With the continuous progress of industrial technology, traditional machinery is gradually unable to meet the needs of modern production. Friction brick press, as an important equipment in the building materials industry, is also facing the challenge of upgrading. This paper will introduce the transformation process of the friction brick press in detail, from the mechanical structure to the electrical system, and comprehensively show the course of its digital transformation.

1. Transformation background and objectives

In the process of long-term use of friction brick press, its two-disc friction drive mode, motor and other components have gradually exposed the problems of low efficiency, high energy consumption and high maintenance cost. In order to improve production efficiency, reduce energy consumption and improve equipment stability, it was decided to transform it. The main goal of the transformation is to achieve digital control, improve production efficiency, reduce maintenance costs, and improve equipment safety.

2. Transformation implementation process

Mechanical part modification

First of all, we removed the two-disc friction drive system of the original machine, retaining the core components such as beam, base, column, tie rod, slider, screw, nut and ejector device. The spline sleeve is installed in the position of the screw flat wheel, and the servo motor is driven by the inner spline sleeve and the flywheel with the wheel groove, so that the rotating movement of the screw is transformed into the up and down reciprocating movement of the slider. This design simplifies the mechanical structure and improves the transmission efficiency.

In addition, for the lubrication system, we have retained the original lubrication device, and improved the lubrication of the spline sleeve and bearings, and added a pneumatic refueling machine. This automatic lubrication system controls the oil supply time and oil supply amount through PLC, which effectively reduces the mechanical failure caused by artificial refueling.

Electrical part reconstruction

On the electrical side, we removed the original motor, electrical cabinet and operator and replaced it with a servo motor drive system. The system has the advantages of strong overload capacity, excellent anti-biased load performance, wide speed regulation range, good acceleration and deceleration performance, frequent start braking and strong positive and negative switching ability. At the same time, the installation of centralized button stations and safety grating greatly improves the safety of operation.

Third, the performance characteristics after the transformation

Digital precision control: servo motor direct drive technology realizes digital precision control, makes the energy release more accurate, the product consistency is higher, and the pass rate is greatly improved.

Efficient strike speed: The touch screen can easily set the strike process, which can fully simulate manual operation. The continuous strike speed is very fast, which significantly improves production efficiency.

One-button operation: The modified equipment only needs one-button operation, which can automatically complete the whole process from light pressure exhaust of raw materials to heavy pressure molding of products, with a high degree of automation, reducing the difficulty of operation.

Energy saving and environmental protection: After the transformation, the equipment is highly efficient and energy saving, the power saving rate reaches about 55%, the starting current is small, and there is no impact on the grid, which meets the requirements of green production.

Prolong the life of the equipment: due to the cancellation of the transverse and radial screw force, the service life of the transmission screw, nut and die has been greatly improved, and the maintenance cost has been reduced by about 35%.

Safe and reliable: the addition of multiple mechanical and electrical safety protection measures effectively avoids the occurrence of safety accidents.

Through the transformation of the friction brick press, we have achieved a transformation from traditional to digital, improving the performance and efficiency of the equipment. This is not only the upgrade of technology, but also the practice of green and intelligent production concept. In the future, we will continue to be committed to the innovation and improvement of equipment, and contribute more power to industrial development.
