Invention name multi-roller and multiple winding method
The invention relates to a method for multi-rolling the edge of the top or bottom cover of the barrel with the edge of the barrel of the barrel and a multi-rolling method. The method is to pre-process a part of the width of the barrel flange required for the multiple roll seal, and the remaining part is processed in the initial stage of the roll seal, and the flange of the barrel body is covered by the top or bottom cover of the barrel by the sealing roller. Flange multiple seals. The shrinking machine is provided with a sealing roller and a movement control means. The sealing roller has a flat portion that supports the flange and is substantially parallel to the top or bottom cover and a curved portion for sealing that is attached thereto. The movement control means is for controlling the moving means of the support member and the moving means of the sealing roller.

Multi-winder and multi-sealing method using expanded chuck
SUMMARY OF THE INVENTION The present invention relates to a multiple crimper and a multiple crimping method using an expansion chuck. In the present invention, the bead-engaging roller b which is moved toward the center of the bottom cover by the rotation edge of the edge of the bucket is multi-sealed by the cover-curling curved surface and pressed by the cone The profiled surface presses the portion connected to the multiple winding portion on the supporting tapered surface of the expansion chuck, so that the multiple winding portion is formed into the indented curl inner edge state, and more barrels can be sequentially disposed to save Storage space to improve handling efficiency. The winder of the present invention includes a crimping roller, a fixed chuck, an expansion chuck, and the like.

Utility model name thin plate barrel precision reeling machine
Abstract This reeling machine is a machine that can accurately roll a thin plate into a cylindrical or truncated cone. It consists of a cylindrical or truncated cone shaped fixed die with a round or conical roll combination that can be rotated around the forming die. After the thin plate is fixed on the molding die by the pressing plate, the pressing roller is pushed and formed along the forming die, and the thin plates are welded on both sides of the molding die. After the weld is flattened and then pressed and pressed several times, the barrel body and the molding die have the same curvature, so that the thin plate body with more accurate size and roundness can be obtained. The rounding machine has a simple structure, low cost, convenient operation, and high shape and dimensional precision of the product.
