Definitions
- the invention relates to a tool for processing hard substrates such as concrete or rock according to the preamble of claim 1.
- blind holes or straight, slot-like Depressions in hard surfaces such as concrete or stone become tools with a carrier body that is required at its machining end area are provided with at least one cutting element.
- a tool whose support body consists of a tube, for example, is from the JP-58-81 1 known.
- connection surface for the cutting elements pointing in the machining direction have a certain width running parallel to the wall thickness of the carrier body, which can only be achieved by means of a carrier body with a very large wall thickness can.
- a large one leads Wall thickness to a very high weight of the tool and thus to a very poor handling of the same.
- the invention has for its object a manageable, economical to produce manufacturable tool, the support body of a low weight and has a large connection area for the cutting element.
- crimped area on the one hand becomes a very large connection area created for the cutting element, on the other hand, the wall thickness of the carrier body be kept very low, so that even with tools with a large Diameter the weight of the tool can be kept small.
- the width of the cutting element preferably greater than the wall thickness of the carrier body.
- connection surface in the circumferential direction expediently interrupted by at least one longitudinal slot, which is starting from the connection surface over part of the carrier body in the direction Includes recording area.
- the support body is designed as a disc.
- the cutting element is preferably at least a cutting segment is formed, which extends over part of the circumference of the disc extends.
- the cutting element is preferably from a cutting ring formed, which extends over the entire connection surface of the tube.
- the tool shown in Fig. 1 has a support body 2 in the form of a tube a small wall thickness W on. At a first free end area of the carrier body 2 protrudes from this a receiving area 1 in the form of a cylindrical Plugging in. At an opposite second free end region, the Carrier body an area crimped to the outside. This crimped The area forms a face with its face pointing in the machining direction Connection surface 4 for a cutting element 3 in the form of a cutting ring.
- the radial width B of the connection surface 4 corresponds to that twice the wall thickness W of the thin-walled carrier body 2 and the connection surface 4 is exceeded by the cutting ring in the radial direction at least on one side.
- the flanged area can, for example, compared to the rest of the Carrier body 2 may be arranged in such a way that the crimped area Wall thickness of the carrier body evenly overlaps radially on both sides.
- the crimped area can also be crimped inward, for example.
- the tool shown in FIGS. 2 and 3 has a carrier body 12 in the form of a thin-walled disc. By means of a receiving area 11 in the form of a central one The tool is connected to a device (not shown) through the passage opening bringable.
- the peripheral region of the carrier body 12 is crimped and the crimped area has a connection surface 14 with a parallel to the longitudinal axis of the tool extending width B for several cutting elements 13 in the form of Cutting segments that have twice the wall thickness W of the carrier body 12 corresponds.
- the connection surface 14 formed by the crimped area is shown in FIG Circumferential direction of several evenly distributed on the circumference of the support body 12 arranged longitudinal slots 15 interrupted.
- These longitudinal slots 15 extend from the circumference of the carrier body 12 over the crimped area and over a part of the carrier body 12 in the direction of the receiving area 11.
- the crimped area projects beyond the remaining part of the carrier body 12 on one side.
- the cutting segments protrude the flanged area or the connection surface 14 on both sides different levels.
- Bending is used to bend a free end area of the carrier body 2 understood the one parallel to the wall thickness W without substantial calibration may have extending extent that is at most twice the wall thickness W corresponds.
- the extent of the crimped area can be calibrated parallel to the wall thickness W of the support body 2 1.1 to 1.9 times the wall thickness W of the carrier body 2 correspond.
