[0002] Communication cables are used to transmit telephone, telegraph, fax documents, television and radio programs, data and other electrical signals. They are made of one or more mutually insulated wires twisted together. Compared with overhead wires, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less impact from natural conditions and external interference.

[0003] During the cable production and preparation process, a protective layer is formed on the outer wall of the cable core through an extruder, and then a subsequent wrapping and coating process is carried out. However, the existing processing equipment often does not have corresponding pre-treatment methods such as cooling and drying. The cable is easily deformed or cracked by traction, thereby affecting the compression and high temperature resistance of the cable core. In addition, the prepared cable needs to be wound onto a winding rack for subsequent sales and transportation. However, the winding machine generally winds in a single direction, and the winding surface is too concentrated. It cannot adapt to the conveying guidance of cables of different sizes, affecting the safe transportation of the device.

[0044] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] According to an embodiment of the present invention, there is provided an intelligent stamping device and a stamping method for vehicle parts.

[0046] Reference Manual Attached Figure 1 and attached Figure 2A pressure-resistant and high-temperature resistant communication cable comprises a cable core 1 formed by twisting at least two conductors, the cable core 1 is distributed in a triangular shape and the outer surface is connected to a filling layer 3 through a protective layer 2, and an elastomer 4 is connected to the center of the filling layer 3, a triangular spacer 5 is integrally formed on the elastomer 4 and connected, and the outer wall of the triangular spacer 5 is provided with an insulating layer 6 connected to the filling layer 3; wherein the filling layer 3 is processed and formed by passing through a conveying mechanism 7, a cooling mechanism 8, a drying mechanism 9, a coating mechanism 10 and a winding mechanism 11 on a workbench in sequence.

[0047] Specifically, the conveying mechanism 7 includes a first motor 12 on the workbench, the output shaft of the first motor 12 extends to the first rotating tooth 13, the outer wall of the first rotating tooth 13 is meshed with the second rotating tooth 14, the first rotating tooth 13 and the second rotating tooth 14 are correspondingly connected to the first guide roller 15 and the second guide roller 16; wherein the first guide roller 15 and the second guide roller 16 maintain synchronous reverse rotation, and are both used to carry and convey cables.

[0048] The conveying mechanism 7 is driven and connected by the first motor 12, so that the first guide roller 15 and the second guide roller 16 can be connected in reverse transmission by means of the transmission effect of the first rotating tooth 13 and the second rotating tooth 14. The conveying cavity formed between the two can ensure the effective and stable conveying of the cable. At the same time, the transmission ratio between the first rotating tooth 13 and the second rotating tooth 14 is maintained at 1:1, so that the rotation speeds of the two can be kept consistent, so that the cable can be smoothly conveyed when passing through the conveying cavity.

[0049] refer to Figure 1 and Figure 6 The cooling mechanism 8 includes a cooling box 17 connected to the cable, and the inner wall of the cooling box 17 is provided with heat transfer rollers 18 which are staggered up and down. The outer wall of the cooling box 17 is provided with a heat sink 19 which is compatible with it. A rectangular groove 20 is arranged on the inner wall of the cooling box 17 between the heat sink 19 and the heat transfer rollers 18, and the rectangular groove 20 is filled with water.

[0050] Specifically, the rectangular groove 20 in the cooling box 17 is filled with water, and the water can conduct heat quickly. At the same time, the heat transfer roller 18 can not only serve the purpose of conveying and guiding, but also transfer the heat on the cable to the water and the heat dissipation plate 19. The heat on the cable can be discharged in time through structural coordination, and the up and down staggered manner of the heat transfer roller 18 effectively increases the heat dissipation time and area, thereby improving the heat dissipation efficiency.

[0051] By setting up the cooling mechanism 8, the filling layer 3 in the cable can be cooled quickly. The heat transfer rollers 18 arranged alternately up and down can extend the conveying area and time. By utilizing the large specific heat capacity of water and cooperating with the heat sink 19, the heat on the heat transfer rollers 18 can be dissipated through the water and the heat sink 19, thereby achieving the purpose of rapid cooling and improving the cooling and molding effect of the filling layer 3 on the cable core 1.

[0052] refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 The drying mechanism 9 includes a drying box 21 placed on the top of the workbench, a fan 22 placed at the air inlet is fixedly installed on one end of the outer wall of the drying box 21, and an air outlet placed on the drying box 21 is connected to the other end, and a second motor 23 is fixedly installed on the drying box 21, and the output shaft of the second motor 23 extends to the third rotating tooth 24, and the first gear plate 25 and the second gear plate 26 are meshed and driven at both ends of the outer wall of the third rotating tooth 24, and the first gear plate 25 and the second gear plate 26 are correspondingly connected to an upper bracket 27 and a lower bracket 28 placed on the inner wall of the drying box 21; wherein, the upper bracket 27 and the lower bracket 28 are correspondingly connected at both ends to an upper arc-shaped pressing plate 29 and a lower arc-shaped pressing plate 30, and absorbent cotton 31 is adhesively fixed on the outer walls of the upper arc-shaped pressing plate 29 and the lower arc-shaped pressing plate 30 near the feeding port and the discharging port of the drying box 21.

[0053] The lower arc-shaped pressing plate 30 is provided with a guide hole 32 running through the inside thereof. The drying mechanism 9 not only dries the cable by air drying, but also absorbs and dries the cable through the absorbent cotton 31 on the inlet and outlet when the cable passes through the drying box 21, thereby achieving the purpose of cable drying. At the same time, due to the long-term absorption and drying of the absorbent cotton 31, its adsorption capacity will be significantly reduced. Therefore, the patent sets a transmission mechanism, which can squeeze out the moisture in the absorbent cotton 31 by pressing, thereby ensuring the adsorption capacity of the absorbent cotton 31. The working principle of the transmission mechanism is as follows:

[0054] After starting, the second motor 23 will drive the third gear 24 to rotate. Through the meshing transmission of the third gear 24 with the first gear plate 25 and the second gear plate 26, the third gear 24 and the first gear plate 25 and the second gear plate 26 move up and down in opposite directions, thereby correspondingly driving the upper arc pressure plate 29 and the lower arc pressure plate 30 at both ends to clamp or separate with each other. In this way, the moisture in the absorbent cotton 31 can be squeezed out during the process of clamping the two. This facilitates the recycling of materials and avoids waste of resources. In addition, a guide hole 32 is provided on the lower arc pressure plate 30, which facilitates the discharge of moisture and prevents the accumulation of moisture inside the drying box 21.

[0055] refer to Figure 2 and Figure 4The coating mechanism 10 includes a liquid collecting box 33 placed on a workbench and having a slot, a material guide box 34 is installed on the top of the liquid collecting box 33 through a column, a multi-way tube is fixedly installed on the bottom of the material guide box 34, a first inclined tube 35 and a second inclined tube 36 at both ends of the multi-way tube are connected to a sleeve 37, and a coating cavity connected to the cable is provided in the sleeve 37; wherein the first inclined tube 35 and the second inclined tube 36 are arranged opposite to each other in sequence along the cable conveying direction, and the pipe diameter of the first inclined tube 35 is larger than the pipe diameter of the second inclined tube 36 by 5-10 cm.

[0056] The liquid collecting box 33 and the material guiding box 34 are connected by a delivery pump 38 fixed on the tube body. The insulating material can enter the multi-way tube through the material guiding box 34, and then enter the coating cavity in the sleeve 37 through the first inclined tube 35 and the second inclined tube 36 respectively. The first inclined tube 35 and the second inclined tube 36 are arranged opposite to each other in the direction of extending the cable conveying, so that the cable can be evenly coated by coating with a large flow rate first and then a small flow rate. At the same time, the insulating material is collected by the liquid collecting box 33, and then re-delivered to the material guiding box 34 by the delivery pump 38, which can facilitate the secondary utilization of resources and is beneficial to environmental protection.

[0057] By setting up the coating mechanism 10, the insulating material can be covered on the filling layer 3 by means of liquid flow, and the pipe diameters on the multi-way pipe are set in a "large and small" manner along the cable transmission direction, so that when the flow rate of the insulating material is adjusted during the flow, it can also be ensured that it is evenly coated on the filling layer 3, and the fluid insulating material can be recycled through the delivery pump 38. The coating of the insulating layer 6 can increase the insulation performance of the cable, prevent current leakage on the conductor, and improve the safety of cable use.

[0058] refer to Figure 1 , Figure 3 and Fig. 9 The winding mechanism 11 includes a third motor 39 placed on the workbench, the output shaft of the third motor 39 extends to the driving wheel 40, the driving wheel 40 and the driven wheel 41 are connected through a conveyor belt 42, and the driving wheel 40 and the driven wheel 41 are correspondingly connected to a reciprocating screw 43 and a winding wheel 44, the reciprocating screw 43 is spirally driven with a screw nut fixed on a moving block 45, and the top of the moving block 45 is movably connected with a transverse correction roller 46 through a U-shaped frame.

[0059] Specifically, a side plate is fixedly installed at the extension of one end of the moving block 45, and a first slide groove 48 movably connected to the first slider 47 is provided at both ends of the side plate. The first slider 47 and the second slider 50 in the second slide groove 49 are connected by a swing rod 51, and the second slider 50 and the bottom end of the inner wall of the second slide groove 49 are connected by a compression spring 52, and one end of the first slider 47 is connected to a vertical correction roller 53 placed between the winding wheel 44 and the horizontal correction roller 46; wherein, the first slider 47 and the second slider 50 are installed at both ends of the swing rod 51 in a rotating connection, and a guide cavity connected to the cable is formed between the vertical correction rollers 53.

[0060] When the moving block 45 moves back and forth on the reciprocating screw 43, it can drive the cable to be evenly wound on the winding wheel 44. In addition, a strip groove connected to the workbench is provided at the bottom of the moving block 45, so that the moving block 45 can play a supporting and connecting role during the translation process, and can prevent position deviation during the movement process, thereby ensuring the accuracy of the movement position. At the same time, the mutual cooperation of the transverse correction roller 46 and the vertical correction roller 53 can ensure the consistency of the cable conveying direction in the horizontal plane. In addition, for the conveying of cables of different sizes, it is often necessary to cooperate with conveying rollers of different sizes. The present patent uses a sliding mechanism, which can be set by the rotation of the swing rod 51, and can be pushed by the slider to make the vertical correction roller 53 move outward or inward at the same time, so that the vertical correction rollers 53 at both ends can adjust the size of the conveying area, and the compression spring 52 at the bottom of the second slider 50 can help its transmission mechanism to reset, and can also prevent the vertical correction roller 53 from clamping the cable too much, which is not conducive to the normal conveying of the cable.

[0061] The winding mechanism 11 can use mechanical transmission to make the moving block 45 move back and forth while the winding wheel 44 rotates, so that the moving block 45 drives the cable to be evenly wound on the winding wheel 44. At the same time, the horizontal correction roller 46 and the vertical correction roller 53 can guide the conveyed cable. The connecting part of the vertical correction roller 53 can also realize adaptive clamping and conveying guidance for cables of different sizes, further ensuring the stability of the winding work.

[0062] Reference Fig.10 , a method for preparing a pressure-resistant and high-temperature resistant communication cable, comprising the following steps:

[0063] S1, twisting multiple strands of wire into a cable core 1 through a twisting machine, and covering the cable core 1 with a filling layer 3 through an extruder to form a protective layer 2;

[0064] S2, intermittently laying a filling layer 3 with a reserved hole at the triangular spacer 5 connected to the elastic body 4, and then movably inserting the cable core 1 with the protective layer 2 formed on the outer wall into the reserved hole;

[0066] S4, coating the filling layer 3 dried in step S3 through a coating mechanism 10, so that an insulating layer 6 is formed on the outer surface of the filling layer 3, and the processed cable is rolled up through a rolling mechanism 11.

[0067] The protective layer 2 can be made of polyethylene or nylon material, which has a certain elastic effect and can play a good role in resisting pressure. The filling layer 3 is made of chlorinated polyethylene material, which has strong chemical stability and excellent acid and alkali resistance. At the same time, the insulating layer 6 is made of liquid silicone, which has good high temperature resistance and corrosion resistance. In addition, the elastomer 4 connected by the triangular spacer 5 can increase the compression resistance of the cable and divide the inside of the cable into multiple areas to prevent the damage of one part inside the cable from directly causing the entire component inside the cable to need to be replaced.

[0068] Specifically, a filling layer 3 with reserved holes is intermittently laid at the triangular spacer 5 connected to the elastomer 4. The intermittent laying can ensure the stability of the structural connection while simplifying the materials, and can expand the filling layer 3 and the triangle. At the same time, the cable core 1 can be pushed and inserted into the filling layer 3 by a threading machine, thereby completing the connection work.
