Description
Technical Field
[0001] The invention belongs to the field of testing equipment, relates to the field of wire and cable testing, and specifically relates to a performance testing device for wire and cable production and a method of using the same. Background Art
[0002] Wires and cables are important components for transmitting electrical energy and signals, and their safety is of vital importance. Therefore, after production, their performance needs to be tested to ensure that no safety accidents occur due to quality problems during actual use.
[0003] Impact testing of wires and cables is to evaluate whether they can withstand various impacts and external forces in actual application scenarios and to ensure the integrity of their performance. It is also used to evaluate key performance indicators such as safety and durability of each batch of wires and cables to ensure the consistency and reliability of product quality.
[0004] At present, when impact tests are performed on cables, drop hammer tests are usually used. Conventional drop hammer test equipment is to set up a bracket on the test bench, and use ropes and pulleys to pull the hammer to move to adjust the height of the hammer. After releasing the rope, the hammer falls to impact the cable on the test bench. Although the structure is simple, the hammer is easily affected by the rope during the fall and swings, which affects the impact effect on the cable. With the development of technology, there is an improved solution that uses electromagnets to adsorb the hammer. Although this design avoids the interference of the rope on the hammer, manual intervention is still required when picking up the hammer, which affects the efficiency of use and reduces the degree of automation of the test. At the same time, the hammer structure widely used at this stage is fixed in weight, which means that if the weight of the hammer is to be adjusted according to different test requirements, the hammer must be replaced. This operation is time-consuming and labor-intensive, and lacks flexibility and convenience in test operations. Summary of the invention
[0005] In order to solve the technical problems of low automation, poor flexibility and convenience of cable impact test, the present invention provides a performance detection device for wire and cable production. The weight of the hammer is adjusted by increasing or decreasing the weight, and the hammer slides along the riser to facilitate picking up and releasing the impact cable, thereby improving the automation level, as well as the flexibility and convenience of use.
[0006] The technical solution adopted by the present invention is: to provide a performance detection device for wire and cable production and a method of using the same, including a test bench, and a base is horizontally movably arranged on the test bench, a hollow column is fixedly installed on the base, a connecting block and a driving block are lifted and lowered in the column by means of a lifting drive member, the connecting block protrudes from the front of the column, and a vertical pipe is fixedly installed, a hammer is slidably arranged in the vertical pipe, magnetic ears are installed on the upper left and right sides of the hammer, the magnetic ears pass through the vertical pipe respectively and are slidably connected to the vertical pipe, and support shafts are fixedly installed on the magnetic ears, and weights are detachably connected to the support shafts; connecting frames are installed on the left and right sides of the driving block, the connecting frames pass through the column respectively, and are slidably installed with the column, and the connecting frames are bent and extended to the top of the magnetic ears, and electromagnets that magnetically cooperate with the magnetic ears are fixedly installed on the connecting frames.
[0007] When conducting an impact test on a cable, lay the cable on the test bench and place it under the riser. Then add or remove weights from the support shaft to adjust the weight of the hammer. After the electromagnet on the connecting frame is energized to adsorb the magnetic lug on the hammer, the hammer is pulled upward to the test height. When the hammer moves upward, the base drives the riser to move horizontally synchronously along the test bench to select the impact point on the cable. After determining the impact position, the riser moves downward to contact the cable surface. Then the electromagnet is powered off to make the hammer lose traction and fall along the riser, thereby impacting the cable. After the impact is over, the connecting frame drives the electromagnet to move downward to re-adsorb the magnetic lug and pull the hammer to the test height. At the same time, the riser moves upward to break away from contact with the cable and is driven by the base to move horizontally. The impact position on the cable is selected again, and continuous impact tests are performed on the cable at multiple points to improve the test efficiency.
[0008] To further optimize the technical solution, a horizontal driving member is fixedly installed on the top surface of the test bench, and the horizontal driving member includes a transverse screw arranged on the top surface of the test bench, and a nut is matched on the transverse screw. The nut is fixedly installed on the base, and the base is assembled with the test bench for linear movement by means of a slide rail assembly.

[0015] The connecting block and the driving block are driven to rise and fall in the column by the engagement of the longitudinal lead screw and the nut. The column has operating openings on the front and left and right sides. The connecting block protrudes from the operating opening on the front of the column and is assembled with the vertical pipe to drive the pipe to rise and fall.

The sliding connection between the connecting frame and the operating opening ensures the stability of the driving block driven by the longitudinal lead screw, and after picking up the hammer, it drives the hammer to rise and fall to adjust the impact test height, thereby ensuring flexibility of use.

[0017] The guide assembly ensures the smoothness of the longitudinal screw driving the connecting block. The two ends of the guide rod are fixedly connected to the base and the column respectively, and the guide rod passes through the through hole on the connecting block to limit the movement posture of the connecting block and ensure the stability of the longitudinal screw driving.
[0018] To further optimize the technical solution, the power structure includes a matching drive motor and a gear box, the gear box is fixedly installed on the base, and the output shaft of the gear box is coaxially assembled with the longitudinal screw by means of a coupling.

[0024] A method for using a performance testing device for wire and cable production, comprising the following steps: S1. Cable laying: Lay the cable to be tested on the top surface of the test bench and adjust its position to the bottom of the riser; S2. Adjustment of hammer counterweight: by adding or removing weights from the connecting shaft of the magnetic lug, and ensuring that the weights on the two connecting shafts are exactly the same, the hammer counterweight can be accurately adjusted; S3. Hammer height setting: After the hammer weight is adjusted, the electromagnet on the connecting frame is used to absorb the magnetic lug to drive the hammer to move upward along the riser to the test height; S4. Impact position selection: When the hammer moves up along the column to the test height, the impact position of the hammer on the cable is selected by controlling the base to move horizontally along the test bench; S5. Adjustment of the riser position: After selecting the impact position, lower the riser position so that its bottom surface contacts the cable surface; S6, hammer release: After the hammer reaches the test height, the electromagnet is controlled to be powered off, so that it loses its magnetic attraction and is disconnected from the magnetic lug, thereby causing the hammer to lose its traction and fall along the riser to impact the cables under the riser; S7, hammer pick-up reset: After the impact test is completed, the electromagnet is energized again to generate magnetic attraction, the driving block drives the connecting frame to move downward and contact the magnetic lug, and the electromagnet attracts the magnetic lug again, thereby picking up the hammer and pulling the hammer upward to the test height; S8. Reselect the impact position: After completing a single impact test on the cable, the riser moves up to break away from the contact with the cable, and the base is controlled to drive the riser to move horizontally to reselect the impact position on the cable.
[0025] The beneficial effects of the present invention are: 1. When conducting impact test on cable, the weight of the hammer is adjusted by adding or removing weights on the connecting shaft, and the magnetic attraction of the magnetic lug is attracted by the electromagnet on the connecting frame, and the longitudinal lead screw drives the hammer to move up and down, so as to adjust the impact strength on the cable, improve the flexibility and diversity of cable impact test, and ensure the test efficiency and test effect; 2. After selecting the impact position for the cable, move the riser down to contact the cable surface to determine the impact point. After the hammer is released, it falls along the riser to impact the cable, ensuring accurate transmission of the impact force and improving the accuracy of the test. The hammer slides linearly in the riser with the help of the guide rail assembly, which is convenient for picking up after the impact. It is easy and flexible to use. 3. When the electromagnet is energized, the hammer generates magnetic attraction to adsorb the magnetic hook, so as to pick up the hammer and lift it up and down along the column. When the electromagnet is powered off, the magnetic attraction disappears, causing the magnetic hook and the hammer to lose traction and fall due to gravity, impacting the cable. It has a simple structure, stable operation and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

A horizontal driving member is fixedly installed on the top surface of the test bench 1, and the horizontal driving member drives the base 2 to move horizontally along the top surface of the test bench 1. The horizontal driving member includes a transverse lead screw 9 arranged on the top surface of the test bench 1, and a nut 10 is matched on the transverse lead screw 9. The nut 10 is fixedly installed with the base 2, and in order to ensure the smoothness of the linear movement of the base 2 driven by the meshing of the transverse lead screw 9 and the nut 10, the base 2 is assembled with the test bench 1 by means of a slide rail 11 assembly; Please see attached Figure 1-4 The slide rail 11 assembly includes a slide rail 11 fixedly mounted on the top surface of the test bench 1 and a slider 12 matched with the slide rail 11. The slider 12 is fixedly mounted on the base 2. Two sets of slide rail 11 assemblies can be selected, so that they are distributed front and back on the front and back sides of the transverse lead screw 9 to ensure the stability of the support of the base 2 and reduce the driving load of the transverse lead screw 9 driving the base 2 to move. The transverse lead screw 9 can be driven by assembling a motor and configuring a hand wheel, etc., which is flexible and diverse to use. Please see attached Figure 1-6 A hollow column 3 is fixedly mounted on the base 2. The bottom surface of the hollow column 3 is open. After being plugged into the base 2, it is fixed by bolts. A limit strip is arranged at the bottom of the inner wall of the column 3. The limit strip abuts against the top surface of the base 2. The limit strip supports the column 3, reduces the fixing load of the bolt, and ensures the fixing strength of the bolt on the column 3. Please see attached Figure 5 , Attachment Figure 7Two lifting drive members are arranged in the front and rear of the column 3, and the two lifting drive members are respectively fixedly installed on the base 2. The two lifting drive members respectively drive the connection block 4 and the driving block 5 in the column 3 to rise and fall. The lifting drive member includes a power structure fixed on the base 2. The power structure can select a matching driving motor 15 and a gear box 16. The gear box 16 is fixedly installed on the base 2. The output shaft of the gear box 16 is vertically upward and is coaxially assembled with the longitudinal screw 13 by means of a coupling. The top of the longitudinal screw 13 is rotatably installed with the top surface of the column 3, so as to drive the longitudinal screw 13 to rotate stably and reliably. Please see attached Figure 5 , Attachment Figure 7 , the longitudinal lead screw 13 is equipped with a nut 10, the nut 10 is respectively assembled with the connection block 4 and the drive block 5, the front of the column 3 is provided with an operation port 301, the connection block 4 protrudes from the front of the column 3 through the operation port 301, and is fixedly installed with the stand pipe 6, and the connection block 4 is assembled with the column 3 by means of a guide assembly, and the guide assembly ensures the stability of the longitudinal lead screw 13 and the nut 10 engaging to drive the stand pipe 6 to rise and fall; Please see attached Figure 5 , Attachment Figure 7 , Attachment Figure 8 The guide assembly includes a through hole 401 provided on the connection block 4 and a guide rod 14 provided in the through hole 401. Both ends of the guide rod 14 respectively pass through the through holes 401 and are fixedly installed with the base 2 and the column 3 respectively. The connection block 4 is slidably connected with the guide rod 14 through the through hole 401. The guide rod 14 restricts the connection block 4 so that the longitudinal lead screw 13 is engaged with the nut 10, so that the connection block 4 can be smoothly lifted and lowered. In order to ensure the reliability of driving the stand pipe 6, a connection block 4 can be additionally provided on the guide rod 14 and matched with the longitudinal lead screw 13, so as to enhance the support strength of the stand pipe 6 and ensure the performance. Please see attached Figure 1 , Attachment Figure 2 , Attachment Fig. 9 A hammer 7 is slidably arranged in the riser 6. The hammer 7 consists of a hammer body 701 and a hammer head 702. The hammer head 702 can be connected to the bottom of the hammer body 701 by means of a mortise and tenon structure. The operation is simple and reliable. The replaceable setting of the hammer head 702 is convenient for disassembly and maintenance, and it is convenient to replace cone heads of different shapes according to test requirements, thereby ensuring test flexibility. The hammer body 701 is slidably arranged in the riser 6 by means of a guide rail 17 assembly. The guide rail 17 assembly includes a matching guide rail 17 and a slider 12. The guide rail 17 is circumferentially distributed on the inner wall of the riser 6 and is fixedly installed with the riser 6, while the slider 12 is fixedly installed with the hammer body 701. The guide rail 17 and the slider 12 ensure the smoothness of the sliding of the hammer 7. Please see attached Figure 1 , Attachment Figure 2 , Attachment Fig.10Magnetic ears 8 are fixedly installed on the top of the left and right sides of the hammer body 701 of the hammer 7. The magnetic ears 8 pass through the left and right sides of the vertical pipe 6 respectively and are slidably connected with the vertical pipe 6. The left and right sides of the vertical pipe 6 can provide space for the sliding of the magnetic ears 8 by opening vertical strips, and the use effect of the vertical pipe 6 is not affected. The magnetic ears 8 are constrained in the vertical strips of the vertical pipe 6 to prevent the hammer 7 from slipping off the vertical pipe 6 at will, ensuring the reliability of use. The magnetic ears 8 are fixedly provided with support shafts 801. The support shaft 801 is detachably connected with a weight 802. By adding or removing the weight 802 on the support shaft 801, the weight of the hammer 7 can be adjusted to adapt to the test scene, ensuring the flexibility of the hammer 7 in the cable impact test. A clamp or a threaded connection nut can be set on the support shaft 801 to prevent the weight 802 from falling off and shaking. At the same time, a limit point is set on the support shaft 801 to prevent the weight 802 from contacting the riser 6 and interfering with the movement of the hammer 7, thereby ensuring the reliability of the test. Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 , Attachment Fig.11 When picking up the punch 7 and adjusting its use height, the left and right sides of the driving block 5 are fixedly installed with connecting frames 501, and the left and right sides of the column 3 are also provided with operating ports 301. The connecting frames 501 pass through the column 3 through the operating ports 301 respectively, and the sliding connection between the connecting frame 501 and the operating port 301 constrains the movement state of the driving block 5, ensuring that the longitudinal screw 13 is meshed with the nut 10 to control the stability of the lifting and lowering operation of the driving block 5, and the connecting frame 501 passing through the column 3 is bent and extended to the top of the magnetic suction ear 8. At the same time, the connecting frame 501 is fixedly installed with an electromagnet 502 that magnetically cooperates with the magnetic suction ear 8. After the electromagnet 502 is energized, it is magnetically attracted to the magnetic suction ear 8, and the driving part is lifted and lowered along the longitudinal screw 13 to adjust the position of the punch 7. After the electromagnet 502 is powered off, the magnetic suction ear 8 loses its adsorption, so that the punch 7 loses its restriction and falls along the riser 6, and the cable below it is subjected to an impact test. The operation is simple, the automation level is improved, and the test efficiency is improved; The working principle of the performance testing device for wire and cable production is as follows: after laying the cable to be tested on the test bench 1, add or subtract the weight 802 to the connecting shaft of the magnetic lug 8 according to the test requirements, and ensure that the weights 802 on the two connecting shafts are consistent, and then use a nut or a clamp to lock the weight 802 to accurately adjust the weight of the hammer 7. Next, the electromagnet 502 on the connecting frame 501 is energized to generate a magnetic attraction force to tightly adsorb the magnetic lug 8, and at the same time, the drive block 5 moves upward along the longitudinal lead screw 13 to pull the hammer 7 upward to the test height. While the hammer 7 moves upward, the transverse lead screw 9 engages with the nut 10 to drive the base 2 to move horizontally along the test bench 1 to select the impact test point for the cable. After determining the point, the height of the riser 6 is lowered, and the bottom surface of the riser 6 is brought into contact with the surface of the cable to determine the impact point, ensure the accurate transmission of the impact force, and improve the accuracy of the test. Then the electromagnet 502 is powered off and loses its magnetic attraction, releasing the attraction on the magnetic lug 8, causing the hammer 7 to lose its restraint and fall along the riser 6, impacting the cable under the riser 6, which is easy to operate. After the impact on the cable is completed, the electromagnet 502 is powered on to generate magnetic attraction, and the drive block 5 drives the connecting frame 501 to move down along the column 3, and after contacting the magnetic lug 8, it adsorbs the magnetic lug 8 again and pulls the hammer 7 upward to the test height. Then the riser 6 is moved up to break away from the contact with the cable so as to reselect the impact point on the cable. This cycle can be repeated to perform continuous impact tests on multiple points of the cable, which is easy to operate and improves the test efficiency.
[0030] The method for using the performance detection device for wire and cable production comprises the following steps: S1. Cable laying: Lay the cable to be tested on the top surface of the test bench 1 and adjust its position to below the riser 6; S2. Adjusting the counterweight of the hammer: by adding or removing weights 802 on the connecting shaft of the magnetic lug 8 and ensuring that the weights 802 on the two connecting shafts are completely consistent, the counterweight of the hammer 7 is accurately adjusted; S3, hammer height setting: after the weight adjustment of the hammer 7 is completed, the electromagnet 502 on the connecting frame 501 is used to attract the magnetic lug 8 to drive the hammer 7 to move upward along the riser 6 to the test height; S4, impact position selection: when the hammer 7 moves up along the column 3 to the test height, the impact position of the hammer 7 on the cable is selected by controlling the base 2 to move horizontally along the test bench 1; S5. Adjustment of the riser position: After selecting the impact position, lower the riser 6 so that its bottom surface contacts the cable surface; S6, hammer release: after the hammer 7 reaches the test height, the electromagnet 502 is controlled to be powered off, so that it loses its magnetic attraction and is disconnected from the magnetic lug 8, so that the hammer 7 loses its traction and falls along the riser 6 to impact the cables under the riser 6; S7, hammer pick-up reset: after the impact test is completed, the electromagnet 502 is powered on again to generate magnetic attraction, the driving block 5 drives the connecting frame 501 to move downward and contact the magnetic attraction lug 8, the electromagnet 502 attracts the magnetic attraction lug 8 again, thereby picking up the hammer 7 and pulling the hammer 7 upward to the test height; S8. Reselect the impact position: After completing a single impact test on the cable, the riser 6 moves upward to break away from the contact with the cable, and the base 2 is controlled to drive the riser 6 to move horizontally, and the impact position on the cable is reselected.

9. A performance testing device for electric wire and cable production according to claim 8, characterized in that: The guide rail assembly comprises a guide rail (17) and a slider (12) which are arranged in a matching manner. The guide rail (17) is circumferentially distributed on the inner wall of the vertical pipe (6) and is fixedly installed on the vertical pipe (6), and the slider (12) is fixedly installed on the hammer body (701).
10. A method for using a performance testing device for producing wires and cables, according to any one of claims 1 to 9, characterized in that: The steps include: S1. Cable laying: Lay the cable to be tested on the top surface of the test bench (1) and adjust its position to below the riser (6); S2. Adjusting the counterweight of the hammer: by adding or removing weights (802) on the connecting shaft of the magnetic hook (8), and ensuring that the weights (802) on the two connecting shafts are completely consistent, the counterweight of the hammer (7) is accurately adjusted; S3, hammer height setting: after the weight of the hammer (7) is adjusted, the electromagnet (502) on the connecting frame (501) is used to attract the magnetic hook (8) to drive the hammer (7) to move upward along the vertical pipe (6) to the test height; S4, impact position selection: when the hammer (7) moves upward along the column (3) to the test height, the impact position of the hammer (7) on the cable is selected by controlling the base (2) to move horizontally along the test bench (1); S5, stand pipe position adjustment: after selecting the impact position, lower the stand pipe (6) so that its bottom surface contacts the cable surface; S6, hammer release: after the hammer (7) reaches the test height, the electromagnet (502) is controlled to be powered off, so that it loses its magnetic attraction and is disconnected from the magnetic attraction lug (8), thereby causing the hammer (7) to lose its traction and fall along the riser (6) to impact the cables under the riser (6); S7, hammer pick-up and reset: after the impact test is completed, the electromagnet (502) is powered on again to generate magnetic attraction, the driving block (5) drives the connecting frame (501) to move downward and contact the magnetic attraction lug (8), and the electromagnet (502) attracts the magnetic attraction lug (8) again, thereby picking up the hammer (7) and pulling the hammer (7) upward to the test height; S8, reselecting the impact position: After completing a single impact test on the cable, the riser (6) moves upward to break away from the contact with the cable, and the base (2) is controlled to drive the riser (6) to move horizontally, and the impact position on the cable is reselected.
