Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy processing, in particular to a swing-type quenching device for processing titanium alloy forgings. Background Art

[0002] Titanium is an important structural metal developed in the 1950s. Titanium alloy is an alloy based on titanium with other elements added. Titanium alloy has high strength, good corrosion resistance and high heat resistance. Titanium alloy has the advantages of light weight, high specific strength and good corrosion resistance. It is widely used in many industrial fields such as heavy machinery, trains, energy, aerospace, etc.

[0003] According to the search, Chinese patent literature, announcement number: CN215856230U, discloses a quenching device for titanium alloy forgings. The servo motor rotates under the action of the belt to drive the moving rod to move up and down, which is convenient for spraying water according to forgings of different heights. The first bevel gear and the second bevel gear are driven to mesh and rotate by the forward and reverse motor, so that the worm drives the worm wheel to mesh and rotate, thereby driving the swing plate to swing left and right, so that the nozzle can swing left and right to spray water and cool evenly. However, this quenching device for titanium alloy forgings sprays water by swinging the nozzle left and right, and there will be a dead angle for spraying during the spraying quenching process, which makes it impossible to quench the entire titanium alloy forging in all directions, thereby affecting the entire titanium alloy forging. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a swing-type quenching device for titanium alloy forging processing, which has the advantages of simple operation, convenient use, uniform quenching without dead angles, etc., and solves the above technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a swing-type quenching device for processing titanium alloy forgings, comprising a quenching box, bearings are installed at both ends of the quenching box, a fixing rod is installed on the inner wall of the bearing, a sleeve is installed on the surface of the fixing rod, brackets are installed at both ends of the sleeve, a support plate is installed at the end of the bracket, a gear plate is installed at the front end of the surface of the fixing rod, a support plate is installed at the front end of the quenching box, a servo motor is installed on the upper surface of the support plate, a rotating rod is installed on the output shaft of the servo motor, a transmission gear is installed at the end of the rotating rod, a support frame is installed around the quenching box, a water tank is installed in the middle of the bottom end of the support frame, and a water pipe is installed on one side of the water tank.

[0008] Preferably, the connection between the bracket and the support plate is rotatably connected via a pin, and a fixing block is installed on the lower surface of the support plate.

[0009] Through the above technical solution, through the combination of the pin shaft and the fixed block, the support plate can always remain vertical, and even if the bracket swings, the support plate will not deviate from the vertical direction, ensuring the correct position of the workpiece during quenching and avoiding deformation and uneven cooling problems.

[0010] Preferably, the gear plate is meshed with the transmission gear.

[0011] Through the above technical solution, the gear plate installed on the front end of the fixed rod surface is meshed with the transmission gear installed on the output shaft of the servo motor, and the servo motor is used to control the swing of the bracket. This not only can achieve precise motion control, but also can adjust the frequency, amplitude and time of the swing as needed to meet the quenching requirements of different workpieces.

[0012] Preferably, a water pump is installed inside the water storage tank, and the water pipe is connected to the output shaft of the water pump.

[0013] Through the above technical solution, cooling water can be pumped into the quenching box through a water pump to achieve water circulation. The water circulation can ensure the uniform distribution of water temperature during the quenching process and avoid the problem of uneven cooling of the workpiece due to water temperature differences.

[0014] Preferably, a connecting pipe is provided between the quenching tank and the water storage tank, and a control valve is installed on the surface of the connecting pipe.

[0015] Through the above technical solution, by installing the connecting pipe and the control valve, the water level in the quenching box can be ensured to remain stable. The control valve can adjust the inflow and outflow of water as needed to keep the water level in the quenching box within a suitable range, and maintain the water level stability of the quenching box and the consistency of the quenching medium. During the quenching process, the stability of the water level is crucial to the quenching effect. By controlling the water flow in the connecting pipe, the concentration and temperature of the quenching medium can be kept stable, ensuring that the quenching effect of the workpiece is stable and reliable.

[0016] Preferably, a temperature sensor is installed on the inner wall of the right side of the quenching box.

[0017] Through the above technical solution, by installing a temperature sensor, the temperature changes in the quenching box can be monitored in real time. Once the temperature exceeds the set threshold, the temperature sensor will send a signal to indicate that the quenching water temperature needs to be lowered. At this time, opening the water circulation can introduce new cold water to lower the water temperature, ensuring that the temperature in the quenching box is always within a reasonable range, so as to ensure the stability and reliability of the quenching quality.

[0018] Compared with the prior art, the utility model provides a swing-type quenching device for titanium alloy forgings processing, which has the following beneficial effects:

[0020] 2. In the utility model, cooling water can be pumped into the quenching box through a water pump to realize water circulation. The water circulation can ensure the uniform distribution of water temperature during the quenching process and avoid the problem of uneven cooling of the workpiece due to water temperature differences. At the same time, the water circulation can also take away the heat generated during the quenching process, keep the water temperature stable, and improve the quenching effect.

[0027] Specifically, the connection between the bracket 5 and the support plate 6 is rotatably connected by a pin shaft 15, and a fixing block 16 is installed on the lower surface of the support plate 6. The advantage is that, through the combination of the pin shaft 15 and the fixing block 16, the support plate 6 can always remain vertical, and even if the bracket 5 swings, the support plate 6 will not deviate from the vertical direction, ensuring the correct position of the workpiece during the quenching process and avoiding the problems of deformation and uneven cooling.

[0028] Specifically, the gear plate 7 is meshed with the transmission gear 11. The advantage is that the gear plate 7 installed on the front end of the surface of the fixed rod 3 is meshed with the transmission gear 11 installed on the output shaft of the servo motor 9, and the servo motor 9 is used to control the swing of the bracket 5, which can not only achieve precise motion control, but also adjust the frequency, amplitude and time of the swing as needed to meet the quenching requirements of different workpieces.

[0029] Specifically, a water pump 17 is installed inside the water storage tank 13, and the water pipe 14 is connected to the output shaft of the water pump 17. The advantage is that cooling water can be pumped into the quenching box 1 through the water pump 17 to achieve water circulation. The water circulation can ensure the uniform distribution of water temperature during the quenching process, avoiding the problem of uneven cooling of the workpiece due to water temperature differences. At the same time, the water circulation can also take away the heat generated during the quenching process, keep the water temperature stable, and improve the quenching effect. By controlling the operation of the water pump 17, the water circulation speed and flow rate can be flexibly adjusted according to the specific quenching requirements and workpiece characteristics.

[0030] Specifically, a connecting pipe 18 is provided between the quenching box 1 and the water storage tank 13, and a control valve 19 is installed on the surface of the connecting pipe 18. The advantage is that by installing the connecting pipe 18 and the control valve 19, the water level of the quenching box 1 can be ensured to remain stable, and the control valve 19 can adjust the inflow and outflow of water flow as needed to keep the water level in the quenching box 1 within a suitable range, and keep the water level of the quenching box 1 stable and the consistency of the quenching medium.

The advantage is that by installing the temperature sensor 20, the temperature change in the quenching box 1 can be monitored in real time. Once the temperature exceeds the set threshold, the temperature sensor 20 will send a signal to prompt that the quenching water temperature needs to be lowered. At this time, opening the water circulation can introduce new cold water to lower the water temperature, ensuring that the temperature in the quenching box 1 is always within a reasonable range, so as to ensure the stability and reliability of the quenching quality.

Since the connection between the bracket 5 and the support plate 6 is rotatably connected by the pin 15, and the support plate 6 can always remain vertical, when the bracket 5 rotates, the support plate 6 will rotate with the pin 15 as the rotating axis. Since cooling water is injected into the quenching box 1, when the support plate 6 is at the bottom, it will fall into the cooling water injected into the quenching box 1 for quenching and cooling, and the temperature change in the quenching box 1 can be monitored by the temperature sensor 20 installed on the right inner wall of the quenching box 1. Once the temperature exceeds the set threshold, the temperature sensor 20 will send a signal to prompt that the quenching water temperature needs to be lowered. At this time, the water pump 17 pumps the cooling water into the quenching box 1 through the water pump 17 to realize water circulation.
