[0004] The existing titanium pipe reaming die and its equipment can only vertically place the die that needs to be reamed for reaming. The operation space is small, which cannot meet the reaming requirements of large titanium pipes. In the machining process, the titanium pipe being machined may vibrate or shake, affecting the size accuracy and quality of reaming. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a reaming equipment that can stably clamp the titanium pipe and uniformly ream, improving the size accuracy and quality of reaming.

[0006] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a titanium pipe reaming die, which comprises an operation table, a bottom plate fixedly connected to the operation table, a positioning device arranged on the bottom plate, clamping devices arranged on both sides of the positioning device, and a reaming die connected to one end of the clamping device.

[0007] The clamping device includes a buckle chuck, which is formed by hingedly connecting two clamping plates. A protective plate is hinged on the top of the clamping plate.

In the embodiments, the components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections; electrical connections; hydraulic connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0026] See Figure 1-6 As shown, the present invention provides a titanium tube reaming die, which includes: an operating table 11, a base plate 12 fixedly connected to the operating table 11, a positioning device 2 provided on the base plate 12, the positioning device 2 can adjust the position of the titanium tube in the vertical direction according to actual needs, one end of the positioning device 2 is connected to a clamping device 3, the clamping device 3 can provide a stable clamping force for the titanium tube, ensuring that the titanium tube will not be displaced or shaken during the reaming operation. The other end of the clamping device 3 is connected to the reaming die 46, and a hydraulic rod 46 is fixedly connected to the rear end of the reaming die 46. The hydraulic rod 46 provides power to the reaming die 46, pushing the reaming die 46 to reaming the titanium tube.

[0027] The operating table 11 consists of a table top and four legs. A base plate 12 is provided on the operating table 11. The base plate 12 is made of a rectangular metal material and is fixedly connected to the operating table 11 by bolts. A positioning device 2 is provided on the base plate 12. The positioning device 2 is on the same axis as the reaming die 46. The positioning device 2 includes two pads 21. The center of the pad 21 is provided with a V-shaped groove. The two pads are arranged along the central axis of the base plate. Before the reaming operation, the titanium tube needs to be placed in the V-shaped groove of the pad 21. Due to the special shape of the V-shaped groove, the titanium tube can be automatically centered in the groove, determining the approximate position of the titanium tube on the operating table 11. The pad 21 can support and position the cylindrical (or square) titanium tube. The pad 21 is fixedly connected to the base plate 12 by an electric push rod 22. The electric push rod 22 is vertically fixedly connected to the base plate 12. The electric push rod 22 can be vertically extended and retracted as needed, thereby driving the pad 21 to move vertically. When the height of the titanium tube needs to be adjusted, the electric push rod 22 is started to push the pad 21 to move vertically, adjusting the position of the titanium tube so that the central axis of the titanium tube is aligned with the central axis of the reaming die 46. When the position of the titanium tube is adjusted to the reaming position, the clamping device 3 must be used to fix the titanium tube.

[0028] A clamping device 3 is provided on both sides of the positioning device 2. The clamping device 3 includes two chucks, which are symmetrically distributed on both sides of the central axis of the reaming die 46. The chuck is hinged by two rectangular plate-shaped splints 31. A locking device is provided between the two splints 31. The two splints 31 can rotate relative to each other to adjust the clamping angle, and the angle between the two splints is fixed by the locking device to ensure that a stable clamping force can be provided when clamping titanium tubes of different sizes. This locking device can be a threaded rod. When it is a threaded rod, the threaded rod passes through the joint of the two splints 31 at the same time, and then a nut needs to be matched on the threaded rod. At this time, the splint 31 The side elevation of the clamp 31 is provided with ridges, while the nut of the threaded rod is provided with grooves. When the nut and the threaded rod are tightened, the ridges on the clamp 31 are stuck in the grooves on the nut. The top of the clamp 31 is hinged with a protective plate 34. The protective plate 34 has a certain deformation. In the non-clamped state, the protective plate 34 is a metal flat plate structure. A push rod 36 is fixedly connected to the middle position of the clamp 31. The push rod 36 contacts the middle position of the protective plate 34. An adjustment screw 35 is provided at one end of the clamp 31. The adjustment screw passes through the clamp 31 and is screwed to the clamp. The adjustment screw 35 can adjust the distance between one end of the protective plate 34 and the clamp 31. During the clamping process, when the protective plate 34 contacts the circular titanium tube, the protective plate 34 will be pressed into a curved shape to better fit the shape of the circular titanium tube. The push rod 36 will press against the middle position of the protective plate 34, causing the protective plate 34 to be excessively deformed.

[0029] The rear end of each chuck is fixedly connected to a cylinder 32. At this time, the cylinders 32 are also symmetrically distributed on both sides of the central axis of the reaming die 46, and the two cylinders 32 are relatively retractable. During the clamping process, the relative extension of the two cylinders 32 drives the splint 31 to move closer to the center to clamp the titanium tube. During the reaming process, the clamping device 3 always maintains a clamped state on the titanium tube to prevent the titanium tube from being displaced or shaken under the action of the reaming die 46. When the reaming is completed, the cylinder 32 is relatively retracted, and the splint 31 releases the titanium tube so that the processed titanium tube can be taken out. The cylinder 32 is fixedly connected to the base plate 12 through the cylinder 32 support seat, and the cylinder support seat 33 provides support for the operation of the cylinder 32. After the clamping is completed, the reaming die 46 can be operated to carry out reaming processing on the titanium tube.

[0030] The expansion die 46 includes two linear rails 41 fixedly connected to the base plate 12. The rails 41 extend along the length of the base plate 12 and are parallel to each other. A slide 42 is positioned above the rails 41. The slide 42 is a rectangular metal structure with a sliding structure at its bottom that mates with the rails 41, allowing the slide 42 to move horizontally along the rails 41. The rear end of the slide 42 is fixedly connected to a hydraulic rod 46, which is arranged horizontally with the rails 41. The extension and retraction of the hydraulic rod 46 provides the power for the horizontal movement of the slide 42 along the rails 41.

[0031] A mold shell 43 is fixedly connected to the top of the slide 42. The mold shell 43 is a rectangular structure as a whole, and its top is an arc shape. A rotatable core disk is assembled in the mold shell 43. The core disk is cylindrical, and a circular grinding disk is provided at the front end of the core disk. A mold core 44 is installed at the center of the core disk. The mold core 44 is conical or other shapes that may require reaming. Its shape and size determine the inner diameter of the titanium tube after reaming. The mold core 44 is fixedly connected to the core disk by bolts. The mold core 44 is convenient and detachable. When it is necessary to reame titanium tubes of different sizes, it is only necessary to disassemble and replace the mold core 44. After the titanium tube and the mold core 44 are docked and stably clamped, the hydraulic rod 46 is started, and the mold core 44 is pushed toward the titanium tube by the hydraulic rod 46. Under the action of the mold core 44, the inner diameter of the titanium tube gradually expands to achieve the purpose of reaming.

[0032] It should be noted that after the titanium tube undergoes the reaming operation, the inner tube mouth of the titanium tube may change unevenly or have burrs due to the squeezing with the mold core 44. Therefore, a motor 45 is connected to the rear end of the mold shell 43. The output shaft of the motor 45 is connected to the core disk through a coupling. When the reaming operation begins, the motor 45 is started to drive the mold core 44 to rotate. The rotation of the mold core 44 can make the reaming force act more evenly on the inner wall of the titanium tube. At the same time, when the titanium tube mouth contacts the grinding disc, the rotation of the core disk can drive the grinding disc to grind and process the tube mouth, making the tube mouth smoother and flatter, so that the processed titanium tube is more in line with the use requirements, and improving the quality and precision of titanium tube processing.

[0033] During the reaming process, friction between the mold core 44 and the titanium tube generates a certain amount of heat, necessitating cooling of the mold to prevent overheating and damage to the titanium tube, which could affect the quality of the titanium tube. Therefore, two cooling boxes 47 are fixedly attached to either side of the reaming mold 46. These cooling boxes 47 are fixedly attached to the slide 42, each connected to a water outlet pipe. The two cooling boxes 47 are symmetrically arranged about the central axis of the reaming mold 46. The cooling boxes 47 are filled with a water-soluble coolant, which has excellent cooling and lubricating properties. This water-soluble coolant cools and lubricates the surface of the titanium tube being processed.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based primarily on the scope of protection of the claims.
