The specific embodiment
The invention discloses a kind of mouth of pipe deburring cutter head,, improve the operating efficiency of pipe fitting mouth of pipe deburring operation to improve labourer's manipulation strength, and the service life of improving edger.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also Fig. 1-Fig. 7, the mouth of pipe deburring cutter head that the embodiment of the invention provides is used to treat the mouth of pipe of processing pipe fitting and carries out the deburring operation, and its core inventive point is that the blade of this mouth of pipe deburring cutter head has fairshaped curved surface.
Compare with the plane blade that edger in the prior art adopts, the mouth of pipe deburring cutter head that the embodiment of the invention provides is accomplished design through solid modelling; Through simulating sports analysis and finite element analysis; The structure of line up deburring cutter head is optimized, and adopts streamlined curved design at its knife edge part, so; In the deburring operation, can reduce cutting resistance; Thereby improved labourer's manipulation strength, improved the operating efficiency of mouth of pipe deburring operation, and improved the service life of edger.On the other hand, anterior angle and relief angle when reducing mouth of pipe deburring cutter head deburring operation make transition face milder, improve the quality of deburring.
Like Fig. 1-shown in Figure 3, the blade surface of mouth of pipe deburring cutter head is divided into three sections along its length, has corresponding folding face; Form the streamlined curved surface in three rank; The blade of mouth of pipe deburring cutter head is better matched with the mouth of pipe of pipe fitting to be processed, further reduced cutting resistance, prolonged service life.Certainly, the blade of mouth of pipe deburring cutter head its form specifically is set not is unique, can also process the situation of pipe fitting according to actual needs, suitably adjust, adopt more multistage streamlined curved surface or other camber line forms, principle is identical, repeats no more at this.
As preferably, mouth of pipe deburring cutter head has two knife faces that are oppositely arranged, and the blade transition of two knife faces forms the point of a knife of V-shape.Through increasing the area of section of cutter head, strengthen the ability to bear of its transverse load, and can realize jointing, realize reusing.
For the above-mentioned technical scheme of further optimization, the mouth of pipe deburring cutter head that the embodiment of the invention provides, the angle of its point of a knife and cutting edge frequency of utilization are normal distribution, through the optimization to the nose angle degree, can increase the abrasion resistance properties of cutter head.
The mouth of pipe deburring cutter head that the embodiment of the invention provides, according to drawing elder generation roughing molded integral outward appearance, back fine finishining realizes the basil, after through handling, final smoothing is realized processing.
What need the deburring operation usually is the round mouth copper pipe, corresponding, and the mouth of pipe deburring cutter head of mouth of pipe deburring cutter head for adopting high-speed steel to process can be specially and adopt the M42 high speed steel, and the hardness of reinforcement cutter head prolongs its service life.Certainly, can also be according to the concrete condition of pipe fitting to be processed, the mouth of pipe deburring cutter head that adopts other materials to process can be applicable to the deburring operation of all kinds parts widely.
See also Fig. 8; The embodiment of the invention also provides a kind of mouth of pipe edger, comprises cutter head 1, handle of a knife 3, and cutter head 1 is installed in the jockey on the handle of a knife 3; Realized removably connecting of cutter head 1 and handle of a knife 3, so that change corresponding cutter head 1 or handle of a knife 3 according to actual needs; Its core inventive point is that cutter head 1 is above-mentioned mouth of pipe deburring cutter head, can improve labourer and operate slightly, improves the operating efficiency of copper pipe mouth of pipe deburring operation, and the service life of improving edger.
Like Fig. 9-shown in Figure 12; Jockey is specially the screw 2 that head has spherical structure; The afterbody of cutter head 1 is equipped with the arc groove that cooperates with the spherical head of screw 2, offers the installing hole that is used for installing through screw 2 cutter head 1 on the handle of a knife 3, the structure of handle of a knife 3 such as Figure 13-and shown in Figure 16.Screw 2 is installed in the screwed hole on the cutter head 1 through its external screw thread, and its spherical head is withstood the arc groove of cutter head 1 afterbody, to realize fixing cutter head 1; Because the spherical head of screw 2 and the arc groove of cutter head 1 afterbody match, cutter head 1 can rotate within the specific limits, so simultaneously; Just can in the deburring operation, constantly adjust angle, the mouth of pipe of the pipe fitting to be processed of better fitting; Have better cutting effect, transition face is milder, improves the quality of deburring.
Concrete, the concrete quantity of the installing hole that cooperates with screw 2 on the handle of a knife 3 is two that are oppositely arranged, two screws 2 clamp cutter head 1 from both sides, strengthened the stability of device.Certainly, can be as the case may be, the adjustment installing hole offer position and quantity, repeat no more at this.
In sum; The mouth of pipe edger that the embodiment of the invention provides adopts the M42 high speed steel, accomplishes design through solid modelling; Through simulating sports analysis and finite element analysis, the structure of improving edger with the tool cutting edge angle of optimizing blade, attach drift angle, nose angle etc.; The cutting edge of cutter and processed pipe bore add the special construction design of handle of a knife to there being skew, can realize cutter in operation process tool cutting edge angle, when attaching the automatic reparation of drift angle, improve working (machining) efficiency and reduce profit mouthful wearing and tearing.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
