Abstract

The invention relates to a device used to produce circular cold rolling twisting reinforcing steel bar. It includes feeding reel, mechanism reciprocating type guide wheel device, circular cold rolling twisting reinforcing steel bar cold rolling forming device, drawing machine, wire-rewinding machine, die orifice formed by cold rolling forming device and alloy roller. The invention can produce circular reinforcing steel bar, rewind catch basin bar, has high production efficiency.

Description

A kind of equipment of producing circular cold-rolled torsion steel bar

Affiliated technical field: the invention belongs to the metal material cold processing technique, especially circular cold-rolled torsion steel bar processing technique field.

Background technology: present cold-rolled torsion steel bar production technology is by obtaining cold-rolled torsion steel bar for cold twisting moulding behind the flat with hot rolling dish round bar is cold rolling, processing step is:--cold rolling--cold twisting becomes the vertical bar cold-rolled torsion steel bar to hot rolling dish garden reinforcing bar through straightening, and there is following major defect in this technology:

1, can only produce the flat cold-rolled torsion steel bar;

2, because of the restriction of flat type cold-rolled torsion steel bar shape, the cold-rolled torsion steel bar of producing can not the harvest wire rod, can only the supply of material of vertical bar scale, increased the loss that the user uses the steel blanking in actual applications;

3, be subjected to products characteristics and process limitation, speed of production is 40 meters/minute only, and production efficiency is lower.

Summary of the invention purpose of the present invention provides a kind of circular cold-rolled torsion steel bar of producing for the above-mentioned defective that overcomes existing cold-rolled torsion steel bar production technology and equipment existence thereof just, and the circular cold-rolled torsion steel bar of producing is the harvest wire rod easily, a kind of equipment of producing circular cold-rolled torsion steel bar that production efficiency is higher.

The present invention is achieved by the following technical solution.

Behind the pay off rack of wire rod round metal wire rod to be processed, be disposed with: mechanical reciprocating type guide wheel device, circular cold-rolled torsion steel bar cold rolling moulding device, wire drawing machine, admission machine; The die orifice of circular cold-rolled torsion steel bar cold rolling moulding device is one group and props up the vertical layout of alloy roll annular by 4-7, and is the structure that 16 degree, one 20 degree oblique angle a are provided with round metal wire axis line, and the round metal wire rod forms circular cold-rolled torsion steel bar from die orifice by the back.

Because the present invention removes the round metal wire rod except that the metal wire rod oxide layer by the reciprocating type guide wheel device of machinery under the traction of wire drawing machine; And the round metal wire rod is entered circular cold-rolled torsion steel bar cold rolling moulding device carry out roll forming under the traction of wire drawing machine, and because circular cold-rolled torsion steel bar profile is a sub-circular, can carry out the high speed take-up by take-up stand, realize with the disposable production cold-rolled torsion steel bar of wire rod mode of supplly; Thereby improved production efficiency, the speed of production of the circular cold-rolled torsion steel bar of the present invention is 〉=180 meters/minute, and is matchless by producing the flat cold-rolled torsion steel bar.Be provided with to produce by the disposable cold rolling explained hereafter of the present invention equipment and meet the circular cold-rolled torsion steel bar that GB requires.

Further set forth content of the present invention below in conjunction with Figure of description and embodiment.

Description of drawings Fig. 1 is a layout drawing of the present invention;

Fig. 2 is circular cold-rolled torsion steel bar cold rolling moulding device die orifice structure chart.

The specific embodiment such as Fig. 1, the present invention is disposed with behind the pay off rack 1 of wire rod round metal wire rod 6 to be processed: mechanical reciprocating type guide wheel device 2, circular cold-rolled torsion steel bar cold rolling moulding device 3, wire drawing machine 4, admission machine 5; The die orifice 8 of circular cold-rolled torsion steel bar cold rolling moulding device 3 is one group and props up alloy roll 7 annular vertical layouts by 4-7, and being the structure that 16 degree, one 20 degree oblique angle a are provided with round metal wire rod 6 axial lines, round metal wire rod 6 forms circular cold-rolled torsion steel bar from die orifice 8 by the back.

The concrete production process of the present invention grinds pointed drawing head for the head with the round metal wire rod 6 on the pay off rack 1: the oxide layer of then the round metal wire rod being removed the round metal wire surface under the traction of wire drawing machine by the reciprocating type guide wheel device 2 of machinery by directive wheel to its tensioning and the pressure that stretches tight; The directive wheel setting of the reciprocating type guide wheel device 2 of machinery can be multiple mode, also repeat, thereby purpose is the round metal wire rod to be wrapped in be bent on the directive wheel and hold out against to be subjected to tensioning and the pressure that stretches tight, and makes the spalling of oxide layer of round metal wire surface; Circular cold-rolled torsion steel bar cold rolling moulding device 3 is an existing equipment, for the round metal wire rod is rolled into bull and round, online material forming die orifice is provided with one group and props up alloy roll 7 annular vertical layouts by 4-7, and be the structure that 16 degree, one 20 degree oblique angle a are provided with round metal wire rod 6 axial lines, the anglec of rotation of the angle decision torsion steel bar at a oblique angle, round metal wire rod 6 forms circular cold-rolled torsion steel bar from die orifice 8 by the back, as Fig. 2.After being pulled, laterally passes through in round metal wire rod 6 by for example 6 moulding die orifices that annular alloy roll 7 is formed, round metal wire rod head is become 6 statures by 6 annular alloy roll pressed, roll rotator seat on the meanwhile circular cold-rolled torsion steel bar cold rolling moulding device 3 drives axially rotation of round metal wire rod 6, rotary speed determines the girth that reverses of reinforcing bar, the reinforcing bar that rolling is gone out is 6 twisted bar, as adopt 4 annular alloy rolls, then circular cold-rolled torsion steel bar just has 4, adopt 6 annular alloy rolls, then circular cold-rolled torsion steel bar just has 6.And then the circular cold-rolled torsion steel bar that will be shaped by guider by spool take-up harvest wire rod finished product.The cold-rolled torsion steel bar of one-tenth dish can be pressed user's request straightening blanking by the outer aligning cutting-off device of this technology.
