[0002] Forging requires heating, and the oxidation of the forging at high temperatures forms a corrosion product called oxide scale. Oxide scale is brittle, lacks ductility, and has high hardness, which accelerates the wear and deformation of forging dies, seriously affecting the service life of dies and the appearance quality of products. Currently, oxide scale is generally not removed during the forging process, or it is scraped off manually.

The device includes a grinding mechanism, a rotating mechanism, a pressing mechanism, a driving mechanism, a pushing mechanism, a dust removal mechanism, and a cleaning mechanism. The pressing mechanism is installed at the top of the rotating mechanism, the driving mechanism is installed on the pressing mechanism, the pushing mechanism is installed at the top of the rotating mechanism, the grinding mechanism is installed on the pushing mechanism, the dust removal mechanism is installed on the rotating mechanism, and the cleaning mechanism is installed inside the dust removal mechanism. The rotating mechanism drives the irregular parts to rotate, and the driving mechanism drives the pressing mechanism to fix the top of the irregular parts.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, the aforementioned equipment, when applied, can solve the problem that existing technologies can only remove oxide scale from large areas such as the top and bottom of castings, but are not convenient for removing oxide scale from thinner and irregular sides of castings, thus reducing practicality.

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0022] Example 1: Refer to Figure 1-3 This is the first embodiment of the present invention, providing a scale removal device for small and medium-sized forgings, including a cleaning mechanism 1. The cleaning mechanism 1 includes a cleaning table 11, a sliding plate 12, a mounting frame 13, a motor 14, and a grinding head 15. The sliding plate 12 is fixedly connected to the right side of the top of the cleaning table 11, the mounting frame 13 is movably connected to the inner wall of the sliding plate 12, the motor 14 is fixedly mounted on the top of the mounting frame 13, and the grinding head 15 is located at the bottom of the motor 14. Quick-change mechanism 2; Quick-change mechanism 2 includes a replacement seat 21, which is fixedly connected to the output end of the motor 14. A replacement slot 22 is provided at the bottom of the replacement seat 21. A replacement block 23 is movably connected to the inner wall of the replacement slot 22. The bottom of the replacement block 23 is fixedly connected to the top of the grinding head 15. A sliding groove 24 is provided at the bottom of the replacement seat 21. Disassembly and assembly components 25 are movably connected to both sides of the inner wall of the sliding groove 24. Adjustment components 26 are provided on both sides of the inner wall of the sliding groove 24. Auxiliary replacement mechanism 3; the auxiliary replacement mechanism 3 is provided on both sides of the top of the inner wall of the slide 24. The disassembly and assembly component 25 includes disassembly and assembly blocks 251, which are movably connected to both sides of the inner wall of the slide 24. Disassembly and assembly slots 252 are provided on both sides of the replacement block 23. The inner side of the disassembly and assembly block 251 is inserted into the inner wall of the disassembly and assembly slot 252. The adjustment component 26 includes rotating holes 261, which are provided on both sides of the inner wall of the slide 24. The inner wall of the rotating holes 261 is movably connected to a bidirectional lead screw 26 via bearings. 2. The surface of the disassembly block 251 is provided with threaded holes 263. The two sides of the surface of the bidirectional lead screw 262 are threadedly connected to the inner wall of the threaded holes 263. Both sides of the disassembly block 251 are movably embedded with balls 4. Both sides of the inner wall of the slide groove 24 are provided with movable grooves 5. The surface of the balls 4 is movably connected to the inner wall of the movable grooves 5. Both sides of the bidirectional lead screw 262 are fixedly connected with rotating blocks 6. The surface of the rotating blocks 6 is provided with anti-slip grooves 7. The number of anti-slip grooves 7 is set in several groups and is distributed in a ring at equal distances.

[0023] Specifically, the quick-change mechanism 2 can quickly detach and install the grinding head 15 and the output end of the motor 14 without additional tools, which greatly shortens the time for replacing the grinding head 15, avoids long-term interruption of the descaling process due to replacement operations, and significantly improves overall production efficiency.

[0024] Furthermore, firstly, the grinding head 15 to be replaced is aligned with the replacement slot 22 at the bottom of the replacement seat 21 at the output end of the motor 14 via the replacement block 23 fixed on its top. Then, the replacement block 23 is inserted into the replacement slot 22 to complete the initial positioning and docking of the grinding head 15 and the replacement seat 21. Then, the user rotates the rotating blocks 6 with anti-slip grooves 7 on both sides of the bidirectional lead screw 262. At the same time, the anti-slip grooves 7 can increase the friction between the rotating blocks 6 and the hand to prevent slippage. The bidirectional lead screw 262 rotates stably through the bearing in the rotating hole 261. Since the threaded hole 263 on the surface of the disassembly block 251 is adapted to the threads on both sides of the surface of the bidirectional lead screw 262, when the bidirectional lead screw 262 rotates, it will drive the disassembly blocks 251 on both sides of the inner wall of the slide groove 24 to move towards each other along the slide groove 24. The ball bearings 4 embedded on both sides of the disassembly block 251 roll along the movable groove 5, which can reduce the frictional resistance when the disassembly block 251 moves, so that... The movement is smoother. When the disassembly block 251 moves to the inside and inserts into the disassembly slots 252 on both sides of the replacement block 23, the rotation of the rotating block 6 stops. At this time, the insertion and engagement of the disassembly block 251 and the disassembly slot 252 stably limits the replacement block 23 in the replacement slot 22, thereby realizing the fixed installation of the grinding head 15 and the output end of the motor 14. The whole process does not require the use of wrenches or other additional tools, and the grinding head 15 is quickly assembled. When it is necessary to disassemble the grinding head 15, the rotating block 6 is rotated in the opposite direction. The bidirectional screw 262 drives the disassembly block 251 to move in the opposite direction along the slide 24, so that the disassembly block 251 is disengaged from the disassembly slot 252 on the replacement block 23, and the limitation on the replacement block 23 is released. Then the grinding head 15 together with the replacement block 23 can be taken out from the replacement slot 22, realizing the quick disassembly of the grinding head 15, greatly shortening the replacement time and avoiding interruption of the descaling process.

[0025] Example 2: In the second embodiment of this utility model, the auxiliary replacement mechanism 3 includes a receiving groove 31, which is opened on both sides of the top of the inner wall of the slide 24. A spring 32 is provided inside the receiving groove 31. One end of the spring 32 is fixedly connected to the top of the inner wall of the receiving groove 31, and the other end of the spring 32 is fixedly connected to an auxiliary push block 33. The auxiliary push block 33 is located on both sides of the top of the replacement block 23. Limiting components 34 are fixedly connected on both sides of the auxiliary push block 33. The limiting components 34 include limiting rods 341, which are fixedly connected to both sides of the auxiliary push block 33. A limiting groove 342 is opened on the top of the inner wall of the slide 24, and the surface of the limiting rod 341 is movably connected to the inner wall of the limiting groove 342.

[0026] Specifically, the auxiliary replacement mechanism 3 can provide an active separation thrust for the grinding head 15, helping the grinding head 15 to quickly detach from the replacement seat 21, avoiding disassembly difficulties caused by the tight fit of parts after long-term use, and reducing the manual force required by the operator.

[0027] Furthermore, when the replacement block 23 is inserted into the replacement slot 22 of the replacement seat 21, the top of the replacement block 23 contacts the bottom of the auxiliary push block 33 and pushes the auxiliary push block 33 upward. The auxiliary push block 33 compresses the spring 32 in the receiving groove 31. At this time, the limiting rods 341 on both sides of the auxiliary push block 33 slide synchronously along the limiting grooves 342 at the top of the inner wall of the slide groove 24, ensuring that the auxiliary push block 33 moves only in the vertical direction and avoids deviation. The compression deformation of the spring 32 generates a reverse elastic force, so that the auxiliary push block 33 always fits against the top of the replacement block 23, which plays a guiding role in the insertion process of the replacement block 23 and assists in the replacement. Block 23 precisely aligns with the replacement slot 22, improving installation and positioning accuracy. When the grinding head 15 is disassembled, the compressed spring 32 in the receiving groove 31 releases its elasticity, pushing the auxiliary push block 33 downward along the limiting groove 342. The auxiliary push block 33 applies a downward pushing force to the top of the replacement block 23. This pushing force helps the replacement block 23 quickly disengage from the replacement slot 22 of the replacement seat 21, avoiding disassembly difficulties caused by the replacement block 23 and the replacement slot 22 being tightly fitted after long-term use. This reduces the force required for operators to manually pull out the grinding head 15, further improving the ease of disassembling the grinding head 15.

[0028] Working principle: First, the grinding head 15 to be replaced is aligned with the replacement slot 22 at the bottom of the replacement seat 21 at the output end of the motor 14 via the replacement block 23 fixed on its top. Then, the replacement block 23 is inserted into the replacement slot 22 to complete the initial positioning and docking of the grinding head 15 and the replacement seat 21. Then, the user rotates the rotating blocks 6 with anti-slip grooves 7 on both sides of the bidirectional lead screw 262. At the same time, the anti-slip grooves 7 can increase the friction between the rotating blocks 6 and the hand to prevent slippage. The bidirectional lead screw 262 rotates stably through the bearing in the rotating hole 261. Since the threaded hole 263 on the surface of the disassembly block 251 is compatible with the threads on both sides of the surface of the bidirectional lead screw 262, when the bidirectional lead screw 262 rotates, it will drive the disassembly blocks 251 on both sides of the inner wall of the slide groove 24 along the slide groove 262. 4. The balls 4 embedded on both sides of the disassembly block 251 roll along the movable groove 5, which reduces the frictional resistance when the disassembly block 251 moves, making the movement smoother. When the disassembly block 251 moves to the point where it is inserted into the disassembly groove 252 on both sides of the replacement block 23, the rotating block 6 stops rotating. At this time, the insertion and engagement of the disassembly block 251 and the disassembly groove 252 stably limits the replacement block 23 in the replacement slot 22, thereby realizing the fixed installation of the grinding head 15 and the output end of the motor 14. The whole process does not require the use of wrenches or other additional tools to complete the quick assembly of the grinding head 15. When it is necessary to disassemble the grinding head 15, the rotating block 6 is rotated in the opposite direction, and the bidirectional screw 262 drives the disassembly block 251 to move in the opposite direction along the slide groove 24, so that the disassembly and assembly can be completed. Block 251 disengages from the disassembly slot 252 on the replacement block 23, releasing the restriction on the replacement block 23. The grinding head 15, along with the replacement block 23, can then be removed from the replacement slot 22, enabling rapid disassembly of the grinding head 15, significantly shortening replacement time and avoiding interruption of the descaling process. During the installation of the grinding head 15, the top of the replacement block 23 contacts the bottom of the auxiliary push block 33 and pushes it upwards. The auxiliary push block 33 compresses the spring 32 in the receiving slot 31. At this time, the limiting rods 341 on both sides of the auxiliary push block 33 slide synchronously along the limiting grooves 342 at the top of the inner wall of the slide groove 24, ensuring that the auxiliary push block 33 moves only in the vertical direction to avoid deviation. The compression deformation of the spring 32 generates a reverse elastic force. The auxiliary push block 33 is always in contact with the top of the replacement block 23, which guides the insertion of the replacement block 23. The auxiliary replacement block 23 is precisely aligned with the replacement slot 22, improving the installation and positioning accuracy. When the grinding head 15 is disassembled, the compressed spring 32 in the receiving groove 31 releases its elasticity, pushing the auxiliary push block 33 downward along the limiting groove 342. The auxiliary push block 33 applies a downward pushing force to the top of the replacement block 23. This pushing force helps the replacement block 23 to quickly disengage from the replacement slot 22 of the replacement seat 21, avoiding disassembly difficulties caused by the replacement block 23 being tightly attached to the replacement slot 22 after long-term use. It also reduces the force required for the operator to manually pull out the grinding head 15, further improving the convenience of disassembling the grinding head 15.

[0029] In summary, by setting up the quick-change mechanism 2 and the auxiliary change mechanism 3, the quick-change mechanism 2 enables the rapid disassembly and assembly of the grinding head 15 and the output end of the motor 14, significantly shortening the replacement time of the grinding head 15, avoiding long-term interruptions in the descaling process due to the replacement operation, and significantly improving overall production efficiency. It also solves the problem that existing grinding heads are mostly fixed to the motor output end by multiple sets of bolts, requiring the use of wrenches and other tools to remove the bolts one by one during replacement, which is time-consuming and labor-intensive, seriously interrupting the descaling process and reducing overall production efficiency, thus achieving the effect of easy replacement.
