The utility model discloses a cantilever coiling drum end part supporting device for a coiling machine. The cantilever coiling drum end part supporting device comprises a shaft b which is used for the expansion and contraction of a coiling drum; a supporting sleeve is arranged on the external surface of the shaft b; a slide bushing a and a slide bushing b are arranged between the shaft b and the supporting sleeve; the shaft b is in indirect contact with the supporting sleeve through the slide bushing a and the slide bushing b; a sleeve cup b is supported outside the supporting sleeve through a bearing b; the two ends of the sleeve cup b are respectively connected with an end cover and a gland b; and the supporting sleeve is fixed at the end part of the shaft b through a press plate and a spacer sleeve. According to the cantilever coiling drum end part supporting device for the coiling machine, the cantilever coiling drum end part supporting device is not in relative axial movement relative to a coiling machine body, so that the relative immobilization of positions of a movable support and an end part support is guaranteed, and a coiling drum end part bearing can be enabled to be in stress uniformity under different working conditions, thereby avoiding the damage to the coiling drum end part bearing; and the reduction of the production efficiency caused by the fact that the production can not be carried out smoothly arising from accidents caused by the damage of the bearing is avoided.
Description
Technical field
The utility model belongs to steel rolling engineering equipment technical field, is specifically related to coiling machine cantilever reel ends bracing or strutting arrangement.
Background technology
Coiling machine is the important auxiliary equipment of mill, and their duty directly affects the performance of mill production.And reel is the core component in the coiling machine, will bear 20～35 tons roll coil of strip weight at work, will resist 10～20 tons band tensile stress distortion simultaneously.In order to improve the reel stress, to reduce the reel deflection deformation, be provided with movable supporting at the reel cantilever end reel ends is supported.Existing reel ends bracing or strutting arrangement, will break down and accident moving the easy reel ends bearing that damages under the situation not in place for moving axially structure like this.
Summary of the invention
The purpose of the utility model provides a kind of coiling machine cantilever reel ends bracing or strutting arrangement, solves the problem that the end portion, supports damage of bearings in use appears in existing reel easily, avoids equipment fault to cause the accident, and guarantees the smooth production of unit.
The technical scheme that the utility model adopts is; Coiling machine cantilever reel ends bracing or strutting arrangement; Comprise the axle b that reel harmomegathus is used, axle b outer surface is provided with support set, is provided with sliding sleeve a and sliding sleeve b between axle b and the support set; Axle b is through sliding sleeve a, sliding sleeve b and support set mediate contact, and support set is outer to be supported with a set of cups b through bearing b; The two ends of a set of cups b connect end cap, gland b respectively, and support set is fixed on the end of a b through pressing plate and spacer sleeve.
The utility model beneficial effect is: the reel ends bracing or strutting arrangement relatively and the coiling machine body do not move to axial; Guarantee the position relative fixed of movable supporting and end portion, supports, can be under different operating modes so that the reel ends shaft strength is evenly avoided its damage; Avoided because of accident appears in damage of bearings, made production not carry out smoothly and reduce production efficiency.

Fig. 1 is the structural representation of existing coiling machine end portion, supports device.
Fig. 2 is the local enlarged diagram of Fig. 1.
Fig. 3 is the structural representation of the utility model coiling machine cantilever reel ends bracing or strutting arrangement.
Among the figure: 1, fanning strip, 2, axle a, 3, ring, 4, a set of cups a, 5, bearing a, 6, gland a; 7, lining, 8, swing arm, 9, gland b, 10, a set of cups b, 11, sliding sleeve a, 12, end cap; 13, sliding sleeve b, 14, support set, 15, axle b, 16, spacer sleeve, 17, pressing plate, 18, bearing b.
The specific embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to the utility model.
The structure of existing coiling machine end portion, supports device is as shown in Figure 1.Spool axis shown in the figure and swing arm 8 axis must guarantee 90 degree angles, and reel ends part a set of cups a4 male cone (strobilus masculinus) could contact with movable supporting part lining 7 inner conical surfaces fully, and bearing a5 could be evenly stressed.In order to make both vertical each other, the invariant position between parts mandrel that must guarantee to be combined into and the fanning strip 1 after the relative motion by axle a2, ring 3, a set of cups a 4, bearing a5, gland a6, promptly size A must guarantee design load among Fig. 1.Fanning strip 1 is in the axis direction relative fixed; So the position of the assembly mandrel of axle a2, ring 3, a set of cups a 4, bearing a5, gland a6 just requires to fix; But need on reel, be set with sleeve because of production in the actual production process; The assembly mandrel of a feasible axle a2, ring 3, a set of cups a 4, bearing a5, gland a6 can't move and put in place, shown in accompanying drawing 2.Size B value shown in Figure 2 is greater than Design Theory required value A; Movable supporting is in swing process; When the swing arm 8 axis angle K of spool axis and movable supporting spent less than 90, lining 7 inner conical surfaces just contacted with 2 of Q with the P of reel ends part a set of cups a4, and the result causes bearing a5 discontinuity.Damage the bearing of cantilever reel ends unbalance stress in the situation of high-speed overload, thereby cause accidents such as broken belt, damage roll, not only bring huge direct economic loss to influence normal production again.
The structure of the utility model coiling machine cantilever reel ends bracing or strutting arrangement is as shown in Figure 3, mainly comprises: securing member is used in gland b9, a set of cups b10, sliding sleeve a11, end cap 12, sliding sleeve b13, support set 14, axle b15, spacer sleeve 16, pressing plate 17, bearing b18 and installation.Specifically, comprise reel harmomegathus with axle b15, axle b15 is through sliding sleeve a11 and sliding sleeve b13 and support set 14 mediate contacts, and sliding sleeve a11 and sliding sleeve b13 are embedded in the support set 14; Support set 14 is outside equipped with bearing b18, and is supported with a set of cups b10 through bearing b18; A set of cups b10 two ends are connected with end cap 12, gland b9 respectively, and a set of cups b10, end cap 12 are used to compress bearing b18 with gland b9; Support set 14 is fixed on the end of a b15 through pressing plate 17 and spacer sleeve 16.
The coiling machine cantilever reel ends bracing or strutting arrangement of the utility model; When work by gland b9, a set of cups b10, sliding sleeve a11, end cap 12, sliding sleeve b13, support set 14, bearing b18 and the relative and coiling machine body of the global facility of forming with securing member is installed is fixed at axial location; In reel harmomegathus process, have only a b15 that axially-movable is arranged, axle b15 is in sliding sleeve a11 and sliding sleeve b13 slides within.The harmomegathus what state of reel no matter, reel ends supports and all can well contact with the movable supporting device, guarantees that bearing b18 is stressed evenly to avoid it to damage, and guarantees normally carrying out smoothly of production.
The utility model coiling machine end portion, supports device be aim at bear higher roll coil of strip weight, than hightension and the coiling machine cantilever spool designs that runs up.This apparatus structure is novel, easy to adjust, installation is simple and easy; No matter how reel harmomegathus size can both guarantee that reel ends well contacts with movable supporting two conical surfaces, guarantees that the reel ends bearing is evenly stressed, has avoided causing the accident because of unbalance stress damages bearing, has satisfied the needs of on-the-spot different operating modes.
