Product Introduction of Three - Piece Die Made of Powder High - Speed Steel
I.Product Overview
The three - piece die is manufactured from high - quality powder high - speed steel. It features excellent hardness, wear resistance, and strength - toughness balance, precisely suiting various precision forming and processing scenarios. The unique three - piece structure facilitates clamping, debugging, and maintenance. It demonstrates high efficiency and stability in processes such as thread processing and complex contour forming, providing a reliable solution for the mold and precision manufacturing fields.
II. Core Material - Powder High - Speed Steel
The powder high - speed steel is prepared through advanced powder metallurgy technology. It has no segregation defects with uniform alloy composition, endowing the product with the following core advantages:
- Ultra - high Hardness: After heat treatment, the hardness can reach 63 - 66 HRC. It can withstand high - stress and high - friction working conditions and maintain the edge accuracy for a long time.
- Ultimate Wear Resistance: The synergistic effect of uniformly distributed carbides and alloying elements significantly reduces the wear rate, making it suitable for high - frequency and long - cycle processing.
- Balanced Strength and Toughness: Compared with traditional high - speed steel, its resistance to cracking and deformation is significantly improved, enabling it to handle complex stress impacts with ease.
III. Processing Flow
(I) Powder Metallurgy Blank Making
The pre - treated alloy powders (containing elements such as W, Mo, Cr, V) are densified by the hot isostatic pressing (HIP) process under the protection of inert gas to obtain blanks with uniform composition and no defects, laying a foundation for high performance.
(II) Precision Rough Machining
Methods such as CNC milling and electrical discharge machining are adopted to initially mill the contour and basic holes of the three - piece die, leaving a finishing allowance (0.1 - 0.2mm) and controlling the dimensional tolerance within ±0.05mm to ensure subsequent forming accuracy.
(III) Heat Treatment Strengthening
- Quenching: Heat to 1100 - 1200℃ in a vacuum furnace, followed by oil cooling or air cooling for quenching. Rapid cooling realizes martensitic transformation and increases hardness.
- Multiple Tempering: Undergo 3 - 4 times of tempering at 550 - 650℃ to eliminate internal stress, refine the structure, optimize the strength - toughness matching, and stabilize the dimensional accuracy.
(IV) Super Precision Finishing
- Grinding: Use a diamond grinding wheel for plane, outer circle, and分型 surface grinding. Control the surface roughness Ra ≤ 0.4μm and ensure the three - piece die splicing gap ≤ 0.01mm.
- Wire Electrical Discharge Machining: Precisely process details such as thread profiles and complex grooves with a dimensional accuracy of ±0.005mm to meet the precision forming requirements.
(V) Surface Treatment (Optional)
- Coating Treatment: Such as TiAlN coating with a thickness of 2 - 5μm, which further reduces the friction coefficient, improves wear resistance and corrosion resistance, and extends the mold life by 30% - 50%.
- Nitriding Treatment: Enhance surface hardness and oxidation resistance, suitable for high - temperature and high - corrosion processing environments.
IV. Typical Application Scenarios
(I) Thread Processing Field
- Automotive Industry: Used for cold forging/tapping forming of standard parts such as 3/8 hexagon bolts and special - shaped threaded parts, stably producing high - precision threads and adapting to the assembly of key components such as engines and chassis.
- Electronics/Home Appliance Industry: Processing of precision small threads (such as mobile phone and home appliance screws) to ensure the consistency of thread profiles and improve the assembly reliability of products.
(II) Precision Mold Forming
- Powder Metallurgy Molds: Pressing high - complexity powder metallurgy parts (such as gears and structural parts). The three - piece die can precisely form complex contours, facilitate demolding, and ensure the uniformity of part density.
- Cold Extrusion Molds: Cold extrusion forming of non - ferrous metals (such as copper and aluminum), withstanding high unit pressure. With high hardness and wear resistance, it stably produces thin - walled and high - precision parts.
(III) Manufacturing of Industrial Equipment Components
In the processing of precision components such as semiconductor equipment and high - end hydraulic components, it is used for forming/trimming key shaft - type and sleeve - type parts to ensure the operation accuracy and stability of the equipment.
V. Precautions for Use
(I) Clamping and Debugging
- Use a special fixture to clamp the three - piece die to ensure close fitting of the splicing surfaces (gap < 0.01mm). Debug the coaxiality and parallelism with a dial indicator, and control the error within 0.01mm.
- Before the first use, run the equipment with no load to verify the smoothness of mold opening, closing, and forming actions and avoid interference damage.
(II) Processing Parameter Control
- Adjust the pressure and speed according to the processed materials (such as steel and non - ferrous metals). When processing high - strength steel, reduce the single - forming speed (≤50mm/s) to avoid mold overload; when processing soft materials, optimize lubrication to reduce the risk of sticky molds.
- Strictly control the processing temperature, and equip with a cooling system (such as oil cooling and air cooling) to prevent the mold from cracking due to thermal fatigue. Especially in continuous production scenarios, detect the mold temperature (≤200℃) every 2 - 4 hours.
(III) Maintenance
- Regular Cleaning: After each shift of production, use a special cleaning agent (such as a neutral mold cleaning agent) to clean the residual debris and oil stains on the mold surface to avoid corrosion and aggravated wear.
- Rust - proof Storage: Apply anti - rust oil when idle, and store in a dry and constant - temperature (20 - 25℃) environment with a humidity ≤ 50% to prevent rust from affecting accuracy.
- Wear Detection: Detect the wear of the edge and分型 surface (using an optical microscope and a profilometer) every 10,000 - 20,000 pieces produced. If the wear exceeds 0.02mm, repair or replace it in a timely manner to ensure product quality.
(IV) Abnormal Handling
- In case of mold jamming or cracking, stop the machine immediately. After cleaning the residual parts, check the mold damage: slight chipping can be repaired by electrical discharge and grinding and polishing; if severely cracked, replace with a new mold to avoid expanding losses.
- If the product size fluctuation exceeds the tolerance during processing (such as the thread pitch diameter deviation > 0.01mm), first check the mold wear and clamping accuracy, and then adjust the equipment parameters.
VI. Product Value
With powder high - speed steel as the cornerstone and integrating precision processing and strict technology, the three - piece die achieves the value of "high precision, long service life, and stable production" in scenarios such as thread forming and precision molds. It helps enterprises reduce the mold replacement frequency (service life increased by 2 - 3 times) and the defective rate (≤1%), adapting to the strict requirements of high - end manufacturing for "precision and stability" and building a core equipment support for precision forming processing.
