Description

Technical Field

[0001] This utility model relates to the technical field of blank flash punching device, and in particular to a flash punching device for lightweight connecting rod blanks of automobile engines. Background Technology

[0002] As a core transmission component between the piston and crankshaft, the connecting rod of an automotive engine must withstand alternating loads under high temperature and pressure. Its manufacturing precision directly affects the engine's lifespan and fuel efficiency. Lightweight connecting rods (such as those made of aluminum alloy, titanium alloy, or with a lattice structure design) can significantly reduce engine weight and improve fuel efficiency and power response. However, lightweight materials produce tough "flash" (a thin layer of residual metal at the edge of the blank) during the forging stage. If not effectively removed, this can affect precision and performance. Therefore, a blank flash removal device is needed to solve this problem.

[0003] For example, in a prior art represented by application number CN202222575849.4, the main structure includes a workbench, a rotating disk rotatably mounted on the top of the workbench, a placement plate fixedly mounted on the top of the rotating disk, a movable plate at one end of the top of the workbench, and support columns fixedly mounted at both ends of the movable plate. In this invention, when punching round materials, the material can be placed on top of the placement plate, and then a second cutting blade is installed at the bottom of the first cutting blade. A cylinder drives the cutting frame and the first cutting blade downwards, which in turn drives the second cutting blade downwards. After the second cutting strip penetrates the material, a second motor drives the placement plate to rotate, thereby causing the material to rotate, facilitating the cutting of round materials and ensuring a more comprehensive cut. Adjusting the position of the cutting frame allows for the cutting of materials of different sizes.

[0004] During use, it was found that the existing blank flash punching device is inconvenient to transmit the connecting rod, and the manual punching alignment speed is slow, resulting in reduced punching efficiency. Therefore, there is an urgent need for a lightweight connecting rod blank flash punching device for automobile engines. Utility Model Content
