Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire insulation cutting technology, specifically a wire insulation cutting device. Background Technology
[0002] The wire production line insulation cutting device is a special equipment used in the wire production process to cut the outer sheath (insulation layer) of wires. When it is necessary to completely strip off a section of wire insulation to expose the internal conductor (such as to make test leads or solder joints), the cutting device needs to cut the insulation layer along the wire axis, that is, along the length of the wire.
[0003] Since the insulation layer thickness of wires of different specifications usually varies, if the blade cuts too deep, it will directly cut the internal conductor. If the blade cuts too shallow, it will not be able to cut the insulation layer, resulting in incomplete stripping. The blade position of a typical cutting device is fixed or can only be adjusted manually. If the adjustment is incorrect, scrap will be produced. In particular, in multi-specification small-batch production, frequent machine adjustments can easily lead to batch defects. Utility Model Content
[0004] The purpose of this invention is to provide a wire production line sheath cutting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire production line sheath cutting device, comprising a cutting device body, a wire body, a cutting blade, and a wire feeding wheel. The wire feeding wheel is located at the bottom of the cutting device body, and a first drive motor is fixed to one side of the cutting device body. The output end of the first drive motor is connected to the wire feeding wheel via a rotating shaft. The wire body passes through the top of the wire feeding wheel. A blade holder is located inside the cutting device body above the wire feeding wheel. A cutting blade is mounted inside the blade holder via a roller, and pressure sensors are located at both ends of the roller. A controller is located at the top of one side of the cutting device body. A top frame is located at one end of the top of the cutting device body, and a lead screw is located on one side of the top frame. A drive block is sleeved on the lead screw, and one side of the drive block is connected to the blade holder via a connecting rod. A second drive motor is fixed to one end of the top of the top frame, and the output end of the second drive motor is connected to the lead screw.
[0006] Preferably, a guide rod is provided on the side of the top frame away from the lead screw, and the side of the connecting rod near the guide rod is slidably sleeved with the guide rod through a guide sleeve.
[0007] Preferably, the cutting device body is provided with limit frames on both sides, and the two ends inside the limit frames are provided with clamping wheels through brackets.
[0008] Preferably, the clamping wheels are in contact with both sides of the wire body, and the clamping wheels are made of polyurethane material.
[0009] Preferably, buffer cavities are provided on both sides inside the limiting frame, and pressure plates are uniformly arranged inside the buffer cavities through buffer springs, and the pressure plates are all connected to the bracket.
[0010] Preferably, a damping pad is provided on the side of the buffer cavity away from the pressure plate, and the damping pad is connected to the side of the buffer spring away from the pressure plate.
[0011] Preferably, the damping pad has a honeycomb porous structure, and all damping pads are made of rubber.
[0012] Preferably, limit blocks are provided on both sides of the blade holder, and limit grooves matching the limit blocks are provided on both sides of the interior of the cutting device body.
[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This wire production line sheath cutting device comprises a cutting device body, a wire body, a wire feeding wheel, a first drive motor, a blade holder, a cutting blade, a roller, a pressure sensor, a top frame, a lead screw, a drive block, and a second drive motor. The first drive motor drives the wire feeding wheel to rotate, feeding the wire body into the cutting device body at a uniform speed, ensuring the wire body moves smoothly along the axial direction. The second drive motor starts, driving the lead screw to rotate, which in turn drives the drive block mounted on the lead screw to move vertically, thereby pushing the blade holder to bring the cutting blade closer to the wire body. When the cutting blade contacts the wire sheath, the pressure sensor starts to detect the reaction force on the cutting blade and transmits the signal to the controller. The displacement of the cutting blade is controlled by the pressure value. If the pressure is less than a preset threshold, it indicates that the cutting blade has not cut in or the cutting depth is insufficient. The controller instructs the second drive motor to continue rotating, pushing the drive block further through the lead screw to increase the pressure between the cutting blade and the wire sheath. Conversely, the cutting blade rises, reducing the displacement. Pressure feedback prevents "incomplete cuts." Or "cutting the core wire", it is suitable for wire sheaths of different thicknesses. It can cope with working conditions such as uneven sheath thickness and changes in conveying speed, improve cutting consistency, and requires no manual intervention, reducing debugging time.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1-5 The present invention provides an embodiment of a wire production line sheath cutting device, comprising a cutting device body 1, a wire body 2, a cutting blade 9 and a wire feeding wheel 10. The wire feeding wheel 10 is provided at the bottom of the cutting device body 1, and a first drive motor 3 is fixed on one side of the cutting device body 1. The output end of the first drive motor 3 is connected to the wire feeding wheel 10 through a rotating shaft, and the top of the wire feeding wheel 10 passes through the wire body 2.
[0023] The first drive motor 3 starts and drives the wire feeding wheel 10 to rotate through the rotating shaft, feeding the wire body 2 into the bottom of the cutting device body 1 at a constant speed.
[0024] Both sides of the main body 1 of the cutting device are provided with limit frames 5, and both ends of the limit frame 5 are provided with clamping wheels 18 through brackets 19. The clamping wheels 18 are in contact with both sides of the main body 2 of the wire.
[0025] The clamping wheels 18 on both sides form a centered clamping, ensuring that the wire body 2 passes through the cutting position along the axial center line, and avoiding deviation of the cutting position due to the offset of the wire body 2.
[0026] The clamping wheels 18 are all made of polyurethane, which has high insulation to prevent short circuits during clamping; at the same time, the surface friction is high to prevent the wire body 2 from slipping during transportation.
[0027] Both sides of the limit frame 5 are provided with buffer cavities 20, and pressure plates 23 are evenly arranged inside the buffer cavities 20 through buffer springs 22. The pressure plates 23 are all connected to the bracket 19. The clamping wheel 18 can adapt to wires of different diameters and maintain clamping force through elastic deformation, without the need for manual replacement of clamps.
[0028] Damping pads 21 are provided on the side of the buffer cavity 20 away from the pressure plate 23, and the damping pads 21 are connected to the side of the buffer spring 22 away from the pressure plate 23.
[0029] When the conveying speed of the main body of the wire 2 fluctuates or the wire diameter changes, the buffer spring 22 can absorb the vibration of the bracket 19 and avoid the impact and squeezing of the clamping wheel 18 on the main body of the wire 2. The damping pad 21 can absorb the rigid impact when the buffer spring 22 is compressed to the limit, reduce the impact noise, and at the same time avoid the buffer spring 22 from being overloaded and damaged.
[0030] The damping pad 21 has a honeycomb porous structure and is made of rubber. When the porous structure is compressed, the deformation of the pore walls will convert mechanical energy into heat energy through internal friction of the material, which will significantly dissipate the impact energy.
[0031] A blade holder 8 is installed inside the main body 1 of the cutting device above the wire feeding wheel 10. A cutting blade 9 is installed inside the blade holder 8 via a roller 14. Pressure sensors 13 are installed at both ends of the roller 14. A controller 4 is installed at the top of one side of the main body 1 of the cutting device.
[0032] A top frame 6 is provided at one end of the top of the main body 1 of the cutting device, and a lead screw 15 is provided on one side inside the top frame 6. A drive block 16 is sleeved on the lead screw 15, and one side of the drive block 16 is connected to the tool holder 8 through a connecting rod 11. A second drive motor 7 is fixed at one end of the top of the top frame 6, and the output end of the second drive motor 7 is connected to the lead screw 15.
[0033] The second drive motor 7 starts, drives the lead screw 15 to rotate, and drives the drive block 16 to move along the lead screw 15. Through the connecting rod 11, it pushes the blade holder 8 close to the wire body 2, and adjusts the position of the cutting blade 9 so that it is above the wire body 2 and in contact with the wire sheath.
[0034] A guide rod 17 is provided on the side of the top frame 6 away from the lead screw 15. The side of the connecting rod 11 close to the guide rod 17 is slidably sleeved with the guide rod 17 through a guide sleeve to guide and limit the connecting rod 11.
[0035] Limiting blocks 12 are provided on both sides of the blade holder 8, and limiting grooves matching the limiting blocks 12 are provided on both sides inside the main body 1 of the cutting device to limit the vertical displacement of the blade holder 8, ensuring that the cutting blade 9 only moves vertically and avoids deviation in cutting depth due to movement.
[0036] When the wire feeding wheel 10 rotates, the wire body 2 moves forward and cuts the wire sheath through the cutting blade 9. When the cutting blade 9 contacts the wire sheath, the pressure sensors 13 at both ends of the roller 14 detect the contact pressure in real time and transmit the signal to the controller 4. If the pressure is less than the preset threshold, the controller 4 instructs the second drive motor 7 to rotate forward, and the lead screw 15 pushes the drive block 16 to move further, increasing the cutting depth of the cutting blade 9.
[0037] If the pressure is greater than the preset threshold, the controller 4 instructs the motor to reverse and the drive block 16 to retract, reducing the cutting depth. If the wire sheath thickness fluctuates, the pressure sensor 13 provides real-time feedback, and the controller 4 synchronously adjusts the rotation of the second drive motor 7 to ensure consistent cutting depth.
[0038] By using pressure feedback, it avoids "not cutting through" or "damaging the core wire". It is suitable for wire sheaths of different thicknesses. It can cope with working conditions such as uneven sheath thickness and changes in conveying speed, improve cutting consistency, and requires no manual intervention, reducing debugging time.
[0039] The specific models and specifications of the first drive motor 3, the second drive motor 7, the pressure sensor 13, and the controller 4 need to be determined based on the specifications and parameters of the device. The selection and calculation method is existing technology, so it will not be described in detail here.
[0040] Working Principle: In this embodiment, the first drive motor 3 starts and drives the wire feeding wheel 10 to rotate via the shaft, feeding the wire body 2 at a constant speed from the bottom of the cutting device body 1. Limiting frames 5 are set on both sides of the cutting device body 1, clamping the wire body 2 tightly with internal clamping wheels 18. The clamping wheels 18 on both sides form a centered clamping, ensuring that the wire body 2 passes through the cutting position along the axial centerline, avoiding deviation in the cutting position due to the wire body 2 shifting. The clamping wheels 18 inside the limiting frame 5 adaptively clamp wires of different diameters through buffer springs 22 and damping pads 21, buffering conveying vibrations and stabilizing the cutting position. When the conveying speed of the wire body 2 fluctuates or the wire diameter changes, the buffer springs 22 absorb the vibration of the bracket 19, preventing the clamping wheels 18 from impacting and squeezing the wire body 2. The damping pads 21 absorb the rigid impact when the buffer springs 22 are compressed to their limit, reducing impact noise and preventing buffering vibrations. When spring 22 is overloaded and damaged, the second drive motor 7 starts, driving the lead screw 15 to rotate. This causes the drive block 16 to move along the lead screw 15, pushing the cutter holder 8 closer to the wire body 2 via the connecting rod 11. The position of the cutting blade 9 is adjusted so that it is above the wire body 2 and in contact with the wire sheath. When the wire feed wheel 10 rotates, the wire body 2 moves forward and cuts the wire sheath through the cutting blade 9. When the cutting blade 9 contacts the wire sheath, the pressure sensors 13 at both ends of the roller 14 detect the contact pressure in real time and transmit the signal to the controller 4. If the pressure is less than the preset threshold, the controller 4 instructs the second drive motor 7 to rotate forward, and the lead screw 15 pushes the drive block 16 to move further, increasing the cutting depth of the cutting blade 9. If the pressure is greater than the preset threshold, the controller 4 instructs the motor to rotate in reverse, and the drive block 16 to retract, reducing the cutting depth. If the wire sheath thickness fluctuates, the pressure sensor 13 provides real-time feedback, and the controller 4 synchronously adjusts the rotation of the second drive motor 7 to ensure a consistent cutting depth.
