Description

Technical Field

[0001] This invention belongs to the technical field of construction equipment for power transmission and transformation line engineering, and specifically relates to an automatic crimping device for conductor and ground wire splicing pipes. Background Technology

[0002] Automatic wire splice crimping devices are automated equipment used in the power construction industry, primarily for crimping wire splice tubes. Their main function is to mechanically fix and crimp the wire end to the splice tube, forming a single unit. This device has wide applications in power, electrical engineering, and communications, especially in applications requiring mass production and high-precision splicing. Its key features include: Automated operation: reducing manual labor and improving efficiency and accuracy. High-voltage connection: ensuring stable wire-to-splice connection through precise crimping force, preventing electrical faults due to poor contact. High adaptability: adjustable to different wire and splice tube specifications to meet diverse engineering needs. Labor savings: high degree of automation significantly reduces worker workload. Monitorability: typically equipped with a monitoring system that can monitor the crimping process in real time, ensuring quality at every stage.

[0003] In power construction, automatic crimping devices for conductor and ground wire splice pipes are a very common auxiliary equipment. Currently, there are various types of automatic crimping equipment on the market. However, most of the existing crimping equipment has certain problems in actual use. When using existing equipment to crimp splice pipes, as the splice pipes undergo plastic deformation under pressure, protruding burrs will be generated at the junction of the two sets of crimping molds. These burrs generated during the crimping process are usually manually removed by using pliers or files, which is not only time-consuming and labor-intensive, but also greatly affects the overall construction efficiency and progress. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic crimping device for ground wire splicing tubes.

[0005] The technical solution adopted to solve the above technical problems is: an automatic crimping device for ground wire splicing pipe, including a device body, the device body including a fixed base, and mounting brackets provided on both sides of the top of the fixed base, and limit slots and lifting slides respectively provided on the top and bottom of the inner sides of the two mounting brackets; A lower pressing module is slidably installed between the two lifting slides, and a hydraulic drive mechanism for lifting the lower pressing module is installed in the middle of the fixed base; A separable limiting mechanism is slidably installed between the two limiting slots, and an upper pressing module that matches the lower pressing module is fixedly installed at the bottom of the limiting mechanism; The fixed base has a burr shearing drive mechanism that matches the lower pressing module fixedly installed at the top rear end, which is used to drive the lower pressing module to complete the automatic removal of burrs.

[0006] Furthermore, a bottom cover plate is fixedly installed on the bottom of the fixed base, and foot pedals are provided at the bottom of both the front and rear ends of the bottom cover plate.

[0007] Through the above technical solution, the detachable bottom cover plate is easier to assemble and disassemble quickly, making the hydraulic drive mechanism installed inside the fixed base easier to maintain in daily life. At the same time, the bottom cover plate is equipped with two foot pedals. When the equipment is used on uneven ground, the operator can stabilize the equipment by stepping on the foot pedals to ensure normal use of the equipment.

[0008] Furthermore, the lower pressing module includes a lower mold base body, a lower pressing forming groove is provided at the top center of the lower mold base body, a positioning slot is provided at the bottom center of the lower mold base body, a first limiting protrusion is provided on both sides of the outer wall of the lower mold base body, a lower shearing seat is installed on both sides of the lower mold base body, a limiting groove matching the first limiting protrusion is provided on the inner side of the two lower shearing seats, a second limiting protrusion is provided on the outer side of the two lower shearing seats, and a strip-shaped slot is provided at the rear end of the two lower shearing seats.

[0009] Through the above technical solution, the lower crimping module is an important component of the crimping equipment. It mainly works with the upper crimping module to complete the crimping of the connecting tube. During operation, the connecting tube is first inserted between the two wires to be connected, and then the connecting tube is placed in the lower crimping forming groove. At this time, driven by the hydraulic drive mechanism, the lower die base body and the two lower shearing seats can move upward synchronously. In conjunction with the upper crimping module, the connecting tube can be quickly squeezed and plastically deformed, so that the two wires can be stably connected together through the connecting tube. In addition, after the connecting tube is crimped, the hydraulic drive mechanism will be in a pressure holding state. At the same time, under the squeezing of the lower and upper crimping modules, burrs will be generated at the junction of the two modules. At this time, the two lower shearing seats can continue to move upward under the drive of the burr shearing drive mechanism, so that the two lower shearing seats can be used to quickly shear the burr part.

[0010] Furthermore, the second limiting protrusions on the outer sides of the two lower shear seats are respectively slidably limited within the corresponding lifting grooves.

[0011] The above technical solution can limit the lifting and sliding of the lower mold base body and the two lower shear seats.

[0012] Furthermore, the hydraulic drive mechanism includes a lifting hydraulic cylinder installed inside the fixed base. A lifting seat is fixedly installed at the top of the piston rod of the lifting hydraulic cylinder, and a positioning column inserted into a positioning slot is fixedly connected to the center of the top of the lifting seat.

[0013] Through the above technical solution, the hydraulic drive mechanism serves as the main drive unit in the pressing process. When working, the lifting hydraulic cylinder can drive the lifting seat to move upward through the extension of its piston rod, which in turn can simultaneously drive the lower die seat body and the two lower shear seats to move upward. Thus, the pressing operation of the connecting pipe can be completed through huge extrusion force. After the pressing is completed, the piston rod of the lifting hydraulic cylinder will automatically reset. At this time, under the action of gravity, the lower die seat body and the two lower shear seats will also automatically reset downward.

[0014] Furthermore, the limiting mechanism includes a limiting card seat, the bottom center of which has an installation slot, both sides of the outer wall of the limiting card seat have positioning protrusions, and the top center of the limiting card seat has a fixing handle.

[0015] Through the above technical solution, the limiting mechanism serves as both an installation support structure and a limiting structure. During use, the upper pressing module is fixed to the bottom of the limiting mechanism, while the limiting mechanism needs to be slidably installed between two mounting brackets to fix the relative positions of the limiting mechanism and the upper pressing module. During the subsequent pressing process, the upper pressing module maintains its relative position fixed, while the lower pressing module moves upward under the drive of the hydraulic drive mechanism, thereby completing the pressing and shaping of the connecting tube by extrusion. After pressing is completed, the lower pressing module will reset under the drive of the hydraulic drive mechanism. At this point, to facilitate the removal of the crimped wire, the limiting mechanism can be removed from between the two mounting brackets.

[0016] Furthermore, the two positioning protrusions are respectively slidably limited within their corresponding limiting slots.

[0017] The above technical solution ensures that the limit card can be installed accurately and quickly, and also provides positioning and fixing functions to ensure that the limit card remains stable during the equipment pressing process, without shaking or separation.

[0018] Furthermore, the upper pressing module includes an upper mold base body, an upper pressing forming groove is provided at the center of the bottom of the upper mold base body, limit sliders are fixedly connected to both sides of the outer wall of the upper mold base body, upper shear seats are slidably connected to both sides of the upper mold base body, limit grooves matching the limit sliders are provided on the inner sides of the two upper shear seats, limit blocks are fixedly installed on the top of the two upper shear seats, and a mounting base is fixedly connected to the top of the upper mold base body.

[0019] Through the above technical solution, the upper pressing module and the lower pressing module are used in conjunction with each other. The upper pressing forming groove is opened at the center of the bottom of the upper mold base body. During the pressing process, the pressing and shaping of the connecting tube can be completed through the mutual cooperation between the upper mold base body and the lower mold base body. In addition, upper shearing seats are slidably installed on both sides of the upper mold base body. After the pressing is completed, the two lower shearing seats will move upward under the drive of the burr shearing drive mechanism, so as to quickly complete the automatic shearing of burrs, thus eliminating the need for subsequent manual processing.

[0020] Furthermore, the mounting base is fixed in the mounting slot by multiple screws.

[0021] The above technical solution can ensure the firmness and stability of the connection, and also facilitate quick replacement. When crimping different specifications of splice tubes, different specifications of crimping modules can be replaced according to actual needs.

[0022] Furthermore, the burr shearing drive mechanism includes a shearing hydraulic cylinder fixedly installed at the rear end of the top of the fixed base. A lifting seat is fixedly connected to the top of the piston rod of the shearing hydraulic cylinder. Fixed insertion rods are fixedly connected to both sides of the front end of the lifting seat, and the two fixed insertion rods are respectively inserted into the corresponding strip slots.

[0023] Through the above technical solution, the burr shearing drive mechanism is mainly used for the automatic removal of burrs from the splice pipe after crimping. After the crimping is completed, the piston rod of the shearing hydraulic cylinder will drive the lifting seat and the two fixed insert rods to move upward. At this time, the two fixed insert rods can simultaneously drive the two lower shearing seats to move upward, thereby cooperating with the two upper shearing seats to complete the automatic shearing operation of the burrs. After the shearing is completed, the piston rod of the shearing hydraulic cylinder will drive it to automatically reset.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention, through the design of a simple automatic burr shearing structure, can simultaneously complete the rapid shearing of burrs after the splice pipe is crimped, without the need for manual processing, which not only saves time and effort, but also ensures the overall construction efficiency and construction progress; (2) The present invention, through the design of a combined crimping mold, makes the crimping mold easy and quick to replace, thereby adapting to the crimping processing of different splice pipes, and greatly improving the work efficiency; (3) The present invention, through the design of a combined crimping mold, does not affect the normal crimping processing. After the splice pipe is crimped, the modules on both sides of the mold can also quickly complete the automatic shearing of burrs. At the same time, its simple and compact structural design is also convenient for daily maintenance. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figures 1-16 As shown, an automatic crimping device for grounding wire splice tubes in this embodiment includes a device body 1. The device body 1 includes a fixed base 101. Mounting brackets 102 are provided on both sides of the top of the fixed base 101. Limiting slots 103 and lifting slides 104 are respectively provided on the top and bottom of the inner side of the two mounting brackets 102. A bottom cover plate 105 is fixedly installed on the bottom of the fixed base 101. Foot pedals 106 are provided on the bottom of the front and rear ends of the bottom cover plate 105. The detachable bottom cover plate 105 is more convenient for quick assembly and disassembly, making the hydraulic drive mechanism 3 installed inside the fixed base 101 easier for daily maintenance. At the same time, two foot pedals 106 are provided on the bottom cover plate 105. When the equipment is used on uneven ground, the operator can stabilize the equipment by stepping on the foot pedals 106 to ensure normal use of the equipment.

[0029] Regarding the pressure connector module 2, please refer to... Figures 12-14A lower pressing module 2 is slidably installed between two lifting slides 104. The lower pressing module 2 includes a lower mold base body 201. A lower pressing forming groove 202 is opened at the top center of the lower mold base body 201, and a positioning slot 203 is opened at the bottom center of the lower mold base body 201. First limiting protrusions 204 are provided on both sides of the outer wall of the lower mold base body 201. Lower shearing seats 205 are installed on both sides of the lower mold base body 201. The inner side of each of the two lower shearing seats 205 is provided with a limiting groove 206 that matches the first limiting protrusion 204. The outer side of each of the two lower shearing seats 205 is provided with a second limiting protrusion 207. The rear end of each of the two lower shearing seats 205 is provided with a strip slot 208. The lower pressing module 2 is an important component of the pressing equipment. It mainly works with the upper pressing module 5 to complete the pressing work of the connecting pipe 8. During operation, the lower pressing module 2 can first be used to press the connecting pipe 8. The splice tube 8 is inserted between the two wires 7 to be connected, and then the splice tube 8 is placed in the lower pressing forming groove 202. At this time, driven by the hydraulic drive mechanism 3, the lower mold base body 201 and the two lower shear seats 205 can move upward synchronously. With the cooperation of the upper pressing module 5, the splice tube 8 can be quickly pressed and plastically deformed, so that the two wires 7 can be stably connected together through the splice tube 8. In addition, after the splice tube 8 is pressed, the hydraulic drive mechanism 3 will be in a pressure holding state. At the same time, under the pressure of the lower pressing module 2 and the upper pressing module 5, burrs will be generated at the junction of the two modules. At this time, the two lower shear seats 205 can continue to move upward under the drive of the burr shearing drive mechanism 6, so that the two lower shear seats 205 can be used to quickly shear the burr part.

[0030] In this embodiment, the second limiting protrusions 207 on the outer sides of the two lower shear seats 205 are respectively slidably limited within the corresponding lifting grooves 104, thereby limiting the lifting and sliding of the lower mold base body 201 and the two lower shear seats 205.

[0031] Regarding hydraulic drive mechanism 3, refer to... Figures 1-5A hydraulic drive mechanism 3 for lifting the lower pressing module 2 is installed in the middle of the fixed base 101. The hydraulic drive mechanism 3 includes a lifting hydraulic cylinder 301 installed inside the fixed base 101. A lifting seat 302 is fixedly installed at the top of the piston rod of the lifting hydraulic cylinder 301. A positioning column 303 inserted into the positioning slot 203 is fixedly connected to the center of the top of the lifting seat 302. As the main drive unit in the pressing process, the hydraulic drive mechanism 3 can drive the lifting seat 302 to move upward through the extension of its piston rod when working. This can then drive the lower mold base body 201 and the two lower shear seats 205 to move upward simultaneously. Thus, the pressing operation of the connecting pipe 8 can be completed through huge extrusion force. After the pressing is completed, the piston rod of the lifting hydraulic cylinder 301 will automatically reset. At this time, under the action of gravity, the lower mold base body 201 and the two lower shear seats 205 will also automatically reset downward.

[0032] Regarding limit mechanism 4, please refer to... Figures 1-9 A separable limiting mechanism 4 is slidably installed between two limiting slots 103. The limiting mechanism 4 includes a limiting seat 401, with an installation slot 402 at the bottom center of the limiting seat 401. Positioning protrusions 403 are provided on both sides of the outer wall of the limiting seat 401, and a fixing handle 404 is provided at the top center of the limiting seat 401. The limiting mechanism 4 serves as both an installation support structure and a limiting structure. In use, the upper pressing module 5 is fixed to the bottom of the limiting mechanism 4, while the limiting mechanism 4 needs to be slidably installed on the two mounting brackets. Between the two mounting brackets 102, the relative positions of the limiting mechanism 4 and the upper pressing module 5 are fixed. During the subsequent pressing process, the upper pressing module 5 remains in a fixed relative position, while the lower pressing module 2 moves upward under the drive of the hydraulic drive mechanism 3. This allows the pressing and shaping of the connecting tube 8 to be completed by compression. After pressing, the lower pressing module 2 is reset under the drive of the hydraulic drive mechanism 3. At this time, to facilitate the removal of the wire 7 after pressing, the limiting mechanism 4 can be removed from between the two mounting brackets 102.

[0033] In this embodiment, the two positioning protrusions 403 are respectively slidably limited within the corresponding limiting slots 103. On the one hand, this ensures that the limiting slot 401 can be installed accurately and quickly. On the other hand, it also plays a role in positioning and fixing the limiting slot 401, so as to ensure that the limiting slot 401 can remain stable as a whole during the equipment pressing process and will not shake or separate.

[0034] Regarding the upper crimp module 5, please refer to... Figures 1-11The bottom of the limiting mechanism 4 is fixedly installed with an upper pressing module 5 that matches the lower pressing module 2; the upper pressing module 5 includes an upper mold base body 501, an upper pressing forming groove 502 is opened at the center of the bottom of the upper mold base body 501, limiting sliders 503 are fixedly connected to both sides of the outer wall of the upper mold base body 501, upper shear seats 504 are slidably connected to both sides of the upper mold base body 501, limiting grooves 505 that match the limiting sliders 503 are opened on the inner side of the two upper shear seats 504, and limiting blocks 506 are fixedly installed on the top of the two upper shear seats 504, and the top of the upper mold base body 501 is fixed. The upper pressing module 5 and the lower pressing module 2 are connected to the mounting base 507 and are used in cooperation with each other. The upper pressing forming groove 502 is opened at the center of the bottom of the upper mold base body 501. During the pressing process, the pressing and shaping of the connecting tube 8 can be completed through the cooperation between the upper mold base body 501 and the lower mold base body 201. In addition, upper shearing seats 504 are slidably installed on both sides of the upper mold base body 501. After the pressing is completed, the two lower shearing seats 205 will move upward under the drive of the burr shearing drive mechanism 6, so as to quickly complete the automatic shearing of burrs, thus eliminating the need for manual processing afterward.

[0035] In this embodiment, the mounting base 507 is fixed in the mounting slot 402 by multiple screws, which can not only ensure the firmness and stability of the connection, but also facilitate quick replacement. When crimping different specifications of splice tubes 8, different specifications of crimping modules can be replaced according to actual needs.

[0036] Furthermore, in this embodiment, by adopting a split structure design for both the upper pressing module 5 and the lower pressing module 2, the overall pressing and forming quality is not affected, and the shearing seats on both sides can be moved, thereby facilitating the deburring operation and significantly improving work efficiency.

[0037] Regarding the burr shearing drive mechanism 6, refer to... Figures 12-15A burr shearing drive mechanism 6, matching the lower pressing module 2, is fixedly installed at the top rear end of the fixed base 101. This mechanism drives the lower pressing module 2 to automatically remove burrs. The burr shearing drive mechanism 6 includes a shearing hydraulic cylinder 601 fixedly installed at the top rear end of the fixed base 101. A lifting seat 602 is fixedly connected to the top of the piston rod of the shearing hydraulic cylinder 601. Fixed insertion rods 603 are fixedly connected to both sides of the front end of the lifting seat 602, and the two fixed insertion rods 603 are respectively inserted into the corresponding strip slots 208. The burr shearing drive mechanism 6 is mainly used for the automatic removal of burrs from the connecting tube 8 after pressing. After pressing, the piston rod of the shearing hydraulic cylinder 601 will drive the lifting seat 602 and the two fixed insertion rods 603 to move upward. At this time, the two fixed insertion rods 603 can simultaneously drive the two lower shearing seats 205 to move upward, thereby cooperating with the two upper shearing seats 504 to complete the automatic shearing operation of the burrs. After shearing, the piston rod of the shearing hydraulic cylinder 601 drives it to automatically reset.

[0038] The working principle of this embodiment is as follows: First, the splicing tube 8 is inserted between the two wires 7 to be connected. Then, the splicing tube 8 is placed in the lower pressing forming groove 202. Then, the limiting mechanism 4 and the upper pressing module 5 are slidably installed between the two limiting slots 103. Once preparations are complete, the hydraulic drive mechanism 3 is activated. Driven by the lifting hydraulic cylinder 301, the lower mold base body 201 and the two lower shearing seats 205 can move upward synchronously. In conjunction with the upper pressing module 5, the extrusion of the connecting tube 8 can be completed quickly, causing it to undergo plastic deformation, so that the two wires 7 can be stably connected together through the connecting tube 8. During the crimping process, due to the plastic deformation of the splice tube 8 under pressure, burrs will be generated on both sides of the junction of the lower crimping module 2 and the upper crimping module 5. At this time, the lifting hydraulic cylinder 301 is in a pressure-holding state, and the shearing hydraulic cylinder 601 is started. The piston rod of the shearing hydraulic cylinder 601 will drive the lifting seat 602 and the two fixed insert rods 603 to move upward. At this time, the two fixed insert rods 603 can simultaneously drive the two lower shearing seats 205 to move upward, thereby cooperating with the two upper shearing seats 504 to complete the automatic shearing operation of the burrs. After the shearing is completed, the piston rod of the shearing hydraulic cylinder 601 drives it to automatically reset. At this time, the limit mechanism 4 and the upper crimping module 5 can be removed, and the crimped wire 7 can be removed from the device.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
