Abstract
The utility model discloses a prevent that roll from gluing copper spray set, its technical scheme main points are: the roll head spraying device comprises a water spraying ring, wherein a plurality of spraying holes are uniformly distributed on one side of the water spraying ring facing a roll head, and the spraying holes are arranged in a concentric circle shape; the spray holes are provided with a certain opening angle, so that the water spraying direction is inclined towards the rolling center. The cooling position of the roller is more reasonably designed in the rolling process, and the cooling is more uniform; the surface of a rolling area of the roller is smooth and clean, and the service cycle is long; the rolled tube has stable quality, high surface smoothness, high precision and high yield; the production efficiency of the equipment is high, and the processing cost is low.
Description
Technical Field
The utility model relates to a three-roller planetary rolling mill, especially a spray set who prevents that roll from gluing copper suitable for use on three-roller planetary rolling mill.
Background
The three-roller planetary rolling mill rolls the copper pipe blank with the diameter of 90 mm into a copper pipe with the diameter of about 40 mm, the copper pipe is strongly deformed, high temperature of 650-700 ℃ can be generated, and besides good materials are required to be adopted by the equipment, good cooling conditions are required to be provided for ensuring uniform cooling of the roller. The device for cooling and preventing copper adhesion in the process of rolling the copper pipe by the three-roller planetary rolling mill adopts a single-row-hole spraying type stainless steel hollow ring sleeve, a water spraying ring is arranged at a certain distance from a roller head, water flow is parallel to the rolling center in the horizontal direction, and the water spraying direction faces to the rolling position of three rollers; the distance between the water spray ring and the roller head is far, and the included angle formed by the water spray holes and the axial direction is 0 degree.
The structure causes unreasonable water spraying position design, deviation and unevenness of cooling of the rolling area of the roller, copper is easy to adhere to the surface of the rolling area of the roller, the surface of the rolling area of the roller becomes rough, and the following adverse effects are caused: the service life of the roller is reduced; the surface of the rolled pipe is rough, the precision is low, and the rolled pipe is scrapped in batches;
the roller is frequently replaced, the production efficiency is reduced, and the production cost is increased.
Disclosure of Invention
The utility model aims at designing a rational in infrastructure, can effectively improve roll life's prevent that the roll from gluing copper spray set.
The technical scheme of the utility model, a prevent that roll from gluing spray set of copper, it includes the water spray ring, its characterized in that: a plurality of spray holes are uniformly distributed on one side of the water spray ring facing the roller head, and the spray holes are arranged in a concentric circle shape; the spray holes are provided with a certain opening angle, so that the water spraying direction is inclined towards the rolling center.
The arrangement of the spray holes is in concentric circle shape, so that the number of the spray holes can be increased.
The opening angle of the spray holes is 10-14 degrees from the water spraying direction to the rolling center.
The spray ring is located closer to the roller head, at a distance of 30 mm.
The utility model has the advantages that: the cooling position of the roller is more reasonable in the rolling process, and the cooling is more uniform; the surface of a rolling area of the roller is smooth and clean, and the service cycle is long; the rolled tube has stable quality, high surface smoothness, high precision and high yield; the production efficiency of the equipment is high, and the processing cost is low.
Drawings
Figure 1 is a using state diagram of the utility model,
fig. 2 is a cross-sectional view of the present invention.
The specific implementation mode is as follows:
the embodiments are described in detail in connection with the above drawings,
a spray device for preventing a roller from being adhered with copper comprises a spray ring 1, wherein a plurality of spray holes 2 are uniformly distributed on one side of the spray ring facing a roller head, and the spray holes are arranged in a concentric circle shape; the spray holes are provided with a certain opening angle, so that the water spraying direction is inclined towards the rolling center;
the arrangement of the spray holes is in concentric circle shape, so that the number of the spray holes can be increased.
The annular compaction tool is structurally characterized in that: the opening angle of the spray hole is 10-14 degrees from the water spraying direction to the rolling center;
the spray ring is located closer to the roller head, at a distance of 30 mm.
The utility model discloses utilize the width of the ring body of spray ring, further expanded the quantity of arranging of hole for water spraying, simultaneously more reasonable design the water spray angle of hole for water spraying, can be better satisfy the cooling to the roll at rolling in-process.
The above examples are merely illustrative for clarity and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not necessary or necessary to exhaustively enumerate all embodiments herein, and obvious variations or modifications can be made without departing from the scope of the invention.
Claims (3)
