Abstract

The invention relates to a cylindrical steel plate cone spring, and belongs to the technical field of springs. The cone spring is manufactured by the following steps: (1) manufacturing a spring material plate, namely, selecting straight steel plates according to the inside diameter, outside diameter, height, thickness and turn number of a designed spring, drawing an expansion plate material graph in a spiral evolution mode, and cutting the spring steel material plate; (2) manufacturing a coil spring mandrel, namely, manufacturing the mandrel with a large head, a small head and a cone according to the inside diameter, outside diameter, the height, the thickness and the turn number of the designed spring; (3) winding the spring, namely, winding a trumpet-shaped primary spring ring of the cone spring manufactured with a large end and a small end by using the cone at one end of the mandrel, then using the small end of the trumpet-shaped spring ring to replace the mandrel to manufacture a next large end ring of the cone spring by winding, and using the cylinder of the mandrel to manufacture a next small end ring of the cone spring by winding. The cylindrical steel plate cone spring has a simple, reasonable and scientific structure, novel and attractive appearance, small volume, and large bearing capacity, and meets the requirements of the bearing capacity of various mechanical devices at home and abroad.

Description

Column steel plate pagoda spring and manufacture method thereof

Technology neck or

The present invention relates to a kind of structure and method of manufacturing technology thereof of spring, particularly a kind of manufacture method of leaf spring of pagoda shape belongs to the spring technical field.

Background technique

Spring is widely used a kind of elastic element in machinery and the electron trade, spring can produce bigger resiliently deformable when stand under load, mechanical work or kinetic energy are converted into energy of deformation, and the distortion of unloading rear spring disappears and reinstatement, and energy of deformation is converted into mechanical work or kinetic energy.Along with developing rapidly of economic and science and technology, many equipment or place need the spring of special construction, and existing belleville spring, annular spring, leaf spring, helical spring, valute spring, torsion bar spring all can not satisfy its requirement.

Summary of the invention

The objective of the invention is provides a kind of volume is little, bearing capacity is big a kind of column steel plate pagoda spring and manufacture method thereof for satisfying the demand in market.

The object of the present invention is achieved like this, and column steel plate pagoda spring is characterized in that being made of with the progressive shape coiling of spiral a Steel Spring Plate, and the spring ring flare holds snare greatly on the small end circle.

The manufacture method of above-mentioned column steel plate pagoda spring may further comprise the steps:

(1) preparation spring flitch, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, select straight steel plate for use, draw pagoda spring with the progressive shape of spiral and launch plate figure, tailor the spring steel flitch;

(2) preparation wind spring mandrel, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, preparation has the mandrel of CONCENTRIC REDUCER and cone;

(3) wind spring, with the reel first circle spring ring of the pagoda spring flare that is manufactured with big small end of the cone of an end on the mandrel, small end with flaring spring ring replaces next big end circle that the mandrel coiling is made pagoda spring then, reels with the cylindrical body of mandrel and makes next small end circle of pagoda spring.

Simple and reasonable, the science of the present invention, the outward appearance novel and beautiful, volume is little, bearing capacity is big, has satisfied domestic and international many machinery and has required bearing capacity.

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is the mandrel structural representation that wind spring of the present invention is used;

Fig. 4 is the right elevation of Fig. 3.

Among the figure: 1 first circle spring ring, 2 big end circles, 3 small end circles, 4 cones, 5 cylindrical bodys.

Embodiment

As shown in Figure 1 and Figure 2, column steel plate pagoda spring is made of with the progressive shape coiling of spiral a Steel Spring Plate, and the spring ring flare holds snare greatly on the small end circle.Its step:

(1) preparation spring flitch, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, select straight steel plate for use, draw pagoda spring with the progressive shape of spiral and launch plate figure, tailor the spring steel flitch;

(2) preparation wind spring mandrel, as shown in Figure 3, Figure 4, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, preparation has the mandrel of cylindrical body 5 and cone 4;

(3) wind spring, adopt spring coiling machine, with reel first circle 1 spring ring of the pagoda spring flare that is manufactured with big small end of the cone 4 of an end on the mandrel, small end with flaring spring ring replaces next big end circle 2 that the mandrel coiling is made pagoda spring then, reels with the cylindrical body 5 of mandrel and makes next small end circle 3 of pagoda spring.

Rolled spring is put in storage again through operations such as heat treatments.

Claims (2)

1, a kind of column steel plate pagoda spring is characterized in that being made of with the progressive shape coiling of spiral a Steel Spring Plate, and the spring ring flare holds snare greatly on the small end circle.

2, the manufacture method of column steel plate pagoda spring as claimed in claim 1 is characterized in that may further comprise the steps:

(1) preparation spring flitch, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, select straight steel plate for use, draw pagoda spring with the progressive shape of spiral and launch plate figure, tailor the spring steel flitch;

(2) preparation wind spring mandrel, according to the inside and outside footpath of design spring, highly, thickness and the number of turns, preparation has the mandrel of CONCENTRIC REDUCER and cone;

(3) wind spring, with the reel first circle spring ring of the pagoda spring flare that is manufactured with big small end of the cone of an end on the mandrel, small end with flaring spring ring replaces next big end circle that the mandrel coiling is made pagoda spring then, reels with the cylindrical body of mandrel and makes next small end circle of pagoda spring.
