Description

Technical Field

[0001] This utility model relates to the field of shot blasting equipment technology, specifically a shot blasting device for surface reinforcement based on cast grinding disc tiles. Background Technology

[0002] In the production and processing of cast grinding discs, shot blasting is typically used to enhance surface properties such as surface hardness, wear resistance, and fatigue resistance. Shot blasting utilizes high-speed projectiles (such as steel shot or cast iron shot) to impact the workpiece surface, causing plastic deformation and forming a compressive stress layer with high hardness and good wear resistance. Simultaneously, it removes oxide scale, rust, and other impurities from the workpiece surface, improving its surface quality.

[0003] Traditional shot blasting equipment has several shortcomings when treating the surface of cast grinding discs. Firstly, due to the limitations of the internal structure, the movement of the cast grinding discs after entering the shot blasting equipment is not ideal, making it difficult to achieve sufficient tumbling and uniform blasting. This results in some surfaces not being effectively treated, affecting the consistency of the treatment effect. Secondly, during the shot blasting process, shot can easily remain on components such as the tumbling belt inside the equipment, which not only reduces the recycling efficiency of the shot and increases production costs but may also interfere with subsequent processing, affecting the processing quality. Furthermore, existing shot blasting equipment has poor adaptability to cast grinding discs of different specifications. When processing workpieces of different sizes and shapes, frequent adjustments to equipment parameters or replacement of parts are required, making operation cumbersome and inefficient.

[0004] To address the aforementioned issues, we propose a shot blasting device for surface reinforcement of cast grinding disc tiles. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a shot blasting device for surface enhancement of cast grinding disc tiles, including a machine body 1, a feed port 2, a discharge port, a shot blaster 3, a rolling belt 4, and an auxiliary actuation device 5.

[0017] The discharge port is not shown in the attached drawings. One end face of the machine body 1 is connected to the feed port 2, the other end face of the machine body 1 is connected to the discharge port, and the top surface of the machine body 1 is connected to the shot blaster 3.

[0018] The machine body 1 has an inner cavity, and the inner cavity is connected to the tumbling belt 4. The outer side of the machine body 1 is connected to a motor for driving the tumbling belt 4. In this embodiment, a three-phase asynchronous motor of model Y2-132M-4 is selected. The motor has moderate power and can stably drive the tumbling belt 4 to operate, meeting the processing requirements. The auxiliary actuation device 5 is rotatably connected to the inner cavity side wall of the machine body 1.

[0019] The workpiece to be processed enters through the feed port 2 and is guided into the inner cavity of the machine body 1 by the vibration motor 7 located below the feed port 2 and below the discharge port. In this embodiment, the vibration motor is model YZS-5-2, which has a moderate vibration frequency and amplitude.

[0020] When the external motor is turned on, it drives the tumbling belt 4 to work. The surface of the tumbling belt 4 is provided with protrusions. These protrusions cause the workpiece to tumble, ensuring that all surfaces of the workpiece are fully exposed to the shot thrown by the shot blaster 3, so as to achieve uniform blasting.

[0021] The auxiliary actuation device 5 includes a fixed rod 51, an actuation sleeve 52, a first connecting shaft 55, a sliding limit seat 53, and a sliding connecting rod 54.

[0022] One end of the first connecting shaft 55 is connected to another driving device. In this embodiment, a geared motor of model 5IK120RGN-CF is selected as the driving device, which can precisely control the rotation speed and direction of the first connecting shaft 55. The rotation direction of the first connecting shaft 55 must always be opposite to the direction of the rolling belt 4. The first connecting shaft 55 is rotatably connected to the inner cavity side wall of the machine body 1. The fixing rod 51 is sleeved on the outer circumference of the first connecting shaft 55, and the actuating sleeve 52 is sleeved on the outer side of the fixing rod 51. The actuating sleeve 52 is slidably connected to the outer side of the fixing rod 51. The sliding limit seat 53 is fixedly connected inside the fixing rod 51. One end of the sliding connecting rod 54 is slidably connected to the sliding limit seat 53, and the other end of the sliding connecting rod 54 is fixedly connected to the actuating sleeve 52. The actuating sleeve 52 assists in actuating the workpiece. The outer surface of the actuating sleeve 52 contacts the workpiece, and the elastic element prevents damage to the workpiece from hard contact. The elastic element also allows the auxiliary actuating device 5 to adapt to a wider range of workpiece sizes.

[0023] The sliding limit seat 53 has one end of an elastic element fixedly sleeved on its outer side, and the other end of the elastic element is fixedly connected to the actuating sleeve 52.

[0024] Furthermore, the two opposite outer sides of the fixed rod 51 are provided with sliding grooves, and the actuating sleeve 52 is provided with an elastic element mounting groove. The elastic element is disposed in the elastic element mounting groove of the actuating sleeve 52, and the actuating sleeve 52 is also provided with a sliding protrusion. The sliding protrusion of the actuating sleeve 52 is slidably connected to the sliding groove of the fixed rod 51.

[0025] The actuating sleeve 52 has a groove on the side that abuts against the workpiece, and multiple paddles are evenly arranged in the groove to further enhance the actuating effect.

[0026] An auxiliary pushing device 6 is rotatably connected to the inner cavity sidewall of the machine body 1. The auxiliary pushing device 6 includes pushing teeth 61 and a second connecting shaft 62. The pushing teeth 61 are sleeved on the outer circumference of the second connecting shaft 62. In this embodiment, the driving device connected to the second connecting shaft 62 is the same 5IK120RGN-CF geared motor as the first connecting shaft 55. The pushing teeth 61 not only assist in pushing the tumbling belt 4, but also create undulations in the tumbling belt 4, making it easier for residual shot to fall off, thereby further increasing the material circulation efficiency. Moreover, the pushing teeth 61 push the tumbling belt 4 to undulate, which can further improve the tumbling effect of the workpiece. The protrusions on the surface of the tumbling belt 4 also have a guiding effect, transporting the workpiece to the discharge port. The vibration motor 7 located below the discharge port vibrates, further transporting the workpiece out of the shot blasting device of this application.

[0027] Working principle: The workpiece to be processed enters from the feed port 2 and enters the inner cavity of the machine body 1 through the vibration motor 7.

[0028] When the external motor is turned on, it drives the tumbling belt 4 to work. The protrusions on the surface of the tumbling belt 4 cause the workpiece to tumble.

[0029] One end of the first connecting shaft 55 is connected to another driving device. The rotation direction of the first connecting shaft 55 must always be opposite to the direction of the rolling belt 4. The actuating sleeve 52 assists in actuating the workpiece. The outer surface of the actuating sleeve 52 contacts the workpiece, and the elastic element prevents hard contact from damaging the workpiece. The elastic element allows the auxiliary actuating device 5 to adapt to more specifications of workpieces.

[0030] The pushing teeth 61 in the auxiliary pushing device 6 can not only assist in pushing the tumbling belt 4, but also make the tumbling belt 4 undulate, making it easier for the residual shot on the tumbling belt 4 to fall off, thereby further increasing the material circulation efficiency.

[0031] Furthermore, the pushing teeth 61 push the tumbling belt 4 to rise and fall, which can further improve the tumbling effect of the workpiece to be processed.

[0032] The raised surface of the tumbling belt 4 also has a guiding effect, transporting the workpiece to be processed to the discharge port. The vibration motor 7 located below the discharge port vibrates, causing the workpiece to be processed to be further transported out of the shot blasting device of this application.
