Description

Technical field

[0001] The utility model relates to the technical field of machining, in particular to a directional blanking device which cooperates with a milling machine tool to assist in blanking after cutting a workpiece. [Background Technology]

[0002] Currently, most hardware processing is performed using fully or semi-automatic machine tools, such as lathes, milling machines, or CNC machining. These tools place high demands on the precision of the finished product, with extremely precise tolerances. Control valves, in particular, require not only precise dimensional accuracy but also stringent, even extreme, surface finish and flatness requirements. This necessitates adherence to process specifications and protective measures throughout the entire processing and quality inspection process, including those designed to prevent slip marks, bumps, and collisions.

[0003] When machining shafts and sleeves on existing lathes and milling machines, where parts are directly cut from the workpiece using a turning or milling cutter, the conventional method for receiving the material is to place a chute beneath the turning or milling cutter, allowing the cut workpiece to flow down the chute onto a receiving tray. This method is straightforward and simple for products with high hardness or low surface roughness requirements, as the product simply rolls onto the receiving tray. Furthermore, the intermediate links are stacked in a disorderly manner, so occasional collisions are not a problem.

[0004] However, if the outer surface of control valve products has extremely high requirements for smoothness and finish, such material receiving and flow conveying methods cannot meet the requirements. In view of the above actual work needs, it is necessary to design equipment that can cooperate with processing machine tools to gently receive and unload materials and ensure that there is no collision. [Summary of the invention]
