Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of titanium alloy heat treatment equipment, specifically relating to an opening and closing device for the discharge port of a vertical titanium alloy phase change point heat treatment furnace. Background Technology
[0002] Titanium alloys are widely used in aerospace, medical devices, and chemical equipment due to their excellent mechanical properties and corrosion resistance. The phase transformation point of titanium alloys is the critical temperature at which their internal microstructure changes during heating, and this phase transformation process has a significant impact on the material's mechanical and processing properties. Therefore, accurately controlling the phase transformation point of titanium alloys is crucial for improving their performance.
[0003] Vertical titanium alloy phase change point furnaces are key equipment for achieving phase change point heat treatment of titanium alloys. Their structure typically includes a heating system, a tubular furnace body, a control system, a cooling water tank, an insulation layer, a support frame, and inlet / outlet opening and closing devices. Currently, most companies use open-type atmospheric phase change point furnaces for phase change point heat treatment. This type of furnace requires good sealing, no temperature leakage, and stable and reliable operation during operation.
[0004] However, existing vertical titanium alloy phase change furnace discharge port opening and closing devices primarily use rotary cylinders to drive baffles for opening and closing operations. Due to structural limitations, the baffles driven by the rotary cylinders are prone to deformation at high temperatures. Gaps appear between the deformed baffles and the furnace opening, causing temperature runoff during furnace operation. Furthermore, when material needs to be discharged, the deformed baffles may rub against the furnace bottom shell and become jammed, preventing the discharge port from opening properly and the material from falling automatically. This jams the material between the discharge port and the baffle, delaying the material's discharge time and preventing it from meeting process requirements. It may also lead to material spoilage, severely impacting production efficiency and product quality. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a vertical titanium alloy phase change point heat treatment furnace discharge port opening and closing device. This opening and closing device can prevent the baffle from deforming under high temperature conditions, realize the effective closure or safe opening of the discharge port, thereby ensuring the reliability of the material heat treatment process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] This utility model proposes a discharge port opening and closing device for a vertical titanium alloy phase change point heat treatment furnace, including a baffle adapted to the discharge port of the phase change point furnace, and a driving component for controlling the rotation and lifting of the baffle. The output end of the driving component is fixedly connected to the baffle, and the fixed end is fixedly connected to the column on the phase change point furnace.
[0008] Furthermore, the drive component is connected to the baffle via a support member.
[0009] Furthermore, the support member includes a rotating arm and a supporting arm. One end of the rotating arm is fixedly connected to the output end of the driving component, and the other end is fixedly connected to one end of the supporting arm. The other end of the supporting arm is fixedly connected to a baffle.
[0010] Furthermore, the support arm is threadedly connected to the baffle, and the baffle is fixed to the support arm by fasteners.
[0011] Furthermore, the angle between the rotating arm and the support arm is 90 degrees.
[0012] Furthermore, the fixed end of the driving component is fixedly connected to the column via a fixed bracket.
[0013] Furthermore, the driving component is a rotary downward pressing cylinder.
[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:
[0015] (1) The opening and closing device proposed in this utility model connects the baffle to the output end of the driving component. When the discharge port needs to be opened, the driving component first drives the baffle to descend vertically a certain distance, and then drives the baffle to rotate horizontally a certain angle, without affecting the falling of the material. When the discharge port needs to be closed, the driving component first drives the baffle to rotate horizontally, and then drives the baffle to rise vertically to contact the discharge port, sealing the discharge port. In the process of opening and closing the discharge port, the opening and closing device of this utility model can avoid the baffle from deforming in a high-temperature environment, and can achieve effective closure and safe opening of the discharge port. It can ensure that the phase change furnace will not run out of temperature during operation, and can also ensure that the material is discharged smoothly, so that the time after the material is discharged meets the process requirements, thereby improving the production efficiency and quality of the product.
[0016] (2) Different phase change furnaces may have different specifications. This utility model connects the baffle and the support arm by thread. In this way, the height of the baffle can be adjusted according to the distance between the discharge port of the phase change furnace and the ground, thereby ensuring the effective closure of the discharge port of the phase change furnace by the baffle.

[0023] Example
[0024] See Figure 1 A vertical titanium alloy phase change point heat treatment furnace discharge port opening and closing device includes a baffle 2 adapted to the discharge port of the phase change point furnace, and a drive component 1 for controlling the rotation and lifting of the baffle 2. The output end of the drive component 1 is fixedly connected to the baffle 2, and the other end is fixedly connected to the column on the phase change point furnace. When the discharge port needs to be opened, the drive component 1 first drives the baffle 2 to descend vertically a certain distance, and then drives the baffle 2 to rotate horizontally a certain angle, so that the baffle 2 is misaligned with the discharge port, without affecting the material falling out. In this embodiment, the horizontal rotation angle of the baffle 2 is preferably 90°, which is convenient for the drive component 1 to control. When the discharge port needs to be closed, the drive component 1 first drives the baffle 2 to rotate horizontally, and then drives the baffle 2 to rise vertically to contact the discharge port, sealing the discharge port. In this embodiment, the baffle 2 can be prevented from deforming under high temperature environment during the opening and closing of the discharge port.
[0025] Furthermore, the driving component 1 is connected to the baffle 2 via a support member 3. The support member 3 includes a rotating arm 31 and a supporting arm 32. One end of the rotating arm 31 is fixedly connected to the output end of the driving component 1, and the other end is fixedly connected to one end of the supporting arm 32. The other end of the supporting arm 32 is fixedly connected to the baffle 2. In this example, the included angle between the rotating arm 31 and the supporting arm 32 is preferably 90°, which ensures the stability of the entire opening and closing device, reduces its vibration during the opening and closing process, and makes the entire opening and closing device structure more compact while avoiding interference between components, thus saving installation space.
[0026] In this embodiment, when the material in the phase change furnace has been heat-treated and needs to be discharged, the drive component 1 first drives the baffle 2 to descend a certain distance via the support component 3, and then drives the baffle 2 to rotate horizontally at a certain angle via the rotating arm 31. When the material is hoisted and the discharge port needs to be closed, the drive component 1 first drives the baffle 2 to rotate horizontally via the rotating arm 31, and then drives the baffle 2 to rise vertically via the support component 3 to seal and close the discharge port.
[0027] Furthermore, the support arm 32 passes through the baffle 2 and is threadedly connected to the baffle 2. In this way, the baffle 2 can move along the axial direction of the support arm 32 according to the distance between the discharge port of the phase change furnace and the ground, so that the opening and closing device is applicable to phase change furnaces of different specifications. In order to ensure the reliability of the connection between the support member 3 and the baffle 2, fasteners can also be set at the connection between the support member 3 and the baffle 2.
[0028] Furthermore, the driving component 1 is connected to the column via a fixed bracket 4, which improves the overall stability of the opening and closing device of this utility model.
[0029] In the above embodiments, the driving component 1 is preferably a rotary pressing cylinder. When the discharge port is opened, the air inlet of the rotary pressing cylinder opens and the air outlet closes. Gas is introduced into the air inlet through the air source, so that the pressure inside the rotary pressing cylinder is higher than the external pressure, driving the piston rod to move. The piston rod of the rotary pressing cylinder is fixedly connected to the rotating arm 31 of the support member 3. After the support member 3 drives the baffle 2 to move vertically downward a certain distance, the rotating arm 31, along with the adjusting screw of the rotary pressing cylinder, drives the baffle 2 to rotate horizontally at a certain angle. When it is necessary to close the discharge port, the rotary pressing cylinder closes the air inlet and opens the air outlet through the air supply from the air source. The piston is subjected to external pressure. First, the rotating arm 31, along with the adjusting screw of the rotary pressing cylinder, drives the baffle 2 to rotate horizontally. Second, the piston rod of the rotary pressing cylinder, through the support member 3, drives the baffle 2 to move vertically upward to seal and close the discharge port.
[0030] In the above embodiments, the axial direction of the phase change furnace is preferably perpendicular to the upper surface of the baffle 2.
[0031] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
[0032] It should be understood that this utility model is not limited to the content already described above, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
