Abstract
The utility model provides a perforation top combined connector. The connector is a hollow pipe and comprises a connection section in the middle and thread sections which are arranged at the two sides of the connection section; the thread arranged at the thread section which is arranged at one side of the connector is a ladder buckle type; the periphery of the thread section at the other side of the connector is provided with a plurality of external spraying overflow water troughs at equal intervals; the periphery of the connection section of the connector is provided with symmetrical spigots. The perforation top combined connector has the effects that the perforation top combined connector reduces the top disassembly time from about 30 minutes to less than 5 minutes, complies with the processing requirement of internal and external cooling of the top, and improves the production efficiency. Meanwhile, the tonnage steel cost of the consumption of the top is controlled to be 0.3kg/ton pipe from the original 0,8kg/ton pipe.
Description
Technical field
The utility model relates to a kind of metallurgy industry perforation special connector, particularly a kind of inside and outside water-cooled perforating head unit connector of perforating head that is applicable to.
Background technology
In the production process of seamless steel pipe, first road distortion operation perforation unit adopts the circulation of many tops rolling mostly, because the production model of the small batch of ASSEL unit, many kinds, many specifications, the top is changed frequent, comes directly towards this unit production model of circulation rolling mode incompatibility more.In view of above reason, the water-cooled top is rolling in proposing to adopt, in implementing improved process,, because the wearing and tearing of top, the loading and unloading top becomes a great problem, top of every dismounting will both influence output, operating efficiency more than 30 minutes, had increased working strength of workers again.For this reason, need a kind of special connector of exploitation, to separate the matter of great urgency.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the utility model purpose provides a kind of perforating head unit connector, is beneficial to enhance productivity, and alleviates labor intensity of operating personnel.
For achieving the above object, the technical solution adopted in the utility model provides a kind of perforating head unit connector, wherein: this connector is a hollow pipe fitting, the linkage section in the middle of this connector comprises and the thread segment of linkage section both sides, the screw thread of described connector one side thread segment is the buttress thread type, equally spaced on the periphery of described connector opposite side thread segment to be provided with a plurality of outer spray spilling waters poor, is provided with the seam of symmetry on the linkage section periphery of described connector.
The dismounting that effect of the present utility model is to use this perforating head unit connector to come directly towards dropped to below 5 minutes by original about 30 minutes, can satisfy the technological requirement of the inside and outside cooling in top, enhanced productivity.Ding Tou consumption simultaneously also controls to 0.3kg/ ton pipe by original ton steel cost 0.8kg/ ton pipe.

The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the utility model perforating head unit connector structure.
As Figure 1-3, the utility model perforating head unit connector is a hollow pipe fitting, the linkage section 1 in the middle of this connector comprises and the thread segment 2 of linkage section both sides, the screw thread of described connector one side thread segment 2 is the buttress thread type, the periphery of described connector opposite side thread segment is provided with a plurality of equally spaced outer spray spilling waters poor 3, so that four poor being advisable of outer spray spilling waters to be set, on the periphery of the linkage section of described connector, be provided with the seam 4 of symmetry.
During the utility model perforating head unit connector uses push rod connector and this perforating head unit connector will be come directly towards by the trapezoidal thread screw thread and push rod connects as one, supply water by inner water cooling pipe in the use, both satisfied the inner cooling in top, can be pickled with grains or in wine by the outer spray spilling water of perforating head unit connector again reaches the purpose that makes the top external refrigeration.
When in the operation of rolling, needing the dismounting top, open mouth tongs are stuck in seam 4 places of perforating head unit connector, another open mouth tongs are stuck on the top, because of interior water-cooled effect is more abundant, the heading joint expanded by heating is less, and two open mouth tongs are exerted oneself round about, can disassemble the heavier top of wearing and tearing, save the take-down time, reduced worker's labour intensity, satisfied the requirement of changing the top in the production process fast.
The perforating head unit connector mainly sprays the appropriate design of the poor and trapezoidal special screw thread of spilling water outward by the top connector, reaching the top can inside and outside cooling can change function of use again fast.
Claims (1)
1, a kind of perforating head unit connector, it is characterized in that: this connector is a hollow pipe fitting, the linkage section in the middle of this connector comprises and the thread segment of linkage section both sides, the screw thread of described connector one side thread segment is the buttress thread type, equally spaced on the periphery of described connector opposite side thread segment to be provided with a plurality of outer spray spilling waters poor, is provided with the seam of symmetry on the periphery of described connector linkage section.
