Product Manual for YD06-008 12-Tonne Hydraulic Floor Press (12TONNE HYDRAULIC FLOOR PRESS)

I. Product Specifications

II. Product Details

III. Application Scenarios

1. Heavy Metal Processing Scenario: Suitable for bending and pressing operations of thick steel plates and alloy plates with a thickness of 15-25 mm. For example, in heavy machinery factories, the 12-tonne pressure can be used to press thick steel plates into specific shapes of mechanical casings and equipment brackets, or to shape forged metal blanks. The multi-position worktable adapts to the processing needs of workpieces of different thicknesses.
2. Heavy Machinery Maintenance Scenario: Used for the maintenance of parts of heavy equipment such as construction machinery and mining machinery, such as the disassembly and press-fitting of large bearings and bushings. In mining machinery maintenance stations, the hydraulic hand pump can be used to control the ram to press out worn large bearings from shafts or accurately press new bearings into installation positions, avoiding component damage caused by manual operation.
3. Automotive Heavy Component Maintenance Scenario: Applied to the maintenance and processing of heavy automotive components such as gearboxes and drive axles. In auto repair shops, it can straighten deformed gearbox housings and drive axle housings, or assist in disassembling tightly fitted gear shafts and differential bearings. The accurate pressure gauge is used to control pressure, preventing damage to precision components due to overpressure.
4. Large Workpiece Assembly Auxiliary Scenario: Used for the assembly and alignment of components such as racks and bases of large equipment (such as machine tools and printing machines). In equipment manufacturing plants, the equipment can be used to align misaligned rack components and apply pressure to fix them, facilitating subsequent bolt connection, ensuring the overall precision of the assembled equipment, and reducing vibration and noise during operation.

IV. Frequently Asked Questions (FAQs)

(I) What to Do If the Ram Descends Too Fast and Is Difficult to Control When Operating the Hand Pump?

1. First, check if the oil return valve of the hand pump is loose. An overly loose oil return valve will cause hydraulic oil to flow back too quickly. Use a wrench to slightly adjust the oil return valve clockwise until the ram descends at a stable speed. Be careful not to tighten it too much to avoid the ram being unable to descend.
2. Check if the viscosity of the hydraulic oil is too low. If the type of hydraulic oil used does not meet the requirements (e.g., using 32# instead of 46#), the fluidity of the oil will be too strong. Replace it with the recommended 46# anti-wear hydraulic oil to ensure the oil viscosity meets the equipment's needs.
3. If the above operations are ineffective, the internal sealing ring of the hand pump may be aged. Disassemble the hand pump and replace the sealing ring with one of the same specifications. After replacement, apply hydraulic oil for lubrication to prevent oil leakage due to poor sealing.

(II) How to Fix the Worktable Sliding Down on Its Own After Adjusting the Gear?

1. Check if the worktable locking bolts are tightened. Use a wrench to tighten the locking bolts one by one. If the bolts are stripped, replace them with high-strength bolts of the same model to avoid failure to fix due to insufficient bolt strength.
2. Check the fit between the worktable guide rail and the positioning groove. If there is oil or impurities on the guide rail surface, wipe it clean with a cloth dipped in detergent. If the positioning groove is excessively worn, insert a thin metal sheet into the positioning groove to increase the fit tightness.
3. Check if the worktable support spring is aged. If the spring elasticity is insufficient, replace it with a new spring to ensure the spring provides sufficient support force for the worktable and prevents sliding.

(III) What Causes Normal Pressure Gauge Reading But Insufficient Actual Pressure During Equipment Operation?

1. Check if there is hidden leakage in the hydraulic pipeline, focusing on whether there is slight oil seepage at the pipeline joints. If there is oil seepage, replace the joint gasket and re-tighten it. Hidden leakage will cause actual pressure loss, which the pressure gauge cannot reflect in a timely manner due to its position.
2. Check the fit clearance between the ram and the oil cylinder. If the clearance is too large, it will cause internal leakage of hydraulic oil. Disassemble the ram and replace the oil cylinder sealing ring to reduce internal leakage.
3. Confirm whether the pressure gauge is calibrated. If the pressure gauge has not been calibrated for a long time, there may be reading deviation. Re-calibrate the equipment pressure gauge with a standard pressure gauge to ensure accurate reading.

(IV) How to Solve Difficult Hand Pump Pressing When the Equipment Is Started After Long-Term Idleness?

1. Check if the hydraulic oil in the hydraulic oil tank is solidified or deteriorated. If the oil is solidified due to low ambient temperature, gently heat the oil tank at a low temperature (temperature not exceeding 40℃). If the oil is deteriorated, completely replace the hydraulic oil and clean the oil tank.
2. There may be air in the hand pump. Open the hydraulic oil tank cover and repeatedly press the hand pump handle to discharge the air in the pump until the pressing feel becomes lighter.
3. Check if the oil suction pipeline of the hand pump is blocked. If the oil suction filter is blocked by impurities, disassemble the filter for cleaning or replacement to ensure smooth oil suction and reduce pressing resistance.
