Pot bottom multi-layer pressing production process and production device thereof

Abstract

The invention provides a pot bottom multi-layer pressing production process which comprises the following processing steps of: 1, stretching a steel metal plate to form a pot body, inverting the pot body, and enabling the pot bottom to face upwards; 2, heating a metal net to 1100-1400 DEG C, and then placing the metal net on the pot bottom; 3, jointly heating the metal net and the pot bottom to allow the temperature of the metal net to reach 1400-1600 DEG C, and pressing the heated metal net and the heated pot bottom together through a pressing head on the upper portion; 4, stopping heating, placing an aluminum plate on the metal net, and continuously pressing the aluminum plate on the pot bottom through the pressing head; and 5, cooling the pot body and taking out the pot body. Accordingto the technology, the metal net is heated to be pressed to the pot bottom, meanwhile, waste heat is used for melting and pressing the aluminum plate, and the overall shape of the pot bottom after being attached is guaranteed. And more contact surfaces are formed between the aluminum plate and the pot body, so that the aluminum plate and the pot body are attached more tightly.

Description

technical field [0001] The invention relates to the technical field of pot processing, in particular to a multi-layer lamination production process and a production device for a pot bottom. Background technique [0002] Pots are usually used for cooking food, so in order to use iron or stainless steel as the inner layer, in order to ensure the thermal conductivity of the pot body, it is necessary to wrap the aluminum layer inside the pot body, so that the overall thermal conductivity of the pot body good. The traditional processing technology usually directly attaches the aluminum layer to the bottom of the pot body, and uses sheet materials for bonding, so that the bonding area between the steel layer and the aluminum layer inside the pot body is small, and separation is easy to occur The interlayer phenomenon causes the thermal conductivity of the pot body to deteriorate. In the traditional bonding process of steel layer and aluminum layer, the bonding position needs to ...

Problems solved by technology

The traditional processing technology usually directly attaches the aluminum layer to the bottom of the pot body, and uses sheet materials for bonding, so that the bonding area between the steel layer and the aluminum layer inside the pot body is small, and separation is easy to occur Interlayer phenomenon, resulting in poor thermal conductivity of the pot

In the traditional bonding process of steel layer and aluminum layer, it is necessary to heat the bonding position at the same time, but due to the large difference between the melting point of steel and aluminum, it is difficult to control the temperature, making the bonding process more difficult

The traditional bonding process of stainless steel pot bottom is to heat the bottom of the pot and the aluminum plate to be bonded at the same time, and then bond the two plates together. This method usually needs to be carried out at a high temperature as a whole. Slowly compress the aluminum plate material and the bottom of the stainless steel pot, so that the pressing time is longer, and the state of high temperature needs to be maintained for a longer time, which consumes more energy. At the same time, the direct bonding between the two planes also makes the bonding position not tight enough
