Problems solved by technology

However, in working practice, the working pressure of the accumulator in the above two inventions is determined by the working pressure of the hydraulic pump. The hydraulic pump stores energy for the accumulator under high pressure for a long time, and the working fatigue of the hydraulic pump is high and the failure rate is high.

Embodiment Construction

[0019] The present invention will be further explained below in conjunction with accompanying drawing:

[0020] as attached figure 1 As shown, the pressurized energy storage device includes: energy storage tanks 6 and 6', air pressure tanks 7 and 7', and a partition device is provided between the energy storage tanks 6 and 6' to divide the tank into chamber A and chamber B, chamber A Pistons are set in chambers B and Cavities respectively, and a piston rod is arranged between the pistons. The piston rod passes through the separator and rigidly connects the two pistons so that the two pistons move synchronously in the chambers; the rodless chamber of A chamber is an air chamber with a rod The chamber is the oil chamber, the rodless chamber of chamber B is the oil chamber, and the chamber with the rod is the air chamber; two sets of pressurized energy storage devices are set up, and the energy storage tanks 6 and 6', and the air pressure tanks 7 and 7' are divided into two group...

Abstract

The invention relates to an efficient transmission type free forging hydraulic machine. The machine comprises a hydraulic cylinder, a main hydraulic pump and pressure increasing and energy storing devices. According to the machine, two pressure increasing and energy storing devices are arranged between the hydraulic pump and the hydraulic cylinder of the free forging hydraulic machine, and the twopressure increasing and energy storing devices are capable of alternatively supplying constant-pressure or pressure-increased pressure oil to the hydraulic cylinder of the forging hydraulic machine,so that the hydraulic pump can work in a low pressure state; the hydraulic cylinder in the free forging hydraulic machine realizes the beneficial effect of obtaining hydraulic oil with two pressure types; and the purposes of storing the complementary energy of the hydraulic machine, and efficiently transmitting are achieved. The machine has the advantages of being reasonable in resource distribution, simple in arrangement structure, good in pressure increasing effect, and obvious in energy conservation and consumption decreasing.

Description

technical field [0001] The invention relates to a free forging hydraulic press, in particular to a free forging hydraulic press which adopts a hydraulic pump-a booster energy storage device as a power source to realize high-efficiency transmission, and belongs to the technical field of hydraulic transmission. Background technique [0002] The specifications of the free forging hydraulic press are usually relatively large, and the weight of the forgings produced is also very large. Therefore, it is necessary to set up multiple high-power hydraulic pumps as the power source of the hydraulic system. Provide power. In actual working conditions, there are a large number of hydraulic pumps in the hydraulic system of the traditional free forging hydraulic press, which repeatedly run dry for a long time. Although the power configuration meets the requirements of the forging line speed, the power resources and energy are seriously wasted. In order to solve the above problems, in the...
