Description

Technical Field

[0001] The present application belongs to the technical field of bending mechanisms, and specifically relates to a metal wire bending mechanism. Background Art

[0002] Metal wire electric explosion refers to inserting a metal wire between the high-voltage electrode and the low-voltage electrode of the energy converter of the shock wave generator. The energy converter discharges through the short circuit of the metal wire and injects a pulse current of a certain parameter into the metal wire. Under the action of Joule heating, the metal wire undergoes a rapid phase change, successively experiencing solid, liquid, gas and plasma states, and finally develops into a plasma channel. Under the action of the subsequent discharge current, the plasma arc resistor heats the surrounding water medium by the Joule heating principle to make it vaporize and expand rapidly, accompanied by physical phenomena such as light radiation and shock waves. The shock wave generated by the energy converter manufactured by the principle of metal wire electric explosion acts on targets such as coal seams, rock formations, and stones, which can cause the coal seams and rock formations to fracture, or break the stones. The shock wave generated by the energy converter is highly controllable and has a good fracturing effect, so it is expected to replace traditional fracturing methods such as hydraulic fracturing and gunpowder fracturing. According to experiments, the bent S-shaped metal wire can generate a shock wave with greater energy after electric explosion, so the cracking effect is good. However, there is currently no metal wire bending mechanism suitable for metal wire electric explosion, which makes it difficult to meet current usage needs. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the embodiments of the present utility model, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the present utility model. The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0033] like Figures 1 to 7 As shown, the metal wire bending mechanism provided by the embodiment of the utility model includes a first wire folding wheel 1, a second wire folding wheel 2, a first transmission assembly 3, a second transmission assembly 4 and a driving motor 5.

[0034] The output shaft of the driving motor 5 is connected to the rotating shaft of the first folding wheel 1 through the first transmission assembly 3, and the output shaft of the driving motor 5 is connected to the rotating shaft of the second folding wheel 2 through the second transmission assembly 4. The first folding wheel 1 and the second folding wheel 2 rotate in opposite directions.

[0035] The first wire folding wheel 1 and the second wire folding wheel 2 have the same structure, and both the first wire folding wheel 1 and the second wire folding wheel 2 include a wheel body 6 and a plurality of shifting teeth 7. The plurality of shifting teeth 7 are evenly distributed in the circumference of the wheel body 6.

[0036] The first wire folding wheel 1 and the second wire folding wheel 2 are arranged side by side, the adjacent teeth 7 of the first wire folding wheel 1 and the teeth 7 of the second wire folding wheel 2 are arranged crosswise, and the metal wire 8 passes through the S-shaped space between the teeth 7 of the first wire folding wheel 1 and the teeth 7 of the second wire folding wheel 2.

[0037] It should be noted that when the mechanism is working, the driving motor 5 drives the first wire folding wheel 1 and the second wire folding wheel 2 to rotate in opposite directions through the first transmission component 3 and the second transmission component 4, and then the end of the metal wire 8 is extended into the S-shaped space. When the first wire folding wheel 1 and the second wire folding wheel 2 rotate, the teeth 7 of the first wire folding wheel 1 and the teeth 7 of the second wire folding wheel 2 apply friction to the metal wire 8 to form a traction force on the metal wire 8, so that the metal wire 8 passes through the S-shaped space. In this process, the metal wire 8 forms an S-shaped structure under the action of the teeth 7 of the first wire folding wheel 1 and the teeth 7 of the second wire folding wheel 2. The utility model sets the first wire folding wheel 1 and the second wire folding wheel 2 with opposite rotation directions, and can bend the metal wire 8 into an S-shaped structure while pulling the metal wire 8, thereby meeting the use requirements of the electric explosion of the metal wire 8. The mechanism only needs one set of driving components, so the structure is simple, and the mechanism can form an S-shaped structure of a set shape, so it is highly practical and easy to promote and use.

[0038] In this embodiment, a wire folding groove 71 is provided at the center of the end of the shifting tooth 7 , and the metal wire 8 is clamped in the wire folding groove 71 .

[0039] It should be noted that the metal wire 8 is clamped in the wire folding groove 71 during the bending process, and the wire folding groove 71 can enable the metal wire 8 to move in a set direction and form a uniform S-shaped structure.

[0040] In this embodiment, the teeth 7 of the first wire folding wheel 1 and the teeth 7 of the second wire folding wheel 2 located on both sides of the metal wire 8 partially overlap in the horizontal direction, the teeth 7 of the first wire folding wheel 1 and the second wire folding wheel 2 are arranged at intervals, and the teeth 7 of the second wire folding wheel 2 and the first wire folding wheel 1 are arranged at intervals.

[0041] It should be noted that the shifting teeth 7 at different positions can form metal wires 8 of S-shaped structures in different shapes.

[0042] In this embodiment, the number of the shifting teeth 7 is 7 to 9.

[0043] It should be noted that 7 to 9 shift teeth 7 can form an optimal S-shaped structure, avoiding the problem that a small number of shift teeth 7 makes it difficult to form an S-shaped structure or a large number of shift teeth leads to excessive resistance of the metal wire 8 .

[0044] In this embodiment, the end of the shifting tooth 7 of the first folding wheel 1 is close to the outer wall of the wheel body 6 of the second folding wheel 2 , and the end of the shifting tooth 7 of the second folding wheel 2 is close to the outer wall of the wheel body 6 of the first folding wheel 1 .

[0045] It should be noted that the shifting teeth 7 are close to the outer wall of the wheel body 6, which can ensure that the metal wire 8 passes through the S-shaped structure and at the same time form a set traction force to send out the bent metal wire 8.

[0046] In the first embodiment, the first transmission assembly 3 and the second transmission assembly 4 have the same structure, and the first transmission assembly 3 and the second transmission assembly 4 are centrally symmetrical.

[0047] The first transmission assembly 3 and the second transmission assembly 4 each include a driving bevel gear 12 , a driven bevel gear 13 , a driven gear shaft 14 , a pinion gear 15 , a large gear 16 and an output gear shaft 17 .

[0048] One end of the driven gear shaft 14 is rotatably mounted, and the other end of the driven gear shaft 14 is mounted with a driven bevel gear 13. A pinion 15 is mounted in the middle of the driven gear shaft 14.

[0049] The output gear shaft 17 is rotatably installed, and a large gear 16 and a first folding wheel 1 or a second folding wheel 2 are installed on the output gear shaft 17. The large gear 16 is located on one side of the output gear shaft 17, and the large gear 16 is meshed with a small gear 15. The first folding wheel 1 or the second folding wheel 2 is located in the middle of the output gear shaft 17. The end of the output shaft of the driving motor 5 is installed with a driving bevel gear 12, and the driving bevel gear 12 is meshed with the driven bevel gear 13 of the first transmission assembly 3 and the driven bevel gear 13 of the second transmission assembly 4.

[0050] It should be noted that the driving motor 5 drives the active bevel gear 12 to rotate, the active bevel gear 12 drives the driven bevel gear 13 to rotate, the driven bevel gear 13 drives the driven gear shaft 14 to rotate, the driven gear shaft 14 drives the pinion 15 to rotate, the pinion 15 drives the large gear 16 to rotate, the large gear 16 drives the output gear shaft 17 to rotate, and the output gear drives the first folding wheel 1 or the second folding wheel 2 to rotate. Since the first transmission assembly 3 and the second transmission assembly 4 are centrally symmetrical, that is, the driven bevel gear 13 of the first transmission assembly 3 and the driven bevel gear 13 of the second transmission assembly 4 are respectively located on both sides of the active bevel gear 12, the driven bevel gear 13 of the first transmission assembly 3 and the driven bevel gear 13 of the second transmission assembly 4 rotate in opposite directions, thereby causing the first folding wheel 1 and the second folding wheel 2 to rotate in opposite directions.

[0051] In this embodiment, a wire feeding hole 18 is provided at the center of the output shaft of the driving motor 5 and the center of the active bevel gear 12 , and the metal wire 8 passes through the wire feeding hole 18 .

[0052] It should be noted that, by providing the wire feeding hole 18 , the drive motor 5 , the first transmission assembly 3 and the second transmission assembly 4 can be arranged side by side according to the conveying direction of the metal wire 8 , thereby meeting the installation requirements of the shock wave generator.

[0053] like Figure 7 As shown, in the second embodiment, the first transmission assembly 3 includes a driven gear shaft 14 and a driven gear 9 , and the driven gear 9 and the first folding wheel 1 are mounted on the driven gear shaft 14 .

[0054] The second transmission assembly 4 comprises a driving gear shaft 10 and a driving gear 11 , and the driving gear 11 and the second folding wheel 2 are mounted on the driving gear shaft 10 .

[0055] The driven gear 9 is meshed with the driving gear 11 , and the driving gear shaft 10 is connected to the output shaft of the driving motor 5 .

[0056] It should be noted that the driving motor 5 drives the driving gear 11 to rotate forward through the driving gear shaft 10, thereby causing the second folding wheel 2 to rotate forward, and the driven gear 9 and the driving gear 11 are meshed, causing the driven gear 9 to rotate reversely, thereby causing the driven gear shaft 14 to rotate reversely, causing the first folding wheel 1 to rotate reversely, and finally causing the first folding wheel 1 and the second folding wheel 2 to rotate in opposite directions.

[0057] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
