Description

The honeycomb core is made by applying glue to a number of honeycomb tubes, stacking and pressing them, and then drying and curing them.

[0003] The honeycomb tube needs to be melted and extruded during production. The existing extruder is composed of a supporting transmission device, a spiral extrusion barrel, a feeding barrel, a heating system, an extrusion die head, etc. It can automatically complete the extrusion of the honeycomb tube.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] Embodiment 1

[0053] like Figure 1-7 As shown, a high-precision and high-speed honeycomb core extruder proposed in the present application includes a machine base 1 and a feed barrel 2 installed at the upper end thereof, the side wall of the feed barrel 2 is provided with a heating system 4 for heating and melting the material (this is the processing method of the prior art, and the specific principle is not repeated here), a motor for driving the internal screw of the feed barrel 2 to rotate is installed on one side of the machine base 1, a feed box 3 is provided at the upper end of the feed barrel 2, and a feed pipe is connected to the upper end of the feed box 3, and the output end of the feed barrel 2 is connected to the extrusion die 9 through the output base 5, and the side wall of the extrusion die 9 is provided with a mold correction ring 11, and a plurality of mold correction bolts 12 are connected to the side wall of the mold correction ring 11 at different angles, and the distance between each mold correction bolt 12 and the axis of the mold correction ring 11 is adjusted, thereby adjusting the degree to which the axis of the extrusion die 9 deviates from the axis of the mold correction ring 11 (this is the existing adjustment method, and the specific structure and principle are not repeated here). The output base 5 and the extrusion die 9 are fixed by a plurality of connecting bolts 17, and the plurality of connecting bolts 17 complete the axial fixation of the output base 5 and the extrusion die 9 at multiple angles. The output base 5 and the extrusion die 9 are provided with a plurality of corresponding sets of thread grooves 16 in the axial direction, and the plurality of connecting bolts 17 are respectively threadedly inserted into the plurality of corresponding sets of thread grooves 16. A polygonal groove 18 is provided in the central axial direction of the connecting bolt 17. A magnetic block A is embedded in the inner wall of the polygonal groove 18, and a polygonal column 15 that attracts the magnetic block A is inserted in the polygonal groove 18.

[0054] It also includes a tightening operating member 7 sleeved on the outside of the extrusion die head 9, which is used to synchronously rotate and advance a plurality of connecting bolts 17, so that the tightening of the plurality of connecting bolts 17 can be completed in one step, which is easy to operate and improves the installation efficiency of the extrusion die head 9.

[0055] Specifically, the fastening operating member 7 includes a sleeve 71 threadedly sleeved on the side wall of the extrusion die head 9, the inner wall of the sleeve 71 is fixedly connected to an outer ring 72, the inner wall of the outer ring 72 is rotatably connected to a support ring 73, the inner ring of the support ring 73 is rotatably connected to an inner ring 74, the inner diameter of the inner ring 74 is the same as the inner diameter of the extrusion die head 9, the inner wall of the outer ring 72 is fixedly connected to a transmission ring 76, and a propulsion rotation assembly 75 is provided between the transmission ring 76 and the support ring 73. When the sleeve 71 is rotated, the propulsion rotation assembly 75 can be driven. It is sleeved on the outer wall of the extrusion die head 9, but the interval of the threaded connection is smaller than the depth of the insertion of the connecting bolts 17. Therefore, when the sleeve 71 is rotated in the initial stage, the sleeve 71 is slowly pushed toward the extrusion die head 9. When the internal thread at the inner end of the sleeve 71 overlaps with the external thread on the extrusion die head 9, the sleeve 71 can automatically move toward the direction of the extrusion die head 9 when the sleeve 71 is rotated. When the sleeve 71 is completely threaded on the outer wall of the extrusion die head 9, several connecting bolts 17 are respectively screwed into several groups of thread grooves 16 to complete the axial fixation of the extrusion die head 9 and the output base 5.

[0056] Furthermore, the propulsion rotation assembly 75 includes a gear ring 751 fixedly connected to the inner wall of the transmission ring 76, and the inner surface of the support ring 73 is rotatably connected to a plurality of sleeves 752, and the side wall of the sleeve 752 is fixedly sleeved with a gear 753 that meshes with the gear ring 751; when the sleeve 71 is rotated, the gear ring 751 meshes with the plurality of gears 753, thereby driving the sleeve 752 to rotate. A magnetic block B14 is embedded in the inner wall of the sleeve 752, and the other end of the polygonal column 15 is inserted into the sleeve 752 and attracts the magnetic block B14 (the groove on the side of the sleeve 752 is a polygonal groove). After the extrusion die head 9 is docked at one end of the output base 5, a plurality of polygonal columns 15 are respectively inserted into a plurality of sleeves 752. The polygonal columns 15 are made of iron. Since a magnetic block B14 is arranged in the sleeve 752, the polygonal columns 15 can be fixed, so that the polygonal columns 15 are stably inserted in the sleeve 752, and the insertion depth of each polygonal column 15 is ensured to be the same. Then, the connecting bolt 17 with a polygonal groove 18 is sleeved on the outside of the polygonal column 15. Since a magnetic block A is arranged on the inner wall of the polygonal groove 18, the connecting bolt 17 is stably sleeved on the outside of the polygonal column 15, and the sleeve state of each connecting bolt 17 is ensured to be the same.

[0057] Furthermore, a guide member 10 is provided between the output base 5 and the extrusion die head 9; the guide member 10 includes a guide groove 101 provided on the extrusion die head 9, and one end of the output base 5 is fixedly connected with a guide column 102 inserted into the guide groove 101. The guide member 10 is provided in two groups, and when the extrusion die head 9 is docked at one end of the output base 5, the two guide columns 102 are respectively aligned with the two guide grooves 101 and inserted into the two guide grooves 101, and then the extrusion die head 9 is pushed tightly against the end of the output base 5, thereby playing a guiding role, so that the output base 5 can be aligned with the thread groove 16 on the extrusion die head 9, which is convenient for the next step of fixing operation.

[0058] The working principle of this embodiment is as follows: after the extrusion die head 9 is fitted and docked at one end of the output base 5, the worker holds the sleeve 71 to align the plurality of connecting bolts 17 with the plurality of thread grooves 16 respectively (because one end of the connecting bolt 17 extends out of one end of the sleeve 71 before being fixed, it is convenient for the worker to observe and align the plurality of connecting bolts 17 with the plurality of thread grooves 16 respectively). In the next step, the sleeve 71 is rotated and the sleeve 71 is slowly pushed at the same time. Because the plurality of connecting bolts 17 have been inserted into the plurality of groups of thread grooves 16 before the sleeve 71 is rotated, the support ring 73 is radially positioned at this time, and the support ring 73 will not rotate radially (so that the plurality of connecting bolts 17 are pushed in the same axial direction). The rotating sleeve 71 drives the outer ring 72 to rotate, and the rotation of the outer ring 72 drives the transmission ring 76 to rotate, thereby driving the gear ring 751 to rotate, so that the gear ring 751 is meshed with the plurality of gears 753 for transmission, so that the plurality of connecting bolts 17 are synchronously advanced while rotating, and the threads are rotated into the thread grooves 16. When the inner end of the sleeve 71 is completely threadedly connected to the extrusion die head 9, the plurality of connecting bolts 17 are respectively threadedly inserted into the plurality of sets of thread grooves 16. The extrusion die head 9 and the output base 5 are fixed synchronously and quickly, and the fixing tightness of each angle is ensured to be the same, which saves the time of die installation and reduces the difficulty of die installation.

[0059] Embodiment 2

[0060] The high-precision and high-speed honeycomb core extruder proposed by the present invention is as follows: Figure 2-7 As shown, this embodiment also includes: a shell 6 is sleeved on the outer side of the output base 5, a fixed mold mechanism 13 is provided on the shell 6 for positioning a plurality of mold adjustment bolts 12, and a spiral member 8 for triggering the fixed mold mechanism 13 is provided on the sleeve 71.

[0061] Specifically, the spiral member 8 comprises an annular groove 81 formed on the outer wall of the sleeve 71, and a spiral ring 82 is threadedly sleeved in the annular groove 81. Before the adjustment of the plurality of calibration bolts 12 is completed, the spiral ring 82 is fitted with the sleeve 71.

[0062] Furthermore, the fixed mold mechanism 13 includes a pneumatic cavity 131 opened inside both sides of the shell 6, one side of the two pneumatic cavities 131 passes through to the outside of the shell 6, a pneumatic cavity 133 is opened inside the upper end of the shell 6, one side of the pneumatic cavity 133 passes through to the outside of the shell 6, and the pneumatic cavity 133 is connected to the pneumatic cavity 131 through a connecting cavity 132; a pneumatic part 135 is commonly provided in the two pneumatic cavities 131, and the pneumatic part 135 is used to position a plurality of mold correction bolts 12.

[0063] The second pneumatic cavity 133 is provided with a triggering member 134 for driving a pneumatic member 135 .

[0064] Specifically, the pneumatic part 135 includes a piston disc 1351 pneumatically arranged in two pneumatic cavities 131, and the inner walls at both ends of the pneumatic cavity 131 are embedded with a limiting ring for limiting the piston disc 1351 to prevent the piston disc 1351 from being separated from the pneumatic cavity 131 under the action of air pressure or external force. One end of the two piston discs 1351 is fixedly connected to a connecting rod 1352 extending to the outside of the housing 6, and the outer ends of the two connecting rods 1352 are commonly fixedly connected to a transmission ring 1353, and the transmission ring 1353 is connected to a surface close to the mold calibration bolt 12 with a plurality of arc-shaped positioning buckles 1354; the inner diameter of the arc-shaped positioning buckle 1354 is adapted to the outer diameter of the mold calibration bolt 12, and the inner arc surface of the arc-shaped positioning buckle 1354 is embedded with an anti-slip pad. A notch is provided at the upper end of the transmission ring 1353.

[0065] The trigger member 134 includes a piston plate 1341 slidably disposed in the pneumatic chamber 133, the outer surface of the piston plate 1341 is fixedly connected to a U-shaped connecting rod 1342, and the outer surface of the U-shaped connecting rod 1342 is rotatably connected to a pair of transmission rods 1343. It is worth noting that the transmission rod 1343 and the partial cross section of the spiral ring 82 are located in the same horizontal plane, and when the spiral ring 82 is rotated, the two transmission rods 1343 can be pushed to one side. Since the two transmission rods 1343 are rotatably connected to the U-shaped connecting rod 1342, the spiral ring 82 reduces the resistance generated by the rotational pushing method when pushing the transmission rod 1343. When the pneumatic member 135 positions the mold proofing bolt 12, the spiral ring 82 conflicts with the transmission rod 1343.

[0066] The working principle of this embodiment is as follows: when each calibration bolt 12 is adjusted, the spiral ring 82 is rotated. Since the spiral ring 82 is threadedly connected in the annular groove 81, rotating the spiral ring 82 in the positive and negative directions will make the spiral ring 82 move closer to or away from the housing 6. At this time, the spiral ring 82 is rotated forward to move the spiral ring 82 closer to the housing 6. When the spiral ring 82 moves closer to the housing 6, it squeezes and pushes the two transmission rods 1343, and the U-shaped connecting rod 1342 is pushed to move by the two transmission rods 1343, thereby making the piston plate 1341 slide in the pneumatic chamber 133, and the gas inside the pneumatic chamber 133 passes through the two transmission rods 1343. The connecting cavity 132 is squeezed into the two pneumatic cavities 131, and finally the two piston discs 1351 are pushed to move under the action of air pressure, so that the two connecting rods 1352 move toward the outside of the shell 6, and then the transmission ring 1353 moves close to the plurality of mold proofing bolts 12, and the plurality of arc-shaped positioning buckles 1354 are clamped on the side walls of the plurality of mold proofing bolts 12, and radially abut against the plurality of mold proofing bolts 12, so as to position the adjusted mold proofing bolts 12, and prevent the mold proofing bolts 12 from loosening or over-tightening under the influence of subsequent working vibration or other factors of the extruder, and further improve the accuracy of honeycomb tube extrusion. Since one end of the spiral ring 82 abuts against the two transmission rods 1343, it limits the pull-back direction of the two transmission rods 1343, and then limits the arc-shaped positioning buckle 1354, so as to prevent the arc-shaped positioning buckle 1354 from being away from the mold proofing bolts 12 and being positioned loose (during the operation of the extruder).

[0067] The above-mentioned specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
