Hydraulic Press: Principle, Technology and Application

图片
Principle of Hydraulic Press A hydraulic press is a machine press using a hydraulic cylinder to generate a compressive force. The hydraulic press operates by forcing hydraulic fluid into a double-acting piston. The compressive force generated within the smaller hydraulic cylinder pushes the fluid into a larger cylinder, where greater force and pressure are applied. As the larger piston moves, it forces the fluid back into the smaller piston cylinder. Technolgy of Hydraulic Press Hydraulic presses are a very cost-effective and highly productive option when manufacturing small and medium batches of stamped parts compared to other equipment, but the cost ratio is higher and it is an unnecessary and unjustified additional cost, because it is impossible to generate profits. The profitability of hydraulic presses is improved by the access to new energy efficiency technologies that can be used for hydraulic presses. In addition, the technical characteristics of hydraulic presses guarantee...

Deep Drawing Press Process

图片
Deep drawing press process is quite challenging task to simulate due to requirement of multiple stages & precious tool design.Deep drawing is a sheet forming operation, in which the sheet is placed over the dieopening and is pushed by punch into the opening.The sheet is held flat on the die surface by using a blank. deep drawing press process In the deep drawing process, the blank-holding force (BHF) is an important process parameter affecting the energy consumption and the successful production of parts. In the present work, both experiments and finite element simulations have been conducted to investigate the influence of constant and time variable BHF on drawing force(DF) and thickness distribution in the deep drawing process of cylindrical and square cups.A finite element model was developed in the AutoForm software and validated with experiments. The developed model has been used for the simulation of deep drawing process of AA6016-T4 aluminum alloy sheet. The experiment...

Which Hydraulic Press is Better: Frame and Four Column

图片
It is difficult to directly judge which one is better between the frame hydraulic press and the four column hydraulic press. They have their own advantages and disadvantages in different application scenarios and requirements. The following is a specific comparison: Structural features Frame hydraulic press: It adopts an integral steel plate welded frame frame with good overall rigidity and high compressive strength; most of the sliders are guided by 45° inclined rails with high guiding accuracy; the fuselage structure is usually composed of an upper crossbeam, a lower crossbeam and two columns, which can form a larger upper and lower activity space for easy pressing of the workpiece. Four column hydraulic press: It adopts a four-column three-plate structure with better rigidity and accuracy; it consists of a hydraulic cylinder, a crossbeam, a column and a filling device, and has a simple, economical and applicable structure. Which Hydraulic Press is Better: Frame and Four Column ...

What is Hot Forging Press?

图片
Hot forging press is a forging equipment that can complete various free forging processes and is one of the most widely used equipment in the forging industry.Delishi/Goodsjack hot forging press adopts servo control system, stable beat control, high energy saving. Frame guide structure, fast forging 2~5 processes, 3~30s/time forging speed, high forging precision. hot forging press Process technolgy of hot forging Hot forging presses use an electric heating system to heat a metal part, called a billet or workpiece, to about 75% of its melting temperature. The metal is then shaped using processes like hammering, pressing, or upsetting. The heat and strain rate cause the metal to deform and recrystallize simultaneously, which prevents strain hardening. Average temperatures for hot forging includes Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F) Copper (Cu) Alloys - 700°C (1 292°F) - 800°C (1 472°F) Steel – up to 1 150°C (2 102°F) Factors to Consider During Hot Forging Proce...

Dust Protective Device of Hydraulic Press A hydraulic press with good dustproof effect comprises a fixed base frame, a support foot seat is fixedly connected to the bottom of the fixed base frame, a support rail column is fixedly connected to the top of the support rail column, a fixed sleeve is fixedly sleeved to the top of the support rail column, a support plate is fixedly sleeved to the surface of the fixed sleeve, a hydraulic cylinder is fixedly plugged to the middle of the support plate, and an electric push rod is plugged to the bottom of the hydraulic cylinder. The hydraulic press device with good dustproof effect can drive the threaded shaft to rotate inside the internal threaded tube by twisting the adjustment button, so that the threaded shaft pushes the slider to slide inside the slide groove, thereby push...

Hydraulic Press with Double-Station Quick Die Change

图片
Hydraulic Press with Double-Station Quick Die Change refers to a hydraulic press equipped with a system that allows for rapid switching between two different sets of dies (or molds) simultaneously, typically achieved through a dedicated die cart with two separate stations where one die set is pre-positioned while the other is actively being used on the press, significantly reducing downtime during die changeovers. hydraulic press with double station quick die change Following are brief introduce of hydraulic press with double-station quick die change. Structural design Dual-station bench: It has two stations, which can be operated simultaneously or alternately to improve production efficiency. For example, in the production of automotive parts, one station is for stamping and forming, and the other station can simultaneously change or prepare molds. Mobile workbench: It is usually equipped with high-precision linear guides and drive devices to achieve fast and smooth movement ...
