Abstract

The present invention provides a manufacture technique for hexagonal honeycomb devices. First, stainless steel sheets are used for manufacturing hexagonal pipes, walls of the adjacent hexagonal pipes are connected by spot welding, so the hexagonal pipes are assembled as unit bodies, and a honeycomb plate is spliced and welded on a steel platform by the unit bodies; subsequently, the honeycomb plate is arranged in a frame, and irregular edge pipes are used for filling connection points of the frame and the honeycomb plate so as to manufacture honeycomb blocks; finally, the honeycomb blocks are arranged in a processed framework, and barrier strips are fixed on the framework so as to form the honeycomb device. The present invention has the advantages of low cost, high work efficiency and very high precision and can be widely used in the fields which need tease and rectify gases and fluid, such as aerodynamic test devices, pressure vessels, cooling devices, etc.

Description

The manufacturing process of hexagonal honeycomb device

The present invention relates to a kind of hydrodynamics experimental rig, particularly relate to a kind of manufacturing process of hexagonal honeycomb device,

Honeycomb is generally made with seamless steel pipe both at home and abroad, and its assembling is to make through heating pressurization with glue, and cost is high.

The objective of the invention is to overcome above-mentioned shortcoming, provide that a kind of cost is low, work efficiency is high, and the manufacturing process of the high hexagonal honeycomb device of product precision.

The manufacturing process operating procedure of hexagonal honeycomb device of the present invention is as follows: 1) make the hexagonal pipe with the stainless steel roll bending; 2) on the plug of assembly jig, insert the hexagonal pipe that has been shaped by root, make hexagonal pipe lower surface be adjacent to the assembly jig base plate, smooth to guarantee transverse plane, with the adjacent hexagonal tube wall of special mash welder spot welding, general every millet cake welds 8 points, make several hexagonal pipes connect into an overall structure, it is assembled into cell cube; 3) several cell cubes are welded into cellular board on the steel platform; 4) cellular board is put into frame, cellular board is generally than the little 1～2mm of frame, border width is identical with the hexagonal length of tube, pipe of spot welding hexagonal then and frame, hexagonal pipe and frame are linked together, and frame shields to the hexagonal pipe, is convenient to transportation and installs, then fill spot welding with the frame junction, make honeycomb block with the broken edge pipe; 5) honeycomb block is put into the framework that processes, and be fixed on the framework, generally adopt flat head screw to fix, be made into honeycomb at last, and the honeycomb end face should be vertical with blend stop.Wherein, the concrete steps of making the hexagonal pipe of the stainless steel roll bending are, at first the stainless steel roll bending are struck out square stock on blanking die, again square stock are struck out cross section in the finishing die I and are Semi-finished product are pressed into the hexagonal pipe with semi-finished product again in the finishing die II, it is orthopedic then the hexagonal pipe to be pressurizeed on orthoplastic casts, at last on seam welder with the butt welding of hexagonal pipe longitudinal joint.

The advantage of the manufacturing process of hexagonal honeycomb device of the present invention is to substitute seamless pipe with the coil plate, and reach designing requirement, cost is low, the work efficiency height, product reaches high grade, to need to be widely used in the fields such as aerodynamic experiment device, pressure vessel, cooling device to gas, fluid carry out the combing rectification field boundary close.

Describe the embodiment of the invention in detail below in conjunction with accompanying drawing.

Its step of the manufacturing process of hexagonal honeycomb device of the present invention is, 1) selects thickness 0.2mm for use, wide 206mm stainless steel roll bending 1 strikes out 68.5 * 200mm square stock 3 (as shown in Figure 1) on blanking die 2, above-mentioned square stock 3 is struck out length in the shaping mould I be 200mm, and cross section is Semi-finished product 4 (as shown in Figure 2), semi-finished product 4 are pressed into hexagonal pipe 5 (as shown in Figure 3) in the shaping mould II, it is orthopedic that hexagonal pipe 5 is pressurizeed on orthoplastic casts 6, makes physical dimension reach design accuracy (as shown in Figure 4), at last on seam welder with the butt welding of hexagonal pipe longitudinal joint.2) on the plug 8 of assembly jig 7, insert the hexagonal pipe 5 that has been shaped by root, per 10 is a row, totally 100 hexagonal pipes 5 of 10 rows form a cell cube, make hexagonal pipe 5 lower surfaces be adjacent to assembly jig 7 base plates, tube wall with the special adjacent hexagonal pipe 5 of mash welder spot welding, every millet cake welds 8 points, makes several hexagonal pipes 5 connect into an overall structure (as Fig. 5～shown in Figure 7).3) several cell cubes are welded into cellular board on the steel platform; 4) cellular board is put into stainless steel frame 9, cellular board is than frame 9 little 2mm, and frame 9 width are identical with hexagonal pipe 5 length, then fills spot welding with broken edge pipe 10 with frame 9 junctions, makes honeycomb block 11 (as shown in Figure 8).5) honeycomb block 11 is put into the framework 12 that processes, both sides are close to blend stop 13, and blend stop 13 usefulness flat head screws 14 are fixed on (as Fig. 9, shown in Figure 10) on the framework 12, and last framework is installed in the wind-tunnel housing 15, is made into honeycomb (as shown in figure 11).Its technical indicator is as shown in table 1.
