Description

Die mounting jig for Rotopro type rack rolling machine {JIG FOR INSTALLING DIES OF ROTO FLO TYPE ROLL FORMING APPARATUS }

The present invention relates to a jig for easily mounting the dice of the rotopro type rack rolling machine.

Roll forming is a type of plastic working, and it is a processing method of forming using rolling dies without cutting metal or the like. Rolling can be used to precisely engrave the shape of the rolling die on the surface of the workpiece.

Rolling dies used for rolling processing can be roughly divided into two types. One is cylindrical dies and the other is rack dies or flat dies.

The cylindrical rolling die is formed by placing the workpiece between the rolling dies and rotating the rolling die while pressing the rolling die to the target machining size. If the cylindrical rolling die is used, a long round bar-shaped workpiece can be rolled continuously along the longitudinal direction.

The plate-type rolling dies are formed by placing a workpiece between a pair of opposing rolling dies and moving the pair of rolling dies to face each other along the longitudinal direction. If a flat-type rolling die is used, it is possible to precisely process screws, splines, serrations, and the like.

In a rolling machine using a cylindrical rolling die, rolling is performed while moving the rolling die by using a device that pressurizes and moves the rolling die. However, in a rolling machine using a flat rolling die, the distance between the opposite rolling dies is fixed. Forging is done Therefore, in order to adjust the machining dimension or machining tolerance, the protrusion height of the facing rolling dies must be individually adjusted.

The present invention relates to a mounting jig capable of easily mounting or replacing a dice of a flat-type rolling dice.

On the other hand, even in the case of a rolling machine adopting a flat-type rolling die, it can be divided into a vertical type of a counter flow machine (Counter Flow Machine) and a horizontal type of rolling machine roto-flow machine (Roto-Flo Machine).

The present invention particularly relates to a die mounting jig mounted on a Roto-Flo Machine, which is a horizontal rolling machine.

In the horizontal rolling machine, the slider beds extending in the horizontal direction are arranged to be spaced apart in the vertical direction, and the sliders are provided on a pair of slider beds spaced apart in the vertical direction, respectively, and the slider can be moved in the horizontal direction along the slider bed. A dice assembly provided with a rolling dice is fixed to the slider and moved in the horizontal direction together with the slider.

At this time, the lower rolling die is directed upward, and the upper rolling die is directed downward.

On the other hand, the rolling die should be replaced frequently depending on the product to be rolled. In other words, it is often necessary to separate the used rolling dice and install a new rolling die.

In the process of replacing the rolling dice, the lower rolling dice is not mentioned, and the upper rolling dice is very dangerous in its installation in that it may cause an accident if it falls to the lower part.
