Definitions
- the invention relates to a method for adjustment of a punch relative to a die in sintering presses according to the preamble of claim 1.
- a burr is with Compacts not desired, especially with such compacts, which are then coated. It is known, for example cutting inserts for milling, turning and Manufacture drilling tools in the sintering process. It is further known, such compacts with a hard material layer to coat. Now the compact shows a ridge there is a risk that the ridge will break and thereby at crucial points, namely the cutting edges, the necessary hardness can no longer be found. On the contrary, the tool wears out particularly quickly. To such Facing consequences is removing the ridge required.
- the invention has for its object a method for setting a stamp relative to a die Sintering presses to create a small and uniform Gap over the scope can be realized.
- the method according to the invention relates to sintering presses, who work with an upper and a lower stamp, i.e. where a through die hole is provided is.
- the lower punch usually in the die hole
- the upper stamp releases them so powder from can be introduced above.
- the upper stamp into the die hole with the specified force and retracted via a predetermined path, if necessary with simultaneous Actuation of the lower stamp.
- the punch is moved towards the die hole until it is in a position just before immersion.
- the area the stamp is illuminated, and on the side facing away from the stamp
- the side of the die becomes an optical pickup positioned, which engages the die hole. It understands themselves that for this purpose the lower stamp is so far from the The die is withdrawn as an optical pickup can be positioned below the die hole. With the help of the optical pickup, the die hole is made recorded and displayed on a monitor.
- the diameter of the stamp is for obvious reasons minimally smaller than the diameter of the die hole, so that the stamp can move relatively freely in it. Therefore there is a gap between the stamp and the wall the die hole, even if it is extremely small. Such a gap can be detected by the optical pickup if sufficient brightness is available stands.
- the gap is displayed on a monitor so that the operator using the known adjustment device for the stamp so far adjusted that get a uniform gap width over the circumference becomes.
- the stamp is then attached to its sensor finally fixed, for example with the help of a suitable one Clamping device.
- the method according to the invention has further the advantage that a minimal game realizes can be without risk of collision with the Hole wall of the die comes.
- the device for performing the method sees one Lamp in front of the area between the stamp holder and Die off lights up.
- a ring lamp is provided for this purpose, which the stamp surrounds in the measuring position.
- the ring lamp can with the help suitable precautions temporarily mounted on the stamp with a suitable clamping device.
- an endoscope On the opposite side is the optical pickup arranged, for example formed by an endoscope can be.
- An endoscope has the advantage that it has relatively small dimensions and thereby in the Area between the die and the other press punches (lower punches) can be introduced.
- Fig. 1 shows part of a sinter press, namely one Die 10 in a corresponding receptacle 12 and one Upper stamp 14 in a corresponding recording 16. The associated lower stamp is not shown.
- the die 12 has a continuous one smooth-walled bore 18, the diameter of which is slight is larger than the outer diameter of the stamp 14. At coaxial alignment of bore 18 and punch 14 results a circumferentially extending gap of the width S.
- a section 20 of the stamp which is enlarged in diameter 14 lies over a plate 22 against the bottom of a recess 24 of the stamp holder 16.
- the Recess 24 dimensioned larger than the outer diameter of the Section 20.
- Threaded holes 26 formed (see also Fig. 2), can accommodate the set screws that match the section 20 interact.
- the one diametrically opposite Pair of screws can be adjusted in the X axis (Fig. 2) and with the diametrically opposite pair offset by 90 ° in the Z direction make.
- one Clamping plate 28 which surrounds the stamp 14 and against the Section 20 is applied, only slightly tightened (the clamping screws are indicated by dashed lines at 30).
- Fig. 3 it can be seen how the stamp 14 from a Ring 32 is surrounded, which is a ring lamp, the illuminates an area between ring 32 and stamp 14, as shown at 34.
- the stamp is similar to that in FIG Arranged in Fig. 3 shortly before immersion in the bore 18.
- the output of the camera 36 goes over a processing unit 39 on a monitor 40.
- the bore 18 added, largely shaded by the stamp 14 is with the exception of the gap S (Fig. 1).
- the operator can now see on the monitor 40 when this gap approximately over the circumference of the stamp has the same width.
- the stamp 14 in the manner described above transverse to it Axis can be adjusted until the gap is approximately even is.
