Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, a preferred embodiment of the present invention is a novel included angle trimming apparatus, which includes a first trimming blade 1 and a second trimming blade 2, wherein the first trimming blade 1 is obliquely arranged relative to the second trimming blade 2; the first trimming cutter 1 is provided with a material ejecting mechanism 3 and a notch 4, and the notch 4 is arranged at the upper end of the material ejecting mechanism 3; the second trimming cutter 2 is provided with a fillet 5, the fillet 5 is connected with the material ejecting mechanism on the first trimming cutter 1 through the edge of the mold 6, the included angle cutter changing position is changed from cutting to full tearing, secondary recutting is not generated, the abrasion of a cutter edge and the follow-up maintenance difficulty are reduced, and therefore the maintenance cost is reduced.
As a preferred embodiment of the present invention, it may also have the following additional technical features: the material ejecting mechanism 3 comprises a boss which is arranged below the notch 4 and integrally connected and formed with the first trimming cutter 1, and the height of the boss is 15-20mm, so that waste materials can be torn according to the edge of the die and abut against the trimming contour of the second trimming cutter 2, and secondary recutting and material scrap generation are avoided.
In this embodiment, the notch 4 is arranged on the blade edge of the first deburring tool 1 and located at the tool intersection region of the first deburring tool 1 and the second deburring tool 2, and the length of the notch is 5 mm.
In this embodiment, the fillet 5 is located at the blade tip of the second trimming tool 2, so that the tear is continuous and larger after the second trimming tool 2 is cut in (the tear is insufficient due to the fact that the blade tip directly tears the material and the plate material is easily punctured), and the tear is smoother.
The utility model discloses a theory of operation: make fillet 5 of R3 on the knife tip of second deburring cutter 2 let it cut earlier the back tear the material and last and bigger (the knife tip directly tears the material and easily puncture the sheet material and lead to tearing the material inadequately), make 15 ~ 20mm liftout boss at first deburring cutter simultaneously, let the first deburring cutter 1 of back cutter also have sufficient tear the material in handing over the sword region, for thoroughly preventing first deburring cutter 1 in handing over sword region repeated cutting, empty 5 mm's notch 4 in the 3 districts of the sword blade of first deburring cutter 1, the utility model discloses a contained angle deburring device is verified through batch production, and this position scrap is eliminated completely.
Therefore, the utility model discloses a contained angle deburring device can be applied to in the planking spare moulds such as common side wall, fender, suitcase, because there is serious material bits phenomenon in this type of structure secondary repeated cutting. The improved included angle cutter-crossing position is changed from cutting to full tearing through rectification, secondary repeated cutting is not generated, abrasion of a cutter edge is reduced, maintenance cost is reduced, and follow-up maintenance difficulty is reduced.
