Abstract

PURPOSE:To provide the titled device which can form a metal plate in different sizes without changing a forming roll by constituting upper forming roll and lower forming roll freely shrinkable and expandable in right and left directions by fitting a spring between a pair of roll half bodies. CONSTITUTION:In the forming roll equipment that a metal plate 3 is passed through between upper forming roll 1 and lower forming roll 2 arranged up and down and is formed in the prescribed shape of groove shape, etc., the above upper forming roll 1 and lower forming roll 2 composing a set roll A are formed between respectively a pair of roll half body 4 at right and left with fitting of a spring 5 to energize in the direction to separate the roll half body 4. As a favorable form, the above a pair of roll half body 4 is fitted freely slidable to a supporting shaft 6 and the spring 5 fitted between the body 4 is arranged on the outer periphery of the above supporting shaft 6 and by a nut 8 set to an external thread 7 thread-united in both ends of the supporting shaft 6, the interval between a pair of the roll half body 4 is adjusted according to the shape of the metal plate 3 to be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a forming roll device for continuously feeding a metal plate and roll-forming the metal plate.

[Background technology] Conventionally, there is a forming roll device in which multiple sets of rolls are arranged in which upper and lower forming rolls and lower forming rolls are arranged one above the other, and a metal plate can be passed between the forming rolls of each set to form a shape such as a channel. It looks like this. However, such conventional products have the disadvantage that only one size can be molded, and if the size changes, the roll must be replaced.

[Objective of the Invention 1 The present invention has been made in view of the above description, and the object of the present invention is to enable molding with the same roll even if the dimensions to be molded change, and to eliminate the need for changing rolls. To provide a forming roll device that does not require many types of rolls.

[Disclosure 1 of the Invention The forming roll device of the present invention has upper forming rolls 1 disposed above and below.
In a forming roll device that forms a metal plate 3 into a predetermined shape by passing a metal plate 3 between the main forming roll 1 and the lower forming roll 2, the main forming roll 1 and the lower forming roll 2 are connected to a pair of left and right roll bodies 4.
It is characterized by having a roll that can be expanded and contracted in the left-right direction with a spring 5 interposed therebetween, and by configuring it as described above, the drawbacks of the conventional example are solved.

In other words, the main forming roll 1 and the lower forming roll 2 are expandable and retractable left and right, and their width dimensions can be changed to enable various types of forming to be performed.

The present invention will be explained in detail below with reference to Examples. A set of rolls A is formed by the main forming roll 1 and the lower forming roll 2, and a plurality of sets of the set of rolls A are arranged in the flow direction of the metal plate 3.

In this example, the rough forming assembly roll A1, the medium forming paper roll A
Three sets of rolls A consisting of two and three finishing forming rolls A are arranged. The main forming roll 1 and the non-forming rolls 2 of each set of rolls A are formed by interposing a spring 5 between a pair of left and right roll halves 4 to bias the roll halves 4 in the direction of separation. A pair of roll bodies 4 are mounted on a support shaft 6 so as to be slidable in the width direction, and a spring 5 interposed between the pair of roll half-rests 4 is arranged on the outer periphery of the support shaft 6. A male thread 7 is threaded in the axial direction, and a nut 8 is screwed into the male thread 7 so as to be freely threadable in the ring direction, thereby fixing the pair of roll halves 4 at a predetermined distance.

When a band-shaped metal plate 3 such as a band-shaped steel plate is fed and sequentially passed through each set of rolls A, the metal plate 3 is gradually welded to 7 ohms and formed into a channel-like shape. At this time, Natsuto 8 is ll! By changing the interval between the roll bodies 4, the dimensions of the object to be molded can be changed. In other words, by tightening the nut 8 against the spring 5 and narrowing the width of the main forming roll 1 and the lower forming roll 2 as shown in FIG. Loosen the nut 8 so that the spring 5 can be formed and the spring 5 can be stretched as shown in Figure 2 (b).
), by increasing the width of the main forming roll 1 and the lower forming roll 2 and feeding the wide metal @3, a wide product can be formed.

[Effect of the invention 1 As described above, the main forming roll and the lower forming roll of the present invention are rolls that can be expanded and contracted in the left and right direction with springs interposed between the pair of left and right roll halves. The width of the main forming roll and the lower forming roll can be changed freely by changing the interval between the halves, and it is possible to freely change the width to form various sizes, unlike the conventional method. Replace the roll every time the dimensions change,
Further, there is no need to prepare many types of rolls.
