Spring-strengthened shot blasting machineSpring-strengthened shot blasting machine
There are many types of shot blasting machines. Today, we will professionally introduce the spring shot blasting machine.
Spring shot blasting machines are strengthening equipment specifically manufactured for the surface treatment of springs. Shot blasting strengthening is a process specially designed to enhance the fatigue strength of components subjected to alternating stress. Friendly Casting Machinery Company is a manufacturer specializing in the production of spring shot blasting machines and spring shot blasting strengthening machines. When choosing equipment, you can select either the crawler type or the hook type. Generally, more users choose the crawler type shot blasting machine for spring strengthening.
Here is a detailed introduction to the spring shot blasting machine for everyone.
I. Spring Manufacturing Process.
A spring is merely an accumulator. It has the function of storing energy, but it cannot release the energy slowly. To achieve the function of slow release, it should be realized by "spring + large transmission ratio mechanism", which is commonly seen in mechanical watches. Springs have been in use for a very long time. Ancient bows and crossbows are two types of springs in a broad sense. Strictly speaking, the inventor of the spring should be the British scientist RobertHooke. Although helical compression springs had already emerged and been widely used at that time, Hooke proposed "Hooke's Law "- the elongation of a spring is directly proportional to the magnitude of the force it acts on. It was based on this principle that in 1776, the spring scale using helical compression springs was invented. Before long, a spring specifically designed for clocks and watches based on this principle was also invented by Hooke himself. A spring that conforms to Hooke's Law is a true spring in the real sense. The disc spring was invented by the Frenchman Berleville. It is a washer-type spring with a conical cross-section made of metal sheet or forged billet. After the emergence of modern industry, in addition to disc springs, new types of springs such as gas springs, rubber springs, coil springs, die springs, stainless steel springs, air springs and memory alloy springs have also appeared.
The steel shot from the shot blasting machine is projected onto the surface of the workpiece without compressive and tensile stress, obtaining a regional distribution of pressure and tension. When the high speed of the shot projected onto the workpiece surface reaches 80-90M/S, it can cause uniform indentations. Under the shot blasting surface, the metal will deform, and the balance of the two forces generates a compressive force inside the metal. In the upper layer, this pressure acts on the surface from both tangential and vertical directions. In the lower layer, this tension causes permanent deformation, which is smaller than that caused by pressure. Workpieces that need shot blasting hardening must complete the initial stress before being used. Surface strengthening can make the stress consistent. Especially during continuous strengthening, the surface tension of shot blasting strengthening is weakened. This is why shot blasting strengthening can improve the fatigue strength of metals
Ii. Introduction to the Crawler Spring Shot Blasting Machine.
The crawler type shot blasting machine is a medium and small-sized shot blasting equipment. It uses high-strength wear-resistant rubber tracks or manganese steel belts to flip the springs, and then the shot blasting machine projectiles the surface of the springs, thereby achieving the effect of cleaning and strengthening. This kind of equipment is also widely used in many industries, such as the cleaning, rust removal and strengthening processes of castings, forgings, stampings, gears, springs and other industries. It is particularly suitable for use on workpieces that are not afraid of collision. It can be used in wiring or as a single machine. This kind of equipment varies in price depending on its configuration and size. The cheaper ones cost over 20,000 yuan, while the more expensive ones can cost over 100,000 yuan.
Iii. Selection of Spring Shot Blasting Machines.
In addition to choosing the crawler type shot blasting machine, users can also select the continuous through type, hook type, multi-station rotary table type, suspension chain type, etc.
Iv. Technical Parameters of Spring Shot Blasting Machine.
The following are commonly used technical parameters, which users can freely select and configure.
Suitable spring diameters: 70-200mm.
2. Spring length: 100-500mm.
3. Equipped with a dust removal system, it meets national environmental protection standards.
4. plc control, automatic loading and unloading. Users can also choose manual loading, which will reduce the input cost.
5. It can clear several hundred kilograms at a time. If the production volume is large, it can be increased to several tons at a time.
6. Cleaning time. If it is merely about removing impurities and rust, the general cleaning time is about 5 to 10 minutes. If a strengthening effect is to be achieved, then one cleaning session will take approximately 20 minutes.
