Description

Technical Field

[0001] This application relates to the field of shot blasting technology, specifically to a shot blasting machine for aluminum alloy products. Background Technology

[0002] Aluminum alloy shot blasting machines use shot blasters to propel metallic or non-metallic shot (such as steel shot or aluminum shot) onto the surface of aluminum alloy at speeds exceeding 100 meters per second. The impact force of the shot removes impurities such as oxide scale, rust, and burrs, while simultaneously forming a dense compressive stress layer on the surface, thus improving hardness and fatigue resistance.

[0003] For example, patent CN215433252U discloses an aluminum alloy bracket shot blasting machine. This patent uses a water tank, sleeve, rotating rod, and spiral blade. After the drive motor is turned on, the rotating rod drives the spiral blade to rotate, so that the wet dust in the water tank is carried by the spiral blade to the outlet at the higher end of the sleeve. The wet dust falls into the receiving box after falling, so the operator only needs to replace the receiving box in time. There is no need to separate the powder and water in the water tank and then clean it, nor is it necessary to stop the machine when cleaning the water tank. This not only makes it convenient for the operator to operate, but also ensures the shot blasting efficiency.

[0004] In actual use, used steel balls are usually recycled and then reused through lifting devices or circulation mechanisms. However, when steel balls impact the surface of aluminum alloy products at high speed in shot blasting machines, long-term repeated impacts can cause micro-cracks inside the steel balls, eventually leading to fatigue fracture. If the broken fragments are recycled, the uneven impact force of the fragments may result in uneven surface treatment of the workpiece, with spots or scratches appearing.

[0005] Therefore, it is necessary to provide a shot blasting machine for aluminum alloy products to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-3 As shown, this application provides an aluminum alloy shot blasting machine, including a housing 1 fixedly installed inside the factory, and a shot blasting chamber 5 provided inside the housing 1, which is used to accommodate aluminum alloy products to be shot blasted.

[0038] Meanwhile, a shot blasting mechanism 2 is provided on the housing 1. In this application, the shot blasting mechanism 2 is a high-efficiency hook-type shot blasting machine with publication number CN211439579U. The shot blasting mechanism 2 has a shot blaster 24, and the shot blaster 24 is provided on one side of the housing 1. At the same time, the output end of the shot blaster 24 is connected to the shot blasting chamber 5 so that the shot blaster 24 can be used to spray shot onto the surface of aluminum alloy products.

[0039] In order to recycle the steel shot, a recycling mechanism 3 is provided on one side of the casing 1. The recycling mechanism 3 is used to recycle the used steel shot.

[0040] The circulation mechanism 3 includes a circulation channel 33 fixedly installed on one side of the cover 1. The bottom end of the circulation channel 33 is provided with an inlet 30, which is connected to the bottom end of the shot blasting chamber 5. After shot blasting is completed, the steel shot falls freely to the bottom end of the shot blasting chamber 5.

[0041] Furthermore, the bottom of the shot blasting chamber 5 is provided with a guide channel (not shown in the figure). This guide channel is inclined to the guide inlet 30 inside the shot blasting chamber 5, so that when the steel shot falls freely into the shot blasting chamber 5, it can be moved by the guide channel to the inlet 30 and then introduced into the circulation channel 33.

[0042] In order to guide the steel shot to the shot blaster 24, a motor 39 is fixedly installed on one side of the circulation channel 33, and the output end of the motor 39 passes through the circulation channel 33 and is fixedly connected to the first sprocket 31, so that starting the motor 39 can drive the first sprocket 31 to rotate inside the circulation channel 33.

[0043] Meanwhile, a second sprocket 34 is rotatably arranged at the upper end inside the circulation channel 33, and a chain 32 is driven between the second sprocket 34 and the first sprocket 31, so that the starting motor 39 can drive the chain 32 to operate inside the circulation channel 33 through the first sprocket 31.

[0044] Furthermore, multiple sets of lifting scoops 35 are fixedly installed on the chain 32, so that starting the motor 39 can drive the lifting scoops 35 to move along the chain 32 inside the circulation channel 33. When it is necessary to circulate the steel shot, the chain 32 can be driven to rotate. At this time, the lifting scoops 35 will move to the inlet 30 at the bottom of the circulation channel 33 under the drive of the chain 32. The steel shot falling from the bottom of the shot blasting chamber 5 can be loaded by inertia. Then, as the chain 32 continues to rotate, the lifting scoops 35 will carry these steel shot upwards along the circulation channel 33.

[0045] Furthermore, a conveying channel 36 is provided on one side of the upper end of the circulation channel 33. The conveying channel 36 is connected to the circulation channel 33. Thus, when the lifting spoon 35 lifts the steel shot to the top of the circulation channel 33, the steel shot falls naturally into the conveying channel 36 connected to one side of the circulation channel 33 under the action of gravity. At the same time, the conveying channel 36 is fixedly connected to the input end of the shot blaster 24, so that the steel shot can be conveyed to the shot blaster 24 for reuse through the conveying channel 36.

[0046] To prevent broken steel shot fragments from entering the circulation mechanism 3, a screening mechanism 4 is provided at the bottom of the casing 1, such as... Figure 1 and Figures 3-4 As shown, the screening mechanism 4 is used to screen used steel shot, thereby preventing steel shot fragments from damaging aluminum alloy parts.

[0047] The screening mechanism 4 includes a base 40 fixedly installed on both sides of the bottom end inside the cover 1, and multiple sets of springs 42 fixedly installed on the upper end of the base 40. At the same time, a fixing frame 45 is fixedly installed on the other end of the multiple sets of springs 42. The fixing frame 45 is inclinedly installed inside the cover 1, and a screen 43 is fixedly installed on the top of the fixing frame 45. The screen 43 is used to allow steel shot fragments to pass through.

[0048] It should be noted that the screen 43 is inclined inside the housing 1 along with the fixing frame 45, and the lower end of the inclined screen 43 is located directly in front of the inlet 30 so that the steel shot that is intact on the surface of the screen 43 can be guided along the screen 43 through the inlet 30 to the circulation mechanism 3 for recycling.

[0049] Furthermore, a vibration motor 44 is fixedly installed on one side of the fixed frame 45. When the vibration motor 44 is started, it can drive the screen 43 to vibrate at the bottom inside the cover 1 through the fixed frame 45. When steel shot needs to be screened, the vibration motor 44 can be started to drive the screen 43 to vibrate through the fixed frame 45. During the vibration, fragments with a hole diameter smaller than the screen 43 fall freely to the bottom through the screen 43, while intact steel shot can be guided into the circulation mechanism 3 through the inlet 30 along the screen 43.

[0050] Meanwhile, a guide plate 48 is inclinedly arranged on the fixed frame 45 at the lower end of the screen 43. The guide plate 48 is used to receive steel shot fragments, and an outlet 47 is provided at the bottom of the cover 1. The guide plate 48 is inclined at 45 degrees, and the inclination direction is from the inside of the shot blasting chamber 5 towards the outlet 47, so that the steel shot fragments can be transported along the guide plate 48 to the outlet 47 for subsequent centralized processing.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
