この考案は繰返しせん断エネルギーを利用して
高分子複合材料等に穴明け加工を行う振動穴明け
装置に関する。[Detailed Description of the Invention] This invention relates to a vibratory drilling device that uses repeated shear energy to drill holes in polymer composite materials and the like.
高分子複合材料は繊維質を含むため軽くて強く
て強靭な材料であるが、この材料に穴明け加工を
施すに当り、従来のドリルによつて穴明けする場
合は、あけられた面は積層された繊維質であるた
め、けば立つたり、時には積層された層の境界で
剥離を生ずることもあり、又穴にかえりが出るこ
とは避けられなかつた。ましてブローチなどによ
る多種形状の穴明け加工は殆ど不可能であつた。 Polymer composite materials are light, strong, and tough materials because they contain fibers, but when drilling holes in this material using a conventional drill, the drilled surface is laminated. Because it is made of fibrous material, it becomes fluffy and sometimes peels off at the boundaries of laminated layers, and burrs inevitably form in the holes. Furthermore, it is almost impossible to drill holes in various shapes using a broach or the like.

合、加振ポンチやダイの交換が面倒であるので、
加振ポンチやダイの交換が容易で段取り時間が短
縮でき、しかも装置本体の剛性がすぐれ保全の容
易な構造の穴明け装置が要望される。 In order to solve these problems, it is conceivable to punch the workpiece from above and below, vibrate the punch, and repeatedly apply shearing energy while feeding one side to punch the hole. In this case, it is possible to make a clean hole without burrs with high precision by melting a part of the machined surface due to shear heat caused by repeated shearing and the ironing effect of the outer periphery of the vibrating punch, but it is possible to drill a clean hole without burrs with high precision. When changing the setup by replacing the vibrating punch or die that matches the hole shape, it is troublesome to replace the vibrating punch or die.
There is a need for a hole-drilling device that allows easy replacement of the vibrating punch and die, shortens setup time, has a rigid device body, and is easy to maintain.

ができる。 To drill a hole with the vibratory drilling device of this invention, first, a workpiece 35 such as a polymer composite plate is placed on the lower die 15. Next, the cylinders 28, 28 are operated to press down the upper die 22 and clamp the workpiece 35 between the upper die and the lower die. Next, the torque motor 6 is driven to lower the nut 10 and the workpiece 35 is tightened between the upper vibrating punch 26 and the lower vibrating punch 16. In this state, the vibration device 3 is activated to repeatedly apply a vibration shear load to the workpiece 35, and the vibration device 3 feeds the entire vibrating section upward, thereby drilling a hole in the same shape as the cross-sectional shape of the punch. Can be done. In this way, since the workpiece is cut by repeatedly applying shearing force, the inner surface of the hole is clean and shiny due to the melting of some processed surfaces due to shear heat due to shear heat, and the ironing effect of the outer peripheral surface of the vibrating punch, with less burr. It is possible to perform precise hole machining. When replacing the vibration punch or die, tighten the bolt 20 to fix the lower vibration punch to the lower die 15, then loosen the bolt 13 and pin 14 and remove the bracket 12 from the main body 1. It is sufficient to replace the upper and lower vibration punches 26 and 16 and attach them to the main body 1 again. If you have a spare bracket, you can replace it faster by installing the punch and die in advance.

ができる。 In this invention, as mentioned above, the upper and lower dies and the upper and lower vibrating punches are built into the bracket, so the entire bracket can be replaced together, and the setup time can be significantly shortened. Furthermore, since the device main body 1 is box-shaped, it has high rigidity and improves the accuracy of hole machining of the workpiece. Furthermore, since the cylinder 28 for holding the workpiece is mounted outside, many excellent effects such as easy maintenance can be achieved.
