Kingteam Precision Hardware's Automobile Engine Intake Valve Control Shaft

The car engine is a device that provides power to the car, and is the heart of the car, which determines the power, economy, stability and environmental protection of the car. According to different sources of power, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrids.

 

The working principle of gasoline engine (gasoline engine)

 

A four-stroke gasoline engine mixes air and gasoline in a certain ratio into a good mixture. It is drawn into the cylinder during the intake stroke. The mixture is compressed and ignited to generate heat. The high-temperature and high-pressure gas acts on the top of the piston to push the piston back and forth. Linear movement, external mechanical energy output through connecting rod, crankshaft flywheel mechanism. The four-stroke gasoline engine completes a working cycle in the intake stroke, compression stroke, power stroke and exhaust stroke.

Intake stroke: The piston moves from top dead center to bottom dead center driven by the crankshaft. At this time, the intake valve opens, the exhaust valve closes, and the crankshaft rotates 180°. The intake valve control shaft hardware in this part is the core product of Shenzhen Kingteam Precision Technology Co., Ltd.!

 

As we all know, the engine is the most "valuable" part of a vehicle body and one of the most important core technologies of a vehicle. Its reliability is closely related to the performance and quality of the vehicle. But unlike the exterior interior, we often don't see the engine structure when choosing a car.

Therefore, automobiles and their parts are products that require high-quality system management, especially any parts on automobile engines. Quality assurance and reliability were developed for the same purpose. It can be said that reliability has become the core of modern quality assurance. Reliability test is a general term for tests performed to improve or confirm the reliability of products, devices, and parts.

In addition to the conventional tests, the reliability test of automobile engine parts also includes a series of tests such as life test, critical test, environmental test and use test.

 

Shenzhen Kingteam Precision Hardware's automobile engine intake valve control shaft can withstand any high-quality system management test in the industry.

 

Kingteam Precision Hardware's automotive engine intake valve control shaft. The material of this part is 4140 alloy structural steel. 4140 steel has high strength, high hardenability, good toughness, small deformation during quenching, high creep strength and durability at high temperatures strength.

 

The machining process of the intake valve control axis mainly includes CNC turning or machining and CNC milling and grinding. CNC turning or machining and CNC milling are mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces of any cone angle, complex rotating inner and outer surfaces, cylindrical and conical threads, etc., and can perform grooving and drilling. Hole, reaming, reaming and boring, etc.

Numerical control turning or machining and numerical control milling are to automatically process the processed parts according to the pre-programmed processing program. We compile the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a machining program list according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program list On the control medium, it is then input into the numerical control device of the numerical control machine tool to direct the machine tool to process the parts.

The surface treatment of this intake valve control shaft produced by Kingteam Precision is passivated. Passivation is the last process step in chemical cleaning, and it is a key step. Its purpose is to prevent corrosion of materials. For example, after the boiler is pickled, washed with water, and rinsed, the metal surface is very clean, very activated, and prone to corrosion. Therefore, passivation treatment must be carried out immediately to form a protective film on the cleaned metal surface to slow down corrosion.

 

Shenzhen Kingteam Precision Technology Co., Ltd. is a company that has passed: IATF16949: 2016 and ISO9001: 2015 management system certification. It is mainly engaged in the production of metal precision parts, CNC lathes, CNC machining centers, automatic lathes and other products, as well as the development and production of production automation equipment Mainly a domestic enterprise, the company covers an area of more than 10,000 square meters and is located in Pingshan District, east of Shenzhen.
