Method of manufacturing a rotary-type physical shield purifier

A method for manufacturing a rotary physical shielding purifier, characterized by, comprising the following steps:

• (1) placing spokes and an outer rim on a clamping die, wherein the clamping die has the following structure:
• comprising a clamping die body, a central hole disposed on the clamping die body, a plurality of spoke grooves disposed with the circle center of the central hole as a radiant point, and an outer rim groove disposed on the clamping die at a position far away from the central hole and in communication with the spoke grooves;
• respectively placing the outer rim, the spokes and a central clamp base in the outer rim groove, the spoke grooves and the central hole, ensuring that the outer rim contacts the spokes, and the inner ends of the spokes extend in the central hole;
• and pressing a pressing die on the spokes, ensuring that a section of the inner end of each spoke and the contact parts between the spokes and the outer rim are exposed outside the pressing die;
• alternatively, respectively placing the outer rim and the spokes in the outer rim groove and the spoke grooves, ensuring that the outer rim contacts the spokes, and the inner ends of the spokes extend in the central hole;
• pressing the pressing die on the spokes, ensuring that a section of the inner end of each spoke and the contact parts between the spokes and the outer rim are exposed outside the pressing die;
• and then placing the central clamp base in the central hole;
• (2) using a welder to weld the contact parts between the spokes and the outer rim;
• (3) installing a central clamp gland on the central clamp base, wherein the central clap gland fixes the inner ends of the spokes between the central clamp base and the central clamp gland via a clamping device;
• and
• (4) separating the pressing die from the clamping die, and taking the finished product out;
• wherein
• the central clamp gland is a recessed cambered cover;
• an axial sleeve hole is disposed in the center of the cambered cover;
• the circumference of the cambered cover forms into a pressing ring;
• when installing the central clamp gland on the central clamp base, the pressing ring is pressed on the spokes;
• when a pressure is applied on the cambered cover, a comparatively high pressure intensity can be formed between the pressing ring and the spokes because the contact area between the pressing ring and the spokes is small, such that the spokes are tightly fixed between the pressing ring and the central clamp base.
