Below in conjunction with accompanying drawing, the utility model is described in further detail by the specific embodiment:

The specific embodiment:

Referring to Fig. 1, Fig. 2, present embodiment adopts vertical four beams, four rod structures, four posts be four jiaos of upright column 7, four beams be not from top to bottom as frame entablature 1, as the stretching beam 2 of stretching slide block, as the flanging beam 3 of blankholder slide with as the sill 4 of frame.Wherein, stretching beam 2 adopts suspended structure up and down with flanging beam 3, and concrete enforcement is that flanging beam 3 is suspended on the stretching beam 2 times, and stretching cylinder 5 is installed in the entablature 1, and flanging cylinder 6 is installed in the stretching beam 2.

Fig. 6, shown in Figure 8, the flanging cylinder 6 in the present embodiment has four, and stretching cylinder 5 is three, and on horizontal layout, four flanging cylinders 6 are four jiaos of distributions, and four root posts 7 are positioned at its periphery, and three stretching cylinders 5 are arranged on the straight line.

Fig. 7, shown in Figure 9 is provided with routinely, and flanging working face 8 is positioned at periphery, and stretching working face 9 is positioned at central authorities.

As shown in Figure 1 and Figure 2, the present embodiment hydraulic press is equipped with travelling table 10, corresponding to the inflow location of travelling table 10, top inner cylinder 11 is set, simultaneously, be provided with corresponding to the outflow location of travelling table 10 and take blame for others 12 outward, top inner cylinder 11 and to take blame for others outward 12 be the interlocking setting.

In order to improve the equipment safety in utilization, in the present embodiment, two cover safety devices are set, comprise the hydraulic control safe locking device and manually control safety cock.

Referring to Fig. 3, the hydraulic control safe locking device is the stretching beam hangers 13 that is fixedly connected on stretching beam 2, entablature hanger 14 is set on the entablature 1 of correspondence position, on stretching beam hangers 13, horizontal pin-and-hole is set, the latch 15 that can be inserted in the horizontal pin-and-hole is installed on the entablature hanger 14, and latch 15 is to be power source with hydraulic pressure propulsion cylinder 16;
