The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a stamping die with a noise reduction function comprises a base and is characterized in that supporting plates are arranged on two sides of the upper end of the base, a horizontal mounting plate is arranged at the upper ends of the two supporting plates, a hydraulic cylinder is arranged in the middle of the upper end of the mounting plate, a piston rod of the hydraulic cylinder penetrates through the mounting plate and is connected with a lifting plate, a male die is arranged in the middle of the lower end of the lifting plate, guide rods are arranged on two sides of a male die at the lower end of the lifting plate, guide cylinders matched with the guide rods are arranged on two sides of the upper end of the base, a porous sound absorption material layer is arranged in the cylinder walls of the guide cylinders, a plurality of through holes communicated with the interior of the guide cylinders and the porous sound absorption material layer are arranged on the inner walls of the guide cylinders, a female die is arranged below the male die, supporting columns are, the lower extreme of piston is equipped with a plurality of springs, the lower extreme and the base fixed connection of spring, and one side that the backup pad was kept away from to the bottom of barrel is equipped with the outlet duct, and the other end of outlet duct even has the hose, and the other end of hose runs through the die and communicates with the depressed part of die.

The distance between the through holes is gradually increased along the direction from bottom to top of the guide cylinder.

And a plurality of telescopic rods are arranged between the bottom of the female die and the base.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses utilized the principle that the air is compressed in the guide cylinder, make the terrace die have certain buffering when pushing down, and make the sound that produces in the guide cylinder minimize, the porous sound absorbing material layer that sets up in the section of thick bamboo wall of guide cylinder simultaneously and the through-hole that communicates the guide cylinder inside with porous sound absorbing material layer can both effectively reduce the speed of the air that the guide cylinder inner wall surface flows through, thereby can effectual noise reduction, avoided the too big health that harms the staff of noise; and the inside air of barrel can enter into the inside of hose through the outlet duct during the punching press, and in the twinkling of an eye that the terrace die left from the die, the inside air of hose entered into the depressed part of die and ejected the work piece, very convenient and fast.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: 1. a base; 2. a support plate; 3. mounting a plate; 4. a hydraulic cylinder; 5. a male die; 6. a female die; 7. a support pillar; 8. a barrel; 9. a piston; 10. a spring; 11. an air outlet pipe; 12. a hose; 13. a lifting plate; 14. a guide bar; 15. a guide cylinder; 16. a layer of porous sound absorbing material; 17. a telescopic rod.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

as shown in figure 1, the stamping die with the noise reduction function comprises a base 1, wherein supporting plates 2 are respectively arranged on two sides of the upper end of the base 1, a horizontal mounting plate 3 is arranged on the upper ends of the two supporting plates 2, a hydraulic cylinder 4 is arranged in the middle of the upper end of the mounting plate 3, a piston rod of the hydraulic cylinder 4 penetrates through the mounting plate 3 and is connected with a lifting plate 13, a male die 5 is arranged in the middle of the lower end of the lifting plate 13, guide rods 14 are respectively arranged on two sides of the male die 5 at the lower end of the lifting plate 13, guide cylinders 15 matched with the guide rods 14 are respectively arranged on two sides of the upper end of the base 1, a porous sound-absorbing material layer 16 is arranged in the cylinder walls of the guide cylinders 15, a plurality of through holes communicated with the interior of the guide cylinders 15 and the porous sound-absorbing material layer 16 are arranged on the inner walls of the guide, the inside slip of barrel 8 is equipped with horizontally piston 9, and the lower extreme and the piston 9 fixed connection of support column 7, the lower extreme of piston 9 are equipped with a plurality of springs 10, the lower extreme and the base 1 fixed connection of spring 10, and one side that backup pad 2 was kept away from to the bottom of barrel 8 is equipped with outlet duct 11, and the other end of outlet duct 11 even has hose 12, and the other end of hose 12 runs through die 6 and communicates with the depressed part of die 6.
