The utility model discloses change curved side panels into bolted connection with the welding of being connected by the conventionality between the round pin axle, improved joint strength and working property, be favorable to recycling and life's extension of pole body to the convenient to detach maintenance.
Description
Technical field
The utility model is related to a kind of dummy bar structure, more particularly to a kind of board-like rigid leading ingot club body attachment structure.
Background technology
Dummy bar is the vitals on conticaster, is made up of dummy bar head and shaft.The shaft of board-like rigid dummy bar is
Plank frame, we are also referred to as clamp region, generally arc, are made up of 2 groups of curved plates be arrangeding in parallel；According to conticaster machine
Its arc radius of type difference are also different, and shaft is more than ten meters.Therefore curved plate is divided into multistage again, adopts between every section of shaft
It is weldingly connected with bearing pin.The rigidity of board-like rigid dummy bar is big, lightweight, easily manufactured, in straight carbon steel and the little side of low-alloy steel
It is widely applied in base continuous casting.
At present, it is fixedly connected by bearing pin between 2 pieces of arc side plates of board-like rigid leading ingot club body, bearing pin and curved side
Connected using welding manner between plate.Because the material of arc side plate is 42CrMo, welding performance is bad, after not only needing heating
Can weld, and welding process requirement is strict, and welding quality is difficult to ensure that；Especially when producing in winter, after often welding also
Do not assemble weld seam just to have ftractureed, and cannot repair, cause yield rate low, production cost is high.
The demand for development of steel and iron industry constantly reduces production cost, draws steel equipment raw for the entirety for improving continuous casting machinery
Produce capacity great, therefore the requirement from quality, cost, performance is all improved constantly.The rigidity that at present country uses is drawn
Spindle blade generally existing service life is short, the problem that production efficiency is low；At least one month after use, up to two or three months, even
Connecing hole will deform, and cause dummy bar entirety radian to become big.Radian becomes big dummy bar, it is impossible to match with crystallizer aborning
Close, it is impossible to smoothly into crystallizer, and because radian becomes big, when drawing steel bleedout is easily caused, make process of billet withdrawal very unstable.
The content of the invention
The utility model provides a kind of board-like rigid leading ingot club body attachment structure, by between arc side plate and bearing pin
Connect and bolt connection be changed to by conventional welding, improve bonding strength and service behaviour, be conducive to shaft recycle and
The prolongation of service life, and maintenance easy to disassemble.
In order to achieve the above object, the utility model employs the following technical solutions realization：
A kind of board-like rigid leading ingot club body attachment structure, the shaft is made up of multistage segmental arc shaft；Every section of arc
Section shaft includes 2 pieces of parallel and symmetrically arranged arc side plates, and arcuately the longitudinal center of side plate is uniformly provided with multigroup connection
Mechanism；Every group of bindiny mechanism is constituted by bearing pin, bolt and gland, and 2 pieces of arc side plates open up respectively pin in correspondence link position
Axis hole, the outside of pin shaft hole sets respectively gland installing hole；The two ends of bearing pin are located in respectively in the pin shaft hole of both sides arc side plate,
Bearing pin is multidiameter structure, and mid portion is with diameter greater than the diameter for stretching into bearing pin bore portion；Set gland in gland installing hole, 2
Individual bolt is each passed through one end that corresponding gland is fixed on bearing pin.
The gland is circular cover.
The bolt is dormant bolt.
Compared with prior art, the beneficial effects of the utility model are：
1) avoid because special substance welding quality does not pass a test the mass defect for causing, improve the company between arc side plate
Connect intensity and reliability；
2) bearing pin connecting hole stress is improved, and is unlikely to deform compared with conventional connected mode, is conducive to holding to draw
The optimal radian of spindle blade, extends the service life of dummy bar；
3) using being detachably connected mode, shaft can Reusability, and convenient maintenance.

Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
A kind of board-like rigid leading ingot club body attachment structure described in the utility model, the shaft is by multistage segmental arc shaft
Composition；Every section of segmental arc shaft includes 2 pieces of parallel and symmetrically arranged arc side plates 1, and arcuately the longitudinal center of side plate 1 is equal
It is even to be provided with multigroup bindiny mechanism；Every group of bindiny mechanism is constituted by bearing pin 2, bolt 4 and gland 3, and 2 pieces of arc side plates 1 are in correspondence
Link position opens up respectively pin shaft hole, and the outside of pin shaft hole sets respectively gland installing hole；The two ends of bearing pin 2 are located in respectively both sides
In the pin shaft hole of arc side plate 1, bearing pin 2 is multidiameter structure, and mid portion is with diameter greater than the diameter for stretching into bearing pin bore portion；
3,2 bolts 4 of gland are set in gland installing hole and is each passed through one end that corresponding gland 3 is fixed on bearing pin 2.
The gland 3 is circular cover.
The bolt 4 is dormant bolt.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its design in addition equivalent or change, all should cover within protection domain of the present utility model.
