Description

Technical Field

[0001] The utility model relates to a high-frequency brazing machine, in particular to a double-station high-frequency brazing machine. Background Art

[0002] When the high-frequency brazing machine is working, the workpieces are assembled together in an overlapping manner, and the brazing filler metal is placed near or between the joint gaps. When the workpieces and the brazing filler metal are heated to a temperature slightly above the melting point of the brazing filler metal, the brazing filler metal melts (the workpieces are not melted) and is sucked into the gap between the solid workpieces by capillary action, filling the gap between the solid workpieces. The liquid brazing filler metal and the workpiece metal diffuse and dissolve into each other, and after cooling, a brazed joint is formed.

[0003] When using existing high-frequency brazing machines, nitrogen is usually introduced into the welded parts to prevent oxidation due to high temperature. However, the facilities currently used to introduce nitrogen are usually fixed, resulting in a relatively single location for nitrogen release. The range in which it can produce anti-slip oxidation effects is small, and therefore the anti-oxidation effect is relatively general. Utility Model Content

[0004] The purpose of the utility model is to provide a double-station high-frequency brazing machine, which can change the position of the diversion outlet in real time so that the nitrogen released from the diversion outlet can be more dispersed, thereby expanding the position of the nitrogen distribution, facilitating the anti-oxidation of the inner wall of the weldment in a larger range, and having a better anti-oxidation effect on the weldment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-station high-frequency brazing machine, comprising a supporting mechanism and a positioning mechanism arranged on the supporting mechanism, a ventilation mechanism being arranged below the positioning mechanism, the supporting mechanism comprising a machine platform and side rails fixed on the machine platform, the side rails being arranged vertically, the positioning mechanism comprising an upper seat plate, a cylinder mounted on the upper seat plate and an induction coil arranged below the cylinder, the output end of the cylinder being fixedly connected to an inner sliding plate, the inner sliding plate being in contact with the inner wall of the upper seat plate, so that the inner sliding plate can slide smoothly in the upper seat plate, and the inner sliding plate being fixedly connected to a storage seat, the induction coil being fixed to the bottom of the storage seat, the ventilation mechanism comprising a fixed seat, a movable seat arranged on the fixed seat and a ventilation assembly arranged on the movable seat, a first guide rod being slidably connected to the fixed seat, a slide being fixed on the first guide rod, the movable seat being fixed to the upper end surface of the slide, a second guide rod being slidably connected to the movable seat, a mounting platform being fixed on the second guide rod, and the ventilation assembly being fixed above the mounting platform.

[0006] Preferably, two groups of positioning mechanisms and two groups of ventilation mechanisms are provided, and the two groups of positioning mechanisms are parallel to each other, thereby realizing double-station brazing.

[0007] Preferably, the positioning mechanism further includes a protective plate, which is fixed to the side railing and arranged on the outer side of the upper seat plate; and is used to shield and protect the upper seat plate and the structure thereon.

[0008] Preferably, the first guide rod is fixedly connected to the end away from the slide with a first operating handle, and the slide is slidably set on the fixed seat; when the first operating handle pulls the first guide rod, the slide can be driven to move horizontally on the fixed seat to adjust the position of the ventilation assembly from one direction.

[0009] Preferably, a second operating handle is fixedly connected to the end of the second guide rod away from the mounting platform, and the mounting platform is slidably set on the movable seat; when the second operating handle pulls the second guide rod, the mounting platform can be driven to move horizontally on the movable seat to adjust the position of the ventilation component from another direction.

[0010] Preferably, the ventilation assembly includes a receiving tube, an external air pipe fixedly connected to the outside of the receiving tube, and a nozzle arranged on the upper end surface of the receiving tube, and the receiving tube is fixed to the upper end surface of the mounting platform.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a fixed seat and a movable seat under the ventilation assembly, and can adjust the position of the ventilation assembly from two different directions by operating the first operating handle and the second operating handle, so that the ventilation assembly can be moved in real time during actual work, thereby changing the position of the nozzle in real time, so that the nitrogen released by the nozzle can be more dispersed, thereby expanding the position of the nitrogen distribution, facilitating the anti-oxidation of the inner wall of the weldment in a larger range, and having a better anti-oxidation effect on the weldment.
