DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 3 A stamping forming device for processing sheet metal parts of machine tools, comprising a hydraulic cylinder 1 and a punch head 2, a mounting rod 3 is fixedly installed at the bottom end of the driving shaft of the hydraulic cylinder 1, a slot is vertically opened at the bottom end of the mounting rod 3, a hollow tube 4 with one end designed to be closed is fixedly installed in the slot through a mounting component, the mounting component comprises a mounting ring 12 fixedly sleeved on the hollow tube 4 and a plurality of connecting rods 13 fixedly installed on the surface of the mounting ring 12, one end of the plurality of connecting rods 13 are fixedly connected to the slot wall, a suction cup 5 is fixedly installed at the open end of the hollow tube 4, an insert block 6 for inserting into the slot is fixedly installed at the top end of the punch head 2, the insert block 6 is attracted to the suction cup 5, and a through opening 11 is opened on the surface of the mounting rod 3;

[0023] A vent 7 is provided on the surface of the hollow tube 4. A rotating port is provided at one end of the hollow tube 4 which is closed. A rotating shaft 8 is installed in the rotating port for sealing and rotating. An arc plate 9 for covering and blocking the vent 7 is fixedly installed at one end of the rotating shaft 8 located in the hollow tube 4 through a connecting rod. The rotating shaft 8 is connected to the hollow tube 4 through an elastic component. An adjusting wheel is fixedly installed at one end of the rotating shaft 8 located outside. The elastic component includes a torsion spring 10 sleeved on the rotating shaft 8. Both ends of the torsion spring 10 are fixedly connected to the hollow tube 4 and the adjusting wheel respectively.

[0024] When the punch head 2 needs to be installed, first align the plug block 6 at the top of the punch head 2 with the slot and insert it so that the plug block 6 and the suction cup 5 are tightly pressed against each other. At this time, since the vent 7 is covered and sealed by the arc plate 9, when the suction cup 5 is deformed by the pressure, the gas in the suction cup 5 will slip out from the gap between the contact surface of the suction cup 5 and the plug block 6, thereby completing the adsorption of the plug block 6 and completing the fixation of the punch head 2.

[0025] When the punch head 2 needs to be disassembled, it is only necessary to control the rotation of the rotating shaft 8 so that the arc plate 9 no longer covers the vent 7. At this time, the gas in the outside will enter the hollow tube 4 from the vent 7, thereby releasing the adsorption of the suction cup 5 on the plug 6, and then the punch head 2 can be removed. When the rotating shaft 8 is released, the rotating shaft 8 will quickly rotate and reset with the arc plate 9 under the elastic potential energy of the torsion spring 10, and the arc plate 9 will cover and block the vent 7 again.

[0026] The surface of the mounting rod 3 is symmetrically provided with a limiting assembly, which is used to limit the separation of the punch head 2 from the mounting rod 3. The limiting assembly includes a straight rod 14, a threaded rod 15 and a limiting block 16 fixedly installed at the bottom end of the straight rod 14. The surface of the mounting rod 3 is symmetrically fixed with a connecting rod, and a fixing ring is fixedly installed at one end of the connecting rod. The two straight rods 14 are rotatably installed in the two fixing rings respectively, and the top ends are vertically provided with thread grooves. The two threaded rods 15 are vertically threadedly installed in the two thread grooves respectively. The surface of the punch head 2 is symmetrically provided with a limiting opening 17 for the end of the limiting block 16 to enter;

[0027] The two threaded rods 15 are controlled to rotate together by a pressing assembly, which includes a pressing ring 18 sleeved on the mounting rod 3, the lower surface of the pressing ring 18 is fixedly connected to the top ends of the two threaded rods 15, and the surface of the mounting rod 3 is symmetrically vertically provided with a slide groove, in which a spring rod 19 is vertically fixedly installed, and a rectangular rod 20 is fixedly installed on the top end of the spring rod 19, and one end of the two rectangular rods 20 is fixedly connected to the inner ring wall of the pressing ring 18;

[0028] When the punch head 2 needs to be installed, first control the pressing ring 18 to move downward so that the two threaded rods 15 move downward together. At this time, the two spring rods 19 will shrink together. Under the cooperation of the threads, since the two threaded rods 15 cannot rotate, the two straight rods 14 will respectively rotate with the two limiting blocks 16. Then, after the insert block 6 is inserted into the slot, the punch head 2 is rotated so that the two limiting openings 17 on the side wall of the punch head 2 correspond to the positions of the two limiting blocks 16 respectively. Then, the pressing ring 18 is released, and the pressing ring 18 will be on the two straight rods 14. The spring rod 19 quickly moves up and resets under the elastic potential energy, and the two straight rods 14 also quickly rotate and reset. One end of the two limiting blocks 16 will be respectively turned into the two limiting openings 17, thereby having a certain fixing effect on the punch head 2, preventing the punch head 2 from falling directly when the suction cup 5 loosens the adsorption of the punch head 2, thereby improving the stability of the fixed punch head 2, and also preventing the punch head 2 from falling directly after disassembling the punch head 2 and releasing the adsorption of the suction cup 5 and the plug block 6, thereby colliding with other objects and causing damage.

[0029] When the punch head 2 needs to be installed, the plug block 6 at the top of the punch head 2 is first aligned with the slot and inserted so that the plug block 6 and the suction cup 5 are tightly pressed against each other. At this time, the vent 7 is covered and sealed by the arc plate 9. When the suction cup 5 is deformed by the pressure, the gas in the suction cup 5 will slip out from the gap between the contact surface of the suction cup 5 and the plug block 6, thereby completing the adsorption of the plug block 6 and the fixation of the punch head 2. When the punch head 2 needs to be disassembled, it is only necessary to control the rotation of the rotating shaft 8 so that the arc plate 9 no longer covers the vent 7. At this time, the gas in the outside will enter the hollow tube 4 from the vent 7, thereby releasing the adsorption of the suction cup 5 on the plug block 6, and then the punch head 2 can be removed. The installation and disassembly of the punch head 2 can be completed quickly, avoiding the cumbersome steps of using screw and nut fixings, and improving the work efficiency of replacing the punch head 2.

[0030] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
