The below describes operation principle and the flow process of the present embodiment take the knife blade that two straight lines of a grinding add the circular arc cutting edge as example:
1. start, electric control system sends instruction by program, starts grinding head motor 14 band emery wheel 2 High Rotation Speeds, and clamping cylinder 6 makes the relative tool post 4 of pressing plate 5 of flying knife seat mechanism be in relaxation state, and other mechanism is in initial position.
2. referring to Fig. 1, be under relaxation state at the relative tool post 4 of pressing plate 5 of flying knife seat mechanism, the knife blade 1 that two straight lines is added the circular arc cutting edge is sent between pressing plate 5 and tool post 4, and is located by the location structure on tool post 4.Electric control system sends instruction by program, makes the drop-down pressing plate 5 of clamping cylinder 6 compress simultaneously two knife blades 1.The knife blade 1 that under impaction state, two straight lines add the circular arc cutting edge is overlooked under state as shown in Figure 4, and this moment, two knife blades 1 were back-to-back, and the path of cutting edge is a straight line paragraph, an arc section and a straightway successively.
3. after two knife blade 1 clampings were completed, electric control system sent instruction by program, and propulsion cylinder 19 promotes to advance the left side of slides 18 along the first moving sets to Fig. 6 to move, and made emery wheel 2 be advanced to knife blade 1 cutting edge position and carried out grinding.At this moment, the 3rd controls motor 25 promotes to advance support plate 17 to move (Y-direction in Fig. 1 moves) along three moving sets by the 3rd screw-nut body 26, thereby force the cutting edge moving linearly of emery wheel 2 relative knife blades 1, realize the grinding for the first time of first paragraph straight line edge section.Then, the 3rd controls motor 25 stops operating, and make the cutting edge of emery wheel 2 relative knife blades 1 stop rectilinear motion, and the control of the revolution in flying knife seat mechanism motor 8 begins to rotate, make the relative emery wheel 2 of cutting edge of knife blade 1 do circular motion, realize the grinding for the first time of second segment circular arc cutting edge section.Then, revolution is controlled motor 8 and is stopped operating, and changes the 3rd control motor 25 over to and continues to begin to rotate, and makes the cutting edge moving linearly of emery wheel 2 relative knife blades 1, realizes the grinding for the first time of the 3rd section straight line edge section.When after grinding is completed for the first time of the 3rd section straight line edge section, second controls motor 21 drives the relative knife blades 1 of emery wheel 2 by the second screw-nut body 22 and does feed motion.Then, the 3rd controls motor 25 reverses and passes through the 3rd screw-nut body 26 promotion propelling support plates 17 along three moving sets to phase shift, makes the cutting edge of emery wheel 2 relative knife blades 1 do the reverse linear motion, realizes the grinding for the second time of the 3rd section straight line edge section.Then, the 3rd controls motor 25 stops operating, make the cutting edge of emery wheel 2 relative knife blades 1 stop anti-phase rectilinear motion, and motor 8 beginning backward rotation are controlled in the revolution in the flying knife seat mechanism, make the relative emery wheel 2 of cutting edge of knife blade 1 do reverse circular motion, realize the grinding for the second time of second segment circular arc cutting edge section.Then, revolution is controlled motor 8 and is stopped operating, and changes the 3rd over to and controls motor 25 continuation beginning backward rotation, makes the cutting edge of emery wheel 2 relative knife blades 1 do the reverse linear motion, realizes the grinding for the second time of first paragraph straight line edge section.The automatic grinding track of whole knife blade 1 cutting edge as shown in Figure 5.Knife blade cutting edge secondary Principle of Grinding and Cutting is seen Fig. 7, and what Fig. 7 represented is the situation of grinding for the first time, and hatching represents stock removal for the second time.
4. after two knife blade 1 grinding edges are completed, propulsion cylinder 19 promotes to advance the right side of slides 18 along the first moving sets to Fig. 6 to move, and makes emery wheel 2 return to starting bit and puts, and prepare to enter grinding next time.At this moment, clamping cylinder 6 moves and goes up push plate 5, makes the relative tool post 4 of pressing plate 5 be in relaxation state, can take out two knife blades 1 under this state.
5. repeat above process, complete the automatic grinding to the operation blade cutting edge.
Can find out from above operation principle and flow process description, first, the present embodiment not only can once be completed the automatic grinding that two straight lines add Circular Nose Cutting Edge operation on mouth blade 1, also can once complete the automatic grinding of two Circular Nose Cutting Edge operation on mouth blades, perhaps once complete the automatic grinding of two straight line edge knife blades, the difference just control of program is adjusted accordingly.The second, the present embodiment not only can once be completed the automatic grinding of two operation blade cutting edges, also can be used for once completing the automatic grinding of leader's art blade cutting edge.The 3rd, the present embodiment not only can adopt secondary sharpening mode to realize to knife blade, also can adopt a sharpening mode to realize.
