摘要： The invention refers to a device and a tool for cold expansion of fastener holes. The advantages of the device and tool are in the possibility to control the degree of cold expansion. The device (61) comprises a hydraulic cylinder (27) in which a piston (26) with a piston rod (25) is placed, to whose end a mandrel (1) of a tool (60) is fixed. To flange (9) a threaded bush (7) of the tool (60) is immovably fixed, such that in an axial blind hole (55) of the piston rod (25), a linear displacement sensor (34), is positioned, immovably fixed to the hydraulic cylinder (27). A magnet (33) is designed for activating the linear displacement sensor (34), which is connected to the control block (38).

摘要： The invention refers to a tool for cold expansion of fastener holes. The tool comprises a mandrel (1) with a conical working part (2), a cylindrical sleeve (4) with a conical hole (5), wherein the sleeve (4) is entirely split from end to end into separate, laterally touching one another, segments (6), fixed in a cylindrical hole (14) of a threaded bush (7) and along the outer cylindrical surface (8) of the mandrel (1). The bush (7) is attached immovably to a device, fixing the segments (6), and each segment (6) gets into contact with the conical surface (2) of the mandrel (1) along only one generatrix (16), laying in the symmetry plane (17) of the respective segment (6). The advantage of the tool is in the possibility to control the degree of cold expansion.

摘要： The invention refers to a device for cold expansion of fastener holes. The device comprises a hydraulic cylinder (27) in which a piston (26) with a piston rod (25) is placed, to whose end a mandrel (1) of a tool (60) is fixed. In a flange (9) a thread is made, through which an immovable fixation of the tool (60) is implemented, such that in an axial blind hole (55) of the piston rod (25), a linear displacement sensor (34), is positioned, immovably fixed to the hydraulic cylinder (26). A magnet (33) is designed for activating the linear displacement sensor (34), which is connected to the control block (38). The advantage of the device is in the possibility to control the degree of cold expansion.
