Abstract
The utility model relates to a hard alloy bushing roller for a roller drawing die, belonging to the field of metal processing, in particular to the hard alloy bushing roller for the roller drawing die, which is used for processing spring steel wires with various special section shapes. The hard alloy bushing roller for the roller drawing die is composed of a hard alloy roller and a bearing steel sleeve, wherein the bearing steel sleeve is inlaid on an inner hole of the hard alloy roller, and the bearing steel sleeve subjected to heat treatment is inlaid onto the hard alloy roller with a direct extrusion method. After the hard alloy roller with the bearing steel sleeve is directly contacted with a needle bearing, the service life of the hard alloy roller is greatly prolonged, and the production efficiency of the hard alloy roller is greatly increased. The hard alloy bushing roller for the roller drawing die has the advantages of simple structure, long service life and high production efficiency.
Description
Technical field
A kind of roller drawing-die of the utility model belongs to the metal manufacture field with the carbide alloy bushing roll, particularly relates to a kind of a kind of roller drawing-die carbide alloy bushing roll of processing various cross sectional shape heterotypic spring steel wires.
Background technology
The roller drawing-die is a kind of equipment that is mainly used in processing various cross sectional shape heterotypic spring steel wires, and it is to adopt hard alloy roll, needle bearing and roller bearing jointly to assemble use.The hardness (HRC approximately 58～61) that is higher than needle bearing because of the hardness (HRC 〉=65～69) of hard alloy roll, when producing various cross sections heterotypic spring steel wire, needle bearing is easy to occur wear out failure than the larger stress of hard alloy roll carrying, has seriously limited production efficiency.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of long service life, a kind of roller drawing-die carbide alloy bushing roll that production efficiency is high.
The purpose of this utility model reaches by following measures, a kind of roller drawing-die is comprised of hard alloy roll and bearing steel sleeve with the carbide alloy bushing roll, embedded bearing steel bushing on the hard alloy roll endoporus, direct extrusion is embedded in bearing steel sleeve after heat treatment on the hard alloy roll, greatly improves with service life and production efficiency after needle bearing directly contacts with the hard alloy roll of bearing steel sleeve.
Bearing steel sleeve thickness 1.0～3.0mm of the present utility model.
Of the present utility model simple in structure, long service life, production efficiency is high.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is accompanying drawing 1 side schematic views.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: hard alloy roll 1, bearing steel sleeve 2.
As shown in Figure 1, a kind of roller drawing-die of the utility model is comprised of hard alloy roll 1 and bearing steel sleeve 2 with the carbide alloy bushing roll, embedded bearing steel bushing on the hard alloy roll endoporus, bearing steel sleeve thickness 1.0～3.0mm, it is with direct extrusion after heat treatment bearing steel sleeve to be embedded on the hard alloy roll, with the hard alloy roll of bearing steel inner sleeve with after needle bearing directly contacts service life more traditional assembling mode production efficiency greatly improve.
Claims (2)
1. a roller drawing-die carbide alloy bushing roll is characterized in that being comprised of hard alloy roll and bearing steel sleeve embedded bearing steel bushing on the hard alloy roll endoporus.
2. a kind of roller drawing-die carbide alloy bushing roll according to claim 1 is characterized in that bearing steel sleeve thickness 1.0～3.0mm.
