Description

Technical Field

[0001] This invention relates to the field of cold-rolled sheet processing technology, and more specifically, to a cold-rolled sheet bending device. Background Technology

[0002] Cold-rolled sheet bending is a mainstream forming process in the sheet metal processing industry. Leveraging the high surface smoothness, uniform strength, and good plasticity of cold-rolled sheets, it is widely used in equipment housings, cabinets, and precision structural components. For equipment cover plates, all four sides of the cold-rolled sheet need to be bent to create flanges. Currently, the bending operation for cover plates typically requires workers to hold the cover plate, align it with the bending equipment, and then place all four sides into the bending equipment one by one for bending. For mass production, this is not only cumbersome but also inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide a cold-rolled sheet bending processing device that can continuously convey and bend cold-rolled sheets multiple times, completing the folding operation of the four sides of the cold-rolled sheet, and enabling batch continuous processing to improve processing efficiency.

[0004] This invention is achieved through the following technical solution: a cold-rolled steel sheet bending processing device, comprising: A chain conveyor includes a first frame and a drive chain, on which multiple sets of limiting blocks are spaced apart to define the position of the cold-rolled sheet; Two sets of first bending mechanisms are symmetrically distributed on opposite sides of the chain conveyor, used to simultaneously bend the two opposite sides of the cold-rolled sheet; A roller conveyor, located on one side of the end of a chain conveyor, includes a second frame and multiple conveying rollers, wherein the length direction of the second frame is perpendicular to the length direction of the first frame; Two sets of second bending mechanisms, one set of which is located on one side of the beginning of the roller conveyor and directly opposite the exit end of the chain conveyor, and the other set of which is located on one side of the end of the roller conveyor. The height of the roller conveyor is lower than that of the chain conveyor. The bottom of the roller conveyor is provided with two sets of guide components, which can respectively guide the cold-rolled plate into two sets of second bending mechanisms to bend the corresponding sides.

[0005] Furthermore, the guide component includes a base, and lifting cylinders are provided on both sides of the base. A support frame is provided on the piston rod of the lifting cylinder, and multiple guide strips are provided between the support frames on both sides. Each guide strip is located in the gap between the conveying rollers on the roller conveyor and can extend upward to the upper part of the conveying roller.

[0006] Furthermore, the height of the support frame on the side closer to the second bending mechanism is lower than the height of the support frame on the side farther away from the second bending mechanism; the guide bar is inclined and has pulleys spaced apart along its length.

[0007] Furthermore, both the first bending mechanism and the second bending mechanism include a base, a support plate, a pressing member, and a bending member. The base of the first bending mechanism is fixedly mounted on the first frame, and the base of the second bending mechanism is fixedly mounted on the second frame. The support plate is mounted on the base, the pressing member is mounted on the upper part of the base and can press the cold-rolled sheet, and the bending member is mounted on the lower part of the base and can drive the edge of the cold-rolled sheet to bend.

[0008] Furthermore, the base of the first bending mechanism is horizontally arranged, while the base of the second bending mechanism is inclined and the inclination angle is consistent with the inclination angle of the corresponding guide component.

[0009] Furthermore, a correction element for preventing the cold-rolled sheet from shifting is provided between the two sets of the first bending mechanism and on each set of the second bending mechanism. The correction element includes two opposing correction strips, each having a straight section and a bent section.

[0010] Furthermore, the spacing between the two straightening strips between the two sets of the first bending mechanism is consistent with the length of the cold-rolled plate before bending, and the spacing between the two straightening strips on the second bending mechanism is consistent with the length of the cold-rolled plate after bending.

[0011] Furthermore, the end of the roller conveyor is provided with a guide frame, which extends downward at an angle and has multiple guide rollers distributed on it.

[0012] The technical solution of the present invention has at least the following advantages and beneficial effects: 1. This invention uses a chain conveyor and a roller conveyor with mutually perpendicular conveying directions. During the conveying of the cold-rolled plate by the chain conveyor, the first bending mechanism on both sides simultaneously bends the two opposite sides of the cold-rolled plate. Then, the roller conveyor changes the conveying direction of the cold-rolled plate, and the two sets of second bending mechanisms on both sides of the roller conveyor bend the remaining two sides of the cold-rolled plate in turn, thereby completing the bending process of the four sides of the cold-rolled plate.

[0013] 2. This invention configures two sets of guide components at the bottom of the roller conveyor. By using a lifting electric cylinder to drive the support frame to move upward, the support frame can drive the guide strip to extend upward to the upper part of the conveying roller, thereby guiding the cold-rolled plate into two sets of second bending mechanisms to bend the corresponding sides.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0017] The following detailed description, in conjunction with specific embodiments, further illustrates that this embodiment provides a cold-rolled sheet bending processing device, referring to... Figure 1 , Figure 2As shown, the system includes a chain conveyor 1, two sets of first bending mechanisms 2, a roller conveyor 3, and two sets of second bending mechanisms 4. The chain conveyor 1 includes a first frame 11 and a drive chain 12. Multiple sets of limiting blocks 13 for limiting the position of the cold-rolled sheet are distributed at intervals on the drive chain 12. The drive chain 12 is driven by a stepper motor to place the cold-rolled sheet between the limiting blocks 13. The stepper motor can drive the limiting blocks 13 to move forward a specified distance each time, thereby periodically conveying the cold-rolled sheet at a fixed length. The two sets of first bending mechanisms 2 are symmetrically distributed on opposite sides of the chain conveyor 1. When the cold-rolled sheet moves to the specified position, the first bending mechanisms 2 on both sides simultaneously bend the two opposite sides of the cold-rolled sheet.

[0018] Reference Figure 1 , Figure 3 As shown, the roller conveyor 3 is located on one side of the end of the chain conveyor 1, and includes a second frame 31 and multiple conveying rollers 32. The second frame 31 houses a motor assembly for driving the conveying rollers 32. The length direction of the second frame 31 is perpendicular to the length direction of the first frame 11. One set of second bending mechanisms 4 is located on one side of the beginning of the roller conveyor 3, directly opposite the outlet end of the chain conveyor 1, while another set of second bending mechanisms 4 is located on one side of the end of the roller conveyor 3. After two sides of the cold-rolled sheet are bent by the first bending mechanism 2, the cold-rolled sheet continues to move and enters the roller conveyor 3. The roller conveyor 3 changes its conveying direction for the cold-rolled sheet, and the two sets of second bending mechanisms 4 located on both sides of the roller conveyor 3 successively bend the remaining two sides of the cold-rolled sheet, thus completing the bending process of all four sides of the cold-rolled sheet.

[0019] The height of the roller conveyor 3 is lower than that of the chain conveyor 1, so that the cold-rolled sheet can fall smoothly from the chain conveyor 1 into the roller conveyor 3. The bottom of the roller conveyor 3 is provided with two sets of guide members 5, which can respectively guide the cold-rolled sheet into two sets of second bending mechanisms 4 to bend the corresponding sides.

[0020] Reference Figure 3 , Figure 4As shown, the guide component 5 includes a base 51, with lifting cylinders 52 on both sides of the base 51. Support frames 53 are mounted on the piston rods of the lifting cylinders 52, and multiple guide strips 54 are arranged between the support frames 53 on both sides. Each guide strip 54 is located in the gap between the conveying rollers 32 on the roller conveyor 3. By moving the support frames 53 upwards through the lifting cylinders 52, the support frames 53 can cause the guide strips 54 to extend upwards to the upper part of the conveying rollers 32, thereby guiding the cold-rolled sheet. It should be noted that the height of the support frames 53 on the side closer to the second bending mechanism 4 is lower than the height of the support frames 53 on the side farther from the second bending mechanism 4, so that the guide strips 54 are in an inclined state. When the guide strips 54 move upwards, they can drive the cold-rolled sheet to move to the lowest end of the guide strips 54 and enter the second bending mechanism 4. (Refer to...) Figure 5 As shown, in order to improve the smoothness of the cold-rolled sheet sliding, pulleys 541 are also distributed at intervals along the length of the guide bar 54.

[0021] Reference Figure 1 , Figure 3 As shown, a guide member 6 is provided between the two sets of first bending mechanisms 2 and on each set of second bending mechanisms 4 to prevent the cold-rolled sheet from shifting. The guide member 6 includes two oppositely arranged guide strips 61, each guide strip 61 having a straight section 611 and a bent section 612. When the cold-rolled sheet enters the area between the two guide strips 61, the guide strips 61 can limit and correct the cold-rolled sheet, thereby ensuring that the cold-rolled sheet is in the proper position during bending and preventing the bending part from shifting.

[0022] The spacing between the two straightening strips 61 between the two sets of first bending mechanisms 2 is consistent with the length of the cold-rolled plate before bending, so as to adapt to the length of the cold-rolled plate before bending; the spacing between the two straightening strips 61 on the second bending mechanism 4 is consistent with the length of the cold-rolled plate after bending, so as to adapt to the length of the cold-rolled plate after bending.

[0023] Reference Figure 2 , Figure 3 As shown, the first bending mechanism 2 and the second bending mechanism 4 have the same structure, both including a base 21, a support plate 22, a pressing member 23 and a bending member 24. The base 21 of the first bending mechanism 2 is fixedly mounted on the first frame 11, and the base 21 of the second bending mechanism 4 is fixedly mounted on the second frame 31. The support plate 22 is mounted on the base 21 and is used to support the bottom surface of the cold-rolled plate entering the base 21. The pressing member 23 is mounted on the upper part of the base 21 and can press the top surface of the cold-rolled plate entering the base 21. The bending member 24 is mounted on the lower part of the base 21 and can drive the edge of the cold-rolled plate to bend.

[0024] The difference between the first bending mechanism 2 and the second bending mechanism 4 is that the base 21 of the first bending mechanism 2 is horizontally set, while the base 21 of the second bending mechanism 4 is inclined and the inclination angle is consistent with the inclination angle of the corresponding guide member 5. Therefore, the support plate 22, the pressing member 23, and the bending member 24 are also in an inclined state. When the edge of the cold-rolled sheet enters the base 21 under the action of the guide member 5, the inclination angle of the base 21 is consistent with that of the cold-rolled sheet, that is, the edge of the cold-rolled sheet is bent while the cold-rolled sheet is in an inclined state.

[0025] Reference Figure 3 As shown, a guide frame 33 is provided at the end of the roller conveyor 3. The guide frame 33 extends downward at an angle to gradually lower the landing point of the bent cold-rolled sheet. Multiple guide rollers 34 are distributed on the guide frame 33. After the cold-rolled sheet is processed, it can fall at a lower position. Workers can place pallets or other supporting tools on the ground to collect the falling cold-rolled sheet directly. Because the landing point is lowered, the cold-rolled sheet is less likely to be damaged.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
