Embodiment 1

[0020]Carbon steel plates with a thickness of 10mm are used to make 8 templates 3 with a frame. The thickness of the frame is 24mm. The edges of the two are aligned and spot welded into a whole. A number of circular holes with a diameter of 38 mm and a depth of 30 mm are drilled on the center line in the length direction, and a cylinder with a diameter of 16 mm is welded on the lower surface of the template corresponding to the circular hole position, forming the upper and lower templates 3. The cylinder and the circular hole can be inserted fit the structure, then the length H o The compression spring 13 with a stiffness K of 80mm and a stiffness K of 130N / mm is assembled in the cylinders and round holes corresponding to the adjacent upper and lower templates 3, starting from the gap between the first template 3 and the second template 3 on the uppermost layer , select the number of compression springs 13 in turn: 4, 8, 16, 32, 64, 128, 256, so that the gap distance between t...

Embodiment 2

[0023] The template 3 of this example shares 3 pieces, and the height of the mold frame is 35cm, and the width is 3cm, and the bottom of the mold frame is a bolt fastening structure with the template 3; The number of compression springs between them is 12 and 18 respectively from top to bottom, so that the gap distance between the three-layer formwork is kept at about 100mm; two vibrators 12 are installed at the bottom of the vacuum box 1, and the distance between them is 60mm. ° electrical angle for flow control to generate a frequency of 50Hz.

[0024] In this example, Dunhuang jade from Guazhou, Gansu and hibiscus stone from Inner Mongolia are used to form a closely stacked block body. The particle size of the stone is 2-15cm; the mixture used to fill the gap is resin with a mass ratio of 10%. , 22% aluminum hydroxide powder and transparent stone particles with a particle size of 1-10mm are mixed together to form a viscous material body; the stones are arranged in two layer...

Embodiment 3

[0026] Basically the same as embodiment 1, the difference is: template 3 shares 6 pieces, and the number of compression springs between each template is 8, and the installation method of compression spring 13 is the same as embodiment 1; The template 3 on the upper layer is lifted and compressed at a lower frequency of 0.02 Hz; the vibrator 12 installed at the bottom of the vacuum box is 4 hydraulic exciters, and the plug rod of the exciter passes through the bottom plate of the vacuum box 1 and pushes to On both sides of the lowermost template 3, the template 3 is vibrated at a vibration frequency of 150 Hz. In this example, agate and crystal saws are used to closely splice the cracked broken boards with a gap width of 1-3mm. The matrix is ​​made of 20% by mass polyester resin liquid, aluminum hydroxide powder and crystal sand. Sticky material, made of siliceous jade thin plate whose surface layer is artistically spliced, and the substrate and siliceous jade gap are light-tra...

Abstract

The invention relates to a multilayer combined type vacuum stone molding device which solves the problems that the traditional stone molding device only can mold stones piece by piece, the solidification is carried out in addition, molded composite boards are uncompacted, are easy to buckle and deform, and the like. The device is characterized in that an oil cylinder or an air cylinder with a hold-down device are arranged on the top of a vacuum tank; a supporting spring and 2 to 6 vibrators with 50-300Hz of frequency are arranged at the bottom of the vacuum tank; a plurality of layers of mold boards which are arranged in a stacked manner are also arranged in the vacuum tank; and a plurality of compression springs are arranged among each layer of the mold boards. The excitation force generated from the lower parts of the vibrators and the low-frequency excitation force generated from the upper part of the vacuum tank are matched with the compression springs among the mold boars and the supporting spring at the bottom of the vacuum tank to jointly form a vibration process of amplitude variation thereof, and the molding and the solidification are integrally carried out, thereby improving the working efficiency and restricting the problem that the composite boards buckle and deform in the solidification process. The multilayer combined type vacuum stone molding device is suitable for vacuum glue permeation of minerals such as quartz jade material and the like and the molding of spliced composite boards.

Description

technical field [0001] The invention relates to the field of stone and artificial synthetic stone forming devices, in particular to a multi-layer combined vacuum stone forming device. Background technique [0002] The current production process of natural stone used as building decoration is to use two main processes of sawing and grinding to make boards for blocks with less cracks, and for the crushed stones to be further crushed by stirring and vacuum vibration. The main process is forming, and then sawing and grinding processes to make composite panels. With the large-scale development of Gansu Dunhuang jade, Inner Mongolia hibiscus and Shanxi obsidian, the problem of how to transform and utilize these minerals with high hardness and severe cracks actually poses a challenge to stone processing technology, which may also form a kind of It is called "jade building materials" industry. Among them, the artificial quartz stone is a resin-based mixture, using a pressure tool ...
