[0025] More specifically, when punch 2 works, the oil collecting plate 1 set on the bottom of punch 2 collects the oil leaked from punch 2, and the oil collecting plate 1 is in the shape of "V", so that it can better guide the oil, and then the oil is concentrated, so that the oil does not flow to other places from the oil collecting plate 1, thereby the oil is preliminarily collected by the oil collecting plate 1, when the oil is collected to a certain amount, the liquid level of the oil reaches the sensing end of the bottom end of the liquid level sensor 4, at this time, the signal is transmitted to the controller 7, the controller 7 indirectly controls the oil discharge assembly, so that the oil leak hole 3 is opened, and the oil flows into the oil receiving box 5, the volume of the oil receiving box 5 is greater than that of the oil collecting plate 1, so that the oil collected in the oil collecting plate 1 can be completely stored, and the controller 7 controls the alarm 8 to alarm, reminding the operator to handle, and the oil receiving box 5 is pulled out from the bottom of the oil collecting plate 1, so that the collected oil is handled, and because the oil receiving box 5 is slidably installed on the bottom of the oil collecting plate 1, it will not interfere with the punch 2.

[0026] Embodiment two: as Figures 2 to 4 shown, on the basis of embodiment one, the top two sides of the oil collecting plate 1 are fixedly connected with the bottom of the punch 2 through the bolts 9, and the oil collecting plate 1 is fixed more firmly through the fixation of multiple groups of bolts 9, so that the oil collecting plate 1 does not fall off due to the increase of the gravity of the oil, the oil leak holes 3 are linearly arranged about the bottom of the oil collecting plate 1, the oil can be quickly leaked through the linearly arranged oil leak holes 3, the oil discharge assembly comprises a threaded rod 10, two threads are formed on the threaded rod 10 and the rotation directions are opposite, the threaded rod 10 is rotatably sleeved on the bottom of the punch 2, one end of the threaded rod 10 is fixedly connected with the output end of the motor 11, and the motor 11 is fixedly installed on one side of the bottom of the punch 2.

[0027] Motor 11 is electrically connected to controller 7. A movable block 12 is symmetrically threaded onto the threaded rod 10. A limit frame 13 is fixedly connected to the top of the movable block 12. A limit rod 14 is slidably connected inside the limit frame 13. Through the sliding connection between the limit rod 14 and the limit frame 13, the movement of the movable block 12 is more stable. Both ends of the limit rod 14 are fixedly connected to the inner wall of the bottom of the stamping machine 2. Both sides of the movable block 12 are rotatably connected to one end of a connecting rod 15 via pins. The other end of the connecting rod 15 is rotatably connected to a connecting seat 16 via a pin. The connecting rod 15 and the connecting seat 16 are connected... 6 is used for the transmission between the moving block 12 and the pressure plate 17. The lower surface of the connecting seat 16 is fixedly connected to the upper surface of the pressure plate 17. The lower surface of the pressure plate 17 is fixedly connected to the pressure frame 18. The bottom of the pressure frame 18 is fixedly connected to the rubber plug 19. The movement of the pressure plate 17 drives the pressure frame 18 to move. The pressure frame 18 then synchronously drives the rubber plug 19, which is fixedly arranged linearly at its bottom, to move. The rubber plug 19 is adapted to the oil leakage hole 3. The two ends of the pressure frame 18 are slidably connected to the side wall of the oil collecting plate 1. The oil collecting plate 1 limits the movement of the pressure frame 18, thereby improving the stability of the movement of the pressure frame 18.

[0028] More specifically, when the oil collected on the oil collecting plate 1 reaches a certain height, it will contact the sensing end at the bottom of the liquid level sensor 4. At this time, the controller 7 receives a signal and controls the motor 11 to rotate. The motor 11 then drives the threaded rod 10 to rotate. Under the rotation of the threaded rod 10, the symmetrically sleeved moving blocks 12 on it are driven to move. The moving blocks 12 move in opposite directions under the limitation of the limiting frame 13 and the limiting rod 14. Thus, through the rotational connection between the connecting rod 15, the connecting seat 16, and the pin, the connecting rod 15 pulls the pressure plate 17 upward, pressing... Plate 17 drives the pressure frame 18 to slide upward under the limit of the oil collecting plate 1, and then the pressure frame 18 drives the rubber plug 19 to be pulled out from the oil leakage hole 3, so that the oil is discharged downward through the oil leakage hole 3 and seeps into the oil collection box 5, thereby further collecting and storing the oil. The volume of the oil collection box 5 is larger than that of the oil collecting plate 1, so it can completely contain the oil. Then, the operator only needs to pull the oil collection box 5 out from the bottom of the oil collecting plate 1. At the same time, since the oil collection box 5 is slidably installed at the bottom of the oil collecting plate 1, there will be no interference with the stamping machine 2.

[0029] Example 3: Figures 3 to 5 As shown, based on Embodiment 2, the liquid level sensor 4, the oil receiving box 5, the controller 7, and the alarm 8 are all fixedly installed on the bottom side wall of the stamping machine 2. Grooves 20 are provided on both sides of the lower surface of the oil collecting plate 1. A limit strip 21 is slidably connected in the groove 20. The bottom of the limit strip 21 is fixedly connected to the oil receiving box 5. A limit block 22 is fixedly connected to one side wall of the oil collecting plate 1. The limit block 22 limits the oil receiving box 5.

[0030] More specifically, when the controller 7 receives the liquid level sensor 4 signal, the controller 7 controls the alarm 8 to issue an alarm at the same time, reminding the operator that the oil collection is full, thereby achieving the purpose of reminding the operator, and then the operator pulls the oil receiving box 5 out from the bottom of the oil collecting plate 1 through the sliding cooperation of the limiting strip 21 and the groove 20, thereby facilitating the operator to handle the oil, avoiding the overflow and waste of the oil.

[0031] Working principle: when the punch 2 is working, the oil seepage from the punch 2 is collected by the oil collecting plate 1 arranged at the bottom of the punch 2, and the oil collecting plate 1 is in the shape of "V", so that the oil can be better guided, thereby making the oil concentrate, and then the oil is preliminarily collected by the oil collecting plate 1, when the oil collected by the oil collecting plate 1 reaches a certain height, the sensing end at the bottom of the liquid level sensor 4 will be contacted, at this time, the controller 7 receives the signal, and the controller 7 indirectly controls the oil leakage assembly, so that the oil leakage hole 3 is opened, so that the oil is discharged downward through the oil leakage hole 3, and the oil seeps into the oil receiving box 5, thereby further collecting and storing the oil, the volume of the oil receiving box 5 is greater than that of the oil collecting plate 1, so that the oil can be completely contained, and then the operator only needs to pull out the oil receiving box 5 from the bottom of the oil collecting plate 1, at the same time, because the oil receiving box 5 is slidably installed at the bottom of the oil collecting plate 1, so that the interference with the punch 2 will not occur, the controller 7 controls the alarm 8 to issue an alarm at the same time, reminding the operator that the oil collection is full, thereby achieving the purpose of reminding the operator, and then the operator pulls the oil receiving box 5 out from the bottom of the oil collecting plate 1 through the sliding cooperation of the limiting strip 21 and the groove 20, thereby facilitating the operator to handle the oil, avoiding the overflow and waste of the oil.
