Abstract

The utility model discloses a seal ring processing knife, which belongs to the field of knives. The seal ring processing knife comprises a knife handle (1), and is characterized in that a ring-shaped outer knife (3) and an inner knife (4) are arranged on the knife handle (1), the outer knife (3) and the inner knife (4) share the same axis, and a feeding opening (2) is formed on side edges of the outer knife (3) and the inner knife (4). The seal ring processing knife provided by the utility model has a simple structure, is convenient to operate, and is suitable for small batch seal ring production.

Description

The sealing ring process tool

Technical field

The utility model relates to a kind of cutter, particularly a kind of sealing ring process tool.

Background technology

At present, die sinking tool punch process is generally adopted in the processing of sealing ring, designs the mould of different sizes according to different sealing rings.Mould is divided into drift and die, is adding man-hour, and drift and die are fixed on punch press or the manual pressing equipment, utilizes the shearing force between drift and die that encapsulant is deformed, and motion is cut off encapsulant and formed sealing ring mutually.Sealing ring is generally nonmetallic materials, and its toughness is strong, is easy to generate the limit phenomenon of collapsing in punching course, and friction impact mutually between drift and die is bigger to the wearing and tearing of the drift edge of a knife.Existing method of producing sealing ring can only be processed at a kind of sealing ring of size, when processing capacity is big, its cost is lower, but when processing capacity hour, early stage, production mould need consume a large amount of time and expense, simultaneously processing capacity after a little while, the cost of single-piece sealing ring is quite expensive.The processing sealing ring needs rational bulk and accurate location now, requires workman's technical capability height, and this has also caused the cost height of single-piece sealing ring.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of simple in structure,

Operate simple and easyly, be suitable for sealing ring process tool that the sealing ring of small lot is processed, the sealing ring that sealing circle process tool is processed into, consumptive material is few, and cost is low.

The technical solution adopted in the utility model is as follows:

Sealing ring process tool of the present utility model comprises handle of a knife, and described handle of a knife is provided with the outer cutter and the interior cutter of annular, and described outer cutter and interior cutter spacing are on same axis, and the side of described outer cutter and interior cutter is provided with the feed mouth.

Owing to adopted said structure, outer cutter and interior cutter are annular, and it is on same axis, handle of a knife is installed on the drive unit, when sealing ring is processed, encapsulant is fixed, drive unit drives the cutter rotation then, transfers cutter, and the control cutter is processed encapsulant.Cutter is provided with the feed mouth, the side of cutter and outer cutter in the feed mouth is arranged at, cutter forms a breach with outer cutter in making, thereby the outer cutter outside is communicated with interior cutter is inboard, can be 1 feed mouth as required, also can be 2 feed mouths, can certainly be a plurality of feed mouths, when whole cutter contacts with encapsulant, at first encapsulant is cut, in the process from advancing knife-edge part, the processing scrap can be discharged from the feed mouth, cutter high speed rotating cutting disposablely can process sealing ring, has saved the procedure of processing of sealing ring.After processing several sealing rings, can from the feed mouth with interior cutter and outside sealing ring between the cutter take off, thereby made things convenient for the processing of sealing ring.Sealing ring process tool of the present utility model, simple in structure, easy to operate, disposable sealing ring is machined, reduced manufacturing procedure, reduced waste, saved cost.

Sealing ring process tool of the present utility model, the cutting edge of described outer cutter is outside, and the cutting edge of described interior cutter is inside.

Owing to adopted said structure, outer edge is outside, interior edge is inside, can accurately measure the sealing ring size that needs cutting, make disposable processing can reach requirement, processed encapsulant can be cut easily next, even there are some uncut places, can not damage sealing ring yet, need guarantee the sealing ring integrity partly of processing well.

The described feed mouth of sealing ring process tool of the present utility model is the transition cutting edge of arc with outer cutter, interior cutter junction.

Owing to be set to the transition cutting edge of arc in the junction, the feed mouth can with interior cutter and the transition well of outer cutter, promptly adding man-hour, cutter carries out the transition to cutting edge easily advancing knife-edge part, thereby processing avoids cutter to be impacted simultaneously more easily, makes cutter life longer.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:

1. sealing ring process tool of the present utility model, simple in structure, easy to operate.

2. sealing ring process tool of the present utility model can disposablely be processed sealing ring and put in place, has reduced manufacturing procedure, has reduced waste, has saved cost.

3. sealing ring process tool of the present utility model is fit to the demand that the small lot sealing ring is produced.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to profile.

Mark among the figure: cutter, 5-transition cutting edge in 1-handle of a knife, 2-feed mouth, the outer cutter of 3-, the 4-.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Embodiment 1 as depicted in figs. 1 and 2, sealing ring process tool of the present utility model, comprise handle of a knife 1, handle of a knife 1 is provided with outer cutter 3 and interior cutter 4, outer cutter 3 and interior cutter 4 are annular, and both are positioned on the same axis, satisfy the structure of sealing ring donut, described outer cutter 3 is provided with feed mouth 2 with the side of interior cutter 4, is convenient to chip removal and takes off sealing ring.The cutting edge of outer cutter 3 is outside, and the cutting edge of described interior cutter 4 is inside, can save the sealing ring between outer cutter and the interior cutter effectively from damage, more can accurately measure the size of the sealing ring that needs processing.Described feed mouth 2 is the transition cutting edge 5 of arc with outer cutter 3, interior cutter 4 junctions, makes the cutting edge transition smoothly of feed mouth and cutter, thereby has guaranteed that cutting knife is not hit, and increases its service life.Certainly as required, when less sealing ring is added man-hour, transition cutting edge 5 can be set also can process sealing ring well.Cutter with transition cutting edge 5, be used for the processing of more a bigger size sealing ring, when the sealing ring size needs hour, can not need this transition cutting edge 5, only keep feed mouth 2, the side of cutter 4 and outer cutter 3 in feed mouth 2 is arranged at, cutter 4 forms a breach with outer cutter 3 in making, thereby outer cutter 3 outsides and interior cutter 4 inboards are communicated with.Sealing ring process tool of the present utility model, can be according to the actual needs, be designed to have the cutter of 1 feed mouth 2, also can be designed as the cutter that has 2 feed mouths 2, perhaps as required, have a plurality of feed mouths 2, so that to the processing of sealing ring, convenient processing is as the criterion to encapsulant to satisfy.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
