Abstract

PURPOSE:To improve the accuracy and yield of products by providing an eccentric shaft on the outlet side of a movable frame and by disposing a pilot work roll coaxial with the eccentric shaft and capable of shifting up and down. CONSTITUTION:The eccentric shaft 15 is provided adjacent to and parallel with the work roll 3 on the outlet side of the movable frame 1 and that shaft end 13 is fixed on a clamping facing of a fixed frame 6 to enable to control the position of the eccentricity. Then, the pilot work roll 4 is formed coaxially on the eccentric shaft 15. After controlling an interlocking value between the upper and lower work rolls 3, 8 by leveling control handles 10, 11, the shaft end 13 of the roll 4 is controlled to enable to give an upper camber or a lower camber. A work P is leveled its existing strain by the work rolls 3, 8 and then a required upper camber or lower camber is given. In this way, the working accuracy and yield of the product to be press-worked is improved.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is capable of plastically deforming a coil material to be straightened depending on the pressing force to J-warp or [as appropriate to the warp, and then feeding it to a mold such as a press machine. Leap on the leveler.

(Prior art) Usually, a plate material rolled into a coil after about 1' of rolling, I
! 1: The coil material itself has an 8m warp due to non-uniform stress during processing and the difference between the outer diameter and inner diameter of the coil, so the coil material to be straightened is placed in a press mold. In order to feed, it is necessary to eliminate these correction factors before adjusting the accurate feeding pitch of the coil material and the iEL crystal.
Therefore, the conventional 5! As a device to eliminate the S+E factor, a device in which the upper and lower work rolls are arranged in a row, that is, a leveler is used, and in particular, the X+I° ability of this type of leveler requires a large number of work rolls installed. There is something to be desired.

(Problem to be solved by the invention) In this way, levelers that have been known for a long time are:

Normally, the curl of the coil material is straightened, the f-shape is straightened, and the plate is made into an r-river, and then fed to the press mold for pressing.
In the current pressing process, is it possible to make the coil material rounder? V
Corrected by the number of work rolls
The products were warped and had dents, and defective products were often produced, resulting in poor yields.

(Means for Solving the Problems) Since the present invention has been made to solve the problems mentioned in 1-, the gist of the present invention is to press the coil material to be straightened at to correct? ! In a leveler with a fixed frame and a fixed frame, there is a W row adjacent to the work roll on the exit side of the straightened I + - coil material of the IJr dynamic frame. is provided with an eccentric shaft, one shaft end of the eccentric shaft extends through the fixed frame and is connected to a rotation adjustment means provided on the fixed flannel, and is coaxial with the eccentric shaft, IR motion frame 1. Work 17 - Separate from ``6 to h
The leveler is characterized in that it has a pi 17 ttwirr [7-] which makes the deviation = r function in F.

(Function) Of movable frame and fixed frame? The coil material to be straightened is pressed downwardly by the work roll of vIt, and then straightened 11, and further II) Wave fringes 11 of the dynamic flenometer:
A pilot work roll coaxial with the 1-8 axes, which is installed in parallel adjacent to the workpiece 17- on the coil material exit 11 side, provides a good JP hold with a high amount of additional ball according to the press machining process. In order to efficiently apply the product, the coil material is appropriately forced to be warped or dewarped [plastically deformed according to the required angle of 1° (example). Therefore, in the following 1. The details of the present invention will be explained based on illustrated examples.

(Effects of the Invention) As described above, according to the present invention, a movable frame and a 1^1 fixed In a leveler having a frame, an eccentric shaft is provided in parallel in contact with the work roll r4 on the side of the coil village 11 to be straightened of the nr moving frame 1, and one shaft end of the eccentric shaft is attached to the fixed frame. , Ii inserted into and extended from the fixed flane.
A pilot work 17- is connected to the stage and is coaxial with this eccentric shaft, and is movable in a manner different from the work 17- of the movable frame.
Since the straightening coil material is provided with a straightening hole, the straightening +E effect of the straightening coil material is synergistically enhanced in conjunction with the plurality of workpiece holes of the movable frame E, and in particular, the straightening degree of the coil material is increased by pressing [and molding]. It can be plastically deformed into f/me 1-1 warp or to warp depending on the temperature, and can efficiently produce products with a high yield and a high degree of press machining. In addition, the horizontal path is 1ffl lt'-"C" operation is easy and the gJ manufacturing cost is low.
