Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, the present invention provides a bending device for high-speed guardrails, including a base plate 1 and a workbench 2. The workbench 2 is fixedly connected to the top of the base plate 1. A lower mold 3 is embedded in the top of the workbench 2. Support columns 4 are fixedly connected to the four corners of the top of the base plate 1. A top plate 5 is fixedly connected to the top of the support columns 4. Electric cylinders 6 are fixedly connected to the left and right sides of the top of the top of the top plate 5. An upper mold 7 is provided at the bottom of the top plate 5. The output end of the electric cylinder 6 passes through the top plate 5 and is fixedly connected to the top of the upper mold 7. An installation groove 8 is opened on the right side of the top of the workbench 2. A clamping mechanism 9 is fixedly connected to the right side of the workbench 2.

[0021] refer to Figure 1 and Figure 3 The clamping mechanism 9 includes a servo motor 91, which is fixedly connected to the right side of the worktable 2. The output end of the servo motor 91 passes through the worktable 2 and is fixedly connected to the drive gear 92. The surface of the drive gear 92 is meshed with a rack 93. There are two racks 93 arranged vertically. The outer side of the top of the rack 93 is fixedly connected to a clamping plate 94. The left side of the bottom of the clamping plate 94 is fixedly connected to a limit assembly 10.

[0022] As a technical optimization of this utility model, by setting a clamping mechanism 9, the servo motor 91 is fixed to the worktable 2, the output end of the servo motor 91 is fixed to the drive gear 92, the rack 93 is engaged with the drive gear 92, and the clamping plate 94 is fixed to the rack 93. The user starts the servo motor 91 to drive the drive gear 92 to rotate, and the drive gear 92 engages with the rack 93 to make the rack 93 move inward. The rack 93 drives the clamping plate 94 to clamp and fix the original material inside, so that the center point of the original material is fixed each time, ensuring the consistency of each pressing.

[0023] refer to Figure 2 and Figure 3 The limiting component 10 includes a limiting block 101, which is fixedly connected to the left side of the bottom of the clamping plate 94. A limiting groove 102 for use with the limiting block 101 is provided on the left side of the top of the workbench 2. The limiting block 101 and the limiting groove 102 are slidably connected.

[0024] As a technical optimization of this utility model, by setting a limiting component 10, the limiting block 101 is fixed to the clamping plate 94, and the limiting block 101 is made to slide into the limiting groove 102 of the worktable 2. The limiting block 101 and the limiting groove 102 restrict the clamping plate 94 to move more stably, thereby improving the structural stability of the entire device.

[0025] refer to Figure 3 An anti-slip pad 11 is fixedly connected to the inner side of the clamp 94.

[0026] As a technical optimization of this utility model, by setting an anti-slip pad 11, the anti-slip pad 11 is fixed to the clamping plate 94. The anti-slip pad 11 increases the friction between the original plate and the clamping plate 94, reduces the possibility of slippage during clamping, and improves the stability during clamping.

[0027] refer to Figure 1 An electric telescopic rod 12 is fixedly connected to the left side of the top of the workbench 2, and a moving block 13 is fixedly connected to the output end of the electric telescopic rod 12.

[0028] As a technical optimization of this utility model, by setting an electric telescopic rod 12 and a moving block 13, the electric telescopic rod 12 is fixed to the worktable 2, and the moving block 13 is fixed to the output end of the electric telescopic rod 12. By starting the electric telescopic rod 12, it drives the moving block 13 to move forward, so that the moving block 13 restricts and positions the raw material. After clamping is completed, the electric telescopic rod 12 is started again to drive the moving block 13 to retract, thereby realizing automatic positioning of the raw material and reducing the need for manual operation.

[0029] refer to Figure 1 A controller 14 is fixedly connected to the left side of the front of the base plate 1. The controller 14 is electrically connected to the electric cylinder 6, the servo motor 91 and the electric telescopic rod 12 through wires.

[0030] As a technical optimization of this utility model, by setting up a controller 14, the controller 14 is fixed to the base plate 1, and the controller 14 is electrically connected to the electric cylinder 6, the servo motor 91 and the electric telescopic rod 12 through wires. The user can centrally control all electric components through the controller 14, making the operation simpler and improving the work efficiency.

[0031] The working principle and usage process of this utility model are as follows: When in use, the user places the raw material to be bent on the workbench 2, and then starts the electric telescopic rod 12 through the controller 14 to drive the moving block 13 to move forward, so that the moving block 13 restricts and positions the raw material. Then, the servo motor 91 is started to drive the drive gear 92 to rotate. Then, the drive gear 92 meshes with the rack 93 to allow the rack 93 to move inward. The limit block 101 and the limit groove 102 restrict the clamping plate 94 to make its movement more stable. The rack 93 drives the clamping plate 94 to clamp and fix the raw material inside. The anti-slip pad 11 increases the friction between the raw material and the clamping plate 94. Then, the electric telescopic rod 12 is started to drive the moving block 13 to retract. Then, the electric cylinder 6 is started through the controller 14 to drive the upper mold 7 to move downward. The bending of the guardrail is completed by the cooperation of the upper mold 7 and the lower mold 3.

[0032] In summary, this high-speed guardrail bending device, by setting up a clamping mechanism 9, allows the user to place the original material to be bent on the workbench 2, restrict it by the moving block 13 of the electric telescopic rod 12, and then activate the clamping mechanism 9 through the controller 14 to clamp the material. Then, the electric telescopic rod 12 is activated to drive the moving block 13 to retract, and then the electric cylinder 6 is activated through the controller 14 to drive the upper die 7 to move downward. The bending of the guardrail is completed by the cooperation of the upper die 7 and the lower die 3. This solves the problem that the bending process usually requires manual positioning, which is not only inefficient but also makes it difficult to ensure the consistency and accuracy of the product.
