Multi-station device for producing and welding prestressed positioning mesh of box girder

A multi-station device for producing and welding prestressed positioning mesh of box girder, comprising a straightener, a load conveyor, a long bar conveyor, a short bar conveyor, an assembly conveyor, a bender, an assembly and carry mechanism, a weld mechanism, and an unload mechanism,

• wherein steel bar raw materials are straightened and cut by the straightener, an outlet of the straightener is connected to an inlet of the load conveyor, long bars and short bars after straightening and cutting are sent to the load conveyor and then transported to the long bar conveyor and the short bar conveyor, respectively, the long bars are sent to the bender for bending or without bending, the long bars and the short bars pass through the assembly conveyor, the assembly and carry mechanism and the weld mechanism in sequence to complete assembly and weld treatment, and are unloaded by the unload mechanism,
• wherein a short bar push module is arranged on one side of the load conveyor, the short bar push module comprises a first two-stage cylinder assembly and a stop assembly,
• wherein the first two-stage cylinder assembly comprises a first two-stage cylinder, a first cylinder support frame for fixing the first two-stage cylinder, and a first push plate mounted at an end of the first two-stage cylinder, in an initial state, the first two-stage cylinder is located in a middle of an installation end of the first cylinder support frame, the short bars are configured to be pushed in different directions by extending or retracting two cylinders of the first two-stage cylinder, respectively,
• wherein the stop assembly comprises a sensor, a stop plate, and a stop drive mechanism, when the sensor detects the short bar, the stop drive mechanism lowers an entirety of the stop assembly, so that the stop plate prevents the short bar from moving forward, and then the first two-stage cylinder pushes the short bar to load;
• when the sensor detects the long bar, the stop drive mechanism raises the entirety of the stop assembly, so that the stop plate rises, and the long bar continue to be conveyed forward with the load conveyor.
