Abstract
The invention discloses an ejector header cooling device of a seamless tube perforating machine. The ejector header cooling device of the seamless tube perforating machine comprises a perforating trolley body, a hollow rotation main shaft and a cooling water pipe. The rotation main shaft is arranged in the perforating trolley body in a rotation mode through a bearing. The tail of the perforating trolley body is provided with a connection frame. A sealing cover is installed on an end portion of the connection frame. A through hole is formed in the sealing cover. The cooling water pipe penetrates through the through hole and penetrates into the rotation main shaft to reach the position of the ejector header. The cooling water pipe penetrates out of one end of the connection frame and is connected with a water intake pipe through a rotation joint. The rotation joint is additionally arranged on the ejector header cooling device of the seamless tube perforating machine. In the process of milling, the ejector header rotates to drive the cooling water pipe to rotate along with the rotation main shaft. The cooling water is prevented from breaking in the milling process, pressure of water currents is maintained, the temperature of the ejector header is reduced, the maintaining cost is reduced, the fault time is reduced, the working rate is effectively improved and the capacity is improved.
Description
Technical field
The present invention relates to a kind of seamless pipe punch, relate in particular to a kind of seamless tube perforator plug cooling device.
Background technology
Hot rolling is to be formed by rolled by piercing mill without meeting steel pipe, the basic craft course of drilling/rolling is: by roll, guide plate, top, form a blind bore type, carry out continuous modification in the zone that high-temperature metal forms at this pass, finally from solid pipe, shut out hollow hollow billet.Wherein, roll, guide plate fixedly mount relatively according to technological requirement, and top is installed on ejector rob trolley provided push rod, with the action request of rolling cycle, are rolled the change of position and the rear bit period of work.Due to solid pipe is bored a hole into to hollow hollow billet, flow of metal mainly concentrates on top to be carried out; Come directly towards at high-temperature, high pressure operation simultaneously, thereby be easy to wearing and tearing or nose is pressed heap, cause top not use for a long time, top is changed frequent.Need to carry out to top water cooling when working.
At present, traditional seamless tube perforator plug cooling device as shown in Figure 1, Fig. 1 is the structural representation of traditional seamless tube perforator plug cooling device, it comprises perforating trolley car body 10, the rotary main shaft 11 of hollow, cooling water pipe 12 and fixed support 13, described rotary main shaft 11 rotatably is arranged in perforating trolley car body 10 by bearing 14, described cooling water pipe 12 penetrates position, rotary main shaft 11 interior arrival top from the afterbody of perforating trolley car body 10, and described cooling water pipe 12 is connected on perforating trolley car body 10 by fixed support 13, the connected mode of this kind of structure cooling water pipe 12, in the concrete course of work, can not in the operation of rolling, rotate with rotary main shaft 11, cause cooling water pipe 12 often to rupture, cause the seamless pipe punch to work, affect its efficiency.
Summary of the invention
The object of the present invention is to provide a kind of seamless tube perforator plug cooling device, it has reduction fault time, has improved efficiency, promotes the characteristics of production capacity, to solve the problems referred to above that in prior art, the seamless tube perforator plug cooling device exists.
