Description

A kind of device for shearing I-shaped structure of zipper

Technical field

The present invention relates to a kind of I-shaped structure of zipper process equipment, especially a kind of device for shearing I-shaped structure of zipper.

Background technology

In metal zip fastener is made, stop part under the metal on the metal zip fastener, its cross section is " worker " font, so be called the I-shaped sign indicating number; The I-shaped sign indicating number is before being clamped to the fastener stringer end, and its cross section is the metalwork that is " X " alphabetical shape, and these hardwares are to cut down one by one from the metal wire rod of cross section one-tenth " X " shape.At present, be mostly to adopt instrument manual operationss such as high speed saw blade or grinding wheel from metal wire rod, to cut I-shaped sign indicating number to be installed down one by one, but this manual mode of shearing metalwork, time-consuming take a lot of work and also labour intensity big, efficient is low, produces metal fragment, waste material in the cutting process simultaneously.

Summary of the invention

The object of the present invention is to provide a kind of production efficiency height, the no broken device for shearing I-shaped structure of zipper of cutting of processing.

For achieving the above object, the technical solution adopted in the present invention is:

A kind of device for shearing I-shaped structure of zipper, comprise support, on the work top of support, be provided with punch die, fixed die that matches with punch die and wire agency, before described punch die comprises, after, a left side, right clamp drift and with preceding, after, a left side, before the right clamping drift difference correspondence, after, a left side, right rail, before, after, a left side, the shape of right clamping drift is corresponding with the wire casing of metal wire rod, before, after, a left side, before right clamping drift is installed in respectively, after, a left side, in the right rail, before, a left side, the right drift that clamps is connected with the clamping power set by slide block, in chute, be equipped with the drift back-moving spring, clamp drift about described and also be provided with horizontal concrete chute and the back-moving spring in horizontal concrete chute, the both sides of front clamp drift be provided with clamped condition can with about clamp the projection that drift contacts, described fixed die is fixed on above the punch die, in the middle of fixed die, have the through wires hole that adapts with the metal wire rod cross section, before this through wires hole faces, after, a left side, the right drift that clamps clamps the clamping slot that forms.

Preferably, described clamping power set are cam, and the rotating shaft of this cam is connected with power source.

Preferably, described wire agency comprises line sending fixed mount and the line wheel that is installed on the fixed mount, also is provided with Wire Wheel in the bottom of line sending fixed mount.

Further preferred, described Wire Wheel has two groups, and they are installed on the same vertical curve.

Preferably, described Wire Wheel is driven by stepper motor.

After the present invention adopts said structure, have following beneficial effect:

At first, by the fixed die that punch die is set and is complementary with punch die, and punch die comprises that front, rear, left and right clamp drift and clamp the corresponding respectively front, rear, left and right chute of drift with front, rear, left and right; The shape of front, rear, left and right clamping drift is corresponding with the wire casing of metal wire rod; Front, rear, left and right clamp drift and are installed in respectively in the chute of front, rear, left and right, and preceding, left and right clamping drift is connected with the clamping power set by slide block, is equipped with the drift back-moving spring in chute; Clamp drift about described and also be provided with horizontal concrete chute and the back-moving spring in horizontal concrete chute, the both sides of front clamp drift be provided with clamped condition can with about clamp the projection that drift contacts; Described fixed die is fixed on above the punch die, has the through wires hole that adapts with the metal wire rod cross section in the middle of fixed die, and this through wires hole faces front, rear, left and right and clamps the clamping slot that drift clamps formation; When metal wire rod reaches punch die, start and clamp power set, before, left and right clamping drift simultaneously to metal wire rod near and with its clamping, the front clamp drift moves on, the projection on its both sides promotes left and right clamping drift simultaneously along horizontal concrete chute fast moving backward together, under punch die and fixed die relativity, metal wire rod is cut off, realize the shearing of I-shaped sign indicating number metalwork, remove the chucking power that clamps power set, under the effect of drift back-moving spring, preceding, left and right clamping drift unclamps and resets, metalwork falls, and no metal fragment produces.Repeat above-mentioned operation, Automatic Control, thus the production efficiency height,

Secondly, clamp power set and adopt cam, cam has guaranteed to clamp the position that drift advances to push away at every turn, and it is too tight or too loose can not occur clamping metal wire rod.

Once more, wire agency comprises line sending fixed mount and the line wheel that is installed on the fixed mount, also is provided with Wire Wheel in the bottom of line sending fixed mount, and Wire Wheel is driven by stepper motor; Therefore, realize automatic interval to the punch die line sending,
