Description
The utility model relates to the machinery of rolled steel, the machinery that particularly relates to cold rolling building iron and make it reverse.In the machinery of the rolling reinforcing bar of prior art, adopt the method for hot rolling mostly, and the rolling reinforcing bar that comes out does not have helix-deformed.This milling train must possess the working condition of heating, and place, environment and working condition are had relatively high expectations, and is subject to many limitations during use.Even the milling train of cold rolling function is arranged, also all be to adopt the memorial archway formula structure of roll in the centre, change very difficulty of roll.
The purpose of this utility model is for avoiding above-mentioned the deficiencies in the prior art, has cold rolling and makes reinforcing bar produce helix-deformed and change roll cold rolling reinforcing bar milling train easily for people provide a kind of.
The utility model is achieved through the following technical solutions, design, make a kind of cold rolling reinforcing bar milling train that comprises power part, rolling and cold twisting portion, rolling portion comprises housing, upper and lower roll mandrel and eccentric bushing separately, one end of roll mandrel stretches out the housing antetheca, its bracketed part that stretches out is set with roll, and then there is leading chewing the side.Two eccentric bushings respectively have the bearing of two its weight of supporting, and bearing fixing is on housing antetheca and rear wall.Upper and lower roll mandrel is respectively by two bearings of front-end and back-end in separately be embedded in the eccentric bushing, drives upper and lower roll mandrel from the power of reduction box output through power transmission shaft, drives roll and rotates in opposite directions.The worm gear profile of tooth is arranged on the cambered surface of two eccentric bushing appearances, and with two sections worm engagings that direction is opposite on the adjusting rod, an end of adjusting rod stretches out the housing end face and handwheel is housed respectively for they.Cold twisting portion is between upper and lower roll, with respect to leading another side of chewing, comprise the base that is fixed on the housing antetheca, to be bolted to the cover plate on the base, be stuck in the guide that reverses between base and the cover plate, be installed in the roller that reverses in the guide, roller is bearing on the wall that reverses guide by the bearing at two ends.Reinforcing bar after roll intermediate rolling through cold twisting portion with its torsional deflection, because roll sheath is contained in the bracketed part of roll mandrel, so it is very convenient to change roll.
Further describe most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 be the utility model cold rolling reinforcing bar milling train just, vertical view.
Fig. 2 is that cutaway view is looked on the left side of described milling train.
Fig. 3 is the elevational cross-sectional view of described milling train.
Fig. 4 is the cold twisting portion front view of described milling train.
Fig. 5 is that cutaway view is looked on the cold twisting portion left side of described milling train.
From Fig. 1, Fig. 2, can find out, the cold rolling reinforcing bar milling train that comprises power part 1, rolling 2 and cold twisting portion 4, its rolling 2 comprises housing 21, upper and lower roll mandrel 23,24 and eccentric bushing separately 25,26, one end of roll mandrel 23,24 stretches out housing antetheca 211, its bracketed part that stretches out is set with roll 232,242, and the side then has leadingly chews 28.Reinforcing bar is chewed 28 and is entered roll 232,242 intermediate rollings distortion through leading, and roll mandrel 23,24 is sleeved in the eccentric bushing 25,26, can regulate the opening between the roll 232,242, the reinforcing bar of rolling different size.Roll 232,242 is sleeved on roll mandrel 23,24 and stretches out housing antetheca 211 bracketed part outward, and it is convenient that roll 232,242 is changed.
Can find out that from Fig. 2, Fig. 3 two eccentric bushings 25,26 respectively have the bearing 253,254 and 263,264 of two its weight of supporting, bearing 253,263 is fixed on the housing antetheca 211, and 254,264 on bearing is fixed on the rear wall 212.Upper and lower roll mandrel 23,24 is embedded in the eccentric bushing 25,26 by two bearings 233,234 and 243,244 of front-end and back-end in separately respectively, drive upper and lower roll mandrel 23,24 from the power of reduction box 12 outputs through power transmission shaft 22, drive roll 232,242 and rotate in opposite directions.Such structure makes eccentric bushing 25,26 can be bearing on the housing 21 and can freely rotate that 23,24 of roll mandrels are bearing in the eccentric bushing 25,26, also can freely rotate.Power drives upper and lower roll mandrel 23,24 by power transmission shaft 22 through gear train assembly, and the rotation in opposite directions of roll 232,242 helps to reduce resistance in the rolling reinforcing bar process.
As can be seen from Figure 3, on the cambered surface of two eccentric bushings, 25,26 appearances the worm gear profile of tooth is arranged, with opposite worm screw 295,296 engagements of two sections directions on the adjusting rod 29, an end of adjusting rod 29 stretches out housing 21 end faces and handwheel 297 is housed respectively for they.Rotate handwheel 297 and drive worm screw 295,296 rotations, by the worm gear on two eccentric bushings, 25, the 26 appearance cambered surfaces that are meshed with it, driving eccentric bushing 25,26 rotates, make the displacement of roll mandrel 23, the 24 generation vertical direction that are embedded in the eccentric bushing 25,26, regulate the opening between the roll 232,242, when reaching rolling products of different specifications, permanent center is constant, make rolling smoothly.
From Fig. 4, Fig. 5, can find out, cold twisting portion 4 is between upper and lower roll 232,242, with respect to leading 28 the another side of chewing, comprise the base 41 that is fixed on the housing antetheca 211, to be bolted to the cover plate 42 on the base 41, be stuck in and reverse guide 43 between base 41 and the cover plate 42, be installed in the roller 431 that reverses in the guide 43, roller 431 is bearing on the wall that reverses guide 43 by the bearing 433,434 at two ends.Reinforcing bar enters in the cold twisting guide 43 after rolling through upper and lower roll 232,242, produces torsional deflection under the effect of roller 431, by reversing the different angles of roller 431 in the guide 43, can make reinforcing bar produce different torsion effect.
In addition, the bearing 233,234,243 and 244 on the roll mandrel 23,24 is the special-purpose heavy rolling thrust bearings of steel rolling, and the bearing 253,254,263 and 264 on the eccentric bushing 25,26 is sliding bearings.Can bear and eliminate the axial force that produces in the rolling reinforcing bar process like this, avoid roll mandrel 23,24 to produce axial displacement.
The worm gear profile of tooth on the outer surface, garden of eccentric bushing 25,26 1 ends, with eccentric bushing (25), (26) can be one, also can overlap and load onto.Gap between like this can high-precision adjusting roll 232,242, and can reach the purpose of self-locking.
The two ends of the roller 431 of cold twisting portion 4 are the cylinders with diameter, and mid portion is the butt cone.Steel bar end is entered reverse when reversing in the guide 43 more unobstructed, can clamping stagnation.
Power part (1) adopts AC asynchronous motor, is powered by variable-frequency power sources.Can bringing onto load starting and constant-power speed regulation.
Owing to adopted above-mentioned technical scheme, make to the utlity model has cold rolled reinforcing bar and to make reinforcing bar produce torsional deflection, and roll change convenient, and the characteristics of saving the energy and material less demanding to place, environment and working condition, make things convenient for unit in charge of construction, improved production efficiency.
