Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to an automatic iron forging device for casting machines. Background Art

[0002] The casting machine is an important equipment for manufacturing metal castings. It injects molten metal into the cast iron mold. The molten iron in the cast iron mold runs through the chain belt and is cooled by cooling water to solidify into the casting of the desired shape. When the chain belt runs to the driving wheel of the machine head, it automatically falls off due to gravity and falls into the chute. However, in the actual operation process, the demoulding effect of the casting machine is not ideal, and the bread iron cannot fall off automatically. When casting, two employees need to manually knock the bread iron at the casting head to demould. The steam on site is large and the environment is poor. The manual knocking force of the personnel is small, the demoulding effect is poor, the efficiency is low, and the labor intensity of the personnel is high. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figures 1 to 6 The utility model provides an automatic iron forging device for a casting machine, which is arranged at the head of the casting machine. A sprocket 200 is arranged at the head of the casting machine. A chain is wound around the sprocket 200. A plurality of cast iron molds 300 are arranged on the chain. The iron forging device 100 includes a rotating shaft 1 and a plurality of pins 2. The number of the pins 2 is consistent with the number of cast iron molds 300 that can be arranged on the entire circle of the sprocket 200, so that each time the sprocket 200 rotates through a position of a cast iron mold 300, the pins 2 can push the striking mechanism 3 to move once. For example, Figure 3 As shown, 16 cast iron molds 300 can be arranged around the entire sprocket 200 (in fact, because the cast iron molds are pulled by the chain, only 10 cast iron molds 300 surround the outer side of the sprocket 200, as shown in FIG. Figure 1 and Figure 2 As shown), the number of the pins 2 is also 16. The rotating shaft 1 is arranged above the sprocket 200 at the head of the casting machine, and the rotating shaft 1 is rotatably connected to the casting machine. The plurality of pins 2 are divided into two groups, and the two groups of pins 2 are respectively fixed on the side walls of the sprocket 200 at the head of the casting machine, and each group of pins 2 is centered on the axis of the sprocket 200, and the annular array is arranged on the side wall of the sprocket 200;

[0022] The side wall of the rotating shaft 1 is fixedly connected with a knocking mechanism 3 and two rocker arms 4. The two rocker arms 4 are respectively arranged on both sides of the rotating shaft 1, and each of the rocker arms 4 extends to the pin shaft 2 and contacts one of the pin shafts 2. When the sprocket 200 at the head of the casting machine rotates, the pin shaft 2 pushes the rocker arm 4 to lift up, so that the knocking mechanism 3 is lifted; and each time the sprocket 200 rotates through the position of the cast iron mold 300, the pin shaft 2 pushes the rocker arm 4 to swing up once.

[0023] The knocking mechanism 3 includes a hammer assembly 31 and a connecting arm 32 fixed to the rotating shaft 1, wherein the connecting arm 32 is fixedly connected with a first connecting assembly 33 and a second connecting assembly 34, wherein an angle is formed between the first connecting assembly 33 and the second connecting assembly 34, and a cavity 35 for accommodating the hammer assembly 31 is respectively reserved between the first connecting assembly 33 and the second connecting assembly 34, wherein the hammer assembly 31 is connected to the first connecting assembly 33 and the second connecting assembly 34 by bolts and nuts, wherein the lower end of the hammer assembly 31 extends to the outside of the cavity 35, and the hammer assembly 31 is composed of a plurality of hammer units 311, each of which is provided with a fixing hole, wherein the bolt passes through the fixing hole so that the hammer unit 311 is connected to the first connecting assembly 33 and the second connecting assembly 34. According to the demand for knocking force, the weight of the hammer assembly 31 can be adjusted by increasing or decreasing the number of hammer units 311 connected to the first connecting assembly 33 and the second connecting assembly 34 to adapt to different knocking forces.

[0024] Specifically, the first connecting component 33 includes two first connecting bars 331, and the two first connecting bars 331 are respectively fixed on both sides of the connecting arm 32. The second connecting component 34 includes two second connecting bars 341, and the two second connecting bars 341 are respectively fixed on both sides of the connecting arm 32. There is a spacing between the two first connecting bars 331 and between the two second connecting bars 341 to form a cavity 35 for accommodating the hammer head assembly 31.

[0025] Specifically, the number of the pins 2 in each group is 16.

[0026] A specific application of this application is:

[0027] The sprocket 200 rotates, driving the chain to move, so that the cast iron mold 300 moves from the casting position to the head of the casting machine. When the sprocket 200 rotates, one of the pins 2 holds the swing rod 4. As the sprocket 200 rotates, the swing rod 4 gradually swings upward. The swing of the swing rod 4 rotates the shaft 1, so that the knocking mechanism 3 is lifted synchronously. When the pin 2 rotates to the position where the swing rod 4 is disengaged, the knocking mechanism 3 falls due to its own gravity. At this time, the hammer assembly 31 knocks the bread iron in the cast iron mold 300 to demold the bread iron. When the knocking mechanism 3 knocks on the bread iron, the swing rod 4 is reset, and as the sprocket 200 continues to rotate, the other pin 2 continues to hold the swing rod 4, and continues to lift the knocking mechanism 3. This cycle is repeated, so that the knocking mechanism 3 knocks the bread iron on the cast iron mold 300 one by one, thereby achieving the demolding effect.

[0028] According to the demand for the striking force, the weight of the hammer assembly 31 can be adjusted by increasing or decreasing the number of hammer units 311 connected to the first connecting assembly 33 and the second connecting assembly 34 to adapt to different striking forces. For example, when the striking force needs to be increased, the number of hammer units 311 is increased in the cavity 35 accommodating the hammer assembly 31, so that the total weight of the hammer assembly 31 increases, and then when the striking mechanism 3 falls, the force applied by the hammer assembly 31 to the bread iron increases. Conversely, the number of hammer units 311 is reduced in the cavity 35 accommodating the hammer assembly 31, so that the force applied by the hammer assembly 31 to the bread iron decreases.

[0029] By arranging the device at the head of the casting machine, during the rotation of the casting machine, the pin shaft supports the rocker arm, the rotating shaft rotates, and the knocking mechanism is lifted synchronously. When the pin shaft rotates to the position where the rocker arm is disengaged, the knocking mechanism falls under the action of its own weight, and the hammer head assembly knocks the bread iron to demould, thereby reducing the labor of personnel and improving the demoulding effect and efficiency.

[0030] Furthermore, the hammer assembly of the utility model is composed of a plurality of hammer units. According to the requirements of the striking force, the utility model can adjust the weight of the hammer assembly by increasing or decreasing the number of hammer units to adapt to different striking forces.

[0031] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
