Description

Technical Field

[0001] This utility model relates to the technical field of button battery manufacturing equipment, specifically to a lubrication mechanism and a punch press. Background Technology

[0002] In the production of button batteries, the metal casing is typically formed by punching continuous metal strips using a high-speed punch press. During punching, intense friction occurs between the punch and the metal strip. Insufficient lubrication can not only accelerate punch wear and reduce die life, but also lead to increased punching burrs, decreased dimensional accuracy, and even strip feeding deviation due to uneven friction, affecting production continuity and product qualification rate.

[0003] To lubricate the punching process, existing technologies typically employ the method of applying oil to the strip before punching. For example, Chinese utility model patent CN 206613940 U discloses a punching lubrication device for button battery raw material strips, including a dripping mechanism and a lubrication positioning mechanism; the oil outlet of the dripping mechanism and the lubrication positioning mechanism are arranged sequentially in the feeding direction at the raw material strip in front of the punching head.

[0004] The existing technology has the following problems: the device can only lubricate the upper surface of the raw material strip. During the punching process, the lower surface of the strip also comes into contact and rubs with the lower die or pad. Single-sided lubrication cannot effectively reduce the friction coefficient of the lower surface, resulting in uneven lubrication effect. The lower die still wears out quickly, and the asymmetrical force on the upper and lower surfaces of the strip during punching may affect the forming quality. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a lubrication mechanism to solve the technical problem that the existing technology fails to achieve uniform double-sided lubrication of the raw material strip.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a lubrication mechanism, comprising: Frame; The first guiding mechanism is mounted on the frame and has a guide end that guides the strip material to flip over to the lower surface with the surface tilted upward. The second guiding mechanism, mounted on the frame and arranged downstream of the first guiding mechanism in the conveying direction, has a guiding end that guides the strip material to flip over to an upward-facing guide end; and The lubrication assembly is installed on the frame in a one-to-one correspondence with the first guide mechanism and the second guide mechanism, and each has a lubrication end, which is used to lubricate the upper and lower surfaces of the strip material respectively.

[0007] In some embodiments, the system further includes an oil supply assembly, comprising an oil supply tank and two branch oil lines, wherein the two branch oil lines are respectively connected to two lubrication ends of the lubrication assembly and supply oil to the two lubrication ends respectively, and the branch oil lines are provided with flow regulating valves.

[0008] In some embodiments, the first guiding mechanism includes a first roller rotatably connected to the frame; the second guiding mechanism includes a second roller rotatably connected to the frame and arranged below the first roller for conveying the strip material from top to bottom in an S-shape.

[0009] In some embodiments, the lubrication assembly includes a connecting pipe, a distribution plate, and an oil reservoir. The distribution plate has at least one oil discharge hole along the radial direction of the strip material. The oil reservoir is detachably connected to the distribution plate. The connecting pipe is connected to the top of the distribution plate. The branch oil passage is plugged into the connecting pipe.

[0010] In some embodiments, the uniform distribution plate is provided with insert plates on both sides, and the oil storage pad is sleeved between the outer sides of the two insert plates and abuts against the bottom of the uniform distribution plate.

[0011] In some embodiments, the lubrication assembly further includes a linear adjustment mechanism having a telescopic end that is linearly movable, the lubrication assembly being connected to the telescopic end of the linear adjustment mechanism for adjusting position.

[0012] In some embodiments, the linear adjustment mechanism includes a slide rod, a sleeve, and a locking bolt. The locking bolt is threaded onto the sleeve and passes through the sleeve to abut against the slide rod. The sleeve is connected to the lubrication assembly, and the slide rod is connected to the frame.

[0014] In some embodiments, the frame is provided with a guide frame, which is arranged at the end of the conveying direction of the strip material for the strip material to pass through after passing the first guide mechanism and the second guide mechanism.

[0015] Secondly, this utility model also provides a punch press, including a lubrication mechanism as described in any of the above.

[0016] Compared with the prior art, the lubrication mechanism provided by this utility model uses a frame as a support structure.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem of failing to achieve uniform double-sided lubrication of raw material strips, this invention provides a lubrication mechanism. This mechanism utilizes a frame as a support structure. A first guide mechanism flips the strip so its lower surface faces upwards, while a second guide mechanism below flips the strip so its upper surface faces upwards. The lubrication ends of the two lubrication components correspond to these two guide mechanisms, lubricating both sides of the strip to achieve double-sided lubrication. The structure is simple and suitable for low-cost upgrades to existing production lines.

[0021] It should be noted that the lubrication mechanism described in this utility model is used for, but not limited to, lubrication before feeding of strip materials into a punch press. For ease of explanation, this utility model only uses the application of the lubrication mechanism to lubricate strip materials before feeding into a punch press as an example. The principle of the lubrication mechanism applied to other types of equipment is essentially the same as that applied to lubrication before feeding strip materials into a punch press, and will not be elaborated here.

[0022] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a lubrication mechanism, which includes a frame 1, a first guide mechanism 2, a second guide mechanism 3, and a lubrication assembly 4. The first guide mechanism 2 is mounted on the frame 1 and has a guide end that guides the strip material to flip so that its lower surface is inclined upward, facilitating lubrication of the lower surface of the strip material. The second guide mechanism 3 is mounted on the frame 1 and arranged downstream of the first guide mechanism 2 in the conveying direction, and has a guide end that guides the strip material to flip so that its upper surface is upward, facilitating lubrication of the lower surface of the strip material. The material returns to its upward-facing state for lubrication. The lubrication assembly 4 is installed on the frame 1 in a one-to-one correspondence with the first guide mechanism 2 and the second guide mechanism 3, and each has a lubrication end for contact lubrication of the upper and lower surfaces of the strip material. The lubrication ends face downwards, which facilitates the replenishment of lubricating oil by gravity dripping without requiring major structural adjustments. It can be adapted to the simplest gravity downward oil supply method for supplying lubricating oil. Contact lubrication can be performed when the surface to be lubricated is facing upwards.

[0023] In this embodiment, please refer to Figure 1 and Figure 2 In order to supply oil to the lubrication assembly 4, an oil supply assembly 5 is also included, which includes an oil supply tank 51 and two branch oil lines 52. The two branch oil lines 52 are respectively connected to the two lubrication ends of the lubrication assembly 4 and supply oil to the two lubrication ends respectively. The branch oil lines 52 are equipped with flow regulating valves 53. The oil supply tank 51 is mounted on the frame 1 by a bracket and is located above the two lubrication ends. The oil pipes of the branch oil lines 52 extend vertically downwards and deliver lubricating oil to the lubrication ends. The flow rate of the lubricating oil is regulated and controlled by the flow regulating valves 53.

[0024] Understandably, if the installation height of the oil supply tank 51 is limited by the installation location and cannot meet the needs of the two lubrication ends, an active pumping oil supply method can be adopted. In this case, an oil pump can be installed between the branch oil line 52 and the oil supply tank 51 to pump oil. This will not be elaborated on further here.

[0025] Further, please refer to Figure 1 and Figure 2 To redirect the strip material, the first guide mechanism 2 includes a first roller 21, which is rotatably connected to the frame 1. The strip material can be conveyed downwards around the first roller 21, with its lower surface facing upwards and to the side. Figure 2As shown; the second guiding mechanism 3 includes a second roller 31, which is rotatably connected to the frame 1 and arranged below the side of the first roller 21. It is used to convey the strip material from top to bottom in an S-shape. After the lower surface faces the upper side, it passes under the second roller 31 and can turn the upper surface upward again for subsequent conveying, thereby satisfying the purpose of sequentially changing the direction of the lower and upper surfaces.

[0026] The lubrication end of the first lubrication component 4 corresponds to the first roller 21 and is between the first lubrication component 4 and the second roller 31, through which the strip material passes, so that the first lubrication component 4 abuts against the lower surface of the strip material for oiling; the lubrication end of the second lubrication component 4 corresponds to the second roller 31 and is located below the right side of the second roller 31, so that the strip material that passes around the second roller 31 passes over the lubrication end of the second lubrication component 4 and extends downward, so that it fully abuts against the lubrication end for oiling the upper surface.

[0027] In one embodiment, please refer to Figure 2 and Figure 3 To achieve uniform oil distribution, the lubrication assembly 4 includes a connecting pipe 41, a distribution plate 42, and an oil storage pad 43. The distribution plate 42 has at least one oil discharge hole 44 along the radial direction of the strip material, thereby evenly distributing oil in the width direction of the strip material. The oil discharge hole 44 is located in the middle area of ​​the contact area with the strip material, where the contact is most stable and can meet the oiling requirements. The oil storage pad 43 is detachably connected to the distribution plate 42. The connecting pipe 41 is connected to the top of the distribution plate 42. The branch oil passage 52 is inserted into the connecting pipe 41. The oil enters the connecting pipe 41, then accumulates in the connecting pipe 41, and is evenly distributed through the oil discharge hole 44 on the distribution plate 42 and immersed in the oil storage pad 43. When the strip material slides relative to the oil storage pad 43, it is coated with oil, thus achieving the purpose of oiling.

[0028] Furthermore, to facilitate the installation and removal of the oil storage pad 43, insert plates 45 are provided on both sides of the uniform distribution plate 42. The oil storage pad 43 is sleeved between the outer sides of the two insert plates 45 and abuts against the bottom of the uniform distribution plate 42. The oil storage pad 43 can be made of sponge, with grooves on the sponge that match the insert plates 45. Sleeving it onto the insert plates 45 achieves the installation effect. Conversely, by sleeved and disassembled, the oil storage pad 43 can be replaced.

[0029] For further details, please refer to Figure 2 and Figure 3 In order to adjust the gap between the oil storage pad 43 and the strip material, and to adapt to the oiling of strip materials of different thicknesses, the lubrication component 4 also includes a linear adjustment mechanism 46. The linear adjustment mechanism 46 has a telescopic end that can move linearly. The lubrication component 4 is connected to the telescopic end of the linear adjustment mechanism 46 for adjusting the position, thereby achieving the purpose of adapting to strip materials of different thicknesses.

[0030] Furthermore, the linear adjustment mechanism 46 includes a slide rod 461, a sleeve 462, and a locking bolt 463. The locking bolt 463 is threaded onto the sleeve 462 and passes through the sleeve 462 to abut against the slide rod 461. The sleeve 462 is connected to the lubrication assembly 4, and the slide rod 461 is connected to the frame 1. By rotating the locking bolt 463, the sleeve 462 and the slide rod 461 slide relative to each other to adjust the position and control the distance between the oil accumulator 43 and the strip material, thereby adapting to strip materials of different thicknesses and controlling the abutment pressure between the oil accumulator 43 and the strip material. Finally, the locking bolt 463 is used to lock the sleeve 462 onto the slide rod 461.

[0031] Furthermore, to prevent the sleeve 462 from detaching from the slide rod 461, a limiting flange 464 is provided at the bottom of the slide rod 461 to prevent the sleeve 462 from detaching from the slide rod 461.

[0032] In one embodiment, please refer to Figure 2 and Figure 3 In order to guide the strip material to extend upward when the second lubrication component 4 is located to the lower right of the second roller 31, and then feed it with the punch press so that the strip material fully contacts the oil storage pad 43 on the second lubrication component 4, the frame 1 is provided with a guide frame 101. The guide frame is arranged at the end of the conveying direction of the strip material, and is used for the strip material to pass through after passing the first guide mechanism 2 and the second guide mechanism 3.

[0033] This utility model also provides a punch press, including a lubrication mechanism as described in any embodiment, which is installed at the feed inlet of the punch press and docks with the feed inlet. The strip material is sequentially passed around the first roller 21, the first lubrication component 4, the second roller 31, the second lubrication component 4 and the guide frame 101, and then enters the feed inlet of the punch press for stamping.

[0034] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail as follows: The strip material first passes down from the upper side of the first roller 21, then passes to the lower left, and then passes between the oil storage pad 43 of the left lubrication component 4 and the second roller 31 for lubrication of the lower surface. Then it passes from the lower left of the second roller 31 to the lower right of the second roller 31, and then from the bottom of the oil storage pad 43 attached to the right lubrication component 4 for lubrication of the upper surface. Then it extends to the upper right, passes through the guide frame 101, and then enters the punch press for stamping. The flow regulating valve 53 is opened to deliver the lubricating oil in the oil supply tank 51 to the left and right lubrication components 4 through the branch oil passage 52. After passing through the connecting pipe 41, it is evenly distributed from the oil outlet hole 44 on the distribution plate 42 and then immersed in the oil storage pad 43 for supplying and replenishing the lubricating oil.

[0035] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
