Description
Technical field
Embrace circular knitting machine automatically the present invention relates to a kind of adjustable steel coils, specifically a kind of centreless coil of strip to after annealing into
The equipment of row inner circle full circle belongs to steel manufacture process auxiliary process equipment technical field.
Background technology
Cold-rolled products are the fine work in steel, belong to high-end product, have and process fine, technology-intensive, technique chain length, kind
The features such as various, widely used.World Iron ＆ Steel industrial development practice have shown that, with socio-economic development, cold-rolled products are in steel
Proportion in total quantity consumed is being continuously improved, and plays increasingly important role.
Heat treatment is the important procedure in cold rolling production after cold rolling, and cold-reduced sheet is mostly mild steel, is heat-treated after rolling usual
For recrystallization annealing, the property that cold-reduced sheet is reached by recrystallization annealing to be reduced the hardness of steel, eliminate cold work hardening, improve steel
It can, restore the purpose of the plastic deformation ability of steel.In entire cold-rolled steel coils heat treatment process, it usually needs by multiple
Annealing repeatedly needs uncoiling between annealing and batches operation.To ensure that the coil of strip after annealing can smoothly put on reel of uncoiler, protect
The circularity for holding coil of strip inner circle is particularly significant.However, due to the thermal deformation in heat treatment process, coil of strip circularity will necessarily be by shadow
It rings.For this purpose, there are two types of common measures：First, the inner circle in coil of strip adds in steel bushing core, to ensure the circularity of inner circle；Its
Two, the centreless coil of strip later to heat-treatment distortion carries out full circle.
In the first measure, the addition of steel bushing core can effectively prevent the deformation of inner circle, ensure the circularity of inner circle.So
And due to the difference of coil of strip and core thermal deformation in heat treatment process, the inside inevitably damaged close to core is several
The quality of laminate material, is allowed to form steel scrap, and so as to reduce the lumber recovery of steel, economic loss is caused to enterprise.
In second of measure, coil of strip inner circle is deformed without core after heat treatment.For this reason, it may be necessary to steel after cooling
Volume carries out full circle again.And full circle technique there is no general equipment can be used, and need to manufacture and design dedicated full circle equipment.Existing enterprise
Generally use is that a kind of manpower manual formula embraces circle device in industry.This armful circle device is mainly characterized by：Coil of strip is placed in firm banking
On arc pallet, there are adjustable arc plate in pedestal arc pallet both sides, and adjustable arc plate is driven by link mechanism, in pedestal arc support
Realize that circle of embracing downwardly and inwardly acts on plate, so as to fulfill the full circle of coil of strip.Its link mechanism is five-rod (containing rack),
Four revolute pairs, a prismatic pair and a higher pair, mechanism freedom 1 are included in mechanism.Mechanism be driven through leading screw and
The prismatic pair of nut composition realizes that driving member is screw.The apparent deficiency of the device is：The driving force of rotary screw rod relies on
Manpower, operation is laborious, and labour high intensity is big, inefficiency；Both sides adjustable arc plate is driven respectively by two independent leading screws, nothing
Method links, not only inefficiency, and operates poor to neutrality；Adjustable arc plate is simple sliding on pedestal arc pallet, mill
Damage is big, influences to embrace the precision of circle after abrasion；Adjustable arc plate is in direct contact with coil of strip, relative to the cunning of coil of strip work inwardly and downwardly
It is dynamic, it realizes and embraces circle, the sliding friction of arc panel and coil of strip causes surface damage to outer layer plate, influences lumber recovery；Mechanism can
Adjust poor performance, it is difficult to realize the full circle of various specifications coil of strip and reach armful Circular test of reasonably optimizing.
