Ejectors and Transfer System: Keep a tight grip on parts from start to finish

How parts are transferred:

The transfer grippers grasp the parts as they are ejected to carry them to the next station, position them accurately, open, and return during forming.

4-point or 3-point grippers

4-point grippers are used for most symmetrical parts. For some special jobs, like the three-legged tripods, 3-point grippers may be more suitable.

The opening and closing of the grippers is controlled positively in both directions by a pair of cams.

Opening and closing can be timed individually with a scale on one cam; the other is corrected automatically when adjustments are made.

All moving parts under cover

The entire control system with shafts, cams, cam followers, and springs is housed in a sealed enclosure mounted on the side of the bedframe -- shutting out heat, cooling water, and scale.

Only the two hard-chrome-plated carrier shafts and the rigid grippers operate in the tool area.

That's why the Hotmatic transfer works so reliably in such an stressful environment.

Ejectors for all three stations

All three stations have ejectors with return stroke brakes for controlled insertion of the parts. After each stroke the ejectors push the parts out of the dies into the waiting transfer grippers.

You can equip one, two, or all three dies with an ejector, depending on the operation sequence. Standard equipment includes two ejectors, since the third station will normally be used for piercing.

Stroke length is adjusted at each station with adjusting screws on the ejector lever.

A practical feature is the self-adjusting return stroke brake on each ejector rod to assure controlled entry of the blank into the die. Blanks are centered between punch and ejector pin as they are pushed in, which makes lopsided entry impossible.
