New Double-beam Hydraulic Press: Structural Design and Topology Optimization

-
Traditional large-scale three-beam hydraulic presses have good stability, but due to the large mass of the three-beam structure slider, it is not easy to deform elastically. When pressing the workpiece, the slider and the workbench are prone to inconsistent pressure deflection, resulting in uneven thickness distribution of the parts. In addition, in order to adapt to various mold heights, the three-beam hydraulic press structure frame is usually designed to be higher, which not only increases consumables but also makes the slider travel too long, making it difficult to control the pressing accuracy.
New Double-beam Hydraulic Press
Based on this, we proposed a new double-beam hydraulic press structure. The specific work is as follows:
1. In order to solve the problem of uneven thickness of parts, the traditional slider pressing method is changed to the upper and lower mold clamping method of the workbench. The workbench is installed on the upper and lower beams respectively. During pressing, the upper stroke large main cylinder is used to pressurize the middle of the thin plate steel workbench according to the deflection line of the part under pressure, and the four corners are leveled to ensure that the parts have the same degree of deflection and bending when pressing. The problem of uneven thickness of parts caused by the inconsistency between the slider and the workbench deflection line is effectively avoided, thereby optimizing the large-mass slider.
2. In order to solve the problem of excessive travel of the three-beam slider due to different mold heights, an openable locking mechanism is introduced, so that the upper beam structure can be adjusted along the column, so that the hydraulic press can be adaptively adjusted according to different mold heights, avoiding unnecessary long travel during pressing.
The development of a new double-beam hydraulic press involves several critical steps, including structural design and topology optimization.

Hydraulic Press Machine Speed Slow How To Solve

-

  If your  hydraulic press machine  speed gets slowly,following are methods to solve it. 1. Air in the hydraulic cylinder When the hydraulic press machine pressing speed gets slowly, we should first consider that air in the hydraulic cylinder, interrupt the corresponding exhaust operation through the exhaust equipment of the machine, and check whether there is air in the movement direction of the piston rod. If so, it may be If the sealing ring is defective, the sealing ring should be changed in time. 2.  Check whether the hydraulic pump is operating normally When the hydraulic press machine moves slowly and the hydraulic pump runs irregularly, and sometimes it may be blocked or slightly seized, it means that there is a problem with the hydraulic pump and the hydraulic pump should be repaired or changed in time. 3. Check the operation of the piston When the hydraulic cylinder of a hydraulic press machine with a buffer device is intermittently started in reverse, the ...

The speed regulating circuit of the hydraulic system of the hydraulic press is the core circuit. The hydraulic circuit selection for hydraulic press, must start with the selection of the speed regulating circuit (including determining the circulation method of the oil passage and the oil source structure method). Hydraulic Circuit Selection for Hydraulic Presses □ Speed regulating circuit Select the speed regulating circuit according to the pressure, flow and power of the hydraulic actuator working condition diagram and the system's requirements for temperature, working stability, etc. □ Rapid motion circuit and speed switching circuit The rapid motion loop is closely related to the speed regulating loop. When selecting the oil source mode, system efficiency, temperature and other issues in the speed regulating loop, the rapid motion loop must be considered. Once the speed control loop is confirmed, most of the rapid motion loop is also det...

The  hot forging hydraulic press for piston rod  adopts a three-beam and four-column structure, which is mainly composed of a fuselage, an oil cylinder, a hydraulic transmission system, an electric control system, and a lubrication system. This machine has an independent power system and electrical system. The hydraulic system adopts advanced two-way cartridge valve control technology, which effectively solves hydraulic control problems such as large flow, fast speed and fast pressure relief of forging hydraulic presses.                                          Maintenance of  Hot Forging Hydraulic Press for Piston Rod 1. Daily inspection, maintenance and replacement of vulnerable parts. 2. Lubrication and anti-wear of movable metal parts, and fastening of standard parts (such as bolts and nuts). 3. Maintenance of the surface and interior of the hot forging piston rod ...
