[0018] 2. By the rotation of the output end of the servo motor, the bidirectional lead screw can be driven to rotate, so that the two lead screw nuts in the middle of the bidirectional lead screw move towards the side away from or close to each other. And because two lead screw nuts are sleeved and installed in the middle of the bidirectional lead screw, and the two lead screw nuts are respectively connected to the two positioning plates, the two positioning plates can be moved towards the side away from or close to each other, thereby adjusting the distance between the two support plates.

And the two limit clamps can play a role in positioning the two sides of the plate, so that the plate is placed on the support plate more accurately without tilting. And because of the elasticity of the spring, it can play a role in positioning the two limit clamps and enable the limit clamps to have a certain buffer, thus playing a role in limiting plates of different specifications and ensuring the stability of the plate.

[0029] like Figure 1 , 6 As shown, a first slide groove 3 is opened on the upper surface of the workbench 1, and a first slider 19 is fixedly installed at the lower end of the positioning plate 2. The first slider 19 is slidably installed in the first slide groove 3. By sliding the first slider 19 in the first slide groove 3, the positioning plate 2 can be more stable when moving.

[0030] like Figure 1 , 2 As shown, connecting rods 15 are fixedly installed on the sides of the two screw thread sleeves 14, and one end of the two connecting rods 15 is fixedly set on the positioning plate 2.

[0031] like Figure 1 , 4As shown, a mounting sleeve rod 17 is fixedly installed at the output end of the first hydraulic cylinder 16. The mounting sleeve rod 17 is located between two guide plates 8. At both ends of the mounting sleeve rod 17 that are far away from each other inside, sliding rods 18 are slidably installed.

This device can bend the two ends of the plate simultaneously, can be adjusted according to the specifications of the plate, and can bend the two ends of the plate at the same time. This device is easy to operate and can position the plate to ensure the quality of bending.

[0033] As Figure 2 , 7As shown, the positioning component 11 includes a second chute 1101, a limiting clamping plate 1102, and a through slot 1103. The upper surface of the support plate 5 is provided with the second chute 1101. The limiting clamping plates 1102 are slidably mounted on both sides of the upper surface of the support plate 5. The guide plate 8 is provided with the through slot 1103. Two second sliders 1104 are slidably mounted inside the second chute 1101. The two second sliders 1104 are respectively connected to the two limiting clamping plates 1102. The two second sliders 1104 are connected by a spring 1105. And because the upper surface of the support plate 5 is provided with the second chute 1101, the limiting clamping plates 1102 are slidably mounted on both sides of the upper surface of the support plate 5, the guide plate 8 is provided with the through slot 1103, two second sliders 1104 are slidably mounted inside the second chute 1101, the two second sliders 1104 are respectively connected to the two limiting clamping plates 1102, the two second sliders 1104 are connected by a spring 1105, and the two limiting clamping plates 1102 can play a role in positioning the two sides of the plate, so that the plate is placed more accurately at the position of the support plate without tilting. And because of the elasticity of the spring 1105, it can play a role in positioning the two limiting clamping plates 1102, and can make the limiting clamping plates 1102 have a certain buffer, so as to play a role in limiting plates of different specifications and ensure the stability of the plate.

[0034] The working principle of this iron box processing plate bending equipment:

[0035] During use, first, the output end of the servo motor 13 rotates, which can drive the bidirectional lead screw 12 to rotate, enabling the two lead screw sleeves 14 in the middle of the bidirectional lead screw 12 to move towards the side away from or close to each other. Since two lead screw sleeves 14 are sleeved and installed in the middle of the bidirectional lead screw 12, and the two lead screw sleeves 14 are respectively connected to the two positioning plates 2, the two positioning plates 2 can be moved towards the side away from or close to each other, thereby adjusting the distance between the two support plates 5. This device can adjust the distance between the two support plates 5 according to the specific length of the plate and the position where the plate is bent to fit the plate of appropriate specifications. When adjusted to the appropriate position, the plate to be bent is placed on the upper surface of the support plate 5. Since the second chute 1101 is provided on the upper surface of the support plate 5, and the limiting clamping plates 1102 are slidably installed on both sides of the upper surface of the support plate 5, the through groove 1103 is penetrated through the guide plate 8. Two second sliders 1104 are slidably installed inside the second chute 1101. The two second sliders 1104 are respectively connected to the two limiting clamping plates 1102, and the two second sliders 1104 are connected by the spring 1105. The two limiting clamping plates 1102 can play a role in positioning the two sides of the plate, making the plate placed on the support plate more accurately positioned without tilting. Due to the elasticity of the spring 1105, it can play a role in positioning the two limiting clamping plates 1102 and enable the limiting clamping plates 1102 to have a certain buffer, thereby being able to limit plates of different specifications and ensuring the stability of the plate. At this time, the output end of the first hydraulic cylinder 16 expands and contracts, enabling the guide plate 8 to move downward in the middle of the guide rod 7, thereby pressing the two guide plates 8 against the two ends of the plate respectively, thus playing a role in fixing the plate. At this time, the output end of the second hydraulic cylinder 404 expands and contracts. Since a groove 402 is provided at one end of the limiting plate 401 away from the positioning plate 2, a first rotating shaft 403 is rotatably installed between the inner walls on both sides of the groove 402, a second hydraulic cylinder 404 is fixedly installed on the side of the first rotating shaft 403, a second rotating shaft 406 is rotatably installed between the inner walls on both sides of the positioning clamping plate 405, and the output end of the second hydraulic cylinder 404 is arranged on the side of the second rotating shaft 406. When the output ends of the two second hydraulic cylinders 404 expand and contract, the two folding plates 6 can be driven to flip, enabling the two folding plates 6 to apply pressure to flip the two ends of the plate, thereby bending the plate. This device can bend the two ends of the plate simultaneously. This device can be adjusted according to the specifications of the plate and can bend the two ends of the plate simultaneously. This device is easy to operate and can position the plate to ensure the quality of bending. By the expansion and contraction of the output end of the first hydraulic cylinder 16, the guide plate 8 can move downward in the middle of the guide rod 7, thereby pressing the two guide plates 8 against the two ends of the plate respectively. When the two guide plates 8 move towards both sides between them, the sliding rod 18 can move towards both sides in the middle of the remote mounting sleeve rod 17.It will not hinder the movement of the guide plate 8.,

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
