Diamond wire-drawing die

Abstract

The invention relates to the technical field of wire drawing dies, in particular to a diamond wire drawing die, which can draw metal wires of various shapes, improve adaptability, and reduce use limitations; The extrusion force of the circular steel sleeve is relatively protected, which is beneficial to long-term use; it includes the mold core and the circular steel sleeve, and the inner hole of the mold core has a bell mouth, an inlet cone, a deformation cone, a sizing belt and an outlet angle; It also includes two sets of fixing blocks, two sets of connecting blocks, two sets of first fixing springs, two sets of second fixing springs and two sets of pushing blocks. Fixing grooves are arranged on the front half area and the back half area of ​​the left end of the mold core. The blocks are respectively set in two sets of fixing slots, the left ends of the two sets of inserting blocks are provided with second slots, and the right ends of the two sets of pushing blocks are respectively inserted into the two sets of second slots; two sets of buffer spring sets and two sets of half Ring-shaped buffer plates, two sets of semi-annular buffer plates are respectively arranged on the output ends of the two sets of buffer springs.

Description

technical field [0001] The invention relates to the technical field of wire drawing dies, in particular to a diamond wire drawing die. Background technique [0002] As we all know, a diamond wire drawing die is an auxiliary tool for drawing various metal wires, which is widely used in the field of production and processing; the existing diamond wire drawing die includes a core and a circular steel sleeve, and the core is tightly It is embedded in a circular steel sleeve, and there are bell mouth, entrance cone, deformation cone, sizing belt and exit angle in the inner hole of the core; when this diamond wire drawing die is used, only the circular steel sleeve needs to be fixed on the wire drawing equipment Then, the metal can be drawn through the core; in the use of this diamond wire drawing die, it is found that the shape and size of the finished wire drawing are related to the shape of the core. This tool can only pull out a metal wire of one shape, and the adaptability is...

[0002] As we all know, a diamond wire drawing die is an auxiliary tool for drawing various metal wires, which is widely used in the field of production and processing; the existing diamond wire drawing die includes a core and a circular steel sleeve, and the core is tightly It is embedded in a circular steel sleeve, and there are bell mouth, entrance cone, deformation cone, sizing belt and exit angle in the inner hole of the core; when this diamond wire drawing die is used, only the circular steel sleeve needs to be fixed on the wire drawing equipment Then, the metal can be drawn through the core; in the use of this diamond wire drawing die, it is found that the shape and size of the finished wire drawing are related to the shape of the core. This tool can only pull out a metal wire of one shape, and the adaptability is poor Poor, high use limitations; and the extrusion force of the wire drawing equipment on the circular steel sleeve is relatively large, resulting in the circular steel sleeve being easily broken, which is not conducive to long-term use
