Conventional technology Conventionally, in forging machines such as bolt formers and headers, the front part of the machine frame to which a die is fixed holds the material or blank extruded from the die and transfers it to the front part of the next die, and the ram moves forward. There are many structures that are driven into the die with a punch during heading. Materials or blanks are sequentially gripped and transferred to the front part of this die, and when the ram moves forward, the material or blank is released at the moment it is driven into the die by the punch, so that it immediately returns to the front position after forging. An example of a transfer device is shown in FIG.

A rod 9 transmits the driving force for the horizontal reciprocating motion of the transfer device. 10 is a drive frame, 11 is a plurality of transfer claws, and 12 is a plurality of dice. The drive frame 10 is horizontally moved by the horizontal reciprocating motion by the rod 9, and is configured to sequentially move to the front of the plurality of dies 12, and at the same time, a pair of transfer claws are moved by the drive section of the transfer claws.
The front side of the die is driven in the closing direction, and the rear side is driven in the opening direction to nip and transfer the material or blank, and the material or blank is driven into the die by the punch when the ram moves forward. It is designed to be opened and returned to the front position immediately after forging.

Problem to be Solved by the Invention When using the transfer claws 13, 13 as described above, the pair of material clamping parts 14, 14 move in an arc with respect to a straight line passing through the midpoint of the die or punch 16, so that It's just a matter of repeating approaches and departures.
Therefore, when the material is clamped and transferred to the front part of the die, and the material or blank is released and returned to the front position at the moment when it is driven into the die by the punch when the ram moves forward, the material clamping part Since the outer diameter of the punch cannot be moved upward, the timing is adjusted so that the return movement to the forward position starts after the punch has retreated to the point where interference with the punch can be avoided during the return movement of the transfer claw to the forward position. consideration must be given.

In addition, there is also the disadvantage that the material clamping part comes into contact with the punch when it is fully opened, making it impossible to use a large-diameter punch, and there are restrictions on mold design.The head of the punch is shown in Figure 5. It became necessary to deform it in this way, which caused problems that affected durability.

Function In this invention, a pair of transfer claws provided symmetrically on both sides of a straight line passing through the midpoint of the die constitutes a two-point support consisting of an intermediate shaft support and an end shaft support. When the shaft rotated, the transfer claws were driven through their respective arms, and the material clamping portion at one end of the transfer claws moved along a trajectory that first opened horizontally from the clamping position and then escaped vertically. In addition, when holding the material, it moves once in the vertical direction, and then moves toward the horizontal direction, contrary to the above.

A pair of transfer claws 1 are provided symmetrically across a straight line passing through the midpoint of the die or punch, and have a material holding portion 2 at one end. 3 is an intermediate shaft support, which is connected to a drive shaft 5 via an arm 4. An end shaft support 6 is provided at the other end of the transfer claw 1 and is connected to a driven shaft 8 via an arm 7. As described above, the transfer claw 1 is supported at two points: the intermediate shaft support 3 and the end shaft support.

Effects of the invention The transfer claws of the invention are arranged symmetrically across a straight line passing through the midpoint of the die or punch.
By the reversal movement of the drive shaft, it is driven with two-point support by the intermediate shaft support and the end shaft support. Therefore, the material clamping section at one end can move horizontally and vertically, and can repeatedly clamp the material and transfer it to the front surface of the die. The material clamping section moves horizontally near the midpoint of the die, resulting in stable movement without vertical movement, and high-speed drive is possible. In addition, after opening in the horizontal direction, the transfer claw completely avoids the outside diameter of the punch by moving vertically upwards, so at this point, even if the punch is at its most advanced position, the material clamping part It is possible to return to the front position without interfering with the machine, which increases the margin of machine timing, allows for the use of large diameter punches and greater flexibility in mold design, and eliminates the need for punch processing, etc., making it highly durable. The practical effects are great, such as being able to select the mold.
