Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing, and in particular relates to a slanted push bending mechanism. Background Technology

[0002] Currently, the conventional bending method is a straight up-and-down bending structure. During the production process, the product surface is scratched, copper is exposed, and metal dust is wiped out. The bending tool needs to be cleaned regularly, resulting in low productivity and potential quality problems.

[0003] Comparing with Chinese Patent CN115401095A, a slanted push-type bending stamping die is disclosed, comprising: an upper die mechanism, including an upper die base, a stop plate, an upper stripper plate, an upper stripper plate pressure block, and an upper die inserter. The stop plate is located below the upper die base, the upper stripper plate is connected below the stop plate, the upper stripper plate pressure block is connected to the bottom surface of the stop plate and is located at one end of the upper stripper plate, the upper stripper plate pressure block has a first inclined surface, the upper die inserter is connected to the upper die base, the upper die inserter is located near the upper stripper plate pressure block, and the upper die inserter has a second inclined surface; and a lower die mechanism, including a lower pad plate and a lower template plate disposed on the lower pad plate, the product being placed on the lower template plate, a guide block disposed on the lower pad plate, the guide block having a third inclined surface, and a side push slider slidably connected to the guide block. Changing the angle of the side push slider not only compensates for the product appearance problems caused by the previous flattening structure, but also effectively reduces the lateral force during the forming process, thereby solving the problem of surface scratches on the product.

[0004] However, the aforementioned patented stamping bending force still has an angle with the bending surface, and cannot be completely perpendicular to the bending surface, thus failing to completely solve the problem of surface scratches on the product. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a slanted push bending mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A slanted push bending mechanism includes a pressure block, a lower bending blade disposed below the pressure block, a product placed between the pressure block and the lower bending blade, an upper bending blade disposed inside the pressure block, and a limiting groove obliquely disposed inside the pressure block. A bending blade slide block is slidably mounted in the limiting groove, the upper bending blade is mounted at the bottom end of the bending blade slide block, a limiting hole is disposed at the top of the bending blade slide block, and a wedge block is mounted on the bending blade slide block, the wedge block passing through the limiting hole and slidably connected to the bending blade slide block.

[0008] Further, the pressure block is provided with an avoiding hole near one side of the limiting sliding groove, the avoiding hole is vertically arranged to ensure the inclined wedge block to slide along the avoiding hole and avoid interference with the pressure block.

[0009] Further, the pressure block is elastically pressed on the product to facilitate stretching of the product during bending.

[0010] Compared with the prior art, the beneficial effects are:

[0011] The inclined wedge block pushes the folding knife sliding seat to drive the upper folding knife to move along the limiting sliding groove and vertically apply force on the bending surface of the product, so that the upper folding knife and the product are relatively free of friction during bending, the surface of the product is not scratched and metal chips are not dropped after bending, the bending tool does not need to be cleaned during production, the downtime and cleaning time are greatly saved, the efficiency is improved, the risk is reduced, and the rebound angle of the product after bending is small and the bending size is more stable.
