This solves the problem that the internal space size of existing processing devices is fixed, and the entire space needs to be heated during the furnace heating process, which affects the furnace heating efficiency due to the large space.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a heating device for processing alloy hammerheads, comprising a furnace body;

[0008] The top of the furnace body is connected to a flue pipe, and a lifting plate is installed inside the furnace body. The outer surface of the lifting plate is in contact with the inner wall of the furnace body and can slide up and down. The top of the lifting plate is connected to a metal corrugated pipe, and the side of the metal corrugated pipe away from the lifting plate is connected to the flue pipe. The top of the furnace body is provided with an adjustment structure, which can control the vertical lifting of the lifting plate.

[0009] In a preferred embodiment of this invention, the adjusting structure includes a connecting frame fixedly connected to the top of the furnace body. A bidirectional screw is movably connected inside the connecting frame via a bearing. Screw sleeves are threadedly connected to the left and right sides of the surface of the bidirectional screw. Slide rods are fixedly connected to the front and back sides of the screw sleeves. A crank is fitted onto the surface of the slide rod. The side of the crank away from the slide rod passes through the furnace body and extends to the top of the lifting plate. A movable block located inside the crank is fixedly connected to the surface of the lifting plate. The movable block and the crank are movably connected via a pin.

[0010] As a preferred embodiment of this utility model, guide rods are fixedly connected to the four corners of the bottom of the furnace inner wall. The top of the guide rods passes through the lifting plate and is fixedly connected to the top of the furnace inner wall. The guide rods are slidably connected to the lifting plate.

[0011] As a preferred embodiment of this utility model, a bracket is fixedly connected to the top of the furnace body, and furnace covers are movably connected to both sides of the front of the bracket via pins. The furnace covers can be opened and closed by swinging the pins on the surface of the bracket.

[0012] As a preferred embodiment of this invention, the surface of the furnace cover is designed to be hollow, and the end of the slide rod away from the screw sleeve extends into the interior of the furnace cover and is slidably connected to the furnace cover.

[0015] As a preferred embodiment of this utility model, a drive motor is fixedly connected to the left side of the connecting frame, and the output end of the drive motor passes through the connecting frame and is fixedly connected to the left end of the bidirectional screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model forms an adjustable heating space through the sliding cooperation between the lifting plate and the inner wall of the furnace. The actual heating area can be reduced according to the size of the workpiece, reducing the heat energy consumption of the ineffective space. The connection design between the flue and the metal corrugated pipe maintains the continuity of the exhaust channel when the lifting plate moves, ensuring stable discharge of combustion exhaust gas and avoiding pressure imbalance that affects heating efficiency.

[0018] 2. This utility model achieves synchronous and opposite motion of two sets of crank mechanisms through the threaded transmission of the bidirectional screw and the screw sleeve, converting the rotational motion into the vertical displacement of the lifting plate. It has high control precision and stable power transmission. The movable block is connected to the crank pin to form a four-bar linkage mechanism, which effectively disperses the gravity load of the lifting plate and reduces the wear of the transmission system.

[0019] 3. This utility model uses four corner guide rods to pass through the lifting plate to form a multi-point guiding structure, eliminating the risk of the lifting plate tilting, ensuring accurate vertical lifting trajectory, and the fixed connection between the guide rods and the furnace body enhances the overall structural rigidity.

[0020] 4. This utility model achieves rapid opening and closing of the swing-type furnace cover via a pin shaft, which is coordinated with the movement of the lifting plate. After spatial adjustment, the furnace body is automatically sealed. The support fixing point design optimizes the mechanical distribution to prevent structural deformation caused by the weight of the furnace cover.

[0021] 5. This utility model maintains airflow circulation when the perforated furnace cover is closed, avoiding local overheating and accelerating the entry of exhaust gas into the flue. The slide rod extends into the inside of the furnace cover to form a linkage control, so that the opening and closing action of the furnace cover is strictly synchronized with the height change of the lifting plate, thereby improving the degree of automation of operation.

[0022] 6. This utility model achieves rapid workpiece positioning through the sliding cooperation between the guide rail and the support plate, reducing manual adjustment time. When the support plate is external, the workpiece can be easily loaded and unloaded. When internal, it forms a closed heating cavity with the lifting plate, ensuring that the workpiece is in the optimal heat radiation area.

[0023] 7. This utility model converts the vertical movement of the lifting plate into the horizontal displacement of the bearing plate through the sliding contact between the inclined fork and the force rod, realizing the mechanical linkage of the workpiece entering and leaving the furnace. The inclined surface reduces the impact force at the moment of contact, protects the positioning accuracy of the workpiece, and eliminates the operational risks of manually pushing and pulling the bearing plate.

[0024] 8. This utility model achieves electric adjustment by driving a bidirectional screw with a transmission motor, accurately controlling the displacement of the lifting plate, adapting to the heating requirements of workpieces of different sizes.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 6 As shown, the present invention provides a heating device for processing alloy hammerheads, comprising a furnace body 1;

[0034] The top of the furnace body 1 is connected to a flue pipe 2. The interior of the furnace body 1 is equipped with a lifting plate 3. The outer surface of the lifting plate 3 is in contact with the inner wall of the furnace body 1 and can slide up and down. The top of the lifting plate 3 is connected to a metal corrugated pipe 4. The side of the metal corrugated pipe 4 away from the lifting plate 3 is connected to the flue pipe 2. The top of the furnace body 1 is equipped with an adjustment structure 5, which can control the vertical lifting of the lifting plate 3.

[0035] refer to Figure 3The adjusting structure 5 includes a connecting frame 6 fixedly connected to the top of the furnace body 1. A bidirectional screw 7 is movably connected to the inside of the connecting frame 6 via a bearing. Screw sleeves 8 are threadedly connected to the left and right sides of the surface of the bidirectional screw 7. Slide rods 9 are fixedly connected to the front and back of the screw sleeves 8. A crank 10 is sleeved on the surface of the slide rod 9. The side of the crank 10 away from the slide rod 9 passes through the furnace body 1 and extends to the top of the lifting plate 3. A movable block 11 located inside the crank 10 is fixedly connected to the surface of the lifting plate 3. The movable block 11 and the crank 10 are movably connected via a pin.

[0036] As a technical optimization of this utility model, the two sets of crank 10 mechanisms move synchronously in opposite directions through the threaded transmission of the bidirectional screw 7 and the screw sleeve 8, converting the rotational motion into the vertical displacement of the lifting plate 3. This results in high control precision and stable power transmission. The movable block 11 is connected to the pin shaft of the crank 10 to form a four-bar linkage mechanism, which effectively disperses the gravitational load of the lifting plate 3 and reduces the wear of the transmission system.

[0037] refer to Figure 3 Guide rods 12 are fixedly connected to the four corners of the bottom of the inner wall of the furnace body 1. The top of the guide rods 12 passes through the lifting plate 3 and is fixedly connected to the top of the inner wall of the furnace body 1. The guide rods 12 are slidably connected to the lifting plate 3.

[0038] As a technical optimization of this utility model, the four corner guide rods 12 pass through the lifting plate 3 to form a multi-point guiding structure, which eliminates the risk of tilting of the lifting plate 3 and ensures the accuracy of the vertical lifting trajectory. The fixed connection between the guide rods 12 and the furnace body 1 enhances the overall structural rigidity, and the sliding contact surface reduces the direct friction between the lifting plate 3 and the furnace wall, thus extending the service life of the equipment.

[0039] refer to Figure 2 A bracket 13 is fixedly connected to the top of the furnace body 1. Both sides of the front of the bracket 13 are movably connected to the furnace cover 14 through pins. The furnace cover 14 can be opened and closed by swinging the pins on the surface of the bracket 13.

[0040] As a technical optimization of this utility model, the swing-type furnace cover 14 is opened and closed quickly through the pin shaft, and forms a timing coordination with the movement of the lifting plate 3. After the space adjustment is completed, the furnace body 1 is automatically sealed. The design of the fixing point of the bracket 13 optimizes the mechanical distribution to prevent structural deformation caused by the weight of the furnace cover 14.

[0041] refer to Figure 2 The surface of the furnace cover 14 is designed to be hollow, and the end of the slide rod 9 away from the screw sleeve 8 extends into the interior of the furnace cover 14 and is slidably connected to the furnace cover 14.

[0042] As a technical optimization of this utility model, the hollow furnace cover 14 maintains airflow circulation when closed, avoids local overheating and accelerates the entry of exhaust gas into the flue pipe 2. The slide rod 9 extends into the interior of the furnace cover 14 to form a linkage control, so that the opening and closing action of the furnace cover 14 is strictly synchronized with the height change of the lifting plate 3, thereby improving the degree of automation of operation.

[0043] refer to Figure 1 The bottom of the inner wall of the furnace body 1 is fixedly connected to a guide rail 15, and the top of the guide rail 15 is slidably connected to a bearing plate 16, which is used to support the alloy hammerhead.

[0044] As a technical optimization of this utility model, the workpiece is quickly positioned by sliding the guide rail 15 and the support plate 16, reducing the time for manual adjustment. When the support plate 16 is external, the workpiece can be easily loaded and unloaded. When it is internal, it forms a closed heating cavity with the lifting plate 3, ensuring that the workpiece is in the optimal heat radiation area.

[0045] refer to Figure 5 Both sides of the bottom of the lifting plate 3 are fixedly connected with a fork 17. The bottom end of the fork 17 is set to be inclined forward. The surface of the bearing plate 16 is fixedly connected with a force rod 18 located inside the fork 17. The force rod 18 is slidably connected to the fork 17.

[0046] As a technical optimization of this utility model, the vertical movement of the lifting plate 3 is converted into the horizontal displacement of the bearing plate 16 by the sliding contact between the inclined fork 17 and the force rod 18, so as to realize the mechanical linkage of the workpiece entering and leaving the furnace body 1. The inclined surface reduces the impact force at the moment of contact, protects the positioning accuracy of the workpiece, and eliminates the operational risk of manually pushing and pulling the bearing plate 16.

[0047] refer to Figure 2 A drive motor 19 is fixedly connected to the left side of the connecting frame 6. The output end of the drive motor 19 passes through the connecting frame 6 and is fixedly connected to the left end of the bidirectional screw 7.

[0048] As a technical optimization of this utility model, the electric adjustment is achieved by driving the bidirectional screw 7 through the transmission motor 19, which precisely controls the displacement of the lifting plate 3 to adapt to the heating requirements of workpieces of different sizes. The integrated installation of the transmission motor 19 and the connecting frame 6 saves external space, and the output shaft is directly connected to the bidirectional screw 7 to ensure power transmission efficiency and avoid the energy loss problem common in belt drives.

[0049] The working principle and usage process of this utility model are as follows: The operator places the alloy hammerhead on the support plate 16. When the alloy hammerhead is in place, the transmission motor 19 is started to drive the bidirectional screw 7 to rotate, which drives the two side sleeves 8 to move towards the center. The slide rod 9 moves with the sleeves 8 to push the crank 10 mechanism. Through the linkage of the movable block 11, the lifting plate 3 moves vertically downward along the guide rod 12. The metal bellows 4 extends and retracts synchronously with the descent of the lifting plate 3 to maintain the connection with the smoke pipe 2. During the downward pressing of the lifting plate 3, its bottom fork 17 contacts the force rod 18 on the support plate 16, and pushes the support plate 16 through the inclined structure. 6. Slide along the guide rail 15 inwards, and the bearing plate 16 slides into the furnace body 1 through the bottom guide rail 15. At this time, the lifting plate 3 is inside the furnace body 1, completing the initial filling. During the movement of the screw sleeve 8, the end of the slide rod 9 is linked to the furnace cover 14, and the hollow furnace cover 14 is closed through the pin of the bracket 13. At this time, a customized heating space is formed inside the furnace by the lifting plate 3, the furnace body 1 and the furnace cover 14. The volume of the space is dynamically reduced according to the size of the workpiece, which significantly reduces the amount of air that needs to be heated. After the heating system is started, only the limited space below the lifting plate 3 is heated, thereby achieving the effect of improving heating efficiency.

[0050] In summary, the heating equipment for alloy hammerhead processing forms an adjustable heating space through the sliding fit between the lifting plate 3 and the inner wall of the furnace body 1. The actual heating area can be reduced according to the size of the workpiece, thereby reducing the heat energy consumption of the ineffective space. The connection design between the smoke pipe 2 and the metal corrugated pipe 4 maintains the continuity of the exhaust channel when the lifting plate 3 moves, ensuring stable discharge of combustion exhaust gas and avoiding pressure imbalance that affects heating efficiency.
