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

[0031] 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:

[0032] The first step: equipment modification

[0033] Retrofit the CNC coil spring machine equipment to coil multi-layer wave spring equipment;

[0034] 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 the first servo motor 1, the second servo motor 13, the third servo motor 23, the first roller 2, the second roller 5, the third roller 7, the fourth roller 9, the fifth roller 10, and the sixth roller 12 , the first guide plate 3, the second guide plate 8, the third guide plate 11, the gear 4, the adjustment screw 6, the outl...

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...
