The invention relates to a cell differential steel shell and a process for producing the same. The cell differential steel shell is a hollow cylinder which has a closed anode head and an enlarged and open shell opening, with the wall thickness of the middle segment of the hollow cylinder being smaller than that of the anode head as well as of the shell opening. The process comprises the following: a step of blanking and light drawing by means of a multi-stage punch, which forms a bow-shaped blank; a step of redrawing, which reduces the diameter of the blank, increases the height of the blank and reduces the wall thickness of the middle segment of the hollow cylinder, keeping the wall thickness of the anode head; a step of deep drawing, which reduces the diameter, increases the height and reduces and keeps the outer diameter of the hollow cylinder and the wall thickness of the middle segment to the standard thickness required by the design; a step of deep drawing, which forms the shell opening and keeps the thickness of the shell opening equal to that of the blank; a step of shaping the anode head and punching two steps, which keeps the thickness of the anode as well as the two steps equal to that of the blank; a step of punching shear of the scrap of the shell opening, which forms the finished product of the differential steel shell. The invention is capable of increasing the capacity of the cell steel shell, thereby increasing the filling amount of an active substance, improving the discharge performance of the cell and prolonging the service life of the cell.

The invention discloses a special-shaped tube bundle heat exchanger with continuous spiral baffle double-shell side combination. The head at one end is provided with a tube pass inlet and a tube pass outlet, and one of the tube bundles and one of the tube bundles are also arranged between the tube sheets. Two; one of the tube bundles is composed of one of a plurality of heat transfer tubes, arranged between the central tube and the shell; the second tube bundle is composed of two of a plurality of heat transfer tubes, arranged in the central tube; one of the heat transfer tubes is a non- Special-shaped tubes with smooth walls, the second of the heat transfer tubes is a spiral flat tube; one of the fixed-distance tubes and the tube bundle passes through the spiral baffle, and its two ends are respectively connected with the tube sheet, and the spiral baffle is fixed by the fixed-distance tube; the tube bundle The two ends of the second are also respectively connected with the tube sheet; there are two notches corresponding to the shell-side inlet and the shell-side outlet of the heat exchanger respectively on the central tube. The heat exchanger of the present invention adopts two tube bundles with different heat transfer tube structures, less fluid back-mixing, no flow dead zone, little influence of bypass flow and leakage flow, and can make full use of the diameter of the shell to arrange heat transfer tubes. High thermal coefficient.

This invention relates to electron device shell with label, which comprises open shell, load board, connection board and label block, wherein, the load board is down the shell open to connect to shellthrough card hole connection board; the label block is set on load board with protruding parts on both sides; one protruding part is used to set connection board card; the other protruding part is set down shell board to set the label card into open hole.

The invention discloses a self-adaptive shell-opening track of a shell-opening machine. The self-adaptive shell-opening track comprises lower tracks and upper tracks, wherein lower concave tracks are arranged on the lower tracks, first concave arcs, second concave arcs and first ribs are arranged on each lower concave track, upper concave tracks are arranged on the upper tracks, third concave arcs, fourth concave arcs and second ribs are arranged on each upper concave track, and the third concave arcs, the fourth concave arcs and the second ribs are arranged along each upper concave track. The self-adaptive shell-opening track of the shell-opening machine has the advantages that the self-adaptive shell-opening track of the shell-opening machine can open shells of different thicknesses and shapes of cashew nuts with shells, the problem that different tracks are needed to be replaced for different sizes of cashew nuts with shells in actual production is solved, the efficiency of opening the shells of cashew nuts is high, and the self-adaptive shell-opening track is convenient and quick to use and suitable for large-scale shell-opening production of cashew nuts.

The inventive drum type washing machine comprises: a drum type washing barrel, a front panel around a feed opening; a washing machine shell, a front frame reinforced plate, a machine door, a hinge, a locking unit and an opening shell; wherein the machine door can be a machine door arranged at a first side of a plumb line through the center of the feed opening by the hinge in a first mode or a machine door arranged at a second side opposite to the first side of the plumb line by the hinge in a second mode; the plane shapes of the front frame reinforced plate, opening shell and machine door arerespectively constituted by different components in point symmetry with the center in the first and second mode; and the washing machine shell and front panel are both constituted by same components in a first and second mode.
