Description

Technical Field

[0001] The invention relates to the technical field of casting processing, and in particular to a sand falling and crushing integrated machine and a use method thereof. Background Art

[0002] In the foundry industry, sand removal is an important process. Its main purpose is to separate the molding sand and casting in the mold, which refers to the operation of separating the casting from the sand mold. Its purpose is to remove the molding sand and core sand on the surface of the casting, laying the foundation for subsequent cleaning, processing and use. The quality of sand removal directly affects the quality and production efficiency of the casting. Incomplete sand removal of the casting will have many effects on the quality and subsequent processing of the casting. Specifically: Incomplete sand removal will cause defects such as sand removal, pores, and cracks on the surface of the casting, which not only reduces the aesthetics of the casting, but also may cause the performance of the casting to decline in actual use, and the mechanical properties will be damaged: If there are defects such as sand scars, inclusions, burrs, etc. inside the casting, it will directly affect the strength of the casting, toughness, corrosion resistance and other key mechanical properties, thereby affecting the service life and safety of the casting, and the overall quality will decline: Incomplete sand removal may also cause defects such as cavities and shrinkage holes inside the casting, which will further reduce the overall quality of the casting, increase the scrap rate, and may cause unnecessary troubles for subsequent processing and use. Impact on subsequent processing: Castings with incomplete sand removal may encounter more difficulties in subsequent processing, such as difficulty in ensuring processing accuracy and reduced processing efficiency, which will increase production costs and cycles. During the casting process, sand particles may condense on the surface of the casting due to various reasons. This phenomenon is generally called sticking sand. Sticking sand not only affects the appearance quality of the casting, but also may have an adverse effect on the performance and service life of the casting. First of all, breaking the agglomerated sand particles is one of the key steps in the post-processing of castings. During the casting process, sand particles may condense on the surface or inside of the casting for various reasons, which not only affects the appearance quality of the casting, but also may have a negative impact on the performance and service life of the casting. By breaking these agglomerated sand particles, impurities and irregular parts on the surface of the casting can be effectively removed, making the surface of the casting smoother and smoother, meeting the requirements of subsequent processing or use. Secondly, breaking the agglomerated sand particles helps to recycle and reuse the waste generated in the casting process. A large amount of waste sand and waste slag will be generated in the production of castings. If these waste materials are not properly handled, they will not only occupy a large amount of space, but also may pollute the environment. By breaking up these agglomerated sand particles, they can be converted into reusable materials for making new castings or as raw materials for other processes, thus realizing the recycling of resources and reducing production costs. This also helps to reduce environmental pollution, so the quality of sand falling and subsequent sand processing are particularly important. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-7The present invention provides a technical solution: a sand-falling and crushing integrated machine, comprising a machine body 1, a top plate 12 is installed on the top of the machine body 1, and four sides of the upper surface of the top plate 12 are provided with material dropping openings 7, a sand-falling assembly 3 is installed on the surface of the top plate 12, a panel 10 is installed on the top of the sand-falling assembly 3, and clamping assemblies 6 are installed on the front and rear parts of the panel 10, the inner cavity of the machine body 1 is divided into an upper and lower part, and a grinding assembly 8 and a crushing assembly 9 are provided, two bottom plates 11 are movably installed on the bottom of the machine body 1, and a control assembly 5 is installed on the front surface of the machine body 1, and the control assembly 5 is connected to the bottom plate 11.

[0026] The body 1 is the outer shell of the all-in-one machine, which is a load-bearing structure used for structural loading. The top plate 12 is installed with the sand-falling component 3, and the dropping port 7 allows the sand particles shaken off by the sand-falling component 3 to fall into the interior of the body 1. The operation of the sand-falling component 3 drives the panel 10 to swing, so that the casting is swung to shed sand. The sand particles after sand falling are firstly ground by the grinding component 8, and then fall into the bottom plate 11 of the body 1 and are crushed by the crushing component 9. The control component 5 controls the two bottom plates to open and discharge the crushed sand particles, thereby forming an integration of sand falling and sand particle crushing. The vibration and swinging of the sand-falling component 3 can allow the casting to shake off the sand particles to the greatest extent under the action of the swinging inertia while being vibrated.

[0027] In some embodiments, the sand falling assembly 3 includes a carrier 35, vibration motors 31 are installed on both sides of the carrier 35, a servo motor 32 is installed at the bottom center of the carrier 35, the output end of the servo motor 32 is fixedly connected to a boss 33, a lever 34 is fixedly connected to the boss 33, and a universal joint assembly 4 is installed on the top of the carrier 35.

[0028] The rotation of the servo motor 32 drives the convex handle 33 to rotate, and the convex handle 33 drives the lever 34 to rotate. The convex handle 33 is slightly raised, and the lever 34 is slightly inclined, which will produce a longitudinal drop swing during the rotation. The carrier 35 is used to encompass the entire sand falling assembly 3. The vibration motor 31 transmits shock waves to the panel 10 to shake the castings on its surface.

[0029] In some embodiments, the universal joint assembly 4 includes a mounting ring 43, the outer wall of the mounting ring 43 is divided into four equal parts and equidistantly installed with connecting tubes 42, a mounting seat 44 is provided at the center of the mounting ring 43, the front and rear side walls of the mounting seat 44 are fixedly connected with a first connecting rod 41, the tops of both ends of the carrier 35 are fixedly connected with a second connecting rod 45, the second connecting rod 45 and the first connecting rod 41 are plugged into the connecting tubes 42 at corresponding positions, the top of the mounting seat 44 is fixedly connected with a panel 10, and the bottom of the mounting seat 44 is connected to the lever 34 through a bearing.

[0030] When the lever 34 rotates, the mounting seat 44 is rotated. As the lever 34 continues to rotate in a circular shape, the mounting seat 44 is driven to swing with a circular height difference. In order to avoid jamming, the movable connection between the first connecting rod 41, the second connecting rod 45 and the connecting tube 42 ensures that the mounting seat 44 can swing smoothly, thereby swinging the panel 10.

The two output ends of each cylinder 61 are fixedly connected to a support rod 62, the outer wall of the support rod 62 is sleeved with a sleeve 64, and the outer wall of the sleeve 64 is fixedly connected to a clamping plate 63.

[0032] The clamping assembly 6 fixes the installation of the casting on the panel 10, the sleeve 64 rotates on the outer wall of the support rod 62, allowing the clamping plate 63 to initially dock with the casting, and the cylinder 61 drives the support rod 62 to retract, allowing the clamping plate 63 to clamp the casting on the surface of the panel 10 to fix it.

[0033] In some embodiments, the control component 5 includes a cylinder seat 51 and a rotating shaft 53, the rotating shaft 53 is movably connected to the body 1, and the base plate 11 is fixedly connected to the outer wall of the rotating shaft 53, a telescopic cylinder 52 is installed inside the cylinder seat 51, the output end of the telescopic cylinder 52 is fixedly connected to a connecting frame 56, a ring 54 is fixedly connected to the outer wall of the rotating shaft 53, a transmission rod 55 is fixedly connected to the outer wall of the ring 54, and the transmission rod 55 is movably connected to the connecting frame 56.

[0034] The extension of the telescopic cylinder 52 drives the transmission rod 55 to rotate through the connecting frame 56, and the transmission rod 55 drives the ring 54 and the rotating shaft 53 to rotate, thereby controlling the rotation of the bottom plate 11. After the bottom plate 11 is opened, the crushed sand particles can flow out for discharge.

[0035] In some embodiments, the grinding assembly 8 includes a motor 81, which is installed at the bottom of the top plate 12. The output end of the motor 81 is fixedly connected to one end of a rotating rod 82, the outer wall of the rotating rod 82 is fixedly connected to a grinding cone 83, and the other end of the rotating rod 82 is installed with a grinding assembly 9.

[0036] The rotation of the motor 81 drives the rotating rod 82 and the grinding cone 83 to rotate. After the grinding cone 83 rotates, the sand particles in the gap between the grinding cone 83 and the machine body 1 are ground. Due to the characteristics of the cone, the sand blocks and sand particles are ground from large to small.

[0037] In some embodiments, the crushing assembly 9 includes a mounting frame 91 , which is connected to the rotating rod 82 , and a grinding roller 93 is movably mounted on the mounting frame 91 via a connecting shaft 92 .

[0038] The roughly crushed sand particles fall onto the surface of the bottom plate 11 , and the mounting frame 91 drives the roller 93 to rotate along with the rotating rod 82 , and the roller 93 crushes the sand particles to completely crush them.

[0039] In some embodiments, roller 93 is a solid steel roller, the weight of which can more completely break up the sand particles.

[0040] In some embodiments, the casting is placed on the surface of the panel 10, the cylinder 61 is retracted, the sleeve 64 is moved to drive the clamp 63 to make initial contact with the casting, the cylinder 61 drives the four-point clamp 63 to clamp the casting, the rotation of the servo motor 32 drives the lever 34 to rotate, the lever 34 drives the mounting seat 44 to rotate, the mounting seat 44 drives the casting on the panel 10 to swing, the grinding assembly 8 and the crushing assembly 9 are crushed, and the control assembly 5 controls the bottom plate 11 to open the discharge.

[0041] In some embodiments, the swing speed of the panel 10 is controlled by the rotation speed of the servo motor 32 .

[0042] Working principle: the casting is placed on the surface of the panel 10, the sleeve 64 rotates on the outer wall of the support rod 62, so that the clamping plate 63 and the casting are preliminarily docked, the cylinder 61 drives the support rod 62 to retract, so that the clamping plate 63 clamps the casting on the surface of the panel 10 to fix it, and the vibration motor 31 works to transmit shock waves to the panel 10 to shake the casting on its surface, and the rotation of the servo motor 32 drives the convex handle 33 to rotate, and the convex handle 33 drives the lever 34 to rotate, and when the lever 34 rotates, the mounting seat 44 is driven to rotate, and with the continuous circumferential rotation of the lever 34, the mounting seat 44 is driven to perform a circumferential height difference swinging action. In order to avoid jamming, the movable connection between the first connecting rod 41 and the second connecting rod 45 and the connecting tube 42 ensures that the mounting seat 44 can be shaken smoothly The swinging action swings the panel 10, and the drop port 7 makes the sand particles shaken off by the sand falling component 3 fall into the interior of the machine body 1. The rotation of the motor 81 drives the rotating rod 82 and the grinding cone 83 to rotate. After the grinding cone 83 rotates, the sand particles in the gap between the machine body 1 are ground. Due to the characteristics of the cone, the sand blocks and sand particles are ground from large to small. The roughly ground sand particles fall to the surface of the bottom plate 11 after being ground. The mounting frame 91 drives the grinding roller 93 to rotate with the rotating rod 82, and the grinding roller 93 grinds the sand particles to completely crush them. The extension of the telescopic cylinder 52 drives the transmission rod 55 to rotate through the connecting frame 56, and the transmission rod 55 drives the ring 54 and the rotating shaft 53 to rotate, thereby controlling the rotation of the bottom plate 11. After the bottom plate 11 is opened, the crushed sand particles are allowed to flow out for discharge.
