Abstract
The utility model discloses a kind of stretch benders, comprise frame and be arranged on above frame for placing the scratch diskette of section bar, the stretch bending oil cylinder that described frame both sides are provided with pivoted arm and drive pivoted arm to rotate, the cylinder ends of described stretch bending oil cylinder is articulated with in frame, the piston rod end of described stretch bending oil cylinder is articulated with on pivoted arm, the upper surface of described pivoted arm is provided with slidably sliding cylinder seat, described sliding cylinder seat is provided with stretching cylinder, the piston rod end of described stretching cylinder is removably provided with section bar clamping device, described section bar clamping device comprises one for clamping the cramping body of section bar and one for preventing the buffer body occurring between cramping body and section bar to rub.By buffer body, cushioning effect is played to section bar during the utility model operation, make section bar two ends leave folding line.
Description
Technical field
The utility model belongs to stretch benders field, is specifically related to a kind of stretch benders.
Background technology
In construction, the shape extrusion such as aluminium section bar, steel will be generally the arc angle shape of transition by the needs due to engineering, to realize the building frame linked up, meets the needs of construction.Stretch benders carry out the capital equipment of stretch bending just for the section bar such as aluminium section bar, steel, section bar is first placed on scratch diskette when stretch bending by existing stretch benders, the two ends of section bar carry out clamping by clamping device to it respectively, then carry out stretch bending operation, namely pull the two ends of section bar to make Bending Deformation.The line bend but go forward side by side in the two ends that clamping device tightly need clamp section bar in the process of stretch bending, very easily leaves folding line, also needs to carry out subsequent treatment to section bar on section bar, by place creasy excision, causes the wasting of resources.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of stretch benders, to overcome the above-mentioned defect of prior art.
The purpose of this utility model is achieved through the following technical solutions:
A kind of stretch benders, comprise frame and be arranged on above frame for placing the scratch diskette of section bar, the stretch bending oil cylinder that described frame both sides are provided with pivoted arm and drive pivoted arm to rotate, the cylinder ends of described stretch bending oil cylinder is articulated with in frame, the piston rod end of described stretch bending oil cylinder is articulated with on pivoted arm, the upper surface of described pivoted arm is provided with slidably sliding cylinder seat, described sliding cylinder seat is provided with stretching cylinder, the piston rod end of described stretching cylinder is removably provided with section bar clamping device, described section bar clamping device comprises one for clamping the cramping body of section bar and one for preventing the buffer body occurring between cramping body and section bar to rub.
Further, described buffer body comprises a loop buffer pad, is also provided with buffer spring between described loop buffer pad and cramping body.
Further, the position near buffer body in described cramping body is set to circular arc.
The beneficial effects of the utility model are: be first placed on scratch diskette by section bar during the utility model stretch bending, the two ends of section bar carry out clamping by section bar clamping device to it respectively, wherein the two ends of cramping body to section bar are fixed, pivoted arm and sliding cylinder seat is driven to move by drive unit, and then buckling work is being carried out to section bar, during operation, buffer body can play cushioning effect to section bar, makes section bar two ends leave folding line.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by description below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of section bar clamping device.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
As shown in the figure, a kind of stretch benders, comprise frame 1 and be arranged on above frame for placing the scratch diskette 2 of section bar, the stretch bending oil cylinder 4 that described frame both sides are provided with pivoted arm 3 and drive pivoted arm to rotate, the cylinder ends of described stretch bending oil cylinder is articulated with in frame, the piston rod end of described stretch bending oil cylinder is articulated with on pivoted arm, the upper surface of described pivoted arm is provided with slidably sliding cylinder seat 5, described sliding cylinder seat is provided with stretching cylinder 6, the piston rod end of described stretching cylinder is removably provided with section bar clamping device 7, described section bar clamping device comprises one for clamping the cramping body 71 of section bar and one for preventing the buffer body 72 occurring between cramping body and section bar to rub.
In the present embodiment, described buffer body comprises a loop buffer pad 721, is also provided with buffer spring 722 between described loop buffer pad 721 and cramping body 71, and in the present embodiment, the position near buffer body in described cramping body is set to circular arc.Because the position near buffer body in cramping body is set to circular arc in the present embodiment, and there is buffer body to play cushioning effect, can not leave a trace on section bar, can the wasting of resources be reduced simultaneously.
In the present embodiment, during stretch bending, first section bar is placed on scratch diskette, the two ends of section bar carry out clamping by section bar clamping device to it respectively, wherein the two ends of cramping body to section bar are fixed, and drive pivoted arm and sliding cylinder seat to move, and then carrying out buckling work to section bar by drive unit, during operation, buffer body can play cushioning effect to section bar, makes section bar two ends leave folding line.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
