The bending device positions the length of the workpiece by setting a movable baffle and a fixed baffle, and the movable baffle can be moved along the height direction of the bending table under the action of the electric push rod 2, which is convenient for the staff to place the workpiece on the bending table from one end of the bending table near the movable baffle, greatly improving the convenience and efficiency of workpiece placement.

[0027] Example: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problems of traditional bending devices in that they are not accurate enough in positioning the workpiece, are not convenient for loading and unloading, and are not suitable for bending workpieces of different widths. The overall idea is as follows:

[0028] In response to the problems existing in the prior art, the utility model provides a bending device, including a bending table 1, a support arm 11 is fixedly installed at the end of the bending table 1, a hydraulic cylinder 12 is fixedly installed on the support arm 11, a bending block 13 is fixedly connected to the bottom end of the telescopic rod of the hydraulic cylinder 12, a bending groove 14 is provided in the middle of the upper surface of the bending table 1, the bending block 13 is located just above the bending groove 14, two slide grooves 15 are provided on the surface of the bending table 1, a slide rod 4 is slidably installed in each slide groove 15, and a stopper 41 is fixedly installed on both sides of the upper end of each slide rod 4, a bidirectional threaded rod 5 is rotatably installed inside the bending table 1, the bidirectional threaded rod 5 passes through the two slide rods 4 and is threadedly connected to the two slide rods 4, and the two ends of the bending table 1 are connected. The ends are respectively equipped with a movable baffle 2 and a fixed baffle 3, the fixed baffle 3 is fixedly installed at the end of the bending table 1, the movable baffle 2 is slidably installed on the end of the bending table 1, each slide rod 4 is of "I" shape design, the end of the bidirectional threaded rod 5 is fixedly connected with a hand wheel 51, one end of the bending table 1 is fixedly installed with an electric push rod 2 8, the telescopic rod 3 of the electric push rod 2 8 is fixedly connected to the movable baffle 2, the movable baffle 2 and the fixed baffle 3 are arranged along the length direction of the bending table 1, and the two slide rods 4 are arranged along the width direction of the bending table 1, one end of the bending table 1 is fixedly installed with an electric push rod 1 6, the telescopic rod 2 of the electric push rod 1 6 is fixedly connected with a push rod 7, and the push rod 7 is distributed along the width direction of the bending table 1. When bending a workpiece, the workpiece is placed between the movable baffle 2 and the fixed baffle 3, and the hydraulic cylinder 12 is started to move the bending block 13 downward. The bending block 13 will apply a force to the middle of the workpiece, and the workpiece will be bent under the action of the bending groove 14. After the workpiece is bent, the two ends of the workpiece will tilt upward, so the two sets of baffles 41 will not block the moving path of the workpiece. The bending block 13 moves up and resets, and then the electric push rod 6 is started to move the push rod 7 along the width direction of the bending table 1. The movement of the push rod 7 will push the workpiece out after bending, so that it will be out of the bending groove 14 and the bending table 1, realizing the function of automatic unloading. The movable baffle 2 and the fixed baffle 3 position the length of the workpiece. , the movable baffle 2 is slidably installed at one end of the bending table 1, and the electric push rod 2 is started to make the movable baffle 2 move along the height direction of the bending table 1. The movable baffle 2 is moved down so that the movable baffle 2 no longer blocks one end of the bending table 1, which is convenient for the staff to place the workpiece on the bending table 1 from the end of the bending table 1 close to the movable baffle 2, which is convenient for placing the workpiece and more convenient to use. By twisting the handwheel 51, the bidirectional threaded rod 5 is rotated, and the rotation of the bidirectional threaded rod 5 drives the two sliding rods 4 to move relative to each other (closer to or away from each other), so that the two sets of stoppers 41 move relative to each other, so that the gap between the two sets of stoppers 41 can be adjusted, so that it can be suitable for the positioning of workpieces of different widths.

[0029] Working principle:

[0030] The first step is to place the workpiece between the movable baffle 2 and the fixed baffle 3 when bending a long plate-type workpiece, start the hydraulic cylinder 12, and move the bending block 13 downward. The bending block 13 will apply a force to the middle part of the workpiece, and bend the workpiece in cooperation with the action of the bending groove 14. After the workpiece is bent, the two ends of the workpiece will tilt upward, so the two sets of blocks 41 will not block the moving path of the workpiece. The bending block 13 moves up and resets, and then the electric push rod 6 is started to move the push rod 7 along the width direction of the bending table 1. The movement of the push rod 7 will push the workpiece out after bending, so that it will be separated from the bending groove 14 and the bending table 1, realizing the function of automatic unloading.

[0031] In the second step, the movable baffle 2 and the fixed baffle 3 are positioned according to the length of the workpiece. The movable baffle 2 is slidably installed on one end of the bending table 1, and the electric push rod 2 8 is started to move the movable baffle 2 along the height direction of the bending table 1. The movable baffle 2 is moved down so that the movable baffle 2 no longer blocks one end of the bending table 1, which makes it convenient for the staff to place the workpiece on the bending table 1 from the end of the bending table 1 close to the movable baffle 2, making it easier to place the workpiece and more convenient to use.

[0032] The third step is to rotate the bidirectional threaded rod 5 by twisting the handwheel 51, and the rotation of the bidirectional threaded rod 5 drives the two slide rods 4 to move relative to each other (closer to each other or farther away from each other), so that the two groups of blocks 41 move relative to each other, so that the gap between the two groups of blocks 41 can be adjusted, so as to be suitable for positioning workpieces of different widths.

[0033] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments.
