Problems solved by technology

[0008] Although the above-mentioned methods can draw patterns on the surface of the metal workpiece, they will cause damage to the surface of the metal workpiece to varying degrees, while the method of spraying and coating adds a completely different convex-concave structure on the substrate, thus changing the substrate itself.

Embodiment 1

[0035] Embodiment 1 of the method of the present invention comprises the following steps:

[0036] (1) According to the required drawing pattern, use a sandblasting machine to blast the patterned parts on the surface of the decarburized and annealed oriented silicon steel workpiece, and then apply a release agent on the surface of the workpiece.

[0037] The above annealed oriented silicon steel workpiece is a decarburized annealed oriented silicon steel workpiece.

[0038] The weight percentage ratio of each component of the release agent is: MgO 5%, TiO 2 5%, and the rest is deionized water. The thickness of the release agent coating is 0.5 μm.

[0039] Sandblasting is sandblasting with corundum. The sandblasting machine is mainly composed of a gas cylinder, a sand storage box, a nozzle and a workpiece moving platform. It uses compressed air or inert gas to drive the emery to the surface of the workpiece, and the emery passes through the sand storage box. To the sandblas...

Embodiment 3

[0050] Embodiment 3 of the physical method for drawing patterns on the surface of an oriented silicon steel workpiece according to the present invention is a physical method for drawing a pattern on the surface of a high magnetic induction oriented silicon steel workpiece, which includes the following steps:

[0051] (1) A step of sandblasting the surface of the annealed grain-oriented silicon steel workpiece according to the required drawing pattern.

[0052] Specifically: direct sandblasting on the patterned parts on the surface of the workpiece. The sandblasting is made of corundum, the pressure of the nitrogen cylinder is 0.3Mpa, the distance between the nozzle and the sample is 40mm, and the particle size of the corundum is 20 mesh. Then apply a release agent, the ratio of the release agent is the usual coating in this field, and the thickness of the coating is 0.1 μm.

[0053] The above annealed oriented silicon steel workpiece is an oriented silicon steel workpiece subj...

Abstract

The physical way of drawing on the silicon steel comprises the sand blasting on the surface of the silicon steel after annealing, annealing, acid rinsing. It is based on the grain size difference of two times crystalline to form the required pattern that will be shown on the designated surface without causing any damage to the silicon steel.

Description

technical field [0001] The invention relates to a method for drawing patterns (such as pictures, images, characters, etc.) on the surface of metal workpieces, especially a method for drawing patterns on the surface of oriented silicon steel workpieces. Background technique [0002] At present, there are usually two types of methods for drawing required patterns on the surface of metal workpieces, one is mechanical methods (such as sandblasting, laser, mechanical engraving, etc.), and the other is chemical corrosion methods. [0003] In recent years, there have been spraying and coating technology, but these technologies obviously add completely different organizations to the substrate by physical and chemical methods. [0004] Chemical corrosion method: as disclosed in CN86108399, a stainless steel product printing decorative pattern corrosion technology, this method transfers the printed film to the surface of stainless steel, and after corrosion and alkali treatment, patte...
