Abstract
Description
Technical Field
[0001] This invention relates to the field of sheet cutting technology, and more particularly to a silicon steel sheet longitudinal cutting device. Background Technology
[0002] Slitting silicon steel sheets involves cutting cold-rolled silicon steel sheets into multiple strips according to specific specifications for subsequent processing and use. During the slitting process, the silicon steel sheets themselves have uneven thickness and inconsistent material hardness, which easily leads to curling. Improper settings of parameters such as cutting speed, cutting depth, and cutting angle, or insufficient precision of the cutting equipment, can also cause curling. Maintaining high-precision cutting is difficult or costly to achieve in current operations. Therefore, slight curling is corrected by pressing with rollers. However, due to the wide pressing range, the sheet material on the side of the curled edge can easily cover the curled surface during pressing, causing localized bulging at the edge. Furthermore, the cutting blade is prone to overheating during cutting, leading to damage. Additionally, debris adhering to the surface of the cutting blade can also cause damage.

[0016] 3. Two inclined guide plates direct the airflow forward and downward, blowing air towards the cutting blade position to disperse debris at that position, preventing debris from affecting the cutting and causing problems such as damage to the cutting blade and uneven cutting edges of the sheet.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0027] like Figures 1-8 The illustrated silicon steel sheet longitudinal slitting device includes a base frame 1. A connecting frame 2 is fixedly installed on the upper end of the base frame 1. Several conveying rollers 3 are rotatably installed on the inner side of the connecting frame 2. A blade template 6 is fixedly installed on the inner side of the connecting frame 2 near the space between two conveying rollers 3. A rotating shaft 7 is connected to the upper end of the connecting frame 2, corresponding to the area above the blade template 6, via a first lifting mechanism. Several cutting blades 8 are fixedly sleeved on the outer surface of the rotating shaft 7. A convex strip 2 is connected to the upper end of the connecting frame 2, near the rear of the rotating shaft 7, via a second lifting mechanism. 0. Several sleeve blocks 21 are slidably fitted on the outer surface of the convex strip 20. A connecting steel 27 is fixedly connected to the lower end of the sleeve block 21. A pressure roller 29 is rotatably installed on the lower end of the connecting steel 27. A concave box 23 is fixedly installed on the front surface of the sleeve block 21 through a ventilation mechanism. Several air outlets 24 are opened on the inner surface of the concave box 23. Inclined guide plates 25 are fixedly connected to the inner walls on both sides of the concave box 23. Inclined end plates 26 are respectively provided at the front end of the inclined guide plates 25. The lower rear edge of each cutting blade 8 is located inside the concave box 23. A strip-shaped opening is opened on the surface of the blade template 6 so that the lower edge of the cutting blade 8 can enter when it moves down, preventing the cutting blade 8 from having a hard collision with the surface of the blade template 6.
[0028] like Figure 4 , Figure 5As shown, the first lifting mechanism includes a base 19 fixedly mounted on one side surface of the connecting frame 2. A telescopic cylinder 18 is fixedly mounted on the upper surface of the base 19. A motor base 16 is fixedly connected to the telescopic end of the telescopic cylinder 18. A first motor 17 is fixedly mounted on the upper surface of the motor base 16. One end of the rotating shaft 7 rotatably passes through the motor base 16, and the other end of the rotating shaft 7 is fixedly connected to the output shaft of the first motor 17. A first fixed seat 15 is fixedly mounted on the other side surface of the connecting frame 2. Several first guide rods 14 slide through the upper surface of the first fixed seat 15. The upper ends of the several first guide rods 14 are fixedly connected to a first lifting plate 13. One side of the first lifting plate 13 is connected to the other end of the rotating shaft 7 through a docking mechanism. The first motor 17 drives the rotating shaft 7 to rotate, and the telescopic cylinder 18 extends and retracts, causing the motor base 16 to move up and down, thereby changing the cutting depth of the cutting blade 8 on the silicon steel sheet. The first guide rods 14 move up and down relative to the first fixed seat 15, improving stability.
[0029] like Figure 2 , Figure 3 , Figure 6 As shown, the docking mechanism includes a reinforcing bolt 12 that slides through one side surface of the first lifting plate 13. One end of the reinforcing bolt 12 is threaded into the end face of the rotating shaft 7. After fixing the rotating shaft 7, the reinforcing bolt 12 is rotated and removed, allowing the rotating shaft 7 to move upwards as much as possible. This allows the cutting blade 8 to be removed laterally for easy replacement. The specific replacement of the cutting blade 8 is as follows:
[0030] like Figure 6 As shown, a strip-shaped groove 11 is formed on the outer surface of the rotating shaft 7. A limiting seat 9 is respectively fitted on both sides of each cutting blade 8 on the outer surface of the rotating shaft 7. A locking bolt 10 is threaded through the outer surface of the limiting seat 9, and the end of the locking bolt 10 is embedded in the inner side of the strip-shaped groove 11. After loosening the locking bolt 10, the limiting seat 9 and the cutting blade 8 can be moved laterally for easy removal and replacement.
[0031] like Figure 4 ,and Figure 5As shown, the second lifting mechanism includes a support plate 35 fixedly installed on the upper surface of one side of the connecting frame 2. An adjusting cylinder 34 is fixedly installed on the upper surface of the support plate 35. An adjusting seat 33 is fixedly connected to the telescopic end of the adjusting cylinder 34. One end of the convex strip 20 is fixedly connected to one side surface of the adjusting seat 33. A second fixed seat 38 is fixedly installed on the upper surface of the other side of the connecting frame 2. Several second guide rods 37 slide through the upper surface of the second fixed seat 38. The upper ends of the several second guide rods 37 are jointly fixedly connected to a second lifting plate 36. The other end of the convex strip 20 is fixedly connected to the side surface of the second lifting plate 36. By controlling the telescopic extension and retraction of the adjusting cylinder 34, the convex strip 20 moves up and down, adjusting the pressure of the pressure roller 29 on the surface of the silicon steel sheet, making it more flexible to use. During adjustment, the second guide rods 37 move up and down relative to the second fixed seat 38, ensuring the stability of the movement on that side.
[0032] like Figure 4 , Figure 5 , Figure 6 As shown, the ventilation mechanism includes an inflation pipe 31 that is fixedly inserted through one side surface of the adjustable seat 33. A connecting rod 32 is fixedly connected between the inflation pipe 31 and the second lifting plate 36. Several branch pipes 30 are fixedly connected to the outer surface of the inflation pipe 31. The branch pipes 30 are fixedly inserted through the surface of the connecting steel 27, and the ends of the branch pipes 30 are fixedly embedded in the lower surface of the concave box 23. The branch pipes 30 are made of rubber tubing so that the rubber tubing will not be damaged when the concave box 23 is adjusted laterally. The inflation pipe 31 is made of metal tubing.
[0033] like Figure 7 , Figure 8 As shown, a locating bolt 22 is threaded through the rear surface of the sleeve 21, and the front end of the locating bolt 22 abuts against the surface of the convex strip 20. By tightening the locating bolt 22, the sleeve 21 can be kept stable.
[0034] like Figure 1 , Figure 4 As shown, a take-up roller 5 is rotatably mounted at the inner rear end of the connecting frame 2. A second motor 39 is fixedly mounted on the inner side of the connecting frame 2, near the front of the take-up roller 5. A transmission wheel 40 is fixedly mounted on the output shaft of the second motor 39 and one end of the take-up roller 5, respectively. Both transmission wheels 40 are rotatably mounted on one side surface of the connecting frame 2. A tensioning wheel 41 is rotatably mounted on one side surface of the connecting frame 2, near the space between the two transmission wheels 40. A transmission belt 42 is fitted onto the outer surfaces of the tensioning wheel 41 and the two transmission wheels 40. A material roller 4 is rotatably embedded at the front end of the upper surface of the connecting frame 2. The second motor 39 provides power for the rotation of the take-up roller 5.
[0035] like Figure 7 As shown, a pressure seat 28 is fixedly installed at the lower end of the connecting steel 27, and the pressure roller 29 is rotatably embedded in the inner side of the pressure seat 28, thereby realizing the rotatable installation of the pressure roller 29.
[0036] In use, the user places the rolled material on the feed roller 4 and pulls the silicon steel sheet backward. After passing through several conveyor rollers 3, the edge is fixed to the surface of the take-up roller 5. During use, under the action of the second motor 39, the transmission wheel 40 and the transmission belt 42 drive the take-up roller 5 to rotate, driving the silicon steel sheet for transmission. Figure 8 As shown, the pieces are cut at the bottom of the cutting blade 8. After cutting, the edges of adjacent pieces are pressed by the pressure roller 29, which promptly restores the rolled edges. The concentrated pressure on the edges prevents the surface of the pieces from bulging during pressing.
[0037] During the slitting process, air is continuously injected into one end of the air inlet pipe 31. The air enters the concave box 23 through the branch pipe 30 and is discharged through the air outlet 24. It is blown to the rear of the cutting blade 8, that is, the position where the cutting action has just been completed, to cool it down in time and prevent damage to the position due to overheating during cutting. At the same time, the two inclined guide plates 25 direct the airflow to the front and lower, blowing air onto the position of the cutting blade 8 that is about to be cut, blowing away the debris at that position, and preventing the debris from affecting the cutting, thereby causing damage to the cutting blade 8 and uneven cutting edges of the sheet.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
