Description

Technical Field

[0001] The invention relates to the technical field of cable production, and in particular to a production device and a production process for a large-square flexible cable. Background Art

[0002] Large square flexible cable usually refers to a flexible cable with a larger cross-sectional area (cross-sectional diameter greater than 4.5mm). This type of cable has a higher current carrying capacity and lower voltage drop due to its larger conductor cross-sectional area, and is suitable for occasions that require transmission of large current or high power.

[0003] According to the Chinese patent application number CN202410555196.4: A cable performance testing device, the above patent sets a gear ring on the path of the cable bending test, so that the cable is continuously twisted back and forth while being bent, and the reciprocating motion of the clamping tube on the threaded rod drives the reciprocating stretching of the cable while twisting, so as to achieve multiple performance tests of the cable at the same time, thereby improving the comprehensiveness and persuasiveness of the test results. However, when the above patent performs bending detection on the cable, the cable can only be tested at one curvature, and the curvature of the cable detection cannot be changed, resulting in a reduction in the credibility of the cable bending detection.

[0004] At the same time, the above-mentioned patent is too complicated to implement when performing torsion detection on the cable, and because the cable protective layer has texture, the destructiveness of clockwise and counterclockwise twisting of the cable is different. The above-mentioned patent is difficult to perform comparative detection of clockwise and counterclockwise twisting of cables of the same model, resulting in reduced credibility of cable torsion detection. Summary of the invention

[0008] Furthermore, it also includes a placement box; the placement box is fixedly connected to the lower side of the second electric clamp; and a plurality of counterweight blocks are placed in the placement box.

[0009] Furthermore, the surface of each curved plate in contact with the first flexible cable and the second flexible cable is configured as a rough surface.

[0010] Furthermore, the first extrusion surface is set to be a rough surface; and the first extrusion portion is set to be a rough surface.

[0011] Furthermore, the second extrusion portion is configured as a rough surface; and the second extrusion surface is configured as a rough surface.

[0012] Furthermore, a triangular block is included; a triangular block is fixedly connected to one side of each curved plate away from the first flexible cable and the second flexible cable.

The force plate 6 is located on the right side of the first extrusion plate 5; a first extrusion portion 6001 is provided on the first pressure plate 6; a first limiting portion 6002 is provided on the first pressure plate 6; the first limiting portion 6002 is located in front of the first extrusion portion 6001; a first extruder 7 is connected to the rotating assembly; a second pressure plate 8 is connected to the workbench 1; a second limiting portion 8001 is provided on the second pressure plate 8; a second extrusion portion 8002 is provided on the second pressure plate 8; the second extrusion portion 8002 is located in front of the second limiting portion 8001; two second elastic members 14 symmetrical in upper and lower directions are connected to the workbench 1, and the second elastic member 14 is a spring telescopic rod; the telescopic ends of the two second elastic members 14 are commonly connected to the second extrusion plate 9, and the torsion detection of the second soft cable 11 is realized by the cooperation of the second pressure plate 8 and the second extrusion plate 9; the second extrusion plate 9 is located on the right side of the second pressure plate 8; a second extrusion surface 9001 is provided on the second extrusion plate 9; a second extruder 10 is connected to the rotating assembly; the second extruder 10 is located on the right side of the first extruder 7.

[0036] The rotating assembly includes a servo motor 101, a fixed plate 102, a first electric clamp 103, a second electric clamp 104 and a rotary head 105; the servo motor 101 is fixedly connected to the upper inner side of the workbench 1; the rotary head 105 is fixedly connected to the output end of the servo motor 101; the upper side of the rotary head 105 is fixedly connected to the fixed plate 102; the front side of the fixed plate 102 is fixedly connected to the first electric clamp 103; the lower front side of the workbench 1 is slidably connected to the second electric clamp 104.

[0037] It also includes a placement box 201 ; the placement box 201 is fixedly connected to the lower side of the second electric clamp 104 ; the placement box 201 is suspended in the air and does not contact the ground; and a plurality of counterweights are placed in the placement box 201 .

[0038] First, the staff will be the same specification of the first flexible cable 2 and the second flexible cable 11 as follows Figure 1 The method shown is placed on the front side of the workbench 1, so that the first flexible cable 2 and the second flexible cable 11 are located between the two bending plates 4, and then the first electric clamp 103 and the second electric clamp 104 are controlled to clamp the first flexible cable 2 and the second flexible cable 11, so as to fix the first flexible cable 2 and the second flexible cable 11, thereby achieving preparation before detection.

[0039] Then, the servo motor 101 is controlled to drive the rotating head 105 to perform alternating rotational motion (alternating rotational motion refers to the motion of an object repeatedly rotating in both positive and negative directions), thereby driving the fixed plate 102 and the first electric clamp 103 to perform alternating rotational motion, so that the first flexible cable 2 and the second flexible cable 11 are driven by the first electric clamp 103 to contact the bending plate 4 and be squeezed by the bending plate 4, so that the first flexible cable 2 and the second flexible cable 11 are deformed, and in the process of continued rotation, they gradually adhere to the above-mentioned bending plate 4, so that the upper ends of the first flexible cable 2 and the second flexible cable 11 gradually become bent, thereby realizing the bending detection of the first flexible cable 2 and the second flexible cable 11. It is worth noting that Before the staff starts the servo motor 101, the staff can control the driving member 12 to move one end of the bending plate 4 up and down, so that the rotating bending plate 4 rotates with the portion connected to the connecting plate 3 as the rotating point, thereby changing the angle of the bending plate 4. It is worth noting that the bending plate 4 is made of styrene-butadiene rubber material, so that when the first flexible cable 2 and the second flexible cable 11 squeeze the bending plate 4, the bending plate 4 will not be deformed, so that when the bending detection of the first flexible cable 2 and the second flexible cable 11 is performed, the bending angle of the first flexible cable 2 and the second flexible cable 11 is changed, so that the first flexible cable 2 and the second flexible cable 11 can be bent at different angles, thereby improving the credibility of the bending detection.

[0040] Subsequently, during the process of the fixed plate 102 and the first electric clamp 103 performing alternating rotational motions, due to the limitation of the first flexible cable 2 and the second flexible cable 11 by the bending plate 4, during the process of the first electric clamp 103 rotating to a horizontal state, the lengths of the first flexible cable 2 and the second flexible cable 11 are insufficient. Therefore, the first flexible cable 2 and the second flexible cable 11 will be subjected to the pulling force of the first electric clamp 103, so that the first flexible cable 2 and the second flexible cable 11 are pulled, thereby driving the second electric clamp 104 and the placement box 201 to move upwards. At this time, The first flexible cable 2 and the second flexible cable 11 are affected by the weight of the second electric clamp 104, the placement box 201 and the counterweight block in the placement box 201, so that the first flexible cable 2 and the second flexible cable 11 are pulled, thereby realizing a tensile test on the first flexible cable 2 and the second flexible cable 11. At the same time, the staff can adjust the tensile force on the first flexible cable 2 and the second flexible cable 11 by adjusting the number and weight of the counterweight blocks in the placement box 201, thereby realizing the detection of different tensile forces on the first flexible cable 2 and the second flexible cable 11 and improving the credibility of the detection.

[0041] Then, based on the view from the front to the back, when the servo motor 101 controls the fixed plate 102, the first electric clamp 103 and the rotating head 105 to rotate counterclockwise to a horizontal state, the first squeezer 7 will also rotate counterclockwise to a horizontal state with the rotating head 105, so that the first squeezer 7 squeezes the first squeezing plate 5 during the rotation process, so that the first elastic member 13 is stretched, so that the first squeezing plate 5 slides forward. Since the first flexible cable 2 is located between the first squeezing surface 5001 and the first squeezing portion 6001, and is affected by the first squeezing surface 5001 and the first squeezing portion 6001, the first squeezing plate 5 slides forward. Therefore, the first extrusion plate 5 slides forward to rub the first flexible cable 2, and the first flexible cable 2 rotates counterclockwise as viewed from top to bottom, thereby realizing the twisting of the first flexible cable 2 and completing the twisting detection of the first flexible cable 2, while the second flexible cable 11 is located between the first extrusion surface 5001 and the first limiting portion 6002, and is not squeezed between the first extrusion surface 5001 and the first limiting portion 6002. Therefore, the first extrusion plate 5 slides forward and does not cause the second flexible cable 11 to twist.

[0042] Subsequently, the servo motor 101 is controlled to drive the fixed plate 102, the first electric clamp 103 and the rotating head 105 to rotate to a vertical state, so that the first squeezer 7 is separated from the first squeezing plate 5, and the first elastic member 13 is gradually restored to its original state, thereby gradually restoring the first squeezing plate 5 to its original state. Subsequently, based on the view from the front to the back, when the servo motor 101 controls the fixed plate 102, the first electric clamp 103 and the rotating head 105 to rotate clockwise to a horizontal state, the second squeezer 10 will also rotate clockwise to a horizontal state with the rotating head 105. The second squeezer 10 squeezes the second squeeze plate 9 during the rotation process, stretches the second elastic member 14, and slides the second squeeze plate 9 forward. Since the second flexible cable 11 is located between the second squeeze portion 8002 and the second squeeze surface 9001 and is squeezed between the second squeeze portion 8002 and the second squeeze surface 9001, the second squeeze plate 9 slides forward to rub the second flexible cable 11, and the second flexible cable 11 rotates clockwise when viewed from top to bottom, thereby achieving the twisting of the second flexible cable 11, and completing The torsion detection of the second flexible cable 11 is carried out, while the first flexible cable 2 is located between the second limit portion 8001 and the second extrusion surface 9001 and is not squeezed between the second limit portion 8001 and the second extrusion surface 9001. Therefore, the second extrusion plate 9 slides forward and does not cause the first flexible cable 2 to twist. The present invention realizes the torsion of the first flexible cable 2 and the second flexible cable 11 in different directions. Subsequently, the servo motor 101 is controlled to drive the fixed plate 102, the first electric clamp 103 and the rotating head 105 to rotate to a vertical state, so that the second squeezer 10 is separated from the second extrusion plate 9, and the second elastic member 14 is gradually restored to its original state, thereby causing the second extrusion plate 9 to gradually restore to its original state. The present invention realizes the torsion detection comparison between the first flexible cable 2 and the second flexible cable 11 of the same specification and model (because the protective layers of the first flexible cable 2 and the second flexible cable 11 have textures, clockwise torsion and counterclockwise torsion have different damages to the protective layers of the first flexible cable 2 and the second flexible cable 11), thereby improving the comprehensiveness and persuasiveness of the torsion detection through comparative detection.

[0043] The surface of each bending plate 4 that contacts the first flexible cable 2 and the second flexible cable 11 is set to a rough surface; when the first flexible cable 2 and the second flexible cable 11 are pulled by the first electric clamp 103, the first flexible cable 2 and the second flexible cable 11 will move close to the bending plate 4, thereby rubbing the protective layers of the first flexible cable 2 and the second flexible cable 11 through the rough surface, thereby realizing friction detection of the protective layers of the first flexible cable 2 and the second flexible cable 11, increasing the detection content of the device, and improving the comprehensiveness of the detection.

[0044] The first extrusion surface 5001 is set as a rough surface; the first extrusion part 6001 is set as a rough surface; it is used to increase the friction between the first extrusion surface 5001 and the first extrusion part 6001 on the first flexible cable 2 to avoid slipping when the first extrusion surface 5001 rubs the first flexible cable 2.

[0045] The second extrusion portion 8002 is configured as a rough surface; the second extrusion surface 9001 is configured as a rough surface; this is used to increase the friction between the second extrusion portion 8002 and the second extrusion surface 9001 on the second flexible cable 11 to prevent the second flexible cable 11 from slipping when the second extrusion surface 9001 rubs the second flexible cable 11.

[0046] It also includes a triangular block 301; each bending plate 4 is fixedly connected to a triangular block 301 on one side away from the first flexible cable 2 and the second flexible cable 11; when the first electric clamp 103 gradually rotates to a horizontal state, the first flexible cable 2 and the second flexible cable 11 are squeezed by the edge of the triangular block 301, so that creases appear on the protective layers of the first flexible cable 2 and the second flexible cable 11, and the protective effect of the protective layers on the first flexible cable 2 and the second flexible cable 11 is further detected, thereby improving the credibility of the detection.

[0047] A triangular block 301 is detachably connected to one side of each bending plate 4 away from the first flexible cable 2 and the second flexible cable 11; different triangular blocks 301 are used to replace different triangular blocks 301, so that the triangular blocks 301 have different squeezing effects on the first flexible cable 2 and the second flexible cable 11, thereby improving the comprehensiveness of the detection of the first flexible cable 2 and the second flexible cable 11.

[0048] Example 3

[0049] On the basis of Example 1, Figure 1-Figure 6 As shown, the workbench 1 is slidably connected to each connecting plate 3; the workbench 1 is slidably connected to each first elastic member 13, and the first elastic member 13 is a spring telescopic rod; the workbench 1 is slidably connected to the first pressure plate 6; the workbench 1 is slidably connected to the second pressure plate 8; the workbench 1 is slidably connected to each second elastic member 14, and the second elastic member 14 is a spring telescopic rod; since the products produced by the factory have more than one model and specification, adaptation between products of different specifications and models is achieved, thereby improving the detection credibility. It is worth noting that the specifications and models of the first soft cable 2 and the second soft cable 11 always remain the same.

[0050] The production process of large square flexible cable includes the following steps:

[0051] S1: Loading, placing the first flexible cable 2 and the second flexible cable 11 on the workbench 1, and clamping and fixing them by the first electric clamp 103 and the second electric clamp 104;

[0052] S2: Bending detection, the rotating first flexible cable 2 and the second flexible cable 11 are bent by the bending plate 4 to achieve bending detection of the first flexible cable 2 and the second flexible cable 11;

[0053] S3: stretching test, by changing the number of weight blocks in the placement box 201, the stretching test of the first flexible cable 2 and the second flexible cable 11 is realized;

[0054] S4: Torsion detection, the first flexible cable 2 and the second flexible cable 11 are respectively squeezed and kneaded by the first squeezing plate 5 and the second squeezing plate 9 to achieve torsion detection of the first flexible cable 2 and the second flexible cable 11;

[0055] S5: Unloading: the staff removes the first flexible cable 2 and the second flexible cable 11 after the test.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
