Embodiment Construction

[0031] Such as figure 1 As shown, it is a production method of a bellows with high precision, high stability and long life in the present invention, which is mainly aimed at the production process of the bellows, and specifically includes the following steps:

[0032] (a) Tube billet reducing and thinning forming process: the load-carrying capacity of the elastic sensitive element is related to many material parameters of the elastic sensitive element, such as the material used for the elastic sensitive element, corrugation type, corrugation thickness, corrugation layer number, connection The temperature range of the material is -30℃~+120℃. Due to the limitation of the actual installation process, it is not fundamental to change the force. We should start from the safety performance and optimize the constituent materials of the elastic sensitive element itself to improve the strength, fatigue resistance and good rigidity of the elastic sensitive element itself. , toughness an...

Abstract

The invention discloses a production method of a corrugated tube with high precision, high stability and long service life. The method comprises the following steps: (a) conducting reducing and thinning processing on a tube blank; (b) forming a corrugated tube; (c) shearing an port of the corrugated tube; (d) punching at the corrugated tube blank top (e) conducting spray cooling and drying on the corrugated tube; (f) shaping the corrugation of the corrugated tube; (g) conducting thermal stability; (h) cleaning and drying the corrugated tube; (i) detecting the corrugated tube; and (j) packing and storing the corrugated tube. The method can fully exert the superplastic properties of the material, conduct limit deformation processing by the maximum degree; the formed corrugations are uniform, have good surface performance, and no wear; the corrugation forming clamping is convenient and reliable, has high degree of mechanization; the shaped corrugations have good shape size consistency, small stress concentration; heat stable treatment can eliminate processing hardening, recover plasticity and achieve excellent mechanical properties; and the corrugated tube after detection has the characteristics of high precision, high stability and long service life.

Description

technical field [0001] The invention belongs to the technical field of corrugated elastic sensitive element production, and in particular relates to a production method of a corrugated tube with high precision, high stability and long service life. Background technique [0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the direction of folding and stretching. The bellows has a thin wall and high sensitivity. The measuring range is tens of Pa to tens of MPa. Its open end is fixed, and the sealing end is in a free state. The auxiliary coil spring or reed is used to increase the elasticity. Under the action of internal pressure, it is elongated along the length of the pipe, so that the movable end produces a displacement in a certain relationship with the pressure, and the movable end drives the pointer to directly indicate the pressure. [0003] As the key core elastic sensitive components, compensating components and ...
