Q:Want to practice how to use pectoral muscle spring expander

The most simple way you can lie on the bed or on the floor and chest stretching is very effective and pay attention to more, so as not to hurt the small set of muscles.It takes at least one month to bear fruit

Q:Is the car short spring good?

Because of the short spring, the fluctuation of the whole suspension system is too small, and the damping of the shock absorber system changes too directly, so that the comfort of the vehicle will decrease. That means it's going to be pretty bumpy.

Q:What is flat steel? Plain carbon flat steel? Spring flat steel

Flat refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Plain carbon flat steel refers to carbon content of 0.06-0.22% flat steel. The spring flat steel refers to the flat steel with good elastic deformation ability.Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.

Q:How should we choose the spring material?

Whether the spring is good or not is of great importance to the choice of the spring material. In general, selection of spring material, should take into account the load properties, spring force, various factors should be size, working conditions and price, etc.. Specific can follow the following principles: 1) in determining the shape and size of spring material, should be preferred dimensions behind national standards or standard stipulated, try to avoid using non standard materials. Although the spiral spring square or rectangular cross section material, the elastic deformation can be higher than, can make the small volume of the spring, for spring, in small space or under impact load but because of square or rectangular section material shortage, the price is higher, and the spring forming is difficult, so should be avoided. Ring section spring material diameter series see table 3-9. 2) the degree of cold plastic deformation of cold drawn spring materials is high. Most finished steel wires have reached the required mechanical properties when they leave the factory. The surface quality of the steel wire is high, and the manufacturing process of the spring is simple. For springs of medium or small spring or high fatigue life, the cold spring or cold drawn spring or steel wire or strip shall be selected as far as possible. Carbon spring steel wire (group I, group II, group II A, dish group) and important uses of 65Mn spring steel wire during the cold drawing process caused in large residual stress, the larger the size change after low temperature tempering, and thus affect the dimensional accuracy of the spring. For the bending radius of smaller tension and torsion spring, as well as smaller steel wire compression...

Q:How to process Spring Steel

Spring steel has excellent comprehensive performance, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization, precise shape and size).

Q:The shop glass spring door is too tight, how to adjust?

It is better to ask professionals to deal with the danger!

Q:Hydraulic diagram of the one-way valve has two kinds of drawing, with a spring, without a spring, what is the difference between automatic reset function is not? Without a spring, it will not be repeated

The simplified method of drawing without springs is the same

Q:The glass door spring is broken. How much would it cost to change it?

60-100, you don't have to listen to them to buy too expensive

Q:Buffer spring buffer for automobile

Rubber buffer also known as buffer, buffer, buffer block, rubber shock absorber, shock absorber rubber and so on, the most correct name is "automobile spring cushion", is the name of Car Spring Buffer Retainer English, 1 luxury cars with a buffer principle significantly improve the damping performance of vehicles.
