Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a product punching mechanism with concave ribs on the side wall. Background Art

[0002] Traditional products with ribs on the side walls must be pressed from the side due to the presence of the ribs. The side holes are punched by using sliders on both sides or the die using self-sliders. For example, publication number CN218574758U discloses a stamping die with synchronized side punching and hole turning. Drive plates are provided on both sides of the die, which are respectively used to push a first slider with a punching die and a second slider with a punch. When stripping, the product does not move on the first lower template, and the punching die supports the product to strip it out, thereby achieving product stripping.

[0003] This type of mechanism has a complex structure, low precision, large space occupation and high cost. Since the sliders on both sides of this mechanism are in motion with a large gap, there are many unstable factors in the production process, resulting in poor product production, such as large burrs, cracked blades, gap deviation and other problems. When stripping, the product is unstable on the lower template and is easy to fall. Summary of the invention

[0004] The utility model provides a product punching mechanism with concave ribs on the side wall to overcome the shortcomings of the prior art.

[0006] A knife support seat is connected above the lower die seat, and a knife insert is fixed on one side of the knife support seat. The knife insert supports one side of the driving block when the die is closed.

[0007] A stripping plate is connected to the lower part of the upper die seat through an upper die nitrogen spring, and the lower end of the stripping plate is connected to a stripping plate insert, which presses downward on the material.

[0008] The upper end of the upper die seat is connected to the nitrogen spring seat, and the top of the upper die nitrogen spring is installed in the nitrogen spring seat.

[0009] A punch pad is fixed in the lower die slide block, a punch fixing plate is fixed on one side of the punch pad, and the punch is fixed in the punch fixing plate.

[0014] A second self-lubricating plate is provided between the lower die slide block and the lower die seat.

[0015] Compared with the prior art, the utility model uses the guide rod and the nitrogen spring to link the floating block with the lower mold slider to push the product, thereby realizing free stripping of the product and facilitating the removal of the product after stripping. The guide rod pushing structure below the floating block is arranged in the lower mold plate to save mold space. BRIEF DESCRIPTION OF THE DRAWINGS
