Description

Technical Field

[0001] The utility model relates to the technical field of cutter components, in particular to a cutter component. Background Art

[0002] The stamping sheet forming process is generally divided into several steps: drawing, trimming, shaping, and punching. The trimming process requires the removal of excess material from the drawing process, which is called waste. The waste needs to be discharged through the waste line. The size of the waste is limited by the size of the discharge port and the conveyor line. The function of the waste cutter is to cut large pieces of waste into small pieces to meet the size requirements when the waste is discharged. The existing waste cutting process uses a general waste knife that directly pulls and shears. There is also an improved type that pierces first and then cuts, which is called a separate waste knife.

[0003] However, although the general scrap cutter can cut the scrap, the gap between the lower cutter and the plate determines the process of pulling and tearing before cutting, which will produce a large amount of chips due to the second cutting. The chips flying into the mold will cause many pits and indentations on the plate, affecting the appearance quality of the stamped plate. The separated scrap cutter eliminates the gap between the lower cutter and the plate, pierces first and then shears, avoiding the second cutting, but the first piercing process is prone to condensation of cutting powder, thereby increasing the wear of the blade and indirectly causing the generation of new cutting powder.

[0004] Therefore, it is necessary to provide a new cutter assembly to solve the above technical problems. Utility Model Content

Specifically, when it is necessary to cut the waste material, the top surface of the waste material is closely attached to the upper blade 31 and the blade of the pressure knife 2. In fact, the pressure knife 2 needs to extend out of the groove, so that the elastic member 1 can be compressed when placing the waste material, so that the top surface of the waste material is closely attached to the upper blade 31 and the blade of the pressure knife 2, and then the bottom surface of the waste material is closely attached to the lower blade 41, and then the operator lifts the lower cutting knife 4, so that the lower cutting knife 4 cooperates with the upper cutting knife 3 to start shearing the waste material, push the waste material and the pressure knife 2 to rise, and compress the elastic member 1, so that the elastic member 1 is deformed until the waste material is completely cut off. After the waste material is cut off, the operator lifts the lower cutting knife 4 from The waste material is moved downward, so that the elastic member 1 will return to its original shape without being squeezed, and the restoring force generated will push the pressure knife 2 back to its original position and push out the cut waste material; through the above structure, the lower cutting knife 4 can be close to the bottom surface of the waste material, thereby avoiding vacuum cutting without support and pressure, and the pressure knife 2 is arranged to press the waste material to restrict its movement, avoiding the double cutting operation of tearing first and then cutting, and reducing the chips generated during cutting as much as possible. Reducing the chips can prevent the chips from splashing, thereby preventing the product from having defects due to the splash of chips, thereby improving the quality of the product.

[0030] See also Figure 1 In one embodiment, the press knife 2 is clearance-matched with the groove 33. The smaller the clearance between the press knife 2 and the groove 33, the blade of the press knife 2 and the upper blade 31 will form a complete plane, and no gap will appear, providing a complete support plane for the waste material, and no chips will remain in the gap, preventing damage to the press knife 2, and the clearance fit can also ensure that the press knife 2 can slide in the groove 33.
