DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to improving a forming roll device used for manufacturing large lightweight sections by roll forming steel strips or slit steel plates (hereinafter referred to as steel strips). Person in charge,
More specifically, the present invention relates to a forming roll device capable of roll forming steel sections of various sizes.

The conventional roll forming method for lightweight steel sections is to form a κ between upper and lower horizontal rolls and proceed with forming through the material strip within nine calibers. In order to form a caliber of the required shape between the upper and lower rolls, the diameter of the rolls inevitably increases,
The difference in circumferential speed between the part near the center κ and the peripheral part becomes large, which tends to cause defects on the product, and the cost of K1 equipment is high.
In addition, disadvantages such as a longer roll change time are noticeable.To solve this problem, the roll mounting plate, called a base plate or face plate, which has a through hole through which the shaped steel part is passed through, is installed on the left and right roll stands. Busy vertical K with removable K

Roll forming is carried out by supporting nine forming rolls arranged according to the shape of the steel section being formed, and when forming objects of different sizes, κ is a base plate κ roll, and nine rolls are replaced with the base plate. Forming roll devices have been proposed.

However, with this device, a through hole must be formed in the substrate K that is large enough for the formed steel strip to pass through, and the device is designed to place the rolls in a predetermined position, so it can also be used for forming steel sections of different sizes. Can not do it.

In addition, a type of steel has been proposed in which the inclination angle of the side rolls used to form the flanges on both sides of the section steel can be changed, but the range of forming angles is limited by the shape of the through hole, and the side rolls One end of the ring is pivoted to the base plate, so it cannot be used for the bottom of a channel steel or for webs with different lengths.

The purpose of the present invention is to provide a forming roll device for lightweight section steel that solves the above-mentioned problems. left and right slide plates that can be moved backward; a lower edge roll provided on the slide plate; an inner shaft end pivoted on the slide plate;
The outer shaft end is also provided on the side roll holder on the slide plate and is screwed into the nine male screws.The tilt angle adjustment block κ is pivoted and supports the nine side rolls, the center lower roll provided in the center of the lower base box, and the left and right roll stands. The left and right upper edge roll holders, which are movable up and down between both stands at the upper part K, are screwed together with the left and right male screws κ of the Kujo base box, and are attached to the lower ends of the left and right upper edge roll holders that can move forward and backward, respectively.

It is screwed together. Both ends of the male screw 130 are supported by bearings 15K fixed to a side roll holder 14K with a slide plate 4 km installed.When the male screw 13 is rotated, the inclination angle adjustment block 12 moves up and down, and the side roll 9 is moved up and down at its lower end s10. Since it swings around the pivot point 10a, the inclination angle of the side roll can be adjusted. A center lower roll is provided in the center of the lower pace box 2. An upper base box 16 is provided in the upper part of the O-roll stand 1 between the left and right stands so as to be movable up and down.
Top of stand 1 1af) The tip of the screw 7, which is fitted with a female screw κ, is engaged with the upper base box l6, and the upper base box l6 is moved up and down by the rotation of the screw 70.

Inside the upper base box 16, there are adjustment screws l9 provided on the left and right sides of the upper base box 16 for moving the upper edge roll 18 left and right and adjusting the distance between the left and right upper edge rolls l8 and 18. An upper edge roll l8 is rotatably supported at the lower end of a nine-roll holder 21 with a female screw 20 fixed thereto for 19K threading. When the adjustment screw l9 is rotated, the roll holder 21 is guided by the upper guide rail 22 and moves from side to side, moving the upper edge roll 18 toward the center and outward, thereby adjusting the interval between the left and right upper edge rolls l8. be able to.

A male screw 23 is screwed downwardly into a female screw 25 provided in the center of the base box 16, and the tip of the male screw 23 has a truncated bipyramidal surface at right angles to the screw axis. The servant hardware 24 that I held can be removed from the castle (
The inclined surface 24 at the tip of the wedge metal piece 24 is engaged with the reed.
a is a nine inclined surface 21 provided at the lower end of the roll holder 2l;
aK is in contact. Rotate the male screw 23 to attach the wedge metal fitting 24.
When the holder 2l is pushed down, the holder 2l is pushed outward, so it is possible to finely adjust the distance between the left and right holders 21, and therefore the distance between the left and right upper edge rolls l8, as well as reduce the forming load that the left and right upper edge rolls receive from the operational neutralization material strip steel κ. It also has the role of supporting the inside of the kake to prevent it from being pushed inwards and falling down. This wedge metal fitting 24 is customized depending on the product width dimension, in other words, depending on the distance between the left and right holders 2l, and is replaced every time the width dimension changes.

The method of using this apparatus in the case of channel steel forming shown in the following figure is as follows (in order to simplify the explanation, one side of the apparatus will be described).

Since this device has the above structure, this device is installed in the middle of the molding line, and the male segment screw 7 is rotated to move the slide plate 4 forward and backward over the lower base box. The position of the lower edge roll 8 is determined according to the product width.

Next, rotate the screw 17 at the top of the κ stand l,
Move the upper base box 16 up and down to adjust the gap between the upper edge roll 18 and the lower edge roll 8 to the required gap by matching the plate thickness κ of the material strip, and turn the adjusting screw 19 to move the upper edge roll holder 2l forward. The upper edge roll 18 is advanced to a predetermined position above the lower edge roll 8 by retreating.

Next, a nine-wedge shaped hardware 24 prepared according to the width of the product is engaged with the lower end of the male screw 23, and the left and right holders 21 are lowered to contact the inclined surface K of the holder 21 at the inner position of the lower edge roll l8. Necessary If so, the wedge hardware 24 is pushed down and the left and right lower edge rolls 18 are spread outward to finely adjust the gap between the left and right upper rolls.

If the material strip W is passed through after adjusting κ in this way, the flange portion of the material strip W will be pushed by the left and right side rolls 9K while being held between the upper and lower edge rolls, and the desired profile will be achieved. It is then molded into a molded product with a

As explained above, the device of the present invention is a forming roll device assembled with edge rolls and side rolls, so it is different from a forming roll device with upper and lower rolls K. The rolls are smaller, and the circumferential speed is lower. There is no fear of scratches occurring due to differences. The Mayu Edge Roll is different from equipment in which the side rolls are attached to the so-called substrate or molding plate, and is equipped with a slide holder [9] that allows the roll to be removed after passing, so the distance between the left and right edge rolls can be adjusted according to the product size. The bending position of the flange can be changed, and the inclination angle of the side roll for flange bending can be changed freely, and a hole is provided for passing the material strip through, so there is no need for nine substrates or forming plates. Therefore, there is no restriction based on the product size K, and a wide variety of product sizes κ are possible.
Can be used for both purposes, greatly reducing roll change time.
Alternatively, since it can be used as a forming roll in each stage of a forming line, the practical effects such as being able to significantly reduce the need for roll reserve are extremely large.
