DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to wire mesh bending machine for bending to Gesuru the end of the wire mesh sheet <br/> repeated under songs Therefore in a substantially tubular cage.

[0002]

2. Description of the Related Art A wire mesh screen knitted with vertical and horizontal (detailed) wires.
The fences welded at the intersections are light and strong, and can be used in modern buildings, etc., and have become popular in recent years. In this welded wire mesh sheet fence, a tubular portion for inserting a frame or a support post is formed at an end of the wire mesh sheet. It is rare. In the conventional bending method, a metal core is applied along the end of a welded metal mesh sheet fence, and bending is performed so that the metal mesh sheet end is wound around the metal core, or a tool around the metal core is vertically moved. It was folded in a substantially cylindrical shape by pressing from the front and back.

[0003]

However, since this core metal is applied to the wire mesh sheet in a state where both ends are supported, it becomes longer than the length of the wire mesh sheet end. And, when the pressing and bending is performed by the tool, even if the pressing force is performed with a uniform distribution load along the longitudinal direction of the core metal, the rigidity of the core metal is low. The center becomes more flexed, and the ends of the wire mesh sheet become drum-shaped as a whole. Since the aesthetic appearance would be impaired if it was used, it was necessary to rework the drum-shaped thing into a cylindrical body. In addition, since the bending is performed in the up-down and front-rear directions, the handling of the wire mesh sheet is complicated, and the cost is high. The present invention has been made to solve the above problems, stiffness is large, easy die cutting, and an object thereof is to provide a wire mesh bending machine Ru cormorants play an equally shaped.

[0008]

The wire mesh sheet is intermittently fed onto the male mold. The female mold repeatedly presses the end of the wire mesh sheet on the male mold to bend into a substantially cylindrical basket shape. After bending, if the wire mesh sheet is shifted in the axial direction of the end of the substantially cylindrical cage, the vertical and horizontal wires arranged in the forward direction can be taken out from the clearances of the divided male mold pieces. The male mold is not long as in the prior art, but is divided into a plurality of divided male mold pieces.

It should be noted that the side positioning cylinder can be omitted if the die cutting cylinder 9 has a side positioning function.

(Upper and Lower Mold Assembly) The upper mold assembly 20 is fixed to the ram 3 (FIGS. 1 and 2). The ram 3 is moved up and down by the main cylinder 5 with respect to the bed 2. A rotary die, which is a female die 22, is rotatably provided on the holder 21 constituting the upper die assembly 20 (FIG. 4).
The female mold 22 repeatedly presses the wire mesh sheet 50 on the male mold 13 and is urged in a counterclockwise direction by a spring 23 to return to an initial rotation position. A reaction force receiving member 27 projects downward at a position corresponding to the center of the machine of the upper die assembly 20. The reaction force receiving member 27 fits into the reaction force receiving groove 17 formed in the lower die holder 11, and the upper die assembly 20 and the lower die assembly 10 are moved in the front-rear direction (left-right direction in FIG. 4) during processing. No deviation occurs. In addition, near the female mold 22 of the upper mold assembly 20,
A step 26 is formed to hold the pressure transmitting surface of the upper mold 30 when the auxiliary upper mold 30 is rotated in reverse as described below.

(Auxiliary Upper Die 30) The upper die assembly 20 is provided with an auxiliary upper die 30. This auxiliary upper mold 30
Is for upward bending, and is for bending a neck portion 55 (FIG. 16), which is bent into the substantially cylindrical cage end 53 of the wire mesh sheet 50, in a direction opposite to the bending by the female mold 22. . That is, it is rotatably mounted on an axis parallel to the bending line on the side of the upper die holder, and is turned to the retracted position (solid line in FIG. 4) at the time of repeated downward bending of the end of the wire mesh sheet. At the time of the last step bending, the female mold 22 is approached from the retracted position so as to cooperate with the male mold 13 to bend the neck 55 at the substantially cylindrical cage end (the imaginary line in FIG. 4).

And a rack 34 formed on the piston rod of the driving cylinder 32, a pinion 33 meshing with the rack 34, and the shaft 31 fixed to the axis of the pinion 33.

(Wire mesh feeding conveyor 6) The wire mesh sheet 50 is advanced between the male mold 13 and the female mold 22, and this advance is performed by the metal mesh feeding (forward feeding) conveyor 6 (FIGS. 2 to 4). The wire mesh sheet 50 whose end in the forward direction is bent by this advance is further fed rightward in the figure by the wire mesh feed conveyor 7 (FIGS. 2 and 3). At this time, a reaction force receiving member 27 is provided at the center of the machine so that the rear end of the wire mesh sheet 50 in the forward direction is similarly bent, and a male type, a female type,
Side positioning means for moving the vertical wire of the auxiliary upper die, the die cutting cylinder, the lifter, and the wire mesh sheet are arranged at symmetrical positions in the front-rear direction. The wire mesh sheet folding machine 1 of this embodiment is symmetrical in forward and backward directions of advance (FIGS. 2 and 3). A lifter 35 is provided on a part of the gap 16 of each of the divided male molds 13.
(FIGS. 1, 2, and 4) are attached, and can be moved up and down by a lifter cylinder. By raising the lifter bar 37, the wire netting sheet 50 can be easily raised and sent out after the die-cutting.

(Side Positioning Cylinder) As described above, the wire mesh sheet 50 is fed by the wire mesh feeding conveyor 6 and the wire mesh sending conveyor 7, and at this time, the wire mesh sheet 50 is provided with the side guide rails provided on the left and right in the feeding direction. Guided on the basis of 8. However, there is a slight gap between the side guide rail 8 and the wire mesh sheet 50, and finally, the positioning in the left and right direction is performed by side positioning with the die-cutting cylinder 9.
That is, the wire mesh sheet 5 is positioned by side positioning.
By moving 0 in the left-right direction (the substantially cylindrical portion of the wire mesh sheet 50 is in the axial direction of the bar-shaped end portion 53), the vertical wire 51 constituting the wire mesh sheet 50 is positioned in the divided male-shaped gap 16. At this time, the lifter 35 is operated, and the wire mesh 50 is
3 can be removed.

(Bumping Device 40) When the bending process is performed, the wire mesh sheet 50 must be advanced intermittently by a predetermined size. The predetermined size is determined by the butting cage 40. That is, as shown in FIG.
The butting device 40 is attached to a position where the leading end of the wire mesh sheet 50 to be sent and the rear end of the wire mesh sheet 50 to be sent are located. This butting device 40
The four types of abutting blocks 41, 42, 43, and 44 are provided so as to protrude in the front-rear direction with respect to a gauge base that slides in the left-right direction of the wire mesh sheet 50 by a butting cylinder 45. The amount of protrusion differs depending on each abutment block 41, 42, 43, 44.
The forward dimension of the gate 50 is determined.

(Abutment block) Abutment cylinder 4
When the wire 5 is completely extended, all butting blocks are retracted from the space where the wire mesh sheet 50 is fed (the chain lines in FIGS. 3 and 7). If the first abutment block 41 having the largest projection amount is retracted, the second abutment block 42 having the second largest projection amount works to determine the forward dimension of the wire mesh sheet 50. Similarly, if the second butting block 42 is retracted, the third
If the third butting block 43 is retracted, the fourth butting block 44 will work.

The operation of this embodiment will be described below with reference to FIGS. (First Step) First, the wire mesh sheet 50 is fed by the wire mesh feeding conveyor 6.
At this time, the abutment cylinder 45 is contracted, and the first to fourth abutment blocks 41, 42, 43, and 44 are arranged in the feed space of the wire mesh sheet 50, and the first protrusion having the largest amount of protrusion is provided. Only the butting block 41 works to come into contact with the leading end of the wire mesh sheet 50 (FIG. 9). As a result, a predetermined forward dimension of the wire mesh sheet 50 required for the first step is obtained. Thereafter, the ram 3 is lowered, and the female die 22 of the upper die assembly 20 presses the wire mesh sheet 50 onto the male die 13 while rotating as shown by the arrow, thereby performing the first downward bending (FIG. 10). . Next, the ram 3 rises and the female mold 22 becomes the male mold 1.
Move away from 3. Then, the wire mesh feeding conveyor 6 works again, and the wire mesh sheet 50 advances by a predetermined distance .

(Second Step) At this time, the butting cylinder 45 is slightly extended, the first butting block 41 is retracted from the feed space of the wire mesh sheet 50, and the second butting block 42 is moved to the wire mesh sheet. Contacts the tip of the gate 50. As a result, the required predetermined advance size in the second step is obtained (FIG. 11). After that, the ram 3 descends again and the female mold 2
2 presses the end of the wire mesh sheet 50 onto the male mold 13.
At this time, the reaction force receiving member 27 is fitted into the reaction force receiving groove 17 to support the bending reaction force. In this manner, the wire mesh sheet 50 is gradually bent, and is subjected to the second downward bending along the fan-shaped arc of the male mold 13 (FIG. 12). After processing
The ram 3 rises again, and the female mold 22 separates from the male mold 13.

(Third Step) While the second step has been completed and the ram has been raised, the wire mesh sheet 50 advances again, and the end comes into contact with the third butting block 43, and the required predetermined amount is reached. (FIG. 13). Next, the third downward bending is performed by the downward rotation of the female mold 22 (FIG. 14).

(Fourth Step) Next, in the fourth step, not only the male mold 13 is bent along the fan-shaped circular arc, but also the neck which is bent in this manner to form the substantially cylindrical basket-shaped end 53. The bending of the portion 55 (FIG. 15) takes place. That is, the auxiliary type cylinder 32 operates, the rack 34 descends, and the pinion 33 rotates, whereby the auxiliary upper die 30 rotates around the axis 31 and projects toward the lower lower die assembly 10. (FIG. 4). Also, the butting cylinder 45 extends further, and only the fourth butting block 44 remains in the feed space of the wire mesh sheet 50. When the wire mesh sheet 50 is advanced by the wire mesh feeding conveyor 6 in this state, the leading end of the wire mesh sheet 50 comes into contact with the fourth butting block 44, and a predetermined advancing dimension is obtained. In this state, the ram 3 descends, and the auxiliary upper die 30 presses the wire mesh sheet 50 to start bending. At the same time, the front end of the female mold 22 presses the wire mesh sheet,
The wire mesh sheet 50 starts to be bent along the shape of the male mold 13. Furthermore, the bending by both proceeds, and finally the wire netting sheet 50 whose end is bent into a substantially cylindrical basket 53 can be obtained (FIG. 16).

(Die-cutting) After the bending process is completed in this way, the die-cutting cylinder 9 operates to move the wire mesh sheet 50.
Moves by a distance s in the left-right direction (axial direction of the bag-like end). By this movement, the vertical wire 51 of the wire mesh sheet 50 is positioned at the gap 16 of the divided male mold 13 (FIG. 9). afterwards,
The lifter cylinder 36 works, the lifter bar 37 rises,
Lift the wire mesh sheet 50 (FIG. 16). This allows
The vertical wire 51 of the wire mesh sheet 50 passes through the gap 16,
The wire mesh sheet 50 is die-cut from the male mold 13. Thereafter, the wire mesh sheet 50 is moved to the middle right side in FIG. 2 by the wire mesh feeding conveyor 6 and the wire mesh sending conveyor 7.

The processed front end of the wire mesh sheet 50 is transferred from the delivery conveyor 6 to the delivery conveyor 7. Here, by sequentially feeding the feed conveyor in the reverse direction, the rear end of the wire mesh sheet 50 can be bent into a substantially cylindrical basket 53 through exactly the same steps as described above. That is, the wire mesh sheet 50 is intermittently retracted by a predetermined dimension by the butting cylinder 45 (moving to the left in FIG. 2).
The same bending process can be performed by repeating the pressing by the female mold 22 by moving the female die 22 forward. Then, the wire netting sheet 50 is cut out again by the operation of the die cutting cylinder 9 and the lifter bar 37, and the wire netting conveyor 7 completely feeds the wire netting sheet.

The male mold 13 does not support a long one at both ends like a conventional cored bar, but divides it into a plurality and supports each divided male mold in a cantilever state to increase rigidity. , The pressing force applied to the female mold 22 is strong.
And the support arm 14. In addition, the bending caused by the pressing of the female mold 22 in each divided male mold piece is uniform. For this reason, it is possible to prevent the substantially cylindrical cage-like end portion 53 of the wire mesh sheet 50 from being deformed like a drum due to a large bending at the center as in the case of a conventional cored bar supported at both ends. For this reason, the aesthetic appearance of the processed wire mesh sheet 50 is not spoiled. Also, there is no need to modify the drum-shaped deformation.

Furthermore, by repeatedly pressing the female mold 22 while intermittently moving the wire mesh sheet 50 over the male mold 13 by a predetermined dimension, the end 53 of the wire mesh sheet 50 can be easily bent. . For this reason, compared with the case where the core metal applied to the end of the wire mesh sheet 50 is pressed and bent using a tool from the top and bottom and the front and rear as in the related art,
Is easy to handle, and the processing cost can be kept low. In the above embodiment, the end portion 53 of the wire mesh sheet 50 is substantially cylindrical (FIG. 16). However, in other embodiments, a substantially cylindrical shape other than the substantially cylindrical shape, for example, a regular polygonal cross section is used. It may be a bent end 53a (FIG. 17) or a bent end 53b having a triangular cross section (FIG. 18).

[0027]

As described above, claim 1 or claim 2
According to the invention, the male mold is divided into a plurality of pieces, and each of the divided male mold pieces is individually supported, so that the center of the long male mold (core metal) may be bent as in the related art. In addition, it is possible to prevent the substantially cylindrical shape at the end of the wire mesh from being deformed into a drum shape. For this reason, the beauty | look of a wire mesh can be improved, and the effort for reworking a drum shape into a substantially cylindrical shape becomes unnecessary. In addition, the wire mesh can be folded repeatedly by the female mold while being intermittently advanced by a predetermined dimension over the male mold, so that a substantially cylindrical bending can be performed. Bending processing costs can be suppressed. Since the male mold has a cross-sectional shape corresponding to the upper half of the substantially cylindrical cage end of the wire mesh, the weight of the male mold can be reduced, and the weight of the wire mesh bending machine can be reduced. Furthermore, the rigidity of the mold is high, the mold can be easily removed, and uniform molding is possible.
