Description

Slab cutting device

The present invention relates to a slate cutting apparatus having a simple structure, excellent mobility, no risk of failure, and an operator can easily cut a slate in a straight or oblique direction, and furthermore, it is easy to operate and has very excellent ease of use.

In general, plate-shaped stones used for flooring, exterior finishes, and other various purposes of buildings are supplied in a certain thickness and size in advance, so at work sites where such stones are used directly, the stone is randomly selected in a predetermined size as needed. There are cases in which it is necessary to cut and use.

However, until now, since the operator has manually cut the stone using a hand grinder type cutter, it is difficult to accurately cut the stone along with the risk of work safety such as physical damage due to the cutting of the stone. Again, there was a problem that it had to be slow.

In addition, since it is a method of cutting while an operator directly grasps the handle of the cutter and moves the saw blade relative to the stone, considerable skill is required for the cutting operation.

On the other hand, breaking away from the conventional hand grinder method, cutting machines for more stable cutting have been proposed as KR10-2005-0029062A (automatic stone cutting machine, hereinafter referred to as'patent document 0001').

Patent Document 0001 relates to a stone cutter for easily cutting and using the stone material supplied by cutting in a plate shape to the required size at the work site, and has the advantage of greatly improving the quick and accurate cutting of stone and work safety through stable automatic transfer of the circular cutter. , There is a disadvantage that the operation is inconvenient.

The auxiliary guide body 105 moves left and right from the other side of the guide body 101 in one direction, so that the lower part of the slate cutting part 30 is moved to the lower part of the slate cutting part 30 with respect to the upper one side of the slate cutting part 30. It can be moved up and down in the vertical direction.

The other side of the leadscrew 106 may pass through one side of the guide body 101 and be introduced into the guide body 101 at a predetermined length.

The other side of the lead screw 106 may be connected to the rear side of the auxiliary guide body 105 while being screwed with the fixed body 102 and passing through the rear side of the auxiliary guide body 105.

In order to prevent the auxiliary guide body 105 from being separated from the other side of the leadscrew 106, as shown in FIG. 16, on the other side of the lead screw 106 around the rear side of the auxiliary guide body 105 The departure prevention protrusion 106a may be formed in a radial shape.

The separation prevention protrusions 106a may be disposed at regular intervals from one side of the lead screw 106 to the other side, and the rear side of the auxiliary guide body 105 may be located between the separation prevention protrusions 106a. have.

17 is a partial front view schematically showing a state in which the slate cutting portion is raised.

Although not shown in the drawing, a handle for rotating the leadscrew 106 may be provided on one side of the leadscrew 106, and the operator can rotate the leadscrew 106 forward and backward using a handle. .

When the leadscrew 106 is rotated in the forward direction, the leadscrew 106 is pulled out of the guide body 101 as shown in FIG. 17, and the auxiliary guide body 105 is moved to the guide body 101. In this case, the upper part of the guide plate 103 is moved in one direction of the slate cutting part 30, and the slate cutting part 30 is based on the upper one side of the slate cutting part 30. The lower part of the can be raised.

When the leadscrew 106 is rotated in the reverse direction, the leadscrew 106 is drawn into the guide body 101 to move the auxiliary guide body 105 toward the other side of the guide body 101. In this case, as the upper part of the guide plate 103 moves in the direction of the other side of the slate cutting part 30, the lower part of the slate cutting part 30 may be lowered based on the upper one side of the slate cutting part 30. have.

As shown in FIGS. 15 and 16, the connecting member 107 may be largely configured to include a connecting shaft 107a and a nut 107b.

The connection shaft 107a is sequentially horizontally passed through the upper portion of the guide plate 103 and the guide slit 101a of the guide body 101 to be screwed or welded to the front side of the auxiliary guide body 105, etc. It is connected in various ways and may be formed of various types, such as a bolt connecting the upper portion of the guide plate 103 to the front side of the auxiliary guide body 105.

The nut 107b is screwed to a bolt that can form the connection shaft 107a to closely fix the guide plate 103 to the front side of the guide body 101 to lift the lower part of the slab cutting part 30 It can be fixed in position.

The present invention configured as described above has a simple structure that is movable in the longitudinal direction disposed on the upper side of the base part 20, has excellent mobility, and uses the slab cutting part 30, which is free from troubles, so that the operator can use the base part. Not only can the slate 3 seated on the upper part of the slate 3 be easily cut in a straight or oblique direction, but also the slate cutting part 30 can be easily operated by a simple operation of the intermittent lever 50 of the moving part 40. It has the advantage of being very easy to use because it can control the movement.
