Bolts are used for connection or fastening in machinery engine parts or building components, and they are usually classified as fasteners when fixed in mechanical parts. In most cases, bolts are manufactured according to relevant national standards or international standards, so in the operation and circulation, bolts will be classified as standard parts together with other parts which are also produced according to mandatory standards. Bolts, screws and nuts are commonly referred to as screws in many areas or non-professional lectures.
The difference between bolt and screw lies in two aspects: first, in shape, the stud part of bolt is strictly required to be cylindrical for installing nut, but the stud part of screw is sometimes conical or even with center; On the other hand, using function, the screw is screwed into the target material instead of the nut. In many mini excavator parts, bolts work alone and are directly screwed into holes with pre-drilled threads without matching nuts. At this time, bolts are classified as screws functionally.
There are many kinds of bolts in the excavator crusher bucket industry, but most of them are distinguished from their studs and bolt heads. The bolt heads are divided into hexagon head bolts, square head bolts, semicircular head bolts, countersunk head bolts, perforated bolts, T-head bolts, hook head (anchor) bolts, etc. Expansion bolts are derived from bolts according to the attached expansion parts. According to the materials used in production and manufacturing accuracy, bolts with high strength, high precision and locking bolts can be derived.
We may not notice a small bolt, but the small bolt plays a great role in excavator spare parts for heavy duty machinery. This article tells us why bolts should be installed on the cutting edge of excavator bucket.
If bolts are not used, there will be a lot of troubles when the mini excavator buckets are replaced after it has been used for a period of time, and even it needs to be cut off or repaired by using a welder. However, if there are bolts at the cutting edge of the excavator grapple bucket, it is only necessary to simply remove the bolts and replace them with a new one, so that the machine can resume working in a short time, saving more time for people and facilitating the maintenance of the excavator screening bucket.
If double-sided and super heavy HB500 grade steel bolts are used, more replacement time will be saved.
If bolts are installed at the cutting edge, the length of bolts will produce extra length, which will increase the excavator tilt bucket capacity and improve the productivity of the machine.
As the length of the bolt extends the edge length of the bucket, it will reduce the wear of the bottom and reduce the work of replacing the fixed cutting edge. Moreover, the bolt increases the thickness of the cutting edge, which means that the resistance and wear of the excavator rock bucket are reduced.
Because the bolt increases the thickness of the bucket edge, it makes the ditch cleaning bucket very strong and durable.
