Detailed Description
To make the objects, technical solutions and advantages of the present invention more clearly understood, the following description is given for further details of the present invention with reference to the accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention, and are not intended to limit the present invention.
Referring to fig. 1-7, the present invention provides an argon protection device for induction brazing, which comprises a hollow tube 1, a solid tube 2, a quartz tube 5 and a fixing plate 3; the solid tube 2 is sleeved on the hollow tube 1, a quartz tube 5 is arranged at the joint of the solid tube 2 and the hollow tube 1, two ends of the quartz tube 5 are connected with a fixing piece 3, and two holes are arranged on the quartz tube 5 and respectively provided with an air inlet 6 and an air outlet 7. One end of the solid tube 2 of the utility model is provided with a step 9, and the solid tube 2 is sleeved with the hollow tube 1 through the step 9; after the hollow tube 1 and the solid tube 2 are sleeved, the quartz tube 5 is sleeved at the joint of the solid tube 2 and the hollow tube 1, the diameter of the quartz tube 5 is larger than that of the hollow tube 1, and the diameter of the quartz tube 5 is larger than that of the solid tube 2, so that the joint of the hollow tube 1 and the solid tube 2 can be sleeved, and a space for containing argon can be reserved; after the quartz tube 5 is sleeved, the sealing gaskets 8 are sleeved at two ends of the quartz tube 5, specifically, the sealing gaskets 8 are provided with step parts 10, the step parts are inserted into the quartz tube 5, argon can be prevented from leaking out of the two ends of the quartz tube 5, and the sealing gaskets 8 can play a role in sealing; then connect stationary blade 3 again, stationary blade 3 is equipped with two connectors, and a connector is connected with quartz capsule 5, and another connector is connected with fixed sleeving 4. The fixing piece 3 is connected with the fixing sleeve 4 through a bolt, and an elastic gasket is arranged between the fixing sleeve 4 and the bolt. The function of the fixing plate is to play a role of connection on one hand and to play a role of stabilizing the quartz tube 5 on the other hand.
The utility model discloses a concrete working process for argon protection device when response is brazed: the upper end of the fixing piece 3 is matched with the metal workpiece, and the lower end is in threaded connection with the fixing sleeve 4. When in work, the whole device is assembled. Two holes are formed in the upper portion of the quartz tube 5, one hole is used for introducing argon gas, the other hole is used for discharging argon gas, when the brazing is needed, the air inside the quartz tube 5 is exhausted, and the argon gas is heated again to ensure that the inside of the quartz tube 5 is completely filled with the argon gas. It should be noted that the fixing plate 3 is sleeved on the workpiece, although a small amount of axial movement is achieved, all parts in the argon system move synchronously for the whole argon system, so that the sealing performance of the argon system is not affected, moreover, the device is provided with the air outlet, and when heating is carried out, the temperature in the quartz tube 5 is high, so long as the continuous argon flowing during heating is ensured to enter the quartz tube 5, and the outside air cannot enter the quartz tube 5 in a reverse flow manner.
It should be noted that, in practical implementation, an elastic gasket may be disposed at the threaded connection between the two ends of the fixing sleeve 4 and the fixing plate 3, because the upper end of the fixing plate 3 is attached to the sealing pad 8, when the fixing plate 3 is stressed, a compressive force is necessarily generated on the sealing pad 8, and if the elastic gasket is not disposed, after the system is assembled, the distance between the two fixing plates will be equal to the distance between the fixing sleeve 4 and the sealing pad 8, in other words, the sealing performance between the two ends of the quartz tube 5 is not good.
It should be noted that, when the workpiece is heated, the alternating magnetic field generated by the induction coil only heats the metal, and does not heat the quartz tube 5, so that the quartz tube 5 is not cracked due to high temperature, and when the workpiece is heated, the induction coil is sleeved on the quartz tube 5, and the alternating magnetic field is only generated inside the coil, and does not heat the fixing sleeve 4.
The embodiment of the present invention is the above. The specific parameters in the above embodiments and embodiments are only for the purpose of clearly expressing the verification process of the present invention, and are not used to limit the patent protection scope of the present invention, the patent protection scope of the present invention is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and the drawings of the present invention should be included in the protection scope of the present invention.
