QT18-15 Automatic Block Making Machine
Maxport QT18-15 machine advantages are as follows:
1. Advanced technology and a robust, stable design make the machine 10-20% heavier than similar models, resulting in significant vibration absorption.
2. The machine body is constructed of thick-walled square tubes and extra-long guide sleeves, ensuring a sturdy and shock-resistant structure and precise pressure head movement.
3. A low center of gravity design with the vibration table 600mm above the ground ensures that 90% of aftershocks are directed to the ground, extending the equipment's service life.
4. Excellent synchronization. The pressure head and demolding frame are both equipped with adjustable synchronized swing arms, ensuring that the pressure head and demolding tolerances are within +/-1mm.
5. Vibration and pressure separation technology, equipped with a vibration support plate and auxiliary pressure head with shock-absorbing rubber pads, completely isolates vibration and pressure interference.

Vibration System
The six-axis vibration box provides a high and powerful excitation force of 205 kN, with an amplitude of 2 mm and an acceleration of 15 g. This allows for rapid material formation in approximately 2 seconds, fully liquefying the cement and increasing strength by one level under standard weight mix conditions.
Inovance Servo Motors utilize four 12 kW servo motors, offering excellent shaft synchronization, fast start-up speed, high vibration frequency, and rapid forming speed. The servo motors operate at high speed during vibration and at low standby speed during inactivity, saving approximately 10-20% in energy savings.
The vibration platform utilizes a dynamic and static combination, ensuring consistent flatness of the support plate under lower mold pressure and preventing uneven block heights due to inconsistent compression ratios of the damping blocks.
The high-quality polyurethane damping blocks, with their optimal hardness design, position, and structural layout, are both durable and reliable, and they work optimally with the vibration platform and box to generate optimal excitation force.
Aggregate and Fabric Feeding System
The aggregate feeding box features a swing-arm feeding gear structure and a claw-type forced feeding mechanism, completely solving the feeding problem for thin-walled products (less than 20mm thick). The feeding is fast and uniform, and two 4kW, 8-pole motors provide the swinging power, achieving optimal swing amplitude and frequency.
The double-cranked arm push-pull mechanism ensures the synchronization of the feeding box's forward and backward movement, preventing deviations caused by uneven material distribution and uneven loading. Furthermore, the cranked arm structure reduces forward and backward movement times, improving efficiency and reducing material drop from the front end of the box into the mold.
The double-layered aggregate platform structure allows for wear over time; only the upper wear-resistant platform plate needs to be replaced, minimizing maintenance costs.
Stand Shaft Guide Mechanism
The stand shafts are Ø110 mm in diameter, made of 40Cr with a hard chrome plating, ≥25μm thick, and have a hardness of 800-900 HV.
The four stand shafts are spaced 2200 mm side-to-side and 980 mm front-to-back, providing a large span and a stable structure.
The upper die guide mechanism features an extended design for stable vertical movement. The guide sleeves contain thick-walled copper bushings and are equipped with lubrication ports and oil guide grooves for convenient and comprehensive lubrication.
The stand shaft's upper and lower mounting brackets, as well as the upper die mounting bracket, feature an externally accessible design. By removing the mounting bolts from the guide sleeves and synchronizer bracket, the stand shafts can be directly removed, making them easy to inspect and replace.
Mold assembly system
Airbag design
The lower die utilizes an airbag clamping mechanism, with four airbags per side, for a total of eight airbags. The clamping blocks are made of polyurethane with a hardness of 75-80 HV.
Carburizing treatment
Depending on the brick type, the lower die is either wire-cut or precision-machined, then assembled and welded. The lower platen and upper die presser are heat-treated and carburized, with a carburized layer depth of ≥1.2mm. The die body is constructed of wear-resistant steel, offering excellent wear resistance and minimal deformation. The upper die frame is welded from national standard steel plates, with the upper and lower surfaces machined to minimize weld stress. After design and mechanical analysis, deformation is ≤0.5mm under a cylinder diameter of 140mm, a pressure of 16 MPa, and approximately 25 tons.
High die strength. High precision.
The clearance between the upper die presser foot and the lower die cavity is tight, with a perimeter of ≤0.5mm. The mold boasts high overall strength and excellent wear resistance, guaranteed for ≥100,000 cycles. The upper and lower dies perfectly match, ensuring smooth material flow and demolding.
Customization is available. Customization options include the addition of a heating device to accommodate various special brick shapes.
Hydraulic system
Utilizes servo motors
The hydraulic motor is a 55kW servo motor, offering precise and accurate control while saving energy. The dual pump output and rational hydraulic system design improve efficiency.
The large hydraulic oil tank
It ensures ample circulation for the hydraulic oil, reducing heat generation. Internal heating and external cooling ensure the hydraulic station operates smoothly in both hot and cold weather.
Brand-name accessories, reliable quality
All hydraulic valves and pumps are imported and reliable. The oil pump (160-75L) is an American Albert brand, and the hydraulic valves are Vitos brand. High-precision proportional control valves ensure accurate movement.
