第二段階の加工をしていることが多い。2. Description of the Related Art Gears have been manufactured mainly by cutting until recently, but progress of forging technology has enabled forging and forming. However, the forging industry has undergone a thorough division of labor, and not only the forging process but also other processing processes are performed independently. This also means that the operation of the forging machine is accompanied by vibration, so it is also necessary to isolate it, but because the machining speed of the forging machine and the time required for cutting are too different, it is impossible to operate both machines synchronously. to cause. Therefore, the hot work is hot forged, the work that has been hot forged is temporarily stocked in the passing box 10 etc., and the hot forging device is installed while being put in the passing box 10 every certain unit. From the existing factory to a factory with a cold forging device, where it is heat-treated and bonded to perform cold forging, and then sent to a factory where a cutting device 6 and a polishing device 7 are installed. The reality is that they are cutting and polishing. Due to the nature of the forging industry, even when the forging is repeated twice, the first forging process is not sequentially passed to the second forging process one by one, but the first stage is completed. When several hundred units have been collected, they are collectively moved to the second stage, where the second stage is often processed one by one.

と、そのためにいくつかの弊害が生ずる。When gathering forged workpieces in one place, it is necessary to pay close attention so that the tooth profiles do not come into contact with each other and cause scratches in the case of gears.
A product with a scratch is treated as a defective product. Further, between the hot forging and the heat treatment, and between the heat treatment and the bonder, it is desirable to use the heat of the previous step by sending in before cooling. Further, when the forging is repeated twice, the working heat generated with great care is lost in the stock, so it is necessary to perform a bonder treatment. If the respective steps are dispersed in this way, there are some adverse effects.

Is a heat treatment device, 4 is a bonder treatment device, 5 is a cold forging device, 6 is a cutting device, and 7 is a polishing device. These devices are arranged in series and the transfer mechanism 8.8.
・ It is arranged on the transport route. Heat treatment device 1
Is for heating the material 9 to be fed to the subsequent hot forging device 2, and it is extremely advantageous to provide the material 9 adjacently in terms of thermal efficiency. The heat treatment apparatus 3 performs non-oxidation annealing for the purpose of preventing scale from being generated in the tooth profile and reducing the hardness in preparation for cold forging. By connecting the bonder treatment device 4 and the cold forging device 5 to the heat treatment device 3 in succession, it is possible to reduce the loss of heat energy, increase the bonder effect, and suppress the adhesion of oil and dust and the generation of rust. . The cold forging device 5 is a huge hydraulic cylinder 5a.
Since it is equipped with a fluid pressure type pressurizing mechanism, the generation of vibration is extremely small and the size is small, but conversely, the working time required for one process is several times that of the friction type. In the present invention, on the contrary, it will be described later that it is fortunate.
As the cutting device 6 and the polishing device 7, existing machining centers, shot blasting devices, etc. are used. A robot hand is used for the transfer mechanism 8.8 ...

きる。The production lines are installed in the same building of a factory. According to the gear manufacturing line configured as described above, the raw material 9 cast on the line is processed while continuously undergoing each process, and is successively commercialized. In the line of this embodiment, one hot forging device 2 is distributed to a plurality of heat treatment forging devices 3, and the cold forging device using a hydraulic pressurizing mechanism with a slow processing speed is synchronized with the heat forging device 3. There is. Since the processing speed of this cold forging device is slow, it is convenient to synchronize it with the processing speed of other devices, and since there is little vibration, there is no fear of noise pollution and it can be installed in a small space.

い。With the introduction of the present apparatus, works that have been stocked in the past are sent one after another without being stocked, so that there is no possibility that contact between works will be interrupted and scratches will occur. Even on the same site, the stereotype that the forging device is located in a place isolated from other devices is a thing of the past, and docking the forging device and other devices is likely to become the mainstream. Therefore, the gear manufacturing line developed at the forefront of the role plays a large role.

工に比べて生産性は格段の飛躍を見る。In the embodiment, the device having the transfer mechanism between the respective devices has been described, but the device can also be transferred manually, and the cold forging process excluding the hot forging process can be lined up. It is also possible to do so, and even if a small-scale factory designs the line according to the production amount, the productivity will show a remarkable leap compared to the conventional cutting process.

的発明であるといえる。As described above, according to the present invention, energy efficiency can be improved, and there is no risk of being scratched during movement between devices, resulting in improved yield. In addition, by adopting a fluid pressure type pressurization mechanism in the forging device, it was possible to eliminate the influence of vibration and thereby to line up the production process of forged gears, so it is possible to consistently produce forged products. It can be said that this is a breakthrough invention.
