超硬合金製ポンチが使用されている。2. Description of the Related Art Conventionally, a squeezed and squeezed can body used for a carbonated beverage can, a beer can and the like is manufactured as shown in FIG. The cup-shaped molded body formed by drawing a tin-plated steel plate (tin plate) or an aluminum alloy thin plate is re-drawn and ironed, and then taken out from the punch 31 and sent to the next step. In FIG. 3, 31 is an ironing punch, and 32a, 32b, and 32c are ironing ring dies, respectively.
Forming 2. The cup-shaped molded body is re-drawn by a re-drawing die (not shown) located on the left side of FIG. 3 and a punch 31 and then ironed in order by the dies 32a, 32b, 32c and the punch 31 to remove the body wall portion. The squeeze-ironing can body 30 is formed with reduced thickness and increased length. Next, the claw portion 33a of the stripper 33 supports the open end portion 30a of the can body 30, and the punch 31 moves in the direction of the arrow X so that the can body 30 is punched by the punch 3.
Extracted from 1. In such a severe working method, the specific portion (A in FIG. 3) of the parallel portion of the punch is worn out severely. The damaged portion A is formed by being removed by repeated ironing. If the damaged portion A becomes large, the punch cannot be used.
Furthermore, it is said that the punched surface has a roughened surface for ironing, but it is said that the punch body has better moldability, but on the other hand, it is difficult to pull out the can body and it is difficult to pull out the can body. There is a problem that breakage easily occurs. For this reason, the punch is usually made of cemented carbide with a smooth lapping surface, and that is not enough to form a pool of cooling lubricant (a minute recess on the punch surface). There is.

難になると考えられる。V-shaped linear grooves and conical recesses have been proposed as the shape of the lubricant reservoir, but the cans used in carbonated beverage cans, beer cans, etc. can be squeezed. The punch used for ironing is made of cemented carbide, which is a brittle material, and the process of providing a reservoir for the lubricant is not preferable because it causes cracks in the punch. When the drawing-ironing process is continued, the punch wears and the lubricant reservoir becomes shallow. For this reason, it becomes increasingly difficult to pull out the can body, and it is necessary to repeat the process of providing a reservoir for the lubricant. In order to reduce the cost in the future, it is required to increase the ironing ratio of the can body to reduce the wall thickness of the can body, and it is considered that it becomes more difficult to remove the can body.

としている。A first technical object of the present invention is to solve the above-mentioned conventional problems and to provide a punch for ironing, which is excellent in the ability of extracting a can body without providing a lubricant reservoir. Further, the present invention is excellent in resistance to change in punch surface profile due to wear, has a longer life up to the modification of the diameter of the punch than a conventional punch, and improves the extractability during the life. The second technical problem is to provide a punch that does not need to be reprocessed.

易に製造することができる。When the punch for ironing of the present invention is used for squeezing and ironing of carbonated beverage cans, beer cans, etc., the cans can be easily removed without causing deformation (rollback) of the openings. Cemented carbide punches that have not been subjected to a coating process will not be picked up due to the adhesion of the metal (cobalt or nickel) contained in the cemented carbide to the steel, tin, and aluminum that make up the can material. However, the TiN, TiCN, and TiC of the film are less likely to cause adhesion and less likely to cause defective extraction, so that a squeezed-ironing can can be easily manufactured.

Usually, a cemented carbide having a hardness of about HRA 90 to 92 and relatively excellent in wear resistance is preferably used. The coating layer 13 has T
Materials such as iN, TiCN or TiC are used. The ironing punch 10 coated with these materials as the outermost layer is excellent in extracting the can body 12 formed by drawing and ironing a tin-plated steel plate (tinning), an aluminum alloy thin plate, or the like. These coating layers 13 do not need to be coated over the entire surface of the ironing punch 10, and contact the side wall portion of the can body 12 (a cylindrical parallel portion excluding the bottom portion of the can body). It only needs to be on the part. This is because this part is subject to great wear during ironing. Therefore, it is not necessary to form a coating layer on the punch bottom portion 14 which is hardly worn. The thickness of these coating layers 13 is preferably 2 to 7 μm. It is preferably 3 to 6 μm. Two
This is because if it is less than μm, there is no abrasion resistance, and if it exceeds 7 μm, the cost increases and the effect is converged if the thickness exceeds this range. Further, these coating layers 13 may be not only a single layer but also a plurality of layers. For example, the base may be coated with TiN and then with TiCN, and any combination of these may be used. For forming the coating layer, various coating forming methods such as CVD and PVD can be applied, and among them, the arc ion plating method is preferable. The outline of this arc ion plating device is shown in FIG.
Shown in In FIG. 2, 41 is a Ti target, 42 is an object to be treated (a target to be coated, a cemented carbide punch in the case of the present invention), 43 is an arc power supply, 44 is a bias power supply, 45 is a reaction gas inlet, 46 Is the outlet.

On the other hand, when a bias voltage is applied to the object 42 to be processed, Ti ions are accelerated and N 2 which is a reaction gas is accelerated.

This is because if the thickness is not less than 0.1 μm, there is a problem in the extractability of the can body. It is preferably 0.070 μm or less.

A cemented carbide punch having a length of m and a length of 190 mm was subjected to a surface smoothing treatment to a surface average roughness of 0.01 μm. Three such punches were prepared, and their sidewalls were each coated with TiN, TiCN, and TiC coatings by 5 μm by the arc ion plating method. After coating, the surface was smoothed until the average surface roughness became 0.06 μm, 0.065 μm, and 0.070 μm, respectively (No. 1 to 3 in Table 1). As comparative examples, a trial was made of a cemented carbide punch that was not subjected to any coating treatment and a punch that was coated with 5 μm of TiN by the arc ion plating method and was not subjected to the subsequent surface smoothing treatment (No. 4-5).

The can body was molded, and the can body was removed from the punch by a stripper. Table 1 shows the results of measuring the deformation occurrence rate at the open end of the can body at this time. Here, the deformation occurrence rate of the opening end means, as shown in FIG. 3, when the opening end 30a of the can body 30 is supported by the claw portion 33a of the stripper 33 and the can body 30 is pulled out from the punch 31, The rate at which the open end of the can body is greatly deformed, and the can body cannot be practically used even after trimming the open end after extraction. The larger this value is, the more difficult it is for the can body to be pulled out.

It can be seen that the can body withdrawal property that can withstand practical use is sufficiently exhibited without applying. In contrast,
Among those shown in the comparative examples, those without coating and without any surface smoothing (No. 4 in Table 1) had a deformation occurrence rate of 48% at the opening end. In addition, a TiN coating was applied but no surface smoothing was applied (Table 1
