ッダーの線材剪断装置に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a cutter in which a die block to which a shearing die and a forging die are attached is installed in a header body, and the shearing surface of the shearing die is slid by a reciprocating drive member of the header body. This invention relates to a wire shearing device for a header that shears the wire protruding from a shearing die.

た。Conventional technology and problems to be solved by the invention Conventionally, in such shearing equipment, when changing the product to be manufactured, the forging die attached to the die block was removed and replaced with another one. However, since the replacement process takes time and the setup is troublesome, we prepare a die block with the forging dies that correspond to the product attached in advance, and when changing products, we can speed up the setup by exchanging the whole die block. I was trying to get there.

て、カッターの取付作業に時間を要する欠点があった。However, the cutter, which slides on the shearing surface of the shearing die of the die block, is attached to the reciprocating drive member of the header body, which moves reciprocatingly in parallel to the shearing surface of the header in conjunction with the ram of the header body. Since it is separate from the die block, each time the die block is replaced, an appropriate gap is created between the cutter and the shearing surface, and the cutting edge of the cutter and the protruding hole of the wire of the shearing die are aligned. It is necessary to finely adjust the attachment position of the cutter to the reciprocating drive member as shown in FIG. There was a drawback that the cutter had to be fixed and the work of installing the cutter took time.

行なうことができて生産能率が向上する効果を奏する。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has provided a method in which a shearing die and a forging die are attached to the front surface of a die block which is detachably attached to the header body along the shear plane of the shearing die. A sliding guide is provided, a cutter for shearing the wire protruding from the shearing surface is fitted into the sliding guide, and a connecting portion is provided on the cutter to be separably connected to the reciprocating drive member of the ladder body. The structure is as follows. - Function and Effect The header wire shearing device of the present invention has the above configuration,
Since the cutter is fitted into the sliding guide of the die block before the die block is attached to the header body, the positioning of the cutting blade of the cutter and the shearing die in a direction perpendicular to the movement direction of the reciprocating drive member is possible. Since the positioning can be performed in advance and the cutter slides along the sliding guide with a proper gap between it and the shearing die, the positioning adjustment in the direction of movement of the reciprocating drive member is possible. If you do this in advance, you can simply connect the cutter to the reciprocating drive member, and since the cutter is fitted into the sliding guide and will not wobble when shearing the wire, it will be easier to attach the connecting part to the reciprocating drive member. Therefore, the work of connecting the cutter to the reciprocating drive member can be done quickly, and the setup associated with replacing the die block can be done quickly, which has the effect of improving production efficiency. play.

8 and comes into contact with the stopper 56, and then the reciprocating drive member 50 moves to the right to shear the wire a between the shearing die 5 and the cutting blade 28, and the reciprocating drive member 50 further moves to the right and cuts through the through hole 2 of the cutting blade 28.
7 aligns with the center hole 19 of the abutment die 9, the sheared material is ejected from the cutting blade 28 to the front of the retreating surface 2 by the abutment pin 19a, and the material is held by a gripping mechanism (not shown). The first and second heading dies are held
o, 12 are sequentially transferred to the front surface of the cutter 21, and are hammered and forged by a punch attached to a ram (not shown). Since the height of the hole 27 matches the height of the center hole 26 of the shearing die 5, when the cutter 21 is connected to the reciprocating drive member 50, the through hole 27 of the cutting blade 28 and the height of the center hole 26 of the shearing die 5 are connected. By adjusting the center hole 26 of the cutter 21 so that it coincides with the center hole 26 in the left-right direction, mutual alignment can be easily performed.
