Detailed description of the invention
Elaborate below in conjunction with the detailed description of the invention of accompanying drawing to a kind of bender of the utility model.
See accompanying drawing 1,2, bender 100 comprises upper table 1 and lower table 2, and upper table 1 and hydraulic press assemble, and arranges upper padding plate 3, patrix cutter 4, holding pad 5, counterdie overturn pressing plate 6, height limiting plate 7 and lower bolster 8 between upper table 1 and lower table 2.
The front side of bender 100 is for entering plate side, and rear side is bending side, and the direction of transfer of sheet material 9 transmits from entering plate side level to bending side.
Between patrix cutter 4 and upper padding plate 3, upper link stopper 24 is set according to hydraulic press stroke, and is connected by guide pad 23.
Holding pad 5 and counterdie upset pressing plate 6 are connected with lower bolster 8 by guide elements 20 with height limiting plate 7, can realize upper and lower displacement relative to guide elements 20.Entering below the holding pad 5 of plate side to arrange sheet material alignment pin 10, arrange spring 11 below sheet material alignment pin 10, holding pad 5 end face entering plate side arranges hold-down screw 12, and sheet material alignment pin 10 is fixed on a correct position by hold-down screw 12.
The patrix cutter 4 of bending side arranges a patrix cutter head 13, patrix cutter head 13 end face vertical with the holding pad 5 of bending side, patrix cutter head 13 is sphenoid bur, the bending side end face of counterdie upset pressing plate 6 and holding pad 5 vertically end face, form an angular space within the bending side end face of the bending side end face indentation counterdie upset pressing plate 6 of height limiting plate 7.
Arrange in the below of the counterdie upset pressing plate 6 entering plate side and flatten block 14, what flatten that block 14 is positioned at height limiting plate 7 enters side, plate side, flatten the bottom surface of bottom surface higher than height limiting plate 7 of block 14, both differences in height are the thickness of two sheet materials 9, when patrix cutter 4 presses down by hydraulic press, when height limiting plate 7 and lower bolster 8 pressing, sheet material 9 doubling pre-bended flattens by the gap flattened between block 14 and lower bolster 8.Lower bolster arranges bent plate alignment pin 15 near entering plate side, and bent plate alignment pin 15 is positioned at the below flattening block 14, and the sheet material 9 that pre-bends that will be folded in half located by bent plate alignment pin 15.
Lower bolster 8 arranges a lower die cutter 17 by a mould cutter holder 16, and the top of lower die cutter 17 is counterdie cutter head 18, mould cutter holder 16 is arranged a rotating shaft 19, and rotating shaft 19 is perpendicular to the direction of transfer of sheet material 9, and lower die cutter 17 is arranged in rotating shaft 19.
Lower die cutter 17 is offering groove 21 towards the side of the vertical end face of holding pad 5, the upper surface of groove 21 is inclined upwardly and forms the lower die cutter brilliance with the vertical plane of groove 21, the key groove of patrix cutter head 13 is equal with the lower die cutter brilliance, groove 21 lower surface is level, and the lower surface of groove 21 is positioned at the below of angular space counterdie upset pressing plate 6.
Arrange backstop rule 22 in bending side, backstop rule 22 will limit sheet material 9 by the length of bending part.Backstop rule 22 are realized the setting of position length by numerical control unit.
When hydraulic press is at initial position, the upper surface of holding pad 5 exceeds the top of counterdie cutter head 18, and counterdie cutter head 18 and holding pad 5 vertically end face coordinate, and lower die cutter 17, due to 19 rotations around the shaft, to make between its bottom surface and lower bolster 8 shape in an angle.
When hydraulic press presses down, sheet material 9 is pressed in after between patrix cutter 4 and holding pad 5, holding pad 5 is moved down by guide elements 20, lower die cutter 17 is along the vertical end of holding pad 5 to relatively moving up, when lower die cutter 17 around the shaft 19 turn to groove 21 be placed on patrix cutter head 13 upper surface and counterdie overturn the lower surface of pressing plate 6 time, the bottom surface of lower die cutter 17 coordinates with lower bolster 8.
When hydraulic press promotes, due to the effect of guide elements 20, holding pad 5, counterdie upset pressing plate 6 and height limiting plate 7 rise to initial position, and at this moment, counterdie cutter head 18 19 rotates and falls on the vertical end face of holding pad 5 from the lozenges of patrix cutter 4 around the shaft.
See accompanying drawing 3, below by the process of carrying out folding 90 degree curved to sheet material 9, bender 100 is described, the width of bending is wanted to set the position of backstop rule 22 according to sheet material 9, by sheet material 9 from entering holding pad 5 that plate thruster enters below patrix cutter 4, until the location of backstop rule 22.
Start hydraulic press, after hydraulic press presses down, patrix cutter 4 times general who has surrendered's sheet materials 9 are pressed between patrix cutter 4 and holding pad 5, after holding pad 5 is subject to downforce, to bottom offset under the effect of guide elements 20, at this moment, lower die cutter 17 moves up relative to holding pad 5, and the cutter head of lower die cutter 17 shifts to sheet material 9, sheet material 9 is subject to the cutter head thrust of lower die cutter 17 with the cutter head position of patrix cutter 4, sheet material 9 upwards bending, after setting hydraulic press stroke, makes sheet material 9 bending to 90 spend.Hydraulic press press down the bending angle that stroke determines sheet material 9.Want the angle that bending is different, the stroke that presses down of hydraulic press can be regulated to realize.
Hydraulic press promotes, and holding pad 5, counterdie upset pressing plate 6 and height limiting plate 7 go up to initial position, and lower die cutter 17 declines relatively, and the cutter head of lower die cutter 17 leaves sheet material 9.Hydraulic press continues to promote, and patrix cutter 4 leaves sheet material 9, and operating personnel have extracted the sheet material 9 of bending out bending work from bender 100.
See accompanying drawing 4, flatten technique be described below by carrying out flanging to sheet material 9, previous action is the same with sheet material 9 Forging Process.After sheet material 9 bending, hydraulic press continues to press down, groove 21 lower end of lower die cutter 17 is subject to the downforce of the lower end of counterdie upset pressing plate 6, lower die cutter 17 19 is rotated counterclockwise around the shaft, and the cutter head of lower die cutter 17 is out of shape the bending that sheet material 9 produces to the lozenges of patrix cutter 4, when the bottom surface of lower die cutter 17 and lower bolster 8 are fitted between this, bending terminates, hydraulic press promotes, and lower die cutter 17 resets, and Forging Process completes.
The bending end of the sheet material 9 after bending is put on the lower bolster 8 below pressing block 14 by operating personnel, and located by bent plate alignment pin 15, hydraulic press presses down, and is flattened by bending part.
See accompanying drawing 5, above-described flanging flattens technique, in the process of bending, and can by flattening operation to the sheet material of pre-flanging on the holding pad entering plate side position of sheet material alignment pin.Concrete operations are, the process that pre-bends, with above mentioned the same, after pre-bending, patrix cutter lifted and is departed from holding pad, sheet material alignment pin is due to the effect of spring, stretch out from holding pad, the bending end of the sheet material 9 after bending is put between patrix cutter and holding pad by operating personnel, is located by the sheet material alignment pin stretched out, hydraulic press presses down, sheet material between patrix cutter and holding pad is flattened, after sheet material alignment pin is subject to the pressure of patrix cutter, spring contraction.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
