Description

Technical Field

[0001] The present invention belongs to the technical field of wire drawing machines and relates to a copper wire drawing machine that is convenient for adjustment and control. Background Art

[0002] Wire drawing machines are widely used in industries such as machinery manufacturing, hardware processing, petrochemical industry, plastics, bamboo and wood products, wire and cable, etc. They are important equipment for copper wire production. The aperture size of the wire drawing die, which is the core component, directly determines the diameter of a single copper wire. By finely adjusting the aperture of the wire drawing die, copper wire products with different diameters can be obtained.

[0003] For example, a Chinese patent with the application number 2024105062474 discloses a wire drawing machine for the production of ultra-fine copper wire; the technical solution disclosed in the patent document is as follows: including a machine body, on which there are an unwinding reel, a driving wheel, and a winding reel. Between the unwinding reel and the driving wheel, there are a driven wheel assembly and a die assembly. The unwinding reel, the driven wheel assembly, the die assembly, the driving wheel, and the winding reel are arranged in sequence from left to right on the front of the machine body.

[0004] In order to solve the problem of easy wire breakage in the existing structure, the prior art is to subject the wire on the cone pulley body to different pulling forces and reduce the wire winding speed of the wire winding wheel body to reduce the wire breakage rate. However, since the position of the die in the wire drawing machine is fixed, the diameter of the wire will decrease after passing through the die. During this process, a large acting force will be exerted on the wire at the wire inlet end of the die. When producing ultra-fine copper wire, wire breakage still occurs. For this reason, we propose a copper wire drawing machine that is convenient for adjustment and control. Summary of the Invention

[0005] The purpose of the present invention is to provide a copper wire drawing machine that is convenient for adjustment and control, which can solve the problems raised in the background art.

[0006] According to the technical solution provided by the present invention: a copper wire drawing machine that is convenient for adjustment and control includes a machine body, on which there are an unwinding reel, a driving wheel, and a winding reel; between the driving wheel and the winding reel, there are a driving wheel and a die mechanism; the unwinding reel, the driven wheel, the die mechanism, the driving wheel, and the winding reel are arranged in sequence from left to right on the front of the machine body;

[0007] The die mechanism includes a support plate arranged on the machine body. On the support plate, there is a first support plate. On the support plate, there is a second spring. The other end of the second spring is provided with a support block. On the support block, there is a cylinder; the cylinder is located inside the cylinder, and one end of the cylinder extends out of the first support plate and, under the compression of the second spring, drives the cylinder to reciprocate within the first support plate; on the support block, there are a die and two stretching components. When the second spring is compressed, the two stretching components are simultaneously stretched to cooperate with the reset of the second spring, causing the die to reciprocate.

[0008] Preferably, the stretching component includes a second support plate installed on the support plate. A second hinge rod is hinged on the second support plate. Cylinders are provided at the opposite ends of the second hinge rod. A drawing circle is slidably arranged in the cylinder. A pull rod is provided on the drawing circle. The opposite ends of the pull rod extend out of the cylinder and are provided with a first hinge rod. The opposite ends of the first hinge rod are jointly hinged with the support block. A third spring is provided between the opposite end inner wall of the support block and the cylinder. The third spring is sleeved on the outer side of the pull rod.

[0009] Preferably, three fixing plates are provided on the support block. Screws are screwed on each of the fixing plates. A first clamping plate is jointly screwed on the two lower screws. A second clamping plate is screwed on the upper screw. The cooperation of the second clamping plate, the first clamping plate and the fixing plate forms the support for the mold, and the mold can be replaced by rotating the screws.

[0010] Preferably, an adjusting plate push rod is provided on the second clamping plate. The left end of the adjusting plate push rod is provided with an adjusting component installed on the support plate. The left end of the adjusting plate push rod extends into the interior of the adjusting component, and when the adjusting plate push rod is moved, the parts inside the adjusting component are driven to move.

[0011] Preferably, for the adjusting component, the adjusting component includes a support frame installed on the support plate. Two telescopic rods and a first spring are provided on the support frame. An adjusting plate is jointly provided at the lower ends of the telescopic rod and the first spring. A pressure roller is provided at the lower end of the adjusting plate.

[0012] Preferably, the first spring is in a stretched state and is arranged between the two telescopic rods.

[0013] Preferably, two connecting rods are screwed at the lower end of the adjusting plate. A pressure roller is rotatably arranged between the two connecting rods. When the connecting rods are rotated, the distance between the pressure roller and the support plate can be adjusted.

[0014] Preferably, an inclined slot is provided on the adjusting plate. The left end of the adjusting plate push rod is arranged obliquely upward to cooperate with the inclined slot. When the adjusting plate push rod is pushed, the distance between the lower end of the adjusting plate and the support plate is adjusted.

[0015] Preferably, when the second spring is compressed to the maximum elastic force, the left end of the adjusting plate push rod is always located in the inclined slot, so that the left end of the adjusting plate push rod always forms a cooperation with the inclined slot and forms a support.

[0016] Preferably, a through hole is provided on the support block. The through hole on the support block, the through hole on the mold and the through hole on the cylinder are on the same horizontal line, and the through hole on the support block and the through hole on the cylinder have the same aperture, so as to ensure that the drawn copper wire can pass through quickly.

[0017] The positive and progressive effects of this application are as follows:

[0018] A copper wire drawing machine that is convenient for adjustment and control provided by an embodiment of the present invention has the following advantages:

[0019] 1. When the tensile force on the copper wire is too large, the copper wire pulls the die to move, causing the second spring to be gradually compressed and the third spring to be stretched. At this time, the tensile force on the copper wire gradually increases and will not increase instantaneously, effectively reducing the occurrence of wire breakage;

[0020] When the second spring is compressed, these two stretching components will be stretched simultaneously, and they accumulate energy during the stretching process; when the second spring returns to its original position, these two stretching components will release the previously accumulated energy, cooperate with the restoring force of the second spring, and jointly push the die to generate reciprocating motion.

[0021] 2. When the tensile force on the copper wire is too large, the die pulls the adjusting plate push rod to move, reducing the contact area between the adjusting plate push rod and the inclined groove. At this time, the first spring pulls the adjusting plate upward, driving the pressure roller to move upward, thereby reducing the pressure of the pressure roller on the copper wire, allowing the copper wire to be released for a certain distance, providing a buffer for the copper wire, and further reducing the risk of wire breakage.

Detailed Embodiments

[0029] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0031] As Figures 1-6 shown, the present invention is a copper wire drawing machine that is convenient for adjustment and control, including a machine body 1, on which an unwinding reel 11, a driving wheel 12, and a winding reel 14 are provided; a driving wheel 12 and a die mechanism are provided between the driving wheel 12 and the winding reel 14; the unwinding reel 11, the driven wheel 12, the die mechanism, the driving wheel 13, and the winding reel 14 are arranged in sequence from left to right on the front of the machine body 1.

[0032] The die mechanism includes a support plate 2 provided on the machine body 1. A first support plate 5 is provided on the support plate 2, and a second spring 501 is provided on the support plate 2. The other end of the second spring 501 is provided with a support block 502, and a cylinder 503 is provided on the support block 502; the cylinder 503 is located within the cylinder 503, and one end of the cylinder 503 extends out of the first support plate 5 and drives the cylinder 503 to reciprocate within the first support plate 5 under the compression of the second spring 501; two stretching components and a die 4 are provided on the support block 502.

[0033] When the second spring 501 is compressed, these two stretching components will be stretched simultaneously, and they accumulate energy during the stretching process; when the second spring 501 returns to its original position, these two stretching components will release the previously accumulated energy and cooperate with the restoring force of the second spring 501 to jointly push the die 4 to generate reciprocating motion.

[0034] In this embodiment, the stretching assembly includes a second support plate 510 mounted on the support plate 2. A second hinge rod 509 is hinged on the second support plate 510. A cylinder 505 is provided at the opposite end of the second hinge rod 509. A drawing circle 507 is slidably arranged in the cylinder 505. A pull rod 506 is provided on the drawing circle 507. The opposite ends of the pull rod 506 extend out of the cylinder 505 and are provided with a first hinge rod 504. The opposite ends of the first hinge rod 504 are jointly hinged to the support block 502. A third spring 508 is provided between the support block 502 and the inner wall of the opposite end of the cylinder 505. The third spring 508 is sleeved on the outer side of the pull rod 506.

[0035] When the tensile force on the copper wire is too large, the copper wire pulls the die 4 to move, and the second spring 501 is gradually compressed, and the third spring 508 is stretched. At this time, the tensile force on the copper wire gradually increases and will not increase instantaneously, which can effectively reduce the occurrence of wire breakage.

[0036] The two third springs 508 and the second spring 501 are in a T-shaped structure. First, when the tensile force of the copper wire is too large, resulting in excessive pressure at the contact end with the die 4, the third spring 508 and the second spring 501 will work together to absorb and disperse this part of the pressure. Since the compression of the second spring 501 is a gradual and smooth process, it is possible to more effectively avoid the instantaneous increase of pressure and further protect the copper wire from being pulled off.

[0037] Secondly, when the pressure disappears, the third spring 508 and the second spring 501 will reset synchronously. This synchronous reset characteristic ensures that the die 4 can quickly and stably return to the initial position to prepare for the next wire drawing operation.

[0038] More importantly, since the second spring 501 is connected to the die 4, during the reset process of the second spring 501, it will drive the die 4 to generate a reciprocating motion on the copper wire. This reciprocating motion has the following advantages:

[0039] Uniform stretching: The reciprocating motion helps the copper wire to be more evenly stressed during the stretching process, thus avoiding the situation of local over-stretching or under-stretching.

[0040] Improve quality: By uniform stretching, the quality of the copper wire can be significantly improved, including its strength, toughness and surface finish.

[0041] Reduce energy consumption: Since the reciprocating motion makes the stretching process more stable and continuous, the energy consumption and wear during the wire drawing process can be reduced.

[0042] Enhance stability: The T-shaped arrangement of the third spring 508 and the second spring 501 enhances the stability of the entire wire drawing system, making the system more robust and reliable in the face of changing loads.

[0043] Preferably, three fixing plates 62 are provided on the support block 502. Screws 61 are screwed onto the fixing plates 62. A first clamping plate 6 is jointly screwed onto the two lower screws 61, and a second clamping plate 63 is screwed onto the upper screw 61. The cooperation of the second clamping plate 63, the first clamping plate 6 and the fixing plate 62 forms the support for the mold 4, and the mold 4 can be replaced by rotating the screw 61.

[0044] First, rotate the upper screw 61 and remove the screw 61. Then rotate the two lower screws 61 to increase the distance between the three fixing plates 62 and the first clamping plate 6, so that the mold 4 can be removed and replaced.

[0045] Preferably, an adjusting plate push rod 64 is provided on the second clamping plate 63. An adjusting component is installed on the support plate 2 at the left end of the adjusting plate push rod 64. The left end of the adjusting plate push rod 64 extends into the interior of the adjusting component, and when the adjusting plate push rod 64 is moved, the parts inside the adjusting component are driven to move.

[0046] Preferably, for the adjusting component, the adjusting component includes a support frame 3 installed on the support plate 2. Two telescopic rods 31 and a first spring 32 are provided on the support frame 3. An adjusting plate 33 is jointly provided at the lower ends of the telescopic rod 31 and the first spring 32. A pressure roller 35 is provided at the lower end of the adjusting plate 33.

[0047] When the tension on the copper wire during production exceeds the preset safety range, this abnormal situation will trigger an automatic adjustment mechanism. Specifically, as an important component directly acting on the copper wire, when the abnormal increase in the tension felt by the mold 4 causes a slight displacement of the mold itself, this displacement is then converted into a pulling force on the adjusting plate push rod 64. The mold 4 pulls the adjusting plate push rod 64 to move along a predetermined trajectory.

[0048] As the adjusting plate push rod 64 moves, the relative position between it and the inclined groove 34 changes. The most intuitive manifestation is that the contact area gradually decreases. This change is the subtlety of the design because it can sensitively respond to the tension change and trigger subsequent adjustment actions through the change in geometric shape. The inclined groove 34 not only ensures the smooth and stable movement of the adjusting plate push rod 64 but also cleverly utilizes the mechanical properties of the inclined plane to convert the horizontal pulling force into a vertical displacement.

[0049] At the same time, the first spring 32, as a key elastic element, begins to play its role. When the adjusting plate 33 loses some support due to the movement of the adjusting plate push rod 64, the first spring 32 uses the elastic potential energy stored in it to start pulling the adjusting plate 33 upward. This action is fast and stable, ensuring the timeliness and accuracy of the adjustment process.

[0050] The upward movement of the adjusting plate 33 directly drives the upward movement of the pressure roller 35. The pressure roller 35 is a key component for applying pressure during the copper wire processing, and the change in its position directly affects the magnitude of the pressure on the copper wire. As the pressure roller 35 moves upward, the pressure it exerts on the copper wire gradually decreases. This change provides an immediate buffering effect for the copper wire, enabling the copper wire to be properly payed out a certain distance when the pulling force is too large, thereby effectively alleviating the potential risk of wire breakage caused by excessive pulling force.

[0051] Preferably, the first spring 32 is in a stretched state, and the first spring 32 is arranged between the two telescopic rods 31.

[0052] Preferably, two connecting rods are screwed to the lower end of the adjusting plate 33, and a pressure roller 35 is rotatably arranged between the two connecting rods. When the connecting rods are rotated, the distance between the pressure roller 35 and the support plate 2 can be adjusted.

[0053] Preferably, an inclined slot 34 is formed in the adjusting plate 33, and the left end of the adjusting plate push rod 64 is inclined upward to cooperate with the inclined slot 34. When the adjusting plate push rod 64 is pushed, the distance between the lower end of the adjusting plate 33 and the support plate 2 is adjusted.

[0054] Preferably, when the second spring 501 is compressed to the maximum elastic force, the left end of the adjusting plate push rod 64 is always located in the inclined slot 34, so that the left end of the adjusting plate push rod 64 always forms a cooperation with the inclined slot 34 and forms a support.

[0055] Preferably, the support block 502 is provided with a through hole. The through hole on the support block 502, the through hole on the mold 4 and the through hole on the cylinder 503 are on the same horizontal line, and the through hole on the support block 502 and the through hole on the cylinder 503 have the same aperture, so as to ensure that the drawn copper wire can pass through quickly.

[0056] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
