DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a general view of a device for shaping score lines on a hard inorganic plate material according to the present invention. In the figure, 1 is a machine frame, 2 is an upper impactor, and 3 is an upper impactor. An air cylinder 2 to which 2 is attached, 4 is a lower impactor, 5 is an air cylinder to which the lower impactor 4 is attached, 6 is an air supply source having an air tank, and 7 is a foot switch for operating the air supply source 6. Switch means such as P, and P indicates a hard inorganic plate material to be processed.

The impactors 2 and 4 will be described with reference to the upper side shown in FIG. 2. The impactors 2 and 4 are formed of abacus bead-shaped pieces which are formed as sharp pointed portions 20 (40) having a sharp circumference. The abacus ball-shaped impactor 2 is rotated by a spindle 21 on a cylinder rod 30 of the air cylinder 3 (however, the lower impactor 4 is a guide block protruding from the cylinder body of the air cylinder 4 as described later). It is installed freely. These impactors 2 and 4 are configured such that the pointed portions 20 (40) are simultaneously made to impinge on the plate surface from above and below through the hard inorganic plate material P to form a dividing line due to plastic deformation on the hard inorganic plate material P. Further, the lower impactor 2 is also provided as a support means of the hard inorganic plate material P which brings the plate surface into contact with the tip portion 20 to move and feed the hard inorganic plate material P along the shaping direction of the score line. ..

The air cylinder 3 is for oscillating the upper impactor 2 by repeating air supply and exhaust, and is provided by fixing the cylinder body 31 to the machine body frame 1. Further, the air cylinder 3 is equipped so that the impactor 2 is slightly vibrated by the cylinder rod 30 repeatedly projecting and retracting as air is supplied and exhausted, and the cylinder rod 30 extends to a predetermined position by air pressure. Along with this, air leakage from the cylinder body 31 causes the cylinder rod 30 to be pulled and displaced in the contraction direction by a coil spring (not shown) housed inside the cylinder body 31.

The air cylinder 5 is such that the cylinder body 50 moves up and down, and is provided by fixing a pinton body 51 formed in a block shape to the machine body frame 1 so as to guide the up and down movement. In this air cylinder 5, the impactor 4 is rotatably mounted on a guide block 52, which is provided on the upper end surface of the cylinder body 50, by a support shaft 41. The air cylinder 5 slowly lowers the cylinder 50 by the impact force applied from the upper impactor 2 and ascends when the impact force is released to move the lower impactor 4 up and down. It is configured as a mechanism that displaces to.

A common air supply source 6 is connected to the air cylinders 3 and 5 in order to simplify the mechanism. In order to cause the air cylinders 3 and 5 to perform the above-described predetermined operation using the common air source 6, the lower impactor 4
The air cylinder 5 equipped with the upper impactor 2 is connected to the air supply source 6 via the air pipes 53a and 53b having a diameter relatively smaller than that of the air pipe 32 of the air cylinder 3 equipped with the upper impactor 2. It is constructed so as to move slowly against the impact force acting from the impactor 2. Further, the air cylinder 5 is connected to an air supply source 6 via an air regulator 54, and is configured to perform air supply or discharge as the cylinder body 50 moves up and down.

The impactor 2 on the lower side is provided as a support means for moving and feeding the hard inorganic plate material P as described above, and is shown in FIGS. 3 and 4 in order to stably support the hard inorganic plate material P. Thus, the mounting table 8 for the hard inorganic plate material P may be mounted on the lower air cylinder 5.

The mounting table 8 is mounted on the cylinder main body 50 of the air cylinder 5 so that an operator holds it with the hard inorganic plate material P from left and right and moves it horizontally, and at the center of the plate surface. Is provided with a gap 80 having a predetermined width in a straight line in the feeding direction so that the impactor 4 bearing-mounted on the guide block 52 of the air cylinder 5 is located above the plate surface of the mounting table 8. Further, on the mounting table 8, restriction plates 81 and 82 are provided on the left and right sides with a gap 80 therebetween on the lower side of the plate surface, and the guide plates 52 of the air cylinder 5 are slidably slidably sandwiched between the restriction plates 81 and 82. By doing so, the mounting table 8 can be stably moved and fed along the interval 80.

In the device for shaping a score line for a hard inorganic plate material having such a construction, a score line can be inserted so as to cut a plate material to be constructed as a roof laying plate or the like in accordance with the construction site. The hard inorganic plate material P is placed on the mounting table 8 and held by a worker by hand to position it on the cylinder body 50 of the air cylinder 5, and the air cylinders 3, 5 are vibrated by the switch means 7 such as a foot switch. When actuated, the hard inorganic plate material P supported by the lower impactor 4 as the stroke of the lower air cylinder 5 is extended.
Is lifted upward, and the impactor 2 that moves downward by the stroke extension of the upper air cylinder 3 abuts against the hard inorganic plate material P, so that the hard inorganic plate material P is impacted by the impactors 2 and 4 and the relative position of the impactor 2 and the vertical direction. At the same time, the impact force is applied instantly. After the operation, each cylinder 3, 5 undergoes a predetermined movement to reduce the stroke, and intermittently operates to apply an impact force again.

With the application of this impact force, a certain amount of impact force acts on the hard inorganic plate material P from the upper and lower impactors 2 and 4 at the same time, thereby weakening the portion to which the impact force is applied to the hard inorganic plate material P. Plastic change. This plastic change can be shaped as a dividing line of the hard inorganic plate material P if an operator moves the hard inorganic plate material P together with the mounting table 8 along the cutting line.

In the process of shaping the score line, each impactor 2, 4
Is formed in the shape of an abacus ball and is rotatably supported, so that the worker can hold the mounting table 8 together with the hard inorganic plate P by hand even when the impactors 2 and 4 repeat sudden movements. It can be moved and sent to. Further, even if the impact force is applied from the upper and lower impactors 2 and 4 to the hard inorganic plate material at the same time, immediately after the impact force is applied, the air cylinder 5 sandwiches the hard inorganic plate material P with the stroke extension of the air cylinder 3. By being pressed, the cylinder body 50 together with the impactor 4 is displaced downward slightly, so that a cushioning action is provided so that the hard inorganic plate material P is not cracked in a complicated manner. After that, the air cylinder 2 discharges air to reduce the stroke of the cylinder rod 20 and the cylinder body 50 of the air cylinder 5 moves upward.
The dividing line can be efficiently formed on the hard inorganic plate material by repeating the sudden operation of 5.

The dividing line is shaped so that shallow groove lines are formed on the upper and lower plate surfaces of the hard inorganic plate P, and the hard inorganic plate P is applied to a ruler or the like with the groove lines as a guide to apply a load to one side of the plate. In addition, the hard inorganic plate material P is shaped as a dividing line that can be easily split into a predetermined shape.

As described above, according to the device for shaping a split line for a hard inorganic plate material of the present invention, an impact force is applied from the upper and lower impactors to the plate surface of the hard inorganic plate material in order to suppress the generation of dust and the like. By doing so, the dividing line is shaped, and the dividing line can be shaped efficiently and without causing a situation in which the hard inorganic plate material is complicatedly damaged.
