Description

Technical Field

[0001] The present invention relates to the technical field of aluminized zinc plate processing equipment, and specifically relates to a bending device for aluminized zinc plates. Background Art

[0002] In the field of metal sheet processing, aluminized zinc plates are widely used due to their excellent corrosion resistance and outstanding mechanical properties, and have become the preferred materials in many industries. Their unique coating structure not only provides durable and effective protection, enabling aluminized zinc plates to maintain stable performance in harsh environments, but also their good processability makes this kind of sheet easy to form and can meet the design requirements of various complex shapes. In addition, the production cost of aluminized zinc plates is relatively low, and the cost performance is high, further broadening their application fields.

[0003] However, although the surface finish of the coating of aluminized zinc plates is relatively high during the bending process, the zinc phase part is relatively soft. If the surface of the mold is not smooth enough or the lubrication is insufficient during bending, it is extremely easy to cause scratches or indentations on the surface of the sheet. These defects not only damage the appearance quality of the product, but also may bring potential risks to the subsequent use performance (such as reducing the corrosion resistance and affecting the structural strength, etc.). Therefore, we propose a new bending device for aluminized zinc plates. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a bending device for aluminized zinc plates, which solves the problems of scratches and indentations caused by the soft zinc phase, the non-smooth surface of the mold or insufficient lubrication during the bending process of aluminized zinc plates.

[0005] To achieve the above object, the present invention provides the following technical solution: A bending device for aluminized zinc plates, including a processing table and a groove opened at the top of the processing table, and an anti-indentation mechanism is arranged in the inner cavity of the groove.

[0006] The anti-indentation mechanism includes an H-shaped wheel frame bolted to the processing table, a shaft rod rotatably connected to the H-shaped wheel frame and passing through the H-shaped wheel frame, a roller fixedly installed on the outer circular surface of the shaft rod and adapted to the shaft rod, and a rubber sleeve sleeved outside the roller.

[0007] The anti-indentation mechanism further includes a lubricating oil tank fixedly installed at the bottom of the inner cavity of the groove, the top of the lubricating oil tank is symmetrically provided with oil suction pipes, the oil suction pipes are communicated with the inner cavity of the lubricating oil tank, the top end of the oil suction pipe is fixedly installed with a water pump, the output end of the water pump is fixedly installed with a horizontal pipe, a plurality of shunt branch pipes communicated with the inner cavity of the horizontal pipe are fixedly installed on the horizontal pipe, and the liquid outlet ends of the plurality of shunt branch pipes are fixedly installed with spray heads.

[0008] Preferably, there are two H-wheel frames, one of which is located on the left side of the top of the groove, and the other is located on the right side of the top of the groove; the highest point of the rubber sleeve is flush with the top surface of the processing table.

[0009] Preferably, a covered right-angle oil filling elbow communicating with the inner cavity of the lubricating oil tank is fixedly installed on the lubricating oil tank; the spraying port of the nozzle faces the roller.

[0010] Preferably, a V-shaped groove adapted to the groove is provided on the top of the lubricating oil tank, and a plurality of recovery pipes communicating with the inner cavity of the V-shaped groove are fixedly installed at the bottom of the V-shaped groove. The lower ends of the recovery pipes are fixedly installed on the lubricating oil tank and communicate with the inside of the lubricating oil tank; the V-shaped groove is fixedly connected to the inner wall of the groove, and the connection between the V-shaped groove and the groove is well sealed, and the oil suction pipe penetrates through the V-shaped groove.

[0011] Preferably, a top frame is fixedly installed on the top of the processing table, an electric telescopic rod is fixedly installed on the top frame, and a bent wedge block is fixedly installed at the output end of the electric telescopic rod; a galvanized-aluminum zinc plate body is arranged on the top of the processing table.

[0012] Preferably, the bent wedge block is located directly above the groove.

[0013] [[ID=!15]]Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting the roller, rubber sleeve, lubricating oil tank, oil suction pipe, water pump, horizontal pipe, shunt branch pipe and nozzle, the present invention realizes comprehensive lubrication and protection during the bending process of the galvanized-aluminum zinc plate. The rubber sleeve on the outer side of the roller can effectively avoid direct metal contact, reduce the generation of scratches and indentations; at the same time, the lubricating oil in the lubricating oil tank is evenly sprayed onto the surface of the roller through the water pump, horizontal pipe, shunt branch pipe and nozzle to form a continuous lubricating film, further reducing the friction force and reducing the risk of scratches. This design not only solves the scratch problem caused by the rough surface of the traditional bending die, but also reduces the local temperature rise and stress concentration through continuous lubrication, protecting the surface integrity and structural strength of the galvanized-aluminum zinc plate.

[0015] 2. By setting the V-shaped groove and the recovery pipe, the present invention realizes the recycling of the lubricating oil. The lubricating oil overflowed during the bending process and the lubricating oil spilled during the spraying process will flow into the V-shaped groove and return to the lubricating oil tank through the recovery pipe for the next use. This design not only reduces the consumption of lubricant and environmental pollution, but also ensures the continuous effectiveness of the lubrication system, further improving the bending quality and production efficiency of the galvanized-aluminum zinc plate.

[0024] The present invention provides a technical solution:

[0025] Please refer to Figures 1 to 5 , a bending device for a galvalume sheet, characterized in that it includes a processing table 1 and a groove 2 opened at the top of the processing table 1, and an anti-indentation mechanism 3 is arranged in the inner cavity of the groove 2

[0026] The anti-indentation mechanism 3 includes an H-shaped wheel frame 301 bolted to the processing table 1. A shaft rod 302 passing through the H-shaped wheel frame 301 is rotatably connected to the H-shaped wheel frame 301. A roller 303 adapted to the shaft rod 302 is fixedly installed on the outer circumferential surface of the shaft rod 302. A rubber sleeve 304 is sleeved outside the roller 303. The anti-indentation mechanism 3 further includes a lubricating oil tank 305 fixedly installed at the bottom of the inner cavity of the groove 2. Symmetrically installed on the top of the lubricating oil tank 305 are oil suction pipes 306. The oil suction pipes 306 communicate with the inner cavity of the lubricating oil tank 305. At the top end of the oil suction pipe 306 is fixedly installed a water pump 307. At the output end of the water pump 307 is fixedly installed a horizontal pipe 308. Fixedly installed on the horizontal pipe 308 are a number of shunt branch pipes 309 communicating with the inner cavity of the horizontal pipe 308. At the liquid outlet ends of the number of shunt branch pipes 309 are fixedly installed spray nozzles 310.

[0027] The anti-indentation mechanism 3 is fixed to the processing table 1 by bolts. Its core is supported by the H-shaped wheel frame 301. A shaft rod 302 passing through is rotatably connected to the H-shaped wheel frame 301. A rubber sleeve 304 is sleeved outside the roller 303 fixedly installed on the outer circumferential surface of the shaft rod. This design effectively avoids direct metal contact, reducing scratches and indentations. At the same time, the lubricating oil tank 305 is installed at the bottom of the inner cavity of the groove 2. Through the lubrication system composed of the oil suction pipe 306, the water pump 307, the horizontal pipe 308, the shunt branch pipes 309 and the spray nozzles 310, continuous lubrication is provided for the roller 303, forming a continuous lubricating film, further reducing the friction force and reducing the risk of scratches. The entire anti-indentation mechanism 3 plays a role of comprehensive protection and lubrication during the bending process, ensuring the integrity and structural strength of the surface of the aluminized zinc plate.

[0028] In some embodiments, the number of the H-shaped wheel frames 301 is two. One H-shaped wheel frame 301 is located on the left side of the top of the groove 2, and the other H-shaped wheel frame 301 is located on the right side of the top of the groove 2. The highest point of the rubber sleeve 3 is flush with the top surface of the processing table 1.

[0029] In this embodiment, the number of the H-shaped wheel frames 301 is set to two, which are respectively located on the left and right sides of the top of the groove, such a layout ensures that the aluminized zinc plate can be evenly stressed during the bending process. The highest point of the rubber sleeve 304 is flush with the top surface of the processing table 1, so that the aluminized zinc plate can be in smooth contact during bending, avoiding uneven stress or local compression caused by height differences. During the working process, the two H-shaped wheel frames and the rollers 303 and rubber sleeves 304 thereon jointly provide stable support and guidance for the aluminized zinc plate, effectively preventing indentations and scratches generated during the bending process. At the same time, this design also ensures the smoothness and uniformity of the bending line, improving the bending quality and surface integrity of the aluminized zinc plate.

[0030] In some embodiments, a covered right-angle oil filling elbow pipe communicating with the inner cavity of the lubricating oil tank 305 is fixedly installed on the lubricating oil tank 305. The spray port of the spray nozzle 310 is arranged facing the roller 303.

[0031] In this embodiment, a right-angle oil filling elbow with a cover is provided on the lubricating oil tank 305, which is convenient for replenishing lubricating oil. The spraying port of the nozzle 310 faces the roller 303 to ensure accurate spraying of the lubricating oil. During the working process, through this design, the roller 303 is continuously lubricated, effectively reducing the friction when bending the aluminized zinc plate, preventing scratches from occurring, while reducing local temperature rise and stress concentration, protecting the surface integrity of the plate, and improving the bending quality and production efficiency.

[0032] Please refer to Figures 2 to 5 , a V-shaped groove 311 adapted to the groove 2 is provided at the top of the lubricating oil tank 305. A plurality of recovery pipes 312 communicating with the inner cavity of the V-shaped groove 311 are fixedly installed at the bottom of the V-shaped groove 311. The lower ends of the recovery pipes 312 are fixedly installed on the lubricating oil tank 305 and communicate with the inside of the lubricating oil tank 305; the V-shaped groove 311 is fixedly connected to the inner wall of the groove 2, and the connection between the V-shaped groove 311 and the groove 2 is well sealed, and the oil suction pipe 306 penetrates through the V-shaped groove 311.

[0033] The V-shaped groove 311 at the top of the lubricating oil tank 305 is adapted to the groove 2, and the connected recovery pipe 312 at the bottom communicates with the lubricating oil tank 305 to form a lubricating oil circulation loop. During the working process, the lubricating oil overflowed and sprayed during bending all flows into the V-shaped groove 311 and flows back to the lubricating oil tank 305 through the recovery pipe 312 for recycling. This not only reduces the consumption of lubricant and environmental pollution, but also ensures the continuous effectiveness of the lubrication system. This design has good sealing performance, effectively preventing lubricating oil leakage, and plays an important role in improving the bending quality and production efficiency of aluminized zinc plates.

[0034] Please refer to Figures 1 to 2 , a top frame 4 is fixedly installed on the top of the processing table 1. An electric telescopic rod 5 is fixedly installed on the top frame 4. A bending wedge block 6 is fixedly installed at the output end of the electric telescopic rod 5; a aluminized zinc plate body 7 is arranged on the top of the processing table 1; the bending wedge block 6 is located directly above the groove 2.

[0035] The top frame 4 installed on the top of the processing table 1 bears the electric telescopic rod 5, and its output end fixes the bending wedge block 6, which is accurately corresponding to the position directly above the groove 2. During the working process, the electric telescopic rod 5 pushes the bending wedge block 6 to press vertically downwards to bend the aluminized zinc plate body 7 placed on the processing table 1. This design ensures the accurate application of force during the bending action. Combined with the anti-indentation mechanism in the groove 2, it effectively prevents indentations and scratches generated during the bending process, improves the bending quality and surface integrity of the aluminized zinc plate, and plays a key role in positioning and bending in the overall bending operation.

[0036] The working principle of the present invention is as follows:

[0037] When using this device, first place the aluminized zinc plate body 7 to be bent steadily on the top of the processing table 1, and adjust its position manually or by a positioning device to ensure that the area to be bent is accurately aligned with the bending wedge block 6 above the groove 2, and the bending line is precisely located between the two rollers 303, providing a guiding basis for the bending operation.

[0038] After the water pump 307 is started, lubricating oil is extracted from the lubricating oil tank 305 through the oil suction pipe 306, distributed to multiple shunt branch pipes 309 through the horizontal pipe 308, and finally evenly sprayed onto the surface of the roller 303 by the nozzle 310. The operator manually drives the roller 303 to rotate slowly, so that the lubricating oil fully adheres to the surface of the rubber sleeve 304 to form a continuous lubricating film. The design that the jet orifice of the nozzle 310 faces the roller 303 ensures that the lubricating oil accurately covers the rubber sleeve 304, reduces the friction force when the aluminized zinc plate body 7 contacts the roller 303, and effectively reduces the risk of scratches.

[0039] The electric telescopic rod 5 pushes the bending wedge block 6 to press down vertically, and the aluminized zinc plate body 7 gradually bends into the groove 2 under the precise application of force. The two rollers 303 play a synchronous role of support and guidance. With its high elastic modulus and smooth surface characteristics, the rubber sleeve 304 provides flexible contact during the bending deformation of the plate, avoiding surface indentations caused by rigid extrusion. At the same time, the roller 303 can rotate slightly with the bending of the plate to further disperse the stress concentration and ensure that the bending line is smooth and uniform.

[0040] The lubricating oil overflowing during the bending process and the lubricating oil spilled during the spraying process will flow into the V-shaped groove 311 and return to the lubricating oil tank 305 through the recovery pipe 312 for recycling, which not only reduces the consumption of lubricant but also reduces environmental pollution.

[0041] During the entire bending process, the anti-indentation mechanism 3 significantly improves the surface integrity of the aluminized zinc plate through the synergistic effect of the rubber sleeve 304 and the lubricating oil. The combination of the rubber sleeve 304 and the lubricating oil not only effectively isolates the direct contact of metals but also reduces the local temperature rise and friction coefficient through continuous lubrication, fundamentally solving the problem of coating damage caused by insufficient lubrication or rough molds in traditional bending processes. Finally, after bending, the aluminized zinc plate body 7 has a high dimensional accuracy while its surface is smooth and undamaged, and its corrosion resistance and structural strength are completely retained, fully meeting the stringent requirements of high-end application scenarios.

[0042] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
