Multifunctional woodworking milling cutter used for milling edge portion of veneer shaving board

Abstract

The invention discloses a multifunctional woodworking milling cutter used for milling the edge portion of a veneer shaving board. The multifunctional woodworking milling cutter comprises a cutter bodyof a disc shape. A center shaft hole is formed in the center of the cutter body. Four to eight multifunctional combination spiral cutter tooth sets are arranged on the periphery side face of the cutter body and are distributed in a central symmetry manner. The central angle corresponding to each multifunctional combination spiral cutter tooth set is 360 degrees. Each multifunctional combination spiral cutter tooth set is composed of six cutter tooth bases fixedly connected with the cutter body, and spiral cutter teeth fixedly arranged on each cutter tooth base. According to the multifunctional woodworking milling cutter used for milling the edge portion of the veneer shaving board, the quality of the machined surface can be improved, cutter tooth abrasion and tipping are reduced, then themilling efficiency is improved, the production cost is reduced, and the machining environment is improved.

Description

technical field [0001] The invention relates to the technical field of cutting processing of wood composite materials, in particular to a multifunctional woodworking milling cutter used for milling the edges of veneered particle boards. Background technique [0002] At present, most wood-based panels need to be milled at the edge. Milling the edge of the wood-based panel has the following technological purposes: ①Through end milling, the processing allowance in the length and width directions of the wood-based panel is milled off, which is convenient for man-made Fix the length and width of the board size to meet the specified size requirements; ② Make the edges of the board neat, meet the requirements of verticality and parallelism in all directions, correct the error of the previous processing, and improve the specifications of the board; ③ Reduce the edge of the wood-based board The surface roughness of the inner part can be improved to improve the surface quality and pro...

Problems solved by technology

[0003] However, when using a milling cutter to process the edge of the board, especially the edge of the veneer particleboard, because in the direction vertical to the board surface, there are great differences in the density, hardness, strength and aggregation state between the veneer, surface layer and core layer particles. Differences, when using traditional milling cutters, when the same cutting force acts on these parts with obvious differences in properties at the same time, the internal stress and strain type displayed by each part after the force is different, so it is very easy to Processing defects such as digging, peeling, and splitting occur

In addition, due to the influence of coarse shavings on the core layer, the cutting edge of traditional milling cutters is easy to wear and collapse, and chips are easy to jam between the cutter teeth, making it difficult to remove chips, making it difficult to guarantee the processing quality and efficiency
