Technical Field
The invention relates to the technical field of flange covers, in particular to a blind plate manufacturing method.
Background
The normal name of a blind plate (blind disk) is called a Flange cover (Flange cover), also called a blind Flange or a pipe plug. The flange is a flange without a hole in the middle, plays roles of isolation and cutting off, and is good in sealing performance, so that the flange is generally used as a reliable isolation means for a system needing complete isolation.
The side of the blind plate connected to the pipe is often subjected to high pressure, high temperature, corrosion, etc. due to the materials in the pipe. The traditional blind plate material selection needs to be carried out according to the materials in the pipeline, and the materials with high pressure resistance, high temperature resistance and corrosion resistance are high in price.
And carrying out plane cladding on one side of the pipe, which is in contact with the substance in the pipe, by a laser cladding technology on the premise that the basic strength is ensured by the improved blind plate design. The cladding layer meets the requirements of high pressure resistance, high temperature resistance, corrosion resistance and the like, so that the cost of the blind plate can be greatly reduced.
The laser cladding is a surface cladding layer formed by melting powder and the surface of a substrate by using a high-energy-density laser beam, and is mainly used for surface modification of materials, repair and remanufacture of damaged parts and rapid prototype manufacture. Because the forming process adopts a high-power heat source, the forming temperature has the characteristics of dynamic, time-varying and uneven, the air cooling eliminates the thermal stress after the laser cladding, the uneven expansion and contraction of the substrate and the forming surface cause the deformation of the substrate and the forming part, the deformation is shown as low middle and the warping deformation of two sides.

step 2: simultaneously carrying out laser cladding on the second side surfaces of the two blind plates to form a laser cladding layer;
and step 3: the two blind plates were separated.
Further, in step 1, the two blind plates have the same shape and thickness; and keeping the edges of the two blind plates aligned when the first sides of the two blind plates are subjected to back-to-back spot welding.
Further, in step 2, when laser cladding is simultaneously performed on the second side surfaces of the two blind plates, two laser heads are adopted, the two laser heads are respectively aligned to the second side surfaces of the two blind plates, laser operation is simultaneously started, and the axes of the two laser heads are always kept on the same straight line when the laser heads are moved.
Further, in the step 2, after the second side surfaces of the two blind plates are polished to be smooth, laser cladding is performed.
Further, in the step 3, the laser cladding layer comprises a nickel-based alloy layer and a hard alloy layer; and laser cladding nickel-based powder to the second side surface of the blind plate to form a nickel-based alloy layer, and laser cladding hard alloy powder to the surface of the nickel-based powder layer to prepare the hard alloy layer.
Furthermore, the thickness of the nickel-based alloy layer is 0.4-0.6 mm, and the thickness of the hard alloy layer is 0.6-0.8 mm.
Has the advantages that:
1) when laser cladding is carried out on the second sides of the two blind plates, the two sides are carried out simultaneously, the axes of the two laser heads are always on the same straight line, air cooling is carried out simultaneously after laser cladding to eliminate internal stress, and because the two blind plates are completely the same, the structure is symmetrical, the stress is uniform, and the two blind plates still keep a plane state, the invention can realize that the blind plate forming piece is not deformed after laser cladding is carried out on one side of the blind plate.
2) The nickel-based alloy layer has the characteristics of high temperature resistance and corrosion resistance, the hard alloy layer has extremely high hardness and wear resistance, and the nickel-based alloy layer and the hard alloy layer can modify one side of the blind plate connected with the pipeline, so that the blind plate has the characteristics of high temperature resistance, wear resistance, high pressure resistance and corrosion resistance, and the material cost is reduced.
