[0035] In the embodiment, when the stamping die 3 is air-cooled, the fan 604 is clamped in the fixed groove 10, then the fan 604 is fixed with the limiting plate 603 through the fixing piece 12 to prevent the fan 604 from shaking, then the first rotating block 606 is driven to move downward while the output end of the electric telescopic rod 605 is telescoped, then the second rotating block 607 is driven to move while the first rotating block 606 moves downward, the second rotating block 607 drives the limiting plate 603 to rotate inside the limiting block 602, and the movement angle of the limiting plate 603 is limited by the first rotating block 606 and the second rotating block 607, so that the angle of the fan 604 is adjusted, and then the output angle of the fan 604 is adjusted according to the stamping operation of the stamping die 3 through repeated telescoping of the electric telescopic rod 605.

[0036] Specifically, as shown in Figure 5 , the stamping die 3 is fixedly connected with the bottom plate 4 on both sides, the top of the bottom plate 4 is fixedly connected with the limiting spring 7, the top of the limiting spring 7 is fixedly connected with the top plate 8, the top plate 8 is made of rubber, the top plate 8 is clamped with the cooling pipe 504, and the top of the bottom plate 4 is fixedly connected with the supporting rod 9 on both sides, and the supporting rod 9 is slidingly connected with the bottom of the top plate 8.

[0037] Specifically, as shown in Figure 4 , the right side of the limiting plate 603 is provided with the fixed groove 10, the fixed groove 10 is clamped with the left side of the fan 604, the two sides of the fan 604 are fixedly connected with the fixed plate 11, the outer side of the fixed plate 11 is inserted with the fixing piece 12, and the fixing piece 12 is screw-connected with the limiting plate 603.

[0038] In the embodiment, by arranging the bottom plate 4, the limiting spring 7, the top plate 8 and the supporting rod 9, when the cooling pipe 504 moves downward, the top plate 8 at the bottom moves in the moving direction of the cooling pipe 504, then the top plate 8 generates downward pressure on the limiting spring 7 at the bottom to make the limiting spring 7 contract, and the supporting rod 9 limits the moving direction of the top plate 8 to prevent the top plate 8 from deviating from the movement track, then when the cooling pipe 504 moves upward, the limiting spring 7 drives the top plate 8 to move upward to assist in resetting the cooling pipe 504, so as to ensure the cooling effect of the cooling pipe 504, and by arranging the fixed groove 10, the fixed plate 11 and the fixing piece 12, the fan 604 is clamped in the fixed groove 10, then the fan 604 is fixed with the limiting plate 603 through the fixing piece 12 to prevent the fan 604 from shaking and affecting the cooling effect.

[0041] In this embodiment: By setting the mounting plate 13 and the shock-absorbing pad 14, the mounting plate 13 provides a mounting base for the shock-absorbing pad 14, and the shock-absorbing pad 14 is interposed between the circulating pump 502 and the stamping device body 2. When the circulating pump 502 operates and generates vibration, the shock-absorbing pad 14 can effectively block the direct transmission of vibration between the two by virtue of its elastic material properties. The vibration energy of the circulating pump 502 is mostly absorbed and dissipated by the shock-absorbing pad 14 when passing through it, thereby avoiding direct conduction of vibration to the stamping device body 2 and reducing the impact of vibration on the overall structural stability of the stamping device. By setting the shock-absorbing cushion 15, the stamping device will generate a huge impact force during the working process, especially in the moment when the stamping die 3 contacts the workpiece. This impact force will be transmitted to the ground through the base 1 of the device. The shock-absorbing cushion 15 is made of materials such as rubber that have good elastic and damping properties, and can undergo elastic deformation under the action of impact force, converting most of the impact energy into elastic potential energy and storing it up, and converting part of the energy into heat energy through the internal friction of its own material, thereby effectively reducing the vibration energy transmitted to the ground.

[0042] Working principle: in the process of using the stamping device with cooling structure of machine tool shell, first, the machine tool shell to be processed is placed on the processing end of the stamping device body 2, preparing for the subsequent stamping operation, when the stamping die 3 is continuously working and the temperature rises, the circulating pump 502 is started quickly, the circulating pump 502 draws cooling water from the water tank 501, the corrugated pipe 503 at the output end of the circulating pump 502 effectively adapts to the slight vibration and displacement generated during the operation of the stamping device due to its excellent flexibility, which eliminates the hidden troubles such as pipe rupture or loose connection caused by rigid connection, and successfully delivers the cooling water to the inside of the cooling pipe 504, which tightly surrounds the outside of the stamping die 3, and by means of heat conduction principle, the cooling water efficiently absorbs the heat emitted by the stamping die 3, so as to realize the effective reduction of the temperature of the die, and the cooling water after absorbing heat flows back to the water tank 501 under the continuous driving of the circulating pump 502, completing a complete cooling cycle, when the cooling pipe 504 vibrates and displaces due to the impact energy generated during the working of the stamping die 3, the clamping block 508 quickly transmits the vibration energy to the connecting block 507, the connecting block 507 moves downward under the force and transmits the energy to the auxiliary spring 506 inside the shock absorbing frame 505, the auxiliary spring 506 shrinks under the pressure and successfully absorbs the vibration energy, at the same time, the reset spring 509 at the top is stretched due to the downward movement of the connecting block 507, after the auxiliary spring 506 completes energy absorption, the reset spring 509 drives the connecting block 507 to move upward with its elasticity, accurately resets the cooling pipe 504, and effectively ensures the stability and reliability of the cooling effect of the cooling pipe 504, in the air cooling link, first, the fan 604 is stably clamped in the fixed groove 10, then the fan 604 and the limiting plate 603 are tightly fixed with the fixing piece 12, which effectively prevents the fan 604 from shaking, then the output end of the electric telescopic rod 605 telescopes, driving the first rotating block 606 to move downward, the downward movement of the first rotating block 606 links the movement of the second rotating block 607, and then drives the limiting plate 603 to rotate inside the limiting block 602, while the first rotating block 606 and the second rotating block 607 accurately limit the movement angle of the limiting plate 603, realizing flexible adjustment of the angle of the fan 604, through repeated telescoping operation of the electric telescopic rod 605, the fan 604 can perfectly realize dynamic adjustment of the output angle with the stamping operation of the stamping die 3, ensuring that the air cooling effect is always in the best state, so as to solve the problem that the existing stamping device with cooling structure of machine tool shell has the important function of cooling, but the cooling structure in the water cooling system is easy to move due to the vibration of the stamping die 3, which affects the cooling effect of the stamping die 3, and the output angle of the air cooling system of the device is not convenient to adjust quickly, and it is not convenient to adjust with the stamping operation of the stamping die 3, which is easy to make the temperature of the die and equipment too high, and then affects the processing precision and service life.

[0043] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
