Description

Technical Field

[0001] The invention relates to the technical field of annealing mechanisms, in particular to an annealing mechanism for processing copper parts. Background Art

[0002] At present, annealing is a metal heat treatment process, which refers to the process of slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. Since the cooling speed during the solidification process of this process is very fast, segregation of zinc, nickel and other elements will occur in the copper tube. If the ingot with component segregation is directly subjected to pressure processing, it is easy to crack. Therefore, copper tubes are generally annealed to eliminate internal stress and improve the plasticity of the ingot.

[0003] The general production process of copper tubes is coiling, winding, bright annealing, and finished products. The annealing process is: after heating and annealing in a closed space, let the temperature slowly cool down to at least 500 degrees in a closed space and then cool naturally to have brightness, so that decarburization will not occur. In the production process of online annealing equipment for copper tube processing, high-purity nitrogen needs to be used as a protective gas for heating and annealing of copper tubes to prevent oxidation. Nitrogen can make the inner and outer surfaces of copper tubes bright and not oxidized, and prevent air from oxidizing copper tubes at high temperatures, affecting the quality of copper tubes.

[0004] In the above process, since the copper tube used for online annealing is long, more nitrogen needs to be introduced. It is difficult to detect whether the nitrogen fills the copper tube when it is introduced, so it is difficult to accurately control the amount of nitrogen, which easily causes a large amount of nitrogen waste and reduces resource utilization.

DETAILED DESCRIPTION

[0032] The embodiment of the present invention provides an annealing mechanism for processing copper parts, such as Figure 1-7As shown, it is used to monitor the nitrogen content, including a base 1, a frame supporting the copper piece is connected to the top of the base 1, and a shell cover 2 is suspended above the base 1. When the shell cover 2 is lowered to the lowest point, it conflicts with the base 1 and covers the frame. Nitrogen is flushed into the shell cover to anneal the copper piece.

[0033] A vertical column 3 is fixedly installed at the front end of the base 1 , and a plurality of connecting pipes 31 are fixedly installed on the column 3 . The plurality of connecting pipes 31 are connected to the front end of the shell cover 2 in a butt connection.

[0034] A plurality of detection chambers 32 are provided in the column 3 from bottom to top, and the detection chambers 32 are connected to the inside of the shell cover 2 through the connecting pipe 31. A sensing component 1 is provided in the detection chamber 32, and a cavity 15 is provided in the base 1, and a sensing component 2 is placed in the cavity 15.

[0035] An exhaust pipe 34 is fixedly installed outside the column 3, and the exhaust pipe 34 is connected to the multiple detection chambers 32, and the lower end of the exhaust pipe 34 is connected to the cavity 15 for introducing gas into the cavity 15. When the sensing component 1 and the sensing component 2 send feedback to the outside at the same time, it indicates that nitrogen fills the shell 2.

[0036] The first sensing component includes a temperature conducting tube 4, a power supply 35, an NTC thermistor 36 and an electromagnet module 37. The temperature conducting tube 4 is horizontally plugged outside the column 3, one end of the temperature conducting tube 4 extends into the detection chamber 32, and the power supply 35 is fixedly installed at the bottom of the inner wall of the detection chamber 32. The NTC thermistor 36 is placed above the power supply 35, and the electromagnet module 37 is placed above the NTC thermistor 36. The NTC thermistor 36 and the electromagnet module 37 are fixedly connected to the inner wall of the detection chamber 32.

[0037] The electromagnet module 37 is aligned with the temperature conducting tube 4, and the power supply 35, the NTC thermistor 36 and the electromagnet module 37 are connected in series. The NTC thermistor 36 has a negative temperature coefficient, and the resistance value is smaller when the temperature is higher, and the resistance value is larger when the temperature is lower.

[0038] The heating module 33 is also included. The heating module 33 is fixedly mounted on the bottom of the inner wall of the detection chamber 32. The heating module 33 is aligned with the NTC thermistor 36. A support rod 42 is welded in the length direction of the temperature conducting tube 4. A tension sensing unit 41 is fixedly mounted on one end of the support rod 42 away from the electromagnet module 37. The support rod 42 is slidably matched with a permanent magnet 43. A spring 44 is fixedly mounted between the tension sensing unit 41 and the permanent magnet 43.

[0039] Working principle: nitrogen is injected into the shell cover 2, and the air in the shell cover 2 is pressed into the detection chamber 32 of the column 3. The heating module 33 generates heat and transfers it to the NTC thermistor. At this time, the resistance of the NTC thermistor 36 is too small, and the current entering the electromagnet module 37 becomes larger, so that the magnetic force generated by the electromagnet module 37 is stronger. The permanent magnet 43 is attracted by the magnetic force to approach the electromagnet module 37, and the spring 44 is stretched to apply force to the tension sensing unit 41, and the tension sensing unit 41 feeds back the measured force to the computer terminal.

[0040] Then, since nitrogen is lighter than air, the detection chamber 32 is filled with nitrogen from top to bottom, and the air is pressed into the cavity 5 through the exhaust pipe 34.

[0041] According to another characteristic of nitrogen, nitrogen has poor thermal conductivity. When nitrogen fills the detection chamber 32, the temperature cannot be transmitted to the NTC thermistor 36, and the resistance value of the NTC thermistor 36 increases. At this time, the current entering the electromagnet module 37 becomes weaker, resulting in a weakening of the magnetic force generated by the electromagnet module 37. The permanent magnet 43 is weakened by the magnetic attraction, resulting in a weakening of the force applied to the tension sensing unit 41.

[0042] When the value measured by the tension sensing unit 41 decreases to a certain range and remains stable, it means that the nitrogen has completely filled the detection chamber 32 .

[0043] The second induction component includes a base 5, an igniter 6 and a fireproof cloth 7. The base 5 is fixedly installed at the bottom of the inner wall of the cavity 15. A paddle 52 is hinged on the side of the base 5. A steel wire 71 is fixedly tied to the side of the fireproof cloth 7. The lower end of the steel wire 71 is fixedly tied to the end of the paddle 52.

[0044] It also includes a laser emitter 53 and a beam capturing unit. The laser emitter 53 is fixedly mounted on the bottom of the paddle 52, and the beam capturing unit is fixedly mounted on the bottom of the inner wall of the cavity 15. When the laser emitter 53 falls naturally, the light emitted by the laser emitter 53 is captured by the beam capturing unit.

[0045] Working principle: During the annealing operation, the igniter 6 generates a flame, and the generated hot air flow lifts the protective cloth 7. The fireproof cloth 7 pulls the steel wire 71, and the steel wire 71 pulls the paddle 52 to tilt up. At this time, the light emitted by the laser emitter 53 cannot irradiate the beam capture unit.

[0046] The rear end of the entire cavity 15 is connected to an exhaust gas discharge pipe. The flame needs to consume air, and the air is gradually consumed. After nitrogen enters the cavity 15, the flame is extinguished, the fireproof cloth sinks, and the paddle 52 droops naturally, and the light emitted by the laser emitter 53 is captured by the beam capture unit.

[0047] A wire mesh is set up between the fireproof cloth 7 and the igniter 6. The fireproof cloth 7 sinks and falls on the wire mesh, and the fireproof cloth 7 covers the igniter 6. The wire mesh edge is welded to the inner wall of the cavity 15.

[0048] A groove 51 is formed at the bottom of the base 5 , and the groove 51 is aligned with the igniter 6 . The paddle 52 is hinged in the groove 51 . The igniter 6 is fixedly mounted with a gas pipe 61 , and the gas pipe 61 extends vertically downward to the outside of the base 1 .

[0049] The exhaust pipe 34 has a branch on its side, which extends into the column 3 and is connected to the bottom of the detection chamber 32 .

[0050] A plurality of pairs of support plates 11 are fixedly mounted on the top of the base 1, and a placement slot 12 is provided between two support plates 11 in the same group. A motor-driven roller 13 is pivotally connected between the placement slot 12 and the support plate 11, and a fan blade 14 is welded to the shaft of the roller 13. The fan blade 14 is driven to rotate slowly by the roller 13, which plays a role in assisting the movement of the airflow.

[0051] A counterweight block 21 is fixedly installed on the outer side of the shell cover 2, and an air delivery pipe 22 is fixedly installed on the bottom of the rear end of the shell cover 2.

[0052] In summary, the annealing mechanism for processing copper parts is composed of a base 1, a shell cover 2, and a column 3. A heating module 33, a power supply 35, an NTC thermistor 36, and an electromagnet module 37 are arranged in the column 3. According to the poor thermal conductivity of nitrogen, the strength of the magnetic field of the electromagnet module 37 is changed, and then the tension sensing unit 41, the support rod 42, the permanent magnet 43, and the spring 44 are cooperated to sense the strength of the magnetic field of the electromagnet module 37 to judge the nitrogen content.

[0053] In addition, a base 5, an igniter 6, and a fireproof cloth 7 are provided in the base 1. A paddle 52 is hinged on the side of the base 5. The paddle 52 is provided with a laser emitter 53, and a light beam capture unit is placed in the cavity 15. With the non-combustible property of nitrogen, after the fireproof cloth 7 sinks, the laser emitter 53 emits light to illuminate the light beam capture unit, thereby achieving the purpose of secondary detection, improving detection accuracy, and avoiding excessive waste of nitrogen.
