The invention relates to objects, for example bending devices (benders), hydraulic presses, pneumatic fields

The present invention relates to devices for holding dies such as presses, machine-actuated presses, and press forming devices, such as dies and blades, wipers, frames, covers, plates, paintings, walls, partitions, signboards, and pipes such as pipes and tubes.

The present invention relates to a device for holding a drill or an end mill as an object, and more particularly to a device for holding a microdrill used in a high-precision rrc device or the like. BACKGROUND ART Conventionally, as a mold for performing processing such as bending or molding of an object, for example, a metal plate, a punch-shaped upper die and a flat lower die having a bent groove are used. Is placed on the lower mold and pressed by the upper mold into the bent groove of the lower mold, and the upper mold is lowered until the bent portion of the metal plate pressed by the upper mold collides with the bent groove of the lower mold. The metal plate was bent so that the angle of the bending groove of the lower mold and the bending angle of the metal plate were the same.

In this type of mold, since the size and shape of the flat groove of the lower mold are usually limited, dozens of types of flat plates having different sizes and different shapes of the bent grooves are used. Prepare a lower mold and select the type of lower mold each time to fit the lower mold according to the thickness and bending shape of the metal plate to be bent. It was fixed detachably.

To detachably fix the lower mold, remove the screws, bolts, pins, etc., and remove the fixing section of the fixed lower mold from the mounting storage room etc. provided in the holder of the folding device, and then re-install the lower mold. It is necessary to insert the selected lower mold insertion part into the mounting storage room etc. provided in the holder of the bending device and fix it with screws, bolts, pins, etc., which makes the replacement work of the lower mold difficult. (Depending on the thickness and the bent shape of the metal plate to be bent, it is necessary to select the type of upper die and replace the old and new ones. was there).

Also, when defining plate materials such as blades, wipers, frames, covers, plates, lids, walls, partitions, and signboards and pipes such as pipes and tubes on the holder, screws, bolts, pins, etc. As in the case of the mold described above, there are inconveniences such as the necessity of removing and attaching work, which is troublesome and lowers the work efficiency.

When using various substrates used in electronic equipment and high-strength ultra-ultra-fine alloy plates used in precision equipment with high-precision NC equipment, etc., when performing micro-hole processing with high-speed rotating micro drills, accurate Hole position accuracy and hole quality are required.

However, conventional high-speed rotating micro-computers used in the high-precision NC equipment described above! A direct holding means such as a three-way chuck (collet) or an indirect holding means such as a hydraulic chuck mechanism is often used as a holding device for the drill. And the centrifugal force weakens the tightening force of these chucks, making the chucks inadequate and requiring the exact (1) required for various substrates and high-strength ultra-ultrafine alloy plates. There was a defect that it was not possible to achieve hole position accuracy and hole quality. If a three-way chuck is used as the holding device for the micro-drill described above, the micro-drill body that had been fixed by removing the screws, bolts, pins, etc. of the three-way chuck was removed from the three-way chuck, and the newly selected micro-drill was removed. It was necessary to insert the body of the drill into the three-way chuck and attach the screws, bolts, pins, etc. again to define it. This was inconvenient because the replacement work for the microdrill was troublesome and the work efficiency was reduced.

For objects such as bending machines (benders), hydraulic presses, pneumatic presses, machine-operated presses, press forming machines, etc. In each case, a new lower mold (upper mold) having grooves of different sizes and different shapes is selected according to the thickness and bent shape of the lower mold (upper mold). It is necessary to remove it from the mounting storage room etc. provided in the holding body, replace it with another lower die (upper die) and fix it. The objective is to improve the efficiency of processing operations such as bending or molding of metal, etc., with quick and simple operation.

Also, remove pipes such as blades, wipers, frames, covers, plates, sandalwood, walls, partitions, signboards, and other pipes such as pipes and tubes from the mounting chamber of the holder according to the purpose of use and wear, etc. and replace them. However, it is an object of the present invention to improve the work efficiency by exchanging the old and new plate materials and pipe materials with one touch by a quick and simple operation.

Further, according to the present invention, when a new mold and a lower mold (upper mold) are exchanged for a mold which is one of the object holding devices, bolts and the like are provided in a mounting storage room or the like and a lower insertion portion. In other words, the strong pressing force of the upper die when bending or forming a metal plate or the like is concentrated on specific members such as bolts and screws. By receiving over the entire surface of the retainer, etc., these wear, cracks and damage are prevented, The lower die (upper die) is firmly fixed to the mounting storage room, etc., to prevent it from falling off from the lower die (upper die) mounting storage room, etc., and to bend or mold metal plates, etc. The purpose is to sharpen and clean it, and to further improve the processing accuracy.

According to the present invention, in order to hold a drill or an end mill as an object, a slide ball is slidably disposed in a retainer in which a fixed ball is embedded and a storage groove without using a fastening and holding means such as a three-way chuck and a hydraulic chuck mechanism. By fixing the body of the drill or end mill directly to the drilled low-bearing clutch machine, and by firmly holding the body of the drill or end mill with strong tightening force, eliminating the backlash of the drill or end mill. The purpose is to perform accurate centering of a drill or end mill to achieve the accurate hole position accuracy and hole quality required for various substrates and high-strength ultra-ultra-fine alloy plates.

In addition, according to the present invention, since the three-way chuck is not used for holding the drill or the end mill described above, the screw, the bolt, the pin, etc. are removed and the screw, the bolt, the pin, etc. are attached again, and the drill or the end mill is attached. There is no need to fix the body of the end mill, and the exchange of new and old drills or end mills can be performed quickly and simply with a single touch, saving labor for exchanging drills and end mills, The purpose is to improve the working efficiency of processing high strength ultra-ultra-fine alloy sheets and the like.
