Description

Technical Field

[0001] This utility model relates to a processing equipment, and more particularly to a cold bending forming equipment. Background Technology

[0002] Cold bending refers to the process of processing metal sheet or strip into profiles or parts of specific shapes and sizes by mechanical bending (such as roll bending, pressure bending, drawing bending, folding, etc.) at room temperature. The products are called cold-formed profiles.

[0003] When the equipment performs cold bending on the product, the hydraulic device drives the extruder to squeeze the workpiece, causing the workpiece to bend and deform. However, during the bending process, the two sides of the workpiece at the bending position are prone to warping and deformation, which results in a large deviation in the overall shape and size of the workpiece after processing. Utility Model Content

[0004] Therefore, it is necessary to provide a cold bending forming equipment to address the shortcomings of existing technologies.

[0005] A cold bending forming equipment includes a base frame, several sets of support and limiting components, two sets of positioning conveying modules, a bending module, a pressure plate, and an upper limit module. The support and limiting components, positioning conveying modules, and bending modules are all mounted on the base frame. The two positioning conveying modules and the bending module are arranged in a T-shape. The positioning conveying modules are located on both sides in front of the bending module. The support and limiting components are distributed along a fixed direction during product processing. The pressure plate is simultaneously mounted on different sets of support and limiting components. The upper limit module is located above the pressure plate. Each set of support and limiting components includes two fixed frames, a first guide roller, and a second guide roller. The two ends of the first guide roller are respectively mounted on the two fixed frames, and the two ends of the second guide roller are respectively mounted on the two fixed frames. During processing, the upper limit module drives the pressure plate to press down, causing the second guide roller of the support and limiting component to be pressed down to a state of close contact with the product or with a slight gap.

[0006] In one embodiment, the fixing frame includes a guide sleeve, an upper guide block and a lower guide block mounted on the guide sleeve, a connecting frame mounted on the upper guide block, and a linkage rod connected to the connecting frame. The upper guide block, the lower guide block and the connecting frame are disposed inside the guide sleeve. The guide sleeve guides the upper guide block. The two ends of the first guide roller are respectively mounted on the lower guide blocks of the two fixing frames through bearings. The two ends of the second guide roller are respectively mounted on the upper guide blocks of the two fixing frames through bearings.

[0007] In one embodiment, the fixing frame further includes a return spring disposed between the upper guide block and the lower guide block.

[0008] In one embodiment, the bottom of the linkage rod passes vertically through the guide sleeve and is mounted on the connecting frame.

[0009] In one embodiment, the pressure plate is planar on both its upper and lower sides, and the pressure plate is fixedly installed with linkage rods on different sets of support and limiting components.

[0010] In one embodiment, the bending module includes two guide rails, a first mounting base slidably mounted on the two guide rails, two first bearings mounted on the first mounting base, a first roller mounted on the two first bearings, and a first drive cylinder disposed behind and connected to the first mounting base. The two first bearings are arranged opposite each other in the vertical direction, and the first roller is mounted on the two first bearings in the vertical direction. The first roller can rotate around the axis of the first bearing.

[0011] In one embodiment, the positioning and conveying module includes a second mounting base, two second bearings mounted on the second mounting base, a second roller mounted on the two second bearings, and a drive motor connected to the second roller. The two second bearings are arranged opposite each other in the vertical direction, and the second roller is mounted on the two second bearings in the vertical direction. The second roller can rotate around the axis of the second bearing.

[0012] In one embodiment, the upper limit module includes a second hydraulic cylinder and a pressure block. The pressure block is located at the bottom of the second hydraulic cylinder and is connected to the second hydraulic cylinder. The second hydraulic cylinder drives the pressure block to press down or lift up.

[0013] The beneficial effects of this utility model cold bending forming equipment are as follows: by setting up a support limiting component, a pressure plate and an upper limit module, during the processing, the upper limit module drives the pressure plate to press down, so that the first guide roller of the support limiting component is pressed down to a state of being in close contact with the product or having a slight gap, which effectively prevents the product from warping up during the processing, prevents the overall shape and size of the workpiece from having a large deviation after processing, and ensures the processing quality of the product.

[0024] Please see Figures 1 to 4 This utility model provides a cold bending forming equipment for cold bending a metal product 100. The cold bending forming equipment includes a base frame 10, several sets of support and limiting components 40, two sets of positioning conveying modules 30, a bending module 20, a pressure plate 50, and an upper limit module 60. The support and limiting components 40, positioning conveying modules 30, and bending modules 20 are all mounted on the base frame 10. The two positioning conveying modules 30 and the bending module 20 are arranged in a T-shape. The positioning conveying modules 30 are located on both sides in front of the bending module 20. The support and limiting components 40 are distributed along a fixed direction during the processing of the product 100. The pressure plate 50 is simultaneously mounted on different sets of support and limiting components 40. The upper limit module 60 is located above the pressure plate 50.

[0025] The bending module 20 includes two guide rails 21, a first mounting base 22 slidably mounted on the two guide rails 21, two first bearings 23 mounted on the first mounting base 22, a first roller 24 mounted on the two first bearings 23, and a first drive cylinder 25 located behind and connected to the first mounting base 22. The two first bearings 23 are vertically opposite each other, and the first roller 24 is vertically mounted on the two first bearings 23. The first roller 24 can rotate around the axis of the first bearing 23. Guided by the two guide rails 21, the first drive cylinder 25 drives the first mounting base 22 to move to a position between the two sets of positioning and conveying modules 30, or to move backward. During the movement, the first mounting base 22 drives the first roller 24 to move synchronously.

[0026] Each positioning and conveying module 30 includes a second mounting base 31, two second bearings 32 mounted on the second mounting base 31, a second roller 33 mounted on the two second bearings 32, and a drive motor 34 connected to the second roller 33. The two second bearings 32 are arranged opposite each other in the vertical direction, and the second roller 33 is mounted on the two second bearings 32 in the vertical direction. The second roller 33 can rotate around the axis of the second bearing 32.

[0027] Each set of support and limiting components 40 includes two fixed frames 41, a first guide roller 42 and a second guide roller 43. The two ends of the first guide roller 42 are respectively mounted on the two fixed frames 41, and the two ends of the second guide roller 43 are respectively mounted on the two fixed frames 41.

[0028] Specifically, each fixed frame 41 includes a guide sleeve 411, an upper guide block 412 and a lower guide block 413 installed on the guide sleeve 411, a return spring 414 disposed between the upper guide block 412 and the lower guide block 413, a connecting frame 415 installed on the upper guide block 412, and a linkage rod 416 connected to the connecting frame 415. The upper guide block 412, the lower guide block 413 and the connecting frame 415 are disposed inside the guide sleeve 411. The guide sleeve 411 guides the upper guide block 412. The bottom of the linkage rod 416 passes through the guide sleeve 411 in a vertical direction and is installed on the connecting frame 415. The two ends of the first guide roller 42 are respectively mounted on the lower guide blocks 413 of the two fixed frames 41 through bearings. The two ends of the second guide roller 43 are respectively mounted on the upper guide blocks 412 of the two fixed frames 41 through bearings.

[0029] The pressure plate 50 is arranged in a planar manner on its upper and lower sides, and the pressure plate 50 is installed and fixed with the linkage rod 416 on the support and limiting components 40 of different groups. The upper limit module 60 includes a second hydraulic cylinder 61 and a pressure block 62. The pressure block 62 is located at the bottom of the second hydraulic cylinder 61 and is connected to the second hydraulic cylinder 61. The second hydraulic cylinder 61 drives the pressure block 62 to press down or lift up.

[0030] Before processing product 100, product 100 is placed on different sets of support and limiting components 40. The return spring 414 on the fixing frame 41 pushes the upper pressure block 62, creating a gap between the upper guide block 412 and the lower guide block 413 to place product 100. Product 100 passes between the first guide roller 42 and the second guide roller 43 and is pressed down on the first guide roller 42. Product 100 also passes between the positioning conveying module 30 and the bending module 20. The second hydraulic cylinder 61 of the bending module 20 drives the pressure block 62 to press down to the set position. During the pressing down of the pressure block 62, the pressure plate 50 is pushed down, and the pressure plate 50 presses down the linkage rod 416. During the pressing down, the linkage rod 416 drives the upper guide block 412 and the second guide roller 43 to press down to the set position. When the second guide roller 43 is pressed down to the set position, the second guide roller 43 and product 100 are either in contact or have a slight gap. The first drive cylinder 25 drives the first mounting base 22 and the first roller 24 to move between the two sets of positioning and conveying modules 30. Since the second rollers 33 of the two positioning and conveying modules 30 limit the product 100, the first roller 24 deforms the product 100 during the movement. The second rollers 33 and the first roller 24 of the two positioning and conveying modules 30 form a channel. The drive motor 34 of the positioning and conveying module 30 drives the second rollers 33 to rotate. The second rollers 33 drive the product 100 to move along the channel, so that the product 100 is bent along the path formed by the second rollers 33 and the first roller 24. After the product 100 is processed, the second hydraulic cylinder 61 of the bending module 20 drives the pressure block 62 to rise, and the return spring 414 pushes the upper guide block 412 and the second guide roller 43 back to their original positions.

[0031] The beneficial effects of this utility model cold bending forming equipment are as follows: by setting the support limiting component 40, the pressure plate 50 and the upper limit module 60, during the processing, the upper limit module 60 drives the pressure plate 50 to press down, so that the second guide roller 43 of the support limiting component 40 is pressed down to a state of being in contact with the product 100 or having a slight gap, which effectively prevents the product 100 from warping up during the processing, prevents the overall shape and size of the workpiece from having a large deviation after processing, and ensures the processing quality of the product 100.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
