Abstract
The utility model discloses a high performance top of perforating, including straightway, inclined plane section, circular arc section, head, its characterized in that: the arc section is provided with a wear-resistant layer in a surfacing mode, the wear-resistant layer and the inclined plane section are provided with spiral grooves, and the straight line section, the spiral grooves and the head are provided with a nickel base layer. The utility model has the advantages of ingenious and reasonable structure, and the wear-resistant layer is built up on the arc section, so that the wear-resistant performance of the arc section is improved; a spiral groove is turned on the wear-resistant layer, so that the contact area is effectively increased; the straight line section, the spiral groove and the head of the ejector are provided with the nickel-based layers, so that the high-temperature resistance and the wear resistance are improved.
Description
Technical Field
The utility model relates to a seamless steel pipe production field especially relates to a high performance piercing point.
Background
The piercing plug is one of key parts for seamless steel tube production, and has poor working conditions during piercing, so that the piercing plug needs to be in gapless contact with a high-temperature round tube blank, and during finish rolling, the head of the piercing plug has a temperature as high as about 1300 ℃ and simultaneously needs to bear the friction force and extrusion force from the round tube blank, so that the quality and the service life of the piercing plug directly influence the quality and the cost of producing a hollow billet by a piercing mill. In the prior art, the piercing plug is very easy to wear and corrode, and the service life is short. Therefore, there is a need for a high performance piercing point that has a long useful life.
Disclosure of Invention
The purpose of the utility model is to solve the technical problem and provide a high-performance piercing point.
In order to realize the technical purpose, reach foretell technical requirement, the utility model discloses the technical scheme who adopts is:
high performance perforation top, including straightway, inclined plane section, circular arc section, head, its characterized in that: the arc section is provided with a wear-resistant layer in a surfacing mode, the wear-resistant layer and the inclined plane section are provided with spiral grooves, and the straight line section, the spiral grooves and the head are provided with a nickel base layer.
Preferably: and a groove for surfacing a wear-resistant layer is formed on the arc section base body.
Preferably: the bottom of the spiral groove is provided with an arc, and the groove angle alpha is set to be 30-40 degrees.
Compared with the traditional structure, the beneficial effects of the utility model are that: the wear-resistant layer is overlaid on the arc section, so that the wear resistance of the arc section is improved; a spiral groove is turned on the wear-resistant layer, so that the contact area is effectively increased; the straight line section, the spiral groove and the head of the ejector are provided with the nickel-based layers, so that the high-temperature resistance and the wear resistance are improved.

in the figure: 1. straight line segment, 2 bevel segment, 3 circular arc segment, 4 head, 5 wear-resistant layer, 6 spiral groove and 7 nickel base layer.
Detailed Description
The present invention will be further explained below.
Referring to the attached drawings, the high-performance perforating plug comprises a straight line segment 1, an inclined plane segment 2, an arc segment 3 and a head 4, and is characterized in that: the arc section 3 is provided with a wear-resistant layer 5 in a surfacing mode, spiral grooves 6 are formed in the wear-resistant layer 5 and the inclined plane section 2, and the straight line section 1, the spiral grooves 6 and the head 4 are provided with a nickel base layer 7.
In the preferred embodiment, a groove for surfacing a wear-resistant layer 5 is formed on the base body of the arc section 3.
In the preferred embodiment, the bottom of the spiral groove 6 is provided with an arc, and the groove angle α 61 is set to be 30-40 °.
When the utility model is processed, a groove with the depth of 3 mm is turned on the top arc section, then the wear-resistant layer is built up, a special forming turning tool is used for turning a spiral groove on the surface of the wear-resistant layer and the inclined plane section, the tool tip is ensured to feed along the arc center (each groove has the same groove type), and the groove center of the inclined plane section is arranged on the arc center; and spraying high-temperature-resistant and wear-resistant nickel base on the head, the wear-resistant layer, the inclined plane section and the straight line section.
The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
