Description

Wrap-up

Technical field

Metal working technical area is the utility model is related to, it is more particularly to a kind of to improve the wrap-up for unreeling precision.

Background technology

Wrap-up can be all generally used in the processing of sheet metal strip, needs to utilize winding when band needs to be processed Device is unreeled.Wrap-up is a kind of roller shape structure, and before blowing prepares, wrap-up passes through the centre of winding, using " swollen It is swollen " mode by winding jam-packed, so when wrap-up rotates, winding can just follow it rotate together, then make band Material slowly loosens.The roll surface of wrap-up is typically assembled by many arcuate members.The General Principle of wrap-up " expansion " To allow all arcuate members to jack up outward by hydraulic pressure, then packed tightly on the inside of winding.

This structure has a problem that rewinding structure is very hard, can produce reaction force to arcuate member, and hydraulic pressure is difficult to put down Weighed this reaction force, and disadvantageous changes are occurred for the posture for causing arcuate member by this, then influences the direction that unreels of winding, influences to add Working medium amount.

Therefore, it is necessary to a kind of new wrap-up is provided to solve the above problems.

Utility model content

Main purpose of the present utility model is to provide a kind of wrap-up for improving and unreeling precision.

The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of wrap-up, including axially hollow master Axle, the harmomegathus bar being arranged in main shaft, the support set being sheathed on outside main shaft and the fixed block and multiple set around support set Harmomegathus block, connected between harmomegathus bar and support set by penetrating the bearing pin of main shaft, main shaft does not influence activity of the bearing pin in axial direction, often Multiple female skewbacks axially arranged along main shaft are equipped with the inside of one harmomegathus block, support set outer wall is provided with and female skewback one The public skewback of one matching.

Specifically, first baffle and second that can only be radially movable for limiting harmomegathus block is further fixed on the main shaft Baffle plate.

Specifically, the harmomegathus block is three.

Specifically, the outside of the fixed block is provided with entrainment groove.

Specifically, support set outer surface section is square.

Further, two cunning ridges parallel to axis are fixed with the support set, the inner side of the fixed block is provided with The chute slided for sliding ridge.

Specifically, the harmomegathus bar is retreated by Driven by Hydraulic Cylinder, hydraulic cylinder is fixed with main shaft relative position.

Further, the hydraulic cylinder connects harmomegathus bar by shaft coupling.

Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：

1st, the utility model ensure that the depth of parallelism of harmomegathus block action, kept away using the cooperation of multiple female skewbacks and male skewback Winding has ensured machining accuracy from there is warpage deviation when having exempted to unreel.

2nd, skidded when entrainment groove is avoided that band winding.

3rd, square support set profile can be manufactured conveniently.

4th, sliding ridge can prevent support set to be pivoted under the reaction force of band blowing.

5th, shaft coupling energy-conservation plays buffering, vibration damping and the work for improving shafting dynamic property in the power transmission of high-speed overload With.

Embodiment

The utility model is described in further detail with reference to specific embodiment.

Embodiment：

As shown in Figure 1 to Figure 3, a kind of wrap-up of the present utility model, including axially hollow main shaft 1, it is arranged in master Harmomegathus bar 2 in axle 1, the support set 3 being sheathed on outside main shaft 1 and the fixed block 4 set around support set 3 and multiple harmomegathus blocks (the first harmomegathus block 5a, the second harmomegathus block 5b and the 3rd harmomegathus block 5c), harmomegathus bar 2 are driven by hydraulic cylinder 21 and retreated, hydraulic cylinder 21 fix with the relative position of main shaft 1, are connected between harmomegathus bar 2 and support set 3 by penetrating the bearing pin 31 of main shaft 1, the not shadow of main shaft 1 Activity of the bearing pin 31 in axial direction is rung, multiple female skewbacks 51 axially arranged along main shaft 1 are equipped with the inside of each harmomegathus block, The outer wall of support set 3 is provided with the male skewback 32 matched one by one with female skewback 51, is further fixed on main shaft 1 for limiting harmomegathus block 5a, 5b, 5c can only be radially movable first baffle 11 and second baffle 12.Winding be by fixed block 4 and all harmomegathus block 5a, What the roller shape structural outer surface " expansion " that 5b, 5c are combined into was fixed.Main shaft 1 limits harmomegathus bar 2 and support set 3 can only be in axial shifting It is dynamic.When hydraulic cylinder 21 drives harmomegathus bar 2 to move forward, support set 3 drives all public skewbacks 32 to move forward together, and because harmomegathus block 5a, 5b, 5c can only be moved radially under the limitation of first baffle 11 and second baffle 12, that is to say, that all female skewbacks 51 It can only move radially, so the radial direction that the axial advancement of male skewback 32 can change into female skewback 51 inside contracts, all harmomegathus block 5a, 5b, 5c are inside contracted, and now wrap-up reduces, and can be used for the loading and unloading of instant rolled band；Conversely, when hydraulic cylinder 21 drives harmomegathus bar When being moved after 2, swollen outside all harmomegathus block 5a, 5b, 5c, now wrap-up swells, and can be used for fixing winding and carry out material retractable. Because single harmomegathus block is fixed by female skewback 51 in column and support set 3, the section energy of the outer surface of harmomegathus block Ensure the depth of parallelism with the axis of support set 3, and the axis of support set 3 is exactly the axis of whole wrap-up, so winding is put It can guarantee that when going out and occur without warpage deviation, ensured machining accuracy.

As shown in figure 3, the outer surface section of support set 3 is square.So public skewback 32 is integrally fixed in plane, to manufacture The present apparatus is more convenient.

As shown in figure 3, the outside of fixed block 4 is provided with entrainment groove 41.It is clamped in the top insertion entrainment groove 41 of band Firmly, could so start winding and it is non-slip.

As shown in figure 3, being fixed with two cunning ridges 33 parallel to axis on support set 3, the inner side of fixed block 4 is provided with for sliding The chute (not marking) that ridge 33 slides.Fixed block 4 is constant above, and sliding ridge 33 can prevent support set 3 in band blowing It is pivoted under reaction force.

As shown in figure 1, hydraulic cylinder 21 connects harmomegathus bar 2 by shaft coupling 22.Shaft coupling 22 can be in the power of high-speed overload In transmission, play a part of buffering, vibration damping and improve shafting dynamic property.

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality New protection domain.
