Description

Technical Field

[0001] The utility model relates to the technical field of metal processing equipment, in particular to an automatic regulating metal wire drawing control device. Background Art

[0002] The metal wire drawing process is a technical processing method that uses pressure processing to force metal materials through a die, thereby changing their cross-sectional area, shape and size. In terms of development prospects, with the increasing attention of the science and technology industry and the continuous upgrading of market demand, it is expected that the performance of wire drawing machines will be further optimized in the future, including improving processing speed and precision. With the development and application of new metal materials, the wire drawing process is expected to meet the market demand for higher quality and higher cost performance. Through technological innovation and process improvement, it still has broad development potential.

[0003] In the prior art, during the production process of metal wire drawing devices, it is often necessary to cut the drawn metal wire in order to achieve the required length or to prepare for subsequent processing steps. In these cases, a commonly used cutting method is the pressure cutting method, which has a working principle similar to that of a vise, that is, the metal wire is clamped and cut by applying a certain pressure. Since the metal is subjected to extrusion force during the cutting process, the end of the metal wire will be deformed. This deformation makes the cross-section of the metal wire not a regular circle, but an irregular shape, which makes it difficult for the equipment to control the shape of the cross-section at the end of the metal wire. This irregular cross-section will bring difficulties to the subsequent processing steps, because the irregular cross-section will affect the connection, assembly or further processing of the metal wire, thereby increasing production costs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an automatic regulating metal wire drawing control device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatically adjustable metal wire drawing control device, including a processing device, a wire drawing die is fixed inside the processing device, a plurality of die holes are opened on the surface of the wire drawing die, the die holes include a second diameter hole and a first diameter hole, a fixing ring is fixed on the inner wall of the die hole, a linear array of countersunk grooves are opened on the inner wall of the wire drawing die, a second gear is rotatably connected to the inner wall of the countersunk groove at the second diameter hole, a first gear is rotatably connected to the inner wall of the countersunk groove at the first diameter hole, the second gear tooth groove is meshed with the first gear tooth groove, an inclined slide groove is opened on the top linear array of the first gear, and the The inner wall of the inclined slide groove is slidably connected with a shaft column, the circumference of the shaft column is rotatably connected with an extension rod, a cutting knife is fixed at one end of the extension rod, a buckle cylinder is fixed on the side of the cutting knife, the inner wall of the buckle cylinder is rotatably connected with the shaft column, and the bottom of the shaft column is fixed to the top of the fixing ring. In the prior art, during the production process of metal wire drawing devices, it is often necessary to cut the drawn metal wire to achieve the required length or to prepare for subsequent processing steps. In these cases, a commonly used cutting method is a pressure cutting method, and its working principle is similar to that of a vise, that is, a certain pressure is applied to clamp and cut the metal wire. Since the metal is affected during the cutting process, Due to the extrusion force, the end of the metal wire will be deformed. This deformation makes the cross-section of the metal wire not a regular circle, but an irregular shape, which makes it difficult for the equipment to control the shape of the cross-section of the end of the metal wire. This irregular cross-section will bring difficulties to the subsequent processing steps, because the irregular cross-section will affect the connection, assembly or further processing of the metal wire, increasing the production cost. In view of such problems, the utility model adopts the method of installing a cutting knife to solve it, so that when the staff needs to cut the metal wire, the motor is started, and the motor drives multiple gears to mesh and rotate, so that the second gear meshes and drives the first gear to rotate in the reverse direction. The clockwise rotation causes the inclined slide to push the shaft column to move toward the end of the inclined slide closer to the center of the circle through friction, and at the same time the buckle cylinder rotates with the shaft column as the axis, and multiple cutting knives all rotate counterclockwise with the shaft column as the axis, quickly gather toward the center of the first diameter hole, and quickly cut the metal wire with their own blades. Due to the coordination of multiple cutting knives, the distance that each cutting knife cuts into the metal wire is not deep, which reduces the wear of the cutting knives and makes it easy for the staff to control the cross-section of the metal wire to remain circular. In addition, the staff can adjust the output power of the motor according to the different metal materials to make the device automatically adjust the cutting force, so as to improve the yield rate and reduce the production cost.

[0006] Preferably, a reserved groove is provided on one side of the extension rod. In the prior art, since the material will produce elastic deformation during extrusion, it is easy to cause the extension rod and the buckle barrel to collide, thereby causing scratches and damage to the component. The scratches on the surface will cause the protective layer on the surface of the component to fall off, and air and water vapor will more easily react with the internal material, resulting in accelerated component damage and reduced equipment life. To address such problems, the utility model adopts a method of providing a reserved groove to solve the problem, so that when the metal wire is cut, if elastic deformation occurs, the buckle barrel can move toward the reserved groove. The reserved groove provides sufficient space, so that even if the metal is deformed, the buckle barrel will not collide with the extension rod, thereby avoiding hard contact that may damage the equipment, while also ensuring the smooth progress of the cutting process, thereby achieving the effect of increasing the service life of the equipment.

[0007] Preferably, both ends of the inclined slide are set to be semicircular. In the prior art, in the cutting process of the metal wire drawing device, in order to ensure that the metal wire is cut quickly and accurately, a large cutting force is usually used. This force can cut the metal wire in a short time and at the same time ensure that the cross section is in a perfect circular state. The shaft column is located in the inclined slide and moves rapidly along the inner wall of the inclined slide under the action of the cutting force. This rapid movement enables the cutting knife connected to the shaft column to quickly cut the metal wire. When the shaft column reaches the two ends of the inclined slide, it will collide with the inclined slide. This collision is caused by the sudden stop of the shaft column at the end of the inclined slide during high-speed movement. Each collision will cause a certain degree of impact and wear on the shaft column and the inclined slide. In the long run, this impact and wear will lead to a reduction in the service life of the components. In response to such problems, the utility model adopts a semicircular method to solve the problem, so that when the shaft column moves to one end of the inclined slide, the semicircle is closely fitted with the circle of the shaft column, so that the contact area is greatly increased, the pressure on the surfaces of the two is greatly reduced, and the wear is also greatly reduced, so as to achieve the effect of increasing the service life of the equipment.

[0008] Preferably, triangular fasteners are fixed at both ends of the wire drawing die, and the back of the triangular fasteners is fixed to the inner wall of the processing equipment. The triangular fasteners make the wire drawing die and the processing equipment present a stable triangular state, thereby improving the stability of the component.

[0009] Preferably, the cross-section of the first gear tooth is set to a trapezoid, which increases the contact area between the first gear tooth and the second gear tooth groove, reduces the impact of pressure on both, prevents surface deformation, and increases the service life of the equipment.

[0010] Preferably, the diameter of the reserved groove is larger than the diameter of the buckle barrel, so as to provide the buckle barrel with sufficient anti-collision space and improve the safety of equipment use.

[0011] Preferably, the front edge of the wire drawing die is set to be cut corners to reduce the weight of the wire drawing die close to the front side, so that its center of gravity is as close to the equipment as possible to prevent the component from falling.

[0012] Beneficial Effects

[0013] 1. In the prior art, in the production process of metal wire drawing devices, it is often necessary to cut the drawn metal wire to achieve the required length or to prepare for subsequent processing steps. In these cases, a commonly used cutting method is a pressure cutting method, which works similarly to a vise, that is, clamping and cutting the metal wire by applying a certain pressure. Since the metal is subjected to extrusion force during the cutting process, the end of the metal wire will be deformed. This deformation makes the cross-section of the metal wire not a regular circle, but an irregular shape, which makes it difficult for the device to control the shape of the cross-section at the end of the metal wire. This irregular cross-section will bring difficulties to the subsequent processing steps, because the irregular cross-section will affect the connection, assembly or further processing of the metal wire, increasing the production cost. In view of such problems, the present invention is a method for cutting metal wires. The new method of installing a cutting knife is used to solve the problem. When the staff needs to cut the metal wire, the motor is started, and the motor drives multiple gears to mesh and rotate, so that the second gear meshes and drives the first gear to rotate counterclockwise, so that the inclined slide pushes the shaft column to move toward the end of the inclined slide column close to the center of the circle through friction. At the same time, the buckle cylinder rotates with the shaft column as the axis, and multiple cutting knives all rotate counterclockwise with the shaft column as the axis, and quickly gather to the center of the first diameter hole, and quickly cut the metal wire with their own blades. Due to the coordination of multiple cutting knives, the distance that each cutting knife cuts into the metal wire is not deep, which reduces the wear of the cutting knives. At the same time, it is convenient for the staff to control the cross-section of the metal wire to remain circular, and the staff can adjust the output power of the motor according to the different metal materials to make the device automatically adjust the cutting force, so as to achieve the effect of improving the yield rate and reducing the production cost.

[0014] 2. In the prior art, since the material will produce elastic deformation during extrusion, it is easy to cause the extension rod and the buckle tube to collide, thereby causing the component to be scratched and damaged. The scratches on the surface will cause the protective layer on the surface of the component to fall off, and air and water vapor will more easily react with the internal material, resulting in accelerated component damage and reduced equipment life. To address this problem, the utility model adopts a method of opening a reserved groove to solve it. When the metal wire is cut off, if elastic deformation occurs, the buckle tube can move toward the reserved groove. The reserved groove provides sufficient space, so that even if the metal is deformed, the buckle tube will not collide with the extension rod, thereby avoiding hard contact that may cause damage to the equipment. At the same time, it also ensures the smooth progress of the cutting process, thereby achieving the effect of increasing the service life of the equipment.

[0015] 3. In the prior art, in the cutting process of the metal wire drawing device, in order to ensure that the metal wire is cut quickly and accurately, a large cutting force is usually used. This force can cut the metal wire in a short time and at the same time ensure that the cross section is in a perfect circular state. The shaft column is located in the inclined slide groove and moves rapidly along the inner wall of the inclined slide groove under the action of the cutting force. This rapid movement enables the cutting knife connected to the shaft column to quickly cut the metal wire. When the shaft column reaches the two ends of the inclined slide groove, it will collide with the inclined slide groove. This collision is caused by the sudden stop of the shaft column at the end of the inclined slide groove during high-speed movement. Each collision will cause a certain degree of impact and wear on the shaft column and the inclined slide groove. In the long run, this impact and wear will lead to a reduction in the service life of the components. In view of such problems, the utility model adopts a semicircular method to solve the problem, so that when the shaft column moves to one end of the inclined slide groove, the semicircle and the circle of the shaft column are closely fitted, so that the contact area is greatly increased, the pressure on the surfaces of the two is greatly reduced, and the wear is also greatly reduced, so as to achieve the effect of increasing the service life of the equipment.

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:

[0025] Reference Figure 1-4An automatic regulating metal wire drawing control device comprises a processing device 1, wherein a wire drawing die 101 is fixed inside the processing device 1, a plurality of die holes are provided on the surface of the wire drawing die 101, the die holes include a second diameter hole 102 and a first diameter hole 103, a fixing ring 203 is fixed on the inner wall of the die hole, a linear array of countersunk circular grooves 2 are provided on the inner wall of the wire drawing die 101, a second gear 201 is rotatably connected to the inner wall of the countersunk circular groove 2 at the second diameter hole 102, a first gear 202 is rotatably connected to the inner wall of the countersunk circular groove 2 at the first diameter hole 103, a tooth groove of the second gear 201 is meshed with a tooth groove of the first gear 202, an inclined slide groove 204 is provided on the top of the first gear 202 in a linear array, and the inner wall of the inclined slide groove 204 slides A shaft column 205 is connected, and an extension rod 206 is rotatably connected to the circumference of the shaft column 205. A cutting knife 208 is fixed to one end of the extension rod 206. A buckle tube 209 is fixed to the side of the cutting knife 208. The inner wall of the buckle tube 209 is rotatably connected to the shaft column 205. The bottom of the shaft column 205 is fixed to the top of the fixing ring 203. In the production process of the metal wire drawing device, it is often necessary to cut the drawn metal wire to achieve the required length or to prepare for subsequent processing steps. In these cases, a commonly used cutting method is the pressure cutting method, and its working principle is similar to that of a vise, that is, by applying a certain pressure to clamp and cut the metal wire. Since the metal is squeezed during the cutting process, The force is applied, so the end of the wire will be deformed. This deformation makes the cross section of the wire not a regular circle, but an irregular shape, which makes it difficult for the equipment to control the shape of the cross section of the end of the wire. This irregular cross section will bring difficulties to the subsequent processing steps, because the irregular cross section will affect the connection, assembly or further processing of the wire, increasing the production cost. The problem is solved by installing a cutting knife 208, so that when the staff needs to cut the wire, the motor is started, and the motor drives multiple gears to mesh and rotate, so that the second gear 201 meshes and drives the first gear 202 to rotate counterclockwise, so that the inclined slide 204 is pushed by friction. The shaft column 205 moves toward the end of the inclined slide groove 204 close to the center of the circle, and the buckle cylinder 209 rotates with the shaft column 205 as the axis. The multiple cutting knives 208 all rotate counterclockwise with the shaft column 205 as the axis, and quickly gather toward the center of the first diameter hole 103, and quickly cut the metal wire with their own blades. Due to the coordination of the multiple cutting knives 208, the distance that each cutting knife 208 cuts into the metal wire is not deep, which reduces the wear of the cutting knife 208 and is convenient for the staff to control the cross-section of the metal wire to remain circular. The staff can adjust the output power of the motor according to the different metal materials to make the device automatically adjust the cutting force, so as to improve the yield rate and reduce the production cost.Both ends of the inclined slide 204 are set to be semicircular. In the cutting process of the metal wire drawing device, in order to ensure that the metal wire is cut quickly and accurately, a large cutting force is usually used. This force can cut the metal wire in a short time while ensuring that the cross section is in a perfect circular state. The shaft column 205 is located in the inclined slide 204 and moves rapidly along the inner wall of the inclined slide 204 under the action of the cutting force. This rapid movement enables the cutting knife 208 connected to the shaft column 205 to quickly cut the metal wire. When the shaft column 205 reaches the two ends of the inclined slide 204, it will collide with the inclined slide 204. Collision, this collision is caused by the sudden stop of the shaft column 205 at the end of the inclined slot 204 during high-speed movement. Each collision will cause a certain degree of impact and wear on the shaft column 205 and the inclined slot 204. In the long run, this impact and wear will reduce the service life of the components. The semicircular shape is used to solve this problem. When the shaft column 205 moves to one end of the inclined slot 204, the semicircle and the circle of the shaft column 205 fit closely, which greatly increases the contact area, greatly reduces the pressure on the surfaces of the two, and greatly reduces wear, thereby achieving the effect of increasing the service life of the equipment. The cross-section of the teeth of the first gear 202 is set to a trapezoid. The trapezoid increases the contact area between the teeth of the first gear 202 and the tooth grooves of the second gear 201, reduces the influence of pressure on the two, prevents surface deformation, and increases the service life of the equipment.

[0026] A reserved groove 207 is provided on one side of the extension rod 206. Since the material will produce elastic deformation during extrusion, it is easy to cause the extension rod 206 to collide with the buckle tube 209, thereby scratching and damaging the component. The scratches on the surface will cause the protective layer on the surface of the component to fall off, and air and water vapor will more easily react with the internal materials, resulting in accelerated component damage and reduced equipment life. The reserved groove 207 is used to solve this problem. When the metal wire is cut off, if elastic deformation occurs, the buckle tube 209 can move toward the reserved groove 207. The reserved groove 207 provides enough space, so that even if the metal is deformed, the buckle tube 209 will not collide with the extension rod 206, avoiding hard contact that may cause damage to the equipment, and also ensuring the smooth progress of the truncation process, thereby achieving the effect of increasing the service life of the equipment. The diameter of the reserved groove 207 is larger than the diameter of the buckle tube 209, giving the buckle tube 209 enough anti-collision space to improve the safety of equipment use. The drawing die 101 is fixed with triangular fasteners 3 at both ends, and the back of the triangular fasteners 3 is fixed to the inner wall of the processing equipment 1. The triangular fasteners 3 make the drawing die 101 and the processing equipment 1 present a stable triangular state, thereby improving the stability of the assembly. The front edge of the drawing die 101 is set as a chamfer to reduce the weight of the drawing die 101 near the front side, so that its center of gravity is as close to the equipment as possible to prevent the assembly from falling.

[0027] The working principle of the utility model is as follows: when the staff needs to cut the metal wire, the motor is started, and the motor drives multiple gears to mesh and rotate, so that the second gear 201 meshes and drives the first gear 202 to rotate counterclockwise, so that the inclined slide 204 pushes the shaft column 205 to move toward the end of the inclined slide 204 close to the center of the circle through friction, and at the same time, the buckle cylinder 209 rotates with the shaft column 205 as the axis, and multiple cutting knives 208 all rotate counterclockwise with the shaft column 205 as the axis, and quickly gather to the center of the first diameter hole 103, and quickly cut the metal wire with their own blades. Due to the coordination of multiple cutting knives 208, the distance that each cutting knife 208 cuts into the metal wire is not deep, which reduces the wear of the cutting knife 208. At the same time, it is convenient for the staff to control the cross-section of the metal wire to remain circular, and the staff can adjust the output power of the motor according to the different metal materials to make the device automatically adjust the cutting force.
