Opposite-cutting type blanking machine for driving linear motion of double screw rods by AC (Alternating Current) servo motor

Abstract

The invention relates to an opposite-cutting type blanking machine for driving linear motion of double screw rods by an AC (Alternating Current) servo motor, which comprises a driving mechanism, a blanking radially-loading blanking mechanism and a feeding radially-loading blanking mechanism. The linear motion mode of a ball screw can be utilized to carry out the design of high speed blanking, the linear motion speed of the molds can be improved by the design of the inverse motion of two sets of movable molds, and the blanking process is simple and practical by the design of the instant, rapid motion and the rapid and accurate returning of the molds; the blanking molds can be replaced according to the different process requirements; and rod pipe materials can be preciously discharged by aiming at different materials and different diameters. The opposite-cutting type blanking machine has the advantages of compact structure, high efficiency, low energy consumption and the like and is practical and convenient.

Description

technical field [0001] The invention relates to the technical field of cutting machines, in particular to an alternating-current servo motor-driven double-screw linear motion split-cutting type cutting machine. 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...

Problems solved by technology

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 requirements of green manufacturing. 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.
