A profile conveying online fixed-length cutting device based on laser induction and a control method thereof
The application provides a profile conveying online fixed-length cutting device based on laser induction and a control method thereof, and belongs to the technical field of profile processing. The device comprises a rack, a conveying mechanism, a laser sensor, a cutting execution mechanism, a cutter retracting and releasing mechanism and an angle adjusting mechanism. The sliding seat is installed on the guide rail through rolling sliding blocks, and a vibration isolation pad is arranged between the guide rail and the rack. The cutter retracting and releasing mechanism drives the cutting tool to switch between the cutting position and the retracted position. The angle adjusting mechanism adjusts the cutting angle. The method comprises the following steps: electronically setting the cutting length, pre-accelerating the sliding seat to be synchronized with the conveying, keeping synchronization after the first laser triggering, triggering the cutting in advance by the controller, returning the sliding seat after cutting and self-adaptingly correcting the position deviation. The application solves the problems that the special-shaped cross-section profile cannot be cut off in one pass, dynamic matching is difficult and vibration conduction leads to precision deterioration.

Variable contact rolling-sliding composite bearing and design method
PendingCN122328449ACritical loadRolling sliding
This invention discloses a variable contact rolling-sliding composite bearing and its design method, relating to the field of bearing technology. The bearing includes an outer ring, an inner ring, bearing rollers, and a cage. The diameter of the bearing rollers is larger than the axial height of the cage to form an initial clearance. When the external load is small, the bearing rollers bear the load alone, and the bearing is in a pure rolling contact state. When the external load increases to the point that the bearing rollers undergo elastic deformation and the initial clearance closes, the end face of the cage contacts the raceway surface of the outer ring, sharing the load with the bearing rollers, and the bearing switches to a rolling-sliding composite contact state. The design method involves: calculating the roller deformation to determine the critical load; establishing a spring stiffness model for the rollers and cage to solve for the load distribution; checking whether the cage contact stress is lower than the yield limit; if it exceeds the limit, increasing the initial clearance and iteratively optimizing. This invention achieves adaptive switching of the bearing's operating mode, enabling low friction under light loads and high load capacity under heavy loads, and the design method is universal and reliable.

A modified disulfide-based composite film, preparation method and application thereof
This invention belongs to the field of lubricating materials technology, specifically relating to a modified disulfide-based composite film, its preparation method, and its application. The modified disulfide-based composite film of this invention comprises a matrix and a first metal oxide and a second metal oxide dispersed in the matrix; the first metal oxide includes one or more of WO3, TiO2, CaO, MoO3, Ta2O5, In2O3, Nb2O5, ZrO2, Cr2O3, and HaO2; the metal element in the second metal oxide is the same as that in the matrix. Introducing the first metal oxide into the matrix effectively refines the disulfide crystal particles and passivates active sites, thereby affecting its sensitivity to humid and hot conditions; through humid and hot storage treatment, the second metal oxide particles can be generated in situ, prompting them to transform the shear sliding of the WS2 film into a "rolling-sliding" cooperative mode during friction, reducing the coefficient of friction and improving its tribological properties.
