性を向上させるように図られている。(Prior art) Generally, in a multi-stage heading forming machine, a plurality of heading dies ranging from coarse to fine are arranged side by side at regular intervals on a die block equipped on the machine base, and adjacent heading dies are arranged side by side at regular intervals. The same number of material transfer chucks as the forging dies are attached to the front of the reciprocating movable frame, and the chucks sequentially transfer the material supplied from coarse to fine forging dies,
Bolts, nuts, or parts of various shapes are produced by forging the above-mentioned materials in stages between each forging die and a forging punch that is disposed opposite to the forging die and moves back and forth with respect to the forging die. It is made to be molded. By replacing the forging die, forging punch, and material transfer chuck, a single forging machine can manufacture various types of molded products, thereby improving the versatility of this type of forging machine.

形状の製品Cを成形することが困難であつた。(Problems to be solved by the invention) By the way, when a product C having a shape as shown in FIG. 3 is forged using a multi-stage forging machine,
Similarly, the material A having the shape shown in Fig. 3 is subjected to the forging process between the above-mentioned forging die and the forging punch in stages as shown in ~, and finally finished in the shape shown in Figure 3. However, the material A is sequentially pressed in each step and gradually work-hardened. Therefore, for example, if you try to perform the forging process leading to ~ in succession, the amount of swaging in the forging process is extremely large compared to other processes, so that the blank B 2 is subjected to work hardening in this process. As a result, cracks D and the like occur, resulting in defective products being molded. Therefore, with one heading molding machine, material A having the shape shown in
It was difficult to continuously perform the forging process shown in the figure to form the product C having the shape shown in the figure.

なつていた。 Therefore, conventionally, when forging a product C having the shape shown in the figure, the forging process is performed using one forging machine to create a blank B 1 (semi-formed product).
was continuously formed, and this blank B1 was once taken out from the forging machine and annealed.
By feeding the blank B1 again to another forging machine, the blank B1 was subjected to the forging steps of ~ to continuously form a product C having the shape shown in Figs. For this reason, it is necessary to prepare at least two heading molding machines, which makes the equipment and the like unnecessarily expensive.

ていた。 In addition, if one attempts to form a product C having the shape described above using a single heading molding machine, a certain amount of blank B 1 (semi-formed product) will be continuously pressed through the heading process as the primary processing. After that, by annealing the blank B 1 and replacing the forging die, forging punch, and material transfer chuck installed in the forging machine, a certain amount of the annealed blank B 1 can be used for forging again. It was necessary to supply the product and perform the following forging steps as secondary processing to form the product C having the shape shown. For this reason, each time a certain amount of blank B 1 is forged, the forging die, forging punch, and material transfer chuck must be replaced as described above, which significantly reduces work efficiency. .

となく連続的に圧造加工することを目的とする。 Therefore, the present invention was developed in a multi-stage heading molding machine that forges the supplied material step by step to form a product of a predetermined shape, and the semi-formed product in the middle of the forging process is temporarily discharged outside the heading molding machine. At the same time,
After subjecting the semi-formed product to a specified intermediate treatment such as annealing, the semi-formed product is equipped with a semi-formed product supply device that supplies the intermediately processed semi-formed product to the forging machine again, so that the predetermined intermediate processing such as annealing is carried out during the forging process.

とになる。 To explain the operation of this embodiment configured as described above, the semi-formed product A formed by forging between the ejecting die 3a and the forging punch 5a installed opposite thereto is transferred to the ejecting die 3a. It will be discharged and taken out of the heading molding machine. and,
After this semi-molded product A is subjected to an intermediate treatment such as annealing, it is again introduced into the supply chute 19 via a suitable supply means (not shown) such as a parts feeder. In this case, the supply chute 19 is removably attached to the mounting position of the material transfer chuck 12 of the movable frame 9 via bolts 20, 20, and the receiving die 3b and the forging at the preceding stage position are controlled by the drive rod 11. Since the chute 19 is configured to be reciprocated with the die 3c, when the chute 19 is located in front of the receiving die 3b at the end of the forward movement of the movable frame 9, the chute 19 is introduced into the chute 19. Then, the lowermost semi-molded product A held by the centering means 21 is pushed into the receiving die 3b by the pushing punch 5b. Then, when the movable frame 9 moves back and reaches its terminal end, the supply chute 19
A holding member 21a provided at the lower end of is opened and moved by a stopper 21c, and a plurality of semi-molded products A are sequentially dropped downward one by one. At this time, as shown in FIG.
A material transfer chuck 12 adjacent to the supply chute 19 is located in front of the chuck 1b, and the semi-molded product A extruded from the receiving die 3b is transferred to the chuck 1.
A pair of left and right chuck claws 12a, 12b in 2
It will be held in between. After that, the movable frame 9 moves forward again to transfer the next semi-molded product I to the front of the receiving die 3b, and also to transfer the semi-molded product that has been pushed out from the receiving die 3b and held in the material transfer chuck 12.

供給することができる。(Effects of the invention) As described above, the present invention uses a multi-stage heading molding machine that forges supplied materials step by step to form products of a predetermined shape. After taking it out of the heading molding machine and subjecting the semi-formed product to a specified intermediate treatment,
Since we have installed a supply chute to feed into the forging machine again, products that would otherwise be difficult to forge without undergoing certain intermediate treatments such as annealing during the forging process can now be produced using two forging machines as before. Since the forging process can be performed continuously with one forging machine without using a forging machine, work efficiency is significantly improved. Moreover, in particular, since a centering means is provided at the lower end of the supply chute, the axis of the lowermost semi-molded product among the plurality of semi-molded products supplied to the supply chute is aligned with the receiving die. The axes of the semi-formed product coincide with each other, so that the semi-formed product can be pushed into the receiving die and reliably fed into the receiving die.
