Description

TECHNICAL FIELD

[0001] The utility model relates to a trimming die technical field, concretely is a trimming die of grass cutting disc. BACKGROUND

[0002] In the production of grass cutting disc, the metal plate is placed in the stretching die first, and the upper and lower templates in the stretching die will first clamp and fix the metal plate, and then the metal plate is stretched by the setting die to make the metal plate plastically deformed into the required grass cutting disc pattern. But this will cause a circle of edge to be left on the periphery of the grass cutting disc, which needs to be cut again using the trimming die. The existing trimming die sets a cutting groove on the base, and the cutting blade will be clamped in the cutting groove during trimming to avoid damage to the die base, but the edge of the cutting groove will be worn due to pressure, and in severe cases, it will also be damaged. If the entire base is replaced, the cost is large, and frequent replacement of the base will affect the precision of the die; during trimming, the cutting blade will be displaced due to insecure installation, causing the cutting blade to collide with the die, which will cause the blade to break and cause serious safety hazards.
