Description
Technical Field
The present invention relates to a cutting saw structure, and more particularly, to a cutting saw structure configured to form an inclined surface on a cutting edge of a saw body as a main portion, in which case cutting tips coupled to the cutting edge are also arranged obliquely at a predetermined angle with respect to a radial line of the saw body.
Background
Generally, a cutting saw for cutting a workpiece such as stone or metal is circular, and a cutting edge is formed around a circumferential surface. At this time, a soft saw body (rotary saw body) is welded and a cutting edge containing diamond powder excellent in wear resistance or a hard metal cutting edge is attached to manufacture a rotary saw.
In this case, a rotary saw having cutting edges attached thereto is formed by providing a plurality of heat dissipation grooves around a rotary saw body made of a disk material, and joining the cutting edges between the heat dissipation grooves by welding such as ultrasonic waves to form a disk-shaped rotary saw, wherein the corners of the cutting edges in the rotation direction are cutting edges.
However, since the conventional saw is a cutting saw in which the cutting edge of the saw body is manufactured in a direction parallel to the radial direction (parallel direction), there is a problem in that the cutting efficiency is lowered. A cutting edge is provided with: an inner blade surface which directly contacts a cutting object of the object to be cut with a strong force during cutting operation (directly contacts the object to be cut with a strong force when there is no cutting tip); an outer facet opposite the inner facet; and a peripheral edge surface, both ends are connected to the inner edge surface and the outer edge surface, and cutting edges are joined to the inner edge surface, but conventionally, the inner edge surface is formed so as to be arranged in a direction parallel to a radial direction of the saw body, and the cutting edges are also formed so as to be parallel to the radial direction of the saw body, and thus there is a problem that cutting efficiency is lowered.

Fig. 2 is a view showing one face of a cutting saw structure according to the present invention. Fig. 3 is an enlarged view of a portion of a cutting tip of a major portion of the cutting saw structure shown in fig. 2.

Fig. 6 is a front view showing a part of a saw body and a cutting tip constituting a chip saw structure according to the present invention.
Referring to the drawings, the cutting saw structure of the present invention comprises: a disc-shaped saw body 130; a plurality of cutting edges 134 formed on the circumference of the saw body 130; and a cutting tip 140 engaged with the cutting edge 134.
The saw body 130 has a disc shape, and a plurality of cutting edges 134 are arranged in the circumferential direction on the outer peripheral surface of the saw body 130.
In this case, the main feature of the present invention is that an inclined surface 134SF is formed in the cutting edge 134, and the cutting edge 140 is joined to the inclined surface 134SF so that the cutting edge 140 is disposed obliquely.
Specifically, the cutting edge 134 is composed of an inner edge surface, an outer edge surface 134BF opposite to the inner edge surface, and Zhou Renmian PF having both ends connected to the inner edge surface and the outer edge surface 134 BF. The inner blade surface is formed by the inclined surface 134SF, the inclined surface 134SF is inclined at a predetermined angle a with respect to the radial line DL of the saw body 130, and the cutting edge 140 is also inclined at a predetermined angle a with respect to the radial line DL of the saw body 130 when the inclined surface 134SF is joined to the cutting edge 140.
In the present invention, the inclined surface 134SF is an inclined surface such that it spreads at an acute angle range a with respect to a radial line of the saw body 130. In other words, the inclined surface 134SF is constituted by an inclined surface such that the inclined surface 134SF spreads within an acute angle range a with respect to a normal line of the circumferential surface of the saw body 130.
In the present invention, a plurality of cutting edges 134 are provided on the circumferential surface of the saw body 130, and a heat radiation groove 133 is provided between the plurality of cutting edges 134, and in this case, the plurality of cutting edges 134 and the heat radiation groove 133 are alternately arranged on the circumferential surface of the saw body 130, and a slit 133SL penetrating both sides while extending a predetermined distance from a part of the heat radiation groove 133 toward the center portion is formed in the saw body 130, and the slit 133SL is arranged to be inclined at an acute angle range a with respect to a radial line DL of the saw body 130.
The slit 133SL serves as a heat radiation function for discharging heat generated when the cutting saw structure of the present invention rotates at a high speed to cut the object 3 to be cut. In addition, the slit 133SL also functions to mark the center of the saw body 132.
Therefore, the saw body 130, which is a main part of the present invention, can be prevented from being degraded by heat to the maximum extent, and the life-prolonging effect can be expected by preventing the saw body 130 from being degraded by heat to the maximum extent.
In addition, since the present invention is a cutting saw in which the cutting edge 134 of the saw body 130 has the inclined surface 134SF having a direction not parallel to the radial direction, there is an effect of improving cutting efficiency. The cutting edge 134 includes: an inner blade surface that directly contacts the object to be cut with a strong force when performing cutting work (directly contacts the object to be cut with a strong force when the cutting tip 140 is not present); an outer edge surface 134BF opposite the inner edge surface; and a peripheral edge surface 134PF, both ends of which are connected to the inner edge surface and the outer edge surface 134BF, and the inner edge surface is joined to the cutting edge 140. In the present invention, the inner edge surface is formed as an inclined surface 134SF inclined with respect to the radial direction of the saw body 130, and the cutting edge 140 is also joined to the inclined surface 134SF, thereby forming a cutting saw inclined A with respect to the radial direction of the saw body 130, and thus, the cutting efficiency is significantly improved as compared with the conventional one.
In the present invention, as shown in fig. 6, the cutting edge 140 is formed in such a shape that the distance between both surfaces becomes gradually narrower from the lower end portion to the upper end portion when seen in a longitudinal section, so that the cutting edge 140 has a tapered edge with a wider upper portion and a narrower lower portion.
Therefore, when the cutting saw structure of the present invention is rotated at a high speed to perform the work of cutting the workpiece 3, not only the frictional force between the cutting surface of the workpiece 3 and the both surfaces of the cutting tip 140 can be minimized, but also the phenomenon that the both surfaces of the cutting tip 140 are worn out by the frictional force can be minimized, and thus, the effect of improving the cutting efficiency by the cutting tip 140 while further extending the life of the cutting tip 140 can be expected.
In the present invention, as shown in fig. 7, side inclined portions 141 are provided on both surfaces of the cutting edge 140 so that the cutting edge 140 becomes narrower from the base end portion attached to the inclined surface 134SF to the tip end portion, and a cutting sharp portion 142 is formed so that the tip end portion of the cutting edge 140 is sharp.
Therefore, the sharp cutting edge 142 formed at the tip of the cutting edge 140 makes the excavating function smoother when cutting the workpiece 3, and further reduces the overload when cutting the workpiece, and by minimizing the friction between the workpiece and the two surfaces of the cutting edge 140, the overload phenomenon on the cutting tool and the cutting device due to the friction between the workpiece and the two surfaces of the cutting edge 140 is prevented, thereby preventing the vertical expansion of the workpiece in advance, and obtaining the effect of a high-quality workpiece.
Further, since the plurality of grooves 134GR are provided on both surfaces of the cutting edge 134, heat generated when cutting work of the workpiece is performed is discharged through the plurality of grooves 134GR to perform heat radiation, and thus, a phenomenon that the workpiece is deteriorated due to overheating is prevented, thereby having an effect that it is possible to secure high quality of the workpiece generated after cutting the workpiece. At this time, by disposing the plurality of grooves 134GR formed on one side surface of the cutting edge 134 and the plurality of grooves 134GR formed on the other side surface of the cutting edge 134 at positions offset from each other in the left-right direction, heat can be smoothly dissipated by the plurality of grooves 134GR on both side surfaces of the cutting edge 134, and at the same time, the strength of the cutting edge 134 can be sufficiently maintained.
In the present invention, the Zhou Renmian PF of the cutting edge 134 is further provided with a plurality of auxiliary heat radiation grooves 134SG, and heat generated when the cutting operation of the workpiece is performed is radiated by the auxiliary heat radiation grooves 134SG, so that the phenomenon that the cutting edge 134 is deteriorated due to the fatigue accumulated heat of the heat generated when the cutting operation of the workpiece is performed is prevented, and thus, the life of the cutting edge 134 is further prolonged, and the life of the saw body 130 is also further prolonged by further prolonging the life of the cutting edge 134. As a result, the cutting saw structure of the present invention has an effect of more prolonging the life.

Fig. 8 is a front view showing a deformed structure of a cutting edge of a main portion of a cutting saw structure according to another embodiment of the present invention. Fig. 9 is a side exploded view showing another modified structure of the cutting edge of the main part of the cutting saw structure of the present invention. Fig. 10 is a side exploded view showing the structure of the cutting edge-to-cutting tip in the main part of the cutting saw structure of the present invention. Fig. 11 is a side exploded view showing the structure of the cutting edge combination cutting tip and reinforcing blade at the main part of the cutting saw structure of the present invention.
In the present invention, the cutting edge 134 has a tapered inner coupling support hole 134TCH penetrating through both surfaces and penetrating through an inclined surface 134SF, and a distance between upper and lower surfaces is gradually narrowed toward the inclined surface 134SF, and the base end portion of the cutting edge 140 has a tapered coupling edge 143 in which a distance between both surfaces is gradually increased toward the inclined surface 134SF of the cutting edge 134, and the cutting edge 140 is joined to the inclined surface 134SF of the cutting edge 134 by welding in a state in which the tapered coupling edge 143 is inserted into the tapered inner coupling support hole 134 TCH.
Accordingly, in a state in which the tapered coupling tip 143 of the cutting tip 140 is inserted into the tapered inner coupling support hole 134TCH of the cutting edge 134, the cutting tip 140 can be coupled to the inclined surface 134SF of the cutting edge 134 by welding, thereby having an effect that a process of coupling the cutting tip 140 to the inclined surface 134SF of the cutting edge 134 can be more stably and smoothly performed, and a fixing tool such as a clamp is not required before the cutting tip 140 is welded to the inclined surface 134SF of the cutting tip 140, so that a welding auxiliary tool can be reduced, and a welding work of the cutting tip 140 can be more conveniently performed.
The cutting edge 134 has a tapered outer coupling support hole 134TOH penetrating through both surfaces and penetrating through an outer edge surface 134BF, a distance between both surfaces is gradually narrowed toward the outer edge surface 134BF side, a reinforcing blade edge is disposed at a position facing the outer edge surface 134BF of the cutting edge 140, and a tapered auxiliary coupling blade edge 153 is provided at a tip end portion of the reinforcing blade edge 152 so that a distance between both surfaces gradually increases toward the outer edge surface 134BF side of the cutting edge 134, whereby the reinforcing blade edge 152 is joined to the outer edge surface 134BF of the cutting edge 134 by welding in a state in which the tapered auxiliary coupling blade edge 153 is inserted into the tapered outer coupling support hole 134 TOH.
Accordingly, in a state in which the tapered auxiliary coupling tip 153 of the reinforcing tip 152 is inserted into the tapered outer coupling support hole 134TOH of the cutting edge 134, the reinforcing tip 152 can be coupled to the outer edge surface 134BF of the cutting edge 134 by welding, thereby having an effect of more stably and smoothly performing a process of coupling the reinforcing tip 152 to the outer edge surface 134BF of the cutting edge 134, and also, the reinforcing tip 152 supports and reinforces the cutting edge 134 at a rear side at the time of cutting work of an object to be cut by the cutting edge 134, thereby having a phenomenon of preventing the cutting edge 140 from being broken during the cutting work of the object to be cut. Since the reinforcing blade 152 further improves the strength of the cutting edge 134 provided in the saw body 130, not only is it easier and faster to join the reinforcing blade 152 to the outer blade surface 134BF of the cutting edge 134 by the tapered auxiliary coupling blade 153 and the tapered outer coupling support hole 134TOH, but also the reinforcing blade 152 further improves the strength of the cutting edge 134, whereby an effect of preventing breakage or the like from being damaged by a cutting load when the cutting edge performs cutting work on an object to be cut can be expected.
