Fine adjustment device for die entering angle of wet drawing steel wire

Abstract

The invention relates to a fine adjustment device for a die entering angle of a wet drawing steel wire. The fine adjustment device comprises a rotating seat fixedly connected to a rack of a wet drawing machine, a rotating box body rotationally connected to the rotating seat, a straight-pipe-shaped swinging part suspended in the rotating box body, elastic supporting rods which are connected to the two axial ends of the swinging part respectively and extend in the radial direction of the swinging part, adjusting screw rods connected to the free ends of the supporting rods in a one-to-one correspondence mode and extend outwards in the axial direction of the supporting rods, and adjusting nuts in one-to-one correspondence threaded connection with the adjusting screw rods, and the two supporting rods are arranged on the two sides of the swing part respectively and extend in the opposite directions. The two adjusting screw rods penetrate through the two opposite side walls of the rotating box body respectively and extend out of the rotating box body, the adjusting nuts are connected to the adjusting screw rods outside the rotating box body in a threaded mode, the rotating center line of the rotating box body penetrates through a center hole of the swing part, and through holes for wet drawing steel wires to penetrate through are formed in the two ends of the rotating box body in the direction of the rotating center line of the rotating box body respectively. A locking piece for locking the rotating box body is arranged on the rotating seat.

Description

technical field [0001] The invention relates to a device for fine-tuning the feeding angle of a wet-drawn steel wire. Background technique [0002] At present, during the wet drawing process of some coarse-sized high-strength rubber hose steel wires, the residual stress distribution in the steel wires is uneven due to the uneven force in the mold, and then there are abnormal quality problems such as warped ends and bamboo knots in the finished steel wires; while the wet-drawing machine straightener The ability to adjust thick hose steel wire is limited, which makes it difficult to completely eliminate problems such as warping and bamboo knots in the finished steel wire during work hardening, which in turn affects the quality of wet-drawn finished products and the effect of customer use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for fine-tuning the feeding angle of the wet-drawn steel wire, which ca...
