Abstract
The utility model provides a special small-radius pipe bending machine, which comprises a machine body, a heating coil, a middle-frequency power supply, a rocker arm and a hydraulic control system. The special small-radius pipe bending machine is characterized in that a resistance loading mechanism is added on the pipe bending machine, a certain resistance moment is exerted on the rocker arm so that the rocker arm exerts a reverse force on the bending surface under the controlled resistance effect, the bending surface is thickened, the resistance loading mechanism consists of a circular arc-shaped guide, a traction rope and a resistance hydraulic cylinder, the resistance hydraulic cylinder provides the resistance moment through dragging the rocker arm by the traction rope, and the circular arc-shaped guide is used for guiding the traction rope. The special small-radius pipe bending machine is used for reducing the thickness reduction quantity of an outer arc wall in the small-radius pipe pushing manufacturing process so that the thickness reduction quantity of the outer arc wall conforms to the standard requirement.
Description
Technical field
Pipe fitting, bend pipe, machinery.
The present invention relates to minor radius bend pipe (elbow) manufacturing equipment, particularly a kind of pushing equipment of minor radius bend pipe, controls the attenuate amount of outer arc wall by mechanical mechanism.
Background technology
In mechanical engineering, the application of arm-type bending machine is very general, but when bending minor radius (little R) bend pipe, the phenomenon of bend pipe outer arc attenuate can occur, and when elbow radius is caliber 1.5 times time, attenuate amount has reached 23% left and right, and attenuate amount exceeds standard.For this reason, need a kind of minor radius bend pipe pushing equipment that can control attenuate amount.There is no at present the arm-type bending machine that attenuate amount is controlled.
Summary of the invention
The object of the invention is to design a kind of special equipment of minor radius bend pipe, in minor radius bend pipe pushing process, reduce the attenuate amount of outer arc wall, make the attenuate amount of outer arc wall meet standard-required.
In order to achieve the above object, technical scheme of the present invention is: a kind of special-purpose small-radius pipe bender, comprise lathe bed, heating collar, intermediate frequency power supply, rocking arm, hydraulic control system, it is characterized in that increasing Resistance-load mechanism on bending machine, give the certain moment of resistance of rocking arm, make rocking arm to flexure plane, apply opposite force under controlled drag effect, flexure plane is thickened, described Resistance-load mechanism is comprised of circular arc guiding, pull rope and resistance hydraulic cylinder, resistance hydraulic cylinder draws rocking arm by pull rope the moment of resistance is provided, and circular arc guiding is used for the pull rope that leads.

pull rope,
steel pipe.
The operation principle of the bending machine of the present embodiment and the technology of the present invention feature is as follows:
Work as steel pipe
after being placed on the processing stations on bending machine, 5. heating in medium frequency circle heats steel pipe
, steel pipe
after being heated to predetermined temperature, 1. ejector sleeve mechanism promotes steel pipe
advance, steel pipe
crooked gradually under rocker structure effect 3., along with ejector sleeve mechanism moving ahead continuously 1., 9. rocker structure does circular motion, steel pipe
also along with being configured as bend pipe.When 1. ejector sleeve mechanism advances, 9. resistance hydraulic cylinder passes through pull rope
to flexure plane, apply the required moment of resistance, the shaping of limit flexion face, makes the wall thickness thickening of flexure plane outer arc.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
