Abstract

This utility model relates to the field of resistance wire processing technology, specifically an integrated straightening and cutting device for resistance wire processing, including a worktable, mounting slots, a rotary motor, a drive shaft, rotary rollers, a straightening cylinder, and a fixing frame. In this integrated straightening and cutting device for resistance wire processing, the rotary motors in the mounting slots at both ends of the top of the worktable are started. The drive shaft at its output end drives the rotary rollers and the straightening cylinder on its outer surface to rotate synchronously. When the resistance wire enters the range of the straightening cylinder, the rotating straightening cylinder exerts a continuous squeezing and guiding force on the resistance wire, gradually straightening the bent resistance wire into a straight state.

Through the above design, the straightening efficiency of the device is improved.

Description

Technical Field

[0001] This utility model relates to the field of resistance wire processing technology, specifically to an integrated straightening and cutting device for resistance wire processing. Background Technology

[0002] A resistance wire is an electrical component that converts electrical energy into internal energy. Generally speaking, the resistance of a metal increases with rising temperature; however, this is not the case for carbon, semiconductors, or electrolytes. Their resistance decreases with rising temperature. Thus, within a certain temperature range, we can assume a linear relationship between temperature change and resistance change, and therefore, we can convert temperature change into resistance change.

[0003] Traditional resistance wire straightening relies on manual straightening with the aid of tools, followed by cutting, which is inefficient and lacks precision. To address this, we propose an integrated straightening and cutting device for resistance wire processing. Utility Model Content

[0004] The purpose of this invention is to provide an integrated straightening and cutting device for resistance wire processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An integrated straightening and cutting device for resistance wire processing includes a worktable, mounting slots, a rotary motor, a drive shaft, a rotary roller, a straightening cylinder, and a fixing frame. The worktable has mounting slots at both ends of its top. A rotary motor is fixedly installed inside the mounting slots. A drive shaft is fixedly installed at the output end of the rotary motor. A rotary roller is fixedly installed on the top of the drive shaft. A straightening cylinder is fixedly installed on the outer surface of the rotary roller. A fixing frame is fixedly installed at both ends of the top of the worktable, and the fixing frame is located on one side of the straightening cylinder.

[0006] The top of the fixing frame is fixedly provided with a fixing block, and the fixing block is rotatably connected to a rotating shaft.

[0007] The outer surface of the rotating shaft is fixedly connected to a conveying roller, which is horizontally distributed, and the top of the worktable is provided with a cutting groove.

[0008] The cutting groove is equipped with a servo motor, and the output end of the servo motor is equipped with a bidirectional lead screw.

[0009] One end of the bidirectional lead screw is rotatably connected to the inside of the cutting groove, and a slider is threaded onto the outer surface of the bidirectional lead screw.

[0010] The top of the slider is fixedly provided with a column, and a cutting blade is fixedly provided on one side of the column.

[0011] The bidirectional lead screw has a limit ring fixedly installed in the middle, a controller is fixedly installed on one side of the worktable, a support platform is fixedly installed at the bottom of the worktable, and support columns are fixedly installed at the four corners of the bottom of the support platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This integrated straightening and cutting device for resistance wire processing firstly starts the rotary motor installed in the slots at both ends of the top of the worktable. The drive shaft at its output end drives the rotary roller and the straightening cylinder on the outer surface to rotate synchronously. When the resistance wire enters the range of the straightening cylinder, the rotating straightening cylinder exerts a continuous squeezing and guiding force on the resistance wire, gradually straightening the bent resistance wire into a straight state. At the same time, the straightened resistance wire is relayed by the conveying roller. The rotating shaft in the fixed block at the top of the fixed frame drives the conveying roller to rotate. The horizontally distributed conveying rollers, through friction with the resistance wire, smoothly transport the straightened resistance wire to the cutting position, preparing it for the subsequent cutting process. Through the above design, the straightening efficiency of the device is improved.

[0013] 2. This integrated straightening and cutting device for resistance wire processing controls the cutting mechanism according to preset parameters. When the resistance wire is fed to the set length, the servo motor in the cutting groove starts, and the bidirectional lead screw at its output end rotates accordingly. Since the threads at both ends of the bidirectional lead screw are opposite, the slider connected by the threads on the outer surface drives the top column and the cutting blade to move synchronously towards the center. The cutting blades on both sides cooperate to complete the cutting operation of the resistance wire. The limiting ring in the middle of the bidirectional lead screw can prevent the cutting blade from colliding due to excessive movement of the slider. After cutting, the servo motor reverses, driving the cutting blade to reset, waiting for the next processing cycle. Through the above design, the cutting efficiency of the device is improved.

[0016] 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.

[0017] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: An integrated straightening and cutting device for resistance wire processing includes a worktable 1, a mounting groove 2, a rotary motor 3, a drive shaft 4, a rotary roller 5, a straightening cylinder 6, and a fixing frame 7. The worktable 1 has mounting grooves 2 at both ends of its top. The rotary motor 3 is fixedly installed inside the mounting groove 2. The drive shaft 4 is fixedly installed at the output end of the rotary motor 3. The rotary roller 5 is fixedly installed on the top of the drive shaft 4. The straightening cylinder 6 is fixedly installed on the outer surface of the rotary roller 5. The fixing frame 7 is fixedly installed at both ends of the top of the worktable 1, and the fixing frame 7 is located on one side of the straightening cylinder 6.

[0018] The worktable 1 is typically made of high-strength cast iron or welded steel plate, with a surface ground to ensure flatness. It can withstand the weight of each component and the impact force during processing, providing a stable mounting base for the entire device. Its dimensions are designed according to the length of the processing resistance wire and the overall layout of the device. Mounting slots 2 are located at both ends of the top of the worktable 1. The slot dimensions match the rotary motor 3, and the inner wall is smooth, facilitating the installation and fixation of the rotary motor 3. It also provides some protection for the motor, reducing the impact of external dust and debris.

[0019] A fixing block 8 is fixedly installed on the top of the fixing frame 7. A rotating shaft 9 is rotatably connected inside the fixing block 8. A conveying roller 10 is fixedly connected to the outer surface of the rotating shaft 9. The conveying roller 10 is horizontally distributed. A cutting groove 11 is opened on the top of the worktable 1. A servo motor 12 is fixedly installed inside the cutting groove 11. A bidirectional lead screw 13 is fixedly installed at the output end of the servo motor 12. One end of the bidirectional lead screw 13 is rotatably connected to the inside of the cutting groove 11. A slider 14 is threadedly connected to the outer surface of the bidirectional lead screw 13. A column 15 is fixedly installed on the top of the slider 14. A cutting blade 16 is fixedly installed on one side of the column 15. A limit ring 17 is fixedly installed in the middle of the bidirectional lead screw 13. A controller 18 is fixedly installed on one side of the worktable 1. A support platform 19 is fixedly installed at the bottom of the worktable 1. Support columns 20 are fixedly installed at the four corners of the bottom of the support platform 19.

[0020] Servo motor 12 is a high-precision drive motor, a mature technology with accurate positioning and fast response. It achieves precise control via an encoder, accurately controlling the rotation angle of the bidirectional lead screw 13 according to the instructions of controller 18, thus ensuring the accuracy of the cutting length. The bidirectional lead screw 13 is made of high-strength alloy steel with precision-machined left and right-hand threads. The high thread precision and small clearance with the slider 14 ensure the smooth and accurate movement of the slider 14. Its length is determined by the maximum stroke of the cutting blade 16.

[0021] In this embodiment, the integrated straightening and cutting device for resistance wire processing operates as follows: First, the rotary motor 3, located in the mounting slots 2 at both ends of the top of the worktable 1, starts. Its output drive shaft 4 drives the rotary roller 5 and the straightening cylinder 6 on its outer surface to rotate synchronously. When the resistance wire enters the range of the straightening cylinder 6, the rotating cylinder 6 exerts a continuous squeezing and guiding force on the resistance wire, gradually straightening the bent resistance wire into a straight state. Simultaneously, the straightened resistance wire is relayed by the conveying roller 10. The rotating shaft 9 within the fixing block 8 at the top of the fixing frame 7 drives the conveying roller 10 to rotate. The horizontally distributed conveying roller 10, through friction with the resistance wire, smoothly conveys the straightened resistance wire to the cutting position, preparing it for the subsequent cutting process. Then, the controller 18 controls the cutting mechanism according to preset parameters. When the resistance wire is fed to the set length, the servo motor 12 in the cutting groove 11 starts, and the bidirectional lead screw 13 at its output end rotates accordingly. Since the threads at both ends of the bidirectional lead screw 13 are opposite, the slider 14 connected by the thread on the outer surface will drive the top column 15 and the cutting blade 16 to move synchronously towards the middle. The two cutting blades 16 cooperate with each other to complete the cutting operation of the resistance wire. The limiting ring 17 in the middle of the bidirectional lead screw 13 can prevent the slider 14 from moving excessively and causing the cutting blade 16 to collide. After the cutting is completed, the servo motor 12 reverses and drives the cutting blade 16 to reset, waiting for the next processing cycle.
