Suction cone manufacturing system for blower {A SUCTION CONE MANUFACTURING SYSTEM FOR BLOWER}

The present invention relates to a suction cone manufacturing system for a blower, and more particularly, to a suction cone manufacturing system for a blower that can manufacture a suction cone for guiding the movement of the fluid sucked into the blowing fan.

In general, factories and various industrial sites discharge air or dust in closed areas to the outside, and in order to prevent gas poisoning in a work environment where a lot of harmful gases are generated, or to reduce the temperature of the work environment, a large amount of air is used. High-capacity industrial blowers that can circulate quickly are widely used.

Since industrial blowers require different blower capacities according to the size and size of a factory or a workroom, they need to be made to order rather than to produce and sell to a certain standard, and then calculate the required blower capacity. Most of the industrial blowers are manufactured by combining bolting or welding by manufacturing base frames, impeller cases, suction cones, etc. that support them when the motor capacity and the fan size are determined. .

In particular, the suction cone is to be installed on the suction port side of the impeller case to minimize the turbulence of the air, to be manufactured in a set standard corresponding to the above-described configuration, such as the prior art related to the manufacturing apparatus of the suction cone in Japan Korean Laid-Open Patent Publication No. 58202927 (Nov. 26, 1983) discloses a method for manufacturing a warehouse suction cone. In the manufacturing apparatus according to the prior art, as shown in FIG. 1, after the plate 7 is fixed between the mandrel 8 and the platen 10, the forming roll 12 supported by the holder 13 is fixed. It forms a structure that applies the pressure (P) in the axial direction through. Through this, a conical body can be formed from the flat plate 7.

However, the conventional manufacturing apparatus rotates the flat plate as it is fixed to one side of the mandrel through the pressing force of the simple platen during the process for forming the cone body. In this case, the plate rotates at a high speed together with the mandrel and the platen. At this time, since a separate supporting means for supporting the plate is not disclosed, the plate moves in an unspecified direction due to the rotational force generated above the pressing force of the platen. Accordingly, there was a problem that an unbalanced cone was formed. That is, as the defective rate of the product increases, there is a problem that the efficiency of productivity is lowered.

In the conventional manufacturing apparatus, during the process of forming the conical body, the forming roll is pressurized from one side of the plate to the circumference of the plate, and the portion of the plate is gradually brought into close contact with the mandrel. Mold to achieve. At this time, the flat plate is gradually formed along the outer shape of the mandrel through contact with the forming roll, but the end circumferential portion having a relatively lower stress than the inner side of the thin plate is rolled up in the forming roll direction rather than the outer part of the mandrel. As a result, there was a problem that it is difficult to be molded into the shape of the conical body corresponding to the shape of the mandrel.

Here, since the conventional manufacturing apparatus does not disclose any configuration for preventing the circumference of the end portion of the flat plate as described above, such a phenomenon as described above occurs repeatedly on a portion of the flat plate. There was a problem that the defect of the molded product is frequently generated, such as deformation or breakage of a portion of the phenomenon occurs.

In the conventional manufacturing apparatus, after forming a flat plate in a shape corresponding to the outer shape of the mandrel, a part of the flat plate is cut by using a bite provided separately in FIG. 1 (b). Complete the conical body of the form penetrated as shown in. In this process, in order to cut a portion of the molded plate, there was a need to separate the molded plate from the mandrel and place it back into a separately prepared bite.
