Abstract

The invention provides a bending machine for corrugated plates, which comprises a driving mechanism, a fixing block, a bending knife, a lower bending grinding tool and two bending gaskets. The driving mechanism is drivingly connected with the fixing block, the fixing block is provided with a fixing groove, and the bending knife is inserted in the fixing groove and connected with the fixing block. The two bending spacers are respectively arranged on both ends of the bending knife, and the two bending spacers are all arranged on the same surface of the bending knife. The two bending gaskets are at least partially inserted in the fixing groove and connected with the fixing block. The thickness of the bending spacer decreases uniformly from the end close to the side of the bending knife to the end far from the side of the bending knife. The driving mechanism drives the bending knife to move closer to or away from the lower bending grinding tool through the fixed block. The crease formed by the slightly deformed bending knife to the corrugated plate is straight, which avoids the deformation of the corrugated plate after bending, which is wide at both ends and narrow in the middle. The secondary processing reduces the processing cost of the corrugated plate.

Description

Bending machine for corrugated sheets

technical field

The invention relates to the field of door panel processing, in particular to a bending machine for corrugated panels.

Background technique

Wave board is a new type of fashion art interior decoration board. This decorative material is mainly used in decoration projects such as hotels, clubs, home decoration, dance halls, resorts, shopping malls, mansions, villas, etc. Display stand. Can replace natural veneer, veneer, etc. The wave board mainly has dozens of patterns such as straight ripple, water ripple, surf pattern, golden armor pattern, textile pattern, snow pattern, etc. The surface effects include pure white board, gold and silver paste, pearl board, star board, cracked paint board, imitation Stone and other nearly thirty kinds of effects.
