Chibi and medium hardness metal suitable Stamped metal Avoid cracks during stamping.

3. Bending

Bending refers to the process of bending a metal plate into a desired shape or angle through a mold. This process applies bending force to the metal plate, causing the metal plate to bend and deform under the action of the mold. Bending is one of the common processes in metal stamping. It is widely used to manufacture a variety of parts and products such as boxes, shells, brackets, etc. to provide the shape and structure required for metal products.

4. Extend

Also known as drawing or calendar, it is a stamping treatment that uses a mold to sprint into an open hollow part to a flat blank. Thin-walled parts can be made in cylindrical, stepped, conical, spherical, box-shaped and other irregular shapes.

5. Graphics

Brand is creationMetal stamps, pattern or texture on the hardware surface. For example, add decorative features, logos,Metal stamps, or the texture of components commonly found in coins and jewelry.

6. To-do Items

One of the most basic forms of metal stamping is to use machining tools to punch holes in metal plates to create multiple small hollow areas. The punching material produced during the entire processing process is discarded.

7. Transmission

This is a plastic processing method that bends the edges of the sheet blank, or material along a narrow area of ​​the precast hole edge on the blank, along a curve or straight line along a vertical edge. It is mainly used to strengthen the edges of parts, remove the trimming edges, and assemble them with other parts. Connecting part.

8. Door

The main feature of the groove is to transfer a small V-shaped notch or groove fromMetal pedal. Usually, two pieces of metal need to be interlocked or connected, such as creating labels and notches for components.

What is the type of metal stamping machine?

Mechanical brushing machine

Mechanical pressing mainly uses a motor connected to a mechanical flywheel to transmit and store energy. The rotation of the motor drives the flywheel to rotate, releasing the energy in the flywheel during the stamping process, driving the slider (or punching) to move upward, thereby realizing the stamping treatment of metal materials.
Mechanical stamping machines have the advantages of simple structure, low manufacturing cost and ease of maintenance. They come in a variety of punch sizes, ranging from a few millimeters to hundreds of millimeters, and at different pressure speeds, usually between 20 and 1,500 rods per minute. These presses range in size from 20 to 6,000 tons and are suitable for progressive and transfer stamping in high-volume production.

Hydraulic Publishing House

Hydraulic presses use hydraulic systems to apply pressure to the material. The hydraulic system converts the pressure of liquid (usually oil) into mechanical energy through a hydraulic pump, which drives the slider to move up and down. The hydraulic piston replaces the fluid with a force level proportional to the diameter of the piston head, allowing advanced control of the pressure amount.
Hydraulic presses have the advantages of stable pressure, adjustable stroke and speed, and can provide full power at any time during a stroke. These presses usually range in size from 20 to 10,000 tonnes, with stroke sizes ranging from about 10 to 800mm. Hydraulic presses are often used in smaller production operations to create more complex, deeper stamped parts than mechanical presses.

Mechanical servo stamping machine

Mechanical servo stamping machines use high-capacity motors instead of flywheels and precisely control the motor's speed and torque through a servo control system to accurately control sliding motion.
Mechanical servo presses have the advantages of stroke, sliding position and movement, and the speed can all be controlled and programmed. They can be made at a more complex stamping speed faster than hydraulic presses and are the most expensive pressure of the three types.

What are common metal stamping materials?

Aluminum and aluminum alloys

Aluminum is a non-productive metal that is relatively cheap and has an excellent strength to weight ratio, making the parts durable, sturdy and lightweight. At the same time, aluminum is corrosion resistant and non-toxic, and does not require coating during finishing, although it can smoke oxidize to enhance its appearance and increase its corrosion resistance. Usually used as a device component during stamping.

Carbon steel/stainless steel

Stainless steel is a ferrous metal that contains a lot of chromium, molybdenum and nickel. It is corrosion-resistant, non-magnetic, has good wear resistance, does not require electroplating, and can be heat-treated. Carbon steel and stainless steel stamping processes are usually used to manufacture equipment casing, structural parts, casing, etc. However, due to their strong rigidity, imprint oils are often used to improve the process.

Titanium alloy

Titanium alloy stamps are mainly used in large equipment, aircraft, ships and other products that require high strength and light weight. Due to the difficulty of the process, special stamping oil must be used to improve the process.

Copper and copper alloys

Copper is easy to form and is ideal for rapid production of one-piece, seamless components and is compatible with the cold formation process. Copper is a low-maintenance and durable metal that resists corrosion and has natural hygiene properties. Brass alloys retain many of the beneficial properties of copper, such as smooth surfaces, corrosion resistance and electrical conductivity. Therefore, it is often used as a device component during stamping.
