Detailed Implementation

[0019] 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.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses a heat treatment device for flange processing. A transmission sprocket 101 is rotatably connected to the front and rear side walls of the inner cavity of the outer shell 100. The transmission sprocket 101 supports the chain 102, facilitating its rotation. The chain 102 is sleeved on the outer wall of the transmission sprocket 101, facilitating the rotation of the driven sprocket 105. A movable frame 103 is slidably connected to the left and right side walls of the inner cavity of the outer shell 100, facilitating the movement of a rotating frame 104. Rotating frames 104 are rotatably connected to the left and right sides of the top wall of the movable frame 103. To facilitate the rotation of the flange and ensure uniform heating, the bottom end of the rotating frame 104 passes through the bottom wall of the movable frame 103 and is fixedly connected to a driven sprocket 105. The driven sprocket 105 facilitates the rotation of the rotating frame 104. The driven sprocket 105 meshes with the chain 102. Heating meshes 106 are fixedly connected to the left and right side walls of the inner cavity of the outer shell 100. The heating meshes 106 facilitate the heating of the flange. A motor 107 is fixedly connected to the bottom wall of the outer shell 100. The motor 107 facilitates the rotation of the front drive sprocket 101. The output end of the motor 107 is connected to the bottom end of the front drive sprocket 101.

[0021] In this embodiment: the flange to be processed is placed on the rotating frame 104, and the moving frame 103 is pushed to move the rotating frame 104. The rotating frame 104 then moves the flange to the inner cavity of the outer shell 100. The cover is closed, and the heating mesh 106 is activated for heating. The heating mesh 106 uses heating elements such as resistance wires and heating tubes, and heats the flange by the Joule heat generated when current passes through it. It has the advantages of fast heating speed, precise temperature control, and cleanliness, facilitating heat treatment of the flange. The motor 107 drives the front drive sprocket 101 to rotate, and the front drive sprocket 101 drives the chain 102 to rotate. The driven sprocket 105 of the chain 102 rotates, which in turn drives the rotating frame 104 to rotate. The rotating frame 104 facilitates the rotation of the flange, allowing the heating grid 106 to heat the flange evenly. After heat treatment, the rotating frame 104 is moved by pulling the movable frame 103. The movement of the rotating frame 104 causes the driven sprocket 105 to roll on the chain 102, making it easy to remove the flange from the inner cavity of the outer shell 100. This facilitates the removal and placement of the flange, allows for easy adjustment of the flange's heating position, and ensures even heating, preventing uneven heating from affecting the flange's quality.

The upper and lower side walls of the groove cavity are evenly rotatably connected to the rollers 109. The rollers 109 roll to avoid wear. The chain 102 is located on the outer wall of the rollers 109.

[0023] In this embodiment: the support frame 108 facilitates the support of the roller 109, and the roller 109 facilitates the limiting support of the movement of the chain 102. The rolling of the roller 109 avoids wear, and the device can easily support and limit the chain 102, prevent the chain 102 from deviating, and keep the chain 102 always engaged with the driven sprocket 105.

[0024] The outer wall of the roller 109 has an annular groove, and the chain 102 is located in the inner cavity of the annular groove.

[0025] In this embodiment, the ring groove is provided to facilitate the limiting of the chain 102, prevent the chain 102 from shifting due to gravity, and facilitate the engagement of the chain 102 with the driven sprocket 105.

[0026] The outer wall of the rotating frame 104 is uniformly fixedly connected with a hanger 110, which facilitates the support of the hook 111. The outer wall of the hanger 110 is uniformly fixedly connected with a hook 111, which facilitates the hanging of the flange. The top wall of the rotating frame 104 is fixedly connected with a fan blade 112, which facilitates the flow of hot air and makes the temperature uniform.

[0027] In this embodiment: the rotating frame 104 facilitates the rotation of the hanging frame 110, the hanging frame 110 facilitates the rotation of the hook 111, the hook 111 facilitates the rotation of the flange, and the setting of multiple sets of hooks 111 facilitates the placement of multiple sets of flanges, which facilitates the simultaneous processing of multiple sets of flanges and helps to improve work efficiency. The rotating frame 104 facilitates the rotation of the fan blade 112, and the fan blade 112 facilitates the flow of air in the inner cavity of the outer casing 100.

[0028] The left and right side walls of the inner cavity of the outer shell 100 are provided with slide rails 113, and the left and right side walls of the movable frame 103 are evenly provided with rotating wheels 114, which are located in the inner cavity of the slide rails 113.
