Problems solved by technology

However, there are many problems in the existing cutting knives, such as the characteristics of metal products are easy to rust after being placed for a long time, requiring the user to replace the cutting knives, and the Dacromet coating is made of flaky zinc powder, aluminum powder, chromium-containing The coating liquid composed of metal salt and binder is coated on the surface of the part and sintered to form a protective layer with a new structure and performance. On this basis, technicians have improved and perfected it.

Embodiment Construction

[0012] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] Examples such as figure 1 Shown, a kind of preparation method of the sprayer cutting tool that has coating, comprises the following steps, pre-treatment, removes after the oil stain, iron and scale sundry on parts cutting tool surface; In the first step, the process of pre-treatment For organic solvent, alkaline cleaning agent degreasing, shot blasting, shot blasting or sandblasting one or more combinations. Coating is to spray or impregnate the parts cutting tool with dacromet solution, and then use centrifugal drying, natural vertical flow and / or brush to remove excess dacromet treatment solution; baking is to apply dacromet on the cutting tool substrate T...

Abstract

The invention discloses a preparation method for a small harvester cutting tool with a coating. The method comprises the steps that during pre-processing, oil stains, iron and oxidation skin sundries on the surface of parts and the cutting tool are removed; during coating, a Dacromet solution is used for spraying or dipping of the parts and the cutting tool, and the residual Dacromet treating fluid is removed through centrifugal dripping, natural vertical flowing and/or brushing; during baking, the Dacromet treating fluid on the base body of the cutting tool is converted into a film layer in a mesh-belt circulating hot wind baking furnace; and then, the cutting tool is cleaned and polished.

Description

technical field [0001] The invention belongs to the technical field of agricultural tools, and in particular relates to a preparation method of a coated small harvester cutting tool. Background technique [0002] In the process of crop production, due to various reasons of cost and land constraints, producers use less agricultural machinery, and the cost of small harvesters is small, which breaks through the operational bottleneck that cannot be harvested by large harvesters in rural areas, and promotes the mechanization of harvesting operations, shortening It shortens the labor cycle and liberates people from heavy physical labor. Widely used to harvest wheat, rice, highland barley, hemp, beans and other crops. However, there are many problems in the existing cutting knives, such as the characteristics of metal products are easy to rust after being placed for a long time, requiring the user to replace the cutting knives, while the Dacromet coating is made of flaky zinc pow...
