Accordingly, as the piston of the rotary cylinder 34 moves forward or backward, the rotary piece 33, the first rotary shaft 31, and the rotary block 32 rotate left or right together. At this time, the rotation angle of the rotary block 32 is rotated at an angle between about 0 ° to 90 °.

The second rotating unit 4 includes a second rotating shaft 41 and a motor 42.

The second rotary shaft 41 passes through the lower portion of the vertical panel 322 and is installed on the vertical panel 322, and the front end is coupled to the rotary plate 51. Here, the balance weight 43 may be installed behind the second rotary shaft 41. A description thereof will be described later.

The motor 42 has a motor shaft installed on the front surface of the vertical panel 322 through the upper front surface of the vertical panel 322. At this time, the motor 42 and the second rotary shaft 41 are connected by a chain 45 and a sprocket 44 or a combination of a belt (not shown) and a pulley (not shown). The rotating shaft 41 rotates. Here, the motor 42 may be a step motor or a sub-motor, and the like, and the motor 42 and the second rotating shaft 41 may be connected by a plurality of gears (not shown).

The slide moving part 5 includes a rotating plate 51, a reciprocating guide 52, a reciprocating moving piece 53, and a reciprocating cylinder 54.

The rotating plate 51 is provided in a substantially disk shape, the rear surface of which is perpendicular to one end of the second rotating shaft 41, that is, perpendicular to the second rotating shaft 41. Accordingly, when the second rotating shaft 41 rotates, the rotating plate 51 also rotates together.

The reciprocating guide 52 is disposed in parallel with the second rotary shaft 41 in the form of two elongated rods and penetrates the rotary plate 51 so as to protrude forward from the rotary plate 51. Accordingly, when the rotating plate 51 rotates, the reciprocating guide 52 also rotates together.

The reciprocating piece 53 is a cylindrical shape with a rear opening, and a plurality of protruding pieces are provided on both sides, and the plurality of protruding pieces are fitted into the reciprocating guide 52.

Since the balance weight 43 is provided with the slide moving part 5 and the bucket 7 in front of the second rotating shaft 41 in front, the weight can be directed to the front of the second rotating shaft 41. Therefore, in order to balance the weight, the counterweight 43 is provided at the rear of the second rotation shaft 41 so as to correspond to the weight formed in front of the second rotation shaft 41. Accordingly, by forming a balanced weight of the front and rear of the second rotary shaft 41, the present invention can be prevented from inclined or the second rotary shaft 41 is bent.

In the present invention, all the parts operating by rotating may be installed with a bearing (B) for easy rotation. In addition, all the cylinders used in the present invention is a hydraulic or pneumatic cylinder. Since this is a natural configuration for those skilled in the art, a detailed description thereof will be omitted.

The control unit 4 'is connected to the forging device 2' and the automatic injection device 3 ', and the upper mold 2a, the lower mold 2b, the plunger 2c, etc. of the forging device 2'. It controls the operation and the operation of the automatic injection device 3 'and the removal mobile device 5'. That is, the operation speed of the automatic injection device 3 ', the operation speed and pressure of the forging device 2', and the operation speed of the stripping moving device 5 'are controlled, and their operation order is controlled. In particular, the control unit 4 'adjusts the pressing force of the plunger 2c applied during molding of the product in the forging device 2', and receives the information measured by the pressure sensor 2d installed in the plunger 2c, and measures the The applied information is compared with a preset pressure value to adjust the pressing force of the plunger 2c. For example, the general forging device 2 'controls the operation of the forging device 2' by controlling the pressure of the fluid for operating the mold by the control unit 4 '. In the process of applying pressure to the hydraulic loss due to the loss of fluid, and the volume of the plunger (2c) and the mold expands in accordance with the temperature change, the length and width deviation occurs, and accordingly the actual plunger (2c) applied during the molding The deviation of the required pressure becomes large. In other words, the quality of the product varies according to the pressure applied during the molding of the product, the pressure is not uniform, the quality deviation between the products increases, and the defective rate also increases.

However, in order to minimize this error, the present invention provides a pressure sensor 2d in the middle of the plunger 2c for measuring the required pressure at which the plunger 2c actually applies the molten metal, and controls it from the pressure sensor 2d. 4 'receives the information and compares the preset pressure value to control the operation of the plunger 2c. At this time, the controller 4 'controls the operation of the plunger 2c by comparing the value of the pressure value corresponding to the weight of the plunger 2c disposed above the pressure sensor 2d with a preset pressure value. Accordingly, by minimizing the defective rate while reducing the quality gap between the products, it is possible to increase the quality of the product, it is possible to improve the productivity.

The stripping moving device 5 'takes out the finished product from the forging device 2' and transfers it to a conveyor (not shown). Accordingly, by automating all processes in the production of the product, it is possible to prevent safety accidents due to dangerous work in advance, and to increase the production speed to improve product productivity and product quality.

Hereinafter, the operating state of the automatic injection device (3 ') in the automatic forging apparatus according to an embodiment of the present invention will be described in detail.

As shown in FIGS. 5 to 7, in order for the automatic injection device 3 ′ of the present invention to pump molten metal out of the molten metal, the lifting cylinder 23 is operated to raise and lower the lifting block 22 and the reciprocating cylinder. 54 is operated so that the reciprocating piece 53 protrudes.

When the reciprocating piece 53 protrudes and moves toward the molten metal, the bucket 7 is positioned at the upper part of the molten metal. At this time, the rotating cylinder 62 is operated to rotate the rotating piece 61 while the bucket 7 rotates downward. (See Figure 8)

After the bucket 7 rotates downward, the lifting cylinder 23 is operated to lower the lifting block 22 (see FIG. 9).

When the elevating block 22 descends, the bucket 7 is locked into the molten metal, and the elevating block 22 is raised while rotating the bucket 7 upward by operating the rotation cylinder 62 and the elevating cylinder 23 simultaneously. Let's do it. Accordingly, the bucket 7 spreads the molten metal contained in the molten metal (see FIGS. 10 and 11).

When the molten metal is pumped into the bucket 7, the reciprocating cylinder 54 is operated to transfer the reciprocating piece 53 to the rear, and after the reciprocating piece 53 is transferred to the rear, the rotary cylinder 34 is operated. (See FIG. 12)

When the rotary cylinder 34 operates, the rotary block 32 and the bucket 7 rotate on the plane to the left. Then, the reciprocating cylinder 54 is operated to advance the reciprocating moving piece 53 so that the bucket 7 is located at the injection port of the forging device 2 '. (See FIGS. 13 and 14).

When the bucket 7 reaches the upper portion of the injection hole of the forging device 2 ', the motor 42 is operated to rotate the second rotating shaft 41. When the second rotary shaft 41 rotates, the slide moving part 5 and the bucket 7 rotate, and as the bucket 7 rotates, the molten metal contained in the bucket 7 is poured into the inlet of the forging device 2 'and melted. Inject the metal (see FIGS. 15 and 16).

When the molten metal injection is completed, the motor 42 is operated to rotate the bucket 7 to its original position, and when the bucket 7 is restored to its original position, the reciprocating cylinder 54 is operated to transfer the reciprocating piece 53 to the rear. Let's do it.

Hereinafter, the working process of the automatic forging device according to an embodiment of the present invention will be described.

When the molten metal reaches the set temperature in the molten metal heat retention device 1 ', the automatic injection device 3' pours out the molten metal and pours it into the lower mold 2b of the forging device 2 '.

After the automatic injection device 3 'pours molten metal into the lower mold 2b of the forging device 2' and is out of the forging device 2 ', the upper mold 2a of the forging device 2' is lowered. , Plunger 2c rises.

After the plunger 2c pressurizes the molten metal to a predetermined pressure, after a predetermined time, the upper mold 2a rises, and the plunger 2c rises to release the product from the lower mold 2b.

When the stripping moving device 5 'catches the detached product, the plunger 2c descends to exit the product, and the stripping moving device 5' transfers the product to the conveyor.

This process is repeated to produce the product automatically.

Therefore, the present invention can reduce the manufacturing time and improve the productivity by supplying the molten metal contained in the molten metal to the forging device 2 'within a predetermined time by repeatedly performing the above operating procedure. In addition, since the operation is performed in the same time from the first stage operation to the last stage operation, the molten metal having the same temperature is supplied to the forging device 2 'every time the product is manufactured, thereby minimizing the variation between the products and improving the quality. At the same time, the failure rate can be minimized. In addition, since the automatic injection device (3 ') of the present invention instead of a dangerous job is replaced, it is possible to prevent a safety accident for human injury, and to always supply a certain amount of molten metal to the forging device (2'), which is a defective product. This can be prevented from occurring. Furthermore, by preventing the mistake of pouring molten metal onto the lower mold 2b of the forging device 2 ', the forging device 2' can be prevented from malfunctioning and the life of the forging device 2 'can be extended. .

In addition, the present invention by installing the third rotary part 6 in the reciprocating moving piece 53, only when the bucket (7) to move when the molten metal is pumped out, the molten metal can be pumped out with a minimum of operation to minimize the accident rate have. That is, when discharging molten metal, which is a dangerous operation, the other components of the apparatus move only in the stationary state without moving the bucket 7, thereby minimizing malfunctions and accidents and thus saving energy. The area can be minimized to minimize interference with obstacles.

In addition, by measuring the required pressure applied to the molten metal by the plunger 2c, the controller 4 'adjusts the pressure of the plunger 2c, thereby minimizing the defect rate while reducing the quality gap between the products, and furthermore, By automating, safety accidents can be prevented due to dangerous work, and product quality and productivity can be improved.
