Abstract

The utility model discloses a rolled device for producing cold-rolling thread reinforcing steel, comprising a machine base, a roll base, and two sets of roll groups arranging in a 'Y' shape. The included angle between the two sets of rolls is 60 DEG, the included angle between the rolls in each set of rolls is 120 DEG, all rollers are driven, and distances between rolls can be regulated by housing screws. The device is especially suitable for the production of the thread reinforcing steel whose diameter is below 10 mm, and the products of mechanical property can reach the criteria specified index of west German DIN 488.

Description

Rolled device for cold -rolling thread reinforcing steel

The utility model belongs to a kind of mold of producing cold-rolled threaded reinforcing steel, is specially adapted to produce the cold-rolled threaded reinforcing steel of diameter below 10 millimeters.

At present, a large amount of employing low-carbon (LC) hot rolling dish circles and cold drawn mild steel wire are that raw material is used for armored concrete and medium and small prestressed component in the building trade, percentage elongation deficiency because of raw material, little with concrete bond stress, reduced the safety coefficient of member, reduced the bulk strength and the shock resistance of member, the member brittle failure has taken place easily.And cold-rolled threaded reinforcing steel since have tensile property height, plasticity good, with characteristics such as grip of concrete is big, so can improve integral rigidity, bulk strength and the degree of safety of concrete component.Chinese patent CN2030513U discloses a kind of " Y type cold drawing and rolling screw steel wire machine ", this equipment is made up of the roll of three Y-shaped layouts, its nominal angle is 120 °, the roll shop building distance is to realize by the engagement of adjusting two conical gears, other adjustment means not being done being described in detail, because this body structure of gear must have certain interval, is feasible as transferring power, but it as the means of adjusting distance, is remained in some problems aspect precision.In addition, this equipment influences the service life of entire equipment because bearing does not have sealing device.

The purpose of this utility model overcomes the shortcoming of above-mentioned prior art exactly, obtain a kind of pass reasonable in design, can accurately adjust the long cold-rolled threaded reinforcing steel process units of product size, service life, this device and wire drawing machine are used, and are particularly useful for the technological transformation to hot candied factory.

For achieving the above object, the utility model is achieved in that the roll stacks that adopts two groups of Y-shaped layouts, and wherein each roll shop building angle is 120 °, and two groups of roll shop building angles are 60 °.

For achieving the above object, the utility model is so further realization: this device also comprises casing and roll, roll is by roll shaft and be enclosed within its outside collars and form, roll shaft is supported by rolling bearing, bearing places among stifle and the saturating lid sealing, bearing joins with housing screw by U-shaped slide block and adjustment distance, and the outer surface of collars is shaped on thread groove.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the elevation of the utility model roll milling apparatus.

Fig. 2 be among Fig. 1 A-A to cutaway view.

Among Fig. 1, support 1 is installed on the Equipment Foundations, and casing 2 is connected with bolt with support, roll axle bed 3 and be fixed on the casing, there is guide groove on the roller base two sides, and first group of roll 4 is housed in the guide groove, it is 60 ° that 11, two groups of roll shop building angles of second group of roll are housed in the another side guide groove; Three rolls are arranged in every group of roll, 120 ° of roll shop building angles, 120～150 millimeters of roller diameters, wide 10～30 millimeters.

Among Fig. 2, roll is made up of collars 5 and roll shaft 6, collars is sleeved on the roll shaft with the method for interference fit, the roll shaft two ends are supported by rolling bearing, it is passive that all rolls are, bearing is by 8 supportings of U-shaped slide block, and airtight space is formed by stifle 9 and saturating lid 10 in the bearing two ends, and bearing is worked under good lubricating condition; Utilize housing screw 7 to adjust the relative position of roll shop building, so that change product size, the collars outer surface is shaped on flight.

The utility model designs in existing hot candied technical foundation, uses the wire drawing machine traction steel wire, is particularly suitable for hot candied factory is undergone technological transformation, and small investment, instant effect are invested 20,000 yuan of production capacity that can form 1000 ton/years.

Because the utility model adopted two groups of Y shape rolls to be used,--triangle--the circular pass series that meets circle, pressure processing mechanism is correct, and is rational in infrastructure, and the high speed that can realize 10 meter per seconds is pulled out and is rolled.

The utility model places casing with whole device, and except the stationary roll seat, also salable cooling-lubricant prevents from splashing, and recycles in order to cooling and lubricating. The bearing of this device is to work in confined conditions, and machine life is prolonged.

The utility model is to adopt housing screw to adjust the relative position of roll shop building, and to compare degree of regulation higher with conical gear.

Utilize this roll milling apparatus can successfully produce the cold-rolled threaded reinforcing steel that the surface has three ribs, every cover roll can be produced 200 tons and go up steel, and its mechanical performance can reach China's every index of the West Germany DIN488 prescribed by standard of employing at present.

Claims

1, a kind of cold-rolled threaded reinforcing steel roll milling apparatus, the support of this device is installed on the Equipment Foundations, casing links to each other with support, roller base is fixed on the casing, the roll stacks of Y-shaped layout is housed on the roller base, wherein each roll shop building angle is 120 °, it is characterized in that: this device comprises two groups of Y-shaped roll stacks, and two groups of roll shop building angles are 60 °.

2, device according to claim 1, the roll that it is characterized in that this device is by roll shaft and be enclosed within its outside collars and form, roll shaft is supported by rolling bearing, bearing places among stifle and the saturating lid sealing, bearing joins with housing screw by U-shaped slide block and adjustment distance, and the outer surface of collars is shaped on thread groove.
