at present, a crankshaft and a shaft end bearing bush of the existing mechanical press form a sliding friction pair to rotate relatively, and because the structural bearing bush of the existing mechanical press is not provided with a lubricating oil recovery device, the shaft end bearing bush is mostly lubricated by thick oil in an intermittent way, and for the mechanical press with lower crankshaft rotating speed or low mechanical performance requirement, the requirement can be basically met by the thick oil in the intermittent way, but the requirement cannot be met for the high-speed and precise mechanical press or an automatic production line. As shown in fig. 18 and 19, the structure of the existing mechanical press is schematically illustrated, the crankshaft includes a crank throw in the middle and support shafts disposed at both ends, the support shafts at both ends of the crankshaft are mounted in shaft end brasses, and the shaft end brasses are mounted on the frame through support sleeves. The crank throw in the middle of the crankshaft is arranged in a connecting rod copper bush, the connecting rod copper bush comprises an upper connecting rod copper bush and a lower connecting rod copper bush, and the shaft end copper bush and the connecting rod copper bush are collectively called as a bearing bush to jointly form a sliding friction pair for the relative rotation of the crankshaft and the bearing bush. The crankshaft slides and rotates in the shaft end copper bush, the connecting rod copper bush is arranged in the connecting rod cap and the connecting rod, and the connecting rod copper bush, the connecting rod cap and the connecting rod are connected together and then reciprocate up and down along with the rotation of the crankshaft.
With the continuous iteration of the technology, some technical problems, such as rapid wear, damage and/or locking between shafts and bearing bushes, are solved primarily by the following invention patents applied by the company: the temperature control device comprises a crankshaft of the mechanical press, an automatic temperature rise control device of a bearing bush (No. CN107097452B), a temperature control device of an eccentric body bush of the mechanical press (No. CN109695635B) and a temperature control precision lifting device of the forging mechanical press (No. CN 110538956B).
However, in the practical application process, other deep technical problems need to be solved urgently, for example, the thick oil used in the thick oil intermittent lubrication scheme is thick, the lubrication effect of the crankshaft is poor in high-speed and precise rotation, the integral temperature rise of the bearing bush is easily caused, and the improvement of the rotating speed and the precision is restricted. Although some thin oil lubrication systems are adopted, the existing thin oil lubrication systems are not specially designed for lubricating a crankshaft bearing bush, and have a plurality of problems in use, particularly two outstanding problems are solved, namely, firstly, the problem of oil leakage caused by the fact that a gap is enlarged and the sealing effect is lost due to abrasion of a crankshaft shaft end sealing ring caused by long-term high-speed rotation of a crankshaft is solved; secondly, the existing thin oil lubrication system does not have a special waste thin lubricating oil recovery device, which causes oil pollution and has potential safety hazard. In addition, the existing thin oil lubrication system adopts a point to measure the local temperature of the bearing bush, the temperature measurement mode cannot accurately reflect the real temperature rise deformation condition of the bearing bush, and the temperature rise of the bearing bush cannot be effectively and accurately controlled, so that the outstanding problems of unstable temperature control precision, restricted rotation linear speed, serious oil leakage environmental pollution and the like are caused.
