A derusting shelling device is arranged before the rolling machine head box, and a stress-relieving device is arranged behind the speed reducer. The utility model can automatically and continuously complete procedures such as derusting shelling, multitrack rolling, rib mark rolling, stress relieving, etc., and has the advantages of small size, light weight, low cost, power consumption saving, and high productive efficiency.

Description

The Ribbed Bar roll mill

The utility model belongs to a kind of metal rolled machinery, and specifically the machinery of cold rolling small-sized screw-thread steel is the Ribbed Bar roll mill.

Existing small-sized Ribbed Bar is rolling to be needed earlier to make spiral what dividing progressively reroll behind the tube reducing through wire drawing die on many wire drawing machinees, production process Taoism is many, the per pass operation all will be equipped with corresponding motor, decelerator with a unit, for example existing a kind of Ribbed Bar rolling equipment needs more than ten unit of ten tons of tuples just can be linked to be production line, takies factory building 15m * 60m=900m ², up to a hundred kilowatts of installed capacitys, equipment is many, cost is expensive, power consumption is big, can not produce unstable product quality continuously.

The purpose of this utility model provides a kind of novel Ribbed Bar production equipment, make that its rust cleaning is peeled off, the rolling tube reducing of multiple tracks, rolling rib line and multiple working procedure such as eliminate stress be combined on the machine, make it to simplify working process, facility compact, volume is little, cost is low, power consumption is economized, and reaches multiple operation serialization, semi-automatic production.

The purpose of this utility model is to realize like this, the Ribbed Bar roll mill is by the rust cleaning peeling apparatus, rolling head box, decelerator, compositions such as the rolling cylinder and the device that eliminates stress, the rust cleaning shelling mechanism is installed before and after it is characterized in that on same support successively, rolling head box, decelerator, the reducer output shaft two ends are separately installed with left and right sides rolling cylinder, after the decelerator is mechanical type stress eliminating device and motor, fourth officer is housed in the rolling head box leans against the three-jaw self-centering chucks that front and back tank wall two or two is installed relatively, on every secondary three-jaw self-centering chuck, be equipped with three and roll the alternative former claw of tire, three 120 ° uniform rolling take turns to be contained in respectively by splined shaft roll on the tire, the three-wheel interlock, the rolling working face of wheel rim self-centering; Rolling 60 ° of the phase differences of taking turns on the two pairs of three-jaw self-centering chucks in front and back; The rust cleaning shelling mechanism divides two row's cross arrangements by 5-7 roller in the same plane, and array pitch is adjustable, and reinforcing bar is passed through from its wheel rim, be the serpentine distortion before penetrating rolling head box, peel off iron rust and oxide skin, do not make these impurity enter rolling head box, snap in rolling the wheel; Mechanical type eliminate stress device by in level and the vertical plane each by one group of 5-7 branch two arrange cross arrangements, roller that array pitch is adjustable is formed, with the Ribbed Bar after rolling from these roller surface through out-of-date in the repeatedly crooked twisting of serpentine of level and vertical direction, to eliminate rolling stress, regulate due tensile strength of reinforcing bar and percentage elongation.

The utility model since with rust cleaning peel off, the rolling tube reducing of multiple tracks, roll the rib trace, multiple working procedure such as eliminate stress all is combined on the unit, only drag with a motor and decelerator, realized the complete machine interlock, as long as once wear silk, adjust each mechanism's wheelspan parameter and can realize serialization, automation rolling mill practice, take up an area of only 8.75m ², heavy 2.74-3.85T, installed capacity 18.5kw has 40m ²Production site can be produced; Take turns three-wheel interlock because the utility model is rolling again, self-centering, so equipment is easy to adjust, long service life, rolled products quality are good, compared with prior art, its good effect is conspicuous.

Be that the utility model is described in further detail for embodiment below with the accompanying drawing.

Fig. 1 is a Ribbed Bar roll mill plan structure schematic diagram.

Fig. 2 is the A-A profile among Fig. 1.

Fig. 3 is the B-B profile among Fig. 2.

Fig. 4 is that part 3 and the rolling working face of 13 wheel rims are the flat wheel figure that rolls of straight cylinder

Fig. 5 rolls wheel figure for the curved circle of the rolling working face of part 12 wheel rims.

Fig. 6 is that part 4 wheel rim working faces are curved, and the wheel figure that rolls with ribbing of rib line is arranged at the bottom of the arc.

In Fig. 1-Fig. 6: 1 is rolling head box, and 2 are the rust cleaning shelling mechanism, and 3 are the flat wheel that rolls, 4 are the wheel that rolls with ribbing, and 5 is right rolling cylinder, and 6 is decelerator, 7 are the mechanical type device that eliminates stress, and 8 is tail wheel, and 9 is motor, 10 is belt, and 11 is left rolling cylinder, and 12 are the round wheel that rolls, 13 is to put down to roll wheel, and 14 is adjusting handle, and 15 is three-jaw self-centering chuck, 16 for rolling tire, and 17 is splined shaft, and 18 is support.

Rolling mill practice process of the present utility model is finished like this: motor 9 drags decelerator 6 by belt 10, the output shaft two ends of decelerator 6 drag respectively left rolling cylinder 11 and right rolling cylinder 5 on same axle towards equidirectional synchronous rotation, draw processed reinforcing bar walking.After peeling off iron rust and oxide skin, the wheel of rust cleaning shelling mechanism passes rolling head box from the arrow C introduction from the raw material of reinforcement rebar on the outer pay off rack of this machine, through rolling take turns the rolling tube reducing of 13 and 12 twice after around to left rolling cylinder 11 as the middle transition rolling, after walking around several circles on the left rolling cylinder 11, quote to the hole that rolling head box front arrow D points to and pass rolling head box for the second time, through rolling take turns 3 and 4 rolling tube reducings roll the rib trace after the transition rolling to the inboard rolling groove of right rolling cylinder 5, guide to mechanical type stress eliminating device 7 again, through mechanical type stress eliminating device 7 level and vertical direction repeatedly the serpentine distortion eliminate stress, adjust reinforcing bar suitable tensile strength and percentage elongation, guide the right rolling cylinder outside into as the finished product rolling through tail wheel 8 again, blanking, packing.So adjust as long as once wears silk, can realize that rust cleaning is peeled off, the rolling tube reducing of multiple tracks, rolling rib trace, eliminate stress, multiple working procedure such as rolling packing finishes automatically continuously, so high efficiency, good, the power consumptive province of quality.
