  Hereinafter, embodiments according to one aspect of the present disclosure (hereinafter, also referred to as “this embodiment”) will be described based on the drawings.

(Example of application)
First, an example of a scene to which the present disclosure is applied will be described based on FIGS. 1 and 2. FIG. 1 is a plan view showing a configuration of a pressing system 1 provided with a pressing apparatus 10 according to an embodiment of the present disclosure. FIG. 2 is a perspective view showing the entire configuration of the pressing apparatus 10. As shown in FIG.

  As shown in FIG.1 and FIG.2, the press processing apparatus 10 in 1 aspect of this indication presses the to-be-processed material M conveyed by several press molding line 30a * 30b. At that time, the press processing apparatus 10 is provided with a pressing member 14 that simultaneously presses and processes the workpiece M in the plurality of press forming lines 30a and 30b. The plurality of press forming lines 30a and 30b intersect with each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. Each of the press forming lines 30a and 30b is linear at least in the pressing area.

  According to the present configuration, when the work members M of the plurality of press forming lines 30a and 30b are simultaneously pressed and formed by the pressing member 14, the plurality of press forming lines 30a and 30b are pressed by the pressing member 14 At the center point 16b of the pressing area 16a to which the pressure is applied, they intersect with each other. The crossing angle can be, for example, 60 degrees.

  For this reason, since the workpieces M of the plurality of press forming lines 30a and 30b are simultaneously pressed by one pressing member 14, it is possible to simultaneously produce a plurality of molded articles of different materials and different plate thicknesses.

  In particular, in one aspect of the present disclosure, the plurality of press forming lines 30a and 30b cross each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. Each of 30 a and 30 b is linear in at least the pressing area of the pressing member 14.

  Therefore, no eccentricity occurs when a pressing force is applied by the pressing member 14. As a result, since the pressing force can be applied uniformly to the workpieces M of the plurality of press forming lines 30a and 30b, the quality of the formed product becomes good in any of the press forming lines 30a and 30b. .

  Furthermore, in one aspect of the present disclosure, each of the plurality of press forming lines 30a and 30b is linear at least in the pressing area of the pressing member 14, and sterically intersects each other at the center point 16b of the pressing area 16a. There is. As a result, the center of gravity of the pressing force gathers at the intersection of all the press forming lines 30a and 30b regardless of the presence of the missing press forming lines 30a and 30b. As a result, even if a drop occurs in any of the plurality of press forming lines 30a and 30b, it does not affect the press forming line 30a other than the dropped line, for example, the press forming line 30b, and the press is not missing. The molding line 30a can be pressed uniformly.

  Therefore, it is possible to provide the press working apparatus 10 that can press without breaking the pressure balance of the pressing member 14 even if a missing line occurs in any of the plurality of press forming lines 30a and 30b.

  In one aspect of the present disclosure, in addition, the plurality of press forming lines 30a and 30b cross each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. This means that the plurality of press forming lines 30a and 30b extend radially, and the distance between the adjacent press forming lines 30a and 30b increases with distance from the center point of the crossover. Means

  As a result, when the workpiece feeding devices 20 and 20 for conveying and driving the workpieces M of the press forming lines 30a and 30b along the lines are installed, the workpiece feeding devices 20 and 20 interfere with each other. Can be prevented.

(Example of configuration)
The structure of the press processing system 1 provided with the press processing apparatus 10 of this Embodiment is demonstrated based on FIGS. 1-5. FIG. 1 is a plan view showing a configuration of a pressing system 1 provided with a pressing apparatus 10 in the present embodiment. FIG. 2 is a perspective view showing the entire configuration of the pressing apparatus 10. As shown in FIG. FIG. 2 shows a state in which the pressing apparatus 10 is compressed. FIG. 3A is a cross-sectional view showing the configuration of the molds 11A and 12A of the press processing apparatus 10 and the pressing member 14. As shown in FIG. (B) of FIG. 3 is a cross-sectional view showing the configuration of a mold and a pressing member of a modified example of the pressing apparatus 10. As shown in FIG. FIG. 4 is a plan view showing the configuration of the interference avoiding unit 18 of the pressing apparatus 10. As shown in FIG. FIG. 5 is a front view showing the configuration of the press 40 in the press processing apparatus 10. As shown in FIG.

  As shown in FIG. 1, the press working system 1 of the present embodiment is a press forming comprising one press working apparatus 10, two work material feeding apparatuses 20, and two lines of press forming lines 30a and 30b. A line 30 and a press 40 shown in FIG. 5 are provided.

  The press processing apparatus 10 of the present embodiment forms a molded product by pressing the workpieces M conveyed by the press forming lines 30 a and 30 b which cross each other at three-dimensional crossing which is the press forming line 30.

  For this reason, the workpiece feeding device 20 is configured to transport the strip-shaped workpiece M constituting the press forming line 30. The work material M is pressed by holding the press processing apparatus 10 with a press 40 so as to move a press member 14 described later of the press processing apparatus 10 downward. In the present embodiment, at least any one of the thickness, the width, and the grade of the workpiece M may be the same or different.

  In each of the two press forming lines 30a and 30b, the workpiece M is conveyed, and a molded article having a desired shape is formed by the molds 11 and 12 of the press processing apparatus 10. FIGS. 1 and 2 describe the case where the press forming line 30 is composed of a plurality of two press forming lines 30a and 30b.

  By the way, as described above, the press working apparatus 10 of the present embodiment is provided with the two lines of press forming lines 30a and 30b for pressing the material to be processed M to be conveyed.

  Conventionally, in a press working apparatus, in order to form a large number of desired molded articles from a work material, as shown in FIG. 9A, for example, a large number of molded articles are obtained by a single row press molding line. The thing was done. However, in the case of a large number of units, although it is possible to form a molded product having the same shape or a different shape from one strip-shaped workpiece, only molded products of the same material and the same plate thickness may be molded. I can not

  Therefore, in order to form a molded product having the same or different shape with different materials or different plate thicknesses, as shown in FIG. 9 (b), two rows of press forming lines are provided in parallel, for example. It is conceivable to perform multi-ordering, etc.

  However, in the case where a plurality of press forming lines are provided in parallel, there is a problem in that if there are missing lines, the mold balance is disturbed and the productivity is lowered. The reason is that even if two rows of press forming lines are provided in parallel, since there is only one press, one flat pressing member covering the two rows of parallel press forming lines is provided. In order to press. That is, when one row of the two rows of press forming lines is missing, the horizontality of one pressing member can not be maintained, the load on the mold changes, and the left and right direction of movement of the press forming line is uniform. It will be difficult to apply power. As a result, it is difficult to form a molded product with high accuracy.

  Therefore, in the press working apparatus 10 of the present embodiment, as shown in FIGS. 1 and 2, for example, pressing force by the pressing member 14 is applied to the two press forming lines 30 a and 30 b as the press forming line 30. At the center point of the center point 16b of the pressing area 16a, the two intersect with each other.

  Specifically, the press processing apparatus 10 has, for example, an octagonal planar shape, and as shown in FIG. 2, the press base 10 is provided on the upper side and moved in the upper and lower direction. And a possible pressing member 14. Between the fixed base 13 and the pressing member 14, as shown in FIG. 3A, a die plate 15 which is a lower substrate and a die provided corresponding to each press forming line 30a, 30b. 11 and 12 and an upper height adjusting member 16 are provided.

  In FIGS. 3A and 3B, the press forming lines 30a and 30b are illustrated as being arranged in parallel for the sake of convenience for easy understanding. As shown in FIG. 2, the press forming lines 30a and 30b cross each other.

  As shown in FIG. 3A, the mold 11 provided corresponding to the press forming line 30a comprises the lower mold 11a and the upper mold 11b, while provided corresponding to the press forming line 30b. The mold 12 to be made consists of a lower mold 12a and an upper mold 12b. In the present embodiment, the upper surface position of the lower mold 12a is higher than the upper surface position of the lower mold 11a.

  The die plate 15 is a substrate common to the press forming lines 30a and 30b, and is a plate which is placed on the fixed base 13 and on which the molds 11 and 12 are placed. In the present embodiment, the die plate 15 is integrally formed with the lower mold 12a and the lower mold 11a.

  The upper height adjusting member 16 is provided between the upper mold 11 b and the upper mold 12 b and the pressing member 14. In the present embodiment, the upper height adjusting member 16 is integrally formed with the upper mold 11b and the upper mold 12b.

  The upper height adjusting member 16 is formed such that the distance between the lower mold 11a and the upper mold 11b and the distance between the lower mold 12a and the upper mold 12b are equal to each other. The upper surface of the upper height adjusting member 16 is adjusted to be in close contact with the lower surface of the pressing member 14 in a horizontal state.

  The pressing member 14 is supported by four expandable coil springs 17 provided upright on the fixed base 13. Then, as shown in FIG. 5, the pressing member 14 is moved downward by being pinched and pressed between the mounting table 41 of the press 40 and the compression unit 42, and the compression unit of the press 40 is moved. By releasing the pressure of 42, the coil is moved upward by the biasing force of the coil spring 17.

  Here, in the above description, as shown in FIG. 3A, the die plate 15 is integrally formed with the lower mold 12a and the lower mold 11a, and the upper height adjustment member 16 is an upper part It has been described that it is integrally formed with the mold 11 b and the upper mold 12 b. However, the molds 11 and 12 are not necessarily limited thereto. For example, as shown in FIG. 3 (b), the molds 11 and 12 can be made of replaceable cassette molds. Thus, by replacing the cassette mold, molded articles having the same or different shapes can be easily molded in the press molding lines 30a and 30b.

  Here, in the present embodiment, as shown in FIG. 1, two molds 11A and 11B and molds 12A and 12B are provided in each of the press forming lines 30a and 30b. The molds 11A and 11B and the molds 12A and 12B are provided at positions symmetrical with respect to the intersection of the press forming lines 30a and 30b. Thereby, during conveyance of the workpiece M in each of the press forming lines 30a and 30b, two molded articles having the same shape or different shapes can be formed in one press, and therefore, the productivity is improved. In particular, in the present embodiment, the molds 11A and 11B and the molds 12A and 12B are respectively provided at positions symmetrical with respect to the intersection of the press forming lines 30a and 30b. As a result, the pressure balance of the pressing member 14 is not disturbed with respect to all the molds 11A and 11B and the molds 12A and 12B.

  Next, in the press working apparatus 10 according to the present embodiment, as shown in FIG. 4, columnar interference avoidance sections 18 are provided at concentric intersections in each of the press forming lines 30 a and 30 b which intersect three-dimensionally. In the interference avoiding portion 18, through holes 18a and 18b having different heights for passing the respective press forming lines 30a and 30b are formed. In the present embodiment, the difference in height of the through holes 18a and 18b is, for example, 2.5 mm. However, the height difference is not necessarily 2.5 mm, and may be larger or smaller.

  The operation | movement which processes the to-be-processed material M using the press processing apparatus 10 of the said structure is demonstrated.

  First, as shown in (a) and (b) of FIG. 3, predetermined molds 11 and 12 are set in the press processing apparatus 10 in each of the press forming lines 30 a and 30 b. The molds 11 and 12 may be fixed molds or may be easily replaceable cassette molds.

  Next, for example, the press processing apparatus 10 is placed between the mounting table 41 and the compression unit 42 of the press 40 illustrated in FIG. 5. Thereafter, the strip-shaped workpiece M of the press molding line 30a is passed between the lower mold 11a and the upper mold 11b of the press processing apparatus 10, and the lower mold 12a and the upper mold 12b of the press processing apparatus 10 The strip-shaped workpiece M of the press forming line 30b is passed between. The order of setting the press machine 40 in the press processing apparatus 10 and passing the strip-shaped workpiece M through the molds 11 and 12 may be earlier.

  Next, the workpieces M of the press forming lines 30a and 30b are conveyed by the workpiece feeding device 20 shown in FIG. As a result, the workpieces M of the press forming lines 30a and 30b move along the press forming lines 30a and 30b.

  The workpiece feeder 20 is configured to transport the workpiece M by, for example, a pulse motor. Therefore, the workpiece M moves when the pulse motor is on, and stops when the pulse motor is off. Therefore, when the workpiece M is stopped, the pressing member 14 is moved downward by the compression unit 42 of the press 40. As a result, the workpiece M is pressed by the molds 11 and 12 and molded. In the forming process, the workpiece M may be cut into a predetermined shape, or may be formed into a predetermined shape.

  FIG. 6 is a plan view showing a state in which the press working apparatus 10 is missing. For example, as shown in FIG. 6, there may be a case where, for example, the press forming line 30b, which is one line to the press forming line 30, is in a non-row state. However, in the press working apparatus 10 according to the present embodiment, the pressing force is applied uniformly to the workpieces M of all of the plurality of press forming lines 30 regardless of the presence of the broken press forming lines 30. It is possible to As a result, even if a missing row occurs in any of the plurality of press forming lines 30a and 30b, it does not affect the press forming line 30a other than the dropped row, for example, the press forming line 30b. The workpiece M can be pressed uniformly.

  Therefore, it is possible to provide the press working apparatus 10 capable of pressing without breaking the pressure balance of the pressing member 14 even if a row is generated in any of the plurality of press forming lines 30.

  In the above description, the case where the press forming line 30 includes a plurality of two line press forming lines 30a and 30b is described. However, the present invention is not necessarily limited thereto. For example, as shown in FIG. 7, a press forming line 30 c as the press forming line 30 can be additionally provided. As a result, simultaneous production of a plurality of molded articles of a plurality of types of workpieces M becomes possible simultaneously, and the productivity is improved. In addition, in the press working apparatus 10 in one aspect of the present disclosure, four or more lines can be provided as the press forming line 30.

Equipped with The plurality of press forming lines 30a and 30b intersect with each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. Each of the press forming lines 30a and 30b is linear at least in the pressing area 16a.

  According to the present configuration, when the work members M of the plurality of press forming lines 30a and 30b are simultaneously pressed and formed by the pressing member 14, the plurality of press forming lines 30a and 30b are pressed by the pressing member 14 At the center point 16b of the pressing area 16a to which the pressure is applied, they intersect with each other.

  For this reason, since the workpieces M of the plurality of press forming lines 30a and 30b are simultaneously pressed by one pressing member 14, it is possible to simultaneously produce a plurality of molded articles of different materials and different plate thicknesses.

  In particular, in one aspect of the present disclosure, the plurality of press forming lines 30a and 30b cross each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. Each of 30 a and 30 b is linear in at least the pressing area 16 a of the pressing member 14.

  Therefore, no eccentricity occurs when a pressing force is applied by the pressing member 14. As a result, since the pressing force can be applied uniformly to the workpieces M of the plurality of press forming lines 30a and 30b, the quality of the formed product becomes good in any of the press forming lines 30a and 30b. .

  Furthermore, in the present embodiment, each of the plurality of press forming lines 30a and 30b is linear at least in the pressing area 16a of the pressing member 14, and sterically intersects each other at the center point 16b of the pressing area 16a. There is. As a result, the center of gravity of the pressing force gathers at the intersection of all the press forming lines 30a and 30b regardless of the presence of the missing press forming lines 30a and 30b. As a result, even if a drop occurs in any of the plurality of press forming lines 30a and 30b, it does not affect the press forming line 30a other than the dropped line, for example, the press forming line 30b, and the press is not missing. The molding line 30a can be pressed uniformly and stable production can be performed.

  Therefore, it is possible to provide the press working apparatus 10 that can press without breaking the pressure balance of the pressing member 14 even if a missing line occurs in any of the plurality of press forming lines 30a and 30b.

  In addition, in the present embodiment, the plurality of press forming lines 30a and 30b three-dimensionally intersect with each other at the center point 16b of the pressing area 16a to which the pressing force by the pressing member 14 is applied. This means that the plurality of press forming lines 30a and 30b extend radially, and the distance between the adjacent press forming lines 30a and 30b increases with distance from the center point of the crossover. Means
