Abstract

The utility model discloses a seamless pipe perforating machine top head cooling device. The seamless pipe perforating machine top head cooling device comprises a perforating cart body, a hollow rotating main shaft and a cooling water pipe. The rotating main shaft is rotably arranged in the perforating cart body through a bearing. A connecting frame is installed on the tail portion of the perforating cart body. A sealing cover is installed on the end portion of the connecting frame and provided with a through hole. The cooling water pipe penetrates through the through hole and penetrates into the rotating main shaft to arrive at a top head. One end, stretching out of the connecting frame, of the cooling water pipe is connected with a water inlet pipe through a rotating connector. In the rolling process, because the rotating connector is additionally arranged on the seamless pipe perforating machine top head cooling device, the top head rotates to drive the cooling water pipe to rotate together with the rotating main shaft, the cooling water pipe is prevented from cracking, pressure of water flow can be kept, and the temperature of the top head is reduced. The seamless pipe perforating machine top head cooling device reduces maintenance cost and fault time and improves working efficiency and productivity.

Description

A kind of seamless tube perforator plug cooling device
Technical field
The utility model relates to a kind of seamless pipe punch, relates 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, in the region that high-temperature metal forms at this pass, carry out continuous modification, 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 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 when working, carry out to top water cooling.
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 is rotatably 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 seamless pipe punch to work, affect its efficiency.
Utility model content
The purpose of this utility model is to provide a kind of seamless tube perforator plug cooling device, it has reduction fault time, improve efficiency, promoted the feature of production capacity, to solve the problems referred to above that in prior art, seamless tube perforator plug cooling device exists.
For reaching this object, the utility model by the following technical solutions:
A kind of seamless tube perforator plug cooling device, it comprises rotary main shaft and the cooling water pipe of perforating trolley car body, hollow, described rotary main shaft is rotatably arranged in perforating trolley car body by bearing, wherein, the afterbody of described perforating trolley car body is provided with link, the end of described link is provided with seal cover, on described seal cover, offer through hole, described cooling water pipe is through described through hole and penetrate and arrive position, top in rotary main shaft, and one end that described cooling water pipe stretches out link connects water inlet pipe by swivel joint.
Especially, between described link and cooling water pipe, lubricating bearings is installed.
Especially, on described link, offer connecting hole, corresponding to offering screwed hole on perforating trolley car body, connecting bolt lock onto in screwed hole link is fixed on to perforating trolley car body through described connecting hole.
Especially, between described through hole and cooling water pipe, be provided with rotating water sealing.
The beneficial effects of the utility model are, compared with prior art described seamless tube perforator plug cooling device installs swivel joint additional, in the operation of rolling, top is rotated and is driven cooling water pipe to rotate with rotary main shaft, avoid cooling water pipe fracture in the operation of rolling, and can keep water flow pressure, reduce top temperature.Not only reduced maintenance cost; And reduce fault time, improved efficiency, promoted production capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional seamless tube perforator plug cooling device;
Fig. 2 is the structural representation of the seamless tube perforator plug cooling device that provides of the utility model specific embodiment 1.
The specific embodiment
