[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the specific embodiments and corresponding drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0021] like Figure 1 As shown, the double-station vehicle-mounted tube blank laser head and tail double centering device of the utility model comprises a conveying roller 1, two groups of transfer assemblies 2, a material shifting assembly 3, a centering assembly 4 and a punching machine entrance table 5. The two groups of transfer assemblies 2 are arranged between the conveying roller 1 and the punching machine entrance table 5, and are used to alternately convey the tube blanks to the punching machine entrance table 5. The material shifting assembly 3 is arranged in the middle of the upper and lower ends of the transfer assembly 2, and is used to load and unload the tube blanks. The centering assembly 4 is arranged at the left and right ends of the transfer assembly 2, and is used to detect the center points of the two ends of the tube blank and punch the centering holes, wherein:

[0022] The transfer assembly 2 includes a transfer vehicle 21, a transfer vehicle driving device 22 and a transfer vehicle track 23. The transfer vehicle track 23 is symmetrically arranged between the conveying roller 1 and the punching machine entrance platform 5. The transfer vehicle 21 is movably arranged on the transfer vehicle track 23. The transfer vehicle driving device 22 is arranged in the middle of the transfer vehicle 21 to provide driving force for the transfer vehicle 21, so that the transfer vehicle 21 is driven by the transfer vehicle driving device 22 to move on the transfer vehicle track 23, and travel back and forth between the conveying roller 1 and the punching machine entrance platform 5 to continuously provide pipe blanks to the punching machine entrance platform 5.

[0023] Further, in the double-station vehicle-mounted tube blank laser head-tail double centering device of the utility model, the material-dividing assembly 3 includes a first material-dividing plate 31 and a second material-dividing plate 32, the first material-dividing plate 31 is arranged at the top of the transfer vehicle track 23 and is parallel to the conveying roller 1, and the second material-dividing plate 32 is arranged at the bottom of the transfer vehicle track 23 and is parallel to the punching machine entrance table 5, wherein the first material-dividing plate 31 and the second material-dividing plate 32 are both rotating cross-shaped structures, so that when the first material-dividing plate 31 rotates, the tube blank conveyed on the conveying roller 1 is dialed into the transfer vehicle 21, and when the second material-dividing plate 32 rotates, the tube blank in the transfer vehicle 21 is dialed into the punching machine entrance table 5;

[0024] The first material-diverting plate 31 and the second material-diverting plate 32 can be structures such as flaps, star wheels or material-diverting hooks.

[0025] Furthermore, in the double-station vehicle-mounted tube blank laser head and tail dual centering device of the utility model, the centering assembly 4 includes a head centering device 41 and a tail centering device 42, and the head centering device 41 and the tail centering device 42 are symmetrically arranged at the left and right ends of the transfer vehicle 21, and the head centering device 41 and the tail centering device 42 can be adjusted according to the length of the tube blank, wherein the head centering device 41 and the tail centering device 42 are both laser generating devices, and the size of the tube blank is measured by laser during centering, and the center point of the tube blank is determined, and the laser is emitted to punch the center point at the same time, thereby effectively improving the perforation stability of the tube blank, improving the uniformity of the wall thickness of the end of the tube blank, and improving the yield rate.

[0026] Furthermore, in the double-station vehicle-mounted tube blank laser head and tail double centering device of the present utility model, both the left and right ends of the transfer vehicle 21 are through structures, and the centers of the head centering device 41 and the tail centering device 42 are coaxial. Therefore, after the tube blank enters the transfer vehicle 21, during the movement of the tube blank, both ends of the tube blank are centered simultaneously, effectively avoiding the temperature drop of the tube blank caused by too long centering operation;

[0027] A fixing device is further arranged in the middle of the transfer vehicle 21. When the tube blank enters the transfer vehicle 21, the fixing device locks itself to fix the tube blank, and unlocks when the second stock pushing plate 32 touches the fixing device.

[0028] Specifically, after the tube blank is heated qualified in the heating furnace, it is conveyed above one set of transfer components 2 by the conveying roller 1. After the transfer vehicle 21 is in place, the first stock pushing plate 31 pushes the tube blank into the transfer vehicle 21. The transfer vehicle driving device 22 drives the transfer vehicle 21 to move along the transfer vehicle track 23, and transports the tube blank to the entrance table 5 of the piercing mill. During the transportation, the transfer vehicle 21 fixes the tube blank. At this time, after the centering component 4 detects the incoming material signal, the centering component 4 reaches the ready state, finds the center according to the size of the incoming material, and the head centering device 41 and the tail centering device 42 simultaneously emit lasers to punch holes in the head and tail of the tube blank. The second stock pushing plate 32 pushes the tube blank from the transfer vehicle 21 to the entrance table 5 of the piercing mill, and then quickly returns to the position of the first stock pushing plate 31 to wait for receiving the material. At the same time, the conveying roller 1 conveys the tube blank above the other set of transfer components 2, and repeats the above process to transfer the tube blank to the entrance table 5 of the piercing mill, so that the two sets of transfer components 2 alternately transfer the tube blank, effectively improving the working efficiency.

[0029] In summary, compared with the prior art, the double-station vehicle-mounted tube blank laser head and tail double centering device of the present utility model has the following advantages and beneficial effects:

[0030] The structure of the present utility model is simple and the cost is low. Through the setting of two sets of transfer components, the double-station alternate transfer of the tube blank can be realized, reducing the waiting time of the piercing mill for materials, improving the production efficiency. By using the head and tail double centering, the piercing stability is ensured, the piercing quality and the wall thickness uniformity of the steel pipe are improved, the probability of rolling jam accidents is reduced, and the centering of the tube blank is completed while the tube blank is moving, reducing the temperature drop of the tube blank.
