Abstract
The utility model discloses a hot rolling round steel wire rod, including the round steel wire rod of wire rod shape, the round steel wire rod is formed by carbon steel material hot rolling, its characterized in that: the round steel wire rod is provided with an annular shrink every fixed length distance, and the annular shrink forms a necking groove on the surface of the outer circle of the round steel wire rod. The utility model discloses can make the coefficient of surface friction little after bonderizing, make things convenient for the cold-heading shaping of shaft class part, improve the mould life-span.
Description
Technical Field
The utility model relates to a hot rolling round steel wire rod.
Background
The hot-rolled round steel wire rod is generally a metal wire rod with a diameter of 5-22mm, and is also commonly called a wire rod because the wire rod is delivered in a wire rod form, and the hot-rolled round steel wire rod is generally made of common carbon steel and high-quality carbon steel. At present, the hot rolling round steel wire rod of thick diameter is used for the cold-heading preparation of axostylus axostyle class part in a large number, before the cold-heading preparation, the hot rolling round steel wire rod is whole earlier to be rolled up and is carried out the surface phosphating, the coefficient of surface friction who makes it is little, however, when the cold-heading preparation, because the hot rolling round steel wire rod at first will be cut off by fixed length, cut off the port and do not have the bonderizing layer to cover, so the outer fringe that cuts off the port at the cold-heading in-process is turned up easily and is produced great friction with the cold-heading mould inner chamber, the cold-heading power is big, easily.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a hot rolling round steel wire rod that can make coefficient of surface friction little after phosphating treatment makes things convenient for the cold-heading shaping of shaft class part, improves the mould life-span is provided.
Therefore, the utility model discloses an adopt following scheme to realize:
hot rolling round steel wire rod, including the round steel wire rod of wire rod shape, the round steel wire rod is formed by carbon steel material hot rolling, its characterized in that: the round steel wire rod is provided with an annular shrink every fixed length distance, and the annular shrink forms a necking groove on the surface of the outer circle of the round steel wire rod.
Above-mentioned technical scheme's hot rolling round steel wire rod, at first according to the line footpath of the axostylus axostyle class part design round steel wire rod of waiting cold-heading and the fixed length distance that sets up the necking down groove, then carry out the hot rolling customization of round steel wire rod, next before the cold-heading preparation, round steel wire rod is whole earlier to be rolled up and is carried out surface phosphating treatment, the coefficient of surface friction who makes it is little, afterwards when the cold-heading preparation, round steel wire rod is cut off by the fixed length, it is located the necking down groove position to cut off the port position, so, though it does not have the bonderizing layer to cover to cut off the port, nevertheless because the outer fringe that cuts off the port is less than the wire rod external diameter, so the outer fringe that cuts off the port in the cold-heading in-process just can not produce the evagination, avoid producing contact.
Preferably, the cross section of the necking groove is in a circular arc shape or a V shape with a circular arc at the groove bottom.
Preferably, the wire diameter of the round steel wire rod is 15-22mm, and the groove depth of the necking groove is 10-15 percent of the wire diameter.
Drawings
The utility model discloses there is following figure:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in the figure, the utility model discloses a hot rolling round steel wire rod, round steel wire rod 1 including the wire rod shape, round steel wire rod 1 is formed by carbon steel material hot rolling, and the line footpath of round steel wire rod 1 is 15-22mm, and round steel wire rod 1 is equipped with an annular shrink every fixed length distance, and this annular shrink can be when the round steel wire rod still does not cool off after the hot rolling, export through the punching press formation at the hot rolling mould, and this annular shrink forms throat groove 2 on the excircle surface of round steel wire rod, and the shape of cross section of throat groove 2 is convex or the V-arrangement of tank bottom area circular arc, and the groove depth of throat groove 2 is 10 to percent 15 of line footpath.
Claims (3)
1. Hot rolling round steel wire rod, including the round steel wire rod of wire rod shape, the round steel wire rod is formed by carbon steel material hot rolling, its characterized in that: the round steel wire rod is provided with an annular shrink every fixed length distance, and the annular shrink forms a necking groove on the surface of the outer circle of the round steel wire rod.
2. The hot rolled round steel wire rod of claim 1, wherein: the cross section of the necking groove is in a circular arc shape or a V-shaped shape with a circular arc at the groove bottom.
