Description
Technical Field
[0001] This utility model relates to the field of cable testing technology, specifically to a punching machine for cable testing. Background Technology
[0002] In cable production, quality inspection, and related scientific research, accurate testing of cable material properties is crucial. Cable testing punching machines, as key equipment for obtaining standard test samples, play an indispensable role in the entire testing process.
[0003] In practical cable testing, when it is necessary to test the performance of materials such as the cable's insulation and sheath, it is usually necessary to first cut the cable open and then obtain a flat material sample for punching. However, the existing operating method has many problems.
[0004] Currently, after cutting the cable, it is mainly handled manually, laid flat and pressed onto the worktable of the lamination machine for lamination. This manual operation method has significant drawbacks. Firstly, manual pressing makes it difficult to ensure the cable remains flat throughout the lamination process. During lamination, the cable may shift, wrinkle, or warp due to uneven external force or operator fatigue, resulting in inaccurate dimensions and irregular shapes of the cut samples, severely affecting the accuracy and reliability of test results. For example, during tensile strength testing, uneven samples may experience uneven stress during the test, leading to biased test data that fails to accurately reflect the actual performance of the cable material.
[0005] On the other hand, manual pressing is inefficient. Operators need to spend a lot of time and energy to ensure the cables are flat and secure, especially for cables being tested in batches. This method greatly prolongs the testing cycle and reduces work efficiency. In addition, prolonged manual operation can easily cause operator fatigue, further affecting work quality and efficiency.
[0006] Furthermore, manual operation lacks consistency and stability. Different operators may vary in the pressure, method, and duration of pressing, which can lead to fluctuations in the quality and performance of different batches of samples, making it difficult to conduct a uniform and accurate assessment of cable quality.
[0007] In summary, the existing manual method of laying and pressing cables during cable testing can no longer meet the requirements of modern cable testing for efficiency, accuracy, and stability. Therefore, there is an urgent need for a device that can automatically, efficiently, and stably lay and fix cut cables to improve the efficiency and accuracy of cable testing results. This invention aims to solve this problem. Utility Model Content
[0008] To address the aforementioned problems, this invention presents a punching machine for cable testing.
[0009] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0010] A punching machine for cable testing includes a cylinder with multiple grooves on its inner wall. A motor is mounted on the bottom inner wall of the cylinder, and a lead screw is locked to the output end of the motor via a coupling. A connecting block is threaded onto the outer wall of the lead screw. Multiple sliders are mounted on the outer wall of the connecting block and are slidably connected within the grooves. A support column is mounted on the top wall of the connecting block, and the top of the support column extends out of the cylinder and is provided with a top plate. A connecting rod is mounted on the right side of the bottom wall of the top plate, and a fixing mechanism is provided on the bottom wall of the connecting rod.
[0011] Furthermore, the fixing mechanism includes a pressure plate, and baffles are provided on both the front and rear sides of the top wall of the pressure plate. A cylinder is provided on the outer wall of the baffle, and a connecting seat is provided on the right end wall of the cylinder. A round rod is rotatably connected to the inner side wall between the connecting seats through a bearing, and a roller is interference-fitted to the outer wall of the round rod.
[0012] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the connecting seat through the bearing housing, and the inner ring of the bearing is interference-fitted with the outer wall of the round rod.
[0013] Furthermore, the pressure plate and the bottom of the outer wall of the roller are located on the same plane.
[0014] Furthermore, the support column has a hollow structure, and the outer wall of the lead screw is placed inside the support column.
[0015] The beneficial effects of this utility model are:
[0016] This device, through the synergistic action of the pressure plate and rollers, can effectively lay and fix the cut cable flat. Compared with manual pressing, this device can avoid problems such as cable movement, wrinkling or warping caused by uneven external force or operator fatigue, ensuring that the cable remains flat during the punching process. This results in precise dimensions and regular shapes of the punched samples, greatly improving the accuracy and reliability of the test results.
[0017] The device uses a motor to drive a lead screw to rotate, which in turn drives a series of structures to lay and fix the cable. The whole process is highly automated. Compared with manual operation, it greatly saves the time and effort that operators spend on ensuring the cable is flat and fixed. Especially for cables being tested in batches, it can significantly shorten the testing cycle and improve work efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] See Figure 1-3As shown, a punching machine for cable testing includes a cylinder 1. Multiple grooves are formed on the inner wall of the cylinder 1. A motor 2 is provided on the inner bottom wall of the cylinder 1. A lead screw 3 is locked to the output end of the motor 2 through a coupling. A connecting block 4 is threadedly connected to the outer wall of the lead screw 3. Multiple sliders 5 are provided on the outer wall of the connecting block 4, and the sliders 5 are slidably connected in the grooves. A support column 6 is provided on the top wall of the connecting block 4. The top of the support column 6 extends out of the cylinder 1 and is provided with a top plate 7. A connecting rod 8 is provided on the right side of the bottom wall of the top plate 7. A fixing mechanism is provided on the bottom wall of the connecting rod 8.
[0026] Furthermore, the fixing mechanism includes a pressure plate 9, with baffles 10 on both the front and rear sides of the top wall of the pressure plate 9. A cylinder 11 is provided on the outer wall of the baffle 10, and a connecting seat 12 is provided on the right end wall of the cylinder 11. A round rod 14 is rotatably connected to the inner wall between the connecting seats 12 through a bearing 13. A roller 15 is interference-fitted to the outer wall of the round rod 14. The pressure plate 9 and the roller 15 move downward to press on the outer wall of the cable, and the left end of the cable is fixed by the pressure plate 9. After the cylinder 11 is started, it pushes the connecting seat 12, the bearing 13, the round rod 14 and the roller 15 to move to the right. The roller 15 lays the cable flat and stretches it to the right. The roller 15 is moved to the right end of the cable and the right end of the cable is fixed.
[0027] Furthermore, the outer ring of the bearing 13 is fixedly connected to the inner wall of the connecting seat 12 through the bearing housing, and the inner ring of the bearing 13 is interference-fitted with the outer wall of the round rod 14. The bearing 13 fixes the round rod 14, making it easier for the round rod 14 to rotate through the bearing 13.
[0028] Furthermore, the pressure plate 9 and the bottom of the outer wall of the roller 15 are on the same plane. The pressure plate 9 and the roller 15 move downward to press on the outer wall of the cable. The pressure plate 9 fixes the left end of the cable. After the cylinder 11 is started, it pushes the connecting seat 12, bearing 13, round rod 14 and roller 15 to move to the right. The roller 15 presses on the cable and moves to the right. The roller 15 lays the cable flat and stretches it to the right, fixing the right end of the cable.
[0029] Furthermore, the support column 6 has a hollow structure, and the outer wall of the lead screw 3 is placed inside the support column 6. The motor 2 causes the lead screw 3 to rotate, and the lead screw 3 causes the connecting block 4 to move the support column 6, top plate 7, connecting rod 8, pressure plate 9, cylinder 11, connecting seat 12 and roller 15 downward or upward, so that the outer wall of the lead screw 3 can be housed inside the inner support column 6, which can reduce the height of the main body of the device.
[0030] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.
[0031] One specific application of this embodiment is:
[0032] When using this device, the first step is installation. We use welding to firmly install this cable laying and fixing device on the processing table of the punching machine. Welding ensures a stable and tight connection between the device and the punching machine processing table. In subsequent operations, it will not loosen or shift due to vibration or other external forces, providing a solid foundation for the entire cable laying and fixing and punching work.
[0033] After the device installation is completed, the cable processing stage begins. The cable that needs to be punched is cut according to the testing requirements. Then, the left end of the cable is unfolded and placed under the pressure plate 9 and roller 15. This placement position is carefully designed to ensure that subsequent operations can be carried out accurately and effectively.
[0034] Next, start motor 2. As one of the power sources of the entire device, motor 2 will cause lead screw 3 to rotate after it starts running. The rotation of lead screw 3 is the key link for the entire device to achieve precise action. As lead screw 3 rotates, the connecting block 4 connected to it will be displaced under the drive of lead screw 3. Since the connecting block 4 is closely connected to the support column 6, top plate 7, connecting rod 8, pressure plate 9, cylinder 11, connecting seat 12 and roller 15 through a specific mechanical connection method, the movement of connecting block 4 will drive these structures to move downward as a whole.
[0035] As these structures move downward, the pressure plate 9 and roller 15 gradually approach and eventually press against the outer wall of the cable. At this time, the pressure plate 9 plays an important role in fixing the cable, firmly fixing the left end of the cable to prevent the left end of the cable from moving or shaking during subsequent operations, and providing a stable starting point for subsequent laying and fixing work.
[0036] After the left end of the cable is successfully fixed, the cylinder 11 is activated to push the connecting seat 12 and the connected bearing 13, round rod 14 and roller 15 to move to the right. During the movement, the roller 15 always keeps in contact with the cable, and with the cooperation of the round rod 14 and the bearing 13, the roller 15 can rotate while pressing on the cable. This rotation design is of great significance. It can greatly reduce the friction between the roller 15 and the cable during the movement, making the movement of the roller 15 smoother and avoiding damage to the cable due to excessive friction. It also ensures that the cable can be spread out evenly and flat.
[0037] As the roller 15 continues to move to the right, it will gradually lay the cable flat and stretch it to the right. During this process, the roller 15 acts like a precise "flatter", gradually eliminating any unevenness such as wrinkles or bends that may exist in the cable, so that the cable presents an ideal flat state until the roller 15 moves to the right end of the cable, at which point the right end of the cable is also effectively fixed.
[0038] At this point, through the combined action of the pressure plate 9 and the roller 15, both ends of the cable are firmly fixed, and the entire cable is in a flat and stable state. At this time, the cable can be precisely punched by the punch of the punching machine. This operation process ensures that the cable can maintain a good state during the punching process, providing a strong guarantee for obtaining high-quality test samples.
[0039] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, alterations, additions or substitutions made by those skilled in the art within the scope of the present utility model should be protected by the present utility model.
