Description

Technical Field

[0001] This invention relates to the field of steel plate cutting and processing technology, specifically to a high-efficiency steel plate cutting device and its control method. Background Technology

[0002] With the increasing market demand for personalized products, steel plate cutting can be customized according to customers' special requirements to produce unique products. In the manufacturing of some high-end equipment and precision instruments, there are often complex structures and high precision requirements. Steel plate cutting can realize these complex designs. The cut steel plate parts are easier to assemble and weld, which can improve production efficiency and overall product quality. For example, aerospace components require precisely cut steel plates to meet their requirements for lightweighting and high strength. In short, steel plate cutting is an indispensable and important link in modern industrial production. It provides steel plate materials that meet the needs of various fields and promotes industrial development and progress.

[0003] Based on the above, it should be noted that during the traditional steel plate cutting process, the processing environment and equipment can affect the uneven heat distribution or cutting stress, which may cause deformation of the steel plate. This is a serious problem for steel plates that need to maintain flatness and dimensional accuracy. At the same time, the heat generated during the cutting process may cause changes in the microstructure and properties of the steel plate near the cut edge, forming a heat-affected zone. This may reduce the strength, toughness, and other properties of the steel plate, and the heat-affected zone may exhibit increased hardness and brittleness.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an efficient steel plate cutting device and its control method. By preheating the steel plate cutting area during the conveying process, the temperature of the steel plate cutting area is made closer to the frictional heat generated during cutting, which effectively avoids the deformation of the steel plate caused by sudden high temperature and uneven heat distribution during cutting.

[0006] By temporarily covering and protecting the high-temperature accumulation area after the steel plate is cut, and providing a secondary high-temperature airflow to flush it and assist in the slow cooling of the high temperature, the changes in the strength and toughness of the steel plate material caused by the sudden drop in heat accumulation are effectively avoided. At the same time, by combining the preheating of the steel plate and the buffer cooling after cutting, the stress existing in the local deformation of the steel plate before and after cutting is effectively removed, thus solving the problem.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

An inner push cylinder is provided on the inner wall of both sides of the conveyor frame, and a follower plate is provided between the inner push cylinders. A heater is provided on the top of the follower plate, and an active cylinder is provided at the bottom of the outer side of the conveyor frame.

[0011] Furthermore, the supporting keel is surrounded by a sealing plate, and an air suction frame is provided on the inner top wall of the sealing plate. Multiple discharge ports are provided on the bottom of one side of the sealing plate, and an air pump is provided at the bottom corner of the other side of the supporting keel. A drive base is slidably provided on the central frame of the supporting keel, and a lifting cylinder connected to the cutting motor is provided through the center of the drive base. The cutting blade is installed on the output end of the cutting motor.

[0012] Furthermore, the limiting pressure frame is provided with lifting cylinder frames on both sides connected to the active cylinder, the limiting pressure frame is provided with an adjusting arm connected to the pressure roller at the top, the limiting pressure frame is provided with a heater at the center of the inner top wall, and the heater is provided with extrusion plates at both ends, and the extrusion plate is provided with a pressing cylinder connected to the limiting pressure frame at the top.

[0013] Furthermore, the reheating pusher is provided with lifting cylinder frames on both sides, which are connected to the active cylinder. Multiple sets of guide plates are provided at the center of the inner top wall of the reheating pusher. An air jet is provided on the inner wall of the reheating pusher at one end of the guide plate. Movable sealing plates are embedded on the inner top walls at both ends of the reheating pusher. A limiting cylinder connected to the movable sealing plate is provided at the top of the reheating pusher.

[0014] Furthermore, the end face of the limiting bracket is provided with a secondary bracket with the same structure, the bottom sides of the limiting bracket are provided with side feet connected to the central cylinder, the upper part of the limiting bracket is provided with a movable plate, and the top of the limiting bracket is provided with a lifting cylinder connected to the movable plate.

[0015] Furthermore, the bottom sides of the temperature-locking cylinder are provided with slides connected to the side cylinders, the end face of the temperature-locking cylinder away from the limiting bracket is provided with an end plate, and the bottom of the end plate is provided with a hanging curtain. Multiple sets of partition plates are provided on the inner top wall of the temperature-locking cylinder, and ventilation arc frames are provided on the surfaces of the partition plates and the end plates.

[0016] A control method for an efficient steel plate cutting device includes the following steps:

[0017] S1: The connecting bracket and the sub-frame are connected to the external production line conveying equipment respectively. The steel plate to be processed is conveyed by the external production conveying equipment to the conveying frame on the connecting bracket.

[0018] S2: The active cylinder on the connecting bracket drives the limiting pressure frame to move closer to the steel through the lifting cylinder frame one. The lifting cylinder frame one drives the entire limiting pressure frame to slide down until the limiting pressure frame is attached to the upper surface of the steel. The pressing cylinder drives the extrusion plate to slide down, further limiting the steel plate between the limiting pressure frame and the conveying roller. The heater two preheats the top of the area to be cut of the steel plate.

[0019] The inner push cylinder on the connecting bracket drives the follower plate and the limit pressure frame to move synchronously, and the heater on the follower plate preheats the bottom of the steel plate to be cut.

[0020] S3: The lifting cylinder drives the movable plate to slide down, lifting the area of ​​the steel plate to be cut. The limiting pressure frame and the reheating push frame are driven by the active cylinders on the connecting bracket and the sub-frame, respectively. The pressing cylinder drives the extrusion plate to slide down and extrude one end of the steel plate. The limiting cylinder drives the movable sealing plate to slide down and extrude the other end of the steel plate.

[0021] S4: The lifting cylinder drives the cutting motor to slide upward axially until the cutting blade steadily contacts the steel plate. The driven base drives the cutting motor to slide axially along the frame of the supporting keel, causing the cutting blade to perform directional reciprocating cutting on the cutting area of ​​the steel plate. The air pump is connected to the suction frame, air nozzle and ventilation arc frame through pipelines. The suction frame creates a negative pressure suction environment in the area below the cutting blade.

[0022] S5: The limiting pressure frame and the reheating push frame simultaneously release the restriction on the steel plate. Accompanied by the synchronous operation of the pressure roller and the conveying roller, the cut steel plate is further moved and pushed towards one end of the reheating push frame. The limiting cylinder drives the movable sealing plate to slide down, covering the steel plate cutting area. The secondary high-temperature air drawn by the air jet frame guides the suction port and the suction frame to be injected between the guide plate and the secondary high-temperature airflow between the bottom of the steel plate and the conveying roller and the adapter bracket. Due to the obstruction of the adapter push frame, most of it flows back to the limiting bracket area. The adapter bracket is driven by the inner push cylinder on the sub-frame, and it moves axially synchronously with the reheating push frame.

[0023] S6: When the limiting pressure frame and the reheating push frame release their limiting pressure on the steel plate during cutting, the residual heat inside the limiting pressure frame dissipates and flows upward, while some of the high-temperature air generated during cutting flows upward simultaneously and gathers in the inner wall area at the top of the two sets of heat-locking cylinders. Affected by the partition plate, the gathered secondary high-temperature airflow flows towards both ends of the heat-locking cylinders step by step. Affected by the suction port and the nozzle, under the action of the air pump circulation, it is continuously sprayed by the air jet frame, forming a thermal cycle inside the heat-locking cylinders, reducing heat loss.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention preheats the steel plate cutting area during transport, causing the temperature of the cutting area to gradually approach the frictional heat generated during cutting. This effectively avoids deformation of the steel plate caused by sudden high temperatures and uneven heat distribution during cutting. Furthermore, it provides temporary protection to the high-temperature accumulation area after cutting and provides secondary high-temperature airflow to flush it and assist in slowing down the temperature, effectively preventing changes in the strength and toughness of the steel plate material caused by a sudden drop in heat accumulation. At the same time, the combination of preheating the steel plate and buffer cooling after cutting effectively removes the stress present in the local deformation of the steel plate before and after cutting.

[0026] 2. This invention achieves a comprehensive protection of the steel plate cutting area by using the structural linkage between the cutting mechanism, the connecting bracket, and the heat-locking hood. It also utilizes a temporary combination of a limiting pressure frame, a reheating push frame, a limiting bracket, and a secondary bracket to form multi-point limiting clamping at both ends of the steel plate cutting area, effectively preventing the negative impact of steel plate swaying on the cutting process. Simultaneously, it uses targeted negative pressure extraction to remove the accumulated high temperature in the cutting area, effectively preventing the formation of a heat-affected zone. Furthermore, it recovers and reuses the residual heat generated during cutting and preheating to maintain the internal temperature environment of the heat-locking hood and to provide pneumatic cooling to the cut steel plate area.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1: This example addresses the problem that during the cutting process of traditional steel plates, the uneven heat distribution or deformation caused by cutting stress due to the processing environment and equipment can lead to uneven heat distribution or deformation. This is a serious problem for steel plates that need to maintain flatness and dimensional accuracy. At the same time, the heat generated during the cutting process may cause changes in the microstructure and properties of the steel plate near the cutting edge, forming a heat-affected zone. This may reduce the strength, toughness, and other properties of the steel plate, and the heat-affected zone may exhibit increased hardness and brittleness.

[0040] Please see Figure 1 - Figure 9 As shown, this embodiment is a high-efficiency steel plate cutting device and its control method, including a connecting bracket 1, a sub-frame 101 arranged side by side on the end face of the connecting bracket 1, a cutting mechanism 3 arranged below the connecting bracket 1 and the sub-frame 101, the cutting mechanism 3 including a sealing plate 302 and a supporting keel 304, a cutting motor 308 and a cutting blade 307 arranged on the top of the supporting keel 304, a reheating pusher 7 arranged on the top of the sub-frame 101, a limiting pressure frame 6 arranged on the top of the connecting bracket 1, and a limiting bracket 5 arranged between the limiting pressure frame 6 and the reheating pusher 7. The connecting bracket 1 and the sub-frame 101 are respectively connected to the external production line conveying equipment. The steel plate to be processed is conveyed by the external production conveying equipment to the conveying frame 104 on the connecting bracket 1. The conveying frame 104 drives the steel plate to be smoothly conveyed to the limiting bracket 5 by the synchronous rotation of multiple sets of conveying rollers on its surface.

[0041] A conveyor frame 104 is provided above both the connecting bracket 1 and the sub-frame 101. A central cylinder 102 is symmetrically provided on both sides of the top of the end faces of the connecting bracket 1 and the sub-frame 101 that are close to each other. Side cylinders 103 are symmetrically provided on the outer side of the top of the connecting bracket 1 and the sub-frame 101. An inner push cylinder 105 is provided on the inner wall of both sides of the conveyor frame 104. A follower plate 106 is provided between the inner push cylinders 105. A heater 107 is provided on the top of the follower plate 106. An active cylinder 108 is provided on the bottom of the outer side of the conveyor frame 104. While the heater 107 heats the steel plate, the inner push cylinder 105 on the connecting bracket 1 drives the follower plate 106 to move synchronously with the limiting pressure frame 6. The heater 107 on the follower plate 106 preheats the bottom of the area to be cut on the steel plate in advance, so that the preheating temperature and the cutting friction temperature rise steadily, avoiding the formation of a heat-affected zone. At the same time, it avoids uneven heat distribution or deformation of the steel plate caused by cutting stress during cutting.

[0042] The supporting keel 304 is surrounded by a sealing plate 302. The top inner wall of the sealing plate 302 is equipped with an air suction frame 303. Multiple discharge ports 301 are provided on one bottom side of the sealing plate 302. An air pump 309 is provided at the bottom corner of the other side of the supporting keel 304. Under the influence of its own weight and the rotational inertia of the cutting blade 307, most of the sparks and debris generated by cutting fall into the sealing plate 302.

[0043] During the active cutting of the steel plate by the cutting blade 307, the air pump 309 is connected to the suction frame 303, the air nozzle 705 and the ventilation arc frame 205 through pipelines. The suction frame 303 creates a negative pressure suction environment in the area below the cutting blade 307, which causes the preheated residual hot air around the steel plate and the high temperature hot air generated by cutting to be drawn back and concentrated and transported to the ventilation arc frame 205.

[0044] A drive base 305 is slidably mounted on the middle frame of the supporting keel 304, and a lifting cylinder 306 connected to the cutting motor 308 is installed through the middle of the drive base 305. The cutting blade 307 is mounted on the top output end of the cutting motor 308. The lifting cylinder 306 drives the cutting motor 308 to slide axially upward until the cutting blade 307 steadily contacts the steel plate. The cutting motor 308 starts and drives the cutting blade 307 to rotate at high speed. Driven by the drive base 305, the cutting motor 308 slides axially along the frame of the supporting keel 304, causing the cutting blade 307 to perform directional reciprocating cutting on the cutting area of ​​the steel plate.

[0045] Example 2: This example is a high-efficiency steel plate cutting device and its control method, including a pressure roller 602 provided on the top of the limiting pressure frame 6, a heat lock cylinder cover 2 provided above the limiting pressure frame 6, a ventilation arc frame 205 provided on the inner wall of the heat lock cylinder cover 2, and an adapter bracket 706 provided at the bottom of the reheat push frame 7.

[0046] The limiting pressure frame 6 has lifting cylinder frames 604 connected to the active cylinder 108 on both sides. The top of the limiting pressure frame 6 has an adjusting arm 601 connected to the pressure roller 602. When it approaches the area of ​​the limiting bracket 5, the compression limit of the steel plate is released. The adjusting arm 601 drives the pressure roller 602 to deflect downward until it abuts against the top surface of the steel plate. The outside of the adjusting arm 601 is a micro motor connected to the pressure roller 602. The micro motor drives the pressure roller 602 to rotate. The pressure roller 602, together with the conveying roller, moves the steel plate smoothly until the preheated area to be cut is moved above the limiting bracket 5. The center of the inner top wall of the limiting pressure frame 6 has a heater 605. The two ends of the heater 605 have extrusion plates 606. The top of the extrusion plate 606 is equipped with a pressing cylinder 603 connected to the limiting pressure frame 6.

[0047] When the steel plate enters the heat-locking shroud 2 on the connecting bracket 1, the active cylinder 108 on the connecting bracket 1 drives the limiting pressure frame 6 to move closer to the steel through the lifting cylinder frame 604 until the steel moves on the conveying frame 104 and exposes the cutting area. The limiting pressure frame 6 moves above the cutting area of ​​the steel, and the lifting cylinder frame 604 drives the entire limiting pressure frame 6 to slide down until the limiting pressure frame 6 is attached to the upper surface of the steel. The pressing cylinder 603 drives the extrusion plate 606 to slide down, further limiting the steel plate between the limiting pressure frame 6 and the conveying roller, so that the heater 605 and the steel plate form a sealed space. The heater 605 preheats the top of the area to be cut of the steel plate.

[0048] The reheating pusher 7 has lifting cylinder frames 703 connected to the active cylinder 108 on both sides. Multiple sets of guide plates 704 are provided in the center of the inner top wall of the reheating pusher 7. A jet nozzle 705 is provided on the inner wall of the reheating pusher 7 at one end of the guide plate 704. Movable sealing plates 702 are embedded on the inner top walls at both ends of the reheating pusher 7. A limiting cylinder 701 connected to the movable sealing plate 702 is provided on the top of the reheating pusher 7.

[0049] The end face of the limiting bracket 5 is provided with a secondary bracket 503 of the same structure. Side feet 501 connected to the central cylinder 102 are provided at the bottom of both sides of the limiting bracket 5. A movable plate 502 is provided above the limiting bracket 5, and a lifting cylinder connected to the movable plate 502 is provided at the top of the limiting bracket 5. When the area of ​​the steel plate to be cut is above the limiting bracket 5, the lifting cylinder drives the movable plate 502 to slide upwards, lifting the area of ​​the steel plate to be cut. The limiting pressure frame 6 and the reheating push frame 7 are respectively supported by the connecting bracket 1 and... Driven by the active cylinder 108 on the sub-frame 101, the partial areas at the bottom of the lifting cylinder frame 1 604 and the lifting cylinder frame 2 703 are inserted into the slots on both sides of the limiting bracket 5, so as to realize the temporary splicing of the limiting pressure frame 6, the reheating push frame 7, the limiting bracket 5 and the sub-bracket 503. A certain gap is reserved between the limiting pressure frame 6 and the reheating push frame 7. The pressing cylinder 603 drives the extrusion plate 606 to slide down and extrude one end of the steel plate. The limiting cylinder 701 drives the movable sealing plate 702 to slide down and extrude the other end of the steel plate to limit it.

[0050] After the steel plate is cut and separated, the limiting pressure frame 6 and the reheating push frame 7 simultaneously release the restriction on the steel plate. Accompanied by the synchronous operation of the pressure roller 602 and the conveying roller, the cut steel plate is further moved and pushed towards one end of the reheating push frame 7.

[0051] As the steel plate cutting area enters the middle of the reheating pusher 7, the limiting cylinder 701 further drives the movable sealing plate 702 to slide down, covering the steel plate cutting area. The secondary high-temperature air drawn by the jet guide inlet and the suction frame 303 is injected between the guide plate 704, forming a flowing secondary high-temperature airflow between the guide plate 704 and the steel plate. The secondary high-temperature airflow experiences temperature loss due to the internal environment of the heat-locking shroud 2, as well as temperature loss during transport. Consequently, the temperature of the secondary high-temperature airflow gradually decreases with the pause of multiple sets of heaters and the duration of the cutting stoppage. The secondary high-temperature airflow is affected by the guide plate 704. The warm airflow passes through the steel plate cutting area and seeps along the cutting gap, causing the temperature of the steel plate cutting area to gradually decrease under the interference of the secondary high-temperature airflow. This provides a gradual temperature drop environment for the steel plate area that has just been cut, effectively avoiding the sudden temperature drop caused by direct exposure to the external environment and reducing the impact of material changes caused by temperature difference in the cutting area. The secondary high-temperature airflow that enters the bottom of the steel plate between the conveying roller and the adapter bracket 706 is blocked by the adapter pusher and most of it flows back to the area of ​​the limiting bracket 5. The adapter bracket 706 is driven by the inner push cylinder 105 on the sub-frame 101, and it moves axially synchronously with the reheating pusher 7.

[0052] The bottom of both sides of the heat-locking cylinder 2 is provided with a slide 201 connected to the side cylinder 103. The end face of the heat-locking cylinder 2 away from the limiting bracket 5 is provided with an end plate 202, and the bottom of the end plate 202 is provided with a hanging curtain 203. Multiple sets of partition plates 204 are provided on the inner top wall of the heat-locking cylinder 2. The surfaces of the partition plates 204 and the end plates 202 are provided with ventilation arc frames 205. The top of the ventilation arc frame 205 is a suction port, and the bottom of the ventilation arc frame 205 is a spray port. The spray port is used to guide the input hot air to be sprayed into the interior of the heat-locking cylinder 2 to maintain the internal temperature of the heat-locking cylinder 2. The suction port is used to absorb the high-temperature hot air collected at the top of the heat-locking cylinder 2.

[0053] When the limiting pressure frame 6 and the reheating push frame 7 release their limiting pressure on the steel plate during cutting, the residual heat inside the limiting pressure frame 6 dissipates and flows upward, while some of the high-temperature air generated during cutting flows upward simultaneously and gathers in the inner wall area of ​​the top of the two sets of heat-locking cylinder hoods 2. Affected by the partition plate 204, the gathered secondary high-temperature airflow flows towards both ends of the heat-locking cylinder hood 2 step by step. Affected by the suction port and the nozzle, under the cyclic extraction action of the air pump 309, it is continuously sprayed by the jet frame, forming a thermal cycle inside the heat-locking cylinder hood 2, reducing heat loss.

[0054] Combining Embodiment 1 and Embodiment 2, it can both promote the temperature of the steel plate cutting area to gradually approach the frictional heat generated during cutting, effectively avoiding the deformation of the steel plate caused by sudden high temperature and uneven heat distribution during cutting, and avoid the change in the strength and toughness of the steel plate material caused by sudden heat drop. Combined with the preheating of the steel plate in advance and the buffer cooling after cutting, the stress existing in the local deformation of the steel plate before and after cutting is effectively removed.

4. A control method for a high-efficiency steel plate cutting device, used in the high-efficiency steel plate cutting device according to any one of claims 1-3, characterized in that, Includes the following steps S1: The connecting bracket (1) and the sub-frame (101) are respectively connected to the external production line conveying equipment. The steel plate to be processed is conveyed by the external production conveying equipment to the conveying frame (104) on the connecting bracket (1); S2: The active cylinder (108) on the connecting bracket (1) drives the limiting pressure frame (6) to move closer to the steel through the lifting cylinder frame one (604). The lifting cylinder frame one (604) drives the overall limiting pressure frame (6) to slide down until the limiting pressure frame (6) is attached to the upper surface of the steel. The pressing cylinder (603) drives the extrusion plate (606) to slide down, further limiting the steel plate between the limiting pressure frame (6) and the conveying roller. The heater two (605) preheats the top of the steel plate to be cut in advance. The inner push cylinder (105) on the connecting bracket (1) drives the follower plate (106) and the limiting pressure frame (6) to move synchronously. The heater (107) on the follower plate (106) preheats the bottom of the steel plate to be cut. S3: The lifting cylinder drives the movable plate (502) to slide upward, lifting the area of ​​the steel plate to be cut. The limiting pressure frame (6) and the reheating push frame (7) are driven by the active cylinder (108) on the connecting bracket (1) and the sub-frame (101), respectively. The pressing cylinder (603) drives the extrusion plate (606) to slide down and extrude one end of the steel plate. The limiting cylinder (701) drives the movable sealing plate (702) to slide down and extrude the other end of the steel plate. S4: The lifting cylinder (306) drives the cutting motor (308) to slide axially upward until the cutting blade (307) steadily contacts the steel plate. The driven base (305) drives the cutting motor (308) to slide axially along the frame of the supporting keel (304), causing the cutting blade (307) to perform directional reciprocating cutting on the cutting area of ​​the steel plate. The air pump (309) is connected to the suction frame (303), the air nozzle (705) and the ventilation arc frame (205) through pipelines. The suction frame (303) forms a negative pressure suction environment in the area below the cutting blade (307). S5: The limiting pressure frame (6) and the reheating push frame (7) simultaneously release the restriction on the steel plate. With the pressure roller (602) and the conveying roller running synchronously, the cut steel plate is further moved and pushed towards one end of the reheating push frame (7). The limiting cylinder (701) drives the movable sealing plate (702) to slide down, covering the steel plate cutting area. The secondary high-temperature air drawn by the air jet guide port and the suction frame (303) is injected between the guide plate (704) and enters the secondary high-temperature airflow between the bottom of the steel plate and the conveying roller and the adapter bracket (706). Due to the obstruction of the adapter push frame, most of it flows back to the area of ​​the limiting bracket (5). The adapter bracket (706) is driven by the inner push cylinder (105) on the sub-frame (101), and it moves axially synchronously with the reheating push frame (7). S6: When the limiting pressure frame (6) and the reheating push frame (7) release the limiting pressure frame (6) to cut the steel plate, the residual heat inside the limiting pressure frame (6) overflows and flows upward, while the high-temperature air generated by the cutting flows upward synchronously and gathers in the inner wall area of ​​the top of the two sets of heat-locking cylinders (2). Affected by the partition plate (204), the gathered secondary high-temperature airflow flows to both ends of the heat-locking cylinder (2) step by step. Affected by the suction port and the nozzle, under the circulation and extraction action of the air pump (309), it is continuously sprayed by the jet frame, forming a thermal cycle inside the heat-locking cylinder (2) to reduce heat overflow loss.
