Abstract
The invention belongs to the technical field of an illuminator lamp post made by metal. An aluminum alloy conical pipe manufacture method includes the following steps: arranging an aluminum alloy spoiled material on an extruding press; selecting a mold hole shape of a press mold according to the wall surface thickness and maxim diameter of the conical pipe; the aluminum alloy spoiled material forms a round pipe material, a section pipe material, a semi-cut material or a plate material; using a mechanical cutter or a shearing machine to cut off the redundant parts of the round pipe material, the section pipe material, the semi-cut material or the plate material according to the conicity requirement of the conical pipe; carrying out pressing forming after arranging a standard prod cast in the round pipe material, the section pipe material, the semi-cut material or the plate material to form the conical pipe; carrying out welding sealing on the joint close of the conical pipe; aligning the conical pipe; acquiring the finished product for the aluminum alloy conical pipe after surface treatment. The invention has the advantages of few manufacture device investment and mow manufacture cost as well as flexible and convenient design which can change the diameter and wall thickness of the aluminum alloy conical pipe with lower cost by changing the mold hole shape of the press mold.
Description
Technical field
The invention belongs to the technical field of metal illuminator lamp post, specifically be meant a kind of method for producing aluminum alloy conical pipe that is used for lighting installation and the installation of traffic signals sign.
Background technology
At present, aluminum alloy conical pipe is widely used in the lighting installation of occasions such as urban road, highway, open deck and the installation of traffic signals sign.The production of traditional aluminum alloy conical pipe is with the pressing of web-like aluminum alloy plate materials, cut-out, cutting (trapezoidal shape), shaping mould punch forming (taper), makes conical pipe through operations such as welding again.Wherein aluminium alloy roll bending production equipment cost is very expensive, and the investment of whole piece production line is huge, and the construction period is long, and the production cost of products height has limited promoting the use of of product.In addition, the wall thickness of the employed aluminum alloy conical pipe in different regions is that the climatic condition according to this area designs as wind speed, and because the thickness of aluminum alloy plate materials all has the size of standard for the requirement that is fit to all trades and professions, its thickness is inconvenient to adjust, and therefore can not adapt to the requirement of different regions to the wall thickness of aluminum alloy conical pipe well.
Summary of the invention
The object of the present invention is to provide a kind of small investment of production equipment, production cost is low, conical pipe thickness is convenient to adjust method for producing aluminum alloy conical pipe.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method for producing aluminum alloy conical pipe may further comprise the steps:
(1) with extruder on the aluminium alloy stock;
(2) the nib shape of selecting extrusion die according to the wall thickness and the maximum gauge of conical pipe, the aluminium alloy stock forms pipe material, special section tubular product, half opening section bar or sheet material through the extruder hot extrusion;
(3) require to go the redundance of pipe material, special section tubular product, half opening section bar or sheet material according to the tapering of conical pipe with mechanical cutter or shearing machine cutting;
(4) in pipe material, special section tubular product, half opening section bar or sheet material, put into the laggard capable compression moulding of standard prod cast, form conical pipe;
(5) joint close to conical pipe carries out solder up;
(6) alignment conical pipe;
(7) obtain the aluminum alloy conical pipe finished product after the surface treatment.
The present invention is applied to the manufacturing of aluminum alloy conical pipe with extrusion process, and does not need to use large-scale aluminum alloy plate materials production equipment, and investment of production equipment is little, and production cost is low.When the present invention produced, the nib shape that only need change extrusion die can change the diameter and the wall thickness of aluminum alloy conical pipe, and flexible design is easy to adjust.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail, but does not constitute any limitation of the invention.
Described method for producing aluminum alloy conical pipe may further comprise the steps:
(1) with extruder on the aluminium alloy stock; The aluminium alloy stock can be selected according to the specification requirement of product such as physical strength and chemical composition, and the aluminium alloy stock is solvable to be cast bar-shaped or hollow bar-shapedly, hollowly bar-shapedly is convenient to extruding and forms tubing.
(2) the nib shape of selecting extrusion die according to the wall thickness and the maximum gauge of conical pipe, nib can be rectangle, annular, abnormity etc., the aluminium alloy stock is through extruder extruding formation pipe material or sheet material as shown in Figure 4 and Figure 5, also available extrusion die as shown in Figure 6 is squeezed into special section tubular product or extrusion die as shown in Figure 7 is squeezed into the half opening section bar, pipe material and heterotype tubing are difficult for bending when extruding, half opening section bar and sheet material only need cut off when carrying out cutting on one side, and technology is comparatively simple.
(3) as shown in Figure 4 and Figure 5, require to go the redundance (dash area among the figure) of pipe material or sheet material with mechanical cutter or shearing machine cutting according to the tapering of conical pipe, also can make cutting methods such as electricity consumption is molten, gas carry out cutting, carry out shaping after the cutting again, so that next step compression moulding.Adopt as shown in Figure 6 the material that carries out after the extrusion modling with extrusion die shown in Figure 7 to have a plane, conveniently carry out trimming operation.
(4) as shown in Figure 4 and Figure 5, be pressed put into standard prod cast 6 in pipe material or sheet material after, form conical pipe, the compression moulding operation of special section tubular product, half opening section bar is also identical.
(5) joint close to the conical pipe after the compression moulding carries out solder up,
(6) alignment conical pipe carries out alignment by the pressure straightening machine of hydraulic pressure or common mechanical transmission, eliminates the distortion that welding produces.
(7) surface treatment, as polishing, processing such as surface oxidation-resistant obtain aluminum alloy conical pipe 1 finished product as depicted in figs. 1 and 2.
As Fig. 1, Fig. 2 and shown in Figure 3, the nib 4 of extrusion die 3 is provided with the groove 5 of a plurality of formation reinforcements 2, when extrusion process, can form reinforcement 2 longitudinally in the one side of pushing the material that comes out, reinforcement 2 can be strengthened the intensity of aluminum alloy conical pipe 1, prevent to be subjected to external force and bending takes place to be out of shape, also can reduce raw-material use.
