Abstract

The invention discloses a passive high-speed rotary die box. The passive high-speed rotary die box comprises a rotary device mounted in a box body, wherein the rotary device comprises a spiral die, a hollow shaft, a tapered sliding bearing, an oil pipe which is externally connected with a hydraulic station, a second bearing, front and rear covers and a shell, wherein the spiral die is mounted in the hollow shaft; the front part of the hollow shaft is suspended in the tapered sliding bearing; the oil pipe penetrates through the tapered sliding bearing to be contacted with the hollow shaft; the rear part of the hollow shaft is mounted in the second bearing; the front end of the hollow shaft is sleeved with the front cover and is connected with the shell; the rear end of the hollow shaft is sleeved with the front cover and is connected with the shell and the box body. The passive high-speed rotary die box is simple in structure; the tapered sliding bearing which can operate at the high speed and has high bearing capability is adopted and a main stress of a rotary die is borne by the tapered sliding bearing, so that the rotary die is not limited by a rotary speed, the service life is long and the problems that the bearings are replaced usually so as to influence the production and the efficiency are solved.

Description

technical field [0001] The invention relates to the field of production equipment for spiral rib steel wire in the wire product industry, in particular to a passive high-speed rotating mold box. Background technique [0002] Spiral rib steel wire has been popularized and applied in my country for nearly 20 years, and is in great demand. In the production process, the bearings of the passive rotary mold box are easily damaged, and the general service life is about one week, and some are even shorter. Therefore, in order to improve production efficiency, it is necessary to design a reasonable structure of the rotary mold box to solve the problem of actual use. question. In terms of meeting the requirements for the use of the rotary mold box, the device should not only rotate passively and freely at a high speed, with a speed of 4500-5500 rpm or even higher, but also bear an axial force of 10-20KN. Therefore, the carrying capacity of general rolling bearings or sliding beari...
