Problems solved by technology
At present, many ice buckets on the market are manufactured by welding process: first, the metal sheet is surrounded into a cylindrical shape, and then the two opposite sides of the sheet are butt-welded to form a bucket wall, and then a piece is welded at the bottom of the bucket wall. bottom plate, thus forming a cylindrical ice bucket, the work efficiency of the above-mentioned welding process is low and cannot meet the production needs, and the ice bucket manufactured by the welding process not only has a poor appearance, but also the welding is not smooth, not easy to clean, and easy to hide dirt Nurgle and Corrupted

Embodiment Construction
[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0028] In this embodiment, the blank used is a 304 stainless steel sheet with a thickness of 1mm and a diameter of 405mm, and the final product 10 of stretch forming is an ice cream with a barrel mouth diameter D of 206mm, a barrel body height H of 205mm, and a barrel bottom diameter d of 130mm. Bucket, its stretching steps are as follows:
[0029] (1) Stretching for the first time: Stretch the 304 stainless steel sheet with the first drawing die to obtain the first semi-finished product 2 with the mouth of the barrel facing down and the bottom of the barrel facing up, such as figure 2 As shown, the barrel height H of the first semi-finished product 2 1 It is 0.732 times of the barrel height H of the final product 10, namely H 1 =0.732H=150mm, the first semi-finished product 2 includes: from the barrel mouth to th...

Abstract
The invention discloses a drawing molding process for an ice bucket. The drawing molding process comprises the following steps that 1, a stainless steel sheet is drawn into a first semi-finished product formed by successively connecting a first cylindrical part, a first circular truncated cone part and a first bucket bottom part; 2, the first semi-finished product is drawn into a second semi-finished product formed by successively connecting a second cylindrical part and a second bucket bottom part; 3, the second semi-finished product is drawn into a third semi-finished product formed by successively connecting a third cylindrical part, a first inverted circular truncated cone part, a fourth cylindrical part and a third bucket bottom part; 4, the third semi-finished product is drawn into a fourth semi-finished product formed by successively connecting a fifth cylindrical part, a second inverted circular truncated cone part and a fourth bucket bottom part; and 5, the fourth semi-finished product is drawn into a final finished product in the second circular truncated cone shape. By means of the drawing process, the whole stainless steel sheet can be drawn into the ice bucket, the quality of the ice bucket is improved, the surface of the bucket wall is kept smooth and level, and clean-keeping and cleaning are facilitated; and the production efficiency of the ice bucket is improved as well.
Description
technical field [0001] The invention relates to a machining process for making an ice bucket. Background technique [0002] An ice bucket is a relatively common container for holding ice cubes. At present, many ice buckets on the market are manufactured by welding process: first, the metal sheet is surrounded into a cylindrical shape, and then the two opposite sides of the sheet are butt-welded to form a bucket wall, and then a piece is welded at the bottom of the bucket wall. bottom plate, thus forming a cylindrical ice bucket, the work efficiency of the above-mentioned welding process is low and cannot meet the production needs, and the ice bucket manufactured by the welding process not only has a poor appearance, but also the welding is not smooth, not easy to clean, and easy to hide dirt Nurgle and be corrupted. Contents of the invention [0003] The invention provides an ice bucket stretching forming process capable of stretching a stainless steel sheet into an ice ...
