DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is applicable to a progressive processing device, particularly for performing punching, bending, drawing, etc. on a strip-shaped workpiece that is sequentially transferred at a predetermined feed pitch. The present invention relates to a progressive processing device that is equipped with a plurality of processing means for sequentially performing a plurality of processing steps, and is capable of improving the precision of processing positions in each of the processing steps.

[Conventional technology]

Conventionally, progressive processing equipment has been used to manufacture sheet metal products of a predetermined shape by successively performing multiple processing steps such as punching, bending, drawing, and compression on a steel strip fed at a predetermined pitch. Are known.

FIG. 17 is an explanatory diagram showing an example of a conventional progressive processing device, which processes a bowl-shaped sheet metal product. Although FIG. 17 is a cross-sectional view, hatching is omitted and the illustration is shown in a slightly simplified manner for ease of understanding.

In FIG. 17, reference numeral IO indicates a block type, which is composed of an upper die 10a and a lower die Job.For example, the upper die 10a is attached to a press ram (not shown) via a shank 11,
The lower die 10b is attached to a positioning and fixing plate (not shown) on the press table. In addition, the block type 10 has
In order from the left, a punch 12a, a punch die 12b, a cutting bunch 13a, and a cutting die 13b.

First to fourth drawing dies 14a to 17a and punches 14b to 17b, first and second shaping dies 18a and 19a and punches 18b and 19b, and edge cutting die 20a and punch 20b are provided. ing.

Note that these punches and dies are each attached to an upper mold holder 21.
a and the lower die holder 21b at a predetermined interval.

With the above configuration, if a workpiece such as a steel band is fed from the left between the punch and die at equal pitches, the punch and die sequentially perform processing such as punching, bending, drawing, etc. For example, a bowl-shaped or cap-shaped sheet metal product can be obtained.

FIG. 18 and FIG. 19 are a plan view and a front view, respectively, showing the processing state of the workpiece. In both figures, workpiece 3
0 is sent in order from left to right at an equal pitch P, and a pilot hole 40 is punched by a punch 12a and a punch die 12b shown in FIG. The workpiece is positioned on each stage by engagement with the provided pilot guide (not shown). Next, numerals 41 to 48 each indicate a stage, and each stage has an interval between the feed of the workpiece 30 and the pitch P. These stages will be briefly explained with reference to FIG. 17 as well.

First, in the stage 41, an arcuate cut having a diameter larger than the outer dimensions of the cap-shaped sheet metal product is made in the workpiece 30 using the cut punch 13a and the cut die 13b. Thereafter, the stages 42 to 45 are moved by intermittently moving the workpiece 30 to the right by successive pitches P.
First to fourth drawing processes are performed using dies 14a to 17a for first to fourth drawings, respectively, and punches 14b to 17b, respectively. After the above-mentioned incision processing and drawing processing are completed, the first and second shaping dies 18a, 19a and the punch 18 are moved to stage 46.47.
b19b, the first and second shaping operations are performed, respectively, to complete the processing of the inner and outer shapes. Next, in stage 4, the outer dimensions are finally regulated by the edge-cutting die 20a and the punch 20b, and the cap-shaped sheet metal product 39 is separated from the workpiece 30 to complete the processing. In addition, in each of the above stages, in order to prevent wrinkles from occurring in the workpiece 30 due to drawing and shaping, the block die 10 is equipped with wrinkle suppressing means and knockout means (not shown) for each stage. (omitted) is provided.

[Problem to be solved by the invention]

Although the conventional progressive processing apparatus described above has the advantage of high production speed and is suitable for mass production of sheet metal products of a predetermined shape, it has the following problems. That is,
Since multiple pairs of punches and dies are incorporated into one mold, the mold structure becomes extremely complex, requiring high-precision mold manufacturing technology, prolonging the manufacturing period, and increasing manufacturing costs. It will become bulky. Further, when repairing a partially damaged mold, it is necessary to disassemble the entire mold, which is extremely complicated and requires a large amount of time and man-hours. Furthermore, in the case of high-mix, low-volume production, if a dedicated mold is manufactured for each different shape of the workpiece, the mold cost will be relatively high.
There is a problem in that it is not possible to meet the so-called FMS production method, which has been increasingly demanded in recent years.

The inventors of the present application have solved the problems existing in the above-mentioned prior art, and have developed a progressive processing device as shown in FIGS. , was proposed in a patent application dated December 1, 1988 (Japanese Patent Application No. 63-304694). Note that FIG. 11 showing the configuration of the proposed progressive processing device is a front view of the main part, and FIG. 12 is a plan view of the main part.

As shown in FIGS. 11 and 12, the progressive processing device proposed above first places a pilot processing means 50 for drilling pilot holes on a press table 31 in which two T-grooves 32 are formed. Set using the two T-grooves 32 mentioned above. Next, a pilot guide means 60 is set at a distance P from the pilot machining means 50 to engage with the pilot hole to correct the machining position of the workpiece. Note that the above P is a feed pinch of a workpiece (not shown) that is fed from right to left. Further, the first processing means 70 is located at a distance of 2.5P from the pilot processing means 50, the second processing means 80 is located at a distance of 4.5P, and the second processing means 80 is located at a distance of 6P from the pilot processing means 50.
a second pilot guide means 60 at a distance of 7.5
A third processing means 90 is disposed at a distance of P, and a fourth processing means 100 is disposed at a distance of 9.5P. In addition, code 3
3 is a mounting bold, and 34 is a spacer.

The spacer 34 is configured to be fixed to the lower surface of the press ram 35 in a position corresponding to the position of the pilot processing means 50 to the fourth processing means 100.

For example, by feeding the steel strip at equal pitches from the right side into the progressive processing device having the above-mentioned configuration and operating the press ram 35, the steel strip is processed as shown in FIG. A bowl-shaped or cap-shaped sheet metal product can be obtained.

Fig. 13 is a plan view showing the machining state of the workpiece material Fig. 14 (
a), (b), and (c) are diagrams showing the longitudinal cross-sectional shape of the workpiece at each stage in FIG. 13, and the positional relationship with FIG. 11 and FIG. 12 is shown for ease of understanding. They are shown in correspondence.

11 to 14, the workpiece 30 is fed sequentially from right to left at an equal pitch P, and first, the pilot hole 40 is drilled by the pilot machining means 50. When the movement is made by the pitch P, the next pilot hole 40 is drilled, and the pilot pin (not shown) of the pilot guide means 60 engages with the pilot hole 40 that has already been drilled, thereby positioning the workpiece 30. It will be done. Therefore, even if there is some error in the feed distance, it is corrected by the pilot guide means 60. Further, when it moves by the pitch P, it reaches the stage 41, where the first processing means 70 processes the arcuate cut 70a.

Next, when reaching the stage 43 via the idle stage 42, drawing processing is performed by the second processing means 80, and the first
As shown in FIG. 4(a), a bowl-shaped protrusion 80 is formed on the workpiece 30.
a, the arc-shaped cut 70a widens its width and changes into an arc-shaped groove 70b. Next, when you reach stage 46 via idle stage 44 and 45,
The third processing means 90 processes a flange hole 90a (shown in FIG. 14(b)). Furthermore, Idol Stage 4
At the stage 48, the fourth processing means 100 forms a bowl-shaped sheet metal product 100a (FIG. 14(c)).
The edge cutting process is performed with the external dimensions shown in the figure), and the process is completed.

The proposed progressive processing device described above aims to improve the arrangement means such as a plurality of independent processing means arranged on the base plate, for example, changing the processing contents, changing the process, changing the processing order, etc. Replacement of the above processing means due to changes in
This makes it possible to improve work efficiency regarding movement, etc. - Furthermore, in order to improve the precision of the product, a pilot processing means 50 and a pilot guide means 60 are provided to improve the precision of the processing position at each stage with respect to the workpiece 30.

However, the accuracy of the machining position can only be improved if the installation position of each processing means, especially the installation position of the pilot guide means 60 that performs positioning correction, is made accurate in accordance with the feed pitch P of the workpiece 30. be able to.

However, for example, when the distance between the pilot processing means 50 and the pilot guide means 60 is (P±α) with respect to the feed pitch P of the workpiece 30, the difference α
A problem arises in that the error is gradually expanded as the error is added for each pinch feed. The manner in which the error occurs will be specifically explained with reference to FIGS. 15 and 16. Note that the distance between the pilot processing means 50 and the pilot guide means 60 does not necessarily match the 1-pitch feed iiP, but is set to nP (n is a positive integer) in accordance with the size of the product. Sometimes. Moreover, in FIGS. 15 and 16, the distance between the pilot processing means 50 and the pilot guide means 60 should be 3P, but due to an installation error, the distance is 3P. This shows how errors occur in the case of IP. (A) is the pilot processing means 5
0 installation position, (B) is the pilot guide means 60
represents the installation position. In addition, Fig. 15 shows the workpiece 3
When the feed amount of 0 is exactly P, FIG. 16 shows a case where there is an error in the feed amount of the workpiece 30. In FIG. 15, the first pilot hole (2) is drilled at time T, one-pitch feeding is performed between time T1 and T, and the second pilot hole (2) is drilled at time T. Furthermore, one pitch feed is performed between time T and ~T, and time T
, a third pilot hole ■ is drilled in . Since the pitch feed amount during this period is exactly IP, the distance between pilot holes 0 to 0 and pilot holes ■ to ■ is IP, respectively. The fourth pilot hole (2) is drilled at time T4 while the pilot hole (2) is pilot guided by the pilot guide means 60. At this time, since the distance between the pilot processing means 50 and the pilot guide means 60 is 3 IP,
The pitch feed amount performed between the above times T and T4 is substantially 1. Since it is an IP, the distance between the pilot holes ■ and ■ is 1. It is an IP. Thereafter, in the same manner, the pilot hole ■ is opened every l pitch feed.

(2), ... are performed, and pilot guiding is performed every three pitches.

As is clear from FIG. 15, the distance between the pilot processing means 50 and the pilot guide means 60 should be 3P. Since it is an IP, the error is 0.
The IP is added every 3 pinch feeds, and the error is gradually expanded.

The example shown in FIG. 16 is basically the same as the example shown in FIG. 15, except that the distance between the pilot processing means 50 and the biloft guide means 60 should be 3P. Since it is an IP, the error is 0. The IP is added every three pitches, and the error is gradually expanded. In the example shown in FIG. 16, there is an error in the pinch feed amount P, and the pitch feed amount performed between times T1 and T2 is 1.2P, and the pitch feed amount performed between times T2 and T3 is 0. .9P.

As explained above, in order to improve the accuracy of products manufactured by a progressive processing device, it is important to make the distance between the pilot processing means and the pilot guide means accurate, as well as the arrangement of each other processing means. Improving positional accuracy is desired.

The present invention has been made in view of the above-mentioned demands, and by improving the positional accuracy of pilot machining means, pilot guide means, other machining means, etc. in a progressive machining device, it is possible to The purpose of the present invention is to provide a progressive processing device that improves the accuracy of processing positions at each stage of the process and makes it possible to manufacture highly accurate products.
