る。(Prior technology) The mainstream of conventional continuous forging equipment is the hydraulic press method. (See Japanese Patent Application Laid-Open Publication No. 63-49400) and a single scissor type using a boosting mechanism such as a lever (see Japanese Patent Application Laid-Open No. 61-222663).

グコスト面からも最適とは言えないのが現状であった。In other words, a very large hydraulic power source and piping are required, resulting in a large burden in terms of equipment costs and maintenance.As the pressure is high, the lifespan of the pump and the hydraulic switching valve depend on the usage conditions. It takes only 2 to 3 years, and the noise level exceeds 100 horns, and in the case of a hydraulic system, the electrical energy is converted into hydraulic pressure and transferred from the pump room to the forging device, so the energy loss during this period is 20 to 30 years. At present, it was about 30%, which could not be said to be optimal in terms of running costs.

ある。(Means for Solving the Problems) This invention sandwiches the pass lines of the slab strand drawn from a continuous casting mold at the top and bottom, and by approaching and separating them from each other, the final solidification region of the slab strand during the drawing movement is controlled. In an apparatus equipped with at least a pair of anvils for continuous forging, one of the anvils is disposed within a frame body having an inlet for the slab strand, and the other anvil is formed in the frame body. A series of continuously cast strands, which are fixedly held on a slider that can reciprocate along a guide, and the frame body and slider are each suspended and supported via a link on a crankshaft that controls the mutual approach and separation of the anvils. It is a forging device.

の最終凝固域を連続的に鍛圧加工する。Now, FIG. 1 schematically shows the configuration of a press machine according to the present invention. In the figure, number 1 is the slab strand pulled out from the continuous casting mold, and 2a and 2b are anvils.These anvils 2a and 2b sandwich the pass line of the slab strand 1 above and below, and by approaching and separating from each other, the strand 1
The final solidified area of the steel is continuously pressed.

れに接続したアンビル２ａ。(Function) When the crankshaft 5 on which the frame body 3 and the slider 4 are suspended in a pendulum-like manner is driven by a morph or the like via a reduction gear, the links 3b and 4a are respectively relative to the rotation axis of the crankshaft 5. Since the anvil 2a is eccentric by el+82, it is connected to the frame body 3 and the slider 4 via the frame body 3 and the slider 4.
２ｂはパスラインを挟んで開閉運動を繰返すようになる
。2b repeats opening and closing movements across the pass line.
そしてその間に導かれた鋳片ストランドｌはそれらの相
互接近・離隔によって連続的に鍛圧されることとなる。The slab strands 1 guided between them are continuously pressed as they approach and separate from each other.
ここにアンビル２ａ、 ２ｂの相互接近による鍛圧加工
工程では、装置本体が鋳片ストランドｌの引抜き移動に
帯同して容易に追従できるので設備に無理な力が作用す
るおそれは全くない。In the forging process in which the anvils 2a and 2b approach each other, the main body of the apparatus can easily follow the drawing movement of the slab strand l, so there is no risk of unreasonable force acting on the equipment.

下量は何れの場合であっても同一となる。FIG. 2 shows the trajectory of the anvil 2a during forging as an example, in relation to the feed amount of the slab strand 1 when the crankshaft 5 rotates in the direction of the arrow A. This trajectory specifically shows the cases where the rotational speed of the crankshaft 5 is constant and the drawing speed of the slab strand 1 is increased and decreased (the rotational speed of the crankshaft 5 is (The same is true even if the speed is changed), and anvil 2a has a high withdrawal speed B.
→ B' and C-) C' where the drawing speed is low, but the reduction amount is the same in either case.

で鍛圧中に鋳片ストランド１や設備に無理な力がかかる
うれいがあるが、実際のところ装置本体の追従量はわず
か数１０鵬と短いので振子の長さを少なくとも３ｍ程度
確保しておけば問題はない。It should be noted that while the main body of the device draws a trajectory as described above during the forging process, the drawing movement of the slab strand 1 is horizontal, and at this point, there is a risk of excessive force being applied to the slab strand 1 and the equipment during the forging process. However, in reality, the following distance of the main body of the device is only a few tens of meters, so there is no problem as long as the length of the pendulum is at least 3 meters.

スの範囲内であり全く問題はない。For example, if the follow-up amount d is 30 mm, it is small as shown in Figure 3, and the influence of this inclination on the amount of reduction of the anvil is also small (height displacement δ is 0.2 mm), which is small due to the clearance of the equipment itself. It is within the range and there is no problem at all.
