Technical Field

[0001] The utility model relates to the field of component processing and forming, and more specifically, to a U-shaped round steel forming device. Background Technique

[0002] The round steel U-shaped pressing die is a die device for making U-shaped round steel. At present, there are many U-shaped round steel forming dies on the market. However, for general U-shaped round steel forming dies, during the use process, usually multiple processes are required to complete, and the die is damaged, resulting in too high a cost for replacing the die. Content of the Utility Model

[0003] 1. Technical Problems to be Solved

[0004] The purpose of the utility model is to provide a U-shaped round steel forming device to solve the related problems raised in the above background technique.

[0005] 2. Technical Solution

[0006] A U-shaped round steel forming device includes a stamping table for stamping U-shaped round steel raw materials, and further includes a stamping mechanism. Two fixing plates are fixedly connected to the upper end of the stamping table. An opening is provided at the center position between the two fixing plates. A stamping plate is movably arranged in the opening. The bottom of the stamping mechanism is fixedly connected to a stamping head that is butted against the upper end of the stamping plate. Two movable seats are movably arranged between the two fixing plates. The two movable seats are symmetrically arranged on both sides of the stamping plate, and the movable seats are rotatably connected between the fixing plates through a rotating shaft.

[0007] Preferably, a mounting plate is fixedly connected between the outer sides of the fixing plates. Springs are connected between the mounting plate and the outer side of the movable seat, and between the stamping plate and the bottom of the opening.

[0008] Preferably, the spring between the mounting plate and the outer side of the movable seat is a contraction spring, while the spring between the stamping plate and the bottom of the opening is an extension spring.

[0009] Preferably, a stop rod is also fixedly connected between the two fixing plates. The stop rod abuts against and limits the outer side of the movable seat.

[0010] Preferably, an installation groove is provided on one side of the movable seat close to the stamping plate, and a rotating disc is rotatably connected inside the installation groove.

[0011] Preferably, arc-shaped grooves for placing U-shaped round steel raw materials are provided on the movable seat, the rotating disc, and the upper end of the stamping plate.

[0012] 3. Beneficial Effects

[0013] Compared with the prior art, the advantages of the utility model are as follows:

[0014] The mold designed by the present utility model uses a stamping plate in cooperation with movable seats on both sides to form a placement mold for U-shaped round steel raw materials. During the stamping process, the existing stamping mechanism is directly used to press down the stamping head, so that the stamping plate can descend and the movable seats on both sides can rotate. With the above ingenious structural design, the forming of U-shaped round steel can be quickly completed. The structure is reasonably arranged, and the operation is very simple. Moreover, since the mold for placing U-shaped round steel raw materials adopts a combined design, the subsequent replacement cost is also reduced, improving the overall practical effect.

[0020] In the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, terms such as "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] Please refer to Figures 1-3 , a U-shaped round steel forming device, which includes a stamping table 1 for stamping the U-shaped round steel raw material 2, and further includes a stamping mechanism 6. Two groups of fixing plates 3 are fixedly connected to the upper end of the stamping table 1. An opening 4 is provided at the central position between the two groups of fixing plates 3. A stamping plate 5 is movably arranged in the opening 4. The bottom of the stamping mechanism 6 is fixedly connected with a stamping head 7 that is butted against the upper end of the stamping plate 5. Two groups of movable seats 8 are movably arranged between the two groups of fixing plates 3. The two groups of movable seats 8 are symmetrically arranged on both sides of the stamping plate 5, and the movable seats 8 are rotatably connected between the fixing plates 3 through a rotating shaft 9.

[0023] Among them, an installation plate 301 is fixedly connected between the outer sides of the fixing plates 3. Springs 302 are connected between the installation plate 301 and the outer side surfaces of the movable seats 8 and between the stamping plate 5 and the bottom of the opening 4. The spring 302 between the installation plate 301 and the outer side surface of the movable seat 8 is a contraction spring, while the spring 302 between the stamping plate 5 and the bottom of the opening 4 is an extension spring. A stop rod 303 is also fixedly connected between the two groups of fixing plates 3. The stop rod 303 abuts against and limits the outer side surface of the movable seat 8. An installation groove 801 is provided on the side of the movable seat 8 close to the stamping plate 5, and a rotating disk 802 is rotatably connected inside the installation groove 801. Arc-shaped grooves 803 for placing the U-shaped round steel raw material 2 are provided on the movable seats 8, the rotating disks 802, and the upper ends of the stamping plates 5.

[0024] Based on the above structure, when the utility model is in use, the staff places the round steel raw material 2 in the arc-shaped grooves 803 at the upper ends of the movable seat 8, the rotating disk 802 and the stamping plate 5 in a U-shape. Subsequently, the existing stamping mechanism 6 is started to drive the stamping head 7 to descend for stamping operations. The stamping table 7 first contacts the stamping plate 5 and applies pressure downward. The stamping plate 5 moves downward and compresses the springs 302 at the bottom. Moreover, the left and right mounting seats 8 rotate through the rotating shafts 9 under the action of pressure. The arc-shaped grooves 803 on the outer sides of the two sides of the round steel raw material 2 in the U-shape are located in the arc-shaped grooves 803 outside the rotating disk 802. As the stamping plate 5 descends, the U-shaped round steel is formed. When the profiling is completed, the stamping mechanism 6 moves upward. The left and right movable seats 8 return to their pre-loaded states due to the contraction force of the outer springs 302. The stamping plate 5 also returns to its pre-loaded state due to the elastic force of the springs 302, which facilitates subsequent production. At the same time, the stop lever 303 limits the angle of the movable seat 8.
