Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the development of a manufacturing device for a metal bar with a handle obtained by using a handle roll, and the purpose thereof is to apply vertical vibration to a handle rotating roll to apply a handle, and furthermore, The roll surface is arcuate, and the roll axis is used as a fulcrum to synchronize the horizontal runout with the vertical vibration and press with point support, making it more accurate than conventional products despite the small power mechanism. The idea is to make patterning easier.

To explain the drawings as an example, first of all, in the drawings shown in Figs. 1 and 2, a metal bar 2 is inserted between patterned rolls 1, which are made up of two upper and lower rolls with appropriate patterns on their circumferential surfaces. death,
This roll is designed so that the handle is attached by applying a suitable amount of vibration from top to bottom, and by pressing the roll and rotating it and vibrating it.

In the case of the rolls shown in Figs. 3 and 4, the roll surface has a moderate arc shape, and the patterned rolls 3 with a pattern attached to this arc surface are made into a set of two upper and lower rolls, and each roll vibrates up and down while rotating. At the same time, the roll is vibrated left and right with an appropriate amplitude a using the roll axis C as a fulcrum, and a part of the arc surface of the roll is attached to the metal bar 2 between the rolls by contact, that is, point contact.

The present invention provides a method for attaching a handle to a metal bar by rotating the handle roll 1 while vertically vibrating it as described above, and a handle roll 3 in which the peripheral surface of the handle roll 3 is formed into an arc shape and a handle is attached to this. In this case, the metal bar 2 is attached to a handle by a rotating handle roll 1 that also vibrates up and down, but since the roll handle surface is arc-shaped with respect to the metal bar, the handle is attached by point contact. It goes without saying from a mechanical point of view that since it is attached to a handle, it can achieve the same effect as strong pressure regardless of whether it is a small force. It is designed to oscillate horizontally at an angle a to the left and right, corresponding to the roll rotation speed and in synchronization with vertical vibration, etc. This allows the handle to be attached to the metal bar evenly over the entire width. Moreover, it is an ideal pattern attaching device that can be easily and precisely performed, and can sufficiently exhibit the so-called low-energy effect.

Although the drawing shows the pattern attached to two sides of the metal bar, it is of course possible to attach the handle to four sides at the same time, and the metal bar is designed to be able to attach the handle to round or other appropriately shaped bars, regardless of whether it is square or square. Of course.

Claims (1)

[Scope of Claims] 1. In an apparatus for attaching a pattern to a metal bar by clamping pressure of a set of two upper and lower patterning rolls each having an appropriate pattern engraved on the circumferential surface, vertical vibration is applied to the patterning roll. An automatic handle attaching device for a metal bar is characterized in that the handle can be attached easily and accurately with little force by vibration and rotation, and moreover, the handle can be attached continuously. 2. In a device for attaching a handle to a metal bar by the clamping pressure of a set of upper and lower handle rolls, each of which has an appropriate pattern engraved on its circumferential surface, the handle roll surface is arcuate and the entire surface of the handle is patterned. Two handle rolls (upper and lower) vibrate and press both sides of the metal bar while rotating, and this rotation causes both rolls to tilt left and right and rotate slightly with the roll axis as a fulcrum. An automatic metal bar patterning device characterized in that patterning can be easily and accurately and continuously performed by point contact with the roll arc surface.
