Description

Adjustable roller die pulling device

Technical Field

The application relates to the technical field of mechanical preparation, in particular to an adjustable roller die drawing device.

Background

Roller die drawing is a metal working technique combining rolling and cold drawing. The metal is plastically deformed by applying a traction force through the passive roll die holes. The number of rollers forming the die holes can be divided into two rollers, three rollers and the like, the rollers forming each die hole form a module, and the roller die device is generally formed by connecting a plurality of modules and can be divided into a two-connection type, a three-connection type, a four-connection type and the like. The material is substantially changed into rolling friction of a bearing with good lubrication during drawing of the fixed mould, so that drawing friction is greatly reduced. Compared with the traditional fixed die drawing, the roller die drawing has the advantages of small drawing force, uniform deformation, high pass compression ratio, small damage to the grinding tool, high production efficiency, energy conservation, environmental protection and the like.

For the rectangular small-section bar, the preparation process is mostly rolling, fixed die drawing and two-connected two-roller die drawing, but the traditional process is mostly characterized by complex equipment manufacture, large drawing force, complex drawing and annealing pass and the like, and consumes a great amount of manpower and material resources.

Compared with the traditional process for preparing the rectangular small-section profile by using the four-roller die, rolling friction is generated between the material and the roller die, the contact friction resistance of deformed metal is smaller, the axial compressive stress is larger, and the plastic flow capacity of the metal is fully improved. In addition, the lower friction resistance reduces the energy consumption, and can realize high-speed diameter reduction and reduce the drawing force when drawing deformation.

However, at present, the research on four-roller die drawing is mostly in the aspects of process and hole pattern design, few patent researches on the design of complete roller die equipment are provided, the practical verification of four-roller die drawing is less, and no relatively systematic research on adjustable equipment for realizing four-roller die drawing of rectangular small-section sectional materials is provided. And the traditional four-roller die drawing device is complicated in adjusting the size of the roller gap, has a plurality of restrictions on the types of drawn workpieces and is not strong in device stability.
