Trimming die for metal product production

Abstract

The utility model relates to the technical field of metal product production, in particular to a trimming die for metal product production, which comprises a base, and a support plate is mounted at one end of the top of the base. The two movable blocks move relatively outside the two-way threaded rod, so that the two limiting plates are driven to limit and fix the metal workpiece, the threaded rod is driven to rotate through the protruding block, and the trapezoidal block moves outside the threaded rod and extrudes the triangular block at the same time; the triangular blocks compress the reset springs and drive the limiting rods to penetrate through the through holes to extend to the outer portions of the fixing blocks to be synchronously connected into the limiting holes so that the trimming die plate can be fixedly installed between the two fixing blocks. Therefore, the problems that a traditional trimming die for metal product production can only conduct trimming in one shape, and a trimming die plate cannot be rapidly replaced are effectively solved.
