Description

Technical Field

[0001] The utility model relates to the field of mold manufacturing, in particular to a mold manufacturing hole expanding device. Background Art

[0002] A radial drilling machine is a drilling machine with a rocker arm that can rotate and rise and fall around a column. Usually, the spindle box moves horizontally on the rocker arm. When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces. The radial drilling machine can align the tool by moving the tool axis position, which greatly facilitates the machining of holes on large and heavy workpieces in single-piece and small-batch production.

[0003] The existing patent, application number 02120792483.9, discloses a radial drill reaming device for mold manufacturing, comprising a base, the upper sidewall of which is fixedly connected to a straight rod and a workbench, a sleeve provided on the outer sidewall of the straight rod, one side outer wall of which is connected to a limiting slide via a square block, the limiting slide being connected to a motor via a matching slider, and the output shaft of the motor being fixedly connected to a drill bit, a first rotating block provided on the outer wall of the limiting slide away from the square block, and a first rotating rod fixedly connected to one side wall of the first rotating block. By coordinating multiple groups of structures, the horizontal position and height of the drill bit can be changed more easily, which also makes it easier to use the radial drill bit for reaming operations.

[0004] However, this patent still has the following problems in actual use: the reaming device cannot rotate, and can only align the mold to be reamed with the beam on which the drill bit is installed up and down. At the same time, it is not convenient to align the drill bit with the hole in the mold, resulting in a lot of time being wasted on calibrating the position of the mold and the beam and the position between the drill bit and the hole before reaming, which greatly reduces work efficiency.
