Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically to a baking device for valve production. Background Technology

[0002] Valve baking is a key material handling step in a vacuum system, which aims to remove internal moisture and gas through high-temperature heating to improve the system's vacuum performance.

[0003] Before placing the valves in the oven, they need to be cleaned to remove surface dust and impurities. After cleaning and drying, the valves also need to be preheated to prevent material stress or deformation caused by sudden high temperatures. Current valve production baking equipment lacks the utilization of waste heat. This solution provides a valve production baking device that collects the waste heat of the oven and converts it into simultaneous internal and external drying and preheating of the cleaned valves. Utility Model Content

[0004] The present invention aims to at least solve the problem in the prior art that the drying and preheating of valves after cleaning requires an additional heat source.

[0005] This solution provides a baking device for valve production, achieved through the following specific technical means: It includes an oven and a pretreatment box located on one side of the oven. A rotating tube shaft is installed inside the pretreatment box, and a clamping seat is fixedly fitted at the top of the tube shaft. The clamping seat is used to clamp the valve at one side port, so that the inner cavity of the tube shaft aligns with the valve port. Simultaneously, a vertical tube rack is installed beside the clamping seat in the pretreatment box, with nozzles on the vertical tube rack facing the clamping seat. Both the tube shaft and the vertical tube rack are connected to the oven via pipes, and these pipes are also connected to a gas supply pipe. After baking in the oven, the high-temperature gas in the oven is mixed with outside air, cooled, and then enters the tube shaft and the vertical tube rack, achieving simultaneous drying and preheating of the valve's interior and exterior.

[0006] Preferred technical solution 1: The upper part of the tube shaft is fixedly fitted with a shaped disc in the middle of the drying chamber at the top of the pretreatment box. The slider fixed at the bottom of the vertical tube frame is slidably connected to the bottom wall of the drying chamber. At the same time, the vertical tube frame slides in contact with the side of the shaped disc. The side of the shaped disc is arc-shaped and close to the outer contour of the valve.

[0007] Preferred technical solution 2: A horizontal rail is fixed to the bottom wall of the drying chamber. The horizontal rail faces the radial direction of the tube axis. The slider slides along the horizontal rail, and a spring is connected between the slider and the end wall of the horizontal rail. The spring ensures the contact state between the vertical tube rack and the irregularly shaped plate.

[0008] Preferred technical solution 3: The bottom end of the tube shaft extends into the control cavity on the bottom side of the pretreatment box. A bevel gear 1 is fixedly sleeved on the bottom end of the tube shaft. At the same time, a motor is fixed in the control cavity. A bevel gear 2 fixed to the output shaft of the motor meshes with bevel gear 1.

[0009] Preferred technical solution four: The gripper seat is a three-jaw chuck.

[0010] The above structure gives this solution the following advantages:

[0011] 1. Collect and reuse the heat in the oven to provide a heat source for drying and preheating the valve after cleaning;

[0012] 2. The combination of the tube shaft, clamp seat, and vertical tube rack can simultaneously dry and preheat the inside and outside of the valve;

[0013] 3. The irregularly shaped disc and horizontal rail can be used to closely follow the outer contour of the valve for close-range drying and preheating. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 A baking device for valve production includes an oven 1 and a pretreatment box 2 located on one side of the oven 1. A tube shaft 3 rotates inside the pretreatment box 2. A clamp seat 4 is fixedly sleeved on the top of the tube shaft 3. The clamp seat 4 is used to clamp the valve at one side port. The clamp seat 4 is preferably a three-jaw chuck, so that the inner cavity of the tube shaft 3 is connected to the valve port. At the same time, a vertical tube rack 5 is installed on the side of the clamp seat 4 in the pretreatment box 2. The vertical tube rack 5 has nozzles facing the clamp seat 4 to blow air onto the outer wall of the valve placed on the clamp seat 4.

[0022] Both the tube shaft 3 and the vertical tube rack 5 are connected to the oven 1 through pipes 6. One set of pipes 6 is rotatably connected to the tube shaft 3, and the other set is directly connected to the vertical tube rack 5. At the same time, each set of pipes 6 is also connected to a gas supply pipe 7. After baking in the oven 1, the high-temperature gas in the oven 1 is mixed with the outside air and cooled before entering the tube shaft 3 and the vertical tube rack 5 to achieve synchronous drying and preheating of the inside and outside of the valve. The outer end of the gas supply pipe 7 and the connection end of the pipe 6 with the oven 1 are equipped with control valves. The opening and closing of the control valves controls the amount of high-temperature gas and outside air entering the oven 1.

[0023] Please see Figures 2-4 A baking device for valve production has a shaped disc 8 fixedly mounted on the upper part of the tube shaft 3, located at the top of the drying chamber of the pretreatment box 2. A slider 9 is fixed at the bottom of the vertical tube frame 5, and a horizontal rail 10 is fixed on the bottom wall of the drying chamber. The horizontal rail 10 faces the radial direction of the tube shaft 3. The slider 9 slides along the horizontal rail 10, and a spring 11 is connected between the slider 9 and the end wall of the horizontal rail 10. The spring 11 ensures the contact state between the vertical tube frame 5 and the shaped disc 8. The roller 12 mounted on the vertical tube frame 5 and the side of the shaped disc 8 always maintain sliding contact under the pull of the spring 11. The side of the shaped disc 8 is arc-shaped and close to the outer contour of the valve. During installation, the valve is clamped on the jaw seat 4, and the protruding valve head of the valve faces the side of the shaped disc 8 away from the tube shaft 3. When the jaw seat 4 drives the valve and the shaped disc 8 to rotate, the vertical tube frame 5 is close to the side of the shaped disc 8 and close to the outer contour of the valve for heat drying.

[0024] See Figure 2 The valve production baking device has a tube shaft 3 whose bottom end extends into the control cavity on the bottom side of the pretreatment box 2. A bevel gear 13 is fixedly sleeved on the bottom end of the tube shaft 3. At the same time, a motor 14 is fixed in the control cavity. The bevel gear 15 fixed on the output shaft of the motor 14 meshes with the bevel gear 13. The motor 14 controls the rotation of the tube shaft 3, which drives the valve and the eccentric disc 8 held by the clamping jaw seat 4 to rotate. The eccentric disc 8 is an eccentric disc.
