Description

Technical Field

[0001] The invention relates to the technical field of thick foil shears, in particular to a tool changing mechanism for a tool holder tailstock specially used for thick foil shears. Background Art

[0002] The thick foil shear is the main equipment for longitudinal cutting of steel and non-ferrous metal foil rolls. Its main function is to cut the rolled metal foil rolls into materials of specified width according to the needs. It is generally used with the assistance of a special tool holder tailstock tool changing mechanism. The traditional tool holder tailstock tool changing mechanism for thick foil shears fixes the rotating blade shaft by direct socket connection, which is very easy to cause the rotating blade shaft to shake and fall off during use, which is not conducive to the accuracy of shearing. At the same time, it is troublesome to install and disassemble, which is not conducive to the user to replace the butterfly blade of the rotating blade shaft. At the same time, the traditional tool holder tailstock tool changing mechanism for thick foil shears is very easy to rub against the edge of the rotating blade shaft during use, causing the rotating blade shaft to wear, which is not conducive to user use. In addition, there is no protective device, and external impact is very easy to cause the rotating blade shaft to be damaged, reducing the service life of the rotating blade shaft. In view of these defects, it is very necessary to design a tool holder tailstock tool changing mechanism for thick foil shears. Summary of the invention
