[0002] The mandrel is an important tool that is resistant to high temperature and high pressure and is placed on the core of the rolled steel pipe during rolling. The smoothness of the mandrel surface has a direct impact on the quality of the inner wall of the rolled steel pipe. In order to maintain the smoothness of the mandrel surface, the mandrel needs to be stored stably. A storage rack is needed to store the mandrel. When storing the mandrel, the mandrel is supported on a platform or pipe during storage.

[0021] In order to make the technical means, technical features, purpose of the utility model and technical effects achieved by the utility model easier to understand, the utility model is further explained below with reference to specific illustrations.

[0022] like Figures 1-4 As shown, a tube rolling mill core rod storage rack includes a placement rack 1. The placement rack 1 is made of profile welding, has high structural strength, can be stably supported on the ground, and ensures that the core rods are stored firmly. Multiple layers of storage units are installed on the placement rack 1 from top to bottom. The number of storage units on each layer is two, and the two storage units on each layer are symmetrically distributed on both sides of the placement rack 1. The storage unit includes a fixed support assembly and a movable support assembly. The fixed support assembly is installed at one end of the placement rack 1, and its installation position is fixed relative to the placement rack 1. The movable support assembly is installed at the other end of the placement rack 1. The movable support assembly includes a transverse mechanism and a movable support mechanism. The transverse mechanism is connected to the placement rack 1, and the movable support mechanism is connected to the transverse mechanism. The movable support mechanism is driven by the transverse mechanism to move closer to or away from the fixed support assembly, thereby adjusting the relative distance.

[0023] like Figure 1-Figure 3As shown, the fixed support assembly includes a first connecting channel steel 2, a first base plate 3, a first driving mechanism and a first supporting mechanism. The first connecting channel steel 2 is fixedly connected to the placement frame 1 by welding. The first connecting channel steel 2 is vertically distributed to the placement frame 1. The first base plate 3 is installed on the top of the first connecting channel steel 2. Two first T-slots 4 are processed on the first base plate 3. The two first T-slots 4 are distributed in parallel. The first supporting mechanism is installed in the first T-slot 4. The first driving mechanism is installed at the bottom of the first connecting channel steel 2. The first driving mechanism is transmission-connected to the first supporting mechanism, and the first driving mechanism drives the first supporting mechanism to slide along the first T-slot 4.

[0024] The first driving mechanism includes a driving motor 5, a forward and reverse thread screw 6 and two connecting blocks 7. The driving motor 5 and the forward and reverse thread screw 6 are both installed on the first connecting channel steel 2. The driving motor 5 is transmission-connected to the forward and reverse thread screw 6. The driving motor 5 drives the forward and reverse thread screw 6 to rotate relative to the first connecting channel steel 2. The two connecting blocks 7 are threadedly connected to the two ends of the forward and reverse thread screw 6. The two connecting blocks 7 are symmetrically distributed, and the driving motor 5 can realize forward and reverse rotation.

[0025] The first supporting mechanism includes two movable base plates 8, which are connected to the two connecting blocks 7 in a one-to-one correspondence. Two first T-shaped sliders 9 are processed on the lower surface of the movable base plate 8. The two first T-shaped sliders 9 are respectively slidably connected in the two first T-shaped grooves 4. A wheel bracket 10 is installed on the upper surface of the movable base plate 8. A support wheel 11 is installed on the wheel bracket 10. The support positioning of the mandrel is achieved by the two support wheels 11. The support wheel 11 is pivotally connected to the wheel bracket 10 and can rotate relative to the wheel bracket 10. The outer surface of the circumference of the support wheel 11 is covered with a rubber ring 2 3. The driving motor 5 drives the forward and reverse threaded screws 6 to rotate, and drives the two movable base plates 8 to move relatively closer or farther away through the connecting block 7 threadedly connected to the forward and reverse threaded screws 6, thereby adjusting the spacing between the two support wheels 11 to meet the requirements of stable support for core rods of different diameters. During the movement, the movable base plate 8 is guided and limited by the cooperation of the first T-shaped slider 9 and the first T-shaped slot 4. During support, the rubber ring 23 can increase the friction between the core rod and the support wheel 11, maintain the stability of the support for the core rod, and avoid hard contact between the core rod and the support wheel 11, thereby preventing damage to the surface of the core rod.

[0026] like Figure 1 、 Figure 2 and Figure 4As shown, the transverse mechanism includes a transverse base plate 12, a transverse screw 13, a transverse motor 14 and a transverse movable plate 15. The transverse base plate 12 is fixedly mounted on the placement frame 1 and distributed along the length direction of the placement frame 1. Two parallel transverse T-slots 16 are processed on the transverse base plate 12. The transverse screw 13 and the transverse motor 14 are both installed on the transverse base plate 12. The transverse motor 14 is transmission-connected with the transverse screw 13 and the transverse screw 13 is driven by the transverse motor 14 to rotate. A transverse T-block 17 is processed on the transverse movable plate 15. The transverse T-block 17 is slidingly connected in the transverse T-slot 16. The transverse movable plate 15 is transmission-connected with the transverse screw 13. The rotation of the transverse screw 13 drives the transverse movable plate 15 to move relative to the transverse base plate 12, and the sliding cooperation between the transverse T-slot 16 and the transverse T-block 17 guides and limits the movement of the transverse movable plate 15.

[0027] The mobile support mechanism includes a second connecting channel steel 18, a second base plate 19, a second driving mechanism and a second supporting mechanism. The second connecting channel steel 18 is vertically and fixedly connected to the transverse movable plate 15. The second base plate 19 is installed on the top of the second connecting channel steel 18. Two parallel second T-slots 20 are processed on the second base plate 19. The second supporting mechanism is slidably connected in the second T-slot 20. The second driving mechanism is installed at the bottom of the second connecting channel steel 18. The second driving mechanism is transmission-connected to the second supporting mechanism. The second driving mechanism has the same structure and working principle as the first driving mechanism. The second supporting mechanism has the same structure and working principle as the first supporting mechanism. The structures of the second driving mechanism and the second supporting mechanism will not be described in detail here.

[0028] like Figure 1-Figure 3 As shown, a baffle 21 is fixedly connected to the side of the first connecting channel steel 2 facing away from the movable support mechanism, and a protective pad 22 is adhered to the side of the baffle 21 facing the first bottom plate 3. The protective pad 22 is made of flexible material. The baffle 21 limits the storage position of the core rod to ensure that the end position of the core rod is uniform when stored, and the storage is neat and orderly. The protective pad 22 protects the end of the core rod to avoid damage to the end of the core rod due to hard contact between the core rod and the baffle 21.

[0029] The working principle of this utility model is:

[0030] When in use, according to the specifications (diameter and length) of the mandrel to be stored, first adjust the first support mechanism, specifically, start the driving motor 5 to drive the positive and negative threaded screws 6 to rotate, and through the threaded connection between the positive and negative threaded screws 6 and the connecting block 7, drive the two movable base plates 8 to move relatively close or away, and adjust the spacing between the two support wheels 11 to meet the support in the diameter direction of the mandrel, so that the center of gravity of the mandrel after support is lowered to ensure the stability of the support. Secondly, adjust the transverse mechanism, start the transverse motor 14 to drive the transverse screw 13 to rotate, and drive the transverse movable plate 15 to move relative to the transverse base plate 12, and then adjust the distance between the mobile support mechanism and the fixed support assembly to meet the support in the length direction of the mandrel. Similarly, according to the adjustment method of the first support mechanism, the second support mechanism is adjusted accordingly, so that the second support mechanism and the first support mechanism can meet the support requirements of the mandrel with the same diameter specification, and the mandrel to be stored is placed between the two support wheels 11, and its end is close to the baffle 21, so that the mandrel storage is stable, reliable and orderly.

[0031] The storage units on both sides of the rack 1 and on the upper and lower sides are relatively independent and can be adjusted individually for core rods of different specifications to meet the storage requirements of core rods of different specifications. The rack has a large storage space, can store a large number of core rods, and has a wide range of applications.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. In other words, any equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the technical scope of the present invention.
