After the press cutting is finished, the force application device is removed, the spring rebounds, and the press cutting device can automatically recover to the initial state.
The pressure head center is provided with step-like through-hole, and the stand of clamp plate upper end passes this through-hole, realizes the centering, and the upper end of spring is supported in the step position of through-hole.
The upper end of the pressure cutting rod is provided with a shaft shoulder, so that the axial positioning on the pressure head is realized, and the pressure cutting rod and the pressure head are in transition fit or interference fit, so that the pressure cutting rod is prevented from swinging.
The lower end of the pressure cutting rod is provided with a shaft shoulder to realize axial positioning on the pressing plate, and the lower end of the pressure cutting rod is provided with a sharp edge with a cutting effect.
The through hole at the lower end of the pressing plate is in small clearance fit with the pressing and cutting rod; ensuring smooth press cutting of the diaphragm.
The base through hole is in small clearance fit with the pressing and cutting rod, so that smooth pressing and cutting of the diaphragm can be guaranteed.
The pressure plate is also provided with a guide hole which is in small clearance fit with the guide rod.
The utility model has the advantages that: the problem of use punching tool die-cut one by one lead to the die-cut quality of diaphragm hole unstable, inefficiency is solved, the device is simple easily to be realized and application scope is extensive.

FIG. 1 is a schematic view of a film press cutting apparatus;
description of numbering: 1-pressure head, 2-pressure cutting rod, 3-pressure plate, 4-base, 5-lower nut, 6-diaphragm, 7-guide rod, 8-spring and 9-upper nut.
Detailed Description
As shown in fig. 1, a film press-cutting device; pressure head 1 is through the pressure cut pole 2, spring 8 and last nut 9 are connected with clamp plate 3, the fastening of pressure head 1 and pressure cut pole 2 is realized through the shoulder on the pressure cut pole 2 and last nut 9, the shaft hole cooperation through on pressure head 1 and the clamp plate 3 realizes the centering, spring 8 is in compression state, produce the holding power between pressure head 1 and clamp plate 3, pressure cut pole 2 carries on spacingly through the shoulder in 3 locating holes of clamp plate, make pressure head 1 and clamp plate 3 not throw off under the effect of supporting force. Guide bar 7 is connected with base 4 through lower nut 5, the fastening of base 4 and guide bar 7 is realized with lower nut 5 through the shaft shoulder on guide bar 7, lead to clamp plate 3 through guide bar 7 and the guiding hole on clamp plate 3, make diaphragm 6 when the crush-cutting, guarantee the centering of crush-cutting pole 2 and base 4 crush-cutting passageway, in the device, the mounting hole of crush-cutting pole 2, the through-hole that the clearing hole and be used for crush-cutting pole 2 to lead need to set up with the axle center, in order to guarantee the unimpeded of crush-cutting process.
