Description

Technical Field

[0001] This invention relates to the field of hose testing technology, and in particular to a batch testing device for the tensile strength of finished hose winding products. Background Technology

[0002] Spiralized hose refers to a finished hose product made by spirally winding high-strength steel wire or fiber at a specific angle onto the inner layer of the hose as a skeleton layer, then covering it with outer rubber and vulcanizing it. This structure gives it excellent resistance to pulse fatigue, making it particularly suitable for applications with frequent fluctuations in working pressure (such as hydraulic systems of engineering machinery). Its finished product status means that it has passed all quality inspections and possesses all the performance requirements for leaving the factory and for use.

[0003] Before leaving the factory, finished rubber hoses need to undergo tensile testing to verify their actual strength. In actual production lines, tensile testing machines are typically used to clamp the finished hoses and then measure their strength. However, existing tensile testing machines usually use external clamps to hold the hose openings. To overcome the enormous tensile force, the clamps need to "bite" the hose from the outside with tremendous force. This force is concentrated on a very small area on the outer wall of the hose, generating enormous pressure that can easily crush or cut the outer steel wire or rubber, leading to damage to the hose openings. For example, a hose tensile strength testing device disclosed in patent application CN201921256456.9 also confirms this problem. Even using pressure blocks and vertical grooves to clamp the hose openings cannot effectively prevent damage to the hoses during clamping.

[0004] Therefore, how to provide a batch testing device for the tensile strength of finished hose winding products is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a batch testing device for the tensile strength of finished hose winding products, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a batch testing device for the tensile strength of finished hose winding products, including a stretching machine body and a loading and unloading assembly. A worktable is fixedly connected to the top of the stretching machine body, and a storage box is fixedly connected to the rear side of the top of the worktable. A tensile testing drive mechanism is provided on the right side of the top of the worktable. A fixed clamp is provided in the middle of the left side of the worktable. A movable plate is provided on the left side of the tensile testing drive mechanism. When the tensile testing drive mechanism is working, it can drive the movable plate to move left and right inside the worktable.

[0007] The loading and unloading assembly includes:

[0008] A feeding sloping plate is fixedly connected to the front side of the bottom of the storage box. A drive motor is fixedly connected to the bottom of the storage box on the left side of the feeding sloping plate. The drive motor has an output shaft, and a feeding lever is fixedly connected to the output shaft of the drive motor. A waste discharge sloping plate is fixedly connected to the rear side of the bottom of the worktable. A waste trough with the top and bottom penetrating each other is opened on the rear side of the worktable near the middle. A receiving sloping plate is fixedly connected to the top of the worktable in front of the waste trough. A positioning horizontal plate is fixedly connected to the top of the front of the receiving sloping plate. A discharge sloping plate is fixedly connected to the top of the back of the fixed discharge rack.

[0009] Furthermore, it also includes a lifting assembly, which consists of a protective shell, an electric lifting rod, a lifting plate, a lifting base, a spring, a deformation plate, a hose support frame, and a protective plate.

[0010] The workbench has a lifting groove that runs through the top and bottom. The protective shell is fixedly connected to the bottom of the workbench and located on the left side of the lifting groove. The electric lifting rod is fixedly connected to the bottom of the protective shell. The electric lifting rod has a telescopic end. The lifting plate is fixedly connected to the telescopic end of the electric lifting rod. The lifting base is fixedly connected to the side of the lifting plate away from the protective shell. A spring is fixedly connected to the top of the lifting base. The deformation plate is fixedly connected to the top of the spring. The hose receiving frame is fixedly connected to the top of the deformation plate. The protective plate is fixedly connected to the front side of the top of the hose receiving frame.

[0011] Furthermore, it also includes a movable clamp, which consists of a movable seat, a fixed shell, an outer clamping ring seat, an electric telescopic rod, a fixed block, a connecting rod, a conical extrusion block, a guide groove, a sliding block, a moving frame, an arc-shaped extrusion plate, a spring, and an arc-shaped bidirectional telescopic rod.

[0012] The movable seat is fixedly connected to the middle left side of the movable plate. The fixed shell is fixedly connected to the left side of the movable seat. The outer clamping annular seat is fixedly connected to the side of the fixed shell away from the movable seat. The electric telescopic rod is fixedly connected inside the fixed shell. The fixed block is fixedly connected to the middle part of the outer clamping annular seat near the fixed shell. The electric telescopic rod has a telescopic end. The connecting rod is fixedly connected to the telescopic end of the electric telescopic rod. The conical extrusion block is fixedly connected to the end of the connecting rod away from the electric telescopic rod. The guide groove is fixedly connected inside the outer clamping annular seat and located outside the fixed block. The sliding block is slidably connected inside the guide groove. The moving frame is fixedly connected to the side of the sliding block away from the fixed shell. The arc-shaped extrusion plate is fixedly connected to the side of the moving frame away from the fixed block. The second spring is fixedly connected to the side of the moving frame near the fixed block. The arc-shaped bidirectional telescopic rod is fixedly connected to the outside of the moving frame.

[0013] Furthermore, the storage box contains finished rubber tubes, and the feeding lever is located at the bottom of the feeding ramp. When the drive motor is working, it can drive the feeding lever to rotate. When the feeding lever rotates, it can rotate inside the feeding ramp. When the rubber tube is at the top of the feeding ramp, the rotation of the feeding lever can flip the steel tubes one by one from the top of the feeding ramp. The waste discharge ramp is located at the bottom of the waste trough.

[0014] Furthermore, the lifting base, spring one, deformation plate, hose receiving frame, and protective plate are all set in the lifting groove. The lifting plate is set inside the protective shell. The lifting end of the electric lifting rod passes through the bottom of the protective shell and extends into the protective shell to be fixedly connected to the bottom of the lifting plate. When the electric lifting rod is working, it can drive the lifting plate to rise and fall inside the protective shell.

[0015] Furthermore, the lifting base and the deformation plate are provided with receiving grooves on their front sides, which allow the discharge inclined plate to be inserted into the receiving grooves when the lifting base and the deformation plate are lowered.

[0016] Furthermore, a sliding groove is provided in the middle of the fixed block, and the telescopic end of the electric telescopic rod passes through the fixed shell, the outer clamping ring seat and the sliding groove and extends to the other side of the fixed block to be fixedly connected to the connecting rod. When working, the electric telescopic rod can drive the connecting rod and the conical extrusion block to move up and down in the outer clamping ring seat.

[0017] Furthermore, the inner wall of the outer clamping annular seat is provided with a friction pad ring, the side of the arc-shaped extrusion plate away from the fixed block is provided with a friction plate, and the side of the spring away from the moving frame is fixedly connected to the outside of the fixed block.

[0018] Furthermore, the number of the guide groove, sliding block, moving frame, arc-shaped extrusion plate, spring II, and arc-shaped bidirectional telescopic rod are all four. The four guide grooves, sliding blocks, moving frames, arc-shaped extrusion plates, spring II, and arc-shaped bidirectional telescopic rods are arranged in a ring around the outside of the fixed block, and two adjacent moving frames are connected by arc-shaped bidirectional telescopic rods.

[0019] Furthermore, the side of the movable frame closest to the conical extrusion block is set as an arc surface, which can extrude the movable frame when the conical extrusion block rises and falls, and can synchronously drive the movable frame and the arc extrusion plate to move when the sliding block slides in the guide groove.

[0020] Furthermore, the fixed clamp and the moving clamp have the same internal structure. The arc-shaped bidirectional telescopic rod can connect the four arc-shaped extrusion plates and form a ring, which can make the four arc-shaped extrusion plates move synchronously, so that the inner side of the hose head is evenly stressed and point clamping is avoided. A non-contact extensometer is provided on the front of the workbench.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention adopts an annular surface contact clamping with "inner support and outer hoop", which completely replaces the traditional point contact clamping method. This avoids initial damage such as crushing and cutting to the hose head during the clamping stage, and ensures that the test results truly reflect the strength of the hose body, rather than the strength of the weak points of clamping.

[0023] 2. In this invention, the cone-shaped extrusion block drives the linkage mechanism to ensure that the four arc-shaped extrusion plates move radially synchronously, so that the inner circumference of the hose head is subjected to uniform force, thus avoiding test data deviation or premature breakage caused by eccentric force.

[0024] 3. In this invention, the fixed clamp and the moving clamp have the same structure, which not only simplifies manufacturing and maintenance, but also ensures that the clamping effect on both ends of the hose is completely consistent, thereby improving the repeatability and accuracy of the test.

[0025] 4. This invention, through the coordinated operation of the storage bin, the feeding lever, and the lifting mechanism, achieves automatic, single-piece, and orderly feeding of hoses without manual intervention, laying the foundation for continuous batch testing;

[0026] 5. According to the present invention, the device can automatically execute different feeding paths based on the detection results. When the product is detected as qualified, it is smoothly fed out through the discharge inclined plate. When the unqualified product is detected, the hose receiving frame can tilt and automatically guide it into the waste trough, realizing automatic separation and classification, avoiding errors and inefficiency of manual sorting.

[0047] The workbench 2 has a lifting groove that runs through the top and bottom. The protective shell 501 is fixedly connected to the bottom of the workbench 2 and is located on the left side of the lifting groove. The electric lifting rod 502 is fixedly connected to the bottom of the protective shell 501. The electric lifting rod 502 has a telescopic end.

[0048] The storage bin 3 contains finished rubber hoses. The feeding lever 402 is located at the bottom of the feeding ramp 403. When the drive motor 401 is working, it can drive the feeding lever 402 to rotate. When the feeding lever 402 rotates, it can rotate inside the feeding ramp 403. When the rubber hose is at the top of the feeding ramp 403, the rotation of the feeding lever 402 can flip the steel pipes one by one from the top of the feeding ramp 403. The waste discharge ramp 404 is located at the bottom of the waste trough.

When the electric lifting rod 502 is working, it can drive the lifting plate 503 to rise and fall inside the protective shell 501.

[0050] The lifting base 504 and the deformation plate 506 have a receiving groove 409 on their front sides. When the lifting base 504 and the deformation plate 506 descend, the discharge inclined plate 408 can be inserted into the receiving groove 409.

[0051] Example 2

[0052] refer to Figure 9-12 Based on Embodiment 1, the present invention provides a technical solution that further includes a movable clamp 9, which is composed of a movable seat 901, a fixed shell 902, an outer clamping ring seat 903, an electric telescopic rod 904, a fixed block 905, a connecting rod 906, a conical extrusion block 907, a guide groove 908, a sliding block 909, a moving frame 910, an arc-shaped extrusion plate 911, a second spring 912, and an arc-shaped bidirectional telescopic rod 913.

[0053] Movable seat 901 is fixedly connected to the middle left side of movable plate 8. Fixed shell 902 is fixedly connected to the left side of movable seat 901. External clamping ring seat 903 is fixedly connected to the side of fixed shell 902 away from movable seat 901. Electric telescopic rod 904 is fixedly connected inside fixed shell 902. Fixed block 905 is fixedly connected to the middle part of the side of external clamping ring seat 903 near fixed shell 902. Electric telescopic rod 904 has a telescopic end. Connecting rod 906 is fixedly connected to the telescopic end of electric telescopic rod 904. Conical extrusion block 907 is fixedly connected to connecting rod 904. 06. At the end away from the electric telescopic rod 904, the guide groove 908 is fixedly connected to the outer clamping ring seat 903 and located outside the fixed block 905. The sliding block 909 is slidably connected to the inside of the guide groove 908. The moving frame 910 is fixedly connected to the side of the sliding block 909 away from the fixed shell 902. The arc-shaped extrusion plate 911 is fixedly connected to the side of the moving frame 910 away from the fixed block 905. The second spring 912 is fixedly connected to the side of the moving frame 910 close to the fixed block 905. The arc-shaped bidirectional telescopic rod 913 is fixedly connected to the outside of the moving frame 910.

[0054] A sliding groove is provided in the middle of the fixed block 905. The telescopic end of the electric telescopic rod 904 passes through the fixed shell 902, the outer clamping ring seat 903 and the sliding groove and extends to the other side of the fixed block 905 and is fixedly connected to the connecting rod 906. When working, the electric telescopic rod 904 can drive the connecting rod 906 and the conical extrusion block 907 to rise and fall within the outer clamping ring seat 903.

[0055] The inner wall of the outer clamping ring seat 903 is provided with a friction pad ring, the arc-shaped extrusion plate 911 is provided with a friction plate on the side away from the fixed block 905, and the spring 912 is fixedly connected to the outer side of the fixed block 905 on the side away from the moving frame 910.

[0056] The guide groove 908, sliding block 909, moving frame 910, arc-shaped extrusion plate 911, spring 912 and arc-shaped bidirectional telescopic rod 913 are all in four quantities. The four guide grooves 908, sliding blocks 909, moving frames 910, arc-shaped extrusion plates 911, spring 912 and arc-shaped bidirectional telescopic rod 913 are arranged in a ring on the outside of the fixed block 905. The two adjacent moving frames 910 are connected by the arc-shaped bidirectional telescopic rod 913.

[0057] The movable frame 910 is set with an arc surface on the side near the conical extrusion block 907. When the conical extrusion block 907 rises and falls, it can extrude the movable frame 910. When the sliding block 909 slides in the guide groove 908, it can simultaneously drive the movable frame 910 and the arc extrusion plate 911 to move.

[0058] The fixed clamp 7 and the movable clamp 9 have the same internal structure. The arc-shaped bidirectional telescopic rod 913 can connect the four arc-shaped extrusion plates 911 and form a ring. It can make the four arc-shaped extrusion plates 911 move synchronously, so that the inner side of the hose head is evenly stressed and point clamping is avoided. A non-contact extensometer is provided on the front of the inner side of the workbench 2.

[0059] When loading and unloading finished hoses, the finished hoses are placed inside the storage bin 3. The finished hoses accumulate inside the storage bin 3. The electric lifting rod 502 is then activated, causing the lifting plate 503 to rise within the protective shell 501. As the lifting plate 503 rises, it causes the lifting base 504, spring 505, deformation plate 506, hose receiving frame 507, and protective plate 508 to rise from the lifting slot on the workbench 2. The hose receiving frame 507 and the protective plate 508 are moved to the upper side of the worktable 2. Then, the drive motor 401 is controlled to work, causing the drive motor 401 to drive the feeding lever 402 to rotate. When the feeding lever 402 rotates, it can flip the hoses one by one, allowing the hoses to roll down through the feeding ramp 403 to the top of the hose receiving frame 507. By setting the protective plate 508, the hoses can be prevented from rolling down from the top of the hose receiving frame 507, thus completing the rapid feeding of hoses. After the tensile strength test is completed, the electric lifting rod 502 is activated. When the electric lifting rod 502 is activated, the lifting plate 503 rises within the protective housing 501, allowing the hose receiving frame 507 to re-contact and support the bottom of the hose. Then, the moving clamp 9 and the fixed clamp 7 are controlled to separate the hose from the receiving frame, causing the hose to fall back above the hose receiving frame 507. Finally, the electric lifting rod 502 is controlled to lower the lifting plate 503 within the protective housing 501, allowing the lifting base to... During the descent of 504 and deformation plate 506, the discharge ramp 408 can contact and support the hose. As the lifting base 504 and deformation plate 506 continue to descend, the hose receiving frame 507 can move to the underside of the discharge ramp 408, separating the hose from the hose receiving frame 507. Subsequently, the hose moves onto the discharge ramp 408 and, under the action of gravity, automatically slides down the ramp on the discharge ramp 408 and is delivered, enabling the device to quickly load and unload materials during use.

[0060] When a rapid tensile strength test is required on the hose, the hose is placed above the hose receiving frame 507. The tensile testing drive mechanism 6 operates, causing the movable plate 8 to drive the movable clamp 9 to move to the left within the worktable 2. This causes the movable clamp 9 to contact the hose and push it towards the fixed clamp 7 until one end of the hose is inserted into the fixed clamp 7 and the other end is inserted into the outer clamping ring seat 903. At this point, the conical extrusion block 907 is inserted into the hose opening, controlling the electric telescopic movement. When rod 904 operates, it drives the conical extrusion block 907 to move towards one side of the electric telescopic rod 904 via connecting rod 906. As the conical extrusion block 907 moves, it contacts the moving frame 910 and compresses it, stretching the spring 912 on the moving frame 910. Simultaneously, the sliding block 909 at the bottom of the moving frame 910 slides within the guide groove 908, causing the arc-shaped extrusion plate 911 to move away from the fixed block 905 as the moving frame 910 moves. The tubing head is moved to one side, causing the arc-shaped extrusion plate 911 to contact the inner wall of the tubing head, while the outer wall of the tubing head contacts the inner wall of the outer clamping ring seat 903. This allows the tubing head to be clamped by both the arc-shaped extrusion plate 911 and the outer clamping ring seat 903. The friction pads on the arc-shaped extrusion plate 911 and the friction pad ring inside the outer clamping ring seat 903 effectively clamp the tubing head. Compared to the point clamping used in existing technologies, this method, through the cooperation of the arc-shaped extrusion plate 911 and the inner wall of the outer clamping ring seat 903, effectively clamps the tubing head. The surface clamping effectively avoids damage at the clamping point. Since the fixed clamp 7 and the movable clamp 9 have the same internal structure, both can clamp the hose head with the same structure and have the same effect. After clamping the hose, the tensile testing drive mechanism 6 can control the movable plate 8 and the movable seat 901 to move away from the fixed clamp 7. When the movable seat 901 moves, the hose can be stretched, allowing the device to test the tensile strength of the hose.

[0061] When testing the tensile strength of the hose, if the hose is of qualified quality and has no obvious cracks or breaks, the tensile testing drive mechanism 6 is activated. This mechanism pushes the movable plate 8 and movable seat 901 towards the fixed clamp 7, causing the hose to automatically spring back. After the hose returns to its original state, the electric lifting rod 502 is activated, moving the hose receiving frame 507 to the underside of the hose and lifting it. Then, the electric telescopic rod 904 is activated, pushing the connecting rod 906 and the conical extrusion block 907 to separate the conical extrusion block 907 from the moving frame 910. At this time, the spring 912 recovers its elasticity, allowing the moving frame 910 to move towards the fixed block 905, separating the arc-shaped extrusion plate 911 from the inner wall of the hose head, allowing the hose to fall to the top of the hose receiving frame 507. When the hose meets the requirements, the electric lifting rod 502 controls the hose receiving frame 507 to descend. The system allows the hose to slide out through the discharge ramp 408. When the hose does not meet the requirements, the electric lifting rod 502 controls the hose receiving frame 507 to rise, allowing the hose receiving frame 507 to contact the positioning cross plate 406 on the receiving ramp 405. Then, the electric lifting rod 502 continues to operate, allowing the hose receiving frame 507 to continue rising. Because the positioning cross plate 406 limits the rear top of the hose receiving frame 507, it can... The hose receiving frame 507 is squeezed, and the spring 505 is compressed, causing the rear side of the hose receiving frame 507 to press down while the front side of the hose receiving frame 507 rises. This allows the hose on the hose receiving frame 507 to tilt and fall onto the receiving inclined plate 405, and then slide down through the receiving inclined plate 405 to fall through the waste trough onto the waste discharge inclined plate 404. The hose is then sent out through the inclined surface on the waste discharge inclined plate 404, giving the device the functions of automatic material discharge and automatic waste discharge.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
