Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a blower housing, and more particularly to a method of manufacturing a blower housing. [Prior Art] According to the general blower casing, which is mainly made of many metal plates by riveting or locking, it is not only time-consuming to assemble, but also its structural strength is obviously insufficient. The more metal sheets are assembled, the higher the cost will be, and the assembly components must be consumed (such as locking and riveting components), which will increase the manufacturing cost and less. Economic benefits. Furthermore, since the general blower casing is made of a plurality of metal sheets, the metal sheets are likely to be vibrated when the blowers are actuated due to poor joint problems, and when the vibration frequency of each metal sheet and the Luyi fan When the frequency of the wind pressure generated during the operation resonates, the noise caused by the blower as a whole is much more increased. In view of this, how to improve the above disadvantages is the first lesson 4 of the present invention, and accordingly, the inventor of the present invention finally has the invention after continuous hard thinking and trial work.

Before the hydraulic forming shell step, a metal substrate is taken, and a cutting operation is performed on the 201116723 metal substrate, and the metal substrate is first opened to a predetermined size during the cutting operation. The air inlet, and then the cut metal substrate is placed in a hydraulic forming machine for oil forming, and the hydraulic forming machine maintains a predetermined molding time during mold clamping to make the metal base The material is indeed stretched into a first casing and a second casing having a predetermined size and corresponding to each other. In addition, the periphery of the partition is more bent to form a connecting portion, and the connecting portion of the partition is adapted to be in contact with the outer edge of the two shells, and is connected by a plurality of φ joints, and The two housings are joined together. Furthermore, after the step of hydraulically molding the casing, the present invention may form a recessed portion on each of the casings, and then apply a stamping process to the recessed portions of the casings to make the recessed portions. In the previous system, a first air inlet having a mesh shape is provided, and then a step of assembling the partition is performed. Alternatively, an assembly netting step may be performed after the step of assembling the separator, or an assembly netting step may be performed after the step of hydraulically forming the casing, and the assembly netting step is performed on the outside of the first air inlet of the casings. A protective net is installed separately. The above and other objects and advantages of the present invention are readily selected from the following detailed description of the embodiments of the invention. Of course, the invention may be varied on certain components, or in the arrangement of the components, but the selected embodiments are described in detail in the specification and their construction is shown in the drawings. [Embodiment] First, please refer to FIG. 1 and FIG. 2 together. The first embodiment of the method for manufacturing a blower casing of 201116723 according to the present invention includes the following steps: a. Hydraulic forming shell step : First, 'take a metal substrate separately' and apply a cut to the metal substrate and attach a predetermined size of the first air inlet to the metal substrate during the cutting operation. The cut metal substrate is placed in a hydraulic forming machine to form a jade, and the metal substrate can be uniformly squeezed by the extrusion molding action of the oil molding machine. The hydraulic forming machine is further configured to maintain a predetermined molding time so that the metal substrate can be surely extended into a predetermined size and corresponding to each other - the first housing 11 and the second housing 21, wherein The two casings 21 and 21 are relatively open-shaped, and the first air inlets 12, 22 and one air outlets 13, 23 are respectively formed on each of the casings i1, 2i. b. assembling the partitioning step: then taking a baffle-shaped "door" shaped partition 3 1 is installed between the two housings 1 1 , 2 1 between the opposite open sides, wherein the partition of the partition 3 Further, the connecting portion 3 2 is formed by bending, and the connecting portion 3 2 of the partition plate 3 1 is affixed to the outer edges of the two housings 1 1 and 2 1 and then worn by a plurality of connecting members 3 3 .
