The present disclosure relates to a crimping apparatus for a battery cell, and the technical object to be achieved is to provide a crimping apparatus for a battery cell capable of improving the formation quality of a battery cell. To this end, the present disclosure provides a crimping apparatus for a battery cell, which includes a lower jig disposed around a circumference of a battery can, a first upper jig which descends to come into contact with the lower jig above the battery can and presses and moves the lower jig toward the battery can, and a second upper jig which is disposed inside the first upper jig, descends along with the first upper jig, and presses an end portion of the battery can downward to bend the end portion toward a cap assembly.

In an example embodiment, the flange 10 has one or more openings 90 for accommodating fasteners 92 for fastening the flange and tubular member (e.g., for fastening the grab bar) to a structure such as a wall, as for example shown in FIG. 6. In example embodiment as shown in FIGS. 6 and 7, flange covers 94 that extend over the flange 10, so as to cover the flange, may be used. The flange cover may be installed over the tubular member prior to the bucking, or from the opposite end of the tubular member after buckling. As can be understood, if flanges are connected to both ends of the tubular member in accordance with the example embodiment herein, the flange covers must be placed over the tubular member at least prior to the bucking of the second end portion of the tubular member. In an example embodiment, each flange cover has an opening 96 having a diameter larger than the outer surface diameter of the tubular member but smaller than the outer surface diameter of the buckled section of the tubular member. A such, the flange cover can be axially retained by the its corresponding buckled section of the tubular member. If the flange cover opening has a diameter greater than the diameter of the buckled section of the tubular member, the cover will be axially retained by the flange. The flange cover should have an appropriate area to cover its corresponding flange. In the example embodiment shown in FIGS. 6 and 7, the flange cover 94 has a radially extending surface 98 from which extends an axially extending surface 100. With this example embodiment, as shown in FIG. 6, the radially extending surface 98 covers the flange 10, while the axially extending surface 100 surrounds the flange 10.

A tubular member and flange combination includes a tubular member having a buckled section proximate an end of the tubular member. A flange is penetrated by an end of the tubular member where an end section of the tubular member is bent over the flange such that the flange is axially retained by the buckled section and the bent end section of the tubular member. A method of forming the tubular member and flange combination includes buckling the tubular member at a location proximate an end of the tubular member forming a buckled section, placing the flange over the tubular member end section such that the tubular member end section penetrates an opening of the flange, and bending an end section of the tubular member to extend over the flange, such that the flange is axially retained by the buckled section and the bent end section of the tubular member.

A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

A method and a device for obtaining a joint between two surfaces of two parts that have a simple curvature are proposed in which a mandrel is placed below the first surface, which contains a moving stamp in its interior. A template is placed above the second surface, which has a deep drawing opening. The stamp is moved along the surface normals of the two surfaces, such that material forming the two surfaces is forced into the deep drawing opening, wherein the deep drawn and compressed portion of the first surface engages behind the remaining part of the second surface to obtain a form-fit connection between the two surfaces. The stamp blocks a channel inside the mandrel until pressure from a medium therein causes the stamp to move.

A crimping tool is for crimping at least two members together and confirming that the crimp is acceptable. The tool includes a first handle element and a second handle element, a first jaw pivotably coupled to the first handle element and a second jaw pivotably coupled to the second handle element such that the first and second jaws move between open and closed positions responsive to movement of the first and second handle elements, an insert assembly comprising a number of mounting members coupled to at least one of the first and second jaws, and at least one gauge removably coupled to at least one of the number of mounting members.

The present disclosure relates to an apparatus for manufacturing a secondary battery and is directed to providing an apparatus for manufacturing a secondary battery in which a crimping part is formed by bending an end part of a battery can and which has a simple structure and improved operational reliability. To this end, the present disclosure provides an apparatus for manufacturing a secondary battery, which includes: a jig part that moves from an outside of a battery can toward the battery can and presses the battery can to bend inwardly; and a jig pressing part that presses the jig part so that the jig part presses the battery can by moving in a direction intersecting a movement direction of the jig part.

A method of forming a wick using a mandrel is disclosed. The method includes positioning a wick mesh about the mandrel, positioning a sheath about the mandrel and the wick mesh, coupling a first fitting to the mandrel, wherein the first fitting comprises an adapter configured to couple with a source of pressure, and pressurizing the mandrel with the source of pressure to hydraulically expand the mandrel such that that mandrel compresses the wick mesh against the sheath and forms the wick.
