Abstract

PURPOSE:To form grooves for snap ring free from irregularity in working dimension on a work by placing a work between a pair of flat dies and letting raised parts having projected non-slip teeth cut into the work. CONSTITUTION:Projected stripes 18 for working groove are provided on opposed edge faces 16, 17 of a fixed flat die 11. Non-slip teeth forms are cut on the slant raised parts 19 of the projected stripes 18. A work W, such as a pin etc., is placed between the front end of the movable side flat die and the rear end of the fixed side flat die 2, and the head 29 of the work W is brought into contact with the upper face of both dies 2, 11. The axial part 28 of the work W is brought into contact with the edge faces of the both dies 2, 21. The two raised parts 19 are made to cut into the work while preventing slipping of the raised parts 19, and the movable side die 11 is shifted and rotated. In this while, a groove 27 for snap ring corresponding to the projected stripe 18 is formed at the axial part 18.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for machining a snap ring groove on a bottle and a flat die used for machining the snap ring groove.

9. Conventionally, turning was used to process the snap ring groove of the bottle used for the shaft. Not only is it inefficient, but the turning tool is easily worn out, and JI
If the machining dimensions of M11 products are uneven, and if the head is a bottle with a larger diameter than the ring, the chuck 1 for gripping the workpiece should be made larger.
The workpiece can be attached and detached if the closed IIk is not made, but 1 had one drawback. Also, if the groove processing is performed by rolling like a rolling screw.

In the case of rolling screws, the threads formed by the protrusions of the processing die and raised in the troughs of the thread of the workpiece become the crests of the thread, making it convenient for rolling. Yes, but
When rolling a groove for a snap ring on a bottle, a 1!1 on 9 occurs on both hooks of the groove on the workpiece, and if you try to eliminate this heap, strain will be applied to both the die grooves and the die will not touch the workpiece. It was impossible to roll because it did not bite.

Therefore, the present invention aims to provide a method of machining a groove for a snap ring of a bottle, which can be produced with high efficiency and uniform machining dimensions, and which is suitable for mass production, and a flat die suitable for machining the groove. It is something.

Next, illustrated embodiments of the present invention will be described.

To explain tip-loading fIK, this example shows a case where it is applied to a flat die rolling machine, l is a fixed block of the flat die rolling machine, and above the left hook edge is a fixed block. 'N
! A pen-hei dice is removably fixed with a fixture 3. A material guide chute j is provided at the rear of the fixed block l.

A bushing plate 6 is fitted into the W11 base so as to be movable in the left and right direction. Also, behind the fixed Xiohei die is a space! 17 and attached to the hoarder l.

A board 9 is provided. 10 is a movable block, and a movable hook die 1l-fi is mounted on the top of the right edge of the block.
Can be attached and detached with the mounting bracket L-: Fixed and flat die L
A support plate 1 is attached to the front end of 1D with a fixture 1S, and a movable block IO is attached to the front end of 1D with a required viewing distance between the movable die 1''l and the left side of the foot 2 die (support). It is possible to move #g1 in the front-back direction.

At this time, the head part 9 of the workpiece W is in contact with the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the upper part of the work W. is IM-flat dice.

As mentioned above, in the method of the present invention, the workpiece is placed between two flat dies, and then, by relative movement of these flat dies, the non-slip layer of the ridges of the flat dies forms a linear assembly. While getting involved in club work.

Since the workpiece (#lk for the snap ring is formed by rolling the workpiece), it is possible to form the workpiece with high efficiency and uniform machining dimensions, which is different from forming the workpiece by aSS-turning, and is suitable for mass production. In addition, the flat die invented by II & Co has a good grip on the V-ta when in use, and can be successfully used in carrying out the above method.
