A method for manufacturing a joint structure formed by joining a first plate-shaped member and a second plate-shaped member having a shape that is longer in a longitudinal direction than in a lateral direction includes overlapping the first plate-shaped member and the second plate-shaped member, after the overlapping, joining each of both edge portions of the second plate-shaped member by forming a weld metal along the longitudinal direction to the first plate-shaped member. The weld metal extends further outward in the lateral direction than the edge portions of the second plate-shaped member, in which the weld metal is formed by a hybrid welding in which a laser is added as a heat source during arc welding such that the weld metal extends around both of the edge portions of the second plate-shaped member along the longitudinal direction.

A multi-station rotating terminal crimping machine head is provided, the multi-station rotating terminal crimping machine head includes a machine table, a supporting device, a punching head, a rotating seat, a plurality of station seats, a first driving motor, and a first right-angle speed reducer. The supporting device is fixedly disposed on the machine table. The punching head is disposed on the supporting device. The rotating seat is rotatably disposed on the machine table. The plurality of the station seats are disposed on the rotating seat and rotate along with the rotating seat. The first driving motor and the first right-angle speed reducer are disposed on the machine table.

A method of forming a refrigerator cabinet includes a step where an external wrapper that defines a rear surface is provided. The rear surface of the external wrapper is deep-drawn to form a machine compartment that defines a top wall, a bottom wall, and an interior wall. An inner liner is positioned within the external wrapper such that a gap is defined between the inner liner and the interior wall of the machine compartment. A vacuum is drawn within the gap.

A method and a system are disclosed for making an article of manufacture from a blank defining an internal opening. A stack of blanks are aligned and the internal openings of the blanks in the stack of blanks are machined by a rotary cutting tool to a finished dimension. The blanks are clamped together before machining in a numerically controlled machine tool. The blanks are subsequently formed individually in a sheet metal forming operation in which the inner perimeter of the internal openings is expanded as the blank is formed.

A plating steel sheet for hot press forming includes: a base steel sheet; an Al—Zn-based plating layer formed on at least one surface of the base steel sheet; and an Fe—Al-based surface alloy layer formed between the base steel sheet and the Al—Zn-based plating layer, wherein the Al—Zn-based plating layer can include 10-30 wt % of Zn, 1 wt % or less of Fe, and the balance of Al and impurities.

A method of manufacturing a guard element is configured to be used in a hair-cutting unit and which is of a design including a shaving track with hair-entry apertures where the shaving track has a thickness profile with at least one thickness value. According to the manufacturing method, a sheet is proviced, and the thickness profile of the shaving track according to the design of the guard element is realized in the sheet at a position where the shaving track is to be formed. Subsequently, material is removed from the sheet at the position where the shaving track is to be formed so as to create the hair-entry apertures.

A refrigerator cabinet is provided that includes an inner liner and an external wrapper. The inner liner is positioned within the external wrapper such that a gap is defined between the external wrapper and inner liner. The external wrapper includes a machine compartment including: a top wall, an interior wall, a bottom wall, a first side wall and a second side wall. A foot is defined by the external wrapper and is positioned below the machine compartment. The foot is at least partially defined by the bottom wall and at least partially supports the refrigerator cabinet.

Provided is a sheet material press forming method of press forming a formed part including a top portion with a protrusion having a blockage protrusive shape, the method including: preforming a high-strength steel sheet; and then forming it into a target shape without fractures or wrinkles, which is achieved by determining a shape in the preforming by press forming analysis according to the following steps: S1: the region of the protrusion having the target shape is discretized into two-dimensional elements and nodes for finite element analysis; and S2: the discretized portion are applied with internal stress in the normal directions of the two-dimensional elements from the inside of the discretized portion and deformed under the following conditions: (a) the two-dimensional elements are deformed within an elastic deformation range; and (b) adjacent ones of the two-dimensional elements have an angle therebetween which is free to change.
