Abstract

The utility model discloses a pressure roller device capable of continuously adjusting the levelness. The pressure roller device comprises a pressure roller, bearings, eccentric bushings, bearing pedestals, an oscillating arm support and fastening pieces, wherein the eccentric bushings are hollow convex structures; shaft shoulder parts at the two ends of the pressure roller are respectively matched with inner rings of the eccentric bushings at the two ends through the bearings; outer rings of lug bosses of the eccentric bushings at the two ends are respectively matched with the bearing pedestals which are fixed at the two ends of the oscillating arm support, and the eccentric bushings are fixed on the bearing bushings through the fastening pieces. The pressure roller device can effectively solve the problem that the levelness or parallelisms among the surface of the pressure roller, the surface of a material coil and the external surface of a winding shaft of a decoiler or a coiling machine are consistent.

Description

A kind of hold-down roller device that can adjust levelness continuously

Technical field

The utility model belongs to the metallurgical machinery equipment technical field, relates in particular to a kind of hold-down roller device that can adjust levelness continuously.

Background technology

Sheet metal strip generally all existed with the material roll form with rolling end of a period before rolling, got so milling train configuration uncoiler or coiling machine are realized the uncoiling of band.Corresponding is that material twists in uncoiling process, the coiling process after the strip-rolling before rolling, wears all or part of stage of the band and the normal operation of rolling; All need rely on the hold-down roller device will treat that the band part of uncoiling and band to be batched partly are pressed on uncoiler, coiling machine or the corresponding material volume; And along with uncoiling, batch, the auxiliary feeding of rolling process, rewinding, the ironing band.The effect of hold-down roller device be farthest guaranteed material twist in uncoiling, batch, when rolling band can sideslip and the material volume bad phenomenon such as loose winding, turriform, staggered floor can not take place.Simultaneously, the hold-down roller device also plays the effect to band, the ironing of material volume.

At present; The employed hold-down roller device of sheet metal strip rolling equipment is in practical work process; Band often occurs and press uneven, as not press tightly and be attended by vibrations situation; And then phenomenons such as loose winding, turriform, staggered floor, band sideslip, operation of rolling instability appear, cause that production efficiency is low, product quality is defective.

The appearance of above phenomenon and situation generally stems from following reason:

1, the swing arm support at hold-down roller place is generally monosymmetric large welded structures, the difficult control of form and position tolerances such as the symmetry at weldment two ends, the depth of parallelism, and the relative machined piece of precision is lower;

2, often produce some thick bands, hard band (like high-strength steel band, hard aluminium alloy band, high-strength copper alloy band etc.), defective band (as thick difference is big, heat treatment is inhomogeneous, quality of edges difference etc.), and mill speed is too high, speed is unstable, the swing arm stiffness of support not to the utmost ideal etc. all can cause the appearance of above situation.

Existing hold-down roller device is owing to the method that can't reach through the levelness of continuous adjustment pressure roller with the applying degree of expecting volume solves the problems referred to above; And can only rely on the machining accuracy of strict control swing arm support, carry out scrap build after going wrong and reduce band and press degree uneven and that problem such as do not press tightly, and do not have other comparatively appropriate, effective measures.

Summary of the invention

For addressing the above problem; The purpose of the utility model provides a kind of hold-down roller device that can adjust levelness continuously; Reasonable in design, simple in structure; Cost is lower, can effectively solve because roller surface is rolled up the surface with material, opened coiling machine spool outer surface levelness or the inconsistent problem of the depth of parallelism.

In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:

A kind of hold-down roller device that can adjust levelness continuously; Comprise pressure roller, bearing, eccentric bushing, bearing block, swing arm support and securing member; Said eccentric bushing is the convex structure of hollow; The shaft shoulder at pressure roller two ends part matches through the inner ring of bearing with the eccentric bushing at two ends respectively, the boss outer ring of the eccentric bushing at two ends respectively be fixed on the swing arm support on the bearing block at two ends match, eccentric bushing is fixed on the bearing block through securing member.

The described hold-down roller device that can adjust levelness continuously offers the ring-type slotted hole on the step surface of its eccentric bushing.

Owing to adopt technique scheme, the utlity model has following superiority:

Simple in structure, cost is lower, regulate with easy to maintenance, and when pressure roller occurs not pressing tightly, press phenomenon such as uneven with material volume or band, the relative angle of the eccentric bushing through adjustment pressure roller two ends, and then pressure roller is reached and expect to roll up purpose parallel, that compress.

Among the figure: the 1-pressure roller; The 2-bearing; The 3-eccentric bushing; The 4-bearing block; 5-swing arm support; The 6-securing member.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

In conjunction with Fig. 1, Fig. 2, a kind of hold-down roller device that can adjust levelness continuously comprises pressure roller (1); Bearing (2); Eccentric bushing (3), bearing block (4), swing arm support (5) and securing member (6); Said eccentric bushing (3) is the convex structure of hollow; The shaft shoulder part at pressure roller (1) two ends matches through the inner ring of bearing (2) with the eccentric bushing (3) at two ends respectively, matches with the bearing block (4) that is fixed on the last two ends of swing arm support (5) respectively in the boss outer ring of the eccentric bushing at two ends (3), and described eccentric bushing (3) is fixed on the bearing block (4) through securing member (6).Offer the ring-type slotted hole on the step surface of said eccentric bushing (3).

In the course of the work; When there is certain angle in pressure roller (1) with horizontal plane or with the material volume; When being fitting tightly fully that pressure roller (1) can't be parallel with the material volume; With eccentric bushing (3) the symmetry rotation at pressure roller (1) two ends, and then adjust the levelness of pressure roller (1) or the parallel applying degree of rolling up with material.
