Problems solved by technology

For copper pipes that need to be bent in different directions multiple times, using the existing bending machine 000' will make the entire bending process too cumbersome, time-consuming, and the quality of the bending cannot be effectively guaranteed. In addition, the entire bending The structure of the shape machine 000' is also too complicated, with a lot of space interference
[0005] In addition, copper pipes with different pipe diame

Abstract

The invention discloses a numerical control multi-position die changing mechanism, which comprises a headstock and a headstock rotating mechanism used for driving the headstock to rotate at a set angle; a rotating shaft axis, a driving gear, a driving unit, a driving oil cylinder and a tapered wedge are arranged in the headstock, wherein the driving gear is superposed with a rotating shaft of the headstock, the driving unit is used for driving the driving gear to rotate, a piston rod of the driving oil cylinder is superposed with the rotating shaft of the headstock, and the tapered wedge is connected with the tail end of the piston rod of the driving oil cylinder; the numerical control multi-position die changing mechanism also comprises multiple groups of R die assemblies annularly distributed around the rotating shaft axis of the headstock; each R die assembly comprises an upper die, a lower die, an R die mounting base, a bearing, a bearing mounting base, a driven gear and a double-section pull rod, wherein the bearing is used for driving the R die mounting base to rotate, the bearing mounting base is used for connecting the headstock with the bearing, a rotating shaft axis of the driven gear is perpendicular to the rotating shaft of the headstock, and the double-section pull rod extends along a direction perpendicular to the rotating shaft of the headstock to the interior of the headstock.

Description

technical field [0001] The invention relates to the technical field of pipe bending equipment, in particular to a numerically controlled multi-position die changing mechanism. Background technique [0002] In the refrigeration industry, refrigeration copper tubes are a common refrigeration accessory, mainly used for the circulation of refrigerant; Installation arrangement. When the existing copper pipe is bent, it is generally bent by a bending machine with a steering mechanism for turning the copper pipe and can only be bent in one direction, and The bending radius generally does not exceed two. If it is necessary to bend pipes in different directions and different bending radii in succession, it is necessary to replace different bending machines several times. [0003] See attached figure 1 Shown is a schematic structural view of the existing one-way bending machine 000' (where the steering mechanism on the existing one-way bending machine is not shown), the existing o...
