Description
Technical field
The utility model relates to a kind of steel construction processing unit (plant), relates in particular to a kind of square-section steel member bending device.
Background technology
Structure steel fabrication manufacture field, for the bent member that needs circular arc profile, generally adopts two kinds of methods at present, and the one, member is carried out to simmering and bending, adopt mode of heating, member temperature is elevated to higher temperature, then carries out stretch bending or press-bending, reach design radian.The method is mainly applicable to the less member in cross section, and temperature required being difficult to of larger member reaches; The 2nd, member is respectively formed to steel plate and bend respectively, then assembly welding becomes entirety, and the method is mainly applicable to square-section and larger member, its each composition face steel plate is large (thick), press-bending is had relatively high expectations, and because each plate distortion is difficult to accurate control, while therefore assembling, can have larger error.
Utility model content
For above shortcomings in prior art, the utility model provides a kind of square-section steel member bending device that can accurately control.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of square-section steel member bending device, comprises a rack platform, a jacking bracket, a bending seat and three limit bases; Described jacking bracket is fixed on rack platform, three limit bases are arranged on rack platform and are distributed on a camber line, and described bending seat is arranged between jacking bracket and middle limit base and is slidably matched with rack platform in the direction of jacking bracket and middle limit base line; Realizing middle limiting seat is slidably coordinating with rack platform with in the direction of jacking bracket line, and three limit bases arrange the arcwall face of indent towards the one side of jacking bracket, and described bending seat arranges the arcwall face of evagination towards the one side of middle limit base.
As a kind of preferred version of the present utility model, this square-section steel member bending device also comprises jack, and jack is placed between jacking bracket and bending seat, and the base of jack withstands on jacking bracket, and the piston top of jack is at bending seat.
As another kind of preferred version of the present utility model, square-section steel member bending device also comprises the limited block that is provided with evagination arcwall face; A limited block is arranged on the inner side of a side limit base, and another limited block is arranged on the inner side of opposite side limit base, and the evagination arcwall face of limited block is slidably matched with the arcwall face of the indent of corresponding limit base.
Compared with prior art, the utlity model has following advantage:
1, process velocity is fast; Because this device is directly member integrated to be processed, the process that does not exist member to re-assembly, therefore process velocity is than very fast.
2, machining accuracy is higher, and with carrying out Measurement accuracy to member bending deformation in sample device process, therefore member machining accuracy is higher.
Brief description of the drawings
Fig. 1 is the structural representation of square-section steel member bending device.
In accompanying drawing: 1-rack platform; 2-jacking bracket; 3-bending seat; 4-limit base; 5-jack; 6-limited block.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of square-section steel member bending device, comprises that a rack platform 1, jacking bracket 2, bending seat 3, three limit bases 4, jack 5 and two are provided with the limited block 6 of evagination arcwall face.Jacking bracket 2 is fixed on rack platform 1, three limit bases 4 are arranged on rack platform 1 and are distributed on a camber line, and bending seat 3 is arranged between jacking bracket 2 and middle limit base 4 and is slidably matched with rack platform 1 in the direction of jacking bracket 2 and middle limit base 4 lines.Realizing middle limiting seat 4 is slidably coordinating with rack platform 1 with in the direction of jacking bracket 2 lines, and three limit bases 4 arrange the arcwall face of indent towards the one side of jacking bracket 2, and bending seat 3 arranges the arcwall face of evagination towards the one side of middle limit base 4.Jack 5 is placed between jacking bracket 2 and bending seat 3, and the base of jack 5 withstands on jacking bracket 2, and the piston top of jack 5 is at bending seat 3.
One of them limited block 6 is arranged on the inner side of a side limit base 4, and another limited block 6 is arranged on the inner side of opposite side limit base 4, and the evagination arcwall face of limited block 6 is slidably matched with the arcwall face of the indent of corresponding limit base 4.This limited block 6 is when stressed, can on corresponding limit base 4, regulate by the slip between evagination arcwall face and the arcwall face of indent, make square-section steel member to be bent form good contacting with limited block 6 in BENDING PROCESS, and then after making square-section steel member brake forming to be bent, profile is more approximately circular arc.
While using this square-section steel member bending device, first square-section steel member to be bent is placed between bending seat 3 and three limit bases 4, utilize jack 5 as power source, the piston of jack 5 promotes bending seat 3 and is pressed on square-section steel member to be bent, square-section steel member to be bent is bent gradually under the acting in conjunction of two limited blocks 6 of bending seat 3 and both sides, until bent into shape.If square-section steel member to be bent is longer, sectional carries out bending.According to designing requirement radian, calculate the stroke that this place square-section steel member to be bent needs jacking.Then according to calculating gained stroke, square-section steel member to be bent is surpassed to top.Because what square-section steel member bending to be bent entered is elastic-plastic phase, it is not the bending plastic stage, some is to want resilience for distortion now, therefore will surpass top to square-section steel member to be bent, to ensure that member final molding meets design requirement.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
