Abstract

The utility model relates to a mechanical processing milling tool for rabbet wood floor, which can prevent shrinking, cracking and expanding proof tongue-and-groove wood flooring, and belongs to the processing milling tool for wood floors; the mechanical processing milling tool for rabbet wood floors mainly solves the problems that the existing milling tool can generate floor shrinking, cracking and expanding; the utility model is characterized in that a cutter body 1 is made to a gear milling shape; the milling blade of each gear milling is composed of a compression vane interface milling blade 3, a rabbet concave plane milling blade 4 and a rabbet concave groove milling blade 5; a cutter body 2 is made to a six-gear milling shape; the milling blade of each gear milling is composed of a compression vane milling blade 6, a rabbet convex plane milling blade 7 and a rabbet convex face tenon milling blade 8; the utility model can be widely used for processing enterprise wood floors.

Description

Anti-shrinkage cracking, expansionproof tongue and groove timber floor machining milling cutter

The utility model relates to a kind of timber floor machining milling cutter.

Wood floors have been used for the finishing of chamber by numerous citizen, existing common tongue and groove wooden floor groove processing milling cutter, when the integral slab face after the timber floor that Milling Process becomes is mated formation was subjected to humidity, wooden absorbing environmental moisture made plate face physical dimension become big, easily produces local blow-up, when environment gas branch is too dry, wooden volatilization moisture, plate face drying shrinkage, physical dimension diminishes, plate joint generation longitudinal cracking and vertical depth influence the sense organ effect and the serviceability of the back plate face of mating formation more than 4 millimeters.

The purpose of this utility model is to provide a kind of novel wooden floor groove milling milling cutter, and the timber floor that processes with this milling cutter has good anti-shrinkage cracking and expansionproof performance, overcomes the deficiency of existing timber floor.

The utility model is to realize like this, this milling cutter is made up of tongue and groove matrix facing cut cutter (seeing accompanying drawing 1) and tongue and groove convex milling cutter (seeing accompanying drawing 2) two parts, cutter hub 1 is made six mill teeth shapes, and the milling edge of each mill teeth is to flog interface milling edge 3, tongue and groove matrix facial plane milling edge 4 and tongue and groove matrix face groove milling edge 5 by compression wing to constitute; Cutter hub 2 is made six mill teeth shapes, and the milling edge of each mill teeth is to be made of compression wing milling edge 6, tongue and groove convex facial plane milling edge 7 and the only milling edge 8 of tongue and groove convex face tenon.

Advantage of the present utility model is that processing is simple, and cost is low, is easy to produce in batches, and it is very convenient to install and use, and has with its timber floor that processes fabulous nonshrinkly to split, the expansionproof performance, have a extensive future.

Fig. 1 is a tongue and groove matrix facing cut cutter structure schematic diagram, and wherein 1 is cutter hub, and 3 flog the interface milling edge for compression wing, and 4 is tongue and groove matrix facial plane milling edge, and 5 is tongue and groove matrix face groove milling edge, and 9 is installing hole.

Fig. 2 is a tongue and groove convex facing cut cutter structure schematic diagram, and wherein 2 is cutter hub, and 6 is the compression wing milling edge, and 7 is tongue and groove convex facial plane milling edge, and 8 is tongue and groove convex face tenon milling edge.

Below in conjunction with accompanying drawing the utility model is described further: after the cutter machine-shaping, by installing hole 9 tongue and groove matrix milling cutter and tongue and groove convex milling cutter are fixed on the rotating shaft, during the processing floor, wooden floor chip is placed between two cutters, the tenon of the groove of matrix face and convex face on same level height, the moulding of timber floor time processing.

Claims

1, anti-shrinkage cracking, expansionproof tongue and groove timber floor machining milling cutter, it is made up of tongue and groove matrix facing cut cutter and tongue and groove convex milling cutter two parts, it is characterized in that:
