[0001] The present invention relates to the technical field of cold-shrinkable tube conveying and processing, and specifically to a high-voltage cold-shrinkable tube conveying and shaping device. Background Art

[0002] As a key component in cable accessories, cold-shrinkable tubes are widely used in the field of power transmission. High-voltage cold-shrinkable tubes are usually injection-molded and vulcanized from elastomeric materials in the factory, and then lined with plastic spiral supports after being expanded in diameter. The high-voltage cold-shrinkable tube conveying and shaping device is a professional device for conveying and shaping high-voltage cold-shrinkable tubes. In the actual production process, high-voltage cold-shrinkable tubes need to be conveyed and shaped to meet the installation and use requirements. The high-voltage cold-shrinkable tube conveying and shaping device is a professional device for conveying and shaping high-voltage cold-shrinkable tubes.

[0004] The existing conveying and shaping devices use belts to convey cold-shrinkable tubes to the processing position for shaping and expanding. For the shaping of cold-shrinkable tubes, the existing technical means are often relatively simple. The device only fixes the cold-shrinkable tubes to be shaped by simple die extrusion, resulting in insufficient stability of the cold-shrinkable tubes during the shaping and expanding process, easy occurrence of cold-shrinkable tube offset problems, uneven quality of the shaped cold-shrinkable tubes, and a high rejection rate. At the same time, the existing shaping devices are difficult to adapt to the diverse shaping requirements of cold-shrinkable tubes of different specifications. In view of the above problems, a high-voltage cold-shrinkable tube conveying and shaping device is proposed. Summary of the Invention

The bottom of the base is welded to the top of the conveying mechanism, and the top of the base is welded to the bottom of the lower die. Two movable rods are symmetrically and slidably installed on both sides of the lower die. One end of the movable rod close to the inner side of the lower die is fixedly connected to an elastic clamping plate.

[0007] Preferably, extension plates are symmetrically fixedly connected to both sides of the upper die. One end of the movable rod away from the elastic clamping plate passes through the lower die, and two bendable plates that can be symmetrically bent are symmetrically rotatably connected.

[0008] Preferably, connecting plates are symmetrically welded to both sides of the lower die. One end of the two bendable plates away from the movable rod is rotatably connected to the inner side of the connecting plate, and the top end of the bendable plate at the top is slidably connected to the bottom of the extension plate.

[0009] Preferably, the top of the lower die is inserted into the bottom of the upper die. An electric push rod two is fixedly installed on the top of the cross plate, and a push plate is arranged at one end of the top of the cross plate close to the fixing component. The output end of the electric push rod two is fixedly connected to one end of the push plate.

[0010] Preferably, the conveying mechanism includes a processing table, a conveyor belt, and a driving motor. The conveyor belt and the driving motor are both installed on the top of the processing table. A blanking hole is penetrated and opened at one end of the processing table close to the expansion die.

[0011] Preferably, baffles are symmetrically arranged on both sides of the conveyor belt. Electric push rods one are symmetrically fixedly installed on the top of the processing table. The bottom of the baffle is fixedly installed on the top of the processing table.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

At the same time, the rubber elastic pad can press the cold-shrinkable tube tightly under the elastic force of the plurality of springs. Through the combination of the elastic pressing plate, the rubber elastic pad and the plurality of springs, longitudinal limitation of the cold-shrinkable tube is carried out. At the same time, when the upper mold moves downward, the extension plate presses the bending plate, and the bending plate pushes the movable rod and the elastic clamping plate towards the cold-shrinkable tube, so that the two elastic clamping plates clamp the cold-shrinkable tube. The two elastic clamping plates clamp the cold-shrinkable tube front and back. The fixing mechanism effectively fixes the high-voltage cold-shrinkable tube by longitudinally limiting and clamping the cold-shrinkable tube front and back, avoiding the offset of the cold-shrinkable tube during the shaping and expansion process, ensuring the shaping and expansion accuracy, reducing the waste rate. At the same time, the adjustability of the fixing mechanism enables it to adapt to high-voltage cold-shrinkable tubes of different specifications, improving the utilization rate of the equipment; 2. In the present invention, the limiting plate is driven to move by the first electric push rod, so that the distance between the two limiting plates is the same as the outer diameter of the cold-shrinkable tube. The cross plate is driven to move downward by the first cylinder, so that the distance between the cross plate and the conveyor belt is the same as the outer diameter of the cold-shrinkable tube. By adjusting the positions of the limiting plate and the cross plate, the cold-shrinkable tube during the conveying process is limited according to the specifications of the high-voltage cold-shrinkable tube to be processed, ensuring that the cold-shrinkable tube can move stably with the conveyor belt; at the same time, when the cold-shrinkable tube is completed with shaping and expansion, the second electric push rod drives the push plate to move, so that the shaped and expanded cold-shrinkable tube is output downward from the blanking hole, completing the automatic blanking of the cold-shrinkable tube. The conveying and shaping equipment reduces manual intervention and adjustment time through automated operation and precise control. The equipment can quickly and stably complete the conveying and shaping and expansion of high-voltage cold-shrinkable tubes, improving production efficiency and meeting the needs of large-scale production of enterprises.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1: Refer to Figures 1-7As shown in the figure: A high-pressure cold-shrinkable tube conveying and shaping device, including a conveying mechanism 1, a driving device 3 and an expansion die 4. The driving device 3 is fixedly installed at one end of the conveying mechanism 1, and the output end of the driving device 3 is fixedly connected to one end of the expansion die 4. A fixing mechanism 2 is installed at the end of the conveying mechanism 1 close to the expansion die 4. The fixing mechanism 2 includes a support plate 21, a first cylinder 22, a second cylinder 23, a fixing component 24 and a cross plate 25. The first cylinder 22 and the second cylinder 23 are respectively fixedly installed at both ends of the top of the support plate 21. The bottom output end of the first cylinder 22 is fixedly connected to the top of the cross plate 25. The fixing component 24 is arranged at the bottom of the support plate 21 at one end of the second cylinder 23. The fixing component 24 includes a base 241, a lower die 242, an upper die 243 and a top plate 244. The bottom output end of the second cylinder 23 is fixedly connected to the top of the upper die 243. The top plate 244 is fixedly installed on the top wall of the upper die 243, and an elastic pressing plate 245 is fixedly connected to the middle position of the bottom of the top plate 244. Grooves 246 are symmetrically opened at both ends of the bottom of the top plate 244. A plurality of springs 247 are fixed inside the grooves 246, and the bottom of the springs 247 is fixedly connected to a rubber elastic pad 248. The bottom of the base 241 is welded to the top of the conveying mechanism 1, and the top of the base 241 is welded to the bottom of the lower die 242. Two movable rods 249 are symmetrically and slidably installed on both sides of the lower die 242. One end of the movable rod 249 close to the inner side of the lower die 242 is fixedly connected to an elastic clamping plate 250. Extension plates 253 are symmetrically and fixedly connected to both sides of the upper die 243. One end of the movable rod 249 away from the elastic clamping plate 250 passes through the lower die 242, and two bendable bending plates 251 that can be symmetrically bent are symmetrically and rotatably connected. Connecting plates 252 are symmetrically welded to both sides of the lower die 242. One end of the two bending plates 251 away from the movable rod 249 is rotatably connected to the inner side of the connecting plate 252. The top end of the bending plate 251 at the top is slidably connected to the bottom of the extension plate 253. The top of the lower die 242 is inserted into the bottom of the upper die 243.

[0019] In this embodiment, when the cold-shrinkable tube moves into the lower die 242, the second cylinder 23 drives the upper die 243 and the top plate 244 to move downward until the bottom of the upper die 243 is inserted into the top of the lower die 242. At this time, the elastic pressing plate 245 at the bottom of the top plate 244 presses on the top of the cold-shrinkable tube. The position where the bottom of the elastic pressing plate 245 is in contact with the cold-shrinkable tube is made of an elastic rubber material. At the same time, the rubber elastic pads 248 at both ends of the bottom of the top plate 244 press on the top wall of the cold-shrinkable tube, and the rubber elastic pads 248 can press the cold-shrinkable tube tightly under the elastic force of the plurality of springs 247. Through the combination of the elastic pressing plate 245, the rubber elastic pads 248 and the plurality of springs 247, the cold-shrinkable tube can be automatically pressed tightly during the downward movement of the upper die 243, thereby longitudinally limiting the cold-shrinkable tube. Meanwhile, during the downward movement of the upper die 243, the upper die 243 drives the extension plates 253 on both sides to move downward. Since the bottom of the extension plate 253 is slidably connected to the bending plate 251 near the top (as Figure 7 shown, the bending plate 251 is a plate structure that can be symmetrically bent in the middle. One end of the two bending plates 251 is rotatably installed on one side of the connecting plate 252, and the other end of the two bending plates 251 is rotatably installed on one end of the movable rod 249). When the extension plate 253 moves downward, the extension plate 253 presses the bending plate 251 near the top, so that the two bending plates 251 are unfolded. The bending plate 251 pushes the movable rod 249 and the elastic clamping plate 250 towards the cold shrinkable tube, so that the two elastic clamping plates 250 clamp the cold shrinkable tube, and the cold shrinkable tube is clamped front and back by the two elastic clamping plates 250; The fixing mechanism 2 is combined by the elastic pressing plate 245, the rubber elastic pad 248 and a plurality of springs 247. During the downward movement of the upper die 243, the cold shrinkable tube can be automatically pressed, so as to longitudinally limit the cold shrinkable tube. The cold shrinkable tube can be clamped front and back by the two elastic clamping plates 250. Through the fixing mechanism 2, the high-pressure cold shrinkable tube can be clamped and fixed in all directions and with high precision. The effective fixing of the high-pressure cold shrinkable tube avoids the offset of the cold shrinkable tube during the shaping and expansion process, effectively solves the problems of poor stability and easy offset of the high-pressure cold shrinkable tube in the shaping and expansion process in traditional equipment, ensures the shaping and expansion accuracy, makes the size of the produced high-pressure cold shrinkable tube meet the requirements, and the surface is not damaged, improves the product quality, reduces the scrap rate, reduces the damage and scrap caused by the offset of the cold shrinkable tube, reduces the raw material loss. At the same time, the adjustable nature of the fixing mechanism 2 enables it to adapt to high-pressure cold shrinkable tubes of different specifications, improving the utilization rate of the equipment.

[0020] Embodiment Two: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 8As shown in the figure, an electric push rod two 27 is fixedly installed at the top of the horizontal plate 25, and a push plate 26 is arranged at one end of the top of the horizontal plate 25 close to the fixing component 24. The output end of the electric push rod two 27 is fixedly connected to one end of the push plate 26. The conveying mechanism 1 includes a processing table 11, a conveyor belt 12 and a driving motor 13. The conveyor belt 12 and the driving motor 13 are both installed at the top of the processing table 11. A blanking hole 15 is penetrated and opened at one end of the processing table 11 close to the expansion mold 4. Baffles 14 are symmetrically arranged on both sides of the conveyor belt 12. Electric push rods one 16 are symmetrically and fixedly installed at the top of the processing table 11. The bottom of the baffle 14 is fixedly installed with the top of the processing table 11. Limiting plates 19 are symmetrically arranged on both sides of the top of the conveyor belt 12. The output end of the electric push rod one 16 is fixedly connected to a fixing plate 17. A plurality of sliding rods 18 are slidably connected to one side of the baffle 14. One end of the plurality of sliding rods 18 is fixedly installed with one side of the fixing plate 17, and the other end of the plurality of sliding rods 18 is fixedly connected to one side of the limiting plate 19. Both ends of the bottom of the support plate 21 are fixedly installed with the top of the baffle 14.

[0021] In this embodiment, after the cold shrinkable tube is clamped and fixed, the driving device 3 drives the expansion mold 4 to move, so that the expansion mold 4 expands the cold shrinkable tube. After the expansion is completed, the driving device 3 drives the expansion mold 4 to move out from one end of the cold shrinkable tube. At this time, the cylinder two 23 drives the upper mold 243, the top plate 244 and the extension plate 253 to move upward to return to the original position. At this time, the movable rod 249 drives the elastic clamping plate 250 to move away from the cold shrinkable tube. The electric push rod two 27 drives the push plate 26 to move towards the cold shrinkable tube, as Figure 8 shown. The push plate 26 can push the cold shrinkable tube towards the expansion mold 4, so that the cold shrinkable tube after shaping and expansion is output downward through the blanking hole 15, completing the entire conveying and shaping process. Just wait for the next cold shrinkable tube to be conveyed and shaped and expanded. Through automated operation and precise control, this conveying and shaping equipment reduces manual intervention and adjustment time. The equipment can quickly and stably complete the conveying and shaping and expansion work of high-voltage cold shrinkable tubes, getting rid of the problem that the existing conveying and shaping equipment are independent of each other and need manual connection, greatly improving the production efficiency and meeting the needs of large-scale production of enterprises. When using this device to convey and shape the cold-shrinkable tube, first preset the operating parameters of the driving motor 13, the first cylinder 22, the second cylinder 23, the second electric push rod 27 and the driving device 3 through the controller, so that the conveying mechanism 1, the fixing mechanism 2 and the driving device 3 cooperate with each other to better convey and shape the cold-shrinkable tube. According to the specifications of the high-voltage cold-shrinkable tube to be processed, turn on the first electric push rod 16 through the controller. The first electric push rod 16 drives the fixing plate 17 to move towards the baffle 14. Since one end of multiple sliding rods 18 is fixedly installed on one side of the fixing plate 17 and the other end of multiple sliding rods 18 is fixedly connected to one side of the limiting plate 19, the two limiting plates 19 are driven to approach the middle position of the conveyor belt 12, so that the distance between the two limiting plates 19 is the same as the outer diameter of the cold-shrinkable tube. At the same time, turn on the first cylinder 22 through the controller. The first cylinder 22 drives the cross plate 25 to move downward until the distance between the cross plate 25 and the conveyor belt 12 is the same as the outer diameter of the cold-shrinkable tube. At this time, place the cold-shrinkable tube to be processed at the starting end of the top of the conveyor belt 12, start the equipment, and the driving motor 13 drives the conveyor belt 12 to run, so that the cold-shrinkable tube moves along with the conveyor belt 12 towards the fixing mechanism 2 (there are several anti-slip rubber pads on the outer wall of the conveyor belt 12, and the anti-slip rubber pads can increase the friction between the conveyor belt 12 and the cold-shrinkable tube to ensure that the cold-shrinkable tube can move stably along with the conveyor belt 12).

[0022] The usage method and working principle of this device: When using this device to convey and shape the cold-shrinkable tube, turn on the first electric push rod 16 through the controller. The first electric push rod 16 drives the fixing plate 17 to move towards the baffle 14. Since one end of multiple sliding rods 18 is fixedly installed on one side of the fixing plate 17 and the other end of multiple sliding rods 18 is fixedly connected to one side of the limiting plate 19, the two limiting plates 19 are driven to approach the middle position of the conveyor belt 12, so that the distance between the two limiting plates 19 is the same as the outer diameter of the cold-shrinkable tube. At the same time, turn on the first cylinder 22 through the controller. The first cylinder 22 drives the cross plate 25 to move downward until the distance between the cross plate 25 and the conveyor belt 12 is the same as the outer diameter of the cold-shrinkable tube. At this time, place the cold-shrinkable tube to be processed at the starting end of the top of the conveyor belt 12, start the equipment, and the driving motor 13 drives the conveyor belt 12 to run, so that the cold-shrinkable tube moves along with the conveyor belt 12 towards the fixing mechanism 2. The two side limiting plates 19 and the top cross plate 25 can play a good limiting role on the cold-shrinkable tube. The two side limiting plates 19 prevent the cold-shrinkable tube from shifting left and right during the conveying process. At the same time, the cross plate 25 can perform further limiting when the cold-shrinkable tube is about to move to the fixing mechanism 2, so that the cold-shrinkable tube can move stably into the lower mold 242 under the action of inertia; When the cold shrinkable tube moves into the lower die 242, the second cylinder 23 drives the upper die 243 and the top plate 244 to move downward until the bottom of the upper die 243 is inserted into the top of the lower die 242. At this time, the elastic pressing plate 245 at the bottom of the top plate 244 presses on the top of the cold shrinkable tube. The position where the bottom of the elastic pressing plate 245 fits with the cold shrinkable tube is made of elastic rubber material. At the same time, the rubber elastic pads 248 at both ends of the bottom of the top plate 244 press on the top wall of the cold shrinkable tube, and the rubber elastic pads 248 can press the cold shrinkable tube tightly under the elastic force of multiple springs 247. Through the combination of the elastic pressing plate 245, the rubber elastic pads 248 and multiple springs 247, the cold shrinkable tube can be automatically pressed tightly during the downward movement of the upper die 243, so as to longitudinally limit the cold shrinkable tube; At the same time, during the downward movement of the upper die 243, the upper die 243 drives the extension plates 253 on both sides to move downward. Since the bottom of the extension plate 253 is slidably connected to the bending plate 251 near the top, when the extension plate 253 moves downward, the extension plate 253 presses the bending plate 251 near the top, so that the two bending plates 251 are unfolded, and the bending plates 251 push the movable rod 249 and the elastic clamping plate 250 towards the cold shrinkable tube, so that the two elastic clamping plates 250 clamp the cold shrinkable tube, and the cold shrinkable tube is clamped front and back through the two elastic clamping plates 250; The fixing mechanism 2 can automatically press the cold shrinkable tube tightly during the downward movement of the upper die 243 through the combination of the elastic pressing plate 245, the rubber elastic pads 248 and multiple springs 247, so as to longitudinally limit the cold shrinkable tube. The cold shrinkable tube can be clamped front and back through the two elastic clamping plates 250. Through the effective fixing of the high-pressure cold shrinkable tube by the fixing mechanism 2, the offset of the cold shrinkable tube during the shaping and expansion process is avoided, the shaping and expansion accuracy is guaranteed, the size of the produced high-pressure cold shrinkable tube meets the requirements, and the surface is not damaged, improving the product quality, reducing the rejection rate, reducing the breakage and waste caused by the offset of the cold shrinkable tube, reducing the raw material loss. At the same time, the adjustability of the fixing mechanism 2 enables it to adapt to high-pressure cold shrinkable tubes of different specifications, improving the utilization rate of the equipment; After the cold shrinkable tube is clamped and fixed, the driving device 3 drives the expansion die 4 to move, so that the expansion die 4 expands the cold shrinkable tube. After the expansion is completed, the driving device 3 drives the expansion die 4 to move out from one end of the cold shrinkable tube. At this time, the second cylinder 23 drives the upper die 243, the top plate 244 and the extension plate 253 to move upward to the original position. At this time, the movable rod 249 drives the elastic clamping plate 250 away from the cold shrinkable tube, and the second electric push rod 27 drives the push plate 26 to move towards the cold shrinkable tube, as Figure 8 shown, the push plate 26 can push the cold shrinkable tube towards the expansion die 4, so that the shaped and expanded cold shrinkable tube is output downward from the blanking hole 15, completing the entire conveying and shaping process, and waiting for the next cold shrinkable tube to be conveyed and shaped and expanded.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
