Behind the first step die cast, the workpiece that punching press is good is broken off with the fingers and thumb down and is used for next step processing.
The shortcoming of this step is to get the workpiece direction easily wrong, and the easy seam broken of corner angle.
The second step unipods dashes, and puts hold-down ring into mould, carries out front, reverse side punching press.Shortcoming is that hold-down ring is uneven above the edge of a knife, and neither security effectiveness is low again for the easy progressive die frame of hand.And guiding is few, and reverse side dashes and is not easy to get into the punch die edge of a knife, and is positive towards easy seam broken unfilled corner
The 3rd step mill grinds off and dashes processing incompleteness afterwards, and shortcoming is to only depend on the roundness of rounded face hand-manipulated to be difficult to control.
The 4th step was bored macropore, the 5th step brill aperture:
Workpiece is placed on the anchor clamps boring.Shortcoming is to produce in batches to only depend on centre bore, and during boring, hole centre distance is not easy control.
The 6th step chamfering: need carry out chamfering twice to tow sides, owing to the reason of processing causes the not of uniform size of chamfering easily.
The 7th step tapping: the shortcoming of conventional process flow is, since the big or small quality control reason in above-mentioned hole, the sliding tooth of tapping processing ease.
In sum, prior art exists manufacturing procedure many, and product quality shortcoming more rambunctious causes the high problem of production cost, and long processing time, therefore needs to improve.
Summary of the invention
In order to solve the problem that exists in the prior art, the invention provides a kind of minimizing operation, improve the processing mold and the processing method of the cable hold-down ring of product quality.
The present invention at first provides a kind of improved hold-down ring processing method:
The charging aperture of compression mod, slag-drip opening changed into by the two outer radius places of original workpiece be located at side plane place, both sides; And adopt core to fetching two holes on the die casting hold-down ring;
Use squeezing tapping to come the screw thread on the shaping workpiece hole;
When the squeezing tapping operation, use No. 20 machine oil that add 5% automobile JB additive as lubricating fluid; Or use engine oil as lubricating fluid.
Through adding the surface finish treatment procedures after the above two procedures processing.
The present invention also provides a kind of dashing to put device, comprises mould, and said mould comprises stub bar, material handle;
Said charging aperture is located at the side surface of workpiece of required processing, and said slag notch is located at the workpiece another side of required processing.
Said material handle number is more than or equal to 2;
Said material handle is liftable and laterally mobile;
Said material handle has at least four working grooves that hold workpiece to be processed;
Hole on the said workpiece adopts core to fetching casting forming;
Usefulness of the present invention is, uses above-mentioned processing method to compare with former method, has practiced thrift operation, and shorten process time, reduced carbon emission, and efficient improves, product appearance high conformity, and product quality improves.
