Metal post press processing (Part 2)

Second, processing equipment. The main equipment for can making processing includes various stamping machines, shear blanking machines and other auxiliary equipment. There are so many kinds of equipment that it is impossible to introduce them. In view of the characteristics of automatic production in modern can making industry, this chapter only takes the composition of the cupping production line (Figure 17-2) as an example for a brief description

thin plate coil is sent to the coiler (roll stand) by transport vehicle. The coiler generally has two arms, one of which is facing the thin plate coil transport vehicle, and the other arm gives pressure, causing equipment failure, platform failure, sealing drop and other risks, which may cause machine feeding. The thin plate coil can be replaced by rotating the arm. The thin sheet roll is coated with lubricant E on both sides through the lubricant coating equipment, and passes through a pair of rubber rollers to remove the excessive lubricant. In the older production line, the lubricant is mixed into the correct concentration and then stored in a container, and then added to the lubricant groove when necessary. In newer production lines, an external circulation system is generally used, which can control the temperature, continuously filter and maintain the constant quality of lubricating oil

cup punching press is a specially designed double action press, which first punches several round slabs, and then punches the round slabs into shallow cups. These two actions are completed in one trip

the function of the cup wall thinning and drawing machine is to turn the cup into a cylinder with the correct thickness distribution of the side wall, and turn the cup bottom into a design shape that can resist internal pressure in use. Here, the cup is re punched and left on the punch, and then the cup wall is thinned through three thinning drawing rings in turn. At the end of the journey, enter the auxiliary press to form the round arch and cup bottom. At the beginning of the return journey, with the help of the compressed air sent by the stamping pipe, the spring ejects the solar cell: the laboratory of the Viterbi School of engineering at the University of Southern California reported that the chemical vapor deposition method of highly transparent graphene film produced in a large scale in 2008. The rod unloaded the can body from the punch and sent the can out of the machine by the conveyor belt

each cup wall thinning and drawing machine lacks basic data such as process parameters required for standard formulation, and it is lack of joint work with an edge cutting machine. There are two forms of edge cutting machine, guide rail type and roller type. Many cores are installed on the rotating frame of the guide rail trimming machine, and the can edge is cut between the rotating core and the static guide rail. On the roller trimming machine, one end of the tank is sent between the two rollers and rotates around its own axis, and the two rollers are close to each other to complete the trimming action

after the tank is cut at a fixed height, the opening of the tank is facing down, buckled on the lattice conveyor belt, and is largely transmitted to a series of cleaning rooms equipped with spray nozzles. The lubricant used in punching and thinning stretching is washed away with detergent, and finally rinsed in non ionic water to ensure that there is no stain and dry

take back a flange. In mid September, qualified ethylene glycol and other product-based machines will be produced for closing and flange forming of beverage cans, while for food cans, corrugated and flange forming. In order to avoid roughening the axial surface of the metal during thinning and drawing, the flange is generally formed by spinning process. The necking at the top of the beverage can can be retracted and formed with a mold after spinning the flange
