The specific embodiment
The invention discloses a kind of mouth of pipe deburring cutter head, to improve labourer's manipulation strength, improve the operating efficiency of pipe fitting mouth of pipe deburring operation, and the service life of improving edger.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-Fig. 7, the mouth of pipe deburring cutter head that the embodiment of the present invention provides, carries out deburring operation for treating the mouth of pipe of processing pipe fitting, and its core inventive point is, the blade of this mouth of pipe deburring cutter head has fairshaped curved surface.
Compare with the plane blade that edger in prior art adopts, the mouth of pipe deburring cutter head that the embodiment of the present invention provides, by solid modelling complete design, by simulating sports, analyze and finite element analysis, the structure of line up deburring cutter head is optimized, at its knife edge part, adopt streamlined curved design, so, in deburring operation, can reduce cutting resistance, thereby improved labourer's manipulation strength, improve the operating efficiency of mouth of pipe deburring operation, and the service life of improving edger.On the other hand, anterior angle and relief angle while reducing mouth of pipe deburring cutter head deburring operation, make transition face milder, improves the quality of deburring.
As shown in Figure 1-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 three streamlined curved surfaces in 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, extended service life.Certainly, the blade of mouth of pipe deburring cutter head its form is specifically set not is unique, can also process according to actual needs the situation of pipe fitting, suitably adjust, adopt more multistage streamlined curved surface or other camber line forms, principle is identical, does not repeat them here.
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.By increasing the area of section of cutter head, to strengthen the ability to bear of its transverse load, and can realize jointing, realization is reused.
In order further to optimize above-mentioned technical scheme, the mouth of pipe deburring cutter head that the embodiment of the present invention provides, the angle of its point of a knife and cutting edge frequency of utilization are normal distribution, by the optimization to nose angle degree, can increase the abrasion resistance properties of cutter head.
The mouth of pipe deburring cutter head that the embodiment of the present invention provides, according to the first roughing molded integral of drawing outward appearance, rear fine finishining realizes the basil, after through processing, final smoothing is realized processing.
What conventionally need deburring operation is 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 make can be specially and adopt M42 high speed steel, strengthens the hardness of cutter head, extends 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 make, can be applicable to the deburring operation of all kinds parts widely.
Refer to Fig. 8, the embodiment of the present invention also provides a kind of mouth of pipe edger, comprises cutter head 1, handle of a knife 3, and cutter head 1 is arranged on to the jockey on handle of a knife 3, realized removably connecting of cutter head 1 and handle of a knife 3, so that change according to actual needs corresponding cutter head 1 or handle of a knife 3; Its core inventive point is, 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.
As shown in Fig. 9-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 coordinating with the spherical head of screw 2, offers for the installing hole of cutter head 1 is installed by screw 2 on handle of a knife 3, and the structure of handle of a knife 3 is as shown in Figure 13-Figure 16.Screw 2 is arranged in the screwed hole on cutter head 1 by its external screw thread, its spherical head is withstood the arc groove of cutter head 1 afterbody, to realize fixing to cutter head 1, simultaneously 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, just can, in deburring operation, adjust angle constantly, the mouth of pipe of better laminating pipe fitting to be processed, have better cutting effect, transition face is milder, improves the quality of deburring.
Concrete, the concrete quantity of the installing hole coordinating with screw 2 on 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, that adjusts installing hole offers position and quantity, does not repeat them here.
In sum, the mouth of pipe edger that the embodiment of the present invention provides, adopts M42 high speed steel, by solid modelling complete design, by simulating sports, analyze and finite element analysis, improve the structure of edger and optimize the tool cutting edge angle of blade, attached drift angle, nose angle etc.; The cutting edge of cutter and processed pipe bore, to there is skew, add the special construction design of handle of a knife, in the time of can realizing the automatic reparation of cutter tool cutting edge angle, attached drift angle in operation process, improve working (machining) efficiency and reduce profit mouthful wearing and tearing.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stresses is the difference with other embodiment, between each embodiment identical similar part mutually referring to.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the present invention.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
