Definitions
- Material processing belts in particular grinding and / or polishing belts, and method for producing material processing belts
- the present invention relates to material processing belts, in particular to grinding and / or polishing belts for releasable attachment to the outer surface of a grinding roller and to a method for producing material processing belts.
- a generic material processing belt in particular a grinding or polishing belt, has a working surface, a first and a second end and an end-side connecting device for forming an endless belt.
- Grinding or polishing belts of this type are used in the form of endless belts closed to form rings for grinding or polishing round tubes, round timbers or the like.
- the sanding belt is placed with the working surface facing inwards, on the one hand around the workpiece to be machined and, on the other hand, placed directly around an sanding belt drive roller of a belt sanding device.
- the grinding belt ring is tensioned by the operator pulling the drive unit with the drive roller away from the workpiece.
- the grinding belt must be cut open, placed around the object to be processed and then closed again to form a ring.
- a two-layer belt which consists of an inner carrier belt firmly closed to form a ring and an abrasive belt releasably attached on the outside.
- the belt is placed on two rollers of a grinding device which are spaced apart from one another, the grinding surface coming to lie on the outside.
- the two ends of the sanding belt are complementarily shaped to form a positive connection with a flush, flat connection point. Due to the system, internal grinding and thus grinding of self-contained workpieces is not possible.
- Another possibility of closing opened grinding and polishing belts to form an annular endless belt is known from WO 97/20663.
- the grinding and polishing belts described there are provided for connecting the ends, not the entire belt, but only one by comparison glue a short partial cut in the vicinity of the ends
- the invention has for its object to provide a material processing belt, in particular a grinding or polishing belt, which can be easily separated and closed again to form an annular endless belt and which overall has a longer service life.
- a method for producing such material processing belts is to be specified
- the connecting device is designed as a releasable positive-locking connecting device with at least one recess with a closed edge at the first end and at least one counterpart at the second end, thereby releasing the connection during the transmission of the rotational movement of the grinding roller is safely prevented during the grinding process, even with high tensile forces
- a key idea of the invention can be seen in the fact that the two ends of a material processing belt are closed by means of a positive connection, in which the closed edge of the opening prevents the opening from widening when tension is on during operation the material processing tape is exerted.
- Tests have surprisingly shown that material processing tapes, the ends of which are connected by a positive connection according to the invention, have extremely good running properties. In comparison to an adhesive connection, the connection transition is softer, so that the presence of the transition point is hardly noticed during operation
- a major advantage of the solution according to the invention is, moreover, that the positive connection can be released and reclosed as often as required. In addition, no further materials and / or tools are required for the production and separation of the connection. This means, in particular, that there is no waste Closing the positive connection can be carried out very quickly, which is also of considerable use in practice
- the material processing belts do not have to be pre-closed, but can be shipped and stored in a space-saving manner in the open state
- a first work surface and a second work surface are present on the side opposite the first work surface, the first work surface being on the outside in a first state of the material processing belt, wherein in a second state of the material processing belt the second surface is on the outside, and wherein the material processing belt can be reversibly moved from the first state to the second state
- This material processing belt unfolds its advantages particularly in connection with a detachable form-fitting connection, since the material processing belt can then be opened very easily and quickly and then closed again in such a way that the required work surface comes to lie on the inside
- a major advantage of such a material processing belt is also that practically the entire surface can be used as a work surface. This increases the service life of such a material processing belt and material costs can be saved
- a first and a second blank of a material Processing tape are made from adjacent pieces of tape meter goods and that in a common process step with the help of one or more punching tools, at least one recess is machined in the first blank and at least one counterpart in the second blank
- the main idea here is that two blanks for material processing tapes adjoining one another on the strip meter goods are processed in one process step, as a result of which the production process is accelerated in time
- this process saves time and equipment-consuming emptying and clamping processes as well as adjustments of the workpieces. Furthermore, the method according to the invention results in fewer rejects and only extremely low material waste
- the invention can be further developed in an advantageous manner in that at least two recesses are provided at the first end and a corresponding number of counterparts are provided at the second end.
- the tensile forces acting on the connection during operation are distributed over a plurality of form-fitting connections. or polishing tapes can be an advantage
- the at least one recess is perforated with a closed edge and the at least one counterpart is head-like. This means that it is particularly easy and quick to release and reclosable and that it can be subjected to high loads during operation be, which consists of an end-side expansion, the "head”, and a neck-like narrowing
- Such a material processing belt can advantageously be further developed in that the recess is designed as an elongated hole in the belt length and that the length of the hole corresponds approximately to the width of the "head".
- the second end with the counterpart can then be closed in a simple manner to close the connection be inserted into the holes at the first end
- the material processing belt in such a way that the perforation has a first and a second region, the extent of the first region in the transverse direction of the material processing belt being greater than that of the second region
- the perforation is arranged in such a way that the first region faces the first end and the second region faces the first end.
- the counterpart it is expedient for the counterpart to be formed by the fact that at the second end the Material recesses are machined on both long sides at opposite points
- the positive connection is closed approximately as follows. First, the second end is inserted into the elongated perforation until the material recesses at the second end lie in the plane of the first end, and then the second End shifted in the perforation until the neck given by the material recesses is in the first area of the perforation, the extent of which in the transverse direction of the material processing belt is preferably chosen to be so large that the positive connection can be produced by rotating the second end in the perforation
- the carrier material of the material processing belt has mechanical properties that do not allow sufficient stability of a positive connection consisting of recess and counterpart, it can be advantageous if a surrounding area of the at least one recess and / or the at least one counterpart is stiffened
- edges and / or the corners of the material processing belt are rounded off. This facilitates the insertion of the second end into the elongated perforation and the turning in the perforation, for example
- the presence of two working surfaces on the material processing belt allows, for example, the first working surface to be designed as a grinding surface and the second working surface as a top surface.
- a material processing belt is an extremely practical tool, especially if it is additionally equipped with a quick and easy-to-release form-fit connection. since in many operations, grinding and then polishing must take place.
- one grinding and one polishing belt are available in one
- both the first and the second work surface are designed as grinding surfaces or as polishing surfaces.
- Such material processing belts can be preferred, for example, when very large surfaces have to be ground or polished, ie when wear on at least one work surface is to be expected during the machining process. It is then not necessary to first obtain and install a second material processing belt, but after the first working surface of a material processing belt has worn out, this can be turned over once and the second working surface can then be used.
- material processing belts can be useful for certain fields of application, in which the first and the second work surface are designed as grinding surfaces with different grain sizes or polishing surfaces with different fineness.
- a preferred development of the method according to the invention consists in that the first blank and the second blank are separated from one another after the common method step has been carried out. Should e.g. In a further process step, which follows the common process step, the edges of punched perforations and material recesses are rounded off, it can be advantageous if the two blanks are not yet separated from one another.
- first blank and the second blank are separated from one another in the common process step.
- the tape material used is a comparatively tough or hard material, it may be desirable to reduce the force required for punching. This can be done in that the punching operations are carried out with a time delay in order to distribute the force required for punching.
- one of the materials felt or conveyor belt, textile belt with abrasive grain layer, composite material with a glass filament layer and a nylon fleece layer, which is interspersed with abrasive grains, or a composite material with two abrasive belts, the backs of which are glued together is used as the tape material.
- a hardening agent is applied to the at least one recess and / or the at least one counterpart for reinforcement in the surrounding area. This can be done, for example, by immersing the ends of the blanks in a suitable agent, such as bone glue, phenolic resin or the like.
