Large-bolt thread rolling technology

Abstract

The invention provides a large-bolt thread rolling technology. The technology comprises the steps that a bolt with threads required to be rolled is fixed to a bolt fixing clamp of a common thread rolling machine; the thread rolling machine is started to carry out thread rolling; after thread rolling is completed, the bolt with a half part being machined is taken out; an adjustable bolt fixing clamp is mounted on the outer side of a static thread rolling plate of the common thread rolling machine; the bolt with the half part being machined is fixed to the adjustable bolt fixing clamp on the static thread rolling plate, the position of the bolt is adjusted, and the portion with the rolled threads is fixed outside the thread rolling plate; the thread rolling machine is started to carry out thread rolling on the remaining portion of the bolt; and after the threads are rolled, the bolt is taken out, and the bolt is wiped clean. According to the technology, thread rolling can be carried out on the large bolt, and thread rolling is easy and convenient; when thread rolling is carried out on the large bolt, a large thread rolling device does not need to be purchased any more, and a user only needs to use the method. A large amount of production cost can be saved while the order of a customer is completed, and the economic benefits of an enterprise can be improved.

Description

[0001] technical field [0002] The invention relates to a thread-rolling process, in particular to a large-scale bolt thread-rolling process. Background technique [0003] Thread rubbing is a processing method in which the blank between the two washboards is rolled into a spiral groove when the two washboards move relative to each other. The thread rolling process is the most important step in making bolts. In the past, the threads on the bolts were generally completed by turning process, but the turning process is slow and the threads are relatively flat, so the effect is not good. The thread rolling process was first proposed by the navigation company , The thread rolling process, also known as the thread rolling and shrinking rod process, replaces the original turning process, which not only saves materials, reduces production costs, but also reduces labor costs, and most importantly, it makes the threads sharper and greatly improves efficiency.

The thread rolling process is the most important step in making bolts. In the past, the threads on the bolts were generally completed by turning process, but the turning process is slow and the threads are relatively flat, so the effect is not good. The thread rolling process was first proposed by the navigation company , The thread rolling process is also called the thread rolling and shrinking rod process, which replaces the original turning process, which not only saves materials, reduces production costs, but also reduces labor costs, and most importantly, it makes the threads sharper and greatly improves the efficiency

The thread rolling process is generally completed by a thread rolling machine. The bolts used today are generally relatively short, so the thread rolling machines are generally relatively small, which not only facilitates the thread rolling process, but also reduces the floor space and production materials of the thread rolling machine, saving Resources, larger bolts are still used in some fields, and some customers will customize from the manufacturer. The mechanical size required for the production of large bolts and small bolts is different. Manufacturers need to introduce large-scale thread rolling machines, which increases production costs. , and the use of large thread rolling machines is seldom, and the purchased large-scale equipment is easy to be put on hold, resulting in waste of resources
