Description

Description: TECHNICAL FIELD The present invention relates to a processing apparatus applied to press working of a sash mold material and the like, and more particularly to high-mix low-volume production excellent in usability for workers. The present invention relates to a suitable processing device.

(Prior Art) A conventional processing apparatus of this type generally comprises a combination of a press machine and a large number of die sets (molds), and sequentially performs processing while appropriately exchanging the die sets according to the mode of processing. . Nowadays, with the diversification of consumers' values and shortening of delivery time, it is not possible to perform the same processing in a large amount as in the past, so it is necessary to change die sets frequently. Has become. It often happens that it is necessary to process two or three mold materials and replace the mold. The die set weighs as much as 30 kg depending on the object, and the labor for exchanging the die set is extremely large, which not only puts a severe burden on the operator, but also has a high possibility of being injured during the exchange work, and further, the productivity is increased. There are various problems such as a decline.

Several devices for solving these problems have been proposed in the past. For example, the apparatus of Japanese Patent Laid-Open No. 58-86941 is equipped with a shelf supporting a large number of die sets on the back of one press machine, and a desired die set is selected from the shelves and pressed by mechanical force. It can be set on the machine. Therefore, this device does not require human power to replace the die set, thus reducing the burden on the operator and reducing the risk of injury.

(Problems to be Solved by the Invention) However, since the apparatus becomes large and complicated, it becomes expensive, and since the entire shelf on which a large number of die sets are moved moves slowly, a press machine is also used. After removing the die set set in and returning it to the prescribed shelf position,
Since it is necessary to select a new die set and set it in the press machine, there are still many problems to be solved such as it takes time to replace the die set.

Therefore, the object of the present invention is to reduce the burden on the operator and change the processing of the mold material in a short time with a simple operation,
Another object of the present invention is to provide a processing apparatus suitable for high-mix low-volume production that can reduce costs.

The position of the press cylinder is fixed by an appropriate fixing means, and the die material is pressed by a desired die. The press cylinder is operated by remote control.

Next, when processing is to be performed by another die, the press cylinder is moved to the installation site of the die by the same operation as above to fix the position. After that, the mold material to be processed is set in a desired mold, and the press cylinder located above the mold is operated to perform the desired mold processing.

That is, when trying to process with a desired mold among a large number of molds arranged side by side on a press mold support shelf arranged in a large number of upper and lower stages, without changing the installation state of each mold, The desired die material can be processed simply by moving the press cylinder above the support shelf, on which the desired die is installed, along the beam to the installation site of the die. Therefore, the operator does not need to replace the mold, which is a heavy load, and simply moves the press cylinder along the beam, so that the desired mold material processing can be easily performed without any dangerous work.

In addition, the press cylinders mounted on the upper and lower sides may be configured to be independently movable.

The chips generated during processing fall downward from the holes made in the support shelf at the bottom of the mold, but a chip receiver is provided in the lower stage of the shelf, and the falling chips are stored in the chip receiver. . According to an exemplary embodiment, the chip receptacle is movable parallel to the support rack, so that the chips in the chip receptacle are expelled accordingly.
