Description

Method for processing zigzag mark antique floor and milling machine thereof

Technical Field

The invention relates to a method for processing a floor and a woodworking machine thereof, in particular to a method for processing an antique floor and a milling machine for processing the antique floor.

Background

The antique floor becomes a name of fashion floor from the birth date. It can naturally reveal the style of antique color, clear texture, concave-convex surface or relief effect and antique features. The surface of the antique floor is not smooth and flat, but is washed for many years, and generally presents natural concave-convex and ancient traces, so that the antique floor gives out a dense historical feeling. More importantly, the antique floor is endowed with deep cultural and mental connotations. The archaized floor can meet the psychological needs of people for various emerging things only from the perspective of the archaized floor, and can meet the requirement of people on appreciation differentiation regardless of the expression form. The production methods of the antique embossed floor appeared in the time are basically three types: firstly, it utilizes the plank surface nature ground soft and hard different wooden texture, through with the steel wire wheel at plank surface milling brush, polish, grinds off the soft wooden of surface texture, lets the harder wooden texture of texture protruding for original smooth surface produces the three-dimensional decorative board according to the unsmooth form of wooden texture. Secondly, the surface of the board is burnt through flame spraying, the soft wood is seriously carbonized, the hard and compact wood is not carbonized or is slightly carbonized, and then the carbonized layer on the surface is removed through rapid and slight milling and brushing to generate a three-dimensional shape. Thirdly, the uneven wood-like texture is carved on the surface of the mould, and the surface of the wood board is rolled by the mould, so that the uneven three-dimensional shape with the wood-like texture is generated on the surface of the wood board. The wooden floor with vicissitudes feeling can be reflected, if the wood is cut by a manual large saw in hundreds of years due to the fact that tools are simple and crude, a strip of saw-tooth marks which are pulled back and forth by saw blades are left on the cut surface of the wood, the wood floor is a processing mark left hundreds of years ago, and the historical vicissitudes of the floor are reflected. However, with the development of industrial technology, the modern sawing of wood is performed by a high-speed band saw or a circular saw, and a back-and-forth obvious saw mark of a saw blade cannot be left on the cutting surface of the wood.

Disclosure of Invention

The invention aims to provide a wood floor processing method which is different from the traditional antique style floor which is milled, brushed and polished by utilizing natural wood textures or pressed by a mould, generates a strip of saw-tooth marks by milling with vivid effect and high processing efficiency, simulates a strip of saw-tooth marks left when a saw blade is pulled back to move on a wood cutting surface when the wood is cut open by manually pulling a large saw hundreds of years ago, and a milling machine for forming the wood floor with the saw-tooth marks.

The elastic device is characterized in that a positioning rod is arranged below the supporting plate, and a pressure spring is sleeved on the positioning rod between the bracket and the supporting plate.

The two sides of the frame are respectively provided with a left guide rail and a right guide rail for the tool rest to move back and forth, and the side surface of the tool rest is provided with a limiting roller matched with the left guide rail and the right guide rail.

The left and right guide rails are L-shaped, and the limiting idler wheels have two forms, namely an upper limiting idler wheel and a lower limiting idler wheel which are in contact with the horizontal plane of the L-shaped guide rail, and a left limiting idler wheel and a right limiting idler wheel which are in contact with the vertical plane of the L-shaped guide rail, and are used for respectively positioning the movable tool rest up and down and left and right.

The guide rod horizontally hangs out of the rack, and the guide sleeve sleeved in the guide rod upwards extends out of the knife rest and is used for limiting the upward jumping of the knife rest and guiding the knife rest in the process of moving back and forth.

According to the method for processing the antique floor with the sawtooth marks and the milling machine thereof, the cutter row consisting of a plurality of disc milling cutters is axially arranged on a rotating cutter shaft, the surface of a wood floor blank is milled through the cutter row, and a strip of saw marks (actually milling grooves) similar to saw cuts left by a saw blade are formed on the milled surface of the wood floor blank. The surface milling method is used to obtain saw cuts similar to those obtained by sawing with a saw blade. The method realizes vivid kerf effect and high processing efficiency. The milling machine for processing the zigzag archaized floor is simple in structure, can further process the floor with the arc surface, and is used for simulating the effect that the floor is bent and deformed after being used for years or decades after wood is cut by a large saw to be made into the floor. The surface of the wood floor blank is milled and polished, and then another antique floor with saw-tooth marks is manufactured by a method for making the existing floor on the market old in color, so that a new style is added for the antique floor, and the interest of the antique can be met.
