The processing of metal stamping parts includes punching, bending, Deep Drawing, forming, finishing and other processes. The processing materials of stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, including alloy steel plates, carbon Steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.
Alloy stamping parts are the most commonly used parts in the field of metal processing and mechanical manufacturing. Metal stamping parts processing is a processing method that uses molds to separate or form metal strips. The main purpose of hardness testing of metal stamping parts is to confirm the purchase Whether the annealing level of the sheet metal is suitable for the processing of stamping parts that will be stopped later, different types of stamping parts processing techniques require sheets of different hardness levels.
The aluminum alloy plate used for stamping parts processing can be tested with a Webster hardness tester. When the thickness of the material is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester.
Reasons for poor size of metal stamping parts
- 1. Poor mold design or processing and assembly lead to poor dimensions. Such a situation usually appears at the time of the first consumption.
- 2. The height adjustment position of the mold does not match when the mold is set up, the mold cannot be in place when the metal is stamped, and the size is not consistent, or the die head is not locked after the conditioner mold, and the mold height runs off during the metal stamping.
- 3. The hardware is not placed in a precise position during the positioning of the metal stamping, and the punching piece will increase the gap between the molds and cause poor size.
- 4. The positioning of the mold is loose, and the metal stamping parts are offset when positioning, and the metal stamping causes poor size.
1. Requests for data performance of automobile compartment parts
The shape of automobile compartment parts is not too complicated, and most of them use roll forming process. There are certain requirements for the formability, rigidity, corrosion resistance and weldability of the material. Generally, high-strength steel plates with better shape properties and weldability are used. Generally, high-strength steel plates and ultra-fine grain steel with a strength level of 300-600MPa are used.
2. Requirements for data performance of automobile cab parts
Automobile cab parts are mostly cover parts, with complex shapes and complex shapes, but they are not stressed. Using mold forming technology, the forming performance of the materials has become the main contradiction. Therefore, the materials are requested to have formability, tension rigidity, and extensibility. , Concave resistance, corrosion resistance and weldability, etc. When designing automotive hardware stamping parts, the type of steel plate is usually selected according to the stress condition of the plate part and the level of complex shape.
Generally, low-carbon cold-rolled steel sheets and ultra-low-carbon cold-rolled steel sheets with excellent drawing properties are selected. In recent years, phosphorus-containing cold-rolled steel sheets with excellent formability and higher strength, cold-rolled steel sheets with high bowness, cold-rolled dual-phase steel sheets, bake-hardened cold-rolled steel sheets, ultra-low carbon steel, high-strength cold-rolled steel sheets, and others Varieties of steel plates, such as coated steel plates, tailor-welded steel plates and TRIP steel plates, are also widely used in automobile body parts such as door outer panels, door inner panels, door reinforcement panels, roof covers, trunk covers, and bumpers.
Hardware refers to the five metal materials consisting of gold, silver, copper, iron, and tin. It is widely used in industry. Hardware can be called the “mother of industry” and the “foundation of national defense” has an important position. Copper, brass, phosphor bronze, stainless steel, iron, aluminum, carbon steel, nickel, and spring steel are commonly used materials for metal stamping parts, which are included in most of our processed metal stamping parts.
In addition, alloys with better partial plasticity are also a kind of metal stamping materials, but this depends on whether the customer can request this material for processing.
Usually we divide the hardware into big and small hardware. Big hardware refers to steel plates, steel bars, flat iron, universal angle steel, channel iron, I-shaped iron and various types of steel materials, while small hardware mainly refers to construction hardware, tinplate, lock nails, iron wire, steel wire mesh, steel wire cutters , Household hardware, various tools, etc.
With regard to the nature and use of hardware, it should be divided into eight categories: steel materials, non-ferrous metal materials, mechanical parts, transmission equipment, auxiliary tools, work tools, construction hardware, and household hardware. There are many kinds of small hardware products and different specifications, which play an irreplaceable role in home decoration. Choosing good hardware accessories can make many decoration materials safer and more convenient to use.
