Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting devices, in particular to a surface sandblasting device for pig iron castings. Background Art

[0002] Cast iron castings usually have high hardness, wear resistance and compressive strength. During the production process, cast iron castings need to be cleaned by sandblasting. Under the action of the small jet flow, a large number of tiny burrs and depressions will form on the surface of the cast iron castings, giving the surface of the cast iron castings a rough effect, thereby achieving the cleaning purpose.

[0003] The patent with publication number CN210280611U discloses a sandblasting device for metal casting mold production, which includes a frame mechanism, a feeding mechanism and a sandblasting mechanism, and can manually adjust the sandblasting angle and the sandblasting speed.

[0004] However, the above patents still have the following problems in actual operation:

[0005] During the sandblasting process, cast iron castings are easily moved by the impact of high-speed sand flow, resulting in poor sandblasting effect. The lack of certain structures and manual control often lead to poor stability. At the same time, after some stable structures are fixed, they need to be released for angle adjustment, which is troublesome to operate. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the technical problem that during the sandblasting process, the pig iron castings are easily moved by the impact of high-speed sand flow, resulting in poor sandblasting effect, lack of certain structures and only relying on manual control, often with poor stability, and some stable structures need to be released after being fixed in order to adjust the angle, which is troublesome to operate, please refer to Figure 1-5 , this utility provides the following technical solutions:

[0023] A surface sandblasting device for pig iron castings comprises a box body 2, a sandblasting mechanism 1 is arranged on the top of the box body 2, a visual window 3 is arranged on the front of the box body 2, the visual window 3 allows an operator to visually observe the situation inside an operating chamber 21, and is convenient for observation and operation, an operating hole 4 is arranged below the visual window 3, an operating chamber 21 is opened inside the box body 2, and the operating hole 4 is connected to the operating chamber 21, a sliding component 5 is arranged on the side of the box body 2, a sand collecting trough 6 is arranged at the bottom of the box body 2, and support legs 7 are arranged on the periphery of the sand collecting trough 6.

[0024] In this embodiment, the sliding assembly 5 includes a baffle 51 and a drawer 52. The drawer 52 is fixedly connected to the inner middle of the baffle 51. The side of the box body 2 is provided with an opening corresponding to the size of the baffle 51. The inside of the opening is provided with a slide groove 22. The drawer 52 is slidably arranged inside the slide groove 22. The outside of the baffle 51 is provided with a pull handle 53. Through the pull handle 53, the operator can easily pull the drawer 52, making the loading and unloading of the pig iron casting more convenient. The middle part of the drawer 52 is rotatably provided with a positioning mechanism 8.

[0025] In this embodiment, the positioning mechanism 8 includes a turntable 81, a groove is provided at the edge of the turntable 81, the turntable 81 is rotatably arranged in the middle of the draw plate 52 through the groove, two parallel limit grooves 82 are provided on the top surface of the turntable 81, and two clamping teeth 83 are provided inside each limit groove 82, and an adjustment box 84 is provided in the middle of the bottom surface of the turntable 81. The positioning mechanism 8 can fix the pig iron casting during the sandblasting process to prevent it from moving during the sandblasting process, ensuring that the sandblasting process can be carried out in a stable state, thereby reducing repeated or unnecessary operations and improving work efficiency. During the sandblasting process, high-speed sand flow may cause impact on the pig iron casting. If the pig iron casting is properly fixed, its movement during the sandblasting process can be reduced, thereby reducing the risk of damage caused by impact. At the same time, because of the setting of the turntable 81, although the pig iron casting remains in a fixed state, it can also be rotated at a certain angle under human operation, and remains fixed during the rotation process, so that the flexibility during artificial sandblasting is higher.

[0026] In this embodiment, a knob 85 is provided at the middle of the bottom surface of the adjustment box 84, and the rotating shaft of the knob 85 extends vertically upward into the interior of the adjustment box 84. A bevel gear 87 is provided inside the adjustment box 84, and the rotating shaft of the knob 85 is fixedly connected to the rotating shaft of the bevel gear 87. Two screw rods 86 are symmetrically provided inside the adjustment box 84, and the threads of the two screw rods 86 are arranged in reverse. A bevel gear 88 is provided on one end of the two screw rods 86 close to the bevel gear 87, and the bevel gear 88 is meshed and connected with the bevel gear 87. A threaded sleeve 89 is connected to the screw rod 86 by threading, and a connecting shaft 810 is connected to the bottom of the clamping teeth 83. A guide groove is provided on the bottom surface of the adjustment box 84, and the connecting shaft 810 passes through the guide groove and is fixedly connected to the threaded sleeve 89. The design of the adjustment box 84 and the knob 85 allows the operator to easily adjust the positions of the two clamping teeth 83.

[0027] The working principle of the above content is: pull the handle 53 to slide out the drawer plate 52, place the pig iron casting that needs to be sandblasted in the middle of the turntable 81, adjust the placement position, and rotate the knob 85. The knob 85 drives the two bevel gears 88 to rotate through the bevel gear 87, thereby driving the two screw rods 86 to rotate. When the screw rod 86 rotates, it drives the threaded sleeve 89 to move toward or reversely inside the guide groove, thereby driving the clamping teeth 83 to move to clamp the pig iron casting. After clamping is completed, push the drawer plate 52 back to the inside of the operating chamber 21, and sandblasting can be performed through the sandblasting mechanism 1. During sandblasting, the turntable 81 can be rotated to adjust the angle of the fixed pig iron casting.
