Description

Technical Field

[0001] This utility model belongs to the technical field of sheet metal processing equipment, and relates to slitting machine devices, and in particular to a dust cleaning device for high-precision silicon steel coil slitting line blades. Background Technology

[0002] A slitting line is a metal cutting device in which rotating blades slit sheet metal. During this process, high-speed friction between the rotating blade and the material causes surface peeling, forming metal dust and debris. This dust and debris inevitably adhere to the surface of the circular blades. Silicon steel is harder and more brittle than other materials, making it prone to dust generation during shearing. Furthermore, silicon steel requires high precision; even slight changes can affect shearing accuracy, making it particularly sensitive to variations in the blade gap. As debris accumulates between the upper and lower blades, the blade gap widens, leading to decreased processing accuracy and accelerated blade wear.

[0003] In existing technologies, traditional slitting lines require machine shutdown when cleaning the blades, or the cleaning effect is limited, failing to effectively solve the problems of dust adhesion and high temperature, resulting in low cleaning efficiency and impacting production efficiency.

[0004] Therefore, there is an urgent need in this field for a stable, uniform, efficient and clean dust cleaning device for silicon steel plate slitting blades. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a high-precision silicon steel coil slitting blade dust cleaning device that can efficiently and stably clean cutting tools.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: This high-precision silicon steel coil slitting line blade dust cleaning device includes a guide shaft disposed on one side of the blade shaft and parallel to it. At least one cleaning block fixing seat is disposed on the guide shaft and distributed along its axial direction. A blade cleaning block is detachably fixed on the cleaning block fixing seat. The outer end of the blade cleaning block can abut against the outer periphery of the circular blade. An oil supply nozzle is provided on one side of the blade cleaning block. The oil supply nozzle is connected to the oil supply mechanism through an oil supply pipe, and the oil supply pipe can be bent and maintain its shape.

[0007] A guide shaft ensures the cleaning block holder remains stable relative to the blade. The outer end of the blade cleaning block rests against the outer periphery of the circular cutter, achieving efficient cleaning of dust from the blade as it rotates. Furthermore, an oil supply mechanism ensures lubrication of the blade by the cleaning block, while simultaneously cooling the blade and maintaining stable cleaning performance. This prevents debris accumulation and blade deformation due to overheating, meeting the high shearing precision requirements of silicon steel processing.

[0008] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the oil nozzle is L-shaped with the oil outlet facing away from the circular blade. The side of the blade cleaning block is provided with a groove that allows the oil outlet end of the oil nozzle to be inserted into, providing support to the blade cleaning block while oil is being supplied. After the oil is delivered to the groove or nearby area of ​​the cleaning block, it will penetrate evenly and slowly into the contact area between the cleaning block and the circular blade through capillary action and the subsequent oil flow. This lubrication method is gentler and more uniform, resulting in better lubrication and cleaning effects, while also reducing oil consumption.

[0009] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the groove is located near the outer end of the blade cleaning block. After the lubricating oil flows out from the oil nozzle, it can quickly reach the working area where the blade cleaning block contacts the circular blade via the shortest path, shortening the distance the oil travels inside the cleaning block and reducing losses due to absorption by the material or residue in the path.

[0010] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the oil delivery pipe is a universal bamboo-joint pipe. In space-constrained situations, the oil circuit can be flexibly arranged without the need for complex adapters or custom-length rigid pipes.

[0011] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the oil supply mechanism includes an automatic oiler. The outlet of the automatic oiler is connected to an oil supply pipeline. A number of metering distributors, equal in number to the number of oil delivery pipes, are connected in parallel to the oil supply pipeline. Each metering distributor is connected to an oil delivery pipe in a one-to-one correspondence, and the metering distributors are connected to the oil delivery pipes via pipe joints. The metering distributors are fixed to one side of the cleaning block mounting base. Using metering distributors, corresponding one-to-one with each cleaning block, ensures that each blade cleaning block receives an appropriate amount of lubricating oil. This avoids the problems of some blades contaminating the silicon steel plate due to excessive oil, and blades experiencing poor cleaning performance or accelerated wear due to insufficient oil.

[0012] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, an oil supply regulating valve is connected between the pipeline joint and the oil supply pipe. Although the metering distributor ensures a basically uniform oil distribution, in actual applications, the wear, stress, or temperature of blades at different locations on the production line may vary slightly. The regulating valve can individually increase or decrease the oil supply for a specific cleaning block according to its actual needs, achieving the most precise lubrication management. This ensures that each cleaning block is in optimal working condition, thereby improving overall product quality.

[0013] In the aforementioned high-precision silicon steel coil slitting blade dust cleaning device, the cleaning block fixing seat is C-shaped, and a locking adjusting bolt with adjustable opening size is provided at the open end. A rotating handle is fixed to the outer end of the locking adjusting bolt. This allows operators to tighten and loosen the bolts by hand, further simplifying the operation process.

[0014] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, there are two blade shafts distributed vertically, and each blade shaft has a guide shaft parallel to it on one side.

[0015] The center of the upper guide axis is located in the first quadrant of the coordinate system with the center of the upper cutter axis as the origin. Its azimuth angle is on or close to the angle bisector of the X-axis and Y-axis, and its straight-line distance from the origin is greater than the radius of the circular cutter.

[0016] The center of the lower guide shaft is located in the fourth quadrant of a coordinate system with the center of the lower blade axis as the origin. Its azimuth angle lies on or near the angle bisector of the X-axis and Y-axis, and its straight-line distance from the origin is greater than the radius of the circular blade. By setting the guide shaft on the angle bisector of the X-axis and Y-axis, the blade cleaning block can contact and press against the side of the circular blade at an angle of approximately 45°, effectively peeling off and removing dust adhering to the blade without excessively wearing it down.

[0017] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the end of the blade cleaning block furthest from the circular blade is connected to the side of the cleaning block fixing seat via a clamping block, and is detachably fixed by two bolts. This detachable clamping block connection allows for the removal and replacement of only the cleaning block itself without replacing the entire fixing seat, achieving quick and reliable assembly and disassembly, and contributing to improved overall production efficiency.

[0018] In the aforementioned high-precision silicon steel coil slitting line blade dust cleaning device, the blade cleaning block is flat and thicker than the circular blade. The greater thickness of the cleaning block means it can completely cover both sides and the edge of the circular blade axially. This ensures the cleaning block is always in contact with the entire working surface of the circular blade, preventing any untreated areas from being cleaned and thus avoiding localized accelerated wear caused by dust accumulation.

[0019] The importance of cleaning blade dust lies in ensuring slitting / cutting quality. Accumulated debris on the blade edge or in the blade gaps interferes with the normal shearing flow of metal, resulting in uneven shear surfaces and increased burrs. Dust essentially adds extra friction and resistance. Furthermore, falling debris on clean coil surfaces (especially mirror-finish and coated sheets) can cause contamination, affecting subsequent processes or the final product's appearance. Debris particles caught between the running sheet and the equipment can also scratch the sheet surface.

[0020] It also extends to protecting the lifespan of the equipment. The debris, being hard particles, acts like abrasives, accelerating the wear of the blade edges. Furthermore, debris buildup between the blades increases the shearing gap, further exacerbating blade wear. All of these factors significantly reduce tool life, increasing tool change frequency and costs.

[0021] It also involves improving production efficiency and reducing costs. The accumulation of debris requires a significant investment of time and manpower to regularly shut down and clean the equipment, work areas, and dust collection systems. Furthermore, scratches, contamination, and decreased dimensional accuracy caused by dust increase scrap and rework. In addition, accelerated tool wear directly increases consumable costs.

[0022] Compared with existing technologies, the advantages of this high-precision silicon steel coil slitting line blade dust cleaning device are: 1. Stable contact between the cleaning block and the circular blade, resulting in excellent cleaning effect. 2. Intelligent lubricant distribution, ensuring stable cleaning effect. 3. Features angle adjustment and a detachable mechanism for convenient operation. Attached Figure Description

Detailed Implementation

[0029] like Figures 1 to 5 As shown, this high-precision silicon steel coil slitting line blade dust cleaning device includes a guide shaft 2 that is parallel to the blade shaft 1 on one side. Multiple cleaning block fixing seats 21 distributed along the axial direction are mounted on the guide shaft 2. Blade cleaning blocks 22 are detachably fixed on the cleaning block fixing seats 21. The outer end of the blade cleaning block 22 can abut against the outer periphery of the circular blade 11. An oil supply nozzle 31 is provided on one side of the blade cleaning block 22. The oil supply nozzle 31 is connected to the oil supply mechanism 3 through an oil supply pipe 32, and the oil supply pipe 32 can be bent and maintain its shape.

[0030] In this embodiment, the blade cleaning block 22, whose outer end abuts against the periphery of the circular blade 11, rubs against the rotating circular blade 11 to clean it. An oil supply mechanism 3 continuously delivers lubricating oil to the blade cleaning block 22, ensuring that the lubricating oil is evenly applied to the circular blade 11 during friction, thereby lubricating and cooling the circular blade 11, achieving a highly efficient and stable cleaning effect.

[0031] In this embodiment, multiple cleaning block fixing seats 21 passing through the guide shaft 2 can move along the guide shaft 2 to the required position of each circular blade 11. More than 30 pairs of cleaning devices can be installed on the guide shaft 2 at the same time to meet the needs of conventional silicon steel plate slitting.

[0032] like Figure 3 As shown, the oil nozzle 31 is L-shaped, and the oil outlet 311 faces away from the circular blade 11. The blade cleaning block 22 has a groove 221 on its side, into which the oil outlet 311 of the oil nozzle 31 can be inserted to provide support for the blade cleaning block 22 while oiling. The groove 221 is close to the outer end of the blade cleaning block 22. The oil supply pipe 32 is a universal bamboo joint pipe.

[0033] More specifically, the oil supply mechanism 3 includes an automatic oiler 33, the outlet of which is connected to an oil supply line 34. The oil supply line 34 is connected in parallel with a number of metering dispensers 35 equal to the number of oil delivery lines 32. The metering dispensers 35 are connected to the oil delivery lines 32 in a one-to-one correspondence. The metering dispensers 35 are connected to the oil delivery lines 32 through pipe joints 351. The metering dispensers 35 are fixed on one side of the cleaning block fixing seat 21.

[0034] In this embodiment, a metering distributor 35 is distributed in front of each oil delivery pipe 32, which can control the flow rate of each oil delivery pipe 32 and ensure that the dripping speed of each oil delivery pipe 32 is consistent, so as to avoid the fault phenomenon that more oil drips from nearby oil outlets and less oil drips from distant oil outlets.

[0035] In this embodiment, the automatic oiler 33 includes an oil tank 331 located at the top of one side. The oil tank 331 is connected to the oil supply pipeline 34 through a main valve 332. A liquid level detection device is provided inside the oil tank, which can start automatically and can automatically alarm when the liquid level is low.

[0036] More specifically, an oil supply regulating valve 36 is connected between the pipeline joint 351 and the oil supply pipe 32.

[0037] like Figure 2 and 3 As shown, the cleaning block fixing seat 21 is C-shaped, and a locking adjusting bolt 212 with both ends through which the size of the opening end 211 can be adjusted is provided on the opening end 211. A rotating handle 213 is fixed to the outer end of the locking adjusting bolt 212.

[0038] like Figure 2 As shown, there are two cutter shafts 1, which are distributed vertically, and each cutter shaft 1 has a guide shaft 2 on one side that is parallel to it.

[0039] The center of the upper guide axis 2 is located in the first quadrant of the coordinate system with the center of the upper cutter axis 1 as the origin. Its azimuth angle is on or close to the angle bisector of the X-axis and Y-axis, and its straight-line distance from the origin is greater than the radius of the circular cutter 11.

[0040] The center of the lower guide axis 2 is located in the fourth quadrant of the coordinate system with the center of the lower square blade axis 1 as the origin. Its azimuth angle is on or close to the angle bisector of the X-axis and Y-axis, and its straight-line distance from the origin is greater than the radius of the circular blade 11.

[0041] More specifically, the end of the blade cleaning block 22 away from the circular blade 11 is connected to the side of the cleaning block fixing seat 21 via a clamping block 222, and is detachably fixed by two bolts.

[0042] like Figure 5 As shown, the blade cleaning block 22 is flat and its thickness is greater than that of the circular blade 11.

[0043] In this embodiment, the blade cleaning block 22 is made of a wear-resistant material that can absorb lubricating oil, specifically felt.

[0044] The working principle of this embodiment is that the oil pump is driven by the drive motor at the oil tank 331 of the automatic oiler 33, and the lubricating oil is output to the metering distributor 35 through the oil supply line 34 in a timed and metered manner. There is a metering distributor 35 before each oil supply line 32. The metering distributor 35 can control the speed and flow rate of the lubricating oil delivered to each oil supply line 32.

[0045] Lubricating oil from outlet 311 drips into the blade cleaning blocks 22. Each blade cleaning block 22 can be moved to a corresponding position on the circular cutter 11 via guide shaft 2, and its angle can be adjusted by rotating handle 213. When the circular cutter 11 rotates, the blade cleaning blocks 22 will fit tightly against the two sides and the edge of the circular cutter 11. Through the rotation of the circular cutter 11, the blade cleaning blocks 22 continuously wipe away the dust adhering to the circular cutter 11, while simultaneously lubricating the circular cutter 11 and controlling its temperature, reducing dust generated during the shearing process and improving machining accuracy.
