Description

Technical Field

[0001] The utility model relates to the technical field of core wire processing, in particular to a spiral shaping mechanism. Background Art

[0002] Core wire, as a thin, flexible and strong linear or ribbon material, has been widely used in the field of vascular intervention due to its unique physical properties. This material can be finely manufactured using a variety of different materials according to specific medical needs, thereby ensuring the best performance and effect during vascular intervention surgery.

[0003] The shaping process of traditional core wire mainly relies on manually winding the core wire on the shaping rod to form a spiral shape, and then sending it into the heat treatment furnace for shaping. Although this method meets the production needs to a certain extent, during the heat treatment process, the core wire may produce different stresses at different positions due to different winding tightness and inconsistent winding methods. When these core wires are heated, the uneven stress distribution will cause the core wires in certain areas to be more easily deformed, thus affecting the quality of the product.

[0004] Therefore, a spiral shaping mechanism with high processing accuracy is needed to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] The utility model provides a spiral shaping mechanism, such as Figure 1-Figure 3 As shown, the spiral shaping mechanism includes a base 1, a bearing plate 2 arranged on the base 1, a spiral groove 21 opened on the bearing plate 2 for accommodating a core wire, a cover plate 3 snapped into a position on the base 1 corresponding to the spiral groove 21, and a fastening bolt 4 arranged on the cover plate 3. The base 1, the bearing plate 2 and the cover plate 3 are fixedly connected by the fastening bolts 4; a movable structure 12 for connecting the cover plate 3 is arranged on one side of the base 1 close to the cover plate 3.

[0030] When in use, the core wire to be processed is placed in the spiral groove 21 along the shape of the spiral groove 21, and then the cover plate 3 is moved to the spiral groove 21 through the connection of the movable structure 12, and covers the surface of the core wire placed in the spiral groove 21. Next, the fastening bolts 4 are passed through the corresponding holes of the base 1 and the supporting plate 2, and the fastening bolts 4 are rotated so that the fastening bolts 4 are screwed downward into the base 1 until they are fully tightened, and the tight connection between the cover plate 3 and the base 1 and the supporting plate 2 is ensured, and then the entire spiral shaping device is placed in a heat treatment furnace for heat treatment and shaping. After completing the core wire shaping process, it is only necessary to loosen the fastening bolts 4, release the connection between the cover plate 3 and the base 1 and the supporting plate 2, and then move the cover plate 3 away from the spiral groove 21 through the connection of the movable structure 12, so that the shaped core wire can be taken out of the spiral groove 21.

[0031] Specifically, the movable structure 12 includes a rotating shaft 121 which longitudinally penetrates the base 1 near the side of the cover plate 3 and is rotatably connected to the base 1, and a sleeve block 122 which is fixedly sleeved on the rotating shaft 121 and is fixedly connected to one side of the cover plate 3;

[0032] When the core wire to be processed is placed in the spiral groove 21 and needs to be covered with the cover plate 3, since the cover plate 3 is connected to the rotating shaft 121 through the sleeve block 122, and the rotating shaft 121 is rotatably connected to the base 1, when the cover plate 3 is needed to cover the core wire to be processed, the cover plate 3 can be quickly moved to the spiral groove 21 to cover the core wire by simply rotating it. When the core wire is processed, the connection between the cover plate 3 and the base 1 and the supporting plate 2 is released, and the cover plate 3 can be easily moved away from the spiral groove 21 to one side of the base 1 by simply rotating it. In daily use, the entire spiral device can be easily stored and used by simply connecting the rotating shaft 121 and the sleeve block 122, without the need to store a single structure to avoid loss.

[0033] Among them, in order to facilitate the operation of the fastening bolt 4, a knob 41 is fixedly installed at one end of the fastening bolt 4 away from the base 1, the bearing plate 2 and the cover plate 3; the design of the knob 41 allows the operator to tighten or loosen the fastening bolt 4 through a simple rotation action without using other tools, which greatly improves the convenience of operation, reduces the operating steps, and saves time.

[0035] Different from the first embodiment, in order to improve the adaptability and versatility of the device, a slot 11 is provided at the position of the base 1 corresponding to the bearing plate 2, the bearing plate 2 is clamped in the slot 11, and connecting bolts 23 are provided at the corners around the bearing plate 2, and the bearing plate 2 is fixedly connected to the slot 11 through the connecting bolts 23;

[0036] First, select a suitable and corresponding carrier plate 2 according to the specifications of the core wire to be processed, then place the carrier plate 2 in the slot 11, and further fix the carrier plate 2 to the slot 11 and the base 1 through the connecting bolts 23. Then, place the matching core wire to be processed along the spiral groove 21 set on the carrier plate 2. If it is necessary to process the next batch of core wires of the same specification, it is only necessary to loosen the connecting bolts 23 to release the connection between the carrier plate 2 and the slot 11, and then replace the carrier plate 2 with the spiral groove 21, and then fix it with the connecting bolts 23. If the carrier plate 2 is worn, it can also be replaced by disassembling the carrier plate 2.

[0037] In addition, in order to avoid affecting the use of the cover plate 3, a threaded hole 22 is provided at the position of the supporting plate 2 corresponding to the connecting bolt 23, and the connecting bolt 23 is located in the threaded hole 22; the connecting bolt 23 is arranged in the threaded hole 22, which can prevent the bottom of the cover plate 3 from contacting the top of the connecting bolt 23 and affecting the tightness of the connection between the cover plate 3 and the base 1 and the supporting plate 2, and at the same time ensure that the connecting bolt 23 can be accurately aligned and fixed on the slot 11.
