Description

Technical Field

[0001] The invention relates to the technical field of annealing treatment of titanium alloys in mines, and in particular to a heat treatment annealing production line for titanium and titanium alloy metal materials. Background Art

[0002] In the production and processing of titanium alloy products, in order to effectively eliminate the internal stress during the processing, it is generally necessary to anneal the processed titanium alloy products. During the annealing process, the most common operation is to eliminate the internal stress through the heating and cooling process;

[0003] When annealing titanium alloy ball products, the titanium alloy production line in the prior art often needs to use a support tray for lifting and heating. In specific operations, the support tray and the alloy ball are placed in an annealing furnace for heating. After heating for a period of time, the alloy ball is manually taken out for cooling. The residual internal stress in the processed alloy ball can be effectively eliminated through annealing heating and cooling treatment. However, this heating method may cause poor heating effect on the contact surface between the alloy product and the support tray, which may cause uneven overall heating and affect the consistency and stability of product quality. Summary of the invention

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] Example:

[0038] A heat treatment annealing production line for titanium and titanium alloy metal materials, comprising:

[0039] A table top 1 fixedly connected with a bracket 101;

[0040] A support plate 2 is fixedly connected to the table top 1;

[0041] The insulation sleeve 12 is fixedly connected to the support plate 2;

[0042] A parabola-shaped heating ring 2011 is connected to the support plate 2;

[0043] The heating ring 2011 is placed in the insulation sleeve 12, and the parabolic heating ring 2011 matches the arc insulation sleeve 12;

[0044] The transmitting unit 102 is fixedly connected to the table 1;

[0045] A cooling box 3 having a receiving portion is fixedly connected to the table 1;

[0046] The cooling pipe 501 is fixedly connected to the cooling box 3, and the cooling pipe 501 faces the receiving portion;

[0047] The cooling box 3 is provided with a through hole 301 for the alloy ball 1021 to be introduced.

[0048] The launching part 102 ejects the alloy ball 1021 obliquely upward, and the ejected alloy ball 1021 moves in a parabolic shape and is annealed and heated by the heating ring 2011 . The heated alloy ball 1021 falls into the receiving part in the cooling box 3 .

[0049] Ginseng Figure 1 , Figure 2 It should be noted that the launching unit 102 is a catapult available on the market, and the ejection force of the catapult can be adjusted according to production requirements;

[0050] It should also be noted that the launching portion 102 is tilted to ensure that the alloy ball 1021 can be stably thrown out in a set parabola when it is ejected.

[0051] In the specific implementation process, the alloy ball 1021 can generally be a small-diameter sphere with a diameter not greater than 2 cm, and the launch unit 102 can have a built-in launch chip to ensure that the launch unit 102 can launch the alloy ball 1021 at a stable launch speed and launch angle.

[0052] Reference Figure 4 A commercially available electromagnetic heater 201 is fixedly connected to the support plate 2 , and the electromagnetic heater 201 is connected to the heating ring 2011 . During the actual annealing operation, the electromagnetic heater 201 is started, and the electromagnetic heater 201 will heat the heating ring 2011 .

[0053] Reference Figure 1-Figure 3 During the annealing operation, the launch unit 102 ejects the alloy ball 1021 in a parabolic shape, and the ejected alloy ball 1021 passes through the heating ring 2011. At this time, the heating ring 2011 can heat the passing alloy ball 1021, thereby completing the annealing heating operation;

[0054] It should be noted that the moving trajectory of the alloy ball 1021 is consistent with the shape of the arc-shaped heating ring 2011 to ensure that the alloy ball 1021 can pass through the heating ring 2011 without contacting the heating ring 2011 .

[0055] Reference Figure 4 , Figure 5, a driving motor 202 is fixedly connected to the support plate 2, a connecting rod 2021 is fixedly connected to the driving end of the driving motor 202, and the connecting rod 2021 is fixedly connected to the driving rod 7;

[0056] In actual operation, the driving motor 202 drives the connecting rod 2021 and the driving rod 7 to rotate, and the driving rod 7 drives the receiving portion to rotate.

[0057] Reference Figure 3 , Figure 8 After annealing and heating, the alloy ball 1021 will fall onto the buffer net 11 through the through hole 301. At this time, the buffer net 11 will tend to move downward after receiving the alloy ball 1021. At this time, the buffer spring 1002 connected around the buffer net 11 can effectively remove the impact force of the alloy ball 1021 on the buffer net 11, thereby reducing the interaction force between the alloy ball 1021 and the buffer net 11, ensuring that the alloy ball 1021 will not be deformed due to a large impact force when it falls on the buffer net 11.

[0058] The titanium alloy ball 1021 is annealed by means of the device. When the alloy ball 1021 is heated, it does not contact the heating ring 2011, and during the annealing heating process, a support tray is no longer needed for lifting and heating annealing, thereby ensuring the heating uniformity of the alloy ball 1021. This effectively solves the problem in the prior art of using a support tray for lifting and heating, resulting in poor heating effect on the contact surface between the alloy ball 1021 and the support tray, thereby improving the overall heating uniformity and the production quality of the alloy ball 1021.

[0059] It should be noted that the buffer net 11 is made of high temperature resistant carbon fiber ropes available on the market.

[0060] Reference Figure 3 , Figure 8 The alloy ball 1021 dropped on the buffer net 11 will move with the bracket 10. During the rotation and movement of the alloy ball 1021, the air pump 5 is started, and the air pump 5 will extract the inert gas after external cooling. The extracted inert gas will be blown out through the cooling pipe 501. The cooled inert gas can perform air cooling on the alloy ball 1021 in the net, thereby avoiding the problem of slow cooling efficiency at room temperature in the prior art. At the same time, by blowing inert gas, the oxygen concentration in the cooling box 3 can be effectively reduced, thereby reducing the possibility of surface oxidation of the alloy ball 1021.

[0061] Reference Figure 3 , Fig. 9It should be noted that the gas blown out by the cooling pipe 501 will also blow the bracket 10 to cause a slight left and right swing. The slight left and right swing of the bracket 10 will drive the alloy ball 1021 in the buffer net 11 to slide back and forth. The back and forth sliding of the alloy ball 1021 changes the windward side of the ball, so that different positions of the alloy ball 1021 can be blown and cooled by the cooling pipe 501, thereby ensuring that the cooling pipe 501 can evenly cool the alloy ball 1021, thereby improving the cooling effect.

[0062] During specific implementation, helium may be used as the inert gas.

[0063] Reference Figure 8 The receiving part includes a driving rod 7, a support arm 701, a triangular arm 7011 and a bracket 10. The driving rod 7 is rotatably connected to the cooling box 3. The support arm 701 is fixedly connected to the driving rod 7. The triangular arm 7011 is rotatably connected to the support arm 701. A buffer spring 1002 is fixedly connected to the bracket 10, and a buffer net 11 is fixedly connected to the buffer spring 1002.

[0064] Reference Figure 8 , Fig. 9 A counterweight block 1001 is fixedly connected to the bottom of the bracket 10.

[0065] In specific implementation, the weight and installation position of the counterweight block 1001 can be adjusted according to the time annealing production requirements to ensure that the center of gravity of the receiving part is low, thereby ensuring the stability of the bracket 10, and thereby ensuring that the receiving surfaces of the bracket 10 and the buffer net 11 can be stably facing upward.

[0066] A discharge pipe 8 is fixedly connected to the cooling box 3, and a sensor 303 and an electric push rod 304 are also fixedly connected in the cooling box 3. A push plate 302 is fixedly connected to the driving end of the electric push rod 304. When the bracket 10 drives the alloy ball 1021 to rotate, the sensor 303 detects the temperature of the alloy ball 1021 and pushes the alloy ball 1021 out of the bracket 10 through the electric push rod 304. The pushed alloy ball 1021 rolls out from the discharge pipe 8.

[0067] Reference Fig. 9 The sensor 303 is an infrared thermal sensor available on the market, and the sensor 303 is connected to the electric push rod 304 .

[0068] It should be noted that the sensor 303 and the electric push rod 304 are connected through a controller. When the sensor 303 senses that the surface temperature of the alloy ball 1021 reaches the standard, the controller will control the electric push rod 304 to work, and the electric push rod 304 will push the push plate 302 to extend quickly. When the push plate 302 is extended, the push plate 302 just instantly pushes the alloy ball 1021 in the buffer net 11. The alloy ball 1021 that is instantly impacted will be pushed out from the buffer net 11 on the bracket 10. At this time, the flying alloy ball 1021 will fall into the cooling box 3. The alloy ball 1021 that falls into the cooling box 3 rolls and finally rolls out through the discharge pipe 8 connected to the lowest end.

[0069] Reference Fig. 9 It should also be noted that the push plate 302 is a semi-arc plate, which can be stably pushed out from the left side when the alloy ball 1021 is impacted instantly.

[0070] The table top 1 is fixedly connected with an air cylinder 4, the air cylinder 4 is fixedly connected with an air outlet pipe 402, the air outlet pipe 402 is fixedly connected with an air supply pipe 9, the air supply pipe 9 is fixedly connected with a cooling pipe 901, and the cooling pipe 901 is connected with the discharge pipe 8.

[0071] Reference Figure 2 The air delivery pipe 9 is wound around the discharge pipe 8 to ensure the cooling effect on the discharge pipe 8.

[0072] The driving rod 7 is fixedly connected with a rotating rod 601 , the rotating rod 601 is fixedly connected with a convex plate 6 , the air cylinder 4 is slidably connected with a sliding plug 403 , the sliding plug 403 is fixedly connected with a pressing rod 404 , and the driving end of the convex plate 6 abuts against the pressing rod 404 .

[0073] Reference Figure 6 A driving ball 4041 is fixedly connected to the top of the pressure rod 404, and the driving ball 4041 abuts against the convex plate 6. By setting the driving ball 4041, the convex plate 6 can push the pressure rod 404 more smoothly.

[0074] Reference Figure 2-Figure 3 , Figure 5-Figure 6 When the driving rod 7 rotates, the driving rod 7 will also drive the rotating rod 601 to rotate synchronously. The rotation of the rotating rod 601 will drive the convex plate 6 to rotate. When the convex plate 6 rotates, it will squeeze and push the pressure rod 404 to move. The movement of the pressure rod 404 will push the sliding plug 403 to slide down. The sliding of the sliding plug 403 will squeeze the gas in the gas cylinder 4. At this time, the gas in the gas cylinder 4 will be discharged through the air outlet pipe 402. The discharged gas will be transported through the air supply pipe 9, and finally blown into the discharge pipe 8 through the cooling pipe 901, so that the alloy ball 1021 rolling down in the discharge pipe 8 can be cooled for a second time, which further improves the cooling effect on the alloy ball 1021.

[0075] Reference Figure 5 , Figure 6When the driving end of the convex plate 6 rotates past the driving ball 4041, the squeezing force on the driving ball 4041 disappears, and the sliding plug 403 slides up and resets under the reset tension of the tension spring 405. When the sliding plug 403 is reset, the air cylinder 4 will draw outside air through the air inlet pipe 401, and the drawn air is stored in the air cylinder 4, so that it can be pushed out when the sliding plug 403 slides down next time.

[0076] In a specific implementation, the air inlet pipe 401 may be connected to an external cold air tank, and the cooling gas may be delivered to the air delivery pipe 9 , thereby further ensuring the cooling effect on the alloy ball 1021 .

[0077] A deceleration brush 801 is fixedly connected to the inner wall of the discharge pipe 8 , and multiple groups of deceleration brushes 801 are evenly distributed on the inner wall of the discharge pipe 8 .

[0078] Reference Figure 5-Figure 7 When the alloy ball 1021 rolls out through the discharge pipe 8, the alloy ball 1021 will be blocked by the deceleration brush 801 in the discharge pipe 8, thereby slowing down the falling speed of the alloy ball 1021, thereby extending the cooling time of the alloy ball 1021 in the discharge pipe 8, and further improving the cooling effect on the alloy ball 1021.

[0079] In a specific implementation, the deceleration brush 801 can also brush off the oxide layer on the surface of the alloy ball 1021 , thereby ensuring the cleanliness of the surface of the alloy ball 1021 .

[0080] A tension spring 405 is fixedly connected to the sliding plug 403 , and one end of the tension spring 405 away from the sliding plug 403 is fixedly connected to the top wall of the air cylinder 4 .

[0081] Reference Figure 5 , Figure 6 By setting the tension spring 405 on the sliding plug 403, the sliding plug 403 can be quickly reset.

[0082] An air inlet pipe 401 is fixedly connected to the side wall of the air cylinder 4, and both the air inlet pipe 401 and the air outlet pipe 402 are provided with a one-way valve.

[0083] Reference Figure 2 An air pump 5 is fixedly connected to the table top 1 , and an air outlet end of the air pump 5 is connected to the cooling pipe 501 .

[0084] Reference Figure 2 It should be noted that the air inlet end of the air pump 5 can be connected to an external air storage tank, and the air storage tank can store cooled inert gas.

[0085] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
