Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, and particularly relates to a metal sheet processing and cutting device. Background Art

[0002] A metal sheet is a sheet based on a metal material. The sheet has the advantages of being convenient to pick up and place, and having a simple processing technology. Usually, the metal sheet is processed into a target component through processing technologies such as welding, cutting, stamping, and bending. Most target components need to go through two or more of the above various processes. Since the size of the metal plate is large, when processing the metal plate, the most commonly used and frequently used process is cutting, and a cutting device is required to cooperate to complete it.

[0003] After retrieval, the patent number CN111922408B discloses a metal sheet processing and cutting device, which includes a support frame. A support plate is horizontally fixed on the support frame. A push plate vertically penetrates through a strip-shaped through hole. One end of the push plate is fixedly connected to a clamping mechanism, and the other end of the push plate is fixed on a conveyor belt. A stepping mechanism for driving a runner I stepping mechanism is provided on the support frame. A cutting mechanism for cutting the metal plate is provided on the support frame. A lifting mechanism for driving the cutting mechanism to move vertically is provided on the support frame. The sheet metal cutting device for metal product processing cuts the metal plate through the provided cutting mechanism. The provided stepping mechanism can drive the clamping mechanism to drive the metal plate to perform horizontal equidistant stepping movement. The lifting mechanism drives the blade in the cutting mechanism to reciprocate vertically up and down, achieving the effect of automatic equidistant cutting of the metal plate.

[0004] The device has the following deficiencies in the specific use process: Cutting is carried out through a cutting blade. Since the cutting blade is also made of metal, only the strength and stiffness are greater than the metal sheet to be cut. There is wear during long-term use, and the cutting blade is jerky, affecting the cutting efficiency. The cutting blade needs to be replaced, and the operation is cumbersome. For a coiled metal sheet, due to the bending deformation of the metal sheet, directly cutting it will cause deviation in the cutting size, affecting the subsequent reprocessing of the cut metal sheet, and even causing the processed metal sheet to be scrapped. The coiled metal plate is bent and deformed and has a certain elasticity, and the device cannot fix it well, resulting in the probability of the metal plate moving during the cutting process, affecting the cutting efficiency. Therefore, a new type of metal sheet processing and cutting device can be adopted to solve the deficiencies of the prior art. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-2 , a metal sheet processing and cutting device, including a support frame 1, a bracket 2 is fixedly installed on the support frame 1, a cover body 4 is slidably installed on the bracket 2, and a plurality of pressure rollers 6 are rotatably installed on both the support frame 1 and the cover body 4, and a linkage mechanism is installed between two adjacent pressure rollers 6; The above points worthy of attention are: The linkage mechanism includes a first linkage gear 12 and a second linkage gear. A second linkage gear is fixedly installed on each pressure roller 6 rotatably installed on the support frame 1, and a plurality of first linkage gears 12 are rotatably installed on the support frame 1, and each first linkage gear 12 meshes with two adjacent second linkage gears; The first motor 9 rotates counterclockwise to drive the outermost pressure roller 6 fixedly connected thereto to rotate counterclockwise. The rotation of the pressure roller 6 drives the second linkage gear to rotate counterclockwise, thereby driving the first linkage gear 12 meshing therewith to rotate clockwise. The clockwise rotation of the first linkage gear 12 drives another second linkage gear meshing therewith to rotate clockwise, and so on, to drive all the pressure rollers 6 installed on the support 1 to rotate counterclockwise at the same time; Pass the metal plate through between the two rows of pressure rollers 6, and the metal plate can be leveled. The flat metal plate has more accurate control of dimensions, which can greatly reduce the probability of metal plate cutting errors caused by dimensional deviations and improve the qualified rate of the cut metal plate dimensions.

[0023] Refer to Figures 1-4, a motor 9 is fixedly installed on the support frame 1, and a fixed connection is provided between the driving end of the motor 9 and one of the pressure rollers 6. A fixed disk 3 is fixedly installed on the support 2, and a cylinder 13 is fixedly installed on the fixed disk 3. A fixed connection is provided between the cylinder 13 and the cover body 4.

A limiting mechanism matched with the pressure roller 6 is installed on each of the two slide plates 11; The cylinder 13 pushes the cover body 4 to move. During the moving process, the side plate 5 will be received into the storage groove, and the cover body 4 will press against the slide plate 11 to make the slide plate 11 move; The cylinder 13 changes the distance between the two rows of pressure rollers 6, so as to press and flatten metal plates of different thicknesses, expanding the scope of application. At the same time, the flatness of the flattening can also be adjusted, with stronger functionality.

[0024] The following points are worthy of attention: The restoring mechanism includes a chute, a slider and a return spring 18. Two sliders are fixedly installed on the slide plate 11. Two chutes matched with the corresponding sliders are provided on the side plate 5. A return spring 18 is fixedly installed between each of the two sliders and the corresponding chute; When the cover body 4 moves downward to drive the slide plate 11 to move, the slider will move in the chute along with the slide plate 11. When the cover body 4 moves upward, the return spring 18 will push the slider upward to reset the slide plate 11 to its original height; The functions of the slider and the chute are to reduce the friction force, make the slide plate 11 slide more smoothly on the side plate 5, and at the same time avoid direct contact between the slide plate 11 and the side plate 5, which can effectively reduce the wear of the slide plate 11 and extend the service life of the slide plate 11.

[0025] The limiting mechanism includes an electric push rod 15, a mounting plate 16 and a pressure wheel 17. Two electric push rods 15 are fixedly installed on each of the two slide plates 11. A mounting plate 16 is fixedly installed on the two electric push rods 15 fixed on the same slide plate 11. A plurality of pressure wheels 17 are rotatably installed on the mounting plate 16; The electric push rod 15 will adjust the distance between the two mounting plates 16 according to the width of the metal plate, so that the pressure wheels 17 on the two mounting plates 16 clamp and fix the metal plate. Combined with the fixation of the pressure roller 6, it can prevent the metal plate from sliding left and right between the two rows of pressure rollers 6 and improve the stability of the metal plate during the cutting process.

[0026] A plurality of telescopic rods are fixedly installed on the slide plate 11, and each telescopic rod is fixedly connected to the mounting plate 16; The function of the telescopic rod is to support the mounting plate 16, which can, to a certain extent, share the gravity of the mounting plate 16 and the pressing wheel 17 borne by the electric push rod 15, protect the electric push rod 15, and effectively extend the service life of the electric push rod 15.

[0027] Refer to Figures 1-2 、 Figures 7-10 , a cutting table 7 is fixedly installed on the support frame 1, two support rods 14 are fixedly installed on the cutting table 7, a guide rail 26 is fixedly installed on the two support rods 14 together, a sliding sleeve 29 is slidably installed on the guide rail 26, a driving mechanism is installed between the sliding sleeve 29 and the guide rail 26, a fixing plate 33 is fixedly installed on the sliding sleeve 29, and a high-pressure cutting water gun 30 is fixedly installed at the bottom of the fixing plate 33; The guide rail 26 is designed in an I shape, which has high stability, and the sliding stability of the sliding sleeve 29 on the guide rail 26 is higher.

[0028] The above points worthy of attention are: The driving mechanism includes a second motor 31, a transmission gear 32 and a rack 25. The rack 25 is fixedly installed on the guide rail 26, the second motor 31 is fixedly installed in the sliding sleeve 29, and a transmission gear 32 meshing with the rack 25 is fixedly installed on the driving end of the second motor 31; The second motor 31 drives the transmission gear 32 on its driving end to rotate. Under the action of the rack 25, the transmission gear 32 rotates to drive the sliding sleeve 29 to move on the guide rail 26, achieving the purpose of cutting; The second motor 31 is a bidirectional servo motor, which can rotate in both directions, so as to achieve the purpose of driving the high-pressure cutting water gun 30 to reciprocate and cut.

[0029] Refer to Figures 1-2 、 Figures 5-6 , two shaft rods 24 are rotatably installed on the support frame 1, a roller is fixedly installed on each of the two shaft rods 24, a crawler 8 is sleeved between the two rollers together, and a linkage mechanism is installed between the first motor 9 and one of the shaft rods 24; The above points worthy of attention are the following two points: A baffle 28 is fixedly installed on the cutting table 7. The baffle 28 is in a square shape with a hole in the middle. Water blocking cloths 34 are fixedly installed in two through holes on both sides of the baffle 28; Two water discharge holes 27 are formed in the cutting table 7. The two water discharge holes 27 are respectively located on both sides of the baffle 28. The blocked water can be discharged through the water discharge holes 27. A collection box is placed below the water discharge holes 27 to collect the water, which can avoid wasting water resources.

[0030] The baffle 28 is provided to block the water splashed from the high-pressure cutting water gun 30 when it contacts the metal plate, preventing the water from splashing everywhere, ensuring a clean and dry operating environment. At the same time, the water blocking cloth 34 is used to buffer the splashed water, preventing the splashed water from contacting the baffle 28 and splashing again, and can better block the water.

[0031] The linkage mechanism includes a fixed block 19, a rotating shaft 20, a first helical gear 21, a second helical gear 22, and a third helical gear 23. Two fixed blocks 19 are fixedly installed on the support frame 1. A rotating shaft 20 is rotatably installed on the two fixed blocks 19 together. A second helical gear 22 is fixedly installed at both ends of the rotating shaft 20. A third helical gear 23 meshing with one of the second helical gears 22 is fixedly installed on the shaft rod 24. A first helical gear 21 meshing with the other second helical gear 22 is fixedly installed on the driving end of the first motor 9. When the first motor 9 rotates counterclockwise, it drives the first helical gear 21 to rotate counterclockwise, thereby driving the second helical gear 22 meshing with the first helical gear 21 to rotate clockwise (the rotation direction of the second helical gear 22 is observed from right to left in Figure 5 this figure). The other second helical gear 22 drives the third helical gear 23 meshing with it to rotate counterclockwise, thereby realizing the counterclockwise rotation of the track 8. The cut metal plate can be transported away through the track 8. Using a single first motor 9 to drive the pressure roller 6 and the track 8 to rotate reduces the manufacturing cost and also reduces the power consumption during operation, making it more economical and affordable.

[0032] The specific operation process of this device is as follows: When the first motor 9 rotates counterclockwise, it drives the outermost pressure roller 6 fixedly connected to it to rotate counterclockwise. The rotation of the pressure roller 6 drives the second linkage gear to rotate counterclockwise, thereby driving the first linkage gear 12 meshing with it to rotate clockwise. The clockwise rotation of the first linkage gear 12 drives the other second linkage gear meshing with it to rotate clockwise. By analogy, all the pressure rollers 6 installed on the support frame 1 can be driven to rotate counterclockwise at the same time, and the metal plate is passed through between the two rows of pressure rollers 6. The cylinder 13 pushes the cover body 4 to move. During the movement, the side plate 5 will be received into the receiving groove, and the cover body 4 will press against the slide plate 11 to make the slide plate 11 move. The cylinder 13 changes the distance between the two rows of pressure rollers 6, so as to press and flatten metal plates of different thicknesses. The electric push rod 15 will adjust the distance between the two mounting plates 16 according to the width of the metal plate, so that the pressure wheels 17 on the two mounting plates 16 clamp and fix the metal plate. Cooperating with the fixation of the pressure rollers 6, it can prevent the metal plate from sliding left and right between the two rows of pressure rollers 6, improving the stability of the metal plate during the cutting process. The second motor 31 drives the transmission gear 32 on its driving end to rotate. Under the action of the rack 25, the transmission gear 32 rotates to drive the sliding sleeve 29 to move on the guide rail 26, achieving the purpose of cutting. The baffle 28 and the water blocking cloth 34 can prevent water from splashing. The blocked water can be discharged through the water drain hole 27. A collection box is placed below the water drain hole 27 to collect the water, which can avoid wasting water resources. The first motor 9 rotates counterclockwise to drive the first helical gear 21 to rotate counterclockwise, thereby driving the second helical gear 22 meshing with the first helical gear 21 to rotate clockwise (the rotation direction of the second helical gear 22 is observed from right to left in Figure 5 the figure). Another second helical gear 22 drives the third helical gear 23 meshing with it to rotate counterclockwise, thereby realizing the counterclockwise rotation of the crawler 8. The cut metal plate can be transported away through the crawler 8.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
