Field of the Invention The present invention relates to a container for sliding along the inner wall of a container constituting a functional product such as a cylinder or a shock absorber and supporting a member protruding from an open end of the container. The present invention relates to a method, an apparatus, and an apparatus for integrally forming a metal fitting for retaining a bearing provided with means for preventing the bearing from falling off, which is inserted into at least one of the metal fittings for closing the open end of the bearing.

Description of the Related Art In order to manufacture a metal fitting for closing an open end of a container, it is old to form a metal mold with a sintered alloy, and then cut a fitting part or a joint part with other parts to be mounted inside and outside with a cutting tool or the like. Currently, most of the metal fittings are formed by pressing using a sheet metal material, but only the fitting part for press-fitting the bearing is still shaped by cutting with a blade. Is done.

得ない。In order to manufacture a low-cost component, it is preferable to take a break in the entire processing from a sheet metal material such as steel, stainless steel, clad steel or the like to a finished product. In this case, it is difficult to maintain continuity when processes having different processing contents coexist.

し、部品の機能を失うことがしばしば起こる。[0004] In the case of a component that requires a bearing made of a material such as metal or non-metal to be inserted into a fitting for closing the open end of the container, it is necessary that the bearing does not move from a predetermined position during use. However, when the force acting on the bearing is static, it can be dealt with only by press-fitting the bearing into the metal fitting, but to this extent, it cannot respond to a dynamic force (particularly a shocking force). Often, the bearing easily falls out of position and loses part functionality.

は非連続と成らざるを得なかった。[0005] Therefore, the fixing of the bearing requires a sufficient stopper other than crimping. However, since the press cannot be formed to a required height, a cutting step using a cutting tool is necessary for forming this portion. However, as compared with a pressing process in which a forming process is performed by applying a force, the type and shape of a machine used in the cutting process are greatly different, and it is difficult to directly connect the two processes, so that the process has to be discontinuous.

も早く解決すべき課題である。In the case of a non-continuous process, an increase in the number of workers due to a difference in the contents of work and ineffective time spent in setup and standby is inevitable, which inevitably becomes a major obstacle to cost reduction, and in particular, competition. In the fierce vehicle industry, there is a strong demand for lowering the price of parts, and this is an issue to be solved as soon as possible for the manufacturing industry of functional products such as shock absorbers, which markets the industry.

The small protrusion is also formed in the step described in [0008], but the two molds used in this step are large except that the tip shapes of the upper and lower molds are different.

となり良好な抜け止めを成形出来る。The application of the retaining process according to the present invention to a semi-finished product (hereinafter referred to as a "processed material") in which the shape of the processed material has been changed by various processes is preferably a final process step of the processed material. In this state, when the retaining die and the working material are combined, play between the two is minimized, and a good retaining can be formed.

工の際に傷つけることはない。The retaining mold used for retaining is composed of upper and lower dies in which at least two layers of pressing dies are concentrically closely fitted, fitted and arranged, and corresponding upper and lower dies. The combined stamping tool is in close contact with the inner and outer shapes of the processing material, and only the necessary portion of the processing material is squeezed out from the starting point of the die so as to scrape off the die with the die. Since it is configured to be completed, the already processed end portion of the processing material and the inner and outer fitting portions are not damaged during the retaining process.

記嵌合部分に連接する非嵌合部分が主な対象になる。The shape of the stopper provided at the fitting portion of the metal fitting with the bearing is often a protrusion having a cross section close to a substantially quadrangular shape along the inner periphery (see FIGS. 1A and 1B). In some cases, a sufficient effect can be obtained with at least one small projection along the inner circumference, and FIG. 2 (A, B) shows four cases. In this case, the portion to be shaved off is mainly the non-fitting portion connected to the fitting portion, which is the mounting position of the bearing.

は三角形状になる。When the retaining member is intended for a projection having an annular shape and a quadrilateral cross section, the tips of the upper and lower inner stamping dies, which are constituents of the mold used, are flat, and in particular, the tip of the upper inner stamping die is formed. Providing a step portion having a slightly smaller outer diameter as a concentric circle facilitates transmission of molding force to the processing material, and at the end point of molding, the tips maintain a small gap corresponding to the axial thickness of the projection, thereby forming an annular shape. A projection having a quadrangular cross section can be formed by forming a small step with a diameter corresponding to the inner diameter of the stopper at the upper inner press die tip side portion of the minute gap and thinner than the thickness of the stopper. Often, in the case of small projections, the lower inner press die is provided with claws corresponding to the width of the projections. At the end point of the molding, if a slightly wider gap is provided without contacting the tips, the projection cross section becomes triangular.

However, since the upper and lower dies are each constituted by at least two layers of pressing dies, especially the bearing is used. It is preferable that the inner press die of either one of the molds forming the mounting portion of the lower die is a single movable type having a fine adjustment function, and from the viewpoint of removing / cleaning and handling falling objects, the tip shape of the lower die is preferable. Is preferably convex.

Even if a strong force acts, the built-in bearing is prevented from falling off, so that the function of the component to which the metal fitting is attached is not impaired.

It is not preferable to make the gap narrow as described above, because the molded portion swells beyond the width of the claw 43B and the shape of the retaining member collapses and weakens. Also, if the height h of the claw 43B is sufficiently taken, there is no risk of damaging the surface of a portion that does not require processing during molding, and the number of small protrusions can be arbitrarily selected by increasing or decreasing the number of claw. .

Pressing can be used to form the retaining part, eliminating the need for a different type of cutting machine that had to be used in the conventional method. . The knitting of the continuous machining process has enabled a significant reduction in machining costs that could not be achieved by the conventional method. The precision of the metal fittings for retaining bearings produced in a continuous processing process using only a press was not inferior in quality to products manufactured by a conventional method using cutting. Since the metal fitting is constituted by a plurality of pressing dies stacked concentrically, it is easy to process the tip of the pressing dies to the shape of the work material.

The combinations of (0, 25) correspond to each other, and when the tips of the inner press dies (18, 23, 43) are closest to each other, a slight gap is secured and they do not come into contact with each other. The inner die end (18A) of the upper die (16) is cut as a concentric circle with a diameter less the thickness of the processing material to form a body (18B) and a step (18C), thereby reliably capturing the processing material. The shape is such that the molding force is transmitted to the end face of the same material.
The corner portion of (A) receives the molding force and forms the working material. At this time, the middle pressing die (19, 24) and the outer pressing die are formed so that the forming force is sufficiently transmitted to the processing material. 4. The device for integrally forming a metal fitting with retaining for a bearing according to claim 3, wherein (20, 25) is finished so as to conform to a shape of an already formed portion of the processing material to be contacted.
