Description

Technical Field

[0001] This utility model belongs to the technical field of cutting devices, and particularly relates to an oxygen-free copper rod cutting device. Background Technology

[0002] Copper is widely used in the power and electronics industries due to its excellent electrical conductivity. However, the copper rod cutting devices currently used generally utilize the lever principle, using a handle to drive the blade to cut the copper rod. This not only requires manual operation but is also inefficient. Even though some automatic cutting machines have emerged, they are generally complex in structure and expensive.

[0003] Because oxygen-free copper rods are small in diameter and cylindrical in shape, they are difficult to fix. Currently, cutting devices on the market can only be used for oxygen-free copper rods with a fixed diameter, which makes the copper rods prone to shifting during the cutting process, resulting in uneven cut surfaces.

A bottom pad for use with the top pad is connected to the inner wall of the placement groove. The inner side wall of the pressure plate is connected to the placement plate through a locking mechanism.

[0006] As a preferred embodiment of the above technical solution, the locking mechanism includes a Y-shaped groove formed on the side wall of the pressure plate, and a limiting block is inserted into the Y-shaped groove. The limiting block is connected to the side pull plate, and the bottom end of the side pull plate is connected to the second slider.

[0007] As a preferred embodiment of the above technical solution, the top of the side pull plate is connected to a limiting plate, and the bottom of the limiting plate abuts against the outer wall of the pressure plate.

[0008] As a preferred embodiment of the above technical solution, the limiting mechanism includes a connecting rod connected to the top of the connecting block, with the top of the connecting rod penetrating the outer wall of the pressure plate.

The second slot is formed on the pressure plate, and two sets of third sliders are connected to second elastic members on their outer walls, with the middle part of the second elastic member surrounding the second slide rail.

[0018] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] This application addresses the problem of positional displacement of copper rods during the cutting process in the prior art by setting a limiting mechanism on the pressure plate 7. This mechanism can longitudinally limit copper rods of different diameters under the wrapping effect of the top pad 4 and the bottom pad 3. Furthermore, the wrapping effect of the top pad 4 and the bottom pad 3 also limits the transverse movement of the copper rods, thereby ensuring the position of the copper rods during the cutting process and resulting in a smooth cut surface.

[0020] like Figure 1 As shown in the figure, in this embodiment of the present invention, the oxygen-free copper rod cutting device includes a placement plate 1; in the prior art, a cutting device is provided at the rear end of the placement plate 1, which is not shown in the figure. Figure 1 This application mainly describes the limiting mechanism provided on the placement plate 1 of the copper rod, which is far away from the cutting device during the cutting process, as mentioned in the background art. The cutting device in this solution is a direct reference to the prior art, and will not be described in detail here.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a placement slot 2 is provided on the placement plate 1, and a pressure plate 7 is connected to the placement plate 1 outside the placement slot 2. A connecting block 5 is connected to the pressure plate 7 through a limiting mechanism, and a top pad 4 is connected to the bottom end of the connecting block 5. A bottom pad 3 for use with the top pad 4 is connected to the inner wall of the placement slot 2. The inner side wall of the pressure plate 7 is connected to the placement plate 1 through a locking mechanism. Under the action of the special shape of the placement slot 2 and the pressure plate 7, the oxygen-free copper rod is initially limited, and at the same time, the bottom pad 3 and the top pad 4 are... Under the squeezing and wrapping action, the oxygen-free copper rod is further limited; the locking mechanism includes a Y-shaped groove 11 opened on the side wall of the pressure plate 7, and a limiting block 10 is inserted into the Y-shaped groove 11. The limiting block 10 is connected to the side pull plate 13. The bottom end of the side pull plate 13 is connected to the second slider 14. The second slider 14 slides on the outer wall of the first slide rod 15. The first slide rod 15 is connected in the first slot 17. The first slot 17 is opened on the placement plate 1. The outer wall of the second slider 14 is connected to A first elastic element 16 is provided, with its other end connected to the first slot 17. The middle part of the first elastic element 16 surrounds the outer wall of the first slide rod 15. Under the insertion action of the limiting block 10 and the Y-shaped slot 11, the pressure plate 7 is positioned on the placement plate 1. When it is necessary to open the pressure plate 7, the sliding action of the second slider 14 and the first slide rod 15, combined with the elastic potential energy of the first elastic element 16, pulls the side pull plate 13 outward, bringing the limiting block 10 out of the Y-shaped slot 17. The locking state can be released within the groove 11; the top of the side pull plate 13 is connected to the limiting plate 12, and the bottom end of the limiting plate 12 abuts against the outer wall of the pressure plate 7; under the pressure of the limiting plate 12, the potential energy can complete the limiting effect on the pressure plate 7 from the vertical state; a soft pad 18 is glued to the bottom end of the pressure plate 7, and the bottom end of the soft pad 18 abuts against the placement plate 1; under the protection of the soft pad 18, the contact surface between the pressure plate 7 and the placement plate 1 is buffered to avoid direct contact and collision damage.

[0022] like Figure 1 and Figure 3As shown, the limiting mechanism includes a connecting rod 19 connected to the top of the connecting block 5, with the top of the connecting rod 19 penetrating the outer wall of the pressure plate 7. Limiting grooves 20 are equidistantly formed on the outer wall of the connecting rod 19. A limiting rod 21 is inserted into one of the limiting grooves 20. The limiting rod 21 is connected to a side pull rod 22, and the bottom end of the side pull rod 22 is connected to a third slider 23. The third slider 23 slides on the outer wall of a second slide rail 24. The second slide rail 24 is connected to a second slot 26, which is formed on the pressure plate 7. Second elastic elements 25 are connected to the outer walls of two sets of third sliders 23, with the middle part of the second elastic element 25 surrounding the second slide rail 24. By interlocking the limiting rod 21 with the limiting grooves 20 at different positions, the limiting operation for oxygen-free copper rods of different diameters is completed. When it is necessary to adjust the insertion position of the limiting rod 21... The sliding action of the third slider 23 and the second slide rail 24, combined with the elastic potential energy of the second elastic element 25, compresses the two sets of side pull rods 22 towards each other. After the outer side of the limiting rod 21 is disengaged from the insertion state between it and the limiting groove 20, the connecting rod 19 is pushed downward. After the top pad 4, bottom pad 3 and oxygen-free copper rod form a limit, the side pull rod 22 is released. With the elastic reaction force of the second elastic element 25, the limiting rod 21 is pushed into the limiting groove 20 at the corresponding position. The outer wall of the connecting block 5 is connected to the first slider 8, and the outer side of the first slider 8 slides in the slide rail 9. The slide rail 9 is symmetrically opened on the inner wall of the cavity 6. The cavity 6 is opened at the bottom end of the pressure plate 7. Under the sliding action of the first slider 8 and the slide rail 9, the connecting block 5 can move up and down smoothly in the cavity 6.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
