The working process of the invention is analyzed:
a universal welding support for induction brazing is mainly used for mounting, fixing a welding positioning block and clamping parts to be welded, the device is required to ensure that the relative position of the components in the welding process is correct and remains unchanged, and in addition, certain pressure is provided for the welding process in the welding process, so that the welding quality is ensured. As shown in fig. 1, a support frame 18 and a support block 8 on a welding support fix an upper clamp 1 and a lower clamp 6 on the support frame 18 by using a first locking screw 2 and a second locking screw 7 respectively, a workpiece A3 to be welded and a workpiece B5 to be welded are positioned (solder and welding flux are placed in the middle) through a cavity of the lower clamp 6 or the upper clamp 1 to realize part positioning, then the support block 8 moves upwards to the center of an induction heating ring 4 while the induction heating ring 4 is electrically heated, so that the workpiece A3 to be welded and the workpiece B5 to be welded are rapidly heated, at the moment, the upper clamp 1 simultaneously presses the workpiece A3 to be welded, accurate positioning and solder gas exhausting operation of welding are realized, and the correct position and good welding seam quality of a welded component are ensured.
The design of the invention is as follows:
from the above analysis, it can be seen that the present invention, on one hand, needs to conveniently and quickly install and replace the upper fixture 1 and the lower fixture 6 to implement the processing of different components, on the other hand, needs to consider the convenience of assembling and disassembling the to-be-welded workpiece A3, the to-be-welded workpiece B5 and the welded component during the welding operation, and above all, needs to make the to-be-welded workpiece B5 move up in the center of the induction heating ring 4 to be heated quickly and effectively during the welding, and keeps the to-be-welded workpiece A3 and the to-be-welded workpiece B5 to have a certain bonding force and positioning without being damaged during the melting of the solder, according to the above conditions and most of the component characteristics requiring the induction brazing processing, designs a general induction brazing welding support as shown in fig. 1-3, firstly, the support uses the support block 8 sliding horizontally back and forth to move the to-be-welded workpiece A3 and the to-be-welded workpiece, the problem that parts are difficult to take and place in the induction heating ring 4 in a narrow space is solved, and the accurate positioning and the convenient taking and placing of the workpiece are ensured; secondly, the support adopts a cam mechanism to realize the rapid lifting of the support block 8, so that the workpiece A3 to be welded and the workpiece B5 to be welded are rapidly heated at the center of the induction heating ring 4, and meanwhile, the proper pressure is obtained between the workpiece A3 to be welded and the workpiece B5 to be welded by matching with a tension spring 19 on the support frame 18, so that the good welding seam quality is ensured; the support can weld components with different specifications only by replacing different upper clamps 1 and lower clamps 6.
In addition, since the induction brazing heating coil has thermal effect on metals in a heating range, the upper clamp 1 and the lower clamp 6 need to be made of heat-resistant non-metal materials such as graphite, heat-resistant asbestos plates or oilstones.
The assembly requirements of the invention are:
as shown in fig. 4 and 5, during the assembly process, firstly, care should be taken to ensure that the support frame 18 can still freely slide up and down without shaking after the compression screw 16 is tightened; secondly, the supporting block 8 can also slide up and down and back and forth in the whole T-shaped groove after being assembled, and a small amount of lubricating grease is filled at the upper part to keep lubrication and rust prevention when necessary.
The using method and the steps of the invention are as follows:
installing a clamp: firstly, selecting a proper welding clamp according to a workpiece to be machined, then aligning an upper clamp 1 and a lower clamp 6, respectively locking the upper clamp and the lower clamp by using a first locking screw 2 and a second locking screw 7, and then, after the workpiece is arranged, paying attention to the adjustment of the upper position and the lower position of the upper clamp 1 to proper positions to ensure that a workpiece A3 to be welded and a workpiece B5 to be welded have certain pressure when an induction heating ring 4 is positioned at a heating center, so that the clamps are initially arranged.
Installing parts to be welded: pulling the push-pull screw 23 to pull out the support block 8 on the lower clamp 6 to the outside of the induction heating ring 4, putting the to-be-welded workpiece A3 and the to-be-welded workpiece B5 into the induction heating ring 4 and ensuring correct positioning, then pushing the support block 8 to the bottom to enter the induction heating ring 4, then rotating the lifting push rod 9 to enable the support block 8 to drive the welding part of the to-be-welded workpiece A3 and the to-be-welded workpiece B5 to rise to the same horizontal height of the induction heating ring 4, and simultaneously pressing the part by the upper clamp 1, so that the to-be-welded workpiece A3 and the to-be-welded workpiece B5 are clamped.
The electric welding parameters and the heating time of the welding machine are selected to be electrified for trial welding, the welding can be carried out in batches after the welding seam quality is detected to be qualified, the welding flux is immediately powered off after the melting flow distribution of the welding flux is observed to be uniform in the welding process, the parts are prevented from being over-burnt, the lifting push rod 9 is reversed to lower the support block 8 after the welding flux is cooled, solidified and discolored, and the welded workpiece is smoothly dragged out after being lower than the induction heating ring 4.
It is worth noting that the dosage of the solder flux in the welding process should be effectively controlled, the flux solder is prevented from flowing into the lower clamp 6 to affect the positioning of the workpiece, and the supporting block 8 can be lowered only when the solder to be welded is cooled and solidified, otherwise the mutual dislocation defect of the welded workpieces is easy to occur.
The invention utilizes the induction brazing machine and combines a simple clamp for induction brazing to replace flame brazing, thereby improving the production efficiency of welding components in the relay and the contactor, reducing the production cost and consumption and shortening the period of new product development and batch processing.
