Description
Technical field
The rotary pressure technology field in what the utility model patent related generally to is blower fan field, what be specifically related to is a kind of new hot spinning forming technique device.
Background technology
Blower fan industry is an important industrial class in Chinese national economy, and Fan Product is also national economy, the indispensable staple product of people's lives every aspect.Nearly thousands of family of blower fan manufacturer of China, the output value exceeds 100 billion, and still can not meet the demand of domestic development, a great deal ofly also needs import, and blower fan industry still has larger development space.China's fan industry production technology is also relatively backward, for Blower Housing part as the structural members such as wind collecting unit, air duct, kuppe, shroud still adopt the methods such as punching press, stretching, distinguish, welding, polishing substantially.Its shortcoming is: A, product quality be not high, open that shape is irregular, rough surface.B, need use a large amount of mould, often kind of product as many as number mold, cost is quite high.C, develop new product namely need mold, the Operational preparation cycle is long, investment is large.D, product are difficult to large-scale development by existing weaponry and equipment restriction.E, product are by the impact of presentation quality, and the market competitiveness is poor, is particularly difficult to enter international market.State's inner blower enterprise development is swift and violent, except original state-owned leading leading enterprise, domestic each province particularly continued to bring out the blower fan enterprise of large quantities of diversified economy type, multiple size form in coastal area in recent years, and after these newly-built blower fan enterprises come into the market, pole needs technical support to stand firm; And original long-established enterprise also needs self-technique to transform and technology innovation in pole due to the impact that is subject to the market share and reduces and the aging impact of self-technique.
Because the manufacturing process of its advanced person of rotary pressure technology almost can complete shaping of most blower fan structure part, rotary pressure technology has started one of basic fundamental becoming blower fan production.The product of blower fan enterprise of China is mostly multi items, small lot.The moulds of industrial equipment investment brought wide in variety increases, and remaining high of the product cost caused, affects the raising of economic benefit.Therefore have a special spinning machining tool of universal type blower fan that can adjust arbitrarily, be applicable to sizes shape, a large amount of mould can be saved, the prioritizing selection of blower fan enterprise can be become.External blower fan is produced and is generally adopted rotary pressure technology basic structural elements mostly by mould pressing, and outside native land, blower fan presentation quality, inherent quality are all quite high.After China's entry into the World Trade Organization, in the face of squeezing into of external product, domestic fan industry, in the face of keen competition more, must be improved the quality of products, catch up with and surpass international product level, in the hope of one seat of standing to obtain on the world, state's inner blower market.Therefore in the face of severe situation that is international, domestic market, the active adoption of blower fan enterprise comprises every advanced production technology of rotary pressure technology, undergoes technological transformation as early as possible imperative to self equipment.
There is part the monopolistic market of rotary pressure technology, as the patent No.: 20081005160.8 1 kinds of butterfly shaped flow forming molding machine finishing methods, it is characterized in that being heated to by tubing on malleable temperature after 100 ~ 200 DEG C, clamping work pieces, carries out spinning; When spinning starts, axial admission is about 1/5 ~ 1/3 of pipe diameter first time, later each charging 10mm, through several times back and forth after spinning, oral area seals, then through 1 ~ 2 spinning, excises oxidized part metals material, the thorough smithwelding of oral area is shut, and an end closure completes.Adopt butterfly rotary press modelling method, maximum can spinning diameter phi 406mm, wall thickness is the large diameter thin wall pipe fitting of 6mm, the butterfly end enclosure structure that end socket is bicircular arcs transition structure, major diameter is radial direction.What this technology solved is thin-wall pipes and shorter cylinder body major axis is the machining problem that the butterfly-type end socket of radial direction carries out hot-spinning reducing.The patent No.: 20081002090.0 1 kinds of magnesium alloy sheet material flow forming and molding process, it is characterized in that carrying out rotary pressing processing to magnesium alloy plate blank (1) on spinning machine, described magnesium alloy plate blank (1) is installed on spinning machine by spinning mold (2) and jacking block (3), with spinning wheel (4), rotary press modelling is carried out to magnesium alloy plate blank (1), it is characterized in that: described flow forming and molding process comprises the following steps: 1), intercept blank: this blank is magnesium alloy plate, i.e. magnesium alloy plate blank (1); 2), magnesium alloy plate blank (1) is heated: this blank is put into heated constant temperature stove, and heating-up temperature is 300 ~ 400 DEG C, and the time is 30 ~ 60 minutes; 3), heating mould: described spinning mold (2) and jacking block (3) are heated, makes spinning mold (2) and jacking block (3) temperature rise between 240 ~ 280 DEG C; 4), plate blank material clamping: described magnesium alloy plate blank (1) is positioned on spinning mold (2), mobile jacking block (3) clamps magnesium alloy plate blank (1), and magnesium alloy plate blank (1) is spun mould (2) and jacking block (3) is fixedly clamped; 5), rotary press modelling: start spinning machine, under program control, while described spinning mold (2) rotates, described spinning wheel (4) is close to magnesium alloy plate blank (1) and generatrix direction along spinning mold (2) moves, and impels magnesium alloy plate blank (1) to be shaped to magnesium alloy semi-finished product (5); 6), finished edge: the burr (6) of magnesium alloy semi-finished product (5) are repaiied and removes, make its edge polishing; 7), following process: double finished product machining and surface treatment; 8), finished product.Adopt this technical scheme, what mainly solve is plate forming ability.The rotary pressure technology of blower fan is fewer.
Blower fan part spinning mainly contains following several forming technology: 1, drum part straight flange flange flanging forming; 2, the enlarging of drum part end horn mouth is shaped; 3, cone tank end straight flange flange flanging forming; 4, cone tank end horn mouth flanging forming; 5, plectane mesopore turns over horn mouth shaping.
Therefore, China's blower fan producer enormous amount and in the majority with medium and small producer, Technology and equipment is limited in one's ability, and in order to improve the quality of products, improve competitive power of product, carrying out work by the rotary pressing processing technology improved voluntarily, is the ability that each enterprise should possess.Conventional fabrication process is divided into three parts to make, and takes a lot of work, waste material, outward appearance be ugly.If adopt cold spinning shaping, then can cause the uneven and cracking situation in pressed part.After summing up experience, our company researcher, the workpiece needed for blower fan, has been equipped with out a kind of device of novel employing hot spinning forming technique.This kind of technology is the device be shaped, but has no relevant report.
