Reducing mechanisms for eight-axis spring forming machine

Abstract

The invention provides reducing mechanisms for an eight-axis spring forming machine, and belongs to springing machining mechanical equipment. Each reducing mechanism comprises a servo motor, a support, a nut, a ball screw, a sliding block base, a sliding block, a reducing cutter holder, a reducing cutter, a front wallboard, concave V-blocks and convex V-blocks. In the invention, the reducing mechanisms are designed by combining a computer closed-loop technology with a reducing three-axis design; machining procedures of the reducing mechanisms for the spring forming machine are controlled by computer programs, thus realizing intelligent operation, improving performance and reliability of the machine, achieving high sensitivity and fast response speed as well as accurate dimensional accuracy, reducing manual operation amount, improving operating efficiency, ensuring safety and convenience in operation and saving energy consumption; combinations of the convex V-blocks and the concave V-blocks at 70 degrees are respectively utilized as guide rails of the sliding block and the sliding block base, which reliably and stably ensures dimensional accuracy of external diameter and shape accuracy of the spring to be machined; and by utilizing the three-axis design, the machining accuracy of the product is high, thus 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 diameter-changing mechanism of an eight-axis 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 machines for coilin...

Problems solved by technology

Among them, the reducing mechanism plays a very important role in the spring forming process, and can roll out springs with different radii. At present: on the market, most spring forming machines use two reducing mechanisms, the upper reducing mechanism and the lower reducing mechanism. It can work normally when processing a spring with a small winding ratio, but once a spring with a large winding ratio is processed, it is not easy to form, the spring quality and production efficiency are low, and the ideal technical effect cannot be achieved.

In the same industry in China: scientific research units and enterprise scientific and technological personnel are constantly researching, exploring, and improving the structure of the variable diameter mechanism of the spring forming machine. Although some progress has been made in technology, there are still technical problems that have not been overcome in practical application. Hope to develop a high-quality variable diameter mechanism
