Description
Technical field
The utility model relates to roughing mill apparatus field, in particular to a kind of roughing mill main shaft flat head sleeve.
Background technique
The rolling operation of roughing mill is to impart power to roll by the homalocephalus connecting with roll by flat head sleeve, to drive
Roll rotation, existing flat head sleeve inner hole include a pair of of arc surface and a pair of of plane, and arc surface is opposite two-by-two, plane also two two-phase
It is right, and wearing plate is provided in plane.But flat head sleeve has the disadvantage that in use
One, wearing plate is fixed using two bolts and a positioning pin, due to being acted on for a long time by alternating stress load, bolt
It often fractures, causes wearing plate and flat head sleeve ontology to generate relative motion during transmitting torque centered on positioning pin, make
At the abrasion of flat head sleeve ontology, eventually leads to wearing plate and flat head sleeve gap increases, conjunction bolt can not be replaced, can not finally be passed
Torque delivery is forced lower machine, generates massive losses；
Two, with the continuous abrasion in use process, the gap between roller palm and flat head sleeve constantly increases, and causes water
Vapour can be directly entered in the gap, heavy corrosion flat head sleeve inner hole；
Three, when replacing roll, especially when roll, flat head sleeve are all new products, roller palm and flat head sleeve inner hole it
Between form confined space, when filling roller, roller palm is inserted into flat head sleeve inner hole, makes to form confined space in inner hole, and with roll
The air of homalocephalus being inserted into it gradually forms positive pressure, causes dress roller difficult；When taking out roller, roller palm is taken out from flat head sleeve inner hole
Out, the air in confined space forms negative pressure with the gradually extraction of roller palm, causes to take out roller difficulty.
Summary of the invention
The purpose of this utility model is to make improvement and innovation for shortcoming and defect present in background technique, provides one
Kind of roughing mill main shaft flat head sleeve, the flat-head sleeve for rough rolling mill have stronger waterproofness, can improve wearing plate positioning accuracy and
Reliability reduces flat head sleeve sharp wear caused by wearing plate play, extends the service life of flat head sleeve, and can solve homalocephalus
The problem for covering dress caused by internal cause air positive/negative-pressure, taking out roller difficulty.
To achieve the above object, the technical solution of the utility model is: a kind of roughing mill main shaft flat head sleeve, including flat head sleeve
Ontology, flat head sleeve ontology front end have been bolted outer centering ring, and flat head sleeve ontology front end is additionally provided with inner hole,
The inner hole bottom is fixed with inside centering ring, and the outer centering ring front end has been bolted gland and sealing ring, described close
Seal is symmetrically arranged with two pieces of wearing plates between gland and outer centering ring on the inside of the inner hole, on the flat head sleeve ontology
Offer stomata.
The internal diameter of the gland, sealing ring and outer centering ring is successively from small to large in one of the embodiments:
Sealing ring, outer centering ring and gland.Sealing ring is directly contacted with roll, is sealed the gap between roller palm and flat head sleeve, is kept away
Exempt from steam and enters the corrosion for causing flat head sleeve in flat head sleeve inner hole.
The wearing plate section is dovetail-shape in one of the embodiments,.It is further increased using dove tailed wear plate
The positioning accuracy of wearing plate, effectively controls mobile trend of the wearing plate in flat head sleeve ontology.
Positioning pin there are two being opened up on the wearing plate in one of the embodiments, and be arranged in wearing plate central axes
On, it is also set up on the wearing plate there are four fastening bolt, and be symmetricly set on the two sides of wearing plate central axes.It is fixed using two
Position pin four bolts of cooperation, improve the fastness of wearing plate, reduce the degree of wear of wearing plate, and then improve making for flat head sleeve
Use the service life.
The stomata is connected to inner hole bottom in one of the embodiments, and is at least arranged two, also sets on the stomata
It is equipped with rubber stopper.By the way that stomata is arranged on flat head sleeve ontology, when solving replacement roll, air in flat head sleeve inner hole just,
Dress caused by negative pressure takes out roller difficult problem；By stomata, dry oil lubrication can be added in flat head sleeve inner hole, alleviates flat head sleeve
With the abrasion of roller palm, the service life of flat head sleeve is further extended.Rubber stopper is extracted when dismounting roll, makes homalocephalus
Confined space can not be formed between set inner hole and roller palm, and can prevent steam from entering in flat head sleeve inner hole.
The advantages of the utility model and the utility model has the advantages that
The utility model is sealed using sealing ring, and avoidable steam is directly entered in flat head sleeve inner hole, increases flat head sleeve
Waterproofness, reduce the corrosion of flat head sleeve inner hole；The utility model uses the wearing plate of swallowtail-shaped structure, improves wearing plate
Positioning accuracy, effectively control mobile trend of the wearing plate in the ontology of flat head sleeve, meanwhile, matched using two positioning pins
Four bolts are closed, the fastness of wearing plate is improved, reduce the degree of wear of wearing plate, and then improve the use longevity of flat head sleeve
Life；The utility model is by being arranged stomata on flat head sleeve ontology, air when solving replacement roll, in flat head sleeve inner hole
Dress caused by positive and negative pressure takes out roller difficult problem；By stomata, dry oil lubrication can be added in flat head sleeve inner hole, alleviates homalocephalus
The abrasion of set and roller palm, further extends the service life of flat head sleeve；The utility model on stomata by being arranged rubber
Rubber plug extracts rubber stopper when dismounting roll, makes that confined space can not be formed between flat head sleeve inner hole and roller palm, and energy
Prevent steam from entering in flat head sleeve inner hole.
