In the above-mentioned conventional bending roll machine, the pullback cylinder 7 is operated to raise the elevating frame 4, open the space between the bottom roll 13 and the top roll 23, and place the steel plate or the like to be processed on the bottom roll 13. Then, the bottom roll 13 is rotated by the motor 21 and the pressurizing cylinder 5 is operated to press the top roll 23 against the steel plate on the bottom roll 13 for bending.

[0009]

[Problems to be solved by the device]

 Since the conventional bending roll machine as described above is used for bending large steel plates used for ship hulls in shipyards, etc., it is used infrequently, which causes a problem of cost increase. An object of the present invention is to provide a device which can be used as a pressing machine while not being used as a bending roll machine in order to solve the above problems.

[0010]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a bending roll machine in which a top roll supported by an elevating frame is provided on a pair of bottom rolls on a base frame. Place the lower die mounting member on the bottom die, engage the recesses on both lower sides of the lower die mounting member with the upper portions of both bottom rolls, and place the upper die mounting member for the press on the lower side of the top roll. A structure is adopted in which a recess at the center of the upper part is engaged, and a plurality of positions on the upper side of the upper die mounting member and a plurality of positions of the elevating frame can be tightened and integrated by an adjustable tightening means.

[0011]

[Action]

 When there is no bending of the steel plate and the function as a bending roll machine is temporarily unnecessary, place the prepared lower die mounting member on the bottom roll and place the recesses on both sides of the lower part above the bottom roll. Engage.

Further, the upper die mounting member is applied to the lower side of the top roll to engage the recess with the lower side of the top roll, and tightening means provided at a plurality of locations on the upper side of the upper die mounting member. After connecting the upper end of the upper part to the connecting part provided in the lower part of the lifting frame in advance, operate the tightening step to firmly fix the upper die mounting member to the top roll. After that, the lower die and the upper die are fixed to the lower die mounting member and the upper die mounting member, respectively, and the press work is performed.

【Example】

 FIG. 1 shows an embodiment, and since the bending roll machine shown in FIGS. 2 to 4 is used, only the parts necessary for the embodiment will be described. In FIG. 1, reference numeral 26 designates a lower die mounting member, and since recesses 27 having an arcuate cross section adapted to the outer circumference of the bottom roll 13 are formed on both sides of the lower portion thereof, the interval between both bottom rolls 13 can be adjusted appropriately. The bottom roll 13 is engaged with the recess 27 of the member 26.

Reference numeral 29 is an upper die mounting member, and a recess 30 having an arcuate cross section at the center of the upper surface is engaged with the lower side of the top roll 23, and connecting portions 31 are provided at a plurality of positions on both upper surfaces of the mounting member 29. On the other hand, the lower end of the fastening means 32 is detachably and rotatably connected to each of the connecting portions 31 by a pin.

A connecting portion 33 corresponding to each connecting portion 31 is provided at the lower end of the elevating frame 4, and the upper end of the fastening means 32 is detachably and rotatably connected by a pin. In the case of the embodiment, the tightening member 32 is a turnbuckle type in which upper and lower bolts, which are reverse-threaded, are screwed into a screw cylinder, which is internally threaded in the reverse direction. Stuff available.

Further, a plurality of T-shaped grooves 34 and 35 are respectively provided on the upper surface of the lower die mounting member 26 and the lower surface of the upper die mounting member 29 to facilitate the mounting of the lower die and the upper die for press working. . The operation of the above-described embodiment will be described. While the use as a bending roll machine is suspended, the lower die mounting member 26 prepared in advance is placed on the bottom roll 13 and the recesses 27 on both sides of the lower portion are formed. Engage with the upper side of the bottom roll 13 to stabilize horizontally.

Further, the upper die mounting member 29 is applied to the lower side of the top roll 23 to engage the recess 30 with the lower side of the top roll 23, and is connected to a plurality of locations on the upper side of the upper die mounting member 29. The upper end of the tightening means 32 is connected to the connecting portion 33 provided in the lower part of the elevating frame 4 in advance, and then the screw cylinder of the tightening means 32 is rotated to secure the upper die mounting member 29 to the top roll 23. And horizontally. After that, the lower die and the upper die are fixed to the lower die mounting member 26 and the upper die mounting member 29, respectively, and a pressing operation is performed.

[0018]

[Effect of device]

 As described above, this invention can easily attach the lower die mounting member and the upper die mounting member on the bottom roll of the resting bending roll machine and the lower portion of the top roll. By using this bending roll machine as a substitute for the hydraulic press, the frequency of use can be increased.

Also, by engaging the recesses on both lower sides of the lower die mounting member with the upper portions of both bottom rolls, the lower die mounting member is stabilized, and the lower die of the top roll is mounted with the upper die of the press machine. The upper center of the member is engaged with the recess, and the upper part of the upper die mounting member and the ascending / descending frame are tightened by the adjustable tightening means to be integrated. In addition, the lower die mounting member and the upper die mounting member can be easily attached and detached.
