Description
1 A Process for Producing Slots, Grooves and the Like Technical Field It is customary when creating slots or grooves in floors or walls, rocks, minerals or the like by manual means. In order to retrofit cables or pipes or cables, for example, by manual means, to first form two slots by means of diamond cutting disks, and then to chisel out the residual intermediate ridge. Percussive milling tools on the other hand are curvilinear and mill hard materials, that is, they are faster and more efficient under normal conditions, but not in all circumstances during manually guided operations in extremely hard concrete.
In order to eliminate the corresponding disadvantages slot-cutting tools of the conventional, or superimposed percussive kind are fitted to a drive according to the invention, and are alternately interchangeable with eccentrically, superimposed percussive, counterbalanced planar milling tools, and preferably operable at respectively optimum speeds.
In order to excavate not only grooves but also more broad-tracked and if need be deeper, planar milling may be practised according to the invention by way of several cutting disks, for example, either conventionally or under activation, spaced apart about 100 to 300mm from each other, pre-cutting to a depth of 100 to 300mm for example, and releasing the rock, mineral or the like .e for subsequent superimposed percussive milling to almost full depth, at comparatively low mass, high speed and low abrasion.
20 Background The eccentrically superimposed milling technology is set out in EP 91105584.8-2313 and also 88710058.4-2313 0329915.
SItObject of the Invention S 2It is an object of the present invention to substantially overcome or at least ameliorate one or more of the disadvantages of the prior art, or at least to provide a useful alternative.
Summary of the Invention Accordingly, the present invention provides process for producing at least one of slots, grooves, planar excavation of floors, planar excavation of walls, and planar excavation of minerals, the process including utilizing a drive to rotate a slot cutting disk in a first cutting, or excavation step, interchanging said disk with an eccentric, superimposed percussive, rotatable planar milling tool, and utilizing said tool in a second cutting or excavation step.
The invention provides a process for producing slots, grooves and the like, and also for planar excavation of floors, walls, minerals and the like, characterised by the interchangeability of slot-cutting disks with eccentric, superimposed percussive, slowly rotatable planar milling tool on a drive. A preferred process is characterised by the interchangeability of a single or multiple slot-cutting disks with eccentric, superimposed percussive, counterbalanced planar milling tools fitted to one and the same drive. In preferred embodiments of the invention, single or multiple slots are pre-cut and la eccentric, superimposed percussive planar milling is subsequently applied to the left or the right or to the respective residual ridge.
It is preferred that the slots are first pre-cut by way of two manually guided, driven disks arranged at a distance from each other, and thereafter, in a second operating pass milling out the exposed, residual ridge in eccentric, superimposed percussive fashion. In the eccentric, superimposed percussive mode of operation the tool/tools are counterbalanced by matching their weight to the counterweight on the eccentric drive shaft.
It is preferred that dynamic balancing is achieved through compensating by mass.
The slot-cutting tool or tools may be fitted to the rapidly rotating eccentric drive shaft or lo alternatively activated milling tools are flange-mounted interchangeably to the slowly rotating, superimposed percussive intermediate shaft. A slot-cutting tool may however also be fitted to the 00.
0. *.00 oo• o° shaft for percussive operation. Single or dual high-speed driven, conventionally rotating slot-cutting disks on the eccentric drive shaft may be provided with weights for counterbalancing.
Eccentric, internally meshing gear combinations may be used, in which the externally toothed gear is held static while the internal ring gear rotates about it at a reduced rotational speed, or vice versa. The respective drive may be stabilised in operation by its weight or by a massive mechanical guide means.
Best Mode or Modes for Carrying Out the Invention In figure 1, just a single example of execution having a drive for two systems on one and the same drive shaft. In this case a hand-held device having an electrical power rating ranging from 1500 to 2000 Watt and a rotational speed between 6000 and 12000 revolutions per minute, for example, (1) is the drive motor, is a quick-coupling for interchangeability, is the superimposing percussive system on the rapidly rotating eccentric drive having a counterweight and a reduction gear train for a planar milling tool operating under slowly rotating superimposed percussion only, or a single or dual slot-cutting tool (figures 2 and 6).
In figure 2 is again the drive motor, the quick coupling for interchanging one system for the other. in this case are two diamond cutting disks on the drive shaft, operating by direct S conventional propulsion at 6000 up to 12000 revolutions per minute under a superimposed percussion spaced apart by the approximate width of the tool in figure 1 applied according to the invention o° for slot-cutting, preferably for subsequent milling out of the residual intermediate ridge by way of the superimposed percussive tool (according to figure 1).
In figure 3, for example, are several pre-slotting disks operating either by percussion or conventionally by respectively propelling the shaft either slowly or rapidly.
In figure 4 the superimposed percussive tools then mill the residual ridges in a second operating pass with comparative ease. The interchangeability of both different systems on a single machine and/or shaft may be provided, but is not essential in this case; the process is claimed.
Figure 5 depicts a superimposed percussive, dual slot-cutting tool (11) is the holder for this special design and (12) is but one mode of propulsion for the rapidly rotating, driven eccentric sleeve (13) having a counterweight The reduction gear train depicted by (15) comprising a pinion meshing with an internal ring gear in order to thereby slowly rotate a superimposed percussive shaft in this case as an example of an alternative having an internal ring gear secured to a chassis.
Figure 6 corresponds to figure 5 apart from the single or multiple slot-cutting, or the depicted superimposed percussive planar milling tool (17) instead of the tool (10) of figure 5 fitted interchangeably.
In figures 7 and 8, a specially claimed design, a milling tool (18) shown in figure 7 fully excavates a slot of 30mm width for example. The technology corresponds substantially to that of figures 5 and 6, only the coupling and counterbalancing of the differently operating tools vary. In the case of figure 7 (18) is the fully excavating tool, which is interchangeably fitted to the comparatively Sslowly rotatable, driven shaft operating radially percussively.
C04018 3 In figure 8 item (20) is a dual, conventional rapidly rotating, driven slot-cutting tool without superimposed percussion, which is fitted in this instance to the rapidly rotating eccentric shaft (21).
(22) is the counterweight which is matched to the internal weight (23) of the eccentric shaft (21) for counterbalancing. Separate protection is claimed for the process of dual, conventional pre-slotting by means of the system of figure 8, and subsequently milling out the residual ridge (26) by superimposed percussion by means of the system of figure 7. In the design corresponding to figures 7 and 8 (24) is the static pinion meshing with the internal ring gear (25) in speed-reducing, eccentric fashion.
