Embodiment

[0035] Example: see figure 1 , figure 2 .

[0036] A spray surface treatment process, comprising the following steps,

[0037] Determining the sputtering area of ​​the base metal substrate can be selectively sprayed, that is, any area on the surface of the base metal substrate can be selected arbitrarily, which can save cycle and cost;

[0038] Polishing and repair welding of the base metal matrix is ​​convenient to improve the effect after spraying treatment and achieve the expected purpose.

[0039] Degreasing treatment.

[0040] The purpose of sandblasting is to provide a favorable basis for the combination of the film and the base material. Sand blasting uses compressed air as the power to form a high-speed jet beam to spray the spray material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be treated at high speed, so that the outer surface of the workpiece surface looks or When the shape changes, due to th...

Abstract

The invention relates to a workpiece surface treatment technology in the field of stamping molds, and specifically relates to a meltallizing surface treatment process. The meltallizing surface treatment process comprises the following procedures: determining the meltallizing area of a base material matrix; carrying out polishing and repair welding on the base material matrix; degreasing; carryingout sand blasting treatment; carrying out meltallizing treatment on the strained part and the part around an R corner; and polishing the meltallized workpiece to control the surface roughness below Ra0.8. By using the meltallizing surface treatment process, the meltallizing treatment can be optionally carried out, namely the meltallizing treatment can be optionally carried out on any area on the surface of the base material matrix, thus saving treatment cost and period; the meltallizing treatment effect can be conveniently improved through the repairing treatments of the base material matrix before the meltallizing treatment, such as polishing, repair welding and the like; a favorable basis is provided for the combination of a coating film and the base material through the sand blasting treatment before the meltallizing treatment; and the surface finish quality of the mold and the product quality are improved by polishing the meltallized part after the meltallizing treatment.

Description

technical field [0001] The invention relates to a workpiece surface treatment technology in the field of stamping dies, in particular to a spray surface treatment process. Background technique [0002] With the development of production technology and the improvement of technical level, in the field of stamping, people have high requirements for the appearance quality of stamping parts. For example, in the automobile industry, people have higher requirements for the appearance quality of automobiles, and the original quality requirements for automobile surface coverings can no longer fully meet the needs of the market. [0003] Strain is the main factor affecting stamping production. The previous TD treatment, brush plating and other processes can no longer meet the current production needs. In order to solve such problems, after repeated demonstrations, a new process-melt spray, also known as thermal spraying, was introduced. The basic principle is to heat and melt the mat...
