Definitions
- the invention relates to a trim for frame saws, with a first bar, which protrudes laterally, Pins penetrating openings of the saw blade has at its free end obliquely inwards Form running tightening surfaces and thus each into a cylindrical opening in a second bar intervention.
- a trim for frame saws of the type mentioned is known from DE 37 18 042 C2, the tightening surfaces the journal of oblique cylindrical journal sections are formed, which at an angle of inclination directed obliquely towards the fishing attack surfaces run.
- This course are the cylindrical ones Adjusted openings of the second bar.
- the assembly or disassembly of the second bar must therefore in Direction of the oblique course. Besides, is working in the openings at this oblique angle make what is not technically as proves favorable.
- the object of the invention is based on the object specify a fillet of the type in question, which in addition to a simplified production facilitated assembly and disassembly and which with loads occurring during sawing a system of the last trim on the saw blade guaranteed.
- the second bar is also not at an angle of the oblique course of the pin section as in the prior art.
- the pull-in area of is simple the outer surface of one with its base facing outwards facing truncated cone section.
- Such Shaping to create the tightening surface is easier producible as an oblique to the axial direction of the Spigot section.
- the Design according to the invention the advantage that Pressure point between the contact edge and the tightening surface with greater distance from the facing broad surface of the saw blade proceeds with the realization of favorable leverage ratios connected with that the second bar firmly against the broad surface of the saw blade facing her is pressed.
- the truncated cone section connects to a collar of the pin.
- This collar extends through the saw blade opening, which is chosen so large that the truncated cone section can enforce them. It is also provided that the base diameter is about the inside diameter of the Last opening corresponds. This allows after Pushing the saw blade onto the peg the unobstructed Attach the second bar. After that are the two strips in a manner known per se using one or more screws, which reach through the saw blade.
- Another beneficial one Characteristic is that the axial length of the fret is slightly smaller than the thickness of the saw blade. This prevents the second bar in a support position can reach the federal government and thus the tension effect of the second bar on the saw blade impaired. The invention then provides that the length of the truncated cone section is somewhat larger is the material thickness of the second bar.
- the base edge can so do not dig into the opening. It is always ensured that the contact edge of the opening at the slant inward pulling area becomes effective.
- a Tension reserve is realized according to the invention in that one on the outside, opening towards the saw blade Air gusset between the contact point Provide opening wall and pin wall.
- the pin is made of harder Material is made up as the second bar. This leads to to the fact that a deformation in the area under pressure the contact edge of the last opening is possible.
- the number 1 is suitable for frame saws Saw blade designated. This has on one Longitudinal edge saw teeth 2. At the narrow ends is 1 ', 1' ' the saw blade with a trimming 3 each Interaction with known, not illustrated Fishing, which in a saw frame of a frame saw are clamped, mostly several saw blades 1 are arranged in parallel next to each other, for example. sawing boards from tree trunks.
- Each fillet 3 has a first, against the a broad side surface of the saw blade 1 treading bar 4 and a second one arranged at the same height Bar 5, which on the other broad side surface of the Saw blade rests.
- the first bar 4 is a carrier a plurality of pins 6, which are parallel in rows are arranged to the longitudinal edge of the bar 4. The distance between the pins 6 is the same.
- the pins 6 cooperate with a series of saw blade openings 7, the hole spacing the distance of the Pin 6 corresponds to each other, so that the first Strip 4 in plug connection to the relevant narrow end 1 ', 1' 'of the saw blade 1 can be brought.
- the second bar 5 is also in series with one another arranged openings 8, in which the pins 6 passing through the saw blade openings 7 intervention.
- the hole spacing between the openings 8 corresponds to the hole spacing of the saw blade openings.
- the second bar 5 is placed so that it in aligned opposite to the first bar 4 is.
- each pin 6 is riveted to the first bar 4.
- the pin 6 has a rivet attachment 10, which passes through a bore 11 of the first bar 4 and is fixed there by means of a rivet head 12.
- the outer diameter u is slightly smaller than the diameter x of the saw blade opening 7.
- the one lying in the axial direction Length b of the collar 12 is also less than the thickness a of the saw blade 1.
- the Waistband 12 In contrast to the rivet attachment 10 follows the Waistband 12 with its base 13 facing outward Truncated cone section 14.
- the base diameter y corresponds approximately to the inner diameter z of the last opening 8, so that the second ledge 5 on the truncated cone sections 14 of the saw blade openings 7 reaching through Pin 6 can be attached. That means, that the diameter x of the saw blade opening 7 is the base diameter y corresponds.
- the length d of the truncated cone section 14 is, as can be clearly seen in FIG. 2 is slightly larger than the material thickness c of the second Bar 5. Accordingly, the base surface of the truncated cone section is 14 something about the broadside surface in question the second bar 5 in front.
- Attaching the saw blade 1 and the second Bar 5 takes place in the direction of the surface normal, because not only the saw blade openings 7 in the surface normal lie, but also the cylindrical openings 8th the second bar 5. This ensures that the screw openings 17 for the passage of the two Last 5, 6 connecting screw 9 always in optimal escape position and still a tightening torque is generated towards the saw blade 1.
