Description

Technical Field

[0001] The present invention relates to the technical field of steel plate processing, and in particular to a production line and method for manufacturing hot-formed and quenched steel plates. Background Art

[0002] In the manufacturing industry, especially in the processing of steel plates, hot forming and quenching are critical production steps that significantly impact the final performance of the product. In many traditional production lines, manual or semi-automatic methods are often used to heat, form, and quench the steel plates. From steel plate loading, heating, forming, to quenching, a large amount of manual work is often required, which limits production efficiency and increases worker workload. Manual operations can also affect product consistency and quality due to human error. Furthermore, manual operations in high-temperature environments increase the risk of operator injury.

[0003] In addition, in order to improve production efficiency and speed up production rhythm, the existing technology often adopts a large number of transmission mechanisms to achieve precise control and coordinated operation of each link. As the number of transmission mechanisms increases, more space is required for layout and maintenance, which will limit the flexibility and scalability of the production area. In addition, as the number of transmission mechanisms increases, energy consumption also increases, thereby increasing the operating costs of the enterprise. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a production line and method for manufacturing hot-formed and quenched steel plates, which is used to solve the problems in the prior art of generally using manual or semi-automatic methods to heat, form and quench steel plates, resulting in limited production efficiency and low product quality.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0006] A production line for manufacturing hot-formed and quenched steel plates, comprising heating equipment, a forming machine and a quenching equipment arranged in sequence, wherein the heating equipment and the quenching equipment both comprise a feeding mechanism, a heating mechanism and a temperature control device; the feeding mechanism comprises a work frame, a workbench arranged on the work frame, and a plurality of feeding devices arranged on the workbench; the heating mechanism comprises a heating furnace, a plurality of heating devices arranged in the heating furnace, and a plurality of feeding windows opened on the heating furnace; the temperature control device comprises a temperature measuring hole opened on the heating furnace and located above the heating device, a temperature measuring device arranged above the temperature measuring hole, and a temperature control system connected to the temperature measuring device and the heating device.

[0007] To implement the above technical solution, the design of several feeding devices enables the production line to process multiple steel plates at the same time, and enables the robots to operate more smoothly in the production line, thereby improving production efficiency and reducing the idle time of the robots. During operation, the steel plates are placed in the heating furnace through the feeding device. The heating furnace is equipped with a heating device. The feeding window on the heating furnace allows the steel plates to enter and exit the heating furnace smoothly through the feeding device. The temperature measuring hole is located above the heating device. The temperature measuring device monitors the temperature of the steel plate in real time through the temperature measuring hole. The measured temperature data is transmitted to the temperature control system. The temperature control system adjusts the power output of the heating device according to the set heating temperature and the actual measured temperature, thereby accurately controlling the temperature of the steel plate during the heating process; the heated steel plate is sent to the forming machine for forming. The forming machine processes it into the required shape according to the purpose and requirements of the steel plate; the formed steel plate enters the quenching equipment for quenching treatment to improve its hardness and wear resistance. The quenched steel plate needs to be cooled and post-processed to ensure that its performance meets the final requirements. The shape of the feeding window in the heating equipment and quenching equipment is set according to the shape of the steel plate to be heated. The temperature control system can accurately control the heating temperature to ensure that each steel plate can obtain a consistent heat treatment effect, thereby improving the quality consistency of the product. The automated feeding mechanism reduces the chance of operators directly contacting high-temperature equipment and reduces the risk of safety accidents. The continuous production process reduces idle time and improves production efficiency.

[0009] To implement the above technical solution, the supporting device is driven by the driving device to perform lifting movements. When the steel plate needs to be fed into the heating furnace, the supporting device descends to the bottom of the feeding window to receive the steel plate. After the heating is completed, the supporting device rises to prepare to receive the processed steel plate; the transporting device moves in the horizontal direction under the synchronous drive of the driving device. When it is close to the heating device, the steel plate can be placed in the heating device in the heating furnace.

[0011] To implement the above technical solution, the lifting plate is perpendicular to the mounting plate, which is connected to the column via a drive assembly. When the drive assembly is activated, the lifting plate can rise or fall along the vertical direction of the column, thereby driving the lifting and lowering of the supporting device. When the lifting plate rises or falls, the supporting device also moves accordingly to accommodate the lifting or transfer of steel plates. The material transport device is installed in the roller conveyor and is responsible for moving along the inclined roller conveyor to deliver steel plates from the feeding window into the heating furnace or remove them from the heating furnace.

The top of the lifting rod is connected with a slide, which can slide on the material transport slide on the workbench to realize the horizontal transportation of the steel plate. The material transport components are symmetrically provided on both sides of the slide, which are responsible for carrying the steel plate and ensuring the stability of the steel plate during movement; a guard is provided above the slide, and the function of the guard is to protect the slide from interference or damage by external factors during operation. The design of the material transport slide and the lifting plate makes the entire material transport device more compact and optimizes the space utilization of the production line.

[0014] In one embodiment of the present invention, the material transport assembly includes a mounting seat, a horizontal slide arranged on the mounting seat, a vertical slide arranged on the horizontal slide, and an L-shaped connecting plate arranged on the vertical slide; a mounting groove is provided at the upper end of the connecting plate, a material transport rod is embedded in the mounting groove, a clamping block is provided above the material transport rod to press the material transport rod in the mounting groove, and a material transport groove for embedding a steel plate is provided on the upper part of the material transport rod.

[0015] To implement the above technical solution, the horizontal slide and the vertical slide can be adjusted independently or jointly to change the positional relationship between them, thereby adjusting the height of the material transport rod and the spacing between the two material transport rods to accommodate steel plates of different sizes. Since the material transport rod is fixed in the mounting groove by a clamping block, the material transport rod can be quickly inserted or removed, which is convenient for replacing the material transport rod of appropriate size according to production needs. A material transport groove is provided on the upper part of the material transport rod for embedding the steel plate to be processed to ensure that the steel plate will not fall off during the movement; the height and spacing of the two material transport rods in this application are adjustable, so that the production line can process steel plates of various sizes, thereby improving the versatility and adaptability of the production line.

[0016] In one embodiment of the present invention, the material supporting device includes material supporting rods symmetrically arranged on both sides of the lifting plate, a support plate detachably arranged on the upper end of the material supporting rods, and a support block detachably arranged on the support plate; a plurality of fastening holes are correspondingly opened on the material supporting rods and the lifting plate, and fastening pins for fastening the lifting plate and the material supporting rods together are passed through the fastening holes; a connecting block is provided between the two material supporting rods; and a limit plate that can abut against the support block is provided on the workbench.

[0017] To implement the above technical solution, a number of fastening holes are correspondingly opened on the supporting rod and the lifting plate, and fastening pins are passed through these fastening holes to fasten the lifting plate and the supporting rod together to ensure the stability of the structure; a connecting block is provided between the two supporting rods, which helps to improve the stability and load-bearing capacity of the entire supporting device; the supporting rod is detachably provided with a support plate and a support block, so the support plate and the support block are easy to replace to adapt to steel plates of different sizes.

[0018] In one embodiment of the present invention, the drive assembly includes a driving slide rail vertically arranged on the column, a driving slider slidably arranged on the driving slide rail, and the driving slider is provided with the mounting plate; the drive assembly also includes a nut arranged on the mounting plate, a screw rod passed through the nut, a driven pulley arranged at one end of the screw rod, and a motor arranged on the column, a driving pulley is provided on the output shaft of the motor, and a belt is provided between the driving pulley and the driven pulley; an upper photoelectric detection switch and a lower photoelectric detection switch connected to the motor are provided on the column, and a reflector for reflecting light emitted by the upper photoelectric detection switch or the lower photoelectric detection switch is provided on the mounting plate; when the reflector passes through the upper photoelectric detection switch and the lower photoelectric detection switch, it can control the start and stop of the motor to accurately control the height of the lifting plate.

[0019] To implement the above technical solution, the start and stop of the motor and the forward and reverse rotation of the screw rod are controlled by the rotation direction, thereby controlling the rise and fall of the lifting plate. An upper photoelectric detection switch and a lower photoelectric detection switch connected to the motor are provided on the column, and a reflector is provided on the mounting plate. When the reflector passes through the upper photoelectric detection switch or the lower photoelectric detection switch, the start and stop of the motor can be controlled, thereby achieving precise control of the height of the lifting plate. Through the cooperation of the photoelectric detection switch and the reflector, the lifting plate can be precisely controlled to reach the predetermined position, thereby improving the automation and accuracy of the production line.

[0020] In one embodiment of the present invention, the heating device includes an induction coil for generating an alternating magnetic field and heating the steel plate; a magnetic ring distributed around the periphery of the induction coil and used in conjunction with the induction coil to increase the magnetic field strength and change the magnetic field distribution; and a plurality of insulating blocks arranged between the induction coil and the heating furnace for isolating the induction coil and the heating furnace.

[0021] To implement the above technical solution, the induction coil is the core component of the heating device. When alternating current is passed through it, the induction coil generates an alternating magnetic field. When this alternating magnetic field passes through the steel plate, an induced current is generated in the steel plate. Due to the resistance of the steel plate, Joule heat is generated, causing the steel plate to heat up rapidly. The magnetic ring can focus and guide the magnetic field so that the magnetic field acts more concentratedly on the steel plate, thereby improving the heating efficiency. An insulating block is provided between the induction coil and the heating furnace to isolate the induction coil and the heating furnace to prevent short circuit or equipment damage caused by high temperature. At the same time, the heating furnace is also made of insulating and high-temperature resistant materials. In the heating equipment and quenching equipment, the shape of the induction coil is set according to the shape of the steel plate to ensure that the steel plate is located in the middle of the induction coil, thereby ensuring uniform heating of the steel plate. The induction heating method can achieve rapid heating, greatly shorten the heating time of the steel plate, and improve the efficiency of the production line. The use of the magnetic ring can improve the distribution of the magnetic field, making the steel plate heated more evenly, which helps to improve the quality of hot forming and quenching.

[0022] In one embodiment of the present invention, the temperature measuring device includes a mounting frame arranged on the workbench, a temperature measuring probe arranged on the mounting frame through an adjustment component, and a temperature display connected to the temperature measuring probe; the adjustment component includes a base arranged on the mounting frame, an adjustment rod movably arranged on the base and arranged horizontally, a first adjustment block hinged on the adjustment rod, and a second adjustment block hinged on the first adjustment block, and the temperature measuring probe is provided on the second adjustment block; the temperature control system includes an electromagnetic controller and a temperature controller, the electromagnetic controller is used to control the power output of the induction coil, and the temperature controller is connected to the temperature measuring probe, receives the actual temperature value fed back by the temperature measuring probe and compares it with a preset temperature value, thereby adjusting the power output of the electromagnetic controller.

[0023] To implement the above technical solution, the position and angle of the temperature probe can be flexibly adjusted by adjusting the components. The temperature probe measures the temperature of the steel plate and transmits the data to the temperature display. The temperature display shows the temperature of the steel plate in real time for the operator to monitor. If the actual temperature of the steel plate deviates from the preset value, the temperature controller adjusts the power output of the electromagnetic controller to adjust the alternating magnetic field strength generated by the induction coil, thereby controlling the heating temperature of the steel plate. Through real-time measurement and feedback adjustment, the temperature control system can accurately control the heating temperature of the steel plate to meet the temperature requirements during hot forming and quenching.

[0024] In one embodiment of the present invention, a method for manufacturing hot-formed and quenched steel plates is provided, comprising the following steps: (1) heating the steel plate by means of heating equipment; (2) placing the heated steel plate in a forming machine by means of a robot and processing it into a specific shape; (3) placing the formed steel plate in a quenching equipment by means of a robot for quenching; both steps (1) and (2) comprise the following steps: S1, the material transport rod is away from one side of the heating furnace, and the steel plate is placed on the material transport rod by the robot; S2, the motor drives the lifting plate to move downward, drives the support block to move downward, drives the material transport rod to pass through the material transport window and places the steel plate in the heating device; S3, the motor drives the lifting plate to move upward, drives the material transport rod to move out of the heating device, and at the same time the support block moves upward and lifts the heated steel plate; S4, the robot removes the heated steel plate, and the motor drives the lifting plate to move upward and moves the material transport rod further away from the heating furnace.

[0025] Implementing this technical solution, through the involvement of robots, fully automates the entire steel plate process, from heating to forming to quenching, reducing manual intervention and improving production efficiency. A motor-driven lift plate precisely controls the position of steel plates entering and exiting the furnace, ensuring accurate heating and improving product quality. The design of a single motor driving both the support and transport mechanisms simplifies the mechanical structure, reduces the number of mechanical components, and reduces mechanical failure rates and maintenance costs.

[0026] As described above, the production line and method for manufacturing hot-formed and quenched steel plates of the present invention have the following beneficial effects:

[0027] 1. The design of multiple feeding devices enables the production line to process multiple steel plates at the same time, improving production efficiency. The robot automatically completes the handling of steel plates, reducing the need for manual intervention and the labor intensity of operators. The continuous production process reduces idle time and improves production efficiency.

[0028] 2. The temperature control system can accurately control the heating temperature, ensuring that each steel plate can obtain consistent heat treatment effect, improving product quality and consistency; through real-time measurement and feedback adjustment, it ensures the temperature requirements of the steel plate during hot forming and quenching.

[0029] 3. The automated feeding mechanism reduces the chances of operators directly contacting high-temperature equipment and reduces the risk of safety accidents.

[0030] 4. The height and spacing of the two transport bars are adjustable, enabling the production line to process steel plates of various sizes, improving the versatility and adaptability of the production line.

[0031] 5. The design of using one motor to drive both the supporting device and the transporting device simplifies the mechanical structure, reduces the number of transmission mechanisms, and reduces mechanical failure rate and maintenance costs.

[0061] The heating device includes an induction coil 45 for generating an alternating magnetic field and heating the steel plate 8; a magnetic ring 46 distributed around the periphery of the induction coil 45 and used in conjunction with the induction coil 45 to increase the magnetic field strength and change the magnetic field distribution; and a plurality of insulating blocks 47 arranged between the induction coil 45 and the heating furnace 61 for isolating the induction coil 45 from the heating furnace 61.

[0062] The induction coil 45 is the core component of the heating device. When alternating current is applied, the induction coil 45 generates an alternating magnetic field. When this alternating magnetic field passes through the steel plate 8, an induced current is generated in the steel plate 8. Due to the resistance of the steel plate 8, Joule heat is generated, causing the steel plate 8 to heat rapidly. The magnetic ring 46 can focus and guide the magnetic field so that the magnetic field acts more concentratedly on the steel plate 8, improving the heating efficiency. The insulating block 47 is provided between the induction coil 45 and the heating furnace 61 to isolate the induction coil 45 and the heating furnace 61 to prevent short circuits or equipment damage caused by high temperature. At the same time, the heating furnace 61 is also made of insulating and high-temperature resistant materials. In the heating equipment 1 and the quenching equipment 3, the shape of the induction coil 45 is set according to the shape of the steel plate 8, ensuring that the steel plate 8 is located in the middle of the induction coil 45, ensuring uniform heating of the steel plate 8. The induction heating method can achieve rapid heating, greatly shorten the heating time of the steel plate 8, and improve the efficiency of the production line. The use of the magnetic ring 46 can improve the distribution of the magnetic field, making the steel plate 8 heated more uniformly, which helps to improve the quality of hot forming and quenching.

[0063] The temperature measuring device includes a mounting frame 48 arranged on the working frame 4, a temperature measuring probe 49 arranged on the mounting frame 48 through an adjusting component, and a temperature display 50 connected to the temperature measuring probe 49; the adjusting component includes a base 51 arranged on the mounting frame 48, an adjusting rod 52 movably arranged on the base 51 and arranged horizontally, a first adjusting block 53 hinged on the adjusting rod 52, and a second adjusting block 54 hinged on the first adjusting block 53, and the temperature measuring probe 49 is provided on the second adjusting block 54; the temperature control system includes an electromagnetic controller and a temperature controller, the electromagnetic controller is used to control the power output of the induction coil 45, and the temperature controller is connected to the temperature measuring probe 49, receives the actual temperature value fed back by the temperature measuring probe 49 and compares it with a preset temperature value, thereby adjusting the power output of the electromagnetic controller.

[0064] The position and angle of the temperature probe 49 can be flexibly adjusted by adjusting the assembly. The temperature probe 49 measures the temperature of the steel plate 8 and transmits the data to the temperature display 50. The temperature display 50 displays the temperature of the steel plate 8 in real time for the operator to monitor. If the actual temperature of the steel plate 8 deviates from the preset value, the temperature controller will adjust the power output of the electromagnetic controller to adjust the alternating magnetic field strength generated by the induction coil 45, thereby controlling the heating temperature of the steel plate 8. Through real-time measurement and feedback adjustment, the temperature control system can accurately control the heating temperature of the steel plate 8 to ensure the temperature requirements during the hot forming and quenching processes.

[0065] A method for manufacturing a hot-formed and quenched steel plate comprises the following steps: (1) heating a steel plate 8 by a heating device 1; (2) placing the heated steel plate 8 in a forming machine 2 by a robot and processing it into a specific shape; (3) placing the formed steel plate 8 in a quenching device 3 by a robot for quenching; said steps (1) and (2) both comprise the following steps: S1, a material transport rod 24 is away from one side of the heating furnace 61, and the steel plate 8 is placed on the material transport rod 24 by the robot; S 2. The motor 39 drives the lifting plate 11 to move downward, drives the support block 29 to move downward, drives the material transport rod 24 to pass through the material transport window and places the steel plate 8 in the heating device; S3, the motor 39 drives the lifting plate 11 to move upward, drives the material transport rod 24 to move out of the heating device, and at the same time the support block 29 moves upward and lifts the heated steel plate 8; S4, the robot removes the heated steel plate 8, and the motor 39 drives the lifting plate 11 to move upward and makes the material transport rod 24 further away from the heating furnace 61.

[0066] The robot's involvement automates the entire process of heating, forming, and quenching the steel plate 8, reducing manual intervention and improving production efficiency. Motor 39 drives the lifting plate 11 to precisely control the position of the steel plate 8 in and out of the furnace, ensuring accurate heating and improving product quality. The design of a single motor 39 driving both the support and transport mechanisms simplifies the mechanical structure, reduces the number of mechanical components, and reduces mechanical failure rates and maintenance costs.
