Description

Special cutter for machining dust cover

Technical Field

The utility model relates to an equipment is used in dust cover processing specifically is a special cutter of dust cover processing.

Background

Dust covers can be used to protect items from external corrosion and damage. Currently, the requirement for the circular size of dust cover products is high, and the local thickness of the dust cover products is usually required to be controlled within 0.3 mm. The existing cutting method is difficult to meet the precision requirement, and the precision requirement is mainly caused by the difference of cutter precision, so that the part with thinner thickness in the product is easy to deform, and the product dimension is poor.

Disclosure of Invention

An object of the utility model is to provide a special cutter of dust cover processing to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a special cutter of dust cover processing, its includes base and scraping wings, base and scraping wings are connected through a plurality of fixed pins, and the scraping wings can be followed the fixed pin removes, still the cover is equipped with the spring on the fixed pin, the spring is located between base and the scraping wings, the base is still fixed and is equipped with the cutting die, the cutting die is located between base and the scraping wings, be equipped with on the scraping wings and supply at least the first through-hole that the edge of a knife portion of cutting die passes through.

Furthermore, the base and the material pushing plate are rectangular, and four corners of the base and four corners of the material pushing plate are connected through at least one fixing pin respectively.

Further, the cutting die is a circular cutting die.

Furthermore, the surface of the cutting die facing the material pushing plate is convexly provided with an annular cutting edge part.

Furthermore, the spring is movably sleeved on the fixed pin.

Furthermore, when no external force is applied to the base and the material pushing plate, two ends of the spring respectively support and push the base and the material pushing plate.

Further, the first through hole is formed in the center of the material pushing plate.

Furthermore, a second through hole is formed in the base and communicated with the first through hole, so that a continuous channel is formed in the cutter.

Further, the edge part of the cutting die is distributed in the continuous channel.

Compared with the prior art, the beneficial effects of the utility model are that: when the dust cover is machined, the part with the thickness of less than 0.3mm can be prevented from deforming, particularly, the machining precision can be controlled within 0.02mm by matching with laser cutting machining, the integral cutting of a product can be completed simultaneously, the deformation is further avoided, and the method can be applied to the plane cutting process of other thin-wall (with the thickness of less than 1 mm) blow-molded products.

Fig. 2 is a schematic perspective view of a special tool for machining a dust cover in the embodiment.

In the figure: 1. a base; 2. cutting the die; 3. a material pushing plate; 4. a spring; 5. and fixing the pin.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, a special tool for machining a dust cover includes a base 1, a cutting die 2, a material pushing plate 3, four fixing pins 5, a spring 4, and the like.

Further, the base is connected with the material pushing plate through a plurality of fixing pins, the material pushing plate can be moved along the fixing pins, springs are further sleeved on the fixing pins and located between the base and the material pushing plate, a cutting die is further fixedly arranged on the base and located between the base and the material pushing plate, and first through holes at least allowing the edge of the cutting die to pass through are formed in the material pushing plate.

Further, the cutting die is a circular cutting die.

Furthermore, the spring is movably sleeved on the fixed pin.

This special cutter of dust cover processing when using, when the scraping wings atress gos forward, the spring on the fixed pin is compressed, make the cutting die on the base contact the dust cover and carry out die-cut, the cutting die retreats after die-cut completion, the spring kick-backs when the cutting die retreats, make in the cutting die shrink back the scraping wings, the spring promotion of simultaneously being kick-backed at the scraping wings, make the scraping wings on the surperficial stub bar and the cutting die after the cutting break away from, and then make the stub bar drop from the cutting die is automatic, thereby production efficiency has been improved by a wide margin.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
