Product Manual for 20-Ton Hydraulic Shop Press (YD06-002)

I. Product Specifications

II. Product Details

III. Application Scenarios

1. Mechanical Parts Processing Field: It can be used for press-fitting operations of parts such as bearings and bushings. By using the stable 20-ton pressure, parts are accurately pressed into the installation position, avoiding damage to parts or installation deviations caused by manual knocking. It is suitable for scenarios such as automobile maintenance and agricultural machinery parts processing.
2. Metal Material Shaping Scenario: For metal materials such as steel plates and iron plates with moderate thickness, it can complete shaping processes like bending and straightening. For example, in small hardware processing plants, the equipment can be used to bend metal plates into brackets with specific angles or straighten and repair deformed metal components to meet personalized processing needs.
3. Mold Auxiliary Operation Scenario: In the production and maintenance of small molds, this press can be used to complete the disassembly and assembly of molds. For instance, when replacing mold accessories, uniform pressure is applied by the equipment to separate tightly fitted mold parts or accurately press-fit new accessories, improving the efficiency of mold maintenance. It is suitable for the handling of small and medium-sized molds such as plastic molds and stamping molds.
4. Waste Recycling Processing Scenario: In waste recycling stations or small metal recycling enterprises, it can be used to compress metal waste. For example, scattered aluminum cans, iron sheets, etc., are pressed into compact blocks, reducing the occupation of storage space, facilitating subsequent transportation and smelting processes, and improving the economy of waste recycling.

IV. Frequently Asked Questions (FAQs)

(I) What to Do If the Equipment Has Insufficient Pressure?

1. First, check the hydraulic oil level. If the oil level is lower than the specified standard, supplement the same type of hydraulic oil to the normal range, as insufficient hydraulic oil will directly lead to a decrease in pressure output.
2. Check whether there is leakage in the hydraulic system, focusing on parts such as cylinder seals and oil pipe joints. If oil leakage is found, replace the damaged seals or tighten the joints to prevent hydraulic oil loss from affecting the pressure.
3. If the pressure is still insufficient after the above operations, the hydraulic pump may be faulty. It is recommended to contact professional maintenance personnel to inspect or replace the hydraulic pump. Do not disassemble the hydraulic pump by yourself to avoid causing more serious equipment damage.

(II) How to Deal with the Inability to Adjust the Platform Height?

1. First, check whether the adjustment mechanism is stuck by foreign objects, such as metal chips and dust. If there are any, clean the adjustment rails and transmission parts with a brush, compressed air, etc., to ensure the smooth operation of the adjustment mechanism.
2. Check the lubrication condition of the adjustment mechanism. If parts such as rails and lead screws are insufficiently lubricated, the adjustment resistance will increase. Special lubricating oil should be added to reduce part wear and frictional resistance.
3. If the adjustment is still not possible after cleaning and lubrication, the adjustment motor or transmission gear may be faulty. Disconnect the equipment power supply, contact after-sales personnel for inspection, check whether the motor operates normally and whether the gears are worn or broken, and then carry out maintenance according to the cause of the fault.

(III) What Causes Excessive Noise During Equipment Operation?

1. Check whether the hydraulic oil has deteriorated. If the hydraulic oil becomes turbid or black, it will cause abnormal noise during the operation of the hydraulic system. The hydraulic oil should be replaced with new ones, and the hydraulic oil tank should be cleaned to remove impurities.
2. Check whether the motor fixing bolts are loose. Loose motors will cause vibration noise during operation. Use a wrench to tighten the motor fixing bolts to ensure the stable operation of the motor.
3. Check the operation status of the cylinder. If the inner wall of the cylinder is worn or the seals are aged, abnormal noise will occur during the operation of the cylinder. The cylinder should be disassembled to check the condition of the inner wall, and the aged seals should be replaced or the worn inner wall of the cylinder should be repaired.

(IV) What Precautions Should Be Taken During Equipment Transportation and Installation?

1. During transportation, use a forklift or crane to place the equipment on the transport vehicle stably, ensuring that the inclination angle does not exceed 15°. At the same time, fix the equipment firmly with ropes to prevent it from shaking and colliding during transportation, which may damage the equipment parts.
2. The installation site should be a flat and hard ground to avoid shaking of the equipment during operation due to uneven ground. Before installation, a level can be used to check the flatness of the ground. If the ground is uneven, steel plates or adjustment gaskets should be laid to level the ground.
3. After the equipment is installed, check whether the power wiring is correct, and ensure that the voltage is consistent with the rated voltage of the equipment (usually 380V industrial electricity, subject to the equipment nameplate). After wiring is completed, conduct a trial power-on to check whether all buttons and indicator lights of the equipment work normally. Then carry out no-load test operation, and only after confirming that the equipment operates normally can formal operations be carried out.
