Rolling mill equipment for producing pinch pass rolling pull and push cable core with high fatigue value

Abstract

The invention relates to rolling mill equipment for producing a pinch pass rolling pull and push cable core with high fatigue value, which is used for generating radius uniform deformation of the surface of the cable core. The equipment comprises three rollers (1), radius pressure bolts (2), a worm wheel (3), a worm (4), a straight gear I (5), a straight gear II (6), a driving bevel gear (7), a rolling disc (8) and driven bevel gears (9); a worm wheel shaft is hollow, and a cable core penetrates from the center of the worm wheel shaft; the rolling disc (8) is rotatably connected with the wormwheel shaft through a bearing; the three rollers (1) are uniformly distributed in the middle of the front surface of the rolling disc in an angle of 120 degrees; the rollers (1) are suspended on the rolling disc (8) through a roller seat and by the radium pressure bolts (2); the roller shafts of the rollers (1) are provided with the driven bevel gears (9); the straight gear I (5) is also installed on the worm wheel shaft and meshed with the straight gear II (6) for transmission; and the driving bevel gear (7) is installed on a shaft of the straight gear II (6). The rolling mill equipment produces the surface contact pull and push cable core through the method of roller actively rolling, has high production efficiency and uniform deformation of internal and external wires.

Description

(1) Technical field [0001] The invention relates to rolling equipment for producing push-pull cable cores. It can be used to produce radial uniform deformation on the surface of the cable core to achieve the purpose of flat, smooth and compacted cable core surface. It belongs to the technical field of metal product production equipment. (2) Background technology [0002] Drawing on the domestic and foreign production methods of compacted steel ropes (surface-contact steel ropes), the production methods of push-pull cable cores include integral die drawing, roller die drawing, and swaging methods. The overall die drawing and roller die drawing methods have high production efficiency, but the deformation of the inner and outer steel wires is uneven, and the residual stress of the steel wire is large. When the overall die drawing is used for production after the wire is broken, it is difficult to insert the die and consume a lot of energy; In the forging method, the deformati...

Problems solved by technology

The overall die drawing and roller die drawing methods have high production efficiency, but the deformation of the inner and outer steel wires is uneven, and the residual stress of the steel wire is large. When the overall die drawing is used for production after the wire is broken, it is difficult to insert the die and consume a lot of energy; The deformation of the inner and outer steel wires in the forging method is relatively uniform, and the residual stress of the steel wires is small, but the production efficiency is not high
