Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further details:
Would generally use a lot of connecting plate in steel tower construction, these connecting plates typically have certain angle, and owing to ensure its intensity, the method all using fire bent makes.Fire bent point two kinds, a kind of is that artificial fire is bent, the slowest, and end product quality extreme difference, production requirement can not be met far away, it is only applicable to use temporarily, a kind of bent machining of employing fire, fire bent machinery a great variety, but operation principle is the most consistent, all configuration firing equipment and press bending apparatus, bending apparatus typically all hydraulic drive mechanism drives bending mould to be curved, this bending mould includes mold and lower mold, strip pressing plate is wherein set on mold, strip groove is set in lower mold, the strip pressing plate of mold is corresponding with the strip groove in lower mold, strip pressing plate and strip groove are upper, the groundwork position of lower mold.During bent plate, only need to be placed between mold and lower mold by sheet material, mold is descending under hydraulic drive mechanism drives, and makes sheet material bending and forming.
The present invention is secondary development based on the bent machine die of existing fire, including mold and lower mold, wherein arranges strip groove in lower mold, and strip groove is corresponding with the strip pressing plate of mold, and the width of strip groove is more than the width of strip pressing plate.As shown in Figure 1, mold of the present invention includes connecting plate 1, strip pressing plate 3 and reinforcing plate 2, reinforcing plate has three pieces, middle vertical welding one piece of reinforcing plate fixes strip pressing plate 3, other two block weldings are fixed on the side of strip pressing plate 3, and three pieces of reinforcing plates constitute prismatic, and connecting plate 1 is fixed on the centre position of the reinforcing plate vertical with strip pressing plate 3, and it is positioned at another side (one side relative with strip pressing plate 3), for connecting the drive rod of hydraulic drive mechanism.On described strip pressing plate 3, draw-in groove 4 is set, draw-in groove 4 vertical with strip pressing plate 3 and with and the vertical reinforcing plate of strip pressing plate 3 vertical, it is and offers by the upwardly extending draw-in groove in bottom surface 4 along short transverse, placed angle model 5 in draw-in groove, angular templet 5 is one block of sheet material, its surface is the shape that two symmetrical right-angled trapezium are formed with the right-angle side split that two right-angle sides are the longest, sees Fig. 2.Angle between two hypotenuses of two corresponding right-angled trapezium is model angle side.Angular templet 5 thickness and card well width match, and (card well width and angular templet are of uniform thickness or bigger, i.e. use matched in clearance), angular templet 5 height is more than or equal to card groove depth, after angular templet puts in, its model angle side is positioned at outside, for propping up the sheet material needing bending, provide model for the bent angle of fire.
The balance of whole device (mold) during in order to ensure hydraulic-driven, the present invention optimizes draw-in groove position further, and draw-in groove 4 is opened in the middle of strip pressing plate 3.
In order to ensure bent being smoothed out of fire, not damaging angular templet, during fire song, model is indeformable, does not damages, and described angular templet 5 thickness should be greater than equal to 2 millimeters.
In order to ensure the normal use of mould, according to practical situation and the type of work piece, being defined the thickness of the strip pressing plate of the mold of design, the thickness of strip pressing plate should be greater than 1.5 times or more than 1.5 times of workpiece thickness, generally workpiece thickness.
Operation principle:
nullDuring fire bent plate material，Processed sheet material is placed on the top of lower mold，Angular templet is placed on processed sheet material location and carries out the position that fire is bent，Model angle side and web contact，Angular templet is vertically placed and corresponding with the strip pressing plate of mold，Carrying out with the song that catches fire，Processed sheet material angle moves closer to angle to be processed，When processed sheet material contacts with two hypotenuses of angular templet it is，Angular templet is also sticked into draw-in groove，The bent angle of fire of fire bent plate material is consistent with fire song model，If now fire is bent further，Hydraulic-driven power can be dispersed on angular templet，Be equivalent to reduce the driving force that fire is bent，Fire bent plate material angle no longer changes，The bent process of whole fire completes，The bent plank stuff one-shot forming of fire，And the sheet material angle agreement of fire song is the best，This invention not only alleviates the labor intensity of workman，But also the speed making fire bent improves nearly 5 times，Processing cost significantly reduces，Improve income.
