Single tubing on the motion pre-determined distance of feed mechanism 1 (being here 180mm), the gripping wheel holding mechanism 16 of feeding clamping 222, servo
Single tubing is transported in the chuck 232 of blade part 23, so by screw mandrel under the accurate guiding of feeding line slideway 223
When can reduce backgauge feeding distribution mechanism 15 and transmitting single tubing to wheel holding mechanism 16, the requirement to single tubing front and back position.
Referring to Fig. 5, including cutting main shaft 231, the inside of cutting main shaft 231 along cutting main shaft 231 it is axially arranged have be used for
The chuck 232 of tubing is clamped, the outside of cutting main shaft 231 is exposed in one end of chuck 232, and one end of cutting main shaft 231 is arranged rotation
It is fixed with pivoted housing 233, the end face of rotary sleeve 233 on cutterhead 234, cutterhead 234 and knife block 235 and support wheel sliding block is housed
236, the end face of knife block 235 and support wheel sliding block 236 away from cutting main shaft 231 is inclined-plane, and knife block 235 passes through axle
Connection cutting blade 237 is held, cutting blade 237 is used to cut off tubing, and 236 pieces of skidding of support connects back-up roller wheel by bearing
238, back-up roller wheel 238 is used to support tubing.The end of chuck 232 towards cutting blade 237 is to expose to cut the outer of main shaft 231
Portion.
It is respectively connected with by sliding outer cover 241 with knife block 235, support wheel sliding block 236, driving knife block 235 is pushed away
Dynamic cutting blade 237 is moved to tubing center, and driving support wheel sliding block 236 promotes back-up roller wheel 238 to be moved to tubing center
It is dynamic.Referring to Fig. 6, in the present embodiment, push broach cutting part 24 includes sliding outer cover 241, push broach cutting servomotor, and push broach is cut
Cut servo screw mandrel 242, push broach line slideway 243, push broach frame 244 and push broach wheel 245.Referring to Fig. 7, sliding outer cover 241 is set in
The outside of rotary sleeve 233, the inwall of sliding outer cover 241 connects with the inclined-plane of knife block 235 and the inclined-plane of support wheel sliding block 236
Touch, under the guiding respectively on the inclined-plane of knife block 235 and the inclined-plane of support wheel sliding block 236, the pressing knife block of sliding outer cover 241
235 and support wheel sliding block 236 to tubing center move.It is sliding connection, branch between knife block 235 and cutterhead 234
It is also sliding connection between support wheel sliding block 236 and cutterhead 234, so, under the extruding of sliding outer cover 241, blade is slided
Block 235 is just moved with support wheel sliding block 236 towards tubing center.
In the present embodiment, knife block 235, support wheel sliding block 236, cutting blade 237 and back-up roller wheel 238 are
The right side of cutterhead is arranged on, in incising pipes, sliding outer cover 241 advances to the right, i.e., is transported towards the direction of cutting blade 237
Dynamic, because the face that knife block 235 contact with the inwall of sliding outer cover 241 is inclined-plane, and chamfer length can be arranged as required to, cunning
Inclined-plane or cambered surface of the dynamic inwall of overcoat 241 with face that knife block 235 is in contact to be engaged with knife block 235.Support wheel
The face that sliding block 236 is contacted with the inwall of sliding outer cover 241 is also inclined-plane, and chamfer length can be arranged as required to, sliding outer cover 241
The face that inwall and support wheel sliding block 236 are in contact is the inclined-plane or cambered surface being engaged with support wheel sliding block 236.In the present embodiment
In, the length on the inclined-plane of knife block 235 is less than the chamfer length of support wheel sliding block 236, so, in incising pipes, cutter
Piece 237 can be moved towards tubing center always, until cut-out tubing.And support wheel sliding block 236 touches pipe in back-up roller wheel 238
During material outer wall, then stop moving to tubing center.
Cutting main shaft 231 push broach cutting servo screw mandrel 242 cuts servomotor with push broach and push broach frame 244 is connected, and pushes away
