摘要： The application discloses a punch and a die for stretching battery case body and its stretching process. The die for stretching the battery case body of the invention is specially designed with a stepped punch as a male die, at least one thinning ring as a female die, and a variable-wall-thickness stretching step. The variable-wall-thickness stretching step belongs to the thinning stretching. When the sheet or plate is stretched to the cup-shaped stretching piece by means of at least one-time forming stretching, and then through the thinning stretching, especially the variable-wall-thickness stretching with the stepped punch and at least one thinning ring to finally obtain the variable-wall-thickness battery case body with thin wall in the middle and thick wall at one end or both ends in the axial direction. The variable-wall-thickness battery case body can reduce the material consumption of the middle section of the case body on the one hand and ensure the roll-sealing strength of one end or both ends of the case body on the other hand, thus solving the contradictory problem between the amount of materials and the reliability of the roll sealing caused by the wall thickness of the battery case body.

摘要： The present invention belongs to the field of amorphous alloy thermoplastic forming, and discloses a plastic forming and gradient toughening method and a device based on ultrasonic vibration. The method includes: (a) dividing one or more portions to be toughened on an amorphous alloy part to be formed, the portion being used for generating a nanocrystalline toughening phase; (b) designing a toughening device for forming, wherein the toughening device comprises one or more inserts connected to an ultrasonic vibration amplitude transformer and one or more heating rods, the insert is disposed corresponding to the portion to be toughened and used for applying ultrasonic vibration to the portion to be toughened, and the heating rod is used for heating raw material blank to be processed to a forming temperature, and (c) placing the raw material blank in the device, heating it by the heating rod, and performing mold closing of the device to form a required amorphous alloy part, ultrasonic vibration being started in the mold closing process and stopped when mold opening is performed. Meanwhile, the invention further discloses the utilized device. With the method of the present invention, toughening and thermoplastic forming can be performed at the same time, so that integration of forming and toughening is achieved, which simplifies production processes, shortens the processing time and improves the dimensional accuracy.

摘要： A hydraulic tool working head (28) includes a frame (46), a ram (48) and a connection between the ram and the frame (Figure 6). The frame has a first section (63) with a hydraulic cylinder area, an opposite second section (66) and a middle section (64) connecting the first and second sections to each other. The ram is movably located in the hydraulic cylinder area and extends out of the first section of the frame towards the opposite second section of the frame. The connection between the ram and the middle section includes the middle section of the frame have two slots (70) extending into the opposite sides of the middle section and the ram having two cantilevered hook sections (76) which generally face towards each other (Figure 7). The hook sections have ends slidably ends (78) respectively located in the two slots of the middle section (Figure 8).
