The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
embodiment 1.
As shown in Figures 1 to 4, a kind of stretch benders of the present utility model, comprise the scratch diskette 2 that install frame 1 and frame 1 top, the stretch bending oil cylinder 4 that frame 1 both sides are all articulated with pivoted arm 3 and drive pivoted arm 3 to rotate, the cylinder ends of described stretch bending oil cylinder 4 is articulated with frame 1, the piston rod end of stretch bending oil cylinder 4 is articulated with pivoted arm 3, the top end face of described pivoted arm 3 is provided with slidably sliding cylinder seat 5, described sliding cylinder seat 5 is provided with stretching cylinder 6 that can oscilaltion, and the piston rod end of described stretching cylinder 6 is removably provided with clamping device 7.
During work, section bar is laterally placed on the scratch diskette 2 of installing frame 1 top, the two ends of section bar are carried out clamping by clamping device 7 to it respectively, then stretch bending oil cylinder 4 carries out work, the piston rod of stretch bending oil cylinder 4 pulls the hinged pivoted arm 3 in frame 1 both sides to rotate centered by hinged place, because the top end face of pivoted arm 3 is provided with sliding cylinder seat 5, and stretching cylinder 6 is installed on again on sliding cylinder seat 5, simultaneously, clamping device 7 is installed on the end of the piston rod of stretching cylinder 6, make stretch bending oil cylinder 4 pull the two ends of section bar to do flexural deformation, in the technical program, frame 1, between pivoted arm 3 and stretch bending oil cylinder 4, it is bolt cam relation, stretching cylinder 6 can rise or decline with respect to sliding cylinder seat 5, in actual mechanical process, regulate as required stretching cylinder 6 to rise or decline, and rotate or change clamping device 7 to meet the different section bar of clamping or section bar to be carried out to the stretch bending work of different directions, for example, when needs are that rectangular aluminium section bar carries out stretch bending when work to cross section, according to the concrete situation about using of construction, need to carry out stretch bending (two faces rectangular " length " and " wide " carry out stretch bending) to two of aluminium section bar different cross sections, in the situation that traditional stretch benders fixedly stretching cylinder 6 and clamping device 7, cannot meet both of these case is carried out to stretch bending simultaneously, but the technical program only need to upwards rise stretching cylinder 6 by regulating, make clamping device 7 rotate 90 ° simultaneously, can realize cross section is that rectangular aluminium section bar carries out the not stretch bending work of ipsilateral, meet section bar is carried out to the stretch bending work of different directions, and when aluminium section bar is circular cross-section, the technical program also only need to unload existing square clamping device 7, replace with circular clamping device 7 and can meet the aluminium section bar of circular cross-section is carried out to stretch bending.The utility model as required adjustable stretching cylinder 6 rises or declines, thereby realizing the clamping device 7 that the piston rod end of stretching cylinder 6 is installed rotates or changes, thereby meet the stretch bending that the section bar of different size model is carried out to different directions, simple to operate, production efficiency is high, applied widely, practical.
In the present embodiment, described stretching cylinder 6 is fixedly connected with screw rod 8, described screw rod 8 is also connected with sliding cylinder seat 5 by nut 9 through the top of described sliding cylinder seat 5, by unscrewing nut 9, then screw rod 8 is risen or step-down operation, fastening nut 9 again after complete, whole operating process is quite simple, and it is very reasonable to design.
Because intensity and the rigid phase of aluminium section bar itself are worked as large, in the aluminium section bar process of stretch bending circular cross-section, for preventing that the aluminium section bar of circular cross-section from rotating, affect stretch bending effect, the technical program is directly at hinged first fagging 10 of cylinder body of stretching cylinder 6, hinged the second fagging 11 on clamping device 7, the first fagging 10 and the second fagging 11 are hinged, in stretch bending process, stretching cylinder 6 maintains static moving, stretching cylinder 6 is hinged with clamping device 7 by the first fagging 10 and the second fagging 11 that are hinged, defining clamping device 7 can not rotate, that is to say the phenomenon that can prevent from occurring when clamping device 7 from clamping aluminium section bar stretch bending rotation, the normal stretch bending work that keeps stretch benders, increase work efficiency.
In the present embodiment, described pivoted arm 3 is provided with drive unit, and described drive unit is connected with sliding cylinder seat 5, and sliding cylinder seat 5 reciprocatingly slides in pivoted arm 3 under the drive of drive unit.Drive unit can drive sliding cylinder seat 5 to realize and slidably reciprocating at the top end face of pivoted arm 3, so that the position of the clamping device 7 that the piston rod end of adjusting stretching cylinder 6 connects, thereby can meet the clamping requirement to the aluminium section bar of different length, 6 of stretching cylinders can carry out elongation work to aluminium section bar.
Concrete, the front side of described pivoted arm 3 forms flange 31, and the rear side of pivoted arm 3 forms hollow bulb 32, and the piston rod of described stretch bending oil cylinder 4 is hinged with the flange 31 of pivoted arm 3 through the hollow bulb 32 of described pivoted arm 3.Stretch benders are in the process of stretch bending aluminium section bar work; the piston rod of stretch bending oil cylinder 4 carries out in the hollow bulb 32 of pivoted arm 3; guarantee the compactedness of whole equipment work; simultaneously; the hollow bulb 32 of pivoted arm 3 can also play a protective effect to the piston rod of stretch bending oil cylinder 4, prevents that the external force of extraneous thing or generation from damaging the piston rod of stretch bending oil cylinder 4.
More specifically, described scratch diskette 2 is provided with stretch bending mold, and stretch bending difformity aluminium section bar can be installed different stretch bending molds on scratch diskette 2 as required, to meet, the aluminium section bar without shape is carried out to stretch bending, uses flexibility strong.
In the present embodiment, described stretching cylinder 6 is installed on the center of described sliding cylinder seat 5, and install stretching cylinder 6 centers, can meet the stretch bending that aluminium section bar is carried out to relatively large radius.
embodiment 2.
As shown in Figure 5, the present embodiment is with respect to the difference of embodiment 1, described stretching cylinder 6 is installed on the eccentric position of described sliding cylinder seat 5, stretching cylinder 6 eccentric positions are installed, can to some aluminium section bars, carry out specially the stretch bending of small radii, use has more specific aim, is also a kind of mapping mode of embodiment 1.
The remainder of the present embodiment is identical with embodiment 1, repeats no more here.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
