Description

Technical Field

[0001] The present application relates to the technical field of metal container processing, and in particular to an automatic can body forming machine. Background Art

[0002] Metal cans are a common packaging container made of metal and are often used to store and transport a variety of products. They usually have a solid structure, good sealing and a long service life. Metal cans can be divided into round, square, special-shaped cans, etc. according to their shapes, or they can be divided into food can series, gift can series, chemical can series, etc. according to the use environment. Typically, metal cans with a circular cross-section are currently used to store aerosols.

[0003] In the manufacturing process of this kind of metal can, the can cover and the can body need to be produced separately and then assembled together to make it a complete metal can; specifically, in the manufacturing of the can body, the pre-prepared blank is usually a metal disc, and then the metal disc needs to be pressed, stretched, refined, tested and surface treated in sequence to obtain the finished product. Among them, in the pressing and stretching process, hydraulically driven punches are currently mainly used. The process of the metal disc being pressed by the punch is the process of the metal disc being stretched, and the hydraulic system is used to quickly complete the production of the can body.

[0004] In order to ensure that the metal can can store more aerosol and is lighter in weight, the current can body tends to be designed to be longer and thinner in thickness. When such a can body is produced using existing hydraulic punches, during the rapid stretching of the can body, as the can body becomes longer and longer, the wall thickness of the can body will change from large to small, while the stretching speed of the can body remains unchanged. The thinner can body may be torn under such rapid stretching, and the uncontrollable stretching speed may cause the product to be scrapped. In this regard, the producer hopes that the action of stretching the can body can be fast at first and then slow to prevent the above-mentioned tearing phenomenon as much as possible.

The installation box 323 is equipped with a second feeding rotation assembly 324, and the second feeding rotation assembly 324 is connected to a rotating disk 325, and the rotation axis of the rotating disk 325 deviates from the rotation axis of the installation box 323. The rotating disk 325 is eccentrically connected to a linkage arm 326, and one end of the linkage arm 326 away from the rotating disk 325 is rotatably connected to the sliding block 33.

[0039] The first rotating assembly 322 can drive the installation box 323 to rotate when working alone, thereby driving the sliding block 33 to move quickly through the linkage arm 326, while the second rotating assembly 324 can drive the rotating disk 325 to rotate when working alone, thereby driving the sliding block 33 to move slowly through the linkage arm 326.
