Description
Technical field
The present invention relates to a kind of support shaft of metal plate uncoiler, especially a kind of uncoiler support shaft.
Background technique
Uncoiler is the ancillary equipment of sheet metal process, and the uncoiling for metal coiled material is smoothed.Support shaft is the master of uncoiler
Functional component is wanted, is used to support and swelling coiled material inner hole.Most of existing uncoiler support shaft is the fan by radial motion
Shape block carrys out swelling coiled material, there is axial vertical masonry joint between sectorial block.Since coiled material uncoiling to last end can become due to stress
It obtains and is bent very much.Therefore often there is the problem of coiled material end is caught in vertical masonry joint in existing uncoiler, may cause component pine when serious
Dynamic failure.Meanwhile the surface curvature of support shaft sectorial block is fixed.But for the coiled material of different pore size, hole inner wall
Curvature is obviously different.Therefore, existing support shaft is when supporting different pore size coiled material, most indeed through sectorial block
High point forms single line contact, and this stability of strutting system is poor.Therefore, existing uncoiler support shaft, which exists, is easy by coiled material end
Catch on and support unstable problem.
Summary of the invention
The object of the present invention is to provide a kind of uncoiler support shafts.The present invention is not easy to be caught on by coiled material end, and
The present invention is more stable to the support of coiled material, and the board quality of output is more unified.
Technical solution of the present invention: a kind of uncoiler support shaft is equipped with master in sleeve including the sleeve with built-in space
Axis；Main shaft is threaded with nut, and the surface of nut is equipped with the first wedge block；
It further include supporting block, it is the sliding part on inclined-plane that supporting block lower end, which has end face, and sliding part passes through sleeve and first wedge
The cooperation of shape block is slided radially, and supporting block upper end has curved surfaces, and curved surfaces are equipped with the support chip of lifting；Along
Main-shaft axis direction, supporting block shift to install, and the no gap of the projection of supporting block in the axial direction, i.e., will not between supporting block
Form long vertical masonry joint.
In a kind of uncoiler support shaft above-mentioned, the first wedge block two sides are equipped with the second wedge block, the cunning
Dynamic portion two sides are equipped with the elevating lever radially slided in supporting block, and elevating lever is matched with the second wedge block, and the second wedge block
Slope be greater than the first wedge block；The top of elevating lever is arranged in the support chip.
In a kind of uncoiler support shaft above-mentioned, the reset spring with the cooperation of supporting block lower surface is arranged on elevating lever,
Stop nut is equipped with below reset spring.
In a kind of uncoiler support shaft above-mentioned, the both ends of the supporting block are equipped with lug, connect between lug and sleeve
It is connected to tension spring.
In a kind of uncoiler support shaft above-mentioned, the main shaft is connected with driving motor through disengaging type shaft coupling.
Compared with prior art, the present invention avoids the formation of long vertical masonry joint by supporting block that axile displacement is arranged, thus plate
Material will not catch on support shaft there is stress completely at uncoiling to end.Meanwhile supporting block of the invention is in main shaft band
While radius vector is to dilation, elevating lever and the cooperation of the second wedge block drive support chip lifting, the arc of support chip and supporting block
Corresponding curvature is consequently formed in shape surface ceiling for accumulation, can more preferably be bonded the inner wall of coiled material, forms multi-thread support, support is more
Stablize.So the present invention is not easy to be caught on by coiled material end, and the present invention is more stable to the support of coiled material, the plate of output
Quality is more unified.
In addition, in addition, structure of the invention is relatively easy, the structure that is driven based on screw rod to the abrasion of component relatively
It is small, thus the service life is longer.

Specific embodiment
Below with reference to embodiment, the invention will be further described, but is not intended as the foundation limited the present invention.
Embodiment: a kind of uncoiler support shaft is equipped with main shaft 10 in sleeve 11 including the sleeve 11 with built-in space；
Main shaft 10 is threaded with nut 12, and the surface of nut 12 is equipped with the first wedge block 13；
It further include supporting block 20, it is the sliding part 25 on inclined-plane that 20 lower end of supporting block, which has end face, and sliding part 25 passes through sleeve
11 slide radially with the cooperation of the first wedge block 13, and 20 upper end of supporting block has curved surfaces, and curved surfaces are equipped with and rise
The support chip 21 of drop；Along 10 axis direction of main shaft, supporting block 20 is shifted to install.
First wedge block, 13 two sides are equipped with the second wedge block 14, and 25 two sides of sliding part are equipped in supporting block
The elevating lever 22 radially slided in 20, elevating lever 22 are matched with the second wedge block 14, and the slope of the second wedge block 14 is greater than
First wedge block 13；The top of elevating lever 22 is arranged in the support chip 21.
It is arranged with the reset spring 23 with the cooperation of 20 lower surface of supporting block on elevating lever 22, is equipped with limit below reset spring 23
Position nut.
The both ends of the supporting block 20 are equipped with lug 24, are connected with tension spring between lug 24 and sleeve 11.
The main shaft 10 is connected with driving motor 15 through disengaging type shaft coupling.
Working principle:
Main shaft 10 is driven by driving motor 15, and sleeve 11 can actively be rotated by motor, or from turn on uncoiler
It is dynamic.When adjustment support diameter, sleeve 11 is not rotated, and main shaft 10 rotates.After adjustment, main shaft 10 and sleeve 11 are rotated synchronously,
Or main shaft 10 runs out of steam driven rotation.
When tuning up support diameter, with direction shown in Fig. 1, main shaft 10 is rotated, and nut 12 slides to the right, and supporting block 20 slides up
It is dynamic, it is achieved in the adjustment of base diameter.While sliding in supporting block 20, elevating lever 22 therein is also upper to be slided.Due to the second wedge
The slope of shape block 14 is greater than the first wedge block 13, and the displacement of support chip 21 is bigger than supporting block 20, and the two forms OQ t, by
This reaches different support curvature.Supporting block 20 is resetted by the tension spring of two sides lug 24, and elevating lever 22 then passes through and supporting block
The reset spring 23 of 20 lower surfaces cooperation resets.
