 is fixedly installed on the pressure tube bracket 26 and slides horizontally through the test slide plate 22.
[0056] The working process and principle of the device are as follows: The copper tube for the cutting torch to be tested is cut into two test sections, ensuring that the length and specifications of the test sections meet the testing requirements; the support plate 1 is fixed to the ground to ensure the stability of the device; the height adjustment screw 23 is adjusted so that the hoisting frame 24 and friction block 25 are at a suitable height for wear resistance testing; two sets of tube clamping assemblies 5 are used to fix one end of the test copper tube to the support plate 1, ensuring that the copper tube is stable and horizontal; the other end of the test copper tube is fixed to the pressure-resistant plate using two other sets of tube clamping assemblies 5. On the test tube fixing mechanism 3, the copper tube position is also ensured to be stable; the drive assembly 4 is activated, driving the test slide plate 22 to slide horizontally on the test support frame 21; the test slide plate 22 drives the hanging frame 24 and the friction block 25 to move together, so that the friction block 25 contacts the surface of the copper tube fixed on the support plate 1 and generates friction; by controlling the movement speed of the drive assembly 4 and the pressure of the friction block 25, the friction conditions of the copper tube in actual use are simulated to conduct the wear resistance test; while conducting the wear resistance test, the pressure plate 27 is fixed to the pressure test tube. The copper tube surface is in contact with the fixing mechanism 3; by applying vertical pressure, the pressure condition of the copper tube in actual use is simulated to conduct a pressure test; after the test, the wear and deformation of the copper tube surface are checked to evaluate its wear resistance and pressure resistance; based on the test results, the quality of the copper tube is judged, and improvement suggestions are provided for subsequent production and application; this device can simultaneously comprehensively evaluate the wear resistance and pressure resistance of the copper tube, improving testing efficiency and accuracy; by cutting two sections from the same copper tube for two tests, errors and deviations in the testing process are reduced, improving the reliability of the test results; by setting the wear resistance and pressure resistance testing mechanism in the same device, wear resistance and pressure resistance tests can be performed on the copper tube simultaneously, changing the previous situation where some devices could only perform a single test, improving testing efficiency and accuracy; four sets of tube clamping assemblies are respectively set on the support base plate and the pressure test tube fixing mechanism. The reasonable fixing method ensures the stability of the tested copper tube during the testing process, reduces the deviation of test results caused by unreasonable fixing, and improves the accuracy and reliability of the test results.
[0057] The pressure tube support 26 is equipped with reinforcing ribs; these ribs improve its pressure resistance; the reinforcing ribs and the pressure tube support body form a more robust overall structure, enhancing the pressure tube support's resistance to bending moment and shear; the addition of reinforcing ribs makes the pressure tube support 26 less prone to deformation under pressure, maintaining its original shape and size; it helps improve the accuracy of the test, as the deformation of the pressure tube support directly affects the pressure distribution and magnitude applied to the copper tube by the pressure plate; the reinforcing ribs can disperse the stress generated by the pressure tube support 26 under pressure, avoiding stress concentration that could lead to localized damage; it helps extend the service life of the pressure tube support, reducing the risk of cracks and fractures caused by stress concentration; the reinforcing ribs improve the overall stability of the pressure tube support 26, making it less prone to shaking or tilting during testing; it helps ensure the smooth progress of the test and improves the reliability and accuracy of the test results.
[0058] The friction block 25 is slidably inserted into the bottom of the lifting frame 24, with the insertion direction of the friction block 25 perpendicular to the test movement direction. The friction block 25 is installed at the bottom of the lifting frame 24 via this sliding insertion method, allowing for adjustments or replacements of the friction block 25 perpendicular to its test movement direction, thus improving the flexibility and maintainability of the device. The installation direction of the friction block 25 is perpendicular to its test movement direction, ensuring stable support and fixation at the bottom of the lifting frame 24. This ensures that the friction block 25 will not shift or fall off due to force during testing, improving the accuracy and reliability of the test. The sliding insertion design makes the friction block 25 easy to replace and adjust. When the friction block wears out or needs to be replaced with a friction block of a different material, it can be easily replaced via the sliding insertion method. This improves the flexibility and maintainability of the device, reducing testing costs and maintenance difficulty.
[0059] The pressure test tube fixing mechanism 3 includes:
[0060] Two adjusting slides 31 are symmetrically and fixedly installed on the support plate 1;
[0061] Adjusting the fixing bracket 32, which is horizontally slidably mounted between two adjusting slide blocks 31, wherein two sets of clamping tube assemblies 5 are arranged vertically opposite each other on the left end face of the adjusting fixing bracket 32;
[0062] The horizontal adjusting screw 33 is rotatably mounted on the support base plate 1 and threadedly engaged with the adjusting fixing frame 32 to drive the adjusting fixing frame 32 to slide horizontally.
[0063] The working process and principle of the pressure resistance test tube fixing mechanism 3 are as follows: Before the pressure resistance test, the copper tube is placed between the two sets of clamping components 5 on the left end face of the adjusting fixing frame 32, and the copper tube is firmly fixed by the clamping components 5; according to the test requirements, the horizontal adjusting screw 33 is rotated to drive the adjusting fixing frame 32 to slide horizontally in the adjusting slide block 31, thereby adjusting the position of the copper tube to ensure that it is aligned with the pressure plate 27 in the wear-resistant and pressure-resistant test mechanism 2; after the position of the copper tube is adjusted, the driving component 4 is activated to drive the test slide plate 22 in the wear-resistant and pressure-resistant test mechanism 2 to slide horizontally, thereby driving the pressure plate 27 to apply pressure to the copper tube for the pressure resistance test; during the test, the pressure resistance test tube fixing mechanism 3 ensures that the position of the copper tube is stable and not affected by external forces, thereby ensuring the accuracy of the test results; the pressure resistance test tube fixing mechanism 3 and the wear-resistant and pressure-resistant test mechanism 2 work together to realize the comprehensive test of the wear resistance and pressure resistance of the copper tube; by adjusting the position of the copper tube and the applied pressure, the complex working conditions of the copper tube in actual use can be simulated to evaluate its comprehensive performance, thereby improving the accuracy and reliability of the test.
[0064] Both the horizontal adjusting screw 33 and the height adjusting screw 23 have handwheels at their input ends. When horizontal adjustment is needed, the operator holds the handwheel on the horizontal adjusting screw 33 and rotates it clockwise or counterclockwise to drive the horizontal adjusting screw 33 to rotate. Similarly, when the height of the lifting frame 24 needs to be adjusted, the operator holds the handwheel on the height adjusting screw 23 and rotates it. When the horizontal adjusting screw 33 rotates, the adjusting fixing bracket 32, which is threaded with it, slides horizontally within the adjusting slide block 31, thereby adjusting the horizontal position of the pressure test tube fixing mechanism 3. When the height adjusting screw 23 rotates, the lifting frame 24, which is threaded with it, slides vertically on the test slide plate 22, thereby adjusting the height of the friction block 25 for friction testing of the copper tube surface. The handwheel serves as the operating interface, providing a convenient manual adjustment method. By rotating the handwheel, the operator can easily control the rotation of the screw, thereby achieving precise adjustment and improving the operator's comfort and work efficiency.
[0065] The support plate 1 has four rubber feet 11 arranged at the bottom corners. During operation, these feet act as support points, bearing the weight of the entire device and its components. They evenly distribute the pressure on the support plate, preventing deformation or damage due to excessive local stress. The rubber feet 11 also absorb and dampen vibrations during testing, preventing them from being transmitted to the ground or other equipment. This helps maintain the accuracy and reliability of the test while reducing noise pollution. The four rubber feet 11 at the bottom corners of the support plate 1 in the copper tube abrasion resistance testing device for cutting torches, through elastic support, vibration damping, and anti-slip properties, ensure the stability and accuracy of the device during testing. This not only improves the reliability and durability of the device but also reduces noise pollution and safety hazards.
[0066] The clamp assembly 5 includes:
[0067] The cylinder support 51 is fixedly connected to the corresponding support plate 1 and the adjusting and fixing bracket 32;
[0068] Two clamping cylinders 52 are symmetrically fixedly mounted on cylinder supports 51;
[0069] Two pipe clamping blocks 53 are fixedly connected to the output ends of two pipe clamping cylinders 52, respectively;
[0070] The working process and principle of the pipe clamping assembly 5 are as follows: When it is necessary to clamp the copper pipe, the pneumatic system provides compressed air to the pipe clamping cylinder 52, driving the cylinder piston to move forward; the movement of the cylinder piston drives the pipe clamping block 53 to approach the copper pipe until the clamping block is in close contact with the surface of the copper pipe, generating sufficient clamping force to fix the copper pipe; during the test, the pipe clamping assembly 5 keeps the copper pipe stable and fixed, ensuring that the copper pipe will not move or fall off during the wear resistance test and pressure test; the magnitude of the clamping force can be controlled by adjusting the pressure of the pneumatic system to adapt to copper pipes of different specifications and materials; the pipe clamping cylinder 52 uses compressed air as a power source, converting pneumatic energy into mechanical energy through the piston and rod in the cylinder, driving the pipe clamping block 53 to move; the pressure and flow of the pneumatic system can be controlled by valves and regulators to achieve precise clamping force adjustment; this not only improves the accuracy and reliability of the test, but also enhances the applicability and flexibility of the device.
[0071] Each pipe clamp 53 is equipped with a clamping rubber pad 54. During the test, the clamping rubber pad 54 maintains close contact with the copper pipe, ensuring that the copper pipe will not move or fall off during the wear resistance and pressure resistance tests. The elasticity of the rubber pad can also absorb the vibration and impact generated during the test, protecting the copper pipe from damage. The elasticity of the clamping rubber pad 54 allows it to adapt to the slight deformation of the copper pipe during clamping, preventing the copper pipe from being deformed or damaged by excessive local pressure. The buffering effect of the rubber pad can also reduce the vibration and impact generated during the test, improving the accuracy and reliability of the test. The wear resistance of the rubber pad also allows it to maintain a good clamping effect during long-term use, extending the service life of the testing device.
[0072] The wear resistance testing device for copper tubes for cutting torches of this utility model can be installed, connected, or set up using common mechanical methods. Any method that can achieve its beneficial effect can be implemented.
[0073] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
