Definitions

  • the machine for forming threads on bolts, and the like blanks by means of thread rolling tools comprises a frame, a thread rolling tool movable in the frame of the machine, said rolling tool being reciprocal along a cooperating stationary rolling tool mounted on a holding means in the frame, means for adjusting the holding means and the stationary tool; in vertical direction with respect to the direction of reciprocation of the movable tool so as to obtain the desired pitch of the screwthread on the blank; in a transverse direction perpendicular to the direction of the reciprocation so as to obtain the desired diameter of the screwthread on the blank; and in an inclined position in order to provide for the same diameter over the entire length of the threads on the blank.
  • the holding means in the form of a block is provided with a cleft substantially in its longitudinal direction parallel to the direction of movement of the reciprocable rolling tool, said cleft ending at its bottom in a slit-shaped bore also extending in said longitudinal direction, said holding means being provided at its topside with a groove opening into said cleft, and an adjusting member in the groove for controlling the width of said groove.
  • the present invention relates to a device for providing bolts and the like with screwthread by means of flat rolling tools, comprising a rolling tool movable in the frame of the device, said rolling tool being reciprocable along a rolling tool that is stationary in a holding means in the frame, said holding means being adapted to be adjusted in vertical direction with regard to the direction of reciprocation so as to obtain the right pitch of the screwthread, and in transverse direction perpendicularly to the direction of reciprocation so as to obtain the right diameter of the screwthread and in an inclined position in order to provide for the same diameter over the entire length of the screwthread.
  • the holding means is provided in its longitudinal direction parallel to the direction of movement of the reciprocable rolling tool, with a cleft ending at its bottom side in a slitshaped bore also extending in its longitudinal direction, and is provided at its topside with a groove in which an adjustable member is provided for controlling the width of said groove.
  • the groove in the topside of the holding means has at least one hollow side wall extending conically and in said groove a wedge which is adjustable in longitudinal direction is provided, the shape of said wedge being adapted to the shape of said groove.
  • the means for carrying into effect the right diameter of the screwthread exist of at least two adjacent adjustable wedges positioned between the holding means and the frame of the device.
  • the preferably vertically adjustable wedges are transversely curved at the side of the holding means, said curved sides cooperating with correspondingly curved parts of the holding means.
  • FIG. 1 shows a side elevation of a prior art machine with a partial cross-section along the line I-I in FIG. 2 of the important portion of the known machine.
  • FIG. 2 shows a cross-section of the prior art machine along the line iI-ll in FIG. 1.
  • FIG. 3 shows a plan view of the important portion of the embodiment according to the invention.
  • FIG. 4 shows a vertical cross-section along the line lV-lV in FIG. 3.
  • FIG. 5 shows a vertical section along the line V-V in FIG. 3.
  • FIG. 6 shows a side elevation of the holding means of the stationary roller.
  • FIG. 7 shows a plan view of the holding means of the stationary roller.
  • the reciprocable, non-adjustable screwthread roller 11 is also fastened in the carriage 12 which is adapted to carry out a reciprocable movement in a known manner by means of a connecting rod 17.
  • the stationary roller block 2 is adjustably fastened in the holding means I in the frame 22 by means of clamping members 20, 21.
  • Said holding means 1 in the form of a block, (FIGS. 6 and 7) is provided over its entire length parallel to the direction of movement of the reciprocable screwthread roller 11 with a longitudinal cleft 23 extending into or ending at the bottom side as seen in FIG. 6 in a slitshaped bore 24. Furthermore said holding means 1 is provided at its topside with a ball-shaped groove 25 having a arcuate-shaped sides, an adjusting wedge 26 adapted to the shape of the groove 25, said wedge being lengthwise adjustable by means of an adjusting bolt 27 as seen in FIG. 3.
  • roller member 2 will spread out more at its topside than at its bottom side so that said roller member 2 will be placed more or less inclined.
  • adjusting wedges 28 and 29 which are adapted to adjust the holding means 1 forwardly and backwardly by means of adjusting bolts 30 and 31.
  • Said adjusting wedges 28 and 29 together form a supporting surface that is sufficiently large, so that a maladjustment by the formation of pits is not possible.
  • the holding means 1 needs only to be fastened by a single bolt 32. Besides the fact that said bolt 32 pulls the holding means 1, with the insertion of the two adjusting wedges 28 and 29, against the frame 22, said holding means 1 is also pressed downwardly onto the frame 22 by the conical shape of said adjusting wedges 28 and 29, said two wedges and 16 being positioned for that purpose underneath said screwthread roller in the frame 22.
  • the adjusting operation of the device according to the present invention takes place as follows.
  • the adjusting wedge 15 underneath the holding means 1 is adjusted lengthwise by means of the bolt 33, so that the holding means 1 is adjusted vertically.
