Many different kinds of special-shaped spring, in order to don't introduce:
1, variable diameter coil spring: it is used in some special occasions, variable diameter of spring material generally for circular cross section, and mostly under compression load;
2, slice spring: the spring material for spring strip (
Or plate)
, on the device or general pressure machine, through the corresponding mould processing.
Leaf spring, waveform spring, light spring material thickness is thinner, and medium or large disc spring material thickness tends to thicker, this kind of spring is also very extensive USES;
3, in the limited space, often with rectangular section materials of the spring, because spring made of rectangular section materials can be in the same space and obtain larger load under the same deformation.
This kind of spring compared with circular cross section material of spring, in the same space, its cross-sectional area is large, so it absorbs energy is also big, as shown in the figure below.
It can be used in heavy machinery, stamping die or stiffness particularly big spring;
4 small size, light weight, disc springs, is widely used in the buffer, vibration absorber, etc, and in stamping die, valve type clutch fasteners and widely application on petroleum and geological engineering machinery;
5, the convex ends because of the smaller spiral compression spring spring coil can be embedded into the circle in the middle, and so the larger deformation can be obtained.
For example, some of the convex type auto brake spring, and has been in a tight state at ordinary times, open the car valve, spring back deformation, drives the brake of automobile brake.
Haircut convex pusher is also used in helical spring this characteristic, the effective space to obtain larger deformation and stress;
6, volute spring and the role of the conical helical spring are similar, it absorbed energy under pressure is big, because of manufacturing difficulties, only used for the special case of restricted by empty asked.
Plane volute spring coil number is more, the deformation is larger, can store larger energy, more energy storage components for use in the compression spring and instrumentation;
7, plate spring available monolithic spring plates or more pieces stacked together, the cushioning and vibration damping performance is good, especially more plate spring vibration isolation performance is strong, it is mainly used for automobile, tractor and railway vehicle suspension;
8, ranging from pitch spiral spring is mainly used for motorcycles and small passenger car suspension spring and high speed engine valve spring etc.
On the same piece of spring stiffness is small, at the same time can not only satisfy the deformation hours and can satisfy the requirement of stiffness big large deformation.
Ranging from pitch spring just can satisfy the special requirements;
9, torsion bar spring is actually a is made of elastic material by torsion rods, energy per unit volume deformation is large, it is mainly used for all kinds of vehicle suspension system;
10, ring spring with cone outer ring and inner ring with outer cone to cooperate and become, inside and outside the circle of the logarithm according to the requirements of the size of the load and deformation to decide.
Ring spring with high damping capacity, it is mainly used for heavy equipment and buffer device;
11, line spring is made by the spring wire various linear spring, generally made of cold drawn spring steel wire.
Line spring is used to load more smaller, no strict requirements of occasions to load characteristic, wire springs section often for round, so there is no limit to the direction of the load, bending stiffness with the same in every direction;
12, spring retainer ring has a circular cross section material and two kinds of rectangular section material, sometimes for ease of assembly, also have will be made end to bend a retainer ring.
When manufacturing retainer ring, a tightly wound spring coil can smooth after cutting, winding must have a larger initial stress;
13, coil spring is named for its shape twists and turns like a snake, according to its shape is also called the 'Z' form and 'S' shape spring, etc.
It is widely used in car seat cushion, so also known as the spring seat;
14, helix spring is generally to 0.
5 mm ~ 3 mm steel wire to wire, and then rolled into the spring, commonly used is 3 ~ 4 shares without center stock cable.
When over 4 strands, wire should be center, in order to make the cable force is not loose, after wire XuanXiangYing and rotate to the opposite of spring;
15, clamp spring is often used in automobile storage tank and other fastening, belongs to the category of double
torsion spring.
This spring in the conditional enterprise can be rolled with CNC spring coiling machine, and general enterprises is rolled by hand, rolling can make some auxiliary equipment.
Plate material cutting, straightening first, and then made into 'U' type, and rolling bent on assistive devices, assistive devices can be used with fan-shaped gear feeding spring coiling machine, using the spring coiling machine feed back and forth agencies will also 'b' is placed in the position of the feed roller, can realize the clamp spring curved semi-automatic production, production efficiency about 10 times higher than that of manual operation.
special-shaped spring forming machine is usually refers to the production of various kinds of extension spring, torsion spring and all kinds of snap ring and other elastic element forming equipment.
This kind of machine the complexity of the higher than rolling compression spring spring coiling machine, also known as transfer machine tools.
saucer-shaped special-shaped spring small size, light weight, widely used in the buffer, vibration absorber, etc, and in stamping die, valve type clutch fasteners and widely application on petroleum and geological engineering machinery.
spring available monolithic spring steel plate or multichip superposition, the cushioning and vibration damping performance is good, especially more plate spring vibration isolation performance is strong, it is mainly used for automobile, tractor and railway vehicle suspension.
