With conventional spring slightly difference is spring itself is irregular, with bending Angle and a large number of complex design and manufacturing processing craft is also relatively have a requirement, equipment is more requirements are generally more computer winding machine for winding Angle, bending, so production is slow because of its complexity, shaped spring production and processing, often can represent a company's technology level.

Special spring function

What are the main functions of the shaped spring? It can control the movement of machinery, such as the monitoring of the shaped spring in clutch equipment. It can absorb shock and impact energy, such as the impact of cars, trains under the car under the shaped spring, and so on. Energy is stored and transmitted as power, such as the irregular spring in a clock. Used in force measuring devices, such as dynamometers. The spring force and deformation of the ratio is called shaped spring stiffness, stiffness is large, shaped spring is more hard.

Different kinds of springs

1. Variable diameter coil spring: it is used for some special occasions, the material of variable diameter spring is generally circular section material, and most of it bears compression load.

What is a special spring

2 pieces of spring: the spring material is spring strip (or plate), in special equipment or general pressure machining machine, through the corresponding mold processing. Sheet spring, wave spring, light spring material thickness is thinner, and medium or large spring material thickness is often thicker, the use of this kind of spring is also very wide.

3 When the installation space is limited, the spring of rectangular section material is often used, because the spring made of rectangular section material can obtain a large load under the same space and the same deformation. This type of spring has a larger cross-sectional area in the same space than a spring of circular cross-sectional material, so it absorbs more energy. It can be used in heavy machinery, stamping dies or springs with particularly high stiffness.

The butterfly spring is small in size and light in weight, used for buffering, shock absorbing and other occasions, and is widely used in stamping die, valve clutch fasteners and petroleum and geological engineering machinery.

The convex helical compression spring can obtain a large deformation because the small coil at both ends can be embedded into the middle coil. For example, some in the convex car brake spring, usually has been in and tight state, open the car valve, spring recovery deformation, drive the brake on the car brake. Hair clippers are also used in the use of the feature of the spiral spring in the convex shape, in the effective space to obtain greater deformation and stress.

A cochlea coil spring ACTS like a conical coil spring in that it is subjected to pressure and absorbs large amounts of energy. Due to manufacturing difficulties, it is only used in special cases with space constraints. The planar spiral spring has many coils, large deformation, and can store large energy. It is mainly used to compress the spring and the energy storage element in the instrument and meter.

7 torsional spring can be a single piece of spring plate or more pieces of superposition, its cushioning and damping performance is good, especially the shock absorption performance of the multi-plate spring is strong, mainly used for the suspension of cars, tractors and railway vehicles.

The coil spring with 8 different pitch is mainly used for suspension spring of motorcycle and small bus and valve spring of high speed engine. At the same time, it can meet the requirements of small stiffness in small deformation and large stiffness in large deformation. Unequal pitch springs are just the thing to meet these special requirements.

The torsion bar spring is actually a straight rod made of elastic material under the action of torque. It has large deformation energy per unit volume and is mainly used for suspension devices of various vehicles.

10 Ring spring is composed of an outer ring with an inner cone and an inner ring with an outer cone. The logarithm of the inner ring is determined according to the load bearing and deformation requirements. Ring springs have high damping capacity and are mainly used in heavy equipment and buffering devices.

11 line spring is a variety of linear springs made of spring wire, generally made of cold drawn spring steel wire. Line spring is mostly used in situations where the load characteristics are not strictly required. The section of line spring is usually round, so the load has no direction limit and has the same bending stiffness in all directions.

There are two kinds of spring clips: circular section material and rectangular section material. Sometimes, in order to facilitate assembly, the spring clips are made into ends and then bent. In the manufacture of the clamping coil, the close-wound spring coil can be self-leveling after being cut off, and the winding must have a large initial stress.

Snake-shaped spring is named after other zigzag shapes such as snakes, which are also called "Z" and "S" shaped springs according to their shapes. It is widely used in car seat, so it is also called seat spring.

More than 14 strands of coil spring generally first 0.5mm~3mm steel wire twisted into a cable, and then in the coil spring, commonly used is not with the center of 3 ~4 strands of cable. When the cable more than 4, there should be a center of the cable, in order to make the cable force is not loose, the cable should be opposite to the rotation of the spring.

The 15 clamp spring is usually used for fastening the liquid storage tank of automobile, belonging to the category of double torsion spring. This kind of spring can be rolled with CNC spring machine in qualified enterprises, the general enterprise is to use manual rolling, rolling can make some special paving.
