Abstract
The invention relates to a molybdenum-based tappet used for hot perforation of stainless steel, comprising a tappet, a hollow mandril and a loose joint connecting the tappet with the mandril, wherein the loose joint comprises a tappet loose joint connected with the tappet by virtue of a screw thread and a mandril loose joint connected with the mandril by virtue of the screw thread, the tappet loose joint is connected with the mandril loose joint by virtue of the screw thread, the tappet loose joint and the mandril loose joint are both hollow pipes, and the pipe wall of the tappet loose joint is provided with at least one through hole. The molybdenum-based tappet provided by the invention has a simple structure, and the pipe wall of the tappet loose joint is additionally provided with the through hole used for discharging partial cooling water, thus the effect of cooling the tappet is achieved; meanwhile, appropriate cooling water is beneficial to rapid cooling of the inner wall of a stainless steel pipe, thus the aim of solid solution strengthening is achieved and the qualifying rate of products is improved.
Description
Technical field
The present invention relates to stainless steel hot perforating apparatus technical field, especially a kind of molybdenum base top.
Background technology
Molybdenum base top adopts the molybdenum powder raw material to add rare earth material, be processed into through operations such as batch mixing, moulding, sharp processing, high temperature sinterings, molybdenum alloy has good heat conduction, electric conductivity and the low coefficient of expansion, at high temperature (1100～1650 ℃) still have higher intensity, are mainly used in the hot-puncturing process work of seamless steel pipe under high-temperature severe environment such as stainless steel, steel, bearing steel and high-temperature alloy steel.
The molybdenum base comes directly towards when hot-puncturing process is worked, under the adverse circumstances of HTHP and violent friction, and the too high generation viscosity of temperature of molybdenum base top, scratch steel tube inner hole and make the steel pipe inwall crackle occur, produce substandard products, because of the stainless steel price higher, in case substandard products occur, loss will be very big.Therefore need cool off molybdenum base top when perforation, prior art adopts water-cooling pattern, but can not well cool off molybdenum base top.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in the prior art, a kind of molybdenum base top is provided, cooling effect is better.
The technical solution adopted for the present invention to solve the technical problems is: a kind of molybdenum base top, comprise top, hollow push rod and the loose joint that connects top and push rod, described loose joint comprises top loose joint that is threaded with the top and the push rod loose joint that is threaded with push rod, the top loose joint is threaded with the push rod loose joint, loose joint of described top and push rod loose joint are hollow pipe, and the tube wall of described top loose joint has at least one through hole.
Further, described number of openings is three.
The invention has the beneficial effects as follows, molybdenum base top structure of the present invention is simple, on top loose joint tube wall, set up through hole, be used for the discharge section cooling water, reach the effect that reduces the top temperature, suitable cooling water helps the purpose that the quick cooling of stainless steel inside pipe wall reaches solution strengthening simultaneously, improves the qualification rate of product.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the most preferred embodiment of molybdenum base of the present invention top.
Among the figure: 1. come directly towards 2. top loose joint, 21. through holes, 3. push rod loose joint, 4. push rod.
The specific embodiment
As shown in Figure 1, the most preferred embodiment of molybdenum base of the present invention top, a kind of molybdenum base top, comprise top 1, hollow push rod 4 and the loose joint that connects top 1 and push rod 4, loose joint comprises and the push rod loose joint 3 that comes directly towards the 1 top loose joint 2 that is threaded and be threaded with push rod 4, top loose joint 2 is threaded with push rod loose joint 3, and top loose joint 2 and push rod loose joint 3 are hollow pipe, and the tube wall of top loose joint 2 has at least one through hole 21.Preferred plan, through hole 21 quantity are three.
When actual production, feed cooling water pipeline in the hollow push rod 4, can regulate cooling effectiveness by control hydraulic pressure, most of water flows out by hollow push rod 4, and part water flows out by the through hole in the loose joint 2 of top 21, is all cooled off inside and outside making top 1, also make simultaneously the stainless steel inside pipe wall cooling, help inwall and cool off solution strengthening fast, reduce waster, improve the qualification rate of product.
Claims (2)
1. a molybdenum base comes directly towards, comprise top (1), hollow push rod (4) and the loose joint that connects top (1) and push rod (4), described loose joint comprises top loose joint (2) that is threaded with top (1) and the push rod loose joint (3) that is threaded with push rod (4), top loose joint (2) is threaded with push rod loose joint (3), it is characterized in that: described top loose joint (2) and push rod loose joint (3) are hollow pipe, and the tube wall of described top loose joint (2) has at least one through hole (21).
