Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt support, in particular to an anchor bolt support device for an anchor bolt thread rolling machine. Background Art

[0002] Anchor bolts refer to the general term for all rear anchoring components, with a wide range. According to different raw materials, they are divided into metal anchor bolts and non-metallic anchor bolts. According to different anchoring mechanisms, they are divided into expansion anchor bolts, expansion anchor bolts, bonding anchor bolts, etc. In the construction of nuclear power plants, anchor bolts are widely used. Anchor bolts have high strength and corrosion resistance, can work stably for a long time in harsh environments, and also have lighter seismic resistance, which can effectively reduce the impact on nuclear power plants and improve the disaster resistance of nuclear power plants.

[0003] After the anchor bolt is produced, a thread rolling machine is usually used to perform thread rolling on its surface. During the thread rolling process, the anchor bolt is placed on a support plate, and the thread rolling machine drives the anchor bolt to move forward on the support plate, thereby performing thread processing on the surface of the anchor bolt. However, when the anchor bolt moves on the support plate, the circumferential surface of the anchor bolt may rub against the surface of the support plate, which may cause wear on the outer surface of the anchor bolt and affect the subsequent thread rolling.

[0004] A search was conducted to investigate the above-mentioned problem and found that in the currently disclosed prior art, there is an anchor bolt support device for an anchor bolt thread rolling machine proposed in publication number CN220515322U. The device installs a support wheel below the thread rolling wheel. When the anchor bolt is threaded, the anchor bolt is placed on the support wheel. When the anchor bolt moves forward, it has rolling friction with the support wheel, thereby reducing the damage caused by friction. However, if the anchor bolt is short, after the front section of the anchor bolt is threaded, the threaded section may not have separated from the support wheel, causing friction between the threaded section and the support wheel, so that the surface of the support wheel damages the edge of the thread when the anchor bolt moves forward. Utility Model Content

[0005] The utility model provides an anchor bolt supporting device of an anchor bolt thread rolling machine, which solves the problem in the related art that when the anchor bolt is thread rolled, the thread-rolled part may contact the supporting plate and the supporting wheel when the anchor bolt moves, thereby causing damage to the supporting plate and the supporting wheel.
