Definitions

  • the invention relates to a shaft straightening and hardening machine, with a receptacle for a wave-shaped workpiece, which is about a to the axis of the workpiece in substantially parallel axis is rotatably supported with a controlled Rotary drive for the recording and a coolant bath, which the recording traverses on part of their rotation path, as well as with at least one on one predetermined position of the length of the workpiece arranged straightening means, which the workpiece is loaded radially and for loading and unloading the workpiece from are pivotable.
  • This relatively selective straightening of the workpiece can then lead to one lead to undesired impairment of the workpiece if there is one or there are several axial, possibly also eccentric bores.
  • the invention aims to improve this type of machine.
  • the manufacture of the Straightening means by appropriate profiling of the straightening shafts outside the The machine is simplified when several points are aligned along the workpiece should be. Only one set of straightening shafts is used for a certain type of workpiece needed, which are clamped once in the pedestals and there independently of workpiece changes remain. For those mentioned, with one or more Workpieces provided with axial bores then prove to be the invention Particularly advantageous if the profiles have a relatively large axial width.
  • Shaft straightening and hardening machine first has a trough 2 containing oil 3 as Coolant and a rotatably mounted in the tub in a manner not shown Drum 4 on. At the two end faces, the drum 4 is over one each Chain 5, 6 or the like coupled with a rotary drive. On the about that Oil 3 uprising top of the drum 4 sit near the two end faces one headstock 10, 12 each on a bed 14 at the top of the drum 4th are displaceable in the direction of the two double arrows 11, 13. Between Grain tips 15, 17 facing one another are in the known machine 1 a wave-shaped workpiece 20 stored and at least one with a the headstocks 10, 12 coupled motor driven in rotation.
  • Each Straightening roll group 22, 24, 26, 28 usually consists of three straightening rolls, which are in The workpiece 20 is evenly distributed radially according to the circumferential direction apply the set pressure.
  • the known shaft straightening and hardening machine 1 shows the Recording by the headstocks 10, 12 and the associated center points 15, 17 formed, the top straightening rollers each for inserting the workpiece 20 Straightening roller pair must be pivoted radially.
  • the guide for that Workpiece 20 clearly forms the straightening roller groups 22, 24, 26, 28.
  • a receptacle 50 for a wave-shaped workpiece 30 made of three parallel alignment shafts 42, 44, 46.
  • Each of the straightening shafts 42, 44, 46 is on the end face in each case as a center point trained straightening shaft gripper held axially immovable, namely the first Straightening shaft 42 between center points 41 and 43, the second straightening shaft 44 between the grain tips 45 and 47 and the third directional shaft 46 between the Grain tips 49 and 51 (Fig. 4).
  • Each center of the grain is from a bearing block before, namely the center point 41 from the bearing block 52, the center point 43 the bearing block 54, the center point 55 from the bearing block 56, the center point 47 from the bearing block 58, the center point 49 from the bearing block 60 and finally the center point 51 from the bearing block 62.
  • the for receiving the Directional shafts 42 and 44 provided bearing blocks 52, 54 and 56 and 58 are on the bed of the shaft straightening and hardening machine, not shown below (For example on the bed 14 of Figure 1) firmly attached.
  • the pedestals 60 and 62 are each mounted on a swivel arm 61, 63, which on the Drum pivotable about an axis parallel to the axis of the alignment shaft 46 are articulated.
  • controllable Moving means housed, which allow the grain tips 43, 47, 51 axially to move translationally.
  • the grain tips 43, 47, 51 can therefore by Moving means are moved sideways so far that the straightening shafts 42, 44, 46 between the grain tips intended for them by not shown hoist can be inserted or removed.
  • the straightening shafts 42, 44, 46 in any case rotatably with the driven one Grain tip 41, 45, 49 connected, the respectively opposite Grain tips 43, 47, 51 are provided with the required rotary freewheel.
  • the swivel arms 61, 63 3 and 4 are pivoted so that the directional shaft 46 of the two non-pivotable straightening shafts 42, 44 can be lifted sufficiently far the workpiece 30 in the gap between the two by the aforementioned hoist Straightening shafts 42, 44 according to FIG. 3 are introduced.
  • the top one Straightening shaft 46 lowered so that the tool 30 of the three straightening shafts 42, 44, 46 is captured according to Figure 2 and radially by corresponding actuation of the Arms 61, 63 can be acted upon by the desired directional pressure.
  • each straightening shaft 42, 44, 46 a radial on each end face has protruding collar, which is designated for the directional shaft 46 with 37, 39, so that the workpiece 30 captured between the collars 37, 39 axially defined remains.
  • the straightening means in the invention are corresponding profiles of the jacket each of the directional shafts 42, 44, 46.
  • the directional shaft 42 is on one workpiece-specific preselected location, a first radially projecting alignment ring 32 worked out, the workpiece 30 at the desired location immediately acted upon. Over another area of the workpiece length, one is relatively wider Rich ring 34 is formed, and the end portion of the workpiece 30 is through contacted a third alignment ring 46 of the alignment shaft 42.
  • the directional shafts 42, 44, 46 as long as between the associated Grain tips can remain clamped like workpieces of the same type to be aligned and hardened. As long as the type of workpiece 30 remains the same, no further adjustment is required on the machine, it is sufficient that insert warm workpiece 30 into receptacle 50, receptacle 50 too close to turn the drum so that the straightening shafts 42, 44, 46 with Walk workpiece 30 in the desired manner through the oil bath and then by opening the receptacle 50, the workpiece 30 is closed again from the receptacle 50 remove.
