Description

Technical Field

[0001] The utility model relates to the field of bolt preparation, in particular to a thread rolling device used for processing anchor bolts. Background Art

[0002] The thread rolling machine is a kind of equipment for processing the outer surface of cylindrical workpieces. Its working principle is that two identical thread rolling surfaces have the same thread shape and helix angle as the bolt thread. When the thread rolling plates move against each other, the bolt blank between the two thread rolling plates is threaded. Take the processing of bolts as an example.

[0003] For example, Chinese patent: Publication No. CN220311635U, a bolt thread rolling machine, includes an assembly plate, the left and right ends of the table plate are fixedly provided with electric slide rail devices on the inside, the electric slide rail device is engaged and contacted with a slide frame on the outside, the front and rear ends of the slide frame are fixedly provided with sleeve plates on the inside, the front and rear ends of the sleeve plates are fixedly provided with cavity boxes on the outside, a water pump device is fixedly provided inside the cavity box, a conduit is fixedly provided inside the sleeve plate, a thread rolling cavity plate is fixedly provided on the front and rear ends of the sleeve plates on the inside, a chip removal frame is fixedly provided at the bottom end of the assembly plate, a chassis is fixedly provided at the bottom end of the chip removal frame, and a negative pressure fan is fixedly provided inside the chassis.

[0004] Although the functions of positioning, thread rolling and cooling the bolts are formed by the assembly plate, table, clamping pad, slide stand, sleeve plate, cavity box, duct, chip removal frame, chassis and negative pressure fan, there is a lack of mechanism to collect waste water when cooling by water, which can easily cause waste water to fall directly on the ground and affect the surrounding environment. At the same time, after threading the bolts, waste chips will remain on the threading plate. If they are not cleaned in time, it will easily affect the quality of the next bolt threading.

[0005] Therefore, we proposed a thread rolling device for anchor bolt processing. Utility Model Content
