Abstract

The invention relates to an overall deep drawing technology of a scroll casing of a blower, including the following steps: a steel plate for deep drawing is cut into sheets with a required size; the sheet is pressed and deep drawn to a required height; a workpiece is trimmed to a set height by a punching machine, the trimmed workpiece is cut into the left and right parts of the scroll casing at one time by the punching machine; the cut left and right workpieces of the scroll casing are punched with mounting holes by the punching machine, and after being provided with the mounting holes, the left and right parts of the scroll casing are connected together by spot welding; after process molding, the scroll casing is treated with deburring, polishing, washing, examining and warehousing. The scroll casing produced by the overall deep drawing technology of the scroll casing has stable size, can lower welding difficulty, overcome the defects caused by separate machining such as excessive working procedures, complex technique, long working hours, and the like, and avoid the quality problems which are likely to occur in separate machining process such as size over-tolerance, and the like, thus improving the appearance quality and prolonging the service life of the scroll casing; therefore, the scroll casing can achieve better price advantage and higher economic benefits in market competition.

Description

Integral drawing technique of draught fan volute
Technical field
The present invention relates to the manufacture method of volute of blower, particularly the process of volute of blower integral drawing.
Background technology
In the blower fan production industry, the volute of blower that is adopted is that symmetrical two parts are formed, and adds man-hour at present, and spiral case left and right sides two parts are that separately pull and stretch, punching are to half-finished, by being welded into integral body; Along with the progress of society, people more and more pay attention to the outward appearance of product, because present split processing, the manufacturing procedure of spiral case increases, and material consumption strengthens, and causes the production cost of spiral case to improve greatly; Moreover, in the process of split processing, be difficult to control the external dimensions of part, cause the part internal flaw, thereby influenced the total quality and the service life of spiral case.
Summary of the invention
Technical problem to be solved by this invention provides the method for making integral drawing technique of draught fan volute, reaches to improve the spiral case quality, increases the service life, and reduces the purpose of manufacturing cost.
Technical problem of the present invention realizes by following technical proposal: a kind of integral drawing technique of draught fan volute, and its feature may further comprise the steps:
(1) 08F pull and stretch coiled sheet material is cut into required size with plate shearing machine, and wipes out four jiaos of excess stocks;
(2) sheet stock behind the shear angle is sent into the pull and stretch of exerting pressure in hydraulic press and the Drawing Die to the needs height;
(3) will pass through the workpiece behind the pull and stretch cuts edge on punch press to specified altitude;
(4) will on punch press, once cut into left and right sides two parts of spiral case through the workpiece of shearing the limit;
(5) will go out installing hole at punch press through the left and right sides spiral case workpiece of shearing;
(6) will partly on mash welder, weld together about the spiral case after breaking through installing hole;
(7) will carry out deburring, polishing, cleaning, check warehouse-in through the spiral case of above-mentioned machine-shaping.
Through size is unified between the left and right sides spiral case of above-mentioned spiral case integral drawing technique manufacture method manufacturing, tolerance is stable, the edge fit clearance is little, reduce the welding difficulty, thereby many defectives such as the operation that causes because of split processing is too much, complex process, worker Shi Duo have been overcome, save material, reduced production cost of products; Also avoided simultaneously because of quality problems such as the external dimensions of appearance are overproof easily in the split process, weld seam is not of uniform size, improved the presentation quality and the service life of spiral case, also made spiral case in market competition, have better price advantage and better economic benefit.
Description of drawings
Fig. 1-5 is the workpiece outline drawing of the main procedure of processing of spiral case black box.
Fig. 6 and Fig. 7 are for cutting mould and the process of incision schematic diagram.
The specific embodiment
The volute of blower lining all is that employing deep-drawing steel plate 08F-S-II is a stock, deep-drawing steel plate multiselect boiling steel, and metallographic structure is a ferrite crystal grain, quality is soft tough.Because the trend of ferrite deep-drawing steel plate local attenuation of material in drawing process is little, helps the spiral case drawing and forming.
Pull and stretch equipment mainly is hydraulic press and punch press, and embodiment selects 300 tons of hydraulic presses for use, selects 160 tons of punch presses for use.
Mold materials is selected GCr15 or Cr12MoV alloy material for use, makes punch-die according to the workpiece size.
Lubricant is selected paraffin oil for use, polyethylene film or polypropylene film.
Embodiment:
Be example now, make the left and right sides housing of spiral case with 08F-S-II deep-drawing steel plate.
(1) with the trade mark for 08F-S-II thickness is the deep-drawing steel plate of 0.9mm, be cut into 940 * 480mm sheet stock, and wipe out four jiaos, become the octagonal sheet material;
(2) material behind the shear angle is sent into 300 tons of hydraulic presses and the concave, convex mould pull and stretch of exerting pressure, laid 2 μ m polypropylene films and make lubricant between mould and workpiece, the pull and stretch height H is 55-60mm, and the workpiece behind pull and stretch as shown in Figure 1;
(3) will send into 160 tons of punch presses through the workpiece behind the pull and stretch and cut peripheral edge portion, workpiece as shown in Figure 2;
(4) will send into to exert pressure in 160 tons of punch press shearing dies through the workpiece of shearing and cut into left and right sides two parts, die 3 is for being with bell-mouthed three sword mold cavities, intermediate slider 4 is located in the body of punch 5, the cut ends of workpiece 2 is corresponding with bell-mouthed three sword mold cavities of die 3, shearing die and shear history, as shown in Figure 6 and Figure 7.The stroke that moves up and down between punch 5 and the intermediate slider 4 is 1.8-3mm, and the workpiece shape through shearing as shown in Figure 3;
(5) will go out installing hole with 160 tons of punch presses respectively through the workpiece left and right sides spiral case behind the clip, the workpiece shape as shown in Figure 4;
(6) remove burr, in the welding of edge, mash welder upper edge, postwelding workpiece shape as shown in Figure 5.
(7) will carry out deburring, polishing, cleaning, check warehouse-in through the volute of blower of above-mentioned machine-shaping.
