In the prior art, a heat treatment furnace is generally set up to perform sealed heating treatment on the stainless steel capillary. However, due to the speed and space of the fuel and air entering the heat treatment furnace, the combustion and heating effect in the furnace is limited, and the exhaust gas efficiency is reduced due to the sealing setting.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 6 As shown, the utility model provides a stainless steel capillary processing heat treatment device, including a heat treatment furnace 1, flamethrowers 2 are installed on the upper and lower sides of the heat treatment furnace 1, a one-way valve 3 is installed on the right side of the heat treatment furnace 1, and is used for one-way air intake of the inner cavity of the heat treatment furnace 1, an exhaust pipe 4 is installed on the left side of the heat treatment furnace 1, a worm gear case 5 is fixedly installed at the bottom of the exhaust pipe 4, a mounting plate 7 is rotatably installed inside the worm gear case 5 through a rotating shaft 6, cams 9 are fixedly installed at both ends of the rotating shaft 6, and two groups of front and rear fixing seats 10 are fixedly installed on the outer surface of the exhaust pipe 4, and the fixing seat 10 is movably sleeved inside A guide column 11, one end of which is fixedly connected to a limit plate 12, a spring 13 is movably sleeved on the outer surface of the guide column 11, a connecting column 15 is fixedly connected to the outer surface of the guide column 11, a connecting column 2 16 is fixedly connected to one side of the connecting column 15, a sealing block 17 is fixedly connected to one end of the connecting column 2 16, a limit column 19 is movably sleeved inside the sealing block 17, a sealing plate 20 is fixedly connected to the left end of the limit column 19, the sealing plate 20 is in contact with the sealing block 17, a venting groove 18 is provided in the middle of the sealing block 17, and the sealing block 17 is interference fit with the inner wall of the exhaust pipe 4;

[0022] This device has been redesigned to cleverly utilize the conversion between heat energy and mechanical energy generated by exhaust gas, thereby improving the exhaust gas emission efficiency. The thrust from the exhaust gas is converted into the rotational power of the cam 9 through the mounting plate 7, and the limiting plate 12 and the guide column 11 are pushed to drive the sealing block 17 to move outward toward the left of the inner wall of the exhaust pipe 4 under the elastic cooperation of the spring 13, and a negative pressure to the left is generated in the inner cavity of the exhaust pipe 4, thereby accelerating the exhaust gas emission speed of the inner cavity of the exhaust pipe 4. With the cooperation of the limiting column 19, the sealing plate 20 and the sealing block 17, the sealing block 17 opens the seal of the ventilation groove 18 when it returns to the right, thereby realizing the function of increasing the exhaust gas emission speed.

[0023] At the same time, by providing a spring 13, when the cam 9 is driven to rotate until its protrusion begins to move away from the limit plate 12, the rebound force generated pushes the protrusion of the cam 9, effectively reducing the friction resistance generated when the exhaust gas in the inner cavity of the exhaust pipe 4 is converted into the mechanical energy of the mounting plate 7. At the same time, the negative pressure generated when the sealing block 17 is pushed to the left by the piston component can also accelerate the airflow and increase the rotational torque of the mounting plate 7, the rotating shaft 6 and the cam 9, effectively saving electric energy.

[0024] A slide rail is installed at the bottom of the inner wall of the heat treatment furnace 1, and a mounting frame 8 is slidably installed through the slide rail. A plurality of capillary workpieces are placed on the top of the mounting frame 8. The rotating shaft 6 is rotatably installed on the inner wall of the worm gear housing 5 through a bearing.

[0025] The slide rail is used to install the mounting frame 8, and multiple groups of stainless steel capillary workpieces can be placed on the mounting frame 8. When the mounting frame 8 is slidably installed on the slide rail, support can be achieved.

[0026] The mounting plates 7 are arranged in eight groups and are distributed at equal angles in the inner cavity of the worm gear housing 5, and the axis of the exhaust pipe 4 is parallel to the horizontal tangent of the rotation of the mounting plates 7;

[0027] The mounting plates 7 are arranged in eight groups, which can generate automatic rotational power under the thrust of the exhaust gas generated in the inner cavity of the heat treatment furnace 1, drive the rotating shaft 6 and the cam 9 to make circular motion, and then drive the guide column 11 and the sealing block 17 to make linear reciprocating motion, thereby realizing the vacuum operation of the inner cavity of the exhaust pipe 4.

[0028] The right side of the limit plate 12 abuts against the outer surface of the cam 9, and the two ends of the spring 13 are elastically connected to the fixing seat 10 and the limit plate 12 respectively;

[0029] The limiting plate 12 is in contact with the cam 9 and is kept in close contact by a spring 13 . When the cam 9 rotates, the cam 9 and the limiting plate 12 can always be kept in contact with each other.

[0030] Among them, the front and rear sides of the bottom of the left end of the exhaust pipe 4 are both provided with a slot 14, and the connecting column 15 is movably connected to the slot 14;

[0031] The slot 14 allows the connecting column 15 to move back and forth inside, providing a lateral space for the movement of the connecting column 15.

[0032] The cross-section of the limiting column 19 is in a "T" shape, and a rubber block 21 is glued to the right side of the sealing plate 20, and the rubber block 21 is arranged in the ventilation groove 18 in an interference fit;

[0033] like Figure 3 As shown, the design of the “T”-shaped structure enables the sealing plate 20 to be hooked by the protrusion of the limiting column 19 when moving to the left, thereby preventing the sealing plate 20 from being completely separated from the sealing block 17.

[0034] The working principle of this utility model:

[0035] First, open the sealing door on the front of the heat treatment furnace 1, slide the mounting frame 8 with the capillary workpiece placed on the slide rail on the inner wall of the heat treatment furnace 1, and then close the sealing door. Then, the mounting frame 8 is baked with upper and lower flames through the flamethrower 2. At this time, the flamethrower 2 and the one-way valve 3 jointly supply air, and the generated exhaust gas enters the exhaust pipe 4 under the positive pressure in the inner cavity of the heat treatment furnace 1, and continuously pushes the mounting plate 7 and the rotating shaft 6 to rotate counterclockwise, driving the cam 9 to rotate, thereby abutting the limit plate 12, applying pressure, and driving the guide column 11, the connecting column 1 15, the connecting column 2 16 and the sealing block 17 to move to the left along the inner wall of the exhaust pipe 4. At this time, the sealing plate 20 is in the inertia. It moves downward toward the side close to the sealing block 17 and abuts against the sealing block 17, driving the rubber block 21 to get stuck in the ventilation groove 18 to form a seal, so that the sealing block 17 becomes a piston component moving to the right, and the exhaust gas inside the exhaust pipe 4 is drawn to the left, generating negative pressure. At this time, the speed at which the exhaust gas enters the inner cavity of the exhaust pipe 4 is accelerated, and drives the mounting plate 7, the rotating shaft 6 and the cam 9 to rotate faster. When the cam 9 rotates until its protrusion moves to the right, the guide column 11 resets to the right under the action of the spring 13 and the limit plate 12, driving the sealing block 17 to move to the right. At this time, the sealing plate 20 is pushed open by the pressure of the inner wall of the exhaust pipe 4, and the ventilation groove 18 is opened, so that the exhaust gas in the inner cavity of the exhaust pipe 4 is discharged.
