Description

Technical Field

[0001] The utility model belongs to the technical field of H-shaped steel shot blasting cleaning, in particular to an H-shaped steel shot blasting cleaning machine. Background Art

[0002] H-shaped steel is an economical and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". When cleaning its surface, a shot blasting machine is needed. The shot blasting machine uses a high-speed rotating impeller to throw projectiles onto the workpiece that is continuously turned over in the drum, so as to achieve the purpose of cleaning the workpiece. When working, the abrasive enters the center of the blasting head through the feed inlet. In the center of the blasting head, there is a shot-splitting wheel that rotates with the blasting head. The outside of the shot-splitting wheel is a directional sleeve. The shot-splitting wheel sends the abrasive through the opening on the directional sleeve to the end of the blade close to the center of the blasting head. Due to the action of centrifugal force, the abrasive particles are accelerated along the length of the blade until they reach the top of the blade and hit the workpiece surface at a very high speed. It is suitable for sand removal, rust removal, descaling and surface strengthening of castings and forgings weighing less than 15 kg in various industries.

The dust curtain 102 is made of silicone, and the connecting pipe 104 is made of PVC. The conveying component 2 makes the H-shaped steel lift the dust curtain 102 and convey it into the shot blasting box 101 for shot blasting cleaning. During the cleaning process, the dust in the shot blasting box 101 is sucked into the dust collecting box 107 by the dust suction hopper 103, the connecting pipe 104 and the dust suction pipe 105 and blocked by the breathable net 108.

[0026] In this embodiment: the conveying assembly 2 includes a conveying frame 201, five conveying rollers 202 are evenly arranged on the top of the conveying frame 201, and a driving box 203 is installed behind the five conveying rollers 202.

The limiting wheels 305 limit the H-shaped steel by its own weight during movement. Then the motor 302 drives the limiting shaft to rotate through the transmission key 303 to drive the limiting wheel 305 on the sliding sleeve 304 to rotate. At the same time, the limiting roller 301 drives the conveying roller 202 to rotate through the driving box 203, so that the H-shaped steel lifts the dust curtain 102 and transports it into the shot blasting box 101 for shot blasting cleaning; during the cleaning process, the dust suction pump 106 will push the shot blasting box The dust in 101 is sucked into the dust box 107 through the dust hopper 103, the connecting pipe 104 and the dust pipe 105 and is blocked by the air permeable net 108; when the size of the H-shaped steel changes, first loosen the fixing bolt 307 to allow the sliding sleeve 304 to drive the limiting wheel 305 to slide along the limiting roller 301, and adjust the spacing of the group of limiting wheels 305 to be consistent with the width of the H-shaped steel, and then tighten the fixing bolt 307 to fix the position of the sliding sleeve 304 through the fixed edge 306 to meet the limiting requirements of different sizes. At the same time, the multiple groups of limiting wheels 305 provided in the device can clean multiple H-shaped steels at the same time.
