Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a steel coil slitting and cutting device with integrated blade for deep machining. Background Technology

[0002] In the field of metal processing, especially in the sheet metal forming and finishing process, the slitting of steel coils is a key process. Its core purpose is to efficiently and accurately cut wide steel coils into multiple narrow strips of a specific width.

[0003] Traditional slitting equipment mainly relies on high-speed rotating CNC cutting tools (i.e., disc cutters) to continuously cut flat steel coils longitudinally. This process is usually completed on dedicated forming machine tools (such as slitting lines). However, in high-speed, high-load continuous metal cutting operations, the cutting edge of the CNC cutting tool will inevitably wear, increase in temperature, and adhere to cutting chips and oil, resulting in decreased sharpness, increased cutting force, increased product burrs, and even blade chipping.

[0004] To solve this problem, traditional methods often require frequent machine shutdowns to disassemble the blades for offline grinding and cleaning. This not only severely restricts the continuous operation efficiency of the forming machine and increases manual maintenance costs, but also the repeated installation of the blades can easily introduce precision errors, affecting the stability of the slitting quality.

[0005] Therefore, how to achieve real-time, online maintenance and performance recovery of CNC cutting tools on the production line, that is, to perform deep machining of the cutting tools so that they can maintain optimal working condition during cutting operations, has become a key technical challenge to improve the slitting process, ensure product quality and reduce overall costs.

The other end of each of the two protective side plates is equipped with a dust removal mechanism for cleaning the surface of the disc cutter.

[0013] Preferably, the drive mechanism includes two motors fixed to opposite sides of two support frames. One end of the motor passes through the front of the support frame and is fixed with a drive gear. Both ends of the rotating rod are fixed with transmission gears. The drive gear and transmission gear at opposite ends are meshed with a transmission belt.

[0014] Preferably, the drive mechanism two includes two motors two fixed to the top of two support frames respectively, and the output ends of the two motors two are fixed to the threaded rods on the corresponding support frames respectively.

[0015] Preferably, the grinding plate mechanism includes two guide rails symmetrically arranged on the outer side of one end of the protective side plate, and a connecting groove opened between the two guide rails.

[0016] The sides of the two guide rails are fitted with movable plates, and positioning bolts are threaded onto the movable plates, with one end of the positioning bolts fitting against the guide rails.

[0017] Preferably, the shaft of the movable plate is rotatably connected to a sleeve, one end of which is slidably connected in a connecting groove. A telescopic rod is movably sleeved inside the sleeve, and a grinding wheel is fixed at one end of the telescopic rod, which is in contact with the side of the disc cutter.

[0018] Preferably, a limiting groove is provided on the side of the sleeve along its length, and a limiting button is fixed on the side of the telescopic rod. The limiting button is slidably connected in the limiting groove, and a tension spring is fixed between the limiting button and one end in the limiting groove.

[0019] Preferably, the transmission mechanism includes a speed-changing component and a transmission component. The speed-changing component includes a fitting opening at the center of the bottom of the protective side plate, a transmission groove on one side inside the fitting opening, a gear one rotatably connected inside the transmission groove, a gear two meshing on the side of the gear one, a gear three fixed on the back of the gear two, and a gear four meshing on the side of the gear three.

[0020] Preferably, the transmission component includes a telescopic sleeve rod and two connecting rods. One end of the inner and outer rods of the telescopic sleeve rod is fixed with a connector. Both ends of the two connecting rods are rotatably connected with ball bearings. The ball bearings at one end of the two connecting rods are rotatably connected to the corresponding connectors. The ball bearings at the other end of the two connecting rods are respectively rotatably connected to transmission rod one and transmission rod two.

[0021] Preferably, the dust removal mechanism includes two connecting blocks symmetrically arranged on the inner side of one end of the protective side plate, with a mounting plate rotatably connected between the two connecting blocks, and a cleaning panel fixed on the mounting plate, the cleaning panel being attached to the side of the disc cutter.

[0022] Preferably, the dust removal mechanism also includes a mounting groove at one end of the protective side plate, in which a hydraulic rod is rotatably connected, and the output end of the hydraulic rod is fixed to the back of the mounting plate.

[0023] Compared with the prior art, the present invention provides a steel coil slitting and cutting device with integrated blade deep processing, which has the following beneficial effects: 1. This integrated blade deep processing steel coil slitting device integrates blade maintenance functions onto the slitting forming machine tool and directly utilizes the cutting kinetic energy of the CNC blade rotation to drive the grinding plate mechanism and dust removal mechanism. While the metal cutting and slitting operation is in progress, constant pressure fine grinding and surface cleaning of the CNC blade side can be completed simultaneously. This achieves true online cutting blade deep processing, avoiding the drawbacks of traditional methods that require stopping the machine to disassemble the blade, and greatly improving the overall operating efficiency and production capacity of the equipment.

[0024] 2. This integrated blade deep-processing steel coil slitting device, through the synergistic action of the grinding plate mechanism and the dust removal mechanism, can continuously remove micro-wear, deposits, and heat-affected zones from the blade edge during the production process, keeping the blade sharp for a long time. The constant pressure adaptive grinding mechanism ensures the uniformity and stability of the grinding effect, which not only significantly extends the service life of expensive CNC blades and reduces consumable costs, but more importantly, ensures the smoothness and dimensional accuracy of the slitting surface, significantly improving the forming quality of the final product.

[0025] 3. This integrated blade deep-processing steel coil slitting device features adjustable blade spacing and flexible adjustment and locking of the height and horizontal position of the maintenance components. It can quickly adapt to the processing requirements of steel coils of different specifications. The adaptive spring pressure and compensating telescopic structure in the maintenance components can automatically adapt to the radial runout caused by blade wear or installation, maintaining a constant grinding contact pressure. This reflects the characteristics of intelligent maintenance, reduces the reliance on manual intervention and experience, and improves the automation effect of the entire forming machine tool. Furthermore, the position of the grinding wheel can be adjusted by the moving plate, allowing it to flexibly adapt to disc cutters of different diameters.

[0026] 4. This integrated blade deep-processing steel coil slitting device features a compact structure that highly integrates drive and maintenance functions, without occupying additional production line space. Utilizing spindle power for self-driven maintenance eliminates the need for a separate external power source, resulting in energy efficiency and high performance. It provides a highly efficient and innovative solution for the development of traditional metal cutting and forming machine tools towards high integration, self-maintenance, and high performance.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1 Please see Figure 1 - Figure 9 As shown in the figure, the steel coil slitting device with integrated blade deep processing proposed in this embodiment includes a horizontally arranged material conveying machine 1 for conveying steel coils and serving as the installation platform for the entire device. At each end of the material conveying machine 1 along its length direction (horizontal conveying direction), a stabilizing side plate 11 is fixed for installing subsequent functional components (the drive component 2, cutting component 3 and maintenance component 4 described below) to enhance the overall rigidity.

[0031] The material conveying machine tool 1 is equipped with a drive assembly 2, which includes two U-shaped tilting support frames 21. The horizontal walls below the two support frames 21 are fixed to the top of the stabilizing side plates 11 at both ends of the machine tool by bolts. After fixing, the two support frames 21 are in a relative state. Two sets of drive mechanisms are installed between the support frames 21: drive mechanism 1 22, which is responsible for providing cutting power when the steel coil is cut, and drive mechanism 2 23, which is responsible for adjusting the height position of the functional component (here referring to the maintenance component 4).

[0032] The drive mechanism 22 includes a horizontally arranged rotating rod 221, whose two ends are rotatably connected between the vertical walls of two support frames 21 via bearing seats, and located near the top. To achieve the rotation of the rotating rod 221, a motor 222 is fixed on the opposite side of the vertical walls of the two support frames 21, near the bottom. The two motors 222 operate synchronously through the system settings. The output end of each motor 222 extends horizontally through the front of the support frame 21 (i.e., the opposite side of the two support frames 21), and a drive gear 223 is fixed at its front end. At the same time, a transmission gear 224 is fixed at each end of the rotating rod 221. The drive gear 223 and the transmission gear 224 at the corresponding ends mesh with the same transmission belt 225. When the two motors 222 operate synchronously, the output end drives the drive gear 223 to rotate, and under the transmission of the transmission belt 225, the transmission gear 224 drives the rotating rod 221 to rotate at high speed.

[0033] The drive mechanism 23 includes two vertically arranged threaded rods 231 and a horizontally arranged lifting rod 232. The threads on the sides of the two threaded rods 231 are opposite, and their bottom ends are rotatably connected to the top surface of the horizontal wall above the corresponding support frame 21 via bearings. Both ends of the lifting rod 232 are provided with threaded holes with opposite threads. The two threaded rods 231 are threaded into the corresponding threaded holes. When the two threaded rods 231 rotate synchronously in opposite directions, the lifting rod 232 moves up and down by meshing with the threads in the threaded holes. To drive the two threaded rods 231 to rotate synchronously, a motor 233 is fixed on the bottom surface of the horizontal wall above each of the two support frames 21. The two motors 233 operate synchronously through the system settings. The output end of the motor 233 extends upward through the top surface of the horizontal wall and is fixed to the bottom end of the threaded rod 231. When the two motors 233 operate synchronously, the output end drives the threaded rod 231 to rotate, ultimately realizing the lifting motion of the lifting rod 232.

[0034] The drive mechanism 22 is equipped with a cutting assembly 3 for longitudinally slitting steel coils. This assembly includes multiple disc cutters 31 that serve as core CNC blades to perform metal cutting tasks. The spacing of the disc cutters 31 can be determined according to the slitting width requirements. They are sequentially fitted onto the rotating rod 221. To fix the axial position of each disc cutter 31 on the rotating rod 221, positioning rings 32 are provided on both sides of the blade shaft. Screws are threaded onto the sides of the positioning rings 32. At the same time, multiple positioning holes are evenly distributed along the length of the rotating rod 221. By screwing the screws into the corresponding positioning holes, the current position of the disc cutter 31 is fixed, meeting the depth processing requirements of steel coils of different specifications. When the rotating rod 221 rotates, it can drive the disc cutters 31 to rotate simultaneously, realizing the longitudinal slitting operation of the steel coils laid flat below.

[0035] The drive mechanism 23 is equipped with a maintenance component 4 to ensure the stability and long-lasting sharpness of the cutting blade (i.e., the disc cutter 31) during deep machining. This component includes two protective side plates 41 symmetrically arranged on the side of each disc cutter 31. Each protective side plate 41 is horizontally arranged in a [shape], and a connecting frame 411 is fixed on its top. The top of the connecting frame 411 is annular. The same sleeve 412 is installed between the connecting frames 411 on the two protective side plates 41 of each blade (disc cutter 31). The outer side of the sleeve 412 has opposite threads from the middle to both ends. By rotating the sleeve 412 in the forward direction, the two ends of the sleeve engage with the internal threads of the annular ring, so that the two protective side plates 41 move in opposite directions to a closed state (i.e., move closer to the disc cutter 31). By rotating the sleeve 412 in the reverse direction, the two protective side plates 41 move in opposite directions to a separated state (i.e., move away from the disc cutter 31).

[0036] The inner diameter of the sleeve 412 matches the diameter of the lifting rod 232 and is fitted onto its side. A screw is threaded into the middle of the outer side of the sleeve 412, with one end of the screw tightened onto the side of the lifting rod 232 to fix the current position of the maintenance component 4. This allows the lifting rod 232 to drive the sleeve 412 and the entire maintenance component 4 to move up and down, enabling it to assemble or separate from the disc cutter 31. When assembled, the protective side plates 41 on both sides descend to the sides of the blade. While the blade is rotating at high speed and cutting, the maintenance component 4 maintains the blade for maintenance.

[0037] Each protective edge plate 41 has a grinding plate mechanism 42 for sharpening the blade and a transmission mechanism 43 for providing power to it installed at one end of its outer side, and a dust removal mechanism 44 for cleaning the blade surface installed at the other end.

[0038] The grinding plate mechanism 42 includes two guide rails 421 installed parallel to each other along the length of the outer side of the protective side plate 41. A strip-shaped connecting groove 422 is provided between the two guide rails 421 to connect the inner side of the protective side plate 41 (i.e., the direction close to the disc cutter 31). A vertical moving plate 423 is slidably connected to the side of the two guide rails 421. A positioning bolt 4231 is threaded on the moving plate 423. When tightened, its end can press against the surface of the guide rail 421, thereby locking the moving plate 423 in any desired position and realizing the lateral adjustment of the grinding position.

[0039] A sleeve 424 is rotatably connected to the center of the movable plate 423 via a bearing. One end of the sleeve 424 extends into and is slidably connected in the connecting groove 422, so that when the movable plate 423 slides on the guide rail 421 for adjustment, the sleeve 424 slides in the connecting groove 422. When the sleeve 424 moves to the limit of either end of the connecting groove 422, it restricts the movable plate 423 from disengaging from the guide rail 421.

[0040] A telescopic rod 425 is movably sleeved inside one end of the sleeve 424, which extends into the connecting groove 422. The front end of the telescopic rod 425 is fixed with a grinding wheel 426 facing the disc cutter 31. Thus, when the moving plate 423 adjusts it to any position, the grinding wheel 426 can still fit against the side of the rotating disc cutter 31, maintaining alignment and uniform grinding.

[0041] The dust removal mechanism 44 includes two connecting blocks 441 that are symmetrically fixed to the top and bottom of the inner side of one end of the protective side plate 41. A rectangular mounting plate 442 is rotatably connected between the two connecting blocks 441. A cleaning panel 4421 (such as felt or non-woven fabric) is glued to the mounting plate 442. The cleaning panel 4421 is attached to the other side of the disc cutter 31 under the action of external force, and is used to scrape off or absorb oil and debris generated during cutting.

[0042] Furthermore, a mounting groove 443 is provided on the protective side plate 41, and a hydraulic rod 444 is movably connected in the mounting groove 443. The upper and lower sides of the hydraulic rod 444 are connected to the corresponding wall surfaces in the mounting groove 443 through bearings. At the same time, the output end of the hydraulic rod 444 is fixed to the shaft position on the back of the mounting plate 442. By operating the hydraulic rod 444, its output end extends and retracts, thereby pushing and pulling the mounting plate 442, causing the mounting plate 442 to rotate around the connecting block 441 as the shaft. At the same time, the hydraulic rod 444 rotates in the mounting groove 443 through the bearings, thereby controlling the cleaning panel 4421 to effectively adhere to the surface of a disc blade 31 and adjusting the adhesion pressure.

[0043] The working principle of the steel coil slitting device with integrated blade deep processing proposed in this embodiment is as follows: Before use, the spacing between the disc blades 31 and the rotating rod 221 is pre-adjusted according to the required slitting width, and fixed by the positioning ring 32 cooperating with the positioning hole. Then, the drive mechanism 23 is controlled to drive the two threaded rods 231 to rotate synchronously at the output ends of the two motors 233. Through the threaded engagement of the threaded rods 231 with the threads at both ends of the lifting rod 232, the lifting rod 232 drives the maintenance component 4 on it to move down as a whole. At this time, by adjusting the position of the protective side plate 41 on both sides of the disc blades 31, and then sliding the moving plate 423 to drive the grinding wheel 426 along the disc blades 31, the device can be used to achieve the desired slitting width. Align the side of the blade 31 with the desired grinding position, then tighten the positioning bolt 4231 to fix the moving plate 423 in the current position. At the same time, the hydraulic rod 444 of the dust removal mechanism 44 can be activated to push the mounting plate 442 to rotate, so that the cleaning panel 4421 is pressed against the other side of the disc blade 31 with appropriate pressure. After adjustment, by rotating the screws on it, fix the sleeve 412 installed at the top of the protective side plate 41 to the current position of the lifting rod 232. Finally, control the output ends of the two motors 233 to operate in reverse, so that the lifting rod 232 drives the maintenance component 4 to move upward and detach from the disc blade 31, thus completing the assembly and adjustment work of the device in the early stage of operation.

[0044] In use, the steel coil to be processed is laid flat on the conveying machine tool 1 and conveyed along its length. The two motors 222 of the drive mechanism 22 are started and made to run synchronously. The motor 222 drives the rotating rod 221 to rotate through the drive gear 223, the transmission belt 225 and the transmission gear 224, thereby driving all the disc cutters 31 to rotate synchronously and longitudinally cut the steel coil passing below.

[0045] While the slitting operation continues, the side of the rotating disc cutter 31 generates relative friction with the fixed grinding wheel 426, achieving preliminary online grinding. The oil and debris on the other side are scraped or absorbed by the cleaning panel 4421, thus achieving basic maintenance and cleaning of the cutting blade without interrupting production, ensuring the stability of the slitting process and the service life of the blade.

[0046] Example 2 Please see Figure 3 - Figure 9 As shown in this embodiment, the steel coil slitting device for integrated blade deep processing, based on Embodiment 1, further includes, in order to enable the grinding wheel 426 to adaptively and tightly fit the side of the disc cutter 31 and provide constant pressure to the disc cutter 31, a limiting groove 4241 is provided axially on the sleeve wall 424. At the same time, a limiting button 4251 matching the width of the groove is fixed on the telescopic rod 425. The button is slidably connected in the groove, and a tension spring 4252 is fixed between the end of the groove away from the grinding wheel 426 and the button. Under the elastic force of the spring, the telescopic rod 425 is pushed outward (i.e., towards the disc cutter 31), causing the grinding wheel 426 to press against the side of the disc cutter 31. When the disc cutter 31 experiences slight radial runout due to wear or installation error, the telescopic rod 425 can perform compensatory extension and retraction to ensure relatively stable grinding force and realize online fine grinding and deep dressing of CNC blades.

[0047] The transmission mechanism 43 is used to transmit the kinetic energy of the rotating disc cutter 31 to the grinding plate mechanism 42, so that the grinding wheel 426 rotates at high speed. The mechanism includes a speed change component 431 and a transmission component 432.

[0048] The transmission component 431 is located inside one end of the protective side plate 41. It includes a fitting opening 4311 at the center of the bottom of the protective side plate 41. The fitting opening 4311 is used to accommodate the rotating positioning ring 32. The side of the positioning ring 32 is provided with a tooth profile. At the same time, a transmission groove 4312 is provided on one side of the fitting opening 4311 (i.e., towards the connecting groove 422). A gear 4313 is rotatably connected in the transmission groove 4312 through a rotating shaft. The teeth of the gear 4313 are exposed in the fitting opening 4311. When the protective side plate 41 is lowered to the working position, the gear 4313 can mesh with the tooth profile on the side of the positioning ring 32.

[0049] In the transmission groove 4312, gears 2 4314, 3 4315 and 4316 are rotatably connected by a rotating shaft. The multiple gears are arranged laterally. Gears 2 4314 and 3 4315 are coaxially fixed, while gear 1 4313 meshes with gear 2 4314, and gear 3 4315 meshes with gear 4316, forming a variable speed gear set. This realizes that the cutting power of the rotating disc cutter 31 is transformed into high-speed power output after speed change processing.

[0050] The transmission component 432 is used to transmit the high rotational power output by the transmission component 431 to the grinding wheel 426. It includes a telescopic sleeve rod 4321 arranged in the horizontal direction and two connecting rods 4322. The telescopic sleeve rod 4321 is composed of an inner rod and an outer rod. The inner cross-section of the outer rod is square, and the cross-sectional shape of the inner rod matches the inner shape of the outer rod, so that the outer rod can drive the inner rod to rotate at the same time.

[0051] Both rods (inner rod and outer rod) have connectors 4323 fixed at opposite ends. One end of each connector 4323 and both ends of each connecting rod 4322 have U-shaped interfaces. Each of the interfaces at both ends of the connecting rod 4322 has a ball bearing 4324 connected by a knob.

[0052] One of the connecting rods 4322 has a ball bearing 4324 at one end connected to the interface of the outer rod end connector 4323 via a knob, while the ball bearing 4324 at the other end of the connecting rod 4322 is connected to a transmission rod 4325 via a knob. One end of the transmission rod 4325 is fixed to the shaft of the gear 4316.

[0053] One of the connecting rods 4322 has a ball bearing 4324 at one end connected to the interface of the inner rod end connector 4323 via a knob. The ball bearing 4324 at the other end of the connecting rod 4322 is connected to a transmission rod 4326 via a knob. One end of the transmission rod 4326 is fixed to one end of the sleeve 424 (outer side of the protective side plate 41). When the disc cutter 31 drives the positioning ring 32 to rotate, the meshing force between the outer tooth profile of the ring and the gear 4313 is used. After speed change by the speed change component 431, the gear 4316 drives the transmission rod 4325 to rotate in the opposite direction. The kinetic energy is then transmitted to the transmission rod 4326 by the transmission component 432, causing the transmission rod 4326 to drive the sleeve 424 to rotate. Finally, the telescopic rod 425 drives the grinding wheel 426 to rotate. Under the cooperation of spring pressure, the disc cutter 31 is ground, completing the online adaptive cutting tool depth processing maintenance.

[0054] The working principle of the steel coil slitting device with integrated blade deep processing proposed in this embodiment is as follows: When the maintenance component 4 descends to the working position, the fitting opening 4311 under the protective side plates 41 on both sides fits onto the side of the positioning ring 32. At the same time, the positioning ring 32 meshes with gear 1 4313. At this time, the rotating disc cutter 31 transmits the cutting power to the speed-changing gear set (gear 1 4313, gear 2 4314, gear 3 4315, gear 4316) through the positioning ring 32. After speed change and torque increase, gear 4316 outputs high-speed rotational power, which drives the transmission rod 1 4325 to rotate. Then, through the universal transmission chain composed of connecting rod 4322, ball 4324, connecting head 4323 and telescopic sleeve 4321, the rotational motion is finally transmitted to the transmission rod 2 4326, driving the sleeve 424 and the telescopic sleeve 425 and the grinding wheel 426 to rotate at high speed.

[0055] Meanwhile, under the continuous action of the tension spring 4252, the telescopic rod 425, guided by the sliding guide of the limiting button 4251 within the limiting groove 4241, always applies a constant elastic pressure to the side of the disc cutter 31, pushing the grinding wheel 426 to press tightly against the side of the rotating disc cutter 31. If the disc cutter 31 experiences slight radial runout due to wear or vibration, the telescopic rod 425 can compensate by extending or retracting accordingly, ensuring that the grinding pressure remains basically constant. Thus, during the slitting process, the system can automatically utilize the rotational kinetic energy of the disc cutter 31 itself, and after speed change and transmission, drive the grinding wheel 426 to rotate at high speed. With the cooperation of constant spring pressure, it performs online, adaptive, and constant-pressure fine grinding on the side of the disc cutter 31, achieving deep finishing and maintenance of the CNC blade, significantly improving the blade's long-lasting sharpness and slitting quality.
