Description

[Detailed Description of the Invention] The present invention relates to a front guard device for a shearing machine.

As shown in FIGS. 1 and 2, the conventional front guard device of this type includes a plurality of round bar-like guard members a attached to the shear body c via mounting members b, and a cutting blade e and a plate holder. This was to prevent hands from entering the dangerous area of device d.

In the shearing work, when performing marking cutting, it is necessary to indicate the position of the cutting blade with a shadow line using a light, and cut the material to be cut by aligning the marking line to be cut with the shadow line.

When performing marking alignment, the cutting edge is watched through the gap between the guard members a of the front guard device, but since the guard members a are fixed and the gap is small, the viewing angle α
was fixed, and his field of vision was narrow and limited.

This made it difficult to match the markings. The present invention was developed in view of the above circumstances, and its purpose is to provide a front guard device for a shearing machine that can widen the field of view during marking alignment and facilitate marking alignment. be.

Hereinafter, the present invention will be explained with reference to FIG. 3 and subsequent figures.

In the drawing, reference numeral 1 denotes a shear body, and a pair of mounting members 2 are fixed to the front surface of the shear body 1, and these mounting members 2 are provided with a plurality of support holes 3 in the vertical direction.

A plurality of flat plate members 4 are attached to the mounting member 2 with shaft portions 5 at both ends thereof rotatably supported in the support hole 3. A lever 6 is fixed to one shaft portion 5 of the flat plate member 4, and the lever 6 is connected to a connecting member 7 by a pin 8 at its end.

A knob 9 for rotational operation is fixed to the shaft portion 5 of one of the flat plate members 4.

In the drawing, 10 is a plate holder, and 11 is a cutting blade.

Then, by rotating the knob 9 and operating the lever 6 via the connecting member 7, the entire flat plate member 4 is rotated, and the inclination angle of the flat plate member 4 is changed in accordance with the viewing angle α, so that the visual field at the time of marking alignment is changed. Expand.

Note that by rotating the knob 9, the connecting member 7 and the lever 6
The flat plate member 4 was rotated through the
The synchronous rotation mechanism A of the flat plate member 4 may be composed of a rack and pinion.

The present invention has been described in detail above, and a plurality of support holes 3 are provided at intervals in the vertical direction in a pair of mounting members 2 fixed to the shear body 1, and a plurality of flat plate members 4 are provided in the mounting member 2. The shaft portions 5 at both ends of these flat plate members 4 are rotatably supported and attached to the support hole 3, and a knob 9 for rotating the flat plate member 4 is provided on the shaft portion 5 of one of these flat plate members 4. ,
Since the flat plate members 4 are connected to the synchronous rotation mechanism A that rotates all the flat plate members 4 synchronously by rotation by the knob 9, the flat plate members 4 can be rotated according to the viewing angle to widen the field of view when marking and matching. can be facilitated.
