Description

Technical Field

[0001] This utility model belongs to the field of copper-clad steel grounding rod processing technology, specifically relating to a copper-clad steel grounding rod shearing device. Background Technology

[0002] Copper-clad steel grounding rods are a common type of grounding device used to protect electronic equipment and ensure personal safety. They consist of a steel bar coated with a moderately thick layer of copper, giving the grounding rod both the strength of steel and the conductivity of copper. The high strength of the steel ensures the structural stability and durability of the grounding rod, while the excellent conductivity of copper ensures reliable grounding.

[0003] Copper-clad steel grounding rods are produced by shearing long materials during processing. To improve shearing efficiency, mechanized shearing is generally used. The long material passes through the die hole of the mold and is then sheared by a cutting blade driven by a punching cylinder. For example, CN219066499U proposes a copper-clad steel grounding wire production equipment. The copper-clad steel passes through the circular groove of the wire-passing block, and a hydraulic device drives an alloy cutting blade fixedly connected between two moving blocks to move downwards to cut the copper-clad steel.

[0004] However, in the aforementioned shearing equipment, the copper-clad steel long material needs to continuously pass through the circular groove. Over a long period of use, wear on the circular groove is inevitable. Once the circular groove is worn, the entire main body of the mold needs to be replaced, otherwise the processing accuracy and quality will be affected. At the same time, the lower edge of the circular groove at the front end is easily worn during the stamping and shearing of copper-clad steel. Once the lower edge is worn, the entire main body of the mold also needs to be replaced, which is very inconvenient and will increase the replacement cost. Utility Model Content

[0005] This utility model provides a copper-clad steel grounding rod shearing device. The shearing device is equipped with a mold tube to avoid friction between the copper-clad steel long material and the mold base when it enters and exits the circular groove. The mold tube can be replaced after it is worn, avoiding the need to replace the entire mold base after the circular groove is worn, thus saving costs. After the lower edge of the mold's circular groove opening is worn, the position of the lower edge can be adjusted by rotating the mold tube, allowing for continued use and enhancing durability, further saving costs, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper-clad steel grounding rod shearing device, comprising a base, a mold base mounted on the base, a mold tube extending through the front and rear of the mold base, the front end face of the mold tube being flush with the mold base, a positioning mechanism for positioning the mold tube mounted on the mold base, and the ability to assemble and disassemble the mold tube, and a shearing mechanism mounted on the mold base.

[0007] Preferably, the positioning mechanism includes a mold base cover plate, the bottom surface of which contacts the mold base, and the mold base cover plate and the mold base contact area are provided with upper and lower placement grooves corresponding to the mold tube, the upper and lower placement grooves together forming a positioning groove.

[0008] Preferably, the outer wall of the middle part of the mold tube is provided with a protruding polyhedral part, and the positioning groove is provided with a polyhedral groove corresponding to the polyhedral part.

[0009] Preferably, the bottom surface of the mold base cover plate is provided with multiple connecting parts, the mold base is provided with connecting grooves corresponding to the multiple connecting parts, the connecting parts and the mold base are provided with corresponding screw holes, and the mold base and the connecting parts are fixed together by screws.

[0010] Preferably, the mold base is provided with limiting grooves on both sides, and the mold base cover plate is provided with limiting plates on both sides.

[0011] Preferably, the shearing mechanism includes a shearing cylinder and a cutter. The shearing cylinder is fixed on the frame and faces downward. A connecting plate is fixed to the piston rod end of the shearing cylinder. The cutter is fixed below the connecting plate and is located on the front side of the mold base.

[0012] Preferably, the bottom surface of the connecting plate is provided with a guide post, the mold base is provided with a guide hole corresponding to the guide post, and the guide post is covered with a buffer spring.

[0013] Preferably, the inner walls of the front and rear ports of the mold tube are provided with annular grooves, and elastic rings are fixed in the annular grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Setting up a mold tube can prevent the copper-clad steel long material from rubbing against the mold base when entering and exiting the circular groove. Moreover, the mold tube can be replaced after it is worn, avoiding the need to replace the entire mold base after the circular groove is worn, thus saving costs.

[0016] 2. After the lower edge of the mold's circular groove is worn, the position of the lower edge can be adjusted by rotating the mold tube, and it can continue to be used. When one end edge is worn and cannot be used, the front and rear ends of the mold tube can be swapped to continue using it, thereby enhancing durability and further saving costs.

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a copper-clad steel grounding rod shearing device, including a base 1, a mold base 2 mounted on the base 1, a mold tube 3 extending through the front and rear of the mold base 2, the front end of the mold tube 3 being flush with the mold base 2, a positioning mechanism for positioning the mold tube 3 mounted on the mold base 2, and the ability to assemble and disassemble the mold tube 3, and a shearing mechanism mounted on the mold base 2. During processing, a circular groove is formed inside the mold tube 3, the inner diameter of which is designed to match the outer diameter of the copper-clad steel. The copper-clad steel long material passes through the circular groove of the mold tube 3, and after the front end protrudes by a set length, the shearing mechanism descends to complete the shearing of the copper-clad steel long material, and then rises to reset. The same principle is used to cycle and complete the continuous fixed-length shearing of the copper-clad steel long material. Because the mold tube 3 is set, the friction between the copper-clad steel long material entering and exiting the circular groove and the mold base 2 is avoided, and the mold tube 3 can be replaced after wear, avoiding the need to replace the entire mold base 2 after the circular groove is worn.

[0025] Specifically, the positioning mechanism includes a mold base cover plate 4, the bottom surface of which contacts the mold base 2. The contact area between the mold base cover plate 4 and the mold base 2 is provided with upper and lower placement grooves corresponding to the mold tube 3, and the upper and lower placement grooves together form a positioning groove 5. In this embodiment, the mold tube 3 can be installed and removed by opening the mold base cover plate 4, and the positioning groove 5 is provided to prevent the mold tube 3 from shaking and loosening.

[0026] Specifically, the outer wall of the middle part of the mold tube 3 is provided with a protruding polyhedral part 6, and the positioning groove 5 is provided with a polyhedral groove 7 corresponding to the polyhedral part 6. In this embodiment, the lower edge of the front circular groove is easily worn during the stamping and shearing of copper-clad steel. After the lower edge is worn, the mold tube 3 can be rotated in the positioning groove 5 by opening the mold base cover plate 4. Since the polyhedral part 6 and the polyhedral groove 7 can still be positioned after rotation, the mold base cover plate 4 can be fixed and used again. Thus, after the lower edge of the mold tube 3 is worn at the opening, the direction can be adjusted and it can continue to be used. When one end of the mold tube is worn and cannot be used, the front and rear ends of the mold tube 3 can be swapped to continue to be used, thereby enhancing durability.

[0027] Specifically, the bottom surface of the mold base cover plate 4 is provided with a plurality of connecting parts 8, the mold base 2 is provided with connecting grooves 9 corresponding to the plurality of connecting parts 8, the connecting parts 8 and the mold base 2 are provided with corresponding screw holes, and the mold base 2 and the connecting parts 8 are fixed together by screws 10; in this embodiment, by setting the connecting parts 8 and the connecting grooves 9, and cooperating with the screws 10, the mold base cover plate 4 can be fixed on the mold base 2 and can be disassembled.

[0028] Specifically, the mold base 2 is provided with limiting grooves 11 on both sides, and the mold base cover plate 4 is provided with limiting plates 12 on both sides; in this embodiment, the stability of the mold base cover plate 4 covering the mold base 2 is further improved by the cooperation of the limiting grooves 11 and the limiting plates 12.

[0029] Specifically, the shearing mechanism includes a shearing cylinder 13 and a cutter 14. The shearing cylinder 13 is fixed on the frame 15 and faces downward. A connecting plate 16 is fixed to the piston rod end of the shearing cylinder 13. The cutter 14 is fixed below the connecting plate 16 and is located on the front side of the mold base 2. In this embodiment, the copper-clad steel long material passes through the circular groove of the mold tube 3. After the front end protrudes to a set length, the shearing cylinder 13 drives the connecting plate 16 to descend. When the connecting plate 16 descends, the cutter 14 descends to complete the shearing of the copper-clad steel long material.

[0030] Specifically, the bottom surface of the connecting plate 16 is provided with a guide post 17, and the mold base 2 is provided with a guide hole 18 corresponding to the guide post 17. The guide post 17 is covered with a buffer spring 19. In this embodiment, when the connecting plate 16 descends, the guide post 17 extends into the guide hole 18 for guidance and positioning, and the buffer spring 19 provides buffering.

[0031] Specifically, the inner walls of the front and rear ports of the mold tube 3 are provided with annular grooves, and elastic rings 20 are fixed in the annular grooves; in this embodiment, the surface of the copper-clad steel long material can be cleaned and debris removed by setting the elastic rings 20.

[0032] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0033] Working principle: During processing, a circular groove is formed inside the mold tube 3. The inner diameter of the groove is designed to match the outer diameter of the copper-clad steel. The copper-clad steel long material passes through the circular groove of the mold tube 3. After the front end protrudes to a set length, the shearing cylinder 13 drives the connecting plate 16 to descend. When the connecting plate 16 descends, the guide post 17 extends into the guide hole 18 for guidance and positioning. The buffer spring 19 provides buffering. The cutter 14 descends to complete the shearing of the copper-clad steel long material. Then, the shearing cylinder 13 drives the cutter 14 to rise and reset. The same principle is used to cycle and complete the continuous fixed-length shearing of the copper-clad steel long material.

[0034] Because the mold tube 3 can prevent the copper-clad steel long material from rubbing against the mold base 2 when entering and exiting the circular groove, and because the mold tube 3 can be replaced by unscrewing the screw 10 to open the mold base cover plate 4, the mold tube 3 can be removed and replaced, avoiding the need to replace the entire mold base 2 after the circular groove is worn; at the same time, the lower edge of the front circular groove is easily worn during the stamping and shearing of copper-clad steel. After the lower edge is worn, the mold tube 3 can be rotated in the positioning groove 5 by opening the mold base cover plate 4. Since the polyhedral part 6 and the polyhedral groove 7 can still be positioned after rotation, the mold base cover plate 4 can be fixed and used again. Thus, after the lower edge of the mold tube 3 is worn at the opening, the direction can be adjusted and it can continue to be used. When one end edge is worn and cannot be used, the front and rear ends of the mold tube 3 can be swapped to continue to be used, thus enhancing durability.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
