Description

Technical Field

[0001] The present invention belongs to the technical field of stamping equipment, and in particular relates to a connecting rod slider oil retaining mechanism, a lubricating oil recycling device and stamping equipment. Background Art

[0002] Stamping equipment is a versatile press with a sophisticated structure. It has a wide range of uses and high production efficiency. It can be widely used in cutting, punching, blanking, bending, riveting and forming processes. Stamping equipment applies strong pressure to metal blanks to cause plastic deformation and fracture of the metal to form parts. Figure 10-13 As shown in the figure, the key components of traditional mechanical stamping equipment include the crankshaft, connecting rod, and slider. The crankshaft is an eccentric shaft that rotates axially, driving the connecting rod and slider up and down. The connecting rod ball head is pressed by the ball socket and ball sleeve and installed in the slider guide pin (two sets). The slider guide pin is bolted to the slider. The slider guide sleeve contains a copper sleeve fixed to the machine bed. Driven by the two connecting rods, the slider follows the guide pin and slides up and down within the guide sleeve copper sleeve. The slider guide sleeve copper sleeve has an oil groove inside and an oil filler port on the side wall. During normal production, the slider guide pin slides within the slider guide sleeve, requiring regular and quantitative lubrication to protect the guide pin and sleeve from wear.

[0003] The slider guide sleeve has a protective cover underneath, which contains an oil seal to prevent the lubricant from flowing downward. A dust cover protects the oil seal. Although the original slider guide sleeve had a protective cover at the bottom, containing an oil seal and a dust ring outside the oil seal, lubricant could still leak between the slider guide post and the guide sleeve during production due to excessive lubricant or aging of the oil seal. This oil then leaks along the slider and onto the mold below, contaminating the mold and the product mounted on it. Furthermore, the rapid up-and-down motion of the slider can cause the lubricant to splash even further, severely impacting the production environment. Replacing this oil seal requires disassembling the entire connecting rod slider, a labor-intensive and time-consuming process that impacts the efficiency of the stamping equipment. Although some stamping equipment manufacturers currently manufacture various oil collection boxes under the slider, these still do not effectively address the issue of lubricant contamination. Summary of the Invention

[0004] The purpose of the present invention is to provide a connecting rod slider oil baffle mechanism, a lubricating oil recycling device and a stamping equipment. The connecting rod slider oil baffle mechanism can collect the leaked lubricating oil, and the lubricating oil recycling device can separate the collected lubricating oil into oil and gas, thereby achieving the purpose of recycling the lubricating oil and solving the problem of lubricating oil pollution.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows: In the first aspect, the present invention discloses a connecting rod slider oil baffle mechanism, which is sleeved on the slide rail guide column and includes an oil baffle plate sleeved on the slide rail guide column, the oil baffle plate includes an oil baffle horizontal ring and an oil baffle vertical ring, the oil baffle horizontal ring and the oil baffle vertical ring form an L-shaped cross-section structure, an oil suction piece is provided on the inner ring of the oil baffle horizontal ring, a transverse oil suction through hole is opened on the oil baffle horizontal ring, one end of the transverse oil suction through hole is connected to the oil suction piece, and the other end of the transverse oil suction through hole is connected to the negative pressure suction pipe.

[0006] Furthermore, the oil baffle plate includes a first oil baffle plate and a second oil baffle plate that are hinged to each other. The first oil baffle plate is provided with a first negative pressure suction pipe assembly, and the second oil baffle plate is provided with a second negative pressure suction pipe assembly. The movable ends of the first oil baffle plate and the second oil baffle plate are provided with locking members for locking the first oil baffle plate and the second oil baffle plate. With such a configuration of the present technical solution, during installation, the first and second oil baffle plates can be unfolded, placed on the guide posts of the slide rail, and then closed and locked using the locking members, making installation and removal very convenient.

[0007] Furthermore, the first and second negative pressure suction pipe assemblies have the same structure, both comprising a suction pipe body, each with a first connecting piece provided at both ends of the suction pipe body, and a three-way valve provided in the middle of the pipe body. The first and second oil baffle plates are each provided with two transverse oil suction holes, and the first connecting pieces at both ends of the pipe body are connected to the two transverse oil suction holes in the first and second oil baffle plates, respectively. This allows multiple transverse oil suction holes to be provided on the oil baffle plates, improving the adsorption and collection of lubricating oil flowing into the oil baffle plates.

[0008] Furthermore, an L-shaped groove is provided at one end of the oil-blocking horizontal ring away from the oil-blocking vertical ring, and the oil-absorbing member is an oil-absorbing cotton, which is embedded in the L-shaped groove. The oil-absorbing cotton has a good oil-absorbing effect, and being embedded in the L-shaped groove of the oil-blocking horizontal ring makes it easy to replace.

[0009] In the second aspect, the present invention also discloses a lubricating oil circulation device, including the above-mentioned connecting rod slider oil baffle mechanism, and a first box body and a second box body arranged in an overlapping manner up and down, a partition is provided between the first box body and the second box body, the partition is provided with an oil drain hole and a second connecting piece connecting the first box body and the second box body, the second box body is provided with an oil suction pipe opening, an air inlet pipe opening and an oil drain opening, the oil suction pipe opening is connected to the negative pressure suction pipe, an air inlet pipe connected to the air inlet pipe opening is provided in the second box body, the end of the air inlet pipe away from the air inlet pipe opening is connected to a vacuum suction piece, the outlet end of the vacuum suction piece is connected to an oil drain pipe, the oil suction pipe opening is connected to an oil suction pipe, the oil suction pipe is connected to the vacuum suction piece; the end of the oil drain pipe away from the vacuum suction piece is connected to the second connecting piece; an exhaust pipe is provided on the first box body, and a baffle is provided in the first box body at the exhaust pipe.

[0010] Furthermore, the second connecting piece is a muffler, which is made of copper and has a height of 25-35 mm. The second connecting piece of this technical solution is a muffler. The muffler not only disperses the oil and gas, achieving a better separation effect, but also reduces the noise of the high-speed oil and gas flow as the oil and gas pass through the muffler. Furthermore, according to tests, the copper muffler has a better oil and gas dispersion effect than mufflers made of other materials (such as rubber mufflers). Furthermore, the copper muffler can be 25-35 mm high. This shorter height avoids the problem of the muffler blocking the oil and gas rotation separation as the oil and gas pass through the muffler, resulting in a better separation effect.

[0011] Furthermore, a connecting channel is provided in the vacuum suction member, the inlet of the connecting channel is a compressed air inlet, the air inlet pipe is connected to the compressed air inlet, the outlet of the connecting channel is an air outlet, the air outlet is connected to the oil drain pipe, a nozzle is provided in the connecting channel with the spraying direction aligned with the air outlet, a vacuum suction port is provided on the vacuum suction member located in the spraying direction of the nozzle, and the vacuum suction port is connected to the oil suction pipe. The present technical solution is configured in such a way that the air inlet port on the second box body is connected to an external compressed air source, and the compressed air enters the connecting channel from the compressed air inlet on the vacuum suction member at high speed, and is ejected from the nozzle at high speed, thereby forming a local vacuum at the outlet of the nozzle, that is, a vacuum is formed at the vacuum suction port. Because the vacuum suction port is connected to the oil suction pipe, a vacuum will be formed at the oil suction pipe port. The oil suction pipe port can generally be connected to the oil leakage part that needs to be sucked through an external pipeline, and the oil leaked from the equipment is absorbed into the oil suction pipe through negative pressure, and finally forms oil gas together with the compressed air ejected from the nozzle, and enters the oil discharge pipe through the air outlet; thereby achieving the purpose of oil suction.

[0012] Furthermore, the second housing has a conical structure that is larger at the top and smaller at the bottom, and the oil drain port is located at the conical bottom of the second housing. With this arrangement, when the liquid oil after oil and gas separation enters the bottom of the conical second housing, it flows out of the oil drain port and can flow back into the oil tank of the equipment through the pipeline.

[0013] Furthermore, the second housing is provided with two vacuum suction members, located on either side of the second housing. Four second connecting members are installed in a square array on the partition. A tee is provided on the oil drain pipe, the outlet of which is connected to the second connecting member. This arrangement allows the oil-gas separation device of the present invention to be more efficient and compact.

[0014] In a third aspect, the present invention further discloses a stamping device, which includes a device body and the above-mentioned connecting rod slider oil retaining mechanism, or the above-mentioned lubricating oil recycling device.

[0015] The invention adopting the above technical solution has the following advantages: 1. The connecting rod slider oil baffle mechanism of the present invention is sleeved on the slide rail guide column. When the lubricating oil leaked from the slide rail guide rail flows down from top to bottom, the oil baffle plate can catch the leaked lubricating oil, and then enter the oil baffle plate. Because the oil baffle plate is provided with an oil suction piece, the lubricating oil can be sucked out first, and the negative pressure suction pipe of the external negative pressure adsorption device sucks the lubricating oil adsorbed on the oil suction piece out through negative pressure, and enters the lubricating oil recycling device of the present invention for oil-gas separation. During the whole process, the leaked lubricating oil can basically be absorbed and collected, solving the problem of lubricating oil polluting the working environment and products.

[0016] 2. The air inlet on the second box of the present invention is connected to the external compressed air. The compressed air enters the connecting channel from the compressed air inlet on the vacuum suction member at high speed and is ejected from the nozzle at high speed, thereby forming a local vacuum at the outlet of the nozzle, that is, forming a vacuum at the vacuum suction port. Because the vacuum suction port is connected to the oil suction pipe, a vacuum will be formed at the oil suction pipe port. The oil suction pipe port can generally be connected to the oil leakage part that needs to be sucked through an external pipeline, so that the oil leaked from the equipment is absorbed into the oil suction pipe through negative pressure, and finally combined with the compressed air ejected from the nozzle The oil and gas are combined to form oil and gas, which enter the oil drain pipe through the air outlet; the oil and gas then enter the muffler through the oil drain pipe, and after silencing and preliminary oil and gas separation, they enter the first box for oil and gas separation, and the liquid lubricating oil flows out from the bottom oil drain port of the conical second box, and can flow back to the oil tank of the equipment through the pipeline, and the separated gas is discharged through the exhaust pipe; the whole process can recycle the lubricating oil leaked from the equipment for reuse; according to production statistics, a piece of equipment originally needed to be replenished with 20 liters of lubricating oil a week, but now it basically does not need to be replenished.

[0017] 3. The present invention is provided with a baffle at the exhaust pipe of the first box body, which can prevent oil and gas from flowing out directly from the exhaust pipe. The baffle and the three side walls of the first box body form a cavity, which can make the oil and gas entering the first box body collide, so that the oil and gas swirl in the first box body, centrifugal rotation and collision, and finally the liquid part of the oil is deposited downward to the bottom of the second box body, and enters the second box body through the oil drain hole, and finally flows out from the bottom oil drain port of the conical second box body, and can flow back to the oil tank of the equipment through the pipeline; according to experiments, the setting of the baffle has a better oil and gas separation effect than not setting the baffle.

[0022] The first negative pressure suction pipe assembly of this embodiment has the same structure as the second negative pressure suction pipe assembly, both including a suction pipe body 7, with first connecting pieces 8 provided at both ends of the suction pipe body 7. The first connecting piece 8 of this embodiment is a threaded pipe, and the transverse oil suction hole can also be provided as a threaded hole, so that the threaded pipe is threadedly connected within the threaded hole; a three-way valve 9 is provided in the middle of the pipe body; two transverse oil suction holes are provided on the first oil baffle plate 4 and the second oil baffle plate 5, respectively. The first connecting pieces 8 at both ends of the pipe body are connected to the two transverse oil suction holes on the first oil baffle plate 4 and the second oil baffle plate 5. Four transverse oil suction holes can be provided on the oil baffle plate to better absorb and collect the lubricating oil flowing into the oil baffle plate.

[0023] like Figure 4-8As shown, the oil-gas separation mechanism includes a first box body 10 and a second box body 11 which are overlapped and fixedly connected with each other by fixing screws. A partition is provided between the first box body 10 and the second box body 11. The partition is provided with an oil drain hole 23 and a second connecting piece 13 which communicate with the first box body 10 and the second box body 11. The second box body 11 is provided with an oil suction pipe port 15, an air intake pipe port 16 and an oil drain port 17. The oil suction pipe port 15 is connected with the three-way valve 9 on the negative pressure suction pipe. An air intake pipe 22 which is connected with the air intake pipe port 16 is provided in the second box body 11. The air intake pipe 22 is far away from the first box body 10 and the second box body 11. One end away from the air inlet pipe port 16 is connected to a vacuum suction part 19, the outlet end of the vacuum suction part 19 is connected to an oil drain pipe 20, the oil suction pipe port 15 is connected to an oil suction pipe 21, and the oil suction pipe 21 is connected to the vacuum suction part 19; the end of the oil drain pipe 20 away from the vacuum suction part 19 is connected to the second connecting part 13; an exhaust pipe 12 is provided on the first box body 10, and a baffle 14 is provided in the first box body 10 at the exhaust pipe 12; in order to facilitate the liquid oil after oil and gas separation to flow back into the oil tank of the equipment, the second box body 11 is a conical structure with a larger upper part and a smaller lower part, and the oil drain port 17 is provided at the cone bottom of the second box body 11.

[0024] like Figure 9 As shown, a connecting channel 25 is provided in the vacuum suction member 19, the inlet of the connecting channel 25 is a compressed air inlet 26, the air inlet pipe 22 is connected to the compressed air inlet 26, the outlet of the connecting channel 25 is an air outlet 27, the air outlet 27 is connected to the oil drain pipe 20, a nozzle 28 is provided in the connecting channel 25, the spraying direction of which is aligned with the air outlet 27, and a vacuum suction port 29 is provided on the vacuum suction member 19 located in the spraying direction of the nozzle 28, and the vacuum suction port 29 is connected to the oil suction pipe 21. The present technical solution is configured in such a way that the air inlet port 16 on the second box body 11 is connected to an external compressed air source, and the compressed air enters the connecting channel 25 from the compressed air inlet 26 on the vacuum suction member 19 at high speed, and is ejected from the nozzle 28 at high speed, thereby forming a local vacuum at the outlet of the nozzle 28, that is, a vacuum is formed at the vacuum suction port 29. Because the vacuum suction port 29 is connected to the oil suction pipe 21, a vacuum will be formed at the oil suction pipe port 15. The oil suction pipe port 15 can generally be connected to the oil leakage part that needs to be sucked through an external pipeline, and the oil leaked from the equipment is absorbed into the oil suction pipe 21 through negative pressure, and finally forms oil gas together with the compressed air ejected from the nozzle 28, and enters the oil discharge pipe 20 through the air outlet 27; thereby achieving the purpose of oil suction. In order to improve the oil and gas separation efficiency, two vacuum suction parts 19 are provided in the second box body 11 of this embodiment. The two vacuum suction parts 19 are located on both sides of the second box body 11. The number of second connecting parts 13 is four. The four second connecting parts 13 are installed on the partition in a square array. A tee pipe 24 is provided on the oil drain pipe 20, and the outlet end of the tee pipe 24 is connected to the second connecting part 13.

[0025] The second connecting piece 13 of this embodiment is a copper muffler, and its height is 25-35mm. The second connecting piece 13 of this technical solution is a muffler. The muffler not only disperses the oil and gas, achieving a better separation effect, but also reduces the noise of the high-speed oil and gas flow as the oil and gas pass through the muffler. Tests have shown that copper mufflers provide better oil and gas dispersion than mufflers made of other materials (such as rubber mufflers, which only work with a height of 70mm). Furthermore, the copper muffler can be 25-35mm high. This shorter height prevents the muffler from obstructing the oil and gas rotational separation as the oil and gas pass through it, resulting in a better separation effect.

[0026] The operating principle of the oil-gas separation device in this embodiment is as follows: During installation, the first oil baffle plate 4 and the second oil baffle plate 5 can be unfolded, placed on the guide column of the slide rail, and then closed and locked with the hose clamp buckle 6. When the lubricating oil leaked from the slide rail flows down from top to bottom, the oil baffle plate can catch the leaked lubricating oil, and then enter the oil baffle plate, because the oil baffle plate is provided with an oil suction member 3 to absorb the lubricating oil first, and the negative pressure suction pipe of the external negative pressure adsorption device sucks the lubricating oil adsorbed on the oil suction member 3 out through negative pressure, and enters the lubricating oil recycling device of the present invention for oil and gas separation. During the whole process, the leaked lubricating oil can be basically all adsorbed and collected.

[0027] The air inlet 16 on the second box body 11 is connected to the external compressed air. The compressed air enters the connecting channel 25 from the compressed air inlet 26 on the vacuum suction member 19 at high speed, and is ejected from the nozzle 28 at high speed, thereby forming a partial vacuum at the outlet of the nozzle 28, that is, a vacuum is formed at the vacuum suction port 29. Because the vacuum suction port 29 is connected to the oil suction pipe 21, a vacuum will be formed at the oil suction pipe port 15. The oil suction pipe port 15 can generally be connected to the oil leakage part that needs to be sucked through an external pipeline, so that the oil leaked from the equipment is absorbed into the oil suction pipe 21 through negative pressure, and finally forms oil gas together with the compressed air ejected from the nozzle 28, and enters the oil discharge pipe 20 through the air outlet 27; the oil gas then passes through the oil discharge pipe 20 enters the muffler, and after silencing and preliminary oil and gas separation, it enters the first box body 10. The high-pressure oil and gas collide on the three side walls and baffle 14 of the first box body 10, causing the oil and gas to swirl in the first box body 10, centrifugal rotation and collision, and finally the liquid part of the oil is deposited downward to the bottom of the second box body 11, and enters the second box body 11 through the oil drain hole 23, and finally flows out from the bottom oil drain port 17 of the conical second box body 11, and can flow back to the oil tank of the equipment through the pipeline, and the separated gas part is discharged through the exhaust pipe 12; the whole process can recycle and reuse the lubricating oil leaked from the equipment, which can not only improve the working environment, but also save the use of lubricating oil.

The description of the specific embodiment is only used to help understand the method and core concept of the present invention.
