Abstract

The utility model relates to a steel flat lateral bending device. The steel flat lateral bending device is used for bending lightening and grounding steel flat in a construction site. The steel flat lateral bending device comprises a substrate, a guide groove, a mold plate, a wrench, a trunnion, a pin and a lock plate. A snap ring groove is arranged on the mold plate. A groove with width corresponding to the thickness of the steel flat to be bent is arranged along a peripheral direction. The vertical dimension between the root portion of the groove and one edge of the snap ring groove, close to the center of the mold plate, corresponds to the width of the steel flat to be bent. The steel flat lateral bending device has the advantages that heating the steel flat and a battery are not required, and therefore bending can be achieved by manpower. The steel flat lateral bending device further has the advantage of being simple and flexible to operate, thereby being fit for bending the steel flat of a small amount in the construction site.

Description

The flat steel lateral-bending device
Technical field
The utility model relates to a kind of steel processing equipment, relates in particular to a kind of flat steel lateral-bending device.
Background technology
In chemical industry construction field electric device work progress, through commonly using band steel as the lightning protection connecting line, when laying, band steel needs band steel along lateral thrust 90 0Or other angle, the job site often takes oxy-acetylene welding the heating simmering and bending due to limited conditions, crooked band steel fold is serious in this way, the uniformity of the crooked size of band steel is relatively poor during batch jobs, owing to the band steel as ground connection is generally galvanized part, can destroy zinc coat during hot-working simultaneously.
Although the crooked special-purpose machinery of existing band steel such as bending roll machine exist on the market, because price is higher, volume is larger, it is applicable to produce the fragmentary operation of inapplicable on-the-spot small lot in enormous quantities.
The utility model content
The flat steel lateral-bending device that the utility model is provide for above-mentioned deficiency a kind of simple in structure, easy to operate, be applicable to the job site.
For achieving the above object, technical scheme that the utility model adopts comprises by pedestal, gathering sill, mould, spanner, the axle ear, the flat steel lateral-bending device that bearing pin and jam plate form, gathering sill, axle ear and pedestal are welded to connect, mould is rotationally connected by bearing pin and axle ear, spanner and mould are welded to connect, mould has its extended line not by the mould center and runs through the locking groove of mould thickness, the width of locking groove and the thickness of jam plate adapt, mould along the circumferential direction also has the groove that width and band steel thickness to be curved adapt, and the root of groove and locking groove are a bit larger tham the width of band steel to be curved near the vertical range between the limit at mould center.
As a kind of preferred version of the present utility model, described mould is provided with the scale that can show the band steel bending angle.
As another kind of preferred version of the present utility model, described jam plate is the gib head wedge.
Flat steel lateral-bending device of the present utility model need not band steel is heated, and need not power supply, can be with the moulding of band steel first order buckling by manpower, simple to operate flexibly, be specially adapted to job site small lot Flat steel bending.
Description of drawings

Fig. 2 is the utility model flat steel lateral-bending device working state schematic representation.
Fig. 3 is that flat steel lateral-bending device shown in Figure 1 is along the amplification view of A-A line.
Fig. 4 is that flat steel lateral-bending device shown in Figure 1 is along the amplification view of B-B line.
Fig. 5 is flat steel lateral-bending device locking groove partial enlarged drawing shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing 1~accompanying drawing 5, the utility model is further described.
The utility model provides a kind of band steel bending apparatus, comprise pedestal 1, gathering sill 2, mould 3, spanner 4, axle ear 5, bearing pin 6 and jam plate 7, pedestal 1 can be made by channel-section steel, gathering sill 2 can be comprised of two angle steel, mould 3 can be comprised of two blocks of identical less circular steel plates of diameter of circular steel plate therebetween of diameter, spanner 4 can be by the steel pipe manufacturing of diameter 48mm, gathering sill 2, axle ear 5 is welded to connect with pedestal 1, mould 3 is rotationally connected by bearing pin 6 and axle ear 5, spanner 4 is welded to connect with mould 3, mould 3 has its extended line not by mould 3 centers and runs through the locking groove 8 of mould thickness, the thickness of the width of locking groove 8 and jam plate 7 adapts, mould 3 along the circumferential direction also has the groove 10 that width and band steel to be curved 9 thickness adapt, and the root of groove 10 and locking groove 8 are a bit larger tham the width of band steel 9 to be curved near the vertical range between the limits at mould 3 centers.
In the present embodiment, jam plate 7 is gib head wedge shape, and its thickness of carving the face mid point equates with the width of locking groove 8.
When using this to install crooked band steel, band steel 9 to be curved is put into gathering sill 2 and pass from the groove 10 of mould 3, gib head wedge jam plate 7 is put into locking groove 8, with the gib head position that hand hammer touches gib head wedge jam plate, pin band steel 9 to be curved, pull by hand spanner 4, band steel 9 to be curved is along with mould 3 brake formings, take off wedge jam plate 7, knock molded band steel with hand hammer itself and mould 3 are broken away from, the Flat steel bending process finishes.
Can be by the band steel that angle obtains differently curved angle of pulling of control spanner 4.
Can by adjusting the root diameter (RD) of groove 10, obtain the band steel of differently curved radius.
For the ease of separating of molded band steel and mould 3, should be suitably at lubricating oil such as groove 10 coating butters before bending.
The above only is preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of making within spirit of the present utility model and principle, is equal to and replaces and improvement etc., all should be included within the protection domain of the present utility model.
