Line polishing machine used for wire-drawing die

Abstract

The invention belongs to the technical field of wire-drawing die polishing machining, and particularly relates to a line polishing machine used for a wire-drawing die. The line polishing machine used for the wire-drawing die comprises a rack, a positioning die holder, a rotating driving module and a deflection adjusting module; the deflection adjusting module comprises a crankshaft, a deflection power source and an eccentric adjusting plate, an eccentric hole is formed in the eccentric adjusting plate in a penetrating mode so that an eccentric section of the crankshaft can be sleeved with the eccentric adjusting plate in a hooped mode, and the eccentric adjusting plate is sleeved with a fixing ring; the outer wall of the fixing ring extends outwards in the radial direction to form a deflection rod, and an extending end of the deflection rod is eccentrically hinged to a rotating shaft; the deflection adjusting module further comprises an outer adjusting sleeve; and a radial adjusting groove is formed in the outer plate face of the eccentric adjusting plate, a guide sliding block is arranged on the inner end face of the outer adjusting sleeve, and the guide sliding block and the radial adjusting groove form a sliding rail guide fit relation. According to the line polishing machine used for the wire-drawing die, an angle between the axis of the wire-drawing die and the axis of a tool metal wire can be adjusted continuously, conveniently and reliably, and finally, the purpose of wire-drawing die inner hole machining with high efficiency, high quality and convenience is achieved.

Description

technical field [0001] The invention belongs to the technical field of polishing processing of wire drawing dies, and in particular relates to a wire polishing machine for wire drawing dies. Background technique [0002] The wire drawing die is a pressure drawing treatment die based on the wire, which can make the wire blank undergo plastic deformation through the die hole under a certain tensile force, so as to achieve the purpose of reducing its cross section and increasing its length; among them, Due to the use of natural diamonds or artificial diamonds as raw materials, diamond drawing dies have strong wear resistance and long service life, and are widely used. The conical compression working area and the cylindrical sizing area of ​​the inner hole of the diamond wire drawing die must have a certain hole shape accuracy and a high degree of smoothness. In order to process the tapered and cylindrical shapes with precise dimensions and high smoothness at the inner hole of ...

Problems solved by technology

The defect of the above-mentioned existing structure is that the angle deflection between the axis of the drawing die and the axis of the tool wire is currently fixed and adjusted, that is, the drawing die is adjusted to a certain angle and then fixed, and then adjusted each time according to the needs. It is obvious that the adjustment is cumbersome and time-consuming, the amount of repetitive labor is large, and there are unavoidable adjustment errors.

In addition, the above-mentioned fixed-angle adjustment method that needs to be st
