Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The present invention relates to a brick chamfering device used for chamfering the ridgeline portion of a molded and cut brick base.

Conventional technology In order to improve the commercial value of ceramic products such as bricks, there are so-called chamfered products with chamfered edges, but when manufacturing such chamfered bricks, conventional manufacturing processes are required. In this method, chamfering is applied to the molded material after extrusion molding by means such as pressing a wedge-shaped engraving blade during cutting or pressing a roller against the ridgeline of the molded material after cutting. In any of these operations, an unreasonable external force is applied to the molded base material, which causes distortion in the molded base material, resulting in deformation during drying and firing, making it impossible to obtain high-quality chamfered bricks. .

Furthermore, with the method of pressing a wedge-shaped engraving blade during cutting, it is extremely difficult to cut the pier wire so that it perfectly aligns with the center of the V-shaped groove, and as a result, excessive protrusion occurs, making it difficult to This method requires an extra finishing step such as removing the tensioned portion by finishing separately, which makes the manufacturing process extremely complicated and the device complicated.

Problems to be Solved by the Invention The present invention aims to provide a brick chamfering device that has a simple structure, performs chamfering using a conventional cutting device, and does not apply excessive external force to the molded material.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention is a brick structure in which horizontal rods are fixed to a frame, mounting plates are provided perpendicularly to the horizontal rods, and chamfered blades with sharp tips are horizontally attached to the vertical rods. The present invention aims to solve the above-mentioned drawbacks by providing a chamfering device.

Function: In the present invention, the cut molded material on the pedestal is pushed through a chamfering tool using a pusher to chamfer the ridgeline.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a chamfering device following an extrusion molding device and a cutting device, and the chamfering device 1 fixes a pressing device 3 on a pedestal 2; A chamfering tool 4 is fitted and fixed in front of the pressing device 3.

To explain the configuration of the pressing device 3, the pusher cylinder 5 is fixed on the pedestal 2 in the direction of the chamfering tool 4, and guides 6, 6a are fixed on both sides of the pusher cylinder 5 on the pedestal 2. The guide shafts 7, 7 are inserted into the interior so as to be freely advanced and retracted.
A is arranged in the 4 directions of the chamfering tool, and the rod 8 of the pusher cylinder 5 and the guide shaft 7,
A pusher 9 is fixed at right angles to the tip of 7a.

Next, to explain the structure of the chamfering tool 4, two horizontal rods 11, 11a are mounted on vertical frames 10, 10a.
The horizontal rods 11, 11a are provided with vertical rods 12 at right angles in the center, and mounting plates 13, 13a are attached to the side edges of the frames 10, 10a at both ends.
Chamfering blades 14, 14a with sharp tips are horizontally attached to the vertical rod 12 and the mounting plates 13, 13a.

Next, to explain the function of the brick chamfering device according to the present invention, as shown in FIG. 1, the frame 1 of the chamfering tool 4 is
0 and 10a are inserted and fixed, the cut molded material W is placed on the pedestal 2 by a belt conveyor, etc., and the pusher 9 is advanced by the action of the pusher cylinder 5, and the molded material W is chamfered. When pressed in four directions and further passing through the chamfering tool 4, the ridgeline portion of the molded material W is chamfered by the chamfering blade 1.
4, 14a are chamfered.

[Effect of idea]

In short, the present invention fixes the horizontal rods 11, 11a to the frames 10, 10a, and
Since the chamfering blades 14, 14a with sharp tips are horizontally attached to the mounting plates 13, 13a and the vertical rod 12, which are provided perpendicularly to a, the bricks can be cut by simply inserting and fixing the chamfering tool 4 into a conventional piano wire cutting device. It can be used as a chamfering device and has a simple structure, and the chamfering shape can be made using the chamfering tool 4 or the chamfering blade 14,
Changes can be made easily by simply replacing 14a, and since the chamfered blades 14 and 14a have sharp edges, no excessive external force is applied to the molded material W, so it does not deform during drying or firing. Its practical effects, such as being able to manufacture good-quality chamfered bricks without causing chamfering, are tremendous.
