Description

Technical Field

[0001] This utility model relates to the field of material surface strengthening technology, specifically to a material surface strengthening abrasive water jet device with adjustable abrasive particle size. Background Technology

[0002] Waterjet technology, as a novel materials processing technology, is widely used in various fields such as mining, military activities, and machinery manufacturing due to its characteristics of low mechanical vibration, dust-free operation, and low cutting heat. In surface shot peening, waterjet technology possesses unique advantages. Traditional shot peening techniques, using solid projectiles, tend to create significant surface roughness on parts. Once the projectile breaks and embeds into the surface, it further degrades surface properties. In contrast, waterjet, as a flexible processing method, creates lower surface roughness during impact. This not only strengthens the grain and microstructure but also allows for micro-polishing of the surface through the radial jet generated after impact, comprehensively improving the overall surface performance of the parts.

[0003] Patent CN111270059A discloses a multi-beam pulse water jet shot peening device for surface strengthening of large-size plates. The invention includes a feeding mechanism, a high-pressure water supply system, a multi-beam pulse jet generator, a fixed platform, and a base. The fixed platform and feeding mechanism are mounted on the base. The multi-beam pulse jet generator includes a high-pressure jet box and multi-beam nozzles. The high-pressure jet box is mounted on the feeding mechanism and suspended above the fixed platform. Multi-beam nozzles are located at the bottom of the high-pressure jet box. The high-pressure jet box is connected to the high-pressure water supply system via a pipe. This invention features high single-point shot peening coverage, controllable shot peening intensity, and no need to add abrasive particles, making it suitable for surface shot peening strengthening of large-size plates.

[0004] While the aforementioned inventions can control the shot peening area through a three-axis gantry structure, resulting in high shot peening coverage and controllable intensity, they do not allow for convenient replacement of the type of abrasive used in shot peening. Therefore, we propose a waterjet device for surface strengthening of materials with adjustable abrasive particle size. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A water jet device for surface strengthening of materials with adjustable abrasive particle size includes a shot peening device body, wherein a material storage mechanism is provided on the upper side of the shot peening device body. The storage mechanism includes two symmetrically placed vertical support plates, a horizontal support plate welded to the top of the vertical support plates, and three storage boxes fixedly installed on the upper surface of the horizontal support plates. A discharge channel is installed on one side of the lower surface of each storage box, and a screw feed rod is provided inside the discharge channel. A motor support plate is rotatably connected to the top of the screw feed rod. A motor for controlling the rotation of the screw feed rod is installed on the upper surface of the motor support plate, and one side of the motor support plate is welded to the inner wall of the storage box.

[0009] As a preferred technical solution, the length of the spiral feed rod is greater than the depth of the discharge channel, and the spiral feed rod is in close contact with the inner wall of the discharge channel.

[0010] These three features include: through holes to facilitate the entry of abrasive from the storage bin into the discharge channel; and guide blocks to guide the abrasive, allowing it to enter the discharge channel more smoothly and reducing abrasive residue in the storage bin.

[0013] As a preferred technical solution, the feeding mechanism includes an inlet pipe, a mixing pipe fixedly installed at the upper end of the inlet pipe, and a diversion pipe installed at the top of the mixing pipe, wherein a high-pressure water pipe is fixedly connected to the side surface of the mixing pipe.

[0014] This setup allows the high-pressure water pipe to introduce high-pressure water into the mixing pipe, and the branch pipe to guide abrasives from different storage tanks into the mixing pipe. The abrasives and high-pressure water are then mixed in the mixing pipe, providing a suitable abrasive water jet for subsequent material surface strengthening.

[0015] As a preferred technical solution, the diversion pipe is divided into three pipes, each of which is equipped with a valve on its outer side, and each of the diversion pipes is connected to each discharge channel by an elastic telescopic pipe.

[0016] In this setup, the three diversion pipes correspond to the discharge channels of the three storage tanks respectively. The opening and closing of different diversion pipes can be controlled by valves, enabling the selection and use of abrasives with different particle sizes.

[0017] As a preferred technical solution, the elastic telescopic tube and the diversion tube are fixedly connected by a flange, and the discharge channel and the elastic telescopic tube are fixedly connected by a thread.

[0018] This design, with its flange connection, features a strong connection and good sealing performance, ensuring a stable connection between the elastic expansion tube and the distribution tube, as well as a tight seal for fluid transport.

The storage mechanism 200 includes two symmetrically placed vertical support plates 210, a horizontal support plate 220 welded to the top of the vertical support plate 210, and three storage boxes 230 fixedly installed on the upper surface of the horizontal support plate 220. A discharge channel 231 is installed on one side of the lower surface of the storage box 230. A spiral feeding rod 232 is provided inside the discharge channel 231. A motor support plate 233 is rotatably connected to the top of the spiral feeding rod 232. A motor 234 for controlling the rotation of the spiral feeding rod 232 is installed on the upper surface of the motor support plate 233. One side surface of the motor support plate 233 is welded to the inner wall of the storage box 230. Through the above mechanism, multiple storage mechanisms 200, together with the feeding mechanism 170, can realize the selection and adjustment of the abrasive particle size as needed, which is convenient for flexible selection of particle size according to processing requirements.

[0024] Furthermore, such as Figure 5 As shown, a through hole is provided at the installation position of the discharge channel 231 on the lower surface of the storage box 230. Guide blocks are provided at the lower ends of the left and right side walls inside the storage box 230. The cross-section of the guide blocks is a right-angled trapezoid. The discharge channel 231 is located between the two guide blocks. The side surface of the guide blocks is smooth. The length of the spiral feed rod 232 is greater than the depth of the discharge channel 231. The spiral feed rod 232 is close to the inner wall of the discharge channel 231. The length of the spiral feed rod 232 is greater than the depth of the discharge channel 231, which can ensure that the abrasive in the discharge channel 231 is fully conveyed. The design of being close to the inner wall can reduce the residue of abrasive in the channel and ensure the thoroughness of feeding.

[0025] In this embodiment, as Figure 2As shown, the shot peening device body 100 includes a base 110, a placement box 120 installed at the middle position of the upper surface of the base 110, two support frames 130 installed on the front and rear sides of the upper surface of the base 110, a support beam 140 slidably connected between the two support frames 130, and a fixing mechanism 150 disposed on the outside of the support beam 140. A high-pressure jet box 160 is installed on the left side surface of the fixing mechanism 150, and a feeding mechanism 170 is fixedly installed at the middle position of the upper surface of the high-pressure jet box 160, which facilitates the adjustment of the position of the high-pressure jet box, thereby adapting to the surface strengthening treatment of materials of different sizes and improving the versatility of the device.

[0026] In this embodiment, as Figure 3 As shown, the feeding mechanism 170 includes an inlet pipe 171, a mixing pipe 172 fixedly installed at the upper end of the inlet pipe 171, and a diversion pipe 173 installed at the top of the mixing pipe 172. A high-pressure water pipe 175 is fixedly connected to the side surface of the mixing pipe 172. The diversion pipe 173 is divided into three pipes, and a valve 174 is provided on the outside of each diversion pipe 173. An elastic telescopic pipe is installed between each diversion pipe 173 and each discharge channel 231. The elastic telescopic pipe is fixedly connected to the diversion pipe 173 by a flange, and the discharge channel 231 is fixed to the elastic telescopic pipe by a thread. The high-pressure water pipe 175 introduces high-pressure water into the mixing pipe 172, and the diversion pipe 173 introduces abrasive from different storage tanks 230 into the mixing pipe 172. The abrasive and high-pressure water are mixed in the mixing pipe 172, providing a suitable abrasive water jet for subsequent material surface strengthening. The flange connection has the characteristics of strong connection and good sealing performance, ensuring a stable connection between the elastic expansion pipe and the diversion pipe 173 and the sealing of fluid transportation. The threaded connection facilitates the installation and disassembly between the elastic expansion pipe and the discharge channel 231, making it convenient for the maintenance and replacement of parts of the device.

[0027] It is worth noting that the structure and working principle of the motor 234 and valve 174 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here. The structure and working principle of the placement box 120, support frame 130, support beam 140, fixing mechanism 150 and high-pressure jet box 160 involved in this embodiment are all technologies disclosed in the prior art, and will not be described in detail here.

[0028] In this embodiment, the adjustable abrasive particle size material surface strengthening abrasive water jet device is used in the following way: First, abrasive particles of different sizes are injected into the three storage tanks 230 in the storage mechanism 200. Then, during processing, the appropriate abrasive particle size is selected according to the processing requirements. After selection, the valve 174 on the diversion pipe 173 on the lower side of the storage tank 230 corresponding to the abrasive is opened. Then, the motor 234 inside the storage tank 230 is controlled to start rotating in the forward direction, and the spiral feeding rod 232 is controlled to rotate in the forward direction. The abrasive in the storage tank 230 is sent out through the discharge channel 231, enters the diversion pipe 173 through the elastic telescopic tube, and finally mixes with water in the mixing pipe 172. After mixing, it enters the high-pressure jet box 160 and is finally sprayed out by the nozzle to polish the material surface.
