[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1 A low alloy high strength steel stamping die comprises a lower die base 1, a lower die block 2 connected to the upper surface of the lower die base 1, a guide column 11 arranged on the upper surface of the lower die base 1, a guide sleeve 12 sleeved on the upper surface of the guide column 11, and an upper die base 3 arranged on the outer surface of the guide sleeve 12, a stamping assembly 4 is arranged at the bottom of the upper die base 3, and a cleaning assembly 5 for cooling and chip cleaning is arranged inside the lower die base 1.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4The cleaning component 5 includes a cavity 51 arranged inside the lower module 2, and a fan 52 arranged inside the cavity 51. A mold groove 53 is opened on the upper surface of the lower module 2, and a through hole 54 is opened on the inner wall of the mold groove 53. The through hole 54 is connected with the cavity 51. A bracket 55 is arranged on one side of the lower module 2, and an electric push rod 56 is arranged on one side of the bracket 55. A brush plate 57 is arranged on the telescopic end of the electric push rod 56. The bottom of the brush plate 57 contacts the upper surface of the lower module 2. A connecting pipe 58 is passed through the center of the brush plate 57. One end of the connecting pipe 58 is connected with the inside of the cavity 51. An infrared sensor 59 is arranged on one side of the bracket 55. The infrared sensor 59 is connected with the electric push rod 56 by signal. When the workpiece is stamped, cooling air is introduced into the mold groove 53 through the fan 52 in the cavity 51, so that the temperature inside the mold groove 53 can be reduced when the mold is connected and stamped, thereby avoiding the damage caused by Overheating caused by friction, and during the stamping process, chips or residues will be generated on the upper surface of the lower module 2. When the workpiece is fed and moved, these chips will be guided into the die groove 53, thereby affecting the smoothness of the part surface. Therefore, the chips are cleaned from the upper surface of the lower module 2 through the action of the electric push rod 56 and the brush plate 57 to keep it tidy. In addition, since a connecting pipe 58 is passed through the center of the brush plate 57, one end of the connecting pipe 58 is connected to the interior of the cavity 51, so the debris on the upper surface of the lower module 2 can also be blown away, further improving the cleaning effect. In addition, because an infrared sensor 59 is provided on one side of the bracket 55, the infrared sensor 59 can sense the departure of the upper die seat 3 and transmit the signal to the electric push rod 56. Therefore, it can not only prevent the electric push rod 56 from being pressed, but also more conveniently control the cleaning frequency, thereby improving the stamping efficiency and extending the life of the mold.

[0025] The bottom of the upper die seat 3 is connected with a pad 6, and the bottom of the pad 6 is connected with a fixing plate 7. The pad 6 plays a buffering role to reduce the vibration and impact of the die during operation, thereby extending the service life of the die.

[0026] The stamping assembly 4 includes a spring column 41 arranged at the bottom of the fixed plate 7, a pressure plate 42 arranged at one end of the spring column 41, and a stamping block 43 arranged at the bottom of the fixed plate 7. The lower end of the stamping block 43 passes through the pressure plate 42, and the outer surface of the stamping block 43 is adapted to the interior of the die groove 53.

[0027] A cutting knife 8 is provided at the bottom of the fixed plate 7, and the lower end of the cutting knife 8 passes through the pressing plate 42. The bottom of the cutting knife 8 passes through the pressing plate 42 and contacts the upper surface of the lower module 2, so that during stamping, the cutting knife 8 cuts it according to the designed size to achieve continuous stamping.

[0028] A spring 9 is provided on the upper surface of the lower die base 1, and a top block 91 is provided on the upper surface of the spring 9. A connecting groove 531 is provided on the inner wall of the die groove 53. The top block 91 and the spring 9 are both movably connected to the inside of the connecting groove 531. When the stamping is completed, the reset of the spring 9 will drive the top block 91 upward, thereby ejecting the stamped part out of the die groove 53.

[0029] The upper surface of the lower module 2 and the outer surface of the punching block 43 are both provided with a protective layer, which is a component made of metal, and can be steel or aluminum alloy, so as to improve their wear resistance, corrosion resistance and surface finish.

[0030] Specifically, when the workpiece is punched, the workpiece is placed between the fixed plate 7 and the lower module 2, and the pressure is transmitted to the punching block 43 by the punching equipment. The outer surface of the punching block 43 contacts the workpiece, and the workpiece is processed according to the shape of the die groove 53. Since the bottom of the upper die seat 3 is connected with the pad 6, and the bottom of the pad 6 is connected with the fixed plate 7, the pad 6 plays a buffering role, reducing the vibration and impact of the mold during operation, thereby extending the service life of the mold. In addition, because the bottom of the fixed plate 7 is provided with a cutting knife 8, the lower end of the cutting knife 8 passes through the pressing plate 42, and the bottom of the cutting knife 8 passes through the pressing plate 42 and contacts the upper surface of the lower module 2, so that when punching, the cutting knife 8 Cut it according to the designed size to achieve continuous stamping and ensure the stability and accuracy of the stamping block 43 during the stamping process. After the stamping is completed, the pressure is released. Because the upper surface of the lower die base 1 is provided with a spring 9, and the upper surface of the spring 9 is provided with a top block 91, the outer surface of the top block 91 is movably connected with the inside of the die groove 53. When the stamping is completed, the reset of the spring 9 will drive the top block 91 upward, thereby ejecting the stamped parts out of the die groove 53, so that the entire stamping process is completed. Because the upper surface of the lower module 2 and the outer surface of the stamping block 43 are provided with a protective layer, their wear resistance, corrosion resistance and surface finish are improved. Since the mold will overheat after continuous stamping. Reaction, therefore, cooling air is introduced into the interior of the die groove 53 through the fan 52 in the cavity 51, so that the mold can reduce the temperature inside the die groove 53 when the mold is connected for stamping, avoiding overheating caused by friction. At the same time, during the stamping process, chips or residues will be generated on the upper surface of the lower module 2. In order to prevent these chips from being guided into the interior of the die groove 53 when the workpiece is fed and moved, thereby affecting the smoothness of the part surface, it is necessary to use the electric push rod 56 and the brush plate 57 to clean the chips from the upper surface of the lower module 2 to keep it tidy. Since the position of the brush plate 57 corresponds to the position of the cutting knife 8, it is only necessary to clean the chips in the cutting area in advance. It will not be guided into the inside of the die groove 53, and the electric push rod 56 will shrink when pressing down so that the brush plate is located inside the bracket 55, which will not affect the pressing down of the stamping assembly 4, and because a connecting tube 58 is passed through the center of the brush plate 57, one end of the connecting tube 58 is connected to the inside of the cavity 51, so the debris on the upper surface of the lower module 2 can also be blown away, further improving the cleaning effect, and because an infrared sensor 59 is provided on one side of the bracket 55, the infrared sensor 59 can sense the departure of the upper die seat 3 and transmit the signal to the electric push rod 56 at the same time, so it can not only prevent the electric push rod 56 from being pressed, but also can more conveniently control the cleaning frequency, thereby improving the stamping efficiency and extending the life of the mold.
