Description

Technical Field

[0001] The invention relates to the technical field of sleeper production, in particular to an automatic embossing device for sleepers. Background Art

[0002] The sleeper is a kind of railway accessories. It not only supports the rails, but also maintains the gauge of the two rails, and evenly transmits the load, lateral force and longitudinal horizontal force transmitted by the rails to the roadbed. At present, prestressed concrete sleepers are widely used in railway construction due to their good smoothness, high stability, less maintenance and low cost.

[0003] In the production process of prestressed concrete sleepers, after the concrete mixed by the mixer is poured into the mold, the already poured mold needs to be vibrated, compacted and embossed. After each embossing, the embossed cover plate needs to be polished and cleaned and sprayed with a release agent in preparation for continuing the embossing of the next mold.
