Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to an oiling device suitable for multi-station stamping production lines. Background Technology

[0002] A multi-station stamping production line is an advanced press equipment that integrates multiple presses and a destacking and feeding system. A single multi-station press can achieve the functions of an automated press production line. This type of production line typically consists of a head unit, a feeding mechanism, a press, and a tail unit, with a maximum cycle time of over 25 cycles per minute, meeting the demands of high-speed automated production.

[0003] During the stamping process, the friction between the sheet metal and the die generates a large amount of heat, leading to surface damage to the material and wear on the die, which in turn affects the quality of the sheet metal and the life of the die. To solve this problem, the sheet metal needs to be oiled before stamping to reduce friction between the sheet metal and the die.

[0004] However, there is currently no dedicated oiling device for multi-station stamping production lines. To solve the oiling problem, the traditional approach is to install oil spraying devices on both the top and bottom sides of the belt conveyor, thus applying oil during belt transport. This open structure, however, leads to oil mist overflow and environmental pollution. Utility Model Content

[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0038] For ease of description, the coordinate system is defined as follows: Figure 2 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0039] Example 1

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, an oiling device suitable for a multi-station stamping production line includes a main frame, which comprises a frame and a protective cover mounted on the frame, forming a closed mounting cavity. A conveying unit for conveying sheet metal is disposed within the mounting cavity. The protective cover has an inlet 231 on the feeding side of the conveying unit and an outlet on the discharging side of the conveying unit. Oil spraying units 4 are respectively disposed on the upper and lower sides of the conveying unit within the mounting cavity. The oil spraying units 4 are prior art, and their structure will not be described in detail here.

[0041] During operation, the sheet metal enters through the feed inlet 231 and exits through the discharge outlet under the conveying action of the conveying component 32. During this conveying process, the oil spraying units 4 located on the upper and lower sides of the conveying unit operate simultaneously, spraying oil onto the upper and lower sides of the sheet metal. Since the oil spraying units 4 are located within the mounting cavity, and the mounting cavity is only connected to the outside through the narrow feed inlet 231 and discharge outlet, oil mist overflow can be effectively prevented, avoiding environmental pollution.

[0042] As one specific implementation method, such as Figure 1 and Figure 2 As shown, the frame in this embodiment includes a horizontal frame 11, and vertical frames 12 for supporting the horizontal frame 11 are respectively provided at both ends of the horizontal frame 11. The horizontal frame 11 and the vertical frames 12 together form a gantry structure. The oil spraying unit 4 located on the upper side of the conveying unit is detachably fixed to the horizontal frame 11, and the two ends of the oil spraying unit 4 located on the lower side of the conveying unit are respectively detachably fixed to the vertical frames 12.

[0043] As one specific implementation method, such as Figure 1 and Figure 2 As shown, in this embodiment, the entire frame is located inside the protective cover. The protective cover includes a top plate 21, a bottom plate 22, a front baffle 23, a rear baffle, and two side plates 24. The top plate 21 is located at the top of the frame and is fixedly connected to the top surfaces of the uprights 12 and the crossbars 11; the bottom plate 22 is located at the bottom of the frame and is fixedly connected to the bottom surface of the uprights 12; the two side plates 24 are located on the left and right sides of the frame, respectively, and are fixedly connected to the uprights 12; the front baffle 23 is fixedly disposed on the front side of the frame, and a feed inlet 231 is provided on the front baffle 23; the rear baffle is fixedly disposed on the rear side of the frame, and a discharge outlet is provided on the rear baffle.

[0044] like Figure 3 and Figure 4 As shown, the conveying assembly includes a conveyor frame 31, and both ends of the conveyor frame 31 are detachably fixed to the upright frame 12. A plurality of conveying components 32 are evenly distributed along the transverse direction on the upper side of the conveyor frame 31.

[0045] In one specific implementation, the conveyor frame 31 described in this embodiment is provided with 13 sets of conveying components 32 evenly distributed along the transverse direction.

[0046] like Figure 5 and Figure 9As shown, the conveying component 32 includes a mounting frame, which is detachably and fixedly connected to the conveying frame 31. A conveying assembly is mounted on the mounting frame, comprising a driving pulley 3221, a driven pulley 3222, and a conveyor belt 3223 connecting the driving pulley 3221 and the driven pulley 3222. The driving pulley 3221 and the driven pulley 3222 are located at opposite ends of the mounting frame, and the driving pulley 3221 is connected to a driving component. Figure 2 In the coordinate system shown, the driving pulley 3221 is located at the front end of the mounting frame, and the driven pulley 3222 is located at the rear end of the mounting frame.

[0047] The mounting frame includes a horizontal plate and a vertical plate extending upwards perpendicular to the horizontal plate. The conveying assembly is located on one side of the vertical plate, and a support plate extending away from the conveying assembly is provided at the top of the vertical plate, with the upper side of the support plate flush with the conveying plane of the conveyor belt 3223. Figure 2 In the coordinate system shown, the conveying component is located on the right side of the vertical plate, the pallet is located on the left side of the vertical plate, and the right end of the pallet is fixedly connected to the upper end face of the vertical plate.

[0048] like Figure 3 , Figure 5 , Figure 9 and Figure 10 As shown, the driving component includes a drive shaft 331 and a first drive motor 332 for driving the drive shaft 331 to rotate. The drive shaft 331 extends laterally, and both ends of the drive shaft 331 are rotatably connected to the conveyor frame 31 or the frame via bearing assemblies. The drive pulleys 3221 of each of the conveying components 32 are connected to the drive shaft 331 via transmission mechanisms.

[0049] In one specific implementation, the two ends of the drive shaft 331 are rotatably connected to the conveyor frame 31 via vertical bearings 333. The first drive motor 332 is located outside the protective cover, and one end of the drive shaft 331 passes through the protective cover and is directly connected to the power output shaft of the first drive motor 332. Placing the first drive motor 332 outside the protective cover reduces contamination of the first drive motor 332, thereby extending its service life.

[0050] In one specific embodiment, the transmission mechanism described in this embodiment adopts gear transmission. The transmission mechanism includes a driving gear 3341 disposed on the drive shaft 331, and a driven gear 3342 that meshes with the driving gear 3341 is disposed on the driving pulley 3221.

[0051] As one specific implementation method, such as Figure 6 As shown, in this embodiment, a rotating shaft 324 is fixedly mounted on the mounting bracket, and the driving pulley 3221 is rotatably connected to the rotating shaft 324 via a bearing assembly. A driven gear 3342 is coaxially arranged with the driving pulley 3221 on one side, and the driven gear 3342 is fixedly connected to the driving pulley 3221 by a plurality of first bolts 34. For example, the driven gear 3342 is located on the side of the driving pulley 3221 facing the mounting bracket, and the plurality of first bolts 34 are evenly arranged around the rotating shaft 324.

[0052] Furthermore, such as Figure 9 and Figure 10 As shown, the drive shaft 331 is located between the driving pulley 3221 and the driven pulley 3222, and the vertical plate of the mounting bracket is provided with a clearance opening 3211 for avoiding the drive shaft 331. This reduces the size of the conveying component 32, thereby facilitating installation.

[0053] Furthermore, such as Figure 5 As shown, the drive shaft 331 is equipped with pressure rollers 335 that correspond one-to-one with the conveying components 32. The pressure rollers 335 are used to press the conveyor belt 3223 of the corresponding conveying component 32 from the outside. By setting the pressure rollers 335, the envelope angle of the conveyor belt 3223 on the drive pulley 3221 can be increased, and the tension of the conveyor belt 3223 can be increased.

[0054] In one specific embodiment, in this example, the drive gear 3341 and the pressure roller 335, corresponding to the same conveying component 32, are both connected to the drive shaft 331 via bushings 336. The bushings 336 are fixedly mounted on the drive shaft 331 and can rotate synchronously with it. The drive gear 3341 is detachably fixedly connected to the bushings 336, and the pressure roller 335 is rotatably connected to the bushings 336 via bearing assemblies.

[0055] Furthermore, such as Figure 5 and Figure 9 As shown, the mounting frame has transition components 325 for supporting the plate material on both the infeed and discharge sides, and the transition components 325 are located on the side of the vertical plate opposite to the conveying assembly. The transition component 325 includes a bracket and a support roller 3253 disposed at the top of the bracket.

[0056] In one specific embodiment, the bracket in this example includes a first support plate 3251 extending in the front-to-back direction, and the first support plate 3251 is fixedly connected to the vertical plate by a second bolt 3254. The locking hole on the first support plate 3251 for accommodating the second bolt 3254 is an elongated hole with a length along the front-to-back direction. A second support plate 3252 extending upward is fixedly disposed at the outer end of the first support plate 3251 (with the side opposite to the two transition components 325 as the inner side), and the support roller 3253 is disposed at the top end of the second support plate 3252.

[0057] Furthermore, such as Figure 9 As shown, a scraper 326 is provided on the mounting frame below the conveyor belt 3223, and the scraper 326 is used to scrape off dirt on the conveyor belt 3223.

[0058] Furthermore, while oil spraying can effectively solve the problem of frictional heat generation during the stamping process, the presence of oil can also cause difficulties for the conveyor belt 3223, easily leading to slippage. To solve this problem, such as... Figure 5 , Figure 7 and Figure 8 As shown, an adsorption mechanism 327 for adsorbing sheet material is provided on the mounting frame below the horizontal conveying section at the upper end of the conveyor belt 3223. The adsorption mechanism 327 includes a mounting block 3271. A support plate 3212 for supporting the mounting block 3271 is provided on the vertical plate of the mounting frame below the mounting block 3271. One end of the support plate 3212 is fixedly connected to the vertical plate by welding, and the other end of the support plate 3212 is suspended. The mounting block 3271 is detachably fixedly connected to the support plate 3212. A mounting groove is provided on the upper side of the mounting block 3271, and a first magnet 3272 for adsorbing the sheet material is provided in the mounting groove. A cover plate 3273 is provided on the mounting block 3271 above the first magnet 3272, and the cover plate 3273 is detachably fixedly connected to the mounting block 3271. For example, the mounting block 3271 is made of nylon material.

[0059] Furthermore, such as Figure 5 As shown, the drive pulley 3221 has a plurality of mounting holes evenly distributed around the rotating shaft 324, and a second magnet 3224 is disposed in each mounting hole. For example, the number of second magnets 3224 is the same as the number of first bolts 34, and the second magnets 3224 are spaced apart from the first bolts 34. The second magnets 3224 are fixedly disposed in the mounting holes by an interference fit.

[0060] In one specific embodiment, the conveyor frame 31 in this embodiment includes two connecting plates 311, and two transverse beams 312 extending laterally are arranged between the two connecting plates 311. The left and right ends of the transverse beams 312 are fixedly connected to the connecting plates 311 by welding, and the connecting plates 311 are fixedly connected to the upright frame 12 by bolt assemblies. The oil spray nozzle 41 of the oil spraying assembly 4 located on the lower side of the conveyor assembly is located between the two transverse beams 312, and sprays oil onto the lower side of the sheet material through the gap between the two transverse beams 312.

[0061] Furthermore, to provide more clearance for the lower spraying unit 4, so that the oil can be evenly sprayed onto the lower side of the sheet metal. For example... Figure 5 , Figure 9 and Figure 10 As shown, the mounting bracket includes two sub-mounting brackets 321. Each sub-mounting bracket 321 includes a horizontal plate and a vertical plate extending upward perpendicular to the horizontal plate, and the vertical plates of the two sub-mounting brackets 321 are aligned. One of the sub-mounting brackets 321 is fixedly mounted to the front crossbeam 312 by a third bolt (not shown in the figure), and the other sub-mounting bracket 321 is fixedly mounted to the rear crossbeam 312 by a third bolt (not shown in the figure). The driving pulley 3221 is mounted on the front sub-mounting bracket 321, and the driven pulley 3222 is mounted on the rear sub-mounting bracket 321.

[0062] Accordingly, the pallet is divided into two parts, including two sub-pallets 323. One sub-pallet 323 is disposed on the vertical plate of one sub-mounting bracket 321, and the other sub-pallet 323 is disposed on the vertical plate of the other sub-mounting bracket 321. Two transition components 325 are respectively disposed on the two sub-mounting brackets 321, and the transition components 325 are located on the outer side of the sub-mounting bracket 321 (with the opposite side of the two sub-mounting brackets 321 as the inner side). The clearance opening 3211 is disposed on the vertical plate of the sub-mounting bracket 321 on which the drive pulley 3221 is mounted. The vertical plates of the two sub-mounting brackets 321 are respectively provided with support plates 3212 for supporting the mounting block 3271. The scraper 326 is detachably fixed to the vertical plate of the sub-mounting bracket 321 on which the driven pulley 3222 is mounted.

[0063] Furthermore, such as Figure 9As shown, the outer end of the horizontal plate of the sub-mounting bracket 321 on which the driven pulley 3222 is mounted (with the opposite side of the two sub-mounting brackets 321 as the inner side) is provided with a downwardly extending clamping plate 328. The clamping plate 328 is provided with a clamping bolt 3281 for clamping the conveyor frame 31. The locking hole on the horizontal plate of the sub-mounting bracket 321 on which the driven pulley 3222 is mounted is an elongated hole with its length along the front-back direction for accommodating the fourth bolt.

[0064] Furthermore, the bottom of the main frame is provided with support legs 5 at the left and right ends of the main frame, and the bottom of the protective cover is provided with an oil recovery port 221 between the two support legs 5. The oil recovery port 221 can be used to recover the oil that drips onto the bottom of the protective cover, so as to recycle and reuse it.

[0065] Furthermore, such as Figure 1 As shown, the top of the main frame is provided with an oil mist collector 6 that communicates with the mounting cavity. The oil mist collector 6 is used to collect oil mist in the mounting cavity.

[0066] Example 2

[0067] The second magnet 3224 inside the drive pulley 3221 is removed. The conveyor belt 3223 has magnets embedded inside, which can attract the sheet material and transport it forward without slipping or deviating, ensuring that the sheet material's stepping accuracy meets the subsequent tapping accuracy requirements. The conveyor belt 3223 with embedded magnets is existing technology and can be obtained by purchasing it externally. The internal structure of the conveyor belt 3223 will not be described in detail here.

[0068] The rest of the structure is the same as in Example 1.

[0069] Example 3

[0070] The transmission mechanism and pressure roller 335 are removed. The rotating shaft 324 is rotatably connected to the mounting bracket via a bearing assembly, and the drive pulley 3221 can rotate synchronously with the rotating shaft 324. The rotating shaft 324 is provided with a through hole extending axially through the rotating shaft 324, the through hole being used to accommodate the drive shaft 331, and the rotating shaft 324 can rotate synchronously with the drive shaft 331.

[0071] In one specific implementation, the drive pulley 3221 in this embodiment is connected to the rotating shaft 324 via a key connection. The drive shaft 331 is also connected to the rotating shaft 324 via a key connection.

[0072] The rest of the structure is the same as in Example 1.

[0073] Other embodiments obtained by those skilled in the art based on the embodiments provided in this application by combining, splitting, or reorganizing the embodiments of this application do not exceed the protection scope of this application.

[0074] The above detailed embodiments have provided a detailed explanation of the purpose, technical solutions, and beneficial effects of the embodiments of this application. The above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. That is, any modifications, equivalent substitutions, improvements, etc., made on the basis of the embodiments of this application should be included within the protection scope of the embodiments of this application.
