Abstract
The utility model relates to a leveller for levelling and processing metal plates, comprising a stand, an upper levelling roller mechanism, a lower levelling roller mechanism and levelling roller lifting motors. The upper levelling roller mechanism is fixedly connected with the stand, and the lower levelling roller mechanism is connected with the stand through an adjusting device which can adjust the parallelism and the space between the lower levelling roller mechanism and the upper levelling roller mechanism; and the levelling roller lifting motors are connected with the adjusting device. The leveller can accurately control the amount of feed and keep the stability of a lower levelling roller group and then achieve accurate levelling and processing.
Description
Technical field
The utility model relates to the levelling machine of metal blank leveling processing, relates in particular to a kind of roller levelling machine.
Background technology
There is the flatness requirement in domestic consumer for employed sheet metal.No matter be flat cold-rolled sheet or SPHC, before dispatching from the factory, the smoothing operation must be arranged.Wherein SPHC generally is to appear on the scene with the roll bending form, and the flatness index need be carried out the requirement that high-precision smoothing processing just can meet the user end of than.
Present levelling machine is widely applied, its primary structure is that upper and lower straightener roll mechanism is set on frame, following straightener roll mechanism is fixedly connected on the frame, have only roller rotatable, last straightener roll flexibly connects frame, go up the straightener roll trace and move by an adjusting device, transmission mechanism driving, spacing, the depth of parallelism in the adjustment between straightener roll and the following straightener roll, and then realization is to the adjustment of plate plane degree.Since the prolonged application, find that above structure exists significantly and by the problem of people's long-standing neglect, that is exactly to connect adjusting device, the transmission mechanism of going up the straightener roll group to have the gap, deadweight factor in conjunction with last straightener roll group, adjusting device, when the upper and lower continually trace of last straightener roll group is mobile, can cause the volume under pressure inaccuracy.The volume under pressure misalignment that is caused by this play can cause the mass defect of serious generality.
The utility model content
The utility model is at above problem, provides under a kind of situation that can't eliminate play in the mechanical transmission component, eliminates the influence of play to the parts action amount of feeding, thereby improves the levelling machine of machining accuracy.
The technical solution of the utility model is: comprise frame, last straightener roll mechanism, following straightener roll mechanism, straightener roll lifting motor, last straightener roll mechanism is fixedly connected on the frame, following straightener roll mechanism can make it be connected with the adjusting device that the depth of parallelism is adjusted with the inter-agency spacing of last straightener roll with frame by one, and the straightener roll lifting motor links to each other with described adjusting device.
Described adjusting device comprises power transmission shaft, elevating lever, bulb, ball bowl, plane bearing, the sill that is arranged on the frame; Power transmission shaft is horizontally set on frame lower, links to each other with the straightener roll lifting motor; Elevating lever is vertically connected on the frame, and power transmission shaft is realized lifting by the drive mechanism elevating lever in vertical direction; The top of elevating lever is provided with bulb, flexibly connects a ball bowl on the bulb, and the upper surface of ball bowl is provided with the plane bearing joint face, and the corresponding ball bowl of sill position is provided with continuing surface, and the ball bowl links to each other by plane bearing with sill.
It also comprises the guide rail plate, and the upper surface of guide rail plate connects the continuing surface of sill, and lower surface connects the plane bearing on the ball bowl.
The utility model has changed the traditional mode of straightener roll group upper dynamic in the past, adopt straightener roll group feeding down to adjust, the reason of bonded block deadweight, feasible play as screw thread transmission class mechanical transmission mechanism can not exert an influence to the amount of feeding, thereby can accurately control the amount of feeding.The lowering or hoisting gear of considering down school roller group four bights when carrying out depth of parallelism adjustment can occur interfering mutually, the utility model has adopted bulb ball bowl plane bearing bindiny mechanism, reduced restriction to four bight frees degree, the certain vertical lift amount in one of them bight can be decomposed into the microdisplacement of vertical direction displacement and horizontal direction by the bulb mechanism of this point, and the bulb ball bowl plane bearing bindiny mechanism in other bight passes through planar slip, bulb deflection is decomposed the microdisplacement of above-mentioned horizontal direction, thereby keep the stability of straightener roll group down, and then realize accurately smoothing processing.
