Embodiment Construction

[0040] In the prior art, when the members with inner circumferential ribs are formed by external rotation, there are disadvantages that it is difficult to control the amount of diameter expansion, and the technical indicators such as shape and size are difficult to meet. In addition, in order to be able to remove the parts from the mold, the external rotation forming mold It is necessary to adopt a resolution mold, which brings problems such as high mold cost and low use efficiency. In order to solve the above-mentioned defects, an embodiment of the present invention provides a spinning tool and forming method for a cylindrical body with inner circumferential ribs.

[0041] In order to solve the above defects, the main ideas of the embodiments of the present invention are:

[0042] In the embodiment of the present invention, the spinning tooling of the cylinder body with inner circumferential ribs is carried out on a machine tool, and the tooling includes external rotation too...

Abstract

The invention provides a spinning tool for a barrel with an inner circumferential rib and a forming method. Spinning is carried out on a lathe. The tool comprises an outer spinning tool and an inner spinning tool. The outer spinning tool comprises a core mold, an outer spinning rotary wheel and a centre; the inner spinning tool comprises a transferring disc, a balancing rotary wheel, a core mold,an inner spinning rotary wheel, a rotary wheel rod and a rotary wheel substrate. The aluminum alloy barrel with the inner circumferential rib is formed with high precision effectively by controlling the factors such as the assembly precision of the tool, the dimensional precision of a spinning blank and the spinning process parameters. The forming method provided by the invention is high in practicality. By adopting the process method and the tool, the spinning process is stable and reliable, the part is good in forming precision, and a feasible forming method is provided for forming barrel parts with inner circumferential ribs.

Description

technical field [0001] The invention belongs to the technical field of spinning forming, and in particular relates to a spinning tool and a forming method for a cylindrical body with inner circumferential ribs. Background technique [0002] The structure with inner circumferential ribs is the preferred design form to improve the rigidity, strength, and reduce weight of parts. The outer surface of this structure is generally cylindrical, conical, and curved generatrix. The processing of this kind of parts has the characteristics of complex structure, high processing difficulty, low material utilization rate and low pass rate. The forging machining method has high processing efficiency, but the material utilization rate is low. The casting machining method, although the material utilization rate is improved, but due to the influence of various casting defects such as casting sand holes and looseness, the qualified rate of parts is low. Moreover, the casting material has low m...
