Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an automatic bending machine for metal frames. Background Technology

[0002] Bending metals and alloys are widely used in various fields. For example, the frames of electronic billboards are made of aluminum. A rectangular aluminum frame can be formed by bending aluminum strips. The main machine for processing aluminum frames is a bending machine, which bends aluminum strips multiple times to form the aluminum frame.

[0003] Existing bending machines can only bend one corner at a time when processing aluminum strips. This usually involves bending a long strip of aluminum multiple times. Furthermore, the machine needs to continuously feed the aluminum strip during the bending process, which can easily lead to insufficient processing accuracy. In addition, the method of bending only one corner at a time has a certain impact on processing efficiency. Therefore, we propose an improved automatic bending machine for metal frames.

A second sliding groove is formed in the middle of the main board, and a second slider is slidably connected within the second sliding groove. A mounting block is fixedly connected to the front end face of the second slider. Auxiliary bending heads are fixedly connected to both sides of the mounting block.

[0013] This utility model provides an automatic bending machine for metal frames, which has the following advantages:

[0014] (1) Compared with the existing technology, this automatic metal frame bending machine, through the coordinated structure of a main board, mounting shaft, conveyor wheel, slide 1, lead screw 1, slider 1, bending head 1, slide 2, lead screw 2, slider 2, mounting block, auxiliary bending head, and bending head 2, can drive slider 2 to move by rotating lead screw 2, thereby driving the mounting block to descend, and then driving bending head 2 to press against the middle of the aluminum strip. With the cooperation of the conveyor wheel, the aluminum strip is bent.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Example:

[0023] Depend on Figures 1-4 As shown, this utility model provides an automatic metal frame bending machine, including a main board 1. Multiple mounting shafts 2 are rotatably connected to the front end face of the main board 1 near the lower position. Conveyor wheels 3 are fixedly connected to the outer walls of the mounting shafts 2. A baffle 4 is fixedly connected to one side of the front end face of the main board 1 to restrict the aluminum strip and prevent it from sliding out of the device. A second sliding groove 9 is provided in the middle of the main board 1. A second slider 11 is slidably connected within the second sliding groove 9. A mounting block 12 is fixedly connected to the front end face of the second slider 11. Auxiliary bending heads 13 are fixedly connected to both sides of the mounting block 12. The auxiliary bending heads 13 are used to cooperate with a first bending head 8 for bending processing. A second bending head 14 is fixedly connected to the lower end face of the mounting block 12. The second bending head 14 is used to press the middle of the aluminum strip for the first bending. A first sliding groove 5 is provided on both sides of the main board 1. A first slider 7 is slidably connected within each of the two first sliding grooves 5. A first bending head 8 is fixedly connected to the outer wall of each of the two first sliders 7 on opposite sides.

[0024] Through the above technical solution, the device can bend the aluminum strip without moving it, thereby improving the bending accuracy. Furthermore, it can bend both ends simultaneously during the second bending process, thereby improving efficiency.

[0025] Multiple conveyor wheels 3 are arranged in a straight line. A conveyor motor is fixedly connected to the rear end of the main board 1. The output end of the conveyor motor is fixedly connected to the rear end of the mounting shaft 2 on the side away from the baffle 4. The conveyor motor drives the connected mounting shaft 2 to rotate, which in turn drives the conveyor wheels 3 to rotate, thereby realizing the conveying of aluminum strips.

[0026] A lead screw 10 is rotatably connected inside the slide groove 2 9, and a slider 2 11 is threadedly connected to the outer wall of the lead screw 2 10. Both outer walls of the slider 2 11 slide against the inner wall of the slide groove 2 9. The slider 2 11 moves stably inside the slide groove 2 9 by rotating the lead screw 2 10.

[0027] A lead screw 6 is rotatably connected inside the slide groove 5, and a slider 7 is threadedly connected to the outer wall of the lead screw 6. The upper and lower inner walls of the slider 7 are slidably attached to the inner wall of the slide groove 5. The slider 7 moves stably inside the slide groove 5 by rotating the lead screw 6.

[0028] A motor is fixedly connected to the upper end of the main board 1. The output end of the motor is fixedly connected to the upper end of the lead screw 10. The motor drives the lead screw 10 to rotate, thereby controlling the movement of the slider 11.

[0029] Motor 2 is fixedly connected to both sides of the main board 1. The output ends of the two motors 2 are fixedly connected to one end of the two lead screws 6 respectively. The motors 2 drive the lead screws 6 to rotate, thereby controlling the movement of the slider 7.

[0030] A mounting plate 15 is fixedly connected to the rear end of the main board 1. A cylinder 16 is fixedly connected to the mounting plate 15. A fixing plate 17 is fixedly connected to the output end of the cylinder 16. A push rod 18 is fixedly connected to the fixing plate 17. The push rod 18 passes through the main board 1. The cylinder 16 drives the fixing plate 17 to move, which in turn drives the push rod 18 to move, pushing the aluminum frame out from the front end of the main board 1 and causing it to fall off.

[0031] There are four push rods 18 in total, and the four push rods 18 are arranged in a rectangular shape on the main board 1. The four push rods 18 push the four sides of the aluminum frame respectively, so that the force is more evenly distributed and the aluminum frame can be stably moved out of the bending head.

[0032] Working principle: The aluminum strip to be bent is fed by the rotating conveyor wheel 3. After one end of the aluminum strip is pressed against the baffle 4, the rotation of the conveyor wheel 3 is stopped. Then, the motor is started to drive the lead screw 10 to rotate, which in turn drives the mounting block 12 to move through the slider 11. This causes the bending head 14 to press against the middle of the aluminum strip. With the cooperation of the conveyor wheel 3, the aluminum strip is bent. When both ends of the aluminum strip are attached to the outer wall of the bending head 14, the motor is started to drive the lead screw 6 to rotate, which in turn drives the bending head 8 to move through the slider 7. The auxiliary bending head 13 simultaneously bends the two ends of the aluminum strip, thereby forming a diamond frame structure and completing the bending process of the aluminum frame.

[0033] Then, start the motor to drive the lead screw 10 to reverse. Following the same principle, the mounting block 12 will rise. Since the aluminum frame is attached to the outer wall of the auxiliary bending head 13 and the second bending head 14, the aluminum frame can be lifted up. When the mounting block 12 moves to the center of the main board 1, start the cylinder 16 to drive the fixing plate 17 to move, and then push the aluminum frame out through the push rod 18 to complete the unloading.
