The roller machine head has the beneficial effects of being applicable to the condition that wire rod steel bars are used as rolled blank, steel bars enter the roller machine head along the center of the roller machine head based on a certain speed, and rolling bolts of infinite length can be rolled and can be cut off based on a required fixed length, thus solving the problems that the length of the bolts is limited in the production process, realizing stub bar-free online production and achieving the aims of saving the labor force and not causing stub bar loss in the production process.
Description
Technical field
What the present invention relates to is bolt cold-rolling mill, particularly be a kind of roller machine head of bolt cold-rolling mill.
Background technology
At present, the structure of the screw rod cold-rolling mill of prior art comprises: be mutually three screw rod rolls of 120 degree, wherein two is the active roll, is fixed on the head framework, and said two active rolls connect the output shaft of Hooks coupling universal coupling and reducing gear respectively; Another is an idle roll, can radially move, and through the trave lling girder of adjustment idle roll, adapts to the screw rod of rolling different-diameter.The process of the rolling screw rod of screw rod cold-rolling mill is: metal bar had both prolonged self axis rotation under the roll roll extrusion, prolong the axis reach again, accomplished the rolling of screw rod.
There is following defective in the screw rod cold-rolling mill of above-mentioned prior art:
The blank that market sale is used for rolling screw rod is long metal bar; The bar of longer dimension is easy to occur bending and deformation owing to action of centrifugal force when rotating; At present can only production length at 6 meters with interior bolt; Therefore the production of longer size bolt is owing to the rolling mill structure reason is restricted.In addition, use the bolt after rolling, need carry out fixed-length cut-off according to the length of using, the stub bar that all can leave not enough length after blocking causes the waste of material, manpower and resource as waste disposal.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of with wire rod as rolling material, the rolling length of bolt is unrestricted; Waste material appears after also avoiding blocking bolt; The roller machine head of the simple a kind of bolt cold-rolling mill of rolling mill practice.
The technical scheme that solves the problems of the technologies described above is: a kind of roller machine head of bolt cold-rolling mill; Said roller machine head comprises: a pair of roller for screw thread, the driver element that are used for rolling bolt; It is identical that said a pair of roller for screw thread is hinged on structure respectively; On a pair roller frame of position symmetry, said a pair roller frame all is fixed in the rotating head intracoelomic cavity; Said rotating head body connects driver element, and on the frame that is supported on bolt cold-rolling mill of rotating; The center correspondence of said rotating head body both sides is provided with the cable-through hole that reinforcing bar runs through, and said rotating head body is centered close to the mid point of a pair of roller for screw thread centre-to-centre spacing; The axial line of said a pair of roller for screw thread all tilts with rotating head body center line, and the angle of said inclination is the bolt lift angle α that is rolled.
The invention has the beneficial effects as follows: the present invention is applicable to that the wire rod reinforcing bar is as rolling blank; Reinforcing bar is under the tow conveyor structure cooperates; Reinforcing bar is got in the roller machine head by the center of certain speed along roller machine head, and the reinforcing bar outer surface is rolled out screw thread under reinforcing bar and the roller for screw thread relative motion.A because reinforcing bar blank moving linearly; And do not rotate, so after the blank of endless is sent into roller for screw thread endlessly, just can roll out the bolt of endless; Carry out fixed-length cut-off according to the bolt length requirement; Solve bolt and be restricted, realize no stub bar on line production, reach labor savings while production process and do not produce the purpose of stub bar loss in production process length.Practice thrift the labour cost and the material cost of each operation of the cold rolling front and back of bolt.Noise of the present invention is low, and automaticity is high, is suitable for the bolt production of different size.
