DETAILED DESCRIPTION

[0027] Embodiments of the present application are described below by way of example with reference to the accompanying drawings, in which like or similar elements are designated with the same or similar reference numerals, and the description is made by way of example only, not for limitation of the present application.

[0028] In the description of the present application, it needs to be understood that the orientation description, such as the left, right, etc. indicates the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and cannot be understood as indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0029] In the description of the present application, if there is a description of first, second, etc. for the purpose of distinguishing technical features, it cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0030] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0031] like Figures 1 to 9 As shown, the present invention provides a wire drawing machine, including a frame 10, a wire drawing mechanism 11, a wire take-up mechanism and a braking mechanism 12. A wire drawing mechanism 11 is mounted on a frame 10 and is used to process the outer diameter of the wire to a set size. A take-up mechanism is used to receive the processed wire and includes a take-up reel 13 rotatably mounted on the frame 10. The take-up reel 13 is removable for replacement. A braking mechanism 12 includes a pneumatic component 14, a first clamping arm, a second clamping arm, a first brake block 19, and a second brake block 20. The first clamping arm includes a first segment 15 and a second segment 16 arranged at an angle, where the angle between the first segment 15 and the second segment 16 is neither zero nor 180 degrees, and the first segment 15 and the second segment 16 are approximately perpendicular. The second clamping arm includes a third segment 17 and a fourth segment 18 arranged at an angle, where the angle between the third segment 17 and the fourth segment 18 is neither zero nor 180 degrees, and the third segment 17 and the fourth segment 18 are approximately perpendicular. The first segment 15 is arranged vertically, and the middle of the first segment 15 is connected by a first rotating... Shaft 21 is pivotally connected to frame 10. At this time, the installation position of brake mechanism 12 and frame 10 is located in the middle of the side of brake mechanism 12, which can effectively reduce the space occupied by brake mechanism 12 in the vertical direction. One end of third section 17 is pivotally connected to first shaft 21 or first section 15 above first shaft 21, and the other end of third section 17 is connected to fourth section 18. First brake block 19 is pivotally connected to the lower end of first section 15, second brake block 20 is pivotally connected to the lower end of fourth section 18, second section 16 is connected to the upper end of first section 15, pneumatic component 14 is installed on second section 16, and the output end of pneumatic component 14 acts on third section 17. An elastic component is provided between second section 16 and second clamping arm to make first brake block 19 and second brake block 20 move away from each other. The elastic component can be set as a spring. A first hook 22 is provided at the tail of second section 16, and a second hook 23 is provided at the upper part of fourth section 18. The first hook 22 and the second hook 23 are connected to the two ends of the spring. It should be noted that the elastic element can also be set as a rubber strip or other elastic components.

[0032] When the third segment 17 is pivoted to the first pivot 21, the third segment 17, the first segment 15 and the frame 10 are pivoted to the first pivot 21, which is simple and compact. When the third segment 17 is pivoted to the first segment 15 above the first pivot 21, the pivoted position is further away from the lower end of the first segment 15, which means that the displacement of the upper end of the first segment 15 can be transmitted to the lower end of the first segment 15 in a larger proportion, so that the lower end of the first segment 15 rotates a larger displacement, thereby reducing the driving stroke, and thereby reducing the space required for the operation and installation of the brake mechanism 12.

[0033] The brake mechanism 12 described above is compact in structure when the first segment 15 and the third segment 17 are assembled in parallel, the second segment 16 and the third segment 17 are assembled in parallel, and the driving stroke can be effectively amplified, and the requirement for the driving stroke is reduced. The first clamping arm is a one-piece structure, the second clamping arm is a one-piece structure, and the manufacturing is convenient, and the brake mechanism 12 only needs fewer parts, and the structure is very simple and compact. The specific action process of the brake mechanism 12 is as follows: when braking is needed, the pneumatic part 14 is connected to high-pressure gas, the high-pressure gas drives the output end of the pneumatic part 14 to press down the third segment 17, so that the second segment 16 and the third segment 17 are far away, and then the first segment 15 and the fourth segment 18 are close to each other, the first brake block 19 and the second brake block 20 are close to each other to clamp the driving mechanism to form braking; when the brake needs to be released, the pneumatic part 14 is depressurized, and under the action of the elastic part, the first segment 15 and the fourth segment 18 move away from each other, driving the first brake block 19 and the second brake block 20 to move away from each other, thereby releasing the brake.

[0034] As Figure 2 and Figure 6As shown, specifically, in some embodiments of the present application, the pneumatic element 14 comprises a housing 24, a cavity 25 is arranged in the housing 24, and a gas inlet 26, a first channel 27 and a second channel 28 are arranged on the housing 24 and communicate with the cavity 25; the first channel 27 is arranged at the upper end of the housing 24, and the first channel 27 is arranged in an up-down manner, the upper end of the first channel 27 is in a conical shape, the lower end of the first channel 27 is in a cylindrical shape, and a screen is arranged at the lower end of the first channel 27, and a sealing ball 29 is arranged in the first channel 27 and cooperates with the upper end of the first channel 27; when high-pressure gas enters the gas inlet 26, the sealing ball 29 is blown to the upper end of the first channel 27 and cooperates with the conical surface to close the first channel 27; the second channel 28 is arranged at the lower end of the housing 24, and the second channel 28 is arranged in an up-down manner, the second channel 28 is in a stepped hole shape, and a working rod 30 is arranged in the second channel 28 and cannot slide out of the second channel 28, the lower end of the working rod 30 is in a spherical shape, and the third section 17 is provided with an arc-shaped working surface 31 corresponding to the working rod 30; after the first channel 27 is closed, the high-pressure gas pushes the working rod 30 to move downward to extrude the third section 17, so that the third section 17 is away from the second section 16; after the gas inlet 26 is depressurized, the sealing ball 29 falls under the action of gravity and no longer cooperates with the conical surface, so that the first channel 27 is opened, the working rod 30 no longer exerts pressure downward, and the third section 17 and the second section 16 approach each other under the action of the elastic element. The pneumatic element 14 with the above structure only needs to pass high-pressure gas in the forward direction or be depressurized, and does not need to pass high-pressure gas in the reverse direction, which can effectively reduce the working stroke and size of the pneumatic element 14 and is beneficial to reducing the complexity of the overall structure.

[0035] As shown in Figure 2 and Figure 6 In some embodiments of the present application, the rack 10 is provided with a first clamping assembly and a second clamping assembly for clamping the take-up reel 13, the first clamping assembly has a first clamping shaft 32 capable of rotating, the first clamping shaft 32 is in transmission connection with a second motor 34, the second clamping assembly has a second clamping shaft 33 capable of rotating, the second clamping shaft 33 can approach or move away from the first clamping shaft 32, the take-up reel 13 has a plug-in hole 35 penetrating through the middle, and the first clamping shaft 32 and the second clamping shaft 33 respectively extrude two ends of the plug-in hole 35 to clamp the take-up reel 13. The above-mentioned first clamping assembly and second clamping assembly can be suitable for clamping a take-up reel 13 with a larger size, the larger the size of the take-up reel 13, the more wire it can collect, and the heavier the weight; compared with the cantilever structure of the transmission, the clamping mode of the two ends of the take-up reel 13 in the present embodiment can effectively improve the clamping stability and can bear a larger weight.

[0036] As shown in Figure 3 and Figure 4As shown, in some embodiments of the present invention, the second clamping assembly further includes a second mounting tube 36, a first bearing 37, a second bearing 38, a sliding tube 39, an intermediate ring 40, a fourth cylinder 41, and a fifth cylinder 42. The second mounting tube 36 is fixedly mounted on the frame 10, and the sliding tube 39 is slidably inserted into the second mounting tube 36. The sliding tube 39 has three sections of first stepped shaft holes, with the middle first stepped shaft hole having the smallest inner diameter. The first bearing 37 and the second bearing 38 are respectively disposed in the first stepped shaft holes at both ends. One end of the holding shaft 33 is fitted with the first bearing 37 and the second bearing 38, while the other end is located outside the sliding tube 39. An intermediate ring 40 is positioned in the first stepped shaft hole away from the take-up reel to press against the first bearing 37. The sliding tube 39 is equipped with a first end cap 43 to seal the stepped shaft. A fourth cylinder 41 is mounted on the frame 10, and its output end is connected to the first end cap 43. A fifth cylinder 42 is mounted on the frame 10, positioned perpendicular to the sliding tube 39, and its output shaft engages with the first end cap 43. The first bearing 37 can be an angular contact ball bearing, effectively bearing axial and radial forces. The second bearing 38 can be a cylindrical roller bearing, ensuring smooth rotation of the second holding shaft 33.

[0037] The sliding tube 39 slides, causing the second clamping shaft 33 to slide. The right end of the second clamping shaft 33 has a frustum-shaped second clamping part, which is connected to the insertion hole 35. The first bearing 37 is fixed in the first stepped shaft hole by the intermediate ring 40 and the first end cover 43. In this way, the first bearing 37 can provide a thrust along the center line of the second clamping shaft 33 so that the second clamping shaft 33 can clamp the take-up reel 13. The operation of the fourth cylinder 41 can push the sliding tube 39 to slide. After the fourth cylinder 41 pushes the sliding tube 39 to clamp the take-up reel 13, the fifth cylinder 42 operates so that the output shaft of the fifth cylinder 42 extends to the left side of the first end cover 43 to prevent the first end cover 43 from moving to the left. This avoids the situation where the sliding tube 39 moves to the left due to the failure of the fourth cylinder 41, which can effectively improve the safety of the wire drawing machine.

[0038] like Figure 3 As shown, in some embodiments of the present invention, mounting rings 44 are provided at both ends of the second mounting tube 36. The mounting rings 44 are made of copper, which has good wear resistance. In this embodiment, the second mounting tube 36 does not directly contact the sliding tube 39, but the mounting rings 44 do. An annular lubrication groove 45 is provided on the inner side of the mounting ring 44, and an oiling hole 46 is provided on the side wall of the mounting ring 44. The oiling hole 46 communicates with the lubrication groove 45 and is used to add lubricating oil, further improving the wear resistance of the mounting ring 44. In addition, even if the mounting ring 44 wears out after long-term use, only the mounting ring 44 needs to be replaced, and the second mounting tube 36 does not need to be replaced, which facilitates later maintenance and reduces maintenance costs.

[0039] As shown in Figure 5 some embodiments of the present application, the first clamping assembly includes a first mounting tube 47, a third bearing 48, a fourth bearing 49, a second end cover 50, the first clamping shaft 32 has a first clamping portion in the shape of a circular truncated cone at the right end, the first clamping portion is in butt joint with the plug-in hole 35, the first mounting tube 47 is fixedly installed on the rack 10, the first mounting tube 47 is provided with three second stepped shaft holes, the inner diameter of the middle second stepped shaft hole is the smallest, the third bearing 48 and the fourth bearing 49 are arranged in the two end second stepped shaft holes respectively, one end of the first clamping shaft 32 is installed in cooperation with the third bearing 48 and the fourth bearing 49, and the other end is located outside the first mounting tube 47, and the second end cover 50 is used for closing both ends of the first mounting tube 47 and extruding the third bearing 48 and the fourth bearing 49. Among them, the third bearing 48 can adopt an angular contact ball bearing, which can effectively bear the axial and radial external force, and the fourth bearing 49 can adopt a cylindrical roller bearing, so that the first clamping shaft 32 can rotate smoothly. The third bearing 48 in the first clamping assembly with the above structure can provide a supporting force along the center line direction of the first clamping shaft 32 for the first clamping shaft 32, so that the first clamping shaft 32 can be used for clamping the take-up reel 13. The first clamping assembly with the above structure is compact, stable and reliable in work.

[0040] As shown in Figure 5 and Figure 6 some embodiments of the present application, the brake mechanism 12 further includes a brake piece 51, the brake piece 51 is connected with the first clamping shaft 32, and the brake piece 51 is located between the first brake block 19 and the second brake block 20; the second section 16 is provided with a first mounting hole, a protrusion along the center line of the first mounting hole is arranged on the inner side wall of the first mounting hole, the lower end of the pneumatic piece 14 is provided with a mounting column, the upper end of the mounting column has a groove matched with the protrusion, the lower end of the mounting column is provided with a thread, the lower end of the mounting column is screwed with a nut after penetrating through the first mounting hole, and the second channel 28 is located in the mounting column. The cooperation of the protrusion and the groove can make the pneumatic piece 14 unable to rotate relative to the second section 16, so as to facilitate the screwing of the nut at the lower end of the mounting column. The pneumatic piece 14 with the above structure is very convenient to install.

[0041] As shown in Figure 8As shown, in some embodiments of the present invention, the wire drawing mechanism 11 includes a first motor 52, four pulleys, and a die holder 71.

The wire drawing mechanism 11 has a compact overall structure, facilitating subsequent spraying; the four pulleys are driven by a first motor 52, resulting in high operational coordination and saving on power source costs.

[0042] like Figure 6 As shown, in some embodiments of the present invention, the frame 10 is equipped with a water tank 72, a water pump 73, and a spray assembly. A baffle is provided below the wire drawing mechanism 11 on the frame 10. The baffle collects spray water and has a drain hole that communicates with the water tank 72. The spray water collected by the baffle is discharged from the drain hole into the water tank 72. The spray assembly includes a main pipe 74 and six branch pipes 75. The input end of the water pump 73 is connected to the water tank 72, and the output end of the water pump 73 is connected to the main pipe 74. The main pipe 74 is also connected to the six branch pipes 75. A branch pipe 75 is provided above each tower wheel and each eye mold base 71. The above-mentioned spray assembly can provide spraying at multiple locations simultaneously. It has a simple and practical structure, efficient spray water circulation, and is energy-saving and environmentally friendly.

[0043] like Figure 7As shown, in some embodiments of the present application, the rack 10 is further provided with a tension adjusting mechanism, which comprises a mounting plate 76, a third cylinder 77, a chain, a first roller 78, a second roller 79, a connecting block 80, a movable sprocket 81, a fixed sprocket 82 and a sliding seat 83. The first roller 78 is rotatably mounted on the mounting plate 76, which is mounted on the rack 10. The mounting plate 76 can be an integral structure with the rack 10 or can be independently mounted on the rack 10. Two parallel sliding rods are mounted on the mounting plate 76, and the sliding seat 83 is slidingly mounted on the sliding rods. The second roller 79 is connected with a second rotating shaft 85. The sliding seat 83 is provided with a second mounting hole 84, a first threaded hole and a second threaded hole. The first threaded hole and the second threaded hole are perpendicular to the second mounting hole 84, and the first threaded hole is in communication with the second mounting hole 84. One end of the second rotating shaft 85 is inserted into the second mounting hole 84, and a screw is threaded into the first threaded hole to press the second rotating shaft 85, thereby mounting and locking the second rotating shaft 85. The connecting block 80 is provided with a third mounting hole, and a bolt is threaded into the third mounting hole and the second threaded hole to mount the connecting block 80 on the sliding seat 83. The connecting block 80 is further provided with a fourth threaded hole. The third cylinder 77 is mounted on the mounting plate 76. The movable sprocket 81 is rotatably mounted on the output end of the third cylinder 77. The fixed sprocket 82 is rotatably mounted on the mounting plate 76. One end of the chain is connected with the mounting plate 76, and the other end of the chain is connected with the connecting block 80 after passing through the movable sprocket 81 and the fixed sprocket 82. The other end of the chain is provided with a connecting rod, which is threadedly connected with the fourth threaded hole. The force exerted by the third cylinder 77 is amplified by the movable sprocket 81 and can act on the sliding seat 83 with twice the force, thereby reducing the cost of the third cylinder 77. The assembly of the sliding seat 83, the connecting block 80, the chain and the second rotating shaft 85 is very simple and ingenious, which is conducive to improving the assembly efficiency. The wire processed by the wire drawing mechanism 11 enters the tension adjusting mechanism. The wire is wound around the first roller 78 and the second roller 79 and is collected by the take-up reel 13. The tension of the wire can be adjusted by the third cylinder 77.

[0044] As Figure 9As shown, in some embodiments of the present application, the take-up reel 13 has a large overall weight of up to several hundred kilograms after receiving the wire, which is difficult and unsafe to lift manually. Therefore, the frame 10 is provided with a lifting mechanism for lifting the take-up reel 13. The lifting mechanism includes a tray 86, a lifting plate 87, a first cylinder 88, a second cylinder 89, a mounting seat 90, and a limiting rod 91. The two ends of the first cylinder 88 are fixedly connected with the mounting seat 90 and the lifting plate 87, respectively. The mounting seat 90 includes a vertical portion and a horizontal portion which are perpendicular to each other. The horizontal portion is connected with the first cylinder 88, and the vertical portion is connected with the frame 10. The horizontal portion is provided with a fifth threaded hole. The limiting rod 91 is provided with a thread on the outside which cooperates with the fifth threaded hole. The limiting rod 91 can abut against the housing of the first cylinder 88 when following the output end of the first cylinder 88 to lift. The tray 86 includes a horizontal load-bearing plate and a vertical plate which is vertically arranged. The load-bearing plate is used to bear the take-up reel 13. The vertical plate is provided at the upper end with a horizontal plate which is perpendicular to the vertical plate. The second cylinder 89 is connected at one end with the horizontal plate and at the other end with the lifting plate 87. A reinforcing rib 93 is arranged between the horizontal plate and the vertical plate to increase the overall structural strength.

[0045] The above-mentioned lifting mechanism can facilitate the take-up reel 13 to rise to be aligned with the first clamping shaft 32 and the second clamping shaft 33 for installation. After the take-up reel 13 completes winding, the lifting mechanism is used to receive the take-up reel 13 and move it downward. The first cylinder 88 and the second cylinder 89 can provide two-stage driving for the tray 86, which is very convenient and flexible. By adjusting the size of the limiting rod 91 passing through the fifth threaded hole, the stroke of the first cylinder 88 can be adjusted to be suitable for take-up reels 13 of different sizes.

[0046] In addition, a carrying trolley 92 can also be placed on the load-bearing plate. After the take-up reel 13 is placed on the carrying trolley 92, the fork rod of a forklift is extended into the lower part of the carrying trolley 92. At this time, the tray 86 is lowered again to avoid interference between the carrying trolley 92 and the tray 86. Then the forklift translates the carrying trolley 92 out, so that the take-up reel 13 can be moved out.
