[0002] Stamping is a forming method that applies external force to plates, strips, tubes and profiles to make them plastically deform or separate, so as to obtain workpieces of the desired shape and size. It belongs to the same plastic processing as forging, and is collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Most metal products in the world are made by stamping, such as automobile bodies, chassis, fuel tanks, radiators, boiler drums, container shells, iron core silicon steel sheets for motors and electrical appliances, etc.

DETAILED DESCRIPTION

[0030] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] One of the preferred embodiments of the present application is as follows: Figures 1 to 12 As shown, a lubrication system for a stamping device includes an oil tank 1, a frame 7, a plurality of filters 6 and a driving mechanism 8, as shown in FIG. Figure 1 As shown, the oil tank 1 is fixedly installed at the top position of the stamping equipment 2; Figure 2 As shown, an oil return pipe 4 and an oil outlet pipe 5 connected to the oil tank 1 are installed at upper and lower positions on one side of the oil tank 1 respectively; Figure 4 and Figure 7 As shown, the frame 7 is rotatably installed in the oil tank 1, and the oil return pipe 4 extends along the axis of the frame 7 to the inside of the frame 7; the filter element 6 is detachably installed on the frame 7, and the lowermost filter element 6 cooperates with the oil tank 1 to form a filtering area; the driving mechanism 8 is installed on the other side of the oil tank 1 and the output end is connected to the frame 7.

[0034] It is understandable that when filtering, the oil pump 3 extracts the lubricating oil in the oil tank 1 through the oil outlet pipe 5 and delivers it to the mechanism that needs lubrication in the stamping equipment 2 (such as the clutch, brake, crank flywheel bearing, etc.), lubricates and dissipates the heat, and then enters the upper end of the oil tank 1 through the return oil pipe 4, and then filters the impurities in the oil body through the filter area, and then returns to the bottom end of the oil tank 1. After filtering for a period of time, when the filter element 6 is blocked and needs to be replaced, the drive mechanism 8 is started at this time, and the drive mechanism 8 will drive the frame 7 to rotate the set angle, and then the next filter element 6 is rotated to the lowest position, that is, a new filtering area is formed.

[0035] It can be seen that by rotating and replacing the filter element 6, the filter element 6 can be replaced without stopping the machine, thereby avoiding the downtime caused by replacing the filter element 6. In addition, this replacement method is simple and convenient, and effectively improves the working efficiency of the stamping equipment 2.

[0036] Specifically, the present application does not specifically limit the shape of the frame 7 and the number of filters 6. For example, the frame 7 can be a regular polygonal structure, such as a regular hexagon, and the corresponding filter elements 6 can be six, that is, they can be detachably installed at the side positions of the regular hexagon. The frame 7 can also be circular, and the corresponding filter elements 6 are described as two in the specific embodiment of the present application. Of course, the filter elements 6 can also be three, four... The specific number is set by those skilled in the art according to actual conditions. It should be noted that when the frame 7 adopts a circular structure, the corresponding filter element 6 preferably adopts an arc structure.

[0037] As a further description of the above embodiment: the frame 7 is circular, and the filter element 6 is a pair of (upper) filter element 6 and (lower) filter element 6. Initially, the (lower) filter element 6 is located in the filter area to filter the lubricating oil; when the (lower) filter element 6 is blocked, the drive mechanism 8 drives the frame 7 to rotate 180 degrees, and then the original (lower) filter element 6 is rotated to the upper position, and the original (upper) filter element 6 is rotated to the lower position, and the two are swapped to realize the automatic replacement process of the filter element 6. Of course, by analogy, if three filters 6 are used, the frame 7 will rotate 120 degrees, so that the adjacent filter element 6 is rotated to the lowest position.

[0038] Furthermore, in order to ensure that the lubricant returning from the oil return pipe 4 can pass through the filter area evenly, Figure 7 As shown, the oil return pipe 4 is extended along the length direction of the inside of the frame 7, and a plurality of branch pipes 13 are equidistantly arranged outside the oil return pipe 4. It is understandable that the oil return pipe 4 and the branch pipes 13 located in the oil tank 1 are both provided with a plurality of oil outlet holes outside, so that the lubricating oil can fall evenly in the filter area under the action of the branch pipes 13, so that the filter element 6 can be fully utilized, thereby improving the filtering efficiency and filtering effect. At the same time, the provision of the branch pipes 13 can also play a role in slowing down the falling speed of the lubricating oil, avoiding the lubricating oil from directly and massively impacting the filter element 6, thereby extending the service life of the filter element 6.

[0039] In this embodiment, Figure 6 As shown, the installation method of the filter element 6 is: the filter element 6 is plugged and installed on the frame 7. Specifically, a slot 11 is provided on the side of the frame 7, and an insert block 10 is provided at one end of the filter element 6; when installing, the filter element 6 is first inserted into the frame 7 from the slot 11, and when the filter element 6 is inserted into place, the insert block 10 is plugged and matched with the slot 11, thereby completing the installation of the filter element 6; similarly, when disassembling, it is only necessary to pull the filter element 6 out of the slot 11. This installation method is simple and fast, and greatly improves the replacement rate of the filter element 6.

[0040] Of course, the thickness of the slot 11 is preferably greater than the thickness of the filter 6, because in the subsequent extraction process, if the thickness of the slot 11 matches the thickness of the filter 6, the slot 11 acts as a scraper, and the impurities filtered by the filter 6 will be scraped off when the filter 6 is extracted. When extracting at this time, the filter 6 can be pulled out by pressing against the top of the slot 11, so that there is enough space between the side of the filter 6 with impurities and the bottom of the slot 11, so that the impurities can be prevented from being scraped off.

[0041] Furthermore, after the blocked filter 6 is rotated to the upper position, the oil remaining on the filter 6 will fall down under the action of gravity, and the oil adhering to the filter 6 can be drained, thereby preventing the waste of the oil. Of course, impurities on the filter 6 may also fall off, so the filter 6 can be made of magnetic material. As we know, most impurities are iron filings, so the impurities can be prevented from falling into the new filter 6, thereby ensuring the filtering effect of the new filter 6.

[0042] However, the existing lubrication system will have the following problems during use: after the stamping equipment 2 is shut down, the lubricating oil in the oil tank 1 will remain stationary, and due to the effects of gravity and a long period of time, sediment will form at the bottom of the oil tank 1; when the stamping equipment 2 is started next time, the sediment of the lubricating oil will be broken up by the flow force, which will affect the quality of the lubricating oil and even cause damage to the stamping equipment 2 in severe cases.

[0043] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Figure 4 and Fig.11 As shown, a partition component 14 can be arranged inside the oil tank 1 and near the bottom. In order to reduce the setting of the driving mechanism 8, the driving of the partition component 14 and the frame 7 can share a driving mechanism 8; the specific setting method is: the partition component 14 and the frame 7 are both connected to the output end of the driving mechanism 8 in a one-way transmission manner.

[0044] It is understandable that when the driving mechanism 8 performs the first action, the driving mechanism 8 can drive the frame 7 to rotate, thereby realizing the replacement of the filter element 6. Of course, at this time, the partition assembly 14 is in a stationary state. When the driving mechanism 8 performs the second action, the driving mechanism 8 can drive the partition assembly 14 to expand or contract. Of course, at this time, the frame 7 is in a stationary state. When the partition assembly 14 is expanded, Fig.10As shown, the partition assembly 14 can separate the bottom and the middle and upper parts of the oil tank 1, that is, the oil tank 1 can be divided into an upper oiling area 101 and a lower sedimentation area 102. Of course, the oil outlet pipe 5 must be located in the upper oiling area 101, so that the sediment can be separated from the clean lubricating oil, thereby improving the service life of the lubricating oil. When the partition assembly 14 is retracted, the partition assembly 14 will be folded and attached to the inner wall of the oil tank 1, so as not to interfere with the sedimentation of the lubricating oil after the next shutdown.

[0045] As a further description of the above embodiment: Figure 4 As shown, the driving mechanism 8 includes a driving device 1 801, a driving device 2 802 and a motor 803. The driving device 1 801 is installed on the oil tank 1 and its output end is connected to the frame 7. The input end of the driving device 1 801 and the output shaft of the motor 803 are connected in a one-way transmission through a transmission component 18. The driving device 2 802 is installed on the oil tank 1 and its output end is connected to the partition component 14. The input end of the driving device 2 802 and the output shaft of the motor 803 are connected in a one-way transmission through a transmission component 2 19.

[0046] It can be understood that when the first action is performed (set as the forward rotation of the motor 803), the motor 803 drives the driving device 1 801 to move through the transmission component 1 18 to achieve the rotation of the frame 7, while the driving device 2 802 remains stationary. When the second action is performed (set as the reverse rotation of the motor 803), the motor 803 drives the driving device 2 802 to move through the transmission component 2 19 to achieve the expansion or contraction of the partition component 14, while the driving device 1 801 remains stationary.

[0047] The present application does not specifically limit the structures of the two transmission components, and a specific embodiment is provided below for reference:

[0048] like Fig. 9 As shown, the transmission assembly 18 includes a pulley 1 1801, a pulley 2 1802 and a transmission belt 1 1803. The pulley 1 1801 is installed at the input end of the driving device 1 801, the pulley 2 1802 is installed at the output shaft of the motor 803 through a one-way bearing 20, and the transmission belt 1 1803 is sleeved on the outside of the pulley 1 1801 and the pulley 2 1802. The transmission assembly 2 19 includes a pulley 3 1901, a pulley 4 1902 and a transmission belt 2 1903. The pulley 3 1901 is installed at the output shaft of the motor 803 through a one-way bearing 20, the pulley 4 1902 is installed at the input end of the driving device 2 802, and the transmission belt 2 1903 is sleeved on the outside of the pulley 3 1901 and the pulley 4 1902.

[0049] It is understandable that when the motor 803 rotates forward, the one-way bearing 20 on the second pulley 1802 is in a bite state, while the one-way bearing 20 on the third pulley 1901 is in a free state, so the cooperation of the second pulley 1802, the first pulley 1801 and the transmission belt 1 1803 can drive the driving device 1 801 to operate. Similarly, when the motor 803 rotates reversely, the one-way bearing 20 on the third pulley 1901 is in a bite state, while the one-way bearing 20 on the second pulley 1802 is in a free state, so the cooperation of the third pulley 1901, the fourth pulley 1902 and the transmission belt 2 1903 can drive the driving device 2 802 to operate. It should be noted that the two transmission components can also adopt chain transmission and gear transmission.

[0050] Specifically, Figure 8 As shown, the driving device 801 includes a worm wheel 8011 and a worm 8012 . The worm wheel 8011 is installed outside the rotating rod 12 of the frame 7 . The worm 8012 is installed horizontally on the oil tank 1 . The pulley 1801 is installed at the end of the worm 8012 .

[0051] It is understood that when performing the first action, the motor 803 rotates forward and drives the worm 8012 to rotate through the transmission component 18, and the frame 7 is driven to rotate under the meshing transmission of the worm 8012 and the worm wheel 8011. It should also be known that the worm 8012 and the worm wheel 8011 have self-locking properties, so when the worm 8012 stops rotating, the frame 7 can also maintain the rotated state under this self-locking force.

[0052] like Figure 8 As shown, the partition assembly 14 includes a pair of partition plates 1401, which are rotatably mounted on the inner walls of the oil tank 1 on both sides through a rotating shaft. The second driving device 802 includes a driving rod 8021, a pair of moving rods 8022 and a pair of connecting rods 8023, wherein the driving rod 8021 is horizontally rotatably mounted on the oil tank 1, and the driving rod 8021 and the worm 8012 are parallelly distributed, and both ends of the outside of the driving rod 8021 are provided with reciprocating screw rod segments 15, and the moving rod 8022 is horizontally slidably arranged on the oil tank 1 and cooperates with the reciprocating screw rod segment 15, one end of the connecting rod 8023 is fixedly connected to the rotating shaft, and the other end of the connecting rod 8023 is provided with a pin 16, and the outside of the driving rod 8021 is provided with a waist-shaped groove 17, and the pin 16 is movably matched with the waist-shaped groove 17, and the pulley 4 1902 is sleeved and installed on the outside of the driving rod 8021.

[0053] It is understandable that if Fig.10As shown in (b) of FIG. 1 , it is assumed that in the initial state, the two partition plates 1401 are located in the same straight line and are opposed to each other, and then the interior of the oil tank 1 is divided into an upper oiling area 101 and a lower sedimentation area 102 under the action of the partition plates 1401, and at this time, the two moving rods 8022 are in a close state, as shown in FIG. Fig.10 When the second action is performed, the motor 803 reverses and drives the driving rod 8021 to rotate through the transmission component 19. Under the action of the reciprocating wire rod section 15, the two moving rods 8022 will move synchronously and move away from each other, as shown in FIG. Fig.11 As shown in (c) in the figure, the moving rod 8022 acts on the connecting rod 8023, and the pin 16 at the other end of the connecting rod 8023 moves along the waist-shaped groove 17, and then one end of the connecting rod 8023 drives the rotating shaft to rotate, so that the two partition plates 1401 rotate away from each other, and until the two partition plates 1401 are against the inner walls of the two sides of the oil tank 1, so that the upper oil area 101 and the lower sedimentation area 102 are connected, as shown in FIG. Fig.11 As shown in (d) in the figure, this facilitates the sedimentation of the lubricating oil.

[0054] It should be known that if Fig.11 As shown, after the two moving rods 8022 move relatively far away from each other to the limit position, the partition plate 1401 shrinks and is attached to the inner wall of the oil tank 1 under its action. When the motor 803 continues to reverse, the two moving rods 8022 move relatively close to each other under the action of the reciprocating screw rod section 15. When the two moving rods 8022 move relatively close to the minimum distance, the partition plate 1401 returns to its initial state under its action. Fig.10 Moreover, the reciprocating screw segment 15 is similar to the "screw slider" in nature, and the driving rod 8021 and the two moving rods 8022 are also self-locking, that is, after the driving rod 8021 stops rotating, the two moving rods 8022 can remain stationary under the action of the thread, so that the two partition plates 1401 remain in the state after rotation adjustment.

[0055] Based on the above embodiment, we know that the locking of the frame 7 and the partition plate 1401 after adjustment depends on the worm 8012 and the driving rod 8021 stopping their rotation. Of course, in theory, after the motor 803 stops rotating, the worm 8012 and the driving rod 8021 will also stop rotating. However, the punching equipment 2 will generate impact force during the punching operation, and the oil pump 3 will also generate vibration during operation. Under the action of these forces, the worm 8012 and the driving rod 8021 may also rotate slightly, thereby affecting the accuracy of the frame 7 and the partition plate 1401 after adjustment.

[0056] Therefore, in order to solve the above technical problems, in one embodiment of the present application, Fig.12As shown, the worm 8012 and the drive rod 8021 are both matched with the oil tank 1 through the clutch structure 21. It is understandable that when the motor 803 stops running, the worm 8012 and the drive rod 8021 can be limited and kept stationary under the action of the clutch structure 21.

[0057] Specifically, Fig.12 As shown, we take the worm 8012 as an example for explanation (the drive rod 8021 and the worm 8012 are arranged in the same manner, so they are not shown). The clutch structure 21 includes a clutch block 2101 (of a spherical structure) and a plurality of clutch grooves 2102 (of a hemispherical structure). The clutch block 2101 is elastically slidably installed on the side of the oil tank 1 through a spring, and the clutch groove 2102 is arranged on the outside of the drive rod 8021 and the worm 8012.

[0058] It should be known that, for the worm 8012, the number of clutch slots 2102 and the number of filter elements 6 are the same. For the present application, two filter elements 6 are used, and the number of clutch slots 2102 is also two. When one of the filter elements 6 is located at the lowest position, the clutch block 2101 cooperates with one of the clutch slots 2102 under the action of elastic force; and when the other filter element 6 is adjusted and rotated to the lowest position, the clutch block 2101 will just cooperate with the other clutch slot 2102 under the action of elastic force, thereby achieving stable positioning of the adjusted frame 7. Of course, during adjustment, the clutch block 2101 will separate from the clutch slot 2102 under the forced force of the worm 8012, thereby not interfering with the rotation of the worm 8012. As for the driving rod 8021, the number of its clutch grooves 2102 is two, that is, it is sufficient to limit the two partition plates 1401 in two states of being fully expanded and fully retracted.

[0059] The working principle of the present invention is:

[0060] When the filter element 6 (i.e., the filter screen) of the stamping device 2 needs to be replaced, the motor 803 is started to rotate forward, and the one-way bearing 20 on the pulley 1802 is in a bite state, and then the worm 8012 rotates under the cooperation of the pulley 1801 and the transmission belt 1803, and the worm 8012 acts on the worm wheel 8011 to rotate, and then drives the frame 7 to rotate through the rotating rod 12, and the top filter element 6 is rotated to the filtering area below for use. When replacing the blocked filter element 6, if Figure 1 As shown, the staff can climb to the top via the ladder on the rear side of the stamping equipment 2, then open the protective cover on the rear side of the oil tank 1, extract the filtered filter element 6 and replace it with a new filter element 6, which is simple and convenient.

[0061] When the stamping equipment 2 is stopped, the start motor 803 is reversed, and the one-way bearing 20 on the pulley three 1901 is in a biting state, and then the driving rod 8021 is rotated under the cooperation of the pulley three 1901, the pulley four 1902 and the transmission belt two 1903, and the two partition plates 1401 are relatively rotated away from each other under the action of the reciprocating wire rod segment 15, until the two partition plates 1401 are against the inner walls of the oil tank 1 on both sides, so that the upper oil area 101 and the lower sedimentation area 102 are connected, as shown in FIG. Fig.11 As shown in (d) in the figure, the impurities in the lubricating oil are precipitated. Before the next start of the stamping equipment 2, the motor 803 is started again to reverse, so that the two partition plates 1401 are reversed to the initial isolation state, so that the isolated precipitation is separated from the lubricating oil, thereby improving the quality of the lubricating oil. When there are a lot of precipitation, such as Figure 4 As shown, the drain pipe 9 near the bottom of the oil tank 1 can be opened to discharge the impurities and sediments, and a proper amount of lubricating oil can be added to increase the service life of the lubricating oil.
