How hydraulic press works

2021-06-16 03:02:59

The hydraulic press is a device that uses hydraulic drive technology for pressure processing and can be used to perform various forging and press forming operations. For example, the forging of steel, the formation of metal structural parts, plastic products and rubber products such as suppression. Hydraulic press is one of the earliest applications of hydraulic transmission. At present, hydraulic transmission has become the main transmission form of pressure processing machinery. In heavy machinery manufacturing, aviation industry, plastics and non-ferrous metal processing industries, hydraulic presses have become important equipment.

The hydraulic transmission system of the hydraulic press is mainly based on pressure transformation. The system pressure is high, the flow rate is large and the power is large. Therefore, special attention should be paid to improving the power utilization of the prime mover and preventing shock and vibration during pressure relief to ensure safety and reliability.

According to the requirements of the pressing process, the hydraulic press can complete the basic working cycle of rapid pressure down, regenerative deceleration, pressure relief delay, pressure relief return stop (arbitrary position), and the pressure, speed, and pressure holding time can be adjusted. The ejector hydraulic cylinder is mainly used for ejecting the workpiece, and it is required to realize the actions of ejecting, retreating, and stopping. If the sheet is stretched, an auxiliary action such as lifting, stopping, and pressure return of the hydraulic cylinder is required. Sometimes the blanks need to be compacted with a blanking cylinder to prevent wrinkling around.

The hydraulic press uses the maximum pressure (tonnage) that the main actuator (master cylinder) may output as the main specification of the hydraulic press and has been serialized. The tonnage of the top material tank often uses 20% to 50% of the tonnage of the master cylinder. The top out cylinder of the extruder can use about 10% of the main tonnage. The tonnage of the edge-pressing cylinder of the double-acting drawing hydraulic press generally uses about 60% of the tonnage of the drawing cylinder.

The speed of the master cylinder is determined by the pressure processing process. Generally, in the hydraulic system directly fed by the pump, the working stroke speed does not exceed 50 mm/s, the rapid traverse speed does not exceed 300 mm/s, and the hydraulic machine retreat speed and fast forward Equal speed.

Gravity Separator

Introduction

The product processed by the gravity separator is separated into layers of different specific weight according to the [fluid bed" principle. For the grading by specific weight of products with very slight differences in size and/or weight, which cannot be separated by screening (width), aspiration (weight) or by indented cylinders (length), so the materials after processing they will have the optimal physical quality and strongest germinating power. The separator effectively removes partially eaten, immature and broken seeds to ensure maximum quality of the final product which consume the most time of masses. They may be used to separate and standardize coffee, peanuts, corn, peas, rice, wheat, sesame and Other food grains.

These Gravity Separators have a rectangular shaped deck so that the product travels a longer distance resulting in cleaner separation of light and heavy particles and the lowest percentage of middlings. The processing of the Gravity Separator is accurate and smooth where the product flows over the vibrating deck in which pressurized air is forced through causing the material to stratify according to its specific weight. In which, the heavier particles travel to the higher level and the lighter particles travel to the lower level of the deck.

To accomplish the goal of managing efficient separation by specific weight, this is necessary that the pressurized air supply needs to be accurately adjusted by having individually adjustable air fans to control the volume of air distribution at different areas of the vibrating deck. And to make sure the functioning, the table inclination, speed of eccentric motion and the feed rate can be precisely adjusted with ease and minimum of operator training.
