摘要： The present invention discloses a modified process of die manufacturing which substantially improves the wear life of the dies. The process consists of introduction of shot blasting operation after the machining operation and before the nitrocarburising operation. The process increases the case depth of the surface hardened layer thereby increasing the wear life of the hot forging dies. Gaseous Ferritic Nitrocarburising (GFN) process is carried out on die steel material for increasing the surface hardness. Performance of the surface hardening process depends on surface preparation and its treatment. Surface preparation entails modifying roughness and residual stresses on the surface. The shot blasting step of the invented process introduces uniform roughness and compressive residual stresses on the surface, which helps to increase the hardening depth during GFN.
摘要翻译：本发明公开了一种模具制造的改进方法，其大大改善了模具的磨损寿命。该过程包括在加工操作之后和氮碳共渗操作之前引入喷丸操作。该过程增加了表面硬化层的壳体深度，从而增加了热锻模的磨损寿命。在模具钢材料上进行气态铁素体氮碳共渗（GFN）工艺，以提高表面硬度。表面硬化过程的性能取决于表面处理及其处理。表面处理需要改变表面的粗糙度和残余应力。本发明方法的喷砂步骤在表面上引入均匀的粗糙度和压缩残余应力，有助于增加GFN期间的硬化深度。

摘要： The present invention describes a process to make enhanced fatigue strength micro-alloy steel. In the process of the present invention, the soaking temperature is maintained in the range of 900 °C to 1050 °C and soaking time in the range of 30-60 minutes depending on size of crankshaft to get refined grain size. Distortion of the components is prevented from occurring with provision of adequate supports especially designed for the process. Forged parts made using the process, such as crankshafts, have a refined grain pattern and result into 20 to 25% enhancement in torsion fatigue strength & 10-25% enhancement in bending fatigue strength. The present invention thus provides an enhanced ratio of the strength to material density and a micro-alloy whose torsion fatigue strength and bending fatigue strength are greater than the currently available micro-alloy steels.

摘要： The invention discloses a method of producing a Crown Wheel involving production of a ring by ring rolling process and further production of near net shape tooth profile by sequential stepwise forging. Conventional methods have several disadvantages e.g. excessive machining time, expensive gear cutting equipment, short life of cutting tools, possible strain hardening and residual stresses in the cold-forged parts and subsequent distortion during heat treatment and a high level of rejection of parts, among others. The invention discloses a method of manufacturing near-net shape crown wheel comprising the steps of making an annular ring using hammer forging, punching, piercing and ring rolling followed by blocker and finisher forging for manufacturing of gear teeth on the ring. Blocker forging is followed by trimming and piercing operation for flash removal. Hot forging operation (hammer blocker forging and finisher forging) is followed by cold coining process for improving the precision of the as-forged teeth profile.

摘要： The weight of the crankshaft is among the many factors that adversely influence the engine performance. Reducing the weight of the crankshaft without affecting its strength and balancing characteristics would improve the engine performance. The present invention provides a crankshaft and the process of manufacturing it such that its weight is reduced at least by 5-10% in contrast to conventionally manufactured crankshafts of comparable specification. This is achieved by reducing machining allowance which is provided during forging design, such that it does not adversely impact its strength and balancing ability. Moreover the additional aspect of kidney pocket inclusion into the combined area of web and counterweight profile reduces weight of crankshaft further at least 5%. A reduction in total machined area of the webs is also another aspect of the present invention.

摘要： A forging process to manufacture Aluminium wheel discs for heavy vehicles using small tonnage hammer is disclosed. It uses step-wise forging operation to achieve final shape of the alloy wheel. A minimal amount of machining is required. The process starts with a preform made from a round extruded billet and follows through with a pancaking and buster operations further followed by blocker and finisher operations. It is noted that grain flow lines in the product are continuous because the initial flow lines are present in extruded billet and it has greater material strength than the products manufactured with conventional processes that involve joints and welding.
