Description

{Selector for feeder of straightener} of a small-diameter drawing pipe and a round-

The present invention provides a supply table provided at one side of a putting position of a calibrator to assist straightening or straightening of a draw pipe, and a separate selector device is formed around the supply table so as to be tangled The stacked drawing pipes are individually picked up, loaded on a feeding table (basket-type pipe), and loaded into a calibrating machine. This makes it possible to perform a rapid correction operation in a single operation, In particular, since the worker does not forcibly or forcedly pull the drawn-out pipe which is tangled in a state in which a certain warp or curve is generated, it is possible to minimize the deformation or damage of the pipe itself, Which is characterized in that the quality of the product is greatly improved. It relates to the supply selector table.

Generally, in order to obtain various drawn products of the pipe type, one end of the pipe is swaged and then pulled out by a drawing machine. After the drawing process, the end is straightened and straightened using a straightener, .

On the other hand, a pipe pulled out by a pulling machine is warped or curved to draw a curved part in accordance with the working characteristic, which causes the calibrator to perform the circular and pendulum processing.

In other words, the calibrator allows the exfoliation pipe to be subjected to the full-width and full-width calibration by the curved surface of each of the straightening rollers in the process of passing through the two vertical rows of the straightening rollers, So that various kinds of drawing pipes having different diameters can be calibrated.

In the meantime, the above-mentioned calibrator is provided with a separate supply table around the apparatus, so that a draw pipe of about 10 m is inserted into the calibrator, and is smoothly supplied to the calibrator while providing horizontal support.

At this time, the supply table is equipped with a stacking table around it, and a draw pipe, which is conveyed from a drawer through a hoist or a lift, is stacked and stacked to prepare for calibration.

That is, the loading table is formed on one side of the feeding table and laminated with the drawing pipe conveyed from the calibrating machine. The drawing pipe conveyed in this way is, in particular, When they are bundled and transported, they are stacked on the stacking table after being dropped and twisted.

Thus, the small-diameter drawing pipes loaded in a twisted shape are pulled toward the supply table to be put on the supply table for the worker to put into the calibrator, and the draw-out pipes having a length of about 10 m or so are not only heavy in weight, As a form, one worker holding a separate drawing pipe and shaking it and putting it on the supply table causes inefficiency in safety and time, exposure to safety accidents, and so on. In fact.

That is, the directing kicker is formed at a lower portion of the stacking table made of a frame structure, and is formed so as to lightly pivot on the stacked draw pipe without interfering with the empty space of the frame.

In other words, the operation order of the keyers is such that the upper kicker and the lower kicker have different operation orders, and the lower kicker is formed so as to rise when the upper kicker is lowered.

That is, the individual kickers formed respectively before and after the standby basket 40 are alternately raised and lowered (the lower kicker is raised when the upper kicker descends, and the lower kicker is raised when the upper kicker is raised) .

In this case, it is preferable that the regulating kicker has a multistage gear shape having a slope corresponding to a slope inclined toward the calibration table and having a valley and an acid.

It is preferable that the regulating kicker is formed of a hard synthetic resin material so as not to scratch or damage the outer peripheral surface of the drawing pipe.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
