Abstract
Description
- This disclosure relates generally to devices and methods for straightening wound continuous long-length tubing. More particularly, this disclosure relates generally to devices and methods for straightening metal tubing wound onto spools.
- Briefly stated, a portable rotary tubing straightener apparatus comprises a mobile console. A spool mounting assembly is mounted to the console. A motor is supported on the console and drives a shaft which rotates a drive roller. An adjustable tensioner assembly has a tension roller positionable opposite the drive roller. The drive and tension rollers are engageable at opposed locations of a continuous tubing. A rotary straightener assembly is mounted to the console. A second motor is carried by the console and activatable to rotate the rotary straightener assembly. Upon mounting a spool with tubing to the spool mounting assembly and feeding tubing through the rotary assembly and between the rollers and activating the first and second motors, the tubing unwinds from the spool and exits in a continuous straightened condition from the drive and tension rollers.
- In a preferred form, the adjustable tensioner assembly further comprises a pivot arm mounting the tension roller. A variably positionable shaft engages the pivot arm and has a rotary handle. A safety cover has a pair of apertures and encloses the rotary straightener assembly wherein the rotary straightener assembly is disposed between the apertures and tubing is passable through the apertures and the rotary straightener assembly. Upright guides, each having an eye, guide entry of the tubing to the tensioner assembly. The mobile console also has a plurality of wheels. At least some of the wheels have a settable brake.
- The safety cover is secured to the console by a safety latch. A safety interlock switch prevents operation in the event that the safety cover is not locked to the console. The safety cover preferably further comprises a pair of opposed handles to facilitate removal of the cover from the console.
- A control panel has manually operating controls which control the speed of the first motor and the second motor. The rotary straightener assembly preferably comprises an arbor with a plurality of removable pegs.
- The mobile console includes a perforated panel and a ventilation fan for ventilating heat from the console. The spool mounting assembly has an unwinder mechanism which unwinds tubing from a spool mounted to the spool mounting assembly.
