During modern steel is produced, pair of parallel commonly used is arranged, the roll shaft of reverse rotation comes rolled plate, roll shaft to the material high-pressure, utilizes the shearing force between two roll shafts under the effect of hydraulic system pressure, can will continue to offset by the steel ingot of pressure area between two roll shafts.But in process, the tiny chip of steel ingot is adhered in the meeting that cannot avoid on the roll shaft, these chips can stay cut and hole hole, i.e. roll marks on the surface of rolled parts in the operation of rolling, thereby the surface accuracy of influence of rolled spare, even can cause scrapping of rolled parts.
The method of removing roll shaft surface blot mainly in two steps at present; at first be to remove manually; the crew uses manual wiping roller device (combination of wooden stick and wiping head) wiping is carried out on the roll shaft surface that produces roll marks; because the roll shaft outer surface is a periphery; the cleaning angle is big, cleaning effect is often undesirable, efficient is not high yet; the more important thing is, in this course because working roll is non-stop-machine, so whole artificial wiping roller process exists very large potential safety hazard.In addition; because artificial wiping roller cleaning effect is bad; how long have more than is needed roll shaft often make; normally several hours; when the rolled parts surface accuracy that processes when the roll shaft of artificial cleaning does not reach and requires; will carry out for second step: shut down and change working roll, whole roll change work need be shut down more than 30 minutes, so will influence the output of whole unit.Because the roll shaft of changing must could continue by the processing of follow-up lathe to use, production cost of products is further risen again.
Summary of the invention
Technical problem to be solved in the utility model mainly is to provide a kind of device that can clean the roll shaft surface in the roll shaft process timely and effectively.
The utility model is achieved through the following technical solutions:
A kind of roll marks spot wiper that is used for rolling mill, it is characterized in that: described wiper comprises by motor-driven sliding spiral pair, sliding spiral pair comprises the screw mandrel that be arranged in parallel with the roll shaft active section, screw mandrel is provided with the thread segment relative with the roll shaft active section, and the length of wire rod thread section is more than or equal to the length of roll shaft active section, the wire rod thread section is provided with the nut that matches with it, nut is fixed with cylinder towards a side of roll shaft active section, piston in the cylinder is provided with piston rod and stretches out outside the cylinder, the end that piston rod stretches out is provided with the wiping head, and the wiping head on the operating position contacts with the outer surface of roll shaft active section.
In when work, the rodless cavity of cylinder constantly has pressed gas to inject, and piston rod is stretched out, the wiping head on the piston rod just with rotate in the working roll outer circumference surface contact, and keep this invariant position; This moment starter motor, the motor-driven screw mandrel, screw mandrel is rotated, nut on the wire rod thread section at the drive lower edge of screw mandrel screw axis to moving linearly, thereby drive moving horizontally of wiping head on the cylinder realization piston rod fixedly connected with nut, and then reach the purpose of wiping the roll shaft outer circumference surface clearly.Because screw mandrel and roll shaft be arranged in parallel, so the wiping head can contact with the roll shaft outer circumference surface in the process that moves horizontally always; Because the length of thread segment is corresponding more than or equal to axial length and both positions of spiral shell axle active section on the screw mandrel, thus when the wiping head when wire rod thread Duan Yiduan moves to the other end, can clean the outer circumference surface of whole roll shaft active section comprehensively; Simultaneously,, can control the dynamics of a wiping wiping, also can regulate the wiping head, avoid excessive velocities wiping head to impinge upon on the roll shaft to the speed that roll shaft moves by regulating pressure by the pressed gas of piston below.
Further, in actual use, consider that roll shaft is longer, its active section length is usually more than 1M, the screw mandrel length that adapts with it is also more than 1M, the wiping head can be subjected to the radial reaction force of roll shaft in the process of wiping roll shaft, this power passes to screw mandrel by the nut that moves horizontally on the screw mandrel, elongated screw mandrel is easy to generate flexural deformation under the effect of long-time radial load, therefore can increase a support bar is used for holding nut, thereby increase the rigidity of screw mandrel, avoid the screw mandrel distortion.Support bar and roll shaft lay respectively at the screw mandrel both sides, three's axis is in same plane and parallel to each other, the support bar active section is corresponding with the wire rod thread section, and the length of strut active section is more than or equal to the length of wire rod thread section, support bar can contact with the outer surface of nut or slightly gapped being advisable with the support bar outer surface with distance between the screw mandrel, and the gap is generally in the scope of 0.5mm～0.7mm.
