Description

Technical Field

[0001] This invention relates to the field of vacuum hot pressing sintering equipment control technology, specifically to a furnace start-up control method and system for a hot pressing oscillating furnace. Background Technology

[0002] A hot-pressing oscillation furnace is an advanced device that introduces mechanical oscillation to improve material properties based on traditional vacuum hot-pressing sintering. For example, Chinese patent document CN118794250A discloses a structurally optimized vacuum hot-pressing furnace. This device cleverly transmits the reaction force during pressurization directly to the foundation by setting a movable seat that is elastically connected to the furnace lid and rigidly supporting the movable seat on the mounting foundation using movable support components during the pressurization stage. This significantly reduces the load requirements and manufacturing costs of the furnace lid opening and closing drive device and improves the stability of the pressurization process.

[0003] However, when an oscillation function is integrated into this type of high-efficiency structure to form a hot-pressing oscillating furnace, its operation, especially the furnace start-up stage after the process is completed, becomes exceptionally complex and riskier. Furnace start-up is a high-risk stage requiring close operator intervention. Currently, furnace start-up operations based on the above structure largely rely on manual experience or simple sequential control, and the following control challenges urgently need to be addressed: The complex safety conditions lack systematic interlocking: Before furnace startup, the equipment system is in a state of multiple potential hazards. High temperatures may remain inside the furnace; the vacuum or protective atmosphere environment needs to be restored to atmospheric pressure; the hydraulic system providing power for oscillation and pressurization may retain residual pressure; and the oscillation device itself may not have completely stopped or locked. Existing control methods lack comprehensive and coordinated detection and rigid safety interlocking for temperature, various pressures (furnace gas pressure, hydraulic pressure), the status of the oscillation mechanism, and critical mechanical positions (such as whether support components have completely moved out of their movement path). If the furnace startup sequence is not initiated before all safety conditions are met, serious safety accidents such as high-temperature burns, pressure shocks, and equipment malfunctions are highly likely to occur.

[0004] Insufficient precision in the timing and coordination of multiple actuators: The furnace start-up process involves the precise coordination of several key actions, such as the removal of movable support components, the locking and stopping of the oscillation device, and the opening and starting of the furnace cover. Incorrect sequence or timing of these actions will lead to mechanical interference.

[0005] The special risks of insufficient consideration of the oscillation function: The operation of the oscillation device is the core feature of the hot-pressing oscillating furnace and also a significant risk point for furnace start-up safety. If the furnace start-up operation is performed before the oscillation has completely decayed and stopped or the mechanical lock is not in effect, the residual vibration may be transmitted to the entire frame structure, affecting the smoothness of the start-up. Existing control strategies generally neglect the confirmation of the oscillation stop state and the acquisition and interlocking of the locking mechanism's position signal.

[0006] Therefore, existing technologies lack a dedicated intelligent safety control system for the start-up process of hot-pressing oscillating furnaces based on flexible connections and movable support structures. There is an urgent need for a control method that can systematically integrate multi-source signals, achieve strict safety interlocks, precisely coordinate the sequence of actions of multiple mechanisms, and ensure a smooth process to protect personnel and equipment safety and maintain the integrity of the technological results. This invention is proposed to fill this technological gap. Summary of the Invention

[0007] To address the technical problems existing in the prior art, the present invention provides a furnace start-up control method and system for a hot-pressing oscillating furnace that can systematically integrate multi-source signals, achieve strict safety interlocking, and accurately coordinate the action sequence of multiple mechanisms.

[0008] A method for controlling the start-up of a hot-pressing oscillating furnace, the hot-pressing oscillating furnace comprising a furnace body, a furnace cover mounted on a movable base via an elastic connecting assembly, an opening / closing drive device for driving the movable base to open and close the furnace cover, a pressurizing drive device for applying static pressure and oscillation pressure to the material, and a support assembly movable between a supported position and a non-interference position, the method comprising the following steps: S1: Receive furnace start command; S2: Collect multiple status signals before furnace start-up. The status signals include at least the furnace temperature signal, the furnace gas pressure signal, the hydraulic system pressure signal, and the position status signal of the support component; wherein, the hydraulic system pressure signal is associated with the pressurization drive device. S3: Based on the multi-channel status signals collected in step S2, perform a safety interlocking logic judgment to determine whether the following safety conditions are met simultaneously: a. The furnace temperature is below the first safety threshold; b. The gas pressure inside the furnace is within the normal atmospheric pressure range; c. The hydraulic system pressure is lower than a second safety threshold, which is set as a safe pressure to ensure that the pressurizing drive device does not generate oscillations or high-pressure output; d. The support component is in the supported position; If any security condition is not met, the corresponding preprocessing operation is performed until all security conditions are met. S4: After all safety conditions are met, execute the furnace opening action sequence in a predetermined order. The furnace opening action sequence includes at least: controlling the hydraulic control system of the pressurizing drive device to switch to a non-oscillating depressurization or safe state; controlling the support assembly to move from the support position to the non-interference position; and controlling the opening and closing drive device to drive the moving seat and furnace cover to open the furnace body.

[0009] As a further improvement to the above technical solution: In step S3, the preprocessing operations performed for unmet security conditions include at least one of the following: If condition a is not met, then start or maintain the operation of the furnace cooling system; If condition b is not met, control the vacuum / atmosphere system to either charge the furnace body with gas or exhaust gas from the furnace body. If condition c is not met, the hydraulic system of the pressurization drive device is depressurized. If condition d is not met, then control the support component to move to the support position.

[0010] In step S4, controlling the hydraulic control system of the pressurizing drive device to switch to a non-oscillating depressurization or safety state specifically involves controlling the hydraulic directional valve to switch to the neutral or unloading position and maintaining it for a set time.

[0011] In step S4, before controlling the movement of the support assembly, the step of re-detecting and confirming that the hydraulic system pressure is lower than the second safety threshold is also included.

[0012] In step S4, after controlling the movement of the support component, a position verification step is also included: after confirming that the support component has completely reached the non-interference position, the furnace cover opening action is then performed.

[0013] In step S4, the step of controlling the opening and closing drive device to drive the moving seat and furnace cover to move adopts segmented speed control: in the initial stage, it runs at a first low speed, and after confirming that there is no risk of interference between the moving seat and the support component, it switches to a second high speed.

[0014] The method further includes step S5: during the execution of the furnace start-up sequence, if the furnace start-up command is canceled or an emergency stop signal is received, all current actions are immediately interrupted, and the opening and closing drive device is controlled to stop, while the hydraulic system of the pressurizing drive device is maintained or switched to the depressurization state.

[0015] A start-up control system for a hot-pressing oscillating furnace, used to implement the start-up control method described above, the start-up control system comprising: The signal acquisition unit is used to acquire at least the furnace temperature, furnace pressure, hydraulic system pressure associated with the pressurization drive device, and position status signals of the support components before the furnace is started. The drive control unit is electrically connected to the hydraulic control system of the pressurizing drive device, the drive mechanism of the support assembly, and the opening and closing drive device, respectively, and is used to output control commands. The main controller is communicatively connected to both the signal acquisition unit and the drive control unit. The main controller is configured as follows: Based on the multi-channel status signals uploaded by the signal acquisition unit, a safety interlock logic judgment is performed. The logic judgment is based on preset conditions corresponding to safety conditions a to d in step S3. Once the safety interlock logic is passed, the drive control unit issues furnace start-up commands in sequence. The furnace start-up commands include at least a first command to control the pressurization drive device to switch to a safe state, a second command to control the support component to move to the non-interference position, and a third command to control the opening and closing drive device to start and open the furnace body.

[0016] As a further improvement to the above technical solution: The main controller is further configured to: when performing the safety interlock logic judgment, if any condition is not met, generate and issue a corresponding preprocessing control command, the preprocessing control command including at least one of the following: controlling the furnace cooling system, vacuum / atmosphere system valves, the depressurization operation of the pressurization drive device, or the drive mechanism of the support component.

[0017] The main controller is further configured to: Before issuing the second command, read and confirm again that the hydraulic system pressure meets the safety requirements; After issuing the second command, the position status of the support component is continuously read, and the third command is only allowed to be issued after it is confirmed that the component has reached the non-interference position. When the third command is issued, the opening and closing drive device is first driven with the first low-speed control parameter. After confirming that there is no risk of interference between the moving seat and the support component, the control parameter is switched to the second high-speed control parameter. If an emergency stop signal or a furnace start-up command cancellation signal is received during the execution of the furnace start-up command sequence, all command outputs are immediately interrupted, and control commands are generated to stop the start-up and stop the hydraulic system of the pressurization drive device and depressurize the hydraulic system of the pressurization drive device.

[0018] The present invention has the following beneficial effects: The furnace start-up control method and system of the hot-pressing oscillating furnace of the present invention achieves systematic safety interlocking and eliminates potential safety hazards: by forcibly and collaboratively judging four core safety conditions—furnace temperature, gas pressure, hydraulic system pressure, and support component position—before executing the furnace start-up action, a rigid, multi-factor comprehensive safety interlocking mechanism is established. This fundamentally avoids starting the furnace at high temperature, under pressure, or in an improper mechanical position due to operator negligence or omission of a single inspection, effectively preventing serious safety accidents such as burns, pressure shocks, and mechanical collisions. The furnace start-up action sequence must follow the order of "hydraulic system depressurization → support..." The predetermined sequence of "component removal → furnace cover opening" ensures that obstacles (support components) on the furnace cover's movement path are cleared in advance, perfectly solving the equipment interference and collision problems caused by incorrect action sequence in the background technology and protecting the equipment structure. The complex multi-state judgment and action sequence are automatically executed by the controller and preset program, replacing the high dependence on human experience. This not only reduces the difficulty of operation and the rate of human error, but also ensures the consistency, standardization and repeatability of each furnace opening operation, improving production efficiency and equipment operation reliability.

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 3 As shown in this embodiment, the furnace start-up control method for a hot-pressing oscillating furnace includes a furnace body 1, a furnace cover 2 mounted on a movable seat 31 via an elastic connecting component 6, an opening / closing drive device 3 for driving the movable seat 31 to open and close the furnace cover 2, a pressurizing drive device 5 for applying static pressure and oscillation pressure to the material, and a support component 7 that can move between a supported position and a non-interference position. The furnace start-up control method includes the following steps: S1: Receive furnace start command; S2: Collect multiple status signals before furnace start-up. The status signals include at least the furnace temperature signal, furnace gas pressure signal, hydraulic system pressure signal, and the position status signal of the support component 7. Among them, the hydraulic system pressure signal is associated with the pressurization drive device 5. S3: Based on the multi-channel status signals collected in step S2, perform a safety interlocking logic judgment to determine whether the following safety conditions are met simultaneously: a. The furnace temperature is below the first safety threshold, which in this embodiment is T=40℃; b. The gas pressure inside the furnace is within the normal atmospheric pressure range; c. The hydraulic system pressure is lower than the second safety threshold. The second safety threshold is set to ensure that the pressurization drive device 5 does not generate oscillation or high pressure output. In this embodiment, the second safety threshold P = 1 ton. d. Support component 7 is in the support position; If any security condition is not met, the corresponding preprocessing operation is performed until all security conditions are met. S4: After all safety conditions are met, execute the furnace opening sequence in a predetermined order. The furnace opening sequence includes at least: controlling the hydraulic control system of the pressurization drive device 5 to switch to a non-oscillating depressurization or safe state; controlling the support assembly 7 to move from the support position to the non-interference position; and controlling the opening and closing drive device 3 to drive the moving seat 31 and the furnace cover 2 to open the furnace body 1.

[0026] The furnace start-up control method and system of the hot-pressing oscillating furnace of the present invention achieves systematic safety interlocking and eliminates potential safety hazards: by forcibly and collaboratively judging four core safety conditions—furnace temperature, gas pressure, hydraulic system pressure, and support component position—before executing the furnace start-up action, a rigid, multi-factor comprehensive safety interlocking mechanism is established. This fundamentally avoids starting the furnace at high temperature, under pressure, or in an improper mechanical position due to operator negligence or omission of a single inspection, effectively preventing serious safety accidents such as burns, pressure shocks, and mechanical collisions. The furnace start-up action sequence must follow the order of "hydraulic system depressurization → support..." The predetermined sequence of "component removal → furnace cover opening" ensures that obstacles (support components) on the furnace cover's movement path are cleared in advance, perfectly solving the equipment interference and collision problems caused by incorrect action sequence in the background technology and protecting the equipment structure. The complex multi-state judgment and action sequence are automatically executed by the controller and preset program, replacing the high dependence on human experience. This not only reduces the difficulty of operation and the rate of human error, but also ensures the consistency, standardization and repeatability of each furnace opening operation, improving production efficiency and equipment operation reliability.

[0027] In this embodiment, step S3, the preprocessing operation performed for unmet security conditions, includes at least one of the following: If condition a is not met, then start or maintain the operation of the furnace cooling system; If condition b is not met, control the vacuum / atmosphere system to either charge the furnace body with gas or exhaust gas from the furnace body. If condition c is not met, the hydraulic system of the pressurization drive device 5 is depressurized. If condition d is not met, control the support component 7 to move to the support position.

[0028] By setting specific and automated pre-processing operations for each unmet safety condition (such as automatic cooling, charging and venting to restore atmospheric pressure, hydraulic depressurization, and drive support component repositioning), the automatic identification and handling of abnormal states are achieved. This avoids the tedious process of manual intervention and waiting by operators, significantly shortens the preparation time from the end of the process to safe furnace opening, and further improves the automation level of the entire process.

[0029] In this embodiment, step S4, controlling the hydraulic control system of the pressurizing drive device 5 to switch to a non-oscillating depressurization or safe state specifically involves controlling the hydraulic directional valve to switch to the neutral or unloading position and maintaining it for a set time. Specifying the switching of the hydraulic system to a safe state as "controlling the hydraulic directional valve to switch to the neutral or unloading position and maintaining it for a set time" ensures that residual pressure in the hydraulic circuit is fully released and that any potential hydraulic oscillations are completely attenuated, thereby providing an absolutely stable and interference-free force environment for subsequent mechanical actions and guaranteeing the accuracy of the actions.

[0030] In this embodiment, step S4 includes a step of re-detecting and confirming that the hydraulic system pressure is below the second safety threshold before controlling the movement of the support component 7. Adding a secondary pressure confirmation step before the critical action (controlling the movement of the support component) constitutes a double check of the hydraulic safety status. This effectively prevents misjudgments caused by instantaneous errors in the pressure sensor, signal interference, or incomplete initial pressure relief, providing an additional safety layer for subsequent mechanical movement and enhancing the system's robustness.

[0031] In this embodiment, after controlling the movement of the support component 7 in step S4, a position verification step is also included: after confirming that the support component 7 has completely reached the non-interference position, the furnace cover opening action is then performed. The position verification step is added after the support component moves, requiring confirmation that it has "completely reached" the non-interference position before the cover is allowed to open. This feature completely eliminates the potential risk of motion interference due to the support component not moving in place (such as jamming or not reaching the end of the stroke), ensuring the absolute unobstructed opening path of the furnace cover and improving the effectiveness of equipment protection.

[0032] In this embodiment, step S4, which controls the opening and closing drive device 3 to drive the moving seat 31 and the furnace cover 2, adopts segmented speed control: initially, it runs at a first low speed; after confirming that there is no risk of interference between the moving seat 31 and the support component 7, it switches to a second high speed. Using segmented speed control (low speed first, then high speed) to drive the furnace cover opening allows the large-inertia moving seat and furnace cover to start smoothly, effectively reducing hydraulic shock and equipment vibration during initial movement; switching to high speed after confirming no interference in the low-speed segment balances operating efficiency, helps protect the equipment's mechanical structure, seals, and the already formed work inside the furnace, and extends the equipment's service life.

[0033] In this embodiment, the method further includes step S5: during the execution of the furnace start-up sequence, if the furnace start-up command is canceled or an emergency stop signal is received, all current actions are immediately interrupted, and the opening / closing drive device 3 is stopped. The hydraulic system of the pressurizing drive device 5 is maintained or switched to a depressurized state. The introduction of an immediate response mechanism to the cancellation of the furnace start-up command and the emergency stop signal enables the system to possess proactive safety protection capabilities. It can immediately stop any dangerous actions being performed under any sudden abnormality or emergency human intervention, and place the system in a safe state (stop moving, hydraulic depressurization), greatly improving safety in dealing with unexpected situations.

[0034] like Figure 4 As shown, an embodiment of the furnace start-up control system for a hot-pressing oscillating furnace of the present invention is used to implement the furnace start-up control method as described in claims 1 to 7. The furnace start-up control system includes: The signal acquisition unit is used to acquire at least the furnace temperature, furnace pressure, hydraulic system pressure associated with the pressurization drive device 5, and position status signals of the support component 7 before the furnace is started. The drive control unit is electrically connected to the hydraulic control system of the pressurization drive device 5, the drive mechanism of the support component 7, and the opening and closing drive device 3, respectively, and is used to output control commands. The main controller is communicatively connected to both the signal acquisition unit and the drive control unit. The main controller is configured as follows: Based on the multi-channel status signals uploaded by the signal acquisition unit, a safety interlock logic judgment is performed. The logic judgment is based on preset conditions corresponding to safety conditions a to d in step S3 of the furnace start-up control method embodiment. Once the safety interlock logic is passed, the drive control unit issues furnace start-up commands in sequence. The furnace start-up commands include at least a first command to control the pressurization drive device 5 to switch to a safe state, a second command to control the support component 7 to move to a non-interference position, and a third command to control the opening and closing drive device 3 to start and open the furnace body 1.

[0035] In this embodiment, the main controller is further configured to generate and issue corresponding pre-processing control commands when performing safety interlock logic judgments if any condition is not met. These pre-processing control commands include at least one of the following: controlling the furnace cooling system, vacuum / atmosphere system valves, depressurization operation of the pressurization drive device 5, or the drive mechanism of the support component 7. The system's main controller is configured to automatically generate various pre-processing control commands, enabling the furnace start-up control system to possess complete closed-loop control capabilities. It can not only detect anomalies but also automatically drive relevant actuators (such as the cooling system, valves, and cylinders) to make corrections, achieving full automation from state perception and decision-making to execution, thus reducing the burden on operators.

[0036] In this embodiment, the main controller is further configured as follows: Before issuing the second command, read and confirm again that the hydraulic system pressure meets the safety requirements; After issuing the second command, the position status of the support component 7 is continuously read, and the third command is only allowed to be issued after it is confirmed that it has reached the non-interference position. When the third command is issued, the opening and closing drive device 3 is first driven with the first low speed control parameter. After confirming that there is no risk of interference between the moving seat 31 and the support component 7, the control parameter is switched to the second high speed control parameter. If an emergency stop signal or a furnace start-up command cancellation signal is received during the execution of the furnace start-up command sequence, all command outputs are immediately interrupted, and control commands are generated to stop the opening / closing drive device 3 and depressurize the hydraulic system of the pressurizing drive device 5. The system's main controller integrates multiple advanced control logics such as secondary pressure confirmation, continuous position verification, segmented speed control, and emergency stop handling, making the furnace start-up control system a highly integrated and intelligent safety control core. It can proactively avoid risks, verify action results, optimize the motion process, and decisively handle emergencies, thereby comprehensively ensuring the safety, stability, and reliability of the furnace start-up process at the hardware system level.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
