Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to an automatic bending and positioning device for sheet metal parts. Background Technology

[0002] Bending sheet metal parts is a common process in manufacturing, aimed at meeting the needs of different application scenarios and improving the functionality, aesthetics, and structural strength of products.

[0003] When processing sheet metal parts, the bending blocks are mainly moved by hydraulic cylinders. The sheet metal parts are bent by the cooperation of V-grooves. During the bending process, since there is no structure for positioning the sheet metal parts next to the V-grooves, the position of the sheet metal parts needs to be manually adjusted when bending other parts of the sheet metal parts. Manual positioning is inefficient and seriously slows down the speed of the entire production process. Utility Model Content

[0004] To overcome the shortcomings of manually adjusting the position of sheet metal parts when bending other parts, which is inefficient and severely slows down the entire production process, this utility model provides an automatic bending and positioning device for sheet metal parts.

[0005] The technical solution of this utility model is: an automatic bending and positioning device for sheet metal parts, including a frame, a mounting box, a cylinder, a lifting frame, bending plates, horizontal guide rods, positioning plates, a first bidirectional lead screw, and an adjustment mechanism. The mounting box is connected to the top of the frame, and an opening is opened in the mounting box. A cylinder is installed in the mounting box, and a lifting frame is connected to the telescopic rod of the cylinder. Bending plates are slidably connected to the left and right sides of the bottom of the lifting frame. Two horizontal guide rods are connected to the top of the frame, and two positioning plates are slidably connected to the two horizontal guide rods. The first bidirectional lead screw is rotatably connected to the top of the frame, and both positioning plates are threadedly connected to the first bidirectional lead screw. The adjustment mechanism is used to adjust the distance between the two bending plates.

[0006] Furthermore, the adjustment mechanism includes a sliding support plate, a second double-acting screw, and a vertical guide rod. Two sliding support plates for supporting sheet metal parts are slidably connected to the top of the frame. The sliding support plates slide through the mounting box. The second double-acting screw is rotatably connected to the mounting box. Both sliding support plates are threaded to the second double-acting screw. A vertical guide rod is connected to the top of each sliding support plate. The vertical guide rod slides through the bent plate.

[0007] Furthermore, it also includes an electric guide rail and a push block. The electric guide rail is installed on the top of the frame and is connected to the mounting box. The push block is connected to the slider of the electric guide rail.

[0008] Furthermore, it also includes a fixed support plate, a mounting plate, electric push rods, and a pressure plate. The top of the electric guide rail is connected to a fixed support plate for supporting the sheet metal parts. The push block and the fixed support plate are slidably connected. The mounting box is connected to a mounting plate, and two electric push rods are mounted on the mounting plate. The telescopic rods of the two electric push rods are connected to a pressure plate for pressing the sheet metal parts.

[0009] Furthermore, it also includes a mounting bracket, a guide plate, and a baffle. The mounting bracket is connected to the frame, the top of the mounting bracket is connected to the guide plate, and the baffle is connected to the guide plate. The push block can push the bent sheet metal part onto the guide plate, and the bent sheet metal part slides forward along the guide plate. The baffle blocks the bent sheet metal part.

[0010] Furthermore, it also includes ball bearings, with evenly spaced ball bearings rotating on the top of the guide plate.

[0011] This invention has the following advantages: The extension of the cylinder's telescopic rod can move the bending plate downwards, allowing it to bend the sheet metal part. Rotating the second bidirectional lead screw can move two sliding support plates in opposite directions, adjusting the distance between them. Simultaneously, the distance between the two bending plates can be adjusted accordingly, quickly adjusting the bending position of the sheet metal part. Furthermore, both sides of the sheet metal part can be bent in a single operation, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] like Figure 1-Figure 5 As shown, an automatic bending and positioning device for sheet metal parts includes a frame 1, a mounting box 2, a cylinder 4, a lifting frame 5, bending plates 6, horizontal guide rods 7, positioning plates 8, a first bidirectional lead screw 9, and an adjustment mechanism. The mounting box 2 is bolted to the top of the frame 1. An opening 3 is opened on the front side of the mounting box 2. The cylinder 4 is bolted to the middle of the upper part of the mounting box 2. The lower end of the telescopic rod of the cylinder 4 is connected to the lifting frame 5. Bending plates 6 are slidably connected to the left and right sides of the bottom of the lifting frame 5. Horizontal guide rods 7 are connected to the front and rear sides of the top of the frame 1. Two positioning plates 8 are slidably connected to the two horizontal guide rods 7. The first bidirectional lead screw 9 is rotatably connected to the middle of the top of the frame 1. Both positioning plates 8 are threaded to the first bidirectional lead screw 9. The threads on the two positioning plates 8 are in opposite directions, so the first bidirectional lead screw 9 can drive the two positioning plates 8 to move in opposite directions. The adjustment mechanism is used to adjust the distance between the two bending plates 6.

[0021] like Figure 3-Figure 5 As shown, the adjustment mechanism includes a sliding support plate 10, a second bidirectional lead screw 11, and a vertical guide rod 12. The sliding support plate 10 is slidably connected to the top left and right sides of the frame 1. The sliding support plate 10 slides through the rear side of the mounting box 2. The second bidirectional lead screw 11 is rotatably connected to the rear side of the mounting box 2. Both sliding support plates 10 are threadedly connected to the second bidirectional lead screw 11. The threads on the two sliding support plates 10 are in opposite directions, so the second bidirectional lead screw 11 can drive the two sliding support plates 10 to move in opposite directions. The top rear side of the sliding support plate 10 is bolted to the vertical guide rod 12. The vertical guide rod 12 slides through the bent plate 6, and the bent plate 6 can move up and down along the vertical guide rod 12.

[0022] The worker places the sheet metal part onto the two sliding support plates 10 through opening 3. The positioning plate 8 positions the sheet metal part to prevent it from shifting. Then, the extension rod of the control cylinder 4 extends, causing the lifting frame 5 and bending plate 6 to move downwards. The bending plate 6 moves downwards and contacts the sheet metal part, bending it. After bending, the extension rod of the control cylinder 4 shortens, causing the lifting frame 5 and bending plate 6 to move upwards, resetting the bending plate 6. Rotating the first bidirectional lead screw 9 moves the two positioning plates 8 in opposite directions. Adjusting the distance between the two positioning plates 8 can be done according to the sheet metal part's position. The distance between the two positioning plates 8 can be adjusted to accommodate sheet metal parts of different lengths. Rotating the second bidirectional lead screw 11 can move the two sliding support plates 10 in opposite directions. Adjusting the distance between the two sliding support plates 10 can be done according to the bending position of the sheet metal part. When the sliding support plates 10 move, they will also drive the vertical guide rod 12 and the bending plate 6 to move, and adjust the distance between the two bending plates 6 accordingly. This allows for quick adjustment of the bending position of the sheet metal part, and both sides of the sheet metal part can be bent in one operation, thereby improving work efficiency.

[0023] like Figure 6 As shown, it also includes an electric guide rail 13 and a push block 14. The electric guide rail 13 is bolted to the middle of the top of the frame 1. The rear side of the electric guide rail 13 is bolted to the rear side of the mounting box 2. The push block 14 is connected to the slider of the electric guide rail 13.

[0024] like Figure 1 As shown, it also includes a mounting bracket 18, a guide plate 19, and a baffle 20. The mounting bracket 18 is bolted to the front side of the frame 1, the guide plate 19 is bolted to the top of the mounting bracket 18, and the baffle 20 is bolted to the front side of the guide plate 19.

[0025] like Figure 1 As shown, it also includes ball bearings 21, and the top of the guide plate 19 is rotatably connected with ball bearings 21 at even intervals.

[0026] After the sheet metal part is bent, the electric guide rail 13 drives the push block 14 to move forward. The push block 14 pushes the bent sheet metal part forward and pushes it onto the guide plate 19. The bent sheet metal part slides forward along the guide plate 19. The baffle 20 can block the bent sheet metal part, making it convenient for workers to pick up the bent sheet metal part. Under the action of the ball bearing 21, friction between the bent sheet metal part and the guide plate 19 can be avoided, thereby preventing wear on the bent sheet metal part.

[0027] like Figure 6As shown, it also includes a fixed support plate 15, a mounting plate 151, an electric push rod 16, and a pressure plate 17. The top of the electric guide rail 13 is connected to the fixed support plate 15. The push block 14 and the fixed support plate 15 are slidably connected. The mounting plate 151 is bolted to the upper middle of the mounting box 2. The electric push rod 16 is bolted to both the front and rear of the mounting plate 151. The lower ends of the telescopic rods of the two electric push rods 16 are connected to the pressure plate 17.

[0028] When bending the sheet metal part, the telescopic rod of the electric push rod 16 is extended, which drives the pressure plate 17 to move downward. The pressure plate 17 can press down the sheet metal part to prevent the middle of the sheet metal part from arching upward. The fixed support plate 15 can support the sheet metal part to prevent the pressure plate 17 from bending the sheet metal part.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
