The one-way valve installed at the side of the box 64 close to the connecting pipe 66 is used for unidirectionally guiding the air outside the box 64 to the pumping area of the box 64.

[0061] When the sliding seat 24 moves to one end of the workbench 1, the second gear 62 in the blowing mechanism 6 located at the same end of the workbench 1 is respectively spaced apart from the third rack bar 67 and the second rack bar 61. The second gear 62 in the blowing mechanism 6 located at the other end of the workbench 1 is respectively in meshing transmission with the third rack bar 67 and the second rack bar 61.

The second gear 62 in the blowing mechanism 6 located at the left end of the workbench 1 is respectively in meshing transmission with the third rack bar 67 and the second rack bar 61.

[0062] When the rotating mechanism 2 finishes the work, the second hydraulic cylinder 52 is started, and the punching head 55 is driven by the second telescopic rod 53 to move towards the workbench 1, when the punching head 55 moves towards the workbench 1 to the maximum displacement, the end face of the punching head 55 away from the mounting base 54 is located in the lower die 56, and the required shape is punched from the plastic part plate, and the extrusion plate 63 in the blowing mechanism 6 at the other end of the workbench 1 is driven to slide along the inner wall of the box body 64 to the maximum displacement away from the workbench 1, and the gas in the pumping area in the box body 64 is transported to the blowing head 610 through the connecting pipe 66, so as to blow the idle polishing position area on the workbench 1, blow the punching debris and polishing residues left on the workbench 1 to the outside of the workbench 1, and ensure the cleanness of the workbench 1.

[0063] Working principle: before the punching processing, the sliding seat 24 is driven by the motor 21 to slide along the sliding groove 22 to the one end position of the workbench 1, at this time, one pair of clamping mechanisms 3 close to the same one end of the workbench 1 clamps and fixes the plastic part plate processed by punching and to be polished, and the lower surface of the plastic part plate located in the polishing position area is in frictional contact with the polishing surface of the polishing disc 47, and the other pair of clamping mechanisms 3 clamps and fixes the plastic part plate to be punched;

[0064] The second hydraulic cylinder 52 is started, the second telescopic rod 53 drives the punching head 55 to move towards the workbench 1 to the maximum displacement through the mounting base 54, so as to punch the plastic part plate to be punched in the punching position area, at the same time, the mounting base 54 drives the first rack rod 41 through the cantilever 49, so that the first rack rod 41 meshes with the first gear 42, and further meshes with the driving bevel gear 44 and the driven bevel gear 45, so that the polishing disc 47 rotates to polish the punching edge position of the plastic part plate, so that the punching processing and the deburring processing of the plastic part plate are carried out at the same time, the processing efficiency is greatly improved, and at the same time, the punching quality of the plate is ensured. During the movement of the punching head 55 away from the workbench 1 to the initial position, the polishing disc 47 rotates in the opposite direction, and continues to polish the punching edge position of the plastic part plate, so as to realize further repair after polishing;

[0065] Moreover, when the polishing work is carried out at the polishing position on one side, the polishing position on the other side of the punching position is in an idle state, and the second gear 62 in the blowing mechanism 6 at the same end of the workbench 1 as the slide 24 is spaced apart from the third rack bar 67 and the second rack bar 61, respectively, while the second gear 62 in the blowing mechanism 6 at the other end of the workbench 1 is in meshing transmission with the third rack bar 67 and the second rack bar 61, respectively. When the punching head 55 moves to the maximum displacement in the direction close to the workbench 1 to carry out the punching work, the cantilever 49 drives the second rack bar 61 to make the blowing mechanism 6 at the other end of the workbench 1 carry out the blowing work, specifically: the second rack bar 61 meshes and drives the second gear 62, and further meshes and drives the third rack bar 67 through the second gear 62, so that the extrusion plate 63 moves away from the workbench 1, and the gas in the pump area in the box 64 is transported to the blowing head 610 through the connecting pipe 66, so as to blow the workbench 1 table surface of the idle polishing position area, blow the polishing residues and punching debris to the outside of the workbench 1, ensure the neatness of the workbench 1 table surface, avoid the accumulation of debris, cause scratches on the surface of the plastic part plate during the polishing process, and affect the product processing quality.

[0066] After the above-mentioned punching work is completed, the polished plastic part plate is removed, and a new unprocessed plastic part plate is replaced, then under the reverse driving of the motor 21, the slide 24 reversely slides along the sliding groove 22 to the other end position of the workbench 1, moves the plastic part plate at the polishing position on one side to the punching position, and synchronously moves the punched plastic part plate at the punching position to the polishing position on the other side, to realize the automatic conversion of the punching work station and the polishing work station of the plastic part plate, improve the processing efficiency, and complete the punching work.
