Temperature measuring equipment

The present invention relates to a temperature measuring device, and more particularly to a temperature measuring device for attaching a thermocouple wire to a plate by fixing a wire position of a thermocouple wire by a fastener and a strap.

One or more heat treatment processes are often carried out in metal processes. Appropriate heat treatment can increase or decrease the properties of the metal depending on the needs of the user. For example, hardness, toughness or strength, and the like.

In general, heat treatment is performed by heating the metal to a certain temperature and then applying a cooling means. The temperature and time of heating, as well as the cooling means, will vary depending on the metal or the desire to enhance different characteristics. In other words, whether the effect on the metal during the heat treatment is good or not, and whether or not the temperature at which the metal itself is actually heated can be confirmed is one of the important factors.

In other words, in the general industrial process, it will be mass-produced as much as possible based on the equipment owned by the site. However, for example, when performing the heating and cooling steps of a bulk plate, it is easy to encounter the problem of uneven temperature of the sheet. For example, in order to save the processing cost of the heat treatment, the sheet material is subjected to a heat treatment such as solution heat in a batch manner (hereinafter referred to as a batch) to uniformize the properties of the sheet as a whole. However, when such a large amount of sheet material is placed in a heating furnace for heating, it is actually difficult to predict the actual temperature of the sheet. Because, although most of the heating furnace will have a thermometer to refer to the temperature inside the heating furnace, but in practical applications, the temperature of each plate is not the same, more or less will be different because of the position placed in the furnace. Therefore, it is impossible to estimate the accuracy of the temperature of the sheet, and in the end it can only be judged according to the rule of thumb.

In order to solve the problem that the temperature at which the metal is actually heated cannot be accurately predicted. For example, the Chinese Patent Application No. 201110388020 discloses a temperature line measuring device for a plate-type quenching process, characterized in that the temperature line measuring device Including temperature measuring steel plate, connecting rod, auxiliary steel plate, multiple thermocouples and temperature recorder; auxiliary steel plate and temperature measuring steel plate are connected to each other by welding connecting rod; thermocouple passes through wire and temperature placed on connecting rod and auxiliary steel plate The recorder is connected; a plurality of temperature measuring holes are processed around the temperature measuring steel plate, and the temperature measuring ends of the plurality of thermocouples are respectively inserted into the plurality of temperature measuring holes; and the temperature recorder is placed in the sealed iron box and fixed on the auxiliary steel plate End.

However, the above-mentioned temperature line measuring device cannot be applied to certain batch types. Heat treatment. For example, on a vertical crane, the spacing between the panels is small, so it is not possible to provide an iron box on the panel. In addition, in order to quickly carry out the cooling step after heating, the cooling pool is arranged under the heating furnace. After the heating of the sheet is completed, the furnace cover under the heating furnace is directly opened, and the chain is released by the motor to move the lifting frame downward. And directly into the cooling pool for the cooling step. However, when the cooling step is performed, the thermal stress of the sheet material is uneven during cooling, and the iron box is easily deformed.

Therefore, it is necessary to provide a temperature measuring device to solve the problems of the conventional technology.

In order to make the above and other purposes, features and advantages of this creation more obvious, DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Furthermore, the directional terms mentioned in this creation, such as upper, lower, top, bottom, front, rear, left, right, inner, outer, side, surrounding, central, horizontal, horizontal, vertical, vertical, axial, Radial, uppermost or lowermost, etc., only refer to the direction of the additional schema. Therefore, the directional terminology used is used to describe and understand the creation, and is not intended to limit the creation.

Please refer to FIG. 1A and FIG. 1B together, and FIGS. 1A and 1B are based on the present creation. The embodiment shows a schematic diagram of the use of a temperature measuring device 100 disposed on a first side 900A and a second side 900B of a sheet 900. The temperature measuring device 100 includes a plurality of thermocouple wires 110, a plurality of fasteners 120, a temperature recording device 130, and a plurality of binding bands 140. In an embodiment, the temperature measuring device 100 can be applied to the sheet material 900 to be subjected to a heat treatment process. The heat treatment process can include, for example, but is not limited to, heating, cooling, or a combination thereof, which can alter the process of phase composition of the metal or alloy. In another embodiment, the sheet material 900 may be an aluminum sheet material or an aluminum alloy sheet material, wherein the aluminum material may be commercially available or may be self-melted according to the use requirements.

The thermocouple wire 110 includes a head end 110A and a tail end 110B. The head end 110A is inserted in the sheet material 900. In one embodiment, the head end 110A is only buried at a position half the depth of the plate.

In one embodiment, the first side 900A and the second side 900B are located on opposite sides of the sheet 900, and the first side 900A and the second side 900B are the two sides of the largest area of the sheet 900. The plurality of fasteners 120, for example, may be a plurality of nuts disposed at a second side 900B relative to the sheet 900 and corresponding to the routing of the thermocouple wires 110.

Furthermore, the temperature recording device 130 of the present invention is connected to the tail end 110B of the thermocouple wire 110 for recording the temperature of the sheet material 900 measured by each thermocouple wire 110. In an embodiment, the temperature recording device 130 can immediately revert the temperature of the sheet 900 measured by each thermocouple wire 110 to a graph of temperature change with time, so that the user can immediately determine whether the furnace needs to be adjusted. temperature setting.

In addition, the present strap bundle 140 passes through the sheet material 900 and binds the thermocouple wires 110 and the fasteners 120 to substantially attach the thermocouple wires 110 positioned between each two adjacent strap bundles 140. The first side 900A of the sheet 900. In an embodiment, the strap 140 can be an iron wire. In another embodiment, the strap 140 can be selected from other high temperature resistant bendable materials. On the one hand, the degree of high temperature resistance is preferably such that the melting point of the binding band 140 is higher than the heat treatment temperature by more than 100 degrees Celsius to prevent the material of the plate 900 from being contaminated by the binding band 140; on the other hand, the bendable material is convenient to use. The thermocouple wire 110 is directly tied where needed.

In one embodiment, the sheet 900 has a plurality of holes 910 and the holes 910 are From the first side 900A to the second side 900B, and the straps 140 pass through the holes 910, respectively. In still another embodiment, the size (aperture) of the holes 910 is smaller than the size (outer diameter) of the fastener 120 (such as a nut), so the fastener 120 cannot pass through the hole 910, and the card is tied by the binding band 140. The firmware 120, so the thermocouple wire 110 is subject to the function of the fastener 120 and the binding band 140, and the first side 900A of the sheet 900 is attached tightly. In another embodiment, the number of thermocouple wires 110 is the same as the number of fasteners 120.

In general, the location of the holes 910 will be the same as the temperature of the sheet 900 to be measured. The location is relevant. As shown in FIG. 1A, holes 910 are provided on the plate 900 in a matrix of 3 x 3, a total of nine. In other words, the temperature measurement can be performed on the circumference and the center of the plate 900 through the thermocouple wire 110. After referring to the nine temperature measurement points, the temperature distribution of the plate 900 can be more accurately determined. On the other hand, in order to make the thermocouple wire 110 substantially adhere to the first side surface 900A of the plate material 900, it is conceivable that the position where the hole 910 is disposed is also related to the wire position of the thermocouple wire 110, so When the position of the hole 910 is also taken, the position of the wire of the thermocouple wire 110 must also be considered.

Please refer to FIG. 2 , which illustrates a temperature measurement device according to an embodiment of the present invention. A schematic diagram of a device 100 mounted on a lifting frame 970 between a immersion quenching cooling bath 990 and a heating furnace 980. In order to avoid the line in the drawing being too complicated, the thermocouple wire 110 is only shown on the leftmost plate 900 of 23, and the fastener and the tie band are not shown. In fact, each sheet 900 is provided with a temperature measuring device 100. In the heat treatment, the position of the lifting frame 970 may be adjusted such that the lifting frame 970, together with the sheet material 900 thereon, is moved upward into the heating furnace 980 located above, so that the sheet material 900 can be subjected to a heat treatment such as solution heat treatment. At this time, the temperature recording device 130 can record and instantly remit the temperature to the computer screen to facilitate the user to determine the actual temperature of the sheet 900. Thereafter, after heating and holding the temperature for a predetermined period of time, the position of the lifting frame 970 is adjusted so that the lifting frame 970, together with the sheet material 900 thereon, enters the lower immersion quenching cooling tank 990 for quenching. Cooling treatment. This shows that this creation The temperature measuring device 100 does not need to be additionally provided in the iron box of the measuring device on the temperature line as described above, so even if the lifting frame 970 is used for batch heat treatment, the actual temperature of the plate 900 can be accurately measured. On the other hand, since the thermocouple wire 110 is mainly disposed on the plate member 900 by the pay-off method, there is no fear that the uneven thermal stress of the plate member 900 at the time of performing the cooling step may affect the temperature measuring device 100.

As described above, the temperature measuring devices of the various embodiments of the present invention are mainly transmitted through The bundle brings the thermocouple wire substantially attached to the first side of the sheet to prevent the thermocouple wire from being hooked and broken, and the temperature of the sheet cannot be measured. On the other hand, through the holes in the plate, so that the wiring pattern of the thermocouple wire can be configured according to the site environment, it can adapt to various environmental changes in the field.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application.
