The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, portable tube bending machine of the present invention, comprise: fuselage 1, be arranged on bending die 6 on the fuselage by locating shaft 14, be provided with clamping die 5 by connecting plate 11 on the bending die 6, the clamping die 5 here, connecting plate 11 and bending die 6 are integrated---referring to shown in Figure 4, though in processing, increased difficulty,, can reduce workman's operation link, increase work efficiency; Be movably set with on the described fuselage 1 and hold out against screw mandrel 2, holding out against an end of screw mandrel 2 is threaded with the die holder 4 that holds out against on being slidingly arranged in fuselage 1, the other end that holds out against screw mandrel 2 is provided with regulating handle 9, hold out against and be movably set with withstanding tight model 7 on the die holder 4, and clamping die 5 and withstanding tight model 7 lay respectively at the both sides of bending die 6, hold out against die holder 4 and be provided with journal stirrup 12, be equipped with the puller bolt 13 that matches with withstanding tight model 7 by the screw thread activity in the journal stirrup 12 in a side away from bending die 6; In the present embodiment, described hold out against on the screw mandrel 2 to be provided with by screw thread hold out against slide block 3, hold out against slide block 3 and be provided with rotating shaft 31, as shown in Figure 3, the described both sides that hold out against slide block 3 offer sliding recess respectively, also be provided with a pair of pressing plate that matches with sliding recess 10 on the described fuselage 1,10 activities are embedded in the sliding recess of a corresponding side to pressing plate for this; Described die holder 4 movable sets that hold out against are in rotating shaft 31, and the bottom that holds out against die holder 4 is provided with and prevents to hold out against the positive stop lug boss 41 that die holder 4 rotates towards a side---referring to shown in Figure 5; Hold out against also to be provided with on the die holder 4 to pull and hold out against the operating grip 8 that die holder 4 rotates towards opposite side; The loading and unloading of bending die 6 for convenience, as shown in Figure 2, the top of described locating shaft 14 is provided with installation shaft 15, the outer surface of installation shaft 15 is surrounded by six spline planes, and, the outline line of installation shaft 15 cross sections is regular hexagon, and described bending die 6 is provided with and installation shaft 15 corresponding installing holes, and bending die 6 is sleeved on the installation shaft 15 by installing hole.
