Problems solved by technology

[0003] The circular die is a standard tool for processing and trimming external threads. The traditional circular die can only process the outer cylinder of the workpiece with a certain fixed value, and cannot process the external thread for the outer cylinder of the workpiece with different diameters.

Abstract

The invention relates to the technical field of circular dies, in particular to an adjustable circular die. The adjustable circular die comprises a circular die body, a fixing frame and first adjusting bolts, the circular die body is formed by splicing four arc-shaped circular die components, mounting holes are formed in the middle of the circular die body, chip removal holes are formed in the middles of the arc-shaped circular die components, adjustable threading die tapping bodies are arranged on the two sides of the chip removal holes, the fixing frame is of a square structure, and each arc-shaped circular die component is arranged on a frame edge of the fixing frame through the corresponding first adjusting bolt. The arc-shaped circular die components can be adjusted to adapt to a to-be-machined part through the first adjusting bolts, threads are machined on the to-be-machined part, generated waste is discharged into the chip removal holes, and therefore tapping efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of circular dies, in particular to an adjustable circular die. Background technique [0002] The die is equivalent to a nut with high hardness. There are several chip removal holes around the screw hole. Generally, cutting cones are ground at both ends of the screw hole. Dies are divided into round dies, square dies, hexagonal dies and tubular dies according to their shapes and uses. Among them, the circular die is the most widely used. When the pitch diameter of the processed thread exceeds the tolerance, the adjustment groove on the die can be cut to adjust the pitch diameter of the thread. The precision of the thread processed by the die is low, but due to its simple structure and convenient use, the die is still widely used in single-piece, small-batch production and repair. [0003] The circular die is a standard tool for processing and trimming external threads. The traditional circular die can only ...
