At present, the stamping die requires the staff to manually lubricate each guide mechanism with oil, which undoubtedly increases the complexity of the operation and the workload. This lubrication method is not only inefficient, but also easily leads to uneven lubrication, which in turn affects the service life of the die and the stamping quality. Therefore, we propose a stamping die for the inner plate of the top side beam of an automobile. Utility Model Content

The two screw rods 10 are threadedly connected to a moving block 11 on one side close to the dual-axis motor 9. The top and bottom of the two moving blocks 11 on the opposite side are fixedly connected to a push rod 12. A fixed mold 14 is fixedly installed at the center of the top of the base 1. Oil spray heads 18 are fixedly installed at the four corners of the top of the top plate 2. The centers of the opposite sides of the two oil storage chambers 6 are fixedly connected to oil outlet pipes 15. The upper ends of the two oil outlet pipes 15 are fixedly connected to a telescopic pipe 16. The upper ends of the two telescopic pipes 16 are fixedly connected to a shunt pipe 17. The two ends of the two shunt pipes 17 are respectively fixedly connected to the tops of the four oil spray heads 18. A movable mold 19 is fixedly installed at the center of the bottom of the top plate 2.

[0015] A spring 5 is sleeved on the surface of the guide column 4, the lower end of the spring 5 is fixedly connected to the top of the base 1, and the upper end of the spring 5 is fixedly connected to the bottom of the guide sleeve 3. During the stamping process, the spring 5 can absorb the impact force to prevent the mold structure from being damaged.

[0016] The inner wall of the oil storage chamber 6 is a columnar structure, and the outer wall of the piston head 7 contacts the inner wall of the oil storage chamber 6. The oil storage chamber 6 is used to store lubricating oil, and the piston head 7 is responsible for moving in the oil storage chamber 6 to push out the lubricating oil. The close contact between the cylindrical inner wall and the outer wall of the piston head 7 ensures the sealed storage and stable flow of the lubricating oil, and prevents leakage of the lubricating oil.

[0017] The dual-axis motor 9 is fixedly connected to the main shaft through the output ends on both sides thereof, and the opposite ends of the two main shafts are fixedly connected to the opposite sides of the two screw rods 10 respectively, and the opposite sides of the two screw rods 10 are movably connected to the bearings fixedly installed in the center of both sides of the installation cavity 8 respectively. The dual-axis motor 9 drives the main shaft to rotate, and then drives the screw rod 10 to rotate. The screw rod 10 is connected to the installation cavity 8 through the bearing, ensuring the stability and durability of the rotation.

[0018] The opposite ends of the four push rods 12 arranged on both sides respectively penetrate into the interior of the two oil storage chambers 6 and are fixedly connected to the opposite sides of the two piston heads 7 respectively. The push rods 12 serve as transmission components to convert the rotational motion of the screw rod 10 into linear motion of the piston head 7.

[0019] Slide grooves are provided on both sides of the top and bottom of the installation cavity 8, and sliders 13 are fixedly connected to the top and bottom of the two moving blocks 11. The four sliders 13 arranged up and down are respectively slidably connected to the four slide grooves to ensure the smooth movement of the moving blocks 11 in the installation cavity 8.

[0020] The lower ends of the four oil spray heads 18 penetrate into the interior of the four guide sleeves 3 respectively. An oil spray hole is opened at the bottom of the outer wall of the oil spray head 18. The number of oil spray holes is several. The oil spray head 18 is designed to spray the lubricating oil accurately and evenly to the parts that need lubrication. The setting of the oil spray holes ensures the uniform distribution of the lubricating oil and improves the lubrication effect. The oil spray head 18 penetrates the interior of the guide sleeve 3, so that the lubricating oil can directly act on the surface of the guide mechanism, thereby achieving effective lubrication of the mold guide mechanism.

[0021] Working principle: when the guide wire mechanism of the stamping die needs to be lubricated, the dual-axis motor 9 is controlled to drive the two screws 10 to rotate at the same time. During the rotation of the two screws 10, the two moving blocks 11 respectively drive the two push rods 12 on both sides to move opposite to each other at the same time. The two push rods 12 simultaneously push the piston heads 7 inside the two oil storage chambers 6 to move opposite to each other. The lubricating oil in the oil storage chamber 6 is pushed by the piston head 7 to pass through the oil outlet pipe 15, the telescopic pipe 16 and the diverter pipe 17 respectively, and finally the lubricating oil is injected into the interior of the guide sleeve 3 through the oil injection hole on the oil injection head 18, which is easy to operate.

[0022] To sum up: the automobile top side beam inner plate stamping die, through the design of the oil storage chamber 6, piston head 7, dual-axis motor 9, screw 10, moving block 11, push rod 12, oil outlet pipe 15, telescopic tube 16, diverter pipe 17 and oil spray head 18, uses the dual-axis motor 9 to drive the screw 10 to rotate, and then the moving block 11 and the push rod 12 drive the piston head 7 to move in the oil storage chamber 6, so as to realize the one-time injection of lubricating oil into the inner wall of each guide sleeve 3 through the oil outlet pipe 15, telescopic tube 16, diverter pipe 17 and oil spray head 18 respectively. This design not only simplifies the lubrication operation and reduces the workload of the staff, but also ensures the uniformity and sufficiency of lubrication by injecting lubricating oil at one time, effectively improving the service life and stamping quality of the mold. At the same time, the oil spray head 18 also makes the lubrication operation more precise and efficient, ensures the uniform distribution of lubricating oil, and avoids the problem of insufficient or excessive lubrication.
