DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a variable diameter pipe forging machine with an auxiliary positioning mechanism, comprising: a machine body 1 and a movable ring 10, a slide bar 2 is fixedly connected to the top of the machine body 1, a top plate 3 is fixedly connected to the top of the slide bar 2, a hydraulic cylinder 4 is installed on the top of the top plate 3, a sliding plate 5 is fixedly connected to the bottom of the hydraulic cylinder 4, and through holes are opened around the sliding plate 5 for the slide bar 2 to slide.

[0023] A reducer mold 6 is provided at the bottom of the sliding plate 5, and a connecting plate 7 is fixedly connected to the top of the body 1; a connecting ring 8 is slidably connected to the outer side of the slide rod 2, and a sliding groove for sliding the slide rod 2 is provided inside the connecting ring 8, and a first spring 9 is sleeved on the outer side of the slide rod 2, and the top of the first spring 9 is fixedly connected to the connecting ring 8; a movable ring 10 is fixedly connected to the bottom of the first spring 9, and a second spring 12 is fixedly connected to the bottom of the movable ring 10, and the bottom of the second spring 12 is fixedly connected to the top of the body 1, and the outer side of the movable ring 10 is movably connected to the first connecting rod 11 through a rotating shaft; a first limit block 13 is movably connected to one side of the first connecting rod 11 through a rotating shaft, and a slider 14 is fixedly connected to the bottom of the first limit block 13, and a sliding groove for sliding the slider 14 is provided inside the body 1, and a circular groove 15 and a debris removal groove 16 are provided on the upper end surface of the connecting plate 7, and the movable ring 10 forms a rotating structure with the first connecting rod 11 through a rotating shaft, and the movable ring 10 and the slide rod 2 form a sliding structure.

[0024] During specific implementation, when processing the reducer, a reducer forging machine is required. The reducer forging machine can forge the end of the reducer through a die. When assisting in positioning the pipeline, the pipeline is placed on the connecting plate 7, and then the hydraulic cylinder 4 is started to drive the sliding plate 5 to move downward. When the sliding plate 5 moves, the connecting ring 8 is squeezed. The connecting ring 8 can push the movable ring 10 to move downward through the first spring 9. When the movable ring 10 moves, it can squeeze the second spring 12. Since the elastic force of the second spring 12 is smaller than that of the first spring 9, the first spring 9 will shrink first. When the movable ring 10 moves, it will push the first connecting rod 11 to rotate and unfold. The first connecting rod 11 can push the first limit block 13 to move. Since the movable ring 10, the first connecting rod 11 and the first limit block 13 are provided with four groups, the four groups of first limit blocks 13 will move synchronously to push the pipeline to the center of the connecting plate 7.

[0025] When the sliding plate 5 continues to move downward, since the slider 14 can no longer move, the first spring 9 will contract. When the reducer die 6 contacts the end of the pipe, forging can be carried out. After the forging is completed, the sliding plate 5 will rise. At this time, the second spring 12 will reset and push the movable ring 10 upward, so that the first limit block 13 will be released from the clamping of the pipe. The waste chips generated during the forging of the pipe will fall into the sliding groove of the slider 14. The waste chips in the sliding groove can be pushed into the circular groove 15 and then discharged through the debris discharge groove 16. The above operation can facilitate the auxiliary positioning of the pipe on the reducer forging machine.

[0026] See also Figure 1 , Figure 2 and Figure 4An electric push rod 17 is installed inside the connecting plate 7, and the bottom of the electric push rod 17 is movably connected to a second connecting rod 18 around a rotating shaft, and one side of the second connecting rod 18 is movably connected to a connecting rod 19 through a rotating shaft; the outer side of the connecting rod 19 is movably connected to the sliding plate 5 through a rotating shaft, and one side of the connecting rod 19 is movably connected to a rotating rod 20 through a rotating shaft, and one side of the rotating rod 20 is movably connected to a second limit block 21 through a rotating shaft; the outer side of the second limit block 21 is slidably connected to a fixed block 22, the top of the fixed block 22 is fixedly connected to the sliding plate 5, and a movable groove for the second limit block 21 to slide is opened inside the fixed block 22, the second connecting rod 18 forms a rotating structure with the connecting rod 19 through the rotating shaft, and the second limit block 21 and the fixed block 22 form a sliding structure.

[0027] During specific implementation, when processing the reducer, a reducer forging machine is needed. The reducer forging machine can forge the end of the reducer through a mold. When installing the reducer mold 6, the reducer mold 6 is sent to the bottom of the sliding plate 5, and then the electric push rod 17 is started to push the four groups of second connecting rods 18 to rotate. When the second connecting rod 18 rotates, it will push the connecting rod 19 to rotate. When the connecting rod 19 rotates, the bottom will push the second limit block 21 to slide in the fixed block 22 through the rotating rod 20. When the four groups of rotating rods 20 enter the annular groove at the top of the reducer mold 6, the reducer mold 6 can be limited to complete the installation of the reducer mold 6. In this way, the above operation can facilitate the installation of the reducer mold 6 in the reducer forging machine.

[0028] To sum up: in the reducer forging machine using the auxiliary positioning mechanism, first put the pipe on the connecting plate 7, then start the hydraulic cylinder 4 to drive the sliding plate 5 and the reducer die 6 to move downward, and when the reducer die 6 contacts the end of the pipe, it can be forged to expand the diameter of the end of the reducer die 6. This is the characteristic of the reducer forging machine with the auxiliary positioning mechanism.
