Abstract
Description
Technical Field
[0001] This invention relates to the field of casting processing, specifically to a device for processing castings of transmission machinery. Background Technology
[0002] As core components in various mechanical equipment, the machining accuracy, efficiency, and resource utilization rate of transmission machinery castings directly affect the overall performance of the equipment and the economic benefits of the manufacturing enterprise. Sand casting is one of the most widely used processes in the production and processing of transmission machinery castings. After the casting is formed, the sand mold must be crushed to remove the casting, and then the crushed sand mold undergoes further processing. Therefore, the crushing and recycling of sand molds is a crucial step in the processing of transmission machinery castings.
[0003] Currently, in the processing of castings for transmission machinery, sand mold crushing and sand recycling mostly employ segmented processing equipment. This involves using specialized crushing equipment to crush the sand mold, and then transferring the crushed sand to recycling equipment for further crushing, screening, and other processing. This segmented approach has several drawbacks: Firstly, the equipment is complex in structure, occupies a large area, and requires multiple machines to operate collaboratively. This not only increases equipment purchase and maintenance costs but also prolongs the processing flow, reduces the overall efficiency of casting processing, and fails to achieve integrated processing of sand mold crushing and sand recycling. Secondly, existing crushing equipment has poor adaptability. For sand molds of different sizes in transmission machinery castings, it is often necessary to replace the corresponding crushing components or adjust the equipment parameters, making operation cumbersome, lacking versatility, and unable to meet the processing needs of sand molds of diverse sizes, thus limiting the equipment's applicability.
[0004] Meanwhile, in the sand mold crushing and recycling process, existing equipment has poor control over the degree of crushing, resulting in uneven particle size of the crushed sand and some sand that cannot be directly recycled and reused, leading to low utilization rate of sand mold resources. A large amount of insufficiently recycled sand not only wastes resources but also requires additional processing, increasing environmental pressure and costs in the production process, thereby reducing the overall economic benefits of the enterprise. Furthermore, although some integrated processing equipment attempts to combine crushing and recycling functions, their structural design is unreasonable, resulting in either poor crushing effects affecting the quality of the extracted castings or excessive sand loss during recycling, failing to effectively solve the aforementioned technical problems. Summary of the Invention
[0005] The purpose of this invention is to provide a processing device for transmission machinery castings to solve the problems mentioned in the background art.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0030] Please refer to the attached drawings. A transmission machinery casting processing device is designed to achieve integrated processing of casting crushing, pulverizing, and screening. Its overall structure consists of two core platforms: a first processing platform 1 and a second processing platform 2, which are fixedly connected. These two platforms work together to complete the entire casting processing process. The first processing platform 1 serves as the main processing area, with a processing table surface 3 fixedly connected to its top. This processing table surface 3 provides a stable foundation for the installation of subsequent processing components. To provide structural support for the crushing operation, a processing beam 4 is fixedly connected to the processing table surface 3. The processing beam 4 is specifically equipped with crushing components 5 for the initial crushing of castings. A collection box 8 is also provided on the processing table surface 3 for placing casting molds and collecting crushed materials. Together, these form the core processing unit on the first processing platform 1.
[0031] The crushing assembly 5, as the core actuator of the device, consists of two sets, both driven by the same servo motor 7, thereby improving crushing efficiency and ensuring the balance of crushing force. Each crushing assembly 5 includes at least one reciprocating breaker hammer 6, which achieves reciprocating motion through a specific transmission structure, thereby impacting and crushing the castings in the collection box 8. Specifically, the transmission structure of the crushing assembly 5 consists of a slide rod 14, a crossbar 15, a second spring 16, a rotating disk 17, and arc-shaped teeth 18. The slide rod 14 is connected to the machining beam 4 in a longitudinal sliding fit, ensuring that the slide rod 14 can only move in the vertical direction, avoiding deviation that would affect the crushing accuracy. The crossbar 15 is fixedly connected to the top of the slide rod 14, and the breaker hammer 6 is connected below the crossbar 15, providing elastic support for the reset of the breaker hammer 6. The second spring 16 is also fixedly connected below the crossbar 15, and the slide rod 14 always abuts against the surface of the arc-shaped teeth 18 of the rotating disk 17 under the elastic force of the second spring 16.
[0032] The servo motor 7 serves as the power source for the crushing assembly 5. Its output shaft is fixedly connected to the rotating disk 17. The arc-shaped teeth 18 on the rotating disk 17 are the key structure for driving the breaker hammer 6 to move up and down. The arc-shaped teeth 18 consists of several stepped segments, forming a staggered tooth surface structure. When the servo motor 7 drives the rotating disk 17 to rotate, the arc-shaped teeth 18 rotate together. The bottom of the slide rod 14 always fits against the surface of the arc-shaped teeth 18 under the preload of the second spring 16. When the slide rod 14 is misaligned with the stepped segment of the arc-shaped teeth 18, the slide rod 14 loses the support force of the tooth surface and quickly pops down under the elastic force of the second spring 16, driving the crossbar 15 and the breaker hammer 6 below to move down synchronously, impacting and crushing the casting mold and castings in the collection box 8. When the high segment of the arc-shaped teeth 18 contacts the slide rod 14 again, it pushes the slide rod 14 to reset upward, compressing the second spring 16 to store elastic potential energy. This cycle repeats, realizing the continuous up-and-down reciprocating crushing action of the breaker hammer 6.
[0033] To adapt to the crushing requirements of castings of different specifications, the device is also designed with a height adjustment structure for the breaker hammer 6, specifically achieved through a sleeve 19, a screw 20, and a drive block 21. The sleeve 19 is fixedly connected to the lower part of the crossbar 15, and the screw 20 is threadedly connected inside the sleeve 19. The breaker hammer 6 is fixedly connected to the bottom of the screw 20, and the drive block 21 is fixedly connected to the outside of the screw 20. The operator can rotate the drive block 21 to rotate the screw 20 within the sleeve 19, changing the extension length of the screw 20 using the threaded transmission principle. This adjusts the initial distance between the breaker hammer 6 and the castings in the collection box 8, enabling flexible adjustment of the crushing depth and force, and improving the adaptability of the device.
[0034] The material collection box 8, serving as a material carrier and transfer component, not only holds the casting molds but also performs preliminary processing and guiding functions for the crushed materials. Several support rollers 9 are rotatably connected to its top. These support rollers 9 reduce friction between the casting molds and the top of the collection box 8, facilitating quick pushing or adjustment of the mold positions by operators and improving operational convenience. Since the material after preliminary crushing may contain excessively large particles, a crushing component 10 is specially installed inside the collection box 8 for secondary refining of the crushed material, ensuring the smooth progress of subsequent screening operations.
[0035] The crushing assembly 10 consists of a crushing motor 22, a driving gear 23, crushing shafts 24, driven gears, crushing blades 25, a crushing chamber wall 26, and a guide plate 27. The crushing motor 22 is fixed to the outer wall of the collection box 8, providing power output for the crushing operation. Its output shaft is fixedly connected to the driving gear 23. Two parallel crushing shafts 24 are rotatably connected to the corresponding positions on the side wall of the collection box 8. Each crushing shaft 24 has a driven gear fixedly connected to its end, and both driven gears mesh with the driving gear 23. When the crushing motor 22 starts, the driving gear 23 drives the two driven gears to rotate in opposite directions, thereby driving the two crushing shafts 24 to rotate synchronously in opposite directions. Several crushing blades 25 are fixedly connected to the outer side of the crushing shafts 24. The crushing blades 25 on the two crushing shafts 24 are arranged alternately, which can form a shearing and impact effect on the falling material, realizing secondary crushing of the material.
[0036] To improve the crushing effect and avoid material splashing, a crushing chamber wall 26 is provided on the outside of the crushing shaft 24. The crushing chamber wall 26 is fixed to the inside of the collection box 8 to form a relatively closed crushing space. At the same time, a guide plate 27 is also provided on the inside of the collection box 8. The guide plate 27 adopts an inclined design, which can accurately guide the material that falls to the bottom of the collection box 8 after preliminary crushing to the crushing area of the crushing component 10, ensuring that all materials undergo secondary crushing and avoiding the occurrence of missed crushing.
[0037] After secondary crushing, the material needs to be screened to separate particles that meet the specifications. This function is achieved by the screening component 12 on the second processing table 2. Several first springs 11 are fixedly connected to the top of the second processing table 2, and the screening component 12 is fixedly connected to the top of the first springs 11. The first springs 11 provide elastic support for the screening component 12, reducing the impact of vibration on the overall structure of the device during screening, while increasing the vibration amplitude of the screening component 12 and improving screening efficiency. Correspondingly, a discharge port 13 is opened on the side wall of the collection box 8. The discharge port 13 is directly opposite the screening component 12. The crushed material can be directly conveyed into the screening component 12 through the discharge port 13 without the need for an additional transfer device, simplifying the material flow path.
[0038] It is worth noting that a magnetic iron removal component is also installed at the discharge port 13. Since iron filings and other impurities may be mixed in during the processing of transmission machinery castings, the magnetic iron removal component can adsorb and remove ferromagnetic impurities in the material before the material is discharged from the collection box 8, so as to avoid impurities affecting the subsequent screening accuracy and the quality of the finished castings, and improve the processing reliability of the device.
[0039] The screening assembly 12 specifically consists of a screening box 28, a vibrating motor 29, a screen 30, a first discharge port 31, and a second discharge port 32. The screening box 28 serves as the supporting structure for the screening operation. The vibrating motor 29, fixedly connected to its bottom, provides power for the screening. Upon startup, it drives the screening box 28 and the internal screen 30 to vibrate synchronously, causing the material to tumble and stratify rapidly on the screen 30. The screen 30 is fixed inside the screening box 28, and different aperture sizes can be selected according to processing requirements to achieve graded screening of material particles. The bottom of the screening box 28 has two discharge ports. The first discharge port 31 communicates with the space below the screen 30 and is used to discharge fine particles that have passed through the screen 30; this material can be directly used for subsequent processing. The second discharge port 32 communicates with the space above the screen 30 and is used to discharge larger particles that have not passed through the screen 30; this material can be recycled to the collection box 8 for further crushing and pulverizing, achieving material recycling and reducing resource waste.
[0040] In summary, this transmission machinery casting processing device, through the coordinated operation of the first processing table 1 and the second processing table 2, and with the sequential operation of the crushing component 5, the pulverizing component 10 and the screening component 12, realizes the integrated processing of castings from initial crushing, secondary pulverizing to graded screening. At the same time, through the height adjustment structure, magnetic iron removal component and recycling design, the adaptability, processing accuracy and resource utilization of the device are further improved, which can effectively meet the high-efficiency processing requirements of transmission machinery castings.
[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
