Description

Technical Field

[0001] This utility model relates to the field of PEEK sheet cutting technology, and in particular to a cutting device for PEEK sheet processing. Background Technology

[0002] PEEK sheet is a high-performance special engineering plastic with excellent heat resistance, chemical corrosion resistance, mechanical strength and electrical insulation. It is widely used in high-end fields such as aerospace, medical devices, electronic information, and automobile manufacturing. In the actual application of PEEK sheet, it is often necessary to cut it into sheets of different sizes and shapes according to specific usage requirements.

[0003] PEEK board processing cutting equipment is a professional device used for cutting PEEK boards. It covers a variety of types, from basic cutting tools to high-precision automated devices. The core function of PEEK board cutting equipment is to achieve precise cutting of boards through mechanical or laser cutting technology. When cutting PEEK boards of different thicknesses, it is necessary to change the blades. At the same time, due to the high hardness and wear resistance of PEEK boards, the blades of existing cutting equipment wear out quickly and require frequent blade replacement.

[0004] However, the existing cutting device has a complicated tool changing process, resulting in excessive downtime and reduced overall processing efficiency, making it difficult for the existing cutting device to meet the requirements of high-efficiency processing of PEEK boards.

[0005] Therefore, given the complex tool replacement process of the existing cutting device, which leads to excessive downtime, a new cutting device for PEEK board processing can be designed to quickly replace the tools and reduce equipment downtime. Utility Model Content

A transmission rod is fixedly connected to the inner cavity of each bushing via bolts. Several blades are fixedly sleeved on the surface of the transmission rod. Teeth are provided in the inner cavity of the front end of the annular frame, and the teeth mesh with a first gear.

[0009] Preferably, when slitting the PEEK board, rotating the first gear drives the ring frame to rotate, which in turn drives the matching transmission rod and blade to rotate to the bottom via the bushing. Then, the transmission rod is driven to rotate the bushing and blade, thereby realizing the slitting process of the PEEK board.

[0010] When it is necessary to change the tool, stop the rotation of the transmission rod, drive the first gear to move the ring frame to the bottom of the spare blade area, and perform the same operation to continue cutting the PEEK board. At the same time, remove the bolt from the removed bushing surface, pull out the transmission rod and the blade for replacement. The whole process is convenient to operate, effectively shortens the tool change and downtime time, and improves the continuous processing capability of the equipment.

[0011] Preferably, the cutting mechanism further includes a third cylinder, which is fixed on both sides of the first frame. The telescopic end of the third cylinder passes through the inner cavity of the first frame and is fixedly connected to a fixing block. A fourth cylinder is fixedly connected to the top of the fixing block. The telescopic end of the fourth cylinder passes through the fixing block and is fixedly connected to a milling cutter assembly.

[0012] Preferably, the top of the first frame is provided with a first sliding groove, and a second slider is fixedly connected to one side of each of the fixed blocks. The second slider extends into the inner cavity of the first sliding groove and is slidably connected thereto.

The output shaft of the second motor is movably inserted into the inner cavity of the transmission rod and is connected to it for transmission.

[0015] Preferably, the moving mechanism includes a moving frame, a third sliding groove is provided on one side of the moving frame, and first sliders are fixed on both sides of the second frame.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] Please see Figures 1-9 This utility model provides a cutting device for processing PEEK board, including a first frame 1, on which a cutting mechanism 2 is provided;

[0034] The cutting mechanism 2 includes an annular frame 205 disposed on one side of the first frame 1. Two bushings 206 are fixedly connected to one side of the annular frame 205 by bearings. The inner cavity of each bushing 206 is fixedly connected to a transmission rod 207 by bolts. Several blades 208 are fixedly sleeved on the surface of the transmission rod 207. The inner cavity of the front annular frame 205 is provided with teeth 209, which mesh with a first gear 210.

[0035] The four corners of the inner cavity of the first frame 1 are fixedly connected with the second cylinder 10. The telescopic end of the second cylinder 10 passes through the first frame 1 and is fixedly connected with the limiting block 11. Between the two limiting blocks 11, the roller 12 is fixed by bearing.

[0036] A second frame 3 is provided at the bottom of the first frame 1, and a moving mechanism 4 is provided at the top of the second frame 3. A first motor 5 is fixed on one side of the first frame 1. The output shaft of the first motor 5 passes through the inner cavity of the first frame 1 and is connected to the first gear 210 for transmission. A first cylinder 6 is fixed on one side of the first frame 1. The telescopic end of the first cylinder 6 passes through the inner cavity of the first frame 1 and is fixedly connected to the second motor 7. The output shaft of the second motor 7 is movably inserted into the inner cavity of the transmission rod 207 and is connected to it for transmission.

[0037] The bottom of the second frame 3 is provided with a rack 14, and the bottom of the movable frame 401 is provided with a placement groove 403. The inner cavity of the placement groove 403 is fixedly connected to a drive shaft 404 through a bearing. Both ends of the drive shaft 404 are fixedly sleeved with second gears 405, and the rack 14 meshes with the second gears 405.

[0038] During operation, when cutting PEEK sheets, the first motor 5 is started. The output shaft of the first motor 5 drives the first gear 210 to rotate, which in turn drives the ring frame 205 to rotate. Through the bushing 206, the matching transmission rod 207 and the blade 208 rotate to the bottom, placing the PEEK sheet to be cut on the surface of the moving frame 401. The transmission shaft 404 in the placement groove 403 at the bottom of the moving frame 401 rotates under the meshing action of the rack 14 and the second gear 405, smoothly cutting the PEEK sheet. The PEEK board is conveyed to the cutting area to ensure precise slitting. Simultaneously, the second cylinder 10 adjusts its extension and retraction according to the thickness of the PEEK board, pushing the limit block 11 to firmly clamp the board and prevent displacement during slitting. The extension and retraction end of the first cylinder 6 drives the second motor 7, causing its output shaft to rotate within the transmission rod 207. Starting the second motor 7, the transmission rod 207 drives the bushing 206 and the blade 208 to rotate, achieving efficient and stable slitting of the PEEK board.

[0039] When a tool replacement is needed, the first cylinder 6 is retracted, causing the output end of the second motor 7 to separate from the transmission rod 207. Simultaneously, the second cylinder 10 retracts, driving the limit block 11 and roller 12 to rise, activating the first motor 5. The output shaft of the first motor 5 drives the first gear 210 to rotate, thereby moving the spare blade 208 to the bottom via the ring frame 205. The first cylinder 6 then drives the second motor 7 to perform the same operation, continuing to cut the PEEK board. At the same time, the bolts are removed from the removed bushing 206, and the transmission rod 207 and blade 208 are pulled out for replacement. The entire process is convenient, effectively shortening the tool replacement and downtime time, and improving the continuous processing capability of the equipment.

[0040] Example 2

[0041] Please see Figure 4 The difference from Embodiment 1 is that the cutting mechanism 2 also includes a third cylinder 201. The third cylinder 201 is fixed on both sides of the first frame 1. The telescopic end of the third cylinder 201 passes through the inner cavity of the first frame 1 and is fixedly connected to the fixing block 202. A fourth cylinder 203 is fixedly connected to the top of the fixing block 202. The telescopic end of the fourth cylinder 203 passes through the fixing block 202 and is fixedly connected to the milling cutter assembly 204.

[0042] When using the milling cutter assembly 204 to cut the PEEK board, both the transmission rod 207 and the blade 208 are rotated to the top. The third cylinder 201 on one side pushes the fixed block 202 to move, and the fourth cylinder 203 pushes the milling cutter assembly 204 to rise and fall, thereby cutting the PEEK board.

[0043] When the milling cutter needs to be replaced, the milling cutter assembly 204 is stopped, and the third cylinder 201 and the fourth cylinder 203 retract simultaneously. The third cylinder 201 on the other side drives the milling cutter assembly 204 into the cutting position to continue the cutting operation. Thus, the stopped milling cutter assembly 204 can be replaced and kept on standby without stopping the machine. The milling cutter assembly 204 includes a motor, coupling, transmission mechanism and milling cutter, and power is transmitted through mechanical connection. It is different from the cutting method of the blade 208 and can be used as another way of cutting sheet metal.

[0044] Example 3

[0045] Please see Figure 5 The difference from Embodiment 1 is that the top of the first frame 1 is provided with a first slide groove 8, and a second slider 211 is fixedly connected to one side of the fixing block 202. The second slider 211 extends into the inner cavity of the first slide groove 8 and is slidably connected thereto. The inner cavity of the first frame 1 is provided with a second slide groove 9, and the ring frame 205 extends into the inner cavity of the second slide groove 9 and is slidably connected thereto.

[0046] With the sliding cooperation of the first slide groove 8 and the second slider 211, the movement trajectory of the fixed block 202 can be precisely guided, avoiding deviation during the pushing process and ensuring the accuracy of the PEEK board conveying position. At the same time, the second slide groove 9 provides a stable space for the sliding of the ring frame 205, making the ring frame 205 more stable when driving the blade 208 to move, reducing the deviation of the tool replacement caused by shaking, and further improving the stability and reliability of the device in continuous operation and complex cutting processes.

[0047] Example 4

[0048] Please see Figures 7-8 The difference from Embodiment 1 is that the moving mechanism 4 includes a moving frame 401, a third slide groove 402 is provided on one side of the moving frame 401, and a first slider 13 is fixed on both sides of the second frame 3. The first slider 13 extends into the inner cavity of the third slide groove 402 and is slidably connected to it.

[0049] Through the sliding engagement of the first slider 13 and the third slide groove 402, the moving frame 401 can move smoothly, thereby smoothly conveying the PEEK board to the cutting area and ensuring the accurate execution of the slitting work. This sliding connection method not only reduces the frictional resistance of the moving frame 401 during the movement process, reduces wear between components, and extends the service life of the device, but also effectively avoids the problem of scratches or positional displacement on the surface of the PEEK board caused by unstable conveying, laying a solid foundation for the high-precision execution of subsequent cutting processes.

[0050] Example 5

[0051] Please see Figures 7-8 The difference from Embodiment 2 is that a protective groove 15 is provided on the top of the second frame 3, and a third motor 406 is fixedly connected to the front end of the movable frame 401. The telescopic end of the third motor 406 passes through the inner cavity of the movable frame 401 and is connected to the drive shaft 404 for transmission.

[0052] Driven by the third motor 406, the second gear 405 rotates, causing the moving frame 401 to precisely shift at the top of the second frame 3. This smoothly transports the PEEK board to the cutting area, ensuring accurate slitting. Simultaneously, the protective groove 15 design prevents damage to the surface of the second frame 3 during PEEK board slitting. The compact connection between the telescopic end of the third motor 406 and the transmission shaft 404 provides a fast response and allows for flexible adjustment of the moving frame 401's displacement distance and speed according to the cutting requirements of different PEEK board specifications. This enhances the device's adaptability to diverse processing tasks, further ensuring the consistency and stability of cutting dimensions, and providing strong support for continuous, high-precision processing of large batches of PEEK boards.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
