Abstract
The utility model relates to a hot rolling screw steel rod straightening and cutting machine, in particular to a straightening mechanism for hot rolling screw steel rod straightening and cutting machine. The utility model is characterized in that five straightening blocks(6) are arranged inside a rotary cylinder(1) of a straightening mechanism. Inside a guide groove, distance between the straightening block(6) and an axial line of the rotary cylinder(1) is adjusted by an adjusting screw(2). A bearing(4)arranged at two ends of a wheel frame(5) is arranged on the straightening block(6), while a straightening roller(7) is arranged on the wheel frame(5). As the utility model adopts the designing, no scratch marks are existed on a vertical rib and horizontal rib of the hot rolling screw steel rod after the straightening, and mechanical properties of the steel rod is same as that before the straightening. .
Description
The utility model relates to a kind of hot-rolled screw thread reinforcing bar aligning cutting-off device, particularly relates to a kind of straightening mechanism of hot-rolled screw thread reinforcing bar aligning cutting-off device.
Be used for straightening hot-rolled screw thread reinforcing bar at present, most of employing levels---vertical multiple roll straightening scheme and drum-type curve roller straightening scheme, because being used for the straightener roll of straightening does circumferential rolling friction on the surface of reinforcing bar, thereby make steel longitudinal rib, cross rib surface after the straightening be subjected to the different damage of degree, by the flow harden phenomenon, change the mechanical property of reinforcing bar, can not satisfy instructions for use.
The purpose of this utility model is to provide a kind of straightening mechanism of hot-rolled screw thread reinforcing bar, and reinforcing bar is after this mechanism's straightening, and its vertical rib, cross rib surface do not have cut, and the mechanical property of reinforcing bar does not have change with the last sample of straightening, has satisfied the instructions for use of hot-rolled screw thread reinforcing bar.
The straightening mechanism of this hot-rolled screw thread reinforcing bar aligning cutting-off device is made up of rotating cylinder 1, adjustment screw 2, pressing plate 3, rolling bearing 4, wheel carrier 5, straightening piece 6, straightener roll 7, rolling bearing 8 and bearing cap 9 etc., it is characterized in that: straightening piece 6 is installed in the guide-track groove of rotating cylinder 1, can move up and down the distance of straightening piece 6 and rotating cylinder 1 axis by adjustment screw 2, wheel carrier 5 two ends are equipped with rolling bearing 4 and are installed in the straightening piece 6, and straightener roll 7 is installed on the wheel carrier 5; Straightening piece 6 rotates with rotating cylinder 1, can relatively rotate between wheel carrier 5 and the straightening piece 6; Straightener roll 7 is installed in the wheel carrier 5 by rolling bearing 8, and is rotatable at the axial direction straightener roll 7 of rotating cylinder 1, and do not rotate in circumferential direction, in 5 one-tenth inactive states of wheel carrier; Straightener roll 7 has identical grooved, wherein: b=a+0.1mm, R=1/2d, h=0,47-0.55R; Centre distance straightener roll (7) external diameter of grooved R size is h, and both sides R face contacts with the reinforcing bar inner diameter d, does not contact with cross rib, and the vertical rib two sides of reinforcing bar are in grooved b.
Drawings and Examples
Accompanying drawing 1 is the structural representation of utility model straightening mechanism
Accompanying drawing 2 is the A-A line cutaway views among Fig. 1
Accompanying drawing 3 is grooved enlarged drawings of straightener roll 5
Accompanying drawing 1 is the disclosed embodiment of the utility model (seeing Fig. 1, Fig. 2, Fig. 3), 5 the straightening pieces 6 of in rotating cylinder 1 guide-track groove, packing into, pressing plate 3 is fixing with rotating cylinder 1, pressing plate 3 is provided with screwed hole, but adjustment screw 2 is by the distance of screwed hole up-down adjustment straightening piece 6 with rotating cylinder 1 axis, it is combined with straightening piece 6 that bearing 4 is equipped with at wheel carrier 5 two ends, and it is fixing with wheel carrier 5 usefulness bearing caps 9 that bearing 8 is equipped with at the straightener roll two ends.
Need to be penetrated respectively in the grooved of forming by 5 pairs of straightener rolls 6 by vertical rib direction by the hot-rolled screw thread reinforcing bar of straightening, head, tail, middle straightening piece 6 are regulated centering with adjustment screw 2 respectively, all the other straightening piece 6 directions can equidirectional or rightabout and rotating cylinder 1 journal offset certain distance, regulate with adjustment screw 2, each pushes down the reinforcing bar inner diameter d with suitable drafts, and reinforcing bar is advanced by the carry-over pinch rolls traction of aligning cutting-off device.Rotating cylinder 1 is high speed rotary under the effect of motor power, and the reinforcing bar original curved has been done the repeatedly rightabout bending in a plurality of straightening unit, makes reinforcing bar obtain straightening.
In rotating cylinder 1 high speed rotary process, 1 one-tenth inactive state of straightening piece 6 relative rotating cylinders, along with rotating cylinder 1 revolution, because the effect of rolling bearing 4,6 existence of 5 pairs of straightening pieces of wheel carrier relatively rotate, with rotating cylinder 1 rotation.Straightener roll 7 is contained in the wheel carrier 5, because the effect of rolling bearing 8, at the axis direction of rotating cylinder 1, straightener roll 7 exists with wheel carrier 5 and relatively rotates, and is that the cross rib direction becomes relative static conditions with the circumferential direction of reinforcing bar, does not rotate.Straightener roll 7 is at the axial direction of reinforcing bar, because grooved R center roll surface h distance, the R two sides only contact a part with the reinforcing bar inner diameter d, do not contact with cross rib, vertical rib two sides are stuck among the grooved b, R, h, b, a size are determined by the size shown in the bar gauge, thereby straightener roll 7 is only done rolling friction with the reinforcing bar inner diameter d in circumferential direction, do not contact with steel longitudinal rib, cross rib, thereby guaranteed its vertical rib cross rib no marking of hot-rolled screw thread reinforcing bar after this straightening mechanism straightening effectively, the mechanical property of reinforcing bar does not have change.
