After the material clamping hydraulic rod 402 is started, it can drive the clamping plate 403 to move, so as to achieve the purpose of clamping the material. While clamping the material, the pressure sensor 405 will be driven by the material into the installation detection groove 406 through the installation spring 404.

After the material clamping hydraulic rod 402 is started, the clamping plate 403 is driven to move, so as to achieve the purpose of clamping the material. While clamping the material, the pressure sensor 405 will be driven by the material into the installation detection groove 406 through the installation spring 404. At the same time, the pressure sensor 405 immediately stops the material clamping hydraulic rod 402 from clamping the material through the servo control component 6, so as to achieve the purpose of automatically clamping materials of different sizes without damaging the material.

[0032] Step three: By setting up a servo motor 303, the servo motor 303 can drive the rotating threaded shaft 301 to rotate under the movable fixation of the press mounting frame 1. The rotating threaded shaft 301 and the threaded groove 302 are threadedly connected. At this time, the rotating threaded shaft 301 can drive the auxiliary substrate 207 to move through the threaded groove 302, so as to achieve the purpose of precise press-fitting trigger position adjustment, which is convenient for adapting to materials of different press-fitting sizes. By setting up a guide rod 7 and a sliding sleeve 8, when the auxiliary substrate 207 moves, the guide rod 7 will also slide in the sliding sleeve 8, so as to achieve the purpose of vertical movement of the auxiliary substrate 207.

[0033] Step 4: When the material pressing assembly 5 is pressed to the set distance, pressure is applied to the buffer contact plate 203, and the buffer contact plate 203 transmits the pressure to the trigger buffer rod 202.

[0034] Working principle: By setting the installation groove 201, the purpose of slidably installing the trigger buffer rod 202 is achieved. When the material pressing component 5 is pressed to the set distance, pressure is applied to the buffer contact plate 203, and the buffer contact plate 203 transmits the pressure to the trigger buffer rod 202. At this time, the trigger buffer rod 202 and the buffer mounting plate 204 move, so that the buffer damper 205 and the buffer spring 206 can double buffer the trigger pressure of the buffer mounting plate 204 and the trigger buffer rod 202, and triple buffer is performed by the buffer sponge pad 209, so as to reduce the impact force of the material fixing component 4 and avoid damage to the trigger switch 208.

At this time, the rotating threaded shaft 301 can drive the auxiliary substrate 207 to move through the thread groove 302, so as to achieve the purpose of accurate press-fitting trigger position adjustment, which is convenient for adapting to materials of different press-fitting sizes. By setting the guide rod 7 and the sliding sleeve 8, when the auxiliary substrate 207 moves, the guide rod 7 will also slide in the sliding sleeve 8, so as to achieve the purpose of vertical movement of the auxiliary substrate 207. During press-fitting, the material is first placed on the press-fitting machine mounting frame 1, and then the material clamping hydraulic rod 402 is started to fix the material clamping hydraulic rod 402. By setting the material clamping mounting frame 401, the material clamping hydraulic rod 402 is conveniently fixed.

While clamping the material, the pressure sensor 405 is driven by the material into the installation detection groove 406 through the installation spring 404. At the same time, the pressure sensor 405 immediately stops the material clamping hydraulic rod 402 from clamping the material through the servo control component 6, thereby automatically clamping materials of different sizes without damaging the materials. By setting the press-fitting column 501, the purpose of facilitating the vertical sliding of the press-fitting mounting plate 502 and supporting the hydraulic cylinder fixing frame 504 is achieved. The servo hydraulic cylinder 503 is controlled by the servo control component 6 to drive the press-fitting mounting plate 502 to move, thereby achieving the purpose of automatically press-fitting the material; By setting up the control mounting frame 601, the purpose of facilitating the installation of the servo controller 602, the PLC controller 603 and the PLC touch screen 604 is achieved, the servo controller 602 is made to facilitate the control of the servo hydraulic cylinder 503 for precise pressing, the PLC controller 603 and the PLC touch screen 604 are made to set the pressing distance, and the movable universal wheel 9 is provided to achieve the purpose of making the pressing machine movable.
