Described welder is steel band laser-beam welding machine.
Described decoiling equipment is wind off to put down for useless time to use material loading ground roll, and described material loading ground roll is a pair.
Specific embodiment is as follows:
1) first by core/secondary rolling in decoiling equipment of giving up, and process drives flat machine and cradle causes the second crosscutting shear;
2) core/useless volume unqualified thickness lattice part carries out cutting to length in the second crosscutting shear, and defective section is sheared rejecting, and thickness right rail to be delivered to before welder etc. to be welded;
3) stock roll is caused the first crosscutting shear after uncoiler, guide board platform, three rollers aligning pinch rolls steel band head is excised simultaneously, then to deliver to before welder etc. to be welded;
4) before welding machine, the steel band of welder both sides is respectively cut partial application, carry out centering with aligning vertical roll simultaneously, and weld;
5) weld complete, stock roll uncoiler main shaft reverse, core steel band collects while packing up by stock roll, last volume.
Compared with prior art, the beneficial effect produced is patent of the present invention:
(1), core can be opened and flat weld function with core and realize on a production line, automaticity is high, the problem that solution production efficiency is low;
(2) be wound on the stock roll uncoiler on right side after, core can being carried out leveling, realize regular object, while realizing core recycling, core thickness transitions section part is carried out out flat, become steel scrap and can realize increment into opening plate realizes recycling;
(3), adapt to while core, also can involve in row uncoiling cutting work for useless time, core and wind off volume function useless time and unite two into one, realize core recycling and waster utilizes functional unification, raising unit adaptive capacity and utilization ratio.
Accompanying drawing explanation
Fig. 1 is the layout of production line of the present invention;
Detailed description of the invention
As shown in Figure 1,
A kind of core and waster coil of strip are integrated and are utilized production line, and comprise the welder 1 occuping centre position, welder 1 wherein adopts steel band laser-beam welding machine, carries hydraulic shear in the left and right sides of laser-beam welding machine.For the welding between two steel band horizontal interfaces, it is prior art equipment.
The first aligning vertical roll 11, first crosscutting shear 12, second aligning vertical roll 13, three roller aligning pinch roll 14, swing guide pallet 15 and the stock roll uncoiler 16 set gradually from inside to outside from welder 1 side, stock roll uncoiler 16 wherein has the dual-use function of uncoiling and rolling by rotating.Aligning vertical roll wherein, for ensureing (relative rolling direction) centering before and after edger roll and eliminating edger roll memorial archway gap, improves the milled sheet shape of vertical miller and reduces edge rolling sideslip, is a kind of conventional equipment.Three roller aligning pinch rolls 14 its role is to clamp band steel, guide and guarantee its direct of travel, and carry out carrying out preliminary aligning to steel band, are also a kind of conventional equipments.In addition, crosscutting shear, swing guide pallet and stock roll uncoiler are common equipments, no longer introduce.
