Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refractory vibration forming apparatus.

[0002]

[Prior Art]

 Mechanical molding methods, rammer molding methods, sludge casting methods, etc. are known as molding methods for refractory materials, but in the case of small lots and irregular shapes, rammer molding methods are mainly used.

A conventional manual air rammer molding machine transmits mechanical vibration to a molding mallet through a cylinder shaft by controlling compressed air to crush solidified refractory material and other powder and granules. While pressing the switch, the operator holds the main body of the rammer directly in his / her hand to perform the tamping work by the vertical movement.

In this case, since the rammer molding machine is large and heavy, it is not easy to handle, and the vibration of the rammer is directly transmitted to the human body, resulting in great fatigue of workers and an important problem in work accidents. (Wax disease). Furthermore, molding work using an air rammer requires skill, and it is difficult to secure human resources at present, as the number of technicians is decreasing.

[0005]

[Problems to be solved by the device]

 According to the conventional manual rammer molding, all the work such as molding is performed manually, which causes the following problems.

1) Special skills are required, but the number of skilled workers tends to be small, resulting in a shortage of manpower.

2) Since the air rammer is held by hand, its vibration may cause labor problems such as white wax.

3) It is impossible to verbally explain all the procedures when forming by an air rammer or when teaching to a new worker, and most of the work contents must be empirically learned by the worker himself / herself.

[0009]

[Means for Solving the Problems]

 The present inventors have developed a refractory molding apparatus that solves various deficiencies of the conventional method and that allows non-experts to mold deformed bricks of desired quality and prevent labor accidents such as white wax. The technical construction of the present invention comprises a table (4) for mounting the molding frame (1) under the frame (7) and an eccentric weight vibrator (10) over the frame (7). A refractory forming apparatus equipped with a pressurizing device (9) having a built-in device, provided with an insert plate device (6) which moves forward and backward facing the upper surface of the table (4) and is formed below the table (4). A frame elevating device (5) is provided, and the pressurizing device (9) is suspended up and down on the frame (7) via an elevating cylinder (8), and the molding frame (1) is a vertically open type. It is a hollow body, and upper and lower punches (3) and lower punches (11) are inserted into the forming frame. Characterized in that it is arranged to, Ru refractory vibration molding apparatus der.

A detailed example of the device of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 are partial sectional front views showing an example of the vibration forming apparatus of the present invention in the order of operation, and FIG. 6 is a side view of FIG.

In the figure, reference numeral 7 denotes a frame, a table 4 on which the molding frame 1 is placed is provided at a lower portion of the frame 7, and an eccentric weight vibrator 10 is contained at an upper portion of the frame 7. A pressure device 9 is provided, and the pressurizing device 9 is moved up and down by the operation of the lifting cylinder 8.

On the upper surface of the table 4, as shown in the drawing, an insert plate device 6 which moves forward and backward to face each other is provided. Below the table 4, an air cylinder 14, an arm member 15, a push-up rod 16 and The molding frame elevating device 5 including a roller 13 arranged at the upper end of the push-up bar is provided, and 12 is a slit for the push-up bar 16 to project.

Reference numeral 1 denotes a forming frame (a wooden frame may be used), which is an assembling type or an integrated type that can be disassembled and has an open upper and lower type. 2 is a kneaded material to be formed.

The molding operation of the device of the present invention will be described in the order of FIGS.

The dough 2 is loaded into the forming frame 1 into which the lower punch 11 is inserted, set by the upper punch 3, placed on the roller 13, and placed at a predetermined position on the table 4 (at a predetermined position on the table 4). A forming frame may be arranged and the dough 2 may be charged). There is a gap between the upper end surface of the roller 13 (that is, the bottom surface of the forming frame) and the upper surface of the table 4 so that the insert plate can be inserted (see FIG. 1).

The insert plate device is operated to insert the insert plate into the gap, and the forming frame elevating device 5 is lowered to place the forming frame 1 on the insert plate (see FIG. 2).

While rotating the eccentric weight vibrating machine 10 in opposite directions, the lifting cylinder 8 is operated to lower the pressurizing device (l ₀ → l ₁ ), pressurizing and preforming the vibrating upper punch 3 ( l ₁ → l ₂ ) By this operation, the lower punch 11 projects from the bottom surface of the forming frame 1 as shown in FIG. 3 and is pressure-bonded to the upper surface of the table. Then, the pressurizing device 9 and the forming frame elevating / lowering device 5 are raised, and the insertion device 6 is withdrawn as indicated by the arrow (see FIG. 3).

When the elevating cylinder 8 and the eccentric weight vibrator 10 are operated again and the pressurizing device is lowered to l ₀ → l ₂ → l ₃ to vibrate and pressurize the dough 2 (see FIG. 4), While being further pressed by the punch 3, the lower punch 11 enters the forming frame, and a shaped roof tile having a required shape is obtained (see FIGS. 4 and 5).

In the illustrated example, the upper and lower punches have entered the upper and lower surfaces of the forming frame. However, depending on the shape of the brick, the properties of the dough, etc., the upper and lower punches may be inserted into the forming frame. The degree can be appropriately determined.

Further, the molded brick can be taken out easily by disassembling the molding frame according to a conventional method. In the case of an integrally molded frame, the bricks molded by using a conventional deframer (not shown) may be extruded and taken out.
