Description

Technical Field

[0001] The utility model relates to the technical field of iron ball production, in particular to a tipping device for forging and transferring iron balls. Background Art

[0002] After being forged by forging equipment, iron balls generally need to be transported to a cooling equipment by a transfer equipment for cooling down to meet the growth requirements of iron balls; for some iron balls made of high-carbon steel materials, high-alloy steel materials or in a partially annealed state, it is necessary to adopt the method of covering with sand for slow cooling to reduce internal stress and tissue defects and improve the processing performance of forgings.

[0003] In the existing operation process, a transfer trolley with sand inside is generally placed outside the forging equipment, and the staff places the forged iron balls in the sand for burial to meet the processing requirements.

[0004] However, there are great drawbacks in the traditional processing and burial process. During the operation, since the sand is a solid cooling medium, the falling height of the iron balls is limited. In the later stage of processing, the staff needs to use tools such as shovels to mix the sand; moreover, at the stage of tipping after cooling, all the mixed substances in the trolley need to be poured out to separate the iron balls from the sand to meet the requirements of subsequent storage and transportation. The above screening operation is usually carried out in an external equipment, and the transfer trolley needs to be lifted to a predetermined height. At the same time, the poured sand needs to be specially collected for recycling, which affects the overall processing efficiency. Content of the Utility Model

Detailed implementation manners

[0022] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manners.

[0024] The forged iron balls have good wear resistance and are widely used in various nodular equipment to crush materials.

[0025] After the iron balls are forged and formed by the forging equipment, they generally need to be transported to the cooling equipment by the transfer equipment for cooling to meet the growth needs of the iron balls; for some iron balls made of high-carbon steel materials, high-alloy steel materials or in a partially annealed state, it is necessary to adopt the method of covering with sand for slow cooling to reduce internal stress and tissue defects and improve the processing performance of the forgings.

[0026] In the existing operation process, a transfer trolley with sand inside is generally placed outside the forging equipment. Workers place the forged iron balls in the sand for burial to meet the processing requirements. However, there are significant drawbacks in the traditional processing and burial process. During the operation, since the sand is a solid cooling medium, the height that the iron balls can drop is limited. In the later stage of processing, workers need to use tools such as shovels to mix the sand. Moreover, during the stage of discharging the materials after cooling, all the mixed substances in the trolley need to be poured out, and the iron balls and sand need to be separated to meet the requirements of subsequent storage and transportation. The above screening operation is usually carried out in an external device, which requires lifting the transfer trolley to a predetermined height. At the same time, the sand poured out needs to be specially collected for recycling, which affects the overall processing efficiency.

[0027] To solve the above problems, specifically referring to the attached Figure 1 -attachment Figure 5 , a discharging device for iron ball forging transfer includes a transfer device 100 with an accommodation chamber. A screening device 200 is arranged in the accommodation chamber of the transfer device 100. Through the transfer device 100, the iron balls and the screening device 200 can be installed and stored. Through the screening device 200, the iron balls and the solid cooling medium can be screened. Here, the screening device 200 is installed in the transfer device 100, and the screened cooling medium can be accommodated through the accommodation chamber to achieve centralized storage.

[0028] Specifically, the screening device 200 is cylindrical and is rotationally connected to the inner wall of the transfer device 100. The screening device 200 includes a screening cylinder 210 and a shielding cover 220. The shielding cover 220 is sleeved outside the screening cylinder 210. Screening openings 211 are formed on the surface of the screening cylinder 210. A plurality of screening bars 212 are installed on the inner wall of the screening openings 211. A gap is formed between two adjacent screening bars 212 for the cooling medium to pass through. It should be noted here that the size between the two screening bars 212 is determined according to the size of the iron balls to be screened. The gap between them can allow the solid cooling medium to pass through, but can retain the iron balls inside to achieve the separation of the two.

[0029] A discharging opening 221 is formed on the surface of the shielding cover 220. The opening size of the discharging opening 221 is larger than the opening size of the screening openings 211. A locking workpiece 230 for locking and limiting is also arranged between the screening cylinder 210 and the shielding cover 220. Through the locking workpiece 230, the screening cylinder 210 and the shielding cover 220 can be limited to ensure that they are in a relatively stable state. Control the screening cylinder 210 and the shielding cover 220 to be in the screening state shown in the attachment Figure 5 At this time, the cooling medium can be screened to achieve the separation of the iron balls and the cooling medium. Control the screening cylinder 210 and the shielding cover 220 to be in the attachment Figure 4In the state shown, during this process, the screening opening 211 is in a state of being blocked by the shielding cover 220, and the iron balls and the cooling medium cannot be discharged, enabling mixing inside the screening cylinder 210, achieving efficient coverage of the iron balls, and ensuring that the iron balls are cooled as required.

[0030] In summary, through the above structural design, by controlling the screening cylinder 210 to be in a closed state through the shielding cover 220, the iron balls and the cooling medium inside can be fully mixed during the rotation of the screening device 200, eliminating the need for workers to operate with shovels, which is simple and convenient; when the screening cylinder 210 is controlled to be in the screening state, the sequential feeding of the cooling medium and the iron balls can be achieved, enabling their effective separation, facilitating subsequent storage and transportation. At the same time, the screened cooling medium can be centrally stored in the transfer device 100, further improving the processing efficiency.

[0031] It should be noted here that the common sand and gravel can still be selected as the cooling medium, which can slowly cool the coverage of the iron balls; at the same time, a handle 140 is installed on the side wall of the transfer device 100, and a pulley 130 is installed at the bottom, enabling the staff to move the entire device to different forging devices to meet the adaptability requirements for processing in the workshop.

[0032] Specifically, the screening baffle 212 is detachably connected to the screening opening 211. By removing the screening baffle 212, the loading and unloading of the iron balls can be achieved; at the same time, selecting different numbers of screening baffles 212 and adjusting the distance between the screening baffles 212 can meet the adaptive screening of iron balls of different sizes.

[0033] The first side wall of the screening cylinder 210 is rotationally connected to the inner wall of the transfer device 100 through a positioning rotating shaft 240. An electric control device can be installed outside the positioning rotating shaft 240. Through the electric control device, the electric rotation of the screening device 200 can be controlled to achieve automatic control, automatically completing the initial coverage and subsequent screening of the iron balls, further improving the overall processing efficiency.

[0034] Specifically, a feeding component 120 is installed on the second side of the screening cylinder 210. The feeding component 120 is fixedly connected to the transfer device 100, and the end of the feeding component 120 is rotationally connected to the screening cylinder 210. A feeding opening 213 is provided on the second side wall of the screening cylinder 210 for the feeding component 120 to pass through. By setting the above structure, the feeding of the iron balls can be achieved without removing the screening baffle 212, facilitating the operation of the staff.

[0035] The locking workpiece 230 here is preferably a locking bolt, and the surfaces of the screening drum 210 and the shielding cover 220 are installed with matching bolt holes. By rotating the locking bolts relative to different bolt holes, it can ensure that the screening drum 210 and the shielding cover 220 are in a stable state at different positions, avoiding relative movement between the screening drum 210 and the shielding cover 220, and ensuring the stability of the two in the mixing and screening states of iron balls; the existing bolts are simple to control and have a long service life.

[0036] A through unloading opening is provided on the side wall of the transfer equipment 100, and a dumping plate 110 is detachably installed inside the unloading opening. The dumping plate 110 here can be connected to the unloading opening by a hinge, so as to control the unloading opening to be in an open state, and the iron balls in the unloading state can be taken out; the dumping plate 110 here can be deflected inward to form an inclined channel for the iron balls to roll, thereby realizing the rapid discharge of the iron balls; at the same time, the dumping plate 110 inclined inward can separate the iron balls from the cooling medium at the bottom to avoid the two from mixing again.

[0037] A conveying device for pumping cooling medium is also provided inside the transfer equipment 100, and the end of the conveying device extends upward. By setting the above structure, the cooling medium at the bottom of the transfer equipment 100 can be pumped to the top position, and then re-put into the screening device 200 to be mixed with the iron balls and covered to achieve delayed cooling. The above structural design eliminates the need for manual transfer, thereby improving automation efficiency.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
