Abstract

PURPOSE:To prevent welding failure, by providing a caterpillar which can be driven and rotated so that its caterpllar face face-contacts with the side of a web material, between upper and lower press-welding rolls for pressing a flange material of a weld in the welding shape steel manufacturing process. CONSTITUTION:Between upper and lower press-welding rolls 1, 1, four caterpillars 4 are provided so as to sandwich a web material W between them. The caterpillar 4 is constituted so that its caterpillar face face-contacts with the side of the web material W, and also its face contact part is positioned extending from a welding start point to a welding end point. The caterpillar 4 is constituted of sprockets 5, 5 placed at a prescribed interval, a chain member 6 wound round them, and a press-contact plate 7 fitted to the caterpillar face, and in order to receive force in the lateral direction from the web material W, a guide rail 8 of the chain member 6 is provided on the inside. Accordingly, the caterpillar 4 is driven as the web material W advances, and an relief of the web material W in a weld is detained and supported.

Description

[Detailed Description of the Invention] ζO- is an Al manufactured by 11111 Fist Steel Co., Ltd.
In order to hold the web material of the cleaning steel in the srs,
There are 4, o'e regarding the S support device.

Is it because they don't match?

As a measure to prevent ζam chain failure OII, as shown in Part 2 IIK, we have shifted the Yuko to the upper waterfall side of the Kuep support-first part and it has been effective, but even so, the force that tries to escape to Yokotobiki is still effective. There are many cases where the t#JIr is not strong, especially when the quep# is thin.

Poor prayer - age and middle age.

In addition, line support such as ζO is defective! To make up for it.

There is a method of softening the upper Takiyu Kll fixed plate S and restraining the escape of the Kwep material WO, as shown in the ``■ Fixed plate O
Therefore, wear occurs due to contact.

■Seki - Seki 11 requires advanced skill. ■Support soda rule 20
It has drawbacks such as 0 points and the fixed plate cannot be expanded and supported.

At 40, I couldn't stand the situation like Hiro and ζO, and the O8 fishing was tm from the welding point IIk to the welding completion point t.
A supportable welding part support scissors 1 is provided by Sui and Kami.

The S* part support scissor device related to ζO departure@ is equipped with an endless track system capable of one driven rotation between the upper and lower pressure rolls.

The raceway surface should be in contact with the web material o@mrcWi, and t) The milk catalytic part should be positioned from at least the pseudo-fine point to the welding completion point to completely support the web. This is what I did.

Hereinafter, as shown in No. 411, which will be explained based on an embodiment shown in
A total of four endless tracks 4 are placed between the Kuep Sats. The endless track 4 has a track surface made of web material W.
O@IIKIII! When touched, the Owi contact portion is located at least 5ais from the starting point to the S* completion point.

As shown in s1g, the endless track 4 consists of a sedge socket s, s with a 5f constant interval Ml and a chain wound around it.
#4 and a torsional plate 7 on which a track ItK is attached, and a chain member 60 and a guide rail are provided inside to receive the lateral force from the web material. The sprocket s and the guide rail 6 are attached to a support bracket 9.

In a configuration like ζO, the endless track 4 is
The web #W is completely restrained and supported from escaping in the weld 11 by following the progress. In addition, the above line welding part O
I explained about the support, but without this, the plate material was 0ml/lt.
It is also useful when molding with ff-rules or the like.

According to the key statement O and Shisanko Oji-, the following effects are achieved because the endless orbit supports Ep#.

■ Completely restrains and supports web #O escape in the S* section.
This prevents S contact failure due to heating center misalignment, lower back bending, etc.

■ Because it is very difficult to stack the web material and OII, single-position stacking 9
Zero load is small and parts life is long.

■ Due to the long jI, there is less wear in the corners near the web where the load is strong on If#, and the temperature of the parts increases! You can hold it low.

■ It is inexpensive and does not require high-grade materials.
