Abstract

PURPOSE:To exchange a die without stopping a rolling line by detachably attaching plural dies, used for edging a steel material, to a rotatable die holder and pressing a prescribed die against the steel material. CONSTITUTION:In edging a rolling material, a prescribed die 13 is stopped at the front of a plunger 17 by rotating a die holder 7 with the aid of a driving shaft 19, and the plunger 17 is advanced by feeding a pressurized oil to a cylinder 16. The die 13 is advanced together with a piston rod 12, which is pushed by the advancing plunger 17, to perform the edging of the material. After edging, the plunger 17 is returned to the original position, and the die 13 is retreated by feeding the oil to an oil chamber 14 and is housed in a housing hole 15. In case of changing the die 13, the holder 7 is rotated by the shaft 19, to stop the die 13 to be exchanged at, for instance, a prescribed position at the upper side and detach the die 13, together with a die assembly 9, from an attaching hole 8 through a prescribed foothold. Next, an assembly 9 with a previously-set new die 13 is fitted and fixed to the hole 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a width compression device that allows easy replacement of molds.

[Prior Art 1] In the conventional width press, when replacing the M4'1M clay mold, the rolling line had to be stopped, and therefore there was a problem that production efficiency was reduced.

[Object of the Invention] An object of the present invention is to provide a width compression device that allows molds to be replaced without stopping the rolling line.

[Y5 light configuration] The present invention is a rotatable mold boulder, in which a plurality of molds capable of compressing the width of the steel material are removably attached. A pressing device is installed to press the steel material against the widthwise side ends of the steel material.Therefore, it is no longer necessary to stop the rolling line when changing the mold, which improves production efficiency.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

The left and right frames 1 installed on both sides in the width direction of the rolled material are connected by tie bolts 4.5 through spacers 2.3, and each frame 1 is equipped with a mold via a bearing 6 at the part 2 where the space is visible. A holder 1 is rotatably fitted.

A mold assembly mounting hole 8 is bored in the circumferential direction of the mold holder 1 with appropriate bits, and a mold assembly 9 is inserted into the mounting hole 8.
is attached to @dose 11L. The mold assembly 9 is the third
As shown in the figure, it is composed of a casing 10, a cylinder 11 fixed in the casing 10, a piston rod 12 slidably fitted into the cylinder 11, a mold 13 fixed to the tip of the piston rod 12, etc. By supplying pressure oil to the oil chamber 14 in the cylinder 11, the mold 13 can be stored in a mold storage hole 15 provided in the casing 10.

A cylinder 16 is installed on the outside of the left and right frames 1, and a plan cylinder 1 stored in the cylinder 16 is installed.
7 is guided by the tip of the cylinder 16 and the guides 18 and 18' installed on the frame 1, and passes through the C frame 1.
A mold 13, which is attached to the lower part of the mold boulder 7, can be pushed in the direction of the rolling profit margin. Further, a hydraulic cylinder 22 is attached to the rear of the cylinder 16 for returning the plunge ν'-17 to its original position.

A prime mover 19 with a brake is disposed on the upper part of the frame 1, and the output shaft of the prime mover 19 meshes with a gear V-20 carved on the rear outer periphery of the mold holder 7.
A pinion 21 is fixed to rotate the pinion.

When compressing the width of the rolled material, the original m) J [19 is driven to rotate the mold holder 7, a predetermined mold 13 is stopped in front of the planer 17, and pressure oil is supplied to the cylinder 16 to reduce the planer. Move jar 17 forward.

Therefore, the plunger 17 moves forward and the piston rod 1
2 (as a result, the mold 13 advances and the width of the rolled material is compressed. At this time, the oil chamber on the piston rod side of the hydraulic cylinder 22 and the oil chamber 14 of the cylinder 11 are communicated with the oil tank. Therefore, the piston rod of the hydraulic cylinder 18 moves together with the plunger 17, and there is no problem with the movement of the mold 13.

After width compression, the plunger 17 is returned to its original position by the hydraulic cylinder 22, and the mold 13 is retracted by supplying pressure oil to the oil chamber 14 and stored in the mold storage hole 15.

When replacing the mold 13, the prime mover 19 is driven to prevent the mold ij-ruter 7 from rotating, and the replacement rivet (W2B) is stopped at a predetermined position, for example, on the upper side, and placed on a predetermined scaffold (I! Remove the mold assembly 9 together with the mold 13 from the mold holder 1 from the hole 8 of the mold holder 1, and insert the mold assembly 9 with the new mold 13 into the mold boulder. -1
Fit into the silk three-dimensional hole 8 of the mold and fix it. Mold 1
Since another mold 13 is located in front of the plunger 17 even when replacing the material, there is no problem in compressing the width of the rolled material.
There is no need to stop the rolling line.

Ctd3, the embodiment of the present invention describes the case where the mold assembly is replaced with the casing, and Iζ is the cylinder, piston rod 1 to . Even if I try to replace only the mold, or change the piston loft to gold? It is also good to replace the mold, and the press and release of the mold is not limited to the cylinder mechanism, but also the link Isosu, cam mechanism, etc. can be used. The inflow and outflow of fluid is also controlled by hydraulic pressure (several (
J-Crab Slurry 1-/]-Tut mechanism, 7J-mu structure, etc., and can be applied not only to rolled materials but also to various steel materials, and in addition, within the scope of not departing from the gist of the present invention. Of course, various changes may be made.

[Effect of the Invention 1] According to the width compression device of the present Komei, there is no need to stop the rolling line when changing molds, so that production efficiency is not reduced and efficient work can be performed.
