Thus, the pre-arched inner roof panel of the present invention may be constructed, inter alia, from continuous glass fiber reinforced thermoplastic honeycomb panels.

According to an embodiment of the present invention, there is provided a pre-arching device, as shown in fig. 1 and 2, including a frame 100 and a lifting mechanism 200. Wherein the housing 100 has a carrier platform 110 for placing the ceiling 10. The lifting mechanism 200 is fixedly disposed on the frame 100, the bottom of the lifting mechanism 200 is provided with a pressing mold 210, the pressing mold 210 is configured to be rod-shaped and extends along the length direction of the stage 110 in a substantially horizontal plane, and the lifting mechanism 200 can drive the pressing mold 210 to move in a vertical direction. As an implementation, the rack 100 may have a plurality of support columns for supporting the carrier platform 110 such that the upper surface of the carrier platform 110 is positioned substantially parallel to a horizontal plane.

It is understood that the length of the pressing mold 210 in the length direction of the carrier platform 110 needs to be greater than the length of the inner top panel 10 to be processed, so that the upper surface of the inner top panel 10 can form a groove penetrating through the inner top panel 10 to ensure that the inner top panel 10 can have a good arching effect.

In addition, a high temperature resistant cloth 220, for example, teflon, may be further disposed on the bottom of the pressing mold 210 facing the stage 110.

In the present embodiment, when the inner ceiling panel 10 is pre-arched using the pre-arching device, a worker may place the inner ceiling panel 10 on the loading platform 110, and thereafter, operate the elevating mechanism 200 such that the pressing mold 210 moves downward in the vertical direction, and the pressing mold 210 contacts and presses the inner ceiling panel 10. The temperature of the pressing mold 210 needs to be raised to a predetermined temperature, and the high temperature of the pressing mold 210 can be conducted to the upper surface of the inner top plate 10 through the high temperature resistant cloth 220, so that the inner top plate 10 is gradually heated from the outside to the inside, and finally reaches the deformation temperature. After the pressing die 210 reaches a preset pressing time, the lifting mechanism 200 controls the pressing die 210 to lift, the inner top plate 10 is naturally cooled, and a uniform and smooth groove is formed on the upper surface of the inner top plate 10, so that the inner top plate 10 can have a good arching effect. It will be appreciated that, after the inner top panel 10 is recessed on the upper surface thereof, the inner top panel 10 is turned over to be fixedly mounted on the cabinet in a later installation, that is, the recessed surface of the inner top panel 10 is vertically downwardly mounted on the cabinet.

According to the utility model discloses a pre-arching device, bottom at press die 210 is provided with high temperature resistant cloth 220, can be so that press die 210 can be heated to compare in the higher temperature of prior art, can be including the upper surface formation darker recess of roof 10, therefore, when guaranteeing that interior roof 10 has enough hunch-up effect, can be including the upper surface formation quantity recess still less of roof 10, can reduce the processing step, reduce the cost of manufacturing, and because the existence of high temperature resistant cloth 220, the material of the upper surface of interior roof 10 after the heating can not adhere to high temperature resistant cloth 220 or press die 210 on, can be so that the upper surface of interior roof 10 can form even smooth recess, its surface quality is better.

For example, in order to provide the roof lining 10 with a sufficient arching effect, the prior art requires heating the mold to 150 ℃, and 3 shallower grooves are formed on the upper surface of the roof lining 10. In the present embodiment, the pressing mold 210 may be heated to 200 ℃, and only 1 deep groove needs to be formed on the upper surface of the ceiling plate 10 to achieve the same effect.

Specifically, the pressing mold 210 includes a pressing housing 211 and a heating member 212. The pressing housing 211 is configured in a rod shape, and the heating member 212 is disposed inside the pressing housing 211 for heating the pressing housing 211. As one implementation, the high temperature-resistant cloth 220 may be completely coated on the outer surface of the pressing housing 211, and the high temperature-resistant cloth 220 may be fixed to the pressing housing 211 using a fastener such as a rivet or a screw.

In addition, in order to timely know the temperature of the pressing mold 210 during operation, the pressing mold 210 in this embodiment further includes a temperature measuring component 213, and the temperature measuring component 213 can at least partially extend into the pressing housing 211 so as to detect the temperature of the pressing housing 211 and the heating component 212. Preferably, the temperature measuring part 213 may use a K-type thermocouple.

Further, the pressing housing 211 in this embodiment may be configured as a square pipe having four corners in a cross section perpendicular to a length direction thereof, one of the corners of the square pipe being configured to face the stage 110. Thus, when the pressing mold 210 presses the inner top plate 10, one of the corners of the square duct can press the inner top plate 10 via the high temperature resistant cloth 220, and the corner and the two sides connected to the corner can form a substantially V-shaped groove on the upper surface of the inner top plate 10. By forming the grooves in such a structure, the inner ceiling panel 10 can be made to arch more easily.

As an implementation manner, as shown in fig. 4, the high temperature resistant cloth 220 may be attached to the top corner of the square pipe facing the loading platform 110 and two side edges connected to the top corner, and then the high temperature resistant cloth 220 is fixed on the pressing housing 211 by using a fastener such as a rivet or a screw.

Correspondingly, in order to facilitate the installation of the square pipe, the bottom of the lifting mechanism 200 in this embodiment is further provided with a fixing seat. Illustratively, as shown in fig. 3, the fixing base may be configured as two L-shaped steels extending along the length direction of the loading platform 110, the two L-shaped steels are disposed opposite to each other, the pressing housing 211 configured as a square pipe is disposed between the two L-shaped steels, the left and right vertex angles of the square pipe are disposed opposite to the L-shaped steels, respectively, and then the L-shaped steels and the square pipe are fixedly connected by screws.

Further, the upper surface of the carrier platform 110 may be configured to be gradually inclined downward from both side edges toward the center in the width direction of the carrier platform 110. This can contribute to the formation of a crowned structure of the ceiling panel 10.

Correspondingly, the pressing mold 210 may be located above the lowest position of the upper surface of the stage 110. Thus, during the pre-arching process of the ceiling board 10, the pressing mold 210 moves downward, and the ceiling board 10 may be bent in the inclined direction of the upper surface of the stage 110 and bent to the lowest point at a position near the center, thereby contributing to the post-arching deformation of the ceiling board 10. As one implementation, a central position of the upper surface of the stage 110 in the width direction thereof is the lowest point, and the pressing mold 210 may be disposed above the central position.

In addition, at least one of two sides of the upper surface of the carrier platform 110 in the width direction of the carrier platform 110 is further provided with a positioning seat for positioning the inner top plate 10. For example, a positioning seat may be disposed on one side edge of the upper surface of the carrier platform 110, and the positioning seat may extend along the length direction of the carrier platform 110. When the inner top plate 10 needs to be pre-arched, the inner top plate 10 can be placed on the loading platform 110, and one side of the inner top plate 10 abuts against the positioning seat, so that the position of the inner top plate 10 in the width direction can be positioned. Preferably, at least one of two sides of the upper surface of the carrier platform 110 along the length direction of the carrier platform 110 may also be provided with a positioning seat for positioning the inner top plate 10, so as to position the position of the inner top plate 10 along the length direction.

The pressing mold 210 needs to press the inner top plate 10 in the length direction of the stage 110, and therefore, the pressing mold 210 needs to have a sufficient length, and therefore, the elevating mechanism 200 needs to have a sufficient number and to be capable of moving synchronously to drive the pressing mold 210 to move in the vertical direction. In the present embodiment, the elevating mechanism 200 configures a cylinder, and the number of the elevating mechanism 200 is at least 2. As shown in fig. 1, the stage 110 in the present embodiment is provided with 5 cylinders.

Further, the pre-arching apparatus in this embodiment further includes a control cabinet 300 disposed on the frame 100, and a temperature controller and a timer electrically connected to the pressing mold 210 are disposed in the control cabinet 300. Wherein the temperature controller can accurately control the temperature, and the timer can record the duration. Illustratively, the temperature controller may be electrically connected to both the heating member 212 and the temperature measuring member 213, and may control the heating member 212 to be heated to 220 ℃ and stop heating when the pressing mold 210 needs to be heated to 200 to 220 ℃ during the pre-arching process of the inner top panel 10, and thereafter, control the heating member 212 to be heated to 220 ℃ again and then stop heating when the temperature measuring member 213 detects that the temperature of the pressing mold 210 is lowered to 200 ℃. By this control, the temperature of the press mold 210 can be maintained within a desired processing range. The timer may record the duration of the pre-arching of the inner top plate 10 by the pressing mold 210, so as to remind a worker or control the lifting mechanism 200 to lift the pressing mold 210 after the duration of the pre-arching is reached, thereby avoiding damaging the inner top plate 10.

In addition, the loading platform 110 may further include a switch for controlling the movement of the lifting mechanism 200, and a direction switching valve for controlling the movement direction of the lifting mechanism 200.
