Specialized chopping knife for titanium forging

Abstract

This utility model discloses a special chopping knife for titanium forging parts, relating to the field of forging equipment technology. The utility model includes a base, with the chopping knife body disposed inside the base; an anti-detachment mechanism is provided on one side of the base, comprising a fixed box fixedly connected to one side of the base, and a fixed cylinder disposed inside the fixed box. This utility model, through the synergistic effect of the worm gear transmission and the mechanical interlocking of the locking rod and locking hole in the anti-detachment mechanism, effectively prevents the mounting bolts from loosening due to vibration. The self-locking characteristic of the worm gear ensures that the locking rod will not rotate on its own due to reverse load after locking, while the structure of the locking rod inserting into the locking hole of the limiting disc forms a physical limit, providing double protection for installation stability and avoiding safety accidents caused by the chopping knife falling off. The transmission design of the first bevel gear and the second bevel gear in the drive mechanism converts the rotational motion input from the handle into the axial drive of the worm gear.

Description

Technical Field

[0001] This utility model belongs to the technical field of forging and pressing equipment, and in particular relates to a special chopping knife for titanium forging parts. Background Technology

[0002] Titanium alloys are widely used in aerospace and high-end equipment manufacturing due to their high strength, corrosion resistance, and lightweight properties. During the forging process of titanium alloys, a cutting tool is often used for material cutting and separation. In existing technologies, the cutting tool is mostly directly bolted to the equipment base. However, under the high-intensity, high-frequency forging vibration environment, the bolt is prone to loosening or even falling off, posing a safety hazard and also affecting processing accuracy and efficiency.

[0003] Traditional anti-loosening measures, such as adding spring washers or using double nuts, have limited effectiveness under strong impact and vibration conditions, and the disassembly and assembly process is cumbersome, failing to meet the dual requirements of efficiency and safety in titanium alloy forging production. Therefore, we provide a special chopping knife for titanium forging parts to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a special chopping knife for titanium forging parts. Through the cooperation of the anti-loosening mechanism and the driving mechanism, it solves the problems of easy loosening and inconvenient disassembly and assembly in the existing special chopping knife for titanium forging parts in the vibrating environment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a special chopping knife for titanium forging parts, comprising a base, with the chopping knife body disposed inside the base; an anti-detachment mechanism is disposed on one side of the base, the anti-detachment mechanism comprising a fixed box fixedly connected to one side of the base, a fixed cylinder disposed inside the fixed box, a sliding hole opened on the surface of the fixed cylinder, and a locking rod slidably connected to the inside of the sliding hole; a driving mechanism is also disposed on one side of the base, the driving mechanism comprising a housing fixedly connected to one side of the base, and a rotating shaft rotatably connected to the inner cavity of the housing through a bearing seat.

[0007] The present invention is further provided that a bolt hole is provided on one side of the base, and a mounting bolt is threaded into the inner side of the bolt hole.

[0008] The present invention is further configured such that a limiting plate is fixedly connected to the surface of the mounting bolt, and the surface of the limiting plate is provided with a locking hole. When the locking rod is inserted into the locking hole, the mounting bolt can be prevented from loosening, thus ensuring working stability.

[0009] The present invention is further configured such that a worm gear ring is provided inside the fixed box, a worm is engaged on the surface of the worm gear ring, a support rod is movably connected to the inner side of the worm gear ring, the other end of the support rod is movably connected to one end of the clamping rod, and a plurality of circumferentially distributed support rods are hinged to the inner side of the worm gear ring, the other end of the support rod is movably connected to one end of the clamping rod, and the worm gear ring is driven to rotate by the worm, which drives the support rod to push the clamping rod to move linearly along the sliding hole.

[0010] The present invention is further configured such that a guide post is fixedly connected to one side of the worm gear ring, and a circular groove adapted to the guide post is opened in the inner cavity of the fixed box. Through the gap fit between the circular groove and the guide post, only the circumferential rotation of the worm gear ring is restricted, thereby converting the rotational motion of the worm gear ring into the vertical linear motion of the lever.

[0011] The present invention is further configured such that a first bevel gear is fixedly connected to the surface of the rotating shaft, a second bevel gear meshes with the surface of the first bevel gear, and the shaft center of the second bevel gear is fixedly connected to the surface of the worm. The direction of power is changed through bevel gear transmission, and the rotational motion is transmitted to the worm.

[0012] The present invention is further configured such that the other end of the rotating shaft passes through the chassis and is fixedly connected to a handle. The surface of the handle is provided with anti-slip texture, which makes it convenient for the operator to apply force. At the same time, it can be rotated quickly and the position of the lever can be precisely controlled. Meanwhile, rotating the handle can drive the entire transmission system to operate, realizing one-handed operation.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model, through the synergistic effect of the worm gear transmission and the mechanical interlocking of the locking rod and locking hole in the anti-detachment mechanism, can effectively prevent the installation bolts from loosening due to vibration. The self-locking characteristic of the worm gear (the worm lead angle is less than the friction angle) ensures that the locking rod will not rotate on its own due to reverse load after locking. The structure of the locking rod inserting into the locking hole of the limiting plate forms a physical limit, providing double protection for installation stability and avoiding safety accidents caused by the detachment of the chopping knife. The transmission design of the first bevel gear and the second bevel gear in the drive mechanism can convert the rotational motion input by the handle into the axial drive of the worm, allowing the operator to complete the extension and retraction of the locking rod by rotating the handle with one hand, which is convenient and labor-saving.

[0015] 2. The fixed cylinder of this utility model has a sliding connection design between the sliding hole and the clamping rod, which ensures that the clamping rod can only move in a straight line in the vertical direction to avoid uneven wear. The worm gear ring restricts the circumferential degree of freedom through the cooperation of the guide post and the circular groove to ensure transmission accuracy.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model is a special chopping knife for titanium forging parts, including a base 1, a chopping knife body 2 is provided inside the base 1; an anti-detachment mechanism is provided on one side of the base 1, the anti-detachment mechanism includes a fixed box 3 fixedly connected to one side of the base 1, a fixed cylinder 4 provided inside the fixed box 3, a sliding hole 5 opened on the surface of the fixed cylinder 4, and a locking rod 6 slidably connected to the inside of the sliding hole 5; a driving mechanism is also provided on one side of the base 1, the driving mechanism includes a housing 7 fixedly connected to one side of the base 1, and a rotating shaft 8 rotatably connected to the inner cavity of the housing 7 through a bearing seat.

[0027] Further details: The locking rod 6 can move vertically up and down along the fixed cylinder 4. The outer wall of the worm gear ring 13 is in clearance fit with the inner wall of the fixed box 3. Through the circular groove, it is in clearance fit with the guide post 16, which only restricts the circumferential rotation of the worm gear ring 13. Thus, the rotational motion of the worm gear ring 13 is converted into the vertical linear motion of the locking rod 6. Through the combination of worm gear 14 transmission and linkage mechanism, the fast locking and anti-loosening of the chopper mounting bolt 10 is realized, which improves the safety of operation.

[0028] Example 2

[0029] Please see Figures 1-5 Based on embodiment 1, a bolt hole 9 is provided on one side of the base 1, and a mounting bolt 10 is threadedly connected to the inside of the bolt hole 9. A limiting plate 11 is fixedly connected to the surface of the mounting bolt 10. A locking hole 12 is provided on the surface of the limiting plate 11. A worm gear ring 13 is provided inside the fixed box 3. A worm 14 is meshed on the surface of the worm gear ring 13. A support rod 15 is movably connected to the inside of the worm gear ring 13. The other end of the support rod 15 is movably connected to one end of the locking rod 6. A guide post 16 is fixedly connected to one side of the worm gear ring 13. A circular groove adapted to the guide post 16 is opened in the inner cavity of the fixed box 3. A first bevel gear 17 is fixedly connected to the surface of the rotating shaft 8. A second bevel gear 18 is meshed on the surface of the first bevel gear 17. The other end of the rotating shaft 8 passes through the housing 7 and is fixedly connected to a handle 19.

[0030] Further details: When the locking rod 6 is inserted into the locking hole 12, it prevents the mounting bolt 10 from loosening, ensuring operational stability. Multiple circumferentially distributed support rods 15 are hinged to the inner side of the worm gear ring 13. The other end of each support rod 15 is movably connected to one end of the locking rod 6. The worm gear ring 13 is driven to rotate via the worm 14, causing the support rods 15 to push the locking rod 6 along the sliding hole 5 in a straight line. The second bevel gear 18 is fixedly connected to the surface of the worm 14 at its shaft center. The direction of power is changed through bevel gear transmission, transmitting the rotational motion to the worm 14. The handle 19 has anti-slip textures on its surface, facilitating force application by the operator. It also allows for rapid rotation and precise control of the locking rod 6's position. Furthermore, rotating the handle 19 drives the entire transmission system, enabling one-handed operation.

[0031] The working principle of this utility model is as follows: When it is necessary to fix the chopper body 2, first tighten the mounting bolt 10, then rotate the handle 19 clockwise. This drives the first bevel gear 17 to rotate via the rotating shaft 8, which in turn drives the second bevel gear 18 and the worm gear 14 to rotate. The worm gear 14 drives the worm wheel ring 13 to rotate, which pushes the three locking rods 6 outward along the sliding hole 5 via the support rod 15. These rods then insert into the locking holes 12 of the limiting plate 11, forming a mechanical interlock. Due to the self-locking characteristics of the worm wheel and worm gear 14, they will not loosen even under vibration, ensuring operational safety. When disassembly is required, rotating the handle 19 counterclockwise will retract the locking rods 6.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
