Definitions
- the invention relates to a device for deep rolling of recesses and radii on crankshafts after Features of the preamble of the main claim.
- Crankshafts are deep-rolled with the help of Deep rolling rollers, which with a predetermined force in the Punctures and radii are pressed, which affect the bearings limit a crankshaft laterally.
- a machine or tools for deep rolling of the radii and recesses of crankshafts known for example from EP 0 683 012 A1 and from EP 0 661 137 B1 and EP 0 299 111 B1. Both known method is known Machines can be rotated using the deep rolling tool the deep rolling rollers of the material of the crankshafts plasticized to a depth of about 1 mm.
- DE 195 11 882 A1 describes a method for Solidification of workpiece surfaces has become known.
- the known method is also based on the Crankshaft machining applicable.
- the Workpiece surface during the hardening process metrologically recorded and from the measurement results Standard values for setting / changing Tool parameters derived.
- the Penetration depth of the deforming tool Workpiece surface detected.
- One with one the corresponding pressing force of the deep rolling roller penetrates the material and creates depending on the Flow behavior of the workpiece material poses on both sides of the penetrating deep rolling roller.
- the actual depth of penetration of the deep rolling roller results then from the difference of the poses.
- the In terms of measurement technology the surface contour itself is varied Way are recorded mechanically, for example, pneumatic, hydraulic, acoustic, electromagnetic, electrocapacitive or electronic by means of acting sensor.
- the indirect method is disadvantageous in the known method Detect the depth of penetration on both sides of the poses the penetrating deep rolling roller. Such poses are sometimes nonexistent or so little pronounced that they are hardly recorded by measurement can. This is particularly the case with the Posing at the transitions on either side of Punctures on crankshafts, which in each case different levels. That's enough there Experience demonstrated the accuracy with which the poses can not be measured to be reliable Statements about the depth of penetration of the deep rolling roller into the To make crankshaft. It is much cheaper instead which is to follow the path of the deep rolling roller directly it in the radial, be it in the axial direction of movement in Regarding the crankshaft or both Directions of movement at the same time.
- Deep rolling rolls of a machine a shorter one compared to the other deep rolling rolls Have standing time and fail prematurely. With the so far known means is such a premature one Failure of the deep rolling tool difficult or at all not to be discovered.
- the industry has therefore so far Use it to randomly sample the rolled radii or punctures of crankshafts using measuring pliers control that are created by hand.
- a measuring tool used which is constructed identically as a Rolling tool. Be under a low investment force before the actual start of the deep rolling operation Measuring rollers inserted into the punctures of the bearing points. The axial spreading of the penetration Measuring rollers are recorded and used as a measurement for the quality of the Preprocessing determined.
- sensors serve the axial distance between individual measuring rollers and neighboring ones Detect oil bundles on the crankshaft.
- the device can use such a method single deep rolling roller of a deep rolling tool perform, but it can also result Penetration depth of both deep rolling rollers, which one Deep rolling tool usually has to be measured.
- the resulting axial displacement of the Measuring rollers of a measuring tool are recorded.
- To measure the depth of penetration of the deep rolling rollers or the displacement the measuring rollers of a measuring tool in the axial direction are several facilities, their special Selection in the area of the measures of the relevant specialist.
- the penetration depths measured with the help of sensors Deep rolling rollers of a deep rolling tool respectively Displacements of the measuring rollers of a measuring tool fed to a computer, stored in the computer, in Calculated quantities are converted and then the Fixed rolling force regulated. This is usually how you do it before that the crankshaft before the actual one Deep rolling initially with a low and constant Application force rolls and after deep rolling under the Deep rolling force forms the difference between the measured values from the depths of penetration under the landing force and the Deep rolling force results and then based on a corresponding calculated calculation size determines the penetration depth.
- a such a calculation size is advantageously suitable for Errors that occur during the pre-machining of the crankshaft it by machining, be it by hardening or due to damage to the deep rolling rollers themselves determine.
