Abstract

The utility model relates to the technical field of zipper production device, in particular to a knife for a zipper tooth pulling device. The knife of the zipper tooth pulling device comprises an upper punch knife and a lower punch knife which are arranged oppositely and is characterized in that a groove extending in the knife edge length direction is formed in the knife edge end face of the upper punch knife, one downward extending triangular stamping block is respectively arranged at two ends of the knife edge, the knife edge end face of the lower punch knife is matched with the groove of the knife edge end face of the upper punch knife, and oblique planes tangent with the stamping blocks are formed on two ends of the knife edge of the lower punch knife. As the description, the contact area of the upper punch knife and the lower punch knife is small, pulling force is large, and the knife edges of the upper punch knife and the lower punch knife are not easily abraded. In addition, a zipper subjected to tooth pulling has few warping teeth and free of remaining teeth, the requirement for a chain blank is reduced, and the reworking rate is reduced.

Description

A kind of cutter for slide fastener exodontia device

Technical field

The utility model relates to slide fastener production equipment technical field, is specifically related to a kind of cutter for slide fastener exodontia device.

Background technology

Existing, slide fastener is bar shaped while making, and after making, length is according to demand removed the chain tooth at bar shaped slide fastener two ends again, traditional except tooth be by manually carrying out, not only inefficiency but also easily leave residual voltage, damage chain band.

For addressing the above problem, application number is: 201210052974.5 disclose a kind of exodontia device for the fixed cun toothwash of metal zip fastener, it is characterized in that: this device comprises upper bolster, die shoe, and its correspondence is arranged on the below of described upper bolster; Upper stamping knife, it is fixed on the bottom of described upper bolster; Counterdie, it is fixed on the top of described die shoe, and setting corresponding to described upper stamping knife; Some positioners, its distribution is arranged on the both sides of described upper bolster; And dynamic link, it is fixed on described upper bolster top.This kind coordinated slide fastener had tooth pulled out with counterdie by upper stamping knife for the exodontia device of the fixed cun toothwash of metal zip fastener, the tangent plane of its upper bolster both sidewalls and upper stamping knife is perpendicular, the two ends of therefore going up stamping knife are right angle, when the exodontia of upper stamping knife and the contact area of slide fastener large, not only going up stamping knife two ends easily weares and teares, and chain tooth easily remains on chain band, especially slide fastener only sticks up tooth, residual tooth in place more, to chain embryo require high.

Utility model content

For overcoming deficiency of the prior art, the utility model provides a kind of cutter for slide fastener exodontia device, realizes tool life, reduces and sticks up tooth, residual voltage, reduces the requirement to chain embryo.

For achieving the above object, the technical solution adopted in the utility model is as follows: plant the cutter for slide fastener exodontia device, comprise stamping knife and lower stamping knife, on this, stamping knife and lower stamping knife are oppositely arranged, it is characterized in that: the edge of a knife end face of described upper stamping knife is formed with groove and an edge of a knife two ends of extending along edge of a knife length direction and is respectively provided with a triangle pressing block to downward-extension, the edge of a knife end face of described lower stamping knife and upper stamping knife edge of a knife end face groove edge of a knife two ends suitable and lower stamping knife form the inclined-plane tangent with pressing block.

Further, the length of pressing block be 0.4-0.8mm, highly for 0.8-1.2mm.

Further, the angle of pressing block is 25-35 °.

Further, upper stamping knife and pressing block are one-body molded.

Further, on upper stamping knife, lower stamping knife, have cutter fixing hole.

From above-mentioned to description of the present utility model, the cutter for slide fastener exodontia device that the utility model provides, on it, the contact area of stamping knife and lower cutter is little, pull out force is large, the edge of a knife of not only going up stamping knife and lower stamping knife is not easy wearing and tearing, and exodontia after slide fastener coupling element stick up tooth few, without residual tooth, the requirement of chain embryo is reduced, reduce rework rate.

Detailed description of the invention

Below by detailed description of the invention, the utility model will be further described.

Shown in Fig. 5, a kind of cutter for slide fastener exodontia device, comprises stamping knife 1 and lower stamping knife 2, and on this, stamping knife 1 is oppositely arranged with lower stamping knife 2;

On upper stamping knife 1, having cutter fixing hole 11, edge of a knife end face is formed with groove 12, an edge of a knife two ends of extending along edge of a knife length direction and is respectively provided with a triangle pressing block 13 to downward-extension; this pressing block 13 is one-body molded with upper stamping knife 1; and the length of pressing block is 0.8-1.2mm, highly for 1.2-1.4mm; angle is 25-35 °, and in the utility model, the length of pressing block is 0.47, is highly 0.8, angle is 30 °;

On lower stamping knife 2, have the edge of a knife end face of cutter fixing hole 21, lower stamping knife and upper stamping knife edge of a knife end face groove is suitable and the edge of a knife two ends of lower stamping knife form and the tangent inclined-plane 22 of pressing block.

Shown in Fig. 5, the above-mentioned cutter for slide fastener exodontia device, when use, upper stamping knife 1 and lower stamping knife 2 are individually fixed on slide fastener exodontia device, slide fastener by fixed cun constantly moves between upper stamping knife 1 and lower stamping knife 2, upper stamping knife 1 is to undershoot milling, removal chain tooth, on this, stamping knife 1 is little with the contact area of lower cutter 2, pull out force is large, the edge of a knife of not only going up stamping knife and lower stamping knife is not easy wearing and tearing, and exodontia after slide fastener coupling element stick up tooth few, without residual tooth, the requirement of chain embryo is reduced, reduce rework rate.

Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should belong to the behavior of invading the utility model protection domain.
