Description

Technical Field

[0001] This utility model belongs to the field of grinding technology for industrial and mining castings, and in particular relates to a processing equipment for industrial and mining castings. Background Technology

[0002] Mining and industrial castings are cast parts used in industrial and mining equipment. These castings generally need to withstand large loads, pressures, or special environmental conditions. They are usually produced from metals such as steel, iron, and aluminum through casting processes and are used in various mechanical equipment and mining tools. After molten metal is poured into a mold and cooled and solidified to form the initial shape of the casting, the casting often needs to be polished after demolding to remove unwanted parts such as gates, risers, and flash.

[0003] Existing processing equipment, such as the mining casting processing equipment disclosed in Chinese announcement number CN216228553U, still has the following technical problems in the grinding process of mining castings:

[0004] During the grinding process, a large frictional force is generated between the surface of the casting and the grinding wheel or belt, which causes the temperature of the grinding wheel or belt to rise in a local area. This further leads to a higher temperature of the metal chips produced during grinding. When the temperature rises, these metal chips become softer and more sticky due to melting. As a result, the metal chips produced during grinding tend to adhere to the grinding wheel or belt. When the grinding wheel or belt contacts the casting for grinding, the chips attached to it can cause scratches, indentations or local damage to the surface of the casting, affecting the precision and appearance of the industrial casting.

[0005] Although existing processing equipment can provide appropriate cooling and lubrication to the grinding area during the grinding process, such as spraying cutting fluid onto the grinding area, the close contact between the casting and the grinding tool at the grinding area prevents the cutting fluid from flowing to the contact area between the workpiece and the grinding tool. Heat still accumulates in these areas, causing the temperature to rise. This can lead to thermal damage or deformation of the casting during the grinding process, reducing the processing quality of the casting. Utility Model Content

[0006] The purpose of this invention is to address the problems mentioned in the background art by providing a mining casting processing equipment that can periodically strike the inner wall of the abrasive belt during the grinding process, making it difficult for metal debris to adhere to the grinding surface of the abrasive belt.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A type of industrial and mining casting processing equipment, comprising:

[0009] The frame has a drive rod and two transmission rods arranged in a triangular pattern rotatably connected to its upper end. Rotating rollers are fixedly connected to the drive rod and the two transmission rods, and a sanding belt is sleeved between the three rotating rollers.

The telescopic end of the second telescopic rod is fixedly connected to the bottom end of the corresponding fixed block. An application block is installed on one of the fixed blocks, and the application block is equipped with application bristles. A second motor for driving the guide rod to rotate is installed on the other fixed block.

[0013] Preferably, the side plate is provided with a wetting mechanism for use with the coating mechanism, which is used to periodically wet the coating brush bristles with cutting fluid and then coat the sanding belt after wetting. The wetting mechanism includes a guide gear fixedly connected to a guide rod. A trapezoidal tooth groove is fixedly connected to the side wall of the side plate near the guide gear. The guide gear and the trapezoidal tooth groove mesh with each other. The fixed block on which the coating block is installed is provided with a hinge seat. A rocker arm is hinged to the hinge seat. A damping bearing is provided at the hinge position between the rocker arm and the hinge seat. The coating block is fixedly connected to the rocker arm. An installation block is also fixedly connected to the fixed block on which the coating block is installed. A rotating shaft is rotatably connected through the installation block. A bevel gear set is provided at the end of the rotating shaft and the hinge shaft of the rocker arm that are close to each other. A fifth gear is fixedly connected to the end of the rotating shaft away from the bevel gear set. Two helical racks that mesh with the fifth gear are symmetrically arranged on the coating platform. The helical racks are fixedly connected to the upper end of the coating platform by a support rod. A storage frame for storing cutting fluid is fixedly connected to the coating platform.

[0014] Preferably, when the guide rod moves at the bottom of the trapezoidal guide groove, the brush bristles on the application block are inside the storage frame.

[0015] Preferably, the upper end of the frame is provided with a rotating mechanism for driving the casting to rotate to achieve full grinding of the casting. The rotating mechanism includes a U-shaped plate fixedly connected to a U-shaped plate that is slidably connected to the upper part of the frame in a horizontal direction. Rotating blocks are rotatably connected through the upper and lower side walls of the U-shaped plate. The rotating blocks extend into the U-shaped plate and are fixedly connected to an electric telescopic rod. A clamping block is fixedly connected to the telescopic end of the electric telescopic rod. A first gear is fixedly connected to the rotating block extending out of the U-shaped plate. A rotating rod is rotatably connected through the upper and lower side walls of the U-shaped plate. A second gear that meshes with the first gear is fixedly connected to both ends of the rotating rod. A third motor for driving the rotating rod to rotate is fixedly connected to the outer wall of the U-shaped plate.

[0016] Preferably, the upper end of the frame is further provided with a pushing mechanism for periodically separating the casting and the sand belt. The pushing mechanism includes a slider fixedly connected to the outer wall of the U-shaped plate. The upper end of the frame is slidably connected to a slide rail in the horizontal direction. The slider is slidably connected to the slide rail in the vertical direction. A hydraulic cylinder for driving the slide rail and controlled by a time relay is fixedly connected to the frame.

[0017] Preferably, both ends of the slider are rotatably connected to rollers, and the upper end of the frame is fixedly connected to two symmetrically arranged guide rails through a second support plate. The guide rails have multiple protrusions in a linear array, and the rollers move along the upper end of the guide rails at corresponding positions.

[0018] Compared with existing technologies, the advantages of this mining casting processing equipment are:

[0019] 1. This utility model, by setting up a striking mechanism, enables two sector gears to periodically mesh with spur racks during the rotation of the drive rod. This causes the two spur racks to periodically move closer to each other and, under the elastic force of the spring, periodically strike the inner wall of the abrasive belt. This prevents metal debris from adhering to the grinding surface of the abrasive belt during the grinding process, thus avoiding scratches, indentations, or localized damage to the surface of the castings when these debris come into contact with them again. This ensures the precision and appearance of the castings.

[0020] 2. This utility model, by setting up an application mechanism, allows the guide rod to rotate via a second motor during the grinding process. This causes the guide gear on the guide rod to move along the trapezoidal tooth groove, further driving the guide rod to move along the trapezoidal guide groove. Under the action of the fifth gear, helical rack, and bevel gear set, the application brush bristles periodically enter the storage frame. After the application brush bristles are further wetted by the cutting fluid, the application block and application brush bristles rise up, periodically applying the cutting fluid to the abrasive belt. Since the abrasive belt is constantly conveying and grinding the casting, the cutting fluid can cool and lubricate the contact area between the casting and the abrasive belt, preventing heat accumulation and avoiding defects such as thermal damage or deformation of the casting, thus improving the processing quality of the casting.

[0021] 3. This utility model, by setting up a pushing mechanism, periodically controls the hydraulic cylinder to retract and extend during the grinding process through a time relay. During this process, the roller moves along the guide rail, and under the action of the protrusion on the guide rail, the slider undulates periodically within the guide rail, thereby causing the U-shaped plate and the fixed industrial casting inside it to vibrate periodically. This ensures that the debris adhering to the surface of the industrial casting is also cleaned during the grinding process, further preventing defects such as scratches caused by debris during the grinding process.

[0030] The following embodiments are for illustrative purposes only and are not intended to limit the scope of this invention.

[0031] Example: Refer to Figures 1 to 7 A type of industrial and mining casting processing equipment, comprising:

[0032] The upper end of the frame 1 is rotatably connected to a drive rod 11 and two transmission rods 12 arranged in a triangular pattern. Rotating rollers 13 are fixedly connected to the drive rod 11 and the two transmission rods 12. A sanding belt 14 is sleeved between the three rotating rollers 13.

[0033] Specifically, the upper end of the frame 1 is also provided with a grinding mechanism 3, which is used to continuously convey the sand belt 14 to perform grinding work on the casting. The grinding mechanism 3 includes a chain drive assembly disposed between the drive rod 11 and two transmission rods 12. The lower end of the frame 1 is provided with a first motor for controlling the rotation of the drive rod 11.

[0034] During the grinding process, the first motor drives the drive rod 11 to rotate, and further drives the transmission rod 12 to rotate through the chain transmission assembly, which enables the three rotating rollers 13 to rotate synchronously, thereby realizing the cyclic movement of the sand belt 14 along a fixed triangular trajectory. The grinding effect on the industrial casting is achieved through the continuous movement of the sand belt 14. This grinding method can avoid prolonged contact between the industrial casting and the grinding tool, and avoid heat accumulation that could cause thermal damage and deformation to the industrial casting.

[0035] The striking mechanism 2 is used to continuously strike the sanding belt 14 during the grinding process. The striking mechanism 2 includes a sector gear 21 fixedly connected to the upper end of the drive rod 11. There are two sector gears 21 arranged symmetrically. Two first support plates 22 are fixedly connected to the upper end of the frame 1. A first telescopic rod 23 is fixedly connected to the first support plate 22. A moving block 24 is fixedly connected to the telescopic end of the first telescopic rod 23. The moving block 24 is elastically connected to the side wall of the first support plate 22 by a spring 25. A rack 26 is fixedly connected to the moving block 24. The two sector gears 21 periodically mesh with the two racks 26. An extension rod 27 is fixedly connected to each of the two racks 26. An impact roller 28 is fixedly connected to the part of the extension rod 27 that extends into the sanding belt 14. The two impact rollers 28 abut against the inclined parts on both sides of the sanding belt 14.

[0036] In existing technologies, during the grinding process, significant friction occurs between the casting surface and the grinding wheel or belt, leading to localized temperature increases and stronger adhesion of metal chips. This results in metal chips easily adhering to the grinding wheel or belt, causing scratches, indentations, or localized damage to the casting surface. This invention addresses this issue by incorporating a striking mechanism 2. During the rotation of the drive rod 11, two sector gears 21 periodically mesh with a rack 26, causing the racks 26 to periodically move closer to each other. Under the elastic force of the spring 25, the racks periodically strike the inner wall of the abrasive belt 14. This prevents metal chips from adhering to the grinding surface of the abrasive belt 14, thus avoiding scratches, indentations, or localized damage to the casting surface when these chips re-enter the casting, ensuring the casting's precision and appearance.

[0037] A coating mechanism 4 is provided at the inclined positions on both sides of the sanding belt 14 on the frame 1. It is used to apply cutting fluid to the sanding surface of the sanding belt 14 before sanding. The coating mechanism 4 includes a coating platform 41 fixedly connected to the upper end of the frame 1. A side plate 42 is fixedly connected to the coating platform 41. A trapezoidal guide groove 43 is opened on the side plate 42. A guide rod 44 is movably connected through the trapezoidal guide groove 43. Fixed blocks 45 are rotatably connected to both ends of the guide rod 44. A strip-shaped limiting groove 46 is opened on both sides of the coating platform 41 located on the side plate 42. A second telescopic rod 47 is slidably connected in the strip-shaped limiting groove 46. The telescopic end of the second telescopic rod 47 is fixedly connected to the bottom end of the corresponding fixed block 45. A coating block 48 is installed on one of the fixed blocks 45 and the coating block 48 is provided with coating bristles. A second motor 49 for driving the guide rod 44 to rotate is provided on the other fixed block 45.

[0038] Specifically, the fixing block 45 with the coating block 48 installed is one of the two fixing blocks 45 that is closer to the sanding belt 14, while the fixing block 45 with the third motor 67 is the other of the two fixing blocks 45.

[0039] Specifically, the output end of the third motor 67 extends into the interior of the fixed block 45 and is fixedly connected to the guide rod 44, thus enabling the guide rod 44 to rotate.

[0040] Specifically, a portion of the trapezoidal guide groove 43 is fixedly connected to the upper end of the frame 1 via an L-shaped rod to ensure the guiding effect of the trapezoidal guide groove 43 on the guide rod 44.

[0041] Specifically, the trapezoidal guide groove 43 ensures that the guide gear 51 is always engaged with the trapezoidal tooth groove 52, while the strip-shaped limiting groove 46 and the second telescopic rod 47 ensure that the fixed block 45 will not rotate during the movement of the guide rod 44 along the trapezoidal guide groove 43, thus ensuring the stability of the second motor 49 and the subsequent wetting mechanism 5.

[0042] The side plate 42 is provided with a wetting mechanism 5 for use with the coating mechanism 4. This mechanism periodically wets the coating brush bristles with cutting fluid and then coats the sanding belt 14 with the fluid, improving the lubrication and cooling effect on the sanding belt. The wetting mechanism 5 includes a guide gear 51 fixedly connected to the guide rod 44. A trapezoidal toothed groove 52 is fixedly connected to the side wall of the side plate 42 near the guide gear 51. The guide gear 51 and the trapezoidal toothed groove 52 mesh with each other. A hinge seat 53 is provided on the fixing block 45 on which the coating block 48 is installed. A rocker arm 54 is hinged to the hinge seat 53, and a resistance is provided at the hinge position between the rocker arm 54 and the hinge seat 53. The coating block 48 is fixedly connected to the bearing and the rocker arm 54. The mounting block 45 on which the coating block 48 is installed is also fixedly connected to the mounting block 55. The rotating shaft 56 is rotatably connected through the mounting block 55. The end of the rotating shaft 56 and the hinge of the rocker arm 54 that are close to each other is provided with a bevel gear set 57. The end of the rotating shaft 56 away from the bevel gear set 57 is fixedly connected to the fifth gear 58. Two helical racks 59 that mesh with the fifth gear 58 are symmetrically arranged on the coating platform 41. The helical racks 59 are fixedly connected to the upper end of the coating platform 41 by a support rod. A storage frame 510 for storing cutting fluid is fixedly connected to the coating platform 41.

[0043] Specifically, when the guide rod 44 moves at the bottom of the trapezoidal guide groove 43, the brush bristles on the application block 48 are inside the storage frame 510.

[0044] Specifically, the damping bearing can introduce resistance between the hinge shaft and the hinge seat 53, and this resistance is greater than the sum of the weight of the smear block 48 and the smear bristles themselves and the friction force when the smear bristles on the smear block 48 come into contact with the sanding belt 14, so that the smear block 48 can only change angle under the action of the fifth gear 58 and the helical rack 59, and cannot rotate naturally.

[0045] In the existing technology, due to the close contact between the casting and the grinding tool at the grinding position, the cutting fluid cannot flow to the contact area between the workpiece and the grinding tool, and heat will still accumulate in these areas, causing the temperature to rise and thus causing thermal damage or deformation of the casting during the grinding process. This utility model sets up a coating mechanism 4, which can drive the guide rod 44 to rotate through the second motor 49 during the grinding process, so that the guide gear 51 on the guide rod 44 can move along the trapezoidal tooth groove 52, and further drive the guide rod 44 to move along the trapezoidal guide groove 43.

[0046] During the process of the guide rod 44 moving from the bottom to the top of the trapezoidal guide groove 43, the rotating shaft 56 will rotate at a certain angle under the action of the fifth gear 58 and the helical rack 59, and drive the hinge shaft and the rocker arm 54 to rotate 90° under the action of the bevel gear set 57. Here, the damping bearing will prevent the hinge shaft and the rocker arm 54 from rotating naturally after rotating 90°. Since the length of the helical rack 59 is constant, the hinge shaft and the rocker arm 54 will rotate 90° each time, so that the rocker arm 54 and the application block 48 can change from a vertical downward angle to a horizontal angle towards the sanding belt 14, so that the application brush bristles on the application block 48 can be closely attached to the sanding belt 14. Furthermore, under the action of the damping bearing, the angle between the rocker arm 54 and the application block 48 remains unchanged when the guide rod 44 moves along the top of the trapezoidal guide groove 43, so that the application brush bristles on the application block 48 can move horizontally to apply cutting fluid to the grinding surface of the sanding belt 14.

[0047] As the guide rod 44 moves from the top to the bottom of the trapezoidal guide groove 43, the rotating shaft 56 rotates 90° in the opposite direction under the action of the fifth gear 58 and the helical rack 59 on the other side. This causes the applicator block 48 to change from a horizontal angle towards the sanding belt 14 to a vertical downward angle. This allows the applicator bristles on the applicator block 48 to swing into the storage frame 510. Furthermore, under the action of the damping bearing, the angle between the swing rod 54 and the applicator block 48 remains constant as the guide rod 44 moves along the bottom of the trapezoidal guide groove 43, thus allowing the applicator bristles on the applicator block 48 to... The coating block 48 moves horizontally within the storage frame 510, wetting the coating brush bristles so that they periodically enter the storage frame 510. After the coating brush bristles are further wetted by the cutting fluid, the coating block 48 and the coating brush bristles rise, periodically applying the cutting fluid to the abrasive belt 14. Since the abrasive belt 14 is constantly conveying and grinding the casting, the cutting fluid can continuously cool and lubricate the contact area between the casting and the abrasive belt 14, preventing heat accumulation, preventing thermal damage or deformation defects in the casting, and improving the processing quality of the casting.

[0048] The upper end of the frame 1 is provided with a rotating mechanism 6, which is used to drive the casting to rotate in order to achieve full grinding of the casting. The rotating mechanism 6 includes a U-shaped plate 61 fixedly connected to the upper part of the frame 1 in a horizontal direction. The upper and lower side walls of the U-shaped plate 61 are rotatably connected with rotating blocks 62. The rotating blocks 62 extend into the U-shaped plate 61 and are fixedly connected with an electric telescopic rod 63. The telescopic end of the electric telescopic rod 63 is fixedly connected with a clamping block. The rotating blocks 62 extend out of the U-shaped plate 61 and are fixedly connected with a first gear 64. The upper and lower side walls of the U-shaped plate 61 are rotatably connected with a rotating rod 65. The two ends of the rotating rod 65 are fixedly connected with a second gear 66 that meshes with the first gear 64. A third motor 67 is fixedly connected to the outer wall of the U-shaped plate 61, which drives the rotating rod 65 to rotate through the electric gear.

[0049] Specifically, the output end of the first motor is fixedly connected to a third gear, and the part of the rotating rod 65 located inside the U-shaped plate 61 is fixedly connected to a fourth gear that meshes with the third gear. This is a common gear transmission method, so it will not be described in detail in this application.

[0050] Before grinding, the electric telescopic rod 63 controls the two clamping blocks to approach each other and clamp them at the center of the upper and lower end faces of the casting. During the continuous conveying of the sand belt 14, the rotating rod 65 can be driven to rotate by the third motor 67, and further driven to rotate the rotating block 62 under the action of the first gear 64 and the second gear 66, so that the electric telescopic rod 63 and the clamping blocks rotate synchronously, thereby allowing the casting to rotate and achieving comprehensive grinding of its peripheral sidewalls.

[0051] The upper end of the frame 1 is also provided with a pushing mechanism 7, which is used to periodically separate the casting and the sand belt 14. The pushing mechanism 7 includes a slider 71 fixedly connected to the outer wall of the U-shaped plate 61. The upper end of the frame 1 is slidably connected to a slide rail 72 in the horizontal direction. The slider 71 is slidably connected to the slide rail 72 in the vertical direction. A hydraulic cylinder 73 is fixedly connected to the frame 1 for driving the slide rail 72 and controlled by a time relay. Specifically, a signal can be sent to the time relay through a separately set controller (not shown in the figure). After receiving the action signal, the time relay starts the hydraulic cylinder 73 after a delay. Since the controller and the time relay are both existing mature technologies, they are not described in detail in this application.

[0052] Specifically, both ends of the slider 71 are rotatably connected to rollers 74, and the upper end of the frame 1 is fixedly connected to two symmetrically arranged guide rails 75 through the second support plate. The linear array portion of the guide rails 75 has multiple protrusions, and the rollers 74 move along the upper end of the guide rails 75 at the corresponding positions.

[0053] Specifically, the sanding belt 14 here is a cloth-based sanding belt, which has a certain degree of elasticity and is often used for sanding different materials such as metal, wood, plastic and glass.

[0054] During use, the hydraulic cylinder 73 pushes the U-shaped plate 61 and the casting fixed inside it, causing the casting to move towards the sand belt 14 and exert a large degree of pressure on the sand belt 14. Since the sand belt 14 has a certain elasticity, it ensures the contact grinding effect of the sand belt 14 on castings of different shapes and models.

[0055] It is worth mentioning that this method is not only suitable for grinding cylindrical castings, but also for grinding other regular-shaped castings such as rectangular and hexagonal ones. Because the industrial castings can approach and squeeze the abrasive belt 14 to a greater extent under the action of the hydraulic cylinder 73, when grinding castings of other shapes, the peripheral walls of the castings of other shapes can always be in contact with the abrasive belt 14 when rotating, thereby ensuring the grinding effect on industrial castings and improving the applicability.

[0056] It should also be noted that during the grinding process, the hydraulic cylinder 73 can be periodically controlled to retract and extend via a time relay. By periodically moving the casting and the abrasive belt 14 away from each other, the temperature between the casting and the abrasive belt 14 can be prevented from becoming too high, thus maintaining the surface quality of the casting. At the same time, during the periodic retraction and extension of the hydraulic cylinder 73, the roller 74 moves along the guide rail 75. Under the action of the protrusion on the guide rail 75, the slider 71 undulates periodically within the guide rail 72, thereby causing the U-shaped plate 61 and the casting fixed therein to vibrate periodically. This also removes the debris adhering to the surface of the casting during the grinding process, further preventing defects such as scratches caused by debris during the grinding process.

[0057] The functional principle of this utility model can be explained through the following operation methods:

[0058] Before grinding, the electric telescopic rod 63 controls the two clamping blocks to approach each other and clamp them at the center of the upper and lower end faces of the casting. Then, the hydraulic cylinder 73 drives the U-shaped plate 61 and the casting to approach the abrasive belt 14, so that the casting can squeeze the abrasive belt inward and tightly adhere to the abrasive belt 14. The first motor is turned on, driving the drive rod 11 to rotate, and further driving the transmission rod 12 to rotate through the chain drive assembly, so that the three rotating rollers 13 rotate synchronously. The grinding effect of the casting is achieved by the continuous delivery of the abrasive belt. The third motor 67 is turned on, driving the rotating rod 65 to rotate, driving the rotating block 62 to rotate, so that the casting can rotate and achieve full grinding of its peripheral sidewalls.

[0059] During the rotation of the drive rod 11, it can drive the two sector gears 21 to mesh with the rack 26 periodically, so that the two racks 26 periodically move closer to each other and periodically strike the inner wall of the sanding belt 14 under the elastic force of the spring 25, so that the metal chips during the grinding process are not easy to adhere to the grinding surface of the sanding belt 14.

[0060] During the grinding process, the second motor 49 is turned on, driving the guide rod 44 to rotate. This causes the guide gear 51 on the guide rod 44 to move along the trapezoidal tooth groove 52, further driving the guide rod 44 to move along the trapezoidal guide groove 43. As the guide rod 44 moves from the bottom to the top of the trapezoidal guide groove 43, the swing arm 54 and the coating block 48 change from a vertical downward angle to a horizontal angle towards the abrasive belt. This allows the coating brush bristles on the coating block 48 to move horizontally to apply cutting fluid to the grinding surface of the abrasive belt 14. As the guide rod 44 moves from the top to the bottom of the trapezoidal guide groove 43, the coating block 48 changes from a horizontal angle towards the abrasive belt 14 to a vertical downward angle. This allows the coating brush bristles on the coating block 48 to move horizontally within the storage frame 510 to wet the coating brush bristles. Since the abrasive belt 14 is continuously conveying and grinding the casting, the cutting fluid can continuously cool and lubricate the contact area between the casting and the abrasive belt 14.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
