Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, in particular to a thread rolling machine for processing building anchor bolts. Background Art

[0002] Anchor bolts, also known as bolts, are a type of fastener consisting of a head and a screw. They need to be used in conjunction with nuts to fasten two parts with through holes. Anchor bolts need to be threaded by a thread rolling machine, and a thread rolling machine is a multifunctional cold extrusion forming machine. The thread rolling machine can perform thread, straight grain, and twill rolling on workpieces in a cold state within its rolling force range; rolling of spur teeth, helical teeth, and helical spline gears; straightening, diameter reduction, rolling and various forming rolling.

[0003] A common thread rolling machine consists of a chuck, a thread rolling fixture and a cooling mechanism. When working, the anchor workpiece is clamped by the chuck and driven to rotate, so that the workpiece surface can be thread rolled through the thread rolling fixtures on the left and right sides. However, this method requires the workpiece surface to be sprayed with coolant during thread rolling to prevent the workpiece surface from affecting the processing quality due to excessive temperature. The coolant of the thread rolling machine is transmitted through a retractable and adjustable hose and sprayed out through a nozzle.

[0004] However, in this method, since the hose can only change its angle or position when the external force is actively adjusted, and the position of the nozzle remains unchanged during the thread rolling process, it always sprays vertically on the workpiece surface. This method not only leads to a small coverage area of ​​the coolant, but also fails to flush the metal debris accumulated on the workpiece surface, which not only reduces the cooling quality, but also easily causes the debris to accumulate on the workpiece surface, affecting the processing accuracy and failing to meet the working requirements of the thread rolling machine. Therefore, a thread rolling machine for building anchor processing is proposed. Utility Model Content
