QD Series Ball Joint

QD Series Ball Joint
ISUTAMI ball joint is installed between the ball head and the connecting rod body to realize the mechanical connection between the ball head and the connecting rod body and the transmission of power. The driving force of the ball head part can drive the connecting rod part to move through the ball head connecting rod.An important part of the connector is the pull rod of the ball head housing and the ball head of the steering shaft in the housing. The ball head is hinged with the edge of the axle hole of the ball head housing through the ball head seat at the front of the housing. The ball head seat and the steering spindle are embedded in the hole surface groove of the ball head housing, which can reduce the wear of the ball head and improve the tensile strength of the spindle.

QD Series Ball Joint Features

Ball joint is related to the operation and efficiency of the machine, the quality of heat treatment is directly related to the follow-up processing quality so as to ultimately affect the service performance and life of parts, and heat treatment is also a large energy consumption and pollution in the machinery industry.With the development of science and technology and its application in heat treatment, the waste water, waste gas, waste salt, dust, noise and electromagnetic radiation produced by the clean heat treatment and heat treatment of ball joint will pollute the environment.It is one of the developing directions of heat treatment technology to solve the environmental pollution problem of heat treatment and implement clean heat treatment.In order to reduce the emission of SO2, CO, CO2, dust and cinder, the use of coal as fuel has been basically eliminated, and the use of heavy oil is becoming less and less. The majority of people use light oil, and natural gas is still the most ideal fuel.The utilization of waste heat in combustion furnace has reached a high degree.

The optimization of burner structure and strict control of air-fuel ratio ensure the reasonable combustion and reduce NOX and CO to the minimum.Use gas carburizing, carbonitriding and vacuum heat treatment technology instead of salt bath treatment to reduce waste salt and pollution of water source with cn-toxic substances;Water soluble synthetic quenching oil was used to replace part of quenching oil and biodegradable vegetable oil was used to replace part of mineral oil to reduce oil pollution.Ball joint precision heat treatment is based on the use of parts requirements, materials, structure size, the use of physical metallurgy knowledge and advanced computer simulation and testing technology, optimize process parameters, to achieve the required performance or maximize the potential of materials.The stability of the optimized process is fully guaranteed, and the product quality dispersion is very small and the heat treatment distortion is zero.The scientific production and energy management of energy saving heat treatment of spherical joint is the most potential factor for the effective utilization of energy.In terms of energy structure of heat treatment, primary energy is preferred.Make full use of waste heat and waste heat;Adopt low energy consumption and short cycle instead of long cycle and high energy consumption.
