Description

Technical Field

[0001] The present application relates to the field of sheet metal stamping, and in particular to a sheet metal stamping support mechanism. Background Art

[0002] Sheet metal stamping is a common metalworking process used to process sheet metal into various parts and products. It usually involves placing the metal sheet on a stamping machine or punch press, and then using the die to apply high pressure to plastically deform the sheet to finally form the desired shape of the part or product.

[0003] Before stamping a sheet metal part, the stamping part needs to be stably placed inside the stamping die. However, due to its relatively thin thickness, the sheet metal part is easily bent by external forces. The two sides of the sheet metal part placed inside the stamping die will hang down along the die, which may cause a certain deformation of the sheet metal part as a whole during stamping, thereby affecting the overall shape of the sheet metal part and reducing the overall efficiency of the sheet metal part after stamping.

[0004] In view of the above-mentioned related technologies, the inventor believes that sheet metal parts have the defect of being easily bent and deformed during stamping. Therefore, a sheet metal stamping support mechanism is proposed to solve the above problem. Utility Model Content

Both sides of the top of the fixed base 1 are welded with fixed frames 4, and fixed rods 5 are symmetrically fixedly connected between the fixed frame 4 and the support platform 2. A plurality of No. 1 movable blocks 6 are sleeved on the outer surface of the fixed rod 5, and a No. 2 movable block 7 is movably installed on the outer surface of the fixed rod 5 near the fixed frame 4. A connecting rotating rod 10 is rotatably installed in the middle of the bottom end of the No. 1 movable block 6, and a first movable rod 11 is rotatably installed in the middle of the bottom end of the No. 2 movable block 7. Second movable rods 12 are rotatably installed at both sides of the upper surface of the fixed base 1 near the support platform 2, and the bottom ends of the first movable rod 11 and the second movable rod 12 are respectively rotatably connected to the top ends of a single connecting rotating rod 10, and a plurality of connecting rotating rods 10 are rotatably connected to each other. A rotating mechanism is also provided above the fixed base 1 for adjusting the No. 1 movable block 6 and the No. 2 movable block 7 to move.

[0020] By placing the sheet metal on the upper surface of the fixed mold 3 and supporting it with multiple support plates 9, the No. 2 movable block 7 is moved to drive the first movable rod 11 to rotate, and the first movable rod 11 drives multiple connecting rotating rods 10 to rotate synchronously, and the second movable rod 12 rotates synchronously with the connecting rotating rod 10, and then the movable No. 2 movable block 7 drives multiple No. 1 movable blocks 6 to move synchronously, which reflects the overall position adjustment effect of the No. 1 movable block 6 and the No. 2 movable block 7.

[0021] Reference Figure 1 and Figure 3 The rotating mechanism includes a threaded rod 13, which is rotatably mounted between the support platform 2 and the fixed frame 4.

A threaded hole is provided through the middle of one side of the second movable block 7. One side of the outer surface of the threaded rod 13 is located inside the threaded hole. The threaded rod 13 and the threaded hole are adapted to each other.

[0022] By starting the servo motor 14 to drive the threaded rod 13 to rotate, the threaded rod 13 drives the second movable block 7 to move along the outer surface of the fixed rod 5, and drives the support column 8 and the support plate 9 to move synchronously, reflecting the overall position adjustment effect of the second movable block 7.
