Description

Technical Field

[0001] The invention relates to the technical field of C-shaped steel cutting, in particular to a cutting device for producing and processing C-shaped steel. Background Art

[0002] C-shaped steel is made by cold bending of hot rolled plate. It has the characteristics of thin wall, light weight, excellent cross-sectional performance and high strength. It is mainly used for equipment frames and brackets.

[0003] After the C-shaped steel is manufactured, in order to ensure that the ends are neat, the ends of the C-shaped steel need to be cut. The existing C-shaped steel cutting machine mainly uses a rotary cutter to cut from top to bottom. Due to the large width of the C-shaped steel, as the traditional cutting goes deeper, the contact area between the cutter and the C-shaped steel increases, which increases the friction between the cutter and the C-shaped steel. The increased friction can easily cause damage to the cutter and an uneven cross-section of the C-shaped steel.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cutting device for C-shaped steel production and processing is proposed. Summary of the invention

[0009] Furthermore, a plurality of support rods are installed on one side of the first annular plate facing the second annular plate.

An annular groove is formed on the side of the second annular plate away from the arc-shaped grooves. A clamping member is rotatably connected in the annular groove.

[0010] Furthermore, the clamping member includes an annular cylinder disposed in the annular groove. A sealing plate is slidably connected in the annular cylinder.

[0016] The present invention provides a cutting device for C-shaped steel production and processing, having the following beneficial effects: This cutting device for C-shaped steel production and processing, through the mutual cooperation between multiple components, can not only...

[0017] 1. In the present invention, multiple circularly arranged saw blades are installed on a cylinder. After the C-shaped steel enters between the multiple saw blades, the driving motor is started to drive the multiple saw blades to cut from the outer surface of the C-shaped steel. As the truncation progresses, the rotation block is abutted by the abutting block, causing the saw blades to gradually converge towards the center of the C-shaped steel, completing the circular cutting of the C-shaped steel. Since the middle of the C-shaped steel is hollow, the contact between the saw blades and the C-shaped steel can be reduced during the truncation process, reducing the probability of damage to the saw blades and the vibration generated during the cutting process, and avoiding uneven cut marks.

[0018] 2. In the present invention, an extrusion structure composed of a sealing cylinder, a piston, a holding rod, and a clamping block is installed on the side of the second annular plate away from the first annular plate. The C-shaped steel is clamped by the extrusion structure. As the truncation continues, due to the rotational speed difference between the first annular plate and the second annular plate, the inclined block moves into the annular groove, increasing the space between the sealing plate and the annular groove. The air in the sealing cylinder enters the annular groove through the connecting pipe, resulting in a decrease in the extrusion inside the sealing cylinder, pushing the piston, the holding rod, and the clamping block towards the center of the second annular plate, that is, increasing the clamping force of the extrusion structure on the C-shaped steel and reducing the vibration generated after the contact between the saw blades and the C-shaped steel increases.

[0019] 3. In the present invention, a negative pressure fan is installed on the annular surface of the connecting cylinder. The rotation of the connecting cylinder forms a negative pressure to collect the debris generated during the truncation of the C-shaped steel, avoiding the scattering of the debris. And when the cutting stops, the debris falls into the collection box due to gravity, making the whole debris collection process more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a cutting device for C-shaped steel production and processing, including a first annular plate 19. A second annular plate 8 is arranged on one side of the first annular plate 19. A ring 21 is installed on the side of the first annular plate 19 facing the second annular plate 8. A plurality of fixed rods 23 are installed on the side of the ring 21 away from the first annular plate 19. A plurality of rotating blocks 22 are rotatably connected to the circumferential surface of the fixed rods 23. A saw blade 18 is installed on the side of the rotating block 22 facing the inside of the ring 21. A plurality of supporting blocks 24 are installed on the inner circumferential surface of the second annular plate 8. The rotating block 22 is in contact with the supporting block 24. A driving motor 1 is arranged on the side of the first annular plate 19 away from the second annular plate 8. A connecting cylinder 2 is installed at the output end of the driving motor 1. One end of the connecting cylinder 2 away from the driving motor 1 is connected to the first annular plate 19.

[0023] The driving motor 1 drives the first annular plate 19 to rotate through the connecting cylinder 2. After the first annular plate 19 rotates, it drives a plurality of rotating blocks 22 to rotate through the ring 21. When the rotating block 22 rotates, it can drive the saw blade 18 to rotate to cut the C-shaped steel.

[0024] A first gear ring 6 is installed on the circumferential surface of the first annular plate 19. A second gear ring 7 is installed on the circumferential surface of the second annular plate 8. The first gear ring 6 is smaller than the second gear ring 7. A first gear 11 is meshed with the circumferential surface of the first gear ring 6. A second gear 12 is meshed with the circumferential surface of the second gear ring 7. A connecting rod 13 is installed between the first gear 11 and the second gear 12.

[0025] After the first gear ring 6 rotates, it drives the second gear ring 7 to rotate through the transmission structure composed of the first gear 11, the second gear 12 and the connecting rod 13. Since the first gear ring 6 is smaller than the second gear ring 7 and the first gear 11 is larger than the second gear 12, the rotational speed of the first gear ring 6 is greater than that of the second gear ring 7. That is, after the first gear ring 6 rotates one circle, the second gear ring 7 does not rotate one circle. Since the rotating block 22 is in contact with the abutting block 24, when the first gear ring 6 rotates one circle while the second gear ring 7 does not rotate one circle, the abutting block 24 and the rotating block 22 cannot maintain the relative position of the previous circle, but gradually move toward the side of the rotating block 22 away from the fixed rod 23, thereby squeezing the rotating block 22, making the saw blade 18 installed on the rotating block 22 closer to the center of the first annular plate 19, thereby completing the truncation of the C-shaped steel. And since the saw blade 18 starts cutting from the edge of the C-shaped steel and gradually moves toward the center of the C-shaped steel, and the center of the C-shaped steel is hollow, during the process of cutting the C-shaped steel by the saw blade 18, the friction between the saw blade 18 and the C-shaped steel is reduced, thereby reducing the probability of damage to the saw blade 18.

[0026] A plurality of support rods 20 are installed on the side of the first annular plate 19 facing the second annular plate 8. A plurality of arc-shaped grooves 26 are formed on the side of the second annular plate 8 facing the first annular plate 19. The support rods 20 are inserted into the arc-shaped grooves 26. An annular groove is formed on the side of the second annular plate 8 away from the arc-shaped grooves 26. An annular cylinder 9 is rotatably connected in the annular groove. A sealing plate 27 is slidably connected in the annular cylinder 9. A plurality of inclined blocks 25 are installed on the side of the sealing plate 27 facing the annular groove. The inclined blocks 25 are in contact with the support rods 20. A plurality of sealing cylinders 10 are installed on the side of the annular cylinder 9 facing the outside of the annular groove. A piston 29 is slidably connected in the sealing cylinder 10. A abutting rod 30 is installed on the side of the piston 29 facing the center of the second annular plate 8. The side of the abutting rod 30 away from the piston 29 penetrates through the sealing cylinder 10 and a clamping block 31 is installed. A connecting pipe 28 is communicated between the space on the side of the piston 29 facing the abutting rod 30 and the space in the annular groove.

[0027] The first annular plate 19 drives the support rods 20 to rotate, and the second annular plate 8 drives the inclined blocks 25 to rotate. Since the rotational speed of the first annular plate 19 is greater than that of the second annular plate 8, the support rods 20 gradually squeeze the inclined blocks 25 during rotation, causing the inclined blocks 25 to move into the annular groove, thereby squeezing the sealing plate 27 to move toward the outside of the annular groove. The space on the side of the sealing plate 27 facing the inside of the annular groove increases, and air in the sealing cylinder 10 can be sucked in through the connecting pipe 28. The air in the sealing cylinder 10 decreases and the negative pressure increases. In order to balance the air pressure, the squeezing structure composed of the piston 29, the abutting rod 30 and the clamping block 31 moves toward the center of the second annular plate 8, thereby realizing the clamping of the C-shaped steel. And as the truncation of the C-shaped steel proceeds, the rotation of the first annular plate 19 increases the squeezing of the inclined blocks 25 by the support rods 20, and the clamping force of the squeezing structure on the C-shaped steel increases.

[0028] A through hole is further formed at one end of the annular cylinder 9 facing the outside of the annular groove. The through hole is used to balance the air pressure inside the annular cylinder 9, and a reset rod 5 is inserted into the through hole. The reset rod 5 is in contact with the sealing plate 27. After the cutting is completed, the reset rod 5 is squeezed to balance the air pressure on the side of the sealing plate 27 facing the inside of the annular groove, which facilitates the removal of the cut C-shaped steel from between the multiple extrusion structures. At the same time, the components on the first annular plate 19 and the components on the second annular plate 8 are restored to their original positions.

[0029] A rectangular groove 17 is formed on the annular surface of the connecting cylinder 2. A conical cover 3 is rotatably connected to the annular surface of the rectangular groove 17 of the connecting cylinder 2. A negative pressure fan 16 installed on the annular surface of the connecting cylinder 2 is arranged inside the conical cover 3. A filter screen 15 is installed at the end of the conical cover 3. The filter screen 15 is rotatably connected to the connecting cylinder 2. A notch 14 is formed on the lower side of the annular surface of the conical cover 3, and a collection box is installed at the notch 14.

[0030] The rotation of the connecting cylinder 2 drives the rotation of the negative pressure fan 16. The rotation of the negative pressure fan 16 forms a negative pressure to collect the debris generated during the cutting of the C-shaped steel. Subsequently, the debris is gradually collected at the filter screen 15. When the cutting stops, the debris will gradually move to the lowest point at the bottom of the conical cover 3 due to its own gravity and finally fall into the collection box installed on the lower side of the annular surface of the conical cover 3. The cut part of the C-shaped steel will also fall into the collection box from the rectangular groove 17 formed on the annular surface of the connecting cylinder 2.

[0031] Finally, in order to ensure the sealing between the first annular plate 19 and the second annular plate 8, a sealing cover 4 is arranged on the annular surfaces of the first gear ring 6 and the second gear ring 7. The conical cover 3 is connected to the sealing cover 4. With the sealing of the sealing cover 4, the air flow can only enter through the center of the second annular plate 8 and flow out from the filter screen 15 at the end of the conical cover 3, ensuring the collection of debris during the cutting of the C-shaped steel.

[0032] In summary, for the C-shaped steel production and processing cutting equipment, during use, first start the driving motor 1 to drive the rotation of the connecting cylinder 2. The rotation of the connecting cylinder 2 drives the rotation of the first annular plate 19 and the negative pressure fan 16. The rotation of the first annular plate 19 drives the rotation of the cutting structure, thereby cutting the C-shaped steel. The rotation of the negative pressure fan 16 collects the debris generated during the cutting process into the conical cover 3.

[0033] Moreover, the rotation of the first annular plate 19 drives the rotation of the second annular plate 8 through the linkage structure. The rotation of the second annular plate 8 drives the rotation of the abutting block 24. The rotational speed of the abutting block 24 is lower than that of the rotating block 22. Therefore, as the cutting progresses, the abutting block 24 gradually presses against the abutting block 24, causing the saw blade 18 mounted on the rotating block 22 to gradually deflect towards the center of the first annular plate 19, realizing the cutting of the C-shaped steel. And since the saw blade 18 starts cutting from the edge of the C-shaped steel and gradually cuts towards the center of the C-shaped steel, and the center of the C-shaped steel is hollow, during the cutting process of the saw blade 18 on the C-shaped steel, the friction between the saw blade 18 and the C-shaped steel is reduced, thereby reducing the probability of damage to the saw blade 18.

[0034] During the rotation of the first annular plate 19 and the second annular plate 8, the support rod 20 gradually presses against the inclined block 25, causing the inclined block 25 to move into the annular groove, and further pressing the sealing plate 27 to move towards the outside of the annular groove. The space on the side of the sealing plate 27 facing the inside of the annular groove increases. The air in the sealing cylinder 10 is sucked into the space between the sealing plate 27 and the annular groove through the connecting pipe 28. The air in the sealing cylinder 10 decreases, and the negative pressure increases, causing the pressing structure to move towards the center of the second annular plate 8, thereby realizing the clamping of the C-shaped steel. As the cutting of the C-shaped steel progresses, the rotation of the first annular plate 19 increases the pressing of the support rod 20 against the inclined block 25, and the clamping force of the pressing structure on the C-shaped steel increases, avoiding the increase in vibration caused by the increase in the contact between the saw blade 18 and the C-shaped steel and resulting in the shaking of the C-shaped steel.
