[0002] Agricultural machinery accessories refer to components or accessories used for agricultural machinery and equipment. Their function is to support and enhance the functions and performance of mechanical equipment. Agricultural machinery accessories are usually composed of plates of various materials. Plates are used to manufacture various agricultural machinery parts and structural parts to support and reinforce the entire mechanical equipment. These plates are usually processed by shearing, stamping, bending, welding and other processing techniques to make parts of various shapes and sizes for assembly into various components of agricultural machinery and equipment. Therefore, a bending machine is used when processing the accessory plates to bend the accessory plates into the required shape.

[0003] However, the existing bending machines have the following disadvantages: since the bending machines will clamp the two sides of the accessory plates during the bending process of the agricultural machinery accessory plates, but the shapes of the two sides of the accessory plates may be irregular, the ordinary clamping components cannot stably clamp the two ends of the accessory plates, resulting in the two ends of the accessory being easily offset during the bending process. Therefore, the existing bending machines need to be improved. Utility Model Content

When clamping the accessory plate, the connecting plate is pushed to the appropriate position through the No. 2 electric telescopic rod, and the No. 1 limit plate and the No. 2 limit plate are in contact with both sides of the accessory. Then the handle is rotated to drive the screw to rotate, so that the slider drives the connecting rod to move to one side on the screw. One end of the connecting rod pushes one end of the No. 1 limit plate or the No. 2 limit plate, and at the same time, the other end of the No. 1 limit plate or the No. 2 limit plate rotates around the middle movable axis. The inclination angle of the No. 1 limit plate and the No. 2 limit plate can be quickly adjusted, so that the No. 1 limit plate and the No. 2 limit plate are against the irregular position of the accessory plate, the accessory plate can be stably clamped, the accessory plate is prevented from being offset, and the working quality of the bending machine is improved.

[0015] 2. A supporting mechanism is provided.

[0023] according to Figure 1-2 and Figure 4As shown, the support mechanism 8 includes a support plate 801, a No. 1 electric telescopic rod 802, an extension plate 803, a gear 804 and a semi-toothed disc 805. The outer side of the rotating shaft 12 is fixedly sleeved with the extension plate 803, one side of the extension plate 803 is connected to the support plate 801 through the No. 1 electric telescopic rod 802, the middle part of the rotating shaft 12 is fixedly sleeved with a gear 804, one side of the gear 804 is meshed with a semi-toothed disc 805, one side of the semi-toothed disc 805 is connected to the motor 14, and the motor 14 is located in the built-in groove of the body 1.

[0024] During specific implementation, the area of ​​the working table of the bending machine is usually fixed, which is not convenient to adjust according to the length of the agricultural machinery accessory plate, resulting in unstable placement of one end of the accessory and requiring manual holding. When the accessory plate is long, the motor 14 can drive the semi-toothed disc 805 to rotate, and then the semi-toothed disc 805 meshes with the gear 804 and drives the gear 804 to rotate, and then the gear 804 drives the shaft 12 to rotate, so that the shaft 12 drives the extension plate 803 to rotate, and after the extension plate 803 is adjusted to a height level with the surface of the machine body 1, the support plate 801 is pushed upward by the No. 1 electric telescopic rod 802, and the support plate 801 is adjusted to a suitable height. Then the support plate 801 supports one end of the accessory plate, which can make the accessory placement more stable, reduce the labor consumption of the staff, and improve the convenience of the bending machine.

[0025] according to Figure 1-3 As shown, the limiting mechanism 11 includes a No. 2 electric telescopic rod 111, a screw 112, a connecting plate 113, a handle 114, a slider 115 and a connecting rod 116. One side of the fixed frame 13 is connected to the connecting plate 113 through the No. 2 electric telescopic rod 111. A screw 112 is installed in the built-in groove of the connecting plate 113 through a bearing. One end of the screw 112 is connected to the handle 114. The outer thread of the screw 112 is sleeved with a slider 115. One side of the slider 115 is connected to the connecting rod 116 through a movable shaft. One end of the connecting rod 116 is connected to the No. 1 limiting plate 9 and the No. 2 limiting plate 10 through a movable shaft. The No. 1 limiting plate 9 and the No. 2 limiting plate 10 are connected through a movable shaft.

[0026] In specific implementation, since the shapes of both sides of the accessory plate may be irregular, ordinary clamping components cannot stably clamp the two ends of the accessory plate, resulting in the two ends of the accessory being easily offset during the bending process. When bending, the accessory plate can be placed on the support roller 7, and then the connecting plate 113 can be pushed to a suitable position through the second electric telescopic rod 111, and the first limit plate 9 and the second limit plate 10 can be made to contact with both sides of the accessory, and then the handle 114 can be rotated to make the handle 114 drive the screw 112 to rotate. The slider 115 drives the connecting rod 116 to move to one side on the screw 112, and one end of the connecting rod 116 pushes one end of the No. 1 limit plate 9 or the No. 2 limit plate 10. At the same time, the other end of the No. 1 limit plate 9 or the No. 2 limit plate 10 rotates around the middle movable axis, and the inclination angle of the No. 1 limit plate 9 and the No. 2 limit plate 10 can be quickly adjusted, so that the No. 1 limit plate 9 and the No. 2 limit plate 10 are against the irregular position of the accessory plate, which can stably clamp the accessory plate to prevent the accessory plate from shifting, thereby improving the working quality of the bending machine.

[0027] Working principle: When using this bending machine with an auxiliary limiting structure, first, place the accessory sheet to be bent on the support roller 7, and at the same time, unfold the extension plate 803 through the support mechanism 8 according to the length of the accessory sheet, so that the support plate 801 supports one end of the accessory sheet, and at the same time, the other end of the accessory sheet is against one side of the blocking assembly 6 to limit the position of the other end of the accessory sheet, and then the two sides of the accessory sheet are limited by the limiting mechanism 11 to prevent deviation, and then the hydraulic cylinder 3 is started to push the bending head 4 downward, and the bending head 4 generates downward pressure on the upper surface of the accessory sheet, and makes the lower surface of the accessory sheet contact with the pressing plate 5, so that the accessory sheet is bent, and the support mechanism 8 and the limiting mechanism 11 improve the stability and working quality of the bending machine.
