Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to an electrothermal high-temperature alloy wire cutting device. Background Technology

[0002] Cutting equipment technology is a technique that uses mechanical methods, such as heating, to precisely cut materials like metal wires into the required lengths. Cutting electrothermal high-temperature alloy wires is used to meet the specific length requirements of different applications, such as industrial heating equipment and domestic heating appliances.

[0003] Under current conditions, a common method is to use an electrothermal high-temperature alloy wire cutting device, as disclosed in CN212310711U, which includes a support base and a base, with the support base located on one side of the top of the base. By adding a first reinforcing plate to the front surface of the force-bearing block, the connection between the force-bearing block and the rotating block is effectively improved. However, this device only has one through-slot and one shearing mechanism, allowing for the cutting of only one alloy wire at a time, resulting in low production efficiency. Relying solely on mechanical force for shearing requires extremely high shearing force for high-strength electrothermal high-temperature alloy wires, leading to high energy consumption, low efficiency, and severe wear on the cutter head. Simply using a protective sleeve for the alloy wire provides insufficient stability and control during feeding, easily causing the alloy wire to wobble or deviate. Utility Model Content

[0004] The purpose of this invention is to solve the problem of the difficulty in cutting high-temperature alloy wires in the prior art, and to propose an electrothermal high-temperature alloy wire cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature alloy wire cutting device includes a worktable with legs, an electric heater for heating the alloy wire is fixedly installed on the worktable, and the electric heater has three feed inlets and three discharge outlets. A support frame is fixedly installed on one side of the worktable, and three cutting blades for cutting the alloy wire are installed on the support frame through a driving component. The worktable is provided with two limiting structures to limit the alloy wire. Two symmetrically arranged rotating screws are rotatably installed on the worktable, and receiving frames are slidably sleeved on the two rotating screws. The receiving frames are provided with threaded holes corresponding to the rotating screws, and three receiving seats corresponding to the cutting head are fixedly installed on the receiving frames.

[0006] Preferably, the support frame has an L-shaped structure, the cutting head has a trapezoidal structure, the upper end of the receiving seat has a V-shaped structure, and the receiving seat has a guide hole for guiding the cutting head.

[0007] Preferably, the driving component includes a lifting rod that is slidably sleeved on the support frame and integrally connected to the cutting head, a fixed frame is fixedly installed on the electric heater, and a drive shaft is rotatably installed on the fixed frame. An eccentric wheel is fixedly installed on the drive shaft, and a drive block integrally connected to the lifting rod is slidably sleeved on the eccentric wheel.

[0008] Preferably, the eccentric wheel has a limiting groove for limiting the position of the drive block, and the drive block has a cylindrical structure.

[0009] Preferably, the limiting structure includes two limiting frames fixedly installed on the workbench, and two sets of lifting blocks are slidably sleeved inside the limiting frames. A spring is welded between the lifting blocks and the limiting frames, and a limiting roller for limiting the metal wire is placed between the two lifting blocks.

[0010] Preferably, the limiting frame has a U-shaped structure, and the limiting roller has three evenly distributed limiting grooves that correspond to the feed inlet of the electric heater.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model, by setting three feed ports, discharge ports, cutting heads and corresponding receiving seats, simultaneously heats and cuts three alloy wires, which helps to improve the efficiency of cutting operations. The electric heater locally heats and softens the high-strength, high-toughness high-temperature alloy wires before cutting, making it easier for the cutting head to cut. The drive shaft drives the eccentric wheel to rotate, and the drive block drives the lifting rod and the cutting head to move up and down reciprocally, realizing automated cutting.

[0012] 2. This utility model adjusts the position of the receiving seat by rotating the lead screw and the receiving frame to adapt to the cutting requirements of alloy wires of different lengths. The receiving seat limits the alloy wire to prevent it from deviating when it comes into contact with the cutting head. The lifting block and the limiting roller cooperate to elastically clamp and limit the alloy wire to ensure that it does not deviate when it is fed. It adapts to the limiting requirements of alloy wires of different diameters and prevents the alloy wire from shaking during the feeding process, which would affect the cutting accuracy.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A high-temperature alloy wire cutting device includes a worktable 1 with legs, a controller on the worktable 1, and an electric heater 2 for heating the alloy wire fixedly installed on the worktable 1. The electric heater 2 is electrically connected to the controller and has three feed inlets and three discharge outlets.

[0017] A support frame 3 is fixedly installed on one side of the workbench 1, and three cutting blades 5 for cutting alloy wires are installed on the support frame 3 via a drive component. Please refer to the instruction manual for details. Figure 1 The positions of the three cutting heads 5 correspond to the three discharge ports of the electric heater 2, ensuring accurate connection and cutting operation after the alloy wire is heated. The drive unit drives the eccentric wheel 8 to rotate through the drive shaft 7, and pushes the lifting rod 4 and the cutting head 5 to move up and down with the help of the drive block 9, so as to realize the automatic cutting of multiple heated alloy wires.

[0018] The workbench 1 is equipped with two limiting structures for limiting the alloy wire. The two limiting structures are respectively set at the feed end and the discharge end of the electric heater 2 to form a bidirectional limiting to prevent the alloy wire from deviating during feeding and heating. Two symmetrically arranged rotating screws 10 are rotatably installed on the workbench 1, and a receiving frame 11 is slidably sleeved on the two rotating screws 10. The receiving frame 11 has threaded holes corresponding to the rotating screws 10. Three receiving seats 12 corresponding to the cutting head 5 are fixedly installed on the receiving frame 11.

[0019] The support frame 3 has an L-shaped structure, and the cutting head 5 has a trapezoidal structure. The trapezoidal structure has a high blade sharpness, which reduces the compressive stress on the alloy wire during cutting and improves the flatness of the cut surface. The upper end of the receiving seat 12 has a V-shaped structure, which is suitable for alloy wires of different diameters and improves the limiting effect on the alloy wire. The receiving seat 12 has a guide hole for guiding the cutting head 5. The diameter of the guide hole matches the size of the cutting head 5 to ensure that the cutting head 5 does not deviate when moving up and down, thus improving the cutting accuracy.

[0020] The driving component includes a lifting rod 4 that is slidably sleeved on the support frame 3 and integrally connected to the cutting head 5; a fixed frame 6 is fixedly installed on the electric heater 2; a drive shaft 7 is rotatably installed on the fixed frame 6; and a motor that is connected to the drive shaft 7 and electrically connected to the controller is fixedly installed on the fixed frame 6.

[0021] An eccentric wheel 8 is fixedly mounted on the drive shaft 7. A drive block 9, which is integrally connected to the lifting rod 4, is slidably sleeved on the eccentric wheel 8. See the attached instruction manual for details. Figure 3 When the eccentric wheel 8 rotates, it pushes the lifting rod 4 up and down through the drive block 9, thereby driving the cutting head 5 to complete the cutting action.

[0022] The eccentric wheel 8 has a limiting groove for limiting the position of the drive block 9. The drive block 9 has a cylindrical structure. Please refer to the instruction manual for details. Figure 2 The cylindrical structure fits tightly against the inner wall of the limiting groove, ensuring the stability of power transmission while reducing contact wear.

[0023] The limiting structure includes two limiting frames 13 fixedly installed on the workbench 1, and two sets of lifting blocks 14 are slidably sleeved inside the limiting frames 13. Springs 15 are welded between the lifting blocks 14 and the limiting frames 13. A limiting roller 16 for limiting the metal wire is placed between the two lifting blocks 14. For details, please refer to the attached instruction manual. Figure 4 The limiting roller 16 rotates freely, reducing the frictional resistance during alloy wire conveying. At the same time, under the action of the spring 15, the limiting roller 16 always keeps close to the surface of the alloy wire, achieving elastic clamping and limiting of the limiting roller 16.

[0024] The limiting frame 13 has a U-shaped structure. The limiting roller 16 has three evenly distributed limiting grooves that correspond to the feed inlet of the electric heater 2. The three limiting grooves correspond to the three alloy wires and independently limit each alloy wire to avoid mutual interference between multiple alloy wires and further improve the feeding stability.

[0025] It should be noted that the specific models and specifications of the controller, motor, and electric heater 2 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0026] The functional principle of this utility model can be explained through the following operation methods: Three alloy wires are passed through the two corresponding limiting rollers 16 respectively, and fed into the electric heater 2 through the three feed ports, and then discharged from the three discharge ports of the electric heater 2, passing through another set of two corresponding limiting rollers 16. According to the required cross-sectional size of the alloy wire, rotate the two rotating screws 10. The rotating screws 10 drive the receiving frame 11 to move. The receiving frame 11 drives the three receiving seats 12 fixedly installed on it to adjust to the specified position, so that the receiving seats 12 are close to the lower surface of the metal wire. The controller sends a start command to the electric heater 2, and the electric heater 2 locally heats and softens the alloy wire; During the alloy wire cutting process, the limiting roller 16 elastically clamps and limits the alloy wire, and the lifting block 14 drives the limiting roller 16 to closely adhere to the alloy wire under the action of the spring 15. The controller sends a start command to the motor, which drives the drive shaft 7 to rotate. The drive shaft 7 drives the eccentric wheel 8 to rotate. During the rotation, the eccentric wheel 8 restricts the inner wall of the groove from applying pressure to the drive block 9, so that the drive block 9 drives the lifting rod 4 to move. The lifting rod 4 drives the three cutting heads 5 connected to it to move. When the cutting head 5 moves downward, it cooperates with the receiving seat 12 to cut the alloy wire that has been heated and softened. After the cutting is completed, the cutting head 5 is reset upward under the action of the driving component, realizing the automated continuous cutting operation of three alloy wires.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
