A bright surface spring wire quality improvement device

Abstract

The invention relates to a quality increasing device for glossy spring wires, which belongs to a water tank drawing machine. The quality increasing device comprises a cone pulley, a wire inlet die box, a wire outlet die box and a winding reel, wherein the cone pulley is used for horizontally unwinding, traction wheels and positioning wheels are arranged between the wire inlet die box and the wire outlet die box, the traction wheels and the positioning wheels are respectively located on the upper and lower sides of a steel wire, the traction wheels are composed of a plurality of coaxial wheels with the same diameter, the positioning wheels are also composed of a plurality of coaxial wheels with the same diameter, the fixed axes of the traction wheels and the positioning wheels are perpendicular to the axis of the cone pulley, the steel wire from the wire inlet die box is wound on the traction wheels first, the operation direction of the steel wire is changed into the vertical direction from the horizontal direction, then the steel wire is wound on the positioning wheels and then is wound on the traction wheels, the steel wire is repeatedly wound for a plurality of circles and then enters the wire outlet die box from the traction wheels, and the steel wire is drawn and then is wound on the winding reel. The linear primary adjustment of the steel spring wire is realized in a drawing process, so that the difficulty of linear adjustment of the wire outlet die box of the water tank drawing machine is reduced, and the height of a finished spring is reduced.

Description

technical field [0001] The invention relates to a device for improving the quality of bright surface spring wires, specifically for adjusting the linearity of finished products and changing the drawing direction when drawing stainless steel wires, and belongs to the technical field of metal wire processing equipment. Background technique [0002] When the stainless steel wire is drawn in the water tank wire drawing machine, the linearity of the finished product needs to be adjusted to ensure the stability of the customer's processing. At present, when the water tank wire drawing machine produces fine-gauge stainless steel wire, it only adjusts the linearity through the outlet mold box (referring to pinch the top of a circle of steel wire by hand, so that the two ends of the steel wire are parallel when the steel wire hangs freely, and the distance between the two parallel ends of the steel wire is Generally speaking, the shorter the distance, the better the linearity), which...

Problems solved by technology

At present, when the water tank wire drawing machine produces fine-gauge stainless steel wire, it only adjusts the linearity through the outlet mold box (referring to pinch the top of a circle of steel wire by hand, so that when the steel wire hangs freely, the two ends of the steel wire are parallel, and the two ends of the steel wire are parallel. The distance between, generally speaking, the shorter the distance, the better the linearity), resulting in the difficulty of linear adjustment of the stainless steel wire

In addition, the drawing direction in the water tank wire drawing machine is the vertical direction, while the take-up direction is the horizontal direction, and the stainless steel wire is twisted by 90° near the outlet of the finished reel, which affects the linear stability of the finished stainless steel wire
