Description

Technical Field

[0001] The invention relates to the technical field of honeycomb structure processing, in particular to a method for processing a honeycomb structure ring. Background Art

[0002] In aircraft engines, internal combustion engines, steam turbines and other machines, the main function of the honeycomb sealing structure is to prevent the internal and external leakage of the working medium, lubricating medium or cooling medium of the high-speed moving shaft system, so as to improve efficiency, save energy and achieve safe and stable operation. Figure 1 shown.

[0003] In the honeycomb seal structure, the gap between the honeycomb and the seal body is strictly required, so the inner diameter of the honeycomb is required to be extremely high. Usually the diameter tolerance is only about 0.1mm, and the runout requirement is 0.04~0.08. Figure 2 As shown. Currently, honeycombs are generally processed by electric spark grinding, and a few are processed by grinding wheel grinding, but both have the following disadvantages:

[0004] The EDM process is slow, takes a long time, and is easy to burn the honeycomb structure. It will also produce a remelting layer and spherical remelting materials adhering to the honeycomb hole wall and hole bottom. Figure 3 As shown, the remelted layer and remelted material need to be cleaned with a pick under a magnifying glass, which increases the workload of the operator and prolongs the processing period.

[0005] The efficiency of grinding wheel grinding is similar to that of electric spark grinding, and the burrs produced by the processing are difficult to remove completely. If the processing is fast, it is easy to cause the honeycomb structure to tear. Figure 4 shown. Summary of the invention

[0006] The present invention provides a method for processing a honeycomb structure ring to solve the technical problems of the existing electric spark grinding and grinding wheel grinding, such as slow processing speed, long time required, generation of a remelted layer and spherical remelted materials adhering to the honeycomb hole wall and hole bottom without subsequent treatment, and difficulty in removing the burrs generated by the processing.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A method for processing a honeycomb structure ring comprises the following steps: fixing the honeycomb structure sheet: clamping and fixing the honeycomb structure sheet arranged to form a honeycomb structure ring to be processed onto a positioning and fixing device arranged in a vibration filling device, and making the unclosed core cell openings on the honeycomb structure sheet face upward; filling with soft materials: filling the core cells with dense and compact soft materials by combining the vibration filling device with manual operation; removing excess and ensuring size: turning the inner ring surface of the honeycomb structure ring combined into a ring shape by turning to remove burrs and ensure dimensional accuracy; removing filling materials: removing the soft materials filled in the processed honeycomb structure ring.

[0009] Furthermore, the positioning and fixing device is used to adaptively clamp and fix honeycomb structure sheets of different numbers, shapes and sizes.

[0010] Furthermore, the positioning and fixing device includes a mounting base plate for detachably fixing to the vibration filling equipment, two fastening unit walls arranged relatively at intervals, and an elastic connecting member that acts as an elastic connection; the first fastening unit wall is vertically fixedly supported on the mounting base plate, and the second fastening unit wall is vertically and slidably supported on the mounting base plate, and the two fastening unit walls are used to adaptively deform according to the shape of the clamped honeycomb structure sheet so as to relatively stably clamp the honeycomb structure sheet; the elastic connecting member is connected between the two fastening unit walls to relatively tighten the two fastening unit walls.

[0011] Furthermore, the fastening unit wall includes a support plate vertically supported on the mounting base plate, a plurality of fastening unit rods vertically inserted through the support plate and sliding, and an elastic skin for limiting the fastening unit rods; the elastic skin is fixed on the outer facade of the support plate, and elastically presses against the protruding ends of the fastening unit rods to press the fastening unit rods toward the inner facade of the support plate.

[0012] Furthermore, the fastening unit rod includes an outward extension section and an inner top section which are arranged and connected in sequence along the axial direction, the outward extension section is used to push against the elastic skin, the inner top section is used to push against the honeycomb structure sheet, and the outer diameter of the outward extension section is larger than the outer diameter of the inner top section; a step hole is provided on the support plate for the fastening unit rod to pass vertically and which is adapted to the outer diameters of the outward extension section and the inner top section, so as to limit the fastening unit rod from being pushed out of the support plate under the action of the elastic skin.

[0013] Furthermore, the step of "soft material filling" specifically includes the following steps: dry filling: automatically filling the core cells of the honeycomb structure sheet with dry soft materials through a vibration filling device; wet filling: filling the core cells with compacted and moistened soft materials through a combination of vibration filling equipment and manual operation; drying: drying the moistened soft material to enhance the overall rigidity of the honeycomb structure sheet.

[0014] Furthermore, the step of "wet filling" specifically includes the following steps: humidification: humidifying and vibrating the honeycomb structure sheet through a vibration filling device to moisten and compact the soft material filled in the core cell; filling paste: preparing a paste of the soft material to fill and compact the empty section in the core cell.

[0015] Furthermore, the step of "removing excess and ensuring size" specifically includes the following steps: rough machining: rough turning the inner ring surface of the combined honeycomb structure ring to remove the excess; fine machining: fine machining the inner ring surface of the honeycomb structure ring after rough turning to remove burrs and ensure machining dimensional accuracy.

[0019] In the processing method of the present invention, a positioning and fixing device is used to clamp and fix the honeycomb structure sheet to be filled, so as to avoid the honeycomb structure sheet being loosened due to vibration when the vibration filling equipment is vibrating, causing the core cell opening that should be facing upward to tilt to one side, thereby affecting the filling of the core cell with the soft material, resulting in a long filling time for the soft material, and the core cell is easily not filled after the filling is completed, which in turn leads to a long subsequent paste filling time, a large amount of paste filling, and difficulty in operation, and a poor paste filling effect; in the processing method of the present invention, the core cell is filled with soft material, and the core cell is filled with dense and compact soft material after the filling is completed, thereby improving the rigidity of the honeycomb structure sheet, avoiding damage to the honeycomb structure ring due to insufficient rigidity during processing, and also enabling the honeycomb structure ring to be processed by turning due to the characteristics of sufficient rigidity and easy turning of the material itself, thereby not only greatly improving the processing efficiency of the inner diameter of the honeycomb structure ring, the processing efficiency can reach about 5 times that of electric spark grinding and grinding wheel grinding, and can effectively reduce burrs generated during processing, which is convenient for reducing subsequent workload.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0040] Reference Figure 5 , Figure 8-10 , Figure 14-15 The preferred embodiment of the present invention provides a method for processing a honeycomb structure ring, comprising the following steps:

[0041] Fixing of the honeycomb structure sheet 1: The honeycomb structure sheet 1 arranged to form a honeycomb structure ring to be processed is clamped and fixed to the positioning and fixing device 3 provided in the vibration filling equipment 2, and the unclosed core cell openings 102 of the core cells 101 on the honeycomb structure sheet 1 are facing upward.

[0042] Filling with soft materials: The core cell 101 is filled with dense and compact soft materials by combining the vibration filling device 2 with manual operation.

[0043] Residue removal and size assurance: The inner ring surface of the honeycomb structure ring combined into a ring shape is turned by turning to remove burrs and ensure dimensional accuracy.

[0044] Filling material removal: remove the soft material filled in the processed honeycomb structure ring.

[0045] In the processing method of the present invention, a positioning and fixing device 3 is used to clamp and fix the honeycomb structure sheet 1 to be filled, so as to prevent the honeycomb structure sheet 1 from being loosened due to vibration when the vibration filling device 2 is vibrating, causing the core cell opening 102 on the core cell 101, which should originally face upward, to tilt to one side, thereby affecting the filling of the core cell 101 with the soft material, resulting in a long filling time for the soft material, and the core cell 101 is easily not filled after the filling is completed, thereby resulting in a long subsequent paste filling time, a large amount of paste filling, and difficult operation, and a poor paste filling effect; in the processing method of the present invention, the soft material is used to fill the core cell 101 with the soft material. The core cell 101 is filled with the material, and after the filling, the core cell 101 is filled with dense and tight soft material, thereby improving the rigidity of the honeycomb structure sheet 1, avoiding damage to the honeycomb structure ring due to insufficient rigidity during machining, and making the honeycomb structure ring capable of being machined by turning due to its sufficient rigidity and easy turning of its own material, thereby greatly improving the machining efficiency of the inner diameter of the honeycomb structure ring, which can reach about 5 times that of electric spark grinding and grinding wheel grinding, and can effectively reduce the burrs generated during the machining process, thereby reducing the subsequent workload.

[0046] Alternatively, if Figure 5 As shown, the positioning and fixing device 3 is used to adaptively clamp and fix honeycomb structure sheets 1 of different numbers, shapes and sizes, so that honeycomb structure sheets 1 of arbitrary shapes within a certain diameter size range can be clamped and fixed using the positioning and fixing device 3 of the present invention, and multiple honeycomb structure sheets 1 can be clamped and fixed at the same time, thereby greatly improving the application scope of the positioning and fixing device 3 and reducing the processing cost.

[0047] In this option, if Figure 5 As shown, the positioning and fixing device 3 includes a mounting base plate 31 for detachably fixing with the vibration filling device 2, two fastening unit walls 32 arranged relatively at intervals, and an elastic connecting member 33 for elastic connection. The first fastening unit wall 32 is vertically fixedly supported on the mounting base plate 31, and the second fastening unit wall 32 is vertically and slidably supported on the mounting base plate 31. The two fastening unit walls 32 are used to adaptively deform according to the shape of the clamped honeycomb structure sheet 1 to relatively stably clamp the honeycomb structure sheet 1. The elastic connecting member 33 is connected between the two fastening unit walls 32 to relatively tighten the two fastening unit walls 32. During clamping, the honeycomb structure sheet 1 is placed between two relative fastening unit walls 32 by moving the sliding fastening unit walls 32, and then the two fastening unit walls 32 adaptively deform according to the shape of the honeycomb structure sheet 1 so that the honeycomb structure sheet 1 is clamped between the two relative fastening unit walls 32 through the honeycomb mounting ears 11 thereon, and finally the two relative fastening unit walls 32 are relatively tightened by the elastic connecting member 33, so that the honeycomb structure sheet 1 is stably fixed between the two fastening unit walls 32, thereby realizing the rapid filling of the core cell 101 of the honeycomb structure sheet 1.

[0048] Preferably, a guide rail is provided on the mounting base plate 31, and the bottom of the sliding fastening unit wall 32 cooperates with the guide rail through a slide groove to limit and guide the sliding of the fastening unit wall 32, and the sliding fastening unit wall 32 can adapt to the clamping and fastening of honeycomb structure sheets 1 of different sizes.

[0049] In this option, if Figure 5 As shown, the fastening unit wall 32 includes a support plate 321 vertically supported on the installation base plate 31, a plurality of fastening unit rods 322 vertically penetrated through the support plate 321 and slide, and an elastic skin 323 for limiting the fastening unit rods 322. The elastic skin 323 is fixed on the outer facade of the support plate 321, and elastically presses against the protruding end of the fastening unit rod 322 to press the fastening unit rod 322 toward the inner facade of the support plate 321. During operation, it is only necessary to slide the sliding support plate 321 away from the fixed support plate 321, and then put the honeycomb structure sheet 1 into a suitable position between the two fastening unit walls 32, and then slowly release the sliding support plate 321. The positioning and fixing device can automatically complete the fastening under the action of the elastic connector 33 and the elastic skin 323, and the fastening unit wall 32 can adapt to honeycomb structure sheets 1 of different shapes, sizes, and quantities, such as Figure 6 shown.

[0050] In a specific embodiment of this optional solution, Figure 5 As shown, the fastening unit rod 322 includes an outward extension section and an inner top section which are sequentially arranged and connected along the axial direction, the outward extension section is used to abut against the elastic skin 323, the inner top section is used to abut against the honeycomb structure sheet 1, and the outer diameter of the outward extension section is greater than the outer diameter of the inner top section. The support plate 321 is provided with a stepped hole for the fastening unit rod 322 to vertically pass through and adapted to the outer diameters of the outward extension section and the inner top section, so as to limit the fastening unit rod 322 from being pushed out of the support plate 321 under the action of the elastic skin 323.

[0051] Optionally, in the present invention, the soft material is a soft material similar to graphite, such as Ni-Al powder, etc., to increase the rigidity of the honeycomb structure sheet 1 and strengthen the strength of the wall of the honeycomb structure sheet 1, so that the turning processing method with higher processing efficiency and relatively low threshold can be used to complete the excess processing and ensure the size; and because the core cell 101 is a semi-closed structure, and the depth to width ratio of the honeycomb structure sheet 1 before processing can usually reach about 5 / 1, such as Figure 7-8 As shown, since it is relatively difficult to directly fill the soft material, in the present invention, the soft material filling is performed by combining dry filling and wet filling. Therefore, in the present invention, the step of "soft material filling" specifically includes the following steps:

[0052] Dry filling: The core cells 101 of the honeycomb structure sheet 1 are automatically filled with dry soft materials through the vibration filling device 2. Specifically, dry filling is a vibration filling method, i.e. the honeycomb structure sheet 1 to be filled with soft materials is clamped and fixed in the positioning and fixing device 3 of the vibration filling device 2, and the core cell opening 102 of the honeycomb structure sheet 1 is facing upward, and a proper amount of soft material powder is put into the container of the vibration filling device 2, and the powder must cover the honeycomb structure sheet 1 to a certain depth; then the container is connected as a whole to the vibration device at the bottom for vibration, so that the soft material can be fully filled into the core cells 101, and the vibration amplitude, frequency and time are determined according to the specific conditions of the honeycomb structure sheet 1 and the soft material powder. The container needs to be closed during the vibration process to avoid dust, such as Fig. 9 shown.

[0053] Wet filling: The core cell 101 is filled with the soft material that is compacted and moistened by combining the vibrating filling device 2 and manual operation. After the dry filling is completed, the soft material powder will fill the core cell 101 of the honeycomb structure sheet 1, but at this time the soft material is relatively soft in the core cell 101, and the effect of strengthening the rigidity of the honeycomb structure sheet 1 is limited. Therefore, wet filling is required to fill the core cell 101 with the soft material that is compacted and moistened, so as to further improve the rigidity of the honeycomb structure sheet 1.

[0054] Drying treatment: The wet soft material is dried to enhance the overall rigidity of the honeycomb structure sheet 1. Specifically, after the soft material is filled, it needs to be air-dried or dried. The strength of the soft material will increase as the moisture content decreases, but if it is over-baked, the strength will decrease, which is not convenient for subsequent processing. The specific air-drying or drying temperature and time are determined according to actual conditions.

[0055] In this optional solution, the step of "wet filling" specifically includes the following steps:

[0056] Wetting: The honeycomb structure sheet 1 is wetted and vibrated by the vibrating filling device 2 to wet and compact the soft material filled in the core cell 101. Specifically, the dry-filled soft material powder is first processed, that is, the excess soft material powder in the container is first removed, and then the container is sprayed with water mist while vibrating to wet the soft material powder in the core cell 101. Fig.10 As shown, the filling condition of the soft material in the core cell 101 before infiltration is as shown Fig.11 As shown, the filling condition of the soft material in the core cell 101 after spray infiltration is as follows Fig.12 shown.

[0057] Filling paste: Prepare a paste of soft material to fill and compact the empty section in the core cell 101. Specifically, as the powder infiltrates and vibrates, the soft material in the core cell 101 will gradually become compact, but its filling rate in the core cell 101 will also gradually decrease. Figure 11-12As shown, it is necessary to supplement the soft material, so that the paste prepared by mixing the soft material with water is used to fill and compact the empty sections in the core cell 101, so as to further improve the compactness of the soft material in the core cell 101, in preparation for further improving the rigidity of the honeycomb structure sheet 1.

[0058] Alternatively, if a paste-like soft material is directly used for filling, since the core cell 101 of the honeycomb structure sheet 1 is a semi-enclosed structure and the depth and width of the core cell 101 are relatively large, an airtight effect will be formed after filling, resulting in that the bottom of the core cell 101 cannot be filled. Fig.13 shown.

[0059] Optionally, the step of “residue removal and size assurance” specifically includes the following steps:

[0060] Rough machining: The inner ring surface of the combined honeycomb structure ring is rough machined to remove the excess.

[0061] Finishing: The inner surface of the honeycomb structure ring after rough turning is further finished to remove burrs and ensure the processing size accuracy.

[0062] Specifically, compared with electric spark grinding and grinding wheel grinding, the inner diameter material of the honeycomb structure ring needs to be ground into powder layer by layer. In the present invention, the honeycomb structure ring after filling with soft material can be processed by turning due to the improved rigidity, and because the honeycomb structure sheet ring is relatively easy to cut, it can be processed with a large cutting depth. Therefore, during processing, only one rough machining is required to remove the excess, and one fine machining is required to remove burrs and ensure the size. The processing efficiency is high, which can reach about 5 times that of electric spark grinding and grinding wheel grinding. Moreover, since the core grid 101 is filled with soft material, burrs are not easy to be generated on the processed surface. Only a few burrs will be generated on the edge of the cut-out part, which is easy to clean later.

[0063] Preferably, if Fig.14 As shown, in the step "finishing", an axial bidirectional cutting processing method is adopted, and the axial ends of the honeycomb structure ring are cut in along the axial direction respectively, so that the processing trajectory is connected at the middle position and then cut out along the arc line. In this preferred embodiment, in order to further reduce the generation of burrs, the finishing of the present invention adopts an axial bidirectional cutting processing scheme, that is, during finishing, the two sides are cut in from the axial upper and lower sides respectively, and after the middle position is connected, the arc is cut out, that is, the first knife is cut from the upper side to the middle position and then the arc is cut out, and the second knife is cut from the lower side to the middle position and then the arc is cut out, as shown in FIG. Fig.14 As shown, there is no cutting edge during the finishing process, that is, no burr is generated, and no burr removal work is required later, which greatly reduces the intensity of post-processing work for the staff and shortens the processing cycle.

[0064] Alternatively, if Fig.15As shown, the step of "filling material removal" specifically includes the following steps:

[0065] Drying: Drying the soft material filled in the honeycomb structure sheet 1.

[0066] Blowing material: using compressed air to blow the soft material out of the core cell 101 of the honeycomb structure sheet 1 .

[0067] Cleaning: Use ultrasonic waves to rinse the core grid 101.

[0068] Specifically, since no other adhesive is used when filling the soft material, it is relatively easy to remove the soft material. First, the filling material of the honeycomb structure sheet 1 needs to be fully dried. After the soft material completely loses moisture, it will become soft. Then, compressed air is used to blow the core cell 101 to remove most of the soft material. If the core cell opening 102 of the honeycomb structure sheet 1 is fixed downward by the positioning and fixing device 3 before blowing and the vibrating filling device 2 is used to vibrate, such as Fig.15 As shown, the effect of removing the soft material will be better; after most of the soft material is removed, the core cell opening 102 of the honeycomb structure sheet 1 is placed downward, and ultrasonic cleaning can be performed to completely remove the soft material. The material removal operation is simple, time-saving and labor-saving.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
