The electric push rod 17 can drive the movable plate 10 to extend and retract, thereby facilitating the removal of the steel grating welded.

[0034] In the technical scheme of the utility model, as shown, Figures 1-3 As shown, the workbench 1 is fixedly installed with a controller 12, and the controller 12 is electrically connected with the first reciprocating motor 13, the second reciprocating motor 26, the driving motor 15, the electric push rod 17, the hydraulic rod 23 and the hot pressure welding body 24. The controller 12 can facilitate the operation of the first reciprocating motor 13, the second reciprocating motor 26, the driving motor 15, the electric push rod 17, the hydraulic rod 23 and the hot pressure welding body 24.

[0035] In use, first, the staff can ensure that all parts of the welding device are in normal state, including the workbench 1, the fixed block 2, the first screw rod 3, the first guide rod 4, the first threaded block 5, the convex plate 6, the movable plate 10, the guide wheel 11, etc. Check whether the external equipment power supply and the controller 12 are connected normally, and ensure that all motors, hydraulic rods 23 and hot pressure welding bodies 24 can work normally.

[0036] The worker puts the flat steel into the placing hole 7 inside the convex plate 6 which is connected to the workbench 1 through the first threaded block 5 to ensure the stability of the flat steel during movement. The first reciprocating motor 13 is started to drive the first lead screw 3 to rotate. Since the first lead screw 3 is threaded through a first threaded block 5, and the other first threaded block 5 is supported by the first guide rod 4, the two first threaded blocks 5 and the convex plate 6 on them will move synchronously. With the movement of the convex plate 6, the flat steel is guided to the placing groove 8 position on the workbench 1. Since the distance between the convex plate 6 and the workbench 1 is less than the height of the flat steel, when the flat steel reaches above the placing groove 8, it will drop due to gravity to a state of not contacting the convex plate 6. The convex plate 6 continues to move to accurately place the flat steel inside it in the placing groove 8, filling the entire slot.

[0037] The external conveying equipment such as the conveying belt conveys the cross bar into the guide groove in each set of guide wheels 11, and then above the flat steel. The guide wheels 11 on the movable plate 10 play a guiding and pressing role to ensure that the cross bar can be accurately placed on the flat steel.

[0038] If necessary, the driving motor 15 can be started to drive the plurality of guide wheels 11 to rotate through the pulley 14 and the belt transmission, facilitating the tail end of the cross bar to continue to be conveyed to the working position under the cooperation of each set of guide wheels 11.

[0039] The second reciprocating motor 26 is started to drive the second lead screw 20 to rotate, and in turn drive the U-shaped frame 22 and the hydraulic rod 23 and the hot pressure welding body 24 on it to move along the workbench 1 to the welding position. The extension length of the hydraulic rod 23 is adjusted as needed to make the hot pressure welding body 24 tightly contact with the contact surface of the flat steel and the cross bar. The hot pressure welding body 24 is started for welding operation. The controller 12 can set parameters such as welding temperature, time and pressure. The hot pressure welding body 24 is usually equipped with heating elements such as resistance wire, electric heating tube or electromagnetic induction heater inside for providing the heat required for welding. These heating devices can quickly heat to the set temperature and maintain stable heating state to ensure sufficient melting and bonding of the welded joint.

[0040] After welding is completed, the electric push rod 17 is started to drive the movable plate 10 to move sideways, thereby facilitating the worker to take out the welded steel grating from the workbench 1. After the steel grating is taken out, the above steps are repeated for the next batch of processing.

[0041] Through the above working process, the welding device can efficiently complete the processing task of the steel grating, reduce the workload of the worker and improve the production efficiency.
