Abstract

PURPOSE:To form projected lines having lateral grooves to a rotary disk at high accuracy and in a short time by bringing a knurling tool having many projections into contact with the outer peripheral face and a die tool having >=1 grooves on the outer peripheral face to the outer peripheral face of a rotary disk under pressure. CONSTITUTION:A knurling tool 7 having many projections on the outer peripheral face that synchronizes with a rotary disk 3 for manufacturing short fibers by a pendant drop method is rotated through a pinion 22, a coupling shaft 18, a uniform speed universal joint 17, a knurling shaft 14, etc. While rotating, the tool is brought into contact with the outer peripheral face 4 of the rotary disk 3 under pressure through an eccentric ring 13 to form lateral grooves 2. A die tool 9 having one >=1 grooves on the outer peripheral face is mounted to a tool shaft 26 allowing free rotation. A screw shaft 31 is rotated by a handle 30, and the die tool 9 is brought into press-contact with the outer peripheral face of the rotary disk 3 through an arm 29 to provide projected lines 6. Repairing and regrinding of the lateral grooves 2 and projected lines 6 can also be performed by above- mentioned tools.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a knurling tool and a die tool. *
The present invention relates to a method for forming a rotating disk for producing short fibers by means of pendant molding, and a device for forming the same, in which protrusions having * can be efficiently and precisely formed into a KiE shape on the outer circumferential surface of the disk.

For example, as shown in *4m1KN, a horizontal 111 corner is formed on the outer circumferential line of a rotating disk (1) with excellent cooling properties, and the outer circumferential surface (4) is melted with metal. material(
a) The molten material (m
) is attached to the protrusion (6) and coagulated, and the coagulated body is peeled off in the normal direction from the outside of the rotating disk EI1mi441 by centrifugal force, thereby forming the lateral groove 111 (!l leap length short fibers ( A manufacturing method for producing b) is disclosed, for example, in Japanese Patent Publication No. 52-228118, and a fibrous i is produced from the molten material (a) using a rotating disk (!).
The method of manufacturing Ik#f pendant drop is called ff5tL. However, the horizontal grooves (l) of the rotating disk (3) have conventionally been machined by indexing each time using, for example, a so-called indexing machine that can regularly position the workpiece at a constant angular pitch. However, the pendant drop method requires a great deal of effort to roll and form molten materials such as metals. (a) and the rotating disk ill are always in contact with each other and rotate, so the outer circumferential surface 14) of the rotating disk 1$1 is easily worn out. When a triangular protrusion (-) with a pointed tip is provided around the circumference, it is usually 10
The protrusions 113 are worn out during actual work for about 30 hours, and re-sharpening becomes necessary. At this time, conventionally, the single-turning disc [31] is removed from the device, and at the same time, the protrusion (@) of the rotating disc is ground using an appropriate grinding tool, and at the same time, the 1 m horizontal distance is removed using an indexing machine or the like as described above. Because it had been shaped, repair and re-grinding required a large amount of rapid opening, resulting in poor work efficiency.

Akira Kishizuku aimed to provide a rotating disk at-type method for producing short fibers and a forming apparatus thereof, which could solve the above problems by using a knurling worker and a mold tool, and the following 701 embodiments are shown in the drawings. I will explain based on this.

By rotating the handle and moving the arm forward, the molding tool 111) comes into contact with the outer periphery 1 [14], and a portion of the molding tool 111 can form a pointed protrusion (61) at the tip.

Furthermore, by performing a combined finish and degreasing, protrusions (91) having lateral grooves (!1) separated by a predetermined pitch ip can be formed on the outer circumferential surface (4) of the rotating disk (set). As a result, as mentioned above, short fibers (-) with a length approximately equal to the length of the K-circle pitch (p) are melted, and the strands (~) of the protrusions (-1) are melted.

The Jt machining time can be shortened, work efficiency is improved, and highly accurate finishing is possible.The low left tool always rotates in synchronization with the rotating disk, so the phases of the protrusions match, making shaping work easier. It can be done. In the present invention, as a tool, for example, a full-form nomite may be used to form the protrusions during initial molding, a grinding roll may be used, and a rotating disc may be used as a mold tool.

It is also possible to use a so-called rolling roll for shaping the protrusions. In addition, the knurling tool can be used as a means for bringing the tool into contact with and separating from the rotating disk, and in addition to the round tool shown in the above embodiment, various uniform tools can be used. When pre-installed in the shaping machine, it is possible to always align the position correctly and form the protrusions with horizontal grooves with high accuracy (for example, it is possible to form the protrusions with horizontal grooves with high precision). It can be particularly suitably used for forming disks.
