Description

Technical Field

[0001] This utility model relates to a shot peening machine, belonging to the field of spring manufacturing equipment. Background Technology

[0002] Shot peening machines utilize the impact of high-speed shot streams on metal surfaces to create a plastic cyclic strain layer, resulting in beneficial changes in the microstructure of this layer and introducing a residual compressive stress field into the surface layer, thereby improving the fatigue fracture and stress corrosion cracking resistance of metal parts.

[0003] For example, the existing application number 202320257679.7, entitled "An Adjustable CNC Shot Peening Machine," discloses a mechanism that uses two electric grippers to clamp metal parts during shot peening, ensuring stability and improving the overall stability of the process. When adjustment is needed, a flipping mechanism automatically flips and adjusts the shot-peening surface, making the process more convenient and intelligent. This effectively eliminates the need for manual flipping, reducing labor costs, increasing shot peening efficiency, and enhancing the convenience of the CNC shot peening machine. Furthermore, it allows for more precise spraying of the shot from the air nozzle onto the metal parts, effectively improving the shot peening effect and ensuring the quality of the finished metal parts.

[0004] However, in the above-mentioned equipment, the air blowing head is connected to the high-pressure air blowing pump and the shot storage tank respectively through air delivery and shot delivery. Due to the use of air delivery and shot delivery, the material is relatively soft, especially the foldable material. In addition, the air blowing head moves repeatedly. If the shot is wet or impurities stick to the inner wall of the shot delivery, the shot will not be able to fold. Or if the pipe is too soft, the shot will stack when it is close to the shot storage tank, which can easily cause the shot to accumulate, resulting in blockage and interruption of the supply.

[0005] Therefore, this utility model provides a shot peening machine with a shot conveying pipeline that is not easily blocked. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a shot peening machine with a shot conveying pipeline that is not easily blocked.

[0007] This utility model is implemented as follows:

[0008] A shot peening machine includes a shot conveying pipe, an air blowing head, a shot storage tank, a machine body, a receiving cavity, and a high-pressure air blowing pump. The machine body is provided with a receiving cavity for placing springs. A moving mechanism is provided on the inner wall of the machine body at the top of the receiving cavity. The air blowing head moves horizontally in the moving mechanism. The high-pressure air blowing pump and the shot storage tank are respectively installed at the top of the machine body.

[0009] The shot storage tank is connected to the side of the air blowing head through a shot delivery pipe, and the high-pressure air blowing pump is connected to the top of the air blowing head through a hose, so that the shot delivered from the side of the air blowing head is blown off the air blowing head by high wind.

[0010] The shot delivery pipeline includes a first pipeline, a second pipeline, and a third pipeline nested in sequence. The end of the first pipeline connected to the shot storage tank is an incomplete sphere with a hollow interior, and the end of the third pipeline connected to the air blowing head is an incomplete sphere with a hollow interior, so that the connection points of the first pipeline and the third pipeline with the shot storage tank and the air blowing head change direction as the air blowing head moves horizontally.

[0011] As a further improvement, the first, second, and third pipes are all variable diameter pipes, and the diameters of the first, second, and third pipes facing the head of the pellet storage tank are all smaller than those of the other end.

[0012] As a further improvement, the first, second, and third pipes are all curved pipes.

[0013] As a further improvement, the first, second, and third pipes are made of lightweight materials.

[0014] As a further improvement, the first, second, and third pipes are made of aluminum alloy or stainless steel.

[0015] As a further improvement, the shot delivery pipeline also includes several ball bearings, which are respectively installed at the connection between the first pipeline and the shot storage tank, and at the connection between the third pipeline and the air blowing head.

[0016] As a further improvement, this utility model includes a screen, a partition, a pellet recycling box, and a whole pellet recycling box. The bottom of the machine body is divided into two spaces by the partition. The screen is installed at an angle on the top of the partition and is located directly below the air blowing head. The pellet recycling box is located directly below the screen, and the whole pellet recycling box is located on the other side of the partition. The whole pellet recycling box and the pellet recycling box are on the same horizontal line. Both the pellet recycling box and the whole pellet recycling box are detachably connected to the bottom of the machine body.

[0017] As a further improvement, limiting rings are provided on the inner or outer walls of the ends of the first, second, and third pipes.

[0018] The beneficial effects of this utility model are as follows: Compared with the traditional shot delivery hose, this application uses a telescopic shot delivery pipe for connection, which expands and contracts synchronously with the movement of the air head. Moreover, the shot delivery pipe is a curved pipe made of a high-hardness material with a small curvature, which makes it less prone to clogging. The shot delivery pipe is made of a lightweight material, which reduces the load pressure on the horizontal movement of the air head and allows it to move more smoothly. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Reference Figures 1-4 As shown, this embodiment provides a specific implementation of a shot peening machine, including a shot conveying pipe 10, an air blowing head 20, a shot storage tank 30, a machine body 40, a receiving cavity 50, and a high-pressure air pump 60. The receiving cavity 50 for placing springs is provided inside the machine body 40. A moving mechanism is provided on the inner wall of the machine body 40 at the top of the receiving cavity 50. The air blowing head 20 moves horizontally in the moving mechanism. The high-pressure air pump 60 and the shot storage tank 30 are respectively installed at the top of the outside of the machine body 40.

[0028] The shot storage tank 30 is connected to the side of the air blowing head 20 through the shot conveying pipe 10, and the high-pressure air blowing pump 60 is connected to the top of the air blowing head 20 through the hose 12, so that the shot delivered from the side of the air blowing head 20 is blown off the air blowing head 20 by the high wind.

[0029] The shot delivery pipe 10 includes a first pipe 101, a second pipe 102, and a third pipe 103 nested in sequence. The end of the first pipe 101 connected to the shot storage tank 30 is an incomplete sphere with a hollow interior, and the end of the third pipe 103 connected to the air blowing head 20 is an incomplete sphere with a hollow interior, so that the connection parts of the first pipe 101 and the third pipe 103 to the shot storage tank 30 and the air blowing head 20 change direction as the air blowing head 20 moves horizontally.

[0030] This utility model includes a screen 70, a partition 80, a pellet recycling box 90, and a whole pellet recycling box 11. The bottom of the machine body 40 is divided into two spaces by the partition 80. The screen 70 is installed at an angle on the top of the partition 80 and is located directly below the air blowing head 20. The pellet recycling box 90 is located directly below the screen 70. The whole pellet recycling box 11 is located on the other side of the partition 80, and the whole pellet recycling box 11 and the pellet recycling box 90 are on the same horizontal line. Both the pellet recycling box 90 and the whole pellet recycling box 11 are detachably connected to the bottom of the machine body 40.

[0031] In the above technical solution, compared with the traditional shot delivery hose 12, this application uses a telescopic shot delivery pipe 10 for connection. It extends and retracts synchronously with the movement of the air inflator. The shot delivery pipe 10 is a curved pipe made of a high-hardness material with a small curvature, which makes it less prone to clogging. As the shot delivery pipe 10 transports the shot in the shot storage tank 30 to the air blowing head 20, the gas in the high-pressure air pump 60 is also injected into the air blowing head 20 through the hose 12. The high-pressure air is used to transport the shot to the receiving cavity 50 to process the spring to be processed. The incomplete shot after processing falls into the fragmented shot recovery box 90 through the screen, and the complete shot falls into the whole shot recovery box 11 along the screen. Both the whole shot recovery box 11 and the fragmented shot recovery box 90 can be removed from the machine body 40 for easy cleaning of the shot in the whole shot recovery box 11 and the fragmented shot recovery box 90.

[0032] The spring to be processed can move in and out because a door is rotatably connected to the machine body 40. The door can be opened and closed to insert or remove the spring.

[0033] In this embodiment, to facilitate the extension and retraction of the shot delivery pipeline 10, the first pipeline 101, the second pipeline 102, and the third pipeline 103 are all variable diameter pipelines, and the diameter of the first pipeline 101, the second pipeline 102, and the third pipeline 103 facing the shot storage tank 30 is smaller than that of the other end. That is to say, during the extension and retraction process, because the constituent pipelines of the shot delivery pipeline 10 are all variable diameter pipelines, when the length is shortened, the first pipeline 101 can be concealed in the second pipeline 102, and the second pipeline 102 can be concealed in the third pipeline 103, so that the problem of being unable to extend and retract will not occur, thereby achieving the purpose of extending and retracting the shot delivery pipeline 10.

[0034] Furthermore, the inner or outer walls of the ends of the first pipe 101, the second pipe 102, and the third pipe 103 are provided with limiting rings 111 to restrict the movement range of the first pipe 101, the second pipe 102, and the third pipe 103 and determine the flow trajectory.

[0035] In this embodiment, the first pipe 101, the second pipe 102 and the third pipe 103 are all arc-shaped pipes, which are small curvature pipes with small bending angles and large radii, reducing right angles and corners and avoiding the problem of bullet blockage.

[0036] As one possible specific implementation of the shot delivery pipe 10, the first pipe 101, the second pipe 102 and the third pipe 103 are made of lightweight materials. The lightweight materials are a new type of inorganic composite material composed of alkali-resistant glass fiber as reinforcement, low-alkalinity sulfoaluminate cement as binder and appropriate aggregates. It is prepared by processes such as spraying, vertical mold casting, extrusion and slurry casting. It can replace traditional building materials to achieve structural weight reduction, reduce the load pressure of the horizontal movement of the air blowing head 20, and make it move more smoothly.

[0037] As one possible specific implementation of the shot delivery pipe 10, the first pipe 101, the second pipe 102 and the third pipe 103 are made of aluminum alloy or stainless steel. Aluminum alloy or stainless steel is lightweight, does not easily rust, meets the requirements of rigid materials, has low manufacturing cost, and can also reduce the load pressure of the horizontal movement of the air blowing head 20, allowing it to move more smoothly.

[0038] As one possible specific implementation of the shot conveying pipe 10, in order to make the shot conveying pipe 10 extend and retract more smoothly and rotate more objectively during horizontal movement, the shot conveying pipe 10 also includes ball bearings 104, in several quantities, which are respectively installed at the connection part between the first pipe 101 and the shot storage tank 30, and at the connection part between the third pipe 103 and the air blowing head 20.

[0039] As a possible specific embodiment of the shot delivery pipe 10, in order to prevent shot from accumulating at the connection position between the third pipe 103 and the air blowing head 20, when the shot delivery pipe 10 is in a fully extended state, the third pipe 103 includes a spherical end and an arc-shaped part. A second screen 131 is fixed between the bottom end of the spherical end of the third pipe 103 and the tangent point of the air blowing head 20 and the arc-shaped port of the third pipe 103 to prevent shot from depositing in that part.

[0040] To prevent incomplete projectiles from filling the space below the second screen 131, a filler can be used to fill the space between the second screen 131 and the inner wall of the spherical end. The filler includes, but is not limited to, silicone material, plastic material, etc., as long as it can fill the space and prevent the projectile from falling on the filler.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
