Double-ended studs are a relatively common type of studs in fasteners and play a very important role in many places.

Main applications of double – ended studs

1, in the main body of large equipment, need to install the accessories, such as sight glasses, mechanical seal, deceleration machine frame, etc., use of the double end studs at this moment, one end of the screw in the main body, at the other end after installed accessories carry nut, because the attachment is often removed, directly using stud connecting the subject and the attachment, the main screw teeth over time will wear or damage, and the use of double end studs replacement will be very convenient.

2. When the thickness of the connecting body is large and the length of the stud is very long, the double-headed stud will be used.

In the actual work, the external load has vibration, change, material high temperature creep and so on will cause the reduction of friction force, the positive pressure in the thread pair disappears in a moment, the friction force is zero, so that the thread connection is loose, such as the repeated action, the thread connection will relax and fail.Therefore, it is necessary to prevent loose, otherwise it will affect the normal work and cause accidents.

Double – headed stud processing

The processing of double-headed studs mainly has the following steps:

First, the material needs to be pulled out, and then the material is pulled out by a drawing machine.After this process, the next process can be performed, and the next process is to use a cutter to pull it out.

The second process is completed by cutting straight long wood into the length required by the customer.

Finally, the cut short material is placed on the wire rolling machine and rolled out of the line.Ordinary double-headed double-headed studs are processed here, but other processes are required if other requirements are required.
