Abstract

A wire winding device belongs to the steel rolling equipment technical field. To be solved technical problems are to overcome the oil cylinder leakage defect after the seal failure. The Technical proposals are: the utility model comprises an outer cylinder, an inner cylinder, a protecting cover, an elevator, a drive device and a swing cylinder; wherein, the inner cylinder is provided a mandril and a support disk, the protecting cover is linked with the elevator and the swing cylinder by the linking arm whose one end is rotated and supported on the piston rod of the elevator cylinder; the swing cylinder is supported fixed on the piston rod of the elevator cylinder; the piston rod of the swing cylinder is movably linked with the linking arm. After the fixed linking of the protecting cover with the elevator cylinder is change into the support rotating linking, the piston rod will not rotate with the protecting cover, when the cover is driven to rotate by the swing cylinder, which completely eliminates the seal worn failure and leakage defects cause by piston rotating with the cover in the original fix linking structure; the cover movement is reliable and the level of rotating swing resistance is small. The utility model has a simple structure, which is suitable for the wire rolling production line.

Description

A kind of wire rod wrap-up

Technical field

The utility model relates to the rolling facility after the wire rod rolling, belongs to the mechanical equipment of steel rolling technical field.

Background technology

To twine rolling by wrap-up after wire rod rolling is intact.Wrap-up generally is made up of urceolus, inner core, protecting cover etc.The inner core swivel bearing has in the inner core along twining the fixing plug of circle in urceolus, and protecting cover covers on the inner core, and high temperature wire rod lead-in groove is arranged on the protecting cover.Twine when initial, protecting cover descends near the pallet of interior tube bottom, and rolling good high temperature wire rod enters inner core by lead-in groove, along with the rotation of inner core and plug is wrapped on the plug.Inner core stopped the rotation when wire rod was wound to the plug upper end, protecting cover is rising under the driving of hoist cylinder above the inner core, leave the nozzle of inner core after under oscillating oil cylinder drives, horizontally rotating certain angle then, the pallet of interior tube bottom rises under the driving of hoist cylinder, and the wire rod that winds is lifted out inner core.In this kind wrap-up, piston rod is connected to fixed connection structure in protecting cover and the hoist cylinder, when oscillating oil cylinder promotion protecting cover horizontally rotates, the piston rod of hoist cylinder rotates with the protecting cover level of synchronization, so in using, often because of the frequent rotation wear out failure of piston rod, leaking appears in oil cylinder after the seal failure, can't operate as normal in the sealing of the piston rod of hoist cylinder and the sealing between the oil cylinder, cylinder body end.For guaranteeing the operation of wrap-up normal reliable ground, must improve existing wrap-up.

Summary of the invention

Technical problem to be solved in the utility model is that existing wrap-up is improved, and makes it overcome above-mentioned defective.

Technical problem to be solved in the utility model realizes with following scheme:

A kind of wire rod wrap-up, urceolus, inner core, protecting cover, drive unit and lifting, oscillating oil cylinder are arranged in the formation, plug and pallet are arranged in the inner core, protecting cover links to each other with lifting, oscillating oil cylinder by linking arm, its improvement is, one end swivel bearing of described linking arm 12 is on the piston rod of hoist cylinder 10, and described oscillating oil cylinder 11 is fixed on the piston rod of hoist cylinder 10 by supporting 14, and the piston rod of oscillating oil cylinder and linking arm flexibly connect.

Above-mentioned wire rod wrap-up, described linking arm 12 passes through the rolling bearing swivel bearing on the piston rod of hoist cylinder 10.

After the utility model becomes the swivel bearing syndeton with the fixed connection structure of protecting cover and hoist cylinder, when protecting cover rotates under oscillating oil cylinder drives, the piston rod of hoist cylinder is not in company with rotation, the defectives such as sealing wear leakage failure that piston rod causes with the protecting cover rotation in original fixed connection structure have thoroughly been eliminated, it is reliable to have the protecting cover lifting, it is little to horizontally rotate the swing resistance, and characteristics such as easy to implement simple in structure are suitable for installing and using in the wire rod rolling line.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the protecting cover vertical view among Fig. 1;

Fig. 3 is that the K of Fig. 2 is to view.

The specific embodiment

Consult accompanying drawing, 1 is that urceolus, 2 is that inner core, 3 is that protecting cover, 4 is pallet among the figure, 5,6,7 motor and the bevel gears that are respectively in the drive unit, 8 for frame, 9 for the hoist cylinder of pallet, 10,11 is respectively the lifting and the oscillating oil cylinder of protecting cover, 12 be linking arm, 13 for rolling bearing, 14 for supporting, 15 being that high temperature wire rod guide groove, 16 is a plug.During the utility model work, motor 5 drives the inner core rotation by

bevel gear

6,7, the plug 16 that is fixed in during rotation on the inner core chassis rotates thereupon, twine when initial, protecting cover 3 drops to interior tube bottom, tube bottom was begun to twine by the bottom in the high temperature wire rod was entered by lead-in groove 15, when being wound to the plug upper end, inner core stops the rotation, protecting cover 3 rises under the driving of hoist cylinder 10, the back oscillating oil cylinder 11 that puts in place of rising drives protecting covers 3 and horizontally rotates about 70 and leave the inner core nozzle, and pallet 4 rises under the driving of hoist cylinder 9 wire coil is held out inner core.

Still consult accompanying drawing, main improvement of the present utility model is that protecting cover 3 adopts the swivel bearing syndeton with the piston rod of hoist cylinder 10.As shown in the figure, an end of linking arm 12 links to each other with protecting cover 3, and the other end is by the piston rod upper end of rolling bearing 13 swivel bearings at hoist cylinder 10, and linking arm 12 can horizontally rotate around the piston rod of hoist cylinder 10.Oscillating oil cylinder 11 is owing to need with the protecting cover synchronization lifting and drive protecting cover to horizontally rotate, so set up support 14 for 11 times at oscillating oil cylinder, oscillating oil cylinder is fixed on the piston rod of hoist cylinder 10 by supporting 14, when the piston rod of hoist cylinder 10 rises, linking arm 12 and support 14 are risen thereupon synchronously, rise put in place after, the piston rod of oscillating oil cylinder 11 stretch out or when bounce back by linking arm 12 driving protecting covers 3 left or the right side horizontally rotate.Keeping making piston rod no longer with the protecting cover rotation under the constant prerequisite of protecting cover lifting, rotary oscillation function, rotate the various use disadvantages that cause so can eliminate piston rod.
