Film mulching device for metal inner wall and film mulching method

Abstract

The invention discloses a metal inner wall laminating device, which comprises a power supply, wherein the power supply is an alternating current, a coil electrically connected with the power supply through a conductor, a cooling device arranged on the axial or radial side of the coil, a mulching film and a deformable film mulching module. The mulching method of the metal inner wall mulching deviceincludes the following steps: step one: changing the shape of the film mulching module to match the shape of the metal cavity; step two: covering or rolling the covering film on the surface of the film mulching module; step three: filling the film mulching module into the metal cavity, placing the metal to be coated through the enclosed space formed by the coil, and placing the film mulching module in the middle of the coil; step four: turning on the alternating current, starting the device and heating the metal; step five: starting the cooling device, cooling and taking out the film mulchingmodule. The inner wall of the metal can be conveniently and rapidly coated with the adoption of the film mulching device.

Description

technical field [0001] The invention relates to the field of film covering, in particular to a metal inner wall film covering device and a film covering method using the device. Background technique [0002] For some metal products, it is usually necessary to coat the surface, or as an insulating layer, or to protect the metal surface. The commonly used coating methods include spray coating, etc., but this method is used to coat the surface of the plate The membrane is simple and convenient, but it cannot be well coated for the inner wall of the tube. For the irregular shape of the inner wall, it is more difficult to adopt the traditional film covering, the process is difficult, and it cannot guarantee full coverage. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a metal inner wall coating device. [0004] In order to achieve the above object, a technical solution adopted by the present invention is: a metal inne...
