Example Embodiment

[0026] The technical solution of the present invention will be further described in detail below in conjunction with specific embodiments.

[0027] figure 1 It is an exploded schematic diagram of the flange at the automobile engine in the prior art, which is composed of the original flange 101, the original end cone and the original sensor nut 106. The original end cone is formed by splicing the end cone right part 102 and the end cone left part 103. The right part of the end cone 102 and the left part 103 of the end cone are fixed by welding. The right part of the end cone 102 and the left part 103 of the end cone are structurally symmetrical. The right part 102 of the end cone is provided with a right semicircular hole 104, and the left part of the end cone 103 is provided with a left semicircular hole 105 that matches with the right semicircular hole 104. The right semicircular hole 104 and the left semicircular hole 105 form a sensor mounting hole. The original sensor nut 106 ...

Abstract

The invention discloses an integrated cast flange, which comprises a ring flange, an end cone and a sensor nut, wherein the bottom end of the end cone is provided with a transitional part; the transitional part and the end cone are of an integrated structure; the end cone is fixedly arranged on the ring flange through the transitional part; the inner side surface of the transitional part is flush with that of the end cone; the outer side surface of the transitional part is circular-arc-shaped; further, the upper end and the lower end of the outer side surface of the transitional part are connected with the end cone and the ring flange in a smooth butting manner respectively; the end cone is provided with a sensor mounting hole; the sensor nut is fixedly arranged in the sensor hole; and the ring flange, the end cone and the sensor nut are formed by adopting integrated casting. The invention also discloses a manufacturing process of the integrated cast flange. The flange is high in strength and good in firmness; the service life of a product is prolonged; the tightness during the connection with an engine is good; the product is stable, is high in precision, and is not liable to deform; air leakage risks are greatly decreased; the manufacturing process of the integrated cast flange is a few in working procedures and short in working hour; the cost is decreased; and resources are saved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an integrated casting flange and a manufacturing process thereof. Background technique [0002] A flange for gas distribution is provided on the automobile engine, and this flange is also used for installing sensors. In the prior art, the flange is mainly composed of a flange, an end cone and a sensor nut. In the production process, the flange needs to be produced first by forging, the end cone is produced by stamping, and the sensor nut is produced by lathing. , and then weld the flange, end cone and sensor nut as a whole, not only the manufacturing process is complicated, the working hours are long, the cost is high, and resources are wasted, but also the flange sealing surface after welding is easily deformed, and the flatness is above 0.5, resulting in When it is connected with the engine, the seal is not good, there is a risk of air leakage, and there is a potential safe...
