Design principleapplication of oil block

发布时间:2016-01-04    点击次数:

The oil block is a collection of dispersed hydraulic circuits. A block of oil is simply a block that controls the work of hydraulic oil. Usually made of metal. For each hydraulic system, the hydraulic block shall be designed separately according to the hydraulic principle diagram. The utility model has the advantages of simplifying the installation, the overhaul, the replacement and the maintenance of the hydraulic system. The disadvantage is that the design and processing requirements are higher, and the cost of single parts is high. Not suitable for single piece small batch production.
A block of oil is simply a block that controls the work of hydraulic oil.
In the hydraulic system, the configuration of hydraulic components is usually integrated configuration, in which the integrated block configuration is to install plate hydraulic valve on the surface of the oil block. It has the characteristics of compact structure and convenient maintenance. For a hydraulic system consisting of multiple basic loops, the hydraulic basic circuit is usually grouped according to the composition of the equipment unit, each of which corresponds to an oil circuit block. A slight omission in the design of the oil block will result in errors in design and manufacture. Therefore, it is very important to choose a professional design software to design oil block.
For oil computer aided testing system for hydraulic pump to the electromagnetic relief valve and cartridge type one-way valve installed in the computer aided testing system for hydraulic pump oil to of electromagnetic valve and cartridge type one-way valve installed
General design steps of oil block:
Separate the valve and the oil circuit according to the schematic diagram; confirm the component list and divide the required component list.
The standard database searches for the standard parts and also designs and saves the nonstandard parts that are used.
Draw the oil block stereo diagram and determine the position of each valve installation bottom board.
(1) establish the shape of oil block.
(2) temporary oil block size (X, Y, Z).
(3) placing components. Find the required components, mounting surfaces, bottom plates and hole models. In this process, you can use the command language to rotate and move the mounting surface to the proper position.
Connect the holes that need to be connected together. Do not calculate the hole depth and coordinate when the oil passage is connected. In the connection of the oil circuit, the designer is on the two-dimensional expansion chart design, and through the three-dimensional perspective of the oil connections clearly see the situation, and modify it. Therefore, to ensure the accuracy of the design, but also to improve the design speed.
After the oil hole is connected, wall thickness inspection is also required. If you do not meet the standard, you need to adjust the oil circuit.
The location of each hole can be marked by using the coordinate value on the drilling list. If the oil block is processed by a numerical control machine tool, the G code can be easily edited by using a list of drilling tables, and no other CAM software is needed.
The 2D engineering drawings can be generated directly by using 3D design software.

After checking the drawings correctly, they can be processed by the factory.
