Definitions

  • the invention relates to a shaft straightening and hardening machine with the features the preamble of claim 1.
  • the rotary drive carries the receptacle with the delivered directional and Counter-rolling through the coolant bath, usually an oil bath to deter the workpiece. After emerging from the oil bath, the hardened Workpiece after swiveling the straightening rollers out of the headstocks taken. On the other hand, it is also possible to gas the workpiece to deter (HTM 53 (1998), page 87 ff.).
  • the invention is based, with a wave direction and the task hardening machine of the type mentioned the delivery of the counter rollers at To simplify setting up the workpiece.
  • a second counter roller can be rotatably attached, the straightening device has a second straightening role.
  • This can be used for neighboring straightening points different workpiece diameter serve a single bearing, on the one end a counter-roller, for example, of smaller diameter and on its other opposite end of a counter roller of larger diameter can be plugged on.
  • the shaft straightening and hardening machine points first a tub 2 containing oil as a coolant and one in the tub in not shown rotatably mounted drum 4. Is on the two faces the drum 4 via a chain 5, 6 or the like with a rotary drive coupled. On the top of the drum 4 rising above the oil 3 sits in near the two end faces a headstock 10, 12, which on a bed 14 at the top of the drum 4 in the direction of the two double arrows 11, 13 is movable. Between the mutually facing grain tips 15, 17 is a wavy workpiece 20 and supported by at least one with one of the Headstocks 10, 12 coupled motor driven in rotation.
  • Straightening devices 22, 24, 26 at locations of the length of the workpiece 20 on the Bed 14 provided on which the workpiece 20 must be directed. These ones five straightening points are designated with 21, 23, 25, 27, 29.
  • Each straightening device 22 24, 26 usually consists of an upper leveling role and per leveling role a pair of lower counter rolls, the straightening roll and the associated Counter-rollers equally distributed radially in the circumferential direction apply according to the set pressure.
  • the drum 4th by the rotary drive, not shown, about a to the axis of the workpiece 20th parallel axis rotated that the warm, possibly red glowing workpiece 20 immersed in the oil and quenched there.
  • the shaft straightening and hardening machine 1 can in particular manipulate cylindrical workpieces 20, their sections in the axial direction have different diameters, i.e. they are graduated. So it owns workpiece 20 shown a first section 20a with a small diameter, an axially adjoining section 20b of medium diameter and one End section 20c with the largest diameter.
  • the straightening points 21, 23 are located at section 20a, the straightening points 25, 27 at section 20b and the straightening point 29 at section 20c.
  • a bearing block rises from a carriage 31 below section 20a 32, which is axially displaceable along the bed 14, but transversely to the axis of the Workpiece 20 is not movable.
  • the bearing block 32 is a free running Shaft mounted, the axis of which extends parallel to the axis of the workpiece 20 and their opposite ends 34, 36 laterally from the bearing block 32 protrude.
  • a counter roller 38 is attached to the end 34 of the shaft, for which purpose a tongue and groove arrangement 33, 35 between counter roller 38 and end 34 is used.
  • a counter roller 39 is on the opposite, free end 36 of the shaft attached in the same way in a rotationally fixed manner.
  • the diameter of each of the two Counter rollers 38, 39 is dimensioned such that each of the two counter rollers 38, 39 on the Periphery of the workpiece section 20a rests.
  • the straightening device 22 also includes an upper bearing block 42, which on one Vertical drive, not shown, is suspended and in accordance with arrow 41 can be advanced against the workpiece section 20a from above by the vertical drive.
  • the upper bearing block 42 has a shaft, not shown in detail, whose Axis extends parallel to the workpiece axis.
  • On the two opposite free ends 44, 46 of this shaft are each a straightening roller 48, 49 attached, which after delivery against the workpiece portion 20a on the Apply periphery from above.
  • the first Counter roller 38 a second counter roller 38a of the same diameter with groove and Spring arrangement 37, 39 between it and end 34a as the counter roller 38 belongs and on the free end 34a of a further shaft mounted in the bearing block 32 is rotatably attached.
  • the arrangement of the straightening roller 48 and the pair of Counter rollers 38, 38a are hit in the circumferential direction around the workpiece axis in such a way that the straightening rollers 38, 38a laterally touch the workpiece 20 from below, wherein the angle between the workpiece axis and the two axes of the free ends 34, 34a is symmetrical to the vertical and is, for example, 120 °.
  • the third is the same except for the differences below Straightening device 26 in its structural design and operating behavior first straightening device 22, so that reference to the above explanations can be taken.
  • the first difference is that only one of the two free ends of the shaft mounted in the bearing block 62, namely on the free end 64 a counter roller 68 is plugged on, the diameter again is smaller than the diameter of the counter roller 58.
  • the decrease in diameter corresponds exactly to the radial height of the shoulder between the Workpiece sections 20b and 20c. Accordingly, the upper one points to one Vertical drive suspended bracket 72 also only a straightening roller 78, which against the workpiece section 20c is fed from above.
  • the Counter roller 68 belongs to a similar counter roller 68a, which according to FIG.
  • the former is opposite with respect to the vertical through the workpiece axis. Further 2 that the centers of the counter rollers 38, 39, 58, 59 and 68 lie on a common imaginary line that is parallel to Extends workpiece axis. The centers of the counter rollers 38a, 68a are corresponding and the counter rollers belonging to the counter rollers 58 and 59 and 39, respectively same diameter also on an imaginary line that is parallel to the Extends workpiece axis.
  • the straightening device 24 can be omitted and the straightening device 22 so far along the workpiece axis on the bed 14 that the straightening roller 38 on the workpiece section 20a and the Straightening roller 39 abuts the workpiece section 20b, so that the radial shoulder between the workpiece sections 20a and 20b between the straightening rollers 38 and 39 is located.
  • the diameter of the straightening roller 39 is of course then equal to the diameter of the straightening roller 58, so that in this case the on the opposite free ends 34 and 36 respectively Straightening rollers 38 and 39 have different diameters.
  • the invention also enables the processing of Workpieces which, for example, carry a gear wheel 50 which extends radially far out. In this case, it is only necessary that the gear wheel 50 on each side a straightening device 24 and 26 is provided.
  • each of the bearing blocks 32, 52, 62 one rotary drive each for the associated counter rollers 38, 39 or 58, 59 or 68 housed so that a drive of the grain tips 15, 17 can be omitted.
