Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plate material processing machine, and more particularly to a plate material bending machine that presses and folds a plate material in the thickness direction, or a plate material processing machine such as a plate material cutting machine that presses and cuts a plate material in the thickness direction.
[0002]
[Prior art]
As a plate material processing machine, a plate material bending machine that presses and folds a plate material in the thickness direction and a plate material cutting machine that presses and cuts the plate material in the thickness direction are known. A conventional general plate bending machine is shown in FIG.
The frame 2 has a plate shape and is fixed perpendicularly to the base 1 and is provided with three frames at substantially equal intervals. The frame 2 includes a base part 21 fixed to the base, a support part 22 provided substantially parallel to a position away from the base part 21, and a connection part 23 that connects the base part 21 and one end of the support part 22 to each other. The side shape is substantially U-shaped.
[0003]
A base plate 31 is installed on the other end of the base portion 21 of the three frames 2. The base plate 31 includes a lower blade 32 that can be reciprocated up and down by a spring (not shown), and the lower blade 32 has a V-shaped cross section at the tip. A lifting plate 33 that reciprocates up and down by driving means (not shown) is installed at the other end of the support portion 22, and an upper blade 34 having a V-shaped cross section is provided at the tip of the lifting plate 33. When the elevating plate 33 is lowered, the tip of the upper blade 34 is inserted into the recessed portion of the lower blade 32. A back ruler 5 that reciprocates perpendicularly to the moving direction of the lifting plate 33 and the installation direction of the lower blade 32 is installed on the base portion 21. The processing position of the plate material 10 can be determined by inserting the plate material into the gap between the upper blade 34 and the lower blade 32 and bringing the tip of the plate material 10 into contact with the back ruler 5. The lower blade 32 has a protrusion 35 on the outside. A bent portion of the plate material bent at an acute angle can be inserted into the gap between the protrusion 35 and the base plate 31.
[0004]
Hereinafter, an operation of bending the plate material 10 by the above-described bending machine will be described.
The plate member 10 is inserted into the gap between the upper blade 34 and the lower blade 32 with the lift plate 33 lifted, and the bending position is determined by bringing the tip of the plate member 10 into contact with the back ruler 5. The elevating plate 33 is driven, the upper blade 34 is lowered, the plate material 10 is pressed, and bent according to the V-shaped dent of the lower blade 32. The bending angle is adjusted by adjusting the lower limit reaching position of the lower blade 32.
[0005]
When hemming folding is performed on the plate material 10, the plate material is bent by bending the vicinity of the end of the plate material so that the plate material is refracted to about 30 °, and then the lift plate 33 is driven to raise the upper blade 34 and take out the plate material. Next, the refraction part of the plate material is inserted into the gap between the projection 35 and the base plate 31, the lifting plate 33 is lowered, the lower blade 32 is pushed down by the upper blade 34, and the plate material is pressed by the projection 35 and the base plate 31, The plate material is bent so that it is refracted to about 180 ° and hemming-folded.
[0006]
When the plate member 10 is pressed by the upper blade 34, a stress is applied to the frame 2 so as to spread the base portion 21 and the support portion 22 as indicated by arrows in the figure. If the positional deviation between the upper blade 34 and the lower blade 32 occurs due to this stress, the processing accuracy is lowered. Therefore, the thickness of the frame 2 is increased to ensure the rigidity of the frame 2. In particular, an acute angle folding process or a hemming folding process of about 30 ° bends the plate material with a pressing force 2 to 3 times that of a bending process of about 90 ° by air bending. For this reason, especially high rigidity is required for a frame in order to enable acute angle folding and hemming folding.
[0007]
[Problems to be solved by the invention]
However, conventionally, there has been a problem that the material cost of the frame member becomes high because the thickness of the frame is increased to ensure the rigidity of the frame. Further, when the thickness of the frame is increased, there is a problem that the weight is increased and the transportation cost is increased.
The present invention has been made in view of such problems, and an object of the present invention is to provide a plate material processing machine with high frame rigidity and high processing accuracy.
Another object of the present invention is to provide a highly durable plate material processing machine.
Another object of the present invention is to provide a plate material processing machine having a low manufacturing cost.

[0018]
Hereinafter, an operation of performing hemming folding by the folding plate material processing machine according to the present embodiment will be described.
As shown in FIG. 6, with the lift plate 33 lifted, the plate material 10 is inserted into the gap between the upper blade 34 and the lower blade 32, the tip of the plate material 10 is brought into contact with the contact member 51, and the motor is driven to drive the back ruler. 5 is moved to determine the folding position. At this time, the frame reinforcing plate 41 connected to the back ruler 5 moves together with the back ruler 5 and is positioned near the tip of the plate member 10. Next, as shown in FIG. 7, the lift plate 33 is driven to lower the upper blade 34 to press the plate material 10, and the plate material 10 is bent to about 30 ° according to the V-shaped recess of the lower blade 32. The bending angle of the plate material 10 is determined by the lower reaching position of the upper blade 34. The elevating plate 33 is driven to raise the upper blade 34 to take out the plate material 10, and the refractive portion of the plate material 10 is inserted into the gap between the protrusion 35 and the base plate 2. Next, as shown in FIG. 8, the elevating plate 33 is lowered, the lower blade 32 is pushed down by the upper blade 34, the plate material 10 is pressed by the projection 35 and the base plate 31, the plate material 10 is bent at about 180 °, and hemming folded. Apply processing. At this time, the frame reinforcing plate 41 is located in the vicinity of the processing means 3.
[0019]
When the plate member 10 is pressed, stress acts on the frame 2 in a direction in which the distance between the base portion 21 and the support portion 22 is expanded. The frame 2 is slightly deformed by this stress, and the space between the base portion 21 and the support portion 22 is slightly separated, and the load of the first load support portion 48 and the second load support portion 49 fixed to the frame reinforcing plate 41 is increased. The support surfaces 481 and 491 are in surface contact with the load surfaces 441 and 451 of the first load rail 44 and the second load rail fixed to the support portion 22 and the base portion 21, respectively. When the load supporting surfaces 481 and 491 and the load surfaces 441 and 451 come into surface contact, a tensile stress is generated in the frame reinforcing plate 41, and the stress generated by pressing the plate member 10 is distributed to the frame 2 and the frame reinforcing plate 41. For this reason, deformation of the frame 2 is suppressed. At this time, since the gap between the load support surface 481 and the load surface 441 and the gap between the load support surface 491 and the load surface 451 are extremely narrow, no load is applied to the first slide shaft 42 and the second slide shaft 43. .
[0020]
On the other hand, when bending is performed at a position away from the end face of the plate member 10 except during hemming folding, the frame reinforcing plate 41 moves with the back ruler 5, so the plate member 10 is inserted deeply into the connecting portion 23 side and the plate member 10 is inserted. It can be bent at a position distant from the end face. At this time, since the frame reinforcing plate 41 is closer to the processing position than the connecting portion 23, the deformation of the frame 2 is effectively suppressed.
[0021]
According to the bending plate material processing machine of this embodiment, a tensile stress is applied to the frame reinforcing plate 41 when the plate material 10 is pressed, and the stress acting on the frame 2 is reduced. Therefore, the deformation of the frame is small and the processing accuracy is high.
Further, since the frame 2 can be made thinner than a bending plate material processing machine that does not include the frame reinforcement mechanism 4 and ensures the same level of rigidity, the manufacturing cost is low and the transportation cost is low because of the light weight. Low.
Furthermore, since the stress acting on the frame 2 is small, the durability is excellent.
[0022]
(Second embodiment)
Hereinafter, a cutting plate material processing machine according to a second embodiment of the present invention provided with a frame reinforcing mechanism substantially the same as the frame reinforcing mechanism of the first embodiment will be described.
The cutting plate material processing machine according to the present embodiment has a bed for stably holding the plate material, a driving means positioned opposite to the bed, and a U-shaped side shape connecting the bed and the driving means. And a frame. When the plate material is pressed and cut by the cutting means consisting of the lower cutting blade provided at one end of the bed and the upper cutting blade that moves up and down by the driving means, the reaction force is dispersed on the frame reinforcing plate and the deformation of the frame is suppressed. Is done.
For this reason, according to the cutting plate material processing machine of this embodiment, the deformation of the frame is small, so that the processing accuracy is high.
