- the guide groove 15 formed by these cutting members 3 needs to have a groove width of 0.2 mm or more that can insert the thin wire 25 for cutting, a laser or the like or a knife or It is preferable that the width of the rotary blade be in a range corresponding to the width of the guide groove 15.
- a groove width capable of securely inserting the cutting thin wire 25 into the guide groove 15 is formed, and resistance due to resistance when forming the guide groove 15 is formed.
- the thickness of the knife is preferably 0.5 to 2 mm so that the honeycomb structure 10 is not deformed.
- the material of the knife is preferably a material having a large waterproof property, and more preferably, the material having the above-mentioned thickness and maintaining the rigidity of the cutting member.
- the cutting speed is preferably 20 to 15 Omm / sec. If it is less than 20 mm / sec, the cutting efficiency is impaired. If it exceeds 15 mm / sec, the honeycomb structure 10 may be distorted due to the thickness of the partition walls.
- the frame 20 preferably has two or more arms 21, for example, has a U-shape, and has two arms 21.
- One in which a cutting thin wire 25 is stretched can be cited.
- two arms 21 are sufficient, but more arms 21 can be provided.
- the cutting thin wire 25 be made of a material capable of cutting the honeycomb structure and be as small as possible in diameter so that a large radial force is not applied to the honeycomb structure by cutting. .
- a steel material having a diameter of about 0.1 to 0.05 mm is preferable.
- the cutting thin wire 25 is fixedly stretched between the arms 21 of the frame body 20, or each end of the cutting thin wire 25 is connected to the driving unit 24. And moving the cutting thin wire 25 in the stretching direction.
- a rotating member 22 is provided at the tip of each arm 21 of the frame body 20, a thin wire 25 for cutting is provided between the rotating members 22 and a thin wire 25 for cutting is provided. The end is connected to the drive unit 24, and each end of the thin wire for cutting 25 is pulled by the drive unit 24, and the thin wire for cutting 25 stretched between the rotating members 22 is extended. Those that move in the direction are preferred.
- the honeycomb structure can be cut along with the movement of the thin wires for cutting 25 in the extending direction, so that the cutting resistance when cutting the honeycomb structure 10 is reduced, and the cutting is performed. It is possible to prevent deformation of the honeycomb structure 10 due to the above, or deformation of the partition walls such as cell skew and wrinkles. Furthermore, since cutting is always performed using a different portion of the thin wire for cutting 25, it is possible to prevent a new honeycomb structure from being cut at a stained portion at the time of cutting in the previous process. Since the aging of the fine wire 25 can be prevented, the life of the extremely thin wire 25 for cutting can be greatly extended.
- each end of the thin wire for cutting 25 is alternately pulled by the driving unit 24, and the thin wire for cutting 25 stretched between the rotating members 22 is moved back and forth in the extending direction.
- One end of the cutting wire 25 may be pulled by the driving unit 24, and the cutting wire 25 stretched between the rotating members 22 may be moved in one direction in the extending direction. You may exercise only.
- the cutting device moving portion 14 is connected to the cutting device 2, and the honeycomb structure 10 is elongated.
- Elevating member 37 moving up and down in the direction, and rotatably connected to the elevating member 37, and the cutting device 2 is formed by cutting the cutting member 2 in a direction perpendicular to the longitudinal direction Z of the honeycomb structure 10.
- the elevating member 37 is shared with the elevating member 32 of the cradle moving section 5 described above, so that the vertical movement of the cutter 2 in the longitudinal direction of the honeycomb structure is linked with the same movement of the cradle 3. You may let them.
- the control means of the cutter 2 for example, information on the extrusion speed, length, outer diameter, and outer shape in the longitudinal direction of the honeycomb structure 10 is input to the control unit in advance, and the information is input to the control unit.
- the cutter 2 may perform desired operations by driving each member of the cutter moving unit 14 in response to a command from the control unit based on the above. However, it occurs when the elongated honeycomb structure 10 presses the pedestal by the load detector 7 described above. It is preferable that the fluctuation of the load applied to the cradle 3 is detected, and based on the detected information, the lifting member 37 is driven to start the movement of the cutter 2 in the longitudinal direction Z of the honeycomb structure.
- the extrusion speed in the longitudinal direction of the honeycomb structure 10 is detected by the above-described speed detector 6 or the like, and based on the detected information and the information of the time elapsed from the start of the extrusion, the lifting member 37 is detected. It is preferable to control the moving speed and the starting point of the operation of the arm member 34. Further, a detector (not shown) for detecting the distance to the honeycomb structure 10 is provided in the frame body 20, and the cutter 2 performs a desired cutting operation while detecting the distance to the honeycomb structure. It is also possible.
- control unit for controlling the operation of each member of the cutter moving unit 14 based on information from each of the detectors 6, 7 and the like, but it is necessary to provide the control unit.
- the control unit may be provided outside.
- the same control unit can be used together with the cradle moving unit 5 described above.
- the method of manufacturing a honeycomb structure according to the present invention can be performed by using the apparatus.
- the ceramic raw material to be used is not particularly limited, and may be any material applicable to the honeycomb structure, such as cordierite, SiC, and alumina.
- the present invention is not limited to the above-described embodiments, but includes other aspects as long as the features are not impaired. . Industrial Applicability
- a honeycomb structure in which a honeycomb structure having a thin partition or a large outer diameter can be manufactured continuously without causing deformation of the outer shape of the honeycomb structure and the partition.
- An apparatus and a method for continuously manufacturing a honeycomb structure can be provided.
