Abstract

The utility model discloses an one -time molding cutter of star sealing washer, including handle of a knife and tool bit, be equipped with the linking arm between tool bit and the end part of the tool holder, the linking arm sets up with the handle of a knife is perpendicular, the tool bit is including front, major flank, minor flank, main cutting edge, front cutting edge and knife tip, nose angle between main cutting edge and the front cutting edge is 30, the knife tip is 8mm to the distance of handle of a knife, the long 2mm of main cutting edge, the long 1.5mm of front cutting edge. The utility model discloses a processing of four terminal surfaces of star sealing washer can be accomplished through purpose -made tool bit to the one -time molding cutter under the circumstances of a clamping, processing is the finished product promptly after accomplishing, need not to pass through any processing again to the size is stable, the convenient control of tolerance grade, has avoided the product defects that the secondary clamping caused.

Description

A kind of disposal molding cutter of star sealing ring

Technical field

This utility model relates to lathe tools technical field, particularly to the disposable one-tenth of a kind of star sealing ring Type cutter.

Background technology

Be four sides structure currently for section form and four faces be not the most plane sealing ring (such as star Shape sealing ring) processing, be usually first mold compression molding, then form product, this life through over cure Production. art batch production many for single variety is feasible, but is as being continually changing of the market demand, many product The production and processing mode planting small lot is the most common, and this just causes the biggest trouble to manufacturing enterprise, needs Open the substantial amounts of mould of system, exchange the most on a production line.

Further, along with the continuous progress of science and technology, the high-quality star sealing ring demand of high accuracy is got more and more, Conventional mould pressing process is then difficulty with.Because rubber has contraction, and different joining in process of production Side's shrinkage factor can be variant, is difficult to allow product through multiple tracks techniques such as mold pressing, sulfurations by previous adjustment After just reach a point-device size.

Furthermore, mould pressing process easily produces bubble, and bubble is inside rubber ring, it is not easy to be found, but throws Enter actually used after sealing effectiveness but differential pressure the biggest.If employing turnery processing, the four sides of star sealing ring Being required for processing, wherein three faces can be processed and formed at one time by existing turning cutting tool, and another side structure can only By reprocessing after secondary clamping, but because quality of rubber materials is softer, secondary clamping is difficult to.

Utility model content

For solving above-mentioned technical problem, the utility model discloses the disposal molding cutter of a kind of star sealing ring Tool, including handle of a knife and cutter head, is provided with linking arm between described cutter head and handle of a knife end, described linking arm with Handle of a knife is vertically arranged, before described cutter head includes, major flank, minor flank, main cutting edge, front cutting edge with And point of a knife, the nose angle between described main cutting edge and front cutting edge is 30 °, described point of a knife to handle of a knife away from From for 8mm, the long 2mm of described main cutting edge, the long 1.5mm of described front cutting edge.

The beneficial effects of the utility model are:

Disposal molding cutter of the present utility model is by special cutter head, it is possible in the case of clamped one time Complete the processing of four end faces of star sealing ring, be i.e. finished product after machining, it is not necessary to again through any process, And dimensionally stable, tolerance grade are convenient to be controlled, it is to avoid the product defects that secondary clamping is caused.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.

As it is shown in figure 1, the disposal molding cutter of a kind of star sealing ring, including handle of a knife 1 and cutter head 2, Being provided with linking arm 3 between cutter head 2 and handle of a knife 1 end, linking arm 3 is vertically arranged with handle of a knife 1.

Cutter head 2 includes above 21, major flank 22, minor flank 23, main cutting edge 24, front cutting edge 25 with And point of a knife 26.Nose angle α between main cutting edge 24 and front cutting edge 25 is 30 °, point of a knife 26 to cutter Distance d of handle 1 is 8mm, the long 2mm of main cutting edge 24, the long 1.5mm of front cutting edge 25.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.

Claims

1. a disposal molding cutter for star sealing ring, including handle of a knife and cutter head, it is characterised in that Being provided with linking arm between described cutter head and handle of a knife end, described linking arm is vertically arranged with handle of a knife, described cutter head Before including, major flank, minor flank, main cutting edge, front cutting edge and point of a knife, described main cutting edge and Nose angle between front cutting edge is 30 °, and the distance of described point of a knife to handle of a knife is 8mm, described main cutting edge Long 2mm, the long 1.5mm of described front cutting edge.
