The automaton is equipped with a system 61 recording and showing forces arising in the process of stretching the chains, as well as switching off the automaton in the absence of a load (at the end of the chain), breaking the chain and exceeding a predetermined load.

The machine works as follows. at once.

From the driving motor 2 through the V-belt transmission 3, the flywheel 4 and the firing clutch, rotation is transmitted to the drive shaft 5 and further from gear 6 through the gear drive 7 to the shaft 8. Through the faceplate 9 mounted on the shaft 8, through pu 10 . the movement of the levers 11 and 13 with the pusher 14. From the eccentric mechanism located on the shaft 8, through the connecting rod 15 is rocking motion of the double-shouldered lever 16, which through the axis 18 reports the reciprocating movement of the swiveling crest 19. From the fist 23 mounted on the shaft 8, through the roller 24, the lever 25, the t gu 26 the lever 26 a is driven by the slide 27.

Before starting the operation, the chain 62 through the supporting roller 57 along the guides 33 between the grip 32, the pressing bars 40 and 41, between the grip 31, the pressing bars 50 and 51 is fed to the working area of the machine and clamped by the locking mechanism 55.

After switching on the machine, the swiveling carriages 19 and 20 from the slide 27 are lifted and the chain 62 is placed in the nests of the grippers 31 and 32. The carriage 20 with the gripper 32 is non-moving at the time of chain extension, and the carriage 19 with the gripping 31 moves from the eccentric mechanism, the connecting rod 15 and two-arm lever 16 to the extreme right position. Thus, chain 62 stretches, i.e. load calibration or test circuit

For automatic drawing

chains 62, after each stretching of the predirection chain 62, the grips 31 and 32 in front of it are assigned a lever 13 with a pusher 14, which, having made a swinging movement from the leftmost position to i i right most, moves the chain 62 along the guides 33 and 34. a 14 aa horizontal pusher is gripped by a link on the southwatch; cabbage 34,

In order to obtain a given size of the section of the chain subjected to stretching, the rotary carriage 20 with the slide 21 is set to the desired position with the help of screws 22, which can be rotated more with the help of the handwheel 63.

At the end of the stretch, the chains of the carriage 19 and 20 together with the grippers 31 and 32 of the slide 27 are lowered and the chain is released. At this moment, the mecha lever30

stretching with a slight displacement of links with a working profile of grippers.

The proposed design of an automatic shutdown of an automaton contributes to an increase in the reliability of its operation and productivity.
