Description

Technical Field

[0001] The utility model belongs to the technical field of forging grinding, and relates to a forging grinding device with high precision. Background Art

[0002] During the forging process, the metal blank undergoes plastic deformation processing, which may leave some defects on the surface, such as protrusions, depressions, burrs, etc. These defects not only affect the appearance quality, but may also affect the mechanical properties and corrosion resistance of the forgings. Through grinding, these defects can be removed to make the surface smoother and smoother. Grinding can further refine the surface roughness of the forgings to meet the required surface quality requirements. The smaller the roughness, the smoother the surface, which can improve the fatigue strength, wear resistance and corrosion resistance of the forgings. During the grinding process of forgings, if the distance between the grinding head and the forging cannot be adjusted, it may cause a series of problems and affect the grinding quality and efficiency.

[0003] First, the non-adjustable distance means that the distance between the grinding head and the forging is fixed, but the surface roughness and shape of different forgings vary, and the fixed distance may not be able to adapt to various situations. When the grinding head is too far away, it may lead to insufficient grinding force and affect the grinding effect; when the grinding head is too close, it may lead to excessive grinding and even scratch the surface of the forging.

[0004] Secondly, the lack of distance adjustment may lead to heat accumulation. During the grinding process, metal dust and heat tend to accumulate between the grinding head and the forging. If the distance cannot be effectively adjusted to control heat dissipation and dust removal, it may cause overheating, deformation of the workpiece or damage to the grinding head.

[0005] In addition, the fixed distance also limits the grinding efficiency and flexibility. When faced with forgings of different shapes and sizes, the non-adjustable grinding head may not be able to adapt to various workpieces, resulting in low grinding efficiency. For some forgings of special shapes, the fixed distance may even make it impossible to complete the grinding work.

[0006] Furthermore, from a safety perspective, an unadjustable distance will increase operational risks. When facing certain large or special-shaped forgings, a too close distance may make it difficult for the operator to control the grinding head, increasing the difficulty and danger of the operation.

[0007] In summary, the inability to adjust the distance between the grinding head and the forging during the forging grinding process will not only affect the grinding quality and efficiency of the workpiece, but may also cause overheating, damage to the workpiece or equipment, and increase operational risks. Therefore, a high-precision forging grinding device is urgently needed to solve the above problems. Utility Model Content
