Description

Technical Field

[0001] The invention relates to the technical field of sandblasting cleaning equipment, in particular to a high-frequency swinging sandblasting cleaning equipment for stainless steel castings. Background Art

[0002] In today's modern manufacturing system, stainless steel metal castings have always been highly concerned and valued by the industry due to their excellent physical properties, chemical properties and good mechanical properties, as well as their wide applicability in many key fields. However, with the widespread application of stainless steel castings in the industrial field, the requirements for the surface quality of castings are also increasing. During the production process of stainless steel castings, various impurities such as dirt, oxide layer, welding slag, etc. are often attached to their surfaces. These impurities not only affect the appearance quality of the castings, but may also have an adverse effect on the subsequent processing and performance of the castings. Therefore, it is particularly important to perform efficient surface cleaning treatment on stainless steel castings.

[0003] Traditional cleaning methods, such as manual scrubbing, mechanical cleaning and chemical cleaning, can achieve cleaning effects to a certain extent, but there are many problems. For example, manual scrubbing is inefficient and labor-intensive for operators; although mechanical cleaning is more efficient, there are often cleaning dead corners, affecting the cleaning effect; although chemical cleaning has a better cleaning effect, it may cause harm to the environment and human health.

[0004] In recent years, sandblasting cleaning technology has gradually been used in the field of stainless steel casting cleaning due to its advantages such as good cleaning effect, high efficiency and low environmental pollution. In the cleaning process of traditional sandblasting cleaning equipment, the operator often needs to hold the spray gun and manually control the movement of the spray gun to guide the nozzle to sandblast the surface of the stainless steel casting. However, in actual operation, due to the stubborn dirt and coating that may exist on the surface of stainless steel castings, the operator needs to have certain technical experience and operating skills to ensure the cleaning effect by repeatedly moving the spray gun. This manual operation method not only increases the labor intensity of the operator, but also due to the existence of human factors, the cleaning coverage area is limited, and cleaning dead corners are prone to occur, which in turn affects the cleaning effect and efficiency.

[0005] Specifically, when manually operating a spray gun for sandblasting cleaning, it is difficult for the operator to accurately control the movement trajectory and speed of the nozzle, which can easily lead to uneven sandblasting, excessive cleaning or insufficient cleaning. At the same time, manual operation also limits the continuity and stability of cleaning, and it is impossible to achieve continuous and efficient cleaning of the casting surface. In addition, due to fatigue and negligence of the operator, safety accidents may occur, causing damage to equipment and personnel. In response to the above problems, the present invention document proposes a high-frequency swing sandblasting cleaning device for stainless steel castings. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a high-frequency swinging sandblasting cleaning equipment for stainless steel castings, which can expand the cleaning coverage area of ​​the nozzle, realize all-round cleaning of the surface of the stainless steel castings, effectively avoid the occurrence of cleaning dead corners, and ensure the consistency and thoroughness of the cleaning effect. At the same time, due to the swinging motion of the nozzle, the surface of the stainless steel casting can be automatically cleaned back and forth without the operator having to hold the spray gun and move it repeatedly, thereby reducing the requirements for the operator's technical experience and operating skills and improving the applicability of the equipment.

[0012] Preferably, an exhaust pipe is installed on the side of the pressurized cabinet, and the other end of the exhaust pipe is connected to a nearby nozzle. A one-way valve is installed on the air inlet of the pressurized cabinet and the outer wall of the exhaust pipe.

[0013] Preferably, when the second rotating disk rotates, with the cooperation of the adjusting plate, the driving rod drives the movable plate to reciprocate up and down inside the pressurized cabinet, so that the outside air enters the pressurized cabinet, and after being compressed, it is discharged into the inside of the nozzle through the exhaust pipe, thereby achieving pressurization, thereby increasing the speed of abrasive spraying.

[0017] Compared with the prior art, the present invention provides a high-frequency swing sandblasting cleaning device for stainless steel castings, which has the following beneficial effects: 1. The high-frequency swinging sandblasting cleaning equipment for stainless steel castings is provided with a driving structure and a swinging structure. When the operator starts the equipment to clean the stainless steel castings, he only needs to turn on the driving motor, and the driving motor will drive the first rotating disk to rotate. Since the sliding rod is slidably connected to the inside of the first rotating disk, and the movable collar is cleverly sleeved on the outer wall of the connecting rod, this design enables the connecting rod to drive the two nozzles to swing through the two rotating bases. This swinging motion not only expands the cleaning coverage area of ​​the nozzle, but also realizes all-round cleaning of the surface of the stainless steel casting, effectively avoids the occurrence of cleaning dead corners, and ensures the consistency and thoroughness of the cleaning effect. At the same time, due to the swinging motion of the nozzle, the surface of the stainless steel casting can be automatically cleaned back and forth, without the operator having to hold the spray gun and move it repeatedly, thereby reducing the requirements for the operator's technical experience and operating skills, and improving the applicability of the equipment.

[0018] 2. The high-frequency swinging sandblasting cleaning equipment for stainless steel castings is provided with a pressing structure and a pressurizing structure. When the operator uses the equipment to clean the surface of the stainless steel casting, the driving motor drives the first rotating disk to rotate. With the cooperation of the linkage structure, the rotating shaft can drive the second rotating disk to rotate. The second rotating disk drives the movable plate to move up and down inside the pressurized cabinet through the adjusting plate and the driving rod. This movement process effectively introduces external air into the pressurized cabinet and transfers it to the nozzle after being compressed through the exhaust pipe, thereby realizing dynamic adjustment and enhancement of the air pressure during the sandblasting cleaning process, which not only improves the speed and impact force of the abrasive ejection, but also enhances the friction between the abrasive and the casting surface, thereby being able to more efficiently remove stubborn dirt and coatings on the surface and enhance the cleaning effect.

[0019] 3. The high-frequency swing sandblasting cleaning equipment for stainless steel castings, by setting up a linkage structure and cleverly using the transmission mechanism of the driving gear and the driven gear, realizes that the driving motor drives the nozzle to swing through the rotating base, thereby significantly expanding the cleaning range. At the same time, the linkage structure can also synchronously drive the pressurization structure to increase the speed of abrasive ejection inside the nozzle and enhance the cleaning effect. This linkage effect not only makes the cleaning process more efficient and professional, but also through the exquisite gear design, that is, the diameter of the driving gear is larger than the diameter of the driven gear, ensuring that the rotation speed of the rotating shaft is higher than the rotation speed of the first rotating disk, thereby making the swing speed of the nozzle and the moving speed of the movable plate both within a reasonable and optimized range. This design not only ensures the uniformity and thoroughness of the cleaning effect, but also improves the stability and durability of the equipment, making the equipment more adaptable to the cleaning needs of various complex stainless steel castings.

[0029] Working principle: When the operator uses the equipment to clean the surface of the stainless steel casting, the driving motor 402 is directly turned on. Since the slide bar 404 is slidably connected to the inside of the first rotating disk 403, the movable collar 405 can follow the swinging movement of the rotating base 502 and the connecting rod 503, and move closer to the first rotating disk 403 or away from the first rotating disk 403. When the driving motor 402 drives the first rotating disk 403 to rotate, the first rotating disk 403 drives the connecting rod 503 to swing through the slide bar 404 and the movable collar 405, and the connecting rod 503 is connected to the first rotating disk 403. The rod 503 drives the two nozzles 6 to swing through the two rotating bases 502. The abrasive supply system stably and continuously delivers the abrasive to the inside of the sandblasting gun body 3. The spray gun body 3 then delivers the abrasive to the inside of the nozzle 6. When the sandblasting machine body 1 is working, the compressed air and the abrasive are mixed in the sandblasting gun. When the compressed air passes through the sandblasting gun, it is mixed with the abrasive to form a high-speed abrasive flow. These abrasive flows are ejected through the nozzle 6 to impact and grind the surface of the workpiece at a high speed, so that the two nozzles 6 can automatically clean the surface of the stainless steel casting back and forth. When the driving motor 402 drives the first rotating disk 403 to rotate, the driving gear 901 drives the two driven gears 902 to rotate, so that the rotating shaft 702 can drive the second rotating disk 703 to rotate. The second rotating disk 703 drives the movable plate 802 to move up and down inside the pressurized cabinet 801 through the adjustment plate 704 and the driving rod 805. Under the action of the one-way valve 804, the outside air enters the pressurized cabinet 801 through the air inlet, and then the air is compressed through the exhaust pipe 803 and transported to the inside of the nozzle 6. By further increasing the air pressure, the speed of the abrasive spraying is increased, thereby increasing the impact force and friction of the abrasive.
