Abstract

The invention discloses an outside-line returning method for an aluminum foil mill, which comprises the following steps that: an underground return channel is adopted, a sleeve is discharged from an uncoiler onto a sleeve runout table (2); a sleeve (4) slides to a place in front of a sleeve holding device vertical to the sleeve runout table under gravity; a thrust device pushes the sleeve (4) to the front part of the sleeve holding device (3); the middle of the sleeve holding device (3) is provided with a shifting fork A (7) for shifting the sleeve to the rear part of the sleeve holding device, the tail end of the sleeve holding device (3) is provided with shifting fork B (8) for shifting the sleeve (4) to a sleeve runin table (5) vertical to the sleeve holding device (3); the sleeve slides to a place above an upper sleeve device (6) under gravity; and the upper sleeve device (6) lifts the sleeve (4) to a coiler, and thus the whole return process of the sleeve is completed. The method has the advantages of preventing the sleeve from occupying the space of the main machine of the mill in the return process and from influencing the rigidity of a rail support, achieving convenient use and maintenance and improving working efficiency.

Description

A kind of outside-line sleeve returning method that is used on the aluminium foil mill

Technical field

The present invention relates to the non-ferrous metal manufacture field, a kind of outside-line sleeve returning method that is used on the aluminium foil mill.

Background technology

At present, aluminium foil production all is the production of band sleeve, in order to enhance productivity, aluminium foil mill generally all disposes the sleeve return mechanism, and its function is to unload, transport and be installed on the coiling machine by the light sleeve (4) that unloads on the uncoiler that sleeve arrangement (1) will roll.The return trajectory of existing sleeve return mechanism (11) be installed in the milling train body under as accompanying drawing 1, must under the milling train body, pass when batching side so sleeve turns back to from the uncoiling side, there is following shortcoming in this design:

1) gusset that links of rail chair (10) is interrupted, and has weakened rail chair rigidity; Return used space in order to satisfy sleeve (4), the height of rail chair must increase, and has weakened the stability of rail chair.

2) in Rolling Production, generally on return trajectory (11), all need to lay in several sleeves, the ROLLING OIL that these sleeves can be fallen from milling train is drenched, this can reduce the frictional force between sleeve surface and aluminium foil, the phenomenon of skidding easily when coiling machine is set up initial tension, the throwing that influences coiling machine is opened.

3) sleeve is stuck in return course on the return trajectory sometimes, owing to be positioned at the below of milling train, the operating space is narrow and small, is not easy to handle, and influences production efficiency.

Summary of the invention

In return course, be stuck in problem on the return trajectory sometimes for solving sleeve, the invention provides a kind of outside-line sleeve returning method that is used on the aluminium foil mill, can make sleeve in return course, not take the space of milling train main frame, avoid the adverse effect of bringing because of ROLLING OIL; Use and easy to maintenance increases production efficiency.

For achieving the above object, the present invention adopts technical scheme as described below:

Described a kind of outside-line sleeve returning method that is used on the aluminium foil mill adopts a underground backward channel, does not take aboveground space; Its step is as follows:

1, by unloading sleeve arrangement sleeve is discharged on the sleeve runout table by uncoiler;

2, the design of sleeve runout table has the gradient of 1 degree, and sleeve relies on deadweight to slide into the place ahead of the sleeve storing unit vertical with the sleeve runout table;

3, the tail end arranged outside of sleeve runout table has thrust device, shifts sleeve onto with the sleeve storing unit front portion by thrust device;

4, middle being provided with of sleeve storing unit dialled the shift fork A that is put into sleeve storing unit rear portion with sleeve, and the end of sleeve storing unit is provided with dials the shift fork B that is put on the perpendicular sleeve approach table with sleeve;

5, the design of sleeve approach table has the gradient of 1 degree, and sleeve relies on deadweight to slide into upper bush device top,

6, the upper bush device is promoted to coiling machine with sleeve, has so just finished the overall process that sleeve returns.

Described a kind of outside-line sleeve returning method that is used on the aluminium foil mill unloads sleeve arrangement, sleeve runout table, sleeve storing unit, sleeve approach table and upper bush device and is composed in series.

Because adopt aforesaid technical scheme, the present invention has following excellent superiority:

1) sleeve does not take the space of milling train main frame in return course, can not influence the rigidity of rail chair, has brought rich space for simultaneously the optimal design and the pipe arrangement of milling train;

2) sleeve has had special backward channel, has avoided the adverse effect of bringing because of ROLLING OIL;

3) use and easy to maintenance has increased production efficiency.

The specific embodiment

Shown in Fig. 2,3: a kind of outside-line sleeve returning method that is used on the aluminium foil mill, adopt sleeve in milling train main frame district ZJQ, not returning, and design a underground backward channel for it specially, do not take aboveground space.The device of the outside-line sleeve returning method on this aluminium foil mill mainly contains and unloads sleeve arrangement (1), sleeve runout table (2), sleeve storing unit (3), sleeve approach table (5) and upper bush device (6) and be composed in series.

Its flow process is as follows during work: sleeve is discharged to by uncoiler on the sleeve runout table (2) through unloading sleeve arrangement (1), the design of sleeve runout table has the gradient of 1 degree, and sleeve (4) relies on deadweight to slide into the place ahead of the sleeve storing unit (3) vertical with the sleeve runout table; The tail end arranged outside of sleeve runout table has thrust device (9), shifts sleeve (4) onto with sleeve storing unit (3) first half by thrust device.

The centre of sleeve storing unit (3) is provided with sleeve dialled and is put into the latter half of shift fork A (7) of sleeve storing unit, the first half of sleeve storing unit and latter half ofly can deposit a plurality of sleeves simultaneously; The end of sleeve storing unit (3) is provided with dials the shift fork B (8) that is put on the perpendicular sleeve approach table (5) with sleeve (4).

When needs use sleeve, by shift fork B (8) sleeve is pushed on the sleeve approach table (5), same sleeve approach table (5) design has the gradient of 1 degree, rely on deadweight to slide into upper bush device (6) top by gradient sleeve (4), the upper bush device is promoted to coiling machine with sleeve (4), has so just finished the overall process that sleeve returns.
