Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of new energy battery shell production equipment, and in particular relates to a new energy battery shell stamping die. Background Art
[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping, and is called a cold stamping die.
[0003] Since the force of the hydraulic press is very large, in order to ensure the hardness of the mold, the carbon content of the mold itself is relatively high. Therefore, the mold itself is hard and brittle, and lacks an effective buffer mechanism. There is a certain crushing rate during the stamping process, which causes the problem of easy damage to the conventional new energy battery shell stamping mold.
[0004] To this end, we proposed a new energy battery shell stamping die to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the problem that conventional new energy battery shell stamping dies are easily damaged, and proposes a new energy battery shell stamping die.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A new energy battery housing stamping die comprises a die body, an oil groove is provided inside the die body, a buffer piston is slidably and sealably installed inside the oil groove, a first oil pipe is fixedly connected to the side of the die body, a piston is slidably and sealably installed inside the first oil pipe, and a tension spring is fixedly connected between the first oil pipe and the piston. When the die body is pressed, the buffer piston is preferentially pressed, and the buffer piston acts on the oil, and the oil reduces the pressure and then acts on the piston, and the piston acts on the tension spring, and the tension spring is used to buffer the force, thereby reducing the damage to the die body caused by the stamping and improving the practicality.
[0008] Preferably, a sealing cover is threadedly sealed on the piston, and the sealing cover is opened to facilitate the injection of oil into the first oil pipe.
[0009] Preferably, the sealing cover comprises a cover body, and a hexagonal groove is formed on the upper end of the cover body to facilitate docking with a hexagonal wrench.
[0010] Preferably, the buffer piston includes a squeeze plate and a plug body, and the squeeze plate is fixedly connected to the upper end of the plug body. When the squeeze plate is subjected to pressure, the oil in the oil tank is acted on through the plug body; when the squeeze plate loses pressure, the tension spring acts on the piston, and the piston acts on the oil, and the plug body is driven to reset upwards through the oil, so as to facilitate the reset of the buffer piston.
[0011] Preferably, the buffer piston further comprises a return spring, the upper end of which is fixedly connected to the plug body. When filling oil, the return spring is used to maintain the height of the buffer piston, so as to facilitate the filling of oil into the oil tank.
[0012] Preferably, the first oil pipe includes a pipe body and a connecting ring, and the connecting ring is fixedly connected to the lower part of the pipe body. When the buffer piston sinks, the oil is squeezed into the pipe body, and the oil pressure acts on the piston through the pipe body, which facilitates the piston to guide the oil pressure to the tension spring.
[0013] Preferably, the piston comprises a threaded ring, a second oil pipe and an annular plug, wherein the second oil pipe is fixedly connected between the threaded ring and the annular plug. When the bottom of the annular plug is subjected to oil pressure, the annular plug acts on the tension spring through the second oil pipe and the threaded ring, so that the piston overcomes the elastic force of the tension spring and rises upward, which is convenient for reducing the force and then performing buffering.
[0014] In summary, the technical effects and advantages of the utility model are as follows:
[0015] 1. When the mold body is pressed, the buffer piston is pressed first, and the buffer piston acts on the oil. The oil reduces the pressure and then acts on the piston. The piston acts on the tension spring, and the tension spring is used to buffer the force, which reduces the damage to the mold body caused by stamping and improves practicality.
[0016] 2. When the extrusion plate is subjected to pressure, it acts on the oil in the oil tank through the plug body; when the extrusion plate loses pressure, the tension spring acts on the piston, which acts on the oil through the piston, and the plug body is driven upward to reset through the oil, which facilitates the reset of the buffer piston.
[0017] 3. When the buffer piston sinks, the oil is squeezed into the tube body, and the oil pressure is applied to the piston through the tube body, making it convenient for the piston to guide the oil pressure to the tension spring.
[0018] 4. When the bottom of the annular plug is subjected to oil pressure, the annular plug acts on the tension spring through the second oil pipe and the threaded ring, so that the piston overcomes the elastic force of the tension spring and rises upward, which is convenient for reducing the force and then buffering.
