Embodiment 1

[0049] This embodiment is a method for determining the thinning amount of the inner and outer rotary wheels when the counter wheel is spinning the cylindrical part. The material of the cylindrical part is ultra-high strength steel 31Si2MnCrMoVE.

[0050] The diameter D of the cylindrical part is 2500 mm, the initial wall thickness of the spinning blank is 40 mm, and the counter-wheel spinning forming process of synchronous reverse spinning of four pairs of spinner wheels is adopted.

[0051] The concrete process of this embodiment is:

[0052] The first step is to determine the factors affecting the amount of thinning.

[0053] The thinning amount is the thinning amount when the cylindrical member is spun internally and externally.

[0054] The influencing factors of the determined amount of thinning include the diameter D of the thin-walled cylindrical part, the initial wall thickness t of the spinning blank 0 , Metal material type and strength, spinning machine rigidity, ...

[0086] In this embodiment, the existing technology is used to determine the thinning amount of the inner and outer rollers of the ultra-high-strength steel 31Si2MnCrMoVE cylindrical part by the counter-wheel spinning, and to process the counter-wheel spinning cylindrical part.

[0087] The diameter D of the ultra-high-strength steel 31Si2MnCrMoVE cylindrical part is 2500 mm, the initial wall thickness of the spinning blank is 40 mm, and the counter-wheel spinning forming process of synchronous reverse spinning of four pairs of spinner wheels is adopted.

[0088] The concrete process of this embodiment is:

[0089] The first step is to determine the total thinning of the pass.

[0090] In this embodiment, according to the traditional processing experience, the total thinning amount of the wheel spinning pass is 30%-35% of the initial thickness of the spinning blank. In this embodiment, 30% is taken, the wall thickness of the spinning blank is 40 mm, and the total thinning amou...

Abstract

The invention discloses a method for determining the thinning amount of inner and outer spinning rollers of cylindrical part pair roller spinning. By comprehensively considering the influence rule of factors such as the diameter D of the thin-walled cylindrical part, the initial wall thickness t0 of a spinning blank, the types and strength of metal materials, the rigidity of a spinning machine, the number of spinning rollers, the radius and attack angle of rounded corners of the spinning rollers, the cooling mode and the flow of cooling liquid on the spinning forming precision of the thin-walled cylindrical part, the total pass thinning amount delta t of the cylindrical part is determined; the thinning rate theta corresponding to the pass total thinning amount delta t is 30%-80%, and the calculation method for determining the inner spinning roller thinning amount delta t1 and the outer spinning roller thinning amount delta t2 during paired wheel spinning of the thin-walled cylindrical part according to the total thinning amount delta t provides a basis for calculation and selection of the inner spinning roller thinning amount delta t1 and the outer spinning roller thinning amount delta t2 during paired wheel spinning of the high-precision thin-walled cylindrical part. The invention is used for guiding the actual production and machining process of paired wheel spinning of the thin-walled cylindrical part, conveniently and rapidly setting the thinning parameters of the inner spinning wheel and the outer spinning wheel and stably forming the high-precision paired wheel spinning cylindrical part.

Description

technical field [0001] The invention relates to the spinning manufacturing industry, and specifically defines a calculation method for the thinning amount of inner and outer rotors when a cylindrical part is rotated against the wheels, and is used to guide the production and processing of the cylindrical part during the counter-wheel spinning. Background technique [0002] With the rapid development of my country's aviation, aerospace technology and national economy, the demand for thin-walled metal spinning cylindrical parts with a diameter of 2500mm and above is also increasing and more urgent, and the precision requirements of the parts are also increasing. High, the use of core-less wheel spinning process can effectively solve this problem, and has the advantages of flexible processing, simple equipment and high forming precision. At present, for cylinders with a diameter of 2500mm and above, the core-less counter-wheel spinning process is adopted. This process technology...
