[0026] In order to increase the flexibility and continuity of the device, and improve the production effect of grid welding steel bars, such as Figure 1-3 As shown, a grid welding steel bar bending device described in the utility model comprises a frame 1, a guide assembly 4 and a manual control assembly 5, wherein a support platform 2 is connected to the frame 1 by bolts, electric push rods 3 are slidably connected to both sides of the support platform 2, and the output end of the electric push rod 3 is connected to the guide assembly 4 by bolts, and a manual control assembly 5 is arranged on the outer side of the frame 1;

[0027] The guide assembly 4 includes a telescopic sleeve 401, both ends of which are sleeved with a telescopic rod 402, an air cushion 403 is glued to the inner side of the telescopic rod 402 in the telescopic sleeve 401, and a return spring 404 is provided on the outer periphery of the telescopic rod 402 in the telescopic sleeve 401.

[0028] When in use, through the sliding connection of the telescopic sleeve 401 and the telescopic rod 402, the grid welded steel bars can be inserted into the gap to drive auxiliary displacement, thereby improving the automation effect of the device and the continuity of steel bar production and processing.

[0029] In order to improve the flexibility of device operation, for example, Figure 1 , Figure 4 As shown, the utility model also includes that the manual control component 5 includes a fixed seat 501, and the air outlet end of the fixed seat 501 is connected to the air cushion 403, an elastic body 502 is arranged on one side of the fixed seat 501, and a one-way valve 503 is arranged on the air inlet end of the fixed seat 501.

[0030] When in use, it is convenient to add a manual adjustment mechanism to improve the flexibility of the device. The air cushion 403 can be inflated by pressing, so as to adapt to different usage requirements and reduce the cost of using the device. A valve core is provided on the top of the fixed seat 501 on the outside of the frame 1.

[0031] For example, Figure 2 As shown, the utility model also includes that screw rods 201 are installed on both sides of the support platform 2 through bearings, and corresponding screw blocks 202 are arranged on the periphery of the screw rods 201, and the screw blocks 202 are connected to the electric push rod 3 through bolts.

[0032] When in use, the back of the support platform 2 is connected to the servo motor via bolts, and the servo motor is connected to the screw rod 201 via a driving shaft, so that the screw rod 201 and the screw block 202 can drive the guide assembly 4 to reciprocate horizontally.

[0033] For example, Figure 1 As shown, the utility model also includes that a pressing plate 6 is arranged on the top of the frame 1, the top of the frame 1 is connected to the second electric push rod 7 by bolts, and the output end of the second electric push rod 7 is connected to the pressing plate 6 by bolts.

[0038] Then the air cushion 403 is deflated, and the elastic driving force of the reset spring 404 is used to drive the telescopic rod 402 to retract into the telescopic sleeve 401 to complete the reset. At the same time, the second electric push rod 7 is turned on to drive the pressing plate 6 to press the workpiece to perform a limit fixing process. Then the hydraulic cylinder 8 drives the bending plate 9 to flip and bend the grid welded steel bars.
