Stirrup bender

Technical field

The utility model has related to a kind of reinforcing bar process equipment, particularly a kind of stirrup bender.

Background technology

Along with the development of scientific and technological level and the raising of human lives's quality, reinforced concrete structure has become the building structure of the most important and widespread usage of current building field, in structure of reinforced concrete, usually need in girder construction and rod structure, use stirrup, stirrup can satisfy the oblique section shearing strength on the one hand, and connect stressed main muscle and the compressive region concrete makes its co-operation, be to be used for fixing the position of main reinforcement and to make that various reinforcing bars constitute frameworks of steel reinforcement in the member (beam or post) on the other hand, stirrup equally is absolutely necessary with main muscle, but stirrup is different from main muscle, main muscle is general only need to get final product according to the length setting of structure, and stirrup needs to process according to the cross sectional shape of structure, the stirrup of the structure of general circular cross-section can directly be wound on the main muscle outside, and stirrup fixedlyed connected with main muscle, and to be the stirrup that uses in the reinforced concrete structure of rectangle need shift to an earlier date blanking in cross section commonly used and bend, and rectangle hoop generally comprises two kinds of bending angles, comprise two 135 ° of bendings of three the 90 ° of bendings and ends in middle part, during present construction is produced, stirrup mostly adopts manually and bends, the stirrup precision that is bent into is low on the one hand, it is low to bend efficient, influence the installation of stirrup and the construction quality of reinforced concrete structure, on the other hand, manually bend producers' labour intensity height in the process.

The utility model content

The utility model provides a kind of can effectively improve stirrup production efficiency, guarantees the stirrup bender of stirrup quality.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: stirrup bender, and its key improvements is: the identical angle bender structure of structure that comprises frame, is located at the operating platform of frame top, drive motors and the decelerator of being located at frame base cross members middle part and is symmetrically set in the decelerator both sides; Described angle bender structure comprise the tooth bar support be located on the frame base cross members, by the slide rail level be located at tooth bar on the tooth bar support, with the tooth bar meshed gears and be located at driving wheel on the operating platform; Tooth bar is hinged with the eccentric wheel that is installed on the reducer output shaft by pull bar, fix by the bearing block that is installed on the vertical bar of frame with the power transmission shaft that gear is affixed, the driving wheel that is installed in the power transmission shaft top passes the diameter that is provided with on the operating platform circular hole greater than driving wheel, the driving wheel end face parallels with operating platform, and the driving wheel end face is provided with fixedly limited post and the eccentric limited post that axis and drive shaft axis coincide; Also comprise the limited block that is positioned at driving wheel one side that is fixed at the operating platform top.

Adopt the beneficial effect that technique scheme produced to be: two limited posts are set on the driving wheel that is parallel to the operating platform end face, and the limited block be positioned at driving wheel one side is set on the operating platform end face, because driving wheel is driven by rack-and-pinion, after the effect of rack-and-pinion is to convert gyration to straight reciprocating motion, again straight reciprocating motion is converted to the reciprocating rotating motion of driving wheel, so when driving wheel rotates, have only the relative operating platform circulation of eccentric limited post to produce angular displacement, and limited block and fixedly limited post do not produce relative displacement, thereby can insert eccentric limited post, the fixedly reinforcing bar bending between limited post and the limited block; The utility model is also by being provided with the stroke adjustment plate between pull bar and tooth bar connecting plate, regulate the reciprocal anglec of rotation of driving wheel by the stroke of regulating tooth bar, thereby realize that same set of driving wheel can realize the bending of two kinds of angles, and do not disturb mutually between the symmetrically arranged two cover angle bender structures, can effectively enhance productivity, reduce producers' labour intensity.
