Stamped and bent parts

In stamping and forming technology Stamped parts and Stamped and bent parts made of metal in any desired shape. They are among the components that are most frequently used across industries. This includes simple metal moldings, Spring clips or Pipe clamps , Spring clips or Retaining springs that fix the brake pads in cars and trucks, for example. There are also electrically conductive ones Spring contacts as well as medically pure components with a flawless surface that are specially hardened and independent of temperature. To produce them, different punching techniques combined with different forming techniques are used.

Stamping and forming techniques at a glance:

Stamping technology

With conventional punching of metal, punching machines and punching tools are required in the desired dimensions of the required components. The tool consists of an upper tool, the so-called punch, and the die, the lower tool. In order to achieve optimal results, the upper and lower tools must fit together perfectly. This is how the process works: The punching machine is equipped with the desired punching tool. The punch is above, the die below the flat steel or sheet metal. Depending on the thickness of the material, the punch pushes through the component with a cutting force of up to 250 tons. The die ensures that it is not bent in the process. This non-cutting cutting process is also called shear cutting.

Forming technology

In the stamping and bending technology, further processing steps from the forming technology are used in addition to stamping. In addition to the pure multi-stage forming, this includes the following processes:

  • Pressing in – for example of threaded bolts
  • Thread forming and thread cutting
  • welding
  • Rivets
  • Screw
  • Assemble
  • Assembly production

The stamping and bending process is particularly suitable for large quantities. In addition, the method is cost-efficient, precise and at the same time more energy-saving than, for example, with Laser cutting because the material does not have to be melted. Mainly automatic punching and bending machines, freely programmable bending punches and punching tools made of powder steel or hard metal in the form of strip material are used. This is made of various steel materials ready to fall. The special feature: The punching tools are still wear-resistant even after millions of parts.

Advantages of stamping and bending technology compared to other production processes:

  • Fast and energy-saving process because the material is not melted like with laser cutting.
  • No thermal change, as the processing is purely mechanical.
  • There are many Forming techniques possible, also in one operation.
  • Stamped parts and stamped bent parts are produced in a short time with consistently high quality.

Disadvantage of the stamping and bending technology compared to other production processes:

  • Not every shape and material thickness can be punched with this technique. Then the stamped and stamped bent parts are cut using the laser cutting process and post-processed using various forming techniques.
  • Uneconomical with small quantities

From what quantity are stamped parts and stamped bent parts worthwhile?

Stamped and stamped bent parts can be produced from a production quantity of 2,000 pieces manufacture cost-effectively. With sample parts, small and medium quantities, the production of punching tools and progressive tools is therefore not worthwhile. Such parts become cheaper with laser cutting or processed by bending using automatic bending machines and other forming techniques.

The production range at Gutekunst Formfedern

Gutekunst Formfedern manufactures stamped parts and Flat springs on automatic punching machines with a pressing force of eight to 63 tons. Material thicknesses of 0.05 to 3.0 millimeters are processed with a maximum bandwidth of 150 millimeters. Stamped parts can be omitted different types of spring steel such as C75S, C100S, stainless steel 1.4310, 1.4301, aluminum, non-ferrous metals such as copper CuSn6, CuZn37 and CuBe2, bronze, brass and various special alloys. Various punching machines and eccentric presses are used depending on the production volume and processing method.

Technical springs - Gutekunst FormfedernThe stamped and bent parts from Gutekunst include simple metal moldings, Spring clips , Spring clips , Form springs , Pipe clamps , Retaining springs as well as electrically conductive Spring contacts or even medically pure components with a flawless surface. Depending on the requirements, Gutekunst Formfedern offers almost all qualities of metal materials: punched, lasered, bent, folded, welded, riveted, screwed or processed into complex assemblies – regardless of whether flat steel, sheet metal or split strip.

Materials such as steels, stainless steels, aluminum or non-ferrous metals such as copper, bronze, brass and beryllium copper (CuBe) as well as various special alloys are often processed by Gutekunst form springs into stamped and bent parts. Customers receive these in larger quantities with progressive tools in one operation. Regardless of which material is required: the production spectrum at Gutekunst Formfedern GmbH includes material thicknesses from 0.05 to 3.0 millimeters, belt widths from 1.0 to 150 millimeters, plate sizes up to 1,500 x 2,500 millimeters and a pressing force of 180 to 800 kilonewtons .

Additional surface treatments

Gutekunst can also use a subsequent surface treatment such as vibratory grinding, galvanizing, silvering, gold plating, burnishing, hydrogen brittle or etching with additional properties.
