Description
Technical field
The invention belongs to steel rolling technical field of tools, it is related to the processing and manufacturing of mill core component memorial archway, mainly
It is a kind of 20 roller memorial archway processing tools.
Background technology
Mill is using small roll neck, heavy reduction, high-speed rolling, reduction intermediate annealing number of times and reduces rolling pass
And rolling time, the hard alloy such as stainless steel, silicon steel can be rolled, while obtaining lower thickness and high accuracy and with good plate
The band of shape, is to obtain user finally to need the key equipment and technology needed for product.It is used as the core of monoblock type mill
Center portion part, mill housing is that 8 plum blossom-shaped through holes are processed in integral cast steel part, to install support roller device；With plum blossom
The vertical side of through hole is provided with the pyramid shape window by band.The scattered draught pressure passed on each support roller device, 8
Individual plum blossom-shaped lead to the hole site is absorbed by integral-rack.
The difficulty of processing of mill memorial archway is concentrated mainly in frame centre plum blossom cavity dimension and morpheme, due to two
Ten roller mill products are strip stainless steel, silicon steel and high-alloy steel, it is necessary to excellent plate shape and thickness requirement, so to 20
The size and Geometrical Tolerance Principle of roller mill memorial archway plum blossom hole have reached a kind of harsh degree, and particularly more than 1200mm is wide
Memorial archway plum blossom hole width needed for product considerably increases difficulty of processing up to more than 1700mm, as domestic 20 rollers of restriction
The manufacturing bottleneck of milling train.
The processing tool that current mill processing and manufacturing is used has two kinds：
One kind is, by reference for installation plate, frock foreboard, toolsetting plate on memorial archway, omnipotent milling cutter to be arranged on into boring machine ram
On, certain position is stretched out to ram after the completion of knife, is processed by workbench movement, this method can position plum blossom hole circle
Heart position, but ram cuts the collective effect of amount of deflection in after stretching out certain distance because of gravity factor and process, can go out
Existing cutter head sagging, can also produce trueness error in workbench moving process in addition, have impact on plum blossom hole size and morpheme
Tolerance, with certain risk；
Another is that the linkage of eight axles is processed, and plum blossom hole processing request can be being disclosure satisfy that to a certain degree, but need
Special purpose machine tool is wanted, and the cutter head structure complexity and installation accuracy of the linkage of eight axles require high, cost is larger.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide a kind of processing work of 20 roller memorial archway
Dress, it is ensured that 20 roller memorial archway plum blossom holes machine rear size and form and position tolerance reaches drawing requirement, and simple in construction, cost
It is cheap.
To achieve these goals, the technical scheme taken of the present invention is：
A kind of 20 roller memorial archway processing tools, including mill housing blank to be processed and for processing mill housing hair
The boring cutter of blank, boring cutter is arranged on boring bar, is mounted on processing template on the front-back of described mill housing blank, plus
It is provided with memorial archway plum blossom hole in work template, boring bar sequentially passes through processing template before mill housing blank, mill housing hair
Processing template behind blank and mill housing blank, the boring cutter is located at mill housing blank and the processing mould before it
Between plate.
The position of four drift angles of described processing template is provided with multiple screws, and screw will be processed through processing template
Template is fixed on mill housing blank.
Multiple fixed blocks, the fixed block difference are fixed with the preceding surface and rear surface of described mill housing blank
Positioned at processing template upper topside position and bottom position.
Multiple rackworks are installed on the described preceding surface of mill housing blank and rear surface, rackwork is supported respectively
Touch the upper topside in processing template and bottom.
Described rackwork includes the L-type fixed block that is fixed on mill housing blank and passes vertically through L-type consolidating
Determine the fastening bolt on block base.
The rackwork of described mill housing blank above or below has four, and two of which rackwork is contradicted
In the upper topside of processing template, remaining two contact at the bottom for processing template.
Described processing template, which is registered the license, is provided with lubricating sleeve in the plum blossom hole of mill, and the internal diameter of lubricating sleeve corresponds to the memorial archway of standard
Plum blossom hole aperture.
Trial cut plate is installed, the trial cut position of described trial cut plate is located on the preceding surface of described mill housing blank
Process between template and boring cutter.
Beneficial effects of the present invention：The processing tool of this 20 roller memorial archway of the present invention, with simple in construction, compact,
Install simple, low processing cost, strong adaptability and it is easy to maintenance the features such as, and the present invention applied processing large-scale by two
In the processing of ten roller mill memorial archways, the size and Geometrical Tolerance Principle of memorial archway plum blossom hole are ensure that, with good application
Prospect.
The present invention is described in further details below with reference to accompanying drawing.
