Description

Technical Field

[0001] This utility model relates to the field of ultrasonic rolling tool head technology, specifically a cathode roller ultrasonic rolling tool head. Background Technology

[0002] Severe Plastic Deformation (SPD) has the great potential to refine the grain size of coarse-grained materials to the nanometer scale. It is a unique process for preparing ultrafine-grained (nanocrystalline or submicron-crystalline) metals and alloys that has gradually developed in recent years. It refers to a process in which materials undergo intense plastic deformation under high external pressure at relatively low temperatures (typically below 0.4 Tm), thereby refining the grain size to the submicron or nanometer scale. High-strain, large-plastic deformation can significantly refine the microstructure of metallic materials at low temperatures, thereby greatly improving their strength and toughness. In the production of high-performance wire rods, cathode roller ultrasonic rolling tool heads are required.

[0003] Currently, Chinese Patent CN111842530B discloses a high-performance wire manufacturing process and apparatus, belonging to the field of fine grain refinement technology for severe plastic deformation. This process involves steps such as material selection and cleaning, ultrasonic impact strengthening preparation, ultrasonic impact strengthening treatment, two-piece welding, and multi-pass rolling treatment to obtain a finished product with unchanged cross-sectional dimensions. After one ultrasonic impact strengthening treatment, a finished product with uniformly thinned cross-sectional dimensions can be obtained. The low-temperature ultrasonic rolling impact apparatus of this invention includes a sealed container filled with coolant, an ultrasonic transducer, an ultrasonic tool head, a rigid impact roller, an ultrasonic power supply, a rigid roller, a roller drive motor, a pressure cylinder, a spring, and a traction transmission mechanism. The process provided by this invention can achieve efficient and uniform grain refinement of wires or strips with a thickness in the micrometer range, significantly improving the comprehensive mechanical properties of the material. The provided apparatus can achieve low-temperature ultrasonic impact SPD strengthening treatment of wires or strips, satisfying two impact treatment methods.

[0004] However, when the above-mentioned device is used, the rigid impact roller will inevitably be damaged as the usage time increases. Since it is located at the tool head, it is difficult to disassemble and inconvenient for workers.

[0005] Therefore, this utility model provides a cathode roller ultrasonic rolling tool head. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a cathode roller ultrasonic rolling tool head to solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a cathode roller ultrasonic rolling tool head, comprising a tool head body, a rigid impact roller column disposed below the tool head body, a connecting mechanism disposed below the tool head body, and a protective mechanism disposed on the side of the tool head body;

[0008] The connecting mechanism includes a connecting frame, which is rotatably connected to the rigid impact roller through a bearing. A connecting groove is provided at the bottom of the tool head body, and the inner wall of the connecting groove is in sliding fit with the connecting frame. The connecting frame can be installed in the connecting groove through a positioning component.

[0009] Preferably, the positioning component includes a positioning block, and positioning grooves are provided on both outer walls of the connecting frame, and moving grooves are provided on both inner walls of the connecting grooves. The inner walls of the positioning grooves and the moving grooves are in sliding fit with the positioning block.

[0010] Preferably, both outer walls of the tool head body are provided with movable openings extending into the movable groove, and the inner wall of the movable opening is slidably connected with a movable rod, which is fixed to the positioning block.

[0011] Preferably, a plurality of movable springs are fixedly connected to one side of the positioning block, and the movable springs are fixed to the inner wall of one side of the movable groove.

[0012] Preferably, the protective mechanism includes two protective plates, and protective grooves are provided on both outer walls of the tool head body. The protective plates are close to the protective grooves, and the moving rod is located inside the protective plates.

[0013] Preferably, the outer walls on both sides of the protective groove are provided with rotating grooves, and the inner wall of the rotating groove is rotatably connected to a rotating shaft through a bearing. The surface of the rotating shaft is fixed to the protective plate.

[0014] Preferably, a torsion spring is wrapped around the surface end of the rotating shaft, and the torsion spring is fixed to both the protective plate and the inner wall of the rotating groove.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] (1) The cathode roller ultrasonic rolling tool head can be separated from the inner wall of the positioning groove by the movement of the positioning block. At this time, the moving spring is compressed, which can separate the connecting frame from the connecting groove. When installing it, the above operation can be reversed. Therefore, the roller can be disassembled to facilitate the operation of the staff.

[0018] (2) The cathode roller ultrasonic rolling tool head can make the rotating shaft rotate in the rotating groove by the elastic force of the torsion spring, so that the protective plate covers the moving rod, which can prevent the moving rod from moving outward due to accidental collision, and can make the rigid impact roller column installed stably.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A cathode roller ultrasonic rolling tool head includes a tool head body 1, a rigid impact roller 2 disposed below the tool head body 1, a connecting mechanism disposed below the tool head body 1, and a protective mechanism disposed on the side of the tool head body 1.

[0026] The connecting mechanism includes a connecting frame 3, which is rotatably connected to the rigid impact roller 2 via bearings. A connecting groove 4 is provided at the bottom of the tool head body 1. The inner wall of the connecting groove 4 is in sliding fit with the connecting frame 3. The connecting frame 3 can be installed in the connecting groove 4 by means of a positioning element, which includes a positioning block 5. Positioning grooves 6 are provided on both outer walls of the connecting frame 3, and moving grooves 7 are provided on both inner walls of the connecting groove 4. The inner walls of the positioning grooves 6 and the moving grooves 7 are in sliding fit with the positioning block 5.

[0027] Specifically, the positioning block 5 can be separated from the inner wall of the positioning groove 6 by moving. At this time, the moving spring 10 is compressed, which can separate the connecting frame 3 from the connecting groove 4. When installing it, the above operation can be reversed. Therefore, the roller can be disassembled, which makes it easier for the staff to operate.

[0028] As a further improvement of this utility model, the outer walls on both sides of the tool head body 1 are provided with moving openings 8 that extend into the moving groove 7. The inner wall of the moving opening 8 is slidably connected with a moving rod 9, and the moving rod 9 is fixed to the positioning block 5.

[0029] Specifically, by sliding the movable rod 9 within the inner wall of the movable opening 8, the positioning block 5 can move within the inner wall of the movable groove 7, and the movement of the positioning block 5 can separate it from the inner wall of the positioning groove 6.

[0030] As a further improvement of this utility model, a number of movable springs 10 are fixedly connected to one side of the positioning block 5, and the movable springs 10 are fixed to the inner wall of one side of the movable groove 7.

[0031] Specifically, after the positioning groove 6 is aligned with the moving groove 7, the positioning block 5 can slide into the positioning groove 6 through the inner wall of the moving groove 7 under the elastic force of the moving spring 10.

[0032] As a further improvement of this utility model, the protective mechanism includes two protective plates 11. Protective grooves 12 are provided on both outer walls of the tool head body 1. The protective plates 11 are close to the protective grooves 12, and the moving rod 9 is located inside the protective plates 11.

[0033] Specifically, by covering the moving rod 9 with the protective plate 11, the moving rod 9 can be prevented from moving outward due to accidental contact, thus ensuring the stable installation of the rigid impact roller 2.

[0034] As a further improvement of this utility model, rotating grooves 13 are provided on both outer walls of the protective groove 12. A rotating shaft 14 is rotatably connected to the inner wall of the rotating groove 13 through a bearing. The surface of the rotating shaft 14 is fixed to the protective plate 11. A torsion spring 15 is wrapped around the end of the surface of the rotating shaft 14. The torsion spring 15 is fixed to both the protective plate 11 and the inner wall of the rotating groove 13.

[0035] Specifically, the spring force of the torsion spring 15 allows the rotating shaft 14 to rotate within the rotating groove 13, which allows the protective plate 11 to cover the moving rod 9.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] The working principle of this utility model is as follows: When in use, the protective mechanism is opened, exposing the connecting mechanism. At this time, the moving rod 9 can be pulled, and the moving rod 9 slides in the inner wall of the moving port 8, allowing the positioning block 5 to move in the inner wall of the moving groove 7. The movement of the positioning block 5 can separate it from the inner wall of the positioning groove 6. At this time, the moving spring 10 is compressed, which can separate the connecting frame 3 from the connecting groove 4. During the installation operation, the positioning block 5 can be placed in the moving groove 7. The connecting frame 3 is inserted into the connecting groove 4. After the positioning groove 6 and the moving groove 7 are aligned, the positioning block 5 can slide through the inner wall of the moving groove 7 into the positioning groove 6 under the elastic force of the moving spring 10. Therefore, the roller can be disassembled, achieving the effect of facilitating operation by the staff.

[0038] After the rigid impact roller 2 is installed, the spring force of the torsion spring 15 allows the rotating shaft 14 to rotate in the rotating groove 13, which allows the protective plate 11 to cover the moving rod 9, preventing the moving rod 9 from moving outward due to accidental contact, and making the rigid impact roller 2 installed stably.
