Long bar online automatic discharging device and method used for bearing production

Abstract

The invention relates to a long bar online automatic discharging device and method used for bearing production. The device comprises a production platform, a discharging assembly and a material conveying mechanism, wherein the discharging assembly and the material conveying mechanism are arranged on the production platform. The device further comprises a shearing device and a detection, sorting and temperature control system. The shearing device is a shearing punching machine, and the shearing punching machine is used for shearing a long bar into a to-be-forged piece and is provided with a feeding position and a discharging position. Through the arrangement of the shearing device, the detection, sorting and temperature control system and other structures, a long bar online punching machine medium-temperature discharging and segmented heating technology is developed, and discharging fracture flatness and the material weight error meet the technological requirements; and on material temperature control, a three-way automatic sorting technique of heating process online temperature measurement, dynamic automatic temperature control and discharge material temperature is adopted, so that the material temperature fluctuation is within a controllable range, an overburnt or under-temperature workpiece is prevented from flowing into a station, and therefore the operation safety and the forged piece quality are ensured.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to an online automatic blanking device and method for long bar material used in bearing production. Background technique [0002] Tapered roller bearings: can bear radial and axial loads at the same time, and double-row tapered roller bearings can bear bidirectional axial loads. Due to the sliding friction between the large end of the tapered roller and the rib of the inner ring, its limiting speed is often lower than that of a cylindrical roller bearing of the same size. Hollow tapered roller bearings can use oil to cool the rollers, which reduces the temperature rise and thus increases the allowable speed. [0003] At present, the bearing industry generally adopts the off-line sawing method for blanking, which has the advantage of flat fracture, but because the material needs to be manually measured by tools, and then cut by a grinding wheel cutting machine, the blanki...

AI Technical Summary

Problems solved by technology

[0003] At present, the bearing industry generally adopts the off-line sawing method for blanking, which has the advantage of flat fracture, but because the material needs to be manually measured by tools, and then cut by a grinding wheel cutting machine, the blanking cost is high and the work efficiency is low. After the materials are put into the bearing heating forging production line in turn, the materials need to be prepared in advance, and the loss of raw materials is large;

[0004] In addition, the temperature control of the forgings on the bearing forging production line is not accurate. During the production process, some overheated or underheated workpieces flow into the workstations, which cannot guarantee the safety of the operation, and the quality of the forgings is uneven.
