[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. It is usually called a cold stamping die. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation, thereby obtaining the desired parts.

[0003] When the precision stamping die in the prior art is stamping a workpiece, the waste generated by the stamping will be discharged from the stamping die through the waste channel under the action of its own gravity. However, since the waste will be deformed during the stamping process, it will be blocked between the waste channels, causing the waste to not be discharged from the waste channel in a timely and smooth manner, thereby affecting the normal progress of the stamping and causing serious damage to the die itself.

[0015] A stamping method of a precision stamping device comprises the following steps: S1: Before stamping the precision parts, the power provided by the hydraulic rod is used to drive the moving frame to move to the side close to the lower mold body, so that the oil storage pipe is located directly above the discharge pipeline of the lower mold body. Then, the power provided by the electric push rod is used to drive the two moving blocks to move, so that the distance between the two nozzles corresponds to the inner diameter of the discharge pipeline. Then, the power provided by the automatic telescopic rod is used to drive the rectangular plate to move downward. During the downward movement of the rectangular plate, the rack plate is used to drive the connecting gear to rotate, so that the connecting gear drives the rotating column and the third conical wheel The gear wheel is rotated, so that the third conical wheel drives the fourth conical wheel to rotate, so that the fourth conical wheel drives the rotating column and the rotating gear to rotate. When the rotating gear rotates, the rack ring is driven to rotate, so that the rack ring drives the oil storage pipe to rotate, and then the nozzle rotates in the process of moving downward. At the same time, when the oil storage pipe rotates, the nozzle is opened, so that the lubricating oil in the oil storage tank passes through the oil delivery pipe, the oil storage pipe, the telescopic pipe and the nozzle and is sprayed on the inside of the lower mold body. Similarly, the lubricating oil is sprayed on the other discharge pipeline, and then the moving frame returns to its original position; S2: In the process of stamping precision parts, the hydraulic mechanism is used to drive the upper mold body to move downward, so that the upper mold body cooperates with the lower mold body to stamp the precision parts, and then the upper mold body moves upward to complete the stamping process of the precision parts. When the upper mold body moves upward, the upper mold body drives the connecting plate to move upward. When the connecting plate triggers the first touch switch, the first touch switch starts the water pump to run, and the power provided by the water pump is used to extract the coolant inside the water tank into the inside of the connecting pipe, thereby replacing the coolant inside the connecting pipe. The replaced coolant enters the inside of the water tank after passing through the connecting box and the delivery pipe, and then the coolant is cooled by the semiconductor refrigeration sheet. When the coolant passes through the inside of the connecting box, When the gear wheel is turned, the spiral blade rotates under the impact of the coolant, so that the spiral blade drives the rotating shaft to rotate, and then the rotating shaft drives the first conical wheel to rotate, so that the first conical wheel drives the second conical wheel meshing with it to rotate, so that the second conical wheel drives the rotating shaft and the turntable to rotate, and then the turntable drives the connecting column to rotate, and at the same time, the connecting column drives the toothed disc to swing periodically on the outer surface of the connecting box, and during the swinging of the toothed disc, the toothed disc drives the toothed rod to move back and forth periodically, so that the toothed rod drives the rubber hammer to move back and forth periodically, and then the rubber hammer knocks the placement rack, so that the placement rack vibrates, so that the waste stuck in the discharge pipeline is discharged from the discharge pipeline under the action of vibration; S3: When the first touch switch is triggered, the rotating motor starts, and the power provided by the rotating motor drives the adjusting plate to rotate, so that when the pressing plate triggers the second touch switch, the rotating motor is turned off. At this time, the first sealing tube and the second sealing tube are respectively connected to the two discharge pipes on the placement rack, and then the power provided by the cylinder is used to drive the electromagnet to move upward, so that the electromagnet extends into the discharge pipe of the placement rack, and the electromagnet is used to absorb the waste, so that the waste is absorbed on the electromagnet, and then the power provided by the cylinder is used to drive the electromagnet to move downward, so that the waste is removed from the placement rack. The waste is pulled out from the inside, and the power provided by the air pump is used to discharge the air inside the first sealed tube and the second sealed tube to the outside after passing through the suction pipe. Therefore, the waste is discharged from the placement rack under the action of the suction force of the air flow and the suction force of the electromagnet, thereby further preventing the waste from being stuck inside the placement rack. After the waste is sucked out, the power provided by the rotating motor is used again to drive the adjustment plate back to its original position. At this time, the first sealed tube and the second sealed tube are not in contact with the bottom surface of the placement rack. Then the magnetism of the electromagnet is disconnected, and the air pump is used to convey airflow to the inside of the first sealed tube and the second sealed tube, thereby discharging the waste, which is convenient for the subsequent adsorption of the waste.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention is provided with a knocking unit. After the precision parts are stamped, the spiral blades are driven by water flow to rotate, so that the rubber hammer knocks the placement rack, which makes the placement rack vibrate, and the waste material blocked in the discharge pipeline is discharged under the action of vibration, thereby preventing the waste material from being stuck in the discharge pipeline and damaging the mold.

[0017] The present invention is provided with an adsorption unit, so that during the knocking process, the device utilizes the adsorption of the electromagnet and the adsorption of the airflow to assist the knocking unit in discharging the waste from the inside of the discharge pipeline, thereby further avoiding the waste from being stuck in the discharge pipeline, thereby ensuring the smoothness of the waste discharge.

[0018] The present invention is provided with a lubrication mechanism, so that the device can spray lubricating oil on the inside of the discharge pipeline before stamping precision parts, thereby reducing the friction between the waste material and the discharge pipeline, thereby avoiding the waste material from being stuck in the inside of the discharge pipeline, and further ensuring the smoothness of the waste discharge. Through the coordinated use of the processing mechanism and the lubrication mechanism, the phenomenon of damage to the mold caused by untimely waste discharge can be avoided, thereby ensuring the normal operation of the precision parts stamping work.

Therefore, under the action of the suction force of the air flow and the suction force of the electromagnet 2209, the waste is discharged from the placement rack 12, and the waste is further prevented from being stuck inside the placement rack 12. After the waste is sucked out, the power provided by the rotating motor 2201 is used again to drive the adjustment plate 2202 back to its original position. At this time, the first sealed tube 2206 and the second sealed tube 2207 are not in contact with the bottom surface of the placement rack 12.

When the cooling liquid passes through the interior of the connecting box (2108), the spiral blade (2112) The rotating shaft (2111) rotates under the impact of the coolant, so that the spiral blade (2112) drives the rotating shaft (2111) to rotate, and then the rotating shaft (2111) drives the first conical wheel (2113) to rotate, so that the first conical wheel (2113) drives the second conical wheel (2115) meshed with it to rotate, so that the second conical wheel (2115) drives the rotating shaft (2114) and the rotating disk (2116) to rotate, and then the rotating disk (2116) drives the connecting column (2117) to rotate, and at the same time the connecting column (21 17) driving the toothed disc (2118) to periodically swing on the outer surface of the connection box (2108), and during the swinging process of the toothed disc (2118), the toothed disc (2118) drives the toothed rod (2119) to periodically move back and forth, so that the toothed rod (2119) drives the rubber hammer (2120) to periodically move back and forth, and then the rubber hammer (2120) strikes the placement rack (12), thereby causing the placement rack (12) to vibrate, so that the waste stuck in the discharge pipeline is discharged from the discharge pipeline under the action of the vibration; S3: When the first touch switch (2104) is triggered, the rotating motor (2201) is started, and the power provided by the rotating motor (2201) is used to drive the adjustment plate (2202) to rotate, so that when the pressing plate (2205) triggers the second touch switch (2204), the rotating motor (2201) is turned off. At this time, the first sealing tube (2206) and the second sealing tube (2207) are respectively connected to the two discharge pipes on the placement rack (12), and then the power provided by the cylinder (2208) is used to drive the electromagnet (2209) to move upward, so that the electromagnet (2209) extends into the discharge pipe of the placement rack (12), and the electromagnet (2209) is used to absorb the waste, so that the waste is absorbed on the electromagnet (2209), and then the power provided by the cylinder (2208) is used to drive the electromagnet (2209) to move downward, so that the waste is discharged. The waste is pulled out from the inside of the placement rack (12), and the power provided by the air pump (2210) is used to discharge the air inside the first sealed tube (2206) and the second sealed tube (2207) to the outside through the suction pipe (2211), so that the waste is discharged from the placement rack (12) under the action of the air suction force and the suction force of the electromagnet (2209), thereby further preventing the waste from being stuck inside the placement rack (12). After the waste is sucked out, the power provided by the rotating motor (2201) is used again to drive the adjustment plate (2202) back to its original position. At this time, the first sealed tube (2206) and the second sealed tube (2207) are not in contact with the bottom surface of the placement rack (12), and then the magnetism of the electromagnet (2209) is disconnected, and the air pump (2210) is used to transport airflow to the inside of the first sealed tube (2206) and the second sealed tube (2207), thereby discharging the waste, thereby facilitating the subsequent adsorption of the waste.
