Description

Technical Field

[0001] The invention relates to the technical field of screw processing, and in particular to an automatic slag removal and anti-loosening threaded screw thread rolling machine. Background Art

[0002] As a common and very important mechanical part, screws play a powerful role in various production and processing. The processing of screws is generally divided into thread drawing, heading, and thread rolling, and then external treatment is performed to ensure the service life of the screws. The screws that have been headed need to be threaded, and the screws are threaded by moving two thread rolling plates against each other. When thread rolling is done in the current screw factory, the screws and iron filings are mixed together, and they are generally screened out manually, but it is not easy to clean up, and it is time-consuming and laborious. On the other hand, some iron filings may be on the thread rolling plate and are not stripped off, affecting subsequent work.

[0004] Although the above scheme can clean up the residual debris on the thread rolling plate in time, there are fewer debris remaining on the thread rolling plate of the existing screw thread rolling machine, and most of the debris falls on the lower part of the screw thread rolling machine. In addition, coolant is required when processing screws. In addition to metal debris, coolant also falls to the bottom of the screw thread rolling machine. In the prior art, filtering is mostly performed through a filter net, but the metal debris and coolant cannot be completely separated. In addition, the metal debris intercepted by the filter net is prone to hooking on the filter net during subsequent removal and cleaning, which is not conducive to subsequent cleaning work. Summary of the invention

[0005] In view of the above problems, an automatic slag removal and anti-loosening threaded screw rolling machine is provided. By arranging a separation device, the cut metal chips and the coolant fall on the filter part of the separation device together. After the filter part receives the coolant and the metal chips, the separation device generates a top-down wind force through the suction part to suck the coolant attached to the metal chips to the bottom of the separation device, while the metal chips still remain on the upper part of the filter part. When the suction part is started, the filter part drives the received metal chips along the length direction of the outer shell to move toward one end of the outer shell. The suction part sucks the coolant on the filter part during the movement of the filter part, thereby achieving the separation of metal chips and coolant, and preventing the metal chips from falling into the bottom of the outer shell.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1 and Figure 2 : An automatic slag removal and anti-loosening threaded screw rolling machine, including a shell 3 and a rolling device 1 arranged on the shell 3; the screw rolling machine also includes a separation device 2, the separation device 2 is arranged below the rolling device 1, the separation device 2 includes a filtering part and a suction part arranged vertically from top to bottom, the filtering part receives the fallen metal debris, and then the suction part generates a top-down wind force to suck the coolant attached to the metal debris into the bottom of the shell 3.

[0034] The outer periphery of the thread rolling device 1 is provided with a shell 3 for supporting the operation of the thread rolling device 1. The separation device 2 is located inside the shell 3. An opening is provided at the upper part of the shell 3. The separation device 2 can generate an airflow flowing from top to bottom along the height direction of the shell 3. The thread rolling device 1 needs to use coolant for cooling and lubrication when rolling the screws. The cut metal debris falls on the filter part of the separation device 2 together with the coolant. After the filter part receives the coolant and the metal debris, the separation device 2 generates a top-down wind force through the suction part to suck the coolant attached to the metal debris to the bottom of the separation device 2, while the metal debris still remains in the upper part of the filter part. When the suction part is started, the filter part drives the received metal debris to move toward one end of the shell 3 along the length direction of the shell 3. The suction part sucks the coolant on the filter part during the movement of the filter part, thereby realizing the separation of metal debris and coolant, and avoiding the situation where the metal debris falls into the bottom of the shell 3.

[0035] Reference Figure 2-Figure 4The filtering part comprises a conveyor belt 21, which is an annular structure for receiving metal scraps and is horizontally rotatably arranged at the lower part of the thread rolling device 1. The conveyor belt 21 is an annular belt with uniform filtering holes.

[0036] The conveyor belt 21 is provided with a driving device 22 for driving the conveyor belt 21 to rotate. The driving device 22 includes a driving wheel 221 and a rotating driver 222. Two driving wheels 221 are provided. The two driving wheels 221 are arranged along the length direction of the housing 3. The two ends of the conveyor belt 21 are respectively sleeved on the two driving wheels 221. The driving wheels 221 are matched with the conveyor belt 21 for transmission. The rotating driver 222 is fixedly arranged at one end of the driving wheel 221. The rotating driver 222 is preferably a servo motor. When the rotating driver 222 is started, the driving wheel 221 can drive the conveyor belt 21 to rotate, so that the conveyor belt 21 can drive the falling objects on the upper part thereof. The metal debris is moved and discharged along the length direction of the shell 3, and the conveyor belt 21 is an endless belt with uniform filtering holes. When the suction device 23 sucks the conveyor belt 21, the air on the conveyor belt 21 can pass through the conveyor belt 21 from top to bottom, so that the coolant remaining on the conveyor belt 21 and the metal debris are driven into the separation chamber by the flowing air, and the metal debris is blocked by the conveyor belt 21, thereby realizing the separation of the metal debris and the coolant. At the same time, since the conveyor belt 21 is made of rubber, the metal debris is not easy to hook the conveyor belt 21, and the metal debris and the coolant are collected separately during separation, thereby improving the work efficiency.

[0037] Reference Figure 3 The suction part includes a suction device 23, which is arranged in the inner ring of the conveyor belt 21. The upper part of the suction device 23 is a suction end and is attached to the upper side of the conveyor belt 21. The suction device 23 can drive the air to flow from top to bottom.

[0038] Reference Figure 4 and Figure 5 The suction device 23 includes a gas-liquid separation unit 231, which constitutes a separation chamber. The gas-liquid separation unit 231 is provided with a fan 2311 for extracting the gas in the separation chamber. The fan 2311 is located on the side of the suction device 23. The coolant sucked into the separation chamber falls to the bottom of the separation chamber under the action of its own gravity.

[0039] The gas-liquid separation unit 231 includes a separation chamber 2313 , which constitutes a separation cavity. The fan 2311 is disposed on a side wall of the separation chamber 2313 .

[0040] Reference Figure 5 : An automatic drainage unit 232 is arranged at the bottom of the separation chamber, and the automatic drainage unit 232 controls the liquid level of the coolant in the separation chamber to always be lower than the fan 2311.

[0041] Reference Figure 5 and Figure 8 : A pressure-holding unit 233 is provided at the lower part of the separation chamber, and the automatic drainage unit 232 separates the pressure-holding unit 233 and the separation chamber. The pressure-holding unit 233 constitutes a pressure-holding chamber. When the automatic drainage unit 232 is opened to discharge the coolant in the separation chamber into the pressure-holding chamber, the pressure-holding chamber is in a sealed state. When the automatic drainage unit 232 is closed, the pressure-holding chamber is in an open state.

[0042] If the pressure-holding chamber is always in a sealed state, as the automatic drainage unit 232 is continuously opened, the pressure-holding chamber will eventually be filled with coolant. After the pressure-holding chamber is filled, although the fan 2311 can suck the coolant on the conveyor belt 21 through the separation chamber, the liquid level of the coolant at the bottom of the separation chamber will continue to rise, and finally the coolant in the separation chamber rises to the position of the fan 2311. Such a large amount of coolant rushes to the position of the fan 2311, which can easily cause the fan 2311 to be damaged by the coolant. In this way, the pressure-holding chamber needs to discharge the stored coolant regularly. It is worth noting that when the automatic drainage unit 232 switch is turned on, the pressure-holding chamber is in a sealed state. At this time, the coolant in the separation chamber passes through The automatic drainage unit 232 flows into the pressure holding chamber, but the pressure holding chamber is in a sealed state. As the coolant in the separation chamber enters the pressure holding chamber, the air in the pressure holding chamber can also enter the separation chamber through the automatic drainage unit 232 and be discharged by the fan 2311. However, since the pressure holding chamber is in a sealed state, the fan 2311 cannot obtain a steady supply of air from the pressure holding chamber. In this way, the negative pressure in the separation chamber will adsorb the conveyor belt 21, ensuring that the fan 2311 can form enough negative pressure on the separation chamber when the automatic drainage unit 232 is turned on, so that the coolant on the conveyor belt 21 can be sucked into the separation chamber. It is worth noting that when the automatic drainage unit 232 is turned on and the pressure holding chamber is in a sealed state. , the air in the pressure-maintaining chamber can flow into the separation chamber through the automatic drainage unit 232. At this time, the negative pressure in the separation chamber decreases. However, since the air stored in the pressure-maintaining chamber is limited, even if the negative pressure decreases, the adsorption function of the fan 2311 for the conveyor belt 21 is still effective. If the pressure-maintaining unit 233 is not provided, when the automatic drainage unit 232 drains water, the outside air flows into the separation chamber from the automatic drainage unit 232, thus making the suction function of the fan 2311 invalid. The fan 2311 cannot suck the air above the conveyor belt 21 into the separation chamber, thus failing to effectively separate the metal scraps and the coolant on the conveyor belt 21. The pressure-maintaining unit 233 includes a pressure-maintaining chamber 2331. and the first switch valve 2332, the pressure holding chamber 2331 is arranged at the bottom of the automatic drainage unit 232, the first switch valve 2332 is arranged on the side wall of the pressure holding chamber 2331, the opening and closing of the pressure holding chamber formed by the pressure holding unit 233 is controlled by the first switch valve 2332, when the first switch valve 2332 is opened, the pressure holding chamber is in an open state, when the first switch valve 2332 is closed, the pressure holding chamber is in a closed state, when the first switch valve 2332 is opened, the coolant in the pressure holding chamber 2331 flows out and falls into the bottom of the outer shell 3, a circulation device is arranged at the bottom of the outer shell 3, the circulation device performs secondary filtration on the coolant, and then reintroduces it into the upper part of the outer shell 3 and sprays it on the screws being processed.

[0043] Reference Figure 5-Figure 8The automatic drainage unit 232 includes a partition plate 2323, which is horizontally arranged between the separation chamber and the pressure maintaining chamber to separate the two. A discharge port 2324 is vertically penetrated through the partition plate 2323. A floating member 2321 that moves in the vertical direction and a switch plate 2322 that moves in the horizontal direction to control the switch of the discharge port 2324 are provided on the partition plate 2323. When the floating member 2321 is at the lower stop position of its own moving stroke, the switch plate 2322 is completely closed.

[0044] The float 2321 does not have a fixed upper stop position. This is because the amount of coolant sucked into the separation chamber by the fan 2311 cannot be guaranteed to remain at a constant value. In this way, the coolant at the bottom of the separation chamber will lift up the float 2321 after accumulating too much. The switch plate 2322 is turned on, and as the coolant is discharged, the float 2321 will fall again. There must be a difference in the height to which the float 2321 floats each time. Therefore, the float 2321 does not have a fixed upper stop position, but the lower stop position of the float 2321 is fixed. When the amount of coolant in the separation chamber is small, the float 2321 is supported by the partition plate 2323, so that the float 2321 no longer falls, and the upper part of the discharge port 2324 is located below the lower stop position of the float 2321, that is, When the floating member 2321 drops to the lower stop position, it means that the amount of coolant stored in the separation chamber is small. At this time, the floating member 2321 is supported by the partition plate 2323, and the floating member 2321 will no longer drop along the height direction of the shell 3. At this time, the liquid level in the separation chamber is above the discharge port 2324, and when the floating member 2321 drops to the lower stop position, the switch plate 2322 closes the switch port. At this time, the remaining coolant in the separation chamber cannot be discharged from the discharge port 2324 into the pressure holding chamber 2331, so the separation chamber is self-sealed. If the lower stop position of the floating member 2321 is lower than or equal to the upper height of the discharge port 2324, the pressure holding chamber is likely to be in a continuously open state, and the outside air can flow back into the pressure holding chamber 2331 through the discharge port 2324 through the pressure holding chamber 2331. In the separation chamber, the negative pressure in the separation chamber is sharply reduced and the conveyor belt 21 cannot be sucked, so that the coolant attached to the metal debris on the conveyor belt 21 cannot be sucked, which leads to the situation that some metal debris and the coolant cannot be separated. The upper part of the discharge port 2324 is set below the lower stop position of the floating member 2321, which ensures that the bottom of the separation chamber is always in a liquid-sealed state, thereby ensuring the negative pressure strength in the separation chamber. A transmission assembly is set between the floating member 2321 and the switch plate 2322. When the floating member 2321 is lifted in the vertical direction, the switch plate 2322 is driven to move by the transmission assembly. The transmission assembly includes a lifting rod 2325 and a connecting rod 2326. A working chamber is set in the partition plate 2323. The rod 2325 vertically penetrates the upper part of the partition plate 2323 and extends into the working chamber. The upper part of the lifting rod 2325 is fixedly connected to the bottom of the floating member 2321. The switch plate 2322 is located on the side of the lifting rod 2325. The two ends of the connecting rod 2326 are hinged to the switch plate 2322 and the bottom of the lifting rod 2325 respectively. When the floating member 2321 descends, the floating member 2321 drives the switch plate 2322 to move and block the discharge port 2324 through the extension rod and the connecting rod 2326, so that the coolant in the separation chamber cannot enter the pressure holding chamber 2331. When the floating member 2321 rises, the floating member 2321 drives the switch plate 2322 to move and make way for the discharge port 2324 through the extension rod and the connecting rod 2326.At this time, the coolant in the separation chamber can be discharged from the discharge port 2324 into the pressure-maintaining chamber 2331. A second switch valve 2327 is provided at the lower part of the fan 2311. The second switch valve 2327 is provided on the side wall of the separation chamber 2313. After the screw thread rolling machine completes the processing, the second switch valve 2327 is opened to discharge all the coolant remaining in the separation chamber. A photoelectric sensor 2328 with a monitoring end facing vertically downward is provided at the bottom of the lifting rod 2325. The photoelectric sensor 2328 rises and falls synchronously with the lifting rod 2325 and monitors the distance between the bottom of the lifting rod 2325 and the bottom of the working chamber. When the distance monitored by the photoelectric sensor 2328 reaches the preset minimum distance, the floating plate reaches the lower stop position at this time, and the first switch valve 2332 is opened. Otherwise, the first switch valve 2332 is closed.

[0045] Reference Figure 5 A cover shell 2312 is provided on the suction end of the fan 2311, and the opening of the cover shell 2312 is arranged downward.

[0046] The suction end of the fan 2311 faces the separation chamber, and the fan 2311 draws out the air in the separation chamber to form a negative pressure in the separation chamber, so that the outside air passes through the conveyor belt 21 and enters the separation chamber. In the process of the outside air passing through the conveyor belt 21 and entering the separation chamber, the coolant remaining on the metal debris can be brought into the separation chamber. The coolant entering the separation chamber falls to the bottom of the separation chamber under the action of the airflow and its own gravity. By setting a cover 2312 at the suction end of the fan 2311, under the influence of the airflow of the fan 2311, some smaller coolant droplets still enter the fan 2311 from the suction end of the fan 2311, but a small amount of coolant has little effect on the normal operation of the fan 2311, thereby avoiding the situation where a large amount of coolant enters the fan 2311 and affects the fan 2311.

[0047] Reference Figure 8-Figure 10 A supporting device 24 for supporting the conveyor belt 21 is provided on the suction end of the suction device 23.

[0048] The supporting device 24 includes a guide rail 241 and a support rod 242. Two guide rails 241 are provided. The two guide rails 241 are arranged on the upper part of the suction device 23 along the length direction of the shell 3 and the two guide rails 241 are symmetrically arranged. When the conveyor belt 21 rotates to the upper side to receive the metal scraps, it can rotate into the two guide rails 241. The two guide rails 241 support both sides of the conveyor belt 21. There is a gap between the two guide rails 241. The support rod 242 is arranged in the gap along the width direction of the shell 3 and the two ends of the support rod 242 are fixedly connected to the two guide rails 241. The support rods 242 are arranged in the gap along the length direction of the outer shell 3, and the support rods 242 support the conveyor belt 21. This is because after the suction device 23 generates suction on the conveyor belt 21, if there is no support from the support rods 242, the conveyor belt 21 is prone to deformation, which can easily cause metal debris on the conveyor belt 21 to fall into the separation chamber. A guide shell 25 is provided on the upper part of the guide rail 241, and the upper opening of the guide shell 25 is larger than the lower opening of the guide shell 25. Under the guidance of the guide shell 25, the metal debris can accurately fall on the conveyor belt 21.

[0049] Reference Figure 2 and Figure 3 An inclined abutment plate 26 is provided at one end of the conveyor belt 21 in the horizontal direction. The abutment plate 26 abuts against the end of the conveyor belt 21 and scrapes off metal debris on the rotating conveyor belt 21.

[0050] The abutment plate 26 always abuts against one end of the conveyor belt 21 . When the conveyor belt 21 rotates, the inclined abutment plate 26 faces the end of the conveyor belt 21 and can scrape off metal scraps on the conveyor belt 21 .

[0051] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
