Barrel Screw Processing Methods

Screw barrels are important parts in many mechanical equipment and are widely used in the chemical, food, pharmaceutical and plastics industries. The processing technology of screw barrel has an important impact on its performance and service life. This article will introduce the screw barrel processing technology.

I. Determine the specification parameters

Before starting to process the barrel screw, you first need to determine the required specifications, including screw length, diameter, thread parameters, materials and so on. These parameters will directly affect each step of the machining process, so they must be accurate.

Second, material preparation

According to determine the specifications, prepare the corresponding raw materials. For the barrel screw, commonly used materials include stainless steel, alloy steel, etc. Select the appropriate material according to the specific needs. At the same time, ensure that the material quality is qualified and free of defects.

Third, rough machining

The purpose of rough machining is to quickly remove most of the residual quantity, to provide a suitable benchmark for subsequent processing. This step is usually carried out by milling or turning, mainly to complete the basic shape and size of the barrel screw processing.

Fourth, semi-finish machining

On the basis of rough machining, semi-finish machining, further processing of the outer surface and part of the inner surface of the barrel screw. This step is usually carried out by turning or grinding to precisely control the size and shape. At the same time, it provides benchmarks for subsequent heat treatment and finishing.

V. Heat Treatment

According to the desired performance requirements, the barrel screw heat treatment. The heat treatment process needs to strictly control the temperature, time and cooling method to ensure that the material performance is up to standard. After heat treatment, necessary tempering treatment is carried out to stabilize the material properties.

Sixth, finishing

The purpose of finishing is to improve the surface quality and dimensional accuracy of the barrel screw. This step is usually carried out by grinding or polishing to obtain a smooth surface. At the same time, the threaded part of the barrel screw is finely processed to ensure that the thread parameters are accurate.

VII. Inspection and acceptance

After finishing, the barrel screw is strictly tested and accepted. The inspection includes size, shape, surface roughness, hardness, etc., to ensure that the parameters meet the requirements. At the same time, necessary performance tests, such as wear resistance, pressure resistance, etc., to ensure that the quality of the barrel screw is reliable.

Eight, packaging and storage

After ensuring that the quality of the barrel screw is qualified, carry out appropriate packaging to protect its integrity in the storage and transportation process. Packaging should have good shockproof, moisture-proof performance to avoid damage during transportation. At the same time, according to the material properties and environmental conditions, choose the appropriate storage method to ensure that the barrel screw is not affected by long-term preservation.
