Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trimming device for cutting burrs formed on the outer periphery of an object to be machined, and more particularly to a trimming device arranged on a manufacturing line for continuously trimming a plurality of objects to be machined. .

[0002]

2. Description of the Related Art Conventionally, a trimming device for cutting off burrs formed on a pressed part, a cast part or the like has been used. For example, in Japanese Patent Laid-Open No. 10-328750, a trimming mold is used as a lower mold of a screw press device. Wear 1
Disclosed is a work deburring method and device in a screw press, which is capable of consistently performing all the processes from pressing of a forming material and deburring of the processed product in a pressing step. According to this publication, the molding material is sandwiched between a lower mold and an upper mold to be molded, and then the deburring of the processed product is continuously performed by a trimming mold.

[0003]

In the conventional trimming apparatus, which includes the apparatus proposed in the above publication, a die is used, and a dedicated die suitable for the object to be processed is used. Therefore, when the outer diameter of the processing target is different, it is necessary to prepare a mold suitable for the outer diameter of the processing target and replace it. However, preparing multiple molds not only increases the cost, but also
This is a factor that increases the manufacturing time and the manufacturing cost for securing storage space, exchanging molds, etc. In particular, in the case where a large number of products are manufactured in a small amount as in recent years, the time required for the mold replacement process leads to a large increase in manufacturing cost. On the other hand, although improving the die is one method, it is still not easy to attach and detach the object to be machined to the die, and it is not possible to continuously trim a plurality of objects to be machined on the manufacturing line.

Therefore, an object of the present invention is to provide a trimming device capable of continuously trimming the outer periphery of a processing target on a manufacturing line without using a die.
