Description
Technical field
The present invention relates to cutting processing equipment field, specifically a kind of metal tube cutter device, especially a kind of thin-walled
Undeformed metal tube cutter device.
Background technique
Abrasive wheel cutting machine is a kind of extensive process equipment of use.Although cheap, easy to operate, in cutting gold
Since metal tube rigidity is low when belonging to pipe fitting, grinding wheel weak heat-dissipating in cutting process easily makes the notch of metal tube generate necking
With burr flash, and cut the contracted length generated up to 1/5th of caliber, necking down up to caliber 1/10th.
Application No. is 201410324463.3 documents to disclose a kind of thin-wall pipe diced system, which passes through
Cylinder piston rod drives locating rod movement to clamp to pipe fitting, has multiple axial heat release holes on cutterhead；But it should
Diced system can only treat cutting pipes and be clamped, and cannot clamp to excision part, so that cut point offset generates
Burr flash；And the motionless unidirectional cutting centripetal force for being subject to same cut point of the cutting pipes and waste heat are larger, to produce
Raw biggish necking；And the heat release hole on cutterhead in axial direction is conducive to radiate, but does not radiate to blade directly, heat dissipation effect
Difference.
Summary of the invention
In view of the deficiencies of the prior art, the technical issues of present invention intends to solve is to provide a kind of metal tube cutter device.
The technical solution that the present invention solves the technical problem is to provide a kind of metal tube cutter device, and feature exists
In the cutter device include cutting mechanism, the first clamp system, the second clamp system, feed mechanism and rack；
The rack includes upper flange, lower wing plate and side plate；The upper flange and lower wing plate are fixed on the two sides of side plate；Side
Location hole is provided on plate, for passing through for metal tube；The notch communicated with location hole is provided on side plate, for cutting mechanism
The reciprocating motion of transmission shaft；The cutting mechanism is for cutting metal tube；The feed mechanism is for driving cutting mechanism real
Now move back and forth；
First clamp system includes two-way lead screw, support, second base and clamping section；The second base is fixed on
On upper flange；Support is fixed in second base；The two-way lead screw may be rotatably mounted on support；The spiral shell of two-way lead screw two sides
Line part is threaded with clamping section respectively；
Second clamp system includes pivoting support bearing, triangular fixing frame, clamps block teeth, is connecting column, fulcrum bearing, small
Gear, locking stud, latch segment, the second motor, swinging plate, positioning stud and bolt；The fulcrum bearing is fixed on lower wing plate；
The inner ring of pivoting support bearing is fixedly connected with fulcrum bearing；Several connecting columns are uniformly fixed on outside pivoting support bearing by bolt
On the end face of circle；Connecting column sequentially passes through the kidney slot of respective swinging plate, clamps the through-hole of block teeth and the peace of triangular fixing frame
Dress hole simultaneously realizes that swinging plate, clamping block teeth and triangular fixing frame are installed in connecting column by the head of bolt, the waist of swinging plate
Shape hole can be realized rotation of the swinging plate relative to connecting column, and clamping block teeth can rotate relative to respective connecting column；The folder
One end of tight block teeth is buckled on swinging plate, and the other end is used for the clamping of metal tube；Second motor is fixed on fulcrum bearing
On, the pinion gear engaged with the outer ring of pivoting support bearing is fixed on output shaft；The latch segment can by positioning stud
It is rotatably installed on the end face of pivoting support bearing outer ring, latch segment can be rotated relative to positioning stud；The locking stud spiral shell
Line is mounted on latch segment, and the one end for locking stud can be contacted with swinging plate.
Compared with prior art, the beneficial effects of the invention are that:
1, metal tube is made to make rotating motion always by the second clamp system in cutting process, the cutting on metal tube
Point ceaselessly converts in carrying out circumferential movement, slows down same cut point since notch thermal deformation and unidirectional cutting centripetal force are made
At necking and burr flash phenomenon, reduce pipe fitting incision damage, improve cutting accuracy.
2, metal tube is only retained around central axis by the combination clamping mode of the first clamp system and the second clamp system
The freedom degree of rotation, and cutting sheet cuts metal tube between the first clamp system and the second clamp system, makes metal tube
Part will not generate circular runout, be conducive to improve metal tube and cut off stability of the part in cutting process, to improve gold
The cut quality for belonging to pipe fitting, further improves cutting accuracy.
3, radial through-hole is all had on cutting sheet and transmission shaft, in cutting sheet high speed rotation, due to internal-and external diameter linear speed
Degree is different, so that the both ends air pressure of cutting sheet internal-and external diameter is differently formed draught head, air flows in the through-hole of cutting sheet, is conducive to cut
Pitch cutting heat dissipation and the thermal decay for slowing down cutting sheet；And the through-hole leads to blade, can directly radiate to blade, improves
Radiating rate, extends the service life of cutting sheet.
4, since the first clamp system is mounted on the rack the lower surface of wing plate, two turning rolls form downward opening,
Metal tube is able to achieve the quick blanking for cutting off part after completing cutting；And metal tube to be cut is still pressed from both sides by the second clamp system
Tightly, the position that need to only adjust metal tube can carry out continuing to cut, and improve cutting efficiency.
5, due to the blocking of framework lateral plate, the chip for cutting generation will not have an impact the movement of cutting mechanism.
