Definitions
- the present invention relates to a disassembly cutter used by being attached to an end of an arm of a hydraulic shovel or the like.
- dismantling cutting machine used for dismantling a dismantled product for example, one described in Japanese Patent No. 25556664 is conventionally known.
- This dismantling and cutting machine is different from the term used in the official gazette, except that an arm pin is provided between side plates of a bracket that is detachably attached to an arm tip of a construction machine, and is supported so as to be able to open and close around the arm pin.
- An open / close cylinder is connected to each of the pair of arms, and each open / close cylinder is actuated to swing each arm in the closing direction, so that a cutting blade formed on a side edge of a cutting mating surface overlapping each other is provided.
- An object to be cut such as a reinforcing bar, is cut off by scissors.
- FIG. 10 (I) is a developed view showing the relationship between the arm of the dismantling and cutting machine and the opening / closing cylinder described in the above-mentioned publication, where 41 is an arm pin, 42 a and 42 b are centered on the arm pin 41.
- the arms 43a and 43b are openably and closably supported, and open and close cylinders of the arms 42a and 42b.
- reference numeral 44 denotes a cutting mating surface
- 45 denotes a cutting blade.
- FIG. 10 (I) is a development view, two arm pins 41 are used, but the arm pins 41 are common.
- the centers of the opening and closing cylinders 43a and 43b are positioned on a plane including the cutting mating surface 44 formed on each of the arms 42a and 42b.
- the pressing force of the opening / closing cylinders 43a, 43b pressing the arms 42a, 42b in the closing direction acts on the plane X, including the cutting mating surface 44, and FIG.
- (II) it is not possible to prevent the distal ends of the arms 42a and 42b from escaping outward and deforming outwardly during cutting, and the object to be cut if used continuously Cannot be cut smoothly.
- a pin hole 46 formed in the arm 42 a, 42 b is provided. Since there is a small fitting gap between the arm pin 41 inserted into the pin hole 46 and the cutting blade 45 when the workpiece W is cut obliquely when cutting the workpiece W, The tip of the arm 42a escapes outward, and the arms 42a and 42b are tilted outward as shown in Fig. 10 (II) within the range of the above-mentioned fitting gap. It cannot be suppressed by the pressing force of the opening / closing cylinders 43a and 43b. For this reason, the cutting blades 45 of the pair of arms 42 a and 42 b start cutting in a state where a gap is formed between the cut mating surfaces 44, and the cutting force is reduced to cut. The object W cannot be cut smoothly.
- the arms 42a and 42b are tilted outward, so that the inner surfaces of the rear ends of the arms 42a and 42b on the pivot center side are at points P and P.
- the arms 42a and 42b are tilted outward, so that the inner surfaces of the rear ends of the arms 42a and 42b on the pivot center side are at points P and P.
- strong contact arm pin 4 1 plates 4 7 and the arm 4 2 a, 4 2 b of brackets for supporting strongly contact resistance increases by a point P 2
- a pair of arms 4 2 a, 4 2 b cannot be swung smoothly in the closing direction, and a large bending load acts on the center of the arm pin 41 in the longitudinal direction, causing the arm pin 41 to bend and the arm pin 41 to be damaged. Occurs.
- both cutting mating surfaces 44 of both arms 42a and 42b are located on the same axis as the thrust direction when the cylinder is extended, both cutting mating surfaces 44 are cut out to form cutting blades 45. There is a need to. For this reason, the thickness of the cutting blade portion is reduced, and in order to reinforce the cutting blade portion, it is necessary to devise measures such as providing a reinforcing material in this portion.
- the cylinder body of the opening / closing cylinders 43a and 43b is connected to the movable bracket, and the piston rod is connected to the arm.
- the piston rod comes into contact with obstacles during the dismantling work and is likely to be damaged.
- a first object of the present invention is to provide a cutting joint surface in which when the arm is closed by the operation of the opening / closing cylinder, the inclination of the arm and the outward deformation of the distal end portion can be suppressed by the pressing force of the opening / closing cylinder.
- An object of the present invention is to provide a dismantling cutter capable of preventing a gap from being formed therebetween and smoothly cutting an object to be cut.
- a second object of the present invention is to provide a compact and compact dismantling and cutting machine which can prevent the damage of the bistro rod of the opening and closing cylinder for opening and closing the arm and can perform the dismantling work efficiently.

- the workpiece W can be cut by the extension of the opening / closing cylinders 14a and 14b.
- a large tensile force (a force that prevents the arms 9a and 9b from escaping outward) is applied to the connection between the arms 9a and 9b and the cylinders 14a and 14b.
- the bending stiffness of the arms 9a and 9b is increased, and the formation of the cutting blades 12 of the arms 9a and 9b can be prevented from escaping outward or deforming.
- the object to be cut W can be cut more effectively.
- At least one of the opening / closing cylinders for opening / closing the arm is offset to the outside of the cut mating surface formed on the arm, so that the opening / closing cylinder is opened and closed. It is possible to suppress the arm from tilting outward when the object is cut by the pressing force. Therefore, when the object is cut, a gap is rarely formed between the mating surfaces of the pair of arms, and the object can be cut smoothly, and the outer side of the joint surface of the arms can be cut. This eliminates the need for mounting components such as pad guide blades that prevent movement to the machine, so that an inexpensive cutting machine with a small number of components and low cost can be obtained.
- the pressing force of the opening / closing cylinder acts on a position offset from the longitudinal center of the arm pin toward the end, so that the bending of the arm pin can be suppressed.
- a relatively small diameter arm pin can be employed.
- the bending rigidity of the arm can be increased, and the escape or deformation of the arm in the outward direction when cutting the object to be cut can be suppressed.
- the piston rod of the opening / closing cylinder can be always covered by the movable bracket, it is possible to prevent the piston rod from being hit by an obstacle and being damaged during dismantling work.
- the first oil passage communicating with the front room of the biston is connected to the biston rod of the opening / closing bracket.
- the provision of the second oil passage communicating with the post-ston chamber enables the movable bracket to cover the hydraulic hose that connects each oil passage with the first and second oil ports of the rotary joint.
- the hydraulic hose is caught on the dismantled object during the dismantling work and hinders the work, and the dismantling work can be performed efficiently.
- the first and second oil inlets and outlets are provided on both sides of the rotary cylinder of the rotary joint, so that the end of the hydraulic hose connected to each oil inlet and outlet is located on the side of the joint. As a result, the width between the pair of opposed side plates of the movable bracket can be reduced.
