Single screw rod type blanking machine driven by alternating-current servo motor and asynchronous motor in hybrid way

Abstract

The invention discloses a single screw rod type blanking machine driven by an alternating-current servo motor and an asynchronous motor in a hybrid way. The single screw rod type blanking machine comprises a driving mechanism, a moving die blanking mechanism and a static die blanking mechanism. By utilizing the design of performing high-speed blanking in the way of the linear motion of a ball screw rod and the design way that a moving die and a static die move relatively, a radial load can be conveniently loaded onto a bar pipe material; due to an accurate die positioning design, the blanking process is simple and practical; a blanking die can be replaced according to different process requirements; the precise blanking can be carried out aiming at the bar pipe materials made of different materials and having different diameters; and the single screw rod type blanking machine has the advantages of compact structure, high efficiency, low energy consumption, practicability, convenience and the like.

Description

technical field [0001] The invention relates to the technical field of blanking machines, in particular to a single-screw type blanking machine driven by an AC servo and an asynchronous motor. Background technique [0002] The blanking of metal bars widely exists in the preparation process of cold extrusion, die forging, metal chain pins, rolling bearing rollers, pin standard parts and shaft parts, and in these blanking processes, the amount of blanking is huge, For example, the hometown of chains in Jinhua, Zhejiang Province can produce metal chains with a length of hundreds of millions of meters every year, and Beijing Needle Roller Bearing Factory needs tens of millions of needle rollers every year. However, the current traditional shearing, sawing, high-energy cutting and other blanking methods have problems such as low material utilization rate, large blanking force, low production efficiency, high energy consumption, and poor section quality, which do not meet the requ...

Require

[0003] The traditional blanking methods include lathe cutting and sawing. Although these two blanking methods can obtain a flat section, they have disadvantages such as low production efficiency and waste of raw materials.

For this reason, in the subsequent industrial production, punching machines or special bar shears were widely used for shearing and blanking. However, the common shearing and blanking method has large blanking force, high energy consumption, and the section of the bar is obviously In order to meet the requirements of the next process such as cold extrusion, it is necessary to arrange a process of turning and flattening the section after ordinary shearing and blanking, which reduces production efficiency, wastes materials and increases production costs.
