Description

Profile bender

The utility model relates to a kind of machinery of bent section.

In the prior art, be used for the machinery of crooked pipe many with the roll extrusion of plural pair of rollers pipe so that tube bending, but bending machine of the prior art is in order to regulate the crooked radian of pipe, the normal way of the mould of changing roller that adopts realizes, it is very time-consuming to operate, and the working site needs a lot of moulds, has increased production cost.

The purpose of this utility model is to provide a kind of profile bender of radian of the conveniently adjusted section bar that is bent.

The technical solution of the utility model is: it comprises support, first initiatively guide wheel shaft, the second active guide wheel shaft, driven guide wheel shaft; The described first active guide wheel shaft, the second active guide wheel shaft, driven guide wheel shaft lay respectively at three summits of isosceles triangle, the described first active guide wheel shaft is provided with the first active guide wheel, the described second active guide wheel shaft is provided with the second active guide wheel, and described driven guide wheel shaft is provided with driven guide wheel; The described first active guide wheel shaft and second initiatively guide wheel shaft connects with actuating unit, and described driven guide wheel shaft is connected with support by lowering or hoisting gear.Described driven guide wheel shaft with first initiatively guide wheel shaft, second initiatively guide wheel shaft parallel, described driven guide wheel shaft is positioned at first guide wheel shaft, second initiatively on the perpendicular bisector of the line of guide wheel shaft initiatively.

The utility model compared with prior art has following advantage:

Section bar is looked driven between the guide wheel from the first active guide wheel and is entered, come out between the second active guide wheel and driven guide wheel, owing to driven guide wheel is pressed on the section bar, and driven guide wheel is because the residing position of lifting difference, can impose different pressure to section bar, thereby regulate the radian that is bent of section bar.The bigger section bar of camber ratio can first little bending curvature, regulates the section bar that can bend to big radian behind the position of return idler again.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural front view of the present utility model, and actuating unit is wherein partly cut open;

Accompanying drawing 2 is a vertical view of the present utility model, and double dot dash line is illustrated on the corresponding axle guide wheel is housed, and the junction part of the second active guide wheel shaft and support is cut open among the figure; Wherein:
