この発明は、ワークの端部をせ／Ｖ断加Ｉ するせん所
用プレス金型に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] This invention relates to a press mold for a shearing station for shearing/V-cutting the end of a workpiece.
［従来技術］
従来のこの種のせん所用プレス金型としては、例えば第
１図および第２図に示すようなものがある。[Prior Art] Examples of conventional press molds of this type for use in drilling stations include those shown in FIGS. 1 and 2, for example.
下型ホルダ１上にはポンチ３が装着され、下型ボルダ１
と対をなす′昇降自在な上型ホルダ５には、下方に付勢

ている。A punch 3 is installed on the lower mold holder 1, and the lower mold boulder 1
A pad 9 is vertically provided on the upper die holder 5, which is paired with the punch holder and is movable up and down, at a position facing the punch 3 via an elastic body 7 having a downward biasing force. The pad 9 is movable up and down with respect to the upper mold boulder 5 via the wear plate 11 and is held on the upper mold holder 5 by a pad retainer 13.
また、上型ホルダ５の両側部の下面にはワークＷの端部

とでワークＷが固定される。Then, as the upper mold boulder 5 descends, the pad 9 that descends as the upper mold holder 5 descends comes into contact with the upper surface of the workpiece W placed on the punch 3, and the upper mold holder 5
When the elastic body 7 is lowered, the elastic body 7 is compressed, and the punch 3 and pad 9
The workpiece W is fixed with this.
ワークＷが固定された後更に上型ホルダ５を下降さぜる
と、この上型ホルダ５の下降と共に下降していた可動刃
１５とポンチ３とでワークＷの端部がぜん前加工される
。When the upper die holder 5 is further lowered after the workpiece W is fixed, the end of the workpiece W is completely processed by the movable blade 15 and the punch 3, which have been lowered as the upper die holder 5 is lowered.

必要となってくる。In addition, as a result of repeating such crisscrossing/v17i machining, the part where the movable blade 15 comes into contact with the workpiece W in order to fully process the workpiece W, that is, the cutting edge part 16, wears out, and the clearance (clearance becomes extremely low). As the blade grows larger, it becomes necessary to adjust the position of the movable blade 15 and maintain the straw mold.

１５を上型側に適宜方法により取１＝Ｊりる。First, the mold is turned upside down, and with the pad 3 removed from the mold, a red pen or the like is painted on the side of the bonder 3, and one movable blade 15 is attached thereto. After the movable blade 15 has fully contacted the side surface of the punch 3 in this way, the movable blade 15 is positioned by inserting a shim with an appropriate clearance width between the side surface of the punch 3 and the movable blade 15. In this state, move the movable blade 15 to the upper mold side by an appropriate method.

あった。However, in such conventional drill press molds, the cutting edge portion 16 of the movable blade 15 is worn out by repeatedly performing the above-mentioned pre-cutting process, and the clearance t becomes large. Pre-processed work W
Since large burrs are generated in the sheared portions of the burrs, there is a problem in that in order to prevent rust from forming and slipping from the burrs, it is necessary to remove the burrs, which requires a large amount of man-hours.
また、可動刃１５の切刃部１６の摩耗によりクリアラン

うに付勢されている。A cutting blade boulder 17 of a movable blade 15 divided into cutting blades 11 to 17 and a cutting blade block 19 is attached to the lower surface of the upper die holder 5, and a take-out part 1 21 protrudes from the lower part of the cutting blade holder 17. In FIG. 3, the elastic body 23 is numbered on the right side.
Furthermore, the cutting blade block 19 is provided on the right side of the elastic body 23.
is set up. This cutting blade block 19 has the cutters 1 to 1 inserted from the left side in FIG.
Bolt 29 is attached. and cutting blade block 1
9 is movable in the left and right direction with respect to the cutting blade boulder 17 together with the set bolt 29, and the layered moving part 33 and the cutting blade part 16 are urged by the elastic body 23 so that they always come into contact with the side part 31 of the pad 9. ing.

By lowering the boulder, the pad 9, which had been lowered together with the upper die holder 5, comes into contact with the upper surface of the workpiece W. When the upper die boulder 5 is further lowered, the elastic body 7 is compressed, and the pad 9 and the punch 3 are moved together. The workpiece W is fixed.

By further lowering the upper mold holder 5, the cutting blade holder 17 and the cutting blade block 1, which had been lowered as the upper mold holder 5 lowered, are removed.
The movable blade 15, which is divided into 9 and 9, lowers automatically. This lowering causes the sliding part 33 of the cutting blade block 19 and the cutting blade part 16 to
slides downward while remaining in contact with the side portion 31 of the pad 9,
The end of the workpiece W is machined on all sides with the punch 3. The movement of each part due to the rise of the upper die holder 5 after the pre-cutting process is as follows:
This is the opposite of the movement described above.

行なう必要はなくなる。During such preparatory work, the cutting blade block 19 moves while contacting the side part 31 of the pad 9, so the sliding part 33 and the cutting blade part 16 of the cutting blade block 19 are worn out.
Since the cutting block 19 is always urged toward the pad 9 by the elastic body 23, the clearance t is always maintained at an appropriate level. Therefore, it is no longer necessary to perform mold maintenance, which requires a large amount of man-hours, in order to adjust the clearance t, as in the past.

る。FIG. 4 shows another embodiment. It should be noted that the same components as those in the previous embodiment are given the same reference numerals to simplify the explanation. This has pad blocks 35 on the sides of pad 9.
is attached, and the cutting blade block 19 is attached to this pad block 35.
are always brought into contact with each other by an elastic body 23. According to this, when the pad block 35 is worn out, it is possible to replace the pad block 35.

This eliminates the need to spend a large amount of man-hours on adjusting the movable blade and maintaining the straw die.Also, since the appropriate clearance can always be ensured, large burrs, which are the cause of rust, do not occur, which saves a large amount of man-hours. This can save you the work of removing such a large paris, which costs a lot of time.
