  • This breaking apparatus 1 includes, as its main components, a frame 2 composed of side plates 2a and 2b, and a span plate 2c and having open top and bottom, a fixed cutter unit 4 (one cutter unit) provided in the frame 2, a movable cutter unit 5 (the other cutter unit) which faces the fixed cutter unit 4, a cylinder 6 (a driving means; hereinafter referred to as "cylinder 6"), such as hydraulic pressure, which advances and retreats the movable cutter unit 5, and a damper 7.
  • all angles of the fixed cutters 43 are formed in the shape of a curved surface, and a connecting part 44 between the fixed cutter plate 42 and each of the fixed cutters 43 is formed in the shape of a curved surface. Loss (chipping and/or breaking) can be avoided by forming the angles and connecting parts in the shape of a curved surface as such.
  • the fact that the loss of high-manganese steel has an adverse effect on a regenerated casting, and for example, causes quality deterioration can be mentioned as the above reason.
  • the fixed cutter 43 contains C: 1.0 to 1.6 wt% of carbon, Si: 0.25 to 0.8 wt% of silicon, and Mn: 10 to 15 wt% of manganese as its chief constituent elements.
  • all angles of the movable cutters 53 are formed in the shape of a curved surface, and a connecting part 54 between the movable cutter plate 52 and each of the movable cutters 53 is formed in the shape of a curved surface. Loss (chipping and/or breaking) can be avoided by forming the angles and connecting parts in the shape of a curved surface as such.
  • the fact that the loss of high-manganese steel has an adverse effect on a regenerated casting, and for example, causes quality deterioration can be mentioned as the above reason.
  • the movable cutter 53 contains C: 1.0 to 1.6 wt% of carbon, Si: 0.25 to 0.8 wt% of silicon, and Mn: 10 to 15 wt% of manganese as its chief constituent elements.
  • the basal ridge has features of performing prevention of scattering of a regenerated casting W3, and pressing (pressing stress) of the regenerated casting W3 existing in the breaking apparatus 1 (downward) towards a discharge port 11 of the breaking apparatus 1. Moreover, the basal ridge is effective for reinforcement, etc. of the movable cutters 53.
  • FIG. 1 first, a method of enhancing the hardness of the fixed cutters 43 of the fixed cutter unit 4 and the movable cutters 53 of the movable cutter unit 5 will be described.
  • a raw material W is charged from above a substantially V-shaped charging opening 12 formed by the movable cutter plate 52 and movable cutters 53 of the movable cutter unit 5, and the fixed cutter plate 42 and the fixed cutters 43 of the fixed cutter unit 4.
  • breaking force As for the charged raw material (casting waste) W, when the movable cutter unit 5 advances along a circular arc locus with a lower pivot point 20 as a fulcrum, almost the whole pressing force of the cylinder 6 acts on a fulcrum shaft 21 above the movable cutters 53, and the movable cutters 53 advance along a circular arc locus, a strong crushing force and/or breaking force (referred to as "breaking force") is generated according to the principle of a lever above the discharge port 11 in the vicinity of the lower pivot point 20, thereby positively and smoothly cutting the charged raw material W between the movable cutters and their facing fixed cutters 43.
  • breaking is performed using fitting and/or pressing relationship between the movable cutters 53 and/or movable cutter plate 52, and the fixed cutters 43 and/or fixed cutter plate 42 (between both the cutters).
  • this breaking is surely performed with low pressure by a configuration of being movable with the pivot point 20 as a fulcrum and of being movable along a circular arc locus via the upper fulcrum shaft 21 and the upper cylinder 6, this is helpful and useful in miniaturizing the whole breaking apparatus 1 and reducing running cost.
  • the pivot point 20 has features that smooth movement as an annular metal and a fulcrum bearing, which are not shown, and load resistance, are ensured.
  • a broken regenerated cast product (regenerated casting W3) naturally drops towards the discharge port 11 via the surfaces of both the cutters and/or gaps therebetween sequentially.
  • the damper 7 catches a relatively slender raw material (long raw material W2) of the charged raw material W, which has dropped from between the fixed and movable cutters 43 and 53 (referred to as "between both the cutters"), whereby positive reception of the raw material W and/or long raw material W2 described below, and positive and efficient breaking thereof can be achieved. Also, when a predetermined load is applied to the damper 7, the damper is opened automatically.
  • the hardnesses of the movable cutters 53 and/or the movable cutter plate 52 and the fixed cutters 43 and/or the fixed cutter plate 42 are enhanced.
  • Such enhancement in hardness has the aforementioned features. That is, through crushing of a casting waste by the casting breaking apparatus 1, the hardness can be naturally enhanced during operation. Also, uniform and predetermined hardness can be ensured without requiring labor and/or skill. Moreover, operation can be simplified, and cost can be reduced.
  • the hardness of the movable cutters 53 and/or movable cutter plate 52, and the hardness of the fixed cutters 43 and/or fixed cutter plate 42 are fixed, the hardnesses are maintained.
  • the movable cutter unit 5 at an advancement limit retreats through extension and retraction of the piston rod 60 of the cylinder 6, and stops by the operation reaching a retreat limit as it is.
  • the movable cutter unit 5 advances, and repeats the same breaking operation as the aforementioned operation. That is, when a raw material W exists between both the cutters, advancement and retreat of the movable cutter unit 5 are repeated. Also, when any raw material W does not exist between both the cutters, a new raw material W is charged towards the charging opening 12 in a state of a retreat limit in principle similarly to the above.
  • the invention provides a cutter device mounted on a casting breaking apparatus which crushes and breaks (referred to as "break") casting wastes, such as gates, runners, weirs, and defective castings, and a method of enhancing the hardness of the cutter device.
  • break a casting breaking apparatus which crushes and breaks (referred to as "break") casting wastes, such as gates, runners, weirs, and defective castings, and a method of enhancing the hardness of the cutter device.
  • This makes it possible to eliminate a deposit operation after casting required to ensure the wear resistance of the fixed cutters and movable cutters. Also, labour and advanced skill required for welding and/or deposit operation can be eliminated. Moreover, operation can be simplified, and working hours can be shortened. Accordingly, there is a feature useful for the casting industry and the industrial field.
