Such suppression process is essential when the head of locking ratchet should have than the little thickness of locking ratchet remainder especially.Required for this reason suppression process advantageously is connected in each punching out operation like this, makes the compacting of head of locking ratchet not carry out when the raw MAT'L punching out goes out yet when the locking ratchet.This has advantage, will not collect, be orientated and the location by each isolated locking ratchet in order to carry out suppression process on the locking ratchet.And advantageously by the first punching out operation punching out isolated and thus in the position of the inner locking ratchet that forms machinable unit of raw MAT'L in the raw MAT'L internal fixation, therefore can directly and need not additional treatments ground and suppress by the punching out operation.
Advantageously and then this suppression process with the locking ratchet as whole in another punching out operation punching out go out, thus, the manufacturing process of locking ratchet finishes.
But because formed the hollow space of locking section thus simultaneously, thus also must punching out in last punching out operation go out the outline of locking section, thus, so the manufacturing process of locking section also finishes.
Advantageously, to go out the raw MAT'L of locking ratchet and locking section be steel band in punching out.
Advantageously, has constant thickness as raw-material steel band.
Advantageously, the locking ratchet has a head, and wherein, locking ratchet and locking section have the thickness corresponding thickness with steel band except this head.
Advantageously, this head has the thickness that reduces with respect to the remainder of locking ratchet.
Advantageously, the thickness of the head of locking ratchet reduces by a suppression process.
Advantageously, the head of locking ratchet can go out from the steel band punching out by means of the first punching out operation.
Advantageously, the head that goes out from the steel band punching out of locking ratchet can be suppressed.
Advantageously, the locking ratchet can go out from the steel band punching out in the second punching out operation of suppression process back.
Advantageously, the locking section can go out in the 3rd punching out operation of the second punching out operation back in punching out.
