Problems solved by technology

[0002] There are two types of flanging products: hot flanging and cold flanging. The traditional heating method of hot flanging is resistance wire heating or electric furnace heating. The heat conduction heating method has low heating efficiency, short service life, and high production site temperature during heating. , long warm-up time and other disadvantages

Abstract

An electromagnetic heating flanging mold comprises a mold body, glass fiber cotton, a fiber hard plate and high-temperature-resistant electric wires. The mold body is divided into an upper mold on theupper portion and a lower mold on the lower portion. The outer side of the mold body is wrapped by the glass fiber cotton achieving a thermal insulation effect. The heat-resistant fiber hard plate achieving a supporting effect is arranged outside the glass fiber cotton. A high-temperature-resistant electric wire coil is wound in the fiber hard plate. The high-temperature-resistant electric wiresare wound on the upper mold and the lower mold correspondingly. The high-temperature-resistant electric wire wound on the upper mold and the high-temperature-resistant electric wire wound on the lowermold are connected to a power supply after being connected in series. Two temperature sensors are arranged on the periphery of the face, connected with the upper mold in a butt joint manner, of the lower mold. The two temperature sensors are connected to a temperature controller outside the mold body. The problem that due to the adoption of resistance type heating of electric heating sheets, electric heating coils and the like and the adoption of the heat conduction type heating, the thermal efficiency is low is fundamentally solved through the manner of electromagnetic heating, product self-heating and direct heating with the high thermal conversion efficiency capable of reaching up to 95%

Description

technical field [0001] The invention relates to a mold, in particular to an electromagnetic heating flanging mold. Background technique [0002] There are two types of flanging products: hot flanging and cold flanging. The traditional heating method of hot flanging is resistance wire heating or electric furnace heating. The heat conduction heating method has low heating efficiency, short service life, and high production site temperature during heating. , long warm-up time and other shortcomings. Contents of the invention [0003] In order to solve the above problems, the present invention provides an electromagnetic heating flanging mold with controllable heating temperature and high thermal efficiency. [0004] The technical scheme that the present invention takes: [0005] An electromagnetic heating flanging mold, including a mold body, glass fiber cotton, fiber hard board and high temperature resistant wires, the mold body is divided into an upper mold and a lower mo...
