Modeling and Temperature Control System Design of Heating Furnace for Thermoforming Machine

摘要

The temperature control of the heating furnace has a great influence on the quality of the product. Too high temperature or too low will make the product disqualified. Based on a company's thermoforming machine, this paper analyzes the function of the heating system of the thermoforming machine in the whole equipment, as well as its structure, design principle, heating mode and so on. For the characteristics of the temperature field of the heating system of the thermoforming machine, the heat rise curve of the sheet is obtained by the heating simulation experiment of the sheet. The temperature control system suitable for sheet metal heating is developed. The experimental results show that the scheme can meet the specific requirements of the process, the temperature control is accurate, the reaction is sensitive, and the expected purpose is achieved.
