Hydraulic thread-rolling machine What is the working principle? Let’s take a look together below. Hydraulic thread-rolling machine Unlike threading machines, this is a machine that forms threads on workpieces using pressure; it does not cut the material. The compressive force applied to the workpiece enhances its rigidity and increases its strength. It is primarily used for solid workpieces. Thread rolling (as for reinforcing steel). Its advantages include simple operation, high energy efficiency, and high productivity. Hydraulic thread-rolling machine It mainly consists of a gas system, an electrical control cabinet, a hydraulic system, a cooling system, and roller shafts. Depending on the number of shafts, it is typically classified as either a two‑shaft or a three‑shaft roller machine. The key difference is that the two‑shaft model is more affordable but can only process solid workpieces, whereas the three‑shaft model is more expensive and capable of machining tubular components.

Hydraulic thread-rolling machine Workflow: 1. Commission the machine by powering it up as needed, filling the coolant tank with coolant, and then starting the roller to verify that the cooling system, control system, and other components are functioning properly. 2. Install rollers corresponding to the rebar diameter, and replace the appropriate washers to ensure accurate pitch. 3. Load the rebar: mount the rebar onto the centering fixture, extend it to align with the end face of the rolling head’s deburring blade at the initial position, and securely clamp the rebar. 4. Start the roller, turn the movable handle to begin rib‑removal, continue forming the thread, and once rolling is complete, press the reverse‑start button to automatically retract the tool. After finishing, clean the machine, keep it tidy and dry, and perform regular maintenance such as lubricating the roller and replacing consumable parts.

Hydraulic thread-rolling machine What is the method of use? Let’s take a look together below. (1) Pre‑processing preparations: 1. Connect the power and grounding wires as required, then switch on the power supply. The power source is a three‑phase 380 V, 50 Hz AC supply. For personal safety, use an automatic circuit breaker equipped with leakage protection. 2. Fill the coolant tank with an adequate amount of soluble coolant (do not use oil‑based coolants under any circumstances). (2) No‑load test run: 1. Turn on the power and verify that the coolant pump is operating normally. 2. Operate the control buttons to confirm that the electrical control system is functioning properly. Fully automatic three‑axis machine. Hydraulic thread-rolling machine Introduction to usage precautions. When using the fully automatic triaxial testing system… Hydraulic thread-rolling machine When doing so, you should pay attention to the following ten key points.

1. Cooling liquid Need Use water-soluble emulsifiable coolant; the use of oil-based coolants is strictly prohibited, and ordinary lubricating oil must not be used as a substitute.

2. Hydraulic thread-rolling machine should Thread rolling without cooling water is strictly prohibited.

3. The ends of the reinforcing bars to be processed Need Smooth, Need Cut the material using a reciprocating saw. In addition, at the end… Within a length of 500 mm Need It is circular, does not permit bending, and cannot be directly processed by gas cutting or a cutting machine at the lower end.

4. Hydraulic thread-rolling machine of the During initial cutting, feed the tool evenly and avoid applying excessive force to prevent chipping or breakage of the cutting edge.
