EFD Induction crankshaft hardening systems are a proven way to meet stringent specifications, while at the same time minimizing costs. Induction hardening is a type of heat treatment in which metal parts are heated by electromagnetic induction and then quenched. The shaft type hardening machine adopts a modular layout structure, which can efficiently complete the induction hardening task of various types of parts. This is vital input for improving the usability. When induction heating machines are not needed, they automatically switch to an economical standby mode. CrankPro® Induction Heating Systems utilize patented SHarP-C™ (Stationary Hardening Process for Crankshafts) hardening technology, which eliminates work piece rotation during the induction heat treating process. A common use for induction hardening is for hardening the bearing surfaces, or “journals”, on automotive crankshafts or the rods of hydraulic cylinders. and production volume. FOCO induction specializes in the production of induction hardening machine. An automatic loading/unloading version is available. History Behind the Induction Hardening: The Michael Faraday is the person behind the induction hardening. As time went on, crankshaft designs became more complicated and heat-treatment speciﬁ cations became more challenging. HC Crankshaft Hardening installation The HC installations are specially designed for crankshaft induction heating and allow big series heat-treatment and integration in automatic manufacture line. The hardening process can be set individually for each bearing location and is also performed automatically. Whether with series products or package concepts aligned to the customer’s process, we stand by our customers with all of our experience and expertise and this for decades. For hardening crankshafts with lengths up to 1500mm, the SMS Elotherm system opens up a solution, for trucks and other large vehicles as well as many stationary units. A hardening process for a crankshaft which includes subjecting the crankshaft to a first induction hardening process to produce a hardened layer of a substantial thickness at all bearing locations and at all transitional points between the crank pins, journal pins and crank webs. Wear resistance behavior of induction hardened parts depends on hardening depth and the magnitude and distribution of residual compressive stress in the surface layer. The HardLine CIHM-R is a range of EFD Induction robot-type systems for fast, reliable and cost-effective hardening and tempering of crankshafts. Induction hardening is done by generating rapid heat in the crank by using a high frequency alternating magnetic field that provides the surface penetration required to strengthen the crank. CrankPro® Induction Heating Systems for crankshafts utilize patented SHarP-C™ (Stationary Hardening Process for Camshafts) hardening technology, which eliminates work piece rotation during the induction heat treating process. In continuous industrial operation, the machine can achieve cycle times under 30 s for hardening of four-cylinder passenger vehicle crankshafts. You're right, the crankshaft in the induction machine is a V8 crank and all cranks afterwards are inline 4 cranks. Besides managing various departments, he specialises in Crankshaft, Camshaft, and Stress Relieving heat treating processes. Auf einer Produktionsfläche von über 114.000 m² fertigen wir mit modernsten Fertigungseinrichtungen und exzellentem Technologiewissen Kurbelwellen bis zu 8 m Länge. Create an account. That means a profitable throughput of up to 120 crankshafts per hour, with consistently high quality within exactly specified tolerances. The invention relates to a method for induction hardening crankshafts comprising at least one crank pin and at least two main bearings, in particular to hardening said crank pin(s) using an inductor which operates in a contactless manner. Among other applications, it is used in passenger cars or trucks and as a large crankshaft for locomotives, ship propulsion systems or for large diesel engines for generators, compressors or pumps. Later the engineers at the Midvale steel and The Ohio Crankshaft Company use the Faraday’s electromagnetic induction and induction heating for the first time. Induction hardening depth at fillet of crankshaft (left) and microstructure in surface-hardened layer (right) Full size image After experimentally optimizing the induction hardening process parameters for the manufacturing of the specimens, the final heat treatment depth reveals an almost identical value of about 3 mm compared to the crankshaft. The high frequency prevents deep penetration of the energy into the workpiece and ensures that the shaft is hardened perfectly. These cookies may often be set by our advertising partners. Customers can choose exactly the required performance profile to avoid overcapacity and/or excess capital expenditure. The integration of hardening machines in our customers-production process is also done by us. • Combination of … Induction hardening uses induced heat and rapid cooling (quenching) to increase the hardness and durability of steel. Verical Induction Hardening Machine. All of our hardening machines have a modular structure, allowing them to be adapted, both overall and with regard to important details, to give users the greatest possible benefit.
