Manwosi: Compression test of automobile damping spring tension testing machine

Most cars use coil springs, and some pneumatic (suspension) cars use air springs. Today, as a small editor of Nanjing manwosi automobile shock absorber company, I bring you the relevant contents of shock absorber spring tension testing machine:

classification

It is mainly divided into four categories: compression spring, rubber spring, composite spring, airbag spring, etc.

Automobile damping spring is made of spring steel. Spring steel refers to the steel specially used to manufacture springs and elastic components due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its ability of elastic deformation, that is, within the specified range, the ability of elastic deformation makes it bear a certain load, and there is no deformation after the load is removed.

Main purpose of damping spring damper (damping spring damper):

1. All kinds of heavy machinery

2. Cooling water tower

3. Fire pump, various fans, air conditioner

4. Generator, air compressor

Application:

Medical instruments: needle less syringe spring, blood sampling needle spring

Communication industry: IC optical fiber connector spring

Automobile industry: leaf spring, coil spring, clutch spring, accelerator pedal spring, cylinder safety valve spring of locomotive and tractor, as well as some important springs working under high stress and high wear springs.

Test equipment:

Test method:

The test force of the spring can be set to detect the residual height or deformation of the spring; The residual height of the spring can also be set to detect the test force, which overcomes the influence of the spring rebound stress on the test data and automates the whole test process.

Reference standard: GB / t228 1-2010 metallic materials tensile test Part 1: room temperature test method

matters needing attention:

The spring needs to test the repeatability of stiffness (this can be measured, and the repeatability of test data can be compared by doing several tests continuously). The deformation error of each force measuring point is very small. The electronic universal material testing machine mainly tests the tension and strength. The spring machine requires deformation force measurement and height force measurement, which must ensure that the equipment does not deform or does not deform within the accuracy range. There are many kinds of springs, such as aerospace industry, petroleum machinery industry, power equipment industry, industrial machinery industry, agricultural machinery industry, HVAC equipment industry, amusement facilities industry, industrial industry, automobile industry, etc. Manworth measurement and control tensile testing machine also establishes a variety of databases for users, such as locomotive bolster spring, axle box spring, brake spring, automobile oil pump check valve spring, etc. During the test, it can be called at will.
