Excavator crusher bucket making process and material selection

Everyone has seen or used an excavator bucket, so how is an excavator crusher bucket made? Why is it so strong, and what material is it made of?

The first is cutting
Cutting is to cut and shape the steel plate used to make the excavator bucket. Generally, Q345B steel plate and HQ60 steel plate are used for the excavator bucket. Now, more and more manufacturers are starting to use wear-resistant steel plates or Swedish hardox steel plates as the main material of buckets. After the material arrives at the factory, flame plasma cutting is usually used. After the material is cut, it is pressed into a certain shape using a forging press.

Followed by earboard team
Ear plate team refers to the combination of cut and forged steel plates according to the requirements of the drawing to form the shape of the ear plate. According to different excavator models, the assembly drawings are different, which is related to whether the bucket is suitable for the excavator. After the ear plate is assembled according to the drawing, it must be sent to the welding area and welded on the welding positioner, which can improve the accuracy and reduce the deformation.

Then finishing
After welding, the ear plate will be finished on the boring machine to make the ear plate hole more suitable. After that, the bucket is installed according to the mold and the ear plate group. Different types of excavator buckets have different mold sizes. After rough welding, the assembled bucket is placed on the welding positioner and welded to ensure the quality of welding.

Finally, it is painted
After welding, the bucket also needs to be shot blasted to remove the oxide scale on the surface and eliminate welding internal stress. After the shot blasting, the bucket will become smooth and tidy. The finished bucket is sent to the painting workshop, and after leveling by putty, primer coating, topcoat coating, the beautiful finished bucket is thus produced.
