However, during the production process of resistance wires, the problem of bent shapes often occurs. Therefore, it is necessary to shape them before cutting. In the prior art, the shaping only presses on them to solve the problem of upward bending, but they may also bend left and right, and such problems have not been solved. Therefore, we have proposed an alloy resistance wire shaping and cutting device with high straightness.

[0003] The prior art discloses a resistance wire shaping and cutting device with the application number: CN202321469824.4.

[0004] The prior art shapes and straightens the resistance wire, but only the shaping block presses on the resistance wire. In this way, the upward-bent resistance wire can be flattened, but the resistance wire bent left and right cannot be taken into account, and precise cutting is difficult to achieve.

[0005] Therefore, it is very necessary to design an alloy resistance wire shaping and cutting device with strong practicability and high straightness. Summary of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6, the present utility model provides a technical solution: an alloy resistance wire shaping and cutting device, including a shaping table 1, a motor 2 is fixedly connected to one side of the shaping table 1, a rotating shaft 21 is arranged at the output end of the motor 2, a reciprocating mechanism is connected to one side of the rotating shaft 21, a first cylinder 3 is fixedly connected to the inner top of the shaping table 1, a first piston rod 31 is connected to the output end of the first cylinder 3, a shaping block 32 is connected to one side of the first piston rod 31, a plurality of grooves 33 are formed at the bottom of the shaping block 32, the shaping block 32 is connected to the reciprocating mechanism, a cutting table 4 is arranged on one side of the shaping table 1, a second cylinder 5 is fixedly connected to the inner top of the cutting table 4, a second piston rod 51 is connected to the output end of the second cylinder 5, a disassembly and assembly mechanism is connected to one side of the second piston rod 51, a cutting knife is corresponding to one side of the disassembly and assembly mechanism, and a conveyor belt 6 is arranged on one side of the cutting table 4; when the staff is ready to start the cutting work, first place the tape formed by the bent resistance wire (alloy resistance wire in the shape of M, U, etc.) on the conveyor belt 6, and the pin part of the resistance wire will leak outside the tape, which is convenient for shaping and cutting. When it is conveyed to the bottom of the shaping block 32, the conveying pauses. The staff turns on the first cylinder 3, and the first piston rod 31 at the output end moves downward, driving the shaping block 32 downward, and partially pressing on the surface of the resistance wire. Then the staff turns on the motor 2, and the rotating shaft 21 at the output end rotates, and the reciprocating mechanism moves left and right, driving the shaping block 32 to move back and forth a small distance. When pressing down at the beginning, the pin part of the resistance wire may bend upward or left and right, that is, it is not straight. When the shaping block 32 presses down, it can flatten the upward bend. When the reciprocating mechanism moves left and right, the shaping block 32 moves left and right a small distance to receive the left and right bent pins into the grooves 33, so as to realize its shaping. Then the shaping block 32 moves upward, and the conveyor belt 6 continues to send the resistance wire to the bottom of the cutting knife, and its pins can be cut. The cutting knife can be easily disassembled and assembled through the disassembly and assembly mechanism, which is convenient for replacement and reduces the labor force. By setting a reciprocating mechanism, the left and right bent resistance wires can be inducted into the grooves 33 by moving left and right a small distance, so as to realize its shaping and improve the overall accuracy. By setting a disassembly and assembly mechanism, it is convenient and fast to replace the cutting knife, reducing the labor intensity of the staff.

[0027] A first support block 12 is fixedly connected to one side of the shaping table 1, a second support block 41 is fixedly connected to one side of the cutting table 4, and the first support block 12 and the second support block 41 correspond to the conveyor belt 6; the first support block 12 mainly provides a certain supporting force when the shaping block 32 presses down. The first support block 12 is at the bottom of the upper layer of the conveyor belt 6 and does not affect the operation of the conveyor belt 6. Similarly, the second support block 41 provides a certain supporting force during cutting, and its position is the same as that of the first support block 12, at the bottom of the upper layer of the conveyor belt 6.

[0028] The reciprocating mechanism includes a special-shaped block 22, and the rotating shaft 21 is fixedly connected to the special-shaped block 22. One side of the shaping table 1 is fixedly connected with a bent block 11. A moving rod 24 is slidably connected inside the bent block 11. Two convex blocks 23 are rotatably connected to the bottom of the moving rod 24. The special-shaped block 22 is located between the two convex blocks 23, and the moving rod 24 is connected to the shaping block 32. When the staff turns on the motor 2, the rotating shaft 21 at the output end rotates, and the special-shaped block 22 rotates. Since the convex block 23 and the moving rod 24 are rotatably connected, when the special-shaped block 22 rotates, the two convex blocks 23 will also rotate, mainly to reduce the friction between them. The special-shaped block 22 has a feature that the areas of its two parts are different. Taking the connection with the rotating shaft 21 as the demarcation line, when the special-shaped block 22 rotates, when the large-area part moves to the left, it pushes the left convex block 23 to the left, and the right convex block 23 also moves to the left accordingly. In this way, the moving rod 24 moves to the left. Similarly, it can also move to the right, thus realizing the left and right reciprocating movement of the moving rod 24, a small-distance movement, so that the shaping block 32 can move left and right, thereby realizing the shaping of the resistance wire. By setting the reciprocating mechanism, the resistance wire can be adjusted into the groove 33 and effectively straightened. This design ensures that the resistance wire maintains a stable position during the shaping process, avoiding movement or deviation during the straightening process, thereby improving the accuracy and efficiency of straightening.

[0029] The moving rod 24 and the shaping block 32 are slidably connected, and the first piston rod 31 and the shaping block 32 are slidably connected. The moving rod 24 and the shaping block 32 are slidably connected in the up and down direction, so that their connection does not affect the lifting of the shaping block 32. The first piston rod 31 and the shaping block 32 are slidably connected in the left and right direction, so that the reciprocating mechanism can also drive the shaping block 32 to move left and right. When the motor 2 stops, the reciprocating mechanism temporarily stops moving, and the shaping block 32 also stops moving accordingly, and the whole is still relatively stable.

[0030] The special-shaped block 22 is a combination of an elliptical block and a circular block. The connection between the rotating shaft 21 and the special-shaped block 22 is located at the circular block of the special-shaped block 22. The special-shaped block 22 is in the shape of a combination of an elliptical block and a small semi-circular block. The area of the elliptical block part is large, and the area of the circular block part is small. The rotating shaft 21 is connected to the circular block part. In this way, when the rotating shaft 21 rotates, the special-shaped block 22 has changes in area at different positions, thereby realizing left and right reciprocating movement.

[0031] The disassembly and assembly mechanism includes a square block 52. The square block 52 and the second piston rod 51 are fixedly connected. A circular groove 53 is formed inside the square block 52. A thin rod 55 is rotatably connected inside the square block 52. An L-shaped block 54 is rotatably connected to one side of the square block 52. A notch 57 is formed inside the L-shaped block 54. The thin rod 55 passes through the notch 57. One end of the thin rod 55 is connected with a rotating block 56. An arc-shaped block 58 is fixedly connected to one side of the L-shaped block 54. The arc-shaped block 58 corresponds to the cutting knife. When the staff is ready to fix the cutting knife, the upper part of the cutting knife is cylindrical and is also fixedly connected with a circular ring, which just matches the shape of the circular groove 53. The staff places the upper end of the cutting knife inside the circular groove 53, and then rotates the L-shaped block 54 so that the arc-shaped block 58 is in the horizontal direction and just adheres to the outside of the top of the cutting knife. Then rotate the rotating block 56. When the rotating block 56 rotates, it will move upward along the thin rod 55. In this way, the rotating block 56 can press and fix the L-shaped block 54, and at the same time, the thin rod 55 will also be fixed. When it needs to be disassembled, just rotate the rotating block 56 in the reverse direction. By setting the disassembly and assembly mechanism, through simple rotation, the rapid fixation and disassembly of the cutting knife can be realized, greatly improving the work efficiency and the convenience of operation.

[0032] Threads are provided on the outer side of the thin rod 55, and the thin rod 55 and the rotating block 56 are threadedly connected. Because the thin rod 55 and the rotating block 56 are threadedly connected, when the rotating block 56 rotates, by controlling the rotation direction, it can rotate upward or downward on the thin rod 55, so as to realize fixation and disassembly.

[0033] A circular ring groove is formed in the middle of the circular groove 53. The circular ring groove just corresponds to the circular ring at the upper end of the cutting knife, so that the upper end of the cutting knife can just be stuck into the circular groove 53, further ensuring stability.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
