This process can eliminate defects in the metal smelting process (such as casting porosity) and optimize the microstructure, thereby significantly improving the mechanical properties and compressive strength of the material. Compared with traditional cast pipe fittings, they are more reliable. However, large forged pipes are prone to sticking to the die during the forging and demolding process.

The demolding device of this invention facilitates demolding of the forging tube without damaging it, and also improves production efficiency.

[0004] Based on the search of the aforementioned patents and in conjunction with existing forging tube demolding devices, it was found that although the forging tube demolding device can demold the forging tube by rotating the left and right retaining rings, the left and right retaining rings need to be rotated manually, which reduces its rotation efficiency and is time-consuming and labor-intensive, thus reducing its practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This utility model provides a technical solution: a forging tube demolding device, including a base 1, a left retaining ring 11, and a right retaining ring 12. The top of the base 1 has an opening 13, and a demolding component is provided on the top of the base 1. A connecting component is provided between the left retaining ring 11 and the right retaining ring 12. The demolding component includes a bracket 21 fixedly connected to both sides of the top of the base 1, a drive shaft 22 connected to the bracket 21, a connecting frame 23 fixedly connected to the outside of the drive shaft 22, a worm gear 24 fixedly connected to the outside of the drive shaft 22, a worm 25 connected to the worm gear 24, and a worm 25 fixed to one end of the worm 25. A motor 26 is fixedly connected to the worm gear 25, which meshes with the worm wheel 24. A drive shaft 22 is rotatably connected to a bracket 21. Two connecting frames 23 are fixedly connected to the left retaining ring 11 and the right retaining ring 12, respectively. When the motor 26 starts, it drives the worm gear 25 to rotate. The rotation of the worm gear 25 drives the worm wheel 24 to rotate, which in turn controls the drive shaft 22 to drive the connecting frames 23 to rotate, thereby controlling the rotation of the left retaining ring 11 and the right retaining ring 12. When the left and right retaining rings 11 and 12 are joined together, they can act as a stopper during the demolding process of the forged tube. When the left and right retaining rings 11 and 12 are separated, they can... To facilitate the removal and demolding of the forged tube, the bracket 21 has rotating grooves 41 on both sides, and rotating blocks 42 are provided on both sides of the rotating grooves 41. The rotating blocks 42 are slidably connected to the rotating grooves 41 and are fixedly connected to the connecting frame 23. The rotation of the connecting frame 23 can drive the rotating blocks 42 to rotate, thereby improving the rotational stability of the connecting frame 23 and preventing the connecting frame 23 from tilting. The left retaining ring 11 and the right retaining ring 12 are respectively fixedly connected to the sides of the first reinforcing ribs 71, which are also fixedly connected to the connecting frame 23. 1. This can further improve the driving connection strength between the connecting frame 23 and the left retaining ring 11 or the right retaining ring 12, and improve the connection stability between the connecting frame 23 and the left retaining ring 11 and the right retaining ring 12. The bottom sides of the left retaining ring 11 and the right retaining ring 12 are respectively fixedly connected with the second reinforcing rib 81. The second reinforcing rib 81 is fixedly connected to the connecting frame 23. The second reinforcing rib 81 can further improve the driving connection strength between the connecting frame 23 and the left retaining ring 11 or the right retaining ring 12, and further improve the connection stability between the connecting frame 23 and the left retaining ring 11 and the right retaining ring 12.

[0027] Please see Figure 1 , Figure 5 , Figure 6 as well as Figure 7The connecting components include a first fixing plate 31 fixedly connected to both sides of the left retaining ring 11, a second fixing plate 32 fixedly connected to both sides of the right retaining ring 12, a first recess 33 on one side of the first fixing plate 31, a second recess 34 on one side of the second fixing plate 32, a drive plate 35 on both sides of the first recess 33, a bidirectional screw 36 connected to the drive plate 35, a connecting rod 37 fixedly connected to the drive plate 35, and connecting holes 38 on both sides of the second recess 34. The connecting rod 37 is inserted into the connecting hole 38, the bidirectional screw 36 is screwed to the drive plate 35, and the bidirectional screw 36 is rotatably connected to the first fixing plate 31. The drive plate 35 and the connecting rod 37 can be inserted into the second recess 34. By rotating the bidirectional screw 36, the two drive plates 35 can rotate in opposite directions. The two connecting rods 37 can be moved so that they can be inserted into the connecting holes 38, thereby further connecting and fixing the left retaining ring 11 and the right retaining ring 12, and further preventing the left retaining ring 11 and the right retaining ring 12 from rotating and separating. Two sliding grooves 51 are opened on one side of the first recess 33. A slider 52 is slidably connected in the sliding grooves 51. The slider 52 is fixedly connected to the drive plate 35. The movement of the drive plate 35 can make the slider 52 move synchronously. The slider 52 can prevent the drive plate 35 from rotating and can ensure that the drive plate 35 can only move vertically. A horizontal plate 61 is fixedly connected to the top of the bidirectional screw 36. A drive handle 62 is fixedly connected to one side of the top of the horizontal plate 61. The rotation of the drive handle 62 can control the horizontal plate 61 to rotate, which can facilitate the rotation of the bidirectional screw 36 and facilitate the control of the movement of the connecting rod 37.

[0028] Working principle: During operation, motor 26 drives worm 25 to rotate, which in turn drives worm wheel 24 to rotate, which in turn drives drive shaft 22 to rotate, which in turn drives connecting frame 23 to rotate, thereby moving left retaining ring 11 and right retaining ring 12. The self-locking characteristic of worm 25 and worm wheel 24 prevents left and right retaining rings 11 and 12 from rotating arbitrarily. When left and right retaining rings 11 and 12 are closed, drive plate 35 enters the second recess 34, and then drive handle 62 can be rotated. Rotation of drive handle 62 drives bidirectional screw 36 to rotate, which causes the two drive plates 35 to move to both sides. The movement of the drive plate 35 can drive the connecting rod 37 to move, and the connecting rod 37 can be inserted into the connecting hole 38, thereby connecting and fixing the left retaining ring 11 and the right retaining ring 12 to prevent them from separating. When demolding is required, the drive handle 62 is rotated in the opposite direction, causing the bidirectional screw 36 to rotate in the opposite direction, thereby causing the connecting rod 37 to disengage from the connecting hole 38. At this time, the motor 26 reverses, thereby driving the worm gear 25 to reverse, thereby causing the left retaining ring 11 and the right retaining ring 12 to rotate and separate, making it easy to remove the forged tube. The above is the working process of the entire device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
