Manufacturing method of vacuum insulation panel and special punching equipment used

Abstract

The invention discloses a vacuum thermal insulated panel and a manufacturing method thereof and special punching equipment adopted in the manufacturing method. At least one penetrating hole is formed in a powder plate of the vacuum thermal insulated panel. A barrier film is wrapped on the outside surface of a powder plate solid structure in a sealing mode, and anchor holes which are in one-to-one correspondence to the penetrating holes in the powder plate are formed. The manufacturing method includes the steps that forming of the powder plate, punching of the powder plate, vacuum wrapping of the barrier film and punching of the anchor holes, wherein the special punching equipment adopted in the step of punching of the powder plate comprises an upper template, a lower template, a tubular die head, an inner pressing plate, an outer pressing plate and a drive unit. The drive unit drives the upper template to move longitudinally. The tubular die head is fixedly arranged below the upper template. The inner pressing plate and the outer pressing plate are located on the inner side and the outer side of the tubular die head respectively and are elastically arranged below the upper template. The lower portion of the tubular die head and the upper side of the lower template are provided with tool edges matched with each other in a corresponding mode. Through the vacuum thermal insulated panel, construction waste is reduced, riveting strength is increased, construction cost is saved, and construction efficiency is improved.

Description

technical field [0001] The invention relates to a vacuum insulation panel made of gas-phase silica powder and microsilica powder as core materials, in particular to a vacuum insulation panel which is convenient for anchoring, a manufacturing method thereof and special equipment for punching holes. Background technique [0002] The current vacuum insulation panels are basically made by vacuum-sealing a powder panel with an air-tight barrier film. When the vacuum insulation panel is anchored to the wall, it generally adopts the method of first folding the edge and then folding the corner to leave a hole for drilling and anchoring. The method is to anchor around the vacuum insulation panel. This anchoring method is likely to cause damage to the vacuum insulation bag during drilling, resulting in air leakage, resulting in waste in the construction process, and there are many anchor points, and the anchoring cost is high. This time, the production cost is high and the production ...
