Description

Technical Field

[0001] The invention relates to the technical field of casting, and in particular to a casting processing feeding mechanism and method. Background Art

[0002] Casting metal refers to the metal material used for pouring castings in casting production. It is an alloy composed of a metal element as the main component and other metal or non-metal elements. It is usually called a casting alloy. Traditional aluminum parts generally use a ratio of solid raw materials and liquid raw materials in the casting process, and then send them into the casting furnace for casting.

[0003] However, the existing solid raw materials are large in size, and the contact area between the solid raw materials and the liquid raw materials is small, which is not conducive to the melting of the solid raw materials, resulting in low casting efficiency. At the same time, in order to improve the purity of the castings, impurities on the raw materials are generally cleaned. Usually, tools are used manually to clean the impurities and dust on the outside of the aluminum raw materials to maintain the cleanliness of the aluminum parts. However, manual cleaning is inefficient and may even cause personal injury. In addition, the cleaned impurities and dust fall directly to the ground, making it difficult to clean the dust later.

[0004] Therefore, the present invention provides a casting processing feeding mechanism and method to solve the above problems. Summary of the invention

[0016] A method for casting a feeding mechanism, comprising the following steps:

[0017] Step 1: The personnel place the aluminum parts on the top surfaces of the four filter screens through the feeding port, turn on the power, and the controller starts the drive motor;

[0018] Step 2: The positioning shaft carries multiple stirring rods to stir the aluminum parts on the four filter screens, and the impurities and dust fall into the impurity chamber through the holes on the filter screens;

[0019] Step 3: The telescopic rod slides down along the sliding hole with the pull block, and the pull ring moves the four linkage rods. Each linkage rod swings down with the inner end of the corresponding screening box, and the aluminum part slides onto the receiving hopper through the gap below;

[0020] Step 4: The driving rack contacts the corresponding baffle. Due to the obstruction of the baffle, the driving rack will slide upward along the cavity of the collection box and mesh with the self-rotating gear to rotate.

The internal impurities of each screening box slide along the inclined surface of the impurity cavity to the inside of the receiving box;

[0021] Step 5: The impurities in the receiving box will slide into the discharge box below, and then the impurities will slide into the collection box through the discharge box;

[0022] Step 6: The driving shaft rotates rapidly with multiple crushing knives, and the crushed aluminum sheets fall on the top surface of the gear plate through the mesh. When the discharge hole coincides with the bottom port of the crushing cylinder, the crushed aluminum sheets quickly fall into the discharge port of the lower hopper through the discharge hole, and the aluminum parts finally fall onto the conveyor belt;

[0023] Step 7: The conveying motor drives the two rotating rollers and the conveyor belt to rotate, and the conveyor belt conveys the aluminum parts to the melting area for melting and casting.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. When the stirring rod stirs the aluminum parts, the impurities and dust attached to the aluminum parts will be shaken off, and the impurities fall into the impurity chamber and are collected, which accelerates the falling of impurities on the aluminum parts. At the same time, the conveyor belt can transport the aluminum parts to the melting area for melting and casting, which reduces the physical labor of the personnel, does not cause harm to the personnel, and improves the work efficiency.

[0026] 2. The driving shaft rotates rapidly with multiple crushing knives, which can break the aluminum parts. The broken aluminum sheets fall through the mesh. Since the broken aluminum sheets or aluminum blocks are small in size, they can accelerate the melting speed of the aluminum parts and make the aluminum parts melt more thoroughly, thereby improving the casting efficiency.

[0027] 3. Since the discharging circular hole and the bottom port of the crushing cylinder overlap intermittently, the intermittent quantitative discharging of aluminum sheets can be achieved, which improves the quality and weight of the casting and saves physical strength.

[0028] 4. Due to the obstruction of the baffle, the driving rack will slide upward along the cavity of the collection box and engage the rotating gear to rotate. The pressure spring is gradually compressed, and the rotating gear swings downward with the receiving box to an inclined angle. The internal impurities of each screening box slide along the inclined surface of the impurity cavity to the inside of the receiving box. The impurities inside the receiving box will slide into the discharge box below and finally slide into the collection box, so that the impurities can be collected and processed in a centralized manner to avoid the flying of impurities.

[0041] Refer to the following Figures 1 to 11 The embodiments of the present invention are described in detail. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0042] A casting processing feeding mechanism, such as Figure 1-Figure 4 , Fig. 9 As shown, it includes a support frame 1, and the number of support frames 1 is three, which improves the stability. A collar is fixedly installed on the top of the three support frames 1, and a processing cylinder 2 is fixedly installed inside the collar. The top of the processing cylinder 2 is a closed structure, and the bottom end is an open structure. A fixing ring 3 is fixedly installed above the inner wall of the processing cylinder 2, and a plurality of screening boxes 4 are evenly and rotatably installed on the inner wall of the fixing ring 3. The number of the screening boxes 4 is four, and the shape of the screening boxes 4 is a fan-shaped structure. The four screening boxes 4 can be combined into a circular structure, and a filter screen 5 is fixedly installed on the upper end of each of the screening boxes 4. There is an impurity cavity between the filter screen 5 and the inner bottom of the screening box 4, and a driving motor 6 is fixedly installed on the top of the processing cylinder 2. The driving motor 6 is installed at the bottom. The positioning shaft 7 at the end passes through the top of the processing cylinder 2 and extends to the inside of the processing cylinder 2. When the four filter screens 5 are on the same plane, the bottom surface of the positioning shaft 7 is not in contact with the filter screen 5. A plurality of stirring rods 8 are arranged on the positioning shaft 7. The inside of the processing cylinder 2 is provided with a driving device located below the fixing ring 3. A feeding rack 9 is arranged inside the supporting frame 1. Rotating rollers are rotatably installed at the front and rear ends of the feeding rack 9 respectively. A conveying belt 10 is installed between the two rotating rollers. A conveying motor is fixedly installed on the feeding rack 9. The rotating shaft of the conveying motor is coaxially fixedly connected with the rotating roller at the rear side. The conveying motor and the driving motor 6 are connected to the controller at the same time. The controller is connected to an external power supply. The top of the processing cylinder 2 is fixedly connected to the feeding port 11.

[0043] During use, personnel place smaller aluminum parts through the feeding port 11 onto the top surfaces of the four filter screens 5. When a certain amount of aluminum parts are placed, the power is turned on, the controller starts the drive motor 6, and the positioning shaft 7 carries a plurality of stirring rods 8 to stir the aluminum parts on the four filter screens 5. The aluminum parts will collide with each other, and the impurities and dust attached to the aluminum parts will be shaken off. The impurities and dust fall into the impurity chamber through the holes in the filter screen 5 and are collected. This can improve the cleanliness of the outer surface of the aluminum parts and the purity of the casting. When the impurities on the aluminum parts are cleaned, the drive device moves the four screening boxes 4 downward, and the four screening boxes 4 move away from each other, thereby opening a certain distance. At this time, each The screening boxes 4 form a downward tilt angle, and the aluminum parts will slide along the inclined surface of the filter screen 5 and through the gap to the conveyor belt 10. The conveying motor rotates with the two rotating rollers and the conveyor belt 10, and the conveyor belt 10 transports the aluminum parts to the melting area for melting and casting. When the aluminum parts on the four filter screens 5 fall onto the conveyor belt 10, the driving device pushes the four screening boxes 4 upward to restore them to their original state and continue to use them. Since the impurities fall into the impurity cavity, they will not fall to the ground, which improves the cleanliness of the bottom surface and reduces the physical labor of the personnel. The continuous stirring of the stirring rod 8 accelerates the falling of impurities on the aluminum parts, and will not cause harm to personnel, thereby improving work efficiency.

[0044] like Figure 3 , Figure 4 , Figure 6 As shown, the driving device includes a pulling ring 12, which is slidably mounted on the inner wall of the processing cylinder 2, and an upper fixing block 13 is fixedly mounted on the bottom end of each screening box 4, and lower fixing blocks 14 are evenly fixedly mounted on the pulling ring 12, and a linkage rod 15 is rotatably mounted on each upper fixing block 13, and the other end is rotatably mounted on the corresponding lower fixing block 14;

[0045] When in use, the pulling ring 12 moves with the four linkage rods 15, and each linkage rod 15 swings downward with the inner end of the corresponding screening box 4, so that the four screening boxes 4 move away from each other, thereby opening a certain distance, and each screening box 4 tilts downward at a certain angle. The aluminum parts will slide along the surface of the filter screen 5 and through the distance to the conveyor belt 10, so that each screening box 4 can be opened quickly, thereby improving the casting efficiency.

[0046] like Figure 2 , Figure 8 , Fig.10As shown, a receiving hopper 16 located below the pulling ring 12 is fixedly installed on the inner wall of the processing cylinder 2, and the tip of the receiving hopper 16 is set downward. A crushing cylinder 17 is fixedly penetrated through the tip of the receiving hopper 16. The crushing cylinder 17 is set up and down. A positioning rod 18 is fixedly installed on the inner end of the crushing cylinder 17. A driving shaft 19 is rotatably installed on the positioning rod 18. A plurality of crushing knives 20 are evenly fixedly installed on the driving shaft 19. A leakage net 21 is provided at the bottom end of the crushing cylinder 17. The mesh of the leakage net 21 is larger than the mesh of the filter 5.

[0047] When in use, the aluminum piece gradually slides down along the inclined surface of the filter screen 5, and slides onto the receiving hopper 16 through the gap below, and gradually slides down into the crushing cylinder 17 along the inner wall inclined surface of the receiving hopper 16. The driving shaft 19 rotates rapidly with multiple crushing knives 20, and the crushing knives 20 can break the aluminum piece, and the broken aluminum pieces fall down through the filter screen 21. Since the broken aluminum pieces or aluminum blocks are of smaller specifications, the melting speed of the aluminum piece can be accelerated, and the aluminum piece can be melted more thoroughly, thereby improving the casting efficiency.

[0048] like Figure 4 , Figure 6 , Figure 7 As shown, a collection box 22 is fixedly passed through the tip of the bottom end of each screening box 4, a material discharge port 23 is opened at the lower end of each collection box 22, a material receiving box 24 is rotatably mounted on the inner end of each material discharge port 23, and the material receiving box 24 can be completely closed inside the material discharge port 23, and a discharge device located below each material receiving box 24 is provided on the processing cylinder 2;

[0049] When in use, the positioning shaft 7 carries a plurality of stirring rods 8 to stir the aluminum parts on the four filter screens 5. The aluminum parts collide with each other, and the impurities and dust attached to the aluminum parts will be shaken off. The impurities and dust fall into the impurity cavity through the holes on the filter screen 5, and some of the impurities will fall into the inside of the receiving box 24, which can gradually improve the purity of the aluminum parts.

[0050] When the impurities on the aluminum parts are cleaned up, the pulling ring 12 moves with the four linkage rods 15, and each linkage rod 15 swings downward with the inner end of the corresponding screening box 4. The four screening boxes 4 move away from each other, thereby opening a certain distance. Each screening box 4 tilts downward at a certain angle, and the aluminum parts will fall downward along the tilted angle. At the same time, the internal impurities of each screening box 4 will also slide along the inclined surface of the impurity cavity to the inside of the collecting box 22 and the receiving box 24, without causing impurities to fall to the ground, thereby improving the cleanliness of the ground.

[0051] like Figure 1 , Figure 2 , Fig. 9As shown, a positioning block 25 is fixedly installed on the outer upper end of the processing cylinder 2, and a stabilizing block 26 is fixedly installed on the outer lower end of the processing cylinder 2. The positioning block 25 and the stabilizing block 26 are arranged correspondingly up and down. A linkage shaft 27 is rotatably installed between the positioning block 25 and the stabilizing block 26. A first sprocket group 28 is installed between the linkage shaft 27 and the positioning shaft 7. The first sprocket group 28 includes two first sprockets and a first chain. The first sprockets are coaxially fixedly installed on the positioning shaft 7 and the linkage shaft 27, respectively. The first chain is connected between the two first sprockets, and the first chain runs through the processing cylinder 2. A second sprocket group 29 is installed between the linkage shaft 27 and the driving shaft 19. The second sprocket group 29 includes two second sprockets and a second chain. The second sprockets are coaxially fixedly installed on the driving shaft 19 and the linkage shaft 27, respectively. The second chain is connected between the two second sprockets, and the second chain runs through the crushing cylinder 17 and the processing cylinder 2.

[0052] When the power is turned on, the controller starts the driving motor 6, and the positioning shaft 7 rotates with the stirring rod 8, the first sprocket set 28, the linkage shaft 27, the second sprocket set 29 and the driving shaft 19, thereby realizing the linkage coordination between the various components, improving convenience and saving costs.

[0053] like Figure 2 , Figure 4 As shown, a mounting block 30 is fixedly mounted on the outer end of the pulverizing cylinder 17, a gear plate 31 is rotatably mounted on the mounting block 30, the top surface of the gear plate 31 is in sliding contact with the bottom surface of the pulverizing cylinder 17, a discharging circular hole 32 is opened on the gear plate 31, a linkage gear 33 meshing with the gear plate 31 is coaxially fixedly mounted on the linkage shaft 27, the linkage gear 33 penetrates the processing cylinder 2, and a lower hopper 34 is fixedly penetrated on the bottom end of the processing cylinder 2;

[0054] When in use, the linkage shaft 27 rotates with the linkage gear 33, and the linkage gear 33 meshes with the gear plate 31 to rotate. The broken aluminum sheets pass through the sieve 21 and fall on the top surface of the gear plate 31 and are located inside the crushing cylinder 17. When the discharge hole 32 coincides with the bottom port of the crushing cylinder 17, the crushed aluminum sheets quickly fall into the discharge port of the lower hopper 34 through the discharge hole 32, and the aluminum pieces finally fall onto the conveyor belt 10. The conveying motor rotates with the two rotating rollers and the conveyor belt 10, and the conveyor belt 10 transports the aluminum pieces to the melting area for melting and casting. Since the discharge hole 32 coincides with the bottom port of the crushing cylinder 17 intermittently, intermittent quantitative unloading of aluminum sheets can be achieved, and the amount of aluminum sheets on the conveyor belt 10 can be basically the same, thereby improving the quality and weight of the casting, and there is no need for personnel to manually perform quantitative distribution of aluminum sheets, saving physical effort.

[0055] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Fig.10 As shown, the discharge device includes a discharge box 35, and four installation openings are evenly opened on the circumferential end of the processing cylinder 2, each installation opening is located directly below the corresponding receiving box 24, and an inclined discharge box 35 is fixedly installed inside each installation opening, the inner end of the discharge box 35 is arranged upward, and the outer end is arranged downward, a part of the discharge box 35 is arranged inside the processing cylinder 2, and the other part is arranged at the outer end of the processing cylinder 2, an upwardly arranged inclined rod 36 is fixedly installed on the inner end of each of the discharge boxes 35, and a baffle 37 is fixedly installed on the top of each of the inclined rods 36, A cavity is provided at the bottom of the tip of the collecting box 22, and a fixed shaft is rotatably installed on the inner wall of the cavity. The inner end of the receiving box 24 is fixedly installed on the fixed shaft, and the self-rotating gear 38 is coaxially fixedly installed on the fixed shaft. A driving rack 39 meshing with the self-rotating gear 38 is installed inside each cavity for sliding up and down. A pressure spring 40 is fixedly installed on the bottom end of each driving rack 39, and the top end of each pressure spring 40 is fixedly installed on the bottom surface of the collecting box 22. When the four screening boxes 4 are closed together and are on the same plane, the receiving box 24 is completely hidden inside the discharge port 23.

[0056] like Figure 1 As shown, a blanking box 41 is fixedly passed through the bottom of the outer end of each discharge box 35, and a collecting box 42 located below each blanking box 41 is fixedly installed on the outer end of the processing cylinder 2, and the bottom end of the blanking box 41 is fixedly passed through the inside of the collecting box 42, and the collecting box 42 is an annular structure, and a material taking door is arranged on the bottom end of the collecting box 42;

[0057] When in use, the pulling ring 12 moves the four linkage rods 15, and each linkage rod 15 swings downward with the inner end of the corresponding screening box 4, and the four screening boxes 4 move away from each other and gradually open a certain angle. At the same time, the driving rack 39 contacts the corresponding baffle plate 37. When the screening box 4 continues to move downward, due to the obstruction of the baffle plate 37, the driving rack 39 will slide upward along the cavity of the collection box 22 and mesh with the self-rotating gear 38 to rotate, the pressure spring 40 is gradually compressed, and the self-rotating gear 38 swings downward with the receiving box 24 to an inclined angle, and the internal impurities of each screening box 4 slide along the inclined surface of the impurity cavity into the inside of the receiving box 24. Since the receiving box 24 is inclined, the impurities in the receiving box 24 at this time will slide into the inside of the discharge box 35 below, and then the impurities will slide into the inside of the collection box 42 through the discharge box 41. The personnel can put the internal impurities into the appropriate area through the material taking door, so that the impurities can be collected and processed in a centralized manner, avoiding the flying of impurities, reducing air pollution and the work intensity of personnel;

[0058] When the four screening boxes 4 are gradually closed, the rebound force of the pressure spring 40 pushes the driving rack 39 to reset, and at the same time, the receiving box 24 is hidden in the unloading port 23.

[0059] like Figure 2 , Figure 3 As shown, a vertical sliding hole 43 is provided on the processing cylinder 2, and a pulling block 44 located inside the sliding hole 43 is fixedly installed on the pulling ring 12. An electric telescopic rod 45 is provided on the pulling block 44. The bottom end of the telescopic rod 45 passes through the corresponding discharge box 35 and is fixedly connected to the processing cylinder 2. The telescopic top end of the telescopic rod 45 is fixedly connected to the pulling block 44. The lower end of the linkage shaft 27 passes through the corresponding discharge box 35. The telescopic rod 45 is connected to the controller. The telescopic rod 45 can slide up and down along the sliding hole 43 with the pulling block 44, so as to open the four screening boxes 4 through the corresponding components. When the impurities inside the screening box 4 are not cleaned up, the telescopic rod 45 can be quickly retracted and retracted at this time, and the screening box 4 swings and vibrates up and down to shake off the impurities.

[0061] Step 1: The personnel place the aluminum parts on the top surfaces of the four filter screens 5 through the feeding port 11, turn on the power, and the controller starts the drive motor 6;

[0062] Step 2: The positioning shaft 7 carries a plurality of stirring rods 8 to stir the aluminum parts on the four filter screens 5, and the impurities and dust fall into the impurity chamber through the holes on the filter screens 5;

[0064] Step 4, the driving rack 39 contacts the corresponding baffle 37. Due to the obstruction of the baffle 37, the driving rack 39 will slide upward along the cavity of the collecting box 22 and engage the rotating gear 38 to rotate. The pressure spring 40 is gradually compressed, and the rotating gear 38 swings downward with the receiving box 24 to an inclined angle. The internal impurities of each screening box 4 slide along the inclined surface of the impurity cavity to the inside of the receiving box 24;

[0065] Step 5: The impurities in the receiving box 24 will slide into the discharge box 35 below, and then the impurities will slide into the collection box 42 through the drop box 41;

[0066] Step 6, the driving shaft 19 rotates rapidly with the multiple crushing knives 20, and the crushed aluminum pieces fall onto the top surface of the gear plate 31 through the screen 21. When the discharge hole 32 coincides with the bottom end of the crushing cylinder 17, the crushed aluminum pieces quickly fall into the discharge port of the lower hopper 34 through the discharge hole 32, and the aluminum pieces finally fall onto the conveyor belt 10;
