Abstract
A wire guider includes a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire and an air supply unit for supplying air into the inner path to form a spiral air flow having a current rate faster than a running rate of the wire between an outer surface of the wire and an inner surface of the inner path. Wire Vibration resulting from a thrust force of mill rolls can be damped to more stably carry out one-direction running of the wire and minimize contact between the wire and a guide path. This reduces surface defects of the wire and abrasion of the guide system and protects a sensor unit from damage.

A wire guider of air guide type for guiding a wire which is run in a predetermined direction, comprising:
- a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire, the inner path having an inside diameter larger than an outside diameter of the wire;
- an air supply unit for supplying air into the inner path to form a spiral air flow having a speed faster than a running rate of the wire between an outer surface of the air and an inner surface of the inner path;
- and
- a sensor unit arranged in the guiding unit to inspect the wire, wherein the guiding unit includes an entrance guider arranged at an entrance side of the sensor unit and an exit guider arranged at an exit side of the sensor unit;
- wherein the entrance guider includes an entrance guider body and an entrance screw;
- wherein the entrance guider body has a through hole which the wire passes through, a screw assembling part arranged at a rear end of the through hole with an inside diameter increasing along the running direction of the wire and an air inlet hole communicating with the screw assembling part, and
- wherein the entrance screw has a central hole conforming to the through hole of the entrance guider by, and is assembled to a rear end of the entrance guider body to form an air path communicating the air inlet hole and the through hole between an inner surface of the screw assembling part and an outer surface of the entrance screw body.
A wire guider of air guide type for guiding a wire which is run in a predetermined direction, comprising:
- a guiding unit having an inner path extending along the running direction of the wire to guide the running of the wire, the inner path having an inside diameter larger than an outside diameter of the wire;
- an air supply unit for supplying air into the inner path to form a spiral air flow having a speed faster than a running rate of the wire between an outer surface of the air and an inner surface of the inner path;
- a sensor unit arranged in the guiding unit to inspect the wire, wherein the guiding unit includes an entrance guider arranged at an entrance side of the sensor unit and an exit guider arranged at an exit side of the sensor unit;
- and
- a sensor fixing part arranged between the entrance and exit guiders to fixedly locate the sensor unit,
- wherein the sensor fixing part includes an entrance sensor fixing guider mounted at an entrance face of the sensor unit where the wire enters the sensor unit, the entrance sensor fixing guider having a through hole which the wire passes through, and an exit sensor fixing guider mounted at an exit face of the sensor unit where the wire exits the sensor unit, the exit sensor fixing guider having a through hole which the wire passes through.
A wire guider of air guide type, the apparatus comprising a sensor unit to detect the surface flaws of the wire rod while guiding one-directional movement of the wire rod, further comprising:
- an entrance guider having an inner passage perforated therethrough to have an inner diameter larger than an outer diameter of the wire rod, the entrance guider being provided at an entrance of the sensor unit;
- an exit guider having an inner passage perforated therethrough to have an inner diameter larger than an outer diameter of the wire rod, the entrance guider being provided at an entrance of the sensor unit;
- an air supply unit for supplying air into the inner passages of the entrance and exit guiders, so as to create a spiral air flow having a higher flow rate than a movement speed of the wire rod between an outer surface of the wire rod and inner surfaces of the inner passages perforated through the entrance and exit guiders;
- and
- a cooling water supply unit for providing cooling water between the wire rod and a sensor bore perforated in the sensor unit for the passage of the wire rod, so as to externally cool the sensor bore;
- wherein the exit guider comprises:
- an exit sensor fixing guider having a third through-bore perforated therethrough to allow the passage of the wire rod, the exit sensor fixing guider being mounted at an exit surface of the sensor unit;
- an exit screw member having a center bore coinciding with the third through-bore;
- and
- an exit guiding body having a fourth through-bore perforated therethrough to allow the passage of the wire rod.
