Description
Technical field
The field that the screw thread rib shape that the utility model relates to reinforcing bar finished product groove is produced, particularly relates to a kind of asymmetric rib shape of screw-thread steel finished product groove.
Background technology
Require in the screw-thread steel standard GB/T 1499.2-2007 now performed: the angle a of reinforcing bar cross rib side and rebar surface must not be less than 45 °.Rolling production enterprise is for guaranteeing that cross rib side angle meets standard, and traditional control method uses both sides side angle to the rib shape groove being called 50 °.
In actual production, finished product groove (particularly large gauge) affects because reinforcing bar takes off groove.The side side angle rapid wear first going out de-groove can be caused, cause the side angle of cross rib both sides inconsistent and the side of serious wear is very easily less than 45 °; For this reason, manufacturing enterprise has to strictly to control finished product groove online service time.Therefore groove can be caused too short for online service time, and roll utilization rate is not enough, have impact on economic benefit.
Utility model content
For above-mentioned Problems existing, the utility model object is to provide a kind of and improves finished product groove rib shape, improves the wear resistance of groove side angle that side easy to wear, extends the asymmetric rib shape of the screw-thread steel finished product groove of groove online service time.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of asymmetric rib shape of screw-thread steel finished product groove, described asymmetric rib shape is arranged on the upper of milling train, under roll on Kun, described asymmetric rib shape is trapezoidal rib groove, described rib groove comprises large mouth groove and osculum groove, the reinforcing bar cross rib side of described osculum groove and the angle of roller surface are 55 °, the reinforcing bar cross rib side of described osculum groove and the angle of rib groove center line are 35 °, reinforcing bar cross rib side and the roller surface angle of described large mouth groove are 50 °, the reinforcing bar cross rib side of described large mouth groove and the angle of rib groove center line are 40 °.
The side angle angle of the cross rib of side easy to wear in rib groove, when the rib groove of processed finished products roll, is strengthened separately 10 ° by the utility model, forms the asymmetrical shape that both sides angle is inconsistent; And in use, all the time angle larger side is used for the outlet side of finished product groove; This side side angle guaranteeing rib shape in use, even if there are wearing and tearing, also there will not be side angle lower than the phenomenon of opposite side.
Improve as one of the present utility model, the topping roll of described milling train is in rotating counterclockwise, and described osculum groove is arranged on the side on the clockwise direction of large mouth groove.
Improve as one of the present utility model, the bottom roll of described milling train is in rotating clockwise, and described osculum groove is arranged on the side in large mouth groove counter clockwise direction.
The production method of the asymmetric rib shape of screw-thread steel finished product groove described in the utility model, its detailed production method is as follows:
1) roll surface circumferentially of screw-thread steel finished product groove pass tank car to the outside of the rib groove on upper and lower roll is adopted to carry out preprocessing;
2) reconditioning is carried out to common rib shape process tool, select wherein side, the angle of inclination of its side is worn into 35 °, form asymmetric ridge knife tool;
3) optional step 2) in the rib groove of asymmetric ridge knife tool to upper and lower roll that obtain carry out Milling Machining respectively;
4) Roller Machining good after, demarcate top and bottom rolls, and assemble roll respectively by diverse location, the osculum groove of installation process middle rib groove is arranged on the outlet side of milling train;
5) after installation, by the rotation Rolling Production spiral of upper and lower roll.
In the operating process of step 3) described in the utility model, need topping roll and the bottom roll of demarcating roll, both are processed respectively.
In the operating process of step 3) described in the utility model, the large mouth groove on topping roll and bottom roll in rib groove is contrary with the Working position of osculum groove.
The outlet side of milling train described in the utility model is the exit side of the final products of milling train.
In the process of preprocessing described in the utility model, need to polish to the surface of upper and lower roll, polish operation on the contact position of roll surface and rib groove simultaneously.
The utility model has the advantage of: the both sides side angle angle of the reinforcing bar cross rib of production of the present utility model is all greater than 45 °, ensure that the both sides side angle of reinforcing bar all meets standard-required, and the both sides side angle degree of wear is basically identical.Simultaneously rib groove more traditional rib shape online service time to extend 1.5 ~ 2.5 times, reduce roll cost expiration obvious; After using the groove of the asymmetric processing of cross rib side angle, that side wear time that angle increases is elongated.
