It asks, can adapt to the Environmental Protection Situation currently got worse.
Meanwhile the notch of the cut out tubing of lathe of the present invention is smooth, the Incision temperature of Cold Extrusion Process will not increase, notch
Material is not hardened, and is easy to carry out secondary operation to tubing, solves the problems, such as traditional cutting technique cutting knife hardening.
Above-mentioned technical effect is mainly to be realized by technological improvement in detailed below:
Cutting process of the invention are as follows: tubing is passed through into cutting head and connector sleeve, in cutting, tubing is motionless, cutting head rotation,
Spiral rack gear is driven to radially move simultaneously, round cutter cuts off tubing by cold extrusion.Specific cutting process includes feed
Journey and withdrawing process, a feed process and a withdrawing process are a complete cutting process.
Main to complete following feed operations/acts link for feed process: 1) PLC control system controls motor up time
Needle rotation, driving small pulley rotation, small pulley drive big belt wheel by V-belt；2) big belt wheel is driven by connector sleeve and is cut
Head rotates clockwise；3) bevel pinion is together with bevel pinion as cutting head rotates clockwise；4) bevel pinion is as row
Star-wheel clockwise, is rotated around the auger ring gear as sun gear；5) bevel pinion is under the driving of bevel pinion
Rotation；6) the large helical gear rotation that bevel pinion driving is engaged with；7) large helical gear driving spiral bevel pinion rotation；8) snail
Bevel pinion driving spiral cone ring gear rotation is revolved, and driven spiral bevel pinion is driven to rotate；9) spiral bores ring gear driving and its
The spiral rack gear of engagement moves inwards along the radial direction of cutting head, drives cutter, squeeze to the round tube that need to be cut off and cut
It is disconnected.For in the link of the above feed process, link 3) to being 6) action process of drive gear set；Link 7) to 9) for transmission
The action process of gear set.It is described above merely to be described in detail feed process, be not to drive gear set, driving gear set structure
Specific restriction, any structure that can be realized gear set function is within the scope of the present invention.
For withdrawing process, following withdrawing operations/acts link is mainly completed: 1) when sensor detects that cutter has been cut
When disconnected tubing, PLC control system issues signal, and motor rotates counterclockwise, and cutting head is driven to do rotation counterclockwise；2) gear set
In drive gear set and driving gear set reversely rotate, spiral rack gear is displaced outwardly along the radial direction of cutting head, band
Dynamic cutter, the round tube far from cutting.
Heretofore described cutting head clockwise turns to feed process, rotates to be withdrawing process counterclockwise, only pair
The explanation of technical solution, rather than the restriction to technical solution bore the spiral direction of spiral straight-tooth on ring gear by changing spiral,
Corresponding relationship between i.e. changeable cutting head clockwise/anticlockwise rotation and forward/back blade process.
The present invention matched using bevel pinion and auger ring gear, the bevel pinion and big helical teeth of large helix angle cylinder helical teeth
Wheel cooperation is used as drive gear set, and gear driving is steady, and power output is powerful, and noise is small.
The plane spiral rack-and-pinion conduct that the present invention is formed using spiral bevel pinion, spiral cone ring gear, spiral rack gear
Driving gear set, this transmission system are very powerful to the reinforcement effect of cutter tip, and using a spiral bevel pinion, several
A driven spiral bevel pinion and spiral cone ring gear engage, and play the role of dynamic branch and dynamically stable, power transmission is more flat
It is suitable.
The present invention carries out cutting process automatic control using PLC control system, using the fixed tubing of pneumatic clamping mechanism, adopts
With pneumatic feed mechanism automatic feed, the length of incising pipes is adjustable, and size is accurate, can reduce the labor intensity of worker, operation
It is more convenient.
