Definitions
- the invention relates to a method for producing a rotation disk for machining material surfaces, a rotation disk for machining material surfaces, and a tool for producing a base body of a rotation disk for machining material surfaces.
- Rotary disks for machining material surfaces are known from practice and can be designed, in particular, as a grinding tool which has a disc-shaped basic body, by way of which the rotary disk can be connected to a drive and on which a material machining pad is arranged.
- the material processing coating may be formed from individual sandpaper or abrasive fabric blanks, which are distributed in the circumferential direction one above the other lapping on a front side of the base body.
- the main body of rotation disks of the aforementioned type of glass fabric mats For this purpose, Glasgewebemattenzuitese be inserted into a mold cavity of a pressing tool on top of each other and pressed together using a casting resin or the like. Due to the structure of the glass fabric mats, the resulting base body has a substantially constant thickness over the surface of the main body, that is, there are no thickness jumps.
- the invention has for its object to counteract the disadvantages mentioned above.
- a method for producing a rotary disk which comprises a disc-shaped main body, which has a central receptacle for direct or indirect connection of a drive shaft, and a material processing cover, which is applied to a frontally arranged annular zone of the main body.
- the method comprises the following steps:
- the base body is formed or formed with a support lip
- the base bodies formed of glass fabric mats are supported by the supporting lips directly on a next rotation disk, so that the contact pressure required for bonding the material processing coverings can be reliably and selectively applied.
- the stack of base bodies is heated when applying the pressure, so that an adhesive for bonding the respective material processing cover to the respective base body is activated.
- an adhesive for bonding the respective material processing cover to the respective base body is activated.
- two-component adhesive systems or moisture-curing adhesive systems in which, where appropriate, a heating of the stack can be omitted.
- the stack of bodies each of which is covered with a material processing coating, centered by means of a rod which passes through the central receptacles of the body.
- the lips of the base body are preferably ground or deburred.
- the grinding of the lips is preferably carried out before stacking the body or before covering the body with the material processing coating, so that in addition there is a clean and uniform pressure edge over the circumference of the body during pressing of the material processing pads or when stacking the body.
- the invention also relates to a rotary disk for machining material surfaces, which comprises a disc-shaped main body, which has a central receptacle for the direct and indirect connection of a drive shaft, and a material processing cover, which is applied to a frontally arranged annular zone of the main body is.
- the main body is made of glass cloth mats and has in a lying at least near the peripheral edge portion on the side facing away from the material processing surface a lip which is at least partially formed circumferentially.
- the lip gives the body increased mechanical stability.
- the lip favors, as already mentioned above in connection with the method according to the invention, during the bonding of the material processing covering the pressing of the same to the main body.
- the basic body has a constant thickness over its base area, that is also in the Beriech the lip are no thickness jumps before.
- the lip is formed completely circumferentially.
- the lip can also be formed only partially in the circumferential direction of the main body.
- the lip can be arranged at different points of the base body.
- the lip can form the peripheral edge of the main body. Then, the edge of the body forms when stacking of basic bodies for tying the material processing cover directly the pressure edge or pressure edge.
- the lip may be in the form of a bead of the glass fabric mat construction which is spaced from the peripheral edge of the body.
- the bead can have a V, U or even trough-shaped cross-section.
- the base of the bead then forms the pressure-transmitting surface or line, which rests on the material processing cover of the next or adjacent rotary disk when pressing the respective material processing cover to the base body.
- the material processing coating may be formed from a plurality of abrasive blanks, which are distributed in the circumferential direction on the respective end face of the body overlapping each other.
- the base body can have a diameter between 90 mm and 230 mm.
- the lip may have a height between 1 mm and 8 mm.
- the invention also relates to a tool for producing a main body of a rotary disk for processing material surfaces, which is formed from a plurality of interconnected glass fabric mats.
- the tool comprises a mold cavity for receiving the glass fabric mats, which corresponds to the shape of the base body and comprises a portion for forming an at least circumferential lip of the base body.
- a casting resin or the like which connects the individual glass fabric mats to one another is introduced into the mold cavity.
- the production of the lip of the body can be achieved in particular by the fact that the section for forming the lip is a cross-sectionally edge-side bend of the mold cavity.
- the section for forming the then bead-shaped lip can be formed from a wave-like curvature of the mold cavity which is near the edge in cross section.
- the rotary disk has a plurality of spaced-apart in the radial direction of the base body lips.
- the tool for producing the base body is then formed corresponding thereto with a kink and at least one wave-like curvature or a plurality of wave-like curvatures of the aforementioned type.
- Embodiments of a rotary disk according to the invention and a method for producing a rotary disk according to the invention are schematic in the drawing shown simplified and are explained in more detail in the following description. It shows:
- Fig. 1 is a plan view of a main body of a rotary disk according to the invention
- FIG. 2 shows a section through the rotary disk according to FIG. 1
- Fig. 3 is an enlarged view of the area III in
- Fig. 4 is a section through an edge region of an alternative
- FIG. 6 shows a stacking process during the bonding of a material processing cover to the base body.
- FIGS. 1 to 3 show a base body 10 of a rotary disk for processing material surfaces, which represents a flap wheel or disk grinding disk in which a multiplicity of abrasive blanks are distributed in the circumferential direction on an annular zone 12 arranged on the front side to form a material processing cover are arranged one above the other lapping.
- the main body 10 is formed with a central receptacle 14, which serves for the direct or indirect connection of a drive shaft, via which the rotation disk can be driven in rotation.
- the base body 10 which for example has a diameter of 120 mm, is formed from glass fiber mats pressed together and glued together, so that the base body 10 has no thickness jumps over its lateral extent, but rather has a constant thickness.
- the base body 10 further has at its edge a lip 16, which represents an at least approximately L-shaped bend of the base body in cross-section and is formed completely circumferentially.
- the plane of the annular zone is formed at right angles to the axis of rotation.
- the annular zone may also be arched or sloping outwards.
- a lip 16 ' limits a base body 10' at its edge.
- the lip 16 ' is in the form of a bead of the base body 10' and has a substantially V-shaped cross-section.
- the radially outer flank of the bead forms the edge of the base body 10 '.
- FIG. 5 shows a further embodiment of a lip 16 "of a basic body 10" extending in the circumferential direction.
- the lip 16 " is also formed from an annular bead of the base body 10" and is spaced from the outer edge of the base body 10 ".
- the ring zone 12 of the base body 10 is occupied by the material processing lining representing disk pack 18 after the preparation of the respective body, wherein between the disk pack 18 and the base 10, an adhesive system is applied , Before covering the base body with the disk packs, the edges of the base body 10, that is, the support lips 16 are ground or deburred.
- base bodies 10 of the same design each of which is occupied by a disk pack 18, are then stacked on a centering rod 20, so that a lip 16 of a base body 10-1 on the disk pack 18 of a next rotation disk is provided with a Base body 10-2 supported.
