Impact roller is successfully applied to high-speed roadbed

<

Recently, the complete set of compaction equipment for impact roller produced by the 20th Bureau Group Engineering Machinery Plant was applied to the subgrade construction of the test section of Chongqing Wushao High-speed Railway for the first time, and achieved remarkable results.

After the roadbed is compacted by the vibratory roller to the designed compactness standard, the impact roller is used for reinforcement and compaction. The settlement of the roadbed reaches 8 cm, the settlement is obvious, and the uniformity and overall strength of the subgrade are significantly improved.

Sheet Metal Laser Cutting Machine

Superior performance, you know it after using it

New generation of laser cutting machine of the plate machine series

High-load mechanical structure bed, stable processing and high precision

The mobile gantry structure is adopted, and the beam and the bed are integrally processed. The equipment has high precision, good rigidity and stable operation.
Machine base: frame structure welded with high-quality pipes, professional welding, secondary aging treatment, and precision machining by large-scale gantry milling machines. These design and processing methods ensure that the machine tool has excellent shock resistance, high rigidity and stability.
A dust cover is installed on the guide rail to prevent dust debris from falling into the guide rail to affect the movement, keeping clean and smooth movement.
The Z-axis device mainly realizes the up and down movement of the cutting head, which is completed by the CNC system controlling the servo motor. The motor drives the linear module, and the Z-axis slide plate to reciprocate up and down.
The follow-up has high precision and good stability, thus ensuring the cutting quality.
The focal length of the cutting head can be adjusted automatically or manually, and the position of the focal point can be adjusted according to the material and thickness of the cutting material, so as to obtain a good cutting section.
