Description

Technical Field

[0001] The utility model relates to the technical field of crucible shaping, in particular to an adjustable tooling for crucible shaping. Background Art

[0002] In recent years, with the changes in the carbon-carbon crucible market, the crucible preform has become thinner due to the requirement of cost control. After the crucible preform becomes thinner, the deformation of the crucible has become a major problem that is easy to occur. The deformation of the crucible preform during transportation, lifting and loading may cause the crucible to be unable to be processed and formed, thus causing the crucible to be scrapped. Therefore, before the crucible preform is formed and loaded into the furnace, the crucible needs to be solidified and shaped. The shaped crucible can maintain its shape during transportation, lifting and loading, thereby ensuring the crucible yield. The traditional shaping method usually uses a cylindrical tooling that matches the inner diameter of the crucible, and the crucible is put on the cylindrical tooling. However, if the shaped crucible shrinks, it will be difficult to remove it from the tooling. Utility Model Content

[0017] Embodiment 1

[0018] See also Figure 1-Figure 2 The present embodiment discloses an adjustable tooling for shaping a crucible, which is used for curing and shaping a crucible preform. The crucible preform involved in the present embodiment is in the shape of a tube with upper and lower openings, and the opening at one end is provided with a rib extending inwardly along the circumferential direction.

[0019] The adjustable tooling for shaping a crucible provided in this embodiment includes a supporting bottom plate 1 and a plurality of arc plates 2 arranged on the supporting bottom plate 1, wherein the arc plates 2 have a predetermined height, and the arc plates 2 are spliced ​​together to form a cylindrical shape, and the height of the arc plates 2 is set according to the height of the crucible product to be shaped.

[0020] In this embodiment, each arc-shaped plate 2 is constructed as a movable structure, and the diameter of the spliced ​​cylinder can be changed by synchronously retracting or expanding each arc-shaped plate 2.

[0021] Specifically, the adjustable tooling for shaping the crucible further includes a driving assembly for driving each curved plate 2 to move, the driving assembly includes a ball screw 3 connected to the supporting bottom plate 1, the ball screw 3 is arranged at the center of the cylinder of the curved plate 2, and the screw 31 is arranged vertically. The driving assembly also includes a support rod 4 connected between a nut end 32 of the ball screw 3 and the inner wall of the curved plate 2. By controlling the nut end 32 to move up and down, the curved plate 2 can be driven to perform synchronous inward or outward movement.

[0022] In this embodiment, one end of the screw 31 of the ball screw 3 is fixedly connected to the support base plate 1, that is, the screw 31 end of the ball screw 3 does not rotate, and the nut end 32 rotates relative to the screw 31. In order to prevent the rotation of the nut end 32 from driving the support rod 4 to twist, the drive assembly further includes a movable collar 5, which is sleeved on the periphery of the nut end 32 through a bearing. The movable collar 5 does not rotate with the nut end 32. The movable collar 5 can ensure that the support rod 4 moves up and down with the nut end 32 while not rotating therewith. One end of the support rod 4 is hinged to the movable collar 5, and the other end is hinged to the inner wall of the arc plate 2.

[0023] In order to facilitate the rotation of the nut end 32, a handle may be connected to the top surface of the nut end 32. The handle should have a sufficient height so that the staff can operate the crucible preform in the finalized state.

[0024] In order to ensure the movement stability of each curved plate 2, the adjustable tooling for shaping the crucible also includes a plurality of guide rails fixedly connected to the supporting bottom plate 1, each guide rail is arranged along the radial direction of the cylinder, and its number and position are matched with the curved plate 2, and the setting orientation of the guide rail is consistent with the support rod 4. A slider is fixedly connected to the bottom end of each curved plate 2, and the curved plate 2 is slidably connected to the guide rail through the slider. In this embodiment, by providing the guide rail and the slider, the curved plate 2 can be given a stable support and the movement stability of the curved plate 2 can be ensured.

[0025] When used, in the initial state, each curved plate 2 fits tightly, and the outer diameter of the cylinder of the curved plate 2 formed at this time is slightly smaller than the inner diameter of the crucible preform. The crucible preform is mounted on the cylinder tooling, and the retaining edge at one end of the crucible preform can be hung on the top of the curved plate 2. The nut end 32 of the ball screw 3 is rotated by an external force to raise it, and at the same time, each curved plate 2 is driven to move outward, thereby expanding the diameter of the cylinder of the curved plate 2, so that the outer wall of the cylinder of the curved plate 2 fits tightly to the inner wall of the crucible preform, which plays a role in supporting the shaping. At this time, the crucible is shaped to ensure that the shape of the crucible meets the product production requirements. After the shaping is completed, the nut end 32 of the ball screw 3 is rotated by an external force to lower its height, and the nut end 32 drives each curved plate 2 to move inward and tighten, thereby reducing the diameter of the cylinder of the curved plate 2. At this time, the shaped crucible can be easily removed from the cylinder of the curved plate 2.

[0026] Embodiment 2

[0027] The adjustable tooling for shaping the crucible provided in the second embodiment has substantially the same structure as the adjustable tooling for shaping the crucible provided in the first embodiment, and therefore, for the sake of brevity, only the differences are described in detail herein.

[0028] In this embodiment, the lead screw 31 of the ball screw 3 is rotatably connected to the support base plate 1, and the driving assembly further includes a driving member for driving the lead screw 31 to rotate. In this embodiment, the lead screw 31 passes through the support base plate 1 and is connected to the driving member. The driving member can adopt a manual driving structure, such as a crank, or an electric driving structure, such as a driving motor. The lead screw 31 is driven to rotate by the driving member, thereby driving the nut end 32 to move up and down.

[0029] In this embodiment, the movable collar 5 is directly sleeved on the nut end 32 , one end of the support rod 4 is hinged to the movable collar 5 , and the other end is hinged to the inner wall of the arc plate 2 .

[0030] The adjustable tooling for shaping the crucible provided by the utility model is easy to operate. By setting a cylindrical tooling formed by splicing multiple arc-shaped plates 2, and setting a driving component to synchronously control the orientation of the arc-shaped plates 2, the diameter of the cylindrical tooling is changed, so that it can be adapted to crucible preforms of different specifications. While supporting and shaping the crucible preform, the crucible preform can also be easily removed from the tooling.
