|Benefits of custom cold forged socket,cold heading metal housing socket|
Most of machined parts could be re-designed and re-manufactured to be parts made by technology of cold heading,which help you to get significant cost savings.
- Improve production effience and reduced Production costs:Because of using high speed manufacturing process. The speed reaches range from 10 pieces per minute for low volume large press work to to 450 pieces per minute on the cold heading process.
- Save material cost: Compared to a traditional machining process, cold forming process can save up to 70%.
- Better control product tolerance: compared to more expensive machining processes,less tolerance can be achieved throughout the production process by coldforming
- Higher and better quality surface: compared to conventional machined surfaces ,cold forming process can get result . The cold forming process can eliminate the need for costly secondary operations, such as welding, machining, etc, with careful product and process design,
- Improved part performance and characteristics: due to the metal deformation resulting in improved grain structure, while work hardening can yield significantly improved product performance,cold forming process can improve metal part performance and its characteristics.
See how the technology of cold forging/cold heading to save materials cost:
Advantages of cold heading
|Speed||Depending upon the size and complexity of the part and the nature of the equipment of producing them, production rates of 4000 pieces per hour can be achieved.|
|Economy||When compared to casting and machining labor the metal savings alone justify the conversion to an impact extrusion.In some cases when the aluminum slug is sized accurately, little or no trimming or other secondary operations are required.|
|Strength||The impact process naturally work hardens non-heat treatable alloys, while the heat treatable alloys can be heat treated in normal fashion after processing.|
|Toughness||The impact extruding process produces parts that are dense and porous-free in structure. This condition cannot be obtained in a casting process or by machining of a bar material.|
|Versatility||After impacting, the product can be treated the same as any other piece of material. Secondary operations such as machining, grinding, welding, bending, plating or anodizing can be performed in the same way as any other piece manufactured by a more conventional process.|
|Consolidation||Impacts can directly replace machined components, or welded or riveted assemblies, in many designs. The process often reduces product costs for secondary machining operations and in many cases increases the strength of a product that was previously an assembly.|
|General knowledge on “socket”|
Socket is composed by a number of hexagonal type within one or several of the sleeve and the sleeve of the handle structure, the inner sleeve of the hexagonal bolts in order of priority depending on the model, you can choose according to need.
Technical characteristics of the socket: 1, applicable to withstand tension and compression forces of various types of two-way reinforced concrete structures
Cold extrusion steel socket connection technology:
Construction steel structure connection. 2, materials, energy, and without restricting the types of steel components. 3, can be full connectivity. 4, can advance prefabricated, factory work, do not take the construction period, all-weather construction. 5, easy to operate, fast, construction speed, can greatly shorten the construction period
Technical features joint sleeve reinforced connection strength to industry standards JGJ107-96 in Class A joint performance requirements. Thread form, high precision, stable and reliable connection quality. A wide range of applications, suitable for diameter 16-40mm. Ⅱ, Ⅲ grade steel in any direction with the diameter and position of the connection. Adjustable: reverse threaded sleeve type suitable for iron steel cage Shui-peer connection can not be rotated at the rebar. Construction speed: threading in advance and on-site pre-processing, assembly and construction. Energy conservation, pollution-free, safe and reliable construction.
Socket wrench: it is more than a sleeve with hexagon holes or twelve angle holes and with a handle, extension rods and other annexes, especially for wrenching position is very narrow or very deep depression bolts or nuts
Production process: rough (there are a variety of specifications) – polish (remove burrs thorn etc.) – Turning (mainly molding) – polished surface – lithography (eg knurled, printed LOGO, etc.) – the heat treatment (for increase its hardness) – plating (nickel or chrome, etc.) – grab the black and other
Distinguish good and bad: look at the surface: Is there flash, specifications meet the size standard, without scratches, etc; see endoplasmic: measuring torque and hardness using special tools; measure the size; salt spray test etc.
First, in accordance with the classification using the drive:
1, pneumatic sleeve (also known as pneumatic sleeve)
2, manual sleeve
3, the electric sleeve: the electric socket wrench as a driving force.
Second, according to the material classification
1, chrome-molybdenum steel (Chrome-Molybdenum Steel), chromium (Cr), molybdenum (Mo) and iron (Fe), carbon (C) alloys, high temperature processing performance, processing and beautiful, the depth of hardening, the impact has absorbing performance, so often used in the industry of manufacturing pneumatic tools and large hand tools.
2, chrome vanadium steel (Chrome-Vanadium Steel), chrome vanadium steel is added chrome vanadium alloy tool steel alloying elements, mainly used in the manual tools.
3.45 # carbon steel, or 45 gauge steel, the carbon content of about 0.45%, due to good processing performance and multi-faceted treatment process to become commonly used in the processing of steel materials. Cr-Mo material in the above optimum material (chromium molybdenum steel) is the best material of the sleeve.
Socket quality detection and checking
Detected ways can be divided into labor detecting and machine automatic detecting. Labor is the most original and most widely used way of coincidence detection. In order to minimize the outflow of defective products, the general production of corporate officers by visual approach to packaging or shipment of product testing to rule out defective products (including bad teeth hurt, mixing, rust, etc.).
Another way for automatic testing machine, mainly magnetic particle inspection.
Magnetic particle testing is the use of the leakage magnetic field interacting with the magnetic particle defects of the bolt, bolt for possible defects (such as cracks, slag, mixing, etc.) differences in permeability and permeability of the steel, after magnetization of these materials are not continuous Kawasaki will occur at magnetic field changes, the magnetic flux leakage portion is formed at the surface of the leakage magnetic field generated in order to attract magnetic particles to form a magnetic powder defect accumulation – magnetic marks, under appropriate lighting conditions, showing the location and shape of the defect, for accumulation of these magnetic powder to be observed and interpreted, has reached the purpose of removing defective products.
