Гайки с накаткой – Эксклюзивный Применение in manufacturing equipment for production processes

Я. Overview of the Core Process of Knurled Nut Manufacturing

Ganyuan Hardware has consistently adhered to the core process of “сырье → грубая обработка → точная обработка → насечка → обработка поверхности → проверка готового изделия” for many years in the production and processing of knurled nuts. Each step requires corresponding specialized mechanical manufacturing equipment to ensure that the product’s precision, прочностью, and surface quality meet industrial-grade standards.

(Я) Raw Material Pre-selection

The selection of raw materials for knurled nuts must consider processing performance, механическими свойствами, и требований к применению. В настоящее время, the most widely used materials in industrial production are high-quality carbon steel, нержавеющей стали, and C3604 environmentally friendly brass. Some high-end or special applications may use materials such as aluminum alloy and alloy steel. The specific characteristics of each type of raw material are подробно ниже.

(II) Rough Machining Stage: CNC Lathe and Drilling Machine

The core of the rough machining stage is to process the shape of the tempered blank, removing excess material and initially forming the basic outline of the knurled nut, laying the foundation for fine machining. The core equipment used is a ЧПУ токарный станок and a vertical drilling machine, balancing efficiency and precision.

1. Токарный станок с ЧПУ: As the core equipment for rough machining, it is mainly used for machining the outer diameter and length of knurled nut blanks, as well as for preliminary drilling of the inner hole. The equipment adopts a CNC system, which can preset machining parameters to achieve automated machining with a machining accuracy error ≤0.01mm. Во время работы, the blank is clamped on the chuck, and the spindle drives the blank to rotate at high speed. Combined with a carbide cutting tool, the outer diameter of the blank is precisely cut to the preset size, while simultaneously cutting the end face, controlling the product length, and completing the preliminary drilling of the inner hole.

2. Vertical Drilling Machine: Assists the CNC lathe in completing the rough machining of the inner hole, mainly for large-sized knurled nuts or products with complex inner hole dimensions, accurately drilling holes and removing burrs from the inner hole. The equipment adopts a vertical structure with the spindle pointing vertically downwards, allowing for precise positioning of the drilling location. The drilling accuracy error is ≤0.03mm.

(III) Заключительная стадия: CNC Milling Machine, Tapping Machine, and Grinding Machine

The finishing stage is the core link in improving the accuracy of knurled nuts. It mainly involves internal thread machining, external finishing, and internal hole grinding of the rough-machined blank to ensure that the product dimensions, Точность, and surface roughness meet industrial-grade standards. It utilizes three types of precision mechanical manufacturing equipment combined with precision cutting tools to achieve refined machining.

1. CNC Milling Machine: Used for external finishing and special structure machining of knurled nuts. The equipment adopts a three-dimensional CNC system, enabling multi-dimensional precise cutting with a machining accuracy error ≤0.005mm. Во время работы, the rough-machined blank is clamped on the worktable, and the milling cutter rotates at high speed to precisely cut off excess material, finishing the product shape to ensure accurate dimensions and a smooth surface.

2. Internal Hole Grinding Machine: Used for precision grinding of the inner hole of knurled nuts, further improving the accuracy and surface smoothness of the inner hole, ensuring the compatibility of the internal thread with the bolt. The equipment adopts precision grinding technology, equipped with a diamond grinding wheel, which can accurately grind the inner wall of the hole, making the inner hole size error ≤0.003mm and the surface roughness Ra≤0.8μm, while correcting the coaxiality of the inner hole and outer diameter.

(V) Surface Treatment Stage: Electroplating Equipment

Knurled nuts require surface treatment to improve corrosion resistance and wear resistance, extend service life, and adapt to complex working conditions such as industrial humidity and high temperature. The core application is electroplating equipment, achieving standardization of the entire surface treatment process.

1. Fully Automatic Electroplating Equipment: Employing rack plating or barrel plating methods, the appropriate process is selected according to the specifications of the knurled nut. The core function is to electroplat a metal layer on the nut surface, improving the product’s corrosion resistance and aesthetics. The equipment employs an automated control system, precisely controlling electroplating time, current, and voltage to ensure uniform plating thickness (0.01-0.03мм).

(VI) Finished Product Inspection Stage: Precision Inspection Equipment

Finished product inspection is the last line of defense in ensuring the quality of knurled nuts. The core is to inspect product dimensions, точностью, текстуры, качеству поверхности, and other indicators, eliminating unqualified products. Three types of precision inspection equipment are used to achieve precise inspection throughout the entire process, ensuring a product qualification rate of over 99.8%.

1. Two-Dimensional Image Measuring Instrument: Used to inspect the external dimensions, внутренних диаметров отверстий, точности резьбы, and texture dimensions of knurled nuts. The equipment uses a high-definition camera and image processing system, accurately measuring various dimensional parameters with a measurement accuracy ≤0.001mm. It can display measurement data in real time and is particularly suitable for inspecting fine parameters such as the depth and spacing of the knurling pattern, ensuring the pattern meets design requirements.

2. Твердомер: Used to test the hardness of knurled nuts. Its core function is to verify whether the hardness of the product after heat treatment and surface treatment meets the standard (HRC28-32). The equipment is easy to operate, can quickly measure product hardness, and displays the measurement results in real time, avoiding product wear and deformation caused by insufficient hardness, and ensuring that the knurled nuts have good mechanical properties.

3. Тестер шероховатости поверхности: Used to test the surface smoothness of knurled nuts, focusing on the roughness of the outer surface, inner wall of the hole, and knurled surface. It ensures that the surface roughness meets the industrial-grade standard (Ra≤1.6μm), avoiding problems such as assembly jamming and accelerated wear caused by surface roughness. It also ensures that the knurling pattern is clear and uniform, improving the product’s anti-slip performance and engagement.

II. Equipment Collaboration and Quality Control: Creating High-Reliability Knurled Nuts

During the knurled nut manufacturing process, various mechanical manufacturing equipment do not operate independently but form a collaborative system: from raw material cutting to rough machining, fine machining, накатку, обработка поверхности, и проверки готовой продукции, the equipment in each process is precisely connected. Parameter linkage is achieved through a CNC system, ensuring that processing accuracy and efficiency are improved simultaneously.
