Embodiment 1
[0039] Example 1: as figure 1 As shown, a hydraulic cylinder block forging machine includes a main frame, the upper part of the main frame is provided with a pressurizing device, the interior of the main frame is provided with a forging device that slides along the main frame and is connected with the pressurizing device, and the lower part of the main frame is provided with an inner The core lifting device is provided with an inner core backstop device on the worktable at the lower part of the main frame.
[0040]The main frame includes a main oil cylinder mounting plate 29 and a worktable 9 arranged in parallel. The main oil cylinder mounting plate 29 and the worktable 9 are connected by four parallel round steel support columns 12, and the worktable 9 is connected with the inner core lifting device. ; The worktable 9 is provided with a circular worktable 13, and the circular worktable 13 and the worktable 9 are provided with through holes 30 corresponding to the inner core ...
Embodiment 2
[0050] Example 2: The structure differs from Example 1 in that the inner mold 4 is equally divided into six pieces by a circular mold to form a six-open inner mold. like figure 1 As shown, other structures are the same, and are not repeated here.
[0051] The working process of the forging machine is as follows: figure 1 As shown in the figure, after starting up, the hydraulic press is in the original state, and the operator puts the heated seamless pipe 5 on the round table 13; the operator steps on the foot switch, the lower cylinder 8 works, and the lower cylinder is pulled through the lower cylinder piston 19 The piston connecting plate 20 moves upward, the lower oil cylinder piston connecting plate 20 is fixed with the lower oil cylinder tie rod 22, the lower oil cylinder tie rod 22 pushes the inner core fixing plate 17, the inner core fixing plate 17 is connected with the gear shaft 16 by bolts, and the gear shaft 16 pushes The inner core 7 penetrates into the seamless...
Embodiment 3
[0052] Embodiment 3: The difference from Embodiment 1 is that the forging die device is an integral concave die 24 without an inner die, such as figure 2 As shown, other structures are the same, and are not repeated here.
[0053] The working process of the forging machine is as follows: the schematic diagram of the forging hydraulic press is as follows figure 1 As shown, the structural schematic diagram of the overall die 24 is as follows figure 2 shown. After starting up, the hydraulic press is in the original state, and the operator puts the heated seamless pipe 5 on the round table 13; 20 moves upward, the lower oil cylinder piston connecting plate 20 is fixed with the lower oil cylinder pull rod 22, the lower oil cylinder pull rod 22 pushes the inner core fixing plate 17, the inner core fixing plate 17 is connected with the gear shaft 16 by bolts, and the gear shaft 16 pushes the inner core 7 Penetrate into the seamless tube 5, the gear shaft 16 continues to work, pu...
