Abstract
The utility model discloses a pipe bender for bending the pipes. The pipe bender comprises a machine body (3), a turning arm (1) and a turning arm driving device, wherein the turning arm driving device comprises a revolving component (4) for driving the turning arm (1) in the same pace with the turning arm; and the front of the revolving component (4) for driving the turning arm (1) in the turning arm driving device is partially eliminated. The revolving component (4) is either a gear or a worm gear.
Description
Technical field
The present invention relates to a kind of bending machine, especially a kind of bending machine that the pivoted arm drive unit is arranged.
Background technology
Electric pipe bender in the market all is the bending machine that the pivoted arm drive unit is arranged, and the pivoted arm drive unit much is a gear ﹠ rack structure, and gear is as the pivoting part that drives pivoted arm, and itself and pivoted arm turn round synchronously.Gear is a full circle, does not expose in order to make the gear front portion, and it is bigger that pipe bender head need be done, and some pipe fittings will be interfered with head in BENDING PROCESS, influence bend pipe.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of less bending machine that can do head, with reduce pipe fitting in BENDING PROCESS with the interference of head
For solving the problems of the technologies described above, bending machine of the present invention, comprise fuselage, pivoted arm, pivoted arm drive unit, the pivoted arm drive unit comprises that one drives the pivoting part of pivoted arm with synchronous being used for of pivoted arm, is characterized in that: the front portion that is used for driving the pivoting part of pivoted arm in the described pivoted arm drive unit is removed a part.
As a kind of preferred structure of the present invention, the pivoting part that is used for driving pivoted arm in the pivoted arm drive unit of above-mentioned bending machine is a gear.
As another kind of preferred structure of the present invention, the pivoting part that is used for driving pivoted arm in the pivoted arm drive unit of above-mentioned bending machine is a worm gear.
Above-mentioned bending machine is owing to be removed a part with the front portion that is used for driving the pivoting part of pivoted arm in the pivoted arm drive unit, it is less that pipe bender head is done, the gear front portion is not exposed, when bend pipe, just can reduce pipe fitting in BENDING PROCESS with the interference of head.
Description of drawings
Below in conjunction with accompanying drawing one embodiment of the present invention are described.
Fig. 1 is the schematic diagram of one embodiment of the present invention.
Fig. 2 is the schematic diagram of first kind of preferred structure that is used for driving the pivoting part of pivoted arm in the embodiment of the present invention.
Fig. 3 is the schematic diagram of second kind of preferred structure that is used for driving the pivoting part of pivoted arm in the embodiment of the present invention.
The specific embodiment
Fig. 1 shows one embodiment of the present invention.Main shaft 2 is installed in fuselage 3 front portions, and pivoted arm 1 is installed on the main shaft 2, and main shaft 2 drives pivoted arm 1 when rotating and rotates simultaneously.Fuselage 3 front portions, main shaft 2, pivoted arm 1 constitute head.Main shaft 2 lower ends are equipped with pivoting part 4, and power rail 5 promotes pivoting part 4 and rotates, and pivoting part 4 drives main shaft 2 and pivoted arm 1 rotates.In the present embodiment, the front portion of pivoting part 4 is removed a part, like this fuselage 3 front portions can do less, pivoting part 4 also can not be exposed to the outside of fuselage 3 front portions, when bend pipe, just can reduce pipe fitting in BENDING PROCESS with the interference of head.
Fig. 2 shows first kind of preferred structure of the pivoting part 4 that is used for driving pivoted arm in the embodiment of the present invention.In this preferred structure, pivoting part 4 is an anterior gear that removes a part, and power rail 5 is a toothed rack.
Fig. 3 shows second kind of preferred structure of the pivoting part 4 that is used for driving pivoted arm in the embodiment of the present invention.In this preferred structure, pivoting part 4 is an anterior worm gear that removes a part, and power rail 5 is a worm screw.
