Abstract

The invention relates to a manufacturing process of a compression spring and tempering furnace filling equipment of the compression spring, and is applied to the technical field of spring manufacturing. The tempering furnace filling equipment of the compression spring comprises a filling cage, a moving assembly and a feeding pipe, multiple filling grooves are formed in the filling cage, the filling cage is detachably installed on the moving assembly, the feeding pipe is located over the filling grooves, and the moving assembly is used for driving the filling grooves of the filling cage to sequentially pass through the lower portion of the feeding pipe. The manufacturing process of the compression spring comprises the following steps of S1, winding, wherein a steel wire is fed into a spring coiling machine to be bent into the compression spring; S2, tempering, wherein the bent compression spring is put into a continuous tempering furnace; S3, spring grinding, wherein the two end surfaces of the compression spring are ground to be flat; and S4, cleaning, wherein the compression spring is cleaned through ultrasonic waves. The manufacturing process of the compression spring and the tempering furnace filling equipment of the compression spring have the effects that the compression spring is prevented from being stacked and twisted in the tempering process, and the tempering quality of the compression spring is improved.

Description

technical field

[0001] The present application relates to the technical field of spring manufacturing, in particular to a manufacturing process of a compression spring and its filling equipment for a tempering furnace. Background technique

[0002] Compression spring is a mechanical part that uses elasticity to work. It is used to control the movement of parts, alleviate shock or vibration, store energy, measure force, etc. It is widely used in machines and instruments.

[0003] In the production and manufacture of compression springs, the wire feeding frame, spring coiling machine, tempering furnace, spring grinding machine and cleaning machine are used. The steel wire is transported to the spring coiling machine through the wire feeding frame, and the compression spring rough blank is formed after cutting by the spring coiling machine. Then put it into the tempering furnace for tempering, and the compressed spring after tempering is sent to the spring grinding machine for ...

Examples

Embodiment Construction

[0035] The following is attached Figure 1-4 The application is described in further detail.

[0036] refer to figure 1 The tempering furnace 1 includes a furnace shell 11, and a steel strip 12 and a furnace roll 13 arranged in the furnace cavity surrounded by the furnace shell 11. The furnace roll 13 is arranged horizontally and both ends are rotatably connected with the furnace shell 11. The steel strip 12 is sleeved on the On the furnace roller 13, the compression spring to be tempered is placed on the strip steel 12 of the tempering furnace 1, and is driven by the strip steel 12 to move along the furnace cavity.

[0037] The embodiment of the present application discloses a tempering furnace filling equipment for compressing springs. refer to figure 1 , including the filling cage 2, the moving assembly 3 and the feeding pipe 4, the moving assembly 3 drives the filling cage 2 to move, the feeding pipe 4 loads the compression spring to be tempered into the filling cage 2,...
