Detailed description of the invention
In Fig. 1, Fig. 2, a kind of efficient thread rolling device, comprise drive end bearing bracket 2, slip cap 3, milled head 4, rear end cap 5, thread rolling apparatus 18 and power input shaft 9, the medial surface of the slip cap 3 below the turning rolls 19 of described thread rolling apparatus 18 is provided with an inclined plane groove 17, in inclined plane groove 17, be provided with adjustment pad 16, have adjustment locknut 6 in the arranged outside of rear end cap 5.In figure, 1 is processing work, and 14 is axially move core spring bearing, and 20 is turning rolls springs, and 21 is frames.
The inner side of rear end cap 5 is provided with a cutter lining 7, described cutter lining 7 is provided with the cutter lining locating hole 8 set up vertical with power input shaft 9, radial dynamic core 10 is provided with in a cutter lining locating hole 8, axially dynamic core 12 is provided with inside the line shaft 9 that described radial direction is moved below core 10, described axis is moved core 12 front end and is provided with inclined-plane feather key 22, move in core 10 in radial direction the inclined-plane chute 23 (see Fig. 3, Fig. 4) being provided with and matching with inclined-plane feather key 22, above a cutter lining 7, be provided with wheel 13 device of returning sword; A cutter spring 15 is provided with between milled head 4 and rear end cap 5.The arranged outside moving core 10 in radial direction has back-moving spring 11.
Be provided with in the inner side of power input shaft 9 and move core fixing hole 24 with the axis that axially dynamic core 12 inclined-plane card key 22 matches, described in state axially dynamic core 12 and be flexibly connected with power input shaft 9 by inclined-plane card key 22 and fixing hole 23.
Wheel apparatus 13 of returning sword is made up of bearing 31 of returning sword, return sword wheel shaft 32 and wheel 33 of returning sword, described in wheel 33 of returning sword be arranged on by wheel shaft 32 of returning sword and return sword on bearing 31.
Described thread rolling apparatus 18 is cylindrical die roll or billmpse tool, outer circle roller, circular cone roller, and number of cutters is more than three or three.
The power set of described adjustment locknut 6 are pneumatic, hydraulic pressure or electric device.
Operation principle of the present invention is: drive rear end cap 5 advance or retreat by rotating adjustment locknut 6, thus slip cap 3 is moved forward and backward, slip cap 3 inside is provided with a taper seat, this taper seat move axially by compressing or loosen outer cone adjustment pad 16, make it to move radially, drive turning rolls 19 and cylindrical die roll 18, thus change the radial size apart from axis of 3 cylindrical die rolls, reach the object of adjustment processing dimension.After workpiece is clamped by jaw, thread rolling apparatus rotates and along workpiece axial feed, cylindrical die roll 18 pairs of surface of the works carry out rolling screw-threads, and form screw thread.When thread rolling apparatus advances to that axially dynamic core 12 touches workpiece front end face, axially dynamic core 12 is stopped by workpiece 1 and stops, and thread rolling apparatus continues to move forward, make the inclined-plane feather key 22 of axially dynamic core 12 rear end press down the radial direction coordinated with it and move inclined-plane chute in core 10, radial dynamic core 10 moves along workpiece radial direction to the center of circle, finally deviate from from a cutter lining locating hole 8, now, cutter spring 15 promotes rear end cap 5 and drives slip cap 3 to move backward, turning rolls spring 20 pops up and turning rolls 19, cylindrical die roll 18 is pushed away workpiece thread surface, completes a cutter action.Exit moving after thread rolling apparatus, rear end cap 5 touches wheel 33 of returning sword to be stopped, and when milled head 4 continues back to initial position, back-moving spring 11 promotes radial dynamic core 10 and reenters reset (see Fig. 5) in a cutter lining locating hole 8.
The control (see Fig. 6) to work pieces process length dimension is realized by the mode changing axially dynamic core length.Processing work can be the material of the various ways such as pole, reinforcing bar, pipe, cone.
