の伸縮量を所望量に一致させる、構成としである。A plurality of forging dies are continuously arranged in a holder, and the plurality of forging dies are held between an elastic means and a pressing means whose pressing force is adjustable from both sides in the direction in which the plurality of forging dies are arranged, In a forging die setting method in which the plurality of forging dies are held in a holder via the pressing means and the resilient means, the pressing force of the pressing means is determined by the sum of the thermal expansion amounts of the respective forging dies at the time of setting. Then, when the amount of expansion and contraction of the elastic means is detected and the amount of expansion and contraction of the elastic means is not a desired amount corresponding to the pressing force of the pressing means, the pressing force of the pressing means is increased. The configuration is such that the amount of expansion and contraction of the elastic means matches a desired amount by adjusting the pressure.

０が取付けられている。1; The total amount of thermal expansion of each of the lower molds 5b to 7b at the time of setting is the amount of thermal expansion of each of the lower molds 5b to 7b at the time of setting with reference to a reference temperature, for example, room temperature (20"C) of the lower mold. The amount of expansion in the same expansion direction is used for the amount of thermal expansion of each of the lower molds 5b to 7b. Preferably, the amount of expansion in the direction in which the plurality of lower molds 5b to 7b are arranged is In addition, in this embodiment, each lower mold 5
In order to determine the amount of thermal expansion at the time of setting b=-7b, the temperature at the time of setting of each of the lower molds 5b to 8b is measured, and the amount of thermal expansion is calculated based on the measured temperature. Therefore, each lower mold 5b to 7b has a temperature sensor 2.
0 is installed.
尚、下型８ｂにも温度センサ２０が取付けられている。Note that a temperature sensor 20 is also attached to the lower mold 8b.

しているのである。The reason why the tightening force of the bolts 14 is set to increase as the total amount of thermal expansion increases is that when the total amount of thermal expansion is large, the tightening force of the bolt 14 is set so that the tightening force increases as the total amount of thermal expansion increases. Since the amount also increases, it is ensured that the clamping force by the elastic means 9 and the pressing means 10 is not insufficient within a certain temperature range.

This allows you to accurately set the pressing force for pressing b.
In a certain temperature range, the clamping force by the elastic means 9 and the pressing means 10 can be set to an appropriate state.As a result, since the clamping force is too small, multiple lower molds are used during molding. 5b to 7b may move due to the load in the direction in which they are disposed, causing a mismatch between the lower molds 5b to 7b and the upper molds 5a to 7a, or the clamping force may be too large, resulting in no remaining movement during expansion. , the popping means 9, the lower holder 1, etc. will not be damaged.

伸縮量を所望量に一致させる。■Next, the amount of expansion and contraction of the first elastic means 9 is detected, and if the amount of expansion and contraction of the first elastic means 9 is not the desired amount corresponding to the pressing force of the pressing means 10, the tightening force of the bolt 14 is adjusted and the elasticity is activated. The amount of expansion and contraction of the means 9 is made to match the desired amount.

The amount of expansion and contraction of this elastic means 9 corresponds to the clamping force exerted by the elastic means 9 and the pressing means lO, and by detecting the amount of expansion and contraction of this elastic means 9, it is possible to determine the desired clamping force at the time of setting. You can decide whether or not to do so.

This means that the clamping force caused by this is not properly set by the setting of the pressing force of the pressing means 10 at the time of setting. This means that even if the bolt 14 is tightened with a predetermined tightening force, the friction coefficient of the wedge member 13
Considering the case where the amount of expansion and contraction of the elastic means 9 does not reach the desired amount because the friction coefficient of the sliding part between the lower mold 7b and the friction coefficient between the lower molds 5b to 8b and the lower holder are different from the predetermined ones. -ing

なる。Adjusting the tightening force of the bolt to match the amount of expansion and contraction of the elastic means 9 to a desired amount means that the clamping force when set by the elastic means 9 and the pressing means lO is essentially Although it is set based on the setting of the pressing force of lO, it means that the clamping force at the time of setting is ultimately determined based on the amount of expansion and contraction of the elastic means 9, taking into account the above cases. As a result, the clamping force can be properly and reliably set at the time of setting, and based on the setting, the clamping force can be set to an appropriate state without excess or deficiency even within a constant temperature range.
