We all know Large thread-rolling machine It is a versatile cold-extrusion forming machine tool. Within its rolling‑pressure range, it can perform thread rolling, straight‑groove rolling, and helical‑groove rolling on workpieces in the cold state. By switching the selector switch to different positions, users can choose among automatic rolling, pedal‑controlled rolling, and manual operation. Large thread-rolling machine Do you really understand the two modes and the operational procedures?

of the large thread-rolling machine An introduction to the two operating modes is as follows:

1. Automatic cycling mode: Start the hydraulic motor, set the selector switch to the automatic position, and adjust the automatic advance time and the back‑stop time according to the hydraulic pressure. At this point, the sliding carriage advances under the hydraulic pressure controlled by the advance‑time relay, while it performs a back‑stop motion under the control of the back‑stop‑time relay.

2. Foot‑pedal cycling mode: Plug in the foot‑pedal connector to disable the time relay; press the switch with your foot to advance the slide carriage under hydraulic pressure. Once the working stroke is completed, lift your foot, and the slide carriage will retract hydraulically.

Now let’s take a look at the operation. Large thread-rolling machine Some points to keep in mind at the time.

1. Installation Large thread-rolling machine When using the thread‑rolling wheel, thoroughly clean the base of the thread‑rolling spindle. During installation and removal, first detach the spindle support bracket, mount the thread‑rolling wheel onto the spindle, and use adjusting shims to position the wheel at the desired axial location. The end faces of the two thread‑rolling wheels should be adjusted as closely as possible to a horizontal plane. The bearings between the thread‑rolling wheel and its support bracket are secured with shims to prevent axial movement of the wheel.

2. The support block is mounted on the support base, of the large thread-rolling machine The top is welded from cemented carbide. Loosen the fastening bolts of the support block, add or remove shims at the base of the block to adjust its height, and then tighten the bolts. The height of the support block plays a critical role during rolling compression.

3. The width of the support block shall be such that, during rolling, the roller does not come into contact with the support block. For workpieces with diameters of M10 or less, the width should be close to the allowable value. For workpieces with diameters greater than M10, Large thread-rolling machine The width at the top of the support block may be relatively large, but it need not exceed 18 mm.

Large thread-rolling machine It is primarily used for upsetting ribbed reinforcing bars in construction projects and serves as a critical piece of equipment for achieving reliable rebar splicing. Designed for rebar‑splicing applications, it ensures high connection quality by compressing the threaded ends of construction steel bars to form a thickened upset section, thereby increasing the bar’s diameter and enhancing its tensile strength. The machine is easy to operate, fast, and delivers superior processing quality. It is widely employed in major infrastructure projects, including building construction, road and bridge works, high-speed railways, subways, tunnels, and power stations with stringent performance requirements. . Large thread-rolling machine It is free of pollution and produces no open flame, allowing processing anytime, anywhere, thereby shortening the construction schedule—every minute counts.
