Conventionally, a punch having a smooth punch surface has been mainly used as the DI punch, but as a method for roughening the surface, a deep-drawing method such as that proposed in JP-A-49-90668 is used. In order to improve the workability, a method of roughening the punch surface by a grindstone or a mechanical finish, or by ultrasonic processing for improving the extractability as proposed in JP-A-61-209731. A method of forming a recess is used.

の変形、またはクラックの発生の原因にもなる。When a punch having a smooth punch surface is used, it is difficult or impossible to remove the punch due to the frictional resistance between the punch surface and the inner surface of the body of the can, especially when the punching operation is started. Problems such as deformation, early wear of claws, damage to dies, and breakage are likely to occur. When a punch whose surface is roughened by a grindstone or mechanical finishing is used to improve the deep-drawing workability, the punch is improved as compared with the smooth punch, but it is still not sufficient. Further, when the concave portion is formed by ultrasonic machining, contact machining cannot be performed due to wear of the tip.
Moreover, this tendency becomes more remarkable as the chip becomes a brittle material such as cemented carbide. Further, excessive stress is applied to the punch, which may cause deformation of the punch or cracks.

This is a method of processing a DI punch for can making, in which unevenness is formed on the entire surface of the DI punch by irradiating a laser beam of up to 1.06 μm. Further, in the present invention, in the above-mentioned forming method, the diameter of the recess is 1

A laser beam 7 emitted from the laser oscillator 6 is transmitted by a bending mirror 8 and condensed on the surface of the punch 1 by a condenser lens 9. The side nozzle 11 is for spraying a gas such as Ar to a processing point in order to promote evaporation during processing and remove a molten material. Punch rotation device 10
Is rotating at a constant speed, and further, when the condenser lens unit 9 is moved at a constant speed in the punch axis direction, it is possible to process the entire surface of the punch.

２倍波レーザなどがある。At this time, the wavelength of the laser light is 0.53 to 1.
06 μm means that the laser beam having a wavelength of more than 1.06 μm has a low absorptivity, and efficient processing cannot be obtained. This is also because there is no laser having a high peak value and a high frequency that causes an evaporation phenomenon with a laser beam having a wavelength of less than 0.53 μm. Industrially, there are YAG, alexandrite, and YAG double wave laser.

が特に有用であった。Next, FIG. 2 shows a cross-sectional view of the processed punch surface. The hole diameter 12 and the hole depth 13 are controlled by changing the laser power and the focal length of the condenser lens. At this time, in consideration of oil lubrication, the hole diameter 12 forms a large diameter sparsely. It is more advantageous to form the small diameter more densely. In the experiment, 100-200 μm
Was particularly useful.

０μｍ超では、それに対応して缶側の弾性変形量が大き
くなり摩擦も大きくなるためである。The hole depth 13 is set to 1 to 10 μm because it is 1
If it is less than μm, it is not enough to leave the lubricating oil.
This is because if it exceeds 0 μm, the amount of elastic deformation on the can side correspondingly increases and the friction also increases.

である。The height 15 of the convex portion is controlled by changing the pulse width of the laser or the peak value of the laser pulse. At this time, the height 15 of the convex portion is set to 1 to 5 μm if the height is less than 1 μm. This is because it is not sufficient for deep drawing, and if it exceeds 5 μm, harmful scratches are generated on the inner surface of the can.

る。The reason why the area ratio of the unevenness is 5 to 50% is 5
If it is less than 50%, it is not enough to retain the lubricating oil.
This is because if it exceeds%, the contact area becomes large and the frictional resistance becomes large. Pitch 14 is the rotation speed of the punch rotation device,
It can be arbitrarily set by the speed of the condenser lens and the laser frequency.

め均一であり、パンチの変形、クラックも見られない。When manufacturing a long DI punch,
The surface roughness of the DI punch is stepwise from front to back,
Alternatively, by continuously changing, it is possible to improve the extractability while maintaining the deep-drawing workability. For example, by changing the laser frequency and the speed of the condenser lens stepwise or continuously, the DI punch surface is divided into three parts as shown in FIG. 4, the front, the middle and the rear, and the front part with a long extraction distance has a large roughness. By using the motif B, it becomes possible to increase the amount of the oil sump and change the roughness to medium or small as the withdrawal distance becomes shorter, thereby making the motifs C and D.
The punch processed in this manner is uniform because it is processed in a non-contact manner, and no deformation or crack of the punch is observed.
