Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a product carry-out device in a turret punch press, particularly a numerically controlled turret punch with an angle shear.
[0002]
[Prior art]
Conventionally, in this type of numerically controlled turret punch press with an angle shear, when a punched product with a micro joint or nesting is carried out, it is cut between the angle shear and then between a fixed table and a moving (slide) table. The product conveyor belt conveyor of the same level as these was lowered by a small amount, and the product was placed on the belt conveyor and carried out.
[0003]
[Problems to be solved by the invention]
However, during punching work on the material (workpiece) of this numerically controlled turret punch press, the belt conveyor and the tables on both sides are at the same level, so the product is scratched on the conveyor surface, causing damage to the product. Or punched punch holes could catch on the conveyor surface and damage them.
[0004]
Further, since the product main body obtained by cutting the micro joint portion and the like with the angle shear is carried out by the conveyor together with the scrap parts, the product and the scrap cannot be sorted well.
[0005]
For this reason, the present invention separates the punching work from the product / scrap carry-out work by angle shear cutting, and the punched holes and the like do not interfere with the carry-out conveyor, thereby reducing the product quality and the conveyor breakage. An object of the present invention is to provide a configuration means for improving the machining tact by separately sorting the body of the angle sheared product and its scrap separately.
[0006]
[Means for Solving the Problems]
For this reason, in the present invention, in the numerically controlled turret punch press with an angle shear having a fixed table, a slide table and a belt conveyor, the angle shear is disposed with a predetermined offset in the horizontal horizontal direction from the punch center, The slide table can be moved horizontally and vertically, and the belt conveyor can be selectively moved horizontally and forward and backward so that the belt conveyor can be exposed and shielded during angle shear processing. This is intended to achieve the object.
[0007]
[Action]
According to the configuration of the present invention as described above, during the turret punch press working operation, the slide table is lifted in the vertical direction and moved to the upper part of the conveyor in the horizontal front-rear direction, and when the angle shear is cut, the slide table is moved. From the upper position of the conveyor to the original position in the horizontal front-rear direction and lowered from the upper surface of the conveyor in the vertical direction, and when scrapping, the conveyor is moved in the horizontal direction between the fixed tables. By operating to provide a space for dropping scraps, there is no fear of damaging the conveyor due to product punch holes or notches during turret punch press work, and larger than the conveyor width during angle shear cutting. Product can be carried out, and product and scrap can be transported in a single conveyor It is possible to sort out, can improve the productivity.

DETAILED DESCRIPTION OF THE INVENTION
The form of the Example of this invention is demonstrated in detail below by one Example.
[0009]
【Example】
(Constitution)
FIG. 1 is a three-plane view ((a) plan view) of the overall configuration of an embodiment of a numerically controlled turret punch press according to the present invention, with respect to each coordinate axis in the horizontal left-right direction X, horizontal front-back direction Y, and vertical direction Z b) Side view, (c) Front view).
[0010]
In FIG. 1, 1 is a turret, 2 is a punch center, and 3 is an angle shear. Reference numeral 4/5 denotes a fixed / slide table, and reference numeral 6 denotes a belt conveyor disposed between the fixed / slide tables 4/5. Reference numeral 7/8 denotes a product carry-out conveyor / scrap carry-out conveyor at the lower part of the frame.
[0011]
Reference numeral 9 denotes an X-axis locating pin, 10 denotes a pair of material (workpiece) clamps, and 10a denotes a workpiece abutting surface. Reference numeral 11 denotes a carriage, 11a denotes a carriage operation panel, 12 denotes an NC console, and 13 denotes a separate hydraulic unit.
[0012]
As shown in FIG. 1, in this embodiment, the angle shear 3 is disposed at a position offset by a predetermined distance in the X-axis direction from the punch center 2, and this cutting position is defined as a cut line 3a (see FIG. 3 described later). Here, the micro joint or the nested product is cut and separated, and the separated product is carried out by the belt conveyor 6.
[0013]
FIG. 2 is an enlarged explanatory view of the main part of the side view of FIG. 1 (b) during punching work, FIG. 3 is an explanatory view of the Z direction up / down and Y direction moving mechanism of the slide table 5, and FIG. The expansion explanatory view of the important section at the time of scrap processing is shown.
[0014]
2, the slide table 5 can move the pedestal 14 up / down by a predetermined height in the Z direction by each cylinder 15 as shown in FIG. 3, and a horizontal cylinder provided on the pedestal 14. 16 is configured to be movable in the Y direction on the slide 14a.
[0015]
As shown in FIG. 2, the belt conveyor 6 is shown in FIGS. 2 and 3 by a linear motion nut 20 on a linear motion guide 19 provided on the belt conveyor frame 18 by a shift cylinder 17 provided on the machine frame. Thus, it is configured to be able to reciprocate a predetermined distance L ₂ in the Y direction.
[0016]
(Operation)
The operation of this embodiment will be described with reference to FIGS.
(1) First, as shown in FIG. 1, the cutting position of the angle shear 3 at a location offset by a predetermined distance in the X direction from the punch center 2 is defined as a cut line.
[0017]
(2) During the punching work, the slide table 5 is raised in the Z direction and moved to the upper part of the belt conveyor 6 on the left side in the X direction as indicated by a two-dot chain line in FIG. Thereby, for example, a product with a hole or a notch in the material can be protected without rubbing against the belt conveyor 6 and normal punching can be performed.
[0018]
(3) On the other hand, when the product is cut by the angle shear 3, the slide table 5 is kept on the right side in the Y direction in FIG. 2, and the product dropped on the belt conveyor 6 as it is can be carried out by the belt conveyor 6. To do. Further, as shown in FIG. 2, the Y-direction width dimension L ₁ of the belt conveyor 6 is slightly lowered by the cylinder 15 of FIG. The above products can be carried out.
[0019]
(4) In addition, at the time of treatment of the scrap S the remainder obtained by cutting and separating the product by Angurushiya 3, as shown in FIG. 4, to move the conveyor belt 6 in the Y-direction right, then the possible space dimension L ₂ It is dropped into the hopper 8a of the scrap delivery conveyor 8 directly below, carried out by the conveyor 8, and discharged into the scrap box 8b.
[0020]
As described above, it is possible to sort and carry out the products and the scraps S with a single conveyor, and an effect that the productivity is remarkably improved can be obtained.
[0021]
【The invention's effect】
As described above, in the numerically controlled turret punch press with an angle shear, the present invention moves the slide table in the Z direction and moves it on the belt conveyor in the Y direction during the punching operation. Because of the construction, there is no fear of damaging the belt conveyor due to punched holes or notches in the product.
[0022]
Further, when the angle shear is cut, the slide table is moved in the Y direction so as to be slightly lower than the height of the belt conveyor surface, so that a product larger than the belt width can be carried out, and the productivity is improved.
[0023]
Furthermore, when scrapping products, the belt conveyor can be retracted in the Y direction, and the scrap can be dropped directly onto the scrap carry-out conveyor from the space formed between them. Therefore, it can contribute to the improvement of productivity.
