Definitions
- Milling tool for machining wood, wood-based material, plastic or the like.
- a disadvantage of this milling tool is that the chips that are flung away have high kinetic energy and must be collected and transported away in a costly manner by complicated chip hoods with large amounts of suction air. As the cutting speed / speed increases, the suction speed and air volume required to collect the chips, derive them and existing guidelines with regard to the residual dust content of the air
- a circular saw device in which the inside of the saw blade is open towards the circumference of the saw blade, approximately radial to the central area Suction channels running towards it are provided, which open into a collecting space provided on a frame, which is connected to a suction device
- the object of the invention is to provide a device for removing the chips for milling tools with chip space or gap, which works with low energy and technical effort, with an impairment of the generated workpiece surface is prevented and the cutting edge wear is to be reduced
- the object is achieved in connection with the features mentioned in the preamble of claim 1 in that the chip space or the gap is formed as an opening for chip removal, the opening is approximately perpendicular to the cutting plane formed by the cutting edge and cutting direction, the opening being one Cross-section that is larger than the projected area of a chip that is cut with the cutting edge during the cutting process >
- the cutting edge is advantageously arranged at an angle of inclination K between 60 ° and 20 °.
- the front ejection opening can also be designed conically
- the opening for chip removal can be designed as an opening with a constant cross-section or widening to the end wall.
- the cross-sections are designed as slots or bores with little manufacturing effort
- the ejection opening and the tool circumference are advantageously applied according to the setting angle.
- the wall of the hollow tool body should be made as thin as possible. This minimizes the path of the chips in or through the tool
- the end face of the milling tool is advantageously designed (as a pipe connection) for adapting a chip disposal device.
- the chip disposal device can be provided with low power, which only serves to transport the milled wood chips from the tool to the chip bunker
- the cutting attachment is loosened in such a way that an unimpeded chip flow into the tool or into the gap is made possible.
- the cutting edge is firmly connected to the basic tool body by soldering, gluing or the like or is exchangeably fastened with a knife flap
- a thin-walled, cylindrical to conical installation which is adapted to the inner shape of the tool and whose outer diameter is slightly smaller is provided is than the diameter of the tool cavity, the installation having at least one chip window in the area of the opening for chip removal (effective point area), the so is dimensioned so that unhindered access to the chips can take place in the remaining tool cavity
- the fixed cylindrical to conical installation with a chip window prevents entrainment of the air mass in the mold cavity, so that it no longer escapes from the chip receiving openings as a result of the centrifugal force and thereby hinders the chips in their movement into the tool or even pushes them out fly unchecked through the chip window and meet an advantageously inclined guide element that guides them axially out of the tool
- clamping rings can be attached to the open side of the tool.
- FIG. 3 shows a perspective illustration of the basic tool body according to FIG. 2
- FIG. 5 shows a perspective illustration of the basic tool body according to FIG. 4
- Fig. 6 is a perspective view of the variant with the chip ejection between
- FIG. 7 shows a perspective illustration of the variant with the chip ejection to the open side of the tool facing away from the motor with a section of the basic tool body
- FIG. 8 shows a cross section through the milling cutter according to FIG. 7
- FIG. 2 shows a milling tool with a conical ejection opening 3 (conical tool cavity 11).
- Two cutting edges 1 are arranged opposite one another on the milling tool at a setting angle K of 45 °.
- an opening 2 for chip removal In front of each cutting edge 1 there is an opening 2 for chip removal, which leads to the ejection opening 3
- the opening 2 is tapered towards the ejection opening 3 and is designed as a slot on the front side 4
- Opening 2 is a profiled cutting edge 1 by means of a cutting attachment 5 (knife flap) so that the selected free cross-section of the opening 2 is not restricted.
- a clamping ring 6 comprising the end face 4 is also provided, which overlaps the slotted opening 2, and so for Increasing the rigidity of such a thin-walled milling tool contributes
- the clamping ring 6 is dimensioned so that it can be shrunk onto the milling tool
- the chips separated and accelerated with the cutting edge 1 are passed through the opening 2 in front of the cutting edge 1 to the ejection opening 3.
- the opposite end of the tool is closed and serves to receive the drive shaft.
- the chips come out of the tool independently with low power can be attached to the discharge opening 3 in order to transport the chips over a greater distance to a chip bunker
- FIG. 3 shows in perspective a milling tool corresponding to the representation in FIG. 2
- FIG. 3 only the rotationally symmetrical basic body without the attached cutting edge 1 with cutting edge attachment 5 and clamping ring 6 is shown.
- the design of the opening 2 and the ejection opening 3 can be clearly seen.
- FIG. 5 shows the milling tool according to FIG. 4 in a perspective view. The position of the openings 2 on the end face 4 of the milling tool is shown. At the center of the end face 4 is a bore for a drive shaft
- the cutting edge 1 lies obliquely in front of the circular opening 2.
- the cutting edge 1 is fastened here by soldering or gluing
- FIG. 6 is a perspective view of the variant with chip ejection between the tool and the motor / bearing plate with a section of the basic tool body 10 6 pushes the chips separated with the cutting edge 1 through an opening 2 lying in front of the cutting edge 1 and the chip window 8 of the stationary cylindrical to conical installation 7 located behind it in the effective point area (in relation to the chip trajectory 15) into the tool cavity 11
- the installation 7 is cylindrical or tubular, in order to obtain a good adaptation to the inner shape of the tool and the largest possible remaining tool cavity 11.
- the chips are flung onto a guide element 9 on the inner wall of the tubular installation 7 , the chips almost axially from the tool cavity 11, through the gap between the tubular installation 7 and the motor / bearing plate 14, formed by placing the tubular installation 7 on several feet 13, and through the gap between the basic tool body 10 / clamping ring 6 and Motor / bearing plate 14 leads to the ejection opening 3
- Fig. 8 the cross section through the milling cutter according to Fig. 7 is shown.
- the chip window 8 is aligned so that it covers the effective point area. With large changes in the cutting engagement depth, an adjustment of the position of the chip window 8 is necessary.
- the positioning of the chip window 8 to the effective point area takes place via a Lever mechanism 17, which is connected to an adjustable stop / table 16.
- the edge of the chip window 8, which lies in the direction of flight of the chips, is applied in order to hinder the chip movement as little as possible Reference list
