Description

Technical Field

[0001] The present invention relates to the field of dies, and in particular to a stamping die. Background Art

[0002] Stamping occupies a very important position in the existing process production. The process is to use the power of conventional or special stamping equipment to make the sheet metal directly subjected to deformation force in the die and deformed to obtain a certain shape. Compared with stamping parts, castings and forgings, they are thin, uniform, light and strong. In the stamping process, sometimes only the middle part of the sheet metal needs to be stamped to form the cavity.

[0003] During the use of traditional stamping dies, especially metal stamping, a loud noise will be generated at the moment the punch head contacts the metal plate, causing a loud noise in the entire workshop. In addition, the surface temperature of the punch head will be high during the continuous stamping process, affecting the actual service life. Therefore, how to solve this problem is what we need to consider. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a stamping die. The die is safer during actual use. In addition, the setting of the shell and the sound insulation board can reduce the noise generated during the use of the die. Combined with the use of alcohol, the punching head part can be quickly cooled to ensure its continuous service life.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The stamped workpiece on the left side is taken out, and then the metal plate to be stamped is placed. Compared with the existing technology, the entire taking out and placing operation is not located directly under the punching head. Using this method, the safety of actual use can be guaranteed.

[0029] As an embodiment of the present invention, a rotary stamping mechanism is provided above the base 1, and the rotary stamping mechanism includes a rotating plate 7 provided at the upper end of the base 1, and the upper end of the rotating plate 7 is symmetrically fixedly connected to two mounting seats 17, and the upper end of each mounting seat 17 is provided with a stamping groove 18. A rotating shaft 10 is rotatably connected between the upper and lower inner walls of the mounting cavity 8, and the upper end of the rotating shaft 10 passes through the inner top of the mounting cavity 8 and is fixedly connected to the lower end of the rotating plate 7. A motor 9 is installed at the inner bottom of the mounting cavity 8. The motor 9 is a servo motor that can change the rotation direction and speed. The servo motor refers to a motor that controls the mechanical element in the servo system. The servo motor is an engine operated by a component, which is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly.

The output shaft of the motor 9 is fixedly connected to the second gear 29, and the upper end of the rotating shaft 10 is fixedly connected to the first gear 28 meshing with the second gear 29;

[0030] As an embodiment of the present invention, rectangular boxes 19 are fixedly connected to the left and right sides of the housing 12, and piston plates 20 are slidably connected to the two rectangular boxes 19. A sound insulation board 27 is further connected to the inner side of the housing 12. The sound insulation board 27 is annular. During stamping, the contact between the punch head 15 and the metal plate is located in the closed space formed by the housing 12 and the mounting seat 17, which has a certain sound insulation effect. In addition, the provision of the sound insulation board 27 further improves the sound insulation effect.

[0031] A hollow ring 16 is provided on the inner side of the sound insulation board 27, and a plurality of connecting holes 30 are provided on the inner side of the hollow ring 16. The left and right sides of the shell 12 are fixedly connected with rectangular boxes 19, and the piston plates 20 are slidably connected in the two rectangular boxes 19. The inner side of the shell 12 is more connected with the sound insulation board 27. The sound insulation board 27 is annular, and a hollow ring 16 is provided on the inner side of the sound insulation board 27. A plurality of connecting holes 30 are provided on the inner side of the hollow ring 16. The upper end of the piston plate 20 on the left is fixedly connected to the lower end of the lifting plate 4 through the connecting rod 23. The bottom space of the rectangular box 19 on the left is connected to the outside through the air inlet pipe 22, and the bottom space of the rectangular box 19 on the left is connected to the hollow box 19 through the air outlet pipe 21. The ring 16 is connected, and one-way valves are installed in the air inlet pipe 22, the air outlet pipe 21, the liquid inlet pipe 24 and the liquid outlet pipe 25. The setting of the air inlet pipe 22 and the air outlet pipe 21 can generate a one-way gas flow from the outside → the left rectangular box 19 → the hollow ring 16 during the up and down movement of the piston plate 20 on the left. The setting of the liquid inlet pipe 24 and the liquid outlet pipe 25 can generate a one-way liquid flow from the liquid storage tank 11 → the right rectangular box 19 → the hollow ring 16 during the up and down movement of the piston plate 20 on the right. The one-way valve is also called a check valve or a non-return valve, which is used to prevent the reverse flow of oil in a hydraulic system, or to prevent the reverse flow of compressed air in a pneumatic system. Generally, there are two types of one-way valves: straight-through type and right-angle type.

[0032] In the present invention, during normal use, the metal plates to be punched are first placed in both punching slots 18, and then the hydraulic telescopic rod 3 is activated, which causes the lifting plate 4 to move downward, and finally drives the punching head 15 to move downward to achieve the punching work;

[0033] During stamping, the housing 12 will first contact the mounting seat 17. At this time, the housing 12 will move upward relative to the lifting plate 4 and compress the spring 26. During the overall stamping, the contact between the punch head 15 and the metal plate is located in the closed space formed by the housing 12 and the mounting seat 17, which has a certain sound insulation effect. In addition, the provision of the sound insulation board 27 further improves the sound insulation effect.

[0034] After the stamping is completed, the shell 12 moves down relative to the lifting plate 4. At this time, the right piston plate 20 in the corresponding rectangular box 19 will move upward, and the alcohol therein will be ejected through the liquid outlet pipe 25, and finally ejected from the multiple communicating holes 30 on the hollow ring 16. After the alcohol contacts the high-temperature punching head 15, it will quickly evaporate and absorb heat, thereby reducing the temperature of the punching head 15 and avoiding the high temperature during continuous stamping. In addition, during stamping, the shell 12 will first contact the mounting seat 17. At this time, the shell 12 will move up relative to the lifting plate 4, allowing the left piston plate 20 to move downward in the corresponding rectangular box 19, and eject gas through the multiple communicating holes 30 on the hollow ring 16, so that the residual alcohol on the punching head 15 will evaporate quickly, avoiding the occurrence of residual alcohol.

[0035] It should be noted that after the stamping is completed, the starting motor 9 is rotated, and then the mounting seats 17 on the left and right sides are exchanged, the stamped workpiece on the left side is taken out, and then the metal plate to be stamped is placed in. Compared with the existing technology, the entire taking out and placing operation is not located directly below the punching head 15. Using this method, the safety of actual use can be guaranteed.
