Abstract
Description
Technical Field
[0001] This utility model relates to metal parts cutting equipment, specifically an axial cutting assembly for ultra-thick wall heat-resistant alloy parts. Background Technology
[0002] When processing various ring-shaped steel parts, these parts typically require cutting tests or slicing separation. However, due to differences in materials and wall thicknesses, the cutting process varies. For parts with a wall thickness of less than 100mm, we can use conventional grooving tools or manual cutting tools for simple cutting, and the process is not complicated. However, when dealing with large parts with wall thicknesses of 200-400mm, especially high-temperature alloys, titanium alloys, and other heat-resistant alloys, cutting becomes very difficult. First, because their wall thickness is too large, we need corresponding long-stroke cutting tool assemblies; second, due to their large wall thickness, deformation may occur during cutting, causing the tool to jam, so we also need scientific cutting techniques and methods.
[0003] Based on the issues raised above, our company independently developed a cutting assembly that meets the requirements, and combined it with optimized cutting technology to successfully achieve ultra-thick wall cutting of large alloy rings. This achievement not only allowed us to accumulate professional knowledge in the cutting field and reduce product quality issues, but also improved our production efficiency. Utility Model Content
[0004] The purpose of this utility model is to overcome the above-mentioned technical difficulties and provide an axial cutting assembly for ultra-thick wall heat-resistant alloy parts.
[0005] To achieve the above objectives, the technical solution adopted is as follows: A machine tool rotary table is included, the surface of which is provided with a clamping fixture. The clamping fixture holds a part. Two worktables are respectively provided on both sides of the machine tool rotary table. Each worktable is provided with a lifting mechanism. The lifting end of the lifting mechanism is provided with a pushing mechanism. The pushing end of the pushing mechanism is connected to a base. Two bases are respectively provided with a long-stroke cutting tool assembly and a short-stroke cutting tool assembly on the side closest to the part. Each base includes a tool-holding assembly. Both the short-stroke and long-stroke tool assemblies include a cutting head and a cutting body. The cutting heads are flat, and their top surfaces are also flat. The ends of the cutting bodies of the short-stroke and long-stroke tool assemblies furthest from the part are fixedly connected to the base, including the tool-holding assembly.
[0006] Furthermore, the clamping fixture includes a four-jaw clamp, and the outer wall of the part is clamped within the four-jaw clamp.
[0007] Furthermore, the long-stroke blade assembly has a clamping member on the middle section surface of the blade body, which is fixedly connected to the clamping blade assembly.
[0008] Furthermore, a stabilizing part is sleeved on the surface of the long-stroke blade assembly. The stabilizing part includes multiple guide rods arranged horizontally to each other on the outer wall of the blade body. Foam cotton is held between the guide rods. The distance between the inner wall of the foam cotton and the blade body is 0.05-0.1mm. Fixing heads are fixedly connected to both ends of the multiple guide rods. A sleeve is fixedly sleeved on the outer wall of the multiple guide rods. A connecting rod is fixedly connected to the lifting end of the lifting mechanism.
[0009] Furthermore, the propulsion mechanism is an electric push rod disposed on the surface of the lifting mechanism. The electric push rod includes a base and a push rod. The outer wall of the sleeve is provided with a horizontal and protruding slide rod. The outer wall of the base is fixedly provided with a sliding box that slides and connects with the outer wall of the slide rod on the outer wall of the sleeve at one end near the sleeve. A spring is provided between the inner wall of the sliding box near the part end and the slide rod. A connecting rod is fixedly connected between the sleeve and the lifting mechanism. The sleeve is provided with a downwardly extending push plate at the end away from the part. The base of the long stroke tool assembly is provided with a push rod that is horizontally disposed corresponding to the position of the push plate.
[0010] Furthermore, the distance between the push rod and the push plate is 2-5cm.
[0011] Furthermore, the blade is made of a heat-resistant and wear-resistant material.
[0012] The beneficial effects of adopting the above scheme are as follows: When using this axial cutting assembly for ultra-thick wall heat-resistant alloy parts, the part to be cut is first placed in the clamping fixture and clamped stably. Then, a short-stroke cutter is used in conjunction with a long-stroke cutter. The short-stroke cutter first cuts the inner and outer diameter grooves at the end of the part, and the long-stroke cutting assembly cuts the cut inner and outer diameter grooves respectively. Finally, when approaching the cut-off point, the rotation speed of the part is reduced, and the machine tool is stopped and the part is removed. Through the cooperation between the cutting assemblies, the mature process flow, and the stable process parameters, an effective ultra-thick wall heat-resistant alloy cutting assembly is formed.

Detailed Implementation
[0021] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0022] Example 1
[0023] An axial slitting and cutting assembly for ultra-thick wall heat-resistant alloy parts includes the following steps:
[0024] ① Place the part 5 to be cut on the machine tool turntable 9, fix it with a clamping fixture, and use a variety of cutting tools to cut it;
[0025] ② Use the short-stroke cutting tool assembly 7 from a variety of cutting tools to cut the inner and outer diameter slots at the ends of part 5;
[0026] ③ Use the long-stroke cutter assembly 12 to cut the groove on the outer diameter of part 5 in step ②;
[0027] ④ Use the long-stroke cutter assembly 12 to cut from the slot in the inner diameter of part 5 in step ②;
[0028] ⑤ When approaching the cut-off point, reduce the rotation speed of the part by 5 and closely monitor the cutting status;
[0029] ⑥ When the cutting part 5 is separated, stop the machine tool turntable 9 in time and remove part 5.
[0030] In the above methods, such as Figure 1The machine tool turntable 9 has two worktables on each side. Each worktable has a lifting mechanism 8. The lifting end of the lifting mechanism 8 has a pushing mechanism. The pushing end of the pushing mechanism is connected to a base. The two bases have a long-stroke cutter assembly 12 and a short-stroke cutter assembly 7 on the side near the part 5, respectively.
[0031] In specific implementation, the clamping fixture includes a four-jaw clamp 4, and the outer wall of the part 5 is clamped within the four-jaw clamp 4.
[0032] In a specific implementation, the base includes a blade clamping assembly 6. Both the short-stroke blade assembly and the long-stroke blade assembly include a blade head 14 and a blade body 13. The blade heads 14 are all flat, and the top surface of the blade head 14 is also flat. The end of the blade body 13 of the short-stroke blade assembly and the long-stroke blade assembly away from the part 5 is fixedly connected to the base including the blade clamping assembly 6.
[0033] In specific implementation, the blade body 13 of the long-stroke blade assembly is provided with a clamping member 11 on the middle section surface, which is fixedly connected to the clamping blade assembly 6.
[0034] Meanwhile, during implementation, the cutting thickness of part 5 can be further controlled by adjusting the height and pushing length of the lifting mechanism 8 and the pushing mechanism according to the height and cutting thickness of part 5.
[0035] The clamping component 6 of the base is a conventional clamping component in the prior art. It is simply a matter of clamping the cutting blade. The blade head 14 and the blade body 13 are flat, which makes it convenient for the blade body 13 to perform flat cutting on the cutting surface of the part 5 during cutting.
[0036] The specific implementation method is as follows: When using this axial cutting assembly for ultra-thick wall heat-resistant alloy parts 5, the part 5 to be cut is first placed in the four-jaw clamp 4 of the clamping fixture and clamped stably. Then, a short-stroke cutter is used in conjunction with a long-stroke cutter. The short-stroke cutter first cuts the inner and outer diameter grooves at the end of the part 5. The long-stroke cutter assembly 12 cuts the cut inner and outer diameter grooves respectively. Finally, when approaching the cut-off point, the rotation speed of the part 5 is reduced. Finally, the machine tool is stopped and the part 5 is removed. Through the cooperation between the cutter assemblies, the mature process flow and stable process parameters, an effective ultra-thick wall heat-resistant alloy cutting assembly is formed.
[0037] Example 2
[0038] Based on Embodiment 1, the applicant considered that, sometimes the thickness of the part 5 being cut is large, and the long-stroke cutting tool assembly 12's cutting head 14 and blade, due to the relatively long blade body 13, are prone to instability when the cutting tool penetrates deep into the part 5. Therefore, regarding this phenomenon, as... Figure 2 , Figure 5 and Figure 6The applicant has fitted a stabilizing part onto the surface of the long-stroke blade assembly. The stabilizing part includes multiple guide rods 10 arranged horizontally to each other on the outer wall of the blade body 13. Foam cotton 3 is held between the guide rods 10. The distance between the inner wall of the foam cotton 3 and the blade body 13 is 0.05-0.1mm. Fixing heads are fixedly connected to both ends of the multiple guide rods 10. A sleeve 15 is fixedly sleeved on the outer wall of the multiple guide rods 10. A connecting rod 16 is fixedly connected to the lifting end of the lifting mechanism 8.
[0039] With this setting, when the long-stroke cutter assembly is cutting part 5, even if the pusher assembly pushes the long-stroke cutter assembly 12 into part 5, the stabilizing unit can reduce cutting vibration. The foam cotton 3 distributed between the guide rods 10 on the outer wall of the blade body 13 in the stabilizing unit can reduce vibration. At the same time, the guide rods 10 can transmit the vibration effect of the cutting force received by the cutter head 14 to the entire blade body 13, thereby reducing the impact of the cutting force on the blade body 13 and the cutter head 14 and stabilizing the cutting effect.
[0040] Example 3
[0041] Based on Embodiment 2, in order to further enhance the stability of the long-stroke cutter assembly 12, the applicant, such as... Figure 3 The sleeve 15 is fixedly connected to the lifting end of the lifting mechanism 8 and the base 1 end of the propulsion part by a connecting rod 16, which further enhances the stability of the stabilizing part.
[0042] Example 4
[0043] Based on Embodiments 3 and 2, the applicant discovered that if the stabilizing part is fixedly connected to the lifting end of the lifting mechanism 8 and the base 1, and the pushing mechanism pushes the blade 13, the blade 13 and the stabilizing part will move further and further apart. As the blade 13 is pushed forward, the contact surface between the stabilizing part and the blade 13 will move away from the blade head 14. Therefore, the applicant designated the pushing mechanism as an electric push rod disposed on the surface of the lifting mechanism 8. The electric push rod includes a base 1 and a pushing rod 2. The outer wall of the sleeve 15 is provided with a horizontal and protruding sliding rod. The outer wall of the base 1 is fixedly provided with a sliding box 17 at one end near the sleeve 15, which is slidably connected to the outer wall of the sliding rod of the sleeve 15. A spring 18 is provided between the inner wall of the sliding box 17 near the end of the part 5 and the sliding rod. A connecting rod 16 is fixedly connected between the sleeve 15 and the lifting mechanism 8. The end of the sleeve 15 away from the part 5 is provided with a downwardly extending pushing plate. The base of the long-stroke tool assembly is provided with a pushing rod horizontally disposed corresponding to the position of the pushing plate.
[0044] In practice, the distance between the push rod and the push plate is 2-5cm.
[0045] After the above application, after the pushing mechanism pushes the cutter body 13, the cutter head 14 enters the part 52-5cm, and the push rod on the stabilizing part and the push plate begin to contact. At this time, the push rod pushes the push plate forward, and the sliding rod at the top of the sleeve 15 of the stabilizing part slides in the sliding box 17. At this time, the sleeve 15 also slides towards the cutter head 14, which avoids the stabilizing part on the surface of the cutter body 13 being too far from the cutter head 14. At this time, the stabilizing effect is better, and the cutting of thick-walled parts 5 is more stable. In specific implementation, the distance between the push plate and the push rod can be set according to the thickness of the specific part 5, and the length of the stabilizing part can be set according to the length of the cutter body 13.
[0046] Example 5
[0047] Based on the above embodiments, the cutter head 14 is made of heat-resistant and wear-resistant material.
[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
