Description
Technical field
The utility model is related to a kind of fixture and its pipe cutting machines.
Background technology
Pipe cutting machine has both cutting pipe and its processes hollow out or the function of trepanning on required pipe, usually by whole
Long tubing is clamped on pipe cutting machine, is then sent into cutting cabinet by the tool sharpening in cutting cabinet and cutting, specifically for one section one section
As shown in Figure 1 and Figure 2,3 tail end of profile material tube is clipped in the chuck (chuck or three chucking chuck) on pipe cutting machine slide 4,
Cutting cabinet 1 is stretched into the head of profile material tube 3 by fixing chuck 6 (chuck 6 is installed on fuselage 2, and fuselage 2 is connected with cutting cabinet), by cutting
The tool sharpening in cabinet 1 and cutting are cut, is cut off after often processing one section of finished product, then profile material tube 3 is as slide 4 is to fixing card
Disk 6 moves, to which cutting cabinet is stretched into for processing and cutting in the head of profile material tube 3 again, until whole profile material tube 3 has been cut.
There are one drawbacks above, as shown in Fig. 2, as cutting carries out, 3 length of profile material tube is shorter and shorter, finally, profile material tube
After 3 have been cut soon, slide 4, which is moved to, is close to 6 side wall of chuck (or being close to 1 side wall of cutting cabinet), due to the thickness of fixed chuck 6
D is spent, the feeding cutting cabinet internal cutting of profile material tube 3 (can not possibly be had one by slide 4 between the cutting tool and chuck in cutting cabinet completely
Segment distance), namely last 3 federation of profile material tube leaves length and is at least one section of D and cannot use and waste, and is given birth in industrial mass
During production, every profile material tube 3, which finally can all leave one section, to be used, and cause prodigious waste in this way.
