(54J MACHINE FOR EXPANDING THE ROLLERS

CHAINS

working bodies of the machine at the time of flaring.

The machine contains a ROTOR 2 mounted on frame 1 with a drive central shaft 3. In the rotor, a flaring mechanism is mounted in the form of spindle spindle heads evenly spaced around the circumference; The upper spindles 4 are connected to the sliders 6 in contact with the cams 7, ensuring the reciprocating movement of the spindles m.

The fixation mechanism is made in the form of an 8 star gear unit freely mounted on the shaft .3 of the rotor to accommodate the chain to be processed on it, which is fixed in the working shaft of the subplug: sliders 9 slide along the copiers 10. 12, which on the outer side presses against the sprocket of the block with flexible member 13, for example in the form of a chain with stops covering the rotor and moving synchronously with the block of sprockets.

The block of 8 stars is kinematically connected with the intermittent-sweep mechanism 14, which contains a weduction of a prostatic cam 15 fixed on the shaft 16. The Slave Link 17 with the rollers 18 is not connected kinematically with an asterisk 22 and through flexible drive 23 with a block. 8 stars.

The machine works as follows.

When the main drive rotates (not shown), the rotor starts to vrajat, the sliders 6 overlap the protrusions of the cam 7 and the rotating spindles 4 and 5 f are working down. at the same time, the slide blocks 9 are located in the conic holes of the block of 8 starters, the centerpiece of that saG.ch machining-roller rollers 12 coaxially with the upper 4 and lower 5 Spindle. The flexible element 13, moving synchronously with the chain 11 to be machined, constantly presses the chain to the depressions of the star-block 8 on the processing section. The tool of the stp1 of the items, having come into contact with the roller and, rotating and moving down, rolls the rollers to form a head.

 After the formation of the heads, the chains 4 and 5 were quickly retracted and the slide blocks 9 were drawn from the conical holes of the sprocket unit, released from its fixation. At this time, the roller 18 extends into the accelerated movement section of the cam 15. The accelerated movement is transmitted through the vendome link 17, gears 19, 2U, 21, sprocket 22 and hard drive 23 to the rotor sprocket unit. There is an accelerated movement of the block of stars by one step of the chain being processed. The cycle is repeated.

Thus, during one revolution of the rotor, the spindles 4 and 5 enter into operation, and the block of 8 sprockets turns one step of the chain as many times as the chain steps spill between adjacent spindles.

Such a machine design of the chain roll expansion allows a significant increase in chain processing performance, which depends only on the time of formation of the head on the roller and practically does not depend on the time of its movement, while both of these parameters affect the performance.
