The technical scheme is as follows: the utility model provides a high strength board lower mould of bending convenient to adjust, its includes that longitudinal section is the die holder of U type, the inboard of die holder corresponds the both sides wall and is provided with respectively inserts, insert and make by the die steel that hardness is greater than or equal to 58HRC, two arc chamfer, its characterized in that have been processed respectively to the top inboard of inserting: it still includes stud, stud passes perpendicularly the both sides wall and two of die holder insert, stud is located convex chamfer below, stud with the both sides wall of die holder rotates to be connected, two insert respectively with two sections screw thread screw-thread fit of stud, two sections screw threads on the stud revolve to opposite and symmetry set up in the inboard of die holder.

It is further characterized in that:

scales are marked on the end face of one side of the die holder along the width direction of the U-shaped bottom face of the die holder.

The length of inserting the piece with the length of die holder equals, stud is located the length direction's of inserting the middle part, be equipped with on the bottom surface of inserting two with the rectangle inserted key that stud's length direction is unanimous, two rectangle inserted key symmetry set up in stud's both sides, correspond on the U type bottom surface of die holder the rectangle inserted key is opened respectively along the rectangle keyway that width direction set up, two on inserting the piece rectangle inserted key respectively sliding fit insert corresponding in the rectangle keyway.

And a hand wheel is installed at one end of the stud bolt.

The insert is made of Cr12MoV die steel.

The utility model has the advantages that:

the utility model discloses a high strength plate lower mould of bending, it has set up stud, and stud rotates with the both sides wall of die holder to be connected, two insert respectively screw-thread fit install at stud two sections revolve to opposite screw on to through corotation or reversal stud, two insert can carry out stepless relative motion or stepless phase motion, realize two and insert the infinitely variable control of distance between, and then can bend the high strength plate of arbitrary thickness, it is more convenient to adjust.
