Beneficial effect of the present invention is: novel structure, and hydraulic control is easy to operate, and product undercarriage is easily convenient; The application is provided with bottom knockout device, when U-shaped beam is just from the band liner plate bed die demoulding, just rolled jack-up by the multiple joists in bottom knockout device, and joist roll inside be provided with bearing can flexible rotating, therefore the U-shaped beam of finished product just can not can release frame from stripper plate easily by other instrument (as little round steel etc.), hang away with crane, it is easily convenient that this gimmickery achieves product undercarriage again; The U-shaped beam once suppressed by the upper and lower mould of band liner plate can ensure that dimensionally stable, quality are good, forming speed is fast; Due to the high-abrasive material plate of the replaceable different-thickness of the liner plate on upper and lower mould, therefore the gap of different in width can be formed between upper and lower mould, so just can process the blank of different-thickness, produce the U-shaped beam of varying strength, the U-shaped beam of different in width can also be processed; Both many specifications U-shaped beam product can just be produced by the different-thickness of the upper and lower mould liner plate of adjustment; Also beneficial is when after mould excessive wear, as long as change liner plate just can recover normal use, avoids whole set of die to scrap, saves use cost; Bending cylinder piston rod is connected with band liner plate mold by piston flange seat, and connect rigidity so strong, syndeton handling ease processing cost is few; Band liner plate bed die is connected with frame by L shape pressing plate, even if fixing threaded hole position exists relatively large deviation in such syndeton frame, band liner plate bed die can be fixed on tram, Joining Technology is ingenious; Upper and lower demoulding oil jar can ensure the demoulding of finished product fast and easy, solves finished product and is stuck in the problem of can not getting out on mould; Multiple bottom knockout oil cylinder is connected to stripper plate, and bottom U-shaped beam the U-shaped corbel be stuck in groove out by stripper plate holder, such whole piece U-shaped beam stress uniform shape does not change, and ensures that finished appearance quality is good; Likely first bottom knockout oil cylinder is started during stripping operation, the U-shaped beam of finished product is ejected together with band liner plate mold from band liner plate bed die, when such band liner plate mold continues to rise, some U-shaped beam likely can clamp band liner plate mold, as long as now start upper demoulding oil jar, its piston rod stretches out and U-shaped beam will be pushed from band liner plate mold, solves the upper modulus problem of folder easily; Before assist device, machine, platform can keep travelling stock or mobile finished product to operate easy and convenient; Blank be pressed in the bearing in assist device rolls light very flexibly; Before machine, the boosting drum sleeve of platform is contained in the Baltimore groove of rolling stand, and dismounting is convenient, is easy to safeguard; Can according to place, workshop situation, before using two cover machines, platform is placed in the two ends of frame, allows blank enter from platform before a machine, finished product from platform before another machine out, such continuous productive process, speed is faster; Screw blank centering device controls blank and enters after above band liner plate bed die, and the center line that must control blank before compacting is identical with the center line of mould, and the product size symmetry that this makes it possible to ensure to suppress out is qualified, yield rate is high; The regulating arm that the swing arm that moves to left in screw blank centering device is arranged can be used for inching, correct due to installation deviation between centralising device and frame, ensure blank center line to be moved to by the control of screw blank centering device to overlap with mold center line; The present invention support the use screw blank centering device can ensure mechanism allow in the blank of various width can accurate centering, work as long as shake handwheel just can complete centering, being particularly suitable for blank is not that very heavy manufacturer configures, and cost is also inexpensive; As long as this equipment one people can complete production operation under having crane to assist; Therefore equipment of the present invention can produce the U-shaped beam product of many specifications of different in width and different thickness of slab, can reach that quality is good, the demoulding easily, product undercarriage is convenient, yield rate is high, production efficiency is high, labour intensity is little, less with labour, the effect such as save production cost.
