Description

Technical Field

[0001] The invention relates to the technical field of wire twisting machines, and in particular to a fork-type wire twisting machine for cable processing. Background Art

[0002] When processing cables, a fork-type twisting machine is required to rotate and twist multiple strands of soft and hard conductor wires into strands, such as copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.; when the fork-type twisting machine is working, multiple strands of conductor wires are released from the pay-off reel, and pass through multiple twisting holes opened on the capstan, pass through the twisting holes and converge to form a line, then the capstan starts to rotate, and the gathered twisted wires are continuously pulled out, and cooperate with the rotation of the capstan to make the multiple strands of conductor wires twisted into a wire in the form of spiral winding; but in the prior art, the twisting holes on the capstan and the conductor wires passing at high speed will continuously contact at one position and cause wear. Although wear-resistant parts are installed at the twisting holes to deal with this problem, the life of the wear-resistant parts will inevitably be reduced after such continuous consumption, and optimization and improvement are urgently needed. Summary of the invention

The number of the wire tube and the No. 3 gear are both eight groups, and are distributed at equal angles inside the wire winding disk. The No. 3 gear at the top is meshed with the No. 2 gear, and the eight adjacent groups of the No. 3 gears are meshed with each other.

[0008] As a preferred solution of the present invention, the bracket is fixedly installed at a position slightly to the left of the middle of the top surface of the workbench, the motor is located on the right side of the bracket, and is connected to the wire twisting disc through a belt, the belt is movably sleeved on the outer surface of the wire twisting disc, and the collecting cylinder is fixedly installed in the middle of the support and is provided with a left-facing bell-mouth structure;

[0009] The two groups of No. 2 ventilation grooves are respectively located on the left and right sides of the belt, and the number of the No. 2 ventilation grooves in each group is sixteen, and they are distributed at equal angles on the outer surface of the wire twisting drum.

[0010] As a preferred solution of the present invention, the fixer is formed by integrally welding an intermediate shaft and two discs located at both ends thereof, wherein the discs are rotatably mounted with the wire winding discs via bearings, and the outer surface of the intermediate shaft is fixedly connected to the No. 1 gear.

[0011] As a preferred solution of the present invention, the diameters of the No. 1 gear and the No. 2 gear are equal, the diameter of the No. 2 gear is smaller than the diameter of the No. 3 gear, and four groups of reinforcement blocks with equal angles are fixedly installed on the outer surface of the fixed column close to the bracket. The left side of the reinforcement block is fixedly connected to the bracket, and the shape of the reinforcement block is a triangle.

[0012] As a preferred solution of the present invention, the number of air guide plates in each group is two, and they are centrally symmetrical around the axis of the wire tube. The air guide plates are tilted around the radial line of the wire tube. The two groups of air guide plates located on the left and right sides of the No. 3 gear are tilted oppositely, and the air guide plates installed on the outer surfaces of adjacent rotating shafts are tilted oppositely.

[0013] As a preferred solution of the present invention, the wire barrel is made of chromium carbide wear-resistant steel, and a circular protrusion structure is provided at the end of the wire barrel opposite to the transport direction of the conductor wire, the circular protrusion structure abuts against one end of the rotating shaft, and the wire barrel is arranged on the inner wall of the rotating shaft in an interference fit.

[0014] As a preferred solution of the present invention, the side of the outer surface of the conductor wire facing the axis of the wire winding drum is in frictional contact with the inner wall of the wire barrel, and the right side of the inner wall of the wire barrel is designed in an arc transition.

[0015] The working principle and beneficial effects of the present invention are:

[0016] The present invention redesigns the interior of the wire winding drum to achieve a uniform surface wear function for the wire drum, that is, the wire wear caused by the single contact friction between the conductor wire and the wire drum is transformed into a surface wear function after the wire drum rotates, thereby greatly reducing the wear degree of the wire drum and extending its service life. By arranging eight sets of rotating shafts, a third gear and a wire drum on the inner wall of the wire winding drum, the wire drum and the third gear can realize coaxial rotation. When the wire winding drum is driven by the motor to rotate, the third gear and the second gear are driven to revolve. At this time, since the first gear is fixed, the second gear generates a rotating power, which is then transmitted to the third gear meshing with the second gear. Then, the third gear transmits the power to the remaining seven sets of third gears in sequence. The wire drum is driven by the third gear and the rotating shaft to rotate synchronously around its own axis at a relatively low speed, so that the contact point between the conductor wire and its inner wall is always changing, thereby realizing the surface wear function, reducing the wear degree of a single position of the inner wall of the wire drum and extending the service life of the wire winding drum.

[0017] 2. At the same time, by opening a No. 2 ventilation groove and a No. 1 ventilation groove on the outer surface of the wire twisting disk and on both sides thereof, an air circulation channel inside and outside the wire twisting disk is formed. When the wire twisting disk rotates, the rotational power generated by the No. 1 gear, the No. 2 gear and the No. 3 gear is used to drive the air guide plate to rotate, so that the outside air is sucked into the wire twisting disk along the No. 2 ventilation groove and discharged from the No. 1 ventilation groove, forming a complete air circulation system. By opening a card slot on the outer surface of the rotating shaft and plugging in a heat conduction plate, the heat generated by the wear of the wire barrel is absorbed, and the heat is synchronously taken away through the air circulation system, thereby realizing the synchronous heat dissipation function of the wire twisting machine.

[0018] 3. In the wire winding disk, gear No. 1, gear No. 2 and eight groups of gear No. 3 distributed around the axis of gear No. 1 form a "quasi-planetary gear set" structure, which lacks a gear ring. The function is to fix gear No. 1 with a fixer, and use the wire winding disk to rotate and drive gear No. 2 and gear No. 3 to generate orbital power around the axis of the wire winding disk. Since gear No. 2 is set to always mesh with the outer surface of gear No. 1, when it rotates around gear No. 1, it will convert the orbital power into its own rotational power, and then transmit the power to gear No. 3. While realizing the function of synchronous rotation of the wire barrel to reduce wear, the difference in diameter between gear No. 2 and gear No. 3 is used to reduce the rotation speed of gear No. 3 and the wire barrel, so that the change speed of the contact position between the wire barrel and the conductor line is reduced, avoiding another kind of "excessive surface wear" of the inner wall of the wire barrel.

DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-8As shown, a fork-type wire twisting machine for cable processing comprises a workbench (1), a bracket (2), a motor (5), a support (6) and a collecting drum (7), wherein a plurality of groups of wire tubes (3) are fixedly mounted on the left side of the bracket (2), and the wire tubes (3) are used for conductors (4) to pass through, and a fixing column (8) and a fixing device (10) are fixedly mounted on the right side of the bracket (2), and a first gear (11) is fixedly mounted on the outer surface of the fixing device (10), and a wire twisting disc (12) is rotatably mounted via a bearing;

[0031] The inner wall of the wire twisting disc (12) is rotatably mounted with a second gear (15) and a rotating shaft (16) through bearings, and a third gear (17) is fixedly mounted on the outer surface of the rotating shaft (16). The second gear (15) is meshed with the first gear (11) and the third gear (17) respectively. A wire tube (18) is movably inserted inside the rotating shaft (16). The conductor wires (4) are arranged in eight groups and are distributed at equal angles and pass through the wire tube (3), the bracket (2), and the wire tube (18) in sequence to the right, and finally collected in the collecting tube (7). The number of the wire tube (18) and the third gear (17) is eight groups, and they are distributed at equal angles inside the wire twisting disc (12). The third gear (17) located at the top is meshed with the second gear (15), and the eight groups of the third gear (17) are meshed with each other.

[0032] The present invention redesigns the interior of the wire twisting disc (12) to achieve a uniform surface wear function for the wire barrel (18), that is, the wire wear caused by the original single contact friction between the conductor wire (4) and the wire barrel (18) is transformed into a surface wear function after the wire barrel (18) rotates, thereby greatly reducing the degree of wear of the wire barrel (18) and extending its service life. By arranging eight sets of rotating shafts (16), a third gear (17) and the wire barrel (18) on the inner wall of the wire twisting disc (12), the wire barrel (18) and the third gear (17) can rotate coaxially. When the wire twisting disc (12) is driven by a motor (5) to rotate, the third gear (17) and the second gear (18) are rotated. (15) is driven to revolve. At this time, since the No. 1 gear (11) is fixed, the No. 2 gear (15) generates a rotational force, which is then transmitted to the No. 3 gear (17) meshing with the No. 2 gear (15). Then, the No. 3 gear (17) transmits the power to the remaining seven groups of No. 3 gears (17) in sequence. The wire barrel (18) is driven by the No. 3 gear (17) and the rotating shaft (16) to rotate synchronously around its own axis at a relatively low speed, so that the contact point between the conductor wire (4) and its inner wall is always changing, thereby realizing the surface wear function, reducing the wear degree of a single position of the inner wall of the wire barrel (18), and extending the service life of the wire reel (12).

[0033] The outer surface of the twisting disc (12) is provided with two groups of No. 2 ventilation grooves (14), the left and right sides of the twisting disc (12) are provided with No. 1 ventilation grooves (13), the outer surface of the rotating shaft (16) is fixedly provided with two groups of air guide plates (19) distributed on the left and right sides of the No. 3 gear (17), the left and right sides of the outer surface of the rotating shaft (16) are provided with card slots (20), the inside of the card slots (20) is movably plugged with a heat conducting plate (21) fixedly connected to the outer surface of the wire tube (18), and the heat conducting plate (21) is made of brass;

[0034] By respectively providing a second ventilation groove (14) and a first ventilation groove (13) on the outer surface of the twisting disc (12) and on both sides thereof, an air circulation channel inside and outside the twisting disc (12) is formed. When the twisting disc (12) rotates, the rotational power generated by the first gear (11), the second gear (15) and the third gear (17) is used to drive the air guide plate (19) to rotate, so that the outside air is sucked into the inside of the twisting disc (12) along the second ventilation groove (14) and discharged from the first ventilation groove (13), forming a complete air circulation system. By providing a card slot (20) on the outer surface of the rotating shaft (16) and inserting a heat conducting plate (21), the heat generated by the wire tube (18) due to wear is absorbed and the heat is synchronously taken away through the air circulation system, thereby realizing the synchronous heat dissipation function of the twisting machine.

[0035] The bracket (2) is fixedly mounted on the left side of the middle of the top surface of the workbench (1); the motor (5) is located on the right side of the bracket (2) and is connected to the wire twisting disc (12) through a belt, and the belt is movably sleeved on the outer surface of the wire twisting disc (12); the collecting barrel (7) is fixedly mounted on the middle of the support (6) and is provided with a left-facing bell-mouth structure;

[0036] The two groups of No. 2 ventilation grooves (14) are respectively located on the left and right sides of the belt, and the number of each group of No. 2 ventilation grooves (14) is sixteen and is evenly distributed on the outer surface of the twisting disk (12); the No. 2 ventilation grooves (14) are distributed on both sides of the belt, corresponding to the heat dissipation of the left and right groups of heat conducting plates (21);

[0037] A wire-protecting wheel is arranged on the left side of the bracket (2), and the number of the wheels is equal to the number of the conductor wires (4). A wire-collecting wheel is arranged on the right side of the support (6), which is responsible for collecting the twisted cables. Since the above two structures are both prior arts and do not fall within the scope of protection of the present invention, they can be reasonably omitted here. The bell-shaped design on the left side of the collecting tube (7) can limit the position of the eight groups of conductor wires (4) and collect them together.

[0038] The fixer (10) is formed by integrally welding an intermediate shaft and two discs at both ends thereof, wherein the discs are rotatably mounted on the wire twisting disc (12) via bearings, and the outer surface of the intermediate shaft is fixedly connected to the first gear (11);

[0039] The holder (10) is fixed as a whole and provides rotation support for the wire winding disc (12). When the wire winding disc (12) rotates, it drives the second gear (15) inside it to revolve around the axis of the first gear (11), and forces the second gear (15) to rotate, thereby transmitting the power of the wire winding disc (12) to the second gear (15) and the third gear (17). This design cleverly utilizes the rotation power of the wire winding disc (12) to realize the synchronous rotation of the wire guide tube (18), greatly reducing the wear of the wire guide tube (18). In addition, the first gear (11), the second gear (15) and the third gear (17) are gear meshing transmissions, which greatly improves the stability of the synchronous feeding of the wire winding.

[0040] The diameters of the first gear (11) and the second gear (15) are equal, the diameter of the second gear (15) is smaller than the diameter of the third gear (17), four groups of reinforcing blocks (9) with equal angles are fixedly mounted on the outer surface of the fixing column (8) close to the bracket (2), the left side of the reinforcing block (9) is fixedly connected to the bracket (2), and the shape of the reinforcing block (9) is triangular;

[0041] like Figure 5 As shown, in the wire winding disk (12), the first gear (11), the second gear (15) and eight groups of third gears (17) distributed around the axis of the first gear (11) form a "quasi-planetary gear set" structure, in which there is no ring gear; the function is to fix the first gear (11) with the fixer (10), and use the wire winding disk (12) to rotate and drive the second gear (15) and the third gear (17) to generate a revolving force around the axis of the wire winding disk (12). Since the second gear (15) is arranged to be parallel to the outer surface of the first gear (11), the second gear (15) and the third gear (17) are rotated to generate a revolving force around the axis of the wire winding disk (12). The surfaces are always meshed, and when it rotates around the first gear (11), it converts the revolution power into its own rotation power, and then transmits the power to the third gear (17). While realizing the function of synchronous rotation of the wire barrel (18) to reduce wear, the difference in diameter between the second gear (15) and the third gear (17) is used to reduce the rotation speed of the third gear (17) and the wire barrel (18), so that the contact position change speed between the wire barrel (18) and the conductor wire (4) is reduced, thereby avoiding another "excessive surface wear" of the inner wall of the wire barrel (18);

[0042] Excessive surface wear: When the wire barrel (18) rotates too fast, the dynamic mutual wear between its inner wall and the outer surface of the conductor wire (4) will be aggravated.

[0043] The number of each group of air guide plates (19) is two, and they are centrally symmetrical around the axis of the wire tube (18). The air guide plates (19) are arranged obliquely around the radial line of the wire tube (18). The two groups of air guide plates (19) located on the left and right sides of the third gear (17) are arranged in opposite inclinations, and the air guide plates (19) installed on the outer surfaces of the adjacent rotating shafts (16) are arranged in opposite inclinations.

[0044] The inclined design of the wind guide plate (19) enables it to generate axial wind force when rotating around the axis of the wire barrel (18), and form a negative pressure in the inner cavity of the wire twisting disk (12), sucking in fresh air from the outside and discharging it from the first ventilation groove (13), and discharging the heat absorbed by the heat conduction plate (21) through a continuous supply of wind energy, thereby enhancing the automatic heat dissipation effect of the device;

[0045] Since the power of the rotating shaft (16) driving the air guide plate (19) to rotate comes from the No. 3 gear (17), it is necessary to consider the problem of opposite directions generated when the eight groups of No. 3 gears (17) are meshed with each other for transmission, so the adjacent air guide plates (19) are arranged with opposite inclination directions.

[0046] The wire barrel (18) is made of chromium carbide wear-resistant steel, and an annular protrusion structure is provided at the end of the wire barrel (18) opposite to the transport direction of the conductor wire (4), the annular protrusion structure abuts against one end of the rotating shaft (16), and the wire barrel (18) is arranged on the inner wall of the rotating shaft (16) in an interference fit;

[0047] The wire barrel (18) is made of wear-resistant material and can greatly resist the wear caused by the conductor wire (4) when twisting the wire. The circular ring protrusion on the left end of the wire barrel (18) can produce a limiting abutment effect under the friction between the conductor wire (4) and the wire barrel (18), thereby preventing the wire barrel (18) from loosening, effectively improving the stability of the device. The wire barrel (18) is arranged in the rotating shaft (16) in an interference fit, which is also convenient for removal and replacement.

[0048] The outer surface of the conductor wire (4) is in frictional contact with the inner wall of the wire barrel (18) on the side facing the axis of the wire winding drum (12), and the right side of the inner wall of the wire barrel (18) is designed in an arc transition;

[0049] like Figure 5 As shown, the side of the conductor wire (4) that is in frictional contact with the inner wall of the wire barrel (18) faces the axis of the first gear (11), and the position where it contacts the inner wall of the wire barrel (18) is a line. As the wire barrel (18) rotates synchronously, the contact position periodically becomes the entire inner wall of the wire barrel (18).

[0050] Working principle:

[0051] When the wire twisting machine is working:

[0052] First, eight groups of conductor wires 4 are pulled out by the pay-off wheel and pulled through the conductor tube 3, the bracket 2 and the conductor barrel 18 to the right, and then gathered into the collecting barrel 7, and pulled and collected by the take-up wheel, forming a transport tension of the conductor wires 4 from left to right. Then, the motor 5 is started and the wire reel 12 is driven to rotate. At the same time, the eight groups of conductor wires 4 move synchronously to the right. As the wire reel 12 rotates, the eight groups of conductor wires 4 spirally gather to the right into the collecting barrel 7 and form a formed cable.

[0053] The inside of the wire winding disc 12 is rotating: the second gear 15 rotates around the axis of the first gear 11. Since the first gear 11 is fixed, the second gear 15 generates a rotational force, which is then transmitted to the third gear 17 meshing with the second gear 15. Then, the third gear 17 transmits the power to the remaining seven groups of third gears 17 in sequence. Since the diameter of the third gear 17 is greater than the diameter of the second gear 15, the speed of the third gear 17 will be lower than that of the second gear 15. The third gear 17 drives the rotating shaft 16 and The wire barrel 18 rotates synchronously, thereby converting the wire wear between the conductor wire 4 and the inner wall of the wire barrel 18 into uniform surface wear of the entire inner wall of the wire barrel 18. At the same time, the heat generated by the worn wire barrel 18 is transferred through the heat conduction plate 21. During the rotation of the rotating shaft 16, the air guide plate 19 will be driven to rotate synchronously, thereby generating a driving force for the air. The outside air will enter the interior of the wire twisting disk 12 through the No. 2 ventilation groove 14, and after driving the heat on the surface of the heat conduction plate 21, it will be discharged from the No. 1 ventilation groove 13, thereby realizing the synchronous heat dissipation function of the wire barrel 18.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
