Description

1 TARIFF A MACHINE FOR SURFACE PREPARATION OF METAL SHAFTS TECHNICAL FIELD The invention relates to a laser sandblasting machine for surface preparation of metal shafts. 5 STATE OF THE ART Shaft blasting removes rust, burrs, and other imperfections from cylindrical metal shafts and rod materials. using high-speed abrasive particles to remove residues such as slag and old paint It is a specialized industrial surface preparation process that cleans the surface of metal shafts. to completely remove corrosion and dirt, roughening the material for new paint or to ensure perfect adhesion of the coating and to remove burrs and Sandblasting is performed to remove defects. Generally, the materials... The shaft is moved along conveyor systems (usually V-type) and special machines move it along the shaft. Sandblasting is a process that involves spraying abrasive sand or grit around a surface under high pressure. 15 This is done. In addition, knurling and chemical treatments are used for shaft surface preparation. Roughening techniques can also be used. Document number WO2025086147A1, “A method of producing a dandy roll and a The dandy roll manufacturing method involves processing a steel coil into a steel coil 20 to obtain the body (110) and multiple coating areas on the steel coil body to process; to machine steel coils by performing mechanical or laser processing on steel pipes obtain a mask with multiple holes larger in diameter than the diameter of its body to compress and position the mask and attach the steel roller body to the mask. to place, each hole corresponds to a lining area; and in the lining areas 25 Sandblasting and spraying on the mask to form coating blocks (120) to perform operations; by engraving watermark patterns onto the cladding blocks Obtaining a dandy roll. Production method: local fixed point via masking. It provides coating and produces the dandy roll by sandblasting and spraying. It simplifies the process.” 30 Document number CN118664090A states, "This invention relates to the production of aluminum alloys..." a laser sandblasting device for surface treatment and the sandblasting process of this device 2 It provides and belongs to the technical field of aluminum alloy processing and solving the problem of the difficulty of achieving adequate sandblasting in aluminum alloys The laser sandblasting device consists of a device body and a power box. It consists of; the outer wall of a screw shaft that moves back and forth, with a movable block. It is in a geared connection; the laser spray gun body is located under the movable block 5 It is firmly attached to the part; the upper part of the screw shaft that moves back and forth. A limiting bar is mounted on this part; limiting block, limiting It is mounted on the outer wall of the rod and a hose, laser spray gun. It is securely attached to one side of its body. To the laser spray gun. According to this, thanks to the regulated back-and-forth moving screw shaft, the user can control the laser 10 When performing sandblasting with the spray gun body, a drive It can start the motor; under the influence of the drive motor, a transmission shaft moves back and forth. The screw shaft rotates; under the influence of a limiting bar and a limiting block, During the rotation of the screw shaft moving back and forth, a movable block It can be moved periodically to the left and right, thus completing the sandblasting process. 15 This is accomplished; and the movable block periodically rotates the laser spray gun body. by moving the laser spray gun body to the left and right This is summarized as "it ensures complete spraying of the aluminum alloy." DEFINITION OF INVENTION 20 The present invention eliminates the aforementioned disadvantages and the related technical It relates to a machine developed to bring new advantages to the field. The primary purpose of this invention is to use a laser in the surface preparation of a shaft. The goal is to create a machine. Here, 25 are directed to the processing area on a conveyor. laser heads in the processing area located in the middle section of the shaft profile chassis Their positions are perpendicular to the shaft and in a suitable position with each other. Roughening is performed using positioned laser heads.
