In the first stage of upward extension of the piston rod of the cylinder:
the movable seat moves upwards in the vertical direction and is far away from the supporting plate, so that one end of the first connecting rod and one end of the second connecting rod, which are connected with the pressure head, and one end of the rotating rod, which is connected with the middle part of the first connecting rod, are driven to rotate forwards until the first connecting rod is close to a vertical state and the rotating rod is close to a horizontal state, the pin shafts on the movable seat drive the 2 movable baffles to move upwards, and under the limiting action of the guide grooves and the guide convex strips, the movable baffles only move upwards on opposite side baffles in the vertical direction and further squeeze the springs;

In the second stage of the piston rod of the cylinder continuing to extend upwards:
the movable seat continues to move upwards for a small distance in the vertical direction until the stroke upper limit of the piston rod, in the process, the rear end of the pressure head rotates upwards under the action of the upper arch part of the movable seat, and the front end of the pressure head rotates downwards until the lower surface of the front end of the pressure head presses the workpiece;
when the front end of the pressure head rotates downwards, the floating baffle plate with the upper part embedded into the arc-shaped groove on the lower surface of the pressure head moves downwards for a small distance under the action of the pressure head and further compresses the spring, at this time, the floating baffle plate with the upper part still embedded into the arc-shaped groove is positioned at the lower part of the groove and the lower surface of the floating baffle plate is close to the lower wall of the groove
When the chip-proof CNC processing press claw is adopted, on the basis that the press head always maintains a nearly horizontal state and contracts back and forth to save space required by action and reduce adhesion of scraps, the press head can be locked without reverse overturning when being in a clamping state, so that stable and continuous pressure is maintained, and the defect that a workpiece is deviated or dithered due to loosening of pressure holding force in the processing process to cause a product is avoided; the side baffle plate, the front baffle plate, the movable baffle plate and the floating baffle plate are fixedly arranged, so that circumferential shielding of the whole compression process of the pressing claw is realized, adverse interference of chips generated in the processing process to the pressing claw is further avoided, and the bonding between the floating baffle plate and the lower surface of the pressing head is kept in order to prevent chips from flying into a shielding area in the whole process of pressing the workpiece slightly downwards after the pressing head upwards.
