High-speed low-loss bearing ring discharging device

Abstract

The invention discloses a high-speed low-loss bearing ring discharging device. The high-speed low-loss bearing ring discharging device comprises a driving motor, a discharging assembly and a transmission mechanism, wherein the driving motor is used for providing power; three main shafts are arranged in the discharging assembly in a triangular positioning manner, discharging screws are arranged on the main shafts, the heights of threads on the discharging screws are gradually increased from one end of the discharging screws to the other end of the discharging screws, and the crest widths of the threads are gradually decreased; the transmission mechanism is used for connecting an output shaft of the driving motor and the three main shafts, so that the three main shafts synchronously rotate; and a discharging channel for allowing a pipe material to pass is formed among the three main shafts. According to the high-speed low-loss bearing ring discharging device, high-speed and low-loss discharging can be achieved, the discharging loss is less than 5%, the production cost is greatly reduced, the cutting speed is very high and is 2-3 pcs / s, the production efficiency is improved, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of bearing ring production, in particular to a high-speed and low-loss bearing ring blanking device. Background technique [0002] In the structure of bearings, there are generally outer rings and inner rings, which are collectively referred to as bearing rings. Bearing rings are generally cut by cold cutting steel pipes with blades. Cold cutting blanking, blade width is greater than 1.5mm, and material loss is greater than 15%, the bearing ring groove needs to be turned and formed, and the material loss increases by about 10%, resulting in a relatively large loss of material, exceeding 25%, and the cold cutting speed is slow, which can reach 2-3s / pcs, and the production efficiency is relatively high Low cost and high cost, so a new cutting method is needed to solve the above technical problems Contents of the invention [0003] The invention provides a high-speed and low-loss bearing ring blanking device, which ca...
