The specific embodiment
As shown in Figure 1, the numerical control hoop bender of present embodiment is made up of numerical control device 500 and rack-mounted steel bar stretching device 100, alignment pay-off 200, shear 300, bending apparatus 400; Numerical control device 500 is connected with stretching device 100, alignment pay-off 200, shear 300, bending apparatus 400 respectively and it is controlled.
As shown in Figure 2, when the numerical control hoop bender of present embodiment is worked, reinforcing bar 1 is stretched by stretching wheel 4 tractions by stretching die 3 backs and advances, stretching wheel 4 drives after being slowed down by reductor 8 by motor 2, reinforcing bar 1 is stretched under the acting in conjunction of stretching die 3 and stretching wheel 4, and the reinforcing bar 1 after the stretching enters between niproll 9 and the following niproll 10 and clamped by elasticity.Two niprolls are contained in respectively on the door-shaped frame 18 by axle 14,15 and bearing 16,17.Between axle 15 and the doorframe 18, connect by a pair of helical compression spring 27, minor sprocket 11 is equipped with in the outer end of axle 14.The gap can elasticity change to adapt to the needs of different-diameter reinforcing bar between two rollers.
Niproll is to be driven by the minor sprocket 11 that is contained in hinge wheel 13 and the chain 12 on the stretching wheel 4 and be contained on the axle 14, and its linear velocity and stretching wheel are synchronous.Reinforcing bar 1 needs synchronous with stretching wheel by niproll and niproll, its objective is reinforcing bar 1 is tightened, and can closely be wrapped on the stretching wheel 4 unlikely loosening skidding during stretching.
As shown in Figure 2, reinforcing bar 1 promptly enters after niproll comes out in the guiding mould 19, between guiding mould 19 and the niproll 10～15 meters spacing is arranged.This is in order to make the reinforcing bar 1 for the treatment of bending can be sagging between guiding mould 19 and niproll, to keep certain nargin, storage is arranged, can regulating supply and demand.
As shown in Figure 3, reinforcing bar 1 enters horizontal coalignment 20 and charging wheel 21 successively after mould 19 comes out from leading, this charging wheel 21 is driven by series of gears 23 by servomotor 22, and reinforcing bar 1 is carried out the horizontal direction alignment, enters vertical coalignment 24 then and carries out the vertical direction alignment.Through after the both direction alignment, reinforcing bar 1 enters between the blade of shear 300, and then enters between the pin bent 27 and central shaft 28 above the bend wheel 29 of bending apparatus 400.After the instruction of receiving numerical control device 500, under the drive of servomotor 30, bend wheel 29 is done certain angle according to instruction and is rotated, and gets back to original position after reinforcing bar 1 is curved respective angles.After servomotor 22 is received the command adapted thereto of numerical control device 500, drive charging wheel 21 and make reinforcing bar 2 by the instruction of the numerical control device certain-length that advances, bend wheel 29 carries out bending again according to instruction then, carries out so successively.After having bent each required limit of stirrup, angle, shear 300 will be received the instruction of numerical control device 500, and cutting blade is moved to ledger-plate, cuts off reinforcing bar.So just obtained meeting the complete stirrup of command request, hoop bender is just finished a working cycles.
The work of numerical control hoop bender stretching device 100 is successional, and the charging of its bending apparatus 400 interruption is carried out, and charging stops when crooked and cut-out reinforcing bar.For making both synchronous coordination operations, as shown in Figure 2, between the guiding mould 19 of alignment pay-off 200 and stretching device 100,10～15 meters spacing is set, make the reinforcing bar 1 that stretches before entering bending apparatus 400, between alignment pay-off 200 and stretching device 100, remain certain sag, make the reinforcing bar for the treatment of bending that certain nargin be arranged, storage is arranged, can regulate supply and demand.
Fig. 4 is the arrangement mode schematic diagram of two stretching dies.As shown in Figure 4, numerical control hoop bender of the present utility model can be provided with two stretching dies 3, simultaneously two reinforcing bars is stretched.Fig. 5 is the structural representation of guiding mould, and as seen from Figure 5, guiding mould 19 can be that two reinforcing bars lead simultaneously.Numerical control hoop bender of the present utility model can carry out bending hoop processing to two reinforcing bars simultaneously, and its operating process is consistent with above-mentioned flow process.
Above-mentioned a series of actions of numerical control hoop bender is to be controlled respectively in each device by numerical control device 500 to realize by instruction operation as each motor of power, makes entire machine be able to a series of instruction synchronous coordination work of being sent according to numerical control device 500.
