Description

The special-purpose apparatus for bending of corner ground connection band iron
Technical field
The utility model relates to a kind of device that sheet metal is carried out to bending, specifically a kind of device to the bending of strip sheet material broad ways.
Background technology
In the work progress of power system, through the embedded underground ground connection of being everlasting, lead iron as main grounding grid ground connection, to guarantee the contact area of power system.Ground connection is led the mild steel lath (being commonly called as band iron) that iron is generally wide 100mm left and right, thick 10mm left and right, while laying ground connection wire guide, is band iron to be tiled and is connected to each other be integrated, and is then embedded in soil, to guarantee good ground connection.On building, need the earth connection of the power equipment of ground connection also will be connected on the band iron that is embedded in underground main grounding grid with band iron simultaneously.In the work progress of ground connection band iron, being connected to each other between band iron need to have certain lap of splice, in the total length of overlap joint, connects by welding manner again.Band iron in building, in process of deployment, needs to walk around the various pipelines such as water pipe or other electric power facility sometimes, therefore also needs band iron to be bent into certain camber.And attractive in appearance for what construct, the camber of band iron is generally embayment on the width of band iron, has so just increased the difficulty of bending.
When making crooked ground connection band iron in the past, conventionally with sectional straight band iron overlap welding, be connected into the band iron with camber, so not only not attractive in appearance, but also the expense material of taking a lot of work; And the band iron that need to turn in job site is a lot, and situation complexity is uncertain, can not adopt measurement size Hou Dao special manufacturer to return home and process the mode of crooked band iron, be all generally field fabrication, but do not have at present field fabrication by width, to bend the equipment of band iron.
Utility model content
The utility model technical issues that need to address are to provide a kind of simple in structure, can meet the apparatus for bending to band iron that job site is used, and it can be converted into band iron along any camber of band iron width.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The special-purpose apparatus for bending of corner ground connection band iron, comprise a bearing, described bearing mainly consists of two block plates, and the upper middle position of two steel plates is connected to one and a hydraulic cylinder is set on connecting portion, and the two ends, bottom of two steel plates are connected and fixed two steel plates by contiguous block respectively; Between two steel plates of the inside of bearing, below hydraulic cylinder, a dynamic model at bearing sliding is set, the main body of dynamic model is also two block plates, between inside two block plates of dynamic model, be provided with the internal mold that bottom is external arc, the upper end of dynamic model is fixedly connected with internal mold, internal mold is connected with the hydraulic stem of hydraulic cylinder, distance between two block plates of dynamic model is corresponding with the thickness of bent band iron, in the lower end of dynamic model, is provided with carrying bolt.
Further improvement of the utility model is: between two contiguous blocks of described bearing bottom, be also provided with some support axis holes that are arranged symmetrically with between two.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
Apparatus for bending of the present utility model can carry out bending to the width of band iron, and band iron is converted into along any camber of band iron width.It is simple and light, can meet the demand of electric power construction field convenient in carrying, can need to produce the ground connection band iron of different bent angles according to scene.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
The special-purpose apparatus for bending of corner ground connection band iron, comprise a bearing 2, bearing 2 mainly consists of two block plates, the main-vision surface of steel plate is trapezium structure, and the upper middle position of two trapezoidal steel plates is connected to one, and on the position that connects two steel plates, a hydraulic cylinder 1 is set, a contiguous block 5 is placed respectively at the two ends, bottom of two steel plates, and with bolt, contiguous block 5 is fastened between two steel plates, contiguous block 5 and bolt are by the location, bottom of two steel plates of bearing, the structure that the bottom of two steel plates is hollow; Between two steel plates of the inside of bearing 2, below corresponding hydraulic cylinder, a dynamic model 3 is set, dynamic model 3 can slide up and down cooperation in bearing 2, the main body of dynamic model 3 is also two block plates, between inside two block plates of dynamic model 3, be provided with internal mold 4, the bottom of internal mold 4 is the shape of external arc, the upper end of dynamic model 3 is fixedly connected with by connecting bolt 8 with internal mold 4, internal mold 4 upper ends are connected with the hydraulic stem 7 of hydraulic cylinder 1, distance between two block plates of dynamic model 3 is corresponding with the thickness of bent band iron, in the lower end of dynamic model 3, is provided with carrying bolt 10.When needs bend ground connection band iron, the band iron of strip is vertically inserted in dynamic model 3, make the bending position of band iron of strip between carrying bolt 10 and internal mold 4, as shown in Figure 1, then primer fluid cylinder pressure, makes dynamic model 3 drive the band iron 6 of strip to move downward, band iron touches after contiguous block 5, hydraulic cylinder continues to press down, and the band iron 6 of strip bends in the interior broad ways of dynamic model 3, is bent into the bent plate with certain radius.Between bearing 2 bottom two contiguous blocks 5, be also provided with some support axis holes 9 that are arranged symmetrically with between two, when needs bend shorter band iron, or in the time of need to bending the less band iron of angle, supporting the interior insertion back shaft of axis hole 9, when moving down supported axle while touching back shaft, band iron 6 props up, along with the band iron that moves down strip of dynamic model 3 is by bending.As shown in Figure 2, use apparatus for bending of the present utility model curved band iron can be bent in 90 ° flat curved, when being connected with the horizontal band iron of main grounding grid, the flat curved band iron of 90 ° is ridden on the horizontal band iron of main grounding grid, can guarantee contact length and the contact-making surface of curved band iron and horizontal band iron, by three welding, can be connected firmly, it conducts electricity very well, the making construction technology that can promote grounded screen, has improved processing quality.During ground connection band iron on making building, also can guarantee the camber requirement of band iron.
