Currently marketed vertical bending machine cabinet sweep many employings belt transmission.As in existing technical literature, notification number is CN2018808286U, the vertical type steel-bar bending machine of compound bending by name, and what utilize said structure to complete reinforcing bar exactly is bending.
But there is following shortcoming in above-mentioned technology: 1. make dial rotation power source in transmittance process, the kind of drive of employing is V belt translation, and band rotate under high pressure easily skid; 2. the belt Long-Time Service of V belt translation, easily fluff, and bending machine structure is compact, is difficult to reach to the tensioning of belt; 3. reinforcing bar is due to the physical property of self, although so can distortion be produced according to bending machine in BENDING PROCESS to its externally applied forces, after removing and executing external force, still can there is the phenomenon of resilience in reinforcing bar, and the angle of bend of reinforcing bar after resilience can exist error with the angle of bend of expection.
Summary of the invention
The purpose of this utility model is exactly the coarse problem of angle of bend in order to solve bending machine of the prior art, provides a kind of bending apparatus preventing the vertical bending machine removing force effect reinforcing bar resilience later.
Concrete scheme of the present utility model is:
Design a kind of bending apparatus of vertical bending machine, described bending apparatus comprises the central shaft that the gear transmission unit connecting power source, the rotating disk coordinated with this gear transmission unit output shaft, rotating disk are arranged and the eccentric shaft arranged through rotating disk card.
Described rotating disk card is provided with through hole, and described eccentric shaft is in described through hole, and is connected with the driver part making it move axially along through hole.
Described gear transmission unit comprises incomplete gear mechanism.
Described bending apparatus also comprises oil groove, and this oil groove correspondence is in the below of described partial gear.
Described driver part is liquid/gas cylinder pressure.
Rotating disk is provided with limit switch, and this limit switch and described power source form current control loop, control the keying of described power source.
The central shaft of described bending apparatus comprises two fixture blocks be oppositely arranged, and the spacing of described fixture block is 50 ~ 100mm, and the width of described fixture block to other end convergent, and is provided with fillet at the seamed edge place of relatively wide one end by one end.
The beneficial effects of the utility model are:
(1) adopt gear drive, can ensure that instantaneous transmission ratio is constant, stationarity is higher, transmit motion accurately and reliably, the power that transmits and velocity interval is comparatively large, compact conformation, reliable operation, larger gearratio can be realized simultaneously; Transmission efficiency is high, long service life;
(2) utilize incomplete mechanism gear mechanism, make reinforcing bar in BENDING PROCESS, realize the stressed of interval, furtherly, the theory of Combining material mechanics, ensures not stress the metastable time period of short duration, the internal stress of balanced reinforcing bar inside, reduces the screen resilience of reinforcing bar;
(3) for gear drive has been equipped with corresponding oil groove, ensure that the function of lubrication, extend gear life.

Detailed description of the invention
Embodiment: a kind of bending apparatus of vertical bending machine, see Fig. 1 ~ Fig. 4, described bending apparatus comprises the central shaft 2 that connects and motor 10 and the gear transmission unit of reductor 9, the rotating disk 5 coordinated with this gear transmission unit output shaft, rotating disk 5 are arranged and passes the eccentric shaft 11 that rotating disk 5 card arranges.
Described rotating disk 5 card is provided with through hole, and described eccentric shaft 11 is in described through hole, and is connected with the driver part making it move axially along through hole.In the present embodiment, driver part is hydraulic cylinder.
Described gear transmission unit comprises incomplete gear mechanism.Be equivalent to, BENDING PROCESS is interval, in the process of interval, overcomes the screen resilience of reinforcing bar.
Described bending apparatus also comprises oil groove, and this oil groove correspondence is in the below of described partial gear.Ensure that the lubrication of the gear teeth.This oil groove is arranged on cabinet 1.
Described driver part is liquid/gas cylinder pressure.
Rotating disk 5 is provided with limit switch, and this limit switch and described power source form current control loop, control the keying of described power source.Control bar bending to required angle.
The central shaft of described bending apparatus comprises two fixture blocks be oppositely arranged 14, and the spacing of described fixture block 14 is 50 ~ 100mm, and the width of described fixture block 14 to other end convergent, and is set to fillet at the seamed edge place of relatively wide one end by one end.The convergent of width is the relative equilibrium in order to ensure reinforcing steel bar bear, and fillet is to ensure the smooth of contact surface, stablizing of BENDING PROCESS.
In the present embodiment, the kind of drive changes gear drive into by V belt translation, and the kind of drive is more steady effectively.
In the course of work, motor 10 in cabinet 1, drive output shaft 6 to rotate by gear transmission unit, and then drive the rotation of the rotating disk coordinated with output shaft 6, rotating disk is nested with setting-up eccentricity axle 11, during bar bending, central shaft 2 and eccentric shaft 11 form two corresponding point of applications, are bent by reinforcing bar, and eccentric shaft 11 can by the cylinder ejector on the cabinet of inside simultaneously, this structure and limit switch acting in conjunction, control bending angle.
When reinforcing bar enters position to be processed, as shown in Figure 2, when reinforcing bar will carry out bending, driving mechanism drives eccentric shaft 11 outwards to eject to the duty of bending apparatus, as shown in Figure 2, positions reinforcing bar, thus applies external force to it further, makes it be out of shape.
