Description

Technical Field

[0001] This invention relates to the field of stamping technology, specifically to a cold heading process equipment for metal wire. Background Technology

[0002] Cold heading of metal wire is a precision plastic processing technology that uses a mold to apply pressure to metal wire at room temperature to cause plastic deformation, thereby achieving upsetting, forming, and shaping. It can continuously complete processes such as feeding, cutting, and multi-station extrusion forming, and is suitable for the large-scale manufacturing of fasteners, bushings, and irregularly shaped hardware parts.

[0003] For example, in the cold heading machine for steel ball processing with announcement number CN223543430U, the starting drive component drives the filter plate to reciprocate and oscillate along the box through the transmission mechanism, filtering the material falling on the filter plate, and then letting it fall into the collection box through the first discharge port. The waste liquid falls into the box through the filter plate, realizing the function of rapid filtration and separate storage.

[0004] For example, an automated cold heading machine production line system with announcement number CN204135276U consists of multiple cold heading machines. The basket loading and unloading system includes baskets, trays, robotic arms, robotic arm translation mechanisms, and robotic arm control devices. A weighing mechanism is used to place the baskets. When the weight of the steel balls in the trays reaches a set value, the control device controls the translation mechanism to move the robotic arm to the corresponding cold heading machine. The robotic arm places the full-loaded trays and baskets onto the full-load basket conveyor system, and then grabs empty trays and baskets from the empty basket conveyor system and places them onto the weighing mechanism. Workers only need to place enough empty trays and baskets on the empty basket conveyor system and periodically remove trays and baskets full of steel balls from the full-load basket conveyor system to achieve continuous automated production of the cold heading machine and improve the efficiency of steel ball production.

[0005] Most of the existing technologies mentioned above improve the overall structure. However, when cold heading a single material, there are problems such as discontinuous feeding and low production efficiency, which make it difficult to meet the needs of high-speed, continuous, and precise large-scale production of fasteners and irregularly shaped parts. Therefore, it is necessary to use metal wire continuous cold heading equipment and multi-station forming system. Summary of the Invention

[0006] The purpose of this invention is to provide a cold heading process equipment for metal wire to solve the problems of non-continuous feeding and low production efficiency in cold heading process mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a metal wire cold heading process equipment, comprising a frame, a feeding roller, and a metal wire. The feeding roller is installed inside the frame, and the metal wire is disposed on the feeding roller. A fixing plate is fixedly connected inside the frame, and a straightening cylinder is fixedly connected to the upper surface of the fixing plate. The metal wire passes through the straightening cylinder to the other side of the straightening cylinder. A moving groove is opened inside the frame, and a roller is installed inside the moving groove. A cold heading structure is installed inside the frame, through which the metal wire is continuously cold-headed to form its shape. A cutting structure is installed inside the frame, through which the metal wire can be cut.

[0008] Furthermore, the cold heading structure includes a movable seat, the side of which is movably mounted inside the movable slot. A placement frame is provided on the upper surface of the movable seat, and a fixed column is fixedly connected to the upper surface of the movable seat. A movable column is fixedly connected to the lower surface of the placement frame. The top of the fixed column is located inside the movable column, and a spring is sleeved on the outer side of the movable column.

[0009] Furthermore, a limiting block is fixedly connected to the upper surface of the placement rack, and a lower mold is fixedly connected to the upper surface of the placement rack, with the limiting block located on the right side of the lower mold.

[0010] Furthermore, a second cylinder is fixedly connected to the inner top of the frame, an upper mold is fixedly connected to the bottom of the second cylinder, and a support base is fixedly connected to the inner bottom of the frame, with the support base located directly below the upper mold.

[0011] Furthermore, an air blowing pipe is fixedly connected to the inner top of the frame, and the air blowing pipe is located on the left side of the second cylinder.

[0012] Furthermore, a second motor is fixedly connected to the right side of the frame, and a lead screw is fixedly connected to the output end of the second motor. The movable seat is movably mounted on the lead screw, and a guide rod is fixedly installed inside the movable slot. The guide rod is movably connected to the movable seat.

[0013] Furthermore, the cutting structure includes a first cylinder, which is fixedly installed on the inner top of the frame. A cutting blade is fixedly connected to the bottom of the first cylinder. A cutting base is fixedly connected inside the frame, and the cutting base is located directly below the cutting blade. The metal wire is located between the cutting base and the cutting blade.

[0014] Furthermore, a first motor is fixedly connected to the upper surface of the fixing plate, a rotating wheel is fixedly connected to the output end of the first motor, a support base is fixedly connected to the upper surface of the fixing plate, the metal wire is located inside the support base, and the lower surface of the rotating wheel is in contact with the outer surface of the metal wire inside the support base.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This metal wire cold heading processing equipment, through its cold heading structure, can drive the cut metal wire segments to continuously move along the moving seat to the cold heading position for processing, realizing continuous and uninterrupted cold heading operations, effectively improving overall processing efficiency. Furthermore, the fixed column and the moving column, together with the springs sleeved on the outside, allow the placement frame to fall onto the support base when the upper mold presses down for cold heading. The support base provides support for the placement frame, facilitating the cold heading of the metal wire and preventing excessive cold heading impact from damaging components such as the lead screw and guide rod.

[0016] Furthermore, through the cutting structure, fixed-length cutting can be completed directly after the metal wire is delivered to the designated location, without the need to transfer it to other equipment for cutting and processing. This reduces the time required for process flow and further improves production efficiency, making it suitable for the high-speed, continuous, and precision large-scale production needs of fasteners and irregularly shaped hardware parts.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-8 The present invention provides the following technical solution: a cold heading system for metal wire 3, which solves the problem of cold heading process that cannot be continuously fed and has low production efficiency. It discloses a system including: a frame 1, a feeding roller 2 and a metal wire 3. The feeding roller 2 is installed in the frame 1 and the metal wire 3 is disposed on the feeding roller 2. The feeding roller 2 can rotate in the frame 1 and the metal wire 3 on the feeding roller 2 is released by the rotation.

[0021] A fixing plate 4 is fixedly connected inside the frame 1. A straightening cylinder 5 is fixedly connected to the upper surface of the fixing plate 4. The straightening cylinder 5 is a metal cylinder with a length of 50cm and an inner diameter equal to that of the metal wire 3. The metal wire 3 cannot be bent when passing through the straightening cylinder 5, and is thus straightened. The metal wire 3 passes through the straightening cylinder 5 to the other side of the straightening cylinder 5. A moving groove 12 is opened inside the frame 1. Rollers 17 are installed inside the moving groove 12. The rollers 17 can rotate in the moving groove 12. There are multiple rollers 17. The rollers 17 can assist the moving seat 13 to move. A cold heading structure is installed inside the frame 1. The metal wire 3 is continuously cold-headed to form its shape through the cold heading structure.

[0022] The cold heading structure includes a movable base 13, which is movably mounted on the side inside a movable slot 12. A placement frame 21 is mounted on the upper surface of the movable base 13, and a fixed column 18 is fixedly connected to the upper surface of the movable base 13. A movable column 19 is fixedly connected to the lower surface of the placement frame 21. The top of the fixed column 18 is located inside the movable column 19, and a spring 20 is sleeved on the outer side of the movable column 19. When the placement frame 21 is subjected to downward pressure, the placement frame 21 moves downward and compresses the spring 20. When the pressure on the placement frame 21 is released... Spring 20 returns to its original position by lifting the placement rack 21. A limiting block 22 is fixedly connected to the upper surface of the placement rack 21, and a lower mold 23 is fixedly connected to the upper surface of the placement rack 21. The limiting block 22 is located to the right of the lower mold 23. The metal wire 3 passes through the limiting block 22 and enters the lower mold 23. The limiting block 22 limits the metal wire 3, ensuring it accurately enters the lower mold 23. A second cylinder 24 is fixedly connected to the inner top of the frame 1, and an upper mold 25 is fixedly connected to the bottom of the second cylinder 24. The cylinder 24 and the upper mold 25 form a cold forging structure. Multiple cold forging structures are installed inside the frame 1, enabling multi-round stamping of the metal wire 3, facilitating its forming. During operation, the second cylinder 24 drives the upper mold 25 downwards, thereby stamping the metal wire 3 within the lower mold 23. A support base 26 is fixedly connected to the inner bottom of the frame 1, located directly below the upper mold 25. When the moving seat 13, carrying the placement frame 21, moves below the upper mold 25, the second cylinder 24 drives the upper mold... When 25 moves down, it will apply pressure to the placement rack 21. At this time, the placement rack 21 is pressed down and falls onto the support base 26. The support base 26 provides support force to the placement rack 21 when it is pressed. An air blowing pipe 27 is fixedly connected to the inner top of the frame 1. The air blowing pipe 27 is located to the left of the second cylinder 24. The bottom of the air blowing pipe 27 is inclined, which can provide an inclined airflow. The compressed air blown out through the air blowing pipe 27 can blow the formed metal wire 3 out of the lower mold 23, so that the lower mold 23 can return to its original position for the next processing.

[0023] In practical use, the movable seat 13 moves, thus moving the placement frame 21, until the placement frame 21 is directly below the upper mold 25. At this time, the second cylinder 24 drives the upper mold 25 to move downward, performing cold heading stamping on the metal wire 3 between the upper mold 25 and the lower mold 23. While the upper mold 25 continues to press down, the placement frame 21 drives the movable column 19 to move downward along the fixed column 18, while compressing the spring 20, until the bottom of the placement frame 21 falls on the support base 26, which provides stable support, completing one cold heading stamping operation. After the stamping is completed, the second cylinder 24 drives the upper mold 25 to reset, and the spring 20 rebounds to lift the placement frame 21, so that the placement frame 21 returns to its initial height. Then, the movable seat 13 drives the placement frame 21, which has completed the stamping, to move forward to the next set of cold heading structures, repeating the above stamping process to complete the multi-station cold heading forming operation in sequence. Finally, the air blowing pipe 27 works to blow out the airflow, blowing the formed metal wire 3 out from the lower mold 23.

[0024] Example 2: Please refer to Figures 3-6 Based on Embodiment 1, a cutting structure is also disclosed, the specific structure of which is as follows: A cutting structure is installed inside the frame 1, which can cut the metal wire 3. The cutting structure includes a first cylinder 9, which is fixedly installed on the inner top of the frame 1. A cutting blade 10 is fixedly connected to the bottom of the first cylinder 9. A cutting base 11 is fixedly connected inside the frame 1, and the cutting base 11 is located directly below the cutting blade 10. The metal wire 3 is located between the cutting base 11 and the cutting blade 10. When the first cylinder 9 works, it drives the cutting blade 10 to move downward, cutting the metal wire 3 on the cutting base 11. A first electric... The first motor 6 is a servo motor. The output end of the first motor 6 is fixedly connected to a rotating wheel 7. The outer surface of the rotating wheel 7 is provided with multiple textures to increase friction. The rotating wheel 7 uses friction to drive the metal wire 3 to move. The rotating wheel 7 can be made of rubber. The upper surface of the fixed plate 4 is fixedly connected to a support base 8. The metal wire 3 is located inside the support base 8. The lower surface of the rotating wheel 7 is in contact with the outer surface of the metal wire 3 inside the support base 8. When the first motor 6 works, it drives the rotating wheel 7 to rotate. The rotating wheel 7 drives the metal wire 3 to move through friction, so that the metal wire 3 moves and reaches the lower mold 23. The moving length of the metal wire 3 can be calculated by the number of rotations of the rotating wheel 7.

[0025] In practical use, the metal wire 3 is passed through the straightening cylinder 5 and enters between the rotating wheel 7 and the support base 8. The rotating wheel 7 is driven to rotate by the first motor 6, and the metal wire 3 is pulled forward by friction. The material is continuously fed to the cutting base 11. After the set length of material is fed, the first cylinder 9 drives the cutting blade 10 to move downward and cut the metal wire 3 into blanks of the set length. The cut blanks continue to be conveyed forward into the cold heading station. The moving base 13 drives the placement frame 21 to pass through multiple sets of cold heading processing stations in sequence to complete the multi-station continuous cold heading forming operation.

[0026] Example 3: Please refer to Figure 3 Based on Embodiment 1, a conveying structure is also disclosed, the specific structure of which is as follows: A second motor 14 is fixedly connected to the right side of the frame 1. The second motor 14 is a servo motor. A lead screw 15 is fixedly connected to the output end of the second motor 14. The lead screw 15 is located in the moving groove 12. The end of the lead screw 15 away from the second motor 14 is movably connected to the inner wall of the moving groove 12 through a bearing. The moving groove 12 can protect the lead screw 15 and reduce the impact of dust, debris and other contaminants on the lead screw 15. The moving seat 13 is movably mounted on the lead screw 15. The operation of the second motor 14 drives the lead screw 15 to rotate, thereby driving the moving seat 13 to move. A guide rod 16 is fixedly installed inside the moving groove 12. The guide rod 16 is movably connected to the moving seat 13 and assists the moving seat 13 to move.

[0027] In practical use, the second motor 14 drives the lead screw 15 to rotate. During the rotation of the lead screw 15, the moving seat 13 moves along the guide rod 16 in the moving groove 12, and the moving seat 13 moves through each processing station one by one. With the assistance of the rollers 17 in the moving groove 12, the movement of the moving seat 13 is smoother and more stable. With the help of the servo motor, the stopping position of the moving seat 13 can be precisely controlled to ensure that each cold heading stamping station can be aligned with the corresponding metal wire 3 blank, so as to realize continuous and stable multi-station cold heading processing.
