Use of bending machine molds

Bending machine molds have L-type, R-type, U-type, Z-type and other types of bending, the main use of the upper die has 90 °, 88 °, 45 °, 30 °, 20 °, 15 ° and other different angles. The lower die has double and single slots with different slot widths from 4 to 18V, and there are also R lower dies, acute angle lower dies, flattening dies and so on. The upper and lower molds are divided into segments and whole: the upper mold segments are generally 300mm, 200mm, 100mm, 100mm, 50mm, 40mm, 20mm, 15mm, 10mm, and the whole is 835mm. the lower mold is generally divided into 400mm, 200mm, 100mm, 50mm, 40mm, 20mm, 15mm, 10mm, and the whole is 835mm.

  1. bending machine mold is made of high-quality steel by special heat treatment, with high hardness, not easy to wear, withstand pressure, etc., but each set of molds have it to withstand the limit of pressure: tons / m, so in the use of molds should be the correct choice of the length of the mold, i.e., how much pressure per meter, never more than the mold marked by the pressure, which is very important to keep in mind, hope that everyone.
  2. In order not to damage the mold, we stipulate in the origin, must use more than 300mm length of the upper and lower mold to the origin. The same height of the upper and lower molds can be used only after the origin is corrected. It is strictly prohibited to use a small split die for the origin, and the origin must be according to the origin pressure of the AMADA machine as a standard, which should not exceed 7 tons for 80T, 10 tons for 100T, and 15 tons for 200T.
  3. When using molds, because the height of various molds is not the same, so when choosing molds on a machine, only the same height of the molds can be used, not different heights of the molds.

4 in the use of molds, according to the metal sheet material hardness, thickness, length to choose the appropriate upper and lower mold, the lower mold I generally use the lower mold according to the standard 5 ~ 6T, the length should be longer than the sheet material, when the harder the material, the greater the thickness of the material, the application of the slot wider than a little bit of the lower mold.

5 in the bending of sharp corners, or press the dead center, should be selected 30 degrees on the first bending of sharp corners, and then press the dead center. In the bending R corner, should be selected R upper mold and R lower mold.

  1. in bending longer workpieces, it is best not to use segmented molds to reduce the knife indentation, and it is best to use a single slot, because a single slot of the lower mold V groove angle R is not easy to produce bending indentation.
  2. In the selection of the upper mold, the specific use of which the upper mold, we should understand all the parameters of the mold, and then according to the shape of the product to be formed, to decide what to use the upper mold.

8 in the bending hardness of special hard or plate material is too thick products, it is strictly prohibited to use 103 # and 116 # on the mold, easy to damage the mold, not allowed to use the mold to bend steel or other cylindrical products.

9 in the use of molds, should be clear-headed, in the machine after the origin of the upper and lower mold should be locked, do not let the mold fall, injuries or injuries to the mold, the process of operation, pressurization should pay attention to, can not add too much pressure, pay attention to the screen to show the change in data.

  1. After using the mold should be put back on the mold rack in time, and put it according to the logo, often clean the dust on the mold, and coated with antirust oil, so as not to rust, reduce the precision of the mold.
