Description

Technical Field

[0001] This utility model relates to the field of enameled wire cutting technology, and in particular to an enameled wire cutting device. Background Technology

[0002] Enameled wire is a type of conductor coated with insulating varnish, widely used in motors, electrical appliances, power transformers, and other fields. Enameled wire mainly consists of two parts: a conductor and an insulating layer. The conductor is usually copper or aluminum, due to their excellent conductivity. Enameled wire is formed by coating the surface of copper or aluminum wire with insulating varnish. The insulating varnish coating provides insulation, preventing current leakage and protecting the conductor from external environmental influences.

[0003] In response, Chinese patent application number CN202122544111.7 discloses an enameled wire cutting device, including a processing table and an electric lifting sleeve rod.

A drive motor is fixedly installed inside the outer frame, and the output shaft of the drive motor is fixedly connected to a rotating shaft through a coupling. A connecting rod is fixedly installed at the bottom end of the rotating shaft.

[0004] However, existing enameled wire cutting devices typically use shearing blades to cut vertically, but this process usually only uses one set of shearing blades. Long-term, high-frequency use can cause the blades of the shearing blades to become worn and damaged, requiring replacement of the shearing blades, which reduces cutting efficiency and the practicality of the device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an enameled wire cutting device.

[0006] The purpose of this utility model is achieved as follows: A wire cutting device includes a worktable and a support column. A cutting mechanism and a tensioning mechanism are provided on the worktable. The cutting mechanism includes a fixed plate fixedly connected to the upper end of the worktable. A wire feeding roller is installed on the side wall of the fixed plate. The output shaft of the wire feeding roller is fixedly connected to the wire feeding roller via a coupling. A bracket is fixedly connected to the upper end of the worktable. A PLC controller is installed on the side wall of the bracket. A first cylinder is fixedly connected to the inner wall of the bracket. An adjusting plate is fixedly connected to the bottom output end of the first cylinder. A connecting plate is fixedly connected to the bottom end of the adjusting plate. A second servo motor is installed on the side wall of the connecting plate. A rotating roller is fixedly connected to the output shaft of the second servo motor via a coupling. A connecting seat is fixedly connected to the outer wall of the rotating roller. A cutting blade is installed inside the connecting seat. Four sets of connecting seats and cutting blades are symmetrically arranged along the circumference of the rotating roller. A cutting seat is fixedly connected to the upper end of the worktable.

[0007] Preferably, the shearing blade is equipped with mounting bolts, and the mounting bolts are installed inside the connecting seat.

[0008] Preferably, the shearing seat has a groove inside that corresponds to the shearing blade.

[0009] Preferably, the PLC controller is electrically connected to the first servo motor, the first cylinder, and the second servo motor.

[0010] Preferably, the tensioning mechanism includes a movable plate, which is disposed above the workbench. A U-shaped frame is fixedly connected to the upper end of the movable plate, and a second cylinder is fixedly connected to the inner wall of the U-shaped frame. A fixed seat is fixedly connected to the bottom output end of the second cylinder, and the fixed seat is fixedly connected to the side wall of the pressure plate. The pressure plate is placed above the movable plate.

[0011] Preferably, a fixed slide rail is fixedly connected to the upper end of the worktable, a slide groove is opened inside the fixed slide rail, a third cylinder is provided on the inner wall of the slide groove, a connecting block is fixedly connected to the output end of the third cylinder, and the connecting block is fixedly installed on the side walls of both ends of the moving plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes a fixed plate, a first servo motor, a feeding roller, a bracket, a PLC controller, a first cylinder, an adjusting plate, a connecting plate, a second servo motor, a rotating roller, a connecting seat, a shearing blade, and a shearing seat to feed enameled wire through the first servo motor and the feeding roller. The wire passes between the shearing seat and the shearing blade. Simultaneously, the PLC controller activates the first cylinder to move the adjusting plate downwards, which in turn moves the connecting plate downwards synchronously. This causes the rotating roller and its mounted shearing blade to move downwards in sync, facilitating convenient cutting of the enameled wire. The PLC controller provides coded control; after each cut, as the rotating roller moves upwards, the PLC controller activates the second servo motor, causing the rotating roller to rotate a quarter of a circle. This allows for changing the shearing blade used for the next cut, enabling convenient adjustment of different shearing blades for efficient cutting. This avoids the problem of a single shearing blade becoming worn and damaged due to prolonged use. Using four sets of shearing blades significantly extends the blade's lifespan, improving the device's practicality and efficiency.

[0014] 2. This utility model uses a moving plate, a U-shaped frame, a second cylinder, a fixed base, and a pressure plate to control a PLC controller. Activating the second cylinder causes the fixed base to move downwards, which in turn moves the pressure plate synchronously. The pressure plate and the moving plate work together to press the enameled wire, fixing this part of the wire in place. This tensioning effect makes cutting easier. The enameled wire cutting device can press the wire during the cutting process, ensuring tension and making cutting more convenient, thus improving the device's practicality and convenience.

Detailed Implementation

[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. 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.

[0022] like Figure 1-4 The present invention provides one embodiment as shown:

[0023] A wire cutting device is provided in this application. The workbench 111, support column 112, first servo motor 212, PLC controller 215, second servo motor 219, second cylinder 313 and third cylinder 318 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art.

[0024] The system includes a workbench 111 and a support column 112. The workbench 111 is equipped with a shearing mechanism 2 and a tensioning mechanism 3. The shearing mechanism 2 includes a fixed plate 211, which is fixedly connected to the upper end of the workbench 111. A wire feeding roller 213 is mounted on the side wall of the fixed plate 211, and the output shaft of the wire feeding roller 213 is fixedly connected to the wire feeding roller 213 via a coupling. A bracket 214 is fixedly connected to the upper end of the workbench 111. A PLC controller 215 is mounted on the side wall of the bracket 214, and a first cylinder 216 is fixedly connected to the inner wall of the bracket 214. An adjusting plate 217 is fixedly connected to the bottom output end of cylinder 216. A connecting plate 218 is fixedly connected to the bottom end of adjusting plate 217. A second servo motor 219 is installed on the side wall of connecting plate 218. A rotating roller 220 is fixedly connected to the output shaft of the second servo motor 219 through a coupling. A connecting seat 221 is fixedly connected to the outer wall of rotating roller 220. A shearing blade 222 is installed inside the connecting seat 221. Four sets of connecting seats 221 and shearing blades 222 are symmetrically arranged along the circumference of rotating roller 220. A shearing seat 223 is fixedly connected to the upper end of worktable 111.

[0025] When using this enameled wire cutting device, the enameled wire is fed out by the first servo motor 212 in conjunction with the feeding roller 213, allowing the wire to pass between the cutting seat 223 and the cutting blade 222. The PLC controller 215 is controlled in real time to activate the first cylinder 216, which drives the adjusting plate 217 downwards, thereby causing the connecting plate 218 to move downwards synchronously. This causes the rotating roller 220 and its mounted cutting blade 222 to move downwards synchronously, facilitating convenient cutting of the enameled wire. Using the PLC controller 215 for coded control, during the upward movement of the rotating roller 220 after each cut, the PLC controller 215 activates the second servo motor 219, causing the rotating roller 220 to rotate a quarter circle. This allows for changing the cutting method for the next set of cuts, using a different cutting blade 222 to avoid the problem of a single cutting blade 222 becoming worn and easily damaged due to prolonged cutting. Using four sets of cutting blades 222 in conjunction significantly extends the service life of the cutting blades 222.

[0026] The shearing blade 222 has a mounting bolt 224 installed inside, and the mounting bolt 224 is installed inside the connecting seat 221;

[0027] The shearing blade 222 is assembled inside the connecting seat 221 by mounting bolts 224, which allows for easy disassembly and replacement of the damaged shearing blade 222.

[0028] The shearing seat 223 has a groove inside corresponding to the shearing blade 222;

[0029] By creating a groove inside the shearing seat 223 corresponding to the shearing blade 222, the cutting is carried out in the groove inside the shearing seat 223, resulting in a better cutting effect.

[0030] The PLC controller 215 is electrically connected to the first servo motor 212, the first cylinder 216, and the second servo motor 219.

[0031] The tensioning mechanism 3 includes a movable plate 311, which is positioned above the workbench 111. A U-shaped frame 312 is fixedly connected to the upper end of the movable plate 311. A second cylinder 313 is fixedly connected to the inner wall of the U-shaped frame 312. A fixed seat 314 is fixedly connected to the bottom output end of the second cylinder 313. The fixed seat 314 is fixedly connected to the side wall of the pressure plate 315, which is positioned above the movable plate 311.

[0032] When using this enameled wire cutting device, the PLC controller 215 is controlled to start the second cylinder 313, which drives the fixed seat 314 to move downward, thereby driving the pressure plate 315 to move synchronously. The pressure plate 315 and the moving plate 311 work together to press the enameled wire, fixing this part of the wire in place. This can tension the enameled wire, making it easier to cut.

[0033] A fixed slide rail 316 is fixedly connected to the upper end of the workbench 111. A slide groove 317 is opened inside the fixed slide rail 316. A third cylinder 318 is provided on the inner wall of the slide groove 317. A connecting block 319 is fixedly connected to the output end of the third cylinder 318. The connecting block 319 is fixedly installed on the side walls of both ends of the moving plate 311.

[0034] After the first cut is completed, the PLC controller 215 can be controlled to start the third cylinder 318, which drives the connecting block 319 to move, thereby driving the moving plate 311 and the tensioning mechanism 3 on it to move synchronously towards the shearing mechanism 2. The second cylinder 313 returns to its original position, and the wire feeding roller 213 continues to feed the wire. This process does not require manual pulling of the wire feeding, making the cutting more convenient.

[0035] Working principle:

[0036] When using this enameled wire cutting device, the enameled wire is fed out by the first servo motor 212 in conjunction with the feeding roller 213, allowing the wire to pass between the cutting seat 223 and the cutting blade 222. The PLC controller 215 is controlled in real time to activate the first cylinder 216, which drives the adjusting plate 217 downwards, thereby causing the connecting plate 218 to move downwards synchronously. This causes the rotating roller 220 and its mounted cutting blade 222 to move downwards synchronously, facilitating convenient cutting of the enameled wire. Using the PLC controller 215 for coded control, during the upward movement of the rotating roller 220 after each cut, the PLC controller 215 activates the second servo motor 219, causing the rotating roller 220 to rotate a quarter circle. This allows for changing the cutting method for the next set of cuts, using a different cutting blade 222 to avoid the problem of a single cutting blade 222 becoming worn and easily damaged due to prolonged cutting. Using four sets of cutting blades 222 in conjunction significantly extends the service life of the cutting blades 222.

[0037] When using this enameled wire cutting device, control the PLC controller 215 to start the second cylinder 313, which drives the fixed seat 314 to move downward, thereby driving the pressure plate 315 to move synchronously. The pressure plate 315 and the moving plate 311 work together to press the enameled wire, fixing this part of the wire in place. This can tension the enameled wire, making it easier to cut. The operation is then complete.

[0038] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
