Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine lifting tools, and in particular to a special large workpiece lifting tool for shot blasting machines. Background Technology

[0002] A shot blasting machine is a surface treatment device that uses a high-speed rotating impeller to propel steel shot, steel grit, or other projectiles at extremely high speeds onto the surface of a workpiece. Its core principle is to utilize the impact kinetic energy of the projectiles to achieve various processing purposes on the workpiece surface, such as rust removal, oxide scale removal, deburring, strengthening, and surface cleaning. In industrial production, shot blasting machines are widely used. Whether it's cleaning the surface of castings and forgings in machinery manufacturing to remove impurities and improve subsequent processing accuracy; pre-treating car bodies and frames in the automotive industry to enhance coating adhesion and ensure vehicle appearance and service life; or performing surface strengthening treatment on metal components in large-scale engineering projects such as bridges and steel structures before corrosion protection to improve the fatigue strength of the components, shot blasting machines play an irreplaceable role. Currently, the lifting devices used in shot blasting machines for large workpieces are mostly made of 45# steel through welding. They need to be tempered to achieve a certain hardness, but even after tempering, it is only a thin surface layer, and the internal structure still does not meet the wear resistance requirements. Therefore, when the surface wear-resistant layer is worn away by steel shot for a long time, the internal wear rate will accelerate. To solve this problem, people can only increase the size of the material to extend the service life. However, increasing the size of the material will prevent the steel shot blasted by the shot blasting machine from effectively hitting the workpiece due to the obstruction of the lifting device, resulting in poor workpiece cleaning effect. At the same time, increasing the size of the material will also significantly increase the manufacturing cost.

[0003] When a shot blasting machine is in operation, a lifting device is needed to lift the parts for operation. Therefore, a special large workpiece lifting device for shot blasting machines is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a special large workpiece lifting tool for shot blasting machines to address the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model solves the problems of poor appearance quality and low efficiency of concrete surface forming caused by human carelessness and the need to lift slurry during the rolling process, which creates footprints and wave pits of different depths.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A special large workpiece spreader for shot blasting machines, comprising: connecting plates, two pin shafts are arranged on the inner sides of the two connecting plates, an upper hanging plate is movably connected to the surface of the pin shafts, an upper bending plate is welded to the bottom of the connecting plates, a rib plate is welded to the bottom of the upper bending plate, a lower inclined plate is welded to the bottom of the rib plate, and a hanging plate is welded to the bottom of the lower inclined plate.

[0007] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, a plurality of through openings are formed at the bottom of the hanging plate, and the through openings are uniformly distributed in a straight line.

[0008] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, the two pin shafts are welded to the inner sides of the two connecting plates.

[0009] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, the upper bending plate is herringbone-shaped, and the middle of the inner bending side is connected to the hanging plate.

[0010] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, the lower inclined plates are respectively welded on both sides of the middle position of the hanging plate, and rib plates are uniformly distributed between the upper bending plate and the lower inclined plates to weld and connect the upper bending plate, the lower inclined plates and the hanging plate.

[0011] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, both the upper bending plate and the lower inclined plates are inclined at 30 degrees, and the upper bending plate and the lower inclined plates are used in cooperation with steel shots.

[0012] As a preferred embodiment of the special large workpiece spreader for shot blasting machines provided by the utility model, the connecting plates, the pin shafts, the upper hanging plate, the upper bending plate, the rib plates, the lower inclined plates and the hanging plate are all made of wear-resistant steel plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: 1. The special large workpiece spreader for shot blasting machines provided by the utility model is manufactured by adopting wear-resistant steel plate (same material as the protective plate of the shot blasting machine), the internal and external strength of the material is the same, so the service life is long. The reason why wear-resistant steel plate is adopted instead of wear-resistant profiles is that it is convenient for blanking (plasma, flame or laser can be used for blanking), which avoids ugly appearance caused by difficulty in subsequent processing. The upper bending plate and the lower inclined plates are welded with the hanging plate to form a triangle, which adopts the triangle stability principle and has small deformation, and the inclined structures of the bending plate and the lower inclined plates can prevent steel shots from accumulating on them and being taken out of the shot blasting chamber.

[0020] Preferably, all parts of the spreader are made of wear-resistant steel plate, and the 30-degree inclination design of the upper bending plate 4 and the lower inclined plate 6 can achieve good cooperation with steel shots. During shot blasting operation, the direct impact of steel shots on the spreader itself can be reduced, the wear rate is lowered, the service life of the spreader is prolonged, and meanwhile, the structural stability is ensured in long-term operation, and deformation or damage due to material problems is not easy to occur.

[0021] Preferably, the upper bending plate 4 is in a herringbone shape, the middle of the inner bending side is connected with the hanging plate 7, and in combination with the uniform distribution of the rib plates 5 between the two, the upper bending plate 4, the lower inclined plate 6 and the hanging plate 7 are welded stably.

[0022] Preferably, two pin shafts 2 are welded on the inner side of the connecting plate 1, providing a stable movable connection point for the upper hanging plate 3, which is convenient for the spreader to flexibly cooperate with lifting equipment; a plurality of through openings at the bottom of the hanging plate 7 are uniformly distributed in a straight line, and a suitable connection position can be selected according to the structural characteristics of the large workpiece, which enhances the adaptability during hoisting, ensures the stable position of the workpiece during shot blasting, and facilitates the uniform action of steel shots on the surface of the workpiece.

In this process, steel shots can smoothly act on the surface of the workpiece to complete the treatment, and all components of the spreader cooperate to realize the dual functions of stable hoisting of large workpieces and adaptation to shot blasting operation.
