The scope of the patent application:
l, metal container with the following characteristics:
The utility model is composed of a cylindrical shape and a basin top and a bottom cover fixed at both ends thereof, wherein both end portions of the barrel body have a barrel flange formed by bending at a right angle to the cylindrical shaft, and the peripheral portions of the top and bottom have a top and bottom flange formed along the flange of the barrel and protruding outwardly from the barrel flange. The barrel flange coincides with the top and bottom flanges, and the top and bottom are embedded in the end of the barrel. The barrel flange is crimped to the top and bottom flanges to form a triple seam. In the container in which the triple stitching is formed, the cross-sectional shape of the top and bottom of the stitching portion is almost semi-elliptical or semi-circular as a whole, and the outer side of the top and bottom faces outward in an arc shape, and the middle portion of the top and bottom portions is substantially perpendicular to the axis of the container. Parallel, the barrel flange is pressed tightly against the top and bottom flanges, the metal contacts each other, the center flanges of the seam are coincident, and the gap between the flange tip of one flange and the curved portion of the other method is filled with filler. A metal container having the above features is sealed.
2. The metal container according to claim 1, wherein the outer side of the top portion and the outer portion of the curling joint project outward in an arc shape.
3. A method of manufacturing a metal container, characterized in that: the two ends of the cylindrical barrel are bent outwardly at an angle to the barrel axis to form a barrel flange, and the peripheral portion of the top and bottom of the bowl are along the barrel. The flange of the body flange and the flange of the barrel are more outwardly curved to form the top and bottom flanges, and the flange of the barrel is heavy with the top and bottom flanges, so that the top and bottom are embedded in the end of the barrel, and will have a circle The crimping joint clamping device of the molding surface is embedded in the top and bottom, and the top and bottom of the barrel are connected by the crimping joint clamping device through the seaming joint clamping device. While rotating the side seam clamping device described above, the curling roller having the forming groove extending along the circle and the end bending pressing roller are sequentially arranged toward the forming surface of the seaming seaming device Press down to form a triple crimped seam from the barrel flange and the top and bottom flanges described above on the forming groove, and then shaped to form a crimping joint at the seaming portion. In the method, the end portion of the forming groove of the forming groove of the integral bending roller and the tip end of the bottom flange are bent at the end, and the crimping roller is used. The forming groove performs a seaming of the barrel body and the top and bottom cover method, and after the crimping is completed, the forming groove of the integral pressing roll is bent by the front end portion to form a curling joint portion of a predetermined shape.
4. A manufacturing apparatus for a metal container, characterized in that both ends of the cylindrical barrel are respectively embedded with a basin-shaped bottom cover; and will be a seamed seam having a cylindrical molding surface driven by rotation Clamping device; the integrated barrel body is positioned with the top and bottom; the side seam clamping device is respectively provided with an opening, and the crimping roller and the end bending shaping roller which are provided with the forming groove in the circumferential direction are connected to the crimping edge The clamping clamping is freely movable: a crimping clamping device supported by a rotating shaft and an end-curved integral pressing roller, and a seam-clamping device that extends in a straight direction with respect to the cylinder axis The flange forms a triple seam with the top flange flange described above, and in such a setting, the first point (human side) of the end bending forming roller is provided with a concave portion for end bending. .
5. The apparatus for manufacturing a gold container according to the fourth aspect of the invention, characterized in that the first point (inlet side) and the first point (out side) of the end bending forming roller are respectively provided with a concave portion. .
Detailed description of the invention:
The present invention relates to a metal container, in particular, a cylindrical metal container having a large amount such as a steel barrel which is fixed at both ends of the cylindrical body by a seam between the top and the bottom, and a manufacturing thereof, and a manufacturing thereof Method and apparatus.
Below, the steel barrel is taken as an example for explanation:
