Tire shredder blade processing process standards and steps

The tire shredder blade should be strictly in accordance with the processing flow and standards, otherwise it will directly affect the service life of the tire shredder blade.

Tire shredder blade processing steps and standards：

1. Selection of raw materials

Shredder blades generally use Cr12mov, w6mo5cr4v2, w18cr4vSKH, M2 and other types of steel. The better quality is generally selected from Japan SKD11 steel. The shredder blades produced by this steel processing are not only wear-resistant, but also not easy to collapse and shred. The effect is not bad.

If it is used to shred rubber, fiber, paper and other materials, 9CrSi alloy tool steel is generally used. The shredder blade produced by this material is not only very hard, but also has high brittleness and wear resistance. Not bad.

In short, the choice of raw materials depends on the type of shredder.

2.Blank forging

According to the shredder blade drawing, the steel is cut off. Generally, a laser cutting machine is used for cutting, which is not only accurate, but also has a smooth edge and is well handled in the later stage.

         Subsequently, the rough material is forged, and the blank material is inspected and inspected during the forging process, and the crack or unqualified rough material is found to be rejected, and the unqualified rough material is recovered, and the processing should not be continued.

3.tempering

The forged raw material is tempered and subjected to preliminary heat treatment. Generally, the tempering temperature is not high, and the purpose of the tempering is mainly to convert the raw material into a sorbite.

4.Initial processing

For the tempered shredder blade blank material, the raw material is forged, and the rough material is forged to remove the surface impurities. The blank material should be kept as flat as possible to avoid increasing the amount of work. The initially processed blank is prepared for heat treatment.

5. Heat treatment

The shredder blade blank that has been initially processed is heat treated.The main purpose is to improve the mechanical properties of the shredder blade, and to rapidly cool it after heating at a high temperature to change the steel material into martensite.

6.Surface grinding

Surface grinding of the tire shredder blades that have been treated.

7. Wire cutting

During the wire cutting process, the wire should not be too fast. It should be perpendicular to the plane. When the inner hole is cut, it should be processed according to the dimensions provided by the drawings to avoid post-use and affect the installation of the equipment.

8. Fine grinding

Fine grinding is a process before the end of the shredder blade processing process, mainly for polishing and processing the shredder blade, and then performing hardness testing. After the test is passed, the wire can be taken offline and then packaged.

The above is the detailed process and introduction of the shredder blade processing production process, each process directly affects the quality and service life of the shredder blade, so it is necessary to follow the relevant processing technology standards and precautions.

Yuxi mechanical tire shredder tool is strictly in accordance with the process, using SKD11 high rigidity forging, good crushing effect and long service life.
