Description

Technical Field

[0002] The bending device for sheet metal processing is a mechanical equipment specially used to bend metal sheets to form specific shapes. It can bend metal sheets into specific angles and shapes to meet design and engineering requirements. In the existing technology, a bending groove is usually provided at the upper end of the workbench, and a bending head that is compatible with the bending groove is provided directly above the bending groove. A limiting component is provided on the workbench. However, in this method, the limiting component can only limit the front and rear end directions of the sheet metal part, and cannot limit the left and right end directions of the sheet metal part. Without the limit in the left and right end directions, the sheet metal part may undergo lateral displacement during the bending process, resulting in inaccurate bending position and affecting the dimensional accuracy of the final product.

[0003] For example, the utility model with the announcement number CN217889139U discloses a bending device for sheet metal processing. In the technical solution of this patent, a bending groove is provided on the upper end surface of the workbench, a bending head adapted to the bending groove is provided directly above the bending groove, a sheet metal part is placed in the middle of the workbench, and limiting components for limiting the front and rear ends of the sheet metal part are provided at both ends of the workbench. However, in this method, only the front and rear ends of the sheet metal can be limited, and the left and right ends of the limiting components cannot be limited. The lack of side limit means that the sheet metal part may have a position offset in the left and right directions, resulting in inaccurate size and position after bending, affecting the quality of the final product.

[0021] To better understand the present utility model, the following further clarifies the content of the present utility model in conjunction with embodiments. However, the protected content of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0022] Such as Figure 1 、 2, as shown in FIGS. 3, a bending device for sheet metal processing includes a workbench 101. At the upper end of the workbench 101, there is a support frame 102. At the upper end of the support frame 102, there is a telescopic push rod 103. The output end of the telescopic push rod 103 extends into the interior of the support frame 102 and is connected to a bending head 104. In the middle of the workbench 101, there is a bending groove 110 adapted to the bending head 104. On the upper end of the workbench 101, there is a sheet metal part 105 placed. At both ends of the workbench 101, there is a first limiting component for limiting the front and rear ends of the sheet metal part 105. At the left end of the workbench 101, there is a second limiting component for limiting the left end of the sheet metal part 105. The second limiting component includes a fixing plate 201 arranged at the left end of the workbench 101. At the front end of the fixing plate 201, there is a rotating column 202 rotatably arranged. On the rotating column 202, there is a first connecting rod 203. The end of the first connecting rod 203 away from the rotating column 202 is rotatably connected to a second connecting rod 204. The end of the second connecting rod 204 away from the first connecting rod 203 is rotatably connected to a second limiting plate 205. At the rear end of the fixing plate 201, there is a second motor 206. The output end of the second motor 206 is connected to the rotating column 202 through a coupling. At one end of the workbench 101 close to the second limiting component, there is a scale 304. Starting the second motor 206 can make the rotating column 202 rotate. The rotation of the rotating column 202 drives the first connecting rod 203 to rotate. The rotation of the first connecting rod 203 drives the second connecting rod 204 to rotate. The second connecting rod 204 pushes the second limiting plate 205 to move, so as to limit and align the left end of the sheet metal part 105. Through the limiting and alignment, it can ensure that the position of the sheet metal part 105 is consistent in each bending operation, thereby improving the bending accuracy and reducing the dimensional error caused by the position deviation.

[0023] As Figure 1 , 2 shown, the first limiting component includes sliding grooves symmetrically arranged on the workbench 101. Inside the sliding grooves, there are two-way lead screws 106 rotatably arranged. At both ends of the two-way lead screws 106, there are sliding blocks 107 threadedly connected. On the upper ends of the sliding blocks 107, there are first limiting plates 108. At the front end of the workbench 101, there is a first motor 109 corresponding to the two-way lead screw 106. The output end of the first motor 109 is connected to the two-way lead screw 106 through a coupling.

[0024] As Figure 1 , 4 shown, a guide rod 301 is slidably connected to the upper end of the support frame 102. The upper end of the guide rod 301 is connected to a guide plate 302, and the lower end is connected to the upper side wall of the bending head 104. By arranging the guide rod 301, it can assist the bending head 104 to descend vertically, avoid deviation, and improve the stability of the equipment.

[0025] As Figure 1 , 4As shown in the figure, support bases 305 are evenly arranged at the lower end of the workbench 101. Anti-slip stripes are provided on the outer wall of the bottom of each support base 305. By arranging the support bases 305, a good supporting effect on the workbench 101 is achieved, greatly improving the stability of the workbench 101.

[0026] During use, place the sheet metal part 105 on the workbench 101. First, start the first motor 109 to drive the bidirectional lead screw 106 to rotate, so that the sliders 107 can approach or move away from each other. Then, the sliders 107 drive the first limiting plate 108 to approach or move away from each other, so as to limit the front and rear ends of the sheet metal part 105. Next, start the second motor 206 to drive the second rotating column 202 to rotate. The second rotating column 202 drives the first connecting rod 203 to rotate, the first connecting rod 203 drives the second connecting rod 204 to rotate, and the rotation of the second connecting rod 204 drives the second limiting plate 205 to move, so as to limit and align the left end of the sheet metal part 105, enabling the sheet metal parts 105 of the same model to obtain a highly consistent bending effect during mass production. Then, start the telescopic push rod 103 to lower the bending head 104 to cooperate with the bending groove 110 to bend the sheet metal part 105.

[0027] According to another embodiment of the present invention, as Figure 1 、 4 shown in the figure, limiting pads 303 are provided on the inner surfaces of the first limiting plate 108 and the second limiting plate 205. The limiting pads 303 can reduce friction when the workpiece contacts the first metal limiting plate 108 and the second limiting plate 205, prevent the surface of the workpiece from being scratched or damaged, and maintain the appearance quality of the workpiece.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
