What is Mold Repairing Machine K Advantages?

 

Low heat generation: Since the mold repairing machine K can complete the welding of the welding wire and the workpiece within tens of milliseconds, compared with argon welding, it conducts less heat to the workpiece, and the temperature of the base area outside the welding point is small, so the base will not be annealed , Discoloration, undercut and other problems, the molten pool generated by each welding pulse is less than 2mm³, so the matrix stress is also small.

High repair accuracy: Mold repairing machine K uses microcomputer chip technology, which controls the output current very accurately. Even 0.2mm welding wire can achieve a good welding repair effect.

Wide selection of materials: In addition to materials with very low melting points such as zinc and tin, workpieces made of various metal materials such as copper and aluminum can be welded.

Simple operation: Mold repairing machine K adopts the function of storing commonly used parameters and digitally displays the size of adjustment parameters. The operation is simpler than general argon arc welding machines.

High welding strength: Mold repairing machine K discharges at high frequency instantaneously, and quickly welds the welding wire to the workpiece; fully achieves metallurgical bonding.

No loss to the workpiece: low temperature, small molten pool area, fast heat dissipation, and will not affect the workpiece such as annealing deformation.

Low argon demand: Mold repairing machine K uses the principle of high-frequency pulses to form solder joints on the surface of the workpiece through the arc, so only 3/1 of the usual argon arc welding machine is needed, which saves costs!

Description

The mold repairing machine is applicable and suitable for repairing workpiece that made of various metal materials such as iron, stainless steel, expect copper, aluminum with extremely low electrical resistivity. With high repairing accuracy, the mold repairing machine is available for repairing with sheet materials without losing the original reference surface. Its repairing range is from minimum 0.03mm to maximum 0.25mm. The substrate damage of mold repairing machine is small as the heating point is small, and the substrate is not annealed and deformed. It is light and portable, easy to operate.

Mold Repairing Machine K Working Principle

 

First of all, the electric energy of Mold Repairing Machine stored in the capacitor is instantaneously released at the joint between the workpiece(which is composed of a metal material such as steel, iron, stainless steel that have a large electrical resistivity) and the supplementary material, so that they are rapidly heated and welded together to achieve the purpose of repairing the mold. Since the heat is generated in a small range of time, there is little heat generation in the workpiece substrate, so that deformation, annealing, discoloration, etc. of the workpiece are not generated.

This is a simple explanation to mold repairing machine for how it works.

How to clean the surface of the mold to be repaired by the mold repairing machine K?

If there is oil stain on the repaired area, wipe it with alcohol or acetone. The oxide film can be removed with emery cloth or whetstone. The anti-rust oil and oxide film on the repair material should also be removed by the same method.

 

How should the mold repairing machine K welding head be prepared?

Anti-rust oil and oxide film should also be removed by the same method. For deep small holes (pinpoint holes) and steep-wall holes, proper reaming should be performed first. The method is as follows: select the thickness display data at about 06-09, and use a spherical welding head (the size of the welding head can be determined according to the size of the reamed hole, generally Take the welding head from 3 to 5) and press it on the hole, step on the foot switch to melt the tip of the hole wall and turn it into an anti-spherical pit to increase the welding surface between the replenishment material and the workpiece (see the figure below). If it is a piece of small holes, you can use an electric grinder to grind the surface of about 0.1mm. For some nitrided workpieces, because there is a lot of nitrogen in the surface material of the workpiece, the high temperature during welding causes the nitrogen to expand, which will separate the surface layer of material from the main body. The usual way to solve this problem is to use an electric grinder to remove the nitrided layer, and then weld the material. Or, do not put the repair material, and use the welding head to discharge welding once, so that a part of the nitrogen in the nitride layer is volatilized and then welded, which will greatly improve the welding effect.
