Abstract
The invention relates to a method for manufacturing an aluminium pan head for a spinning warp knitting machine. The method is realized by the following main steps of: smelting aluminium alloy in a smelting furnace, casting an aluminium alloy tube by virtue of centrifugal casting, casting aluminium alloy pan discs by adopting a metal mould casting way, respectively carrying out machining on the cast pan discs and the cast tube, assembling the two machined pan discs and the tube into a pan head, welding the two pan discs and the tube into a whole, finishing the welded pan head, and carrying out surface anode oxidation treatment on the finished pan head, thus a qualified pan head is obtained. Compared with an integrally cast or forged pan head, the pan head manufactured by the method in the invention has the advantages that the pan discs and the tube are respectively cast, and then the pan discs and the tube are welded into a whole in a welding way, thus the manufacturing process, equipment and mould are simpler, the production cost is greatly reduced, and the quality of the pan head is improved.
Description
Technical field
The invention belongs to processing technique field, more specifically relate to a kind of manufacture method of warp knitting machine of weaving with the aluminium coiled hair.
Background technology
Coiled hair is that weaving is used for spiral and the part through compiling through the volume field, and the quality of its quality directly has influence on the quality and the output of grey cloth.The coiled hair great majority of in the past using on the warp knitting machine are that the method with monoblock cast or forging is made, and the coiled hair of this integral manufacturing is very high to the requirement of technology, mould and equipment, makes coiled hair manufacturing cost height, and precision is low.In recent years, though the coiled hair that appearance is assembled several parts by mechanical means, such coiled hair working life is shorter.Therefore, people are seeking the coiled hair manufacture method of low-cost and high-quality always.
The patent No. is " 200510009998.2 ", and name is called the manufacture method of aluminium alloy integrated disk head, makes coiled hair with Forging Technology, and technology is comparatively complicated, consuming time.
Summary of the invention
In order to address the above problem, the invention provides the manufacture method that a kind of warp knitting machine of weaving is used the aluminium coiled hair, this method is directly carried out machined with cast blank, and manufacture craft is simple, and prepared aluminium coiled hair cost is low, the quality height.
The present invention implements by following technical solution:
A kind of warp knitting machine of weaving comprises the steps: (1) smelting aluminium alloy in smelting furnace with the manufacture method of aluminium coiled hair, casts out the aluminium alloy pipe by centrifugal casting, casts out the aluminium alloy disc by permanent mold casting; (2) disc and the pipe with casting carries out machined respectively; (3) two discs and pipe are assembled into coiled hair after, with welding method that they are integrally welded; (4) coiled hair is carried out fine finishining; (5) coiled hair after the fine finishining is carried out surperficial anodized.
Described manufacture method is carried out machined after also being included in after the described step (1) pipe of casting and disc being carried out T6 heat treatment again.
The heat treated condition of described T6 is: solid solution temperature is 450～480 ℃, insulation 2～6h, and shrend, artificial aging is 120～150 ℃, insulation 8～16h.。
The material composition of described aluminium alloy is counted with mass fraction: Zn is 3.5～5.0%, Mg is 0.8～1.8%, Cu is 0.5～1.5%, Ti is 0.01～0.10%, and B is 0.002～0.01%, impurity Si≤0.3%, Fe≤0.3%, other single impurity≤0.05%, other impurity add up to≤0.1%, and all the other are Al.
Composition Ti and B in the described aluminum alloy materials add by the Al-Ti-B fining agent.
Advantage of the present invention is: compare with the coiled hair of monoblock cast or forging, the present invention separately casts disc and pipe, and the method by welding is welded into one then, thereby the manufacturing technique of making, equipment and mold are simply a lot, greatly reduce production cost, improved the coiled hair quality.Simultaneously, alloying component has been carried out optimal design, composition Ti in the aluminum alloy materials and B add by the Al-Ti-B fining agent, adopt fining agent to add Ti and B, the further grain structure of refinement aluminium alloy, the quality of raising aluminium coiled hair.Aluminium alloy disc and pipe that casting is come out can directly use under as cast condition, also can further improve the quality by heat treatment, and system of selection is flexible.
