High-accuracy numerical control eight-axle helical compression spring former

Abstract

The invention provides a high-accuracy numerical control eight-axle helical compression spring former. The former comprises a machine tool body, an alignment mechanism, a press feeding mechanism, an upper reducing mechanism, a pitch mechanism, a mandril, a middle reducing mechanism, a lower reducing mechanism, a computer control box, an upper cut mechanism and a lower cut mechanism. The former isdesigned by combining machinery, the computer closed ring technology and pneumatic technology, the whole machine tool realizes intelligent operation, and eight-axle data control is realized, so that the performance and reliability of the former are improved along with high sensitivity, quick response and accurate dimension accuracy, the manual operation amount is reduced, the working efficiency is improved, the operation is safe and convenient, and energy consumption is saved. In the former, 'mandril-cut' integration is realize to ensure that no tail hook exists in cutting, and a three-axle design is adopted for the reducing mechanism to ensure that the product has high processing accuracy, and the product quality and production efficiency are improved.

Description

technical field [0001] The invention relates to a spring processing mechanical equipment, in particular to a high-precision numerical control eight-axis spiral compression spring forming machine. Background technique [0002] In industries such as machinery, automobiles, tractors, and electrical appliances, springs, as one of the most basic mechanical parts, especially coil springs used for balance mechanisms in machinery, are widely used in various fields of national economy and social life. Therefore: Higher technical requirements are put forward for the mechanical equipment for processing springs. In the past, most of the equipment for processing springs was a purely mechanical spring coiling machine, with complex structure, single function, cumbersome debugging, and low processing accuracy. In order to improve production efficiency, many factories used single-chip microcomputers to control the forming of springs. At present, in the domestic market, most of the forming m...

Problems solved by technology

When rolling the drum-shaped (concave-convex) helical compression spring, the combination of the cam mechanism can realize the forming, but it cannot be cut

It is not easy to form when rolling a spring with a large outer diameter, and cannot meet the technical requirements of a high-precision spring. Moreover, when the spring is cut off, the cutting force is large, and the mandrel will move slightly, and the processed spring is prone to tail hooks. Therefore: Unable t
