Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of annealing furnace, and particularly relates to an annealing furnace for valve machining. BACKGROUND

[0002] Valves are key equipment in fluid control systems and are widely used in petroleum, chemical industry, papermaking, food, pharmaceutical and other industries. Annealing furnace is a kind of metal heat treatment process that places metal parts in different annealing furnaces and slowly heats them to a certain temperature, keeps them for a period of time, and then cools them at a suitable speed. With the continuous progress of industrial technology, the requirements for the quality, performance and corrosion resistance, high temperature resistance and other characteristics of valves are also increasing. Therefore, it is particularly important to use advanced heat treatment technology to improve the comprehensive performance of valves during valve machining. Through annealing treatment, the material organization of the valve is more uniform, the density increases, the strength and hardness increase, and the corrosion resistance is also improved.

[0003] The patent with publication number CN219670576U discloses an annealing furnace and relates to the technical field of metal production equipment. It comprises a furnace body, a furnace opening is formed on one side of the furnace body, a furnace door plate is arranged at the furnace opening, a heat preservation lining is arranged on the inner wall of the furnace body, a plug-in strip is arranged on the side of the heat preservation lining facing the inner wall of the furnace body, the length direction of the plug-in strip is consistent with the depth direction of the furnace body, a plug-in groove is formed in the inner wall of the furnace body for the plug-in strip, and a locking assembly is arranged on one side of the furnace body close to the furnace door plate, which is used to fix the heat preservation lining and the inner wall of the furnace body.

[0004] The above-mentioned patent sets the furnace door plate as a hinged structure and fixes the furnace door plate by setting a locking assembly. Although it can achieve the fixing effect of the furnace door plate, it is still necessary to disassemble two locking parts when disassembling, which is relatively cumbersome. Moreover, the fixed structure relying on the locking part is prone to fail to continue fixing after wear, resulting in high replacement cost and the need for improvement. UTILITY MODEL CONTENT

[0005] The purpose of the present application is to provide an annealing furnace for valve machining that can solve the above-mentioned problems.

[0006] The purpose of the present application is to provide an annealing furnace for valve machining, which comprises:

[0007] A furnace body, one side of which is provided with a furnace opening;

[0008] A door frame is arranged at the furnace opening, and a through slot is arranged on the surface of the door frame;

[0009] A furnace door plate is arranged on the door frame and used to seal the furnace opening;

[0010] A driving structure is arranged on both sides of the door frame and connected with the furnace door plate;

[0011] The furnace door plate passes through the through slot and can slide up and down along the door frame under the action of the driving structure.

[0012] The annealing furnace of the present application can make the furnace door plate slide up and down along the door frame through the driving structure, simplifying the opening and closing process of the furnace door. Users no longer need to spend time and effort to disassemble and install the locking parts, but only need to easily complete the opening and closing of the furnace door through the driving structure, improving the operation efficiency. The furnace door plate is tightly matched with the door frame through sliding, ensuring the sealing of the furnace port. At the same time, the design of the driving structure can ensure that the furnace door plate is firmly fixed on the door frame when it is closed, avoiding the problem of fixing failure caused by the wear of the locking parts, not only improving the stability of the furnace door, but also prolonging the service life of the equipment.

[0013] In addition, the annealing furnace of the present application avoids the use of easily-worn locking parts, thus reducing the frequency of replacement due to damage to the locking parts, not only reducing the maintenance cost of the equipment, but also reducing the impact on production caused by downtime maintenance. The stable fixation and convenient operation of the furnace door plate not only improve the production efficiency, but also enhance the safety of the equipment. In the closed state of the furnace door, the tight fit between the furnace door plate and the door frame can prevent high-temperature gas or sparks from leaking, thereby ensuring the safety of the operators.

[0014] Further, the driving structure comprises:

[0015] a driver arranged on both sides of the door frame;

[0016] a connecting assembly, one end of which is connected with the output end of the driver, and the other end of which is connected with the top of the furnace door plate;

[0017] a buffer assembly arranged on one side of the driver, one end of which is connected with the furnace body, and the other end of which is connected with the connecting assembly;

[0018] The driver is a pneumatic cylinder, and the driver drives the furnace door plate to move up and down through the connecting assembly.

[0019] The driver adopts a pneumatic cylinder design, which has the advantages of fast response speed, large driving force, and accurate control. The pneumatic cylinder can push or pull the connecting assembly by receiving control signals, thereby driving the furnace door plate to slide up and down along the door frame, not only improving the efficiency and stability of the opening and closing of the furnace door, but also making the entire operation process more automated and intelligent. The connecting assembly acts as a bridge between the pneumatic cylinder and the furnace door plate, playing a role in transmitting driving force and keeping the furnace door plate stable sliding. It can bear the weight of the furnace door plate and the thrust generated by the pneumatic cylinder, ensuring that the furnace door does not shake or deviate from the track during sliding. The setting of the buffer assembly can absorb and disperse impact force, reduce the collision and wear between the furnace door plate and the door frame, not only prolonging the service life of the equipment, but also improving the stability and safety of the operation.

[0020] By introducing the driving device, the connecting assembly and the buffering assembly, the driving structure of the annealing furnace for valve machining of the present application realizes precise, stable and efficient driving of the furnace door plate, which not only improves the practicality and durability of the equipment, but also reduces the maintenance cost, enhances the safety and has strong adaptability.

[0021] Further, the connecting assembly comprises:

[0022] The limiting plate is arranged on the top of the furnace door plate.

[0023] The connecting vertical plate is arranged on the top of the limiting plate.

[0024] The area of the limiting plate is larger than the area of the through slot, and the other end of the connecting vertical plate is connected with the output end of the driving device.

[0025] The limiting plate is arranged on the top of the furnace door plate, which mainly limits the sliding range of the furnace door plate and ensures that the furnace door does not move excessively or deviate from the track during opening and closing. Since the area of the limiting plate is larger than the area of the through slot, it can effectively prevent the furnace door plate from falling out of the through slot of the door frame during sliding, thereby enhancing the stability and safety of the equipment. The connecting vertical plate is arranged vertically on the top of the limiting plate and serves as a bridge between the output end of the driving device and the furnace door plate.

[0026] By skillfully combining the limiting plate and the connecting vertical plate, the connecting assembly not only realizes stable connection and driving of the furnace door plate, but also ensures the safety and reliability of the furnace door during opening and closing, thereby improving the practicality and durability of the equipment.

[0027] Further, the buffering assembly comprises:

[0028] The cylinder is connected with the connecting vertical plate at the top.

[0029] The piston rod is connected with the cylinder at one end and is arranged on the door frame at the other end.

[0030] The furnace body is further provided with a movable frame for the up-and-down movement of the cylinder.

[0031] The cylinder serves as the main part of the buffering assembly and is connected with the connecting vertical plate at the top, which ensures that the buffering assembly can intervene and absorb the impact force in time when the furnace door plate slides up and down under the action of the driving device, thereby reducing the direct collision between the furnace door plate and the door frame and prolonging the service life of the equipment. One end of the piston rod is tightly connected with the cylinder, and the other end is firmly installed on the movable frame of the furnace body. When the furnace door plate moves, the piston rod will perform extension and contraction movement in the cylinder, thereby effectively absorbing and dispersing the impact force. The movable frame is arranged on the door frame to provide the necessary space and support for the up-and-down movement of the cylinder.

[0032] By skillfully combining the barrel, the piston rod and the movable frame together, the buffer assembly realizes effective buffering during the sliding process of the furnace door plate. When the furnace door plate moves quickly and approaches the door frame, the buffer assembly can timely intervene and slow down the speed of the furnace door plate, thereby avoiding noise, vibration and wear caused by direct collision, improving the stability and safety of the equipment, and reducing the maintenance cost and use noise.

[0033] Further, the movable frame is provided with a spring, the spring is sleeved outside the piston rod, and two ends of the spring are connected with the bottom of the movable frame and the barrel respectively.

[0034] When the furnace door plate moves up and down, the spring will be elastically deformed by the movement of the barrel, thereby effectively slowing down the speed and impact force of the furnace door plate, protecting the furnace door plate and the door frame from damage, and reducing noise and vibration during operation. At the same time, the rigidity and stability of the piston rod also ensure the controllability and reliability of the spring during deformation.

[0035] Further, the edge of the top of the through groove is further provided with a sealing strip.

[0036] The sealing strip is closely attached to the edge of the top of the through groove, improving the sealing performance after the furnace door plate is closed. The sealing strip is made of high-temperature-resistant and wear-resistant material, which can withstand the high-temperature environment in the furnace and the friction caused by frequent opening and closing of the furnace door plate. At the same time, the sealing strip makes the furnace door plate more closely attached to the door frame when closing, reducing the generation of noise and vibration.

[0037] The beneficial effects of the present application are:

[0038] 1. The furnace door plate can slide up and down along the door frame through the driving structure, simplifying the opening and closing process of the furnace door. Users no longer need to disassemble and install the locking piece, but only need to easily complete the opening and closing of the furnace door through the driving structure, improving the operation efficiency;

[0039] 2. The design of the driving structure can ensure that the furnace door plate is firmly fixed on the door frame when it is closed, avoiding the problem of fixing failure caused by wear of the locking piece, improving the stability of the furnace door, and prolonging the service life of the equipment;

[0040] 3. The annealing furnace of the present application avoids using the easily-worn locking piece, thereby reducing the frequency of replacement due to damage of the locking piece, reducing the maintenance cost of the equipment, and reducing the impact on production caused by downtime maintenance.
