 The cutter body of this type of plate shearing machine is held in the holder between the holder connected to the casing side of the hydraulic pump, the fixed blade fixed to the holder, and the fixed blade and the output shaft of the hydraulic pump. Equipped with a movable blade. The movable blade is a plate having a predetermined thickness, both sides of which are movably held by the holder, and moves in a direction orthogonal to the plate to be sheared. The plate-shaped body is, for example, a DIN rail made of aluminum with a hat-shaped cross section. The base end of the movable blade is engaged with the output shaft, and the tip is formed with a blade corresponding to the cross-sectional shape of the plate-shaped body. The fixed blade has a cutting hole into which the tip of the movable blade fits. When the hydraulic pump is operated and the movable blade is moved to the fixed blade side by the output shaft, the plate-like body is sheared by the cooperation of the movable blade and the fixed blade. When the return lever of the hydraulic pump is operated, the output shaft returns to its original position and the movable blade returns to the standby position.

[0003]

[Problems to be solved by the device]

 In a conventional plate-shaped body shearing machine, the movable blade cuts the plate-shaped body into a punch shape, so that scrap having a size corresponding to the thickness of the movable blade comes out and is wasted. Also, burrs were easily generated on the cut surface. An object of the present invention is to prevent scrap from being generated when a plate-shaped shearing machine for portable use is cut, and to prevent burrs from being generated on the cut surface.

[0004]

[Means for Solving the Problems]

 The present invention is a portable plate-shaped body shearing machine for shearing a plate-shaped body 3 by a cutter body 2 according to the output of a hydraulic pump 1, the cutter body 2 including a holder 11 connected to the hydraulic pump 1. , A fixed blade 15 having one side exposed and fixed to the holder 11, and a movable blade having one side exposed and the other side adjacent to the other side of the fixed blade 15 and moving in the same direction as the output shaft 7 of the hydraulic pump 1. And a blade 16. The fixed blade 15 and the movable blade 16 are provided with plate-shaped body insertion holes 29 and 31 corresponding to the cross-sectional shape of the plate-shaped body 3 penetrating both side surfaces thereof. Then, the output shaft 7 of the hydraulic pump 1 is operated to bring the movable blade 16 out of the standby position A in which the plate-shaped member insertion hole 31 of the movable blade 16 matches the plate-shaped member insertion hole 29 of the fixed blade 15. It is arranged so as to be moved to the shearing position B in the axial direction.

[0005]

[Action]

 When the movable blade 16 is set to the standby position A and the plate-shaped body 3 is inserted into the plate-shaped body insertion holes 29 and 31 of the fixed blade 15 and the movable blade 16, the plate-shaped body 3 penetrates the fixed blade 15 and the movable blade 16. Form. In this state, when the hydraulic pump 1 is operated and the movable blade 16 is moved to the shearing position B by the output shaft 7 of the hydraulic pump 1, the movable blade 16 is adjacent to the fixed blade 15 and the plate-shaped body of the movable blade 16 is inserted. Since the hole 31 is axially displaced from the plate-shaped body insertion port 29 of the fixed blade 15, the plate-shaped body 3 is cut on the surface side where the fixed blade 15 and the movable blade 16 are in contact with each other. Since one end of the plate-shaped body insertion hole 31 of the movable blade 16 is opened to one side surface exposed to the outside, the plate-shaped body 3 is not cut on this one side surface side.

[0006]

[Effect of device]

 As described above, according to the present invention, the fixed blade 15 and the movable blade 16 adjacent to the fixed blade 15 are provided with the plate-shaped body insertion holes 29 and 31 corresponding to the cross-sectional shape of the plate-shaped body 3 penetrating on both sides. Since the plate-shaped body 3 is inserted into the plate and the movable blade 16 is moved in a direction intersecting with the plate-shaped body 3, the plate-shaped body 3 can be cut on the surface side where the fixed blade 15 and the movable blade 16 are in contact with each other. As a result, scrap of the plate-like body 3 does not occur, and burrs are less likely to occur on the cut surface.

[0007]

EXAMPLE As shown in FIG. 2, the plate-shaped shearing machine of the present invention comprises a manual hydraulic pump 1 and a cutter body 2 which is detachably connected to the manual hydraulic pump 1 and has a cross section called a DIN rail. It is used when cutting the plate-shaped body 3 made of aluminum having a tongue shape. The hydraulic pump 1 has a general structure used for a terminal crimping machine or the like, has hydraulic oil in a fixed handle 4, and has a hydraulic pressure generation mechanism and a piston (not shown) built in a casing 5. ing. When the operating handle 6 pivotally attached to the casing 5 is operated, the operating oil in the fixed handle 4 is introduced into the hydraulic chamber provided on the top surface side of the piston, and the hydraulic pressure is applied to the piston. The piston pushes out the output shaft 7 at the tip according to the applied hydraulic pressure. When the return lever 9 provided on the side surface of the casing 5 is operated, the pressure on the piston is released, and the piston and the output shaft 7 are returned to their original positions by the spring in the casing.

As shown in FIGS. 1 and 3 to 5, the cutter body 2 is provided with a holder body 12 and left and right side plates 13 and 14, a fixed blade 15, a movable blade 16, and a pressing plate 17. ing. As shown in FIGS. 3 and 4, the holder body 12 has holding holes 19 penetrating both sides thereof, and a connecting arm 20 projecting to the hydraulic pump 1 side has a connecting arm 21 extending from the casing 5 and a plurality of connecting arms 21. They are connected via bolts 22 and the like. A pedestal 23 is fixed to the lower surface of the holder body 12 to ensure stability during work (see FIG. 2). The side plates 13 and 14 have windows 24 and 25 formed in the center thereof and are fastened to the side surfaces of the holder body 12 by a plurality of bolts 26, respectively.

The fixed blade 15 is fitted in the holding hole 19 as shown in FIGS. 3 and 4, and the central portion of one side surface is exposed to the outside through the window 24, and the exposed portion has a plate-like shape. The body insertion hole 29 is exposed. The plate-shaped body insertion hole 29 penetrates one side surface and the other side surface of the fixed blade 15, and is formed so as to correspond to the cross-sectional shape of the plate-shaped body 3. Specifically, as shown in FIG. 5, the wide portion of the U-shape is set to 3 mm and both sides are set to 2 mm, and the output shaft 7 is tilted at a fixed angle θ (45 °) so that the output shaft 7 moves in the direction of movement. In contrast, they are orthogonal.

As shown in FIG. 5, the movable blade 16 is exposed at the center portion of one side surface through the long hole 30 of the pressing plate 17 and the window 25 of the side plate 14, and the other side surface as shown in FIGS. 3 and 4. Is joined to the other side surface of the fixed blade 15 and disposed in the center of the holder body 12. The plate-shaped body insertion hole 31 of the movable blade 16 penetrates through the both sides in the same manner as the plate-shaped body insertion hole 29 of the fixed blade 15, and on the side of the holding plate 17 is always outside through the slot 30 and the window 25. It is exposed to. The input shaft 32 is provided on the surface of the movable blade 16 facing the output shaft 7, and the compression coil spring 33 is arranged on the surface opposite to the input shaft 32 to urge the movable blade 16 to move toward the output shaft 7. . One end of the compression coil spring 33 is held by the bolt 34 attached to the holder body 12. Thus, the movable blade 16 moves between the standby position A in which the plate-shaped member insertion hole 31 communicates with the plate-shaped member insertion hole 29 of the fixed blade 15 in the left-right direction and the shearing position B in which the plate-shaped member insertion hole 31 does not communicate in the left-right direction. (See FIG. 6). The pressing plate 17 is fitted in the holding hole 19, and a long hole 30 obliquely provided in the central portion penetrates left and right. In FIG. 2, reference numeral 35 is a gauge plate that displays shear force.

Next, a cutting mode of the plate-shaped body 3 by the plate-shaped body shearing machine will be described. The movable blade 15 is set to the standby position A, and the plate body 3 is inserted from the window 24 side of the side plate 13 into the plate body insertion holes 29 and 31 of the fixed blade 15 and the movable blade 16. Although depending on the cutting size of the plate-like body 3, the tip of the plate-like body 3 is projected from the other side plate 14 side through the insertion holes 29 and 31, the elongated hole 30 and the window 25. When the operating handle 6 is operated after positioning the plate-like body 3, the output shaft 7 moves the movable blade 16 from the standby position A to the shearing position B via the input shaft 32 as shown in FIG. At that time, since the other side surface of the movable blade 16 is in close contact with the other side surface of the fixed blade 15, the plate-shaped body insertion hole 31 of the movable blade 16 is axially displaced from the plate-shaped body insertion opening 29 of the fixed blade 15. The body 3 is cut on the surface side where the fixed blade 15 and the movable blade 16 are in close contact with each other. The pressing plate 17 is joined to one side surface of the movable blade 16, but since the tip end side of the plate-shaped body 3 is allowed to move in the axial direction in the elongated hole 30, the plate-shaped body 3 is connected to the pressing plate 17 side. There is no cutting or bending.

As described above, according to the plate-shaped body shearing machine, since the plate-shaped body 3 can be cut on the surface side where the fixed blade 15 and the movable blade 16 are in close contact with each other, scrap is not generated and the plate-shaped body is not scraped. 3 can be effectively used over both ends. In addition, burrs are less likely to occur on the cut surface of the plate-like body 3, and deburring work after cutting is unnecessary.

(Another embodiment example) If a plurality of cutter bodies are prepared and the shape of the plate-like body insertion holes of the fixed blade and the movable blade is made different for each cutter body, the cross section can be changed only by replacing the cutter body. It can also be applied to other plate-shaped bodies having different shapes.
