A kind of alloy easy-open lid forming method

Abstract

The invention discloses a method for forming an alloy easy-open lid, which comprises the following steps: 1. coil wave shearing; 2. printing and coating processing; 3. basic lid forming; 4. forming lid forming; By setting the plate fixing device, the generation of scratches caused by the poor fixing when the plate is punched is reduced. After the plate body is in contact with the plate, along with the falling of the end of the upper clamping plate, the adjusting plate can adjust the position of the plate body until the first tooth plate and the second tooth plate are tightly connected. This reduces the problem of sheet scuffing at the end of the movement of the upper clamping plate. The cover airbag forms a plate-like cover structure under the action of air pressure. As the tank cover moves forward, the cover cover airbag is bent, and the air of the cover cover airbag is squeezed out. When the cylindrical can lid is taken away by a worker or a manipulator, the cover airbag is filled with air in the airway, and the cover airbag is inflated and returns to the initial state. The recovery of the airbag mainly relies on the driving of the air in the airway, thus avoiding the problem of elastic failure of the rubber.

Description

technical field [0001] The invention relates to the field of easy-opening covers, in particular to a method for forming an alloy easy-opening cover. Background technique [0002] Tinplate easy-open lids were first used in metal canned food packaging in 1973. Compared with aluminum easy-open lids, tinplate easy-open lids have better corrosion resistance, easy recycling, and low cost. Therefore, they are widely used in canned food packaging. has developed rapidly. my country's tinplate easy-open lid started relatively late. In the late 1980s, the tinplate easy-open lid produced with domestic equipment and technology began to be applied to cans of eight-treasure porridge, which truly broke through the problem of "canned food is delicious and difficult to open". After years of hard work, the production capacity and quality of domestic tinplate easy-open lids have been rapidly improved, replacing imports and starting export. In the process of making the cover of the existing ti...

Problems solved by technology

In the process of making the cover of the existing tinplate, it is necessary to use the tinplate fixing device to fix the tinplate plate, so that the tinplate can be efficiently and accurately loaded into the crank press for pressing. The existing tinplate fixing device has a complex structure and troublesome operation. It is difficult to firmly clamp and fix the tinplate during use, so that the tinplate often falls off or deviates during the processing and making of the cover, which affects the processing efficiency and quality of the tinplate and reduces the economic benefit, and the existing tinplate fixing device is difficult to fix a variety of The size and specification of tinplate has a narrow scope of application, and it is difficult to meet the needs of production and use.

CN104985070A discloses a tinplate clamping device fixed by a clamping cylinder, but as the upper clamping plate rotates and falls, the end of the upper clamping plate also moves in the horizontal direction, so it is easy to form scratches on the plate

During the lid collection process, the rear end of the lid collection groove of the can lid (the end of the lid entry) often has a pushing device or a hand that pushes the can lid away, while the front end (the end of the lid exit) is often in a free state due to limited conditions. This causes the can lid to fall forward easily at the front end, which is prone to scratches on the can lid, resulting in the occurrence of arched lids or jammed lids.

Most of the existing cover collecting devices use the elastic force of springs or rubber strips to achieve recovery. After a long time of use, the elastic performance decreases, causing the cover blocking device to fail
