動モータの小型化等が図れる利点を有している。Conventionally, a drum-type running shear has been frequently used as a shear for continuously dividing materials. However, this method has disadvantages in that it is difficult to adjust the blade gap, the rake angle cannot be increased, the shearing load and torque are large, and the mechanism and drum drive motor are large. For this reason, a link two-way shearing machine has recently been considered, and there is a trend towards its practical use. For example, as shown in FIGS. 1 and 2, a main shaft 3 rotatably driven by a motor 1 and a distribution transmission 2 is provided with two types of eccentric shaft portions 4.5 having different eccentric directions. First eccentric shaft portion 4 (eccentric distance R'1
) pivotally supports a frame 7 equipped with an upper cutter 6, and a second
An eccentric shaft portion 5 (eccentric distance R') pivotally supports a tool rest 8 having a lower cutter 6A, and this tool rest 8 is slidably supported by a guide portion 9 of a frame 7. The frame 7 is caused to swing in synchronization with the traveling direction of the material to be divided by a swinging means linked to the main shaft 1, thereby making it possible to perform the shearing operation smoothly. According to this, the gap can be adjusted relatively easily by adjusting the length of the link arm, etc., and it has the advantage that it can be made lighter and the drive motor smaller.

', ) are provided, and connecting links 11,
The swinging mechanism has become complicated, such as by connecting the drive lever 12, the tuning shaft 13, the swinging lever 14, the swinging link 15, etc., and also using the error cutting wheel 16.

A structure in which the frame 7 is oscillated by an eccentric crankshaft 20 connected to the oscillation gear 19 has been considered, but such a oscillation mechanism has problems such as requiring a large number of highly machined parts. There is.

Part 1 of 3. The upper and lower cutter 2
6.26A moves in the cross direction, and the material inserted between the blades can be divided. In this case, the third eccentric shaft portion 38 swings the lever 31 about the support shaft 32 via the connection link 36. This swinging movement causes the frame 27, including the tool post 2B, to move around the pivot link 34.
It swings in the material conveying direction about the second eccentric shaft part 25 via the. In this way, the upper and lower cutters 26, 26A perform linear motion in the shearing direction and swing motion in the material conveyance direction on the same main shaft 26, 26A.
3 at the same time and with a certain regularity. Then, shearing work can be performed on the material by the linear motion, and the blade movement can be performed in synchronization with the material movement speed by the swinging motion, and inter-travel shearing can be performed on a continuous line or the like.
