Description

Hydraulic bending press

The utility model belongs to a kind of press, specifically, is a kind of machine that the linear pattern steel drift is pressed into the camber line shaped steel that has the certain curvature radius that can be used as the mine support material

Mining industry especially colliery uses shaped steel to make support material in a large number, for adding strong supporting strength, the linear pattern steel drift is pressed into the arc steel.Traditional press mainly contains vertical especially big cylinder diameter forcing press, flywheel screw rod impacting type forcing press, the horizontal curved machine etc. that prolongs, defectives such as that ubiquity is bulky, install and use inconvenience, operating noise is big, power consumption is high, big, the required personnel of operator's labour intensity are many, and use mould, a kind of mould can only be pressed a kind of U shaped steel of specification, the mould use amount is big, and it is very inconvenient to change.

At this situation, the utility model proposes the novel bender that a kind of equipment volume is little, low in energy consumption, noise is little, operator's labour intensity is little.

The utility model hydraulic bending press is by girder, be fixed on the bearing structure framework on the girder, the hydraulic power oil cylinder of fixing on the bearing structure framework, be subjected to the linkage of hydraulic power oil cylinder control, the mould dynamic head of guide rod that is connected with linkage and guide rod end and be fixed on the end of girder by the termination fixture, the mould hydrostatic head relative with mould dynamic head position formed, the fluid pressure line of hydraulic power oil cylinder is communicated with hydraulic power unit by operating grip, linkage is made up of pivot link and swing connecting bar, swing connecting bar is connected with pivot link by the connecting rod hinges, one end of pivot link is fixed by fixed hinge, the other end is connected with the telescopic section of hydraulic power oil cylinder by the ball-and-socket jockey, the other end of swing connecting bar passes through connecting rod, the guide rod hinge is connected with guide rod, and girder is provided with the guide rod slideway.

The utility model hydraulic bending press is simple in structure, compact, adopts hydraulic drive, and power consumption and noise are all less, and control is convenient, can realize infinitely variable speeds, and action required personnel are few, and labour intensity is little.

Fig. 1 is the structural representation of the utility model hydraulic bending press embodiment, and Fig. 2 is the structural representation of mould hydrostatic head among the embodiment.

The utility model is described in further detail below in conjunction with drawings and Examples.Bearing structure framework 3 is arranged on the girder 1, during use, shaped steel is placed between mould dynamic head 10 and the mould hydrostatic head 11, by operating grip 12 with hydraulic power unit 16 pressure oil be fed in the epicoele or cavity of resorption of hydraulic power oil cylinder 4 by fluid pressure line 14, make 4 elongations of hydraulic power oil cylinder or retraction, thereby drive pivot link 6 around fixed hinge 2 rotations by connecting ball-and-socket device 17, drive swing connecting bar 7 swings by connecting rod hinges 5, drive guide rod 9 and move along guide rod slideway 15 by connecting rod, guide rod hinge 8 again, extruding shaped steel makes it distortion.What mine support was used in a large number is U shaped steel, in embodiment of the present utility model, aim at the structure that U shaped steel has designed a kind of mould dynamic head 10 and mould hydrostatic head 11: the front panel of mould dynamic head 10 has the arc groove 19 that the arc antiform shape with U shaped steel adapts, mould hydrostatic head 11 is by pedestal 20, two side contact blocks 22 of middle contact block 21 and middle contact block 21 both sides are formed, the front end of middle contact block 21 is equipped with two rollers 23, also respectively be equipped with one on two side contact blocks 22 and sidewinder post 24, roller 23, sidewinder and all have two grooves 25 that can snap in up and down, middle contact block 21 and pedestal 20 bolts on the cylinder of post 24 for the last lower edge of U shaped steel opening.In the course of work, the arc of the U shaped steel back of the body is stuck in the arc groove 19 of mould dynamic head 10, and the last lower edge of its opening is stuck in the groove that sidewinders post 24 25 of two side contact blocks 22.Mould hydrostatic head 11 is fixed on the termination of girder by termination fixture 13, bolt between contact block 21 and the pedestal 20 in the middle of it, can by increase and decrease be connected pad 26 on the bolt regulate in the middle of distance between contact block 21 and the pedestal 20, to adapt to the needs of suppressing different size U shaped steel; When the middle part of U shaped steel is forced into two rollers 23 that prop up middle contact block 21, promptly suppress required U shaped steel specification.This structure is regulated the middle contact block 21 of mould hydrostatic head and the U shaped steel that the spacing between the pedestal 20 can be suppressed different size, does not need more mold exchange.Among the embodiment of the present utility model, also have hinged with pivot link 6 and parallel secondary swing connecting bar 28 and hinged with swing connecting bar 7 and parallel secondary pivot link 27 in the linkage 18 with pivot link 6 with swing connecting bar 7, hinged between secondary swing connecting bar 28 and the secondary pivot link 27, this four-bar linkage structure directly acts on the linkage 18 bearing structure framework 3, its simplification is dwindled, and girder 1 also can not need carry out bending resistance structural strengthening simultaneously.Linkage 18 and bearing structure framework 3 can be horizontally disposed, so that reduce machine gravity, simplified structure.Among the embodiment, mould dynamic head (10) is hinged with the upper surface of guide rod (9), and the purpose of doing like this is, if the compacting of U shaped steel is excessive in operating process, can be with mould dynamic head 10 flip horizontals, and again with U shaped steel flip horizontal, oppositely compacting gets final product.
