Advantages of precision stamping
30
June
Precision stamping components offer the following advantages: (1) Easy control and high production efficiency. These components are typically manufactured using stamping tooling and specialized equipment, making automated production straightforward. (2) The use of molds during manufacturing ensures dimensional consistency across products. (3) Modern precision metal stamping technology can produce diverse components, even those with complex designs, demonstrating broad applicability across industries.(4) Precision metal stamping parts generally produce minimal scrap during production, enabling efficient material utilization and resulting in relatively low manufacturing costs.
The manufacturing process involves operations such as blanking, bending, deep drawing, forming, and casting-rolling. The raw materials typically consist of hot-rolled or cold-rolled metal sheets (primarily cold-rolled), including carbon steel plates, alloy steel plates, spring steel plates, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloy sheets, aluminum and aluminum alloy sheets. The hardness testing of stamping materials primarily evaluates whether the purchased metal sheets’ quenching levels are suitable for subsequent stamping processes. Different types of stamping operations require the use of steel plates with corresponding strength grades.
Precision stamping components are manufactured using high-precision toolings through single-station clamping and positioning in the punching process. Given the stringent dimensional accuracy and positional tolerance requirements for workpieces on stamping machines, rigorous finishing processes including die sharpening, heat treatment, surface treatment, and assembly are essential. As these parts are typically produced in small batches or as discrete components, the machinery requirements are relatively modest. During stamping, material flows into the die cavity through gaps in the tooling or mold, where pressure-induced separation or plastic deformation forms the desired shape and structure. After pressure release and controlled process management, the finished product is obtained. This demonstrates that stamping technology represents a classic example of cold forming techniques.
In the production process, to ensure product quality and efficiency while reducing waste and conserving energy, the following practical measures should be implemented: 1. Proper tool selection. 2. Rational choice of raw materials. 3. Establishment of standardized production protocols. 4. Continuous technical training for operators. 5. Enhancement of machine automation. 6. Optimization of working conditions.
The manufacturing characteristics of stamped parts:(1) the utilization rate of materials is high.(2) it can be used to make complex products from relatively thin sheets.(3) it can be made into various structures containing structural columns.
Investigation on the causes and improvement of deformation in precision machining
30
June
The precision mechanical processing performance is not only vital to corporate interests but also safety-critical. While generating economic benefits, it significantly reduces workplace accident risks. Therefore, preventing component deformation during manufacturing is paramount. Operators must consider all relevant factors and implement preventive measures to ensure product integrity. To achieve this, analyzing deformation causes in machining processes and developing reliable countermeasures are essential. These efforts will establish a solid foundation for realizing modern enterprise development strategies.
- Analysis of the causes of deformation in precision machining
- The internal force causes the change of machining accuracy of parts
In lathe machining, the cohesive force principle is typically applied. By using the lathe’s three-jaw or four-jaw chuck to securely hold workpieces, precision mechanical processing can be performed. To ensure parts remain clamped under force and minimize internal axial stress, the clamping force must exceed the mechanical cutting force. The clamping force increases proportionally with the cutting force and decreases accordingly. This operational approach ensures stable force distribution during machining. However, when the three-jaw or four-jaw chuck is released, the machined parts often deviate significantly from the original design—some exhibit polygonal shapes, others become oval, resulting in substantial dimensional deviations.
- It is easy to produce deformation after heat treatment
Sheet metal components, characterized by their large aspect ratio, are prone to developing “hat-shaped bending” after heat treatment. This deformation manifests in two primary ways: first, midsection bulging that amplifies surface flatness deviations; second, bending induced by external environmental factors. These deformation issues arise not only from altered internal stresses post-heat treatment but also stem from operators’ insufficient expertise in component structural stability, which significantly increases deformation risks.
- Elastic deformation caused by external force
There are four primary causes of elastic deformation in mechanical processing. First, components containing internal thin plates require more precise machining techniques. When workers fail to align these components with design drawings during positioning and clamping, elastic deformation often occurs. Second, uneven surfaces on lathes and fixtures create uneven stress distribution during clamping, causing the weaker side to deform under force during cutting. Third, improper positioning during machining reduces component stiffness. Fourth, cutting forces themselves contribute to elastic deformation. These multiple factors collectively demonstrate how external forces significantly impact machining quality.
