specific Embodiment approach 1

[0028] Specific implementation mode one: combine Figure 4-Figure 9 Illustrate, a kind of metal sheet metal part forming method that adopts multi-layer combined punch of this embodiment is realized according to the following steps:

[0029] Step 1, placing the blank 1 to be formed on the forming die 2 and positioning it;

[0030] Step 2, combining a plurality of plate-shaped molds 3-1 into a multi-layer combined punch 3 and positioning it at a suitable position above the blank 1;

[0031] Step 3, using the drive wheel 4 to drive the multi-layer combination punch 3, so that the multi-layer combination punch 3 gradually acts on the blank 1;

[0032] Step 4: After the blank 1 is completely fitted into the cavity of the forming die 2, the final sheet metal part 5 is obtained;

[0033] Step 5, remove the driving wheel 4 and the multi-layer combination punch 3, and remove the formed sheet metal part 5 from the forming die 2.

specific Embodiment approach 2

[0034] Specific implementation mode two: combination Figure 4 and Figure 5 Explain that the difference between this embodiment and the specific embodiment one is: the cavity of the forming die 2 in the step one is a circular or oval shape with a regular shape; the multilayer combined punch 3 in the step two is made of multilayer The plate mold 3-1 of about 20-50mm is formed, and the height and thickness of each plate mold 3-1 are identical and its bottom is all in contact with the upper surface of original blank 1 in initial state; In the step 3, the driving of driving wheel 4 is more The surface contour shape of the layer combination punch 3 is the same regular shape as the cavity of the die 2, and the driving wheel 4 rotates along the upper rotating shaft. Other steps and parameters are the same as in the first embodiment.

[0035] The beneficial effect of this embodiment is: since the multi-layer combination punch 3 is composed of plate-shaped molds of the same height a...

specific Embodiment approach 3

[0036] Specific implementation mode three: combination Figure 7 Explain that the difference between this embodiment and the specific embodiment one or two is: the forming die 2 in step one is an irregular shape, and the depth of the concave mold cavity changes irregularly; the multi-layer combined punch 3 in step two is It consists of multi-layer plate-shaped molds 3-1 with a thickness of 20-50mm. The height and thickness of each plate-shaped mold 3-1 are different, and the bottom of each plate-shaped mold 3-1 is in the initial state. Contact; in step 3, the surface profile of the drive wheel 4 driving the multi-layer combination punch 3 is circular, and the drive wheel 4 rotates along the upper rotation axis. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

[0037] The beneficial effect of this embodiment is: since the height and thickness of each plate-shaped mold adopted in step 2 are different, it is possible to obtain a punch shape that...

Abstract

The invention discloses a sheet metal part forming method with a multi-layer combined male die adopted, and relates to a sheet metal part forming method. The sheet metal part forming method with the multi-layer combined male die adopted is used for solving the problem that in the existing stamping forming process of sheet metal parts, because an integral male die is adopted, various quality defects are prone to appearing because of unreasonable contact and action between the male die and an original slab. The forming method comprises the steps of firstly, placing a slab to be formed on a forming die and carrying out positioning; secondly, combining multiple platy dies into the multi-layer combined male die and positioning the male die to the appropriate position above the slab; thirdly, utilizing a driving wheel to drive the multi-layer combined male die to make the multi-layer combined male die act on the slab gradually; fourthly, obtaining the final sheet metal part after the slab iscompletely attached to a cavity of a female die; and fifthly, removing the driving wheel and the multi-layer combined male die, and taking the formed sheet metal part down from the forming die. Withthe sheet metal part forming method with the multi-layer combined male die adopted, the uniformity of deformation in various areas on the slab can be improved, and the stability of a material formingprocess is improved.

Description

technical field [0001] The invention relates to a method for forming a metal sheet metal part, in particular to a method for forming a metal sheet metal part using a multi-layer combined punch. Background technique [0002] Metal sheet metal parts are widely used in industrial fields such as automobiles, high-speed rail, and aerospace, and are also very common in daily life, such as kitchen utensils, sanitary ware, etc. With the gradual improvement of the requirements for the structure and function of sheet metal parts in the above application fields, sheet metal parts become more and more complex. These structures can no longer adopt the traditional scheme of forming small pieces into small pieces and then combining them into a whole through welding and riveting. Instead, they need to be made into a whole as much as possible at one time, otherwise the design requirements of the product will not be met. [0003] At present, the most important forming method of metal sheet m...
