It is desirable to set it twice or more (in the left-right direction). Further, it is desirable that the width (left and right direction) of the end-side inclined band 53 is at least twice the width (left and right direction) of the inclined band 43 of the angled blade portion 40. Thus, even if it is a case where the half-divided angle blade part 50 divided | segmented into the end side is arrange | positioned by setting it as the width more than twice, sufficient intensity | strength can be provided.

  Moreover, in each figure, the width | variety (up-down direction) of the horizontal band 51b of the top T-shaped band 51 of the half angled blade part 50 is the width of the horizontal band 41b of the top cross band 41 of the angle blade part 40 ( The width of the band 51b in the left-right direction of the top T-shaped band 51 of the half-crested angled blade part 50 is equal to the width of the band 41b in the left-right direction of the top cross band 41 of the angled blade part 40.

  The material of the base material portion and the blade portion constituting the fixed blade plate and the movable blade plate of the present invention is characterized by being made of high manganese cast steel. As the high manganese cast steel is used, work hardening occurs, which is hardened one after another from the used part. That is, although the initial hardness is low, it is hardened from the surface by an impact applied to the surface, and the wear resistance is greatly improved, and the life of the blade plate is greatly increased. Specifically, the hardness after work hardening of the fixed blade plate 4 and the movable blade plate 5 is HRC 40 to 50 or more. Therefore, the blade plate of the present invention is mainly useful for hard crushing (hard cutting, hard cutting) having characteristics such as hard and thick, such as ductile cast iron (FCD material). ) It is also useful for crushing (cutting, breaking) cast iron (FC material).

  In addition, as other materials of the base material parts 4a and 5a and the blade part constituting the fixed blade plate 4 and the movable blade plate 5, for example, carbon steel for machine structure (SC), alloy steel for machine structure (SCM, etc.) Special steels such as the above, ordinary cast steel, and alloy castings based on FCD.

  A bolt hole 6 (female screw hole) into which a bolt for attaching the blade plate is screwed is formed in the base material portion of the fixed blade plate 4 and the movable blade plate 5. The bolt hole 6 is generally formed using a machine tool such as a commercially available machining center (not shown). For example, a bolt hole 6 machining tool is attached to the spindle of the machining center, and the bolt hole 6 is formed by rotating this tool. In the case of the fixed blade plate 4, the bolt holes 6 are provided on one or more of the front surface 4 a 1, the back surface 4 a 2, the flat surface 4 a 3, the bottom surface 4 a 4, the left side surface 4 a 5, and the right side surface 4 a 6 of the base material part 4 a.

  An example of a method for forming the bolt hole 6 is as follows. Here, the fixed blade plate 4 will be described. First, a predetermined portion of the fixed blade plate 4, for example, a surface or the like of the base material part 4a, which is the mounting surface, is drilled on one or more of the front surface 4a1, the back surface 4a2, the flat surface 4a3, the bottom surface 4a4, the left side surface 4a5, and the right side surface 4a6. Drill a pilot hole. Then, a screw hole is formed by forming a screw groove on the inner wall surface of the drilled pilot hole using a tap or the like.

  The pilot hole is formed to have an inner diameter smaller than the outer diameter of the threaded portion of the tap, and by inserting the tap while rotating, the inner wall surface of the pilot hole is cut to form a bolt groove, and the bolt hole 6 Is processed. That is, a lower screw (a lower hole, an inner diameter) having a diameter smaller than that of the bolt is cut with a drill or the like, and the bolt hole 6 is cut along the lower screw. For example, when the bolt hole 6 is formed using a tap, a hole having a lower diameter (minimum diameter) is first drilled with a drill or the like, and the bolt hole 6 is formed while screwing the tap into the lower hole.

  The machining center utilizes a control device that controls the driving of the machining center and the spindle according to the bolt hole 6 formation program. Specifically, according to the bolt hole 6 formation procedure defined in advance by the bolt hole 6 formation program, the position between the special tool for machining the bolt hole 6, the fixed blade plate 4, and the movable blade plate 5 and Perform speed control. Further, the machining center performs control of the rotational speed of the spindle by decoding the rotational speed of the spindle motor, for example, in the bolt hole 6 formation program.

  As a specific machining method, for example, a special tool (super steel thread cutting) mounted on a spindle such as a machining center capable of three-axis control of the X-axis (vertical axis), Y-axis (horizontal axis), and Z-axis (oblique axis). For example, there is a method of forming a female screw hole using a helical feed (arc) function of a machining center or the like. In this method, first, a pilot hole is drilled on one or more of the front surface 4a1, the back surface 4a2, the flat surface 4a3, the bottom surface 4a4, the left side surface 4a5, and the right side surface 4a6 of the base material part 4a, which is the mounting surface.

  Then, while rotating (arrow) the main spindle of the machining center on which a special tool (super steel thread cutting tip or the like) is mounted, this main spindle is helically fed in the Z-axis direction to cut the female thread groove on the inner peripheral surface of the prepared hole. For example, the female thread groove is formed by being helically fed so as to advance one pitch for each revolution.

  Further, by using a tap with a drill at the tip, it is possible to use a single tool from the pilot hole to threading. Specifically, a bolt tap 6 is formed by attaching a drill tap to the spindle of the machining center.

  As described above, the bolt hole 6 is processed in the fixed blade plate 4 by utilizing the helical feed (arc) function of a machining center or the like. The position, size, number, etc. of these bolt holes 6 are not particularly limited.

  Next, an example of the configuration of the crusher 100 in which the fixed blade plate 4 and the movable blade plate 5 are installed will be described.

  38, 39, etc., the crusher 100 includes a pair of side frames 109, 109 arranged side by side, a fulcrum shaft 117 installed between the side frames 109, 109, and the crusher 100. The fixed blade plate 4 that is inclined or perpendicular to the fixed blade plate, and the fulcrum with the back and forth movement of the piston rod 107 of the cylinder 106 that is opposed to the fixed blade plate 4 and fixed to the cylinder fixing portion 108 of the crusher 100 The main component is a movable blade plate 5 that moves back and forth with a shaft 117 as a fulcrum.

  A V-shaped crushing space V is formed between the fixed blade plate 4 and the movable blade plate 5 arranged in the crusher 100, and an object to be crushed is introduced into the crushing space V, and the moving blade plate 5. Is moved forward with respect to the fixed blade plate 4, the object to be crushed is crushed, and the object to be crushed is discharged downward. That is, the crusher 100 is opened up and down, and has an upper open part 100a for feeding the material to be crushed and a lower open part 100b from which the crushed waste material is discharged.

  As described above, the fixed blade plate 4 is installed to be inclined or perpendicular to the crusher 100. As an example of installing the fixed blade plate 4 at an inclination, as shown in FIGS. 19 to 21, the fixed blade plate 4 is inclined and crushed through a holder 115 that supports the fixed blade plate 4 at an inclination. It can be installed in the machine 100. Further, as an example of installing the fixed blade plate 4 vertically, the fixed blade plate 4 is vertically installed in the crusher 100 via a holder 115 that fixes and supports the fixed blade plate 4 vertically (not shown). . In addition, it can be installed in a tilted or vertical position without using the holder 115. 24 and 25, the movable blade plate 5 can also be arranged in the crusher 100 with the holder 115 interposed, but the crusher can be arranged without the holder 115 as shown in FIGS. 38 and 39. It is also possible to install in 100.

  If the holder 115 for attaching the blade (blade plate) is not used, the cost can be reduced as a product, and the weight reduction is facilitated, so that the total weight of the crusher 100 can be suppressed. Become. Further, since the holder 115 is not used, the weight is reduced accordingly, so that the movable blade plate 5 can be moved back and forth with a small force.

  In FIG. 38, the fixed block 118 is installed in the crusher 100, and the fixed blade plate 4 is placed on the fixed block 118. The fixed block 118 may have any configuration and shape as long as the fixed blade plate 4 can be placed thereon. As an example, a main body part 118a having a substantially rectangular shape in cross-sectional view and an extension part 118b partially extending from the lower side of the main body part 118a are provided, and the extension part 118b has an inclined surface such as a slide. Conceivable. In addition, the length of the extension part 118b is not ask | required.

  An example of a method of installing the fixed block 118 and the fixed blade plate 4 on the crusher 100 will be described as follows. First, below the place where the fixed blade plate 4 is installed, the fixing block 118 is sandwiched between the side frames 109 and 109 and fixed to the side frames 109 and 109 with bolts or the like. Then, the fixed blade plate 4 is placed on the plane of the fixed block 118, the fixed blade plate 4 is sandwiched between the side frames 109 and 109, and fixed to the side frames 109 and 109 with bolts or the like. In this way, the fixed block is fixed to both side frames 109 and 109, and the fixed blade plate 4 placed on the fixed block 118 is also fixed to both side frames 109 and 109, thereby The plate 4 and the fixed block 118 are connected to each other in the vertical direction, and are fixed to the crusher 100.

  When the object to be crushed is finely crushed by each blade, the crushed object to be crushed is discharged by sliding on the slide along the extending portion 118b, but when the object to be crushed is a long object, A long object to be crushed is caught on an inclined surface such as a slide, so that the object to be crushed can be prevented from being discharged, and the object to be crushed on the inclined surface can be crushed by each blade. In other words, the extending portion 118b can also serve as a damper that prevents the discharge of the object to be crushed due to the inclined surface, as well as the discharge of the object to be crushed as a long object. As a material of the holder 115 and the fixing block 118, for example, special alloy steel or the like is adopted. Alternatively, the holder 115 and the fixed blade plate 4 may be integrated.

  The holder 115 for fixing and supporting the movable blade plate 5 shown in FIGS. 24 and 25 is pivotally supported by a fulcrum shaft 117 installed between the side frames 109 and 109. Specifically, it is pivotally supported on the fulcrum shaft 117 by a semicircular shaft support portion formed on the lower side of the holder. Then, the fulcrum shaft 117 is covered with a fulcrum shaft cap and fixed to the holder 115 with a fixing tool such as a bolt.

  The fulcrum shaft 117 is supported mainly using a bearing, a frame hole that is largely opened in both side frames 109 and 109, and a support block 116 that fits into the frame hole. Therefore, the position of the fulcrum shaft 117 can be changed by adjusting the number of the left and right support blocks 116 in the frame hole by using the insertion / extraction of the support block 116 fitted into the frame hole. That is, the crushing space V formed between the fixed blade plate 4 and the movable blade plate 5 when the movable blade plate 5 reaches the forward limit position can be adjusted.

  Further, if the position of the fulcrum shaft 117 is moved closer to the fixed blade plate 4 by adjusting the number of the support blocks 116, even if the movable blade plate 5 moves forward to the forward limit position toward the fixed blade plate 4, The angled blade portions 40 can be arranged without being fitted into the surrounding regions 7 of the fixed blade plate 4 and the movable blade plate 5. That is, depending on the adjustment of the position of the fulcrum shaft 117, when the movable blade plate 5 moves forward to the forward limit position, the angled blade portion 40 (the tip surface of the top cross band 41) of the fixed blade plate 4 and the movable blade plate 5 A space can also be formed between the surrounding region 7 and the angled blade part 40 (the tip surface of the top cross band 41) of the movable blade plate 5 and the surrounding region 7 of the fixed blade plate 4.

  When the fixed blade plate 4 is inclined and disposed in the crusher 100 and the movable blade plate 5 is also in the retreat limit position, the V-shaped crush formed between the fixed blade plate 4 and the movable blade plate 5. Since the space V can be widely taken, a relatively large object to be crushed can be input.

  Further, when the fixed blade plate 4 is arranged vertically in the crusher, the V-shaped crushing space V formed between the fixed blade plate 4 and the movable blade plate 5 is inclined by the fixed blade plate 4. However, when the movable blade plate 5 reaches the forward limit position, the movable blade plate 5 and the fixed blade plate 4 face each other substantially horizontally, and the fixed blade plate 4 and the movable blade plate 5 Therefore, the object to be crushed can be crushed more finely.

  As an installation method of the cylinder 106, for example, a method of attaching the trunnion-structure cylinder 106 to the cylinder fixing portion 108 of the crusher 100 and rotatably supporting the cylinder 106 by the trunnion is conceivable. Specifically, a trunnion bearing is attached to the cylinder fixing portion 108 of the crusher 100, and a trunnion structure cylinder 106 is pivotally attached to the trunnion bearing via a trunnion shaft.

  The cylinder 106 may be a fluid cylinder that uses hydraulic pressure or pneumatic pressure as a working fluid. For example, in the case of a hydraulic cylinder device, a linear feed drive mechanism that crushes the object to be crushed between the fixed blade plate 4 and the movable blade plate 5 by moving the piston rod 107 back and forth. Therefore, the movable blade plate 5 is gradually displaced by the linear feed driving device of the hydraulic cylinder, and a strong hydraulic pressure is applied to the object to be crushed to crush the object to be crushed.

  An opening is provided at the tip of the piston rod 107, and the clevis is rotatably coupled by a clevis pin. Then, the clevis and the moving blade plate 5 or the holder are fixed by attaching the mounting surface of the clevis to the back surface of the moving blade plate 5 or the back surface of the holder and fixing with a fixture such as a bolt. When the piston rod 107 expands and contracts, the movable blade plate 5 moves forward and backward with the fulcrum shaft 117 as a fulcrum. This forward / backward movement uses the lever principle with the fulcrum shaft 117 as a pivot point, can suppress the output of the cylinder 106, and can move the movable blade plate 5 with relatively small power.

  It is also possible to detachably install one or more liners inside the both side frames 109, 109, specifically, in the movable region of the movable blade plate 5 with a stopper such as a bolt. For this liner, for example, a high hardness material having wear resistance such as cemented carbide is adopted. By providing this liner on both side frames 109, 109, the side frames 109, 109 are crushed. Since it is possible to avoid an impact caused by an object, it is possible to improve the durability and extend the life of both side frames 109 and 109. Further, friction between the side frames 109, 109 and the blade plate can be avoided. The hardness of the liner is, for example, about HRC50 to HRC60. Moreover, the structure which processes the head of stoppers, such as a volt | bolt, with a grinding | polishing means substantially flush is desirable.
