[0002] The crankshaft of a punch press is an important part of the punch press bed. It is made of carbon structural steel or ductile iron. It has two important parts: the main journal and the connecting rod journal. The main journal is installed on the bed, the connecting rod journal is connected to the big end hole of the connecting rod, and the small end hole of the connecting rod is connected to the punch press slider. It is a typical crank slider mechanism. The lubrication of the crankshaft mainly refers to the lubrication of the bearing between the rocker arm and the lubrication of the fixed points at both ends. The rotation of the crankshaft is the power source of the punch press and also the source power of the entire mechanical system.
[0003] The existing oil inlet mechanism for lubricating the crankshaft of a punch press is to aim the grease gun at the grease nozzle, squeeze the grease gun to pressurize it, and thus squeeze the grease inside the grease gun into the crankshaft to lubricate the crankshaft and ensure smooth operation of the crankshaft.

Block 11, the slider 11 is slidably connected with a slide rail 12 on one side close to the toothed disc 8, and the slide rail 12 is fixedly connected to the outside of the butter box 3. During operation, when butter needs to be injected, the butter is first injected into the butter box 3 along the injection port 13, and then the drive motor 5 is started. At this time, the drive motor 5 will drive the drive rod 6 to rotate, so that the drive rod 6 can drive the gear 7 to rotate, so that the toothed disc 8 can be driven to rotate smoothly on the top of the butter box 3. When the toothed disc 8 rotates, it will drive the push rod 14 and the push screw 15 to rotate, so that the butter inside the butter box 3 is squeezed into the inside of the push screw 15 along the push screw 15, and then the butter is injected into the bearing along the butter filling pipe 18 17 lubricates the crankshaft body 20. When the lubricant inside the crankshaft body 20 is too much, the slider 11 is moved to slide on the top of the slide rail 12, thereby driving the sliding rod 10 inside the pushing block 9 to move, so that the gear 7 on the right side is engaged with the toothed disc 8, and then the toothed disc 8 can be rotated in the opposite direction without reversing the driving motor 5, so that the butter can move along the pushing spiral 15 to the top of the butter box 3. At this time, the injection port 13 is sealed, so that the air above the butter box 3 is squeezed out along the air filling port 16, so that the air is injected into the bearing 17, so that the excess butter inside the bearing 17 can be squeezed out.

When the lubricant inside the crankshaft body 20 is filled too much, the slider 11 is moved to slide on the top of the slide rail 12, thereby driving the sliding rod 10 inside the pushing block 9 to move, so that the gear 7 on the right side is meshed with the gear plate 8, and then the gear plate 8 can be reversed without the driving motor 5 being reversed, so that the butter can be moved to the top of the butter box 3 along the pushing screw 15, and the injection port 13 is sealed at this time, so that the air above the butter box 3 is filled along the air filling pipe The injection port 16 is squeezed out, thereby injecting air into the bearing 17, so that the excess butter in the bearing 17 can be squeezed out. When the butter is transmitted, the air can enter the butter box 3 along the one-way valve 29, so that the problem of pressure difference in the butter box 3 and the inability to inject butter will not occur. When the air above the butter box 3 needs to be squeezed out, the butter can be pushed along the pushing screw 15 to the top of the butter box 3. At this time, the one-way valve 29 will be sealed to ensure that the air inside the butter box 3 will not leak out. When the butter filling is completed, the equipment can be started for stamping, and the stamping motor 26 is started to drive the crankshaft body 20 to rotate, so that the crankshaft body 20 can drive the sleeve rod 21 to move up and down, and the sleeve rod 21 rotates between the connecting blocks 23 through the connecting shaft 24 when moving up and down, so as to ensure that the stamping plate 25 runs smoothly during extrusion, and when the stamping plate 25 reaches above the stamping motor 26, the raw material can be formed, and the stamping table 27 can support the stamping motor 26 for stable operation to ensure the smooth operation of the stamping table 27.
