Abstract
The invention discloses a bending device special for corner grounding flat bars and applied to bending elongated plates in the width direction. The bending device comprises a support. The middle of the top of the support is fixedly connected in a whole, and a hydraulic cylinder is disposed on the connected part. Two ends of the support are fixedly connected to two steel plates through connecting blocks respectively. A moving die sliding on the support is disposed inside the support below the hydraulic cylinder. The moving die is mainly made of two steel plates. An external arc bottom of an inner die is fixed between the steel plates inside the moving die. The inner die is connected with a hydraulic bar of the hydraulic cylinder. The distance between the steel plates of the moving die is equal to the thickness of a bent flat bar. A support bolt is disposed at the lower end of the moving die. A plurality of support shaft holes in pairwise symmetry are formed in the lower portion of the support between the two connecting blocks. The bending device has the advantages that the flat bar is bent in the width direction, the flat bar can be optionally bent along the width direction, the bending device is simple and light, and the requirements for carrying and production of grounding flat bars different in bent angle on power construction sites can be met.
Description
Technical field
The present invention 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, lead iron as main grounding grid ground connection through the embedded underground ground connection of being everlasting, 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 the ground connection wire guide, is band iron to be tiled and is connected to each other be integrated, and then is 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, on the total length of overlap joint, by welding manner, connects again.Band iron in building, in process of deployment, needs to walk around various pipelines or other electric power facilities such as water pipe sometimes, therefore also needs band iron is bent into to 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, usually 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 the situation complexity is uncertain, can not adopt after measurement size the mode of the crooked band iron of processing of returning home to special manufacturer, be all generally field fabrication, but do not have at present field fabrication to bend the equipment of band iron by width.
Summary of the invention
The technical issues that need to address of the present invention 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 solution adopted in the present invention 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; Below hydraulic cylinder, a dynamic model at bearing sliding is set between two steel plates of the inside of bearing, the main body of dynamic model is also two block plates, be provided with the internal mold that bottom is external arc between inside two block plates of dynamic model, 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 present invention is: also be provided with some support axis holes that are arranged symmetrically with in twos between two contiguous blocks of described bearing bottom.
Owing to having adopted technique scheme, the technological progress that the present invention obtains is:
Apparatus for bending of the present invention 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 present invention 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 location, the bottom of two steel plates of bearing, the structure that the bottom of two steel plates is hollow; Below corresponding hydraulic cylinder, a dynamic model 3 is set between two steel plates of the inside of bearing 2, dynamic model 3 can slide up and down cooperation in bearing 2, the main body of dynamic model 3 is also two block plates, be provided with internal mold 4 between inside two block plates of dynamic model 3, the shape that the bottom of internal mold 4 is 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 the ground connection band iron, the band iron of strip vertically is 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 the primer fluid cylinder pressure, move downward the band iron 6 of dynamic model 3 drive strips, after band iron touches 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.Also be provided with some support axis holes 9 that are arranged symmetrically with in twos between bearing 2 bottom two contiguous blocks 5, when needs bend shorter band iron, while perhaps needing to bend the less band iron of angle, supporting the interior insertion back shaft of axis hole 9, when band iron 6 moves down supported axle while touching back shaft, prop up, along with the band iron that moves down strip of dynamic model 3 by bending.As shown in Figure 2, use that apparatus for bending of the present invention is curved can be bent into band iron 90 ° flat curved, when being connected with the horizontal band iron of main grounding grid, the flat curved band irons of 90 ° are 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, can be connected firmly by three welding, it conducts electricity very well, can promote the making construction technology of grounded screen, improve processing quality.During ground connection band iron on making building, also can guarantee the camber requirement of band iron.
