Definitions
- the invention relates to a device for calibrating a sintered molded part with a helical toothing with a calibration tool, comprising a lower punch for receiving the sintered shaped part with a lower punch external teeth, a vertically movable and axially rotatably supported Oberstempel Oberstempelau presentverzahnung, and an axially rotatably supported die with a Matrizeninnenverzahnung and a method for calibrating a sintered molded part with a helical toothing with a calibration tool, comprising a lower punch with a lower punch external toothing, a vertically movable and axially rotatably supported Oberstempel with Oberstkovau builtverzahnung, as well as an axially rotatably supported die with a Matrizeninnenverzahnung, after which the sintered molding is placed on the lower punch and positioned on this, then the upper punch is lowered in the direction of the sintered molding and thereby the sintered molding and the Unt occidentalkov be lowered in the
- US Pat. No. 7,025,929 B discloses a method for recompressing the teeth of a toothed wheel with a helical toothing. For this purpose, after the powder has been compacted and then sintered, it is pressed with a punch through a die which has a toothing complementary to the toothed wheel on the inner surface. By pushing through the near-surface areas of the teeth are further compressed. The gear is moved only by axial, helical movement through the die. The die has a plurality of sub-matrices, which are separated by cutting discs.
- DE 698 22 572 T2 describes a device for adjusting the size of the tooth profiles of helical gears, comprising: a lower punch, wherein a gear blank having teeth formed thereon is adapted to be placed thereon, an upper punching means which is vertically movable to press down the gear blank and a sizing measure adapted to engage inner peripheral teeth thereof with the gear blank pressed by the upper punch to adjust the tooth profiles of the gear blank in size.
- the lower punch has a first and a second lower punch, with the second lower punch punched thereto.
- the first lower punch is axially rotatable about the second lower punch and has outer peripheral teeth thereon, the size setting dimension being axially rotatable and vertically movable while its inner peripheral teeth are engaged with the outer peripheral teeth of the first lower punch, and wherein the upper punching means is axially rotatable and provided with outer peripheral teeth, which engage with inner peripheral teeth of the size setting scale.
- this DE-T2 describes a method for adjusting the size of tooth profiles of helical gears after a gear blank having teeth formed thereon is non-rotatably positioned on a lower punch, then the size of the tooth profiles of the gear blank by pressing the gear blank downward with an upper one Punching means is set in a sizing dimension, while the teeth of the gear blank and outer peripheral teeth of the upper punching means with inner peripheral teeth of the size setting scale are engaged and - at the completion of the size setting step - the size adjustment from the engagement with the upper punching means and the gear blank by turning and lowering the discoursetelltimeform and moving the upper punching means is released upward and the gear blank is removed.
- the advantage here is that the movement of the tool can be simplified by the exclusively vertical mobility of the lower punch, in which an additional Liehe drive device for a rotary movement of the lower punch, as is known from the prior art, can be dispensed with. It is also easier to carry out the storage of the die, since the discharge of the finished calibrated sintered component is carried out by an upward movement of the lower punch. As a result, it is possible to control the feeding and discharging conditions of the sintered component to and from the tool easier to do, since the supply of the blank takes place on a plane or at the same height as the discharge of the finished calibrated sintered component. It is thus easier to carry out an automation of the device or the method for calibrating a sintered molded part. In addition, no additional masses must be moved vertically, so that the energy balance of the device turns out cheaper.
- the die is exclusively rotatably supported, whereby an additional drive means for lowering the die, as it is known and necessary from the prior art for the demolding of the sintered molded part, can be dispensed with, whereby a further simplification the device is enabled.
- the upper punch of the calibration tool can be operatively connected to a guide unit which sets the upper punch in a rotational movement during the calibration process of the sintered shaped part in the matrix, whereby a relative movement between the workpiece and the upper punch during calibration is avoided.
- the lower punch or the upper punch can form the drive device for the axial rotational movement of the die, whereby an additional drive device for this can be dispensed with and moreover the synchronization of the movement of the die with the movement of the lower punch or of the upper punch is easier to carry out.
- the rotational movement of the die can in this case be carried out by lowering the upper punch or the lower punch as a result of the engagement of the respective outer toothing with the inner toothing of the die.
- an axial rotation of the upper punch is initiated even before the impact of the upper punch on the sintered molding or the blank, wherein the engagement position of the outer toothing of the upper punch is made in the internal toothing of the die by this rotation. It will achieved with that the upper punch can be moved from any relative position to the die automatically in the engaged position, so that an additional vote of the movement of the upper punch and this synchronization movement does not have to be made.
- the upper punch after lowering the sintered molded part on a contact surface of the die together with the lower punch by the upper punch does not rotate axially, so by moving together of the upper punch with the lower punch an entire compression of the sintered compact over its cross section - in axial Direction - is bidirectional, so not only a calibration of the teeth is feasible with the inventive method, but at the same time also the said total compression. It can thus be carried out with a single device, both the calibration and the compression of the molded part blank.
