Examples

The embodiment provides a two-edge tool assembly of an automatic chip-breaking buckle mounting interface of an electrode cap, as shown in fig. 7, which comprises two edges 10, namely a first edge 20 and a second edge 30; the first edge 20 and the second edge 30 are symmetrically arranged; the first edge 20 and the second edge 30 cooperate with each other to form a blade structure; the blade structure is used for grinding the electrode tip.

The blade 10 comprises a base 11; one end of the base body 11 forms a first matching end part 13 used for matching with other blades 10, and the other end forms a second matching end part 14 used for installation; the first matching end part 13 of the first blade 20 is matched with the base body 11 of the second blade 30 in a fitting manner; similarly, the first engagement end 13 of the second blade 30 abuts the base 11 of the first blade 20. The two first engagement ends 13 are interfitted in the manner described above to form an integral blade 10 structure.

The first fitting end portion 13 includes a root portion 131 and an end portion 132, and is formed in a wide to narrow shape from the root portion 131 to the end portion 132; root 131 is wider, and area of contact is great for strengthen laminating intensity, and then strengthen the cooperation intensity for sword 10 structure is in the rotary grinding process, and is difficult for the dispersion.

The end portion 132 can be made as narrow as possible while ensuring the fitting strength, thereby saving unnecessary use of materials.

Meanwhile, the top surface of the end portion 132 is necessarily provided in a notch shape to ensure that the curved surface formed during the rotation of the blade 10 structure is curved or spherical to ensure the curved or spherical shape of the electrode tip after grinding.

Specifically, the first mating end 13 is provided in a wedge shape.

Further, the ground wall surface 12 of the base 11 is provided as an arc-shaped surface as a whole; for securing the shape of the ground electrode tip.

Specifically, the grinding wall surface 12 includes several sub-wall surfaces 121 arranged along the arc extending direction of the grinding wall surface 12. A chip separation groove 122 is formed between the sub-wall surfaces 121; during the grinding of the electrode head, fine metal chips are produced, which, under the action of the constantly rotating blade 10, have a tendency to move. The tendency of centrifugal motion is not used in the prior art to remove swarf. In the prior art, a mode of arranging the chip removal through hole is often adopted, and metal chips are pushed into the chip removal hole by pushing force generated by the blade 10 scratching the surface of the electrode head so as to be removed. The chip dividing groove 122 is used for removing metal chips in a short time after the metal chips are generated, so that the metal chips are prevented from staying on the surface of the electrode head, and scratches can be reduced.

Of course, as shown in fig. 1-3, the present application also provides a chip evacuation space, similar to the chip evacuation holes of the prior art. The swarf is removed as smoothly as possible by the cooperation of the swarf removal space (or the swarf removal hole) and the swarf divider 122.

Specifically, the two-edge tool assembly of the automatic chip breaking and buckling mounting interface of the electrode cap comprises a mounting seat 50 and a blade structure mounted on the mounting seat 50; the mounting seat 50 is provided with through holes 51 distributed along the axial direction; the blade structure and the through hole 51 form a right-angle chip breaker 60 for discharging metal chips; the grinding wall surface 12 of the blade structure is provided with a linear chip breaker groove 122 capable of discharging metal chips in cooperation with the chip breaker groove 60.

Specifically, as shown in fig. 4-6, the mounting seat includes an upper seat body 53 and a lower seat body 54, and both the lower seat body 54 and the upper seat body 53 are provided with threaded holes; the upper and

lower seats

53 and 54 are fixedly coupled by means of screw holes and bolts 52. In this way, the mounting and removal of the blade structure can be facilitated.

As shown in fig. 8, the blade 10 is rotated to form a grinding zone 40, and the size and shape of the grinding zone 40 are the size and shape of the ground electrode tip. The cross-sectional shape of the grinding zone 40 forms a circular area with the grinding surfaces arranged in a radial direction of the circular area, gradually widening from the center of the circle to the circular boundary.

The coplanar portions of the bases 11 of the first and

second edges

20, 30 are distributed along the diameter of the circular area; the grinding wall surfaces 12 of the first and

second blades

20 and 30 are provided on both sides of the diameter. In the prior art, the grinding wall surface 12 of the blade 10 is usually simply arranged along the radial direction with equal width, and in order to realize grinding, more blades 10 are required, such as a 3-blade 10 grinding tool possibly available on the market and a 4-blade 10 grinding tool indicated in the background art.

This application adopts first sword 20 and the coplane of second sword 30 to distribute along the diameter, and both sides are located respectively to every grinding wall 12 utilizes the grinding force coping electrode head surface of slope by narrow to wide configuration form, not only more laborsaving, and the vibrational motion who takes place is weak (is favorable to protecting cutting edge 10 not to break).

In order to achieve the technical effects of saving labor and reducing vibration, the key point is that the end 132 of the first blade 20 and/or the second blade 30 needs to be arranged away from the center of the circular area; it is also necessary to set the grinding wall surface 12 in a narrow to wide shape; namely non-concentric sectors and eccentric sectors.

Specifically, the chip dividing grooves 122 are arranged non-perpendicularly to the diameter direction within the angle range of 0-180 degrees; to better conform to the chip removal direction (i.e., the chip-dividing flutes 122 are inclined in the tangential direction of rotation of the blade 10 as described in the claims).

The second matching end part 14 is matched with a mounting hole of the mounting seat to realize the mounting of the blade 10 structure; in the actual use process, the mounting seat is connected with a power device, the power device drives the mounting seat to rotate, the mounting seat drives the blade 10 to rotate, and then the electrode tip grinding is achieved.

Specifically, the mating end 132 is provided in a hook shape; the hook-shaped opening faces the direction of the blade 10 structure acted by the mounting seat, so that the matching strength of the hook-shaped opening and the mounting seat is enhanced, and the integral stability is improved.

Specifically, the mount pad includes upper seat body and lower seat body, and upper seat body and lower seat body are integrative structure. The upper seat body and the lower seat body can be connected through bolts. Through the upper seat body and the lower seat body of the integrated structure, the installation strength and the concentricity of the blade 10 structure are improved, so that the precision in the rotary grinding process is ensured.

The blade 10 is made of tungsten steel (cemented carbide) or powder high-speed steel, and since the tip is generally made of chromium zirconium copper, it has properties of high hardness and high softening temperature. For both properties, the material of the construction of the edge 10 is higher than that of the chromium-zirconium-copper alloy at least in terms of hardness and is capable of higher heat resistance (because more heat is generated during grinding). Therefore, the tungsten steel blade 10 structure is adopted in the application, has the performances of high hardness, wear resistance, high strength, good toughness and high temperature resistance, can be normally used especially at the high temperature of 500 ℃, and can be widely applied.

Besides the tungsten steel material, other alloys with high hardness and high temperature resistance can be adopted; the key point is that: the material of the blade 10 structure needs to be higher than that of chromium-zirconium-copper alloy in hardness; capable of withstanding temperatures of at least 500 c.

Furthermore, the smoothness of the electrode tip after grinding by the present application does not exceed 1.2Ra.
