Description

  The present invention relates to a heating apparatus and a heating method for sandwiching and heating an object to be heated between temperature-controlled hot plates.

  As shown in FIG. 4, the conventional heating apparatus heats an object to be heated 110 by sandwiching it between a pair of hot plates 101a and 101b. Each pair of hot plates 101a and 101b is supported by an LM guide 102 so as to be openable and closable, and is configured to be opened and closed for each pair by a hot plate opening and closing mechanism 105 such as an air cylinder.

  While this heating method can control the temperature with high accuracy, two heating plates with a temperature control function are required for one object to be heated. The cost was high.

  Further, for example, a multistage heating type heat treatment apparatus disclosed in Patent Document 1 is also known. This is a method in which a plurality of hot plates are arranged at a set interval, and an object to be heated is placed between the hot plates and heated, but there is little freedom in the hot plate interval, and the hot plate is a radiant heating plate. Therefore, the thermal efficiency was worse than when the object to be heated was sandwiched and heated.

In the press field, as disclosed in Patent Document 2, a multi-stage press hot plate is known, but it is configured to operate a plurality of hot plates at the same time, and when the hot plate is opened, all the hot plates are opened. It was not possible to open only between any hot plates.

  The present invention has been made in view of the above-mentioned unsolved problems of the prior art, and can open only between any hot plates, and has a compact structure and low cost. An object is to provide an apparatus and a heating method.

The heating device of the present invention is a heating device that heats an object to be heated between a plurality of temperature-controlled hot plates, a reference support means for supporting the first hot plate at a reference position, and a plurality of second heats. Movable support means for supporting the plate in a reciprocating manner independently in the same opening and closing direction toward the first hot plate, and a second hot plate farthest from the first hot plate in the opening and closing direction A hot plate opening / closing mechanism for widening the gap between the hot plates is provided with an air chuck on the uniaxial linear motion mechanism from the back side of the heating device. It is characterized in that it can be freely opened and closed independently between each other by opening and closing with an installed auto hand .

  By efficiently using both sides of the temperature-controlled hot plate, the number of hot plates can be greatly reduced, and a small space and low cost can be realized.

  Also, the number of driving means such as air cylinders for opening and closing the hot plate can be reduced.

  Furthermore, by reducing the number of heat plates, it is possible to realize low cost by reducing the number of temperature controllers and heaters.

  Since each hot plate can be moved independently, the degree of freedom of the hot plate interval is large, and it can correspond to a wide range of heated objects.

  The best mode for carrying out the present invention will be described with reference to the drawings.

  As shown in FIG. 1 and FIG. 2, in a heating apparatus that heats an object to be heated 10 by sandwiching each heated plate by opening and closing the gaps between a plurality of temperature-controlled hot plates 1 (1 a to 1 i). The hot plate 1a disposed at one end is used as a reference hot plate (first hot plate). The remaining hot plates (second hot plates) 1b to 1i are sequentially moved toward the reference hot plate in the direction in which the heated object 10 is sandwiched (opening / closing direction), so that the heated object is placed between the hot plates. 10 is sandwiched and heated.

  The remaining hot plates 1b to 1i excluding the hot plate 1a are movable hot plates supported by the LM guide (movable support means) 2 so as to be independently movable (see FIG. 3). Each of the hot plates 1a to 1i is heated and temperature-controlled by the heater 3. Here, the support of the hot plates 1b to 1i is not limited to the LM guide 2, and a combination of a shaft and a linear bush can be used.

  At least three or more of the hot plates 1 are combined (9 in the figure), and the hot plate 1a at one end is fixed to a reference position by a fixing block (reference support means) 4 as a reference hot plate, and the hot plate 1i at the other end. Is connected to the driving means 5.

  The reference hot plate does not necessarily need to be fixed, and may be moved depending on the situation of use.

  When the object to be heated 10 is heated, the object to be heated 10 is thrown in by expanding the hot plate gap at an arbitrary position by the hot plate opening / closing mechanism (second driving means) 11 disposed on the back surface of the heating device. Since the size of the heated object 10 that can be input is determined by the opening / closing stroke width of the hot plate opening / closing mechanism 11, the larger the opening / closing stroke width, the wider the specification range. However, if the opening / closing stroke width is made too large, the equipment becomes enormous, so it is necessary to select appropriately depending on the size of the object to be heated 10.

  Thereafter, the driving means 5 is driven to sequentially move the hot plates 1b to 1i to the reference hot plate side, so that the object to be heated 10 is sandwiched and heated between the hot plates 1a to 1i.

  In the configuration shown in FIGS. 1 to 3, a heating device having a flat plate-like hot plate and a total of six hot plates was manufactured. One of the hot plates was fixed by a fixed block to be a reference hot plate, and the remaining five hot plates were attached to an LM guide to be a movable hot plate that was slidable. The size of each hot plate was W180 mm × H370 mm × T20 mm, and the material was aluminum A2017. A cartridge heater was inserted into each hot plate to make the heat capacity 900 W. An air cylinder was used as a driving means for opening and closing the movable hot plate, and it was arranged at the end opposite to the reference hot plate. The hot plate opening / closing mechanism for widening the hot plate gap was opened / closed from the back side of the heating device by an automatic hand in which an air chuck was installed in a uniaxial linear motion mechanism.

  The object to be heated was heated by the heating device having the above-described configuration. The object to be heated was a rectangular parallelepiped of W150 mm × H400 mm × T34 mm (partially uneven), and the material was aluminum A2017 (partially different material).

  Compared to the case where the heat treatment is performed using the conventional heating apparatus shown in FIG. 4, this embodiment reduces the number of hot plates by 40%, the temperature controller by 40%, and the total space by 67%. We were able to.

  In addition, in the configuration in which a plurality of hot plates are opened and closed simultaneously, there is a lot of wasted hot plates, and when the hot plates are opened, all the hot plates are in the open state, so there is wasted space to widen the space between unnecessary parts. However, in this embodiment, it was possible to greatly reduce the total space.

It is a perspective view which shows the heating apparatus by one embodiment. It is a perspective view of the back surface side of the apparatus of FIG. It is a perspective view which shows the structure of the hot platen of the apparatus of FIG. It is a perspective view which shows the heating apparatus by a prior art example.
