Problems solved by technology

The disadvantage is that the processed products have out-of-round phenomenon. For multi-layer wave springs, the peaks and troughs do not correspond, the misalignment shifts, the layers are not close enough, and the loose phenomenon is easy to deform, the product qualification rate is low, and the production efficiency is low.

Embodiment

[0030] A manufacturing method of a wave spring, characterized in that the CNC spring coiling machine equipment is refitted into winding multi-layer wave spring equipment for production, and the method is as follows:

[0031] The first step: equipment modification

[0032] Retrofit the CNC coil spring machine equipment to coil multi-layer wave spring equipment;

[0033] As shown in Figure 1, it is a schematic diagram of the equipment structure of the CNC spring coiling machine. The CNC spring coiling machine was originally a five-axis linkage CNC machine with five servo motors driving the X-axis, Y-axis, Z-axis, A-axis, and B-axis. The device consists of servo motors 1, 13, 23, rollers 2, 5, 7, 9, 10, 12, guide plates 3, 8, 11, gears 4, adjusting screw 6, outlet guide plates 14, rotating wheels 15, 21, Turning wheel mechanism 16,22, cutter 17, guide wheel mechanism 18, guide wheel 19, probe device 20, guide wheel 24, power source 25, equipment frame 26, X axis mechanism 36 and...

Abstract

The invention relates to the manufacturing of a wave shape spring that modifies the CNC spring roller into several-layer spring equipment for production, for the benefit of improving productivity, quality, feature, dimension, cosmetic for mass production.

Description

technical field [0001] The invention relates to a manufacturing method of a wave spring, which can be used in hydraulic valve industries such as military industry, petrochemical industry, steel, metallurgy, shipbuilding, etc., and is applied to occasions where the load and deformation are not large, and the spring stiffness is small and axial preload is required. , belongs to the technical field of spring manufacturing methods. Background technique [0002] Wave spring is referred to as wave spring for short. It is usually processed and formed by metal steel strip. The current processing method adopts the traditional hand-made method, that is, the wire is wound into a flat ring and formed by a special forming mold. The disadvantage is that the processed products have out-of-round phenomenon. For multi-layer wave springs, the peaks and troughs do not correspond, the misalignment shifts, the layers are not close enough, and the loose phenomenon is easy to deform, the product q...
