Bearing automatic finish forging single production line

Abstract

The invention relates to the technical field of bearing machining, in particular to a bearing automatic finish forging single production line. The bearing automatic finish forging single production line comprises a material moving mechanism, a machining mechanism and a discharging conveying belt. The material moving mechanism is arranged beside the machining mechanism. The discharging conveying belt is arranged between the material moving mechanism and the machining mechanism. The machining mechanism comprises a high-tonnage punching machine, an upsetting assembly, a punching assembly and a bottom cutting assembly. The upsetting assembly, the punching assembly and the bottom cutting assembly are arranged below the high-tonnage punching machine at equal distance. A stepping beam works to drive three mechanical arms to work synchronously, three blanks are driven to move on the high-tonnage punching machine, single machining of bearing steel rings is achieved, the production line is short, temperature is uniform, product quality is improved, forging temperature is uniform, and production efficiency and forging precision are improved; and due to double mold motion of the punching assembly, the punching assembly can cooperate with the mechanical arms conveniently to discharge the blanks, manual discharging is not needed, automatic work can be achieved on production of the bearing steel rings conveniently, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to an automatic precision forging single production line for bearings. Background technique [0002] The production of bearing steel rings requires upsetting, forming, and bottom-cutting processes, and the three processes use multi-function high-tonnage punching machines. Sleeves are used in the prior art (the material that falls after cutting the bottom of the steel is processed, processed into the inner ring of the bearing, and a single production line produces the inner and outer ring of the bearing). [0003] However, there are still the following disadvantages when using the existing technology in production. First, multiple equipments are needed when using the way of sleeve punching to produce, and the long production line will easily lead to uneven temperature, and the sleeve punching product is easy to produce burrs , The material of the inner ring is loose, whic...

Problems solved by technology

[0003] However, there are still the following disadvantages when using the existing technology in production. First, multiple equipments are needed when using the way of sleeve punching to produce, and the long production line will easily lead to uneven temperature, and the sleeve punching product is easy to produce burrs , The material of the inner ring is loose, which seriously affects the product quality

Second, in the prior art, in the punching forming step, only the upper die moves for punching forming, which requires the blank to be placed in the lower die groove for fixed forming. Such a production method requires manual processing after punching and forming. Unloading, unable to carry out automated production, reducing production speed

Third, in the prior art, water is used to lubricate and cool the head of the punching machine, and the friction force of the water is relatively large, which may easily cause the blank to be lifted when the punching machine is raised, thus affecting the processing process
