Abstract

The utility model discloses the two draw cut cuttves in a kind of side's tooth row microphone machine, the large edge of a knife of an indent is only provided with on the tool rest of this cutting knife, the large edge of a knife of an indent is only provided with on the tool rest of this cutting knife, a little edge of a knife is convexly equipped with in this large edge of a knife bottom surface is integrally formed, the described little edge of a knife is a curved surface projection, and is arranged on the centre position of large edge of a knife bottom surface.The utility model, based on the two theory of engagement that zips of square tooth row microphone machine operation principle and metal, merges into an edge of a knife two edges of a knife that two for prior art draw cut cutter is provided separately up and down on same position, use principle and work flow constant.By simplifying cutter structure, not only save the material cost of cutting knife, and working (machining) efficiency is higher.Chamfering and cutting two operations are merged on an edge of a knife by the utility model, complete two actions simultaneously, not only extend the service life of cutting knife, and reduce product defects further, significantly Improving The Quality of Products.

Description

Two draw cut cuttves in a kind of side's tooth row microphone machine

Technical field

The structure that the utility model relates to a kind of slide fastener production equipment cutting knife is improved, and the structure of the two draw cut cuttves particularly tooth row microphone machine in the side's of relating to used is improved.

Background technology

Two draw cut cuttves above existing market in tooth row microphone machine can see Chinese patent literature CN200620125405.9 " slide fastener production resin row microphone machine Cutter apron device " disclosed in the 2007.10.31.With 2014.09.10 disclosed in CN201420194402.5 " row microphone machine changeable type cutting knife ".Utilize existing pair of draw cut rail to process, operation Jiu You tri-road, comprise line cut twice, electrode once.Substantially as shown in Figure 1, 2, the tool rest in cutting knife is provided with two edges of a knife 10,20 one on the other to the structure of two draw cut cutter, two edges of a knife 10,20 small one and large one.The effect of the little edge of a knife 20 of below carries out chamfering (two difference of drawing product and mill run) to copper cash, and the large edge of a knife 10 of top cuts again, carries out outside shaping to copper cash.One on the other, difficulty of processing is large, and the little edge of a knife 20 easily bursts apart by stress for cause two edges of a knife 10,20, and when square tooth row microphone machine is produced, product easily produces burr, unstable product quality.And the accessory structure causing other to coordinate with it is also complicated.

Utility model content

For prior art Problems existing, the utility model provides the two draw cut cuttves in a kind of side's tooth row microphone machine.Two draw cut cuttves after improvement, not only structure is simple, and has simplified manufacturing procedure, and during production, product quality is more stable, the longer service life of cutting knife.

For achieving the above object, technical solutions of the utility model are:

Two draw cut cuttves in side's tooth row microphone machine, are only provided with the large edge of a knife of an indent on the tool rest of this cutting knife, are only provided with the large edge of a knife of an indent on the tool rest of this cutting knife, are convexly equipped with a little edge of a knife in this large edge of a knife bottom surface is integrally formed.

Two draw cut cuttves in foregoing a kind of side's tooth row microphone machine, the described little edge of a knife is a curved surface projection, and is arranged on the centre position of large edge of a knife bottom surface.

The usefulness of technique scheme is:

The utility model, based on the two theory of engagement that zips of square tooth row microphone machine operation principle and metal, merges into an edge of a knife two edges of a knife that two for prior art draw cut cutter is provided separately up and down on same position, use principle and work flow constant.By simplifying cutter structure, not only save the material cost of cutting knife, and working (machining) efficiency is higher.Chamfering and cutting two operations are merged on an edge of a knife by the utility model, the little edge of a knife of a convex surface projection shape is established at large edge of a knife convex, complete two actions simultaneously, not only there is no the place that stress is concentrated, not easily burst apart, extend the service life of cutting knife, and reduce product defects further, significantly Improving The Quality of Products.

Accompanying drawing explanation

Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:

Fig. 1 is the perspective view of the two draw cut cutter of prior art;

Fig. 2 is the main TV structure schematic diagram of the two draw cut cutter of prior art;

Fig. 3 is the perspective view of the two draw cut cutter of the utility model;

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

Two draw cut cuttves in a kind of side's tooth row microphone machine as shown in Figure 3, two edges of a knife that have been provided separately up and down of two for prior art draw cut cutter are merged into an edge of a knife by it on same position.The copper cash that the utility model cutting knife cuts out as shown in Figure 6.

Shown in Fig. 4,5, the utility model cutting knife is only provided with the large edge of a knife 20 of an indent on tool rest 10, and the bottom surface in this large edge of a knife 20 is integrally formed is convexly equipped with a little edge of a knife 30.Be a curved surface projection at this little edge of a knife 30, be arranged on the centre position of the large edge of a knife 20 bottom surface, to utilize the B portion of curved surface to copper cash in Fig. 6 to carry out chamfering, the large edge of a knife 20 pairs of copper cash carry out last cutting.

The utility model, by integrally formed for the little edge of a knife 30 inside at the large edge of a knife 20, is exactly that chamfering and cutting two operations are merged on an edge of a knife, completes two actions simultaneously.Not only cutting knife cost reduces, and working (machining) efficiency is higher, and the place not having stress to concentrate, and extends the service life of cutting knife, significantly Improving The Quality of Products.

Above-mentioned explanation illustrate and describes preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
