Description

Technical Field

[0001] The present invention relates to the technical field of die casting cleaning equipment, and in particular to an integrated spray cleaning system for die castings. Background Art

[0002] In the production process of die-casting parts, spray cleaning is a crucial process link. After die-casting parts are formed, their surfaces often retain various pollutants such as lubricating oil, cutting oil, metal powder, particulate matter, dust, fingerprints, etc. These pollutants not only affect the appearance quality of die-casting parts, but may also have adverse effects on their mechanical properties, corrosion resistance and service life. In order to remove these pollutants and ensure that die-casting parts meet the required cleanliness and quality standards, spray cleaning technology is widely used.

[0003] Patent application number CN202420994826.3 discloses a rotary cleaning machine for die-castings of an electric control box. The bottom cabinet has an equipment cabin and a water collecting tank isolated from each other. The cleaning cabinet is installed on the top of the equipment cabin. The bottom of the cleaning cabinet is provided with a return water port connected to the water collecting tank. A turntable is rotatably installed in the cleaning cabinet.

A high-pressure air blow nozzle is installed on the high-pressure air pipe, a high-pressure nozzle is installed on the high-pressure water pipe, and a pressure-reducing spray box is installed on the low-pressure water pipe. Through the cooperation of the high-pressure air blow nozzle, the high-pressure nozzle and the pressure-reducing spray box, not only can the impurities on the die-casting be cleaned efficiently and thoroughly, but the turntable can also rotate back and forth at high speed to throw out the impurities through centrifugal force, further ensuring that the impurities are thoroughly cleaned.

[0037] like Figures 1 to 12 As shown, the present invention provides a spray cleaning system for an integrated die casting 5, comprising: a cleaning table 1, a loading mechanism 2 provided on the cleaning table 1, and a cleaning mechanism 3;

[0038] The feeding mechanism includes: a feeding frame 21 fixedly mounted on the cleaning table 1, a driving motor 22 fixedly mounted on the feeding frame 21, a sprocket 23 coaxially and fixedly connected to the output shaft of the driving motor 22, a chain 24 meshing with the sprocket 23, and a mounting plate 25 fixedly mounted on the chain 24;

[0039] During the cleaning process of the die-casting 5, the operator needs to fix the die-casting 5 on the mounting plate 25; it should be added here that the mounting plate 25 is pre-set with positioning mounting holes that match the structure of the die-casting 5; when the operator places the die-casting 5 stably on the surface of the mounting plate 25, it is necessary to ensure that the reserved holes on the die-casting 5 are accurately aligned with the positioning mounting holes on the mounting plate 25, and then use high-strength bolts for reliable fastening connection, so as to ensure that the die-casting 5 can be firmly and accurately installed on the mounting plate 25 during the transportation process, effectively avoiding the influence of vibration or displacement on the subsequent cleaning operation.

[0040] After the die-casting 5 is fixed and installed, the drive motor 22 is started; the drive motor 22 outputs power to drive the sprocket 23 to rotate; during the rotation process, the sprocket 23 drives the chain 24 to move linearly through the meshing action; the mounting plate 25 serves as a carrier for the die-casting 5, and moves synchronously with the chain 24 and the sprocket 23; in this way, under the drive of the continuous rotation of the drive motor 22, the die-casting 5 can gradually approach and smoothly pass through the cleaning mechanism 3 along the preset conveying path to complete the cleaning operation.

[0041] When the cleaning process of the die-casting 5 is completed, the drive motor 22 switches to the reverse rotation mode; at this time, the rotation direction of the sprocket 23 changes, thereby driving the chain 24 and the mounting plate 25 to move in the reverse direction; the die-casting 5 moves in the reverse direction synchronously with the mounting plate 25, and finally returns to the initial position. This design greatly facilitates the operator to perform the loading and unloading operations of the die-casting 5, and effectively improves the working efficiency.

[0042] The cleaning mechanism 3 includes: a cleaning frame 31 fixedly mounted on the cleaning table 1, a mounting ring 32 rotatably mounted on the cleaning frame 31, a nozzle 1 33 rotatably mounted on the mounting ring 32 via a male-female connector, and a swinging assembly 34 for driving the nozzle 1 33 to swing;

[0043] The nozzles 33 are arranged in multiple groups at equal intervals around the mounting ring 32.

[0044] After the die-casting 5 is fixed on the mounting plate 25, it gradually moves toward the cleaning rack 31 as the motor rotates; the die-casting 5 is driven by the chain 24 and passes through the inside of the cleaning rack 31; at this time, the nozzles 33 arranged along its periphery spray 360 degrees, greatly improving the cleaning effect; and preventing the problem of rotating cleaning due to the excessive size of the die-casting 5.

[0045] The swing assembly 34 includes: a drive ring 341 rotatably mounted on the cleaning frame 31, protrusions 342 equidistantly provided on the drive ring 341, and a drive assembly 343 for driving the drive ring 341 to rotate; one end of the nozzle 33 abuts against the surface of the drive ring 341;

[0046] The driving assembly 343 includes: a bevel gear 1 3431 coaxially fixedly connected to the sprocket 23, a bevel gear 2 3432 meshing with the bevel gear 1 3431, a driving wheel 3433 coaxially fixedly connected to the bevel gear, a plurality of latching protrusions 3434 spaced apart on the side wall of the driving wheel 3433, and a plurality of latching holes 3435 spaced apart on the driving ring 341, and the latching protrusions 3434 are used to be latched into the latching holes 3435.

[0047] When the motor drives sprocket 23 to rotate, sprocket 23 synchronously drives bevel gear 1 3431 to rotate. Because bevel gear 1 3431 and bevel gear 2 3432 mesh with each other, bevel gear 1 3431 drives bevel gear 2 3432 to transmit synchronously. As bevel gear 2 3432 rotates, it further drives the drive wheel 3433, which is coaxially fixed to it, to rotate. As the drive wheel 3433 rotates, the latching protrusions 3434 on its sidewalls continuously insert into the latching holes 3435 of the drive ring 341, thereby causing the drive ring 341 to rotate along the direction of the cleaning rack 31. Since one end of nozzle 1 33 abuts the drive ring 341, as the drive ring 341 rotates, nozzle 1 33 moves along with the undulating protrusions 342 on the drive ring 341, that is, rotates along the rotation point of its mounting ring 32. In this way, nozzle 1 33 can achieve circumferential swing while spraying inward, thereby greatly increasing the spraying area of ​​the nozzle.

[0048] The mother part of the mother-child connector is a multi-section undulating convex shaft 351, and the child part is a matching concave shaft 352; the convex shaft 351 is inserted into the concave shaft 352; the mother part and the child part are also elastically connected by a torsion spring 353; the mother part is fixedly connected to one end of the nozzle 33, and the child part is fixedly connected to one end of the mounting ring 32.

[0049] When the drive ring 341 rotates, the protrusion 342 on the drive ring 341 pushes one end of the nozzle 33 to deflect in the direction of the drive ring 341's rotation. This deflection causes the mother component, which is fixedly connected to the nozzle 33, to rotate on the daughter component. Because the mother component is provided with multiple undulating raised surfaces, the abutment of the raised surfaces causes the mother component to rotate on the daughter component, generating a downward undulating motion. Specifically, when the drive ring 341 rotates, the protrusion 342 causes the nozzle 33 to deflect in the direction of the drive ring 341's rotation. During this rotation, the mother component gradually pulls the nozzle 33 away from the drive ring 341, releasing the abutment between the protrusion 342 and the mother component. Subsequently, the elastic restoring force of the torsion spring causes the nozzle 33 to return to its original position, ready for the next abutment rotation.

[0050] The cleaning station 1 is also provided with a second nozzle 354 for cleaning the side end of the die casting 5;

[0051] When the motor drives the die-casting 5 to pass through the cleaning rack 31, it continues to move along the cleaning rack 31. At this time, the die-casting 5 on the cleaning rack 31 gradually approaches the second nozzle 354, and the second nozzle 354 flushes the side end of the die-casting 5, thereby cleaning the surface of the die-casting 5 more comprehensively.

[0052] Given that nozzles 1 (33) are arranged in a circular pattern and mounted at equal intervals on the mounting ring (32), in this layout, nozzles 1 (33) at the bottom are inevitably affected by dirt removed by nozzles 1 (33) above them when flushing the die-casting (5). These dirt adheres to the surface of nozzles 1 (33). Over time, the device continues to operate, and the cumulative effect of these dirt gradually becomes apparent, causing contamination on the surface of nozzles 1 (33), affecting their normal spraying performance. Therefore, after a certain period of use, nozzles 1 (33) must be cleaned to restore them to their proper working condition.

[0053] The inner arc surface of the driving ring 341 is provided with a guide groove 3411, and the outer arc surface of the mounting ring 32 is provided with a guide rod 321, and the guide rod 321 is inserted into the guide groove 3411;

[0054] As the motor drives the die-casting 5 toward nozzle 2 354, the drive ring 341 continues to rotate synchronously. At this time, the guide rod 321 on the mounting ring 32 moves from one end of the guide groove 3411 on the drive ring 341 to the other end. As the drive ring 341 continues to rotate in this direction, the guide rod 321 conducts the force and synchronously drives the mounting ring 32 to rotate. As the mounting ring 32 rotates, the nozzle mounted at the bottom of the mounting ring 32 switches with the nozzle at the top, eliminating the contamination risk nozzle at the bottom dead center position and achieving periodic positional exchange with the clean nozzle at the top dead center. This dynamic balancing mechanism effectively reduces the exposure time of a single nozzle to gravity and optimizes the contamination protection effectiveness of the nozzle assembly through a position cycle algorithm.

[0055] The cleaning station 1 is also provided with a switching component 4 for switching the cleaning liquid;

[0056] The switching assembly 4 includes: a raw liquid tank 41, a mixing tank 42, and a clean water tank 43 respectively fixedly mounted on the cleaning table 1; the clean water tank 43 is connected to the mixing tank 42; the raw liquid tank 41 is connected to the mixing tank 42; a cavity is provided in the mounting ring 32; a liquid inlet 44 is provided on the mounting ring 32, and a valve plate 45 is rotatably mounted on the outer side of the liquid inlet 44; a clean water port 46 and a mixed liquid port 47 are provided on the valve plate 45; the clean water port 46 is connected to the clean water tank 43; the mixed liquid port 47 is connected to the mixing tank 42; the nozzle 1 33 is connected to the mounting ring 32.

[0057] When the drive motor 22 drives the mounting ring 32 to rotate, the liquid inlet 44 provided on the mounting ring 32 switches the fluid path between the clean water tank 43 and the mixing box 42 by means of the linkage switching mechanism of the valve plate 45. Specifically, when the drive motor 22 drives the die casting 5 to perform a linear feed motion along the mounting rack toward the cleaning rack 31, the mounting ring 32 is fluidically connected with the mixing port 47 of the mixing box 42 through the liquid inlet 44 thereon. At this time, the cleaning liquid pre-proportioned in the mixing box 42 is ejected through the liquid inlet 44, the internal flow channel of the mounting ring 32 and the nozzle 33 under the action of the pumping pressure, thereby achieving efficient flushing of the oil stains on the surface of the die casting 5, significantly improving the efficiency of removing oily pollutants.

[0058] On the contrary, when the driving motor 22 drives the die casting 5 to move back in the opposite direction, the driving ring 341 drives the mounting ring 32 to rotate in the opposite direction through the synchronous transmission mechanism. At this time, the liquid inlet 44 on the mounting ring 32 establishes a fluid communication path with the clean water outlet 46 of the clean water tank 43. The nozzle 1 33 then switches the spray medium and sprays clean water in a targeted manner onto the surface of the die casting 5, performing a secondary flushing of the previously attached cleaning liquid and loosened oil stains. The shear force and impact force under the action of fluid mechanics further enhance the surface cleanliness of the die casting 5, achieving a deep cleaning effect.

[0059] It is worth mentioning that the clean water tank 43 and the raw liquid tank 41 are respectively equipped with independent pressurized pump devices, which form a closed loop with the inside of the tank through a pipeline system. Based on the feedback signal of the liquid level sensor, it can continuously and stably replenish fresh clean water to the clean water tank 43 and inject concentrated cleaning liquid into the raw liquid tank 41 to ensure the continuous supply of the medium and the concentration stability during the cleaning operation, thereby ensuring the reliable operation and efficient operation of the entire cleaning system.

[0060] Before the cleaning liquid is put into use, the traditional operating mode requires workers to manually measure and mix the cleaning liquid and clean water according to a specific dilution ratio. This process not only involves tedious ratio calculations, but also requires multiple pouring, stirring and other physical labor, which significantly increases labor costs and operational complexity, and reduces overall operational efficiency.

[0061] The mixing box 42 is further provided with a stirring shaft 48, which is coaxially fixedly connected to the sprocket 23; the stirring shaft 48 is provided with a stirring blade 49;

[0062] When the drive motor 22 starts and drives the sprocket 23 to rotate, the stirring shaft 48 rotates synchronously through the coaxial transmission mechanism, and the stirring blades 49 thereon form a strong vortex and shear force field in the mixing box 42, stirring and mixing the injected raw liquid and clean water in an all-round and deep manner, ensuring that the cleaning liquid reaches the ideal concentration uniformity and usage standards in a short time, effectively replacing the traditional manual stirring method.

[0063] It should be noted that the structural design of the mixing box 42 fully considers the principles of fluid dynamics and ease of operation. Its liquid inlet 44 and liquid outlet are located at both ends of the box, forming a clear fluid path. When the drive motor 22 drives the die-casting 5 to move toward the cleaning rack 31, the liquid outlet in the mixing box 42 is precisely connected to the fluid channel of the mounting ring 32, and the mixed cleaning liquid is smoothly ejected under the action of pressure, achieving precise cleaning of the die-casting 5; and when the die-casting 5 is driven away from the cleaning rack 31 by the motor, the liquid outlet automatically closes to prevent the cleaning liquid from leaking out. At the same time, the stirring shaft 48 keeps rotating under the continuous drive of the motor, continuously mixing and preparing the residual cleaning liquid or the newly injected liquid in the box, ensuring that the cleaning liquid is always in the best use state, providing strong support for subsequent cleaning operations.
