Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cast iron casting forming, in particular to a nodular cast iron casting forming equipment. BACKGROUND

[0002] The nodular cast iron casting forming equipment is a complete set of equipment specially used for producing nodular cast iron castings, and the core goal is to obtain castings with spherical graphite, high strength, high toughness and good wear resistance by accurately controlling the process links of melting, spheroidizing, pouring and cooling.

[0003] In the sand pouring process of a large nodular cast iron casting forming equipment, the worker needs to hold the sand pouring pipe and adjust its position to align the opening with the sand pouring position on the top of the sand box. However, due to the large size of the metal model, the worker cannot complete the operation at a single position and needs to repeatedly adjust the body position and posture, which not only complicates the process but also seriously affects the work efficiency. At the same time, the worker needs to maintain a bent-over, arm-lifting posture for a long time during the operation, especially when handling large models, the posture duration is longer, which easily leads to muscle fatigue, further reducing work efficiency and operation accuracy. In the process of pouring molten iron into the sand mold, it is crucial to stably control the pouring speed of the molten iron. However, due to the large size of the container for pouring molten iron, it is difficult to accurately control the rotation speed by manually rotating the pouring bucket to tilt it to pour out the molten iron. If the tilting speed is too fast, the rapid flow of molten iron will suck in air to form pores and will also lift the sand mold to form sand inclusions, which not only reduces the quality of the castings but also poses a risk of being scalded by the worker being too close to the molten iron. If the speed is too slow, more oxidation films will be formed on the surface of the molten iron, causing the molten iron to flow out unevenly. Therefore, the present application provides a nodular cast iron casting forming equipment to meet the needs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a nodular cast iron casting forming equipment, which can quickly complete the sand pouring work by the worker standing on one side of the sand box body through the setting of the position adjusting mechanism and the angle adjusting mechanism, thereby reducing the labor intensity and significantly improving the sand pouring efficiency. The above settings can solve the problem of inconvenient manual operation in the production and casting process of existing large equipment.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] The utility model provides a nodular cast iron casting forming equipment, including operation platform, which is equipped with sand box body on, the top of sand box body is equipped with hanger, the bottom of hanger is equipped with ladle body, the top of sand box body is equipped with sand supply mechanism, one side of sand supply mechanism is installed with sand outlet pipeline, position adjusting mechanism is used for adjusting the position of the opening of sand outlet pipeline, position adjusting mechanism is connected with sand supply mechanism, angle adjusting mechanism is used for adjusting the inclination angle of ladle body, and angle adjusting mechanism is connected with position adjusting mechanism.

[0007] Optionally, the position adjusting mechanism comprises a first frame installed at the bottom of the sand supply mechanism, a second frame fixedly connected to one side of the first frame close to the sand outlet pipeline, a first connecting block fixedly connected to one end of the second frame away from the first frame, a first connecting frame installed at the bottom of the first frame, a rotating block rotatably connected to the first connecting frame, a handle fixedly connected to both sides of the rotating block, a first connecting rope installed at the bottom of the second frame, and a third connecting block fixedly connected to one end of the first connecting rope close to the second frame.

[0008] Optionally, the second frame and the third frame are integrally formed.

[0009] Optionally, a first weakened portion is formed at the top of the second frame, and the second frame is made of plastic material.

[0010] Optionally, the first connecting frame is in the shape of a hook, and a limiting sheet is fixedly connected to one end of the first connecting frame away from the first frame.

[0011] Optionally, threads are formed on the surface of the rotating block, anti-skid lines are arranged on the outer wall of the handle, and a plurality of concave portions and convex points are annularly and equidistantly arranged on the handle.

[0012] Optionally, the second frame and the third frame are both in the shape of an arc protruding towards the top, and the first frame is in the shape of a cross.

[0013] Optionally, the angle adjusting mechanism comprises a second connecting frame installed on the first frame, a pulley rotatably connected to the second connecting frame, a second connecting rope provided at the bottom of the pulley, a second connecting block fixedly connected to one end of the second connecting rope close to the ladle body, and a rotating handle installed on one side of the ladle body close to the second connecting block.

[0014] Optionally, the second connecting block is made of stainless steel and is in the shape matching that of the rotating handle.

[0015] Optionally, one side of the second connecting block is provided with a guide part, and a second weakening part is formed in the side of the second connecting block close to the guide part.

[0016] Compared with the prior art, the present application has at least the following beneficial effects:

[0017] In the above scheme, by arranging the position adjusting mechanism and the angle adjusting mechanism, the staff can quickly complete the sand pouring work by standing at one side of the sand box body, which not only reduces the labor intensity, but also significantly improves the sand pouring efficiency; and the staff can rotate the pouring bucket body at a safe distance to realize slow and stable rotation of the pouring bucket body, thereby ensuring that the molten iron flows into the sand box body at a constant speed, which not only guarantees the integrity of the sand mold in the sand box body, but also provides safety protection for the staff.

[0018] By arranging the first skeleton, the second skeleton and the first connecting rope in the position adjusting mechanism, the staff standing on one side close to the first skeleton can change the position of the sand outlet pipe opening by operating the handle, so that the sand outlet pipe opening can be accurately aligned with different sand pouring positions on the top of the sand box body. This operation mode enables the staff to complete the entire sand pouring work of the sand box body without moving the body and changing the position, which not only greatly reduces the labor intensity and makes the operation more convenient, but also effectively guarantees the efficiency of the sand pouring work.

[0019] By arranging the second connecting rope, the second connecting frame and the pulley in the angle adjusting mechanism, the staff can rotate the handle with both hands to realize the rotation of the pouring bucket body, and the staff is kept at a distance from the pouring bucket body, so the safety is effectively guaranteed. At the same time, by rotating the handle to control the rotation of the handle, the pouring bucket body can be kept in a slow and uniform inclined state, so that the molten iron in the pouring bucket body flows out and is injected into the specified position, thereby avoiding the damage of the sand mold in the pouring bucket body due to the rapid flow of the molten iron.

[0020] By arranging the second connecting block in the angle adjusting mechanism, the second connecting block can be more quickly installed on the handle by using the guidance of the guide part, and the position close to the second weakening part on the second connecting block deforms first during installation, which further makes the installation of the second connecting block more convenient and fast. After the second connecting block is installed on the handle, the part close to the second weakening part on the second connecting block deforms and rebounds, so that the opening of the second connecting block forms a squeezing limit on the handle, which further guarantees the stability of the installation of the second connecting block.

[0021] In summary, the present application not only enables the device to make the ductile iron casting forming work efficient and stable by the cooperation of the position adjusting mechanism, the angle adjusting mechanism and the components therein, but also reduces the labor force and guarantees the safety of the staff.

The devices can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0041] As Figure 1 and Figure 2As shown, the embodiment of the application provides a nodular cast iron casting forming equipment, which comprises an operation table 1, a sand box body 2 is arranged on the operation table 1, a hanging bracket 3 is arranged at the top of the sand box body 2, a pouring bucket body 4 is arranged at the bottom of the hanging bracket 3, a sand supply mechanism 5 is arranged at the top of the sand box body 2, and a sand outlet pipeline 6 is arranged on one side of the sand supply mechanism 5. Optionally, the operation table 1 is static, and the sand box body 2 is moved to the next station by an external driving device. The driving mechanism is a mature technology. Optionally, the sand box body 2 is composed of a positioning and closing mechanism, a fastening mechanism, a lifting and supporting mechanism and an exhaust and sand cleaning mechanism. The positioning and closing mechanism, the fastening mechanism, the lifting and supporting mechanism and the exhaust and sand cleaning mechanism are mature technologies, and thus the working principle and specific structure are not described in detail. Optionally, a guide rail frame is arranged at the top of the hanging bracket 3, a sliding block is arranged on the guide rail frame, the sliding block is connected with the hanging bracket 3, and the guide rail frame and the sliding block are manually pulled to make the hanging bracket 3 move along the guide rail. The guide rail frame and the sliding block are mature technologies, and thus the working principle and specific structure are not described in detail. The pouring bucket body 4 comprises a bucket body, a pouring nozzle, a bucket ear, a lifting shaft and a tilting and control mechanism. The bucket body, the pouring nozzle, the bucket ear, the lifting shaft and the tilting and control mechanism are mature technologies, and thus the working principle and specific structure are not described in detail. The sand supply mechanism 5 comprises a sand bin, a sand conveying system, a sand amount control system and a mounting mechanism. The sand bin, the sand conveying system, the sand amount control system and the mounting mechanism are mature technologies, and thus the working principle and specific structure are not described in detail. Therefore, the operation table 1, the sand box body 2, the hanging bracket 3, the pouring bucket body 4, the sand supply mechanism 5 and the sand outlet pipeline 6 are mature technologies, and thus the working principle and specific structure are not described in detail. A position adjusting mechanism is arranged on the sand supply mechanism 5 and used for adjusting the position of the opening of the sand outlet pipeline 6. An angle adjusting mechanism is arranged on the position adjusting mechanism and used for adjusting the inclination angle of the pouring bucket body 4. When the sand in the sand supply mechanism 5 is poured into the sand box body 2, a worker needs to hold the sand outlet pipeline 6 and adjust the position of the sand outlet pipeline 6 to make the opening of the sand outlet pipeline 6 align with the sand injection part at the top of the sand box body 2. However, due to the large size of the metal model, the worker cannot complete the sand injection at a single position and needs to repeatedly adjust the position and posture, which is complicated and seriously affects the work efficiency. The application of the position adjusting mechanism in the device enables the worker to complete the sand injection work quickly by standing at the side of the sand box body 2, which reduces the labor intensity and significantly improves the sand injection efficiency. In addition, the pouring speed of the molten iron into the sand box body 2 from the pouring bucket body 4 needs to be stably controlled. The previous manual rotation of the pouring bucket body 4 to make it tilt and pour out the molten iron is difficult to accurately control the rotation speed.Moreover, the workers are too close to the molten iron, and if the pouring bucket body 4 is tilted too fast, not only will the sand mold in the pouring bucket body 4 be damaged, but there is also a risk of being scalded; the device, through the cooperative operation of the angle adjusting mechanism and the position adjusting mechanism, enables the workers to rotate the pouring bucket body 4 at a safe distance, realizes the slow and stable rotation of the pouring bucket body 4, and thus ensures that the molten iron flows into the sand box body 2 at a uniform and slow speed, which not only guarantees the integrity of the sand mold in the sand box body 2, but also provides safety for the workers.

[0042] As shown in Figures 2 to 4 and Figures 7 to 10 , the position adjusting mechanism comprises a first skeleton 7 installed at the bottom of the sand supply mechanism 5, the first skeleton 7 is fixedly connected with a second skeleton 8 near one side of the sand outlet pipeline 6, the second skeleton 8 is fixedly connected with a first connecting block 9 at the end away from the first skeleton 7, the bottom of the first skeleton 7 is installed with a first connecting frame 13, the first connecting frame 13 is rotatably connected with a rotating block 14, both sides of the rotating block 14 are fixedly connected with hand grips 15, the bottom of the second skeleton 8 is installed with a first connecting rope 12, the first connecting rope 12 is fixedly connected with a third connecting block 23 at the end close to the second skeleton 8, the sand outlet pipeline 6 is a corrugated pipe, the third connecting block 23 is fixed on the side of the second skeleton 8 close to the first connecting block 9, the end of the first connecting rope 12 away from the third connecting block 23 is wound and fixed on the rotating block 14, the second skeleton 8, the first connecting rope 12 and the first skeleton 7 form a structure close to a triangle, the workers stand on the side close to the first skeleton 7, hold the two hand grips 15 and rotate, which can drive the rotating block 14 to rotate on the first connecting frame 13, and promote the first connecting rope 12 to wind more on the rotating block 14. During this process, the first connecting rope 12 will pull the second skeleton 8 to deform, and thus change the position of the opening of the sand outlet pipeline 6, so that it can accurately align different sand injection positions on the top of the sand box body 2. With this operation mode, the workers do not need to move their bodies and change positions, but only need to maintain a relaxed posture to complete the entire sand injection work of the sand box body 2, which not only greatly reduces the labor intensity and makes the operation more convenient, but also effectively guarantees the efficiency of the sand injection work.

[0043] Further, the second framework 8 is fixedly connected with the third framework 10 on both sides, thereby enhancing the stability of the second framework 8 and ensuring that the second framework 8 can return to the initial state under the action of external force. The second framework 8 and the third framework 10 are integrally formed, which is stable and convenient to produce and transport. The top of the second framework 8 is provided with the first weakening portion 11, which enhances the deformation ability of the second framework 8, so that the second framework 8 deforms first at the first weakening portion 11 under the action of external force. The second framework 8 is made of plastic material, which has good deformation ability. The first connecting frame 13 is in the shape of a hook, and the end of the first connecting frame 13 away from the first framework 7 is fixedly connected with the limiting sheet 19, so that the rotating block 14 and the handle 15 can be stably installed on the first connecting frame 13 for use. The surface of the rotating block 14 is provided with threads, so that the rotating block 14 has good anti-skid performance. The outer wall of the handle 15 is provided with anti-skid lines. A plurality of concave portions and convex points are arranged at equal intervals on the handle 15, so that the staff can stably hold the handle 15, which is convenient for the staff to rotate the handle 15 and prevents side slipping during work. The second framework 8 and the third framework 10 are both arc-shaped structures protruding towards the top, which makes the deformation trend of the second framework 8 and the third framework 10 better. The first framework 7 is in the shape of a cross, which is simple in structure and facilitates the orderly installation of various components on the first framework 7 for use.

[0044] As shown in Figures 3 to 8 , the angle adjusting mechanism comprises the second connecting frame 17 installed on the first framework 7. The second connecting frame 17 is rotatably connected with the pulley 18. The bottom of the pulley 18 is provided with the second connecting rope 16. The end of the second connecting rope 16 close to the pouring bucket body 4 is fixedly connected with the second connecting block 20. The side of the pouring bucket body 4 close to the second connecting block 20 is installed with the rotating handle 24. The second connecting frame 17 is in the shape of L. The pulley 18 is provided with a groove matched with the shape of the second connecting rope 16. The second connecting rope 16 is hung on the pulley 18 and forms an acute angle by bending. The second connecting block 20 is installed on the rotating handle 24 and is fixedly wound on the rotating block 14 away from the rotating handle 24. When the staff rotates the handle 15 with both hands, the length of the second connecting rope 16 wound on the rotating block 14 changes, thereby pulling and rotating the rotating handle 24, and finally realizing the rotation of the pouring bucket body 4. In this process, the staff keeps a far distance from the pouring bucket body 4, and the safety is effectively guaranteed. At the same time, the rotating handle 24 is controlled to rotate by rotating the handle 15, which can keep the pouring bucket body 4 in a slow and uniform inclined state, so that the internal iron can flow stably and be injected into the specified position, thereby avoiding the damage of the sand mold in the pouring bucket body 4 due to the too fast flow of the iron.

[0045] Further, the shape of the second connecting block 20 is matched with the shape of the handle 24, the second connecting block 20 is made of stainless steel material, the second connecting block 20 can be stably installed on the handle 24, one side of the second connecting block 20 is provided with a guide part 21, a second weakening part 22 is formed on the side of the second connecting block 20 close to the guide part 21, the guide part 21 can guide the second connecting block 20 to be more quickly installed on the handle 24, and the position close to the second weakening part 22 of the second connecting block 20 is preferentially deformed during installation, further making the installation of the second connecting block 20 more convenient and fast, after the second connecting block 20 is installed on the handle 24, the part close to the second weakening part 22 of the second connecting block 20 is deformed and rebounds, the opening of the second connecting block 20 is pressed and limited to the handle 24, and the stability of the installation of the second connecting block 20 is further ensured.

[0046] The working principle of the technical scheme provided by the application is as follows:

[0047] When the sand injection operation is performed on the sand box body 2, a worker first stands on one side close to the first frame 7, holds two handles 15 with both hands and rotates, drives the rotating block 14 to rotate on the first connecting frame 13, and promotes the first connecting rope 12 to be wound more on the rotating block 14. During this process, the first connecting rope 12 pulls the second frame 8 to deform, and further changes the position of the opening of the sand outlet pipe 6, so that the sand outlet pipe 6 can be accurately aligned with different sand injection positions on the top of the sand box body 2. After one sand injection is completed, the first connecting rope 12 wound on the rotating block 14 is released, the second frame 8 and the third frame 10 deform and rebound, and drive the sand outlet pipe 6 to reset, so as to perform the next sand injection operation on the sand box body 2. The operation table 1 is an operation platform, which can be static, driven by an external driving device to move the pouring bucket body 4 to the next station, or can be a conveyor belt with a driving mechanism, to move the sand box body 2 on it. The operation table 1 is not limited here, and the driving mechanism is a mature technology; in cooperation with the movement of the sand box body 2, the worker changes the opening position of the sand outlet pipe 6 by rotating the handle 15, without moving the body and changing the position, and only needs to maintain a relaxed posture to complete the entire sand injection work of the sand box body 2, greatly reducing the labor intensity, making the operation more convenient, and effectively ensuring the sand injection efficiency.

[0048] After the sand injection is completed, the sand box body 2 is moved to the next station to trim and reinforce the formed sand mold, and then is sent to the next station, the position of the pouring bucket body 4 is adjusted by using the existing control mechanism, the control mechanism is the mature technology at present, the sand box body 2 is aligned with the pouring bucket body 4, the staff near the first skeleton 7 guides the second connecting block 20 to be installed on the rotating handle 24 more quickly by means of the guide of the guide part 21, the position near the second weakening part 22 on the second connecting block 20 is deformed preferentially during the installation, and the installation of the second connecting block 20 is further facilitated. After the installation is completed, the part near the second weakening part 22 of the second connecting block 20 is deformed and rebounds, and the opening part of the second connecting block 20 forms extrusion limiting on the rotating handle 24; the initial position of the second connecting block 20 is at the bottom end of the rotating handle 24, which is beneficial to the rotating handle 24 being better rotated by the second connecting rope 16; the staff rotates the handle 15 with both hands, the length of the second connecting rope 16 wound on the rotating block 14 is changed, the rotating handle 24 is pulled and rotated, and finally the rotation of the pouring bucket body 4 is realized; during the process, the staff keeps a far distance from the pouring bucket body 4, and the safety is effectively guaranteed. Meanwhile, the rotating handle 15 is rotated to control the rotation of the rotating handle 24, the pouring bucket body 4 can be kept in a slow and uniform inclined state, the internal iron can be stably flowed out and injected into the specified position, and the sand mold in the pouring bucket body 4 is prevented from being damaged due to the too fast flowing of the iron. After the pouring is completed, the winding limiting of the second connecting rope 16 by the rotating block 14 is released, the pouring bucket body 4 is reset for the next pouring, and then the sand box body 2 is sent to the next station for subsequent operation. The device can assist manual operation, reduce the labor intensity, and guarantee the safety of the staff.
