Description

Technical Field

[0001] The invention relates to the technical field of circuit breaker production and processing, in particular to a wire drawing device for circuit breaker resistance wire. Background Art

[0002] Circuit breakers can not only close, carry and interrupt current under normal circuit conditions, but also close, carry and interrupt current under abnormal circuit conditions within a specified time. They can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Their function is equivalent to a combination of a fuse switch and an over- and under-temperature relay.

[0003] Resistance wire is one of the important structures in circuit breakers, usually including contact resistance, connection resistance and wiring resistance, etc. Therefore, when producing and processing circuit breakers, the corresponding resistors need to be processed, and the resistance wire needs to be drawn according to processing needs to achieve the appropriate diameter.

[0004] Patent publication number CN211161225U discloses a rough-pulling device for resistance wire processing. The device comprises a base, a heightening column, a fixed plate, and a movable plate. The movable plate is connected to the fixed plate via an electric telescopic rod. The fixed plate and movable plate are each provided with two rough-pulling wheels, which are staggered and arranged to perform rough-pulling on the resistance wire.

[0005] Patent publication number CN217665457U is a rough drawing device for resistance wire processing. Its structure mainly includes a support platform, a placement mechanism and a diameter-changing mechanism. The diameter-changing mechanism includes a support frame, a positioning roller, a connecting beam, a connecting frame, a support cylinder, and an adjustment cylinder. The support platform is provided with a support frame and a positioning roller. The placement mechanism is used to place the rough material and the finished product. The diameter-changing mechanism is used to adjust the inner hole diameter of one end of the support cylinder by rotating the adjustment cylinder. The required processing diameter can be quickly adjusted to improve work efficiency and enhance the use effect.

[0006] The above devices are all capable of drawing resistance wire, but they can only perform a single rough drawing process, so the drawing effect is poor. During the drawing process, there will be greater wear between the resistance wire and structures such as the roller, and the resistance wire is prone to breakage, which affects the drawing process.

[0007] Based on this, the present invention designs a wire drawing device for circuit breaker resistance wire to solve the above problems. Summary of the Invention

[0063] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0064] Example 1

[0065] Please refer to the accompanying drawings, the present invention provides a technical solution:

[0066] A wire drawing device for a circuit breaker resistance wire, such as Figure 1 As shown, it includes a base 100, and the top of the base 100 is provided with a first fixing frame 101, a second fixing frame 102 and a third fixing frame 103 from front to back, and each fixing frame is symmetrically provided with two;

[0067] A first wire drawing assembly is provided on the top of the first fixing frame 101, and a lubrication assembly is provided on the top of the first wire drawing assembly;

[0068] A second wire drawing assembly is provided on the top of the second fixing frame 102, a first adjustment assembly is provided on the front side of the second wire drawing assembly, a second adjustment assembly is provided on the rear side, and a lubrication recovery assembly is provided between the second adjustment assembly and the second wire drawing assembly;

[0069] A winding box 800 is provided on the top of the third fixed frame 103. The front side of the winding box 800 is set to be open, and a cooling assembly is provided on the inner front section. Two guide rollers 803 are symmetrically provided on both sides of the cooling assembly and are rotatably connected to the winding box 800.

[0070] like Figure 13As shown, a winding shaft 903 is provided in the middle of the inner rear section of the winding box 800, and a plurality of winding baffles 904 are evenly fixed on the winding shaft 903 along the length direction, and rotating shafts 902 are symmetrically fixed at both ends of the winding shaft 903. Drive components are correspondingly provided on the two side walls of the winding box 800, and the rotating shaft 902 is slidably connected to the drive component and is connected to a reciprocating moving component.

[0071] When the resistance wire is being drawn, multiple parallel resistance wires are unwound through an external unwinding device, and one end of the resistance wire passes through the first drawing assembly, the second drawing assembly, the lubrication recovery assembly, and the cooling assembly, and is then fixed to the corresponding position on the winding shaft 903. The resistance wire is wound and moved by the rotating winding shaft 903 and other structures, so that the resistance wire can move continuously and pass through the corresponding processing structure.

[0072] When the resistance wire passes through the first wire drawing assembly, it is first lubricated by the lubrication assembly to reduce the wear and tear on the resistance wire during the subsequent wire drawing process;

[0073] After lubrication, the resistance wire passes through the first wire drawing assembly for the initial wire drawing process to reduce the diameter of the resistance wire, and then the resistance wire continues to move and passes through the second wire drawing assembly for the secondary wire drawing process to further lengthen the resistance wire and reduce the diameter of the resistance wire;

[0074] The position of the resistance wire is adjusted by the first adjustment component and the second adjustment component in the front and rear positions of the second wire drawing component to improve the position accuracy of the resistance wire, thereby ensuring the uniformity of the resistance wire drawing and reducing damage and breakage of the resistance wire.

[0075] In the process of the resistance wire extending from the second wire drawing assembly and moving toward the second adjustment assembly, it passes through the lubrication recovery assembly so that the lubricating liquid on the resistance wire can be recovered by the lubrication recovery assembly to prevent the lubricating liquid from dripping onto other positions and structures during subsequent movement and winding of the resistance wire, causing waste of lubricating liquid, increased cleaning operations, etc., and the recovered lubricating liquid can be recycled and reused to improve the utilization rate of the lubricating liquid.

[0076] After completing two wire drawing processes, the resistance wire enters the winding box 800, and its position is adjusted by two guide rollers 803 so that the resistance wire can pass through the cooling component smoothly and be wound on the winding shaft 903. During the movement of the resistance wire, the cooling component is used to fully cool the resistance wire.

[0077] When the resistance wire is wound, the driving assembly on the winding box 800 rotates the rotating shaft 902 and the winding shaft 903, and then the resistance wire is wound. At the same time, the reciprocating moving assembly causes the winding shaft 903 to reciprocate within a certain length range. Through the coordination of rotation and movement, the resistance wire after drawing is evenly wound on the winding shaft 903, and the two resistance wires in adjacent positions are separated by the winding baffle 904.

[0078] Among them, Figure 5-8 As shown, the second wire drawing assembly includes a heating box 400 fixed on the top of two fixing frames. A plurality of wire drawing cylinders 401 are evenly arranged along the length of the heating box 400. The rear end of the wire drawing cylinder 401 is set to be conical, and a wire drawing tube 404 is fixed at the center of the rear end. The rear end of the wire drawing tube 404 extends out of the heating box 400.

[0079] The front end of the drawing tube 401 extends out of the heating box 400, and an annular limiting plate 405 is fixed on the outside of the extended section. A liquid-blocking ring 406 is provided inside the outer section of the drawing tube 401, and a vertical first liquid collecting pipe 402 is provided at the bottom of the drawing tube 401 corresponding to the position between the liquid-blocking ring 406 and the limiting plate 405, and the first liquid collecting pipe 402 is correspondingly connected to the lubrication recovery component.

[0080] When the resistance wire is subjected to secondary drawing, the drawing cylinder 401 is installed in the heating box 400 and connected to the outer wall of the heating box 400 through the limiting plate 405 to limit and fix the position of the drawing cylinder 401.

[0081] During operation, the resistance wire passes through the wire drawing cylinder 401 and the wire drawing tube 404. When passing through the wire drawing tube 404, the resistance wire is squeezed and stretched by the small-diameter wire drawing tube 404 to reduce the diameter of the resistance wire. While the wire drawing process is in progress, the wire drawing cylinder 401 and the wire drawing tube 404 are heated by the heating elements of the heating box 400, thereby heating the resistance wire during the wire drawing process, improving the tensile performance and reducing tensile wear.

[0082] During stretching, part of the lubricating liquid on the resistance wire is pushed down from the resistance wire and concentrated at the bottom of the drawing cylinder 401. The liquid-blocking ring 406 prevents the lubricating liquid from directly leaving the drawing cylinder 401, and the lubricating liquid is discharged through the first liquid collecting pipe 402 so that it can be recovered to the lubrication component to avoid waste of lubricating liquid.

[0083] Among them, Figure 7 、 Figure 8As shown, the lubrication recovery assembly includes end plates 600 symmetrically fixed to both sides of the rear end of the heating box 400, two parallel liquid collecting tanks 702 are provided between the end plates 600, a fixed mesh plate 707 is provided on the upper part of the inner cavity of the liquid collecting tank 702, a pressing plate 700 is provided above the liquid collecting tank 702, and an adsorption block 708 is provided on the top of the fixed mesh plate 707 and the bottom of the pressing plate 700 at the position corresponding to each drawing tube 404;

[0084] L-shaped telescopic frames 604 are symmetrically fixed at both ends of the liquid collecting tank 702. The horizontal section of the telescopic frame 604 passes through the end plate 600. The vertical section and the end plate 600 are connected by a telescopic hydraulic rod 706. Pressing blocks 704 are symmetrically fixed at both ends of the pressing plate 700. The pressing blocks 704 are connected to the horizontal section of the telescopic frame 604 on the corresponding side by a material pressing hydraulic rod 705.

[0085] A second collecting pipe 703 is provided at one side of the bottom of the collecting tank 702. The upper section of the second collecting pipe 703 is vertical, and the lower section is horizontal. The horizontal section is connected to the lubrication assembly.

[0086] A main recovery pipe 304 is fixed to the bottom of one end of the heating box 400, and the front end of the main recovery pipe 304 is connected to the corresponding lubrication assembly, and a first recovery branch pipe 403 is fixed on the main recovery pipe 304 at the front position corresponding to the heating box 400, and two second recovery branches 701 are fixed at the rear position corresponding to the heating box 400, and the bottom ends of multiple first collecting pipes 402 are connected to the top of the first recovery branch pipe 403, and the horizontal sections of the two second collecting pipes 703 are slidably connected to the corresponding second recovery branch pipe 701, so that the liquid collected by the first collecting pipe 402 and the second collecting pipe 703 can return to the lubrication assembly through the first recovery branch pipe 403, the second recovery branch pipe 701 and the recovery main pipe, and lubrication work is performed again.

[0087] After the resistance wire extends out of the heating box 400, it passes through the lubrication recovery assembly, and one of the liquid collecting tanks 702 and the pressure plate 700 does not perform the recovery work. The telescopic hydraulic rod 706 at the corresponding position drives the telescopic frame 604 and the liquid collecting tank 702 and the pressure plate 700 thereon to move, so that the position of the adsorption block 708 thereon is staggered with the position of the resistance wire. The pressure plate 700 and the adsorption block 708 on the liquid collecting tank 702 that participate in the lubrication recovery work are respectively in contact with the resistance wire. Therefore, during the movement of the resistance wire, the lubricating liquid on the resistance wire is adsorbed and recovered by the adsorption block 708;

[0088] When the adsorption block 708 absorbs a large amount of lubricating liquid, the telescopic frame 604 and the corresponding liquid collecting tank 702 and the pressure plate 700 are driven to move by the telescopic hydraulic rod 706, so that the position of the adsorption block 708 is offset from the position of the resistance wire. At the same time, the liquid collecting tank 702 and the pressure plate 700 on the other side are also driven to move by the corresponding telescopic hydraulic rod 706 and the telescopic frame 604, so that the adsorption block 708 on them contacts the resistance wire, so as to continue the lubrication recovery work of the resistance wire.

[0089] The pressure plate 700, which is offset from the position of the resistance wire, moves downward through the pressure hydraulic rod 705 at its end position, and squeezes the adsorption block 708 at the bottom of the pressure plate 700 and the top of the fixed mesh plate 707 through the pressure plate 700, and the squeezed lubricating liquid is concentrated in the collecting tank 702, and then recovered to the lubrication component through the second collecting pipe 703 and other structures for recycling, thereby reducing the waste of lubricating liquid.

[0090] Example 2

[0091] The structure of this embodiment is basically the same as that of the first embodiment, except that Figure 6 As shown, the first adjustment component includes two first adjustment rollers 500 symmetrically and vertically arranged on the front side of the drawing cylinder 401, and the top and bottom ends of the first adjustment rollers 500 are rotatably connected to the adjustment rods 501, and the rear ends of the adjustment rods 501 on the upper and lower sides are rotatably connected to the top and bottom of the heating box 400 respectively. The rear end of the adjustment rod 501 located at the top of the heating box 400 is fixed with an adjustment gear 502, and an adjustment rack 503 is commonly engaged between the two corresponding adjustment gears 502. The rear ends of the multiple adjustment racks 503 are commonly fixed with a vertical adjustment plate 504, and the two ends of the adjustment plate 504 are connected to the top of the heating box 400 through the adjustment hydraulic rod 505.

[0092] When the resistance wire passes through structures such as the heating box 400 and the wire drawing cylinder 401, the adjustment plate 504 and multiple adjustment racks 503 are driven to move by adjusting the hydraulic rod 505, so that multiple sets of adjustment gears 502 drive the adjustment rod 501 and the first adjustment roller 500 to rotate, and the corresponding two first adjustment rollers 500 move toward the direction of the resistance wire at the same time and contact both sides of the resistance wire, thereby adjusting and limiting the resistance wire on both sides in the vertical direction, so that the resistance wire and the central axis of the wire drawing cylinder 401 remain coincident, so that the resistance wire can smoothly pass through the wire drawing cylinder 401 and the wire drawing tube 404.

[0093] like Figure 6 、 Figure 8As shown, the second adjustment component includes a second adjustment roller 601 horizontally located between the rear sections of the two end plates 600, and a rectangular groove is provided on the end plate 600 at a position corresponding to the second adjustment roller 601, and a lifting block 602 is slidably connected in the rectangular groove. The bottom of the lifting block 602 is connected to the bottom end of the rectangular groove through a lifting hydraulic rod 603, and the two ends of the second adjustment roller 601 are respectively rotatably connected to the lifting blocks 602 on both sides.

[0094] After the resistance wire passes through the heating box 400 and the lubrication recovery assembly, the position of the lifting block 602 and the second adjustment roller 601 is adjusted by the lifting hydraulic rod 603, so that the horizontal height position of the resistance wire is adjusted through the contact between the second adjustment roller 601 and the resistance wire, thereby improving the accuracy of the resistance wire position.

[0095] Example 3

[0096] The structure of this embodiment is basically the same as that of the first embodiment, except that Figure 2-4 As shown, the first wire drawing assembly includes a first rotating roller 201 and a second rotating roller 202 that are symmetrically arranged and rotatably connected to the upper part of the first fixed frame 101, and one end of the first rotating roller 201 and the second rotating roller 202 are respectively connected to a motor, the first rotating roller 201 is located on the front side of the second rotating roller 202, and the lubrication assembly is located above the first rotating roller 201, and a horizontal plate 205 is provided on the inner side of the top of the first fixed frame 101, and a moving block 203 is connected to the bottom of the horizontal plate 205 through a moving hydraulic rod 204, and a pressure roller 200 is rotatably connected between the two moving blocks 203.

[0097] When the resistance wire passes through the first wire drawing assembly, it passes through the top of the first rotating roller 201, the bottom of the pressure roller 200 and the top of the second rotating roller 202 in sequence, and drives the moving block 203 and the pressure roller 200 to move downward by moving the hydraulic rod 204, adjusts the position of the pressure roller 200, and then drives the first rotating roller 201 and the second rotating roller 202 to rotate respectively through the machine, and the rotation speed of the second rotating roller 202 is greater than that of the second rotating roller 202, so that the resistance wire forms a differential movement between the first rotating roller 201 and the pressure roller 200, and between the pressure roller 200 and the second rotating roller 202, thereby achieving the purpose of stretching.

[0098] like Figure 4 As shown, the lubrication assembly includes a liquid infusion tube 300 located above the first rotating roller 201 and a liquid storage tank 301 located below the first rotating roller 201. Multiple rotating disks 307 are evenly arranged and rotatably connected on the liquid infusion tube 300. Multiple liquid outlet holes are evenly arranged on the circumferential side walls of the rotating disks 307. A liquid permeation layer is fixed on the outer side walls. A through hole is provided at the bottom of the liquid infusion tube 300 corresponding to the inner cavity position of each rotating disk 307.

[0099] The liquid storage tank 301 is fixed to the first fixing frame 101 at both ends. The liquid storage tank 301 is equipped with an infusion pump 305. The corresponding end of the infusion tube 300 is connected to the infusion pump 305. The top of the first fixing frame 101 is provided with a vertical spring groove. A vertical spring rod 302 is connected to the spring groove via a spring. The top end of the spring rod 302 extends out of the spring groove and is fixed to the infusion tube 300.

[0100] A filter screen 306 is fixed in the liquid storage tank 301, and a recovery pump 303 is provided at one end of the liquid storage tank 301 below the filter screen 306, and the front end of the recovery main pipe 304 is connected to the recovery pump 303 so that the recovered lubricating liquid can be filtered and reused, thereby reducing the impact of impurities on the infusion tube 300 and the rotating disk 307.

[0101] While the resistance wire moves along the top of the first rotating roller 201, the liquid permeation layer on the rotating disk 307 contacts the first rotating roller 201 and the top of the resistance wire, thereby rotating accordingly. During the rotation, the lubricating liquid delivered by the infusion tube 300 enters the bottom of the inner cavity of the rotating disk 307 through the through hole at the bottom thereof, and penetrates into the liquid permeation layer along the liquid outlet hole, thereby being evenly applied to the resistance wire through the liquid permeation layer, thereby achieving lubrication of the resistance wire and reducing wear during subsequent wire drawing processing;

[0102] A hose or spring tube is provided on the connecting section between the infusion tube 300 and the infusion pump 305 to adapt to the small movement of the spring rod 302 and the infusion tube 300, so that the bottom of the permeable layer on the rotating disk 307 can maintain contact with the first rotating roller 201 and the top of the resistance wire to ensure the lubrication effect.

After the sliding block 906 moves to one end of the screw 905, it moves in the opposite direction, thereby driving the sliding frame 901 and the movable frame 900 to move back and forth, and then the rotating shaft 902 and the winding shaft 903 move within a certain range, and cooperate with the rotation of the winding shaft 903 to make the resistance wire evenly reciprocatingly wound between the two winding baffles 904, making the winding more uniform.

[0107] like Figure 11 、 Figure 12 As shown, the driving assembly is rotatably connected to the rotating drum 804 on the side wall of the winding box 800, and a plurality of protrusions are evenly arranged in reverse directions along the circumference on the inner wall of the rotating drum 804, and a plurality of grooves are correspondingly provided on the side wall of the rotating shaft 902, and the protrusions are slidably connected in the corresponding grooves.

[0108] When it is necessary to rotate the rotating shaft 902 and the winding shaft 903, the transmission shaft 807 is rotated by the drive of the motor and the transmission of the first bevel gear 808 and the second bevel gear 809, and the rotating cylinder 804 is rotated by the transmission of the first pulley 805 and the second pulley 806, and then the rotating shaft 902 drives the winding shaft 903 to rotate through the cooperation of the protrusion and the groove, and the resistance wire after drawing is wound and collected.
