Description

[Detailed description of the invention] [Industrial application field] This invention is used to heat the surface temperature of a heated body such as a high-temperature slab in continuous casting by attaching a thermocouple temperature-sensing part to a riveting gun. This invention relates to a thermocouple attachment body that is attached to the surface of a temperature-measuring object using a construction method.

[Prior art] When continuously measuring the surface temperature of a high-temperature slab using a thermocouple, it is common practice to attach and fix the temperature-sensing part of the thermocouple to the surface of the slab with metal rivets. When the paired temperature-sensing portion and the metal stud are integrated, there is a problem in that the temperature-sensing portion of the thermocouple is damaged or its function deteriorates due to mechanical impact when driving the metal stud.

In order to solve this problem, JP-A-58-
Publication No. 96228 has been proposed. In this proposed method, a metal piece to which a thermocouple is connected is fixed to the slab by driving a metal stud of an arbitrary shape into the slab surface that loosely fits into the metal piece, and continuously measures the temperature. .

On the other hand, the tip jig for a riveting gun, which attaches thermocouples to the surface of a continuous cast piece using the riveting gun method, has already been developed since 1983.
This is proposed by Publication No. 22250.

[Problem to be solved by the invention] The above-mentioned Japanese Patent Application Laid-Open No. 58-96228 does not disclose anything about the connection between the metal rivets and the thermocouple temperature-sensing part, which is necessary when driving the metal rivets by the rivet gun method. It has not been.

On the other hand, Japanese Utility Model Application Publication No. 61-22250 discloses a connection between a metal stud and a temperature measuring contact (thermocouple temperature sensing part), but the two are fixed connections, and as mentioned above, the connection is made with a metal stud. Due to the large impact when driving metal rivets using the gun method, it is inevitable that the thermocouple's temperature-sensing part will be damaged, its functionality will deteriorate, or the sheath wire will break.

Therefore, the purpose of this invention is to eliminate the risk of damage to the thermocouple temperature-sensing part, deterioration of its function, or breakage of the sheath wire even if there is a large impact when driving rivets using the rivet gun method, and to prevent the thermocouple temperature-sensing part from breaking. It is an object of the present invention to provide a thermocouple mounting body using a riveting gun method, in which a metal stud having two parts connected thereto can be stably and reliably supported in a gun cavity, and furthermore, it is easy to assemble and manufacture.

[Means for Solving the Problems] The present invention involves attaching a cylinder having a stopper at the tip to the point side of a rivet fired by the rivet gun method, and forming a cylinder between the head of the rivet and the stopper. A riveting device comprising: a ring body for supporting a rivet in the gun cavity is attached to the shaft portion of the gun; and a thermocouple temperature-sensing portion connected to a sheath wire is loosely fitted to the shaft portion between the stopper and the ring body. This is a thermocouple mounting body using the gun method.

[Example] Hereinafter, specific examples will be described in detail based on the drawings.

Figure 1 is a side view (showing the riveting gun in cross section), Figure 2
The figure is a front view, and FIG. 3 is a side view showing the state after implantation.

Reference numeral 1 is the barrel of the riveting gun, 2 is the gun cavity, and 3 is the piston rod that is operated by the combustion energy of gunpowder. 4 is a metal stud, which has a head 5 at the rear end and has a pointed tip. Reference numeral 6 denotes a cylinder attached to the tip side of the metal stud 4, and has a flange-like stopper 7 at the tip.

Reference numeral 8 denotes a ring body made of, for example, Teflon, which is fitted onto the outer periphery of the shaft at an arbitrary position between the head 5 and the stopper 7, the outer periphery of which is in contact with the inner surface of the gun cavity, and the metal stud 4
is stably supported within the gun cavity 2. Reference numeral 9 denotes a thermocouple temperature-sensing section, which has a hole 10 slightly larger than the outer diameter of the cylinder 6, and this thermocouple temperature-sensing section 9 is loosely fitted onto the shaft between the ring body 8 and the stopper 7.

In the figure, 11 is a sheath wire connected to the thermocouple temperature-sensing section 9, and 12 is a temperature-measuring object such as a high-temperature cast piece.

The structure of the embodiment of this invention is as described above, and as shown in FIG.

When the stopper 7 is brought into contact with the surface of the object to be measured 12 in the set state as shown in FIG. 1, and the piston rod 3 is immediately activated to drive the metal stud 4 with a strong impact force, as shown in FIG. The thin-walled cylinder 6 compresses and expands 6' (partly breaking), the Teflon ring 8 breaks and falls off the shaft, and the metal stud 4 penetrates the temperature-measuring object 12 to a sufficient depth. The temperature sensing part 9 of the thermocouple can be firmly attached to the surface of the object 12 to be measured.

The measurement of the surface temperature of the temperature-measuring object 12 is carried out using the temperature-measuring object 1.
2 is instantly transmitted from the metal stud 4 and the stopper 7 to the thermocouple temperature sensing part 9, and the sheath wire 11
The temperature is measured through the

In this case, when the object to be measured is a high-temperature slab manufactured by continuous casting, the one shown in Fig. 3 is pressed against the surface of the slab by the pinch rolls that support and pull out the slab. However, even better contact conditions can be obtained.

The structure of this invention is as described above, and the following effects can be obtained.

(1) Since the ring body 7 made of Teflon or the like is provided on the shaft, the outer peripheral surface of the ring body 7 contacts the inner surface of the gun cavity 2, and the metal stud 4 is stably supported within the gun cavity 2.
The mounting body of this invention will not fall out of the gun cavity 2. Note that the ring body 7 is broken by the strong impact force of the head 5 during riveting, and falls off from the shaft.

(2) The shaft part that supports the thermocouple temperature-sensing part 9 attached to the tip of the metal stud 4 (DIN1722C67) is a thin-walled cylinder 6 (SS41), so the head 5 is protected from strong impact when driving the nail. As shown in Figure 3, the force compresses and expands 6' and its length becomes significantly shorter.
The metal studs 4 can be driven into the temperature-measuring object 12 to a sufficient depth, and the supporting force of the thermocouple temperature-sensing section 9 against the temperature-measuring object 12 is extremely large.

Furthermore, due to the cushioning action of the compression-expanding body 6', the impact force exerted on the thermocouple temperature-sensing section 9 by the metal stud head 5 is alleviated, and as a result, damage to the thermocouple temperature-sensing section 9 and functional deterioration can be effectively prevented. .

Furthermore, since this compression-expansion section 6' elastically transmits the forward force of the head 5 due to driving of the metal rivet to the thermocouple temperature-sensing section 9, there is some variation in the driving depth of the metal rivet 4. However, the thermocouple temperature-sensing section 9 can be firmly attached to the temperature-measuring object 12.

(3) Since the stopper 7 is provided at the tip of the cylinder 6,
The thermocouple temperature sensing portion 9 can be prevented from falling off from the tip of the cylinder 6.

(4) Connect the thermocouple temperature sensing part 9 and the metal stud 4 by attaching the temperature sensing part 9 to the cylindrical part 6 attached to the tip end of the metal stud 4.
Since it is in a loosely fitted state, the impact effect at the time of riveting is less likely to be transmitted to the temperature sensing part 9.
Therefore, there is no risk of damage to the temperature sensing section 9, functional deterioration, or breakage of the sheath wire.

[Effects of the invention] According to this invention, the thermocouple sensor can be sensed using a riveting gun method that is both easy to work with and safe, without damaging the thermocouple temperature-sensing part or degrading its function, and without causing the sheath wire to break. The heating part can be attached to the surface of the object to be measured, and the mounting body can be reliably supported within the gun cavity of the riveting gun.
This greatly contributed to the measurement of the surface temperature of high-temperature objects.
