Description

Technical Field

[0001] This utility model belongs to the field of shot blasting equipment technology, and in particular relates to a shot blasting equipment for the production and processing of aluminum alloy castings. Background Technology

[0002] In modern manufacturing, aluminum alloys are widely used in aerospace, automobile manufacturing, and machinery equipment due to their excellent properties such as low density, high strength, and corrosion resistance. The quality of aluminum alloy castings directly affects the performance and reliability of end products. Shot blasting, as a key process in the production and processing of aluminum alloy castings, uses high-speed shot to impact the surface of the castings. This not only effectively removes impurities such as oxide scale and adhering sand from the surface of the castings, but also generates residual compressive stress on the surface of the castings, significantly improving their fatigue strength and resistance to stress corrosion.

[0003] However, existing shot blasting equipment is not convenient for filtering the shot during use, which causes impurities to impact the casting surface at high speed again with the usable shot. This also increases the friction between the impurities and the usable shot, reduces the service life of the shot, and increases production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a shot blasting device for the production and processing of aluminum alloy castings. By setting up a filter section, it solves the problem that existing shot blasting devices are not easy to filter the shot during use, which causes impurities to hit the surface of the casting again at high speed with the usable shot. At the same time, it increases the friction between impurities and usable shot, reduces the service life of shot, and increases production costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a shot blasting device for the production and processing of aluminum alloy castings, including a processing box, and further including: a shot blasting section, which is installed on the processing box; a filtering section, which is disposed below the processing box; and a collecting section, which is disposed on the right side of the processing box; wherein, the collecting section is located to the right of the filtering section.

[0008] Furthermore, the filtration unit includes a filter assembly disposed below the processing chamber; and a shaking assembly located below the processing chamber; wherein the shaking assembly is located below the filter assembly.

[0009] Furthermore, the collection unit includes a guide assembly disposed on the right side of the processing box; and a collection assembly located on the right side of one of the four support legs; wherein the guide assembly is located above the shaking assembly, and the collection assembly is located on the right side of the filtering assembly.

[0010] Furthermore, the filter assembly includes an inclined trough disposed at the bottom of the processing chamber, with a protrusion fixedly connected to the bottom of the inclined trough and several elastic elements disposed at the bottom of the inclined trough; wherein, the top of the inclined trough contacts the processing chamber, the protrusion is triangular, and four elastic elements are disposed, each elastic element including a fixing block fixedly connected to the bottom of the inclined trough, a spring fixedly connected to the bottom of the fixing block, and a second support leg fixedly connected to the bottom of the spring; wherein, the two second support legs located on the right side are both shorter than the two second support legs located on the left side, and the filter assembly is used to filter the thrown projectiles and impurities.

[0011] Furthermore, the shaking assembly includes a motor fixedly connected to the rear side of the protrusion, the output shaft of the motor being fixedly connected to a rotating shaft via a coupling, and an eccentric wheel being fixedly connected to the front side of the rotating shaft; wherein, the rotating shaft passes through the protrusion, and the outer wall of the rotating shaft is rotatably connected to the protrusion, and the shaking assembly causes the inclined groove to shake under the action of the elastic element, preventing impurities from clogging the filter holes during filtration.

[0012] Furthermore, the guiding assembly includes a guide plate one fixedly connected to the top of the inclined chute, and a guide plate two fixedly connected to the inner wall of the inclined chute; wherein, the guide plate one and the slide rail are arranged crosswise, and the guide plate one is located above the guide plate two. The guiding assembly is used to guide the impurities and usable projectiles when they fall.

[0013] Furthermore, the collection assembly includes a waste box disposed on the right side of the inclined chute. Two slide rails are fixedly connected to the right side of the inclined chute, and sliders are slidably connected to the inner walls of the two slide rails. A shot box is disposed on the right side of the two sliders, and the outer walls of the two sliders are fixedly connected to the shot box. The top of the shot box is in contact with the inclined chute. The waste box is installed on the ground, and the top of the waste box is in contact with the inclined chute. The two slide rails are respectively adapted to the two sliders, and the tops of the two sliders are convex. The collection assembly is used to collect the filtered usable shot and impurities.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a filtration section, when it is necessary to filter the usable shot, the operator can first place the aluminum alloy casting on the placement plate, then close the processing box, start the motor, and the motor drives the eccentric wheel to rotate under the action of the rotating shaft. At the same time, under the elastic action of the spring, the inclined chute shakes. At this time, the shot blaster is started, and the shot blaster begins to process the aluminum alloy casting. As the shot blaster operates, the shot thrown out and the impurities on the aluminum alloy casting will fall down through several troughs on the placement plate. When the shot and impurities fall onto the inclined chute, the inclined chute filters the shot and impurities. The impurities will fall into the inside of the inclined chute, while the usable shot will remain at the top of the inclined chute. As the inclined chute shakes, the shot and impurities will slide down, thereby filtering the thrown shot, separating the impurities from the usable shot, preventing the impurities from hitting the casting surface at high speed again with the usable shot, reducing the friction between the impurities and the usable shot, improving the service life of the shot, and reducing production costs.

[0016] 2. By setting up a collection section, when it is necessary to collect the filtered shot, the waste box is placed on the right side of the inclined chute and fixed to the ground. Then, the two sliders on the left side of the shot box are installed downwards, aligned with the two slide rails respectively. When the protrusions on the top of the two sliders contact the two slide rails respectively, the two slide rails limit the two sliders, and the shot and impurities will slide down. When the usable shot at the top contacts the first guide plate, it slides to the left and falls into the shot box under the guidance of the first guide plate. When the impurities inside the inclined chute contact the second guide plate, they fall into the waste box under the guidance of the second guide plate, thereby recycling the usable shot and reducing consumable costs. At the same time, the shot box can be quickly inserted and removed through the slide rails and sliders, reducing working time and improving work efficiency.
