Abstract
The invention discloses a tube detaching device used in a perforator and being capable of cooling the piercing plug of a perforator, which relates to the device for cooling the piercing plug of a hot rolling perforator and tube detaching equipment. In prior art, a cooling water tank and a tube detaching device take up two positions respectively, after perforation, the length of a tubular billet is up to 10 meter with which a mandril and an outlet platform both with enough length are needed to be matched. The increased length of mandril not only results in the poor rigidity of the mandril, influences the quality of wall thickness of the tubular billet, but also results in lengthening of the outlet platform and enlarging the land occupation. In the invention, the cooling water tank and the tube detaching device are designed in integration; a water nozzle is positioned in the cooling water tank; the water nozzle is connected with flow pipe through a flange; an offlet is positioned at the bottom of the cooling water tank; therefore, one position can realize two functions that are tube detaching and piercing plug cooling, which not only reduces the length of the mandril, enhances the rigidity of the mandril, improves the uniformity of wall thickness of the tubular billet but also reduces the lengths of a first and a second segments of the outlet platform, thus ensuring the more compact structure of the device.
Description
Technical field
The invention belongs to the hot-puncturing process machine equipment, particularly tube apparatus is cooled off and taken off in one section top of the outlet of the hot-rolling perforation machine in seamless steel tube production unit platform.
Background technology
Hot-puncturing process is a most important operation in the seamless steel tube production, is first procedure of flow of metal.The effect of hot-rolling perforation machine in the seamless steel tube production unit is that solid blank pierced billet is become hollow hollow billet.Perforation procedure is to be rotated by piercer roll, the mandril anti-thrust trolley that the outlet platform is two sections drives the top, push rod moves to working position, and mandril anti-thrust trolley is locked in this position, the pipe that heats pushes away the base hydraulic cylinder by import desk pipe is pushed the punch main engine bed, pipe is nipped, is bored a hole, and behind rolling the finishing, the blocking device that the outlet platform is two sections is opened, mandril anti-thrust trolley runs to the position, back, by taking off pipe unit hollow billet is separated with the top.Because in the perforation procedure, the top temperature raises, so a top cooling water tank is installed usually, whenever wear a steel pipe after taking off pipe unit, utilize the intermittent time that the top is cooled off.
Along with the progress of puncturing technique, perforation back hollow billet length has reached more than 10 meters, just needs sufficiently long push rod this moment and export platform to match with it for one section, two sections.If adopt one type of prior art syringe (as accompanying drawing 1), that is: cooling water tank II and take off pipe unit I and occupy two stations respectively.After push rod was elongated, not only its rigidity meeting variation came directly towards during perforation and easily departs from rolling centerline, causes the hollow billet wall unevenness, and can make one section, two sections lengthenings of outlet platform, and floor space is big.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of pipe unit that takes off that punch can cool off the top that is used for is provided, can shorten push rod length, improve push rod rigidity, improve the wall unevenness of hollow billet; Shorten one section of platform of punch outlet, two segment length, make equipment compact more.
Technical scheme of the present invention for achieving the above object is:
A kind ofly be used for the pipe unit that takes off that punch can cool off the top, comprise cooling water tank, it is characterized in that: the front panel design of described cooling water tank is to take off the support of pipe die, taking off pipe die is installed on the water tank front panel, fix by briquetting, sparge pipe is housed in the cooling water tank, and sparge pipe links to each other with feed pipe by flange, and adjutage is installed in the cooling water tank bottom.
Described sparge pipe is made up of two semicircle water pipes that have nozzle.
Be stamped cover plate on the described cooling water tank.
The present invention compared with prior art since with cooling water tank with take off pipe die and be designed to one, when taking off pipe die the hollow billet head is blocked the location, the top just enters water tank after die orifice is extracted out, in the water tank sparge pipe from around to the top water spray, realize the top cooling.Therefore, the present invention can realize taking off pipe, two functions in cooling top by a station, not only can shorten push rod length, improves push rod rigidity, and rolling centerline is departed from the top when avoiding boring a hole, and improves the evenness of wall thickness of hollow billet; And shortened one section of platform of punch outlet, two segment length, make equipment compact more.
With certain φ of factory 177 perforation unit is example:
If adopt one type of prior art syringe (as accompanying drawing 1), long 10 meters of perforation back hollow billet, push rod length is 16.42 meters, the one section back length of walking the wire is 1.52 meters, 30 meters of two segment length.
Use device of the present invention (as accompanying drawing 2.3.4), long 10 meters of perforation back hollow billet, push rod length becomes 15.9 meters, has shortened 0.52 meter, and the outlet platform shortens 1.3 meters for one section, two sections.
Description of drawings:
Fig. 1 is the structural representation that has cooling water tank now, takes off pipe unit;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is the vertical view of Fig. 2;
Fig. 4 is the side view of Fig. 2.
The present invention is further illustrated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
Shown in Fig. 2,3,4, a kind ofly be used for the pipe unit that takes off that punch can cool off the top, be front panel design with cooling water tank 1 for taking off the pipe die support, take off pipe die 5 and be installed on the water tank front panel, fixing by briquetting 3.Taking off pipe die is the equipment that after perforation finishes hollow billet is separated with top 9, push rod, and it mainly acts on is hollow billet 10 heads to be blocked make the hollow billet location, allows top, push rod to extract out by die orifice.The top just enters water tank after die orifice is extracted out, sparge pipe 2 is housed in the water tank, and sparge pipe links to each other with the workshop feed pipe by flange 8, sparge pipe is made up of two semicircle water pipes that have nozzle 4, in the intermittent time of perforation, to the top water spray, realize the cooling of top from all around.Come directly towards cooled waste water and enter sluice by the adjutage 6 that is installed in water tank bottom, tank upper cover has cover plate 7.
The course of work of this device is: after perforation finished, the mandril anti-thrust trolley band push rod, 9 extract from hollow billet 10 top, move to take off pipe unit before, take off pipe die 5 and the hollow billet head is blocked make the hollow billet location, allow top, push rod to extract out by die orifice.The top just enters cooling water tank 1 after die orifice is extracted out, the interior sparge pipe 2 of water tank, is realized coming directly towards and cooled off to the top water spray from all around.
