Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the Cold knocking machine for multiple keys providing the present invention is described in detail.
Embodiment
With reference to Fig. 1-Fig. 3, the Cold knocking machine for multiple keys of the present embodiment, including support 17, fuselage 18, main transmission and
Support fixture 8, it also includes mair motor 14, X-axis motor 1, Z axis motor 5, two roll main shafts 7, rolls 6
With workpiece drive system, said two roll main shaft 7 is symmetrically installed, and two roll main shafts 7 are respectively provided with one
Roll 6, described support fixture 8 is positioned on the centrage of two roll main shafts 7, support fixture 8 has clamped work
Part 16.Described main transmission includes B through-drive chain 12, B through-drive chain 12 one end and top part mair motor 14
Connecting, the other end is connected with roll main shaft 7.Cold knocking machine for multiple keys also includes X-axis driving-chain 2 and feed screw nut 3,
Described X-axis motor 1, X-axis driving-chain 2, feed screw nut 3, roll main shaft 7 are sequentially connected with.Described workpiece transmission
System includes workpiece interrupted division movement transmission and workpiece linear reciprocating motion drive system, workpiece interrupted division
Movement transmission includes indexing mechanism driving-chain 13 and indexing mechanism 9, described mair motor 14, indexing mechanism transmission
Chain 13, indexing mechanism 9 and support fixture 8 are sequentially connected with.Described workpiece linear reciprocating motion drive system includes Z

It is connected.
Cold knocking machine for multiple keys realizes the cold forming that strikes of workpiece by following drive motion: 1, first mair motor energising is revolved
Turning, and pass motion to B through-drive chain, B through-drive chain drives two roll main shafts to reversely rotate, two rolls
The reverse rotation of main shaft drives again two rolls to reversely rotate, and roll realizes each around the rotary motion of center roll main shaft；
2, roll also has reciprocal circular motion while roll main shaft rotates, and X-axis electrical power rotates, and will rotate
Moving through X-axis driving-chain and pass to feed screw nut, feed screw nut drives two roll main shafts to do reversely around central shaft 15
Reciprocal circular motion, thus drive the roll on roll main shaft to do the most reciprocal circular motion；3, processed workpiece,
Doing interrupted division motion and linear reciprocating motion under the drive of mair motor and Z axis motor, mair motor rotates also simultaneously
Passing motion to indexing mechanism by indexing mechanism driving-chain, indexing mechanism drives workpiece to rotate and does dividing movement,
When workpiece is in indexing intermittent condition, Z axis motor drives ball-screw to move by Z-axis transmission chain, ball wire
Thick stick drives slide to seesaw on fuselage, thus drives the workpiece on slide to seesaw.Do reverse circumference reciprocal
The roll of motion, when moving to the position with absorption surface, owing to two rolls self are around the reverse rotation of roll main shaft
Motion, workpiece is tapped while contacting with surface of the work by roll relatively, during tapping, roll master
Axle circumferentially track rotates a circle, and drives roll to tap workpiece once, and workpiece does axle under Z axis driven by motor simultaneously
After feed motion, percussion, workpiece indexes once under the drive of indexing mechanism.
Cold knocking machine for multiple keys, working (machining) efficiency is high, relatively conventional metals cutting technology, can improve efficiency 20～30 times；
By two rolls, workpiece being carried out beatening repeatedly, do not produce chip, metal structure is fine and closely woven, the bending of workpiece
Intensity, fatigue strength dramatically increase, the good combination property of gained part, and the life-span can improve 2～3 times；Save material,
Cold percussion is material for transfer rather than excision material, and compared with traditional machining process, teeth portion can save material
20%～40%, reduce production cost.
Cold knocking machine for multiple keys applied range, can be widely applied to the various bigger specification profile of tooth on axle class, disk-like accessory
Processing, as truck drive shaft spline, automobile clutch tooth hub spline and other various moduluses are not more than 3.5mm
Involute spline.
