Abstract
The invention relates to a manufacturing method of a compressor volute casing. The method comprises the following steps: establishing a three-dimensional model of the compressor volute casing, introducing the three-dimensional model into rapid molding equipment, directly sintering out a shape of the compressor volute casing of a plastic material instead of a sand core by using a powder sintering technology and a laser numerical control technology, and finishing casting and molding of the compressor volute casing through a traditional investment casting method. As the mold manufacturing and sand core making process is eliminated in the method, the trial period in the production is reduced, the efficiency is increased and the production cost is reduced; and the manufacturing method provided by the invention is especially suitable for trail production in a development phase and medium and small-scale production. Through the adoption of the manufacturing method provided by the invention, the manufacturing period is reduced, and the manufacturing precision of the product can be also guaranteed. Compared with similar domestic methods, the manufacturing method provided by the invention has the advantages as follows: as technological design and manufacture of a wooden mold and the making process of the sand core are eliminated, an energy-saving and environment-friendly effect is taken.
Description
Technical field
The invention belongs to the forming processing technology field, be specifically related to a kind of manufacture method of compressor volute of booster.
Background technology
The method of making wooden model is adopted in the casting of general vehicular engine supercharger air compressor spiral case usually, then carries out the making of core, carries out at last the aluminum material casting and forms.Concrete steps are: at first need to carry out Design of Dies according to the shape of compressor volute, the assembled scheme of consideration die casting, the die joint of mould, pattern draft etc., then make the crust of snail like mould and the core of complex-shaped thin-walled inner chamber runner by machining center equipment and hand grinding, then the combination by a plurality of die modules, finish the making of core, be grouped together at last and carry out the moulding by casting of conventional casting aluminium material, obtain the compressor volute of aluminum material.Adopting its shortcoming of this method is that process flow is various, complex procedures, and the process-cycle is long, and what have must adopt manual wooden model repair, and manual intervention is large, inner chamber runner low precision, mould and die accuracy can't guarantee.
Summary of the invention
The present invention is in order to solve the problems of the technologies described above, and a kind of shape of compressor volute that laser Numeric Control Technology direct sintering replaces the plastic material of core of using is provided, and finishes the manufacture method of the moulding by casting of compressor volute by conventional investment casting method again.
The technical solution used in the present invention is: a kind of manufacture method of compressor volute may further comprise the steps:
(1) sets up the threedimensional model of compressor volute: according to product two dimension drawing, adopt general modeling software to make the threedimensional model of compressor volute, according to its structure, what be divided into two from the center dissects, consider the casting contraction, model is amplified respectively in 1.7% ratio;
(2) import computer: the threedimensional model that step (1) is obtained imports in the computer system of rapid forming equipment, determines the sintering parameters such as sintering bottom surface, wall thickness, coordinate origin with reference to concrete size and the shape of compressor volute;
(3) laser sintered: as first the 0.25mm slicing treatment to be carried out in the threedimensional model of step (2), then carry out the selective laser sintering of polystyrene plastics material, granularity selection 160 orders of polystyrene, in sintering process, the sweep speed of laser is set as 2200 mm/s, spreads speed 210 mm/s of powder, feed allowance 0.04mm, conversion factor 144, laser power 18kw; Begin 125 ℃ of temperature of the roasting end, 5 ℃ of every burning 25 layers of roasting end drop in temperatures no longer descend when temperature drops to 50 ℃, and keep constant temperature to finish to sintering always, 35 minutes time, in 2 hours temperature slowly are down to room temperature after sintering is finished and take out sintering spiral case spare;
(4) the floating powder of cleaning: the floating powder of cleaning after sintering is finished is beneficial to effective control of precision and surface roughness;
(5) being stained with wax processes: after 62 ℃ of low temperature heating paraffin, the compressor volute of step (4) is carried out being stained with wax the first time, place after 30 minutes, again low temperature heating paraffin to 66 ℃ is carried out being stained with the second time wax, place and carried out the reconditioning processing in 6 hours, to improve its surperficial fineness and dimensional accuracy thereafter;
(6) coating, cleaning and dewaxing: the compressor volute of step (5) is carried out respectively conventional hot investment casting front coating, cleaning and dewaxing treatment;
(7) fix casting: 2 half formworks after step (6) is dewaxed make up fixing, adopt conventional casting method, finish integral cast.
The present invention is by setting up the threedimensional model of compressor volute, import rapid forming equipment, adopt sintered powder technique, use the shape of compressor volute that laser Numeric Control Technology direct sintering goes out to replace the plastic material of core, finish again the moulding by casting of compressor volute by conventional investment casting method.Because the method has been saved the manufacturing of mould and the manufacturing process of core, has reduced the production trial-produce period, has improved efficient, has reduced production cost, the method is particularly suitable for the trial-production of development and the production of small batch.Its method not only shortens the manufacturing cycle, can also guarantee the accuracy of manufacture of product.Compare with domestic colleague, omitted technological design, the manufacturing of wooden model, the manufacturing process of core, played the effect of energy-conserving and environment-protective.
