The sleeve 7 can slide upward into the corresponding opening of the rectangular tube 26, and a box body 8 is provided at the bottom end of the sleeve 7. The box body 8 is driven by an electric push rod 19, and a baffle 10 is provided at the top of the box body 8 to seal the bottom opening of the sleeve 7, wherein a rotating shaft 11 embedded in the inner wall of the box body 8 is provided at one end of the baffle 10, and a support rod 12 is provided in the box body 8 directly below the other end of the baffle 10;

[0026] A demoulding mechanism 13 is provided on the top of the machine 1 on both sides of the frame 4, and the demoulding mechanism 13 includes a top plate 131 located on the outside of the bottom plate 21, the top of the top plate 131 is lower than the horizontal plane of the top of the protrusion 27, and one end of the top plate 131 extends to the top of the bottom plate 21 outside the corresponding rectangular tube 26. An electric push rod II132 connected with the output shaft and the other end of the top plate 131 is provided in the machine 1.

[0027] like Figure 4 As shown, a blade portion is provided at the bottom of the outer wall of the punch head 3, a receiving groove 14 is provided in the middle of the bottom end of the punch head 3, a perforated plate 15 is provided at the bottom opening of the receiving groove 14, and the perforated plate 15 is connected to the top wall of the receiving groove 14 through a spring 16. An air duct 17 connected to the top of the receiving groove 14 is also provided in the side wall of the punch head 3, and the air duct 17 is connected to the exhaust fan through a hose.

[0028] like Figure 5 As shown, the support rod 12 is located directly below the two ends of the corresponding baffle 10, and the rotating shaft 11 is arranged on both sides of the end of the baffle 10 away from the sleeve 7. The bottom end of the sleeve 7 extends into the box body 8, and the bottom end of the sleeve 7 is flush with the top wall of the box body 8.

[0029] like Figure 3 As shown, the slide 23 is arranged in the middle of the length direction of the bottom of the base plate 21 , and there are two groups of slides 23 . The slides 23 are provided with screw holes that are screwed to the screw rods 24 . The mounting opening 6 and the box body 8 are located between the two groups of slides 23 .

[0030] In this embodiment, bearings (not shown in the figure) are provided on the inner wall of the machine 1 to fix the two ends of the screw rod 24, a toothed disc (not shown in the figure) is provided at the end of the screw rod 24, and a gear (not shown in the figure) meshing with the toothed disc is provided on the toothed disc, and the output shaft of the motor 25 is fixedly connected to the gear.

[0031] like Figure 1 As shown, the straight line formed by the protrusions 27 on both sides of the rectangular tube 26 is arranged parallel to the bottom plate 21 , and the straight line formed by the top plates 131 corresponding to both sides of the rectangular tube 26 is arranged perpendicularly to the bottom plate 21 .

[0032] Working principle: the motor 25 reverses and drives the screw rod 24 to rotate in the screw hole in the slide seat 23 through the gear and the toothed disk, thereby driving the slide seat 23 to slide in the sliding opening 22 and driving the bottom plate 21 to move, so that the bottom plate 21 drives the plurality of rectangular tubes 26 to move to one side of the frame 4. At this time, the bottom plate 21 slides on the bottom of the top plate 131 to prevent the top plate 131 from affecting the left and right displacement of the bottom plate 21, or there is no need to drive the screw rod 24, the slide seat 23 and the bottom plate 21 through the motor 25 to move. In the above two cases, only a plurality of sets of magnetic head shells are sequentially buckled on the rectangular tube 26 on one side of the frame 4, and the shell is fixed by the rectangular tube 26 to prevent it from moving horizontally. At the same time, the bottom of the shell is supported by the protrusions 27 on both sides to make it suspended. Then, when the bottom plate 21 drives the shell to move through the rectangular tube 26, the bottom of the shell that moves left and right is located above the top plate 131, so that the top plate 131 will not press against the bottom end of the shell and affect its horizontal displacement.

[0033] Then the motor 25 rotates forward through the gear and the toothed disk to drive the screw rod 24 to rotate in the screw hole in the slide 23, thereby driving the slide 23 to slide in the sliding opening 22 and driving the bottom plate 21 to move. At this time, the bottom plate 21 drives the rectangular tube 26 with the magnetic head shell buckled on it to move in sequence to the position directly below the punching head 3 and directly above the installation opening 6. Then the electric push rod I9 drives the box body 8 to drive the sleeve 7 to pass through the installation opening 6 and insert it into the rectangular tube 26. At the same time, the top of the sleeve 7 is against the inner top wall of the shell, and then the sleeve 7 and the rectangular tube 26 support the top wall outside the stamping opening at the top of the shell, and the sleeve 7 made of the electromagnet is energized to generate magnetic attraction to magnetically move the shell The baffle 10 is fixed to the top of the rectangular tube 26 and the sleeve 7 to prevent it from horizontal displacement or up and down movement during the subsequent processing, so as to improve the subsequent processing effect. When the sleeve 7 made of the electromagnet material works, it will exert a certain upward suction on the baffle 10, so that the baffle 10 in an inclined state with one end resting on the support rod 12 will rotate with the rotating shaft 11 as the center of the circle, and finally one end of the baffle 10 is magnetically connected and fixed to the bottom end surface of the sleeve 7, so that the two groups of baffles 10 are finally in a horizontal state to seal the bottom opening of the sleeve 7, so as to prevent the subsequent sleeve 7 from generating a magnetic suction force when it continues to work, which will cause the metal debris that may be stored in the box body 8 to move up and be adsorbed on the end surface of the sleeve 7;

[0034] In the above process, since the sleeve 7 is inserted into the rectangular tube 26, the fixture 2 can be further fixed to prevent the base plate 21, the rectangular tube 26 and the shell from moving due to factors such as the subsequent malfunction of the motor 25, and then the subsequent punch head 3 cannot effectively punch the shell. After the sleeve 7 is inserted into the rectangular tube 26 to magnetically fix its top shell, the hydraulic rod 5 drives the punch head 3 to move downward to punch holes in the top wall of the shell, and then its bottom end slides into the top of the sleeve 7. In this process, the debris obtained by punching can directly fall into the sleeve 7 and be adsorbed on its inner wall under the influence of magnetic attraction, or slide into the receiving groove 14 to push the orifice plate 15 to squeeze the spring 16. When the spring 16 is compressed to a certain extent, it stretches and pushes the orifice plate 15 downward, thereby pushing the The debris moves downward and finally slides into the sleeve 7, so that the debris is finally magnetically attracted to the inner wall of the sleeve 7. In the above process, the internal opening of the sleeve 7 is larger than the diameter of the punch head 3, so that the punch head 3 can slide in and the debris can fall into it without being stuck. At the same time, the high-pressure cold air flow can be forced into the receiving groove 14 through the exhaust fan, hose and air duct 17 to flow downward from the aperture of the orifice plate 15, so as to cool the side wall of the punch head 3 and blow the metal debris that may remain inside into the sleeve 7 and magnetically attract it to its inner wall, so as to realize the debris cleaning work. In the above process, an exhaust pipe with a diameter of not more than 0.5 cm can be set at the bottom of the sleeve 7 for the discharge of the introduced gas to prevent the pressure in the sleeve 7. At the same time, filters are set at the openings at both ends of the exhaust pipe to prevent the metal debris in the sleeve 7 from being discharged;

[0035] After the punch head 3 moves up and resets, the electric push rod I9 drives the box body 8 to drive the sleeve 7 to move down to be drawn out from the rectangular tube 26. At this time, the sleeve 7 is powered off and stops working. Then, under the influence of its magnetic attraction, the baffle 10 rotates with the rotating shaft 11 as the center under the influence of gravity. Finally, the baffle 10 tilts and rests on the support rod 12, so that an inverted eight-shaped structure is formed between the two groups of baffles 10. At this time, the impurities on the inner wall of the sleeve 7 fall on the two groups of baffles 10 under the influence of the magnetic attraction, and then flow into the box body 8 below the baffle 10 along its inclined surface for temporary storage. At the same time, after the work is completed, or when there are a lot of debris in the box body 8, the slag discharge pipe at the bottom can be opened to discharge;

[0036] After the sleeve 7 is pulled out from the corresponding rectangular tube 26, the motor 25, the screw rod 24, the slide seat 23 and other components can continue to drive the bottom plate 21 to drive the unprocessed shell on the rectangular tube 26 above it to move to the bottom of the punching head 3 to repeat the above steps, and then perform punching and opening work on multiple groups of shells on the fixture 2 in turn. When the bottom plate 21 drives the punched shell to move to the corresponding demolding mechanism 13, at this time, since the top plate 131 is located at the bottom of the shell, the electric push rod II132 drives the top plate 131 to move upward to lift the bottom of the shell, and then slowly pushes the shell out from the rectangular tube 26 to realize the demolding work, so that it is convenient for people to remove it, and then Then, buckle the shell to be processed on the rectangular tube 26, and repeat the above steps in sequence. When the bottom plate 21 drives the shells on the left side of the frame 4 to slide under the punch head 3 through the top rectangular tube 26, the shells are demoulded by the right demoulding mechanism 13 after punching holes in the shells. During the demoulding process, the shell to be processed is buckled on the rectangular tube 26 again. Then, the bottom plate 21 can be driven to drive the above-mentioned components to move to the left and slide under the punch head 3. The punch head 3 is used to punch holes in the shell on the top rectangular tube 26 of the bottom plate 21, and the demoulding mechanism 13 on the left side of the frame 4 is used to demould it, so as to realize assembly line processing.

[0037] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
