Description

Piercing device for roll forming system {PIERCING DEVICE FOR ROLL FORMING SYSTEM}

The present invention relates to a piercing apparatus for a roll forming system, and more particularly, a piercing apparatus for a roll forming system that can process holes of a predetermined standard in conjunction with a feed rate on a panel to be fed in a roll forming process. It is about.

In general, a straight beam type is formed by sequentially bending a panel supplied by a roll forming system in which a roll former having an upper forming roll and a lower forming roll is arranged in a row of at least 10 stages or more.

In this roll forming system, as shown in FIG. 1, an uncoiler 101 for releasing the coil 100 is formed in front of a process line, and a strip-shaped steel sheet released from the uncoiler 101 is formed on a flat panel. A straightener 103 extending to 200 is provided at the rear thereof.

In addition, a brake press 105 is provided at the rear of the straightener 103 to form holes for various purposes for assembling and positioning the beams to be formed in the panel 200 supplied from the straightener 103. .

In addition, the roll former unit R composed of at least ten stages of roll formers R1 to R10 (some not shown) is arranged in a row at the rear of the brake press 105 to uncoil the 101 and the straightener. The roll 200 is formed by forming a beam 300 to be obtained by sequentially bending the 103 and the panel 200 supplied through the brake press 105.

However, in the case of the roll forming system described above, the brake press 105 is generally used to process a regular hole on the panel 200 being transported for supply to the roll former unit R, which is a conventional brake press 105. In order to process the hole on the panel 200 being transferred, the piercing speed should be made quickly according to the feeding speed of the panel 200. Accordingly, the size of the press equipment is larger than necessary, so that the installation space on the process line is made. It has the disadvantage of taking wide.

In addition, when the material of the panel 200 is a high tensile strength steel sheet, the piercing speed may cause the blade of the piercing punch (not shown) to be easily worn or broken, or to cause poor quality such as dimensional error of the hole processing portion on the panel. Also implicated.

Therefore, the present invention has been invented to solve the above disadvantages, the problem to be solved by the present invention is to move the position of the piercing punch in conjunction with the feed rate of the panel on the panel to be fed in the roll forming process It is to provide a piercing device for a roll forming system that can process holes of a certain standard, and to simplify the configuration to miniaturize the installation.
