摘要： There is provided an insert nut, having an outer hollow portion made of a resin material and an inner hollow portion made of a metal material. The outer hollow portion has a projection functioning as a male screw or wedge formed on an outer surface thereof. The inner hollow portion has a female screw formed on an inner surface thereof. The inner hollow portion is press-fitted to the outer hollow portion by inserting one end of the inner hollow portion into the outer hollow portion to reach a final position. Further insertion of the inner hollow portion is prevented beyond the final position. Said one end of the inner hollow portion is caulked with the outer hollow portion.

摘要： A metallic fastening member of a one piece configuration formed of a metal material includes a shaft and a flange extending outwards from a first end of the shaft. The shaft includes a relatively thin-walled portion to be caulked at a second end opposite to the first end. A female threading is formed at an inner peripheral face of the shaft excluding the portion to be caulked. An annular groove is formed at an outer peripheral face of the shaft or at the inner peripheral face of the portion to be caulked, so that the shaft has a partially thin wall. Since the wall of the shaft is thinner at the annular groove, the metallic fastening member can be fractured at that area so as to be separated into upper and lower pieces when detaching the metallic fastening member from a workpiece. Therefore, the metallic fastening member can be readily removed from the workpiece to facilitate the recovery work for recycling purposes.
摘要翻译：由金属材料形成的单件构造的金属紧固构件包括轴和从轴的第一端向外延伸的凸缘。该轴包括相对薄壁的部分，在与第一端相对的第二端处被铆接。在除了要被铆接的部分之外的轴的内周面处形成有内螺纹。在轴的外周面或被铆接部的内周面形成环状槽，使轴具有局部薄壁。由于轴的壁在环形槽处较薄，所以金属紧固构件可以在该区域处断裂，以便在将金属紧固构件从工件上拆下时被分离成上部和下部部件。因此，金属紧固构件可以容易地从工件移除，以便回收工作用于回收目的。

摘要： In a method of working a metal member, a liquid synthetic detergent mainly composed of a surface-active agent is supplied to a metal plate as a lubricant in a press working step of holding the metal plate between a male die and a female die and press-forming the same. According to this working method, press working of a stainless steel plate or the like can be smoothly performed due to excellent lubricity of the surface-active agent contained as the main component in the liquid synthetic detergent. When a lubricant prepared from a liquid synthetic detergent containing a rust preventive is applied to lubrication of a carbon steel plate or the like, excellent workability can be attained without rusting, due to the action of the rust preventive, and with no contamination by oil.

摘要： In order to manufacturer a tee nut by plastic working steps, a swollen portion is formed on a metal plate, a through hole is formed in the forward end surface of this swollen portion, and then the outer diameter and therewith the wall thickness of a forward end portion of the swollen portion is relatively reduced as compared to a base portion of the swollen portion. Then, the outer and inner diameters of the base portion are reduced while substantially maintaining its wall thickness. Thus, the forward end portion defines a relatively thin portion to be caulked, and the base portion defines a relatively thick female screw forming portion of the tee nut. Thus, it is possible to form a tee nut having a shaft with a uniform outer diameter and having a relatively thin forward end portion forming the portion to be caulked while the tee nut is held by the metal plate.
摘要翻译：为了通过塑性加工步骤制造三通螺母，在金属板上形成膨胀部分，在该膨胀部分的前端表面形成通孔，然后形成一个向前的外径和壁厚与膨胀部的基部相比，膨胀部的端部相对减少。然后，基本部分的外径和内径减小，同时基本保持其壁厚。因此，前端部限定相对薄的待铆接的部分，并且基部限定了三通螺母的相对较厚的内螺纹形成部分。因此，可以形成具有均匀外径的轴的三通螺母，并且在三通螺母被金属板保持的同时具有形成待铆接部分的相对较薄的前端部。

摘要： Disclosed herein is a Tee nut which can form a hole in a work piece with no problem by driving of the Tee nut itself, without previously forming a hole in the work piece. A closure member is engaged in a hollow shaft portion, to divide a portion to be caulked from a female threading carrier portion. A punched-out portion resulting from a hole which is formed by driving of a Tee nut itself is prevented by the closure member from reaching the female threading carrier portion, so that the punched-out portion can be discharged at the same time by extruding the closure member.

摘要： A tee nut is integrally made of a metallic material to have a shaft portion and a flange portion, the latter having two pairs of pawls projecting in the direction in which the shaft portion extends. The pawls are disposed radially of the flange portion. The peripheral edge of the flange portion is formed with projections at position diametrically opposed to each other and at right angles with the radial direction in which the two pairs of pawls are opposed to each other. The projections extend in the same direction as that in which the pawls extend namely toward the free end of the shaft-portion. The clearances in guide rails of C-shaped cross-section constituting a feed track, are substantially decreased in size by the presence of the pointer projections producing a decreased frictional resistance between the track and nuts travelling on the track overlapping of the flange portions due to the rise of the flange portions in the guide rails is prevented, thus ensuring a smooth movement of the tee nut along the feed track.
摘要翻译：三通螺母由金属材料一体制成，具有轴部分和凸缘部分，后者具有沿着轴部分延伸的方向突出的两对棘爪。棘爪在凸缘部分的径向设置。凸缘部分的周缘在彼此直径相对的位置处形成有与两对爪彼此相对的径向方向成直角的位置处的突起。突起沿与棘爪延伸的方向相同的方向延伸，即朝向轴部的自由端。构成进给轨道的C形横截面的导轨间隙由于存在指示器凸起而在尺寸上显着减小，该指示器凸起导致在由于凸缘部分的轨道重叠而行进的轨道和螺母之间的摩擦阻力减小防止导轨中的凸缘部分的上升，从而确保三通螺母沿着进给轨道的平稳移动。
