Description

Technical Field

[0001] This utility model relates to the field of high alloy steel casting technology, specifically to a surface treatment device for processing high alloy steel castings. Background Technology

[0002] High-alloy steel castings are made by adding more than 10% alloying elements to steel, which fundamentally changes their structure and gives them special properties such as wear resistance, heat resistance, and corrosion resistance. They belong to special cast steels. Typical materials include high manganese steel ZGMn13, which is used to manufacture wear-resistant parts such as tank tracks and excavator buckets; stainless steel ZG1Cr18Ni9, which is used for corrosion-resistant valve and pump components; and heat-resistant steel, which is used for parts of high-temperature heating furnaces. By adjusting the types and contents of alloying elements, these castings can specifically meet the performance requirements under complex working conditions and are irreplaceable in the field of equipment manufacturing.

[0003] According to the patent publication CN212330729U published on the Chinese Patent Network, a sandblasting treatment device for the surface of stainless steel castings includes a treatment chamber, which is connected to an inlet pipe and a outlet pipe. A hinged sealing door is located at the front of the treatment chamber. An installation plate is placed inside the treatment chamber, with vertical plates symmetrically arranged on the installation plate. A limiting rod is installed between the vertical plates, and an L-shaped plate and a sliding plate are fixedly installed on the limiting rod. A frustum is rotatably mounted on one side of the L-shaped plate and the sliding plate, and a gear is rotatably mounted on one side of the L-shaped plate. The gear is fixedly connected to the frustum, and a rack is meshed on the lower side of the gear. The device is mounted on an L-shaped plate. It uses a frustum and a sliding plate to fix multiple parts at the same time. The device fixes cylindrical parts with different diameters and lengths. The drive motor drives the rack to move back and forth, thereby driving the parts to rotate automatically. This makes it convenient for the sandblasting gun to sandblast the surface of the parts from all directions. However, the sandblasting machine for castings has a poor cleaning effect. When sandblasting the surface of the casting, some abrasive particles will adhere to the inner wall of the sandblasting machine, which is difficult to recover and reuse. This not only requires the user to clean it regularly, but also increases the wear and tear of abrasive.

[0004] Therefore, the surface sandblasting equipment needs to be redesigned and modified to effectively prevent it from becoming difficult to clean. Utility Model Content

[0035] As a technical optimization of this utility model, by setting the knocking cleaning component 3, the sandblasting machine body 1 can be knocked cleaned, so that the abrasive is dislodged from the sandblasting machine body 1 due to vibration, thereby improving the cleaning effect of the cleaning and collection component 2.

[0036] refer to Figure 6 A spring 4 is fixedly connected to the inner side of the striking rod 305, and the inner side of the spring 4 is fixedly connected to the inner wall of the rotating sleeve 304.

[0037] As a technical optimization of this utility model, by setting the spring 4, the striking rod 305 can slide within the rotating sleeve 304, thereby improving the striking effect of the striking rod 305.

[0038] refer to Figure 6 A ring 5 is fixedly connected to the surface of the striking rod 305, and the ring 5 is slidably connected to the rotating sleeve 304.

[0039] As a technical optimization of this utility model, by setting the ring 5, the striking rod 305 can be limited, preventing the striking rod 305 from disengaging from the rotating sleeve 304, thereby improving the stability of the striking rod 305.

[0046] refer to Figure 2 A limiting plate 9 is fixedly connected to the right side of the inner wall of the sandblasting machine body 1, and the limiting plate 9 is located on the surface of the moving frame 208.

[0047] As a technical optimization of this utility model, by setting the limiting plate 9, the moving frame 208 can be limited, thereby improving the moving stability of the moving frame 208.

[0048] The working principle and operation process of this utility model are as follows: When it is necessary to clean the inner wall of the sandblasting machine body 1, the drive motor 201 is started. The output shaft of the motor 201 drives the pulley 203 to rotate synchronously, which in turn drives the pulley 204 to rotate through the transmission belt, thereby driving the screw 205 assembly to rotate. The screw 205 drives the moving block 207 to move axially through the threaded pair. The moving block 207 pulls the moving frame 208 and the built-in cleaning brush 209 to move synchronously. The cleaning brush 209 forms elastic contact with the inner wall of the sandblasting machine body 1, and the mechanical peeling of the abrasive bonding layer is achieved through reciprocating motion. The peeled abrasive particles fall into the bottom collection assembly under the action of gravity. During the rotation of the screw 205, its The helical gear 301 mounted at the end and the vertically meshing helical gear 302 form a bevel gear transmission pair, converting the rotational motion into a vertical axial torque output. This torque drives the rotating rod 303 to rotate, and the rotating sleeve 304 at the end of the rotating rod 303 drives multiple sets of striking rods 305 to oscillate in a circular motion. The striking rods 305 periodically strike the outer shell of the sandblasting machine 1, generating vibration. This vibration energy is transmitted to the inner wall adhesive layer through the shell structure, causing residual abrasive to detach. Combined with mechanical brushing, a dual cleaning effect is achieved. The detached abrasive particles are collected into the collection component. This device effectively solves the problem of difficult cleaning of accumulated material on the inner wall of traditional sandblasting machines through the synergistic effect of mechanical transmission and vibration excitation. It has technical advantages such as high cleaning efficiency, high abrasive recovery rate, and short equipment downtime.

[0049] In summary, this surface treatment equipment for high alloy steel castings utilizes a cleaning and collection component to remove abrasive particles from the inner wall of the sandblasting machine for reuse. During sandblasting of the casting surface, it prevents some abrasive particles from adhering to the inner wall of the sandblasting machine, allowing them to be recycled and reused. This significantly reduces the number of cleaning operations required by the user, reduces abrasive consumption, and solves the problem of difficult cleaning.
