Abstract
The utility model discloses a steel bar bender, comprising an angle regulator (1), a work disc (7), an electric motor (17) and a box (18), with the differences that the output axis of the electric motor (17) is sleeve-arranged with a small belt pulley (16) which is connected with a big belt wheel (14) assembled on a long tooth axis (6) by a triangle belt (15); the teeth on the long tooth axis (6) matches and meshes with the teeth of a pinion (5) assembled on a short tooth axis (4); the teeth of the short tooth axis (4) matches and meshes with that of a gearwheel (2) assembled on a small mandrel (3), and the top of a center axis (3) is jacketed by the work disc (7),. Thus, the utility model becomes more competitive in markets and is particularly applicable for the construction trade, with simplified structure, smaller size, less weight, saved material, production time and lower price.
Description
Affiliated technical field:
The utility model relates to a kind of building machinery, particularly a kind of angle-bender.
Background technology:
The angle-bender that current China building trade is generally used is by motor transmission carrier gear basically, and the worm screw in the transmission worm gear case again exports moment on the newel scratch diskette by worm gear and realizes bar bending; The change rate of bending is to finish by the rigging position of the big pinion of transposing gap bridge; The adjusting of angle of bend is to lean on the worm screw of the small gear bar of angle demodulator bottom installation and big worm gear to be connected transmission to carry out.Its defective is that complex structure, volume are big, complete machine is heavy, manufacturing cost is high.
The invention task:
The purpose of this utility model be exactly to provide a kind of improved, simple in structure, volume is little, in light weight, performance good, cost is low angle-bender.
The purpose of this utility model is achieved in that a kind of angle-bender, form by angle demodulator (1), scratch diskette (7), motor (17), casing (18), it is characterized in that: suit small belt pulley (16) on motor (17) output shaft is connected with big belt pulley (14) on being sleeved on long tooth axle (6) by V belt (15); Tooth on the long tooth axle (6) and the tooth collocation engagement that is sleeved on the pinion (5) on the short tooth axle (4); The tooth of short tooth axle (4) and the tooth collocation engagement that is sleeved on the gear wheel (2) on the little axle (3), central shaft (3) upper end suit scratch diskette (7), the lower end of central shaft (3) also is equipped with sprocket shaft II (13), sprocket shaft II (13) goes up suit sprocket wheel II (12), and the sprocket wheel I (9) that is assemblied on the interior sprocket shaft I (10) of the gear (8) of angle demodulator (1) lower end by chain (11) and termination is connected.
An optimum implementation of the present utility model is: big belt pulley (14) and small belt pulley (16) are the tower belt sheave structure form of upper and lower two-layer different-diameter.
The utility model compared with prior art has the following advantages:
On the basis of guaranteeing existing all mechanical performances of angle-bender, simplify the structure, reduced volume, reduced weight, when having saved material and worker, reduced cost, make it have more the market competitiveness.

The specific embodiment:
Referring to figure, the tower small belt pulley (16) of suit on motor (17) output shaft, be connected with tower big belt pulley (14) on long tooth axle (6) axle head by V belt (15), tooth on the long tooth axle (6) meshes with the tooth collocation that short tooth axle (4) is gone up the pinion (5) of suit, tooth on the short tooth axle (4) and the tooth collocation engagement that is sleeved on the gear wheel (2) on the central shaft (3).The upper end suit scratch diskette (7) of central shaft (3), sprocket shaft II (13) is installed in its lower end, sprocket shaft II (13) suit sprocket wheel II (12), the sprocket wheel I (9) that is assemblied on the sprocket shaft I (10) in the gear (8) of angle demodulator (1) lower end by chain (11) and termination is connected.The number of teeth, modulus, the flute profile of sprocket wheel II (12) and sprocket wheel I (9) are consistent.Actual demand according to moment reinforcement, the tower big belt pulley (14) of suit is the type of the taking belt sheave structure form of upper and lower two-layer different-diameter on tower small belt pulley (16) on motor (17) output shaft and long tooth axle (6) axle head, therefore, change V belt (15) at the tower upper strata of the large and small belt pulley of tower (14) and (16) or the link position on lower floor's belt pulley, can make central shaft (3) obtain two grades of rotating speeds of 10 rev/mins and 5 rev/mins, to satisfy this machine carries out bending to the reinforcing bar of different-diameter and radical rotating speed requirement.During use, connect power supply, motor (17) rotates, drive tower small belt pulley (16), by V belt (15) transmission tower big belt pulley (14), tower big belt pulley (14) drives long tooth axle (6), long tooth axle (6) drive pinion (5), pinion (5) is with the moving and short tooth axle (4) of drive, short tooth axle (4) is with moving and transmission gear wheel (2), gear wheel (2) is with moving and transmission central shaft (3), and the scratch diskette (7) that is sleeved on central shaft (3) upper end rotates, and can carry out the bending work of reinforcing bar on the work top.The sprocket shaft II (13) that is assemblied in central shaft (3) lower end simultaneously also follows central shaft (3) and rotates and drive sprocket II (12), drive sprocket wheel I (9) by chain (11), because the number of teeth, modulus, the flute profile of sprocket wheel II (12) and sprocket wheel I (9) are in full accord, so sprocket wheel I (9) driving-chain wheel shaft I (10), and driving angle adjuster (1) rotates synchronously with central shaft (3).If need to adjust the rotating speed of scratch diskette (7), can adjust V belt (15) in the tower upper strata of the large and small belt pulley of tower (14) and (16) or the position on lower floor's belt pulley.
Claims (2)
1, a kind of angle-bender, form by angle demodulator (1), scratch diskette (7), motor (17), casing (18), it is characterized in that: suit small belt pulley (16) on motor (17) output shaft is connected with big belt pulley (14) on being sleeved on long tooth axle (6) by V belt (15); Tooth on the long tooth axle (6) and the tooth collocation engagement that is sleeved on the pinion (5) on the short tooth axle (4); The tooth of short tooth axle (4) and the tooth collocation engagement that is sleeved on the gear wheel (2) on the little axle (3), central shaft (3) upper end suit scratch diskette (7), the lower end of central shaft (3) also is equipped with sprocket shaft II (13), sprocket shaft II (13) goes up suit sprocket wheel II (12), and the sprocket wheel I (9) that is assemblied on the interior sprocket shaft I (10) of the gear (8) of angle demodulator (1) lower end by chain (11) and termination is connected.
