Technical Field

[0001] The invention relates to the technical field of flat steel wire processing, in particular to a flat steel wire forming die. Background Art

[0002] Flat wire forming is a process of processing round steel wire into a flat shape through specific equipment and technical means. This process is widely used in many industries, such as construction, manufacturing, furniture manufacturing, etc. At the same time, flat wire forming equipment is constantly updated with the development of the times.

[0003] The patent with the patent announcement number CN220862587U discloses a flat steel wire forming die, which relates to the field of flat steel wire processing technology. The flat steel wire forming die includes a shaped plate, a lower die and a width control mechanism. The shaped plate is provided with four groups of rectangularly distributed guide pillars, a hydraulic rod is fixedly installed on the top of the shaped plate, an upper die is provided on the top of the lower die, the lower die and the upper die are located inside the shaped plate, and the width control mechanism is provided on the lower die and the upper die, and the width control mechanism includes movable baffles respectively provided on the lower die and the upper die. The patent facilitates the adjustment of the front and rear positions of the movable baffle, so that the width size of the flat steel wire forming can be controlled according to the needs of the user, avoiding the tediousness of replacing the lower die and the upper die when the production size changes, improving the convenience of use and the scope of application of the die, and the overall disassembly or assembly of the die is relatively convenient, which is convenient for subsequent inspection and maintenance, and improves the practicality of the die.

[0004] However, the device still has shortcomings: the device can control the width of the flat steel wire according to demand, but in the process of making the steel wire into a flat steel wire, during the direct cold extrusion of the steel wire, the stress is relatively concentrated, which easily leads to the risk of cold cracks in the steel wire due to stress during the forming process, which can easily reduce the use strength of the finished flat steel wire to a certain extent. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a flat steel wire forming die, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented by the following technical scheme: a flat steel wire forming die, comprising a device body, wherein a motor is arranged inside the device body, a base is arranged at the bottom of the device body, a heat preservation frame is arranged on the top of the base, an L-shaped plate is arranged on the inner wall of the heat preservation frame, and a receiving roller is arranged on the side of the L-shaped plate away from the device body;

[0007] The front of the device body is provided with an anti-crack device, the side of the anti-crack device away from the receiving roller is provided with an anti-wear device, and the anti-bending device is provided inside the anti-wear device;

[0008] The anti-crack device comprises two fixed circular plates, the backs of the two fixed circular plates are symmetrical and fixedly installed on the front side of the device body, the two fixed circular plates are fixedly installed with circular groove blocks on one side close to the L-shaped plate, an extrusion die is penetrated and slidably installed inside the circular groove blocks, two motors are arranged inside the device body, and threaded rods are fixedly installed on the output ends of the two motors, one end of the threaded rods penetrates and is threadedly connected inside the extrusion die, a heating device is fixedly installed on the front side of the extrusion die, a U-shaped frame is fixedly installed on the top of the inner wall of the insulation frame near one end of the L-shaped plate, an extrusion plate is penetrated and slidably installed inside the U-shaped frame, semicircular blocks are fixedly installed on both sides of the extrusion plate away from the axis of the U-shaped frame, a baffle is fixedly installed on the front side of the heating device, an inclined rod is hinged on the top of the baffle, a connecting rod rubber block is slidably installed on the inner wall of the U-shaped frame, and the bottom of the connecting rod rubber block is hinged to the top of the inclined rod through a torsion spring.

[0009] The U-shaped frame is provided with a sliding groove at one end of the front side, and a longitudinal spring is arranged between the extrusion plate and the U-shaped frame. The baffle plate moves inside and penetrates the outer wall of the threaded rod. The semicircular block of the outer wall of the extrusion plate is located on the bottom movement trajectory of the connecting rod rubber block. The raw material passes through the openings on both sides of the insulation frame from right to left, and at the same time, the raw material passes through the gap of the outer wall of the symmetrically distributed extrusion die, and the left end of the raw material is wound around the outer wall of the receiving roller, and the receiving roller is driven by an external motor to rotate along the outer wall of the L-shaped plate. The receiving roller pulls the raw material to continuously transmit and wind it circle by circle, and the motor is started. The output end of the motor drives the threaded rod to rotate, and the threaded rod drives the threadedly connected extrusion die to slide along its own outer wall away from the device body through the thread groove of its own outer wall. At this time, the outer wall of the extrusion die will extend outward along the inside of the circular groove block, thereby increasing the gap between the extrusion die and the circular groove block, and the fixed circular plate is used to perform rotation of the circular groove block. The U-shaped frame limits the position of the extrusion plate and stabilizes it. At the same time, the heating equipment moves away from the main body of the device, and the heating equipment is started before the processing starts to preheat the extrusion die. At this time, the raw material will be continuously extruded and formed by the extrusion die under the pull of the receiving roller. When the formed flat steel wire is conveyed toward the receiving roller, the top of the flat steel wire will be pressed by the bottom of the extrusion plate, and the guidance of the arc surface at the bottom of the extrusion plate will not hinder the conveying process of the flat steel wire. At this time, the U-shaped frame limits the position of the extrusion plate and stabilizes it. At the same time, the heating equipment moves away from the main body of the device and pushes the baffle to move synchronously. The baffle drives the inclined rod to move synchronously. The hinge shaft at the top of the inclined rod generates a rotational force and pulls the connecting rod rubber block to generate a downward force. At this time, the connecting rod rubber block will press the semicircular blocks on both sides of the extrusion plate when it moves downward along the U-shaped frame, thereby realizing the pressing and limiting of the extrusion plate to ensure its stability.

[0010] According to the above technical solution, the anti-wear device includes an L-shaped telescopic plate, a horizontal plate and a telescopic scraper. The back side of the telescopic end of the L-shaped telescopic plate is fixedly installed on the front side of the device body, the horizontal plate is fixedly installed on the fixed end of the L-shaped telescopic plate close to the circular groove block, and the arc surface of the outer wall of the fixed end of the telescopic scraper is fixedly installed on the side of the horizontal plate close to the circular groove block.

[0011] According to the above technical solution, the fixed end of the L-shaped telescopic plate is fixedly installed at the front edge of the baffle plate close to one side of the device body, and the telescopic scraper blade is in contact with the outer wall of the extrusion die away from the horizontal plate. When the baffle plate moves away from the device body, it drives the fixed end of the L-shaped telescopic plate to move synchronously. At this time, the device body limits the telescopic end of the L-shaped telescopic plate to cause the telescopic end of the L-shaped telescopic plate to extend synchronously, the L-shaped telescopic plate drives the horizontal plate to move synchronously, and the horizontal plate drives the telescopic scraper blade to move synchronously, thereby ensuring that the concave outer wall of the telescopic scraper blade is always in close contact with the outer wall of the extrusion die, and the extrusion die will rotate along the inside of the circular groove block under the influence of the friction force generated when the raw material passes through.

[0012] According to the above technical scheme, the anti-wear device also includes a screw, an interference flow plate and an L-shaped tough plate. One end of the back side of the screw is rotatably installed on the front side of the device body. The outer wall of the front end of the screw is penetrated and threadedly connected to the inside of the cross plate. Several spoilers are equidistant and fixedly installed on the outer wall of one end of the back of the screw. The front side of the L-shaped tough plate is fixedly installed on the back side of the circular groove block. The arc surface of the outer wall of the L-shaped tough plate is located on the movement trajectory of the spoiler. When the cross plate moves away from the device body, it will drive the threaded screw to generate a rotational force. When the screw rotates along the front side of the device body, it drives the spoiler to rotate synchronously. During the rotation of the spoiler, it will resist the arc surface of the L-shaped tough plate, causing the L-shaped tough plate to bend and deform at the resisted end. Under the guidance of the arc surface of the L-shaped tough plate and when its bending deformation reaches a certain amplitude, the spoiler is caused to pass over the L-shaped tough plate. When the L-shaped tough plate is reset by its own toughness, it will continue to swing to generate vibration, and the extrusion mold is caused to vibrate through the transmission of force.

[0013] According to the above technical scheme, the anti-bending device includes a transmission belt, a rotating rod, a plurality of U-shaped telescopic plates and a plurality of resistance rollers. The top of the inner wall of the transmission belt is transmission-installed on the outer wall of one end of the front side of the screw rod, and the back end of the rotating rod is rotatably installed on the front side of the device body. The fixed ends of the plurality of U-shaped telescopic plates are equidistant and fixedly installed on the outer wall surface of the rotating rod, and the two ends of the plurality of resistance rollers are fixedly installed inside the U-shaped groove of the telescopic end of the U-shaped telescopic plate.

[0014] The U-shaped extension plate has a U-shaped groove inside, and a spring is arranged inside. The screw drives the rotating rod to rotate along the front of the device body through the transmission belt, and the rotating rod drives the U-shaped extension plate to rotate. When the rotating rod rotates, the preparatory work before processing is carried out. Through the heat radiation of the heating equipment and the initial rotation of the rotating rod, the lubricating oil between the rotating rod and the inside of the device body can be fully infiltrated, thereby reducing the stagnation feeling of the rotating rod during the later rotation. When the raw material passes through the bottom of the resistance roller, friction force will be generated to prompt the resistance roller to generate a rotation force. At this time, the resistance roller prompts the rotating rod to realize gradual and uninterrupted rotation.

[0015] According to the above technical scheme, the anti-bending device also includes a protrusion, a telescopic brush plate and a semicircular ring. The protrusion is fixedly installed inside and on the outer wall of one end of the back side of the rotating rod. The back side of the fixed end of the telescopic brush plate is slidably installed on the front side of the device body through a spring. The semicircular ring is fixedly installed on the fixed end of the telescopic brush plate. The arc surface of the outer wall of the semicircular ring is located on the movement trajectory of the protrusion. When the rotating rod rotates, the protrusion is driven to rotate. When the protrusion rotates, it is separated from the resistance to the semicircular ring. At this time, the telescopic brush plate slides to the left along the front side of the device body under the elastic force of the spring, and the semicircular ring is always close to the outer wall of the protrusion under the elastic force of the spring. When the protrusion revolves one circle, the telescopic brush plate is synchronously reset. This reciprocating motion enables the telescopic brush plate to slide back and forth left and right along the outer wall of the raw material, and the telescopic end of the telescopic brush plate can adapt to raw materials of different thicknesses.

[0016] The present invention provides a flat steel wire forming die, which has the following beneficial effects:

[0017] (1) The present invention realizes free adjustment of the raw material forming width by setting an anti-crack device through the coordination of fixed circular plates, circular groove blocks, extrusion molds, threaded rods, heating equipment, U-shaped frames, extrusion plates, baffles, inclined rods and connecting rod rubber blocks, thereby eliminating the tedious steps brought by replacing parts, thereby improving the practicability of the equipment and the forming efficiency of the flat steel wire. At the same time, the heating equipment is used to preheat the extrusion mold to prevent the raw material from being directly cold-started and extruded, which causes stress concentration, and prevents cold cracks from being generated on the surface of the formed flat steel wire, thereby reducing the strength of use; and the connecting rod rubber block is used to press the extrusion plate to prevent shaking due to equipment movement or external force interference, and as the width of the flat steel wire continues to increase, the limiting pressing force on the extrusion plate gradually increases, ensuring that the extrusion plate can always apply stable downward pressure to the flat steel wire, so that the flat steel wire can be close to the outer wall of the receiving roller during the winding process, thereby ensuring the tightness of the receiving winding.

[0018] (2) The present invention sets an anti-wear device, and cooperates with a baffle, an L-shaped telescopic plate, a horizontal plate, a telescopic scraper, a screw, a spoiler and an L-shaped tough plate to cause the telescopic scraper to continuously scrape the outer wall of the extrusion die when the extrusion die rotates, thereby improving the cleanliness of the outer wall where the extrusion die and the raw material are in contact, preventing the extrusion die from causing certain dents and wear when extruding the raw material due to particulate impurities attached to the outer wall, thereby avoiding the reduction of the finished product quality of the flat steel wire; at the same time, relying on the rotation of the spoiler, the heat generated by the heating equipment is evenly diffused during the process of adjusting the extrusion width of the extrusion die, thereby improving the overall heating rate within the processing range, and relying on the vibration force to reduce the blockage feeling of the extrusion die when it expands and contracts inside the circular groove block, and at the same time reducing the adhesion strength of the attachment to the outer wall of the extrusion die.

[0019] (3) The present invention adopts the setting of the anti-bending device, and cooperates with the screw, transmission belt, rotating rod, U-shaped telescopic plate, resistance roller, protrusion, telescopic brush plate and semicircular ring. The resistance roller continuously rotates and squeezes the raw material, so as to ensure that the upper and lower bent or crooked parts of the raw material can be squeezed and straightened by the resistance roller before contacting the extrusion die, thereby reducing the processing difficulty of the raw material and avoiding the uneven overall forming width of the bent part of the raw material due to uneven force during the processing; and the telescopic brush plate continuously brushes away the dirt or impurities attached to the surface of the raw material, so as to prevent the dirt from being attached to the outer wall of the raw material and being deeply embedded in the raw material under the extrusion of the extrusion die and being difficult to remove, and at the same time, prevent the dirt from being pushed to rub the surface of the raw material and leaving scratches in the process of the resistance roller straightening the raw material.

At the same time, the heating device 45 is used to preheat the extrusion die 43 to prevent the raw material from being directly cold-started and extruded, resulting in stress concentration, and to prevent cold cracks from occurring on the surface of the formed flat steel wire, thereby reducing the use strength; through the above cooperation, the pressing of the connecting rod rubber block 410 is used to prevent the extrusion plate 47 from shaking due to equipment movement or external force interference, and as the width of the flat steel wire continues to increase, the limiting pressing force on the extrusion plate 47 gradually increases, ensuring that the extrusion plate 47 can always apply stable downward pressure to the flat steel wire, so that the flat steel wire can be close to the outer wall of the receiving roller 31 during the winding process, thereby ensuring the tightness of the receiving winding.

[0034] When in use, the raw material is passed from right to left through the openings on both sides of the heat preservation frame 21, and at the same time, the raw material is passed through the gaps in the outer walls of the symmetrically distributed extrusion mold 43, and the left end of the raw material is wound around the outer wall of the receiving roller 31, and the receiving roller 31 is driven by an external motor to rotate along the outer wall of the L-shaped plate 3, and the receiving roller 31 pulls the raw material to continuously transmit and wind it circle by circle, and the motor is started, and the output end of the motor drives the threaded rod 44 to rotate, and the threaded rod 44 drives the threadedly connected extrusion mold 43 to slide along its own outer wall in a direction away from the device body 1 through the thread groove on its own outer wall, and at this time, the outer wall of the extrusion mold 43 will extend outward along the inside of the circular groove block 42, thereby increasing The gap between the extrusion die 43 and the circular groove block 42 is set, and the circular plate 41 is fixed to limit the circular groove block 42 so that it will not move.

[0035] See also Figure 1 - Figure 8 On the basis of the above embodiment, another embodiment of the present invention further includes anti-wear devices 5 corresponding in number to and working in coordination with the extrusion dies 43;

[0036] The anti-wear device 5 includes an L-shaped telescopic plate 51, a horizontal plate 52 and a telescopic scraper 53. The back side of the telescopic end of the L-shaped telescopic plate 51 is fixedly installed on the front side of the device body 1, the horizontal plate 52 is fixedly installed on the fixed end of the L-shaped telescopic plate 51 close to the circular groove block 42, and the arc surface of the outer wall of the fixed end of the telescopic scraper 53 is fixedly installed on the side of the horizontal plate 52 close to the circular groove block 42.

[0037] The fixed end of the L-shaped telescopic plate 51 is fixedly installed on the front edge of the baffle 48 close to the side of the device body 1, and the telescopic scraper 53 is in contact with the outer wall of the extrusion mold 43 away from the side of the horizontal plate 52. Through the above cooperation, the telescopic scraper 53 is prompted to continuously scrape the outer wall of the extrusion mold 43 when the extrusion mold 43 rotates, thereby improving the cleanliness of the outer wall in contact with the raw material of the extrusion mold 43, preventing the extrusion mold 43 from causing certain dents and wear when extruding the raw material due to particulate impurities attached to the outer wall, thereby avoiding the reduction of the finished product quality of the flat steel wire.

[0038] The anti-wear device 5 also includes a screw 54, an anti-flow plate 55 and an L-shaped tough plate 56. The back end of the screw 54 is rotatably installed on the front of the device body 1. The outer wall of the front end of the screw 54 is penetrated and threadedly connected to the inside of the cross plate 52. The anti-flow plates 55 are equidistant and fixedly installed on the outer wall of the back end of the screw 54. The front of the L-shaped tough plate 56 is fixedly installed on the back of the circular groove block 42. The arc surface of the outer wall of the L-shaped tough plate 56 is located on the movement trajectory of the spoiler 55. Through the above cooperation and relying on the rotation of the spoiler 55, the heat generated by the heating device 45 is evenly diffused during the process of the extrusion die 43 adjusting the extrusion width, thereby improving the overall heating rate within the processing range. At the same time, the vibration force is relied on to reduce the blockage of the extrusion die 43 when it expands and contracts inside the circular groove block 42, and at the same time, the adhesion strength of the attachment to the outer wall of the extrusion die 43 is reduced.

[0039] When in use, the baffle plate 48 moves in the direction away from the device body 1, driving the fixed end of the L-shaped telescopic plate 51 to move synchronously. At this time, the device body 1 limits the telescopic end of the L-shaped telescopic plate 51 to cause the telescopic end of the L-shaped telescopic plate 51 to extend synchronously, and the L-shaped telescopic plate 51 drives the horizontal plate 52 to move synchronously, and the horizontal plate 52 drives the telescopic scraper 53 to move synchronously, thereby ensuring that the concave outer wall of the telescopic scraper 53 is always in close contact with the outer wall of the extrusion mold 43, and the extrusion mold 43 will rotate along the inside of the circular groove block 42 under the influence of the friction force generated when the raw material passes through.

When the screw rod 54 rotates along the front side of the device body 1, it will drive the spoiler 55 to rotate synchronously. During the rotation of the spoiler 55, it will resist the arc surface of the L-shaped tough plate 56, causing the L-shaped tough plate 56 to bend at the resisted end. Under the guidance of the arc surface of the L-shaped tough plate 56 and when its bending deformation reaches a certain amplitude, the spoiler 55 is caused to pass over the L-shaped tough plate 56. When the L-shaped tough plate 56 is reset by its own toughness, it will continue to swing to generate vibration, and the extrusion die 43 is caused to vibrate through the transmission of force. Through the above cooperation, relying on the rotation of the spoiler plate 55, the heat generated by the heating device 45 is caused to be evenly diffused during the process of adjusting the extrusion width of the extrusion die 43, thereby improving the overall heating rate within the processing range. At the same time, relying on the vibration force, the blockage feeling of the extrusion die 43 when expanding and contracting inside the circular groove block 42 is reduced, and the adhesion strength of the attachment to the outer wall of the extrusion die 43 is reduced.

The fixed ends of the plurality of U-shaped telescopic plates 63 are equidistant and fixedly mounted on the outer wall surface of the rotating rod 62, and both ends of the plurality of resistance rollers 64 are fixedly mounted inside the U-shaped groove of the telescopic end of the U-shaped telescopic plate 63.

[0042] The outer wall of one end of the front side of the rotating rod 62 is installed on the bottom of the inner wall of the transmission belt 61. A U-shaped groove is opened inside the telescopic end of the U-shaped telescopic plates 63. Springs are arranged inside the U-shaped telescopic plates 63. Through the above cooperation, the resistance roller 64 continuously rotates and extrude the raw material, ensuring that the upper and lower bent or crooked parts of the raw material can be squeezed and straightened by the resistance roller 64 before contacting the extrusion mold 43, reducing the processing difficulty of the raw material and avoiding the uneven overall forming width due to uneven force on the bent part of the raw material during the processing.

The semicircular ring 67 is fixedly installed on the fixed end of the telescopic brush plate 66. The arc surface of the outer wall of the semicircular ring 67 is located on the movement trajectory of the protrusion 65. Through the above cooperation, the telescopic brush plate 66 is used to continuously brush away dirt or impurities attached to the surface of the raw material to prevent dirt from being attached to the outer wall of the raw material and being deeply embedded in the raw material under the extrusion of the extrusion die 43 and difficult to remove. At the same time, it is prevented that the dirt is pushed to rub the surface of the raw material and leave scratches during the process of straightening the raw material by the resistance roller 64.

[0044] During use, the screw rod 54 drives the rotating rod 62 to rotate along the front of the device body 1 through the transmission belt 61, and the rotating rod 62 drives the U-shaped telescopic plate 63 to rotate. The rotating rod 62 performs preparation work before processing while rotating. The heat radiation of the heating device 45 and the initial rotation of the rotating rod 62 enable the lubricating oil between the rotating rod 62 and the inside of the device body 1 to be fully infiltrated, thereby reducing the sense of stagnation when the rotating rod 62 rotates later. When the raw material passes through the bottom of the resistance roller 64, friction will be generated to cause the resistance roller 64 to generate a rotation force. At this time, the resistance roller 64 causes the rotating rod 62 to realize gradual and uninterrupted rotation. Through the above cooperation, the resistance roller 64 continuously rotates and extrude the raw material, ensuring that the upper and lower bent or crooked parts of the raw material can be squeezed and straightened by the resistance roller 64 before contacting the extrusion die 43, thereby reducing the difficulty of processing the raw material and avoiding the bent parts of the raw material during processing. The uneven force during the process causes the overall forming width to be uneven; when the rotating rod 62 rotates, it drives the protrusion 65 to rotate, and when the protrusion 65 rotates, it breaks away from the resistance to the semicircular ring 67. At this time, the telescopic brush plate 66 slides to the left along the front of the device body 1 under the elastic force of the spring, and the semicircular ring 67 is always close to the outer wall of the protrusion 65 under the elastic force of the spring. When the protrusion 65 revolves one circle, the telescopic brush plate 66 is reset synchronously, and the reciprocating movement of the telescopic brush plate 66 enables it to slide back and forth along the outer wall of the raw material, and the telescopic end of the telescopic brush plate 66 can adapt to raw materials of different thicknesses. Through the above cooperation, the telescopic brush plate 66 continuously brushes away dirt or impurities attached to the surface of the raw material, prevents dirt from being attached to the outer wall of the raw material and being deeply embedded in the raw material under the extrusion of the extrusion die 43 and difficult to remove, and at the same time prevents the dirt from rubbing against the surface of the raw material and leaving scratches during the process of straightening the raw material by the conflict roller 64.
