Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tool management method for a heading forming machine.

By the way, the heading molding machine V for manufacturing darts, nuts, and 11 parts each uses various tools such as molds such as punches and gouers, knockout pins, and holders and spacers for these. used. However, these tools are required for each heading stage, so in a molding machine with a large number of heading stages, a large number of tools are used depending on the number of stages.

However, as for the above-mentioned tools, special tools must be used depending on the size and shape of the forged product to be manufactured. Therefore, when changing the setup when switching to manufacturing a different forged product, it takes a considerable amount of time just to assemble a large number of these various types of tools, and there is a high risk of mixing them up during the process. It takes a lot of effort to organize and store tools that are not used.

On the other hand, among such tools, the usage conditions for molds such as punches and dies are severe, so it is important to manage their lifespans, and they must be replaced immediately after they have been used up to the set lifespan.

This will lead to the production of defective products. However, the set life of each mold differs from one another, and for example, the lifespan of the die can also be shortened depending on which heading stage the mold is used at. Therefore, in managing the lifespan of tools such as the above-mentioned molds, it is necessary to accumulate and display the past elapsed lifespan of each tool, which also requires a great deal of effort.

Therefore, in order to deal with such conventional problems, the present invention aims to provide a tool management method that makes it easy to arrange and organize and store a complete set of tools necessary for manufacturing a desired forged product. It is something to do. Another object of the present invention is to provide a tool management method in which the set life and cumulative elapsed life of each tool that requires life management can be easily displayed.

The method of the present invention is provided for this purpose.

Manufacture for each type of desired heading product (a set of necessary tools is prepared in advance and stored in a dedicated tool tray, and multiple such sail trays are placed on a turntable on the heading machine) It is characterized by
Furthermore, the present invention provides a tool tray in which a cartridge-shaped worker life display block having two or more individual display functions is housed in each of the above-mentioned tool trays together with the above-mentioned set of tools, and the tool tray is moved to the lid at the optimum position for use. When a set of tools is taken out from the machine and installed in a predetermined place on the heading forming machine, a tool life display block is also taken out at the same time and loaded into a tool life recording unit on the control table of the forming machine. . DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments shown in the drawings.

First, in the diagram wIJ1, 1 is a heading molding machine with two or more heading stages (5 stages in the example shown), and 2 is a control console for this. The die pace 3 and the nozzle/child base 41 of such a heading forming machine 1

Tool life display blocks B, B, dedicated to each of '...
The tool life recording unit )0, which is shared by each of these display blocks, is installed on the control console 2.

However, the above tool life display block 1. As shown in FIG. 2, Bl, .
It is assumed that a function is provided to individually display the set life and cumulative elapsed life for each tool. That is, the display block HI in the illustrated example has a maximum of 10 individual display functions, and therefore a total of 10 vertical slits 9 are arranged in parallel on its cylindrical surface, and the forging operation of the forging machine 1 is arranged in parallel. A scale lO for indicating the tool life expressed in number of times is written in five columns so that each of the 902 slits serves the same purpose. Each of these slits 9 is provided with a set lifespan indicator piece 11 and an accumulated elapsed lifespan indicator piece 12 located below it so as to be movable individually along the length direction lc of the slit. A total of 10 setting life indicator pieces 11 provided in each of the slits 9 are each provided with a releasable fixing means for individually fixing them to an arbitrary position, and a total of 10 pieces of the set life indicator pieces 11 are also provided. It is assumed that each of the cumulative elapsed life indicator pieces 12 is provided with a mechanism built into the block to individually move them. Also, other display blocks H,,B,
, . . . is also the display block B above.

is configured in exactly the same way.

On the other hand, in recording unit 0, each display block B,...
It has a block insertion hole 13 on the top surface into which either Bl or - is inserted in a replaceable manner, and therein is a drive mechanism for individually operating each moving mechanism of the cumulative elapsed life indicator piece 12 described above. , the same number of indicator pieces 12 are stored.

Each of these drive mechanisms is configured to move the cumulative elapsed life indicator piece 12 according to the number of forging operations of the forging machine 1 based on a preset ratio, and to operate each of the above-mentioned moving mechanisms. Assume that the setting ratio is
Therefore, in order to make it possible to select 100 units of scale for each indicator piece 12, in the example in Figure 1, the front upper surface of the upper knit is 10 rows on the left and right, ! ! 1g The pin pin 14 is made up of three rows of pinholes, and a total of 10 selection pins 15 are prepared for each row of the pin holes. Scale unit is 10,000 times, 10
There are three options to choose from: 10,000 times and 1 million times.

In addition, 16 in FIG. 1 is a tool stocker that is attached to the side of the heading forming machine 1 as necessary, and 5 is a tool stocker that is attached to the side of the heading forming machine 1, for example.
K) Leh81. Eh,... Two or more can be stored three-dimensionally.

In the above configuration, the tools necessary to manufacture the desired heading product are in the tool tray 8. If the tray is stored in the head-forming machine 10, turn the turntable 7 to move the tray to the optimum position for use as shown in FIG. The tool life display block B+ is also taken out and loaded into the tool life recording unit 0 at the same time. Therefore, the tool tray 8I becomes empty as shown. When switching from this state to manufacturing a different forged product, first remove the tool set 1 installed in the forging machine 1 and neatly store it in the tool tray 8I, and at the same time remove the tool life display block BL. After the tool life recording unit C is removed and placed in the tray, it is rotated on the turntable to move the tool tray containing a set of tools necessary for manufacturing the first product to the optimum position for use.

However, there are multiple units (four in the example) on the turntable.
Since the tool trays 81, 8t, . If the number of trays is accommodated, a plurality of types (four types in the illustrated example) of forged products corresponding to the number of trays can be manufactured using only those tools.

In addition, when attempting to manufacture a pressed product that cannot be manufactured using the tools stored in any of the tool trays on the turntable, other tools containing the set of tools necessary for manufacturing this product may be manufactured. All you have to do is prepare a separate tool tray and replace it with one of the tool trays on the turntable. At this time, the tool tray removed from the table can be placed in the tool stocker with the set of tools still stored in it. It is stored in 16.

On the other hand, each of the slits 9 provided on the front side of the tool life display block is for each tool that requires life management among the set of tools combined in the block, for example, a plurality of tools prepared for each FE manufacturing stage. When these tools are new, they are made to correspond individually to each of the die 5 and the buff-chiro in advance.

The set life indicator piece 11 of each corresponding slit 9 is moved to a position where the set life of the tool is indicated and fixed, and the cumulative elapsed life indicator piece 12 is returned to the zero position.

Insert the display block B, for example, into the recording unit 1-00 insertion hole 13 as shown in FIG. , the heading molding machine 1 is operated. Then, the cumulative elapsed life indicator piece 12 of each slit 9 moves according to the set ratio selected by the select pin 15 in accordance with the elapsed life of the corresponding tool, that is, the number of forging operations of the forging machine. Therefore, the elapsed life of the tool is indicated on the scale 1o, and even if the block is removed from the recording unit C when the production of the corresponding forged product is completed, this display will remain as it is. When this display block B is used again when manufacturing the same product for the first time, the current movement amount of the indicator piece 12 is added to the previous movement amount. That is, the elapsed life of the tool each time it is used is cumulatively recorded from the beginning and displayed by the indicator piece 12. Therefore, to give an example in FIG. 2, both indicator pieces 11.1 in the left end slit 9Ic of 1 display block B.
2 indicates that the set life of the tool corresponding to the slit is 9 million times, and the cumulative elapsed life is 6 million times, respectively.

As described above, the present invention applies to each type of forged product.

A complete set of tools necessary for manufacturing this is prepared in advance and stored in a special tool tray in an orderly manner, and a plurality of such tool trays are placed on a turntable on the heading molding machine, and the necessary tools are rotated by the table. Since the set can be moved to the optimum position for use, according to the present invention, it is possible to prepare a large number of different sets of tools necessary for manufacturing a desired forged product each time they are used. This eliminates the troublesome steps required, eliminates the risk of mix-up, and simplifies the steps and time required for changeover when switching to manufacturing different types of products. It can be expected to have effects such as making it easier to organize and store tools that are not used. Furthermore, the present invention provides a cartridge-shaped tool life display block for each set of tools, which is equipped with a function of individually displaying the set life and accumulated elapsed life of two or more tools. 5. When any set of tools is taken out and used, the above-mentioned display block that comes with it is loaded into the tool life 1 sickle unit prepared in the heading molding machine. Therefore, according to the present invention, it is possible to recognize at a glance the cumulative elapsed life of each tool that requires life management, and each tool has a different set life. Therefore, it is possible to easily and accurately calculate the remaining life and determine when to replace a tool, and it is expected to have effects such as eliminating the need for cumulative display of elapsed life.
