The vertical type steel-bar bending machine of compound bending
Technical field
It is the vertical type steel-bar bending machine that the utility model relates to, particularly be the vertical type steel-bar bending machine of compound bending.
Background technology
At present, the vertical type steel-bar bending machine of prior art comprises: frame; The bending machine casing; Drive the power transmission driving mechanism that the bending machine casing slides on frame; The bending machine casing is provided with bending axis and central shaft, and described central shaft is fixed on the panel of bending machine casing, and bending axis is positioned at the eccentric part of rotating power source, and the pivot of rotating power source is same as the center of central shaft.During work, reinforcing bar is inserted between bending axis and the central shaft, bending axis rotates around central shaft under the drive of rotating power source, with bar bending.
During the bending of the vertical type steel-bar bending machine of prior art continuous bend reinforcing bar, can only be towards a direction bending, promptly reinforcing bar is below crooked head, and behind the moment reinforcement, crooked head resets earlier crooked head clockwise, and reinforcing bar moves forward, and crooked head is moment reinforcement clockwise again.When as if the opposite direction moment reinforcement, have only artificial mobile reinforcing bar above crooked head, the bending head is rotated counterclockwise moment reinforcement in the other direction.On prior art vertical type steel-bar bending machine, realize that with artificial mobile reinforcing bar back-flexing exists labour intensity big, ineffective defective.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, is to provide a kind of and can be simultaneously reinforcing bar be realized compound bending, the vertical type steel-bar bending machine of automaticity height, compound bending that efficient is high.
The technical scheme that solves the problems of the technologies described above is: a kind of vertical type steel-bar bending machine of compound bending, and described vertical type steel-bar bending machine comprises: frame; The bending machine casing; Drive the power transmission driving mechanism that the bending machine casing slides on frame; The bending machine casing is provided with bending axis and central shaft, described central shaft is fixed on the panel of bending machine casing, described bending axis is positioned at the eccentricity of central axis place and is fixed on the swing arm eccentric orfice, the centre bore of swing arm and central shaft center coexist on the line, be fixed on an end of power transmission shaft in the centre bore of swing arm, the power transmission shaft other end connects rotating power source; Also be fixed with telescoping cylinder in the swing arm, the piston rod of telescoping cylinder connects bending axis, and telescoping cylinder drives bending axis and moves in the swing arm eccentric orfice.
The beneficial effects of the utility model are: the utility model overcomes the defective of prior art, remedy prior art vertical type steel-bar bending machine can not be on a reinforcing bar compound bending defective continuously.The utility model need not artificial mobile reinforcing bar compound bending, reduces labour intensity, increases work efficiency.The utility model also has simple in structure, and is easy to maintenance, and stable working is saved energy consumption, the advantage that processing cost is low.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model front view; Fig. 2 is the vertical view of the partial cutaway of Fig. 1.
As shown in the figure, the utility model provides a kind of vertical type steel-bar bending machine of compound bending, and described vertical type steel-bar bending machine comprises: frame 15; Bending machine casing 10; Drive the power transmission driving mechanism 1 that bending machine casing 10 slides on frame 15; Bending machine casing 10 is provided with bending axis 12 and central shaft 13, and described central shaft 13 is fixed on the panel 4 of bending machine casing.
Described bending axis 12 is positioned at central shaft 13 eccentric parts and is fixed on swing arm 8 eccentric orfices, and the centre bore of swing arm 8 and central shaft 13 centers coexist on the line, is fixed on an end of power transmission shaft 9 in the centre bore of swing arm 8, and power transmission shaft 9 other ends connect rotating power source; Also be fixed with telescoping cylinder 6 in the swing arm 8, the piston rod 6a of telescoping cylinder 6 connects bending axis 12, and telescoping cylinder 6 drives bending axis 12 and moves in swing arm 8 eccentric orfices.
The structure that described telescoping cylinder 6 is fixed in the swing arm 8 is: swing arm 8 one sides are fixed with " U " font air cylinder fixed plate 7, and telescoping cylinder 6 is fixed on the air cylinder fixed plate 7, the fixedly connected bending axis 12 of piston rod 6a floating junction of telescoping cylinder 6.
Described rotating power source comprises: drive unit 3 outputs connect small synchronous pulley 2, and band connects small synchronous pulley 2 and big synchronous pulley 11 synchronously; Power transmission shaft 9 other ends and big synchronous pulley 11 are connected by key.Drive unit 3 can select for use servomotor to connect small synchronous pulley 2.
Above-mentioned power transmits driving mechanism 1 can select the transmission servomotor for use; Bending machine casing 10 is provided with sprocket wheel; Transmit the servomotor output and connect the sprocket wheel conveying transmission mechanism of forming by sprocket wheel and chain 5, drive bending machine casing 10 and on frame 15, slide.Chain fixed head 14 is that sprocket wheel is carried the chain fixed head that is used to connect chain in the transmission mechanism among Fig. 1.
