Description

Technical Field

[0001] This invention relates to the field of metal cutting apparatus, and more particularly to a cutting apparatus for ferrous metal smelting and rolling products. Background Technology

[0002] Ferrous metal smelting and rolling products (such as various steel plates, strips, and sections) are indispensable basic raw materials in modern manufacturing, construction engineering, and transportation. In their subsequent processing, precise and efficient cutting of the rolled products according to usage requirements is an essential key step. Cutting quality directly determines the dimensional accuracy and edge quality of the final product, while cutting efficiency affects the overall production line capacity and cost. As ferrous metal smelting and rolling products develop towards higher strength, higher hardness, and larger sizes, traditional cutting methods can no longer simultaneously meet the stringent requirements of high precision, high efficiency, and low tool wear. Therefore, developing a device capable of continuously, stably, and with high quality cutting of ferrous metal smelting and rolling products is of significant practical importance for improving the overall processing level of the industry.

[0003] Chinese Patent No. CN219852345U discloses a cutting device for ferrous metal smelting and rolling strips, including a base, a mounting frame fixed to the top of the base, a protective plate fixed to the other side of the connecting plate, an electric telescopic rod installed at the top of the mounting frame, a cutting blade installed at the bottom of the electric telescopic rod, a support column fixed to one side of the bottom of the base, a collecting structure provided in the middle of the bottom of the base, and a limiting structure provided on the other side of the top of the base.

[0004] Existing cutting devices for ferrous metal smelting and rolling strips have significant shortcomings: First, they are equipped with only a single cutting blade, which wears down extremely quickly when cutting high-hardness ferrous metal rolled strips, requiring frequent machine stops for blade replacement or resharpening, severely disrupting production continuity. Second, they lack online grinding, cleaning, and cooling functions for the blades, making it impossible to restore blade sharpness synchronously during the cutting process, resulting in a rapid decline in cutting quality as the blades become dull. Third, their limiting structure can only achieve simple width positioning and cannot accurately position and move the rolled strips from multiple directions (such as edge clamping, multi-directional feeding, etc.), making them prone to slippage and deviation when cutting thick plates or high-strength materials. Therefore, there is an urgent need for a new type of device that can improve cutting efficiency and quality through multi-station switching, synchronous grinding and cleaning, and multi-directional positioning and movement. Summary of the Invention

[0008] Preferably, the adjustment assembly includes a rotating shaft rotatably mounted on the top of the notch; an adjustment frame is provided at the head end of the rotating shaft; a lifting block that moves up and down is provided on the adjustment frame; two sets of telescopic rods are respectively horizontally placed on both sides of the adjustment frame, one end of each set of telescopic rods is connected to the lifting block, and the other end is connected to the mounting sleeve; pairs of disc cutters are rotatably mounted in the two sets of mounting sleeves, corresponding to each other.

[0009] Preferably, a miniature compressor is installed on the mounting sleeve, and an air outlet head 1 that directs air towards the disc blade is installed inside the mounting sleeve, while an air outlet head 2 that directs air up and down is installed on the sleeve opening; both the air outlet head 1 and the air outlet head 2 are matched with the miniature compressor.

[0011] Preferably, the wall of the grinding and cleaning tank is set as an arc-shaped structure that matches the outer edge of the cutting disc; the exhaust head is set along the arc-shaped tank wall; and the grinding head is set on both sides of the exhaust head.

[0012] Preferably, a slag collection cylinder is provided on the side of the grinding and cleaning disc away from the cutting disc; the slag collection cylinder is connected to the exhaust head through a pipe, and a filter element is installed inside the slag collection cylinder; the exhaust pump is installed on the cylinder wall of the slag collection cylinder; the filter element is located between the exhaust pump and the pipe.

[0013] Preferably, the positioning and moving component includes a positioning and moving frame that moves horizontally on both sides of the cutting groove; the cutting grooves on both sides are U-shaped structures with openings facing each other, and a positioning table and a moving part are provided on the cutting grooves.

[0014] Preferably, the moving part includes a rotating disk driven by a second motor to rotate on the top wall of the cutting groove; both sides of the rotating disk are provided with moving blocks that can move back and forth; the bottom of each set of moving blocks is provided with a telescopic rod; a rotatable moving positioning roller is provided between the two sets of telescopic rods; multiple sets of positioning platforms are spaced and embedded at the bottom of the cutting groove, opposite to the moving part, and are of a liftable structure.

[0015] Preferably, a chip collection port is provided on the cutting groove; the chip collection port is located between the positioning and moving components on both sides; and a chip collection box communicating with the chip collection port is provided at the bottom of the cutting table.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: This invention achieves rapid overall rotation and station switching of multiple pairs of disc cutters by rotating the cutting disc between two sets of grinding and cleaning components and setting multiple pairs of adjustable components on the outer periphery of the cutting disc. This allows cutting and grinding / cleaning to be performed simultaneously. When one pair of disc cutters is continuously cutting ferrous metal smelting rolled products at the lower cutting station, the other pair of worn disc cutters can be immediately rotated upwards to the grinding and cleaning components for grinding, cleaning, and cooling. Meanwhile, the pre-ground disc cutters are simultaneously rotated into the cutting station, forming a seamless closed loop of "cutting-switching-grinding-standby-recutting". Because ferrous metal smelting rolled products have high hardness and cause severe wear on the cutting tools, frequent shutdowns for tool replacement or re-grinding would severely disrupt the production process if forced station switching were not implemented. This invention utilizes the rotation switching function of the cutting disc to avoid downtime and significantly improve continuous operation capability. At the same time, the horizontal movement of the grinding and cleaning component along the moving track is coordinated with the rotation of the cutting disc to ensure that the disc cutter at any station can accurately enter the grinding and cleaning tank, realizing synchronous grinding without stopping the machine, and significantly reducing quality problems such as cutting burrs and dimensional deviations caused by tool dulling. The necessity of station switching is also reflected in the synergistic effect of the adjustment and grinding / cleaning components. When the disc cutter rotates into the grinding / cleaning station with the cutting disc, the telescopic rod one in the adjustment component retracts, the lifting block moves upward, and the disc cutter is precisely fed into the grinding / cleaning tank. The grinding head grinds the blade from both sides, while the exhaust head and exhaust head two form an air curtain to prevent debris from spilling out. This process runs parallel to the continuous operation of the cutting station without pausing the entire machine. Multiple adjustment components are installed on the cutting disc, allowing each pair of disc cutters to independently adjust the spacing, height, and angle, adapting to the cutting needs of different specifications of rolled products and quickly restoring cutting parameters after station switching. When a pair of disc cutters has cut for a preset time or when blade wear is detected, the drive cylinder can rotate the cutting disc. This forced periodic switching mechanism, combined with exhaust heads one and two on the mounting sleeve, provides real-time cooling and cleaning for the cutting and grinding process, effectively preventing high-temperature adhesion of ferrous metal chips or overheating and annealing of the blades.

[0018] Example 1, as Figures 1-3 As shown, the present invention proposes a cutting device for ferrous metal smelting and rolling products, including a cutting table 1, a cutting structure, a disc cutter 8, and a positioning and moving component 4. A cutting table 1 is provided with a cutting groove 101 and supports 2 located on both sides of the cutting groove 101; two sets of supports 2 are provided with moving rails 5; the cutting structure is located above the cutting groove 101, including two sets of grinding and cleaning components 6 that move horizontally synchronously along the moving rails 5 and a cutting disc 7 located between the two sets of grinding and cleaning components 6; the cutting disc 7 rotates around the moving rails 5 and the grinding and cleaning components 6 to switch cutting positions, and multiple sets of adjusting components 10 are provided on its outer periphery; multiple sets of grinding and cleaning ends are provided on the grinding and cleaning components 6; two pairs of disc cutters 8 work together, and each pair of disc cutters 8 is respectively provided on multiple sets of adjusting components 10. The adjusting components 10 adjust the cutting spacing, height and angle of each pair of disc cutters 8, and the grinding and cleaning ends grind, clean and cool each pair of disc cutters 8; the positioning and moving components 4 are located on the two side walls of the cutting groove 101, and position and move the ferrous metal smelting and rolling products from multiple directions during cutting.

[0019] like Figures 4-5 As shown, the center of the cutting disc 7 is provided with a drive cylinder 702 that is penetrated by the moving track 5 and rotatably connected to the polishing and cleaning component 6, and the outer periphery is provided with a notch 701 for the installation of the adjustment component 10.

[0020] The drive cylinder 702 is equipped with a combination of gears, a gear ring, and a motor structure, which drives the cutting disc 7 to rotate between the two sets of grinding and cleaning components 6, allowing multiple pairs of disc blades 8 to rotate as a whole. The disc blade 8 used for cutting moves to the lower position, while the other disc blades 8 remain in a standby state for easy switching. The grinding and cleaning components 6 drive the cutting disc 7 to move horizontally, which allows adjustment of the cutting end position to match cutting requirements.

[0021] like Figure 6 As shown, the adjustment assembly 10 includes a rotating shaft 1001 driven by a motor and rotatably mounted on the top of the notch 701; an adjustment frame 1002 is mounted at the head end of the rotating shaft 1001; a lifting block 1003 that moves up and down is mounted on the adjustment frame 1002; two sets of telescopic rods 1004 are horizontally placed on both sides of the adjustment frame 1002, with one end of each set of telescopic rods 1004 connected to the lifting block 1003 and the other end connected to the mounting sleeve 1005; and pairs of disc cutters 8 are rotatably mounted in the two sets of mounting sleeves 1005.

[0022] The rotation of the pivot 1001 allows for synchronized rotation of the disc cutter 8. The rotation trajectory during cutting is related to the length of the corresponding telescopic rod 1004. The extension and retraction of the two sets of telescopic rods 1004 adjusts the distance between the disc cutters 8, thus adjusting the cutting width. The cutting process can also be combined with the horizontal movement of the cutting disc 7 to enhance cutting flexibility. The raising and lowering of the two sets of telescopic rods 1004 can adjust the cutting depth and, by changing the position of the disc cutter 8, switch between cutting (contacting ferrous metal smelting and rolling products) and grinding (entering the grinding and cleaning end).

[0023] like Figure 7 As shown, a miniature compressor 1008 is installed on the mounting sleeve 1005. An air outlet 1006 that supplies air to the disc blade 8 is installed inside the mounting sleeve 1005, and an air outlet 1007 that supplies air up and down is installed on the sleeve opening. Both the air outlet 1006 and the air outlet 1007 are matched with the miniature compressor 1008.

[0024] During cutting, exhaust head 1006 directs air towards the disc cutter 8 to cool and clean it, while exhaust head 1007, pointing downwards, cools and cleans the cutting area. During grinding, exhaust head 1006 directs air towards the disc cutter 8 to cool and clean it, while exhaust head 1007, pointing upwards, cools and cleans the grinding area. This reduces contamination from chips and grinding debris and minimizes the impact of high temperatures during cutting and grinding on the disc cutter 8.

[0025] like Figure 8 As shown, the polishing and cleaning assembly 6 includes a polishing and cleaning disc 601 slidably mounted on the moving track 5; a polishing and cleaning groove 603 is provided on the outer periphery of the polishing and cleaning disc 601, and an air pump 607 is provided on one side of the polishing and cleaning disc 601; the polishing and cleaning groove 603 is the polishing and cleaning end, and a retractable polishing head 605 and an exhaust head 604 connected to the air pump 607 are provided in the groove; as the cutting disc 7 rotates, the disc blade 8 and the polishing and cleaning groove 603 are positioned in a one-to-one correspondence.

[0026] It should be further explained that the polishing and cleaning disc 601 is provided with a guide rod 9 parallel to the moving track 5; the end of the guide rod 9 slides through the bracket 2 on the same side.

[0027] After cutting for a period of time, the disc cutter 8 will become worn. The worn disc cutter 8 can be moved out of the cutting station by rotating the cutting disc 7 for grinding and cleaning. Alternatively, grinding and cleaning can be performed on-site at the cutting station.

[0028] During grinding and cleaning, the disc cutter 8 moves into the grinding and cleaning tank 603 under the action of the mounting sleeve 1005, where it can be ground by the grinding head 605. The grinding debris is sucked away by the exhaust fan 604, while the second exhaust fan 1007 blows air towards the opening of the grinding and cleaning tank 603 to reduce debris spillage. The first exhaust fan 1006 further cleans and cools the disc cutter 8.

[0029] It should be further explained that the wall of the grinding and cleaning tank 603 is set as an arc-shaped structure that matches the outer edge of the cutting disc 7; the exhaust head 604 is set along the arc-shaped tank wall; and the grinding head 605 is set on both sides of the exhaust head 604.

[0030] The disc cutter 8 enters the grinding and cleaning tank 603, and the grinding head 605 grinds it from both sides. The exhaust fan 604 cleans it in time to prevent debris from adhering and affecting the cutting effect of the disc cutter 8.

[0031] It should be further explained that a slag collection cylinder 602 is provided on the side of the grinding and cleaning disc 601 away from the cutting disc 7; the slag collection cylinder 602 is connected to the exhaust head 604 through a pipe, and a filter element 606 is provided inside the slag collection cylinder 602; the air pump 607 is provided on the cylinder wall of the slag collection cylinder 602; the filter element 606 is located between the air pump 607 and the pipe.

[0032] By setting up filter element 606, the debris sucked into the slag collection cylinder 602 is intercepted and filtered, reducing environmental pollution during the cutting process.

[0033] like Figures 9-10 As shown, the positioning and moving assembly 4 includes a positioning and moving frame 401 that is driven by a cylinder 402 to move horizontally on both sides of the cutting groove 101; the cutting grooves 101 on both sides are U-shaped structures with openings facing each other, and a positioning platform 403 and a moving component are provided on the cutting grooves 101.

[0034] Before cutting, the ferrous metal smelting and rolling product is placed between the positioning and moving frames 401 on both sides and inserted into the U-shaped structure for positioning. The spacing is adjusted to match the width of the ferrous metal smelting and rolling product by moving the positioning and moving frames 401 on both sides.

[0035] It should be further explained that the moving part includes a rotating disk 405 driven by motor 404 to rotate on the top wall of the cutting groove 101; both sides of the rotating disk 405 are provided with moving blocks that can move back and forth; the bottom of both sets of moving blocks is provided with telescopic rods 406; a rotatable moving positioning roller 407 is provided between the two sets of telescopic rods 406; multiple sets of positioning platforms 403 are spaced and embedded in the bottom of the cutting groove 101, opposite to the moving part, and are of a liftable structure.

[0036] During cutting, the descending positioning roller 407 presses down on the upper edge of the ferrous metal smelting rolled product, achieving positioning. By rotating the positioning roller 407 in the width direction of the ferrous metal smelting rolled product, it can be pushed horizontally; by rotating the positioning roller 407 in the length direction, it can be pushed back and forth, achieving multi-directional feeding. Meanwhile, the positioning table 403 rises during lateral feeding, which can hold the outer edge of the outward-moving ferrous metal smelting rolled product, further positioning it.

[0037] like Figure 1 and Figure 3 As shown, a chip collection port 102 is provided on the cutting groove 101; the chip collection port 102 is located between the positioning and moving components 4 on both sides; a chip collection box 3 communicating with the chip collection port 102 is provided at the bottom of the cutting table 1.

[0038] It should be further noted that the chip collection box 3 is designed with a negative pressure structure.

[0039] When cutting, chips are generated. Chips from ferrous metal smelting and rolling products are hard. They can be fed downwards by the exhaust head 1007, causing them to fall into the chip collection port 102 and enter the chip collection box 3, thus achieving the purpose of collecting chips.

[0040] Example 2: Based on the ferrous metal smelting and rolling product cutting device in Example 1, this example proposes a method for cutting ferrous metal smelting and rolling products, the steps of which are as follows: S1. Pre-adjustment of cutting parameters and initialization of the cutting station: Based on the width, thickness, and cutting angle requirements of the ferrous metal smelting and rolling product to be cut, the motor in the adjustment assembly 10 first drives the rotating shaft 1001 to rotate, thereby adjusting the adjustment frame 1002 to adjust the overall cutting angle of the disc cutter 8; at the same time, the two sets of telescopic rods 1004 are driven to extend and retract, precisely adjusting the lateral spacing of the disc cutter 8 within the mounting sleeve 1005 to match the cutting width; then, the lifting block 1003 moves up and down along the adjustment frame 1002 to set the cutting depth of the disc cutter 8. After the adjustment is completed, the motor and gear ring structure on the drive cylinder 702 are started, driving the cutting disc 7 to rotate between the two sets of grinding and cleaning assemblies 6, switching the pair of disc cutters 8 with the adjusted parameters to the lower cutting station, while the remaining disc cutters 8 rotate to the standby station or the grinding and cleaning station, realizing rapid preparation of multiple stations and laying the foundation for the subsequent simultaneous cutting and grinding; S2. Multi-directional positioning and continuous feeding of ferrous metal smelting rolled products: The ferrous metal smelting rolled products are placed on the cutting table 1, with their two side edges extending into the U-shaped structure with opposite openings on both sides of the cutting groove 101. The positioning and moving assembly 4 is activated, and the cylinder 402 drives the positioning and moving frame 401 to move horizontally, so that the two side positioning and moving frames 401 clamp the rolled products from the width direction; then, the multiple sets of positioning platforms 403 at the bottom of the cutting groove 101 rise up and hold the outer edge of the rolled products; at the same time, the motor 404 in the moving component drives the rotating disk 405 to rotate, so that the moving block drives the telescopic rod 406 and the moving positioning roller 407 to descend and press down on the upper edge of the rolled products. When feeding is required, the moving positioning roller 407 rotates actively according to the cutting direction, pushing along the width direction of the rolled product to achieve transverse feeding and pushing along the length direction to achieve longitudinal feeding. Thus, the high-hardness ferrous metal smelting rolled product is stably positioned and accurately moved from multiple directions during the cutting process, avoiding cutting deviations caused by the high hardness of the material and its tendency to slip under force. S3. Synchronous operation of cutting and grinding and forced station switching: During the cutting process, the pair of disc cutters 8 located at the lower cutting station continuously cut the ferrous metal smelting and rolling products. Alternatively, only one side of the disc cutter 8 can be used for continuous cutting (the other side of the disc cutter 8 is raised). At the same time, due to the severe wear of the cutting tools caused by ferrous metals, station switching must be performed to ensure cutting quality and continuous production without stopping the machine: When a pair of disc cutters 8 has cut for a preset time or when blade wear is detected, the drive cylinder 702 immediately drives the cutting disc 7 to rotate, turning the pair of worn disc cutters 8 upward away from the cutting station. At the same time, the other pair of disc cutters 8, which has been pre-ground at the grinding and cleaning component 6 and is in a standby state, is switched to the lower cutting station to achieve uninterrupted cutting. The worn disc cutter 8, which is switched to the grinding and cleaning station, is simultaneously ground and cleaned by the grinding and cleaning component 6, thus forming a closed loop of "cutting - switching - grinding - standby - re-cutting", which effectively solves the production problem of rapid passivation of disc cutter 8 and frequent machine stoppages to replace cutters due to the high hardness of ferrous metal smelting rolled products. S4. Cooling, cleaning, and forced chip collection during the cutting process: When the paired disc cutters 8 are cutting, the miniature compressor 1008 on the mounting sleeve 1005 is activated, continuously blowing air towards the disc cutter 8 through the internal air outlet 1006 to cool and clean the blades; simultaneously, the downward-facing air outlet 1007 blows away the cutting position and the generated ferrous metal chips, blowing the high-temperature, sharp chips into the chip collection port 102 on the cutting groove 101. The chip collection box 3 below the chip collection port 102 adopts a negative pressure structure to powerfully suck up the falling chips, preventing chips from splashing and scratching the surface of the rolled product or polluting the environment. Due to the high hardness and temperature of ferrous metal chips, the combination of air cooling and negative pressure collection can significantly reduce the thermal wear of the disc cutter 8 and keep the cutting area clean. S5. Precise Grinding and Cleaning of the Disc Blade and Prevention of Debris Overflow: When the worn disc blade 8 rotates with the cutting disc 7 to the position corresponding to the grinding and cleaning groove 603 in the grinding and cleaning assembly 6, the telescopic rod 1004 in the adjusting assembly 10 retracts, and the lifting block 1003 moves upward, accurately sending the disc blade 8 into the grinding and cleaning groove 603. The retractable grinding head 605 in the grinding and cleaning groove 603 contacts the blade from both sides of the disc blade 8 for contour grinding, restoring its sharpness; at the same time, the air pump 607 sucks the grinding debris into the slag collection cylinder 602 through the exhaust head 604 set along the arc-shaped groove wall, and stores it after being filtered by the filter element 606. During this process, the exhaust head 1006 continues to send air to the disc blade 8 for cooling, and the upward-facing exhaust head 2 1007 sends air to the opening of the grinding and cleaning groove 603, forming an air curtain to prevent grinding debris from overflowing. After grinding, the disc cutter 8 exits the grinding and cleaning tank 603 and enters the standby station, awaiting the next switch to the cutting station. This process ensures that each pair of disc cutters 8 is sharp, clean, and cooled before being put back into cutting, meeting the stringent requirements for tool durability in ferrous metal smelting and rolling products; S6. Multi-station cycle and overall efficiency improvement in continuous cutting: During long-term continuous operation, the cutting disc 7 rotates periodically according to a preset program or real-time monitoring of the tool status, sequentially changing each pair of disc cutters 8 from the cutting position to the grinding and cleaning position, and replacing the ground disc cutters 8 with the cutting position. Simultaneously, the grinding and cleaning assembly 6 can move horizontally along the moving track 5, coordinating with the horizontal movement of the cutting disc 7, ensuring precise alignment of each pair of disc cutters 8 with the grinding and cleaning groove 603 even when the cutting width and position change. The positioning and moving assembly 4 continuously stabilizes the rolled product from multiple directions and controls the feed speed. Through these steps, the four stages of cutting, station switching, grinding and cleaning, and cooling and chip removal are highly synchronized and do not interfere with each other, achieving efficient, high-precision, and low-tool-wear continuous cutting processing of ferrous metal smelting rolled products.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
