Problems solved by technology

However, the hydraulic press is heavy and consumes a lot of raw materials in the manufacturing process; there is a problem that the load characteristics and the drive do not match during operation, the energy loss is large, the efficiency is low, and there is a large energy waste
[0003] Recycling the energy during the falling process of the execution unit has a certain effect on energy saving, but there are two processes of storage and reuse in the energy recovery process, so the energy conversion link is increased, and the complexity of the conversion process reduces the energy utilization. efficiency, and also affects the controllability of the system

Embodiment approach 1

[0056] Implementation mode 1: if image 3 As shown, the top view shape of the hydraulic machine frame 1 is a "V" shape composed of the first arm and the second arm. In the "V" shape frame, the first hydraulic cylinder 2 is at the front end of the first arm, and the second hydraulic cylinder 3 is located at the front end of the second arm, and an operating space is formed between the first arm and the second arm. The distance between the cylinder body of the second hydraulic cylinder 3 and the cylinder body of the first hydraulic cylinder 2 is L, The left and right distance is W; and there are: the arm lengths of the first arm and the second arm are both L / sin2α; α is the angle between the first arm and the second arm, 0° In this structural form, the body frame is composed of two equal-length arms, which can meet the requirements of any relative position of the hydraulic cylinder, reduce the processing difficulty of the hydraulic machine frame, and improve the flexibility of the...

Embodiment approach 2

[0057] Implementation mode 2: if Figure 4 As shown, the top view shape of the hydraulic machine frame 1 is a rectangle, and the first hydraulic cylinder 2 and the second hydraulic cylinder 3 are arranged on the front side of the rectangular frame, and are located on the front side at a distance of W', one on the left and one on the right. . In this structural form, the two hydraulic cylinders are arranged side by side on the front side of the rectangular frame, so that the two hydraulic cylinders are within the range of manual operation, which meets the needs of improving the efficiency of the manual operation process and reduces the difficulty of manual operation.

Embodiment approach 3

[0058] Implementation mode 3: if Figure 5 As shown, the top view shape of the hydraulic machine frame 1 is elongated, and the first hydraulic cylinder 2 and the second hydraulic cylinder 3 are arranged one after the other at the front end and the rear end of the elongated frame. The first hydraulic cylinder 2 and the second hydraulic cylinder The front and back distance of the hydraulic cylinder 3 is L'. In this structural form, the two hydraulic cylinders are placed at the front and rear ends of the elongated frame to ensure that the auxiliary automatic loading and unloading devices of the two hydraulic cylinders do not affect each other. .

[0059] In this embodiment, the dual-execution unit hydraulic press is initialized according to the following steps:

[0060] Step 1: Start the liquid pump 8 and keep the liquid pump 8 in working condition;

[0061] Step 2: Adjust the state of the first valve group 10, the second right valve group 12a, the second valve group 12b and t...

Abstract

The invention discloses a double-execution-unit hydraulic machine. The double-execution-unit hydraulic machine is characterized in that a first hydraulic cylinder, a second hydraulic cylinder, a first working table and a second working table are arranged on the same hydraulic machine frame together; the first hydraulic cylinder and the second hydraulic cylinder are arranged in parallel; the first working table and the second working table are located under the first hydraulic cylinder and the second hydraulic cylinder correspondingly; a first hydraulic unit is composed of the first hydraulic cylinder and the first working table; a second hydraulic unit is composed of the second hydraulic cylinder and the second working table; and a shared oil tank arranged for the first hydraulic unit and the second hydraulic unit and a shared power source composed of a motor and a hydraulic pump are arranged in the hydraulic machine frame. The raw material consumption and the part use at the manufacturing stage of the hydraulic machine are effectively reduced, and the energy consumption at the running stage can be effectively lowered.

Description

technical field [0001] The invention relates to a hydraulic press, in particular to a hydraulic press with double execution units, which is used to reduce material consumption in the manufacturing process of the hydraulic press, reduce energy consumption in the operation process of the hydraulic press, and improve the utilization rate of raw materials and energy in the life cycle process of the hydraulic press. Background technique [0002] As an important part of the forming equipment, the hydraulic press has a stable transmission and simple control, and has a wide range of applications. However, the hydraulic press is heavy and consumes a lot of raw materials in the manufacturing process; there is a problem that the load characteristics and the drive do not match during operation, the energy loss is large, the efficiency is low, and there is a large energy waste. [0003] Recycling the energy during the falling process of the execution unit has a certain effect on energy s...
