Description

Technical Field

[0001] The utility model relates to the technical field of cake material processing, in particular to a cake material arc surface processing device. Background Art

[0002] Titanium alloy has good comprehensive properties such as high strength, high toughness and corrosion resistance, and is mainly used in aerospace, ships, weapons and other fields. The main processing methods for titanium alloy cakes are forging and rolling. After ordinary titanium alloy cakes are forged and rolled into finished products, although conventional machining and peeling can meet the standard requirements, conventional machining cannot meet the requirements of Nb-Ti alloy (Nb content 45-55% / wt) cakes used in the superconducting field with high requirements for flatness and smoothness. For example, when polishing the arc surface of the cake, in order to fix the cake, it is necessary to first punch a hole in the center of the cake so that the top of the machine tool will not slide with the cake, and then fix the other side of the cake on the three-jaw chuck of the machine tool, and fix the cake by squeezing the three-jaw chuck and the top pin on both sides of the cake, and then control the three-jaw chuck to drive the cake to rotate, and polish the arc surface of the cake under the action of the polishing tool. This method will damage the surface of the cake material. During the extrusion process, the contact area between the cake material and the three-jaw chuck and the center is small, and the cake material is prone to deformation, which affects the final flatness of the cake material. Summary of the invention

[0003] In view of this, it is necessary to provide a cake material arc surface processing device which does not damage the cake material surface and is not prone to deformation during the processing process.

[0004] A cake material arc surface processing device comprises a top, an organic plug, a metal plug and a three-jaw chuck. A conical hole is provided on one side of the organic plug, and the top can be engaged and connected with the conical hole of the organic plug. The other side of the organic plug is provided with anti-slip grooves to increase the friction between the cake material and the organic plug. One side of the metal plug is engaged and connected with the three-jaw chuck, and the other side of the metal plug is provided with sandpaper, which is bonded to the metal plug. During processing, the cake material is clamped between the organic plug and the metal plug.

[0005] Preferably, the material of the organic plug is nylon.

[0006] Preferably, the metal plug is made of titanium alloy, and the diameter of the metal plug is smaller than the diameter of the cake material.

[0007] Preferably, the anti-slip pattern of the organic plug is an annular water pattern.

[0008] Preferably, a guide rail is provided at the bottom of the three-jaw chuck to facilitate adjustment of the distance between the three-jaw chuck and the top.

[0009] Beneficial effects: When the cake material arc surface processing device of the utility model is in use, the organic plug is installed on the top, and the metal plug is installed on the three-jaw chuck. The top and the three-jaw chuck are gradually brought closer, so that the cake material is clamped between the organic plug and the metal plug. The contact surface between the organic plug and the metal plug and the cake material is larger. At the same time, the contact surface between the organic plug and the cake material is provided with anti-slip grooves, and the contact surface between the metal plug and the cake material is provided with sandpaper, which can effectively increase the friction force, and the cake material is less likely to slide and be scratched. The pressure on both sides of the cake material is more uniform, and the cake material is less likely to deform. The arc surface of the cake material is then polished by a tool.

[0014] In the figure: a cake material arc surface processing device 10, a top 20, an organic plug 30, an anti-slip pattern 301, a tapered hole 302, a metal plug 40, a three-jaw chuck 50, and a guide rail 501. DETAILED DESCRIPTION

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0016] Please see Figures 1 to 4 A cake material arc surface processing device 10 includes a top 20, an organic plug 30, a metal plug 40, and a three-jaw chuck 50. A conical hole 302 is provided on one side of the organic plug 30, and the top 20 can be engaged with the conical hole 302 of the organic plug 30. The other side of the organic plug 30 is provided with an anti-slip pattern 301 to increase the friction between the cake material and the organic plug 30. One side of the metal plug 40 is engaged with the three-jaw chuck 50, and the other side of the metal plug 40 is provided with sandpaper, which is bonded to the metal plug 40. During processing, the cake material is clamped between the organic plug 30 and the metal plug 40.

[0017] The utility model aims at the problem that the cake material structure is damaged, easily scratched and deformed when the three-jaw chuck 50 and the top 20 clamp the cake material. By adding an organic plug 30 and a metal plug 40 on both sides of the cake material, and setting an anti-slip pattern 301 on one side of the organic plug 30, and setting sandpaper on one side of the organic plug 30, the cake material is less likely to slide, the processing accuracy is higher, and the cake material structure is not damaged. At the same time, the contact surface between the organic plug 30 and the metal plug 40 and the cake material is larger, the pressure per unit area is smaller, and the cake material is less likely to deform.

[0018] In order to ensure the accuracy during the processing, after the cake material is fixed, the cake material is fine-tuned by a dividing ruler so that the cake material, the organic plug 30 and the metal plug 40 remain coaxial.

[0019] The organic plug 30 is provided to facilitate the processing of the tapered hole 302 and the anti-slip pattern 301, and the friction coefficient with the cake material is also greater, and the cake material is less likely to slide. The material of the organic plug 30 can be resin or plastic. In a preferred embodiment, the material of the organic plug 30 is nylon.

[0020] The metal plug 40 has a relatively high strength, is not easily deformed when the three-jaw chuck 50 is clamped, and the edge of the plug is not easily damaged. At the same time, the metal material is heavier, and the rotation process is more stable. The material of the metal plug 40 depends on the material of the cake material to be processed. The utility model is mainly aimed at Nb-Ti alloy, so in a preferred embodiment, the material of the metal plug 40 is titanium alloy, and the diameter of the metal plug 40 is smaller than the diameter of the cake material.

[0021] The diameter of the metal plug 40 is smaller than the diameter of the disc material, so that when the arc surface of the disc material is polished, there will be no interference with the metal plug 40 .

[0022] Considering that the cake material is subjected to the centrifugal force during the rotation process, the greater the deviation of the cake material center, the greater the centrifugal force, and the easier it is for the cake material to slide. In a preferred embodiment, the anti-slip pattern 301 of the organic mandrel 30 is an annular water pattern. On the one hand, the annular water pattern can play a positioning role, so that the center of the cake material is coaxial with the center of the organic mandrel 30. On the other hand, the centrifugal force is perpendicular to the direction of the annular water pattern, which can play a better anti-slip role.

[0023] Because the cake material needs to be clamped, the distance between the three-jaw chuck 50 and the top 20 needs to be adjusted.

[0024] In a preferred embodiment, a guide rail 501 is provided at the bottom of the three-jaw chuck 50 to facilitate adjustment of the distance between the three-jaw chuck 50 and the center 20 .

[0025] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
