Description

Technical Field

[0001] This utility model belongs to the field of power engineering cable crimping technology, and in particular relates to a power engineering cable crimping device. Background Technology

[0002] In electrical engineering, cable crimping is a core process that uses mechanical force to permanently connect conductors to terminals. Essentially, it achieves molecular-level bonding through metal deformation, ensuring reliable current transmission and mechanical strength. Compared to traditional hinged or welded connections, crimping offers three advantages: First, the cold-pressing technology avoids damage to insulation materials from high temperatures, making it particularly suitable for common cable sheaths such as PE and PVC. Second, the contact resistance after crimping is significantly reduced, and it is less prone to oxide layer formation during long-term operation, making it especially suitable for high-load scenarios. Third, crimped joints can withstand greater mechanical stress and remain stable under vibration or temperature variations. This reliability makes it the preferred solution for conductor connections in critical equipment such as substations and distribution boxes.

[0003] Comparing with Chinese Patent CN221947578U, a cable crimping device for power transmission line construction is disclosed, including a processing table. A movable platform is provided on the top of the processing table, and two mounting seats are fixedly connected to the top of the movable platform. Cable crimping plates are detachably installed on the top of the mounting seats. Multiple cable crimping grooves are opened on the top of the cable crimping plates. A groove is provided on the top of the processing table, and a cyclic moving mechanism for cyclically adjusting the position of the movable platform is installed in the groove of the processing table. The cyclic moving mechanism drives the movable platform to move back and forth on the processing table, thereby cyclically moving the two cable crimping plates to the under of the crimping mechanism for cable crimping operations. While the cable on one cable crimping plate is being crimped, the cable crimped on the other cable crimping plate can be removed and reloaded. Through the design of cyclically switching between the two cable crimping plates, downtime is greatly reduced and processing efficiency is improved.

[0004] However, the aforementioned patent uses reciprocating feeding combined with single vertical stamping, which results in an intermittent time for pressing a single piece. This reduces the speed of feeding and pressing, and is prone to over-pressing or incomplete pressing. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a power engineering cable crimping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A power engineering cable crimping device includes several mold assemblies for crimping cables vertically and vertically, and a frame assembly for supporting continuous movement. A feeding assembly for continuous cyclic movement and pushing is located in the middle of the frame assembly, and an extrusion assembly for pressing down and rotating to apply force is located above the feeding assembly. The frame assembly includes a base plate with two symmetrically arranged support frames at its front and rear. A support platform is located inside the support frame, and a limiting edge is located outside the support platform. The feeding assembly includes two symmetrically arranged conveyor rollers with a conveyor belt installed between them. A second motor is located at one end of one of the conveyor rollers, and several flexible pushing mechanisms for propelling the mold assembly forward are evenly distributed on the conveyor belt. The extrusion assembly includes a fixed frame with an adjustment mechanism at its top for vertical movement to adjust its height. A spinning roller is located at the bottom of the adjustment mechanism, and a first motor is located at one end of the spinning roller.

[0008] Furthermore, the pushing mechanism includes a fixed base on which a flexible upright plate is mounted.

[0009] Furthermore, the flexible vertical panel is rectangular and made of silicone material.

[0010] Furthermore, the adjustment mechanism includes a hydraulic cylinder fixedly installed at the top of the fixed frame, a lifting frame is installed at the bottom telescopic end of the hydraulic cylinder, and a limit slide rod is provided on the lifting frame.

[0011] Furthermore, two limiting slide rods are symmetrically arranged, respectively on both sides of the hydraulic cylinder, and are slidably connected to the fixed frame.

[0012] Furthermore: the mold assembly includes an upper module and a lower module, a molding cavity is provided between the upper module and the lower module, a clearance groove is provided on the bottom surface of the lower module, a guide post is provided on the bottom surface of the upper module, and a guide sleeve is provided on the lower module.

[0013] Furthermore, two guide posts and two guide sleeves are provided, arranged diagonally and corresponding one-to-one.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] By setting up a feeding assembly with a flexible vertical plate, multiple mold assemblies can be continuously and automatically pushed to the extrusion station in sequence, replacing the cumbersome steps of manual feeding, positioning, and unloading in the traditional method. The spinning roller in the extrusion assembly rolls the mold assembly while driving it to move, realizing a continuous pressing process of "moving and pressing at the same time", eliminating the intermittent time in single-piece pressing and making a qualitative leap in production efficiency. The force is applied by rotating rolling (spinning), which is gentler and more uniform than traditional vertical stamping. It can fully deform and fuse the metal lattice of the cable, effectively preventing over-pressure or incomplete pressing, and improving the mechanical strength and conductivity of the pressing point. The pushing mechanism uses a flexible vertical plate (such as silicone material), which is elastic. When the die assembly is obstructed or slows down under the pressure, the flexible vertical plate can bend elastically and slide out of the bottom of the module, thus avoiding problems such as equipment jamming, component damage, or conveyor belt slippage that may be caused by rigid pushing. The adjustment mechanism (such as a hydraulic cylinder) can precisely control the pressing height of the spinning roller to adapt to different specifications of cables and dies, enhancing the versatility and process adaptability of the device. It successfully solves the technical problems of low efficiency, poor quality consistency, and low degree of automation in traditional cable crimping technology. It is particularly suitable for scenarios in power engineering that require large-scale, high-quality cable crimping, and has outstanding technical advantages and broad industrial application prospects.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 A power engineering cable crimping device includes several mold assemblies 1 for crimping cables from top to bottom, and a frame assembly 2 for supporting continuous movement. A feeding assembly 3 for continuous pushing and circulating movement is provided in the middle of the frame assembly 2, and an extrusion assembly 4 for pressing down and rotating to apply force is provided above the feeding assembly 3.

[0026] In this embodiment: the frame assembly 2 includes a base plate 201, and two support frames 202 are symmetrically arranged at the front and rear of the base plate 201. A support platform 203 is provided on the inner side of the support frame 202, and a limiting edge 204 is provided on the outer side of the support platform 203. The support frame 202 fixed on the base plate 201 supports the mold assembly 1 to move forward through the support platform 203, and the limiting edge 204 prevents the lower module 102 from falling out.

[0027] In this embodiment: the feeding component 3 includes two symmetrically arranged conveyor rollers 401, and a conveyor belt 405 is installed between the conveyor rollers 401. One end of one of the conveyor rollers 401 is provided with a second motor 402. Several flexible pushing mechanisms for pushing the mold assembly 1 forward are evenly distributed on the conveyor belt 405. The pushing mechanism includes a fixed base 403, and a flexible upright plate 404 is installed on the fixed base 403. The flexible upright plate 404 is rectangular and made of silicone material. The second motor 402 drives the conveyor rollers 401 to rotate, pushing the conveyor belt 405 forward through the fixed base 403 and driving the flexible upright plate 404 forward. The flexible upright plate 404 inserts into the clearance groove 106 to push the lower module 102 forward along the support platform 203. At the same time, while the mold assembly 1 is squeezed and moves forward slowly, the flexible upright plate 404 bends under the action of elasticity and slides out of the bottom of the lower module 102, ensuring that the conveyor belt 405 moves forward stably and evenly, and continuously pushes the subsequent mold assembly 1.

[0028] In this embodiment: the extrusion assembly 4 includes a fixed frame 301, the top of the fixed frame 301 is provided with an adjustment mechanism for moving up and down to adjust the height, the bottom of the adjustment mechanism is provided with a spinning roller 304, and one end of the spinning roller 304 is provided with a first motor 305; the adjustment mechanism includes a hydraulic cylinder 302 fixedly installed at the top of the fixed frame 301, the bottom telescopic end of the hydraulic cylinder 302 is provided with a lifting frame 303, and the lifting frame 303 is provided with a limit slide rod 306; two limit slide rods 306 are symmetrically arranged, respectively set on both sides of the hydraulic cylinder 302. On the side, it is slidably connected to the fixed frame 301; the fixed frame 301 supports the hydraulic cylinder 302 to push the lifting frame 303 to drive the spinning roller 304 to move down to the set position, so that the spinning roller 304 presses down on the upper module 101, ensuring that the upper module 101 and the lower module 102 complete the mold closing and the cable forming is pressed. The limiting slide rod 306 limits the up and down movement direction of the lifting frame 303, and the lifting frame 303 supports the first motor 305 to drive the spinning roller 304 to rotate, so that the mold assembly 1 is continuously squeezed while moving, ensuring the continuity of cable pressing;

[0029] In this embodiment: the mold assembly 1 includes an upper module 101 and a lower module 102. A molding cavity 103 is provided between the upper module 101 and the lower module 102. A relief groove 106 is provided on the bottom surface of the lower module 102. A guide post 104 is provided on the bottom surface of the upper module 101. A guide sleeve 105 is provided on the lower module 102. Two guide posts 104 and two guide sleeves 105 are provided, which are diagonally distributed and correspond one to one. The cable to be crimped is placed into the molding cavity 103 between the lower module 102 and the upper module 101, and the guide post 104 of the upper module 101 is inserted into the guide sleeve 105 of the lower module 102 to align the upper module 101 and the lower module 102. The assembled whole is then placed on the support platform 203 of the support frame 202. The spinning roller 304 presses down on the upper module 101, and the upper module 101 and the lower module 102 complete the mold closing, and the crimped cable is formed.

[0030] Working principle: First, place the cable to be crimped into the forming cavity 103 between the lower module 102 and the upper module 101, and insert the guide post 104 of the upper module 101 into the guide sleeve 105 of the lower module 102 to align the upper module 101 and the lower module 102. Then, place the assembled unit on the support platform 203 of the support frame 202. The support frame 202 fixed on the base plate 201 supports the second motor 402 to drive the conveyor roller 401 to rotate, pushing the conveyor belt 405 to drive the flexible vertical plate 404 forward through the fixed seat 403. The flexible vertical plate 404 inserts into the clearance groove 106 to push the lower module 102 to move forward along the support platform 203. The limiting edge 204 prevents the lower module 102 from falling out. At the same time, the fixed frame... Hydraulic cylinder 302 supports the lifting frame 303, which in turn moves the spinning roller 304 to a set position. The spinning roller 304 presses down on the upper module 101, ensuring that the upper module 101 and the lower module 102 complete the mold closing and the cable forming. The limiting slide rod 306 limits the up and down movement direction of the lifting frame 303. The lifting frame 303 supports the first motor 305 to drive the spinning roller 304 to rotate, so that the mold assembly 1 is continuously squeezed while moving, ensuring the continuity of cable crimping. At the same time, while the mold assembly 1 is slowly advancing under the pressure, the flexible vertical plate 404 bends under the elastic action and slides out of the bottom of the lower module 102, ensuring that the conveyor belt 405 advances stably and evenly, continuously pushing the subsequent mold assembly 1.
