How to choose wear-resistant steel plate processing and maintenance excavator bucket
The working principle of the shovel shovel is to use the bucket fixed on the bucket, use the thrust generated by the pushing mechanism to cut the bucket into the rock, and use the power of the lifting mechanism to rotate the bucket handle around the pushing shaft.
Under the action of pushing pressure and lifting force, the bucket is filled, and then the bucket turns down, driven by the rebound mechanism, the bucket reaches the position of the transport vehicle for unloading, so that the goods can be loaded into the car.
The working device of the electric shovel excavator is divided into two structural forms of the single beam boom outside the bucket rod and the double beam boom inside the bucket rod. The structure of the outside bucket rod of the single beam moving arm is simple and the weight is light, and the structure of the outside bucket rod of the single beam moving arm is adopted.
The bucket of the electric shovel excavator is composed of the following main parts: the bucket is composed of the bucket body (the forearm of the bucket, the back of the bucket), the bottom of the bucket, the lifting beam, the bucket teeth, the pulley and the balancing wheel. In order to improve the service life of the bucket, wear-resistant steel plates are widely used as the main parts of the material. The front and back walls of the bucket are mostly made of wear-resistant steel plates and are connected with welded plungers between the front and back walls. The front wall is equipped with wear-resistant bucket teeth, which can be replaced after damage. Usually made of high-strength wear-resistant steel.
The girder is made of high manganese steel 锩 into an I-shaped structure with reinforcing ribs, and the ears are connected with the pulley and bucket body respectively. The bucket bottom can be welded with wear-resistant lining plate on the whole cast bottom plate to improve the service life, or the wear-resistant steel plate can be directly used to process the bottom plate. The bottom of the bucket with wear strips to increase strength, bucket bolt and bucket bolt rod are easy to wear parts, it is best to use wear-resistant steel processing. To improve the work of the bucket, the forearm is slightly higher than the rear wall. In order to facilitate unloading and avoid blocking the bucket with large rocks, the lower part is wider than the upper part. In order to avoid the lower forearm wear protruding forward, high strength wear-resistant steel plates are welded inside the bucket to prevent bucket wear.
In the selection of wear-resistant steel, if the budget allows, you can use more imported wear-resistant steel, such as JFE EH series wear-resistant plate, according to the hardness of the material in contact, as appropriate, JFE-EH400, JFE-EH500 and other models can meet most of the working conditions.
