Conventional balustrades usually consist of a straight upper and lower rail and a plurality of straight vertical rods coupled between the upper and lower rails.

That is, the conventional railing is made only by the combination of the straight members of the steel (rail, vertical rods), so the design is very monotonous and feels dull, and the aluminum material is used to compensate for this, but the aluminum casting also represents only a simple pattern. In addition, there are disadvantages of weak strength, and in order to solve these disadvantages, a pattern member (eg, a pipe, etc.) has recently been applied.

The pattern member may be bent at various curvatures to avoid a straight shape and installed on the linear member, thereby providing a new aesthetic sense, thereby increasing the product value compared to using a conventional linear member.

Conventional handrail pattern rails usually have a curved portion to escape straight lines. The curved portion is bent by manual operation by an operator.

Therefore, since the bending shape of the pattern rail is changed according to the habits of the operator, it is not possible to manufacture a pattern rail having a certain standard and shape.

The present invention is to solve the problems as described above, to provide a railing pattern rail bending machine that can automatically bend the railing pattern rail in a variety of shapes through the replacement of the molding piece for the shape of the railing pattern rail. There is this.

Base plate 10 is arranged at a certain height from the ground through a support, such that the worker can work without bending the waist, and the hole for the installation of the rotating plate 20 is configured.

Rotating plate 20 is a circular plate installed in the hole of the base plate 10 to be rotatable in place and the motor is connected to the bottom. The motor may be directly connected to the rotating plate 20 or may be connected via a power transmission means such as a belt.

The number of revolutions of the rotating plate 20 depends on the quantity of the curved portion 2a of the pattern rail 2, but is controlled by the controller to return to the original position when bending is completed regardless of the quantity of the curved portion 2a. do. The controller determines the rotation speed and the position of the rotating plate 20 based on the angle sensor for detecting the rotational speed of the rotating plate 20, for example, the limit sensor for detecting the position of the rotating plate 20, and the bending When completed, the rotating plate 20 is rotated in the opposite direction as when bending to return to the original position. Accordingly, it is possible to solve the inconvenience and inconvenience that the operator sets the position of the holder 30 to the initial position in order to bend the new pattern rail (2).

The holder 30 is provided with a base material fixing part 31 to which an end of the base material 1 is fixed. The holder 30 is fixed to the rotating plate 20 and rotates together with the rotating plate 20 to fix the base material 1 to the base material fixing part 31. ) Is rotated, it is preferable that the replacement is possible through a bolt or the like so that it can be replaced according to the structure or size of the maintenance or pattern rail (2).

The base material fixing part 31 may be in the form of a groove into which the base material 1 may be inserted as shown in the drawing, and may be any shape in which the base material 1 may be fixed although not shown in the drawing.

Tightening rods 32 may be provided to fix the base material 1 inserted into the base material fixing part 31 more firmly.

The tightening rod 32 is installed in the tightening rod mounting portion 33 or the rotating plate 20 formed in the holder 30 to be rotatable in place and is provided with a cam-shaped tightening portion 32a. Tightening rod mounting portion 33 is formed in the form of a groove in which one side is open at one side edge of the holder 30 is a structure that allows the tightening rod 32 to be inserted.

That is, as shown in FIG. 3, when the base material 1 is mounted on the holder 30, the base material 1 is not restrained by the tightening part 32a so that the base material 1 can be easily mounted, and the base material ( For the bending of 1), the tightening rod 32 is turned to tighten the base material 1 by the tightening portion 32a.

In the figure, reference numeral 32b is a handle for operating the tightening rod 32.

Patterned molding piece 40 is formed in a curved shape to provide a rotation path of the base material 1 when bending the base material 1 to process the base material 1 in the form of a pattern rail (2), the pattern rail (2) For example, a large number is selectively used depending on the curvature and the quantity of the curved portion 2a of the pattern rail 2.

The plurality of pattern forming pieces 40 are connected in series through the hinge 41 to minimize the volume, and the stopper 42 is provided at the end to maintain a constant shape of the pattern rail 2. The stopper 42 may be, for example, an inclined surface. That is, stoppers 42 corresponding to each other are formed at the ends of the patterned molding piece 40, and when the stoppers 42 of the patterned molding piece 40 are in contact with each other, the patterned molding piece 40 is no longer rotated. Therefore, the curvature of the base material 1 can be kept constant. The stopper is similarly formed in the holder 30.

The guide 50 is for bending the pattern rail 2 to a desired shape by guiding the path of the base material 1, and is installed in the base plate 10 at a predetermined distance from the holder 30. That is, the guide 50 supports the base material 1 to maintain the position of the base material 1 when the base material 1 is bent while rotating along the rotating plate 20.

The base material 1 passes through the guide 50 when the base material 1 is bent along the rotating plate 20, and in this case, the guide 50 is installed to rotate in place to minimize friction between the base material 1 and the guide 50. do. That is, the guide 50 may be in the form of a roller, a bearing.

Guide 50 is installed so as to be movable on the base plate 10 so that the position can vary depending on the length of the base material (1) and the pattern rail (2). The movable installation structure of the guide 50 is, for example, a plurality of positioning holes are formed in the base plate 10 so that the guide 50 is fastened to the positioning hole with a bolt or the like, or the rail is provided on the base plate 10. The guide 50 may be formed to be movable on the rail.

The operation of the railing pattern rail bending machine according to the present invention configured as described above is as follows.

When the shape of the pattern rail 2 is determined, the shape and quantity of the pattern forming piece 40 according to the shape of the pattern rail 2 are determined and installed in the holder 30. In the figure, three patterned molding pieces 40 will be described as an example.

After inserting one end of the base material 1 such as flat iron or a pipe into the base material fixing part 31 of the holder 30 and turning the fastening rod 32 in one direction, the base material 1 is formed by the cam-shaped fastening part 32a. One end of the is fixed to the holder (30).

When the base material 1 is set, it is not necessary to arrange the pattern forming pieces 40 in a constant shape. Because the patterned molding piece 40 is arranged in a constant shape by the stopper 42 when the rotating plate 20 and the holder 30 is rotated to bend the base material 1, the curved portion 2a of the patterned rail 2 Because).

When a bending operation is started by operating a switch, positive polarity is applied to the motor to generate a rotational force in the positive direction (bending direction), and the rotating plate 20 is rotated in one direction by the motor. When the rotating plate 20 rotates, the holder 30 rotates together, and the base material 1 is bent because one end of the base material 1 is fixed to the holder 30.

Specifically, the pattern forming piece 40 rotates in the same direction as the holder 30 by the rotation of the holder 30, and the pattern forming piece 40 is fixed by the stopper 42 (pattern rail ( 2) of the curved portion 2a).

Therefore, the base material 1 is bent along the shape of the patterned molding piece 42 while passing through the guide 50 to form a curved portion 2a.

When the processing of the pattern rail 2 is completed, the positive polarity applied to the motor is cut off and the negative polarity is applied to generate the rotational force in the reverse direction (the opposite direction of the bending direction) to the motor, and the rotating plate 20 Rotate in the opposite direction.

When the holder 30 returns to the initial position while the rotating plate 20 rotates, the negative polarity applied to the motor is blocked and the rotating plate 20 stops.

As a result, the bending work of the pattern rail 2 is finished, and when the tightening bar 32 is turned in the opposite direction to the watchful direction in order to remove the pattern rail 2, the tightening part 32a releases the restraint of the pattern rail 2. And, the pattern rail (2) is separated from the holder (30).

As described above, the holder 30 can mount the new base material 1 directly to the holder 30 as it automatically returns to the initial position, and can continuously produce the patterned rail 2.

That is, the pattern rail 2 may be manufactured in various shapes and applied to the balustrade handrail 3 (FIGS. 6 to 8) or to the handrail 4 (FIG. 9), as shown in FIGS. .

1: base material, 2: pattern rail
