Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet processing equipment, and in particular to a metal sheet rolling processing device. Background Technology

[0002] Metal sheet rolling processing equipment is a widely used piece of equipment in industrial production. It drives the metal sheet to move and bend by rotating the main drive roller, thereby processing the flat metal sheet into cylindrical or arc-shaped workpieces.

[0003] In traditional rolling processes, when the metal sheet being processed has a large diameter, long length, or is heavy, the portion of the sheet not held by the main drive roller will sag due to its own weight. This sag not only causes the final formed workpiece to have an elliptical or other irregular shape, seriously affecting the dimensional accuracy of the product, but may also cause surface scratches due to the dragging of the sheet during processing, reducing product quality. To overcome this problem, operators sometimes need to manually assist in lifting the sheet, but this not only increases labor intensity and reduces production efficiency, but also makes it difficult to ensure the consistency of processing due to the poor stability of manual operation.

[0004] Furthermore, the core transmission components of such devices, such as gearboxes, require continuous lubrication to ensure their smooth operation and service life. In existing technologies, the lubrication system design of gearboxes is often relatively simple. Dripping or splashing lubricating oil can easily come into contact with and soak the seals at the bottom of the gearbox. Over time, this can lead to aging and failure of the seal materials, resulting in oil leakage and affecting the normal operation of the equipment. At the same time, lubricating oil containing impurities such as metal shavings after use is usually directly discharged or treated as waste oil, failing to achieve effective filtration and recycling, resulting in resource waste and not meeting the requirements of green production.

[0005] Therefore, this utility model proposes a metal sheet rolling processing device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing metal sheet rolling processing device, such as the lack of effective support leading to sheet deformation when processing large-diameter workpieces, and the easy damage to seals and waste of lubricating oil due to the lubrication system, this utility model aims to provide a metal sheet rolling processing device with an improved structure that can effectively solve the above problems.

[0007] To achieve the above objectives, this utility model provides a metal sheet rolling processing device, comprising: a base and a bearing seat mounted on the base; as well as a support mechanism, a gearbox, a lubricating oil tank and a sealing and guiding mechanism.

[0008] The support mechanism is fixed to the base and includes an L-shaped bracket with a mounting groove; a servo motor located in the mounting groove and a lead screw located on the L-shaped bracket; a moving block threadedly engaged with the lead screw; and a roller rotatably mounted on the moving block via a fixed seat.

[0009] Furthermore, the gearbox is mounted on the bearing housing, the lubricating oil tank is connected to the gearbox to provide lubricating oil, and the sealing and guiding mechanism is located at the bottom of the gearbox to seal it and recover the lubricating oil.

[0010] Preferably, the support mechanism further includes a transmission assembly, which includes a first gear connected to the output end of the servo motor, a second gear connected to the lead screw, and a chain meshing with the first gear and the second gear.

[0011] Preferably, the support mechanism further includes a guide assembly, which includes a guide post disposed on the L-shaped bracket and a guide groove disposed on the movable block and slidingly engaging with the guide post.

[0012] Preferably, the support mechanism further includes a fixing component for fixing the L-shaped bracket to the base. The fixing component includes a connecting block disposed on the L-shaped bracket and a connecting groove disposed on the base for sliding connection with the connecting block. The fixing component also includes a fixing bolt for locking the connecting block in the connecting groove.

[0013] Preferably, the sealing and guiding mechanism includes a bottom cover detachably disposed at the bottom of the gearbox, and a stepped boss fixed to the top of the bottom cover for blocking lubricating oil.

[0014] More preferably, the surface of the stepped boss is provided with a flow guide groove; the sealing flow guide mechanism also includes an oil guide pipe communicating with the end of the flow guide groove, an inclined filter screen disposed between the flow guide groove and the oil guide pipe, and an oil collection box located below the oil guide pipe.

[0015] Preferably, an elastic sealing strip is provided at the connection between the bottom cover and the gearbox to enhance the sealing performance.

[0016] Preferably, the gearbox housing is provided with a pressure relief assembly, which includes a pressure relief hole penetrating the housing and a protective mesh covering the pressure relief hole, for balancing internal and external pressure and preventing impurities from entering.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of deformation, damage and low processing accuracy caused by the sag of large-diameter plates due to their own weight when processing them by setting up a roller support mechanism driven by a servo motor and a lead screw for synchronous lifting. It achieves the technical effect of providing stable support according to the size of the workpiece, effectively improving product quality and processing range.

[0018] 2. This utility model solves the problem in the prior art where lubricating oil dripping from the gearbox directly soaks the seals, causing them to age and be damaged easily, by setting a bottom cover with a stepped protrusion at the bottom of the gearbox. It achieves the technical effect of physically isolating the lubricating oil from the seals, effectively protecting the seals and extending their service life.

[0019] 3. This utility model solves the problem of waste lubricating oil that cannot be directly recycled due to impurities in the existing technology by setting a guide groove, an inclined filter screen, an oil guide pipe and an oil collection box that cooperate with the stepped boss. It achieves the technical effect of effectively filtering and cleanly recycling waste lubricating oil, making it easy to recycle and save resources. Attached Figure Description

[0023] Example: Please refer to Figures 1 to 4 This utility model provides a metal sheet rolling processing device, which aims to solve the problems of deformation of the sheet due to lack of effective support when processing large-diameter workpieces in existing metal sheet rolling processing devices, as well as the problems of lubricant pollution and waste in its lubrication system.

[0024] like Figure 1 and Figure 2 As shown, a metal sheet rolling processing device includes a base 1 serving as the mounting base for the entire device, a bearing seat 3 mounted on the base 1, and a support mechanism 2 fixed on the base 1. A gearbox 4 is mounted on the bearing seat 3. A lubricating oil tank 5 is used to supply lubricating oil to the gearbox 4. A sealing and guiding mechanism 6 is used to seal the gearbox 4 and recover the lubricating oil. The support mechanism 2 includes an L-shaped bracket 201 with a mounting groove 202. A servo motor 203 is located in the mounting groove 202. A lead screw 205 is located on the L-shaped bracket 201. A moving block 208 is threadedly engaged with the lead screw 205. A roller 210 is rotatably mounted on the moving block 208 via a fixed seat 209. The servo motor 203 drives the lead screw 205 to rotate, thereby causing the moving block 208 to move up and down in the vertical direction.

[0025] Please refer to the following carefully. Figure 1 , Figure 2 and Figure 3The internal structure of the support mechanism 2 and its connection with the base 1 are described in detail. The support mechanism 2 also includes a transmission component for driving the movement of the moving block 208, a guide component 211 for ensuring the stability of the movement of the moving block 208, and a fixing component 212 for fixing the L-shaped bracket 201 to the base 1. The fixing component 212 includes a connecting block 2121 integrally formed on the bottom of the L-shaped bracket 201. The top of the base 1 is provided with a corresponding connecting groove 2122 that slides with the connecting block 2121. The L-shaped bracket 201 is locked and fixed to the base by a fixing bolt 2123 passing through the connecting block 2121. 1. The transmission assembly includes a gear 204 fixedly connected to the output end of the servo motor 203, a gear 206 fixedly connected to the top of the lead screw 205, and a chain 207 meshing with the gear 204 and the gear 206. The guide assembly 211 includes a guide post 2111 fixedly connected to the inner wall of the L-shaped bracket 201. The moving block 208 is provided with a guide groove 2112 that slides with the guide post 2111. This sliding fit structure between the guide post 2111 and the guide groove 2112 ensures the high stability and anti-tilting ability of the moving block 208 during the up and down movement driven by the lead screw 205.

[0026] Based on the above embodiments, please refer to the following: Figure 2 and Figure 4 The sealing and guiding mechanism 6 and the pressure relief assembly 608 are described in detail below. The sealing and guiding mechanism 6 includes a bottom cover 601 detachably disposed at the bottom of the gearbox 4 and a stepped boss 602 fixed to the top of the bottom cover 601. An elastic sealing strip 603 is also provided at the connection between the bottom cover 601 and the gearbox 4. A guide groove 604 is provided on the surface of the stepped boss 602. The sealing and guiding mechanism 6 also includes an oil guide pipe 605 communicating with the end of the guide groove 604 and an oil collection box 607 located below the oil guide pipe 605. An inclined filter screen 606 is also provided between the guide groove 604 and the oil guide pipe 605. A pressure relief assembly 608 is provided on the gearbox 4 housing. The pressure relief assembly 608 includes a pressure relief hole 6081 penetrating the gearbox 4 housing and a protective net 6082 covering the pressure relief hole 6081.

[0027] Working principle: When processing large-diameter workpieces, the operator slides the connecting blocks 2121 connected to the two L-shaped brackets 201 in the support mechanism 2 to the connecting slots 2122 opened on the front and rear sides of the top of the base 1. Then, the connecting blocks 2121 are fixed to the base 1 by fixing bolts 2123, so that the fixing component 212 can complete the connection between the L-shaped brackets 201 and the base 1. Then, the servo motor 203 in the placement slot 202 opened on the adjacent side of the two L-shaped brackets 201 is started, causing the gear 1 204 to rotate, and the rotation is achieved through the gear 1 204, gear 2 206 and chain 207. The meshing connection between them causes multiple lead screws 205 located on the same side as the servo motor 203 to start rotating, thereby driving the moving block 208 to move up and down. At the same time, when the moving block 208 moves, the sliding connection between the guide post 2111 and the guide groove 2112 in the guide assembly 211 can ensure the accuracy of the position of the moving block 208 and avoid skewing. This allows the fixed seat 209 connected to the top of the two moving blocks 208 on the same side to have the roller 210 rotatably connected to its inner wall to adapt to the size of the roll material, thereby supporting the roll material and preventing it from sagging due to its own weight, thus reducing workpiece damage caused by manual alignment. Furthermore, when the gears in the gearbox 4 are lubricated via the lubricating oil tank 5 installed on the front side of the bearing housing 3, the stepped boss 602 fixedly installed on the top of the bottom cover 601 can block the lubricating oil falling below, preventing the rubber ring below from aging due to being soaked in lubricating oil. The elastic sealing strip 603 in the sealing and guiding mechanism 6 can enhance the sealing of the connection between the bottom cover 601 and the gearbox 4. The lubricating oil dripping onto the surface of the stepped boss 602 is guided by the guiding groove 604 and drips from the oil guide pipe 605 into the oil collection box 607, which is then used for subsequent lubricating oil recycling. In preparation for new utilization, before the lubricating oil enters the oil guide pipe 605 from the guide groove 604, it passes through the inclined filter screen 606 to filter impurities in the lubricating oil, so that the impurities remain at the edge of the guide groove 604, preventing impurities from clogging the oil guide pipe 605. At the same time, the pressure relief hole 6081 in the pressure relief assembly 608 can balance the pressure inside and outside the gearbox 4, and the protective net 6082 can prevent impurities in the air from entering the gearbox 4, so that the lubricating oil can drip normally, thereby achieving protection of the sealing components inside the gearbox 4, strengthening the dust prevention treatment of the lubricating oil, and reducing resource waste.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
