Abstract
The utility model relates to the field of seamless steel tube manufacturing equipment, in particular to a punching ejector head of a surface strengthened seamless steel tube rolling mill. The punching ejector head comprises an ejector head body, an assembly cavity and a heat dissipation cavity are formed in the ejector head body along the axis and are communicated with each other, the assembly cavity is formed in the tail of the ejector head body, the heat dissipation cavity is formed in the head of the ejector head body, and an anti-abrasion layer is arranged on the outer surface of the ejector head body. The punching ejector head has the advantages that the superstrong anti-abrasion layer is arranged on the outer surface of the ejector head body to enhance the strength of the ejector head body and prolong the service life of the ejector head body, and after the ejector head is partially abraded, an ineffective portion can be repaired in a welding mode to ensure cyclic utilization of the ejector head, so that the punching ejector head has repairability, saves energy, reduces consumption and meets the requirement for circular economy in China.
Description
Technical field
The utility model relates to seamless steel pipe manufacturing equipment field, relates in particular to a kind of surface peening slitless tube mill perforating head.
Background technology
Top, is the key tool in seamless steel tube production, the quality of its quality, and the length in service life, directly affects the Yield and quality of steel pipe's production and the economic benefit of enterprise.Hollow hollow billet, piercing in seamless steel pipe process, is made by solid pipe in top, and the distortion of metal is mainly carried out on top.The working condition of perforating head is quite severe, not only will bear powerful axial compressive force, and will overcome the powerful distortion friction producing between inwall.Thereby can think, perforating head is worked under low-cycle fatigue condition, thus its wearing and tearing to scrap be the main cause that affects service life.It is short that routine comes directly towards not only service life, and cannot repair after damaging, and is to guarantee normal continuity of producing, and needs a large amount of depot spare parts, and this is a great financial burden for using producer.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of surface peening slitless tube mill perforating head, has strengthened the main body intensity of top, has overcome and in prior art, has come directly towards short defect in service life.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of surface peening slitless tube mill perforating head, comprise top body, described top body interior is provided with the assembly cavity and the heat radiation chamber that are conducted along its axle center, described assembly cavity is arranged on the afterbody of described top body, described heat radiation chamber is arranged on the head of described top body, and the outer surface of described top body is provided with wearing layer.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described wearing layer is in cobalt-based, to add carbide alloy phase.
Further, described welding wear-resistant layer is connected on the outer surface of described top body.
The beneficial effects of the utility model are: the outer surface of top described in the utility model is provided with superpower wear-resistant layer, strengthen the intensity of top main body, heighten the service life of top, and can adopt welding manner reparation to failure site after the concentrated wear of top described in the utility model, guarantee recycling of top, there is recoverability, energy-saving and cost-reducing, meet the requirement of national recycling economy.
Accompanying drawing explanation
Fig. 1 is the cutaway view of a kind of surface peening slitless tube mill of the utility model perforating head.
In accompanying drawing, the list of parts of each label representative is as follows:
1, top body, 2, assembly cavity, 3, heat radiation chamber, 4, wearing layer.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of surface peening slitless tube mill perforating head described in the utility model, comprise top body 1, body 1 inside, described top is provided with the assembly cavity 2 and the heat radiation chamber 3 that are conducted along its axle center, described assembly cavity 2 is arranged on the afterbody of described top body 1, described heat radiation chamber 3 is arranged on the head of described top body 1, and the outer surface of described top body 1 is provided with wearing layer 5.Described wearing layer 5 adds carbide alloy phase, the such as carbide alloy such as WC, BN phase in cobalt-based.Described welding wear-resistant layer is connected on the outer surface of described top body 1.
Top is assemblied on machine push rod by assembly cavity 2, piercing in seamless steel pipe process, solid pipe is made to hollow hollow billet, the wearing layer 5 that comes directly towards this external surface is main friction and heating faces, in welding after superhard wearing layer 5, make the intensity of perforating head obtain significantly improving, not only can meet the necessary rigidity of perforation, also there is good resistance to elevated temperatures simultaneously, in the time piercing seamless steel pipe, reduce the infringement to top body 1, thereby improved the service life of top.May there is concentrated wear in wearing layer 5, can repair it by the mode of welding after use after a while, guaranteed recycling of top.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (2)
1. a surface peening slitless tube mill perforating head, comprise top body, described top body interior is provided with the assembly cavity and the heat radiation chamber that are conducted along its axle center, described assembly cavity is arranged on the afterbody of described top body, described heat radiation chamber is arranged on the head of described top body, it is characterized in that, on the outer surface of described top body, be welded with wearing layer.
2. a kind of surface peening slitless tube mill perforating head according to claim 1, is characterized in that, described wearing layer is in cobalt-based, to add carbide alloy phase.
