Abstract
The utility model relates to a cold rolling machine for manufacturing cold rolling screw steel bars, mainly comprising a horizontal two-roller machine which arranged on an underframe, a vertical two-roller machine and a gear transmission mechanism which is used for controlling the two two-roller machines to work synchronously. The two horizontal shafts of the horizontal two-roller machine, the two horizontal shafts of the vertical two-roller machine, the two vertical shafts of the horizontal two-roller machine and the two vertical shafts of the vertical two-roller machine are arranged on the shaft frame on the underframe; the two smooth rollers of the two horizontal shafts and the two profiled rollers the two vertical shafts are staggered into angles which are 90 DEG. The utility model has the advantages that raw material does not needs dragging at working; phenomenon of longitudinal ribs does not occur; higher elongation of the raw material can be maintained; the utility model is especially suitable for producing cold rolling screw steel bars with a large size.
Description
The utility model relates to a kind of special equipment that spiral is used of making, and particularly a kind ofly makes the cold-rolling mill that external form has double crescent cross rib spiral.
At present, the spiral that China produces mostly is hot rolling, its intensity of the spiral of this kind hot rolling is on the low side, and in the world, especially the spiral of Germany's production all is cold rolling, this cold rolled reinforcing bar had both had the high strength of cold-drawn low-carbon (LC) reinforcing bar, had the good advantage of bond stress between deformed sections reinforcing bar and the concrete again, was the new type steel of building trade extensive uses such as airport, bridge, dam, house.The bond stress that these steel are used between the armored concrete improves more than 2.6 times.This shows, use above-mentioned cold-rolled threaded reinforcing steel to have remarkable economic efficiency.China also has a small part manufacturer to begin to produce as a trial cold-rolled threaded reinforcing steel at present, its production method is drawing---rolling-type, promptly with drawing machine tractive (doing power) in front, the cross rib of roll extrusion crescent in the above then, the colored roller of roll extrusion this moment also is passive, though the chill performance of spiral of producing with this method is good, but percentage elongation reduces (cold brittleness is big), circularity is poor simultaneously, sometimes have vertical rib, particularly this kind method is difficult to produce the spiral (as the spiral of φ 7-φ 12) of big specification.
In view of the foregoing, the purpose of this utility model provides the big specification spiral of a kind of energy production and can keep the cold-rolling mill of raw material than high-elongation.
The purpose of this utility model is achieved in that it comprises the horizontal twin-roll machine that is located on the underframe and the vertical gear drive that works asynchronously with vertical twin-roll machine of twin-roll machine and the horizontal twin-roll machine of control; In the horizontal twin-roll machine two trunnion axis and vertically in the twin-roll machine two vertical axes place on the pedestal that is located on the underframe, be provided with a smooth roll on two trunnion axis respectively, be provided with a colored roller on two vertical axes respectively, the flower roller is staggered into an angle of 90 degrees on smooth roll on the trunnion axis and the vertical axes; Two trunnion axis and two vertical axes one ends are provided with travelling gear respectively, two travelling gears on two trunnion axis are meshed through two Jie's gears, one of them travelling gear also is meshed with main drive gear on the horizontal final drive shaft through another Jie's gear, horizontal final drive shaft two ends are respectively equipped with the bevel gear that can make the bel-drivenn belt pulley and be meshed with bevel gear on the vertical final drive shaft with motor, one of them is meshed travelling gear on two vertical axes with main drive gear on the vertical final drive shaft, and another is meshed with main drive gear through Jie's gear.The horizontal final drive shaft rotation of motor drives during work, and drive two horizontal rotational shaft thus, drive vertical final drive shaft and the rotation of two vertical axes by two meshed bevel gears on horizontal final drive shaft and the vertical driving shaft simultaneously, make smooth roll and the rotation synchronously of the colored roller on two vertical axes on two trunnion axis, when the reinforcing bar of certain specification is imported, two smooth roll frictionallies are nipped material, and carry out rolling, at this moment material enters again in the colored roller of phase difference 90 degree and carries out rolling once more, makes it to shut out the spiral that external form has double crescent cross rib.
The utility model has the advantages that: two smooth rolls and two colored rollers of being provided with respectively in horizontal twin-roll machine and the vertical twin-roll machine are initiatively roll, raw material is without tractive during work, kept the higher percentage elongation of raw material, be shaped simultaneously, the circularity height, vertical rib do not occur, be particularly suitable for producing the spiral of big specification.In addition, without guide plate and guide pin bushing, both simplified the structure between horizontal twin-roll machine and the vertical twin-roll machine, and saved parts again, and do not go out the jam phenomenon.
Detail of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the B of Fig. 1 is to view.
Fig. 3 is that the A of Fig. 1 is to view.
With reference to the accompanying drawings, the utility model mainly by underframe, horizontal twin-roll machine, vertically twin-roll machine and control horizontal twin-roll machine and vertically the gear drive of twin-roll machine synchronous working form.Two trunnion axis 6 and two vertical axes 5 in horizontal twin-roll machine and the vertical twin-roll machine place on the pedestal set on the underframe 1.For the ease of maintenance, this pedestal can be divided into horizontal pedestal 3 and vertical pedestal 4, and both are connected by bolt 23.Two trunnion axis 6 and two vertical axes 5 be placed in horizontal pedestal 3 and vertically pedestal 4 with eccentric bushing 19 on, two smooth rolls 10 and two colored rollers 8 are placed in by resilient sleeve 9 on two trunnion axis 6 and two vertical axes 5, and smooth roll and flower roller are staggered into an angle of 90 degrees, the effect of resilient sleeve 9 is assurance smooth rolls and spends roller not produce radially with axle and rock, two trunnion axis 6 and two vertical axes 5 outer ends are arranged with two travelling gears 21 and 18, two travelling gears 21 are by two Jie's gears 12,11 are meshed, wherein a travelling gear 21 is meshed with main drive gear 13 on the horizontal final drive shaft by Jie's gear 20, two ends have bevel gear 14 and belt pulley 22 respectively on the horizontal final drive shaft, this bevel gear 14 is meshed with bevel gear 15 on being located at vertical final drive shaft, belt pulley 22 and the motor 2 belt crop rotation belt transmission of being with decelerator, two vertical axes 5 outer ends with two travelling gears 18, master gear 16 on one of them direct and vertical final drive shaft is meshed, and another is meshed with master gear 16 through Jie's gear 17.Motor reducer 2 drive belt pulleys 22 and coaxial main drive gear 13, bevel gear 14 during work, because the bevel gear 15 on the vertical final drive shaft is meshed with the bevel gear 14 on the horizontal final drive shaft, make it to drive vertical final drive shaft and on main drive gear 16, drive two smooth rolls 10 on two trunnion axis 6 and two colored rollers 8 on two vertical axes 5 rotate synchronously by Jie's gear 12,11 and 17.When as two smooth rolls 10 of reinforcing bar from two trunnion axis of certain specification, penetrating like this, the smooth roll frictionally is nipped reinforcing bar, and carry out rolling, be sent in the colored roller 8 with smooth roll phase difference 90 degree rolling once more then, and by passing in the cover 24 that connects material, promptly make profile and have two row's crescent cross rib and this cross rib and the angled cold-rolled threaded reinforcing steels of axis, if the colored roller on two vertical axes 5 also is replaced by smooth roll, then this cold-rolling mill can be used as the cold-rolling equipment of a calibration bar diameter.
