Description
Technical Field
The utility model relates to a machine tooling cooling technology field specifically is a punch top outer water cooling device.
Background
The hot-rolled seamless steel pipe is rolled by a piercer, and the basic process of piercing and rolling comprises the following steps: the roller, guide plate and top head are formed into a closed hole pattern, and the high-temperature metal can be continuously deformed in the region formed by said hole pattern, and finally the hollow pipe blank can be rolled out from the solid pipe blank. The roller and the guide plate are relatively fixedly installed according to the technological requirements, the ejector head is installed on the ejector rod of the ejector rod trolley, and the rolling position and the post-working position are periodically alternated along with the action requirement of the rolling period. As the solid tube blank is punched into the hollow tube blank, the metal deformation is mainly concentrated on the top head; meanwhile, the ejector head works at high temperature and high pressure, so that the ejector head is easy to wear or the nose part is pressed and piled, the ejector head cannot be used for a long time, the ejector head is frequently replaced, and the ejector head needs to be cooled by water during working.
At present, the plug cooling mode of the male piercing mill generally adopts an internal cooling mode, namely, from an interface point at the tail part of the piercing mill, low-temperature high-pressure water is conveyed through a long rubber pipe and connected to the tail part of a mandril trolley, flows through the inside of a central pipe in the mandril after passing through the inside of the mandril trolley and is conveyed to the inside of the plug of the piercing mill, and the cooling is realized from the inside of the plug of the piercing mill. The cooling mode can only cool the inside of the plug, the external cooling is slow, the temperature difference inside and outside the plug is large, the cooling effect is good, and the service life of the plug is influenced.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned defect and not enough, the utility model provides a punch top outer water cooling device can just accelerate the cooling rate of top surface, reduces the inside and outside difference in temperature of top, extension top life practices thrift the cost in business.
In order to realize the technical task, the utility model discloses a following technical scheme realizes:
the utility model provides an outer water cooling device of perforator top, includes coolant tank, inlet tube and condenser tube, the inlet tube pass through the reducing three-way valve respectively with two parallelly connected condenser tube connection, coolant tank's upper end is equipped with the pipe support ring, condenser tube is vertical the both sides of fixing at the pipe support ring respectively, condenser tube end connection has the shower nozzle, the axis of the directional pipe support ring of shower nozzle.
Each cooling water pipe is provided with at least one spray head.
The spray head is a universal spray head.
The cooling water pipe is a stainless steel pipe.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a pair of outer water cooling device of punch top directly cools off the surface of top for the cooling rate of top surface, the internal cooling of cooperation top can reduce the inside and outside difference in temperature of top, extension top life practices thrift the cost in business.

FIG. 2 is a left side view of the water cooling device outside the plug of the piercing machine.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.
As shown in fig. 1-2: the utility model provides a perforating machine top extra water cooling device, includes coolant tank 1, inlet tube 2 and condenser tube 3, and inlet tube 2 is connected with two parallelly connected condenser tube 3 respectively through reducing three-way valve 4, is equipped with pipe support ring 5 in coolant tank 1's upper end, guarantees the perforation in-process, and the axis of steel pipe blank is unchangeable to and provide support to the steel pipe blank. Two cooling water pipes 3 are vertically fixed on two sides of the pipe supporting ring 5 respectively, the end parts of the cooling water pipes 3 are connected with spray heads 6, and the spray heads 6 point to the axis of the pipe supporting ring 5 to ensure that all sprayed cooling water points to the top head 7. The cooling water is sprayed to the outer surface of the plug 7 from the spray head 6, and the cooling device inside the plug 7 is matched, so that the temperature difference inside and outside the plug can be reduced, the service life of the plug is prolonged, and the enterprise cost is saved.
Each cooling water pipe 3 has at least one spray head 6, and in order to improve the cooling effect and the cooling speed, two or three spray heads 6 can be arranged on each cooling water pipe 3.
The spray head 6 is a universal spray head, and the spraying direction of the cooling water is convenient to adjust.
The cooling water pipe 3 is made of stainless steel pipes, so that rusting is prevented, and the service life is prolonged.
The utility model provides a pair of outer water cooling device of punch top directly cools off the surface of top for the cooling rate of top surface, the internal cooling of cooperation top can reduce the inside and outside difference in temperature of top, extension top life practices thrift the cost in business.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
