The outer wall that collet 232 inserts cutting main shaft 231 interior section is provided with projection, projection comprises the first inclined-plane 232a, first inclined-plane 232a arranges towards push rod 2310 and reduces highly gradually, pushing sleeve 2311 is sleeved on the outer wall of push rod 2310 and collet 232 junction, and pushing sleeve 2311 and the first inclined-plane 232a are slided by inclined-plane and are connected, particularly, pushing sleeve 2311 is connected with the first inclined-plane 232a of projection, pushing sleeve 2311 and the end face that the first inclined-plane 232a connects are the inclined-plane contrary with the first inclined-plane 232a incline direction, the inclined-plane of pushing sleeve 2311 just can match with the first inclined-plane 232a and be connected.Under the driving of clamping cylinder 239, the promotion pushing sleeve 2311 of push rod 2310 supports to collet 232, and collet 232 is to central reduction clamping tubing, reduce the vibration of tubing, make pipe notch smooth, cutting blade is not easy to collapse cutter, increases cutting blade service life.The inclined-plane of pushing sleeve 2311 and coordinating of the first inclined-plane 232a, the more laborsaving clamping that can reach collet 232.
Projection also comprises the second inclined-plane 232b, second inclined-plane 232b arranges towards described cutting blade 237 and reduces highly gradually, blade part 23 also comprises chuck 232 positioning end cover being arranged at collet 232 outer wall, chuck 232 locating cover one end is fixed on cutting main shaft 231, and be connected by inclined-plane with the first inclined-plane 232a, particularly, chuck 232 locating cover and the end face that the second inclined-plane 232b connects are the inclined-plane contrary with the second inclined-plane 232b incline direction, and the inclined-plane of chuck 232 locating cover just can match with the second inclined-plane 232b and be connected.In the present embodiment, second inclined-plane 232b is approximately 90 ° relative to the axis of cutting main shaft 231, the inclined-plane of chuck 232 locating cover can ensure in chuck 232 clamping process with coordinating of the second inclined-plane 232b, reduce the axially-movable of chuck 232, the precision of chuck 232 axial location, thus the length accuracy ensureing incising pipes.
Control system receives the result that there is tubing in feeding clamping 222, then send the signal controlling feeding servomotor, the work of push broach cutting servomotor.In the present embodiment, in cutting process, cutting electric rotating machine 26 High Rotation Speed always.
Fixing clamping parts 25 are for clamping tubing, and fixing clamping parts 25 and chuck 232 lay respectively at the both sides of cutting blade 237.And fixing distance between clamping parts 25 and chuck 232 can be regulated by control system as required.In the present embodiment, fixing distance between clamping and chuck 232 is adjusted to the thickness being a bit larger tham cutting blade 237, like this, in tubing cutting process, due to chuck 232 and fixing clamping close together, cutting blade 237 cuts between chuck 232 and fixing clamping, the rigidity of support of tubing is good, tubing not easily vibrates, and cutting mouth of pipe quality is good, and cutting blade 237 also not easily collapses cutter.
See Fig. 8, fixing clamping is connected with the hopper 28 of inclination, and hopper 28 is provided with through hole 281 and turnover panel 282, and through hole 281 is for holding turnover panel 282, and turnover panel 282 is hinged on hopper 28, and the below of hopper 28 is provided with finished product collecting box and waste collection case.Feeding inductive switch is surveyed the length of well cutting tubing and is sent to control system, and when control system judges that the length of well cutting tubing is less than preset length value, turnover panel 282 is opened, and tubing falls into waste collection case along the through hole 281 on hopper 28; Otherwise turnover panel 282 is closed, tubing falls into product-collecting case along hopper 28, realizes the collection respectively to finished product and waste product, thus realizes finished product and be separated with the automatic of tailing.
In addition, before tubing cutting, whether cutting head material can be selected as required, and head material is sent in waste collection case.
Before tubing cutting, the preset length of pipe finished needed for inputting in the controls, the diameter of cutting blade 237, pipe diameter and wall thickness etc., control system controls the supplying position of cutting blade 237 incising pipes, convenient and swift.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure change, all still belong to the protection domain of technical solution of the present invention.
