Description

[0001] The utility model relates to a trimming die, in particular to a trimming die for processing thin parts, belonging to the technical field of trimming dies. Background Art

[0002] Parts refer to the inseparable individual parts that make up machinery and machines. Their manufacturing process generally does not require assembly steps, such as bushings, bearings, nuts, crankshafts, blades, gears, cams, connecting rod bodies, connecting rod heads, etc. Parts are the basic units in the machinery manufacturing process. When processing some thin parts with edges and corners, it is usually necessary to use a trimming die for thin parts processing to die-cut the edges and corners of the product.

[0003] Among them, a trimming die with the application number "CN202020942761.X" is provided with a trimming die knife matched with the shape of the corner of the punch on the trimming die rod. When die-cutting the product, it has the characteristics of high precision, good flatness and beautiful product. Further search found that a trimming die with the application number "CN201420080439.5" before trimming, the pressing punch and the trimming fixed punch complete the positioning of the forging, and then the trimming is performed, which plays a good correction role. The trimming movable die is located above the trimming fixed punch. After the trimming is completed, the forging is still on the trimming fixed punch, without falling process, avoiding bumps and scratches. After the trimming is completed, the trimming movable die moves up and separates from the forging to avoid annealing of the trimming movable die blade due to huge heat, thereby improving the service life of the trimming movable die.

[0004] However, the above two types of trimming dies still have certain shortcomings when in use. After the trimming dies have worked for a long time, a large amount of cutting debris is easily adsorbed and left on the top of the lower die and the trimming die knife. If not cleaned in time, it will easily affect the smoothness of the next cutting, and at the same time it will reduce the service life of the trimming die knife, and it is not convenient to provide a better cutting debris cleaning function.
