Description
Technical field
A kind of pile tube production technology is the utility model is related to, especially a kind of spiral pipe pile production equipment, specifically
A kind of energy Varying-thickness variable diameters super long spiral pipe production line pre-bending guide plate.
Background technology
It is well known that pile tube starts to produce early 20th century in Europe, and rapidly in particularly flourishing industry all over the world
Change country to be used widely.In the 1950s, China is first in railroad bridge cofferdam construction, by bridge office of the Ministry of Railways from
Former Soviet Union's introducing and employment.Due to being influenceed by cheap land resource and human resources, domestic production in addition is substantially at blank shape
State, as the overlength pile tube of metal building material, the application in China is still very slow with developing.With the quick hair of China's economy
Exhibition, all kinds of quick, efficiently, environmentally friendly construction techniques are able to approve and developed, 20 end of the centurys, the steel sheet pile application work in China
Journey oneself have certain development.Due to its special construction, thus there is the advantages of unique:High intensity, light-duty, water isolating is good;
Durability is strong, and service life reaches 20-50;It is reusable, it is general to can be used 5-10 times;Environment protecting is notable, is constructing
In can greatly reduce the amount of fetching earth and the usage amount of concrete, effectively protect land resource;Function with stronger disaster relief and rescue,
Especially controlling flood, cave in, collapse, in the rescue and relief work of drift sand, taking effect especially fast；Construction is simple, duration shorten, construction cost
Compared with province.
Ocean engineering is increasingly popularized at present, carries out enclosing the length for needing pile tube among extra large, the marine implementation in cofferdam at deep-sea
Increasingly longer, especially depth is deep, it is desirable to and the load of carrying is just higher, but in the big of each place carrying of longitudinal direction
It is small and be change, wherein the power in the place carrying of land and sea junction is maximum, if carrying out calculated thickness according to maximum point value, due to
Steel are also different in length direction unbalance stress, carrying thickness requirement, it is necessary to work out in length direction according to stress feelings
Condition determines the pile tube of the Varying-thickness of thickness.So intensity requirement can be met, and can saves material in large quantities, has very
High frequent benefit and social benefit.
If using the pile tube of this Varying-thickness, steel using amount will be substantially reduced, can save 20 ~ 30%, it is cost-effective, have
The Social benefit and economic benefit of display.And as far as the applicant is aware, there is no one kind to produce Varying-thickness super long spiral pile tube at present
Equipment it is available.And one of key as such production equipment is how to ensure that strip is entering the preceding both sides production of forming machine
Raw required bending, and prevent that steel band generation upwarps in bending process, it is therefore necessary to the pre-bending guide plate of design specialized.
Utility model content
The purpose of this utility model is for needing to carry out steel band both sides in advance in the production of Varying-thickness super long spiral pile tube
Bending and preventing drives steel band the problem of upwarping in bending process, design it is a kind of can Varying-thickness variable diameters super long spiral steel pipe's production
Line pre-bending guide plate.
The technical solution of the utility model is：
A kind of spiral steel pipe production line pre-bending guide plate, it includes fixed support 2, and fixation is provided with fixed support 2 and is led
To plate 1, it is characterized in that the both sides of described fixed guide plate 1 are respectively provided with a pre-flanging guide wheel group 3, two sides of steel band are entered
Enter to be formed between pre-flanging guide wheel group the shape of inside bending, fixed guide plate 1 is pressed downward steel band and forms deformable supports side, solid
The discharging side for determining guide plate 1 is provided with movable guide plate 5, and the top of movable guide plate 5 is provided with the groove that can adjust its height
Beam 6.
Gap between two guide wheels of described pre-flanging guide wheel group 3 is adjustable, is needed with adapting to different-thickness sheet metal bending
Will.
The quantity of described movable guide plate 5 is three, pushes down the centre and two sides of steel band respectively.
Roller is installed to reduce steel band in the one side that described movable guide plate 5 and fixed guide plate 1 contacts with steel band
The frictional force passed through.
The beneficial effects of the utility model：
The utility model solves production and is badly in need of, and sliding port can be adjusted according to plank thickness and highly meets different bending chis
Very little requirement.
The utility model is simple in construction, easily manufactured, and mounting and adjusting is convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 top view.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1-2.
A kind of spiral steel pipe production line pre-bending guide plate, it includes fixed support 2, and fixation is provided with fixed support 2 and is led
To plate 1, the both sides of described fixed guide plate 1 are respectively provided with a pre-flanging guide wheel group 3, and two sides of steel band enter pre-flanging
The shape of inside bending is formed between guide wheel group.Gap between two guide wheels of pre-flanging guide wheel group 3 is adjustable, to adapt to difference
Thickness sheet metal bending needs.Movable guide plate 5, the top peace of movable guide plate 5 are installed in the discharging side of fixed guide plate 1
Equipped with the groove beam 6 that can adjust its height, as shown in Figure 1.When it is implemented, the quantity of described movable guide plate 5 is three, point
The centre and two sides of steel band are not pushed down, as shown in Figure 2.What described movable guide plate 5 and fixed guide plate 1 contacted with steel band
Roller is installed to reduce the frictional force that steel band passes through on simultaneously.In order to prevent sideslip in steel band moving process, in support both sides
Should also be provided with prevents the edger roll 4 of sideslip.
The utility model is not directed to partly same as the prior art or can realized using prior art.
