[0027] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0028] Refer to Figures 1 to 9As shown in the figure, a cutting device for a new type of shaped plate includes a front-end pre-cutting mechanism 1, a photoelectric detection mechanism 2, a rear-end shearing mechanism 3, and multiple groups of operating mechanisms. The front-end pre-cutting mechanism 1 is arranged at the front end of the entire cutting device. Multiple groups of the operating mechanisms are sequentially arranged behind the front-end pre-cutting mechanism 1. The photoelectric detection mechanism 2 and the rear-end shearing mechanism 3 are sequentially arranged behind the multiple groups of the operating mechanisms. Thus, the steel coil 4 starts to perform the first process from the front-end pre-cutting mechanism 1, then undergoes process processing according to multiple groups of the operating mechanisms, and finally is sheared by the rear-end shearing mechanism 3 after being detected by the photoelectric detection mechanism 2 to complete the processing.

[0029] Reference Figure 3 As shown in the figure, the front-end pre-cutting mechanism 1 includes a pre-cutting component 10 and an oil cylinder 19 arranged above the pre-cutting component 10. The oil cylinder 19 applies pressure to enable the pre-cutting component 10 to process the steel coil 4. Reference Figure 4 And Figure 5 As shown in the figure, the pre-cutting component 10 includes a top plate 11 connected to the oil cylinder 19, a cutter locking plate 13 connected below the top plate 11, a cutter guide sleeve 14 and a guide sleeve fixing plate 15 sequentially arranged below the cutter locking plate 13, and a bottom cutter fixing plate 17 and a bottom plate 18 arranged below the guide sleeve fixing plate 15. A cutter 131 is arranged on the cutter locking plate 13, a bottom cutter 16 is arranged on the bottom cutter fixing plate 17, and multiple guide posts 12 are arranged on the top plate 11. When the oil cylinder 19 presses downward, the oil cylinder 19 drives the top plate 11 to drive the cutter 131 to move downward to the bottom cutter 16.

[0030] Reference Figure 3 And Figure 4As shown, specifically, a first connection hole 111 is respectively formed at four corners of the top plate 11. The top plate 11 is connected to the oil cylinder 19 through the first connection hole 111, so that the top plate 11 can move up and down with the movement of the oil cylinder 19. A connecting plate 112 is arranged between the top plate 11 and the cutter locking plate 13. The connecting plate 112 is connected to the top plate 11 upward and the cutter locking plate 13 downward. The cutter locking plate 13 and the connecting plate 112 can move up and down with the top plate 11. A cutter groove is formed in the middle of the cutter locking plate 13. The cutter 131 is inserted into the cutter groove and fixed. The cutter 131 moves up and down with the cutter locking plate 13. In this embodiment, the cutting edge of the cutter 131 passes through the cutter groove and is arranged on the side away from the top plate 11, and the handle of the cutter 131 is fixed on the side of the cutter groove close to the top plate 11. According to the cutting requirements of each steel coil 4, a plurality of cutters 131 are provided, and the number of the cutter grooves is the same as that of the cutters 131. In this embodiment, two cutters 131 are provided, and the cutting edges of the cutters 131 are inclined, and the sharp corners of the downward inclined ends of the two cutting edges of the cutters 131 are close to each other.

[0031] Reference Figure 4 As shown, specifically, a plurality of second connection holes 181 are formed in the bottom plate 18. The bottom plate 18 connects the pre-cutting assembly 10 to the fixing member at the lower end of the front pre-cutting mechanism 1 through the second connection holes 181. The bottom plate 18 is further provided with a plurality of third connection holes 182. The bottom cutter fixing plate 17 is provided with a plurality of fourth connection holes 171 corresponding to the third connection holes 182. A locking member connects the third connection holes 182 and the fourth connection holes 171 to connect the bottom plate 18 and the bottom cutter fixing plate 17. The bottom cutter 16 is fixedly connected to the bottom cutter fixing plate 17. The number of the bottom cutters 16 is the same as that of the cutters 131, and each bottom cutter 16 corresponds to one cutter 131.

[0032] Reference Figure 3 and Figure 4As shown, specifically, a first through hole is respectively formed at each of the four corners of the top plate 11, and each of the first through holes is disposed on one side of each of the first connection holes 111. In this embodiment, a guide post 12 is inserted into each of the first through holes. Second through holes 151 are respectively formed at the four corners of the guide sleeve fixing plate 15, and each of the second through holes 151 corresponds to one of the first through holes. When the top plate 11 drives the guide posts 12 and the cutting knife 131 to move downward, each of the guide posts 12 can be movably inserted into each of the second through holes 151. A fixing groove is formed in the middle of the guide sleeve fixing plate 15, and the cutting knife guide sleeve 14 is fixedly disposed in the fixing groove. The number of the fixing grooves is the same as the number of the cutting knives 131, and the number of the cutting knife guide sleeves 14 is the same as the number of the cutting knives 131, and each of the cutting knife guide sleeves 14 corresponds to one of the cutting knives 131. A cutting knife 131 groove is formed in each of the cutting knife guide sleeves 14. When the cutting knife 131 moves downward, the cutting knife 131 is inserted into the cutting knife 131 groove, can pass through to one side of the bottom surface of the guide sleeve fixing plate 15, and can abut against the bottom knife 16.

[0033] After the leveling and punching parts of the steel coil 4 are processed and reach the length to be sheared, the steel coil 4 enters between the guide sleeve fixing plate 15 and the bottom knife 16 of the front-end pre-cutting mechanism 1. The front-end pre-cutting mechanism 1 is adjusted to the rib-forming position, the oil cylinder 19 applies pressure, and the top plate 11 drives the cutting knife locking plate 13 to drive the cutting knife 131 to move downward and pass through the cutting knife guide sleeve 14. The cutting knife 131 cuts off the part to be rib-formed until it abuts against the bottom knife 16. The cutting knife 131 is lifted, and the steel coil 4 continues to move forward to complete the forming movement of C-shaped or Z-shaped or U-shaped. After the steel coil 4 is processed by multiple groups of the operating mechanisms, such as rib-forming, outer small-edge forming, inner small-edge forming, waist height and bottom width forming, etc., it enters the photoelectric detection mechanism 2.

[0034] The photoelectric detection mechanism 2 includes a vertical plate 21, a horizontal plate 22 disposed on the vertical plate 21, and a detection member 23 disposed at one end of the horizontal plate 22. The other end of the horizontal plate 22 is connected to the vertical plate 21, and the horizontal plate 22 is fixed in the middle of the vertical plate 21. The vertical plate 21 is fixed to the equipment. Specifically, referring to Figure 6 and Figure 7 As shown, first detection points 231 and second detection points 232 are respectively disposed at both ends of the detection member 23. The first detection point 231 is disposed at the end of the detection member 23 close to the horizontal plate 22, and the speed is reduced after the first detection point 231 detects the cut; the second detection point 232 is disposed at the end of the detection member 23 far from the horizontal plate 22, and the distance is determined after the second detection point 232 detects the cut, so that the blade 31 of the subsequent rear-end shearing mechanism 3 can accurately cut into the cut.

[0035] The photoelectric detection mechanism 2 is adjusted to the position where the steel coil 4 is pre-cut by the front-end pre-cutting mechanism 1. Before the formed steel coil 4 moves to the photoelectric detection mechanism 2, after the first detection point 231 detects the cut, the steel coil 4 decelerates. At the same time, the second detection point 232 performs detection. The second detection point 232 plays a positioning role and ensures that the shearing of the rear-end shearing mechanism 3 can accurately shear from the cut pre-sheared by the front-end pre-cutting mechanism 1. The rear-end shearing mechanism 3 includes two spaced-apart columns 32, a chip dropping seat 34 and a movable assembly 30 disposed between the two columns 32, and a blade 31 disposed on the movable assembly 30. The chip dropping seat 34 is disposed at the lower end, and the movable assembly 30 is disposed at the upper end. The movable assembly 30 moves to drive the blade 31 to move downward to shear the steel coil 4, and the waste chips of the sheared steel coil 4 fall from the chip dropping seat 34 to be collected. Refer to Figure 8 and Figure 9 As shown in the figure, specifically, the lower front ends of the two columns 32 are connected with a front frame 33. The front frame 33 is provided with a window 331. A roller 35 is fixedly disposed on the front end surface of the front frame 33. The roller 35 is disposed below the window 331. The upper surface of the roller 35 is flush with the lower end surface of the window 331 and flush with the upper surface of the chip dropping seat 34. The chip dropping seat 34 is provided with a chip dropping groove 341 downward. The steel coil 4 is fed from the roller 35 into the window 331 to the upper surface of the chip dropping seat 34. The movable assembly 30 drives the blade 31 to shear downward the steel coil 4 located above the chip dropping seat 34, and the waste chips fall into the chip dropping groove 341 to be collected. In this embodiment, the chip dropping groove 341 can be set as a bottomed structure or a through structure. More reasonably, the chip dropping groove 341 is set as a through structure, and a bag can be sleeved below the through structure to collect the waste chips. Specifically, the movable assembly 30 includes two racks 39 respectively disposed on the front surfaces of the two columns 32, a bushing seat 38 disposed on one side where the two columns 32 are close to each other, a connecting shaft 36 disposed on the front end surfaces of the two columns 32 and passing through the two bushing seats 38, and gears 37 disposed at both ends of the connecting shaft 36. The two gears 37 are respectively disposed on the sides where the two bushing seats 38 are away from each other and are engaged with the racks 39. A blade handle 311 is connected between the two bushing seats 38, and the blade 31 is connected below the blade handle 311. Cylinders are respectively disposed above the two bushing seats 38. The cylinders work to drive the bushing seats 38 to move, and drive the two gears 37 to move on the two racks 39 simultaneously through the connecting shaft 36. At the same time, the blade handle 311 drives the blade 31 to move up and down with the bushing seats 38.

[0036] Upon receiving the detection signal from the second detection point 232, the rear-end shearing mechanism 3 allows the steel coil 4 to continue moving. After the pre-cut notch made by the front-end pre-cutting mechanism moves below the blade 31, it stops. The movable assembly 30 drives the blade handle 311 to drive the blade 31 to move downward, and the blade 31 cuts along the pre-cut notch to complete the cutting of various special-shaped plates.

[0037] A control method for a cutting device for new-shaped plates, comprising: S1. The front-end pre-cutting mechanism 1 performs pre-cutting on the steel coil 4, and a plurality of pre-cut notches are formed between each same distance segment of the steel coil 4. S2. The photoelectric detection mechanism 2 detects the pre-cut notches on the steel coil 4 and determines whether the distance between each two groups of pre-cut notches is the same. If the same, it proceeds to S3; otherwise, it is picked out. S3. The rear-end shearing mechanism 3 shears the pre-cut notches on the steel coil 4, and the steel coil 4 forms the required length.

[0038] More precisely, in this embodiment, a control method for a cutting device for new-shaped plates is adopted to perform a shearing operation on the steel coil 4 according to the length that the steel coil 4 needs to be sheared.

[0039] S1. The front-end pre-cutting mechanism 1 performs pre-cutting on the steel coil 4, and a plurality of pre-cut notches are formed between each same distance segment of the steel coil 4.

[0040] S11. In the equipment, the steel coil 4 needs to be pre-leveled so that the steel coil 4 can obtain accurate and precise dimensions in subsequent processing. After the steel coil 4 is leveled, punching processing is performed on the steel coil 4 according to the dimensional requirements.

[0041] S12. When the steel coil 4 reaches the length that needs to be sheared, the front-end pre-cutting mechanism 1 is adjusted to the position of forming ribs. The oil cylinder 19 applies pressure to the pre-cutting assembly 10, and the cutting knife 131 cuts off the rib-forming part. The cutting knife 131 moves upward and leaves the steel coil 4. The steel coil 4 is formed with pre-cut notches and continues to move forward.

[0042] S13. According to the dimensional requirements, the next punching and rib-forming positions are formed on the steel coil 4 at a specified distance, and S11 and S12 are continuously executed.

[0043] S2. The photoelectric detection mechanism 2 detects the pre-cut notches on the steel coil 4 and determines whether the distance between each two groups of pre-cut notches is the same. If the same, it proceeds to S3; otherwise, it is picked out.

[0044] S21. When the steel coil 4 with formed pre-cut notches moves to before the photoelectric detection mechanism 2, the first detection point 231 detects the pre-cut notch, and the steel coil 4 with pre-cut notches decelerates. The second detection point 232 positions the steel coil 4 and executes S3.

[0045] S22. Before the formed steel coil 4 with a pre-cut moves to the photoelectric detection mechanism 2, if the first detection point 231 does not detect the pre-cut, the steel coil 4 decelerates, and each process of the cutting device decelerates and pauses, and the reason is detected manually.

[0046] S23. When the reason is found and the size is qualified, the steel coil 4 is continuously fed into the photoelectric detection mechanism 2, and S21 is executed.

[0047] S24. When the reason is found and the size is unqualified, the unqualified part of the steel coil 4 is manually cut and picked out, and the steel coil 4 continues to move forward, and S21, S22 and S23 are executed.

[0048] S3. The rear-end shearing mechanism 3 shears the pre-cut on the steel coil 4, and the steel coil 4 forms the required length.

[0049] When the rear-end shearing mechanism 3 receives the positioning signal of the second detection point 232, the steel coil 4 continues to move forward. When the pre-cut moves to the blade 31 of the rear-end shearing mechanism 3, it stops. The blade 31 moves downward and shears downward along the pre-cut, and cuts the steel coil 4, so that the cutting process of various special-shaped plates can be completed.

[0050] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
