What are hydraulic fittings used for?


Hydraulic fittings ;connect conductors such as hoses, pipes, and tubes in a hydraulic system. Most fittings have a male and female component that joins to form a connection. These connections help contain and direct the flow of hydraulic fluid in the conductor while preventing leaks and maintaining pressure. Different fittings allow designers to change flow direction, the elevation of lines, or split flow. Crimping is the most common method for assembling hoses and fittings. Once the crimp specifications have been checked for the specific hose and fitting, a crimping machine is adjusted to the appropriate crimping diameter setting. The next step is to lubricate the fitting, put it on the end of the hose, and then put it in the crimping machine.


Some companies, Parker, for example, offer a no-skive option on their hoses. Skiving refers to a process where part of the hose cover or even the inner tube is removed before a hose end is attached. No-skive hoses do not require this step. Many prefer no-skive options because it makes hose assembly quicker and reduces the risk of hose damage during crimping.


Fitting geometries include crosses, plugs, elbows, and others. It’s important to pay attention when identifying the threads of the connections. Often, connections from one standard appear to thread into another standard port but do not have enough engagement to be safe. Furthermore, most fittings are brand-specific for certain hoses and may not work with other brands. While fitting dimensions often correspond to the size of the conductor there can still be a variance in fitting options for one size of pipe or tube.


Fittings are made of many different materials including stainless steel, brass, plastic, Monel, and more. Not always, but often fittings match the material of the conductor used in a system. This multitude of materials creates fittings with a wide array of performance capabilities. Most hydraulic fittings have designated pressure and temperature ratings as well as size and dimension standards set by the SAE.






Hydraulic Fitting Blank


Hydraulic fittings form part of a hydraulic system that connects hoses, pipes, and tubes. There are various fittings that are used to connect the system together and help the hydraulic fluid to flow through. Hydraulic fittings, or hose fittings, are used to connect hydraulic hoses and pipes to other components such as valves and pumps.


Hydraulic Fitting Blank ;will usually have a male and/or female connection which joins to other components. The connections are usually threaded and there are several thread standards available, such as JIC, BSP, and BSPP. BSP male threads will seal with BSP female threads, for example. Popular materials include plastic, brass, and stainless steel fittings.






Compression fittings provide water-tight connections by using pressure to seal the connection. They usually use a compression nut which, when tightened, removes space between the ferrule and the pipe.


Threaded fittings have screw threads on both sides of the connection. They accept connections with compatible threads and screw together for a secure connection. Not all threads provide a tight seal and may benefit from additional coatings or seals.


Crimped fittings require the crimping of the hose to the fitting. You may require a crimping tool to achieve this.


Thread Types


Hydraulics machines are used all across the world and there are many components used in each system. Thread types are used to help make parts easily identifiable and easy to maintain and replace. Some examples of thread standards include:






Forged Blanks & Usages


Forging allows the required shape to be achieved with the minimum amount of waste material thus reducing the final costs.


Where necessary bars can be enlarged at one or both ends to be machined afterward, once again reducing machining time and cost of raw material.






The Benefits of Right Angle Forging Blank:


Machining & Fastener Companies:


? Save up to 50% on material.


? Improved machining cycle times.


? Increase shop capacity as a result of reduced cycle times.


? Better metal grain flow and strength.


? Reduced material waste.


? Reduced energy cost.


? Reduced tool and tip cost, because of less material removal.






Principles for the Selection of Forging Blanks


Forging rough ingress processing is the process of forging production, the quality of round body forging blank, and productivity will have an important impact on the quality of forgings, performance, life, and economic benefits of enterprises. Forging a rough processing process, equipment accuracy and performance determine the quality of the blank. The quality of forging blanks directly affects the precision of turning to process, and the quality of turning to process affects the precision and efficiency of grinding. Therefore, the choice of forging blanks in the whole forging process plays a very important role, forging rough selection principle, should meet the requirements of use under the premise, as far as possible to reduce production costs, so that products in the market competitiveness.






Next is the selection principle of forging blank operations, with the following:


Principle of Forging Process


The use requirements of forgings determine the characteristics of the shape of the blanks, different use requirements, and shape characteristics, forming the corresponding rough forming process requirements. The requirements for the use of forgings are reflected in the external quality of its shape, size, processing accuracy, surface roughness, and internal quality such as its chemical composition, metal tissue, mechanical properties, physical properties, and chemical properties. For the use requirements of different forgings, consider the process characteristics of the forging material (e.g. forging performance, welding performance, etc.) to determine which rough forming method is used. While selecting the rough forming method, we should also take into account the metal forging processability of subsequent machining.






Adaptability Principles of Forging


Some of the roughs, which are complex in structure and difficult to form by a single forming method, should consider not only the possibility of combining various forming schemes but also whether these combinations will affect the processing ability of machining.






Working Principles of Forging


The working conditions of the forge parts are different and the type of blank selected is different. The forming scheme of forging blanks should be selected according to the production conditions on-site. On-site production conditions mainly include the actual process level of on-site rough manufacturing, equipment condition, and the possibility and economy of foreign association, but also consider the use of more advanced rough manufacturing methods due to product development. To this end, the choice of blanks should analyze the existing production conditions of the enterprise, such as equipment capacity and staff technical level, as far as possible to use the existing production conditions to complete the rough manufacturing tasks.

What is a blank in forging?


Blank — Raw material or forging stock (also called a "slug" or "multiple") from which a forging is made.


Application of aluminum forged parts


High-strength aluminum alloys have the tensile strength of medium-strong steel alloys while providing significant weight advantages. Therefore, aluminum forged parts are mainly used in aerospace, automotive industry, and many other fields of engineering, especially in those fields, where the highest safety standards against failure by abuse, shock, or vibratory stresses are needed. Such parts are for example pistons,[citation needed] chassis parts, steering components, and brake parts. Commonly used alloys are AlSi1MgMn (EN AW-6082) and AlZnMgCu1,5 (EN AW-7075). About 80% of all aluminum forged parts are made of AlSi1MgMn. The high-strength alloy AlZnMgCu1,5 is mainly used for aerospace applications.
