Definitions
- the present invention is applicable to manual machines for cutting ceramic pieces, such as tiles, tiles and the like.
- Manual machines for cutting ceramic pieces comprising a base for supporting the piece to be cut; and some longitudinal guides on which is mounted a carriage that can be moved longitudinally and on which, in turn, is mounted a cutting device with the possibility of turning about a horizontal axis, perpendicular to said guides.
- Said device comprises a support provided with a vertical hole for assembling a cutting tool and a horizontal threaded hole in which a handle for fixing the cutting tool and for actuation of the same both in the rotation and rotation movement is mounted. longitudinal displacement.
- the cutting tool comprises a bar provided with a first end that is inserted into the vertical hole of the support and a second end on which a cutting wheel is mounted to mark a break line on the ceramic pieces,
- the bar of the cutting tools generally circular in section, has a smooth front face, and at least one longitudinal, lateral or rear slot, which receives inside it a respective anti-rotation appendage defined in the vertical hole of the support when it is mounted. the cutting tool on the support.
- Another drawback is that during assembly, the cutting tool must be placed at a suitable height so that when the handle is lowered, which acts as a lever, the cutting wheel contacts the ceramic piece to be cut.
- the user must hold the cutting tool with one hand and rotate the handle with the other hand so that it is threaded into the horizontal hole of the support and presses with its front end the flat front face of the cutting tool bar. court.
- Another drawback is that once the cutting tool is tightened with the handle, a slight involuntary rotation of the handle in the direction of loosening can occur during operation of the cutting machine, with the consequent reduction in the clamping force of the cutting tool. by the handle and the involuntary change of the height position of said cutting tool. This change in position of the cutting tool occurs when the cutting wheel is pressed against the ceramic piece to mark the cutting line on said ceramic piece.
- the technical problem that arises is the development of a cutting device for manual ceramic cutting machines, which facilitates the assembly, change of position and fixing of the cutting tool with respect to the support without the possibility of slipping.
- the cutting device for ceramic cutting machines object of this invention presents some technical characteristics that provide a series of advantages with respect to the state of the art; specifically: It allows the height position of the cutting tool to be varied in a controlled way, placing it in a series of consecutive and predetermined positions.

- this cutting device comprises a rod housed in the horizontal hole of the support with the possibility of movement between: an anterior locking position of the cutting tool, in which the anterior end of said stem is housed in said vertical hole, and a rear release position of the cutting tool.
- the bar of the cutting tool includes on its front face at least one row of recesses spaced apart in the vertical direction, and the stem includes at its front end at least one protrusion which, in the position before the cutting tool is locked by part of the stem is housed in one of the recesses on the front face of the bar of the cutting tool.
- Said shank comprises a rear end facing a front end of the handle.
- Said handle is mounted on the support with the possibility of movement between: a rear position in which said handle is distanced from the rear end of the rod and allows its withdrawal; and an anterior position in which said handle acts against the posterior end of the stem, preventing its return and fixing it in the anterior position of blockage of the cutting tool.
- the bar of the cutting tool includes at its first end a ramp, inclined towards its front face, the function of which is to facilitate its introduction into the vertical hole of the support, acting against the front end of the rod and causing it to recede.
- the protrusion defined at the front end of the rod is housed in one of the recesses in the cutting tool bar, preventing it from slipping and changing the position in height of said cutting tool when pressing the wheel. cut against the ceramic piece to be cut, even if the clamping force of the shank against the bar of the cutting tool is small.
- the rod comprises an intermediate thickening arranged between a front stop of the support and an annular stop, with adjustable position, mounted by screwing on the rear threaded section of the support.
- the device comprises a spring that pushes the rod inside the horizontal hole towards the anterior locking position of the cutting tool, said rod exerting continuous pressure against the front face of said bar.
- This thrust spring is mounted between the intermediate thickening of the stem and annular stop screwed onto the rear threaded section of the support.
- the device comprises inside the horizontal hole of the support a spring that pushes the stem towards the rear release position of the cutting tool; in this case, it is necessary to move the rod, by means of the handle, towards the previous position in order to hold and block the cutting tool with respect to the support.
- the spring for pushing the stem towards the rear position is mounted between the front stop of the support and the intermediate thickening of the stem.
- the annular stop mounted on the rear threaded section of the horizontal hole of the support includes an internal hole for longitudinal guidance of the rear end of the rod.
- Figure 1 shows a manual ceramic cutting machine, carrying the cutting device object of the invention.
- Figure 2 shows a perspective view of the cutting device of the invention in which the axis of rotation of the support with respect to the carriage for longitudinal displacement on the guides of the cutting machine has been removed.
- Figure 3 shows an exploded elevation view of the cutting device of the invention provided with a spring that pushes the stem in the frontal direction and sectioned by a vertical plane, with the exception of the cutting tool.
- Figure 4 shows a perspective view of an embodiment of the cutting tool.
- Figure 5 shows a perspective view of an embodiment example of the rod.
- Figure 6 shows a view in elevation of the cutting device of figure 3 in the assembled position, vertically sectioned, and with the handle and stem in the anterior position for locking the cutting tool.
- Figure 7 corresponds to a plan view of the cutting device, with the support sectioned by a horizontal plane, and with the rod and the handle in the same previous position of figure 6.
- Figure 8 shows a view similar to figure 6, with the handle in a rear position, in which it allows an alternative movement of the rod forward and backward, and the change of position in height of the cutting tool.
- Figure 9 shows an elevation view of a variant of the cutting device, which includes a spring in the horizontal hole that moves the rod towards a rear position for releasing the cutting tool, and in which the rod has been represented. in said rear position.
- Figure 10 shows a view similar to figure 9, with the stem and the handle in a position before the cutting tool is locked.
- Figure 1 shows the cutting device of the invention mounted by means of a horizontal axis (E) of rotation on a carriage (C) that can be moved along longitudinal guides (G) of a manual ceramic cutting machine. .
- Figure 2 shows the cutting device of the invention isolated and without the horizontal axis (E) of rotation to simplify the drawing and in which the support (1) for mounting the cutting tool (2) can be seen. and the handle (3) for fixing and actuating the cutting tool.
- Figure 3 shows an embodiment of the exploded cutting device, showing the different elements that make it up, specifically: the support (1), the cutting tool (2), the handle (3), the rod (4), a spring (5a) for pushing the rod towards a previous position, and annular stop (6).
- the cutting tool (2) comprises a bar (21) provided with: a first end (22) with a ramp (23) inclined towards a front face
- the recesses (27) have a length that coincides with the width of the front face.
- the bar (21) additionally has longitudinal channels (28) on the lateral and rear faces, shown in figure 7, for receiving appendages (15) defined in the vertical hole of the support (1) and mounting them in a position angle determined in said support (1).
