Through the above method, this invention drives the pre-forging billet to rotate via a drive wheel, which can initially rotate the pre-forging billet on the arc plate to a set direction, facilitating the insertion of the square forming inner plate into the square through hole of the pre-forging billet, reducing manual labor. This invention, by setting a conical guide block, can further push the pre-forging billet to be aligned. This invention, by setting a quick-release structure, makes it easy to replace the forming die base, eliminating the need for a cumbersome disassembly process.

[0003] When using the aforementioned patent, the loading and unloading are done manually, which makes the processing efficiency easily affected by human intervention. This leads to a decrease in processing efficiency after a long period of processing. In addition, the patent does not provide tools for drilling and milling nickel alloy irregular parts, which means that other drilling and milling tools are required for processing nickel alloy irregular parts. Summary of the Invention

[0004] This invention provides a nickel-based alloy irregular part, its preparation method, and its drilling and milling equipment, aiming to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a nickel-based alloy irregular part is generally a cuboid, wherein two opposite sides are squares, and a through coaxial square hole is opened along the two squares, and a three-quarter cylinder protruding outward is provided along the four edges of the two squares.

[0006] This invention is achieved by a method for preparing a nickel-based alloy irregularly shaped part, comprising the following steps:

[0007] Step S1: Select raw materials and smelt them into round tube blanks, then cut the round tube blanks into sections and make square holes in the center to obtain the initial blank;

[0008] Step S2: The initial blank is transported to the drilling and milling equipment via a conveyor belt, heated first, then sent into a template for heating and extrusion molding, then taken out for drilling and milling, and then transported away via a conveyor belt.

[0009] Step S3: Finally, straighten and saw the parts to obtain the nickel-based alloy shaped parts.

[0010] This invention is implemented as follows: a milling and drilling device for nickel-based alloy irregular parts includes a forming assembly and a milling and drilling component, both installed in a housing. A rotary clamping assembly is provided on the outer side of the housing, and an extrusion assembly is provided directly opposite the entrance of the housing. The clamping assembly includes a turntable and a clamp mounted on the turntable. The clamp is provided with a stop foot and an automatically opening jaw. The stop foot cooperates with the jaw in the closed state to clamp the round tube blank, and the jaw in the open state is used to block the nickel alloy irregular part and release it from the extrusion assembly.

[0011] Preferably, the molding component includes a template, the cavity of which has the same shape as the nickel alloy profile. The template is detachably installed inside the housing, and the housing has heating zones installed at both the inlet and outlet of the template.

[0012] Preferably, an inner annular groove is provided at the entrance of the housing, and an electric rotating ring is installed in the inner annular groove. The drilling and milling parts are detachably installed on the rotating ring for drilling and milling of nickel alloy irregular parts.

[0013] Preferably, the extrusion assembly includes a hydraulic cylinder and a magnet plate installed at the output end of the hydraulic cylinder. A square tube is installed at the front end of the magnet plate, and a tapered head is provided at the front end of the square tube.

[0014] Preferably, the clamping assembly includes a mounting cylinder mounted on the side of the housing, one end of which is fitted with a turntable via a bearing, and a motor is disposed inside the mounting cylinder, the output shaft of which is fixed to the turntable.

[0015] Preferably, the outer wall of the turntable is provided with a plurality of frame-shaped clamps at equal intervals in a ring, and the internal size of the clamps is adapted to the size of the outer wall of the nickel alloy irregular part.

[0016] Preferably, the upper side of the clamp is provided with a sliding groove, in which the abutment and the gripper are slidably disposed respectively. The abutment and the gripper are pulled together along the sliding groove by a first spring. The inner side of the abutment is set in an arc shape, and the gripper is set in a semi-circular arc shape. Both the abutment and the gripper are adapted to the outer wall of the round tube blank.

[0017] Preferably, the gripper slides along the slide groove via a slide tube, the slide tube is provided with a limit rod inside, the gripper rotates along the annular groove opened in the slide tube, and the gripper is provided with a torsion spring inside. The gripper has inclined arc surfaces on both sides for pushing the limit rods on both sides to move outward and abut against the slide groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a nickel-based alloy shaped part, its preparation method, and its drilling and milling equipment. By installing a rotating clamping assembly at the entrance of the housing for loading and unloading, and cooperating with the extrusion assembly, the round tube blank can be fed into the housing for heating, extrusion molding, and drilling and milling operations, realizing fully automatic processing and preparation of nickel alloy shaped parts. The frame-type clamp in the clamping assembly can simply clamp the nickel alloy shaped part. The movable feet and jaws in the clamp, together with the clamp, can clamp and position the round tube blank, achieving the dual effect of clamping both the round tube blank and the nickel alloy shaped part. At the same time, since the jaws can rotate and unfold on their own, they can both block the finished meshing shaped part and detach it from the square tube to achieve the purpose of automatic unloading. At the same time, unfolding also facilitates the round tube blank to enter the clamp and be clamped, thus demonstrating the dual effect. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Please see Figure 1-5 The present invention provides a technical solution:

[0032] A nickel-based alloy irregular part is generally rectangular, with two opposite sides being squares, and a through-hole coaxial square hole is provided along the two squares. A three-quarter cylinder protruding outward is provided along the four edges of the two squares.

[0033] A method for preparing a nickel-based alloy irregularly shaped part includes the following steps:

[0034] Step S1: Select raw materials and smelt them into round tube blanks, then cut the round tube blanks into sections and make square holes in the center to obtain the initial blank;

[0035] Step S2: The initial blank is transported to the drilling and milling equipment via a conveyor belt, heated first, then sent into a template for heating and extrusion molding, then taken out for drilling and milling, and then transported away via a conveyor belt.

[0036] Step S3: Finally, straighten and saw the parts to obtain the nickel-based alloy shaped parts.

[0037] A milling and drilling device for nickel-based alloy irregular parts includes a forming component 2 and a milling and drilling component 3, both installed in a housing 1. A rotary clamping component 4 is provided on the outside of the housing 1. An extrusion component 5 is provided directly opposite the entrance of the housing 1. The clamping component 4 includes a turntable 42 and a clamp 44 mounted on the turntable 42. The clamp 44 is provided with a stop 45 and an automatically opening jaw 46. The stop 45 cooperates with the jaw 46 in the closed state to clamp the round tube blank. The jaw 46 in the open state is used to block the nickel alloy irregular part and remove it from the extrusion component 5.

[0038] In this embodiment, a rotating clamping assembly 4 is installed at the entrance of the housing 1 for loading and unloading. In conjunction with the extrusion assembly 5, the round tube blank can be fed into the housing 1 for heating, extrusion molding, and drilling and milling operations, thereby realizing the processing and preparation of nickel alloy irregular parts. The frame-type clamp 44 in the clamping assembly 4 can simply clamp the nickel alloy irregular parts. The two movable feet 45 and the jaws 46 in the clamp 44 can clamp and position the round tube blank, achieving the effect of fully automatic processing.

[0039] The molding component 2 includes a template 21, the cavity of which is the same as the shape of the nickel alloy irregular part. The template 21 is detachably installed in the housing 1. The housing 1 has heating zones 22 installed at the entrance and exit of the template 21.

[0040] It should be noted that a heating zone 22 is set at the entrance of the template 21 to heat and melt the round tube blank, so that the extrusion assembly 5 can extrude it into the template 21 to form a nickel alloy shaped part. At the same time, the heating zone 22 set at the exit is used to cooperate with the heating zone 22 at the entrance and plays an auxiliary role.

[0041] An inner ring groove 11 is provided at the entrance of the housing 1. An electric rotating ring 12 is installed in the inner ring groove 11. A drilling and milling part 3 is detachably installed on the rotating ring 12 for drilling and milling nickel alloy irregular parts.

[0042] It should be noted that the electric rotating ring 12 drives the drilling and milling part 3 to rotate around the nickel alloy irregular part, thereby realizing the drilling and milling treatment of the outer peripheral wall of the nickel alloy irregular part and ensuring the comprehensiveness of the drilling and milling process.

[0043] The extrusion assembly 5 includes a hydraulic cylinder 51 and a magnet 52 installed at the output end of the hydraulic cylinder 51. A square tube 53 is installed at the front end of the magnet 52, and a tapered head 54 is provided at the front end of the square tube 53.

[0044] It should be noted that the square tube 53 is compatible with the nickel alloy shaped parts and the square holes inside the round tube blanks, facilitating the forming of these holes. It also restricts the nickel alloy shaped parts and round tube blanks, preventing them from extending or retracting into the housing 1 and allowing rotation. This, combined with the template 21 and the milling machine 3, enables the processing of the nickel alloy shaped parts and round tube blanks. The conical head 54 facilitates the entry of the square tube 53 into the square holes inside the round tube blank, ensuring a smooth extrusion process. The magnetic piece 52 is used to magnetically attract the nickel alloy shaped parts, allowing them to be removed from the template 21 and housing 1 when the hydraulic cylinder 51 retracts, for discharge.

[0045] The clamping assembly 4 includes a mounting cylinder 41 mounted on the side of the housing 1. One end of the mounting cylinder 41 is mounted with a turntable 42 via a bearing. A motor 43 is installed inside the mounting cylinder 41, and the output shaft of the motor 43 is fixed to the turntable 42. Multiple frame-shaped clamps 44 are evenly spaced in a ring on the outer wall of the turntable 42. The internal size of each clamp 44 is adapted to the outer wall size of the nickel alloy shaped part. A sliding groove 441 is provided on the upper side of each clamp 44. A foot 45 and a jaw 46 are slidably disposed in the sliding groove 441. The foot 45 and the jaw 46 are pulled together along the sliding groove 441 by a first spring 47. The inner side of the foot 45 is arc-shaped, and the jaw 46 is semi-arc-shaped. Both the foot 45 and the jaw 46 are adapted to the outer wall of the round tube blank. The gripper 46 slides along the slide groove 441 via the slide tube 461. The slide tube 461 is provided with a limit rod 462 inside. The gripper 46 rotates along the annular groove 463 opened in the slide tube 461. The gripper 46 is equipped with a torsion spring 464. The gripper 46 has inclined arc surfaces on both sides to push the limit rods 462 on both sides to move outward and abut against the slide groove 441.

[0046] Furthermore, since the fixture 44 is frame-shaped and its internal size is the same as the outer wall size of the nickel alloy shaped part, the nickel alloy shaped part can be directly moved into the fixture 44 for clamping after it is processed, without the need for other clamping methods. Sliding feet 45 and grippers 46 are provided inside the fixture 44, and a first spring 47 is provided between them to pull them together. This design, combined with the fact that the inner wall of the feet 45 is a small arc and the grippers 46 are semi-circular, allows for clamping and positioning of the round tube blank from two opposite directions. This prevents the round tube blank from rotating in the fixture 44 or from shifting its position as the fixture 44 rotates with the turntable 42, ensuring that the round tube blank is aligned and positioned with the inlet of the shell 1 and the square tube 53 of the extrusion assembly 5. Inside the slide tube 461, a torsion spring 464 and a gripper 46 are installed. The gripper 46, without external force, is driven outward by the torsion spring 464. On one hand, the short end of the rotated gripper 46 is positioned inside the clamp 44, thus blocking the processed nickel alloy shaped part and detaching it from the square tube 53. On the other hand, the outward opening facilitates the guidance of the round tube blank after rotation, allowing it to enter the clamp 44. Simultaneously, it facilitates the compression of the short end of the round tube blank, allowing the clamp 44 to rotate and retract, holding the round tube blank. During the rotation and unfolding process, the gripper 46 compresses the limiting rod 462 through its inclined arc surfaces on both sides, causing the limiting rod 462 to move outward along the slide tube 461 and compress and lock the outer wall of the slide groove 441, preventing the first spring 47 from pulling back to its original position. This, combined with the unfolded state of the gripper 46, facilitates the guidance of the round tube blank into the clamp 44 for holding.

[0047] The specific working principle and usage process of the milling and drilling equipment for nickel-based alloy irregular parts are as follows: First, start the motor 43 to drive the turntable 42 to rotate. The rotation of the turntable 42 clamps the round tube blank on the conveyor belt through the clamp 44. When clamping the round tube blank, the round tube blank squeezes the inner short end of the clamp 46, and at the same time squeezes the torsion spring 464, so that the outer long end of the open clamp 46 is squeezed and rotates to clamp the round tube blank. At the same time, due to the rotation of the clamp 46, the two limit rods 462 are not squeezed, so the limit rods 462 separate from the side wall of the slide 441 and are retracted into the slide tube 461. The slide tube 461, under the pull of the first spring 47, is connected to the foot 45. The round tube blank is clamped and positioned from both sides along the slide groove 441. Then, when the turntable 42 rotates the clamp 44 upwards, the round tube blank is aligned with the inlet of the housing 1 and also with the square tube 53 of the extrusion assembly 5. The hydraulic cylinder 51 is then activated to extend the square tube 53, which enters the square hole of the round tube blank until the magnet 52 is in contact with one end of the round tube blank. The extension continues, pushing the round tube blank into the housing 1. Since the round tube blank has detached from the clamp 44, the inner side of the gripper 46 is no longer compressed, causing the gripper 46 to expand outwards under the action of the internal torsion spring 464. Simultaneously, as the round tube blank detaches, it is also affected by this expansion, partially extending along the slide groove 441. As the gripper 46 expands outward, the limiting rod 462 re-engages with the inside of the slide groove 441, locking the position of the slide tube 461 and simultaneously locking the position of the gripper 46. The round tube blank is fed into the heating zone 22 by the extrusion assembly 5 for heating, causing a certain degree of melting of the outer wall. Then, the round tube blank is directly fed into the template 21 for extrusion molding. After cooling and molding in the template 21, a nickel alloy shaped part blank is formed. Due to the action of the magnet 52, when the hydraulic cylinder 51 retracts, the square tube 53 and the magnet 52 carry the nickel alloy shaped part blank out for machining in the drilling and milling area. The drilling and milling part 3 is rotated by the rotating ring 12. The nickel alloy shaped part is drilled and milled in all directions. Then, the hydraulic cylinder 51 continues to retract, and one end of the nickel alloy shaped part enters the fixture 44. At the same time, it is blocked by the short end of the inside of the unfolded jaw 46 and cannot move forward. At this time, the nickel alloy shaped part is separated from the housing 1. The hydraulic cylinder 51 continues to retract and separates the square tube 53 from the processed nickel alloy shaped part. Finally, the motor 43 is started to drive the turntable 42 to continue to rotate. The fixture 44 moves the nickel alloy shaped part away from the entrance of the housing 1. At the same time, after rotating ninety degrees, it falls from the fixture 44 onto the conveyor belt. Meanwhile, the fixture 44 continues to move with the turntable 42 to clamp another round tube blank on the conveyor belt for processing the next nickel alloy shaped part.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
