Description

Technical Field

[0001] This utility model relates to the technical field of sleeve shell and supporting core material separation equipment, specifically a device for separating sleeve shell and supporting core material. Background Technology

[0002] The cannula shell is a cylindrical shell, such as the cannula shell of an interventional blood pump. It is a thin-walled, compact alloy cannula with a diameter of 2-8 mm. During production, it is first machined using a machining center. During heat treatment, to prevent deformation, a high-temperature resistant cylindrical material matching its inner diameter is inserted into the cannula shell. This high-temperature resistant cylindrical material is called the support core material, such as a ceramic rod. The cannula shell and support core material are then placed together in an annealing furnace for heat treatment. After heat treatment and cooling to room temperature, the support core material needs to be extracted from the cannula shell. Traditionally, this is done manually, which easily leads to cannula shell deformation. Ejection using tooling is also possible, but current ejection tooling typically only allows for the separation of cannula shells of one diameter per mold. If the cannula shell diameter changes, a new mold needs to be used, resulting in high costs. Therefore, an improved technology is urgently needed to solve this problem in the existing technology.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a device for separating the casing and the supporting core material, including a frame, a pushing mechanism, a polygonal mold and a mold clamping assembly;

[0029] The frame includes a base 1, a column 2, a cross block 3, and a pressure rod 4. The column 2 is vertically mounted on the upper surface of the base 1. The cross block 3 is mounted on the column 2. A fastening bolt 25 is provided on one side of the cross block 3. The fastening bolt 25 is fastened to the column 2 to fix the cross block 3 and adjust its height. A guide groove 29 is provided on one side of the column 2. The cross block 3 is guided to the column 2 through a guide hole. A guide block 30 is provided in the guide hole of the cross block 3. The guide block 30 is slidably engaged with the guide groove 29. This structure prevents the cross block 3 from rotating, thereby ensuring that the push rod 11 is engaged with the corresponding mold hole 18 of the polygonal mold. A shaft 5 is provided inside the cross block 3. One end of the shaft 5 is connected to the pressure rod 4. A gear 6 is also provided inside the shaft 5. The base 1 has a shaft hole 7. Several anti-slip feet 28 are provided on the lower surface of the base 1 to achieve overall anti-slip and support.

[0030] The pushing mechanism includes a lifting rod 8, a clamp 10, and a push rod 11. The lifting rod 8 slides through the horizontal block 3. A groove is provided on the side of the lifting rod 8 near the gear 6. A rack 12 is provided in the groove of the lifting rod 8. The side of the gear 6 near the lifting rod 8 extends into the groove and meshes with the rack 12. A connecting seat 13 is provided at the bottom of the lifting rod 8. A clamp 10 is provided at the bottom of the connecting seat 13. The top of the push rod 11 is fastened to the clamp 10. A limit cap 26 is provided at the top of the lifting rod 8. A spring 9 is sleeved on the lifting rod 8. The two ends of the spring 9 are respectively connected to the limit cap 26 and the upper surface of the horizontal block 3. The spring 9 allows the lifting rod 8 to automatically lift after use by the elastic force of the spring 9, improving convenience.

[0031] The polygonal mold includes a template 14, support rods 15, support base 16, and central shaft 17. The lower surface of the template 14 is connected to the support base 16 by several support rods 15. A central shaft 17 is set at the center of the lower surface of the support base 16. The central shaft 17 passes through the shaft hole 7 of the base 1. The bottom of the central shaft 17 is threaded and is limited by a nut 24. The base 1 is provided with a groove below the shaft hole 7. The nut 24 is set in the groove to realize the setting and installation of the nut 24. The template 14 and the support base 16 are both regular polygons. The template 14 is provided with several mold holes 18 of different sizes in a ring with the central shaft 17 as the center. The inner wall of each mold hole 18 is provided with a boss 19. The position of the push rod 11 corresponds to the position of one of the mold holes 18. When the polygonal mold rotates and is clamped by the mold clamping assembly, one of the mold holes 18 is located directly below the push rod 11.

[0032] Two mold clamping assemblies are symmetrically arranged on the upper surface of the base 1. The mold clamping assemblies include a vertical plate 20, an internal threaded sleeve 21, and a push screw 22. The vertical plate 20 is connected to the upper surface of the base 1. The vertical plate 20 has a through hole and the internal threaded sleeve 21 is located at the through hole. The push screw 22 cooperates with the internal threaded sleeve 21. The inner end of the push screw 22 is provided with a top block 23. The top block 23 cooperates with the outer surface of the support seat 16. Reinforcing plates 27 are also provided on both sides of the vertical plate 20 to ensure the structural strength of the vertical plate 20.

[0033] Assembly method and operating principle: Place the spring 9 onto the lifting rod 8, and pass the lifting rod 8 through the horizontal block 3. During insertion, the groove of the lifting rod 8 engages with the gear 6 until the rack 12 area meshes with the gear 6. Then, connect the connecting seat 13 with the chuck 10 to the bottom of the lifting rod 8, and then secure the top of the push rod 11 to the chuck 10. Connect the horizontal block 3 to the column 2, and connect it to the guide groove 29 of the column 2 via the guide block 30 to ensure that the horizontal rod does not rotate around the column 2, thus ensuring that the push rod 11 fits perfectly with the mold hole 18 of the polygonal mold. Pass the central shaft 17 at the bottom of the polygonal mold through the shaft hole 7 of the base 1. Connect the bottom of the central shaft 17 to the nut 24 and limit its position with the nut 24 to complete the assembly. In use, select the appropriate mold hole 18 according to the size of the sleeve housing. Rotate the polygonal mold so that the corresponding mold hole 18 is directly below the push rod 11, then rotate the push screw 22 so that the two top blocks 23 respectively abut against the two sides of the support base 16 to complete the fixation of the polygonal mold. The sleeve housing, internally supported by ceramic pillars, is inserted into the die hole 18. At this time, the bottom of the sleeve housing is supported on the boss 19 of the die hole 18. Figure 6As shown, the downward pressing rod 4, through the cooperation of gear 6 and rack 12, causes the lifting column to descend. The push rod 11 abuts against the ceramic column and drives the ceramic column to press down, causing the ceramic column to detach from the sleeve shell, thus completing the separation of the sleeve shell and the supporting core material. The ceramic column leaves the mold hole 18 and falls onto the support base 16. This utility model has a reasonable structure. The polygonal mold is supported on the upper surface of the base 1 by the central shaft 17. The template 14 has several mold holes 18 of different sizes. The inner wall of each mold hole 18 is provided with a boss 19 to facilitate the support of the sleeve shell. Through the cooperation of gear 6 and rack 12, the downward pressing rod 4 can drive the lifting rod 8 to descend. The push rod 11 pushes out the supporting core material inside the sleeve shell, greatly improving convenience and efficiency. It will not cause damage or deformation to the sleeve shell during separation. At the same time, since the polygonal mold can rotate, it is clamped on both sides by the mold clamping assembly. The mold hole 18 can be switched directly without changing the mold, greatly improving convenience. It can also be applied to various sleeve shells of different sizes, greatly expanding the scope of application and reducing costs.
