Description

A beam pulling mechanism

technical field

The utility model belongs to the technical field of thermoplastic plastic processing and molding, and relates to a beam pulling mechanism.

Background technique

Thermoplastic molding is the process of heating a thermoplastic sheet to its softening point, stretching it onto a single-sided mold and holding it in place while cooling and solidifying into the desired shape, clamping the thermoplastic sheet in the holding device and heated in an oven to soften by convection or radiant heat. The sheet is then held horizontally on the mold and pressed or stretched onto the mold using vacuum pressure, air pressure or mechanical force. The softened sheet conforms to the shape of the mold and remains in place until it cools. Excess material is then trimmed away and the formed part is released. Trimmed material can be reused, mixed with unused plastic, and remanufactured into finished products.

Existing thermoplastic sheets are often limited by their width when being transported, and cannot be accurately transported to each station.
