Description

Technical Field

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

[0002] In the field of sheet metal processing, slitting equipment is the core equipment for realizing the slitting of wide sheets, and its performance directly affects the precision, quality and production efficiency of the finished products.

[0003] Existing slitting equipment still has many shortcomings in practical applications: Firstly, it is difficult to balance processing precision and finished product quality. Defects such as wrinkles and bends during the feeding of metal sheets, as well as local deformations during the cutting process, can easily lead to deviations in slitting dimensions. At the same time, burrs and sharp edges are common after cutting, which not only affect the appearance quality but also require additional post-processing, increasing production costs.

[0004] Secondly, the adaptability and adjustment flexibility are insufficient. The cutting blades of traditional equipment are mostly fixed installation structures, and the blade spacing adjustment is cumbersome or impossible. When facing processing requirements of different width specifications, it is necessary to frequently change the blades or adjust the equipment, resulting in long changeover time, low production efficiency, and difficulty in adapting to diverse processing scenarios.

[0005] Third, there are shortcomings in safety protection. Untreated sharp edges can easily cause cuts and injuries during handling and subsequent use.

[0006] Therefore, a longitudinal cutting device for processing metal sheets is proposed. Utility Model Content

[0007] The purpose of this invention is to solve the above problems by proposing a longitudinal cutting device that can simultaneously address the issues of leveling accuracy, cut quality, adjustment flexibility, and safety protection.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a longitudinal cutting device for processing metal sheets, comprising a longitudinal cutting device body, wherein a pair of first leveling rollers for initial leveling of the metal sheet are rotatably mounted at the front end of the longitudinal cutting device body, and a pair of second leveling rollers for secondary leveling of the metal sheet are rotatably mounted near the middle of the longitudinal cutting device body; a first grooving roller is rotatably mounted between the first and second leveling rollers inside the longitudinal cutting device body, and a second grooving roller is rotatably mounted at the rear end of the longitudinal cutting device body; a plurality of cutting annular blades for longitudinal cutting of the metal sheet are evenly distributed along the axial direction on the outer wall of the first grooving roller, and a plurality of annular grinding discs for grinding the cutting edge are evenly distributed along the axial direction on the outer wall of the second grooving roller. The outer walls of both the No. 1 and No. 2 grooving rollers are provided with three axially extending and evenly distributed limiting grooves. Each limiting groove has multiple screw holes evenly distributed along its length for fixing components. The inner walls of both the cutting ring blade and the ring grinding disc are integrally formed with three circumferentially distributed sliders. The sliders slide and adapt to the limiting grooves, and both ends of the sliders have through holes that correspond to the screw holes. Hex socket screws for fixing the sliders in the limiting grooves are installed in the through holes. The outer walls of the longitudinal cutting equipment body are all fixedly equipped with motors for driving the corresponding roller shafts to rotate at the ends of the No. 1 leveling roller, No. 2 leveling roller, No. 1 grooving roller, and No. 2 grooving roller. A control box for controlling the operation of the equipment is fixedly installed at one end of the rear surface of the longitudinal cutting equipment body.

[0009] Preferably, the outer side wall of the slitting equipment body is detachably fitted with a maintenance cover for equipment maintenance. The maintenance cover is fixedly connected to the slitting equipment body by fixing screws. Removing the maintenance cover allows for the maintenance of the internal components of the slitting equipment body, as well as the maintenance or replacement of the No. 1 leveling roller, No. 2 leveling roller, No. 1 grooving roller, No. 2 grooving roller, and motor. The bottom surface of the slitting equipment body has three integrally formed mounting strips evenly distributed along its length. Each mounting strip has a bolt pre-drilled through hole for fixing the slitting equipment body to the mounting foundation.

[0010] Preferably, the axial distribution position of the annular grinding disc on the second grooving roller corresponds one-to-one with the axial distribution position of the cutting annular blade on the first grooving roller, ensuring that the annular grinding disc can accurately grind the cut formed by the cutting annular blade.

[0011] Preferably, the slider is slidably mounted in the limiting groove, and the internal hexagon screw passes through the through hole of the slider and is threaded to the corresponding screw hole. The axial position of the cutting ring blade and the ring grinding disc on the corresponding roller shaft is locked by tightening the internal hexagon screw.

[0012] Preferably, the output end of each motor is fixedly connected to one end of the corresponding No. 1 leveling roller, No. 2 leveling roller, No. 1 grooving roller or No. 2 grooving roller. After the motor is started, it can drive the corresponding roller shaft to rotate around its own axis, and the rotation direction of each roller shaft is adapted to the conveying direction of the metal sheet.

[0013] Preferably, the motor is electrically connected to the control box.

[0014] The beneficial effects of this utility model are as follows: Through the design of this slitting device, the specific beneficial effects are as follows: High processing precision and excellent finished product quality: The double leveling rollers (leveling roller No. 1 and leveling roller No. 2) correct the board in steps, eliminating wrinkles and cutting deformation, which is conducive to subsequent tight winding and use; the cutting ring blades and ring grinding discs are positioned one-to-one, accurately longitudinally cutting and removing burrs, improving the smoothness of the board cut and the appearance quality. Flexible adjustment and strong adaptability: The limit slide, slider and internal hex screw can be used to flexibly adjust the position of the cutting blade and grinding disc to meet the processing needs of metal plates of different widths and have a wide range of applications.

[0015] Safety protection is in place: the ring-shaped grinding disc removes sharp edges of the material to prevent personnel from being scratched during handling and use; all components are firmly fixed and there is no deviation during high-speed operation, reducing the risk of equipment operation safety.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. 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 protection scope of the present utility model.

[0019] See Figure 1-4 As shown, the main body 1 of the slitting equipment serves as the basic frame and support carrier of the entire equipment, providing installation positions for the No. 1 leveling roller 2, No. 2 leveling roller 3, No. 1 grooving roller 4, No. 2 grooving roller 5, motor 12, and control box 13, ensuring the stability and relative position accuracy of each component during operation. Meanwhile, its outer wall is detachably fitted with an inspection cover. Figure 1 The main body of the longitudinal cutting equipment has a rectangular cover plate on the top, sides, front and rear surfaces (motor 12) to facilitate the maintenance of internal components by staff. Three mounting strips on the bottom surface... Figure 1 The main body of the longitudinal cutting equipment 1 has a perforated strip on the bottom surface and pre-drilled bolt holes. Figure 1 The through holes on the bottom of the main body 1 of the longitudinal cutting equipment can fix the equipment on the installation foundation, ensuring that the equipment does not shift during operation.

[0020] There is a pair of leveling rollers 2, which are rotatably mounted inside the front end of the main body 1 of the slitting equipment. Their main function is to perform preliminary leveling on the metal sheet that has just entered the equipment. By rotating and contacting the metal sheet, they initially correct unevenness such as wrinkles and bends on the surface of the sheet, providing a flat sheet base for the subsequent slitting process and ensuring the cutting accuracy of the subsequent cutting ring blade 6.

[0021] The second leveling roller 3 is also a pair, rotatably mounted inside the main body 1 of the slitting equipment near the center, located after the first grooving roller 4. Its function is to perform secondary leveling on the metal sheet after slitting by the first grooving roller 4. Since the slitting process may cause local deformation and edge burrs on the sheet, the second leveling roller 3 can effectively eliminate these deformations and flatten some burrs by rotating and pressing, further improving the flatness of the sheet and creating good conditions for the subsequent precise grinding by the annular grinding disc 7.

[0022] The No. 1 grooving roller 4 is rotatably mounted inside the main body 1 of the slitting equipment between the No. 1 leveling roller 2 and the No. 2 leveling roller 3. Multiple cutting ring blades 6 are evenly distributed along the axial direction on its outer wall, and three axially extending and evenly distributed limiting grooves 8 are provided. Its core function is to serve as the mounting carrier for the cutting ring blades 6. Its own rotation drives the cutting ring blades 6 to rotate synchronously, using the cutting ring blades 6 to perform sliding operations on the pre-leveled metal sheet, cutting the metal sheet into strips of the required width. Simultaneously, the limiting grooves 8 provide sliding and limiting space for the slider 10 of the cutting ring blades 6, ensuring the stability of the cutting ring blades 6 during axial adjustment.

[0023] The second grooving roller 5 is rotatably mounted inside the rear end of the main body 1 of the longitudinal cutting equipment. Multiple annular grinding discs 7 are evenly distributed axially on its outer wall, and three axially extending and evenly distributed limiting grooves 8 are also provided. Its main function is to serve as the mounting carrier for the annular grinding discs 7. By rotating itself, it drives the annular grinding discs 7 to rotate. Since the axial distribution of the annular grinding discs 7 on the second grooving roller 5 corresponds one-to-one with the position of the cutting annular blade 6 on the first grooving roller 4, it can accurately grind the cut surface of the plate formed by the cutting annular blade 6 after longitudinal cutting, removing burrs, sharp edges, etc., improving the smoothness and safety of the plate cut surface. The limiting grooves 8 provide sliding and limiting for the slider 10 of the annular grinding disc 7, ensuring the accurate positioning of the annular grinding disc 7.

[0024] The cutting ring blade 6 is installed in the limiting groove 8 of the first grooving roller 4, and three sliders 10 are integrally formed on the inner side wall. Its core function is to directly longitudinally cut the metal sheet. Driven by the first grooving roller 4, it rotates at high speed and, when in contact with the metal sheet, uses its sharp cutting edge to cut the sheet axially, realizing the slitting of the metal sheet and meeting the processing needs of sheets of different widths. The sliders 10, together with the limiting groove 8 and the internal hex screws 11, fix and adjust their position on the first grooving roller 4.

[0025] The annular grinding disc 7 is assembled in the limiting groove 8 of the second grooving roller 5, and three sliders 10 are integrally formed on the inner side wall. Its main function is to grind the cut edge of the plate after longitudinal cutting by the cutting annular blade 6. Rotating under the drive of the second grooving roller 5, when it comes into contact with the cut edge of the plate, it grinds the burrs and uneven parts at the cut edge through its own grinding surface, so that the cut edge is smooth and without sharp edges. This not only improves the appearance quality of the plate, but also avoids the risk of personnel being scratched during subsequent use or handling. The design of the sliders 10 enables them to be fixed in position and precisely aligned on the second grooving roller 5.

[0026] Limiting grooves 8 are respectively formed on the outer walls of the first grooving roller 4 and the second grooving roller 5, extending axially along the roller shaft and evenly distributed in three places. Multiple screw holes 9 are evenly formed along the length of the grooves inside. Their function is to provide a sliding track and limiting structure for the slider 10 of the cutting ring blade 6 and the ring grinding disc 7, restricting the rotation of the slider 10 in the circumferential direction of the roller shaft, ensuring that the cutting ring blade 6 and the ring grinding disc 7 can only move axially along the roller shaft to adjust their position. Simultaneously, through cooperation with the slider 10, they ensure the installation stability of the cutting ring blade 6 and the ring grinding disc 7 on the roller shaft, preventing them from shifting during high-speed rotation cutting or grinding. The screw holes 9 provide connection positions for the internal hexagon screws 11, achieving component fixation.

[0027] Screw holes 9 are evenly spaced along the length of the limiting slide groove 8, corresponding to the through holes on the slider 10. Their function is to serve as threaded connection points for the hexagon socket screws 11. When the slider 10 is adjusted to the appropriate position within the limiting slide groove 8, the hexagon socket screws 11 pass through the through holes of the slider 10 and are threadedly connected to the corresponding screw holes 9. The tightening force of the screws firmly fixes the slider 10 within the limiting slide groove 8, thereby locking the axial position of the cutting ring blade 6 and the ring grinding disc 7 on the corresponding roller shaft, preventing displacement of the components during operation.

[0028] The slider 10 is integrally formed on the inner wall of the cutting ring blade 6 and the ring grinding disc 7. Three sliders are evenly distributed circumferentially and slide to fit the limiting groove 8. Through holes corresponding to screw holes 9 are opened at both ends. Its function is to connect the cutting ring blade 6, the ring grinding disc 7 and the corresponding roller shaft. By sliding in the limiting groove 8, the cutting ring blade 6 and the ring grinding disc 7 are driven to move axially along the roller shaft, thereby adjusting the position of the components to meet the processing requirements of metal plates of different widths. At the same time, the through holes allow the internal hexagon screws 11 to pass through, which, together with the screw holes 9, complete the fixation of the components and ensure the stability of the cutting and grinding operations.

[0029] The hex socket screw 11 is fitted into the through hole of the slider 10 and threaded into the screw hole 9 of the limiting groove 8. Its main function is to fix the cutting ring blade 6, the ring grinding disc 7, and the corresponding roller shaft. After the cutting ring blade 6 and the ring grinding disc 7 are adjusted to the appropriate position, the hex socket screw 11 is passed through the through hole of the slider 10 and screwed into the screw hole 9. Through the tightening action of the screw, the slider 10 is locked in the limiting groove 8, thereby fixing the position of the cutting ring blade 6 and the ring grinding disc 7, preventing positional displacement due to vibration, force, or other factors during equipment operation, and ensuring cutting and grinding accuracy.

[0030] Motor 12 is fixedly mounted on the outer wall of the main body 1 of the longitudinal cutting equipment, corresponding to the ends of the first leveling roller 2, the second leveling roller 3, the first grooving roller 4, and the second grooving roller 5. Its output end is fixedly connected to one end of the corresponding roller shaft. It is the power source for the rotation of each roller shaft of the equipment. After starting, it can drive the corresponding roller shaft to rotate around its own axis. The rotation direction of each motor 12 driving the roller shaft is adapted to the conveying direction of the metal sheet. By providing rotational power to the first leveling roller 2 and the second leveling roller 3, the sheet is leveled. By providing power to the first grooving roller 4 and the second grooving roller 5, the cutting ring blade 6 and the ring grinding disc 7 are driven to complete the cutting and grinding operations, ensuring the smooth progress of the entire processing flow.

[0031] The control box 13 is fixedly mounted on one end of the rear surface of the main body 1 of the slitting equipment. Its main function is to control and regulate the operation of the entire slitting equipment. The operator can start, stop, and adjust the speed of the motor 12 through the control box 13, thereby controlling the rotation state of each roller shaft to ensure the quality and efficiency of the slitting process of the metal sheet.

[0032] In use, the metal sheet first passes through a pair of leveling rollers 2 for initial leveling, and is then longitudinally cut by the cutting ring blade 6 on the first grooving roller 4. Subsequently, it is leveled by the second leveling roller 3. The deformation and burrs generated by the longitudinal cutting are leveled, and the cutting edge is polished by the ring grinding disc 7. The longitudinally cut edge of the metal sheet is then discharged.

[0033] The operation process of this utility model is as follows: When the parameters are preset and the equipment is started, the speed parameters of each motor 12 are pre-adjusted according to the width requirements of the metal sheet to be processed through the control box 13 on the rear surface of the longitudinal cutting equipment body 1 to ensure that they are compatible with the conveying speed of the sheet; after the parameters are set, the control box 13 is started to drive the No. 1 leveling roller 2, No. 2 leveling roller 3, No. 1 grooving roller 4, and No. 2 grooving roller 5 to rotate synchronously.

[0034] During the feeding and initial leveling of the sheet metal, one end of the sheet metal to be processed is aligned with the gap between the No. 1 leveling rollers 2 at the front end of the main body 1 of the slitting equipment, and it is slowly fed into the equipment. Under the rotation and extrusion action of the pair of No. 1 leveling rollers 2, the unevenness problems such as surface wrinkles and bends of the sheet metal are initially corrected, forming a flat sheet metal state for the next process.

[0035] During the longitudinal cutting of sheet metal, the pre-leveled sheet metal continues to be conveyed and enters the area of ​​the first grooving roller 4 between the first leveling roller 2 and the second leveling roller 3. The first grooving roller 4 drives the cutting ring blade 6 on the outer wall to rotate and squeeze, and uses the blade edge to longitudinally cut the sheet metal into strips of a preset width, thus completing the longitudinal cutting operation.

[0036] After the plate is leveled for the second time, the longitudinally cut metal plate immediately enters the area of ​​the second leveling roller 3 located behind the first grooving roller 4; the pair of second leveling rollers 3 eliminate the local deformation of the plate generated during the longitudinal cutting process by rotating and pressing, and flatten some of the burrs at the cut, further improving the flatness of the plate and preparing it for subsequent grinding.

[0037] During the cutting and grinding process and the finished product discharge, the metal sheet that has completed the secondary leveling continues to be conveyed to the rear end of the main body 1 of the longitudinal cutting equipment, to the area of ​​the No. 2 grooving roller 5. The No. 2 grooving roller 5 drives the annular grinding disc 7 to rotate. Since the annular grinding disc 7 and the cutting annular blade 6 are in one-to-one correspondence, the cutting edge of the sheet can be precisely ground to remove burrs and sharp edges. The metal sheet strip after grinding is naturally discharged from the rear end of the equipment, completing the entire longitudinal cutting process.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of protection of the present invention is defined by the appended claims and their equivalents.
