摘要： A door hinge assembly is disclosed, which comprises a door hinge assembly for pivotally connecting a door to a fixed structure. The assembly comprises a first wing member secured to the fixed structure, the first wing member having first aligned bores formed therethrough; a second wing member secured to the door, the second wing member having second aligned bores formed therethrough, the first and second wing members being so arranged that all of the first and second aligned bores are aligned; a pivot shaft passing through the aligned first and second bores to pivotally connect the first and second wing members; plastically deformable bushes respectively disposed in the second bores while rotatably receiving therein the pivot shaft; a first structure for suppressing rotation of the pivot shaft relative to the first bores; and a second structure for suppressing rotation of the bushes relative to the second bores. Each bush includes a tubular part intimately and tightly received in the corresponding one of the second bores, and a first flange part integrally formed on one end of the tubular part and intimately contacting with one surface of the second wing member. The bush further includes a slit which extends axially throughout the tubular and flange parts thereby providing the bush with circumferentially opposed terminal end portions.

摘要： A bearing is manufactured by applying an axial pressing force to a cylindrical wound bush and thereby forming a notch-free flange at one end of the bush which is tapered previously. The flange is formed through a kind of plastic flow induced in the tapered end by the force.

摘要： A piston rod is supported free to slide without using a guide bush so that there is no risk of the guide bush falling out. Also, costs are reduced and oil leakage is prevented by eliminating additional procedures such as caulking. The piston rod, which has excellent durability, is allowed to slide smoothly over a long period of time without generating noise. For this purpose, in a bearing unit for a single cylinder type hydraulic damper or gas spring, or a multi-cylinder type hydraulic damper comprising seal members 55, 56, 57 and 64, and a rod guide 6, the rod guide 6 comprises a cylindrical engaging part 13 which engages with a cylinder 2, a cylindrical bearing part 16 which guides a piston rod 5, and a bearing layer 15 fixed to the inner circumferential surface of the cylindrical bearing which slides on the outer surface of the piston rod. The bearing layer is previously fixed only at a position of a base material comprising a thin steel plate which becomes the cylindrical bearing part, and the rod guide is formed in a one-piece construction by press-molding or deep-drawing this base material.

摘要： An useful method of producing a lot of bearings in the form of a press worked bush is initiated with production of blanks having four corner edges chamfered. In the notch forming and cutting die section comprising upper and lower die halves a strip of metallic material that is called hoop is pressed stepwise to form a plurality of V-shaped notches of which depth increases stepwise toward the outlet of the die section. On completion of forming of notches the hoop is cut off at the center of the last V-shaped notch with the aid of a pair of cutting tools. The die assembly usable for carrying out the method includes an U-bending die section and a circle bending die section which are located in series. After leaving the notch forming and cutting die section a blank is introduced into the U-bending die section by utilizing feeding movement of the hoop of the notch forming and cutting die section and thus U-bent blank is subjected to final circular bending in the circle bending die section also by utilizing feeding movement of the hoop. No feeding device is required in each of the press working steps.

摘要翻译： 以冲压加工衬套的形式生产许多轴承的有用方法开始生产具有倒角的四个角边缘的坯料。 在包括上半模和下半模的切口形成和切割模具部分中，称为箍的金属材料条被逐步地压制以形成多个V形凹口，其深度逐渐朝向模具部分的出口增加。 在完成切口成形时，借助于一对切削工具在最后的V形切口的中心处切断箍。 可用于执行该方法的模具组件包括串联设置的U形弯曲模具部分和圆形弯曲模具部分。 在切口切割模切部分离开之后，通过利用凹口形成和切割模具部分的环的进给运动将坯料引入U形弯曲模具部分中，从而使U形弯曲坯料在圆中经受最终的圆形弯曲 弯曲模具部分也通过利用箍的进给运动。 在每个压力加工步骤中不需要进料装置。
