Background technology

Bending steel pipe being carried out certain angle is needed in the process of manufacture of chair out of doors, had in the past and relied on mould bending by hand, this kind of method wastes time and energy, the own wt that existing bender has is large, cost is high, and substantially just utilizing mechanics principle to carry out bending, less as raw-material steel pipe caliber in the industry, the tractive force that bending needs is also little, because steel pipe is more crisp, may fracture in Forging Process.

Summary of the invention

For prior art and mechanical problem, the present invention reduces the fragility of steel pipe after utilizing electric heating to soften steel pipe, add steel pipe plasticity, can be better, carry out steel pipe bending process more easily, structure of the present invention comprises operating desk, it is characterized in that: structure also comprises: electric heating bending post, sleeve, the first bending bar, the second bending bar, deck, knuckle locating piece, be all positioned on described operating desk; Described deck can open and be engaged, and handle is arranged at top, and wraps up with heat-barrier material, its occlusal surface is consistent with pipe outer surface to be processed, its one end is flexibly connected described first bending bar, and the other end is flexibly connected described second bending bar, and wherein said first bending bar one end is also fixed with described sleeve; Described electric heating bending post has 2, be individually fixed near described two bending bars and described deck junction, when tubing to be processed be inserted in sleeve blocked by deck time, described two bending bars and described electric heating bending post respectively in the both sides of tubing, and all contact with tubing; Described knuckle locating piece comprises slide rail, two locating dowels, and described locating dowel is stuck in described slide rail, and can be fixed by bolts to any position in slide rail; Described sleeve has inner chamber and locating piece, and described locating piece can prolong its inner chamber and move, and is fixed by bolts to the optional position of inner chamber.

Further, the face that described first bending bar and the second bending bar contact with tubing to be processed is inner concave, described inner concave has high-temperature-resistant layer, two bending bar tubing far away equal activities in end points place are on one side fixed with follower lever, the length of described follower lever equals the length of connected bending bar, the activity of the described follower lever other end is fixed with mechanical push rods, the ejection direction of described mechanical push rods is vertical with the steel pipe to be processed putting into described deck, here, when the design that follower lever is equal with bending pole length can make mechanical push rods ejection drive bending, follower lever drives the running orbit of bending bar just to overlap with tubing bending track, be circular arc, more precisely, the direction of pull of follower lever doubling knee is all the time with perpendicular by bending tubing, principle according to rotating torque is released, its can 100% the tractive force of follower lever is used for bending, so capacity usage ratio is high.

Further, the occlusal surface of described deck has high-temperature-resistant layer.

Further, there is inner concave described electric heating bending post side, and its electric heating temperature controls at 700 DEG C-1000 DEG C.

Further, described locating dowel, locating piece all have the screwed hole of up/down perforation and smooth bottom surface and closed side.

Further, the two ends of the slide rail of described knuckle locating piece respectively with described two electric heating bending posts for the center of circle, bending bar is within the scope of the circular arc of radius.

When the present invention uses, steel pipe to be processed is snapped in deck, sleeve is inserted in its one end, locating piece in regulating sleeve, the bending point of final steel pipe can be regulated, after adjusting locating piece, close upper blocking seat, mechanical push rods is by drive two follower levers, thus drive two the bending bars contacted with steel pipe to be processed to rotate around electric heating bending post, realize bilateral bending process, the temperature of the post of electric heating bending is here arranged on 700 DEG C to 1000 DEG C can make steel soften, its plasticity improves, can be lighter and safe carry out tubing bending, its bending angle can be determined by the locating dowel regulating knuckle to determine block, its whole mechanical realization is simplified, cheap, be applicable to the bending of thinner small-sized steel tubing, can enhance productivity.
