[0029] At first, the transmission frame 54 squeezes the two push rods 82, and the two push rods 82 support the limit rod 63, the tension spring 65 is stretched, and the worker places the diaphragm 601 between the two guide plates 61, so that the diaphragm 601 contacts the upper side of the placement ring frame 62 and the center position of the diaphragm 601 is aligned with the center of the circle of the placement ring frame 62. Then the worker starts the electric push rod 3 and the drive motor 56, and the output shaft of the drive motor 56 drives the cutting head 561 to rotate, and the telescopic rod of the electric push rod 3 extends to drive the ring 4, the rotating ring 53, the transmission frame 54, the extrusion bar 57, the extrusion frame 71 and the spiral frame 81 to move downward, the push rod 82 separates from the transmission frame 54, and the tension spring 65 rebounds to drive the limit rod 63, the pressing ring 64 and the push rod 82 to move downward, and the extrusion bar 57 moves downward to extrude the mounting frame 55, the driving motor 56 and the cutting head 561, the two high-speed rotating cutting heads 561 move in a direction close to each other, the extrusion frame 71 moves downward to extrude the limit frame 72, the connecting frame 73 and the round rod 74 to move, the telescopic rod of the electric push rod 3 continues to extend to drive the circular ring 4, the rotating ring 53, the transmission frame 54, the extrusion bar 57, the extrusion frame 71 and the spiral frame 81 to move downward, and then the pressing ring 64 contacts the upper side of the diaphragm 601, the pressing ring 64 and the placing ring frame 62 clamp the diaphragm 601 together, the tension spring 65 no longer drives the limit rod 63, the pressing ring 64 and the pushing rod 82 to move downward, and then the round rod 74 contacts the upper side of the limit rod 63, and the round rod 74 squeezes the limit rod 63 and the pressing ring 64 The pressure limit makes the pressing ring 64 and the placing ring frame 62 more fully clamp the diaphragm 601, and the extrusion frame 71 moves downward and no longer squeezes the limit frame 72, the connecting frame 73 and the round rod 74 to move, and then the two high-speed rotating cutting heads 561 move in a direction close to each other to cut the diaphragm 601. After the cutting head 561 cuts the diaphragm 601 for a certain distance, the extrusion bar 57 moves downward and no longer squeezes the installation frame 55, the driving motor 56 and the cutting head 561 move, and then the pushing rod 82 contacts the spiral part of the guide groove on the spiral frame 81, and the telescopic rod of the electric push rod 3 continues to extend to drive the circular ring 4, the rotating ring 53, the transmission frame 54, the extrusion bar 57, the extrusion frame 71 and the spiral frame 81 to move downward, and the pushing rod 82 squeezes The spiral frame 81, the limiting ring 51, the guide frame 52, the rotating ring 53, the transmission frame 54, the mounting frame 55, the driving motor 56, the cutting head 561 and the extrusion strip 57 rotate half a circle, and the two cutting heads 561 rotate half a circle to complete the cutting of the diaphragm 601. When the pressing ring 64 and the placing ring frame 62 fully clamp the diaphragm 601 and limit it, the cutting head 561 cuts the diaphragm 601 around the edges of the pressing ring 64 and the placing ring frame 62, thereby reducing the deviation of the diaphragm 601 during the cutting process, thereby making the shape of the diaphragm 601 more complete after the cutting is completed, and the part of the diaphragm 601 that needs to be retained can be supported during the cutting process, thereby preventing the part of the diaphragm 601 that needs to be retained from being squeezed and deformed, thereby improving the cutting quality of the diaphragm 601.Finally, the worker controls the telescopic rod of the electric push rod 3 to contract and drive the circular ring 4, the rotating ring 53, the transmission frame 54, the extrusion bar 57, the extrusion frame 71 and the spiral frame 81 to move upward and reset, and the push rod 82 squeezes the spiral frame 81, the limit ring 51, the guide frame 52, the rotating ring 53, the transmission frame 54, the installation frame 55, the drive motor 56, the cutting head 561 and the extrusion bar 57 to rotate half a circle in the opposite direction to reset, and then the extrusion bar 57 moves upward to squeeze the installation frame 55, the drive motor 56 and the cutting head 561 to move in the opposite direction to reset, and the extrusion frame 71 moves upward to squeeze the limit frame 72, the connecting frame 73 and the round rod 74 to move in the opposite direction to reset, and the round rod 74 no longer squeezes the limit rod 63, and finally the transmission frame 54 squeezes the push rod 82 and the pressing ring 64 to move upward and reset, the tension spring 65 is compressed again, and the pressing ring 64 is separated from the diaphragm 601, and then the worker takes out the cut diaphragm 601 and the scraps, and finally the worker turns off the electric push rod 3 and the drive motor 56.

[0030] Initially, the worker introduces coolant into the guide tube 802, and the coolant flows out through the guide tube 802 and falls on the position where the cutting head 561 contacts the diaphragm 601, cooling the cutting position of the diaphragm 601 and reducing the deformation of the diaphragm 601 caused by the high temperature during the cutting process.

At this time, the cutting head 561 and the diaphragm 601 need to be partially separated. The extrusion frame 71 continues to move upward to drive the spring sheet 94, the lifting frame 91 and the grinding ring 93 to move upward, the return spring 911 is stretched, and the grinding ring 93 and the diaphragm 601 are separated. 01 needs to keep part of the edge contact, then the lifting frame 91 contacts the protrusion 92, the extrusion frame 71 continues to move upward, the spring sheet 94 is deformed, and the return spring 911 rebounds to drive the spring sheet 94, the lifting frame 91 and the grinding ring 93 to move downward and reset. During the up and down movement of the grinding ring 93, the grinding ring 93 grinds the edge of the diaphragm 601 that needs to be retained, thereby reducing the burrs on the edge of the diaphragm 601 that needs to be retained, and then making the edge of the diaphragm 601 that needs to be retained smoother.

[0033] Embodiment 3: Based on embodiment 2, Figure 2 , Figure 4 and Figure 5 As shown, it also includes a push block 101 and a return spring 102. Four push blocks 101 are slidably connected to the pressing ring 64, and two return springs 102 are connected between the four push blocks 101 and the pressing ring 64 through hooks.

[0034] When the tension spring 65 rebounds and drives the limit rod 63, the pressing ring 64 and the pushing rod 82 to move downward, the pressing ring 64 drives the pushing block 101 to move downward, and the pushing block 101 contacts the upper side of the diaphragm 601, and then the pressing ring 64 continues to move downward, and the pressing ring 64 squeezes the four pushing blocks 101 to move towards each other, and the four pushing blocks 101 contact the protrusions on the diaphragm 601 and push the diaphragm 601, so that the center position of the diaphragm 601 is aligned with the center of the circle of the placing ring frame 62, and then the pressing ring 64 and the placing ring frame 62 clamp the diaphragm 601 together, so that the accuracy of the cutting position of the diaphragm 601 can be improved.
