[0012] A use method of an adjustable slitting and cutting device for cold-rolled steel plate processing, the use method includes the following steps: When slitting and cutting the cold-rolled steel plate, lay the cold-rolled steel plate on the supporting roller on one side of the supporting plate, so that one side of the cold-rolled steel plate is located between the rotating cylinder and the material supporting assembly. Control the motor to work to drive the rotating cylinder to rotate, and the rotating cylinder drives the main cutter head and the secondary cutter head on the outer wall to rotate. Control the two electric hydraulic rods to extend to drive the adjusting rods to move downward, and the two adjusting rods drive the two bearing seats to move downward. The two bearing seats drive the rotating cylinder to move downward, so that the main cutter head and the secondary cutter head outside the rotating cylinder move downward and perform slitting and cutting on the cold-rolled steel plate. After the cold-rolled steel plate is stressed, it will squeeze the supporting rotating rod below. When the supporting rotating rod is stressed, it will drive the two sliding seats to move downward in the sliding groove through the two sleeve bearings and squeeze the spring, so that the sliding rods below the sliding seat slide into the bottom of the inner wall of the sliding seat. The spring force supports the sliding seat and gives an upward thrust to the supporting rotating rod, playing a role in buffering the supporting rotating rod and preventing the instantaneous force generated after the main cutter head and the secondary cutter head contact the cold-rolled steel plate from damaging the main cutter head and the secondary cutter head; When the cold-rolled steel plate is cut during the downward movement of the main blade and the auxiliary blade, the bottom of the main blade and the auxiliary blade will penetrate the cold-rolled steel plate and move into the central groove and the cutting groove outside the supporting rotating rod, giving the main blade and the auxiliary blade a certain amount of activity space to prevent the main blade and the auxiliary blade from directly contacting the supporting rotating rod, thereby ensuring the cutting stability. At this time, the cold-rolled steel plate after strip cutting is pushed to the other side of the rotating drum, and the rotating drum moves downward to contact the upper surface of the cold-rolled steel plate, and the lower surface of the cold-rolled steel plate contacts the outer surface of the supporting rotating rod. The cold-rolled steel plate is clamped by the rotating drum and the supporting rotating rod to improve the cutting stability. At the same time, as the rotating drum rotates, the cut cold-rolled steel plate will be sent out of the cutting range, so that the cold-rolled steel plate to be cut is moved under the main blade and the auxiliary blade, so as to realize the purpose of automatic conveying and synchronous cutting of the cold-rolled steel plate, and the height of the rotating drum is adjusted by adjusting the extension distance of the electric hydraulic rod, so that it is suitable for the cutting needs of cold-rolled steel plates of different thicknesses. When adjusting the cutting width, the screw at one end of the rotating drum is loosened to make the end of the screw disengage from the annular groove, and the handle at the other end of the screw is turned to make the handle drive the bidirectional lead screw to rotate through the rotating handle. During the rotation of the bidirectional lead screw, the nuts on both sides of its outside will move away from or approach each other, so that the nut drives the auxiliary knife disc to slide on the outside of the rotating drum through the slider, and the slider is supported and limited by the sliding hole, so as to improve the stability of the horizontal movement of the auxiliary knife disc and at the same time do not affect the rotating drum driving the auxiliary knife disc to perform rotating cutting work. During the movement, the distance between the auxiliary knife disc and the main knife disc changes, and the two auxiliary knife discs move synchronously, thereby improving the convenience of the adjustment operation and ensuring the adjustment accuracy of the two auxiliary knife discs. After completing the adjustment work, tighten the screw so that the end of the screw is clamped in the annular groove, so as to achieve the purpose of locking the rotation angle of the bidirectional lead screw, prevent the main knife disc and the auxiliary knife disc from rotating due to vibration, and help improve the precision of strip cutting.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the rotation of the bidirectional lead screw is driven by a rotating handle. During the rotation of the bidirectional lead screw, the nuts on both outer sides of it will move away from or close to each other, causing the nuts to drive the auxiliary cutter disc to slide outside the rotating cylinder through the sliders. At the same time, it does not affect the rotating cylinder to drive the auxiliary cutter disc to perform rotational cutting work. During the movement of the auxiliary cutter disc, the distance between it and the main cutter disc changes, and the two auxiliary cutter discs move synchronously, thereby improving the convenience of adjustment operation and ensuring the adjustment accuracy of the two auxiliary cutter discs. After the adjustment work is completed, the screw is tightened so that the end of the screw is clamped in the annular groove to achieve the purpose of locking the rotation angle of the bidirectional lead screw, preventing the main cutter disc and the auxiliary cutter disc from rotating automatically due to vibration. Abandoning the traditional method of changing the cutting width by replacing the cutter or using a complex mechanical adjustment structure, the cold-rolled steel plate is clamped by the rotating cylinder and the supporting rotating rod to improve the cutting stability. At the same time, as the rotating cylinder rotates, the cut cold-rolled steel plate will be sent out of the cutting range, moving the cold-rolled steel plate to be cut under the main cutter disc and the auxiliary cutter disc, achieving the purpose of automatic conveying and synchronous cutting of the cold-rolled steel plate. Moreover, by adjusting the extended distance of the electro-hydraulic rod, the height of the rotating cylinder is adjusted to meet the cutting requirements of cold-rolled steel plates with different thicknesses, reducing labor costs and shortening the production cycle; 2. In the present invention, the motor is controlled to work to drive the rotation of the rotating cylinder, and the rotating cylinder drives the main cutter disc and the auxiliary cutter disc on its outer wall to rotate. The two electro-hydraulic rods are controlled to extend to drive the adjusting rods to move downward, and the two adjusting rods drive the two bearing seats to move downward. The two bearing seats drive the rotating cylinder to move downward, causing the main cutter disc and the auxiliary cutter disc outside the rotating cylinder to move downward and perform strip cutting on the cold-rolled steel plate. After the cold-rolled steel plate is stressed, it will squeeze the supporting rotating rod below. When the supporting rotating rod is stressed, it will drive the two sliding seats to move downward in the sliding track through the two shaft sleeves and squeeze the spring, causing the sliding rod below the sliding seat to slide into the bottom of the inner wall of the sliding seat. The sliding seat is supported by the elastic force of the spring, giving an upward thrust to the supporting rotating rod, playing a buffering role for the supporting rotating rod to prevent the instantaneous force generated after the main cutter disc and the auxiliary cutter disc contact the cold-rolled steel plate from damaging the main cutter disc and the auxiliary cutter disc, and ensuring the stability of strip cutting.

Specific embodiments

[0015] The technical solutions of the present application will be further described in detail below in conjunction with specific embodiments.

[0016] As Figures 1-3 shown, an adjustable slitting and cutting device for cold-rolled steel plate processing includes a support plate 1. The number of support plates 1 is two, and four fixed rods 18 are fixedly connected to the opposite surfaces of the two support plates 1. An adjustment component 4 is fixedly connected to the top of the two support plates 1. A groove 5 is opened in the support plate 1, and the bottom end of the adjustment component 4 is slidably installed in the groove 5. The adjustment component 4 includes a top frame 401. The two sides of the top frame 401 are fixed to the top of the two support plates 1. Electric hydraulic rods 402 are respectively fixedly connected to the inner walls of the two ends of the top frame 401. The bottom end of the electric hydraulic rod 402 is fixedly connected to an adjustment rod 403. The bottom end of the adjustment rod 403 penetrates and slides at the bottom of the top frame 401 and is fixed with a bearing seat 404. Chutes 405 are respectively opened on both sides of the bearing seat 404, and the chutes 405 are slidably connected to the side walls of the groove 5. A machine base 6 is fixedly connected to one side of the bearing seat 404 of one of the adjustment components 4. A motor 7 is fixedly connected inside the machine base 6. The output shaft of the motor 7 is fixedly connected to a rotating cylinder 8, and both ends of the rotating cylinder 8 are sleeved and rotatably installed in the two bearing seats 404.

[0017] By controlling the elongation of two electro-hydraulic rods 402 to drive the adjusting rod 403 to move downward, the two adjusting rods 403 drive the two bearing seats 404 to move downward, and the two bearing seats 404 drive the rotating cylinder 8 to move downward. Moreover, the height of the rotating cylinder 8 is adjusted by adjusting the elongation distance of the electro-hydraulic rod 402 to make it suitable for the cutting requirements of cold-rolled steel plates with different thicknesses.

[0018] Fixed frames 2 are respectively fixed on both sides of the two support plates 1. Support rollers 3 are rotatably connected in the slot holes on both sides of the inner wall of the fixed frame 2. Guide rollers 17 are respectively arranged on both sides of the rotating cylinder 8. Both ends of the guide roller 17 are rotatably connected in the rotating seats fixed between the two support plates 1. By laying the cold-rolled steel plate on the support rollers 3 on one side of the support plate 1 and cooperating with the guide rollers 17 to support the cold-rolled steel plate, the friction when the cold-rolled steel plate moves is reduced, and thus the stability of the subsequent movement and cutting of the cold-rolled steel plate is improved.

[0019] As Figures 4-6 As shown in the figure, limit bearings 11 are respectively clamped on the inner walls at both ends of the rotating cylinder 8. The same bidirectional lead screw 10 is sleeved in the two limit bearings 11. A support bearing 14 is sleeved in the middle of the bidirectional lead screw 10, and the support bearing 14 is clamped in the middle of the rotating cylinder 8; A main cutter disc 15 is fixedly connected to the middle of the outer wall of the rotating cylinder 8, and cutting assemblies 16 are respectively sleeved on both sides of the outer wall of the rotating cylinder 8. The cutting assembly 16 includes a sub-cutter disc 161. The sub-cutter disc 161 is sleeved on the outer wall of the rotating cylinder 8. Three sliders 162 are fixed on the inner wall of the sub-cutter disc 161. Nuts 163 are fixed at one ends of the three sliders 162 close to each other. The nuts 163 are threadedly connected to the outside of the bidirectional lead screw 10; Two groups of sliding holes 9 along the length direction are respectively opened on the outer walls at both ends of the rotating cylinder 8, and the number of each group of sliding holes 9 is three. The sliders 162 penetrate and slide in the sliding holes 9. The nut 163 drives the sub-cutter disc 161 to slide outside the rotating cylinder 8 through the slider 162. The slider 162 is supported and limited by the sliding hole 9 to improve the stability of the horizontal movement of the sub-cutter disc 161, and at the same time does not affect the rotating cylinder 8 to drive the sub-cutter disc 161 to perform the rotating cutting work.

[0020] One end of the bidirectional lead screw 10 away from the motor 7 penetrates the rotating cylinder 8 and is fixedly connected with a locking assembly 13. An annular groove 12 is opened at the end of the rotating cylinder 8 close to the locking assembly 13. The locking assembly 13 includes a rotating handle 131. The rotating handle 131 is fixed at one end of the bidirectional lead screw 10. A screw 132 is threadedly penetrated and connected at the edge of the rotating handle 131. The end of the screw 132 is lapped in the annular groove 12, and a number of evenly spaced depressions are opened in the annular groove 12. Each time the end of the screw 132 is locked in the depression groove, the locking state is more reliable; The other end of the screw rod 132 is sleeved with a grip 133. By tightening the screw rod 132, the end of the screw rod 132 is clamped in the annular groove 12, so as to lock the rotation angle of the bidirectional lead screw 10 and prevent the main cutter disc 15 and the sub-cutter disc 161 from rotating automatically due to vibration.

[0021] As Figures 7-9 shown, a blank holding component 19 is arranged below the rotary cylinder 8, and slide ways 20 are opened at positions corresponding to the ends of the blank holding component 19 on the two support plates 1. The two ends of the blank holding component 19 are slidably installed in the slide ways 20; the blank holding component 19 includes a supporting rotating rod 191, and a plurality of evenly spaced cutting grooves 192 and a central groove 193 are respectively opened on both sides and in the middle of the outer wall of the supporting rotating rod 191. The main cutter disc 15 is located directly above the central groove 193, and the sub-cutter disc 161 is located above the cutting grooves 192.

[0022] Since the depressions are evenly arranged in the annular groove 12, each time when locking, from one depression to the next depression, the rotation angle of the bidirectional lead screw 10 is the same. At the same time, the nut 163 drives the sub-cutter disc 161 to move synchronously through the slider 162, so that the horizontal moving distance of the sub-cutter disc 161 is also the same. And the interval between a plurality of cutting grooves 192 is equal to the horizontal moving distance of the sub-cutter disc 161, so that the sub-cutter disc 161 is ensured to be exactly aligned with the cutting grooves 192 during the left and right movement.

[0023] Sleeve 194 is sleeved on both ends of the supporting rotating rod 191 respectively, a sliding seat 195 is clamped outside the sleeve 194, and the sliding seat 195 is slidably connected in the slide way 20. Two slide rods 196 are fixed at the bottom of the sliding seat 195, the bottom ends of the slide rods 196 slide through the bottom of the inner wall of the slide way 20, a spring 197 is sleeved outside the slide rods 196, the top end of the spring 197 is fixed to the bottom of the sliding seat 195, and the bottom end of the spring 197 is fixedly connected to the bottom of the inner wall of the slide way 20.

[0024] Due to the provision of the cutting grooves 192 and the central groove 193, the bottoms of the main cutter disc 15 and the sub-cutter disc 161 will penetrate the cold-rolled steel plate and move into the central groove 193 and the cutting grooves 192 outside the supporting rotating rod 191, giving a certain moving space to the main cutter disc 15 and the sub-cutter disc 161, preventing the main cutter disc 15 and the sub-cutter disc 161 from directly contacting the supporting rotating rod 191, and thus ensuring the stability of cutting; when the supporting rotating rod 191 is pressed, it will drive the two sliding seats 195 to move downward in the slide way 20 through the two sleeves 194 and compress the spring 197, so that the slide rods 196 below the sliding seats 195 slide into the bottom of the inner wall of the sliding seats 195, and the spring 197 supports the sliding seats 195 through its elastic force, giving an upward thrust to the supporting rotating rod 191, playing a role in buffering the supporting rotating rod 191 and preventing the instantaneous force generated after the main cutter disc 15 and the sub-cutter disc 161 contact the cold-rolled steel plate from damaging the main cutter disc 15 and the sub-cutter disc 161.

[0025] A method for using an adjustable slitting and cutting device for cold-rolled steel plate processing, the method comprising the following steps: When slitting and cutting a cold-rolled steel plate, lay the cold-rolled steel plate on the supporting roller rod 3 on one side of the supporting plate 1, so that one side of the cold-rolled steel plate is located between the rotating cylinder 8 and the material supporting assembly 19. Control the motor 7 to work to drive the rotating cylinder 8 to rotate. The rotating cylinder 8 drives the main cutter disc 15 and the auxiliary cutter disc 161 on the outer wall to rotate. Control the two electro-hydraulic rods 402 to extend to drive the adjusting rods 403 to move downward. The two adjusting rods 403 drive the two bearing seats 404 to move downward. The two bearing seats 404 drive the rotating cylinder 8 to move downward, so that the main cutter disc 15 and the auxiliary cutter disc 161 outside the rotating cylinder 8 move downward and perform slitting and cutting on the cold-rolled steel plate. After the cold-rolled steel plate is stressed, it will squeeze the supporting rotating rod 191 below. When the supporting rotating rod 191 is stressed, it will drive the two sliding seats 195 to move downward in the sliding track 20 through the two shaft sleeves 194 and squeeze the spring 197, so that the sliding rod 196 below the sliding seat 195 slides into the bottom of the inner wall of the sliding seat 195. The spring 197 supports the sliding seat 195 with its elastic force, giving an upward thrust to the supporting rotating rod 191, playing a role in buffering the supporting rotating rod 191 and preventing the instantaneous force generated after the main cutter disc 15 and the auxiliary cutter disc 161 contact the cold-rolled steel plate from damaging the main cutter disc 15 and the auxiliary cutter disc 161; When cutting the cold-rolled steel plate during the downward movement of the main cutter disc 15 and the auxiliary cutter disc 161, the bottoms of the main cutter disc 15 and the auxiliary cutter disc 161 will penetrate the cold-rolled steel plate and move into the central groove 193 and the cutting groove 192 outside the supporting rotating rod 191, giving a certain movement space to the main cutter disc 15 and the auxiliary cutter disc 161 to prevent the main cutter disc 15 and the auxiliary cutter disc 161 from directly contacting the supporting rotating rod 191, thereby ensuring the stability of cutting. At this time, push the cold-rolled steel plate after slitting and cutting to the other side of the rotating cylinder 8. When the rotating cylinder 8 moves downward, it will contact the upper surface of the cold-rolled steel plate, and the lower surface of the cold-rolled steel plate will contact the outer surface of the supporting rotating rod 191. The cold-rolled steel plate is clamped by the rotating cylinder 8 and the supporting rotating rod 191 to improve the cutting stability. At the same time, as the rotating cylinder 8 rotates, the cut cold-rolled steel plate will be sent out of the cutting range, so that the cold-rolled steel plate to be cut moves under the main cutter disc 15 and the auxiliary cutter disc 161, realizing the purpose of automatic conveying and synchronous cutting of the cold-rolled steel plate. Moreover, the height of the rotating cylinder 8 is adjusted by adjusting the extension distance of the electro-hydraulic rod 402 to make it suitable for the cutting requirements of cold-rolled steel plates with different thicknesses; When adjusting the cutting width, loosen the screw 132 at one end of the rotating cylinder 8 to make the end of the screw 132 disengage from the annular groove 12, and rotate the grip 133 at the other end of the screw 132. The grip 133 drives the bidirectional lead screw 10 to rotate through the rotating handle 131. During the rotation of the bidirectional lead screw 10, the nuts 163 on both sides of its outside will move away from or close to each other, so that the nuts 163 drive the auxiliary cutter head 161 to slide outside the rotating cylinder 8 through the sliders 162. The sliders 162 are supported and limited through the sliding holes 9 to improve the stability of the horizontal movement of the auxiliary cutter head 161, and at the same time, it does not affect the rotating cylinder 8 to drive the auxiliary cutter head 161 to perform rotary cutting work. During the movement of the auxiliary cutter head 161, the distance between it and the main cutter head 15 changes, and the two auxiliary cutter heads 161 move synchronously, thereby improving the convenience of the adjustment operation and ensuring the adjustment accuracy of the two auxiliary cutter heads 161. After the adjustment work is completed, tighten the screw 132 to make the end of the screw 132 snap into the annular groove 12, so as to achieve the purpose of locking the rotation angle of the bidirectional lead screw 10 and prevent the main cutter head 15 and the auxiliary cutter head 161 from rotating automatically due to vibration, which is beneficial to improving the slitting cutting accuracy.

8. A method of using an adjustable slitting and cutting device for cold-rolled steel sheet processing, according to any one of claims 1-7, an adjustable slitting and cutting device for cold-rolled steel sheet processing, characterized in that, The usage method includes the following steps: When strip cutting cold-rolled steel sheets, the cold-rolled steel sheets are laid on the support roller rods (3) on one side of the support plate (1), with one side of the cold-rolled steel sheets located between the rotating cylinder (8) and the material supporting assembly (19). By controlling the operation of the motor (7), it drives the rotating cylinder (8) to rotate. The rotating cylinder (8) then drives the main cutter disc (15) and the auxiliary cutter disc (161) on its outer wall to rotate. Control the two electro-hydraulic rods (402) to extend, which drives the adjusting rods (403) to move downward. The two adjusting rods (403) drive the two bearing seats (404) to move downward. The two bearing seats (404) drive the rotating cylinder (8) to move downward, so that the main cutter disc (15) and the auxiliary cutter disc (161) outside the rotating cylinder (8) move downward and perform strip cutting on the cold-rolled steel sheets. After the cold-rolled steel sheets are stressed, they will squeeze the supporting rotating rod (191) below. When the supporting rotating rod (191) is stressed, it will drive the two sliding seats (195) to move downward in the slideway (20) through the two shaft sleeves (194) and squeeze the spring (197), so that the sliding rod (196) below the sliding seat (195) slides into the bottom of the inner wall of the sliding seat (195). The spring (197) supports the sliding seat (195) with its elastic force, giving an upward thrust to the supporting rotating rod (191), playing a buffering role for the supporting rotating rod (191) and preventing the instantaneous force generated after the main cutter disc (15) and the auxiliary cutter disc (161) contact the cold-rolled steel sheets from damaging the main cutter disc (15) and the auxiliary cutter disc (161). When cutting the cold-rolled steel sheets during the downward movement of the main cutter disc (15) and the auxiliary cutter disc (161), the bottoms of the main cutter disc (15) and the auxiliary cutter disc (161) will penetrate the cold-rolled steel sheets and move into the central groove (193) and the cutting groove (192) outside the supporting rotating rod (191), giving a certain movement space to the main cutter disc (15) and the auxiliary cutter disc (161) to prevent the main cutter disc (15) and the auxiliary cutter disc (161) from directly contacting the supporting rotating rod (191), thereby ensuring the stability of cutting. At this time, the strip-cut cold-rolled steel sheets are pushed to the other side of the rotating cylinder (8). When the rotating cylinder (8) moves downward, it will contact the upper surface of the cold-rolled steel sheets, and the lower surface of the cold-rolled steel sheets will contact the outer surface of the supporting rotating rod (191). The cold-rolled steel sheets are clamped by the rotating cylinder (8) and the supporting rotating rod (191) to improve the cutting stability. At the same time, as the rotating cylinder (8) rotates, the cut cold-rolled steel sheets are sent out of the cutting range, and the cold-rolled steel sheets to be cut are moved below the main cutter disc (15) and the auxiliary cutter disc (161), realizing the purpose of automatic conveying and synchronous cutting of the cold-rolled steel sheets. Moreover, the height of the rotating cylinder (8) is adjusted by adjusting the extension distance of the electro-hydraulic rod (402) to make it suitable for the cutting requirements of cold-rolled steel sheets with different thicknesses. When adjusting the cutting width, loosen the screw rod (132) at one end of the rotating cylinder (8) to disengage the end of the screw rod (132) from the annular groove (12), and rotate the grip (133) at the other end of the screw rod (132) so that the grip (133) drives the bidirectional lead screw (10) to rotate through the rotating handle (131). During the rotation of the bidirectional lead screw (10), the nuts (163) on both outer sides of it will move away from or close to each other, so that the nuts (163) drive the auxiliary cutter disc (161) to slide outside the rotating cylinder (8) through the sliders (162). The sliders (162) are supported and limited through the sliding holes (9) to improve the stability of the horizontal movement of the auxiliary cutter disc (161), and at the same time, it does not affect the rotating cylinder (8) to drive the auxiliary cutter disc (161) to perform rotational cutting work. During the movement of the auxiliary cutter disc (161), the distance between it and the main cutter disc (15) changes, and the two auxiliary cutter discs (161) move synchronously, thereby improving the convenience of the adjustment operation and ensuring the adjustment accuracy of the two auxiliary cutter discs (161). After the adjustment work is completed, tighten the screw rod (132) so that the end of the screw rod (132) is clamped in the annular groove (12) to achieve the purpose of locking the rotation angle of the bidirectional lead screw (10), preventing the main cutter disc (15) and the auxiliary cutter disc (161) from rotating automatically due to vibration, which is beneficial to improving the strip cutting accuracy.
