[0002] In the piping system, stainless steel elbows are pipe fittings that change the direction of the pipeline. After the stainless steel elbows are formed by the elbow forming machine, they still have defects such as uneven wall thickness and non-round diameter, so they need to be reshaped by the shaping machine.

[0003] Since stainless steel elbows come in a variety of sizes, corresponding shaping molds also require a variety of specifications. Before shaping stainless steel elbows of different sizes, the shaping mold must be replaced. However, the shaping mold is often very heavy, making it difficult to load the mold onto the shaping machine's workbench. First, the mold must be lifted with a forklift's forks, then the forks adjusted to a position above the workbench surface before the mold is placed on the workbench. However, this mold replacement method is inefficient and hinders shaping progress. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] The utility model provides a mold moving device for a stainless steel elbow shaping machine, comprising a chuck I11, a chuck II12, a support column 2 and a bearing plate 3. The chuck I11 and the chuck II12 are both semicircular rings. The support column 2 comprises a vertical section and an oblique section. One end of the oblique section is fixed to the chuck II12, and the other end is fixed to the top of the vertical section. The oblique section gradually slopes downward from one end connected to the chuck I11 to one end connected to the vertical section.

[0024] The supporting plate 3 is mainly used to support the mold when the mold is replaced. The support column 2 serves to connect the chuck Ⅰ11 and the supporting plate 3, and the oblique rod can bear the vertical weight and horizontal force of the mold on the supporting plate 3 to maintain the balance of the entire mold shifter.

[0025] The chuck I11 and the chuck II12 can be detachably matched and fixed together to form a sleeve 1, so that the sleeve 1 is clamped on the connecting column of the shaping machine, and the supporting plate 3 is located in front of the feed port of the working platform of the shaping machine; the chuck I11 and the chuck II12 can be fixed at a distance from each other, so that the sleeve 1 and the connecting column are matched with each other, and the sleeve 1 can be rotated on the connecting column, thereby rotating the supporting plate 3 to the side of the feed port.

[0026] The basic method of use of the present invention is as follows: first, clamp Ⅰ11 and clamp Ⅱ12 are respectively placed on the connecting column of the shaping machine (ensuring that the carrier plate 3 is located in front of the feed port of the work platform), then clamp Ⅰ11 and clamp Ⅱ12 together so that the sleeve 1 is tightly clamped on the connecting column, thereby fixing the entire mold shifter on the connecting column. When a new mold needs to be replaced, the new mold is hoisted on the lifting device of the crane, the lifting device moves, and the mold is transferred to the top of the carrier plate 3. The lifting device descends and the mold is placed on the carrier plate 3. Then, the cylinder pushes the mold on the carrier plate 3 and pushes the mold onto the work platform. Then, the flat surfaces of clamp Ⅰ11 and clamp Ⅱ12 are separated from each other by a gap and fixed. This increases the inner diameter of the sleeve 1 and forms a clearance fit with the connecting column, making it easier to rotate the mold shifter 90 degrees and rotate the carrier plate 3 from one side of the work platform feed to the adjacent side, preventing the mold shifter from interfering with the feed of the shaping machine. When a new mold needs to be replaced next time, the sleeve 1 is rotated 90 degrees, and then the flat surface of the chuck I11 and the flat surface of the chuck II12 are contacted and fixed, so that the sleeve 1 is re-clamped on the connecting column and the supporting plate 3 is located in front of the feed port.

[0027] The specific method for fixing chuck I11 and chuck II12 is as follows: chuck I11 is provided with a threaded through-hole 111 extending from the curved surface to the flat surface, and chuck II12 is provided with a threaded blind hole 121 on the flat surface opposite to threaded through-hole 111. Threaded through-hole 111 and threaded blind hole 121 in corresponding positions can be penetrated by a common bolt, which is simultaneously threadedly connected to threaded through-hole 111 and threaded blind hole 121. Due to the length of the bolt, chuck I11 and chuck II12 can be threadedly connected to the ends of the bolt respectively. In this case, there is a gap between the flat surfaces of chuck I11 and chuck II12. The inner diameter of sleeve 1 is larger than the diameter of the connecting post, allowing sleeve 1 to rotate on the connecting post.

[0028] Specifically, the support column 2 includes a splint I21, a splint II22, a steel plate I23 and a steel plate II24. The splint I21 and the splint II22 are arranged at intervals and are both composed of a vertical portion and an oblique portion. One end of the oblique portion is fixed on the clamp II12, and the bottom end of the vertical portion is fixed to the bearing plate 3. The two side surfaces of the steel plate I23 are respectively fixed to the vertical portions of the splint I21 and the splint II22, and the two side surfaces of the steel plate II24 are respectively fixed to the oblique portions of the splint I21 and the splint II22.

[0029] The support plate 3 comprises a flat plate I 31, a flat plate II 32, a square tube 33, and multiple ribs 34. One end of the square tube 33 is fixed to the bottom end of the vertical section. Flat plates I 31 and II 32 are respectively fixed to the two opposite long side walls of the square tube 33. The width of flat plate II 32 is greater than that of flat plate I 31. Flat plate I 31, the top surface of the square tube 33, and flat plate II 32 together form the support surface on which the mold can be supported. To strengthen the connection between flat plate II 32 and square tube 33, multiple ribs 34 are used to strengthen the fixation between flat plate II 32 and square tube 33, and the ribs 34 are located below flat plate II 32.

[0030] In order to increase the friction of the bearing surface and prevent the mold from sliding from the side of the bearing surface when it is hoisted on the bearing surface by a crane, causing safety hazards, several through holes 4 are provided on the top surface of the plate I 31, the plate II 32 and the square tube 33.

[0031] The specific connection method between the support column 2 and the square tube 33 is as follows: the bottom of the vertical portion of each of the clamping plates I 21 and II 22 is provided with a square hole 5. The square tube 33 is inserted into the square holes 5 of the clamping plates I 21 and II 22 in sequence, and the square tube 33 is welded to the inner wall of the square hole 5. This connection method increases the connection area between the square tube 33 and the support column 2, and strengthens the connection.

[0032] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
