Abstract

The utility model relates to a highly polished woodworking circular saw, which belongs to the technical field of woodworking circular saws. The utility model is characterized in that the three cutting edges of each tooth surface of an existing circular saw blade are replaced by three single bladed knives, two side cutting edges are replaced by cutters, cross cutting edges are replaced by chip breaking knives, the cutting area and the cutting angle is equivalent to 1/10-1/4 of the original, and the utility model can be used for processing intractable veneer boards without stubble and residue, and the process quality can exceed the sanding quality by eliminating the run-out tolerance of the edges of the cutters. The utility model provides a new circular saw for wood surface processing industry, block board edge sealing finishing processing industry, veneer boards side sawing industry, etc., the utility model can make a high-quality and high-efficiency one-time accomplishment of sawing and high precision processing.

Description

Best bright finish is cut light garden saw

Best bright finish is cut light garden saw, belongs to the woodworking circular saw field.

Present art worker garden saw blade is made up of tooth and saw disc body.The front of each tooth is by two side tool swords, a horizontal blade surrounds, the area of cut is big, and three blades all in one plane, the cutting angle of blade can't be reduced, therefore the cutting angle of horizontal blade is big, and the cutting angle of side tool sword is bigger, the cutting resistance that makes present garden saw blade is than the high several times of garden saw cuts resistance of the present utility model, when the hardwood of dry processing, particularly hardwood plywood, because its thin hard and crisp bending strength is very little, the bottom surface periphery falls slag easily, and finished surface also has a lot of hair stubbles.Present garden saw blade has certain run-out tolerance when also making because of the saw disc body is thin, adding is having bigger component because of cutting resistance perpendicular to saw disc body direction again man-hour, make the side tool sword produce microdisplacement at the axis direction of cutter, the side tool sword Cutting trajectory that these two aspect reasons make each tooth is not point-blank, but swing, stay tool marks after the processing.Along with the increase of charging rate, the distance of two adjacent tool marks increases, and production efficiency will be subjected to the constraint of processed surface smoothness.

The purpose of this utility model: be in order to overcome above-mentioned shortcoming, to be wood surface processing, fine finishining before plate fitment, the core-board edge sealing, industries such as veneer saw limit provide a kind of sawing, and high accuracy processing is once finished, crudy surpasses the quality of sanding, quick novel carpenter garden saw.

Technical solution of the present utility model is: according to the reason that produces above-mentioned shortcoming in the carpenter garden saw blade processing now, the utility model adopts following solution: 1, three blades on the present flank of tooth are processed simultaneously, use two side tool swords on the alternative former flank of tooth of the very little single-blade cutting knife in cutting angle instead, replace horizontal blade on the former flank of tooth with the very little single-blade chip breaking cutter in cutting angle, like this three blades on the original flank of tooth, resolve into three single-blade sharp cutting knife and chip breaking cutter, the cutting function that substep alternately removes to become surely an original tooth, the area of cut, cutting resistance only has original 1/10～1/4, even so when processing thin and crisp unmanageable glued board, slag is not fallen on the surface yet, does not also have the hair stubble.

2, take measures to eliminate the distortion and the run-out tolerance of saw disc body, the Cutting trajectory that makes each cutting knife blade all point-blank, finished surface does not have tool marks again, also because the Cutting trajectory of cutting knife is parallel with machine tool guideway, production efficiency no longer is subjected to the restriction of charging rate, and efficient is than present garden saw blade height.

The good effect of utility model: the utility model can be sawing, and the fine finishining two procedures is once finished.Through facts have proved that crudy surpasses the crudy of external sander, and the efficient height.

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model welding tooth garden saw view

Accompanying drawing 2 is the utility model machinery clamping tooth garden saw views

With reference to the very for a short time single-blade cutting knife that good cutting arranged in accompanying drawing 1 and 2, one cutting angles of accompanying drawing 2. with single-blade chip breaking cutter 3., what replace is welded in (accompanying drawing 1) on the saw disc body periphery 1..Or 4. the single-blade cutting knife is fastened on the saw disc body periphery 1. by cushion block, 3. the chip breaking cutter 2. adjacent with cutting knife be fastened on cushion block 4. 1. go up (accompanying drawing 2) with the saw disc body.
