Mold has extremely important effects in modern industry; its quality directly determines the quality of the product. Improves the service life and accuracy of the mold; shortens the production cycle of the mold; is a skill problem that many companies urgently need to deal with; but often in the process of using the mold There are failure modes such as collapse angle, deformation, wear, and even breakage. Therefore, correction of the mold is also necessary. There are many ways to correct the mold; such as EDM, argon arc welding correction, laser surfacing, brush plating.
The argon arc welding correction uses the arc that is incinerated between the welding wire and the workpiece as a heat source; the gas sprayed from the torch nozzle keeps the arc for welding. The current argon arc welding is a common method; it can be applied to most of the primary Metal; contains carbon steel, alloy steel. Molten inert gas welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys; because of low price; widely used in mold correction welding; but the welding heat affected area is large , solder joints and other defects; currently in the fine mold repair has gradually replaced laser welding instead.
Brush plating correction brush plating technology is to choose a special DC power supply equipment, the positive pole of the power supply is connected to the pen as the anode during brush plating; the negative pole of the power supply is connected to the workpiece as the cathode during brush plating. The plated pen is generally made of high-purity fine graphite block as anode material, and the graphite block is covered with cotton and wear-resistant polyester cotton cover. During operation, the power supply component is adjusted to a suitable voltage, and the plated pen penetrating the plating solution moves back and forth on the surface of the workpiece to be corrected at a certain relative movement speed, and adheres to a certain pressure until the metal accumulation layer constituting the uniform ambition stops. . Because the plated pen and the part touched by the surface of the corrected workpiece, the metal ions in the plating solution are dispersed on the surface of the workpiece under the effect of the electric field force, and the electrons are reduced to metal atoms on the outer surface, and then the metal atoms are deposited and crystallized to form a plating layer. It is to obtain the required uniform accumulation layer on the modified plastic mold cavity working surface.
Laser surfacing laser welding is a laser beam that is concentrated by using a high-power coherent monochromatic photon stream. This welding method generally has continuous power laser welding and pulse power laser welding. The laser welding strength is not required. The vacuum is carried out; the defect is that the penetration force is not as strong as the electron beam welding. The laser can perform accurate energy control; therefore, it can complete the welding of fine equipment. It can be applied to many metals; in particular, it can handle some difficult-to-weld metals and Welding of dissimilar metals. Currently widely used for mold correction.
