63 ton four column hydraulic press with three beams

The upper, middle, and lower beams of the 63 ton four column hydraulic press are made of domestically produced high-quality steel plate Q235B. The cutting welding process has good rigidity and strength, and the crossbeam is polished to remove various welding slag and oxide layers. The connecting parts of the crossbeam are roughly and finely machined, and the surface is finely milled. The boring process ensures the accuracy of each hole shape. The T-shaped groove is milled, the chamfer is deburred, and after passing the inspection, anti rust paint is sprayed and stored.

63 ton four column hydraulic press hydraulic cylinder

1. The cylinder barrel of the four column hydraulic press is a piston type structure, and the large cylinder body is made of 45 steel parts. The front and rear ends are threaded and connected to steel plates, welded, welded, inspected, annealed, rough machined, quenched and tempered to obtain better comprehensive mechanical properties such as strength and toughness. The various components are finely machined, the inner hole is bored and left with fine machining quantity, the cylinder barrel is ground or polished, the various parts are drilled and chamfered, the inner hole is ground to meet the dimensional requirements of the drawing and the various form and position tolerances are met, and oil is applied and stored in the warehouse.

2. The piston rod of the four column hydraulic press is made of 45 steel - rough turning - quenching and tempering treatment - precision turning of various parts to the appropriate size - surface quenching - grinding of the outer circle - surface electroplating of hard chromium - precision grinding of the outer surface to the specified size on the drawing - electroplating of hard chromium - oil coating and storage.

3. The piston and front seal of the four column hydraulic press are made of 45 # steel material, which is used for cutting, rough turning, and precision turning of chrome parts to meet the size requirements on the drawing, and then coated with oil and stored in the warehouse.

4. The four column hydraulic seal adopts high-quality Y-type seal ring, anti-aging, sealing, guide wear ring, oil resistant O-ring, PU material dust ring.

5. After the processing of each component is completed, it is necessary to clean all kinds of burrs, oil stains, remove iron filings, assemble according to the drawing processing requirements in a dust-free workshop, conduct experiments without leakage, and paint and store after passing the inspection.

Four column hydraulic press | Four column press column

The four column hydraulic press column not only supports the upper beam and hydraulic cylinder, but also can withstand a certain tensile force during operation, and also serves as a guide for the movable crossbeam. The raw material for the hydraulic press column is mainly made of 45 grade steel, which is used for cutting, rough turning, lathe machining of the outer circle with a remaining amount of grinding, and lathe machining of the rest to the appropriate size. The guide surface of the sliding column is quenched to ensure sufficient strength and rigidity of the column. The outer circle is finely ground, and the surface is electroplated with hard chromium to ensure that rust will never occur. The oil seal film is applied and stored. Both ends of the column are machined with metric threads - each end is made of 45 steel and locked with nuts and hydraulic press upper and lower beams respectively. Wear resistant gray cast iron guide bushings made of HT200 are installed at the four column through holes of the middle crossbeam, which are equipped with PD dust rings and polytetrafluoroethylene wear-resistant materials to prevent column strain and have good resistance to eccentric load.

fuel tank

The oil tank is one of the indispensable system components in the three beam four column hydraulic press system, mainly used to store sufficient oil required by the system, and has the function of dissipating heat and separating bubbles in the oil. The main performance characteristics of the fuel tank are as follows: 1. The shape of the fuel tank can be determined according to the overall layout, taking into account the tank capacity and the principle of achieving thermal balance based on the heating and cooling of the hydraulic system. Generally, a rectangular shape is used. The three directions of the box should be reasonably determined based on the size of the motor and other components installed at the top, as well as the height of the highest oil level.

2. The box body is welded with angle steel to form a skeleton, and then directly welded with 3mm thick steel plate. The strength and rigidity of the box can withstand the weight of the components installed on the top and the impact during operation. The bottom of the fuel tank has four feet, and there are lifting ears on both sides for easy heat dissipation, oil discharge, and transportation. One side of the fuel tank is equipped with an oil port and a cleaning window for the oil level display, making it easy to clean.

3. After welding, the inner wall of the fuel tank is polished to remove welding slag, burrs, and rust generated after welding. The slag on the inner wall of the fuel tank is thoroughly removed to achieve a smooth and flat surface, and finally polished.

4. The oil tank undergoes acid washing process to remove oil stains and debris from the inner wall of the tank and enhance the adhesion of the paint.

Four column hydraulic press | Four column press oil pipe

The hydraulic press adopts high-quality hydraulic oil pipes, and the oil pipes of the hydraulic system are generally made of high-pressure rubber steel wire braided hoses with multiple layers of steel wires inside, which can withstand high pressure up to 30MPA-35MAP or above. Some special parts are welded with cold drawn seamless steel pipes and then polished, pickled, neutralized, phosphated, cleaned, dried, and painted before installation.

Electrical Control

The hydraulic press electrical control drag motor has a small capacity, and the main circuit is started directly. QS is the power switch, fuse FU1 provides short-circuit protection for the main circuit, and fuse FU2 provides circuit protection for the control circuit. The thermal relay FR serves as overload protection. After pressing the start button SB2, the coil KM is powered on, the motor starts, and the hydraulic press starts working.
