heating for the first time: the mechanical arm clamps the drill rod from the axial positioning device of the material storing and stirring device 1 and transfers the drill rod to the V-shaped bracket 308 of the loading frame, and the two V-shaped brackets 308 provide two support positions for the drill rod; the dual-output-shaft speed reduction motor device 311 drives the transmission shaft and the second bevel gear 303 to rotate, the second bevel gear 303 is meshed with the Y-direction bevel rack 304 to drive the moving support 302 to move along the second Y-direction guide rail 312, and the end part of the drill rod enters the heating furnace 305 to be heated for the first time.

And (3) heating for the second time: the movable support 302 drives the heating furnace 305 to withdraw, and the mechanical arm transfers the drill rod from the V-shaped support 308 to a loading frame corresponding to the front of the second heating furnace 305 (for clarity, the loading frame positioned in front of the heating furnace 305 during the second heating is omitted in fig. 11); similarly, the moving frame 302 drives the heating furnace 305 to advance, the drill rod enters the furnace from the furnace inlet 306 to perform a second heating, and after the heating is completed, the moving frame 302 drives the heating furnace 305 to exit again.

In the above embodiment, as shown in fig. 1, the drill rod thickening feeder 4 includes a Y-direction conveying mechanism and a Z-direction lifting mechanism for conveying the end of the drill rod into the forging press 5 in the Y direction at a proper height position (aligned with the inlet center position of the quasi-forging press 5).

Specifically, in the working process of this embodiment, four sets of manipulators are equidistantly distributed, can realize four simultaneously and snatch: a loading frame for grabbing the drill rod from the axial positioning device of the storing and stirring device 1 to the first heating furnace 305 of the heating device 3; grabbing drill rods from the rack of the first furnace 305 to the rack of the second furnace 305; grabbing drill rods from a loading frame of the second heating furnace 305 to a drill rod thickening and feeding device 4; and (4) grabbing the drill rods from the drill rod thickening and feeding device 4 to a storage rack (not shown in the figure) of a subsequent station. The drill rod is circulated in a reciprocating way from the material storing and stirring device 1 to the heating device 3, then to the drill rod thickening and feeding device 4, and finally to the continuous operation of discharging and the synchronous operation of all the working procedures.

In the present application, "X", "Y" and "Z" may refer to the directions of coordinate axes identified in the drawings. The names of the components in the directions of "X", "Y" and "Z" represent a part of the structure of the component moving in the corresponding direction or a part of the structure of the component moving in the corresponding direction when the component is implemented specifically, and the names are similar to the forms of "first" and "second", which are only used for conveniently distinguishing similar components during the description, and other meanings which are not explicitly shown or implied form the limitation of the application.
