The utility model relates to a fine wire drawing machine, and provides a multi-stage mold wire jumping prevention type medium-sized fine wire drawing machine, which comprises a base, an equipment main body, a bin gate and the like, an equipment body is arranged at the top of the base, a processing bin is arranged in the equipment body, round holes allowing wires to penetrate through are formed in the left side and the right side of the equipment body, a bin door is arranged on the front side of the equipment body, and the bin door is rotationally arranged on the equipment body and is opened and closed through a movable supporting rod. According to the utility model, the closed lubricating component is arranged on a wire stretching transmission path, and a high-pressure atomization technology is adopted in the component, so that a lubricant uniformly covers the surface of a wire; and in combination with the dynamically adjusted sliding seat, the tension of the wire rod is automatically adjusted, wire jumping, wire breakage and scratches are prevented, the die abrasion and the wire breakage rate are remarkably reduced, manual intervention is reduced, and the high-precision and high-efficiency machining requirements of the superfine wire rod are met.

The utility model relates to the field of fin cooling discloses a fin cooling device for heat exchanger processing, including two rotating holes, two rotating holes all set up in the left side of cooling storehouse, the inner wall of rotating hole rotatablely provided with rotating column, one end of rotating column is fixed with the connecting barrel, the connecting barrel extends to the cooling storehouse, the other end of connecting barrel extends to the outside of cooling storehouse through the connecting pipe, and is connected with the output end of gas conveying equipment, the outer wall of connecting barrel is fixed with a plurality of injection head, injection head is linked with the inside cavity of connecting barrel intercommunication. In the utility model, through the synergetic effect of rotating column, connecting barrel, tooth slot, connecting frame, rack and poking block, the angle of injection head can be adjusted, so that the operator can flexibly adjust according to the different shape, spacing of fin, guarantee that the airflow that injection head sprays can cover the different parts of fin, prevent the phenomenon that fin appears local overheating or cooling deficiency.

The utility model relates to static pressure main shaft technical field, concretely relates to a kind of high-stability rotating mechanism applied to static pressure main shaft, including shell, the inside of shell is provided with shaft, the outside of shaft is provided with oil temperature control mechanism, and oil temperature control mechanism includes the first cooling pipe fixedly connected in the inside of shell, the middle part of first cooling pipe is attached with second cooling pipe, and second cooling pipe is fixedly connected in the inside of shell, first cooling pipe and second cooling pipe are all spiral and the coverage of first cooling pipe is greater than second cooling pipe, and the inside wall of first cooling pipe and second cooling pipe is fixedly connected with heat conduction plate.The utility model cooperates with the cooperation of shell and oil temperature control mechanism, by setting first cooling pipe and second cooling pipe, both are spiral and the coverage of first cooling pipe is greater than second cooling pipe, cooperate heat conduction plate, can increase the contact area with the lubricating oil in oil guide pipe, improve heat exchange efficiency.
