Description

[Detailed Description of the Invention] This invention is based on the punch press machine installed in parallel and the sheet metal tX? υ of the sheet metal, which performs IJO processing on the sheet metal in order using the punch press machine and shearing machine.
Regarding the Loe system.

A bunch brace machine and a shearing machine are installed side by side.
First, punch holes in the sheet metal using a punch press machine.
There are the following problems with the continuous shelf line, in which the 10 pieces of sheet metal are sent to a shearing machine, and the shearing machine cuts them into the respective product dimensions.

In other words, when trying to obtain a product by drilling/JD machining a large number of holes on a relatively large sheet metal surface from a single material sheet metal, it is necessary to perform IJD machining that takes a longer time than IJD machining. When trying to obtain a large number of small-area product sheet metals with a relatively small number of holes and holes from a single material sheet metal, the cutting IJII process will take a longer time than the drilling IJO process.

When trying to obtain a predetermined Itagasa product from a sheet metal material with a continuous 0 line as described above, it is rare that the raw material specifications of the sheet metal material are the same, and usually each material &
Every gold or several pieces.

The IJO specifications differ depending on the sheet metal material, and in this case, the following inconveniences occur.

That is, for example, the U11 process of the first sheet metal material is completed in a short time for both the drilling process and cutting IJD process, while the process of drilling the second sheet metal requires a longer time than the cutting process. If it is, the first hole υ
Even if the second sheet metal is sent to the punch press machine immediately after finishing the rowing process, the shearing machine finishes cutting the first sheet metal before completing the punching process for the second sheet metal. There may be inconveniences such as waiting time on the shearing machine side, or if the timing of feeding the second material sheet metal to the punch press machine is too early or too late. The drilling of the second sheet metal was completed even though it was not finished, so I had to leave the sheet metal that had been drilled for the second sheet on the punch press machine. , the punch press machine becomes unable to start processing the third sheet, or
If it was too late, even if the cutting of the first sheet had already been completed, the drilling of the second sheet would not have been completed, resulting in an inconvenience such as waiting time on the shearing machine side. . The timing for feeding the second sheet metal to the punch press machine is the timing at which the second sheet metal is punched.
If you do not accurately set the 11th hour and the cutting time of the first sheet metal and execute it correctly, you will not be able to send it in at the right time, but it is difficult to accurately set and execute the 811th time. Inevitably, the timing will be off and waiting time will occur in either the punch press machine or the shearing machine, and even if the waiting time is small for one sheet metal sheet, if the number of sheets is multiple stitches, the total required time for υroe will be reduced. was significantly increased and the efficiency was significantly decreased.

Therefore, the present invention aims to solve the above-mentioned disadvantages of the continuous IJli line and provide an efficient &gold QD system.
