1.1 Purpose:

The QT8-15D block forming machine developed and produced by our company is a special equipment for the production of building blocks. The machine can use fly ash, slag or other industrial waste residue and river sand, gravel, cement and other materials, through the replacement of mold production of a variety of different specifications of the hollow block, porous brick, curb stone, road brick and grass brick, ring tree brick, slope protection brick and other concrete products. The fabric-matching mechanism can also produce layered products.

1.2 structure

The main frame of the QT8-15D block forming machine adopts a gantry frame structure, which is strong and resistant to vibration and has good reliability. The design adopts the hydraulic discharge mode of independent foundation, and the raw materials are put immediately. Mesh wave type swing cloth structure, cloth effect is excellent. The plug-in welding mold is made of manganese steel carburizing and quenching. The 100000 mold is not easy to deform and wear. The QT8-15D block forming machine can form a simple production line with PLD1200 batching machine, JS500 mixer, 8 m belt conveyor and palletizer.

1.3 features:
1. This machine is a mechanical, hydraulic and computer automatic control comprehensive technical equipment, which is characterized by high efficiency, reasonable design, compact structure, simple operation and convenient maintenance;
2. The block forming is mainly mechanical vibration, supplemented by hydraulic pressure, and completed by vibration pressure. The compressive strength of the block products produced can reach more than 15MPa (MPa), with high compactness, good frost resistance and impermeability, excellent sound insulation, heat insulation and heat preservation performance, and accurate dimensions.
3, integrated oil system, high life, low energy consumption design.
4. Operation mode: It has different automatic and semi-automatic operation modes to ensure uninterrupted production.
5, variable frequency stepless speed regulation, to achieve a reasonable operating speed, accurate deceleration braking and positioning.
6, database system: intelligent services, can record, reset, save, file, warning, processing, print reports.
7, self-test function: failure can be automatically diagnosed to ensure production safety.
8, metering control system: high precision, fully automatic

QT8-15D type automatic hydraulic brick machine equipment

1. Plate feeder

consists of a pallet box, a plate-feeding fork, a fork frame, a propulsion cylinder, and a plate frame. It is mainly used to store pallets and transport pallets in cycles.

2, molding machine

is composed of main frame, distributing car, station shaft sliding sleeve, vibration table, mold, upper and lower synchronization mechanism, propulsion cylinder, etc. It is mainly used for main material filling, molding, vibration, molding, demoulding, etc.

3, block conveyor

is composed of transmission frame, chain transmission mechanism, belt pulley transmission mechanism, horizontal guide wheel and other parts, which is mainly used for conveying the finished block.

4. Hydraulic station

is composed of oil tank, motor, oil pump, filter, cooler, integrated block, hydraulic valve, etc., and mainly provides driving power source for various moving parts. Adoption of hydraulic stationN32 or N46 anti-wear hydraulic oil, the filtration accuracy of the oil injected into the oil tank shall not be less than 20μm, and the unfiltered oil shall not be injected into the oil tank.

5. Electrical control cabinet

(1) Control part

control part is composed of PLC programmable controller, expansion module, touch screen man-machine interface, intermediate relay, AC contactor and other electrical components. It has manual and automatic operation modes to control the action of each process. For example, the functions of pressing head up and down, die box up and down, main material car advance and retreat, pre-vibration, forming main vibration, demoulding, pallet advance and retreat, etc. can realize man-machine dialogue, and adjust the feeding times and vibration time outside the machine.
