The invention relates to metalworking and can be used in hacksaw cutting machines.

The purpose of the invention is to improve the cutting accuracy by increasing the rigidity of the hacksaw blade.

FIG. 1 shows a saw frame of a cutting hacksaw, general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - bar with the shank of the rolling device; in fig. 5 - the same, left view; in fig. 6- clamping pad of the rolling device; in fig. 7 - bar stationary device; in fig. 8 - clamping pad fixed device; in fig. 9 - articulation of the stabilizer and the hacksaw blade; in fig. 10 - the same; right side view; in fig. 11 - stabilizer; in fig. 12 shows the section EE of FIG. eleven; in fig. 13 - hacksaw blade; in fig. 14 - the same, right view.

The tensioning device for fixing and tensioning the hacksaw blade 1 in the saw frame 2 comprises a movable device 3 comprising a bar 4 with a tension shank 5 and a nut 6, a pressure pad 7, an axis 8 and bolts 9 with nuts (not shown), as well as contains a fixed device 10, including the strap 11, the pressure pad 12, the axis 8, the bolts 9 with nuts (not shown).

The bar 4 and the bar 11 have a head 13 with a stabilizing groove 14 and a slope A-A

FIG. 2

a new threaded hole in which the screw 15 is screwed.

In addition, the tensioning device has a stabilizer 16, made in the form of a plate, the ends of which are rigidly fixed in the movable device 3 and the fixed device 10, having reverse bevels 17 evenly spaced on the projections, alternately alternating on the projections 18 bevels and grooves 19, as well as inclined protrusions 20.

For articulating the stabilizer 16 with the hacksaw blade 1, the latter has uniformly alternating back bevels 21 and reverse bevels 17 and 18 and backward bevels 22.

 The saw frame of the cutting hacksaw works as follows.

In the movable device 3 and in the fixed device 10, the stabilizer 16 is inserted into the slots 14 with simultaneous installation

0 of the hacksaw blade 1 so that the back bevels 17 of the stabilizer 16 coincide with the bevels 21 of the hacksaw blade 1, and the bevels 18 of the stabilizer 16 coincide with the reverse bevels 22 of the hacksaw blade 1, then with the help of a nut 6

the saw blade 1 is tightened, and then with the help of screws 15 it is tensioned and the stabilizer 16 is pressed against the saw blade 1 at the same time. The final tension is carried out alternately by a nut 6 and screws 15, followed by fixing with bolts 9 with nuts (not shown).
