 Benefits of custom cold forged bushing,cold heading metal sleeve bushing

 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.

Advantages of cold heading

SpeedDepending 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.
EconomyWhen 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.
StrengthThe impact process naturally work hardens non-heat treatable alloys, while the heat treatable alloys can be heat treated in normal fashion after processing.
ToughnessThe 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.
VersatilityAfter 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.
ConsolidationImpacts 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 “piston pins” ?

In the moving parts, since the long-term wear and tear caused by friction of parts, the shaft and the hole when the gap wear to a certain extent when parts must be replaced, so the designer in the design of a low selection hardness, wear better materials for the sleeve or bushing, thus reducing wear of the shaft and the seat, when the sleeve or bushing wear to a certain extent be replaced, this can save the shaft or housing due to the replacement cost, in general, the bush and the seat are made interference fit with the shaft clearance fit, because no matter how kind or unavoidable wear, can only prolong life, and shaft parts are relatively easy to process; there are also some new designers do not like the design, that this at the time of manufacture cost increases, but after a period of time after use, or maintenance according to this method is the transformation, but the transformation is likely to cause the accuracy of the device is reduced, the reason is very simple, secondary processing is not guaranteed seat location of the hole center .
Bush in some low speed, high radial loads and require a higher clearance places (such as camshafts) be used instead of rolling bearings (in fact, can be considered a sliding sleeve bearing), materials that require low hardness and wear resistance, the shaft housing bore by grinding scraping, can achieve high precision fit, on the inner wall of the tank must have a lubricant, bushings lubrication is very important, dry grinding, it will soon be scrapped shaft and sleeve, where the recommended installation when scraping inner sleeve hole wall, so you can leave many small pits, lubrication bushing and sleeve is the choice of different models depending on the mining conditions. The main conditions are: pressure, velocity, pressure-velocity product, lubrication, load properties. Rotation and axial sliding movement requirements are not the same, there is no lubricant performance varies widely, largely determine the speed and pressure sleeve life.
Bush is generally divided into two categories: First, in order to facilitate disassembly may be. The other is used as a sliding bearing. Prevent axial movement of the sleeve is generally avoid stress concentration area (such as thickness variation and the poor), anti-shaft fracture in the vertical axial flow pump, mixed flow pumps, deep well pump, rubber bushings and bearings or Thordon bearing components “Lubrication deputy,” but in some horizontal pumps, such as in the open double-suction pump, sleeve axial play a regulatory role, while packing sleeve is sealed role together with the filler. The main role is wearable, belonged mainly wear-protective role of fall protection.
1. The bushings are generally played the role of sliding bearings. In order to save material load sleeve design according to the thickness required for the axial bearing. Generally used copper alloy and bearing. Sleeve openings and do not open the points, which need to be based on the structure. General sleeve can withstand axial load, or can only afford a small axial load. Or add thrust bearings. Axis is generally round.
2. bushes lining the role of general play. The shaft may be of various shapes, the liner is also true. Bushing can be used to corrosion, such as the elimination of assembly space.

Bushing 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.
