Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep groove corrugated multi-curve press device used for manufacturing a deep groove corrugated plate material by pressing and bending a flat plate material.

[0002]

2. Description of the Related Art A deep groove corrugated multiple bending press is composed of a plurality of corrugated upper and lower molds, and a flat plate material is sandwiched between the upper mold and the lower mold for pressing. It is like this. Since the conventional deep groove corrugated multiple bending press machine has a small number of upper molds and lower molds, the number of deep grooves formed by one press is small. Therefore, when processing a wide flat plate material, the pressing operation had to be repeated many times. Therefore, the process becomes very complicated, and there is a drawback that it takes a lot of labor and time.

In order to eliminate such drawbacks, the number of upper molds and lower molds is increased to increase the number of deep grooves that can be formed by one press. However, the mechanism for synchronizing the descending speed of the upper mold and the horizontal moving speed of the upper mold and the lower mold is extremely complicated. For this reason, many of them are mechanically unreasonable or do not work reliably, and there is a problem in terms of safety.

[0004]

The problem to be solved by the present invention is that a large number of deep grooves can be formed by one pressing operation, and the overall processing time can be greatly shortened. It is to provide a deep groove corrugated multiple bending press device having a simple structure, good operability, and excellent safety.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention, which has solved the above problems, is to mount a plurality of corrugated upper molds on a lower surface of a ram head of a press device so as to be slidable in a horizontal direction, and to mount a plurality of corrugated lower molds on a table upper surface. A metal mold is placed, and the corrugated lower mold at the center is removed so that it can be slid horizontally, and the corrugated upper mold and the corrugated lower mold are equipped with sliding reciprocating cylinders. A rack gear is horizontally supported on the end faces of the mold and the lower mold of the same waveform, and a plurality of pinion gears are rotatably provided at the central position of the upper mold of the same waveform and the central position of the lower mold of the same waveform. Two front rack gears axially supported by the same wave-shaped mold which are in line symmetry with respect to each other, are meshed with one front pinion gear, and similarly, they are in line symmetry with respect to each other with the central part sandwiched. It was pivotally supported on the lower mold of the same waveform In deep groove waveform multiplexing songs pressing device, wherein a rack gear supra the book is meshed in one of the preceding pinion gear.

[0006]

The deep groove corrugated multiple bending press apparatus of the present invention is provided with a plurality of corrugated upper molds and a plurality of corrugated lower molds.
A plate material is sandwiched between the same waveform upper mold and the same waveform lower mold, and while lowering the same waveform upper mold, the same waveform upper mold and the same waveform lower mold are slid horizontally toward the center. Move and push the plate material. Sliding of the upper die of the same waveform and the lower die of the same waveform is performed by respective reciprocating cylinders for sliding.

The upper molds having the same waveform and the lower molds having the same waveform, which are line-symmetrical to each other with respect to the central portion, must slide in synchronization with each other toward the central portion. For this reason, two rack gears axially supported on the end surface of the same-waveform die at the line symmetrical position are meshed with one pinion gear at the central position. Similarly, the shaft 2 is axially supported on the end surface of the lower corrugated mold having the same waveform at the line symmetrical position.
This rack gear is meshed with one of the pinion gears at the central position. If there are several sets of same-waveform upper molds and same-waveform lower molds that are line-symmetrical positions, two rack gears are similarly meshed with one pinion gear for each set.

[0008] As described above, two rack gears are meshed with one pinion gear for the upper molds of the same waveform and the lower molds of the same waveform which are line-symmetrical to each other with the center portion sandwiched therebetween. The horizontal sliding movements of the upper and lower corrugated dies are completely synchronized with each other. Even if the number of dies having the same waveform and the number of dies having the same waveform are large, complete synchronization can be obtained by the above-mentioned meshing mechanism. That is, it becomes a deep groove waveform multiple bending press device capable of forming many deep grooves by one pressing operation.

For this reason, it is possible to significantly save labor compared with the conventional method, and it is possible to shorten the entire processing time.

Corrugated upper molds 1, 4 and 2, 3 in line symmetrical positions with the central portion sandwiched therebetween, and corrugated lower molds 6, 1 similarly.
0s and 7 and 9 must slide toward the same central portion in synchronization. Therefore, as described above, the meshing mechanism is such that two rack gears provided horizontally from the left and right toward the center portion mesh with one pinion gear at the center position. Therefore, the horizontal sliding movements of the corrugated upper molds and the corrugated lower molds at the line-symmetrical positions are completely synchronized, and the press work can be smoothly performed. In addition, since there is no mechanical overload, safety is high, and since the rack gear and pinion gear are combined, the structure is simple and the operability is good. In addition, corrugated upper molds 1, 2, 3, 4 and corrugated lower molds 6, 7, 8, 9, 1
0 must slide while maintaining a positional relationship in which they mesh with each other, and this is synchronized by controlling the hydraulic mechanism that operates each sliding reciprocating cylinder 11.

In the deep groove corrugated multiple bending press apparatus of this embodiment, four corrugated upper molds 1, 2, 3, 4 and five corrugated lower molds 6, 7, 8, 9, 10 are attached. However, it is also possible to further increase the numbers of the corrugated upper mold and the corrugated lower mold.

FIG. 6 shows another embodiment. Reciprocating cylinders 29, 3 for sliding the corrugated lower molds 27, 28 respectively
It is designed to slide at 0. The sliding reciprocating cylinder 29 is fixed to the table 5, and the sliding reciprocating cylinder 3
0 is fixed to the corrugated lower mold 28. If the operating speeds of the sliding reciprocating cylinders 29 and 30 are V and v, respectively,
The sliding speed 31 of the corrugated lower mold 28 is V, and the sliding speed 32 of the corrugated lower mold 27 is V + v. Normal corrugated bottom mold 2
Since 7 must slide at twice the speed of the corrugated lower die 28, an appropriate sliding speed can be easily obtained by setting V = v in this mechanism. Corrugated mold 33,34
Also, the same mechanism is provided by providing reciprocating cylinders 35 and 36 for sliding. The corrugated upper mold 33 is located at the center between the corrugated lower molds 27 and 28, and the corrugated upper mold 3 is located at the center between the corrugated lower molds 28 and 37 during sliding by pressing.
Reciprocating cylinder 2 for sliding so that 4 remains in the position
It controls the hydraulic mechanism of 9, 30 and 35, 36.

Regarding the sliding distance, the corrugated lower mold 27 has to slide twice as much as the corrugated lower mold 28. According to this mechanism, it is not necessary to use a reciprocating cylinder for sliding having a long stroke. Since it is eliminated, the lateral length of the deep groove corrugated multiple bending press device can be shortened, and the installation space can be made small.
