Problems solved by technology

[0006] Even though H13 steel has good heat resistance, but because this kind of steel is expensive, and changing the cylinder ring die will seriously affect the production efficiency, therefore, increasing the bottle passing capacity is still a very valuable research topic
[0007] Conventional methods include quenching, carburizing, nitriding, etc., but the effects of these methods are very limited, because the working environment of the steel cylinder ring die is a high temperature environment, and the traditional quenching enters the annealing state under the high temperature environment
In addition, for the process of carburizing, the infiltration of too much carbon will reduce the toughness of the cylinder ring die

Embodiment 1

[0035] The inventive method is used for strengthening the method step of H13 steel cylinder ring die as follows:

[0036] (1) Turn the working surface of the steel cylinder ring die to be processed flat with an ordinary lathe, and then install the turned steel cylinder ring die on the machine tool, the axis of which is along the horizontal direction and can rotate around the axis;

[0037] (2) Clean the working surface of the cylinder ring die with alcohol or acetone until the working surface is free of oil and clean;

[0038] (3) Use anhydrous alcohol to mix the laser alloy powder and phenolic resin into a paste-like alloy coating, dip the coating with a soft brush, and brush it evenly on the working surface with a coating thickness of 0.12mm, and let it dry dry or dry, the laser alloy powder is composed of tungsten carbide powder, boron carbide powder, molybdenum powder, chromium powder and nickel powder, the weight ratio is tungsten carbide powder: boron carbide powder: mol...

Abstract

The invention belongs to the technical field of laser alloying processing materials and application of the materials, and particularly discloses laser alloying powder and application of the laser alloying powder in steel cylinder circular mould laser surface alloying. The laser alloying powder and the application are suitable for a steel cylinder circular mould used in a punching and pushing type steel cylinder production line. The laser alloying powder is composed of tungsten carbide powder, boron carbide powder, molybdenum powder, chromium powder and nickel powder. The application of the laser alloying powder in steel cylinder circular mould laser surface alloying comprises the following steps that A, the work face of the steel cylinder circular mould to be treated is turned to be flat and cleaned; B, alloy powder and phenolic resin are mixed to be starchiness alloying coating through anhydrous alcohol, the starchiness alloying coating is evenly brushed on the work face, and airing or blow-drying is carried out; C, the whole work face is scanned through a laser beam in a continuous and lap-joint mode, and laser surface alloying treatment is completed. The treated steel cylinder circular mould does not need later machining, and can be used by being directly mounted on the punching and pushing type steel cylinder production line. The method is simple and easy to implement, and the service life of the steel cylinder circular mould after laser alloying treatment is prolonged by more than two times.

Description

technical field [0001] The invention relates to the technical field of laser alloying processing materials and applications thereof, in particular to a laser alloying powder and its application in laser surface alloying of a steel cylinder ring die, which is suitable for a steel cylinder ring die used in a punching and drawing steel cylinder production line. Background technique [0002] For the production line of punching and drawing steel gas cylinders, its production efficiency mainly depends on the performance of the mold used in the production of gas cylinders - the steel cylinder ring die. How to improve the red hardness of the steel cylinder ring die, prolong the service time of the steel cylinder ring die, and thus increase the bottle passing capacity are the key factors to increase the output of steel cylinders. [0003] The bottle passing capacity of the steel cylinder ring die refers to the number of steel cylinders that can be produced by a new steel cylinder rin...
