Dalan Hydraulics will share with you the skills of designing hydraulic systems. Dalan Hydraulics will share with you the skills of designing hydraulic systems. The tips are as follows:
1. Adopt the principle of "three-oriented"
1 Parts should be replaced with standard parts or standard parts or purchased parts.
2 When designing splines and threads, it should be easy to use standard tools and measuring tools for processing and testing. In particular, priority should be given to the existing tools and measuring tools.
3 large structural parts, steel castings design, try to use fasteners without tapping, such as the use of welded nut plate instead of screw holes.
4 Try to use existing mature parts or mature structures and processes to make the products serialized and universal.
6 Choose a uniform taper, consistent thickness and size of the same steel casting material.
2, improve the design from shape and structure
1 Minimize parts. Combine several parts into one part, for example, change the weldment to a stamped part to reduce the number of parts.
2 Design the part into a symmetrical structure.
3 Parts of similar shapes used in several products are designed to be universal parts.
4 Simplify the shape of each part, improve the shape of the part, reduce the shape of the bend, and sometimes change the part that is difficult to ensure the dimensional accuracy during the pressing to the welded part.
3. Improve the process plan
1 Avoid unnecessary cutting, especially the cutting of the clamping reference surface.
2 Under the premise of ensuring reliable and reasonable use of components, reduce the processing accuracy level requirements such as dimensional tolerance, surface roughness and shape tolerance.
3 reduce the bending shape and complexity of parts, reduce scrap rate and manufacturing costs.
When the length of the 4 steel is cut, the flame cutting is changed to the steel cutting and cutting; the flame cutting of the general material is changed to shearing with the shearing machine; the rectangular strip is changed from the four sides to the strip. Steel, just shear cuts in length.
4. Adopting process technology that saves resources and reduces pollution
1 cast steel parts are changed to welded parts.
2 Under the premise of ensuring the strength of the parts and optimizing the thickness of the plate, try to reduce the weight of the parts. The design of the structural weldment must be such that the rib is stressed and the weld is stressed. The use of thick plates in the construction of structural weldments is often not a requirement for strength, but a need for stiffness, i.e., small deformation of the slab during welding, or small deformation when the weldment is loaded. Some individual slabs can often be replaced by thinner plates with appropriate ribs, which not only reduces the total weight, but also increases the load carrying capacity.
3 Select reasonable parameters such as weld length and weld angle.
4 Processes with less or no cutting are used to increase the strength of the workpiece and reduce the manufacturing cost.
5 Replace some free forging forgings with welded parts as much as possible.
6 Uniform parts heat treatment technical requirements and process specifications, so that different parts can be simultaneously heat treated in the same furnace to improve the utilization of electric furnace and save power consumption.
7 Make full use of the residual heat of the forging, continue heating after forging, and directly perform heat treatment such as forging and normalizing.
8 According to the specific conditions of the parts, develop reasonable heat treatment technical requirements.
9 When designing the hydraulic system, the overall layout of the machine should be fully considered. The volume of the hydraulic oil tank should be sufficient to minimize the amount of hydraulic oil; the pipeline is simple and compact, and the length is as short as possible. In the same way, when designing the electrical system and the brake pipe system, the cable or brake pipe should be made reasonable and the length should be the shortest.
5. Product design is a complex process of comprehensive information processing. The final result is to draw lines, symbols and numbers into reasonable design drawings. Designers should consider the following aspects:
1 Simplify the shape of each part to make the machine structure simple;
2 Combine the functions of parts to reduce the type or quantity of parts;
3 Apply new structures, new processes, new materials, new principles to simplify product structure and improve product reliability;
4 Decompose the parts and study the simplest structure of assembly and assembly;
5 group similar parts;
6 pairs of similar products are serialized by product serial number sequence;
7 to achieve the generalization and standardization of product parts.
