    • PROBLEM TO BE SOLVED: To provide an air circulation system of a roaster, by which a uniform air flow cycle is formed inside the roaster.
      SOLUTION: The roaster 100 is equipped with: a first air flow space 10; a second air flow space 20 having an air inlet port 21; a fan bracket 33 that is installed in the second air flow space 20 and provided with an inlet port 31 and an outlet port 32; a fan 30 installed inside the fan bracket 33: a rotary motor 40 for driving the fan 30; a board 50 for placing a baking plate 70 thereon; an electric heater 60 fixed on a holding base 51 of the board 50; and the baking plate 70 in which an oil discharge port 71 is formed. In the roaster 100, air flowed in the second air flow space 20 through the air inlet port 21 by the rotation of the fan 30 is passed through the fan bracket 33 and made to flow in the inner space of the roaster 100. The air is then exhausted from the oil discharge port 71 of the baking plate 70 and again flowed in the second air flow space 20 through the air inlet port 21.

    • The invention relates to foundry engineering and is used for producing intricate-shaped articles, including automobile wheels or the parts thereof exhibiting improved physical properties and performance characteristics. The production of the intricate-shaped parts, in particular automobile wheels by hot volume forging is economically unsound, that is why, actually all over the world the mass production of products like automobile wheels is mainly carried out by casting. However, the quality of hot forged parts is much higher than that of mould parts in spite of modern high accuracy casting methods. For this reason, the improvement of the mechanical properties and performance characteristics of mould parts is an urgent task. In order to solve said problem, a liquid forging associated with forming methods is used. The aim of said invention is to improve the quality of the intricate-shaped products such as automobile wheels having considerable variety of the cross sections of the various parts thereof, in particular the middle and peripheral relatively thin-walled parts of articles, like vehicle wheels, or parts which are distant from the melt pouring point when said articles are produced by liquid forging and hot shaping. Said production methods make it possible to improve the quality level to the quality of hot-stamped products at least for the most critical parts. The aim of the invention is also to increase the product quality by supplementary processing techniques and to reduce production costs by simplifying working processes. The inventive method for producing by liquid forging and hot shaping consists in carrying out metal or alloy pressure-crystallisation and hot plastic shaping, at least one part of a hot-shaping process is combined with crystallisation. Said method is characterised in that for producing configuration articles having the variable cross section areas of the parts and/or the peripheral part thereof which is distant from the melt pouring point, a crystallisation pressure value is selected such that it is equal to P, a strain rate and temperature are selected equal to epsilon and T respectively, wherein P, epsilon and T are plastic deformation parameters for given metal or alloy in the superplasticity condition. The pressure is raised to the P value during time t starting from the advancement of a punch to a melt mirror prior to the crystallisation of the part of the article having the smallest cross section area and/or the most distant from the melt pouring place. The die temperature is selected according to two following conditions: thirst, to make the provision for the plastic deformation in the superplasticity condition, and second, to take into account a melt temperature ensuring the liquid state of a metal or alloy during t time period.
    • 本发明涉及铸造工程,并且用于生产复杂形状的制品,包括汽车车轮或其表现出改进的物理性能和性能特征的部件。 复杂形状的零件,特别是汽车车轮的生产通过热量锻造在经济上是不健全的,因此,实际上在世界各地,汽车车轮等产品的批量生产主要是通过铸造来实现的。 然而,尽管现代高精度铸造方法,热锻件的质量远远高于模具零件的质量。 因此,模具部件的机械性能和性能特性的提高是一项紧迫任务。 为了解决上述问题,使用与成形方法有关的液体锻造。 本发明的目的是提高诸如汽车车轮等复杂形状的产品的质量,其具有各种各样的各部分的横截面,特别是制品的中间和周边相对薄壁部分,如车轮 或当通过液体锻造和热成型制造所述制品时远离熔融浇注点的部件。 所述生产方法使得有可能至少对最关键部件提高热冲压产品的质量水平。 本发明的目的还是通过辅助处理技术提高产品质量,并通过简化工作流程来降低生产成本。 通过液体锻造和热成型制造的本发明方法包括进行金属或合金压力结晶和热塑性成型,热成型工艺的至少一部分与结晶相结合。 所述方法的特征在于,为了制造具有远离熔融浇注点的部分和/或其周边部分的可变截面面积的构造制品,选择结晶压力值使其等于P,a 应变速率和温度分别选择为ε和T,其中P,ε和T是在超塑性条件下给定金属或合金的塑性变形参数。 在从具有最小横截面面积和/或最远离熔融浇注位置的制品的部分结晶之前的时间t期间,将压力提高到从冲头前进到熔融反射镜的时间t。 模具温度根据以下两个条件选择:渴望在超塑性条件下提供塑性变形,其次,考虑到在t时期内确保金属或合金的液态的熔体温度。
