Abstract
Description
Technical Field
[0001] The invention relates to a metal laser cladding forging device capable of adjusting forging force and direction, belonging to the technical field of metal laser cladding forging. Background Art
[0002] Metal laser cladding and simultaneous high-frequency forging technology is an effective means of improving the overall performance of the cladding layer, such as density, hardness, and bonding strength. However, existing technology devices still have significant deficiencies in their application, which restrict their effectiveness. First, under given process parameters, such as the same forging motor, the instantaneous impact force that can be applied by the existing forging mechanism is often insufficient, resulting in insufficient plastic deformation of the metal pool, limited grain refinement, and failure to maximize the potential of forging strengthening. Second, and more critically, the position of the forging hammer head of the existing device is usually fixed, while the laser cladding head needs to move in multiple directions and complex trajectories according to the contour of the part during operation. This dynamic mismatch makes it impossible for the hammer head to accurately track the moving position of the cladding head in real time, making it difficult to ensure that the hammer head is always precisely located in the optimal forging area directly behind the cladding head's direction of travel. As a result, the forging action may deviate from the cladding layer or even fail, seriously weakening the process stability of the synchronous forging and the consistency of the strengthening effect.
[0003] Therefore, a metal laser cladding forging device is needed that can increase the forging force and at the same time ensure that the hammer head is always directly behind the advancing metal laser cladding head, ensuring that the hammer head can always forge the cladding layer. Summary of the Invention
