Description

High-precision trimming die

Technical Field

The utility model relates to a high accuracy cut off die belongs to cut off die technical field.

Background

At present, the trimming die is widely used in the fields of mechanical manufacturing, automobile part production, beverage bottle processing, fastener die matching and the like, and the most commonly used trimming die is a hexagonal trimming die, so the smoothness of the section of a workpiece is directly influenced by the trimming precision of the trimming die; however, since some small-sized parts have small hexagonal holes, the machining difficulty is high, the manufacturing cost is high, and especially for some small enterprises lacking a compact numerical control machine tool, the trimming die meeting the precision required by customers cannot be smoothly manufactured, so that a high-precision trimming die with low machining cost and high precision is needed.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a low and high accuracy cut off die that can utilize lathe to improve machining precision of processing cost.

The purpose of the utility model is realized like this:

the utility model provides a high accuracy cut-off die, high accuracy cut-off die includes to closing left semi-ring and the right semi-ring that constitutes a complete annular structure, be provided with locating hole one and reference column two on two upper and lower involution faces of left side semi-ring respectively, be provided with reference column one and locating hole on two upper and lower involution faces of right semi-ring respectively, and reference column one inserts and arranges in locating hole one, and reference column two inserts and arranges in the locating hole, all be provided with the screw on the involution face of left semi-ring and right semi-ring, fastening bolt arranges in the screw of left semi-ring and right semi-ring soon and realizes the connection to left semi-ring and right semi-ring.

The utility model relates to a high accuracy cut off die, all write personally on the cut off face of left side semi-ring and right semi-ring and be provided with domaticly, and the open end of the screw on left side semi-ring or the right semi-ring all is located domaticly.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses be split type structure with the design of cut off die to be convenient for utilize conventional lathe to polish processing to both sides and side cut, then the equipment uses, consequently very big reduction the manufacturing cost of cut off die, and can make things convenient for the precision that middle and small enterprises utilized common lathe to process it and make, make it can obtain more extensive popularization.
