Green brick forming equipment for environment-friendly bricks

Abstract

The invention discloses green brick forming equipment for environment-friendly bricks, which comprises a die and a stamping die body, and the die comprises an upper die and a lower die; the upper die is externally connected to a hydraulic lifting mechanism; and a punch forming assembly is arranged in the upper die and comprises a vibration base plate and a vibration excitation block, a roller is arranged on the upper portion of the vibration base plate and can move up and down, and a protruding block is arranged on the outer circle face of the roller. When the roller is in the working position, the distance between the upper surface of an arc groove and the axis of the roller is smaller than the sum of the height of the protruding block and the radius of the roller and larger than the radius of the roller. When the roller is in an idle position, the distance between the upper surface of the arc groove and the axis of the roller is larger than the sum of the height of the protruding block and the radius of the roller. According to the equipment, the friction force among blank particles can be reduced during green brick pressing, the flowability is improved, all faces of a pressed green brick product are consistent in density, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of brick adobe forming equipment, in particular to an environment-friendly brick adobe forming equipment. Background technique [0002] With the rapid development of my country's construction industry, there are various types of building bricks used to replace traditional sintered bricks, but mainly clay, coal ash, cement and other materials are used as raw materials to make slurry after adding auxiliary materials, and then the slurry It is shaped by bricks and can be used as a building material after curing. [0003] In the above-mentioned molding process, the pressing molding step of the brick has a greater impact on the quality of the finished brick, which directly affects the production efficiency, molding strength and appearance of the brick. The traditional brick forming equipment mainly uses a brick extruder to extrude the adobe, which squeezes the treated mud into a mud strip with a certain cross-section shape...

AI Technical Summary

Problems solved by technology

However, because traditional clay bricks will destroy land resources and cause environmental pollution, they can no longer meet the development needs of the new era.

With the tightening of environmental protection policies in recent years, unburned bricks using fly ash and construction waste as raw materials have begun to appear in China. When using traditional clay brick molding equipment to form unburned bricks, the appearance of the cut section is not beautiful, and Due to the lack of sintering process, the bricks formed in this way also have the defect of low strength, and are prone to cracks and collapse inside

[0004] Based on the above situation, there have also been some burn-free brick forming equipment through pressing. This kind of burn-free brick forming equipment mainly includes four-column hydraulic type and eccentric excitation type. Among them, the four-column hydraulic type adopts three-beam four-column frame The structure is used as the power of the upper mold, and the hydraulic system is used to control the downward pressure. When it is formed, it directly applies pressure to the surface of the slurry in the mold, and the friction between the blank particles of the slurry itself is relatively large, and the fluidity is poor. The contact surface of the upper and lower molds is dense and uneven, and even the defects of the corners appear, which affects the product quality; while the eccentric excitation type uses the exciting force generated by the vibrating table to vibrate the materials to be formed in the mold into bricks, which can effectively overcome The friction between the blank particles of the slurry itself is relatively large and the fluidity is poor, so that the density of the pressed brick products is consistent on all sides, and the quality of the product is improved. However, the defect is that it needs to wait for vibration after the entire brick is formed. The demoulding can only be carried out after the after-vibration elimination of the vibrating table, and due to the large inertia of the vibrating table, the process of eliminating the after-vibration of the vibrating table takes a long time, so that each time from the shutdown of the vibrating motor to the completion of the forming of the adobe It takes a lot of unnecessary waiting time to take out this process, which affects the production efficiency of the adobe. At the same time, the working noise and vibration generated by the equipment are very large, which easily causes the frame to be damaged by strong force.
