The working process of the automatic welding device for manufacturing the split heads by utilizing the waste steel bars is as follows:

after the old building is dismantled, a large amount of old rebar can be recovered, usually by cutting, and is therefore generally short in length.

After the old steel bars are recycled, the old steel bars are classified into two types, namely U-shaped steel bar sections 51 and straight-bar steel bar sections, and are placed according to the respective sizes. In the subsequent process, a U-shaped steel bar section 51 and two straight bar steel bar sections (not shown) are welded into a split heads bar by the automatic welding device of the present invention.

Firstly, a plurality of U-shaped steel bar sections 51 are sequentially placed on a plurality of arc-shaped material placing notches 441 (see fig. 6 and 7) formed on the two side edges of the notch of the supporting frame 44. Then, a plurality of straight bar reinforcement sections (not shown) are respectively and sequentially placed into the storage barrels 72 on both sides in the transverse direction.

Then, according to the diameter of the placed U-shaped steel bar section 51, the longitudinal position of the positioning plate 15 is adjusted along the first dovetail groove 111; the height position of the material receiving lifting rod 12 is adjusted according to the length of the vertical rod of the placed U-shaped steel bar section 51; the transverse positions of the first 16 and second 22 transverse blocks are adjusted according to the length of the placed U-shaped steel bar section 51. The functions of adjusting the longitudinal position of the positioning plate 15, adjusting the height position of the material receiving lifting rod 12, and adjusting the transverse positions of the first transverse moving block 16 and the second transverse moving block 22 are described below.

As can be seen from the foregoing, the support bracket 44 is laterally closer to one side of the positioning plate 15. The discharging ejection cylinder 46 drives the material support frame 45 to ascend in a reciprocating mode: when the pair of sharp corners 451 move up to exceed the corresponding pair of arc-shaped material placing notches 441, the support edges 4511 of the pair of sharp corners 451 can support one u-shaped steel bar segment 51 together, and the cross-bar of the u-shaped steel bar segment 51 slides down to the lower adjacent arc-shaped material placing notches 441 along the support edges 4511, and the stop edges 4512 of the pair of sharp corners 451 can block the u-shaped steel bar segment 51 sliding down from the upper adjacent arc-shaped material placing notches 441 together (refer to fig. 9). Thus, the u-shaped steel bar section 51 in the arc-shaped material placing gap 441 located at the lowest position is lifted out and slides along the "flat edge" to the lower positioning clamping block 14. When the pair of sharp corners 451 move down to the reset position, the stopping edges 4512 no longer stop the U-shaped steel bars 51 sliding down from the adjacent upper-side arc-shaped material-placing notches 441, so that each U-shaped steel bar 51 moves down to the lower-side arc-shaped material-placing notches 441 (refer to fig. 10). That is, each U-shaped steel bar section 51 moves down to the adjacent arc-shaped material placing gap 441 on the lower side of the U-shaped steel bar section every time the material supporting frame 45 ascends and descends, so as to realize the one-by-one material discharging.

The U-shaped steel bar section 51 sliding along the flat edge to the lower positioning-clamping block 14 reaches the surface of the lower positioning-clamping block 14 first and does not fall into the lower positioning groove 141. Therefore, the piston rod of the pressing cylinder 632 drives the upper positioning clamp block 65 to move downwards. When the pushing edge 6531 of the pushing slider 653 contacts the surface of the lower positioning and clamping block 14, the compression spring disposed in the vertical accommodating groove 652 is compressed, and the pushing slider 653 is further pushed upward into a partial section of the vertical accommodating groove 652 disposed in the material suction electromagnet 64, that is, the length of a partial section of the lower end of the pushing slider 653 is reduced. Since the pushing edge 6531 is arc-shaped (see fig. 11 and 12), the pushing edge 6531 gradually converges upward from back to front. During the process of moving the upper positioning and clamping block 65 downward to fit the lower positioning and clamping block 14, the transverse rod section of the u-shaped reinforcing steel bar section 51 is pushed forward by the pushing edge 6531 and enters the lower positioning groove 141.

The cross-sectional dimensions of the lower positioning groove 141 and the upper positioning groove 651 are corresponding to the diameter of the transverse rod section of the U-shaped steel bar section 51, and the corresponding lower positioning-clamping block 14 and the upper positioning-clamping block 65 can be replaced according to the U-shaped steel bar sections 51 with different diameters.

As can be seen from the above, the support frame 44 is located closer to one side of the positioning plate 15 in the transverse direction, so that when a u-shaped steel bar section 51 enters the lower positioning groove 141, it is located closer to the "positioning side". When the transverse rod of the u-shaped steel bar section 51 enters the lower positioning groove 141, the positioning electromagnet 151 is energized to generate a weak magnetic force, so as to attract one vertical rod of the u-shaped steel bar section 51 to the positioning plate 15 (the attraction force is weak, the u-shaped steel bar section 51 can still slide relative to the positioning plate 15), at this time, the transverse positioning cylinder 153 is extended outward to push the vertical rod of the u-shaped steel bar section 51 attracted to the positioning plate 15 along the transverse direction for a set stroke until the bottom ends of the two vertical rod of the u-shaped steel bar section 51 are respectively located at the intersection of the clearance groove 31 and the welding positioning groove 32 respectively provided on the first transverse moving block 16 and the second transverse moving block 22, thereby completing the positioning (the positioned state is shown in fig. 2). The positioning state can be realized because the longitudinal position of the positioning plate 15 is adjusted along the first dovetail groove 111 according to the diameter of the placed U-shaped steel bar section 51 in the earlier stage; the height position of the material receiving lifting rod 12 is adjusted according to the length of the vertical rod of the placed U-shaped steel bar section 51; the transverse positions of the first 16 and second 22 transverse blocks are adjusted according to the length of the placed U-shaped steel bar section 51. "

After the positioning is completed, the piston rod of the compressing cylinder 632 further moves downward and maintains the pressure, so that the upper positioning groove 651 and the lower positioning groove 141 clamp the transverse rod of the u-shaped steel bar section 51 together.

Then, the pushing cylinders 73 located at the two lateral sides of the material receiving column 11 sequentially push the straight rod reinforcing steel bar segment (not shown) stored in the storage cylinder 72 at the lowest position into the welding positioning slots 32 (see fig. 13) respectively arranged on the first traverse block 16 and the second traverse block 22. Wherein, storage cylinder 72 sets up for the slope, and the direction of slope of storage cylinder 72 is followed to many straight-bar steel sections of its inside storage superpose in proper order, and under the action of gravity, has the motion trend of spontaneous slope inner wall gliding along storage cylinder 72. The principle that the pushing cylinder 73 pushes out the straight rod steel bar section stored in the storage cylinder 72 and located at the lowest position is as follows:

an extension spring (not shown) is connected to the bottom of the material pushing piece 732 and one end of the receiving groove 731 close to the overhanging direction. When the extension spring is in the reset state, the bottom section of the material pushing piece 732 is located in the receiving groove 731 and abuts against one end of the receiving groove 731 close to the extending direction, and the top section of the material pushing piece 732 is exposed out of the receiving groove 731 and penetrates through the material pushing groove 724. When the piston rod of the pushing cylinder 73 extends outward, the pushing piece 732 pushes the straight rod reinforcing steel bar section (not shown) located at the lowest position in the material storage cylinder 72 to move and push out from the front discharging hole 722 (and the rear discharging hole 723) so as to reach the welding positioning groove 32 respectively arranged on the first traverse block 16 and the second traverse block 22. During the pushing process of the pushing piece 732, the end of the pushing piece 732 in the receiving groove 731 is abutted by the side of the receiving groove 731 close to the extending direction (the extension spring is in the reset state, see fig. 16), so that the side of the end of the pushing piece 732 exposed out of the receiving groove 731 close to the extending direction can provide the pushing force.

After the pushing sheet 732 pushes the straight rod steel bar section (not shown) located at the lowest position in the material storage cylinder 72 out to the welding positioning grooves 32 respectively formed on the first traverse block 16 and the second traverse block 22, the pushing sheet 732 keeps a certain pushing force on the straight rod steel bar section (not shown), so that the advancing end of the straight rod steel bar section (not shown) abuts against the front side or the rear side of the two vertical rod sections of the U-shaped steel bar section 51.

The welding positioning slots 32 of the first traverse block 16 and the second traverse block 22 are respectively provided with welding electrodes 321 (see fig. 19), and when a straight bar reinforcement section (not shown) is located in a certain welding positioning slot 32, the straight bar reinforcement section (not shown) contacts with the welding electrodes 321. Then, the welding machine driving cylinder 83 on the corresponding side of the first traverse block 16 and the second traverse block 22 drives the welding slider 81 to slide inwards in the transverse direction, so that the welding heads 82 on the two transverse sides enter the clearance grooves 31 of the first traverse block 16 and the second traverse block 22 respectively and contact two vertical rod segments of the U-shaped steel bar segment 51 respectively. Then, the welding head 82 and the welding electrode 321 on one side are simultaneously energized, so that the welding head 82 on the side, the lower end of one vertical rod section of the U-shaped steel bar section 51, the advancing end of the straight rod steel bar section (not shown) and the welding electrode 321 form an energizing loop, and the energizing loop generates high heat between the lower end of the vertical rod section on the side and the advancing end of the straight rod steel bar section (not shown) with high current, so that the vertical rod section and the straight rod steel bar section are melted and welded together. And after the welding of the straight-bar reinforcing steel bar section on one side is finished, the welding of the straight-bar reinforcing steel bar section on the other side is carried out.

When pushing is completed, each straight rod steel bar segment (not shown) in the storage cylinder 72 slides down by a unit distance. After the welding is completed, the piston rod of the pushing cylinder 73 is retracted, and during the retracting process, one side of one end of the pushing sheet 732 exposed in the accommodating groove 731, which is close to the retracting direction, is abutted by the straight bar reinforcement section (not shown) at the lowest position in the material storage cylinder 72, and then the pushing sheet 732 swings to the horizontal state (see fig. 17, the tension spring is in the tension state), so that the pushing sheet 732 is not obstructed by the straight bar reinforcement section (not shown) at the lowest position in the material storage cylinder 72, and the piston rod of the pushing cylinder 73 can be retracted smoothly. When the piston rod of the pushing cylinder 73 is completely recovered, the pushing sheet 732 leaves the straight rod steel bar section (not shown) at the lowest position in the storage cylinder 72, and the pushing sheet 732 is reset under the action of the extension spring (as shown in fig. 16).

The lower ends of two vertical rod sections of the U-shaped steel bar section 51 are welded in sequence to form a stirrup. After the welding of a stirrup is completed, the suction electromagnet 64 is electrified to generate strong magnetic force, and then the piston rod of the pressing cylinder 632 moves upwards, so that the stirrup which is just welded is adsorbed to move upwards. Then, ejection of compact motor 62 drive cylinder seat 631 and compress tightly cylinder 632 and swing forward, at the wobbling in-process, inhale material electro-magnet 64 outage suddenly to get rid of this stirrup muscle to the receipts material department of base front side.
