Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reach object and effect is easy to understand, following examples are specifically addressed the hydraulic pipe bender being applicable to project installation that the utility model provides by reference to the accompanying drawings.
As depicted in figs. 1 and 2, the hydraulic pipe bender being applicable to project installation that the present embodiment provides comprises: frame 1, hydraulic cylinder 2 and buffer unit 3.Wherein, hydraulic cylinder 2 is connected with the outside pressure source do not shown in figure.
Concrete, frame 1 comprises: two root posts 11 and an entablature 12, and hydraulic cylinder 2 is inverted in the middle part of entablature 12, and the piston rod 21 of hydraulic cylinder 2 runs through entablature 12 and vertically points to ground.The projecting end of piston rod 21 is provided with half circular extrusion head 211, and this structure can effectively prevent the moment that metal tube 10 is contacting with semicircle extrusion head 211 from slippage occurring.For removably connecting between semicircle extrusion head 211 and piston rod 21, and for the metal tube 10 that angle of bend is different, semicircle extrusion head 211 can be that the semicircle extrusion head of a series of different-diameter is formed.
Respectively be provided with a cross slide way 121 in the both sides of piston rod 21 bottom entablature 12, every root post 11 can respectively along corresponding cross slide way 121 transverse shifting.In the present embodiment, cross slide way 121 is the dovetail guide to lower convexity, corresponding, and the top of column 11 offers the dovetail groove matched with this dovetail guide.
As preferred technical scheme, the scale that entablature 12 sidewall is provided with corresponding to cross slide way 121 indicates 122, by this scale indicate 122 can accurate adjustment column 11 relative to the horizontal installation site of entablature 12, thus be convenient to the metal tube 10 of extrusion process different length size or differently curved angle.
For the metal tube 10 of symmetrical bending structure, when adjusting the installation site of column 11, must guarantee that two columns 11 are symmetrical about piston rod 21; For the metal tube 10 of asymmetric bending structure, the installation site of column 11 can be adjusted respectively.
As shown in figures 1 and 3, be fastenedly connected by securing member 4 between the top of entablature 12 and column 11, in the present embodiment, install for the ease of the adjustment of entablature 12 with column 11, entablature 12 respectively offers a waist-shaped hole 123 in the both sides of cross slide way 121, further, waist-shaped hole 123 parallels with cross slide way 121.As preferred technical scheme, securing member 4 is stay bolt, and stay bolt runs through corresponding waist-shaped hole 123 and screws in the upper end of column 11.
As shown in Figure 1 and Figure 4, the middle part of every root post 11 is all provided with a support rail 5, and the projecting end of support rail 5 is provided with deflector roll wheel 6, and metal tube 10 is carried on two deflector roll wheels 6.When piston rod 21 stretches out downwards, the metal tube 10 of straightened condition is extruded gradually and is bent into bending.
Buffer unit 3 is arranged at immediately below piston rod 21, for cushioning the bend of metal tube 10 in extrusion process, the bend of metal tube 10 is made slowly to decline and bend, avoid the too quickly metal tube 10 that causes of piston rod 21 thrust too bending, thus accurately can control the angle of bend of metal tube 10 further.Wherein, buffer unit 3 comprises: have the fixed cover 31 in vertical hole, be placed in spring 32 in vertical hole and bottom is connected with spring 32 and points to the moveable combination of guide rod 33 of piston rod 21.
As preferred technical scheme, the top of moveable combination of guide rod 33 is hinged with two flipping blocks 7, and, two flipping blocks 7 are symmetrical about the center line of moveable combination of guide rod 33, when metal tube 10 is not extruded bending, two flipping blocks 7 are all in level, when metal tube 10 is extruded bending, the crooked position of metal tube 10 to the top bump of moveable combination of guide rod 33, and makes two flipping blocks 7 turn to heeling condition.
What the present embodiment provided is applicable to the hydraulic pipe bender of project installation by installing half circular extrusion head at the projecting end of piston rod, effectively prevent the moment that metal tube is contacting with semicircle extrusion head from slippage occurring, thus ensure that extruding brake forming requires higher bend pipe to symmetrical shape.In addition, two columns can regulate horizontal installation site relative to entablature, thus are convenient to the metal tube of extrusion process different length size or differently curved angle.
Certainly, the hydraulic pipe bender being applicable to project installation involved by the utility model is not merely defined in the structure in the present embodiment, any equivalent modifications of carrying out the utility model and substituting also all in category of the present utility model.
