Embodiment Construction

[0020] The invention relates to a hot pressing processing method of high-frequency multi-stage pressing.

[0021] The first step is to clean the mold and prepare materials, stack and press the materials into regular and compact entities, and clean up the residue on the mold.

[0022] The second step is to apply the release agent and heat the mold, heat the mold, and apply the release agent to the surface of the mold.

[0023] In the third step, the production line prepares multiple hot presses with different pressures. The pressure of the hot press gradually increases from the first to the last one, and the pressure of the last hot press is the same as that of the single hot press.

[0024] The fourth step is to send the heated mold into the production line and pass through the hot presses with different pressures in turn.

[0025] The fifth step is cooling and demoulding. The mold after the last hot press is cooled to 200°C through the pipeline, and the mold cooled to 200°C ...

Abstract

The invention provides a high-frequency multi-section pressurizing hot pressing processing method. The method comprises the following steps: 1, a mold is cleaned and materials are prepared, the materials are stacked, the stacked materials are pressed into a regular and compact entity, and residues on the mold are cleaned; 2, a release agent is applied and the mold is heated, namely the mold is heated, and the release agent is applied on the surface of the mold; 3, a plurality of hot presses with different pressures are prepared on the production line, the pressures of the hot presses are gradually increased from the first hot press to the last hot press, and the pressure of the last hot press is the same as the pressure of the hot press for single-time hot pressing; 4, the heated mold is fed into a production line and sequentially passes through hot presses with different pressures. 5, cooling and demolding are conducted, specifically, the mold passing through the last hot press is subjected to water cooling to 200 DEG C through a pipeline, and the mold cooled to 200 DEG C is subjected to demolding; and 6, machining forming is conducted, a demolded product is cleaned, and polishing is conducted after cleaning. The method has the advantage that the hot-pressing effect is improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a high-frequency multi-stage pressing hot-press processing method. Background technique [0002] The current mechanical hot-press processing is processed by a single high-pressure process, which not only takes a lot of time, but also requires extremely high requirements for the compression resistance of the mold and equipment, and once a single hot-press error occurs, it will Leading to the scrapping of the whole product, it is impossible to find out in time and stop processing. Contents of the invention [0003] The purpose of the present invention is to provide a multi-stage processing and high-frequency multi-stage pressurization processing method with high processing speed, which is especially suitable for rapid processing of large-volume products. [0004] The technical proposal of the present invention is: a hot press processing method with high-frequency multi-stage...
