Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a heating wire anti-bending device provided with a swing folding mechanism. Background Art

[0002] Heating wire bending is usually done by bending a heating wire (such as an electric heating wire, a heating wire, etc.) into a specific shape to suit the design requirements of an electrical component or heater.

[0003] When existing bending machines bend metal wires, the wires are easily stretched during the bending process, which affects the bending effect of the metal wires.

[0004] In order to overcome the above-mentioned defects, the prior art (application number: CN216176126U) discloses a wire bending and forming machine, which drives the fixing rod and the bending wheel to move along the movable groove through the screw sleeve, and the bending wheel drives the wire to move. When the wire is bent, the two fixed toothed discs can rotate in opposite directions under the action of the ratchet and the movable clamping rod, thereby avoiding affecting the quality of the wire due to bending.

[0005] The above-mentioned existing technology prevents bending from affecting the quality of the wire by rotating the fixed toothed disk in opposite directions between the ratchet and the movable clamping rod. In actual use, when the bending machine bends the wire, the wire is generally repeatedly bent and rotated through the bending mechanism to achieve continuous bending of the wire. The repeated bending and rotation results in a low bending efficiency of the bending machine for the wire. Summary of the Invention

[0030] A motion box 11 is fixedly connected to the outside of the mounting rod 10, and two symmetrically distributed pulleys 12 are rotatably connected inside the motion box 11. A mounting groove 13 with a semicircular cross-section is provided in the middle of the outer side of the pulley 12. Two symmetrically distributed mounting rings are fixedly connected to both sides of the bottom of the motion box 11, and the motion box 11 is fixedly connected to the outside of the mounting rod 10 through the mounting rings.

[0031] A ratchet structure is provided between the two pulleys 12 and the motion box 11 , and a heating wire is engaged and connected between the two pulleys 12 , and the heating wire is located between two semicircular mounting grooves 13 .

[0032] A mounting sleeve 14 is fixedly connected to the side of the top of the mounting box 1 away from the pulley 12, and two symmetrically distributed hydraulic rods 15 are fixedly connected to the top of the mounting sleeve 14. The telescopic ends of the two hydraulic rods 15 pass through the top of the mounting sleeve 14 and extend into the inside of the mounting sleeve 14, and the telescopic ends of the hydraulic rods 15 are fixedly connected to a lower pressure block 16.

[0033] Positioning rods 17 are provided at both ends of the bottom of the material transport plate 2 and the bottom of the turntable 4, and the three positioning rods 17 are fixedly connected to the outside of the mounting sleeve 14 and the two ends of the pulley 12, and the outsides of the three positioning rods 17 are slidably connected to the inside of the three positioning sleeves 9 respectively.

[0034] An S-shaped heating wire is arranged inside the mounting sleeve 14, and the outer side of the lower pressing block 16 is engaged with the bending part of the heating wire, and the annular structure distributed in an annular shape on the outer side of the lower pressing block 16 and the bottom of the mounting sleeve 14 form a clamping state for the heating wire. Example 2:

[0035] Based on the first embodiment, the specific working principle is as follows:

[0036] The heating wire anti-bending device is provided with a swinging folding mechanism. During the bending process of the heating wire, the heating wire needs to pass between the two pulleys 12 inside the moving box 11. Since a ratchet structure is provided between the moving box 11 and the pulley 12, the heating wire can only move inside the two pulleys 12 toward the inside of the mounting sleeve 14. The heating wire is engaged with the lower pressing block 16 by transporting the heating wire to the inside of the mounting sleeve 14, and the bending effect of the heating wire is completed by the movement of the moving box 11. In this process, the moving box 11 reciprocates between the material transport plate 2 and the mounting sleeve 14 toward their two ends, so that the moving box 11 and the lower pressing block 16 are periodically misaligned, thereby realizing the bending of the heating wire.

[0037] When the moving box 11 reciprocates on the outside of the positioning rod 17 toward its two ends, the power is transmitted to the reducer 6 through the motor 7, and the reducer 6 drives the turntable 4 to rotate, so that the turntable 4 drives the eccentric shaft 5 to rotate around its center. At this time, the eccentric shaft 5 will drive the moving rod 8 to reciprocate on the top of the turntable 4 along the vertical direction of its center through the opening in the middle of the moving rod 8. When the moving rod 8 rotates, it will drive the positioning sleeves 9 at its two ends and at both ends of the mounting rod 10 to slide on the outside of the positioning rod 17, and then the moving rod 8 drives the moving box 11 to move through the mounting rod 10. Compared with the traditional bending machine that performs multiple-section bending of the wire through the rotating structure, after the moving box 11 completes a cycle of reciprocating motion, the heating wire is bent twice through the cooperation between the moving box 11 and the lower pressing block 16, thereby improving the efficiency of bending the heating wire;

[0038] The heating wire is transported through the limiting ring on the top of the transport plate 2 by the feeding mechanism until the heating wire is located between the mounting grooves 13 on the outside of the two pulleys 12. The heating wire is fixedly clamped by the fitting of the mounting grooves 13 and the outside of the heating wire. The motion box 11 is driven by the motion rod 8 to move to the end of the mounting sleeve 14. At this time, the heating wire is driven by the feeding mechanism to move between the two pulleys 12 toward the inside of the mounting sleeve 14 until the heating wire moves to the side of the lower pressing block 16 away from the center of the mounting sleeve 14. At this time, the hydraulic rod 15 is driven to extend so that the annular structure distributed on the outside of the lower pressing block 16 and the bottom of the mounting sleeve 14 clamp the end of the heating wire. At this time, the motion box 11 is driven by the motion rod 8 to move away from the lower pressing block 16 in the clamping state. During the movement of the motion box 11, the heating wire is in an extended state, so that the motion box When moving, 11 adjusts its shape to a turntable parallel to the mounting sleeve 14 until the moving box 11 moves to one end of the lower pressing block 16 in the mounting sleeve 14 away from the clamping state. At this time, the clamping state lower pressing block 16 and the heating wire are separated from each other, and the bent heating wire is moved to the outside of the mounting sleeve 14. During the movement of the moving box 11, the heating wire forms a fillet between the two pulleys 12 inside the moving box 11, and the fillet formed by the heating wire is moved to the bottom of the lower pressing block 16 close to the moving box 11 until the lower pressing block 16 and the mounting sleeve 14 engage the fillet, and at the same time drive the moving box 11 in the direction away from the fillet. When the moving box 11 moves away from the fillet, the heating wire rotates outside the lower pressing block 16 to form a complete fillet. Repeat this process to complete the bending process of the heating wire.
