Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 6 The present invention provides a technical solution: a large round bar press forging device, comprising an operating table 7, one side of the operating table 7 is vertically connected to a bracket 4, the upper end of the bracket 4 extends to the top of the operating table 7 and is connected to a connecting seat 2, the bottom of the connecting seat 2 and the top of the operating table 7 are connected to a mold support 6, and the mold support 6 located on the upper layer is telescopically connected to the connecting seat 2, such as Figure 1 As shown, a hydraulic rod 5 is connected between the mold support 6 located on the upper layer and the connecting seat 2, and a first guide rod 1 is connected to the top of the mold support 6 located on the upper layer. The upper end of the first guide rod 1 passes through the connecting seat 2, and is connected to a sleeve 3 on the connecting seat 2. The first guide rod 1 is slidably connected in the sleeve 3, and the hydraulic rod 5 pushes the mold support 6 to move downward. During the movement, the first guide rod 1 slides in the sleeve 3. Under the guiding action of the sleeve 3, the stable sliding of the mold support 6 is effectively guaranteed, thereby improving the processing quality.

[0025] like Figure 4 , 5 As shown, a symmetrically arranged first mold base 16 is slidably connected to one side close to the mold support 6, a second cross plate 15 is connected to the end of the first mold base 16, two ends of the second cross plate 15 are connected to the first end plate 9, a first electric telescopic rod 11 is connected to one side of the first end plate 9, the first electric telescopic rod 11 is fastened to the outer wall of the mold support 6, and a symmetrically arranged second mold base 24 is slidably connected to one side close to the first mold base 16, an end of the second mold base 24 is connected to the first cross plate 14, a second end plate 10 is connected to one side of the first cross plate 14, a second electric telescopic rod 13 is connected to one side of the second end plate 10, and the second electric telescopic rod 13 is fastened to the outer wall of the mold support 6. When used for processing, the first electric telescopic rod 11 and the second electric telescopic rod 13 respectively pull the first mold base 16 and the second mold base 24 to move toward each other, so that their ends abut against and are located on the top of the mold support 6, and the staff can select and use the first mold base 16, the second mold base 24 and the mold support 6 according to the needs of processing.

[0026] At the same time, in order to improve the overall stability of the first electric telescopic rod 11 and the second electric telescopic rod 13, a mounting seat 12 is fixedly connected to the outer wall of the mold support 6, one end of the first electric telescopic rod 11 and the second electric telescopic rod 13 are connected to the mounting seat 12, and a plurality of grooves 25 are provided on the mold support 6, the first mold seat 16, and the second mold seat 24. The diameter of the grooves 25 increases from the inside to the outside. When the mold support 6, the first mold seat 16, and the second mold seat 24 are placed in a staggered manner, the grooves 25 are placed in sequence, which not only ensures that the staff can make a choice according to the processing needs, but also enables the normal processing.

[0027] like Figure 4 , 5 As shown in Figures 6, in order to facilitate the staff to install and disassemble the first mold base 16 and the second mold base 24, connecting screws 27 are fastened at the ends of the first electric telescopic rod 11 and the second electric telescopic rod 13, and through holes 26 are opened on the first end plate 9 and the second end plate 10.
