Zusammenfassung:Device for restoring the characteristics of cylindrical spiral springs, in which the fastening elements are made in the form of fixed and mobile holders with fastening washers with open grooves toward their center, fixed holder is rigidly connected with the right end of the open framework, and mobile holder with the loading rod is mounted with possibility of axial displacement, and the axes of the mobile and fixed holders are coaxial, and spiral element is mounted on this axis from the left side in the loading rod, left end of which is made in the form of spline shaft, which is in interaction with the spindle drum and vernier through the spline connection, the drum is mounted on the bed, where two vertical plates with coaxial radius grooves are rigidly mounted in parallel between them from two sides along its length, in said grooves are mounted with possibility of free displacement four fastening bolts, opposite ends of which are rigidly connected with the open framework with possibility of mutual displacement on the radius grooves, the bath with solution for hardening is mounted under open framework on the bed, and the dimensions of the bath are greater than the dimensions of the open framework at their mutual displacement, and the length of radius grooves ensures complete sinking of the open framework into the solution in the bath, right fastening bolts are rigidly connected with the lever with possibility of free displacement on the radius grooves, and lever can be rigidly fixed with the help of the ratched coupling.
