Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a multi-head punching device for plastic profiles. Background Art

[0002] Plastic profile products are widely used: window frames, stair handrails, wiring troughs, skirting boards, special-shaped pipes, etc. The raw materials are mainly hard PVC, and a few are semi-hard PVC, soft PVC, polyurethane low-foaming materials, etc. At the beginning of the 21st century, about 95% of architectural plastic profiles were polyvinyl chloride profiles, and the rest were polypropylene, polyethylene, polystyrene and other plastic profiles. When processing the profiles, they need to be processed and punched by a punching device. However, most of the existing punching devices use artificial support materials when processing the profiles. When pressing and punching, if the vibration force of the punching device is too large, it is easy for the profile to break away from the manual pressing hand, and the holes on the control board are also offset, thereby reducing the use effect.
