Referring to fig. 6, the sliding block 22 is slidably connected to a liquid collecting bucket 11, the liquid collecting bucket 11 is fixedly connected to the machine body 1, the liquid collecting bucket 11 is in a bucket shape, the lowest end of the liquid collecting bucket 11 is located on one side, close to the oil storage tank 4, of the sliding block 22, the lowest end of the liquid collecting bucket 11 is connected to a liquid through pipe 12 communicated with the inside of the liquid collecting bucket 11, the lower end of the liquid through pipe 12 is connected to a circulating pipe 13, and the circulating pipe 13 is connected to the upper end of the oil.

Referring to fig. 7, the upper end of the oil storage tank 4 is fixedly connected with a tank cover, one side of the tank cover is hinged with a dustproof cover, a handle is fixedly connected with the dustproof cover, and an operator can add lubricating oil into the oil storage tank 4 by rotating the dustproof cover. The second filter 44 is connected to the inside of the oil storage tank 4, the circulation pipe 13 introduced into the inside of the oil storage tank 4 is located inside the second filter 44, and one end of the hydraulic pump 43 located inside the oil storage tank 4 is also located inside the second filter 44.

The implementation principle of the embodiment is as follows: before the punching machine works, an operator injects lubricating oil into the oil storage tank 4, injects cold water into the annular cooling box 45, adjusts the control valve 410 to enable the lubricating oil in the oil storage tank 4 to flow into the oil storage part 33, and then starts the blower 5 and the hydraulic pump 43, the direction of the air opening of the blower 5 can be properly adjusted, and the cold air flow blown by the blower 5 can be blown onto the concave die plate 32. Then, an operator places a workpiece to be processed on the concave template 32, presses the pedal, and the pedal controls the clutch to enable the sliding block 22 to move downwards, and the gravity block 25 is driven to move upwards in the process of moving the sliding block 22 downwards, so that the gravity block 25 is far away from the oil storage part 33. Meanwhile, the connecting element 231 pulls the twisting valve 421 to communicate the atomizing nozzle 420 with the oil return pipe 42, but at this time, since there is no lubricating oil in the oil return pipe 42, the atomizing nozzle 420 cannot spray the lubricating oil.

After the slide block 22 moves downwards, the male die part 21 is abutted to the workpiece to be machined, and the male die part is matched with the female die plate 32 to punch the workpiece to be machined into a preset shape. The slide 22 is then moved upwards, bringing the male mould part 21 away from the female mould plate 32 and the operator takes the machined workpiece out of the female mould plate 32. During the upward movement of the slide block 22, the gravity block 25 moves downward and abuts against the oil reservoir 33, so that the lubricant in the oil reservoir 33 is pushed against the cavity plate 32 and flows along the cavity plate 32. Meanwhile, the pulling force applied to the twisted valve 421 by the connecting member 231 is reduced, and the twisted valve 421 is gradually restored by the pulling force of the restoring elastic member 422, thereby isolating the atomizing nozzle 420 from the oil return pipe 42.

After repeated machining, the lubricating oil in the oil storage 33 continuously flows to the cavity plate 32, and the lubricating oil on the cavity plate 32 flows in a direction away from the oil storage 33 under the influence of the air flow of the blower 5. When an operator places a new workpiece to be machined on the cavity plate 32, lubricating oil is arranged between the workpiece to be machined and the cavity plate 32, so that the machining quality of the workpiece to be machined is ensured. When the lubricant on the cavity plate 32 is too much, the lubricant which is far away from the oil storage 33 preferentially flows into the annular groove 34 and flows into the oil return pipe 42 along the annular groove 34, the lubricant in the oil return pipe 42 flows along the oil return pipe 42 by the suction force of the hydraulic pump 43, and when the atomizing nozzle 420 is communicated with the oil return pipe 42 again, the atomizing nozzle 420 sprays the lubricant into the machine body 1 to lubricate the parts in the machine body. The lubricating oil that is not sprayed to the inside of the machine body 1 by the atomizing nozzle 420 is drawn back into the oil reservoir 4 by the hydraulic pump 43.

The lubricant oil sprayed from the atomizing nozzle 420 toward the inside of the machine body 1 is sprinkled onto the liquid collecting bucket 11, flows along the liquid collecting bucket 11 into the circulating pipe 13, and further flows along the circulating pipe 13 into the oil reservoir 4.

The first filter 350 is periodically disassembled by an operator, impurities on the first filter 350 are cleaned, and the smoothness of the first filter 350 is ensured. After the press is used, the operator cleans the second filter 44. If the amount of lubricating oil in the oil storage tank 4 is insufficient, the operator rotates the dust cap to inject the lubricating oil into the oil storage tank 4.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
