Description

Technical Field

[0001] This utility model belongs to the technical field of steel plate shearing equipment, specifically relating to the oil storage box of the splitting shear frame. Background Technology

[0002] Heavy steel plates are key materials in major equipment manufacturing, building structures, and energy sectors. Their shape quality and surface cleanliness directly affect the performance and grade of end products. In recent years, with the vigorous development of my country's high-end manufacturing industry, the market has placed unprecedentedly high standards on the surface quality of heavy steel plates. Any surface defects can lead to product downgrading and cause significant economic losses.

[0003] The slitting shear is a core piece of equipment in the finishing production line for heavy plates, responsible for the precise online slitting of steel plates moving at high speeds. Its working principle is typically rolling shearing, during which high-frequency relative sliding occurs between the upper blade holder and the carriage, generating enormous friction. To ensure stable equipment operation, reduce wear, and extend the lifespan of core components, continuous and adequate grease lubrication of this friction pair is essential.

[0004] However, with existing lubricating greases, excess grease squeezed out during use cannot be effectively contained or collected. Under the influence of equipment vibration and movement, this grease will inevitably drip or splash onto the surface of the steel plate passing below at high speed, causing contamination of the plate surface and directly resulting in quality defects. In subsequent processes (such as straightening, cooling, and stacking), the grease contaminants will firmly bond to the plate surface or be pressed into the plate surface, forming irreversible oil stains, causing the product to be downgraded or scrapped due to unqualified surface quality.

[0005] Furthermore, contaminated panels may affect the adhesion and quality of subsequent deep processing steps such as spraying and plating. In order to deal with such contamination, some production lines have to add additional panel cleaning devices or manual cleaning steps, which increases operating costs and complexity. Utility Model Content

[0006] The purpose of this invention is to provide an oil storage box for a splitting shear frame, which solves the problem in the prior art of lubricating grease dripping onto the surface of the steel plate, causing defects in the steel plate quality.

[0007] The technical solution adopted by this utility model is a split scissor frame oil storage box, including a shell, an opening at the top of the shell for use as an oil inlet, a connecting block fixed on one side of the shell, a magnet for adsorbing the connecting block on the top, a filter assembly for filtering lubricating oil inside the shell, an oil storage area below the filter assembly, a liquid level sensor for monitoring the oil level in the oil storage area on the inner wall of the shell, and an oil drain and a motor at the bottom of the shell relative to the oil storage area. The motor is connected to a stirring plate inside the shell.

[0008] The present invention is further characterized in that, The filter assembly includes two filter plates arranged from top to bottom. Both filter plates are inclined, and a slag collection box is movably connected to the lower end of the housing near the filter plates. A filter screen is installed in the middle of the filter plate, and the pore size of the filter screen in the lower filter plate is smaller than that in the upper filter screen.

[0009] A scraper is installed above the filter screen, and the two ends of the scraper are movably connected to the filter screen.

[0010] The filter plate has a groove a along the scraper's movement path on the opposite side. A slider is movably connected in the groove a. The slider is fixedly connected to the corresponding scraper end. A brush is provided on the side of the scraper opposite to the filter screen.

[0011] A groove b is provided on the front side of the housing relative to the groove a. The groove b is in the same direction and has the same length as the groove a. A sliding handle is fixedly connected to the slider near the groove b. The outer end of the sliding handle passes through the groove b.

[0012] Four rectangular fixing blocks are arranged on the inner wall of the housing relative to the two sides of the filter plate. The fixing blocks on both sides of the housing have slots on their opposite surfaces. The clamping plates at both ends of the filter plate are adapted to the slots.

[0013] The slag collection box is an outer shell with an opening near the filter plate end and the top end. A filter screen strip is fixedly connected to the bottom plate of the slag collection box near the side of the filter plate. The filter screen strip fits into the filter screen, and a handle is installed on the side of the slag collection box away from the filter plate.

[0014] The motor is located at the center of the bottom of the housing, and its output shaft passes through the housing and is connected to the stirring shaft. The stirring blades surround the outside of the stirring shaft and are fixedly connected to the stirring shaft.

[0015] A control valve is installed on the housing relative to the oil drain port.

[0016] The beneficial effects of this utility model are: (1) This utility model uses the oil inlet on the top of the housing to precisely align with the friction pair area of ​​the upper tool holder and the slide, and with the magnet on the top of the connecting block, it achieves rapid adsorption and fixation of the device and the slide. It can stably fit the equipment without the need for a complicated installation structure, and completely confines the excess grease that is squeezed out inside the housing, thus preventing the grease from dripping or splashing onto the surface of the steel plate passing at high speed below due to equipment vibration and movement. It solves the core problem of grease contamination of the plate surface in traditional lubrication methods, which leads to product downgrading and scrapping. At the same time, it avoids the hidden danger of oil stains on the plate surface affecting the adhesion of spraying and plating in subsequent deep processing processes, ensuring the surface cleanliness and product grade of the thick plate.

[0017] (2) The internal filter assembly of this utility model adopts a top-down double-layer inclined filter plate design, combined with filter screens of different pore sizes to achieve graded filtration of lubricating grease, effectively intercepting impurity particles in the grease, ensuring the cleanliness of the recovered lubricating grease, and providing a basis for subsequent reuse; the inclined structure, combined with the setting of the slag collection box, allows the impurities trapped by the filter to slide naturally into the slag collection box under the action of gravity, and the slag collection box can be removed by the handle without disassembling the device to complete the cleaning. At the same time, the scraper above the filter screen is linked to the sliding handle through the sliding groove, which can manually drive the brush to clean the attached impurities on the filter screen, avoid the filter screen clogging and affect the filtration efficiency, significantly improve the convenience of maintenance, and reduce the equipment operation and maintenance costs.

[0018] (3) The liquid level sensor on the inner wall of the housing of this utility model can monitor the oil level in the oil storage area in real time, so that the staff can keep track of the grease storage status in a timely manner and avoid the grease leakage caused by the overflow of the oil storage area and the pollution caused again; the oil drain port at the bottom of the housing, together with the control valve, can discharge the recovered grease as needed according to the oil level monitoring results, so as to realize the orderly recovery or replacement of grease, and the operation is flexible and controllable.

[0019] The filter plate is connected to the slots of the fixing block inside the housing by the clamping plates at both ends, which enables quick disassembly and assembly, and facilitates the replacement and maintenance of the filter screen. The modular design of components such as the slag collection box and filter plate allows for maintenance without the need for professional tools, which greatly shortens maintenance time and reduces the frequency of production line downtime.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1 This utility model relates to an oil storage box for slitting shears, specifically designed for collecting excess lubricating grease from the friction pair between the blade holder and the slide of the slitting shears. Figure 1 and Figure 2 As shown, the core structure and connection relationships are as follows: The main body of the device is a one-piece molded shell 1, which serves as the overall load-bearing foundation. An open oil inlet 6 is provided on its top, precisely corresponding to the relative sliding area between the upper tool holder 24 and the slide 25. This inlet can fully collect any extruded grease, preventing leakage. One side of the shell 1 is securely connected to a connecting block 2. The connecting block 2 extends upwards along the side of the shell 1, and a magnet 3 is embedded in its top. The magnet 3's attraction allows for quick and detachable fixing of the device to the slide 25, adapting to the high-frequency vibration environment of the equipment and ensuring it is not easily loosened after installation. The connecting block 2 is made of metal, facilitating the removal and disassembly of the magnet 3. The magnet 3 is a powerful magnet, improving stability during attraction. Additionally, the connecting block 2 has an open screw hole; when the magnet on the surface of the slide 25 cannot stably attract the grease, bolts or screws can be used to fix the connection to the slide 25.

[0024] Inside the housing 1, below the oil inlet 6, is a filter assembly 4. This filter assembly 4 is arranged horizontally inside the housing 1 to filter impurities from the grease entering the housing, ensuring the cleanliness of the grease. Directly below the filter assembly 4, a closed oil storage area is formed, serving as a collection and storage space for the filtered, pure grease. A level sensor 5 is fixedly installed on the inner wall of the housing 1 at a suitable height corresponding to the oil storage area. The level sensor 5 can monitor the grease level in the oil storage area in real time, providing accurate information for subsequent oil draining operations.

[0025] The bottom of the housing 1 is provided with an oil drain port 7 corresponding to the oil storage area, which is used to drain the lubricating grease collected in the oil storage area. At the same time, a motor 21 is also fixedly installed at the bottom of the housing 1. The output end of the motor 21 extends into the oil storage area and is connected to the stirring plate 22 set in the oil storage area. The stirring plate 22 is driven to rotate by the motor 21, which can prevent the lubricating grease from solidifying due to long-term static storage and ensure its fluidity and reusability.

[0026] Example 2 This utility model discloses a split scissor holder oil storage box, including a housing 1. The upper opening of the housing 1 serves as an oil inlet 6. A connecting block 2 is fixed on one side of the housing 1. A magnet 3 is provided on the top of the connecting block 2 for adsorption with the slide 25. A filter assembly 4 for filtering lubricating oil is provided inside the housing 1. Below the filter assembly 4 is an oil storage area. A liquid level sensor 5 for monitoring the oil level in the oil storage area is provided on the inner wall of the housing 1. An oil outlet 7 and a motor 21 are provided at the bottom of the housing 1 relative to the oil storage area. The motor 21 is connected to a stirring blade 22 provided inside the housing 1.

[0027] Furthermore, such as Figure 3 As shown, the filter assembly 4 includes two filter plates 9 arranged sequentially from top to bottom. Both filter plates 9 adopt an inclined design adapted to the flow characteristics of lubricating grease and the settling law of impurities. The inclined arrangement can efficiently guide metal debris, dust and other impurities trapped during the filtration process to slide naturally to the lower end of the filter plate 9 by gravity, avoiding the accumulation of impurities on the surface of the filter screen 20 and causing blockage of the filter channel, thus ensuring the continuous and stable filtration efficiency. The end of the housing 1 near the lower position of the filter plate 9 adopts a movable connection structure with the slag collection box 16. This connection method allows the slag collection box 16 to be quickly disassembled and assembled. The operator can directly remove the slag collection box 16 to clean the internal impurities without disassembling the entire filter assembly 4, which greatly reduces the maintenance difficulty and downtime.

[0028] The middle section of filter plate 9 is a dedicated installation area for filter screen 20. Filter screen 20 is securely assembled with filter plate 9 by embedding or pressing, ensuring that it is not easily loosened or detached during grease impact, equipment vibration, and subsequent cleaning, thus improving structural reliability. The filter screens 20 equipped on the two layers of filter plates 9 adopt a differentiated pore size design, with the pore size of the filter screen 20 on the lower filter plate 9 being smaller than that on the upper filter plate 9, forming a graded filtration system of "coarse filtration-fine filtration": the upper filter screen 20 first intercepts larger impurities in the grease, reducing the direct impact and clogging risk of large particles on the lower fine filter screen 20, effectively extending the service life of the fine filter screen 20; the lower fine filter screen 20 further traps the small impurities that were not filtered out by the upper layer, achieving deep purification of the grease, ensuring that the grease flowing into the oil storage area has good cleanliness and meets the lubrication performance requirements for subsequent recycling and reuse.

[0029] Example 3 This embodiment is based on the above embodiment 2, such as Figure 4 As shown, in this utility model, a scraper 12 for cleaning impurities attached to the surface of the filter screen 20 is provided above the filter screen 20. The two ends of the scraper 12 are movably connected to the filter plate 9 to ensure that the scraper 12 can move smoothly along the surface of the filter screen 20 and avoid the filter screen 20 from being blocked by the accumulation of impurities, which would affect the filtration efficiency.

[0030] On the opposite side walls of the filter plate 9, grooves a10 are provided along the preset movement path of the scraper 12. The grooves a10 provide precise guidance for the movement of the scraper 12, and their length is adapted to the cleaning stroke of the scraper 12. A slider 11 is movably embedded in the groove a10. The slider 11 is fixedly connected to the end of the corresponding scraper 12, so that the slider 11 can drive the scraper 12 to slide synchronously along the groove a10. A brush is fixedly mounted on the side of the scraper 12 facing the filter screen 20. The bristles of the brush are in close contact with the surface of the filter screen 20, ensuring that the scraper 12 can fully sweep away the trapped impurities on the surface of the filter screen 20 when it moves, and push the impurities to the lower end of the filter plate 9 so that they can be collected into the slag collection box 16 later, further ensuring the permeability of the filter screen 20.

[0031] Example 4 This embodiment is based on the above embodiment 3, such as Figure 5 As shown, a groove b13 is provided on the front side of the housing 1 of this utility model, corresponding to the position of the groove a10. The groove b13 and the groove a10 are arranged in the same direction and have the same length, ensuring that the movement stroke of the slider 11 is precisely matched with the cleaning range of the scraper 12. A sliding handle 19 is mounted on the slider 11 near the groove b13 using a stable fixed connection. The outer end of the sliding handle 19 passes through the groove b13 and extends to the outside of the housing 1, making it convenient for the operator to directly operate the scraper 12 from the outside of the equipment. The groove b13 not only provides a stable movement guide for the sliding handle 19, but also forms a bidirectional limiting cooperation with the groove a10 to prevent the scraper 12 from deviating or getting stuck during movement, ensuring the smoothness and reliability of the cleaning operation of the impurities on the surface of the filter screen 20.

[0032] Example 5 Based on Embodiment 4 above, this embodiment features four rectangularly distributed fixing blocks 14 symmetrically arranged on the inner wall of the housing 1 corresponding to both sides of the filter plate 9. These blocks provide uniform support for the filter plate 9, preventing deformation or displacement during grease impact, high-frequency vibration of the equipment, and cleaning operations by the scraper 12. This ensures the stability of the filter plate 9's tilt angle, thereby guaranteeing impurity slippage and filtration efficiency. The fixing blocks 14 arranged opposite each other on the side walls each have a slot 15 on their opposite surfaces that matches the installation direction of the filter plate 9. The width and depth of the slot 15 precisely match the locking plates 23 at both ends of the filter plate 9, using a clearance fit. This facilitates quick insertion and installation of the filter plate 9 while also restricting its displacement through the side walls of the slot 15, preventing the filter plate 9 from shifting during equipment operation.

[0033] Furthermore, the slag collection box 16 is designed as a box-shaped shell with openings at one end near the filter plate 9 and at the top. Its external dimensions are precisely matched with the corresponding installation cavity inside the shell 1, ensuring that it fits tightly against the inner wall of the shell 1 after assembly, and preventing impurities from falling out due to gaps.

[0034] The bottom plate of the slag collection box 16 is close to the side of the filter plate 9, and a filter screen strip 18 is fixedly connected thereto. The filter screen strip 18 is made of a wear-resistant material that is compatible with the material of the filter screen 20 and has a certain degree of elasticity. Its length is consistent with the width of the filter plate 9. After installation, the upper surface of the filter screen strip 18 is tightly attached to the edge of the filter screen 20 to form a seamless connection structure, which prevents small impurities from leaking out from the gaps, and avoids hard contact that could cause wear to the edge of the filter screen 20 through elastic contact.

[0035] In addition, a handle 17 is fixedly installed on the side of the slag collection box 16 away from the filter plate 9 by welding or threaded connection. The handle 17 adopts an ergonomic structural design, and the size and shape of its grip part are adapted to the operating habits of the staff, making it easy to quickly pull out the slag collection box 16 in the narrow space inside the equipment.

[0036] Example 6 Based on Embodiment 5 above, in this embodiment, the motor 21 of the present invention is fixedly installed at the center of the bottom of the housing 1. This installation layout enables the stirring shaft 26 to drive the stirring blade 22 to form a uniform stirring range in the oil storage area, ensuring that the grease in all parts of the oil storage area can be fully stirred.

[0037] The output shaft of motor 21 passes vertically through a pre-drilled mounting hole at the bottom of housing 1 and is coaxially and fixedly connected to the stirring shaft 26 located inside the oil storage area, ensuring the stability and reliability of power transmission and preventing shaft loosening or slippage during high-speed stirring. The stirring blades 22 are evenly distributed and fixedly connected along the axial and circumferential directions of the stirring shaft 26.

[0038] A control valve 8 is fixedly installed at the installation position of the housing 1 corresponding to the oil drain port 7. The control valve 8 and the oil drain port 7 are connected in a sealed manner to ensure that there is no risk of grease leakage at the connection.
