Abstract
The utility model relates to a hard alloy saw blade, and belongs to the technical field of cutting tools. The saw blade comprises a saw blade substrate and alloy teeth, and is characterized in that even-number hard alloy teeth are uniformly welded on the periphery of the saw blade substrate, and forwards inclined surfaces of the alloy teeth are sharpened so that the forwards inclined surfaces of the alloy teeth are oblique to an axis in a crossing manner, and then a radial cutting edge is formed, wherein the double-surfaced side edge and a radial surface are both oblique to the axis in a crossing manner. The hard alloy circular saw blade has the advantages that the hard alloy circular saw blade is applied to the field of aluminum alloy, woods, plastics and the like, leads cut surfaces to be smooth and flat, is applicable to precisely cutting and collecting sawing chips easily and is more favorable for environmental protection.
Description
[technical field]
Two-sided side edge sintered carbide circular saw belongs to the cutting tool class, is useful for cuttings such as aluminium alloy, timber, plastics.
[background technology]
The alloy type saw blade is used for cutting metal, plastics, timber etc. more in the market, and this class saw blade has only the radial cuts sword, axially the two sides has larger area alloy and material to be cut high-speed friction to produce high temperature, cause the face of being cut off to occur that section burns, phenomenon such as sticky, coarse, and the feed resistance is big, sawdust mostly is Powdered (plastics, artificial sheet material), and environmental pollution is bigger.
[summary of the invention]
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can accurately cut and environmentally friendly alloy saw blade.
The utility model is on the basis of conventional alloys saw blade, adopts special sharpening method, the rake of alloy is intersected favour axis (AB flute profile), all intersects the radial cuts sword that favours axis on axial two-sided side edge and the sagittal plane and form.
The cutting edge of conventional alloys saw blade is on the diametric plane of saw blade rotating shaft.Cutting mode is that a tooth one tooth ground plane is disconnected.For repeatedly reconditioning and requirement of strength, the both sides of tooth are parallel to the alloy that substrate has certain area.When saw blade rotates at a high speed and cut material body friction, causing being cut off face has and phenomenon (during the cutting different materials) such as burns, bonding, section out-of-flatness, feed resistance are big.Be difficult to reach the purpose that essence is cut at some material.And the sawdust that scales off mostly is Powdered (as plastics, wood-based plate etc.) greatly, and environmental pollution is very big.
The utility model is two-sided side edge, and what promptly contact with the face of being cut off is blade (accompanying drawing 3), has not had to be parallel to the rubbing surface of substrate, has overcome the above-mentioned shortcoming of conventional blade.And on the sagittal plane of rotating shaft, and the radial cuts sword that all inwardly alternately tilts about forming naturally.Shake to saw blade in the cutting process has certain inhibitory action.Conventional blade has only the radial cuts sword, and blade parallels to the axis, and digs rake and sawtooth recess that bits down are attached to blade, then radially around brute force dish out, bring difficulty to the collection of dust.This saw blade is designed to the side edge helical teeth.The radial cuts sword of A tooth, B tooth, intersection favours saw blade axis (accompanying drawing 3), has not had the bits space, Tibetan of paralleling to the axis.And bits are sheet (look different cut material different), the most of sawdust after the cutting-out along hypotenuse " 1 " and substrate chamfering " 3 " respectively a little less than sawing the plate two sides power move (accompanying drawing 2, accompanying drawing 3), be convenient to the dust suction collection and separate with dirt, gas.Thereby reach the environmental protection purpose.
[description of drawings]
Accompanying drawing 1 is a front view.
Accompanying drawing 2 is the local amplification of front view.
Accompanying drawing 3 is the local amplification of vertical view.
[specific embodiment]
The utility model evenly welds the even bit hard-metal insert on the circumference of the circular substrate that center mounting hole is arranged.The profile of tooth 2-10 degree that leans forward, flank sword and back of tooth angle are 70-80 degree (accompanying drawing 2), profile of tooth is A, B; A, B arrange (as accompanying drawing 2, accompanying drawing 3) and form two-sided side edge.A tooth hypotenuse 2 protrudes in substrate a face, and with substrate a face the angle of 0-5 degree is arranged.The hypotenuse 1 of A tooth is the 30-50 degree with the angle of hypotenuse 2, and hypotenuse 1 ends at substrate b face.The identical sword face with the A toothing of B tooth is opposite.Substrate respectively at the back of the body sword side recess chamfering of A tooth, B tooth (as in accompanying drawing 2, the accompanying drawing 3 " 3).
Claims (1)
1. two-sided side edge sintered carbide circular saw comprises matrix and evenly is welded in hard-metal insert on the matrix circumference that carbide button is interlaced arrangement, intersects inside radial cuts sword about it is characterized in that having on two-sided side edge and the sagittal plane.
2. two-sided side edge sintered carbide circular saw according to claim 1 it is characterized in that carbide button is interlaced to be uniformly distributed in the substrate circumference, and the quantity of carbide button is even number.
3. two-sided side edge sintered carbide circular saw according to claim 1 is characterized in that the carbide button profile of tooth slightly leans forward, and rake and back of tooth angle are less than 80 degree.
4. two-sided side edge sintered carbide circular saw according to claim 1 is characterized in that carbide button profile of tooth lip surface and back of the body sword face all favour the substrate axis.
5. two-sided side edge sintered carbide circular saw according to claim 1 is characterized in that the back of the body sword side recess chamfering of substrate respectively at A tooth, B tooth.
