It is an object of the invention to provide the roll-down type apparatus for bending that a kind of structure setting is reasonable and stability in use is good.

The technical scheme for realizing the object of the invention is a kind of roll-down type apparatus for bending, including base, is arranged on the base On support rod, bending cylinder is provided with the support rod, cavity plate is fixed with the end face center of the base, in the folding Bending pressure head is fixed with the piston shaft of curved cylinder, the position of the bending pressure head is engaged with the position of cavity plate, at the bottom Seat on be additionally provided with roll left wedge and right rolling seat, it is described roll left wedge and right rolling seat be symmetricly set on the both sides of cavity plate and be in Between cavity plate and support rod, rolling bar is equipped with roll left wedge and the right rolling seat, passed through in the middle part of the rolling bar Rotary shaft is connected to and rolls left on wedge and right rolling seat, N-shaped roller bearing is provided with the medial extremity of the rolling bar, in the n There is rolling axostylus axostyle in type roller bearing, connected by bearing pin between the piston shaft of the bending cylinder and the outboard end of rolling bar Compress bar, the rolling bar it is described compress bar in the presence of rotated centered on rotary shaft and roll axostylus axostyle from cavity plate to Upper movement is simultaneously pressed on the lateral surface of pressure head.

Strip buffer groove is provided with the N-shaped roller bearing, the strip buffer groove arc block and buffering is being compressed Spring, the buffer spring that compresses is pressed between the outer face of arc block and the side wall of strip buffer groove, the rolling axostylus axostyle Axis rod two ends be in strip buffer groove in and be pressed on the arcwall face of arc block.

It is described roll left wedge and right rolling seat lateral surface be provided with oriented hole, it is described rolling bar outboard end bottom surface Mobile guide bar is fixed with, the bottom of the mobile guide bar is stretched into the oriented hole.

There is back-moving spring between the bottom of the mobile guide bar and the bottom wall in oriented hole.

The width of the rolling axostylus axostyle is stainless steel material solid shaft more than the width and the rolling axostylus axostyle of cavity plate.

The height of the height more than cavity plate of roll left wedge and the right rolling seat.

Its operation principle is summarized as follows, part is placed on cavity plate that start bending cylinder, bending cylinder can drive downwards Bending following is moved down, and realizes positioning part when bending pressure head is pressed on part, and now bending cylinder continues to move down, Bending pressure head continues to move down, and now bending cylinder moves down the outboard end of rolling bar by compressing bar, revolves rolling bar Rotated centered on rotating shaft, and rolling axostylus axostyle is moved up from below cavity plate, power is compressed by roll axostylus axostyle, can be by part Bending is completed with the surface of pressure head upwards.

The present invention has positive effect：Rationally, it first passes through pressure head and realizes determining part structure setting of the invention Position, then proceedes to move down pressure head and while move up rolling axostylus axostyle, it is complete to roll axostylus axostyles by symmetrical two Into the bending of part, the Bending Processing to part is completed, while can also ensure the stress balance at pressure head two ends, such that it is able to significantly Improve the precision of processing, stability in use is good and strong applicability, practicality is good.
