Bidirectional pressing-vibrating type building block shaping machine

Abstract

A bidirectional vibration block-forming machine belongs to a forming equipment of a building block or a brick. A molding box (1) is a framework cutting through from top to bottom; an outer framework of the molding box (1) is arranged on four columns (17) of a machine frame (10); a lower pressure head (3) is correspondingly arranged under the molding box (1) while an upper pressure head (2) is arranged above the molding box (1); the lower pressure head (3) is connected with a cylinder (11) of the lower pressure head through a lower excitation mechanism while the upper pressure head (2) is connected with a cylinder (9) of the upper pressure head. The molding box (1) adopts the suspension arrangement, which can greatly reduce the frictional resistance, add the density and overall strength, reduce the formulation ratio of cement gelling raw materials and the manufacture cost and improve the vibration efficiency with lower vibration force, and can be made into bricks or brick products with multi-row, be convenient for material-saving and thermal insulation with a high hollow ratio, improve the grade of the wall materials and create beneficial conditions for the development of heat-preservation and heat-insulation products.

Description

technical field [0001] The invention relates to a building block or brick forming equipment, in particular to a two-way pressure vibration type block forming machine. Background technique [0002] The block forming machines used in the current market are all unidirectional compression molding. Chinese Patent Publication No.: CN1234322, Publication Date: November 10, 1999, the name of the invention is "Blind Hole Type Porous Block Automatic Press", which proposes a pressurized, one-way The technical scheme of compound vibration and plastic extrusion molding, it can use sand, fly ash, slag, loess, cement, etc. to produce non-fired porous blocks, and can also produce sintered porous blocks with inferior clay. It has a simple structure and reliable operation. Its products have high strength and high hollow rate. [0003] Chinese patent announcement number: CN 2275028Y, date of announcement: February 25, 1998, utility model name "Hollow block two-way forming machine", proposed ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defects and deficiencies of the existing block forming equipment, such as high power and energy consumption, uneven pressure, and inconsistent strength of various parts of the block products, and provide a low pressure vibration force and uniform block forming strength. High density, can make multi-row hole hollow blocks or bricks, high hollow rate, save raw materials bi-directional pressure vibration block forming machine
