Description

Cutting tool for cutting arc edge

Technical Field

The present invention relates to a connector, and more particularly to a cutting tool for cutting curved edges.

Background

Plywood for panel furniture (plywood) is commonly used for manufacturing furniture needing bending deformation; the performance of the core-board is sometimes affected by the material of the board core; the shaving board (also called as particle board and bagasse board) is loose in material and only used for low-grade furniture. The most cost effective, most commonly used is Medium Density Fiberboard (MDF). Common finishing materials for panel furniture include veneer (commonly known as veneer), wood grain paper (commonly known as sticker), PVC rubber plate, polyester paint (commonly known as baking finish), and the like.

Common artificial boards include cereal boards, plywood, core boards, shaving boards, medium density fiberboard and the like. The combination of the plate-type furniture is usually connected by various metal hardware pieces, so that the transportation is convenient, and because the original physical structure of the wood is broken through the base material, the deformation of the artificial board is much better than that of solid wood when the temperature and humidity change is large, and the quality of the artificial board is more stable than that of the solid wood furniture.

Common finishing materials for plate furniture include veneer, melamine impregnated paper, wood grain paper, PVC rubber plate, polyester paint, etc. The latter four veneers are commonly used for medium and low-grade furniture, while natural veneer veneers are used for high-grade products. The plate-type furniture is made up by using medium-density fibre board or shaving board and adopting the processes of surface facing and making them. A large part of this furniture is wood grain simulation furniture. The veneering of some panel furniture sold in the market is more and more vivid, the glossiness, the hand feeling and the like are good, and the product with fine technology is expensive. The natural veneer is difficult to maintain due to the use of solid wood veneer, and the wear resistance, the high temperature resistance and the waterproofness of the veneer are much lower than those of a melamine veneer.

In the production process, arc edge processing is usually required to be carried out on the plate of the furniture for the aesthetic or practical requirements of the furniture, but in the processing process, in order to ensure the precision of cutting scraps, a special clamp is usually required to ensure the cutting amount, the clamp is large and high in cost, and the arc edge cannot be accurately cut on the corner of the plate.
