Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention applies pressure by vertically adjusting the lower roll position in a so-called folded plate shaping machine for corrugated insulation-clad steel plates used for roofs, etc. The present invention relates to a folded plate shaping machine that is changeable and forms the folded plates with the steel plate side facing downward, thereby eliminating the need for reversing the folded plates when cutting and transporting them.

[Prior art] In order to shape a heat insulating material-clad steel plate into a wave shape using upper and lower pressure rolls, conventionally, as shown in Fig. 5, rolls a and b of large diameter and small diameter are arranged on the same axis at equal intervals. Then, by means of the corresponding pressure rolls c, the heat insulating material-clad steel plate S is inserted between each roll with the steel plate surface facing upward, and is shaped into a wave shape, with the pressure rolls facing downward to form the valleys. Adjust the pressure for each pressure roll using screws d, etc.
A molding machine is used that prevents the insulation-clad steel plate from warping, and the downward pressure of the valley molding rolls can be adjusted on the top surface of each roll in this folded plate molding machine. The adjustment work was very easy.

[Problem to be solved by the invention] However, in order to cut easily, accurately and beautifully the insulation-clad steel plate that is the raw material for folded plates, the flexible insulation material is placed on the top surface, and the cutting blade is placed on the upper insulation layer. This was done by first cutting the surface of the material and then cutting the lower steel plate, and the raw material had to be turned over to be fed to the folding plate shaping machine.

In addition, to prevent damage to the soft and easily damaged insulation material when transporting it or lifting it onto the roof for construction, and to make it easier to transport, it is customary to have the steel plate side face down, and therefore, the insulation material is turned over once when supplying the material. Then, it is necessary to turn the mold over again after molding, which requires a wasteful method, and in the case of a large plate, it is difficult to turn over the plate, and a large space is required. Ta.

Therefore, in order to eliminate the need for reversing work, it is sufficient to supply the raw material with the steel plate surface facing downward in advance. However, if the raw material is supplied in this state to a conventional molding machine, the pressure of the lower roll at the peak molding roll will be reduced. is steel plate A
The insulation material B is bent too much at the valley part.
Even if the pressure of the roll that presses the surface side is adjusted, the so-called heat insulating material cannot be crushed and it cannot be sufficiently shaped, so the corners are rounded and the center part of the folded plate is lifted upwards as shown in Figure 6. This is inconvenient because it warps. In order to prevent this problem, it is convenient to adjust the pressure of the crest forming roll of the lower pressure roll that acts on the A side of the steel plate, as shown in FIG. 7, so that the steel sheet is easily formed. Adjustment of the lower pressure roll must be performed from below the machine base, which is difficult, and it would be almost impossible to adjust the roll below the center of the machine base.

[Means for Solving the Problems] The present invention was proposed in view of the above-mentioned situation, and it is possible to form a folded plate with the same quality as before using a folded plate forming machine, with the steel plate surface facing downward. By making this possible, the need for reversing work when supplying raw materials, transporting or handling folded plates is minimized,
In order to save labor, the folded plate forming machine consists of an upper roll and a lower roll that form insulation-clad steel plates into a corrugated shape. and small-diameter roll parts for shaping the ridges alternately and at equal intervals, and the lower roll is a pressure roll corresponding to the large-diameter roll part and the small-diameter roll part, and the ridges of the upper roll The lower rolls corresponding to the small roll parts for forming part molds are respectively supported by respective arms which are pivotally connected at one end, and are fixed to respective shafts parallel to the lower roll axis so as to rotate individually. The present invention provides a folded plate forming machine in which the other end of each of the arms is supported on a possible eccentric cam.

[Example] A folded plate forming machine which is an example of the present invention will be described below with reference to the drawings.

1 is a large diameter roll part, 2 is a small diameter roll part, which are alternately attached to the upper shaft 3 and attached to the collar 4.
A lower shaft 5 is disposed below the upper shaft 3, and a pressure roll 6 attached to the lower shaft 5 corresponds to the large diameter roll portion 1 at a predetermined interval. The shaft 3 and lower shaft 5 are pivotally supported between frames 7 and 7', and gears 8 and 9 fixed to each frame engage with each other to generate a large force. The diameter roll portion 1 and the pressure roll 6 are configured to rotate at the same surface speed.

Reference numeral 10 denotes a pressure roll provided corresponding to the small diameter roll portion 2 of the upper shaft 3. The pressure roll 10 is pivotally supported by individual arms, and one end 11a of each arm 11 is connected between the frames 7. The upper and lower shafts 3 and 5 are pivoted on a beam 12 installed parallel to the shafts 3 and 5, and the other end 11b is supported by an eccentric cam 13.
is supported by.

Also, the first eccentric cam 13 of the eccentric cam 13 is mounted between the bearing 15 placed on the beam 14 installed parallel to the beam 12 between the frames 7 and 7' and the bearing 16 of the frame 7'. The shaft 17 is fixed to a rotatably mounted shaft 17, and a handle 18 is provided at the end of the shaft 17 protruding from the frame 7', and the eccentric cam 13 is configured to be rotatable to a desired angle by the handle 18. .

The second eccentric cam 13' is fixed to the hollow shaft 17 which is slid onto the shaft 17, and a handle 18' is provided at the end located between the frame 7' and the handle 18, and the shaft 17' is connected to the handle. By rotating the eccentric cam 18', the angle of the eccentric cam 13' can be changed separately from the eccentric cam 13.

Similarly, the angle of the third eccentric cam 13'' can be changed by the shaft 17'' and the handle 18''.
There is a bearing that supports 7″.

[Function] The heat insulating material-clad steel plate S inserted between the upper rolls 1 and 2 and the lower pressure rolls 6 and 10 of the folded plate forming machine configured as above is It is held between the large-diameter roll 1 and the pressure roll 6 and sent out, and the troughs are shaped and the roll part 2
The folded plate is completed by shaping the peaks with the pressure roll 10 at the bottom.

At this time, the troughs are shaped by receiving a certain pressure between the large diameter roll part 1 and the pressure roll 6 at a certain position, and the folded plate as a whole tends to warp downward, so the pressure roll 10 By increasing or decreasing the pressure, it is possible to adjust the effect on the surface of the steel plate, which is likely to be shaped, and prevent the folded plate from curving. The pressure of the pressure roll 10 can be adjusted by rotating the handles 18, 18', 18'' by a required angle and rotating the eccentric cams 13, 13'13'', thereby swinging the arm 11 and adjusting the pressure of the pressure roll 10 and the small diameter. This can be done by adjusting the distance from the roll section 2. In addition, there is no need to crawl under the machine base, and it can be easily done from the side of the machine base.

[Effects] Since the folded plate forming machine according to the present invention has the above-described structure and operation, the pressure of the lower pressure roll for forming the mountain part is applied to each roll at the shaft end of the roll, that is, the side surface of the machine base. By supplying a heat insulating material-clad steel plate with the steel plate surface facing downward, a folded plate without warping can be produced in the same manner as in the conventional method.

Therefore, when the insulation material is pasted onto a continuous steel plate using a pasting machine and then cut into pieces of a predetermined size, it is turned over when being fed to the molding machine, and is likely to be damaged during transportation and handling after molding is completed. There is no need for the wasteful work of turning over again to prevent damage to the plate surface of the insulation material, which greatly saves the number of workers, and since there is no turning over work, there is no damage to the periphery of the folded plate.

In addition, since there is no need to turn over the insulation-clad steel plate, it is possible to feed the steel plate and insulation material from the laminating machine to the forming machine in a continuous state. It can be greatly improved and the cost can be reduced.

Furthermore, since the gap between the upper roll part and the lower pressure roll part can be set strictly, it is possible to perform proper molding according to the width and thickness of the folded plate to be formed.
