Description

In the proposed machine for rolling circular saws and band saws with a spring-driven hammer, the latter is put into operation and the force of its impact is controlled by a folding hand lever, which in the folded position rests on the pressure head of the hammer, and in the straightened position, it operates flexible cable fist clutch lever, including a hammer in the work.

In FIG. 1 is a front view of the machine; FIG. 2 is a side view of it; FIG. 3-side view of the folding arm; FIG. 4-longitudinal section flock.

In the frame / mounted in bearings, the main shaft 2, rotated from the pulley 3. The shaft 2 by means of a gear and gear couplings 4 and 5 rotates the shafts 6 to 8. A working feed roller 7 is mounted on the shaft, performing the main work at rolling. Above the roller 7 there is a pressure upper roller 9, freely mounted on a finger, rigidly fixed in the eye of the JO holder,

sliding in the guide groove in the head box of the bed (Fig. 4). The lowering and raising of the upper roller 9 is controlled by the handle 7 / and the screw J2. In the tide to the head box, in the cylindrical guide, a spring hammer holder 75 is inserted, carrying a plug-in head J4 and a plug-in tooth 75. In the upper part of the cylindrical guide, there is a pressure head 76 ending with an eye on which the folding manual lever 77 (Fig. 3). The lever 77 is used to turn on the hammer and adjust the strength of the snowcock. For this purpose, the lever is connected by a flexible rod to the translation lever 18, which controls the toothed clutch 5. With the latter, when the lever 17 is straightened, the shaft 8, which by means of the cam disc J9, drives the hammer holder 75, engages the tooth 15. By pressing on the lever 17, the spring 20 is compressed, thereby changing its voltage, which is what regulates the force of the impact of the hammer.

Under the striker 75, a removable plate-anvil 27 was laid on a lead pad 22.

The subject matter of the invention.

A machine for rolling circular and band saws, equipped with a spring driven hammer, different

using a device to turn on the hammer and adjust its impact force sucking from a folding hand lever 17 (Fig. 2-4) connected, when straightened, to the shifting lever 18 of the fist clutch 5 (Fig. 2, 3) and leaning when folded position on the pressure head 76 of the hammer.
