Screw thread process technology, i.e., at ambient temperature, the work of screw tap rib tooth is passed through on prefabricated workpiece bottom outlet using thread forming tap
With causing metal to produce Plastic Flow, so as to form the technical process of internal thread.Internal thread cold-extrusion shaping causes internal thread to produce
Surface quality, dimensional accuracy, stock utilization and the mechanical performance of product are better than traditional internal thread machining mode, in cold extrusion
Screw thread has been above the internal thread processed with traditional approach in physical properties such as tensile strength, fatigue behaviour, case hardnesses, and it is
The important component of antifatigue process technology.But the moment of torsion that thread forming tap is born in Cold Extrusion Process is larger, thus
Easily thread forming tap is caused to be broken, larger resistance of deformation can be produced by being extruded workpiece, to the material of thread forming tap, structure and be added
Work makes and proposes higher requirement.And vibration machining technology is incorporated into stainless steel trapezoidal internal thread cold extrusion process
In, reduce thread forming tap rib tooth with the frictional force between workpiece bottom outlet material using the advantage of vibration machining to reach, so as to reach
To the effect for reducing extrusion torque and reduction thread forming tap abrasion.The country is still without the lathe that can realize above process.
The content of the invention
The purpose of the present invention is to produce the special of low-frequency vibration because lacking for the processing of existing Cold Forming of Internal Thread and set

The internal thread low frequency exciting cold extrusion Special Purpose Machine for Processing of processing efficiency and quality can be improved.
The technical scheme is that：
A kind of internal thread low frequency exciting cold extrusion Special Purpose Machine for Processing, it includes base 1 and main shaft 7, it is characterized in that described
Base 1 on be tiltedly installed with three root posts 2, three root posts 2 are distributed in equilateral triangle, and peace is fixed in the upper end of three root posts 2
Equipped with crossbeam 3, bottom plate 4 is vertically installed with crossbeam 3, longitudinal rail 5 and servomotor 8, longitudinal rail 5 are installed on bottom plate 4
On slide plate 6 is installed, servomotor 8 drives slide plate 6 to be moved up and down along longitudinal rail 5 by screw-nut body, and main shaft 7 is installed
On slide plate 6；Chuck 10 for clamping workpiece is provided with workbench 9, and workbench 9 is fixed on base 1 and stood positioned at three
The center position for the equilateral triangle that post 2 is surrounded；The upper end of described main shaft 7, which is provided with, can swash its generation low frequency revolution
The swing arm 12 shaken, swing arm 12 by column 2 auxiliary vibration device 11 driving make it is forward and reverse swing so that main shaft 7 produces
Circumferential controllable low-frequency vibration.
The angle of described column 2 and base 1 is 70-80 degree.
Identical auxiliary vibration device 11 is mounted on three described root posts 2, each auxiliary vibration device 11 is all provided with
There are two identical cam mechanisms, each cam mechanism is connected by respective connecting rod with the swing arm 12 on main shaft, three auxiliary
Three torsional oscillation collective effects eliminate eccentric torque caused by vibrating device 11, so as to improve the stability of lathe.
Described three root posts 2, base 1 and crossbeam 3 is connected to form integral vertical type structure.
Described column 2 uses the casting of casting（Nodular cast iron or gray cast iron）, crossbeam 3 is using honeycomb piece steel（Q
Series structure steel）.
Described crossbeam 3 is fixedly linked by countersunk head self threading pin and the upper end of column 2.
Beneficial effects of the present invention：
The tilted-putted triangle structure of three root posts of the present invention, can improve lathe integral rigidity, particularly work as
Apply ancillary vibration in process（Torsional oscillation）When, on the one hand because auxiliary vibration device is distributed on more root posts, can balance
Eccentric torque caused by single torsional oscillation, so as to ensure machine stability；On the other hand, relative to single column and double pillar constructions,
List column and double columns are deformed when three pillar constructions can effectively prevent from applying torsional oscillation, cause torsional oscillation not to be delivered to effectively
On main shaft；It in addition, three auxiliary vibration devices are distributed on three root posts, can cooperate, swing arm be applied sufficiently large with frequency
Moment of torsion, fully meet requirement of the processing to moment of torsion.
The auxiliary vibration device of the present invention is simple in construction, and applying mode is reliable, frequency and adjustable amplitude.
The ancillary vibration cold extrusion processing of the achievable different size different materials of the present invention, substantially increases workpieces processing
Surface quality and fatigue resistance, ancillary vibration can reduce thread forming tap rib tooth with the frictional force between workpiece bottom outlet material, from
And reach the effect for reducing extrusion torque and reducing thread forming tap abrasion.
