Claims

[Claims for Utility Model Registration] (1) A lower blade is fixed to a fixed frame, and a ram with an upper blade is provided on the fixed frame so as to be able to reciprocate in the front and back direction of the lower blade, and on the back side of the front and rear rams. A shearing machine is provided with a movable frame extending horizontally fixed, and a back gauge is provided on the movable frame so as to be able to reciprocate in the direction of material insertion, and the ram is reciprocated in the front-rear direction of the lower blade to interact with the upper blade. a clearance changing means for changing the clearance with the lower blade; a clearance detecting means for detecting the clearance changed by the clearance changing means; a back gauge moving means for positioning the back gauge in the material insertion direction;
Back gauge relative position detection means for detecting the position of the back gauge moved by the back gauge moving means with respect to the upper blade, and position of the back gauge with respect to the lower blade based on position information from the clearance detection means and the back gauge relative position detection means. A shearing machine characterized by comprising a calculation output means for calculating and outputting the calculation result. (2) The shearing machine according to claim 1, wherein the clearance changing means changes the clearance appropriately according to input material thickness information. (3) The first utility model registration claim is characterized in that the calculation output means includes a display means for displaying the position of the back gauge with respect to the lower blade.
The shearing machine described in section. (4) The calculation output means compares the target value of the material cutting dimension input in advance and the calculated position of the back gauge with respect to the lower blade, and if the two values are different, the 2. The shearing machine according to claim 1, further comprising a comparison calculation section for appropriately moving the back gauge so that the position of the back gauge matches the target value of the material cutting dimension.
