に強制的に折曲げ加工するものである。 This is made up of a lower wave type formed by connecting in parallel a plurality of lower wave type units whose upper surfaces are formed into a wave shape, and a plurality of upper wave type units whose lower surfaces are formed into a wave shape and connected in parallel. By sandwiching a long plate material formed into a substantially corrugated shape between the upper corrugated mold and bending the lower corrugated mold and the upper corrugated mold using a hydraulic cylinder, the plate material sandwiched between both corrugated molds can be bent. This process is forcibly bent in a direction perpendicular to the continuous direction of the waveform.

い。 When bending a plate material using the bending device configured as described above, after placing a long plate material on the lower corrugated mold, a worker manually rotates the upper corrugated mold unit one by one. After placing and fixing the plate on the plate and bending the plate, in order to take out the plate from the device, the upper part of the corrugated unit must be reversed and removed one by one to open the upper part of the plate.

りする作業は重労働となつていた。 In this way, when bending at a time, it is necessary to manually rotate and fix several heavy metal upper corrugated units to the lower corrugated unit, and then turn them over and remove them. becomes. In particular, the conventional upper corrugated unit has a substantially trapezoidal cross section, and when the plate material is bent, it comes into contact with the side surface of the adjacent upper corrugated unit. For this reason, when one upper corrugated unit is reversed and removed, the contact frictional resistance with the adjacent upper corrugated unit is large, and the reversing operation requires a great deal of effort. In this way, the work of fixing and removing several heavy upper corrugated units has become hard labor.

ていた。 In addition, in manufacturing bending equipment, the upper corrugated unit must have trapezoidal sides as described above, which makes the processing itself troublesome, and if the dimensions are out of order, the above-mentioned problem will occur. In this case, the upper wave type unit is in pressure contact with the adjacent upper wave type, making it difficult to remove.In such cases, depending on the dimensional error of the upper wave type unit, some parts are easy to remove and others are difficult to remove, which increases fatigue. . Due to these circumstances, strict dimensional accuracy has been required for the upper corrugated unit.

The technical objective is to propose a bending device for long plates that can be easily processed in units.

る。(Operations and Effects of the Invention) As described above, according to the present invention, the upper corrugated unit body 4A has a substantially inverted T-shaped cross section, and there is a wide groove between the upper corrugated unit body 4A and the adjacent upper corrugated unit body 4A. Since the space 12 is formed, when the upper corrugation type 4 is bent into a curved shape when bending the long plate material 1, the adjacent upper corrugation type unit bodies 4A only touch at their tips, and form one. When inverting the upper corrugated unit 4A, the frictional resistance generated between the upper corrugated unit 4A and the adjacent upper corrugated unit 4A is minimized. Therefore, it is easy to reverse the upper corrugated unit body 4A after bending the plate material. Moreover, since each upper corrugated unit body 4A has an inverted T-shaped cross section, it is itself lightweight. Therefore,
The reversing work can be done easily from this point as well.

装置のコストを大幅に低減させることができる。 Furthermore, machining the cross section into an inverted T-shape is easier than machining the cross section into a trapezoidal shape with sloped sides to match the side shape of the lower corrugated unit 3C, as in the past. As described above, since the adjacent upper corrugated mold units 4A have almost no contact surface with each other, strict dimensional accuracy is not required to facilitate the reversing operation of the upper corrugated mold 4. Moreover, the cost of materials is low, so
The cost of the device can be significantly reduced.
