The invention belongs to the technical field of numerical control compound machines, and particularly relates to a horizontal numerical control lifting six-axis compound machine. The machining device comprises a numerical control compound machine table, three groups of power head assemblies installed on the numerical control compound machine table and machining heads arranged on the power head assemblies and used for machining the zinc alloy tee joint. The numerical control compound machine table is provided with a machining base used for supporting the zinc alloy tee joint and a top bearing table plate of the machining base. Wherein the outer side of the bearing bedplate is provided with a positioning adjusting seat which is designed to extend outwards. The adjustable V-shaped supporting structure and the semi-cylindrical contact plate are adopted, the device can be precisely attached to the root of the zinc alloy three-way pipe opening, stress is uniform, workpiece shaking and deviation during machining are effectively avoided, and the size precision and the surface quality are remarkably improved; the supporting position, the supporting height and the V-shaped opening angle can be independently adjusted, zinc alloy tee joints of different specifications, different pipe diameters and different angles can be rapidly adapted, model changing is convenient, and the equipment application range is greatly widened.

The invention discloses a distribution control method and application of replacement materials in a material demand plan and electronic equipment. The method comprises the following steps: step (1), dividing the replacement materials into I-type replacement materials, II-type replacement materials and III-type replacement materials; step (2), formulating different distribution strategies for the three replacement materials; (3) determining the type of the replacement material; step (4), selecting a corresponding distribution strategy for distribution according to the type of the replacement material; a distribution strategy of class I replacement materials: distributing all the current net demand quantity to the replacement materials with the maximum difference between the historical distribution quantity and the required distribution quantity; a distribution strategy of class II replacement materials: distributing all the current net demand quantity to the replacement materials with the lowest historical quota rating; and the allocation strategy of the class III replacement materials is that the replacement materials are sequentially allocated according to the quantity to be allocated from large to small by applying a batch rule. According to the invention, reasonable and efficient distribution of the replacement materials in the existing material demand plan can be ensured, and the requirements of the replacement material plan are met.

The present application belongs to the technical field of processing of steel bar welded mesh for ballastless track, in particular to a full-automatic steel bar welded mesh welding machine for ballastless track, comprising a processing platform, a mechanical hand mechanism and an angle adjusting mechanism, the processing platform is placed on the ground, the left side of the processing platform is provided with the mechanical hand mechanism, the right end of the mechanical hand mechanism is installed with the angle adjusting mechanism, the right end of the angle adjusting mechanism is installed with the mounting mechanism, the inside of the mounting mechanism is connected with the welding head replacement mechanism, the present application realizes full-automatic quick switching of three welding modes of laser welding, MIG welding and TIG welding, micron-level coaxiality installation of welding head and high-reliability mechanical locking, solves the defects of single welding mode of existing ballastless track steel bar mesh welding equipment, shutdown required for manual type replacement, insufficient working condition adaptability caused by poor welding head installation precision, poor consistency of welding point strength and inability to meet the full-scene welding requirements of ballastless track.

The present application belongs to the technical field of numerical control compound machine, especially horizontal numerical control lifting six-axis compound machine. The present application comprises numerical control compound machine platform, three groups of power head assemblies installed on the numerical control compound machine platform, and processing heads arranged on the power head assemblies for processing zinc alloy tee. The numerical control compound machine platform is provided with a processing seat for supporting the zinc alloy tee and a top bearing plate of the processing seat. The outer side of the bearing plate is provided with a positioning adjusting seat designed to expand outward. The present application adopts adjustable V-shaped supporting structure and semi-cylindrical contact plate, which can accurately fit the zinc alloy tee pipe opening root, uniformly bear stress, effectively avoid workpiece shaking and deviation during processing, significantly improve size accuracy and surface quality. The supporting position, height and V-shaped opening angle can be independently adjusted, which can quickly adapt to zinc alloy tees of different specifications, different pipe diameters and different angles, and the type replacement is convenient, which greatly improves the application range of the equipment.
