A kind of cast aluminium section bar hanging tool structure
Technical field
the present invention relates to aluminium section bar production technical field, be specially a kind of cast aluminium section bar hanging tool structure for anodic oxidation treatment.
Background technology
at present, aluminium section bar needs to carry out oxide treatment in process of production, makes its surface form sull.Metal oxide film has changed condition of surface and performance, as surface colour, improve erosion resistance, strengthen wear resistance and hardness, protection metallic surface etc., aluminium after anodic oxidation or its alloy, its hardness and wear resistance are improved, strengthen corrosion resistance, existing oxide treatment aluminium section bar hanger, as the Chinese patent that notification number is 203474937U has been announced a kind of aluminium section bar anodizing hanging device, this kind of hanger is all generally static being placed in oxidation electrolyte, due in oxidising process, in electrolytic solution, for example sulfuric acid concentration changes in the difference of regional, and generated reactive gas all has considerable influence to the formation of oxide film, particularly cast aluminium section bar, can cause the oxide film of aluminium section bar surfaces externally and internally inhomogeneous and affect follow-up painted, the techniques such as wearing and tearing, cause the larger difference of physicals, and make the asymmetry of aluminium section bar one-piece construction and performance, cause aluminium section bar of low quality, easily impaired.
Summary of the invention
the object of this invention is to provide a kind of stabilized structure, articulate stable, easy for operation and can make cast aluminium shape surface form the cast aluminium section bar hanging tool structure of uniform oxidation film layer.
above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of cast aluminium section bar hanging tool structure, comprise rotatably can translation main support rod, described main support rod is provided with two and articulates bar, be respectively that a left side articulates bar and the right side articulates bar, a described left side articulates bar and the described right side and articulates bar and be provided with relative to locating the hanging joint that articulates aluminium section bar end one by one.
in technique scheme, can make aluminium section bar stably by hanging joint effective location, rotation by main support rod and translation realize cast aluminium section bar surfaces externally and internally and form the high evenness of oxide film film, because electrolytic solution is in reaction process, the one-tenth branch of for example sulfuric acid changes, regional there will be difference, and in reaction process, there is a γ-ray emission, can affect equally the uniformity coefficient such as oxide thickness and density that oxide film forms at aluminium section bar surfaces externally and internally, this technical scheme can finely address this problem.
as to of the present invention preferably, hanging joint comprises the circular acid and alkali-resistance inner core that is fixed on the pie articulating on bar, the periphery of described circular acid and alkali-resistance inner core has ring groove, and described ring groove is embedded with a circle acid and alkali-resistance water-swellable circle, and described circular acid and alkali-resistance inner core center has central through hole.When cast aluminium section bar being installed on hanging joint behind location and putting into electrolytic solution, acid and alkali-resistance water-swellable circle runs into water and expands, make the inner ring of acid and alkali-resistance water-swellable circle fore-set cast aluminium section bar, and cast aluminium section bar is fixed firmly, rotating the peaceful Cheng Zhongye of moving past at main support rod there will not be loosening, and do not affect surfaces externally and internally order and form oxide film, when anode oxidation process finishes, main support rod in hanging tool structure is taken out and dried together with articulating bar and aluminium section bar above, acid and alkali-resistance water-swellable circle will shrink, be convenient to taking off of aluminium section bar.
as preferably one end of main support rod is connected to a rotary electric machine to of the present invention, described rotary electric machine is installed on transfer table, and described transfer table is connected with hydro-cylinder, and described hydro-cylinder and described rotary electric machine are connected to numerical control device.Realize automatization control by numerical control device control rotary electric machine and hydro-cylinder.
as to of the present invention preferably, main support rod be positioned at that a left side articulates bar and the right mid-way place that articulates bar is provided with the stiffening web perpendicular to described main support rod, described stiffening web is provided with the support ring corresponding with hanging joint.Strengthen hanging tool structure intensity, and be also convenient to aluminium section bar and carry out placement positioning.
as to of the present invention preferably, the right side articulates bar and is removably mounted on main support rod, a left side articulates bar and stiffening web is fixedly mounted on main support rod, or a left side articulates bar and be removably mounted on main support rod, and a left side articulates bar and stiffening web and is fixedly mounted on the right side and articulates on bar.Be convenient to aluminium section bar to settle, detachable installation can adopt the structure of bolt, nut, and articulates bar or a left side on the right side and articulate and on bar and main support rod, have corresponding screw.
as to of the present invention preferred, articulate on bar and comprise that two with upper rack posts.Carry more aluminium section bar.
as to of the present invention preferably, the angle forming between the same adjacent struts articulating on bar is 30 degree-45 degree.Rotate peaceful move past journey in keep move stability, reduce the larger amplitude of the stable vibrations of cloth.
as to of the present invention preferably, rotary electric machine is furnished with reducing motor.Improve moment of torsion, form enough torsion and remove to carry more aluminium section bar.
as preferably circular acid and alkali-resistance inner core is copper inner core or ceramic inner core to of the present invention, acid and alkali-resistance water-swellable circle is expanded rubber circle or the wood circle that expands.Material benefit is durable.
as to of the present invention preferably, rotary electric machine is either-rotation motor.Realize both direction running, further improve the oxide film degree of uniformity that aluminium section bar surfaces externally and internally forms.
beneficial effect of the present invention: this hanging tool structure is firm, articulate stable, in operational process bad shake little, little to the damage of hanger itself.Easy for operation, and can make cast aluminium shape surface form oxidation film layer very uniformly, meanwhile, can effectively reduce the usage quantity of electrolytic solution effective constituent, energy-conserving and environment-protective.
