具体实施方式 detailed description

图1是本实用新型公开的一个实施例。 FIG 1 is an embodiment of the present invention disclosure. 双箍筋模钢筋弯箍机的主轴21末端花键与减速器7的花键套11配合,弯箍转盘2用螺钉24固定在主轴21前端的端部;双箍筋模1由螺钉固定在限位套20上,双箍筋模1与限位套20之间有铜套23,铜套23的外环有台肩。 Dual modulus main stirrup bar bending machine hoop spline end 21 of the reduction gear 7 mating spline sleeve 11, the main shaft 2 is fixed to distal end 21 by screws 24 clamps rotary bending; bis stirrups die 1 is fixed by a screw stopper sleeve 20, there are 20 pairs of stirrup between the mold 1 and the stopper sleeve 23 copper sleeve, copper sleeve has a shoulder 23 of the outer ring. 弯箍转盘2安装双箍筋模1的中心孔也有台肩,该台肩与铜套23外环台肩相配合防止双箍筋模1轴向窜动。 Bending hoop turntable 2 mounting stirrups double center hole die 1 also has a shoulder, the shoulder of the copper sleeve 23 of the outer ring shoulder cooperating die to prevent an axial movement bis stirrups. 双箍筋模1的左侧尾部镶嵌在机架的滑槽29中,使双箍筋模1只能左右移动不能转动。 Left tail die 1 bis stirrups embedded in the slide rack 29 in the die 1 bis stirrups move around can not rotate. 弯箍转盘2上用螺钉28固定导轨25,导轨25内用方螺母27固定弯箍轴3,弯箍轴3上的转套26可更换,更换后由螺钉固定。 Bending hoop turntable 25 by screws 28 fixing the guide rail, the inner rail 225 with square nut 27 is fixed hoop bending shaft 3, the rotating cylinder 3 on the bending hoop shaft 26 can be replaced, the replacement is fixed by screws. 气缸10的缸体用销轴9与机架的固定耳板6连接,气缸10的活塞杆通过接头13、销轴14、连杆15与偏心轴17连接在一起,偏心轴17安装在偏心套杯18之内,偏心轴17下端轴与滚轮19相配合。 Cylinder block 10 by pins connected to the frame 9 of the fixing lug plate 6, the piston rod of the cylinder 10 by the fitting 13, pin 14, connecting rod 15 connected with the eccentric shaft 17, the eccentric shaft 17 is mounted in an eccentric sleeve the inner cup 18, the lower end of the eccentric shaft 17 and the roller shaft 19 cooperates.

双箍筋模1前表面蝶形结构有中间槽,中间槽的左侧两边凸台有15°的斜度,右侧两边有圆弧状凸台,圆弧凸台的直径是弯曲钢筋直径的7倍。 Dual mode stirrup structure 1 the front surface of the butterfly intermediate groove, intermediate groove on both sides of the left boss has a slope of 15 °, on both sides of the right diameter of the arc-shaped boss, the boss is curved arcuate bar diameter 7 times.

4主轴21由伺服电机4通过联轴器5和减速器7驱动旋转,带动弯箍转盘2和固定在其上面的弯箍轴3 —起旋转,双箍筋模1固定不动。 4 spindle 4 by a servo motor 21 driven to rotate by coupling 7 and a reducer 5, driven by the turntable 2 and the bending hoop fixed thereon hoop bending axis 3 - from rotating, double stirrups stationary die 1. 通过主轴21的顺时针和逆时针方向的旋转,实现钢筋顺时针和逆时针方向180°范围内任意角度的弯曲。 Clockwise and counterclockwise by the rotation of the main shaft 21, is bent to achieve any angle within the range of 180 ° clockwise and counterclockwise steel.

主轴21通过偏心轴17的作用实现轴向伸縮,同时可带动弯箍转盘2和双箍筋模1 一起移动,进而实现弯曲后钢筋的左移,得到更精确的剪切长度。 Spindle 21 is achieved by the eccentric shaft 17 axial stretching, bending hoop while driving the turntable 2 and the die 1 bis stirrups are moved together, so as to realize the left after the bending reinforcement, to give a more precise cut length. 在弯曲不同直径的钢筋时,只要更换相应的双箍筋模1和转套26,并调整弯箍轴3的径向位置,便可实现。 When the bending of steel of different diameters, as long as the replacement of the corresponding bis stirrups die 1 and the rotating cylinder 26, and adjusts the radial position of the shaft bending hoop 3, can be realized.

顺时针弯曲时,弯箍轴3初始位置停在钢筋上方,弯箍转盘2在主轴21的带动下顺时针旋转,钢筋在弯箍轴3施加的弯曲力的作用下顺吋针弯曲。 Clockwise bending, bending hoop initial position of the shaft 3 stops at the top of steel, bending hoop turntable 2 rotates clockwise driven spindle 21, the cis-inch steel needle under the effect of bending of the bending force exerted 3 hoop bending axis. 同时主轴21的旋转由伺服电机4控制,伺服电机4由角度传感器控制,直到弯曲所要求的角度,弯箍转盘2返回初始位置。 21 while rotating the spindle servo motor 4 controlled by the servo motor 4 controlled by the angle sensor, until the desired bending angle, bending hoop turntable 2 returns to the initial position. 逆时针弯曲时,弯箍转盘2在主轴21的带动下先向后縮,然后由伺服电机4驱动顺时针旋转,直到弯箍轴3绕到钢筋下方,弯箍转盘2重新伸出,实现换向。 Counterclockwise bending, bending hoop turntable 2 Xianxiang receding driven spindle 21, and driven by a servo motor 4 rotates clockwise, until the lower bending steel hoop around the shaft 3, re-bending hoop projecting the turntable 2, are enabled for to.

伺服电机4带动主轴21和弯箍转盘2旋转,这时双箍筋模1由于镶嵌在机架的滑槽29中而不能转动。 The servo motor 4 and the drive spindle 21 bending hoop turntable 2 is rotated, then double stirrups embedded in the mold 1 due to the sliding rack 29 can not rotate.

弯箍转盘2上有刻痕,用来度量弯箍轴3的径向位置,同时增大弯箍轴3和弯箍转盘2之间的摩擦。 Bending hoop on the turntable 2 nicks, used to measure the radial position hoop bending axis 3, while increasing friction between the shaft 3 and the bending hoop hoop bending turntable 2. 双箍筋模2尾部的斜度是为了方便钢筋的进给。 Dual slope stirrup end of the mold 2 is to facilitate feeding steel.
