Spring manufacturer in producing pressure spring often arise in the process of the common problems

In the process of producing pressure spring spring manufacturer common problems often arise in the ( 1) Spring after forming, generally require 220 ￣ 330 ℃ low temperature to remove stress annealing or processing, or according to the operation conditions of spring and the nature of the selected material requirements, the need for hardening and tempering, in order to improve spring force. But spring heat treatment should be chosen when
fixture, in case the narrow circle, with mandrel work card. Like other outside removing two side edges, radial inside dish spring outside the burr, etc. , also cannot be ignored. Encounter has a tendency to bending spring, usable article a circle, on the spring tension along the axis of the longitudinal repeatedly rub, to the partial surface hardening. ( 2) Spring does not reach the designated position failure mode and the reason: in practice, a spring factory often encounter spring can't push the moving object set to the location, that is to say, the calculation of spring free length shorter. At the beginning of the main reason is no compression processing, is a manufacture of spring, with large tower spring force to compress it down to his height (or and tight If necessary) , after let go, cannot return to his original free length of operation. At the beginning of the shortening amount known as the 'compression'. Generally repeated 3 ~ 6 times after compression, no longer to shorten the length, namely the spring 'localization'. At the beginning of the spring before and after the compression permanent deformation. ( 3) Precaution: in practice, a pressure spring
even if is beyond the power of materials beyond the elastic limit, also should be able to maintain production retainer ring its working length. As a result, the length of the finished product spring shall be equal to the calculation of the spring length and initial amount of compression, can avoid spring does not reach the designated position, so as to avoid dangerous stress during spring coil and tight and lead to spring sex line
an exception occurs and is not in place. Spring finished product in the process of heat treatment, especially the need to the hardening and tempering process, must be the workpiece cross ( Lie) In the furnace to prevent spring due to the weight of shorter lead to work not in place. ( 4) Spring force is insufficient to the requirement of spring, which is under the regulation of deformation must produce certain spring force, once remove load, spring from free length recovery, and the moving part goes on to the set position successfully. But sometimes I can't due to lack of spring force in place. There are technological factors, such as spring in the stretching process, must overcome between circle and circle, circle and core shaft or sleeve, generated by the friction between moving pair, the vast changes (sometimes friction Up to + / - 50%) , will cause the spring force is insufficient, can't overcome the friction to make moving parts in place, resulting in a spring failure. Therefore, must according to the production process of each working procedure such as filter material, spring forming, on both ends of the smooth and remove sharp edges, heat treatment, correct adjustment, at the beginning of compression processing, inspection refueling strictly implemented.
in addition, the spring force and the design, material selection and so on. From two main formula to calculate the deformation formula of reed: lambda = 8 pd32n tau = K8PD2 / PI/Gd4 and stress formula d3,
spring force by steel wire diameter, coil diameter, deformation and influenced by the number of turns, with the characteristic of material, environment temperature, load characteristics, and is closely related to the dynamic effect, and can lead to spring force and deformation in line an exception occurs.
Maintaining leaf spring hardware is not as easy as it may seem. You have to do plenty of important tasks. So cruel is the truth unless you've got a to help you.
