After groove pipe fitting is cast out, flash can be formed in the opposite sides of pipe fitting along the die joint of mold, shown in Fig. 5
For elbow, the opposite sides of groove 40, the phase with 41 end of opposite sides and seal section of the seal section 41 of clip cooperation
Flash 42 can all occur to two sides, the flash 42 of above-mentioned position, the omission of other positions are illustrated only in figure.
Illustrate usage mode of the invention by taking elbow as an example below.Referring to Fig.1 and emphasis is referring to Fig. 4 and Fig. 5, by elbow
Through fixture clamping on workbench 21, starting emery wheel rotation, the relative positional relationship, that is, elbow and emery wheel of elbow and emery wheel
Realizing for contact, separation etc. can all be realized by the relative movement of workbench 21 and grinding power head 22.Make elbow one end
Side is close to the end of emery wheel, and elbow is also moved to emery wheel center simultaneously after which contacts with the abrasive material on emery wheel end
Dynamic, elbow is abraded to flash 42 of the emery wheel center during mobile on end face 43, sees step A in Fig. 4；The hair of end
While the seal section for grinding off rear elbow, which enters emery wheel, enters set in vivo, it can be by seal section one into the abrasive material on convex ribs in the process
The flash of side is ground off, and sees step B in Fig. 4；The flash of seal section side grinds off rear convex ribs and enters groove and groove side
Flash is ground off, and sees step C in Fig. 4；After the flash of groove side is ground off, convex ribs enter groove simultaneously the groove other side from the other side
Flash grind off, see step D in Fig. 4；After the flash of the groove other side is ground off, the seal section of elbow exits emery wheel, exits process
Abrasive material on middle convex ribs can grind off the flash of the seal section other side, see step E in Fig. 4；So far elbow one end flash removes
Process is completed.Rotary work-table 21 makes the other end of elbow enter grinding station, and other end flash can be carried out by repeating above-mentioned movement
Removal.When being ground flash in groove, the abrasive material 4 on the inner wall of body 2 can also refine seal section, Ke Yiti
The roundness of surface flatness and seal section at high sealing section flash.
It is above-mentioned only to illustrate usage mode of the invention by taking elbow as an example, it can also be to ditches such as threeway, four-ways using the present invention
Barrel part carries out flash removal, and this is no longer going to repeat them.
