Specific implementation mode

The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that herein Described specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It further needs exist for It is bright, it illustrates only for ease of description, in attached drawing and the relevant part of the utility model rather than entire infrastructure.

It is that electrode provided by the utility model repairs a die the perspective view of knife as shown in Figure 1, from figure 1 it appears that electrode is repaiied Mould knife include fixes sleeve 2 and with 2 integrally formed three blades 1 of fixes sleeve, fixes sleeve 2 for electrode repair a die knife use When fixation to the knife that repairs a die, three blades 1 are distributed along the radial direction of fixes sleeve 2 in homogeneous radiation shape, and towards in fixes sleeve 2 One end of mandrel is connected with each other, and one end far from 2 central shaft of fixes sleeve is connected to the inner wall of fixes sleeve 2.

Each blade 1 is both provided with the first top surface 11, the first inclined-plane 12 and second close to the part of 2 central shaft of fixes sleeve Inclined-plane 13, wherein the first top surface 11 is arc surface, three the first top surfaces 11 are arranged around the central shaft of fixes sleeve 2, and intersect at Central axis.It is ellipsoid since electrode cap needs the one end to repair a die, to make the shape of blade 1 be adapted with electrode cap, Three the first top surfaces 11 are located on same ellipsoid, and the center of the ellipsoid is located on the central shaft of fixes sleeve 2, ensures When repairing a die to electrode cap cutting, the center deviation that repairs a die will not be led to, form variations influence to use after repairing a die so as to cause electrode cap.

First top surface 11 and the first inclined-plane 12 are crossed to form the first blade 14, and shape is intersected in the first top surface 11 with the second inclined-plane 13 At third blade 15, the first blade 14 and third blade 15 of three blades 1 are set around the central shaft uniform intervals of fixes sleeve 2 It sets, and on the above-mentioned ellipsoid, when ensureing that the first blade 14 or third blade 15 repair a die to electrode cap, three blades 1 First blade 14 or third blade 15 can simultaneously repair a die to electrode cap, and electrode cap repair a die after shape meet electrode cap Requirement.

Each blade 1 is plane symmetrical structure, and has first plane of symmetry and second plane of symmetry, wherein second plane of symmetry Across the first top surface 11 and the central shaft of fixes sleeve 2, the first inclined-plane 12 and 13 opposite second plane of symmetry of the second inclined-plane are symmetrically set It sets, and keeps the first blade 14 and third blade 15 symmetrical with respect to second plane of symmetry, therefore, the first blade 14 and third blade 15 For cutting direction on the contrary, in synchronization, the first blade 14 and third blade 15 will not be carried out at the same time cutting.In the present embodiment, The cutting angle of first blade 14 is 5 ° -20 °, and preferably 15 °.Two blades are set on the same blade 1, can make to repair Mould knife repairs a die to electrode cap rotating forward or rotate backward Shi Junneng, extends electrode and repairs a die the service life of knife.

Fig. 2 is that electrode provided by the utility model repairs a die the sectional view of knife, from figure 2 it can be seen that the setting of blade 1 is solid Sleeve 2 is determined along the centre position of short transverse, and its first plane of symmetry perpendicular to central shaft and passes through 2 short transverse of fixes sleeve Middle face.Fig. 3 is the partial enlarged view of Fig. 2, from figure 3, it can be seen that each 1 side far from the first top surface 11 of blade is opposite First plane of symmetry is symmetrically arranged with the second top surface 16, and 16 both sides of the second top surface are connected with third inclined-plane 17 and the 4th inclined-plane 18, and Third inclined-plane 17 and the first inclined-plane 12 and the 4th inclined-plane 18 and the second inclined-plane 13 are arranged with respect to first plane of symmetry respectively.Wherein, Two top surfaces 16 are crossed to form the second blade 19 with third inclined-plane 17, and the second top surface 16 and the 4th inclined-plane 18 are crossed to form the 4th blade 110.The setting of second blade 19 and the 4th blade 110 can make electrode repair a die knife both ends in synchronization respectively to two electricity Polar cap repairs a die, and improves the efficiency to repair a die.

To enhance the contact area of blade 1 and fixes sleeve 2, one end that blade 1 is connected to fixes sleeve 2 is cuboid, So as to while ensureing 1 performance of blade, enhance the rigidity of blade 1.

In the present embodiment, the quantity of blade 1 is three, can also select to be set as two, four or other quantity Blade number.

Electrode provided by the utility model repairs a die knife, and since blade 1 and fixes sleeve 2 are integrally formed, avoiding blade 1 needs Caused knife rest on knife rest is mounted on to connect trouble with blade 1 and be susceptible to the problem of blade 1 connect loosening with knife rest； It is provided with three blades 1 in fixes sleeve 2, the efficiency that electrode cap repairs a die can be improved, and ensure electrode cap repairs a die center not It can deviate, to ensure that the quality that repairs a die of electrode cap；Two in each blade 1 are respectively set blade, and one can be made to repair Mould knife synchronization respectively repairs a die to two electrode caps；Two blades are set in the same side of each blade 1, electricity can be made The pole knife that repairs a die can repair a die in the case where rotating forward and anti-dress, delay the service life for the knife that repairs a die.

Note that above are only the preferred embodiment and institute's application technology principle of the utility model.Those skilled in the art's meeting Understand, the utility model is not limited to specific embodiment described here, can carry out for a person skilled in the art various bright Aobvious variation is readjusted and is substituted without departing from the scope of protection of the utility model.Therefore, although passing through above example The utility model is described in further detail, but the utility model is not limited only to above example, is not departing from Can also include other more equivalent embodiments in the case that the utility model is conceived, and the scope of the utility model is by appended Right determine.
