Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical industry, specifically to a rust removal machine for the surface of metallurgical shear blades. Background Technology

[0002] Metallurgical shear blades are key tools used in the metallurgical industry for cutting metal materials. They are widely used in industries such as steel mills and metal processing plants. Due to long-term service in high-temperature, high-humidity, and corrosive media environments, an oxide and rust layer inevitably forms on the blade surface. The presence of the rust layer not only reduces the cutting performance and service life of the blade, but also causes problems such as equipment downtime and increased energy consumption. In actual use, a rust removal machine is required to remove rust from the blade surface.

[0003] Traditional shear blades have certain technological defects in metal rust removal operations: First, the blades lack an adaptive rotation mechanism, requiring manual rotation and adjustment of the cutting angle throughout the process. This not only increases the time required for a single operation by more than 40%, but also significantly increases the safety risk factor due to frequent human-machine interaction. Furthermore, during manual operation, the blade is prone to slippage and loss of control due to shearing reaction force. Especially when dealing with high-hardness rust layers, the flying oxide debris and unpredictable movement trajectory of the blade can cause mechanical injuries and deep scratches to the operator. Second, after the rust removal process is completed, the surface of the shear blade will continue to be covered with iron filings and grinding dust due to the lack of an active cleaning device. These residues not only damage the surface finish of the workpiece and affect the adhesion of coatings and other subsequent processing quality indicators, but also react electrochemically with moisture in the environment to form localized corrosion micro-batteries, resulting in a secondary oxidation rate that is 2-3 times higher than the original state. Utility Model Content

[0004] The purpose of this utility model is to provide a rust removal machine for metallurgical shear blades, which solves the following technical problems: the blades lack an adaptive rotation mechanism, and the cutting angle needs to be adjusted manually throughout the process, which increases the time required for a single operation. Furthermore, after the rust removal process is completed, the shear blade surface will continue to be covered with iron filings and grinding dust due to the lack of an active cleaning device, resulting in secondary oxidation of the shear blade.

[0005] The objective of this utility model can be achieved through the following technical solution: it includes a machine body, a support frame is fixedly installed on the right side wall inside the machine body, a first fixing rod is symmetrically installed on the upper left side of the support frame, a second fixing rod corresponding to the first fixing rod is installed on the left side of the machine body, and a rust removal mechanism is installed in the middle of the machine body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-4 As shown, this utility model is a rust removal machine for metallurgical shear blades, including a machine body 1. A support frame 2 is fixedly installed on the right side wall inside the machine body 1. A first fixing rod 3 is symmetrically arranged on the upper left side of the support frame 2. A second fixing rod 4 matching the first fixing rod 3 is arranged on the left side inside the machine body 1. A metallurgical shear blade is clamped and fixed between the first fixing rod 3 and the second fixing rod 4. A rust removal mechanism 5 is arranged in the middle of the machine body 1. The rust removal mechanism 5 is used to reciprocate in the vertical direction to perform comprehensive rust removal on the metallurgical shear blade.

[0024] The bottom of the support frame 2 is provided with a first rotating disk 6. The first rotating disk 6 is driven to rotate by a servo motor provided on the outer side of the support frame 2. A second rotating disk 7 is provided above the first rotating disk 6. The second rotating disk 7 is in contact with the first rotating disk 6 and is fixedly connected to the first fixed rod 3. The first rotating disk 6 drives the second rotating disk 7 to rotate, thereby driving the first fixed rod 3 to rotate.

[0025] A support base 8 is fixedly installed on the left inner wall of the body 1. The support base 8 is flush with the support frame 2. A cylinder 9 is fixedly installed on one side wall of the support base 8. The cylinder 9 is perpendicular to the side wall of the support base 8. The end of the piston rod of the cylinder 9 is rotatably connected to the second fixed rod 4.

[0026] The rust removal mechanism 5 includes a hydraulic telescopic rod 10 fixed at the middle of the bottom of the machine body 1. A rust removal frame 11 is fixedly installed at the upper end of the hydraulic telescopic rod 10. The hydraulic telescopic rod 10 drives the rust removal frame 11 to move back and forth in the vertical direction, thereby achieving comprehensive rust removal of the blade. Rust removal rods 12 are symmetrically arranged at the upper end of the rust removal frame 11.

[0027] A motor housing 13 is fixedly installed on the left side of the rust removal frame 11. A motor 14 is fixedly installed inside the motor housing 13. The motor housing 13 is used to protect the motor 14. A first gear 15 is fixedly connected to the output shaft of the motor 14. A second gear 16 that meshes with the first gear 15 is provided on the left side of the rust removal rod 12. The other end of the rust removal rod 12 is rotatably connected to the inner side wall of the rust removal frame 11.

[0028] In summary, before using the rust removal machine, the metallurgical shear blade is placed between the first fixed rod 3 and the second fixed rod 4. The cylinder 9 drives the second fixed rod 4 to move horizontally, clamping and fixing the blade to prevent it from slipping during operation and affecting the operator's work. After clamping and fixing, the servo motor drives the first rotating disk 6 to rotate, which in turn drives the second rotating disk 7 to rotate until one side of the blade is flush with the rust removal rod 12. At this time, the hydraulic telescopic rod 10 lifts the rust removal rod 12 to the lower end of the blade. The motor 14 drives the first gear 15 to rotate, which in turn drives the second gear 16 meshing with the first gear 15 to rotate. The second gear 16 drives the two rust removal rods 12 to rotate and grind and remove rust from one side of the blade. After grinding and removing rust from one side of the blade, the servo motor drives the first rotating disk 6 to rotate to flexibly adjust the angle of the blade, thereby achieving grinding and rust removal on different sides of the blade and improving rust removal efficiency.

[0029] Example 2: Based on Example 1, please refer to... Figure 1-3As shown, a rectangular plate 17 is fixedly installed on the back of the machine body 1, and a connecting rod 18 is rotatably installed through one side of the machine body 1 into its interior. The connecting rod 18 can be moved horizontally reciprocally by hydraulic drive or manual push. A rectangular block 19 is fixedly installed at the end of the connecting rod 18, and a plurality of brushes 20 are arranged in an array on one side of the rectangular block 19. The brushes 20 are on the same horizontal line as the first fixed rod 3 and the second fixed rod 4.

[0030] The bottom of the body 1 has a through hole 21, and a collection box 22 is provided at the lower end of the through hole 21. A filter screen 23 is provided inside the collection box 22. The filter screen 23 and the collection box 22 are slidably connected. A door 24 is provided on the front side of the collection box 22 by a hinge. A vacuum cleaner 25 is provided at the bottom of the collection box 22.

[0031] A protective curtain 26 is provided on the front side of the machine body 1. The protective curtain 26 is used to prevent the spread of dust, grinding debris and sparks, and to protect the surrounding environment and equipment.

[0032] In summary, during the rust removal and grinding process, the vacuum cleaner 25 draws the fumes and metal shavings from the grinding process into the collection box 22 through the through hole 21. The filter screen 23 filters out the dust and grinding debris, preventing dust and other impurities from entering the vacuum cleaner 25. At the same time, excess gas is discharged for subsequent unified treatment, preventing dust, debris and other impurities from splashing and causing pollution to the surrounding environment or equipment. After the blade is rust removed and ground, the translation connecting rod 18 moves the rectangular block 19. The brush 20 on the side of the rectangular block 19 cleans the grinding surface of the blade. At the same time, the blade is rotated to complete the brushing of debris and dust on different grinding surfaces, preventing metal shavings, dust and rust residue from remaining on the blade surface, affecting the performance of the blade or even causing secondary rusting.
