Shape follow-up compacting method for thermal-insulation pad

Abstract

The invention discloses a shape follow-up compacting method for a thermal-insulation pad. The shape follow-up compacting method comprises the following work steps: sheets, respectively cutting a plurality of layers of materials into the specified dimension of sheets; material die cutting, utilizing a corresponding cutting die to cut the sheets into follow-up shapes, and in die cutting, reserving the allowance at the peripheries of the sheets; boundary material reuse, recycling and reprocessing the boundary materials generated in the step 1 and the step 2; paving materials, paving the materialsgenerated in the step 1, the step 2 and the step 3 layer by layer according to layers; step 5, mould pressing, putting the material in the step 4 into a mould to be compacted; step 6, trimming, performing trimming treatment on a product generated in the step 5. By means of statistics in a production process and the manufacturing technology disclosed by the invention, solid waste can be reduced by30% to 60%, 100 percent utilization on glass wool is achieved, raw material cost can be saved by 20 to 30% after the raw materials are reused, energy is saved to the maximum extent, consumption is reduced to the maximum extend, and a lot of material cost and solid waste treatment cost can be saved for enterprises.

Description

technical field [0001] The invention relates to a conformal pressing method of a heat insulating mat, in particular to a conformal molding manufacturing process of a heat insulating mat capable of reducing product materials and leftover materials, saving energy and reducing consumption. Background technique [0002] Vehicle interior fiber materials have a large number of structural parts, connecting parts, and protective parts with three-dimensional shapes, which need to be pressed into molds. When preparing materials, the size of the materials is generally determined according to the longest and widest shapes. The materials are based on It is mainly rectangular. When the product is pressed, the edge material has been solidified by hot pressing, so it can only be treated as garbage and solid waste separately. With the increasingly severe environmental protection situation, the amount of solid waste must be strictly controlled to the minimum. Therefore, the design of a The pr...
