The compact fully automatic hydraulic diameter‑reduction machine utilizes hydraulic technology to feed round steel, deformed reinforcing bars, and other components requiring diameter reduction into specialized dies, where cold‑shrinkage and compressive forming are performed. This process significantly increases the material’s density, thereby enhancing its compressive strength, while maintaining its ductility and impact toughness. As a result, the strength of the threaded portion matches that of the shank, addressing the issue of reduced pressure resistance and impact toughness caused by lathe‑induced surface peeling. The compact fully automatic hydraulic diameter‑reduction machine is ideally suited for processing large‑diameter round steel, anchor bolts, double‑ended structural bolts, high‑speed bridge bolts, as well as for manufacturing mining bolts, anchoring bolts, and long‑rod bolts. It can simultaneously reduce the material to the desired rolled diameter, increasing both its density and length, and improving the tensile strength of anchor rods. It serves as an effective alternative to traditional lathe‑based peeling processes.

Maintenance of a Small Fully Automatic Hydraulic Pipe Reducer

1. During operation, the small fully automatic hydraulic tube-expanding machine requires regular inspection, maintenance, and servicing.

2. Maintenance is required every 5,000 operating hours.

3. Regularly check all fasteners for looseness.

4. If any unusual noises occur during operation of the small fully automatic hydraulic tube-expanding machine, stop the machine immediately and resume operation only after the fault has been rectified.

5. If the die has been in service for an extended period, exhibits severe wear, bends after diameter reduction, or if the reduced diameter exceeds the specified tolerance, it should be replaced promptly.

Precautions for using a small fully automatic hydraulic tube-expanding machine:

1. Due to humidity fluctuations, condensation may form on the contactor; measures must be taken to prevent short circuits between its phases, and the surfaces of the iron core and magnetic poles should be cleaned to remove any contaminants.

2. Clean debris from the small fully automatic hydraulic compression‑expansion machine, paying particular attention to the area between the incoming and outgoing leads to prevent phase-to-phase short circuits. At the same time, remove any dirt or contaminants from the surface of the iron core’s magnetic poles.

3. When the contacts are found to be severely worn and no longer usable, they should be promptly replaced with new contacts or a contactor of the same model.

How to operate a small fully automatic hydraulic swaging machine after work hours

1. The electrical enclosure must be installed in a well-ventilated location to prevent operation in environments containing dust and corrosive gases.

2. Do not add or modify PC input and output terminals without authorization.

3. When replacing the machine tool’s power supply, it is necessary to identify the motor’s direction of rotation from the outset.

4. The small fully automatic hydraulic tube-expanding machine shall be kept clean; special attention must be paid to ensure that no foreign objects are present in the sliding grooves of the clamping blocks, slides, and other components.

5. Regularly lubricate the chain and other sliding components.

6. During cleaning and maintenance of the small fully automatic hydraulic tube-expanding machine, the power supply must be disconnected.

7. Pre‑startup preparations: Verify that the oil level in the reservoir meets the specified mark; lubricate all sliding bearings; start the reduction gear and confirm that the motor rotates smoothly; inspect the oil pump for unusual noises; after starting the small fully automatic hydraulic diameter‑reducing machine, check the hydraulic system for any oil leaks.

8. Pressure Regulation: Use a solenoid safety valve to regulate pressure, ensuring that the system pressure reaches the required operating pressure, typically not exceeding

9. Mold Adjustment: The mold assembly requires alignment between the mold and the clamping block; the clamping block can be adjusted using bolts. For small fully automatic hydraulic diameter‑reducing machines, align the booster block with the mold—this booster block is adjustable. Align the mandrel with the mold, loosen the mandrel frame bolts, make the necessary adjustments, and then tighten the bolts.
