[0002] Cables are an indispensable infrastructure in modern society, used to transmit power, data, and communication signals. Their performance, reliability, and safety are of utmost importance, and these aspects are directly influenced by the quality and performance of the insulating materials. Therefore, the cable manufacturing industry needs effective methods to evaluate the performance of insulating materials, ensuring that they meet the requirements of various applications.

[0003] Cable sheaths are an important component of cables, and their performance directly affects the insulation performance, electrical performance, and durability of the cable. To evaluate the performance of insulating materials, the cable manufacturing industry usually performs tensile tests, which require the preparation of specific-shaped dumbbell specimens. Tensile tests can measure key performance indicators such as tensile strength, elastic modulus, and breaking strain of the insulating material. Therefore, the preparation of high-quality dumbbell specimens is a critical step in the cable manufacturing industry.

[0004] Traditionally, the preparation of dumbbell specimens is a tedious process that requires a lot of manual operations. These operations include measuring, cutting, and punching the insulating material, which not only takes time and effort, but also easily introduces human errors, thereby affecting the accuracy of the test results. Therefore, there is an urgent need in the cable manufacturing industry to seek a more efficient, accurate, and automated method for preparing dumbbell specimens.

[0060] The embrace and clamp mechanism 2 is arranged on the rack 1, and is used for fixing the cable to be sliced, and includes an embrace and clamp platform 21, which is fixed to the surface of the rack 1 by bolts, the embrace and clamp platform 21 is a plate structure, a rectangular slot is formed in the embrace and clamp platform 21, a supporting claw 221 is arranged on the embrace and clamp platform 21 in a lifting mode through the rectangular slot, a lifting mechanism 23 is connected with the supporting claw 221 and arranged in the rack 1 body below the embrace and clamp platform 21, a clamping claw 222 is symmetrically arranged on both sides of the supporting claw 221, the clamping claw 222 is driven by a sliding module 24, the clamping claws 222 on both sides move relatively, that is, the clamping claws 222 on both sides can simultaneously move close to or away from the supporting claw 221, in the embodiment, one supporting claw 221 and two clamping claws 222 on both sides form one embrace and clamp group 22, the embrace and clamp group 22 can be provided with one group or multiple groups according to the slicing length, the supporting claw 221 supports the cable from the bottom in the cable axial direction, the clamping claws 222 clamp the cable from both sides, the cable is clamped from three sides, the cable is fixed, the slicing mechanism 3 is convenient to slice the cable from the upper part of the cable, the cable does not deviate during the cutting process, and the cutting process is more stable.

[0061] The slicing mechanism 3 is arranged above the embrace and clamp mechanism 2, and cuts the cable fixed on the embrace and clamp mechanism 2 through reciprocating motion, in the embodiment, the slicing mechanism 3 is arranged above the embrace and clamp mechanism 2 through an external moving mechanism (not shown in the figure), the external moving mechanism can be a moving module, the slicing mechanism 3 is fixed on the sliding block of the moving module, so as to reciprocate, the external moving mechanism can also be a telescopic cylinder with an output end connected to the slicing mechanism 3, the telescopic cylinder drives the slicing mechanism 3 to reciprocate along a predetermined track, the slicing mechanism 3 reciprocates along the cable axial direction above the supporting claw 221; the slicing mechanism 3 includes a cylinder support 31, the cylinder support 31 is connected with the external moving mechanism, a cutting knife 34 is arranged on the cylinder support 31 through a cylinder to cut the cable, the cutting knife 34 includes a knife seat 341, the knife seat 341 is used for fixing a slicing knife 342 on the cylinder support 31, a cutting knife pressing plate 343 is arranged on the slicing knife 342, the cutting knife pressing plate 343 is used for fixing the slicing knife 342, so as to prevent the slicing knife 342 from deviating during slicing, the cutting edge of the slicing knife 342 is arranged to be inclined downward, which is beneficial to cutting the cable under the pressure of the cylinder.

[0062] The punching mechanism 4 is mounted on the frame 1 and located at the rear end of the clamping mechanism 2. It is used to punch dumbbell test pieces from the slices cut by the slicing mechanism 3. The punching mechanism 4 includes a punching bracket 41, which is fixed to the surface of the frame 1 by bolts. A punching cylinder 42 is mounted on the punching bracket 41. The output end of the punching cylinder 42 is vertically downward. The output end of the punching cylinder 42 is connected to a die head 44 through a punching die mounting block 43. When the slice is placed on the punching platform below the die head 44, the punching cylinder 42 is activated, and the die head 44 presses down to punch the slice, thereby forming dumbbell test pieces. Multiple dumbbell test pieces can be punched from each slice, which improves the utilization rate of cable sheath slices.

[0063] To achieve continuous slicing and punching operations, this embodiment also includes a movable clamping mechanism 5, mounted on the frame 1, used to move the cut slices from the clamping mechanism 2 to the punching mechanism 4. The movable clamping mechanism 5 includes a horizontal moving module 51 mounted in the parallel direction of the clamping mechanism 2 and the punching mechanism 4. The horizontal moving module 51 is mounted on the surface of the frame 1, and its stroke covers both the clamping mechanism 2 and the punching mechanism 4. The horizontal moving module 51 is driven by a motor, which drives the slider on the horizontal moving module 51 to reciprocate. The slicing fixture 52 is fixed to the slider by a support plate 521, thereby enabling it to reciprocate between the clamping mechanism 2 and the punching mechanism 4, thus moving the slices. In this embodiment, the clamping mechanism 2 and the punching mechanism 4 are offset to ensure sufficient space for cable placement. The slicing fixture 52 includes a support plate 521 fixed on the horizontal moving module 51. The support plate 521 is provided with a fixture frame 522. The fixture frame 522 is provided with a telescopic cylinder 523. The output end of the telescopic cylinder 523 is provided with a gripper 524 for gripping the slice. The gripper 524 includes two upper and lower teeth. The two teeth are pneumatically clamped to achieve the gripping of the slice. During cutting, the gripper 524 clamps the slice and pulls it in the opposite direction of cutting. After cutting, the gripper 524 moves the slice to the punching mechanism 4.

[0064] The working principle of the cable sheath cutting and punching device provided in this embodiment is as follows:

[0065] First, the cable to be sliced ​​is placed on the claw 221 by manual or robotic arm. According to the cable specifications, the claw 221 is lifted to a suitable height, and at the same time, the clamping claws 222 on both sides clamp the cable in the direction of the cable, clamping the cable from three sides to fix the cable, so that the slicing mechanism 3 can slice the cable from the top of the cable.

[0066] Then, adjust the cutter 34 to a suitable height so that its slicing blade 342 is against the surface of the cable sheath. Start the external moving mechanism to drive the cutter 34 to slice the cable sheath. The slice is cut from the side of the slicing blade 342 away from the blade. At this time, the clamp 524 is extended to the slicing position by the telescopic cylinder 523. The clamp 524 clamps the slice and pulls it in the opposite direction of the cutting, which improves the smoothness of the slicing.

[0067] At this time, the telescopic cylinder 523 is reset, the horizontal moving module 51 is started to drive the slicing fixture 52 to move below the die head 44, and the punching cylinder 42 is started to punch the first position of the slice to produce a dumbbell test piece. After one punching is completed, the horizontal moving module 51 continues to drive the slicing fixture 52 to move. The punching mechanism 4 can punch the second position, third position, etc. of the subsequent slices, so as to complete the production of multiple dumbbell test pieces in one cut.

[0068] Example 2

[0069] This embodiment 2 is based on embodiment 1. By optimizing the structure of the support claw 221 and the clamping claw 222, and coordinating with the installation method of the cutter 34, the stability of cable fixing and the uniformity of the slice are improved. Specifically:

[0070] like Figures 2-7 As shown, the claw 221 has first comb teeth 2211 extending horizontally to both sides on its edge, and a V-groove 2212 is opened in the middle of the claw 221. When the cable diameter is small, the V-groove 2212 can be used to support the cable. When the cable diameter is large, the first comb teeth 2211 are used to support the cable, making the cable placement more stable. The bottom part of the cable is embedded in the V-groove 2212, and the end of the V-groove 2212 plays a limiting role for the cable. This design allows the claw 221 to adapt to cables of different specifications and sizes, improving the versatility of this device. In this embodiment, the gripper 222 is a plate-like structure with a second comb tooth 2221 that cooperates with the first comb tooth 2211. The second comb tooth 2221 is located on the upper part of the plate-like structure. The first comb tooth 2211 and the second comb tooth 2221 are staggered. When the diameter of the clamped cable is small, when the gripper 221 rises and the gripper 222 moves towards each other, the first comb tooth 2211 and the second comb tooth 2221 can intersect, and the second comb tooth 2221 passes through the gap of the first comb tooth 2211 to hold the cable. When the diameter of the clamped cable is large, when the gripper 221 rises and the gripper 222 moves towards each other, the first comb tooth 2211 and the second comb tooth 2221 will not interfere. The plate-like structure on the inner side of the gripper 222 directly clamps the side of the cable. Similarly, the cooperation between the gripper 222 and the gripper 221 can also adapt to cables of different specifications and sizes, improving the versatility of this device.

[0071] In other embodiments, a stop 25 is provided at the end of the clamping platform 21 away from the slicing mechanism 3. The stop 25 is located at the end of the cutting operation stroke. That is, when one end of the cable abuts against the stop 25, the cable cannot continue to move. The length of the slice obtained by cutting is fixed to the distance from the initial position of the cutter 34 to the stop 25, which prevents the cable from moving along its axial direction during the cutting process and ensures the stability of the cutting.

[0072] Furthermore, the cutter 34 is fixed to the cylinder bracket 31 by a floating cylinder 32. The output end of the floating cylinder 32 is connected to a floating plate 33, which slides vertically on the cylinder bracket 31 via a guide rail. Under the action of the floating cylinder 32, the cutter 34 slides vertically on the cylinder bracket 31. During the cutting operation, a fixed pressure value is set for the floating cylinder 32, so that the depth to which the cutter 34 cuts into the cable remains constant, ensuring that the thickness of the cut slices is consistent, thereby ensuring the quality of subsequent dumbbell test piece production. A guide plate 345 is also covered above the cutter pressure plate 343. The guide plate 345 can press down the cut slices, and together with the slice clamp 52, prevent the slices from curling, so as not to affect the subsequent punching operation.

[0073] Example 3

[0074] This embodiment 3 is a cable sheath slicing and punching device developed based on embodiment 1 or embodiment 2, such as... Figures 8-11 As shown, by setting a connecting rod 46 structure between the tilting hopper 45 and the die mounting block 43, the demolding and material receiving can be carried out simultaneously, thereby improving the working efficiency of the punching mechanism 4.

[0075] Specifically, a tilting hopper 45 is provided between the blanking bracket 41 and the die mounting block 43. One end of the tilting hopper 45 is hinged to the blanking bracket 41, and the other end is connected to the die mounting block 43 through two symmetrical connecting rods 46. Limiting posts 48 are provided on both sides of the die mounting block 43. A slotted hole 47 is opened on the side of the connecting rod 46 connected to the die mounting block 43. One end of the connecting rod 46 is axially connected to both sides of the tilting hopper 45, and the other end of the connecting rod 46 is connected to the die mounting block 43 through the limiting post 48. The limiting post 48 is slidably limited within the slotted hole 47. Please refer to [reference needed]. Figure 8 , Figure 10 During blanking, the tilting hopper 45 rotates downwards under its own weight until its outlet is vertically downwards. At this point, the tilting hopper 45 is positioned between the die mounting block 43 and the blanking bracket 41, and the tilting hopper 45 will not affect the blanking operation of the die head 44. Please refer to [reference needed]. Figure 9 , Figure 11After one punching cycle, when the punching cylinder 42 resets, the die mounting block 43 moves upward, and the limit posts 48 on both sides slide within the slot 47. When the slot 47 moves away from the side of the tilting hopper 45, the limit posts 48 can pull the connecting rod to follow the die mounting block 43 upward, thereby causing the tilting hopper 45, which is connected to the punching bracket 41, to rotate upward and catch the dumbbell test piece falling from the die head 44. The dumbbell test piece slides out from the discharge port of the tilting hopper 45 and falls into the discharge bucket, completing the automatic collection of dumbbell test pieces. By setting a connecting rod 46 structure between the tilting hopper 45 and the die mounting block 43, demolding and material receiving are carried out simultaneously. The simple linkage structure improves the punching speed, eliminates manual intervention, and ensures the consistency and accuracy of the punched test pieces, thereby solving the problems of low efficiency caused by traditional decentralized processes, low safety factor caused by manual intervention, and inconsistent test pieces. In some embodiments, a baffle plate 49 may be provided on the frame 1 opposite the punching mechanism 4 to prevent dumbbell test pieces that slide off the tilting hopper 45 from falling onto the frame 1 or the moving clamping mechanism 5.

[0076] Example 4

[0077] This embodiment 4 is a cable sheath slicing and punching device developed based on embodiment 1, embodiment 2, or embodiment 3, such as... Figure 1 , Figure 12 As shown, by adding a correction mechanism 6 between the clamping mechanism 2 and the punching mechanism 4, the cut slices are corrected to ensure the punching quality of the dumbbell test pieces.

[0078] Please refer to Figure 1 , Figure 12 The correction mechanism 6 includes a lifting cylinder 61 mounted on the frame 1. The lifting cylinder 61 serves to avoid the slicing clamp 52. That is, when the cutting operation is performed, the gripper 524 needs to clamp the slice and pull it in the opposite direction of cutting. At this time, in order to prevent the correction platform 64 from interfering with the slicing clamp 52, the correction platform 64 needs to be lowered by the lifting cylinder 61.

[0079] Furthermore, the output end of the lifting cylinder 61 is vertically upward, and a fixing block 62 is provided at the end of the output end. The fixing block 62 is a horizontally placed square aluminum profile. A correction platform 64 is provided above the fixing block 62. The bottom of the correction platform 64 is hinged to the fixing block 62 through a pad 66. Specifically, the hinge 63 is provided on the side of the fixing block 62, and the pad 66 is higher than the surface of the fixing block 62, ensuring that the correction platform 64 can freely change its angle on the fixing block 62. When the correction platform 64 rotates to one side of the fixing block 62, the upper surface of the fixing block 62 limits the correction platform 64 and prevents the correction platform from continuing to rotate. A pneumatic rod 65 is provided at the bottom of the correction platform 64. The output end is vertically upward and fixed to the bottom of the correction platform 64. It is used to push the correction platform 64 to change its angle. The correction platform 64 has a baffle 67 on the side away from the horizontal moving module 51. When the moving clamping mechanism 5 clamps the slice and passes the correction platform 64, the correction platform 64 moves upward under the action of the lifting cylinder 61. Then the clamp 524 is released, so that the slice falls on the correction platform 64. The pneumatic rod 65 retracts, and the slice moves closer to the baffle 67 under the action of gravity until one side of the slice is completely attached to the baffle 67, thus completing the correction of the slice. This ensures that the angle of the slice entering the punching mechanism 4 is correct, thereby improving the punching quality of the dumbbell test piece.
