Problems solved by technology
At present, bolts are usually made by casting first, and then the bolts are casted, and then the threads can be processed on the bolts by rolling and turning. Because the turning method is complicated and inefficient, it is seldom used. Currently, it is used more More is to roll out the thread by rolling
However, due to different usage scenarios, a certain distance of unthreaded rod needs to be reserved on the bolt rod. At the same time, because the length of the bolt rod is too long, when the bolt rod is not positioned and clamped, when the rolling roller contacts the bolt rod, it will cause The tail of the bolt shank shakes to a certain extent, which causes the center of the front and rear of the bolt shank to not be in the same circle center, causing the whole bolt shank to deflect to a certain extent, reducing the quality of the bolt

Abstract
The invention provides a rolling production device of a shafting CrNi bolt and a rolling machining process of the shafting 30CrNi3 bolt, and relates to the technical field of bolt machining. The rolling production device comprises a bolt, a base, a first rolling roller, a second rolling roller, two transverse moving mechanisms, two box bodies and two clamping mechanisms, wherein the two ends of the first rolling roller are pivoted to the upper portion of the base, the two transverse moving mechanisms are arranged on the two sides of the base correspondingly, the two ends of the second rolling roller are pivoted to the two transverse moving mechanisms respectively, the two box bodies are located on the two sides of the base respectively and located between the first rolling roller and the second rolling roller, and the two clamping mechanisms are arranged in the two box bodies respectively and used for clamping the tail of bolt. According to the device, the tail of the bolt can be positioned and clamped when the bolt is machined, and the bolt can be deburred, so the working efficiency of a user is improved.
Description
technical field [0001] The invention relates to the technical field of bolt processing, in particular to a rolling production device for shafting 30CrNi3 bolts and a processing technology thereof. Background technique [0002] At present, bolts are the most common fastening method in daily life, and at the same time, higher requirements are put forward for bolts, and it is necessary to make the manufactured bolts achieve better fit. At present, bolts are usually made by casting first, and then the bolts are casted, and then the threads can be processed on the bolts by rolling and turning. Because the turning method is complicated and inefficient, it is seldom used. Currently, it is used more More is to roll out the thread by rolling. However, due to different usage scenarios, a certain distance of unthreaded rod needs to be reserved on the bolt rod. At the same time, because the length of the bolt rod is too long, when the bolt rod is not positioned and clamped, when the ro...
