Aluminum heatshields not only protect against heat, they also reduce vehicle noise emissions. In this photo from Autoneum, we see a perfect application where selecting the right lubricant for stamping the aluminum will help ensure maximum performance in the press, as well as compatibility with the aluminum alloy at hand, and ease post-processing work such as welding. Aluminum use in metalforming applications continues to rise, and not just by automotive-parts makers. Selecting the right lubricant for aluminum stamping will help ensure maximum performance in the press, as well as compatibility with the aluminum alloy at hand, and ease post-processing work such as welding. For many years, straight oils, mineral-based soluble oils or emulsions, and dry-film lubricants ruled the aluminum-stamping market with respect to performance.
The vegetable oils used are blends of assorted C18 to C24 hydrocarbons with varying degrees of saturation. Automotive-parts suppliers that typically deep-draw aluminum shown here using a chlorinated-paraffin straight oil can switch to a chlorine-free soluble oil and eliminate tearing and galling concerns while reducing lubricant use and cost.

- Taking the HSE impact into account is an integral part of the technical specifications for our lubricants.
- When ETNA started operations in , we began providing our drawing and stamping fluids and lubricants to produce shell cases for ammunition.
Lubrication plays an important role in sheet metal forming by affecting metal flow and reducing the possibility of fracture during forming. A number of tests are used to evaluate lubricant performance, stampkng the strip draw test, the twist compression test, and the cup drawing test. The cup drawing test CDT does a good job emulating the pressure, velocity, and temperature conditions of a stamping operation. At the Hyson facility, researchers from the Center for Precision Forming tested 24 lubricants from four different companies.
The schematic of a CDT is shown in Figure 1. The cup is always drawn to the same depth of 80 millimeters. During the test, the dtawing is not drawn completely, and some flange remains at the end of the operation. The perimeter of the flange is measured for each specimen.
The length of the flange perimeter is an indication of the lubricant performance. Chicago drawing stamping lubricants smaller the perimeter for a given blank holder force BHFthe better Chicago drawing stamping lubricants lubricant and the lower the coefficient of friction COF. The lower the maximum forming load, the better the lubricant. During this set of experiments, a total of samples blanks of 12 inches diameter were used, and four different variables were measured to evaluate the lubricant performance:.
While some materials such as mild steel may not show a significant temperature increase during forming, others such as AHSS may wtamping temperatures higher than degrees F in high-volume production. Because the blank generates Chicago drawing stamping lubricants, the tooling might expand thermally, reducing the clearance between the punch and the die and creating undesirable forming conditions.
Therefore, in these cases, selecting a lubricant that performs well at high temperatures and also has a cooling effect is very important. The temperature of the drawn cup was recorded using the infrared camera, which was triggered manually as soon as the cup was visible see Figure 2.
While the part surface can lose heat when the cup is ejected, this measurement gives a good estimation of the temperature generated during forming. The forming speed was kept constant during the experiments; however, the BHF was selected according to the blank material wtamping thickness. In ranking the lubricants, researchers used the average temperature and the average flange perimeter as the main parameters.
For each material, the best five lubricants were selected based on average flange perimeter and average temperature. Lubricants X and J Chicago drawing stamping lubricants performed best for all the materials tested. Figure 1 Schematic Meet for sex in texola oklahoma deep-drawing tool used in this study.
The experimental parameters, such as forming speed and draw depth, Chicago drawing stamping lubricants in the experiments were reproduced in the simulations. Using this methodology it is possible to estimate the COF stampjng the lubricant by matching draiwng flange perimeter measured on the experimental samples with the corresponding values obtained through FE simulation see Figure 4. As a comparison, the COF estimated for the lubricant E shown in Figure 3 was used in the simulation to predict temperatures.
Figure 4 also shows that the maximum temperatures estimated using simulations were close to the experimental values for the tested case. Figure 5 shows that the highest temperature caused Chicago drawing stamping lubricants material deformation occurred around the die corner radius, as estimated using FE simulation.
Conversely, the temperature in the cup near the punch corner radius did not show any significant change in temperature, since the deformation in that region was small.

In this case, the parts did not have to be washed before assembly. Waterjet Cutting. Remember Me. Tube and Pipe Fabrication. These compositions also help reduce the impact of the aluminum-oxide layer on the surface of the substrate, which naturally adds some abrasiveness. OHSAS Provide Feedback. However, during stamping of thin-gauge materials at high rates, the die and punch become warm, which can change the properties and behavior of the lubricant. We should advance beyond just looking for the best forming lubricant that performs well during secondary processing. Meiler and H.
