Quick loading devices 14 are connected to the bottom of the horizontal boss of the steel rack 11 by threads. The quick loading devices comprise a first ejecting needle 141, a first triaxial cylinder 142, a second ejecting needle 143 and a second triaxial cylinder 144, each of the two triaxial cylinders is vertically mounted relative to an opening 145 in the steel rack. The first ejecting needle 141 and the second ejecting needle 143 are upward passed through the openings 145 in a partial view of FIG. 2. Bars are ejected from the top of the storage plate to the top of the loading rack 2 using inclined surfaces at the ends of the ejecting needles.

As shown in FIGs. 4 and 5, the front end of the top of the loading rack 2 is connected to a stopper 23 by bolts so as to realized the position limitation of bars; an i-steel mounting plate 2201 is welded to the middle of the loading rack, and the body of the ejecting mechanism 22 is mounted on the i-steel mounting plate 2201; a stepping motor 2205 can drive a leadscrew 2207 through a coupling and thus drive a sliding plate 2208 to horizontally move with the guiding of track slider modules 2202; the second ejecting needles 2204 are driven by the second triaxial cylinders 2203, and the ejecting range of the second ejecting needles 2204 is adjusted, such that only one bar is ejected at a time.

As shown in FIG. 6, the conveying table 3 comprises a channel steel body 35; a stepping motor 32 is arranged on one side of the channel steel body 35 close to the loading rack 2, the stepping motor 32 can drive rollers 31 to rotate, and then the rollers drive chain wheels 34 and chains 33 to rotate synchronously so that bars can be fed in the extending direction of the channel steel body 35 at a constant speed.

As shown in FIGs. 7-9, the blanking device 4 comprises a cutter 41 and a dividing mechanism 42. A feed opening of the dividing mechanism 42 is arranged opposite to the cutter 41. A handwheel 429 is adjusted to move a block 421 to a proper position. Bars are conveyed by the conveying table 3 to the cutter 41. After the bars are blocked by the block 421, a proximity sensor 422 receives a signal and trigger the cutter 41 to implement blanking.

A cylinder 428 drives a pushing plate 424 to push the cut bars to a first processing line 43. An ejecting cylinder set 426 and a pushing rod set 427 form a pair of cylinder-and-pushing rod modules coaxially mounted in the extending direction of the processing line in both the first processing line 43 and a second processing line 44. A cylinder mounted in the first processing line 43 drives a pushing rod to forward push bars in the first processing line 43. At this time the conveying table 3 forward conveys the bars again. After the bars are cut by the cutter 41, a cylinder 428 drives the pushing plate 424 to retract and brings the bars into the second processing line 44. Afterward, a cylinder of the ejecting cylinder set 426 located in the second processing line 44 drives a pushing rod of the pushing rod set 427 located in the second processing line to forward push the bars. The machine sets repeat the procedures in this sequence. Bars after the second bar in the processing lines are forward pushed by bars newly loaded into the processing lines.

The downward inclined track at the pit at the bottom of the guiding table 61 leads to a mold of the crosspiece press 7. When the bars are conveyed to the guiding table from the medium frequency heating pipes, the bars flow along the guiding table to a reversing table 621 in the middle, and then an electric revolving table 626 drives a revolving disc 625 by 90°, such that openings of the reversing table 621 are opposite to shifting rods 624. At this time the shifting rods 624 can be driven by a servo motor 623 to pass through the openings and shift the bars along the track at an end of the guiding table into the mold of the crosspiece press 7.

As shown in FIGs. 12-13, a general crosspiece press is employed as a crosspiece press 71; a mold at the bottom of the press is divided into two parts: a movable mold 72 on an inlet side and a fixed mold on the other side; the lower part of the movable mold 72 is connected to a piston rod of the cylinder 73. After the crosspiece press 71 completes one pressing, the cylinder 73 drives the movable mold to rise upward, and eject the finished anchor chain crosspiece from a discharge opening on the right side into a basket 74 to complete collection.
