A kind of bender for sheet metal bending
The present invention relates to technical field of mechanical processing, in particular to a kind of bender for sheet metal bending.
In mechanical processing, bending is an important manufacturing procedure.During existing bender use, steel plate warp
After the upper and lower mould bending of bender, since certain elasticity that steel plate has in itself is recovered, it is caused after 90 degree of bendings are carried out,
Commonly greater than 90 degree, and it is difficult to once form required angle, results in the need for being adjusted again, reduce precision and work
The content of the invention
It is an object of the invention to provide a kind of bender for sheet metal bending, to solve the above problems.
To realize the object of the invention, the technical solution that uses for：A kind of bender for sheet metal bending, including rack,
Upper bending part, lower bending part and feed mechanism, lower bending part fixed setting, upper bending part slide up and down setting；Lower bending part
Top is correspondingly provided with holding pad, and holding pad slides up and down setting；The upper bending part includes jacking block and slides pressing plate, above and below jacking block
Slide and set, sliding pressing plate be located at the lower surface of jacking block, and reciprocatingly slides setting along feedstock direction, slides pressing plate and is equipped with slip
Driving device；The side to match with lower bending part of sliding pressing plate is equipped with fillet, slides and is left between pressing plate and lower bending part
Bending gap；The feed mechanism includes drive roll and the driven roller above drive roll, driven roller are connected with
Lifting drive；The either flush of the top surface of driven roller and lower bending part.
Further, rail structure is connected between the side of the jacking block and rack, cylinder is connected with the top of jacking block.
Further, rail structure is connected between the lower surface of the sliding pressing plate and jacking block, slides the remote of pressing plate
The side of lower bending part is connected with cylinder.
Further, rail structure is connected between the side of the holding pad and rack, is connected with the top of holding pad
Further, the sliding driving device is cylinder, and cylinder is fixed on the lower surface of jacking block.
Further, the drive roll is multiple with driven roller, and multiple driven rollers are connected with a stent, institute
It is cylinder to state lifting drive, and the piston rod of cylinder is connected with stent.
The invention has the advantages that by driven roller downlink, drive roll drives and together rotates, and realization is sent automatically
Material, is then moved down by upper bending part, and sliding pressing plate also moves down, and bending, folding are carried out to the material on lower bending part
Sliding pressing plate is moved to material side by sliding the sliding driving device of pressing plate after curved, pressure applied to the material after bending,
So as to compensate for after bending part pushes due to the elasticity of material is recovered and caused by bending defect not in place, by horizontal pressure
Consolidated, ensure that the precision of bending, efficiency is improved, after bending angle reaches requirement, you can sliding pressing plate is retracted, letter
It is single practical, positive effect.
Brief description of the drawings
Fig. 1 is the structure diagram provided by the present invention for the bender of sheet metal bending.
The present invention is described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
Fig. 1 shows the bender provided by the present invention for sheet metal bending, including rack 1, upper bending part 2, lower bending
Part 3 and feed mechanism, lower bending part 3 are fixedly installed, and upper bending part 2 slides up and down setting；The top of lower bending part 3 is correspondingly provided with
Holding pad 4, holding pad 4 slide up and down setting；Upper bending part 2 includes jacking block 21 and sliding pressing plate 22, and jacking block 21, which slides up and down, to be set
Put, sliding pressing plate 22 be located at the lower surface of jacking block 21, and reciprocatingly slides setting along feedstock direction, slides pressing plate 22 and is equipped with slip
Driving device；The side to match with lower bending part 3 of sliding pressing plate 22 is equipped with fillet, makes pushing more smooth, avoids sharp
Corner material is caused to damage, slide and leave bending gap between pressing plate 22 and lower bending part 3；Feed mechanism includes actively rolling
Cylinder 6 and the driven roller 7 above drive roll 6, driven roller 7 are connected with lifting drive；The top surface of driven roller 7
With the either flush of lower bending part 3.
Rail structure 5 is connected between the side of jacking block 21 and rack 1, the top of jacking block 21 is connected with cylinder, so exists
During sliding up and down, the top of jacking block 21 is drive end, and side is slide-and-guide side, it is steadily moved relative to rack 1.
Rail structure 5 is connected between sliding pressing plate 22 and the lower surface of jacking block 21, sliding is more stablized, and slides pressing plate 22
The side of remote lower bending part 3 be connected with cylinder.Rail structure 5, binder are connected between the side of holding pad 4 and rack 1
The top of plate 4 is connected with cylinder.Sliding driving device is cylinder, and cylinder is fixed on the lower surface of jacking block 21.
Drive roll 6 is multiple with driven roller 7, and multiple driven rollers 7 are connected with a stent, lifting drive
For cylinder, the piston rod of cylinder is connected with stent, so as to drive the lifting of driven roller 7, drive roll 6 is connected with driving electricity
As shown in Figure 1, steel plate material 8 after between drive roll 6 and driven roller 7, entering on lower bending part 3, is pressed
Flitch 4 pushes, and fixes material, and upper bending part 3 pushes, and makes material bending, and driving sliding pressing plate 22 is moved to material side, is depressed into
The side of material, makes bending reach requirement.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
