Description

Technical Field

[0001] This application relates to the technical field of flexible wire processing, and in particular to a punching production line and punching method for flexible wire. Background Technology

[0002] In the production of some products, perforated elastic threads are required, such as the tendon thread used in summer mats. Currently, punching equipment is mainly used to process these threads. However, when punching threads, friction exists between the punch and the hole wall when the punch enters the thread and when it is pulled out after punching. Because elastic threads like tendon thread have high elasticity, they are prone to deformation. Furthermore, the friction between the hole wall and the punch is greater in elastic threads compared to less elastic threads, which can easily cause the elastic thread to shift. This results in spacing errors and misalignment of the holes processed on the elastic thread.

[0003] Therefore, regarding the aforementioned related technologies, the inventors believe that existing punching equipment has the problem of poor processing accuracy for processing elastic wires. Summary of the Invention

[0004] To improve the accuracy of punching elastic wires, this application provides a punching production line and punching method for elastic wires.

[0005] The first objective of this invention is achieved by the following technical solution:

[0006] A punching production line for elastic wire includes a feeding device for supplying raw wire, a punching device for punching holes in the wire, a traction mechanism, and a receiving device for collecting finished wire products. The punching device is disposed between the feeding device and the receiving device. The traction mechanism is disposed at the discharge end of the punching device. The traction mechanism includes two wire positioning components for clamping the wire, a wire transfer component for clamping the wire, and a transfer drive component. The two wire positioning components are fixed relative to the punching device. The wire transfer component is disposed between the two wire positioning components. The transfer drive component drives the wire transfer component to reciprocate between the two wire positioning components along the length of the wire.

[0007] By adopting the above technical solution, the punching production line for elastic wire includes a feeding device, a punching device, a traction mechanism, and a receiving device. The feeding device is used to place the raw material rolls of elastic wire and supply the raw material to be processed. The punching device is used to process the raw material to obtain the finished wire. The traction mechanism is located at the discharge end of the punching device, and includes two wire positioning components and a wire transfer component. Both the wire positioning components and the wire transfer component have the function of clamping and fixing the wire. When the punching device punches the wire, the wire positioning components clamp and fix the wire to reduce damage to the wire. The deformation of the wire during punching improves the punching accuracy. After the punching is completed, the wire transfer assembly clamps and fixes the wire. Then, the wire positioning assembly stops clamping and fixing the wire, and the transfer drive assembly drives the wire transfer assembly to pull the processed section of the wire out from the punching equipment's discharge end, while the unprocessed section enters from the punching equipment's feed end. The traction mechanism pulls the wire, which helps improve the consistency of the wire displacement distance during each punching operation, thereby reducing hole position errors and improving the punching accuracy of elastic wire. The receiving equipment is used to collect the finished wire.

[0008] In a preferred embodiment of this application: the wire positioning assembly includes an upper clamping plate, a lower clamping plate, and a clamping plate driving member for driving the upper clamping plate to move toward and away from the lower clamping plate. The lower clamping plate has a limiting through groove for limiting the wire. The side of the upper clamping plate near the lower clamping plate is provided with a plurality of pins for inserting into the holes on the finished wire.

[0009] By adopting the above technical solution, after the elastic wire is punched, the finished wire has holes formed by the punching process; the wire positioning assembly includes an upper clamping plate, a lower clamping plate, and a clamping plate driving component. The clamping plate driving component is used to drive the separation and closure between the upper clamping plate and the lower clamping plate. The lower clamping plate has a limiting through groove to accommodate the elastic wire and limit its movement. The upper clamping plate is provided with pins to insert into the holes on the finished wire, so as to improve the clamping and fixing effect of the wire positioning assembly on the elastic wire, thereby further improving the accuracy of the punching process of the elastic wire.

[0010] In a preferred embodiment of this application: the punching production line further includes a buffer mechanism, the buffer mechanism including a buffer frame, a movable pulley component, a pulley guide rod component, a high-position sensor and a low-position sensor for detecting the position of the movable pulley component, the pulley guide rod component being fixedly connected to the buffer frame, the movable pulley component being slidably connected to the pulley guide rod component, and the high-position sensor and the low-position sensor being fixedly connected to the buffer frame.

[0011] By adopting the above technical solution, the punching production line also includes a buffer mechanism. The buffer frame is used to support and fix the pulley guide rod. The movable pulley is slidably connected to the pulley guide rod and is used to tension the elastic wire by its own weight. The high-position sensor and the low-position sensor are fixedly connected to the buffer frame to detect the position of the movable pulley and determine whether the movable pulley exceeds the maximum and minimum limits. This detects whether there is an imbalance between the feeding speed of the feeding device and the receiving speed of the receiving device, thereby improving the scientific nature of the feeding speed and receiving speed control.

[0015] The first execution module is electrically connected to the first switch module to trigger the first execution signal when it receives the first switch signal;

[0016] The high-position detection module is used to detect the position of the movable pulley component, so as to send a low-position detection signal when the movable pulley component reaches the highest limit of the buffer frame;

[0017] The second switch module is electrically connected to the high-level detection module to issue a second switch signal when a high-level detection signal is received.

[0018] The second execution module is electrically connected to the second switch module to trigger the second execution signal when a second switch signal is received.

[0019] By adopting the above technical solution, the low-position sensor includes a first normally open switch S1, and the high-position sensor includes a second normally open switch S2. When the low-position sensor detects the moving pulley, it closes the first normally open switch S1 to send a low-position detection signal, which triggers the first switch module to send a first switch signal, and then triggers the first execution module to send a first execution signal, used to adjust the feeding speed of the feeding device or the receiving speed of the receiving device. When the high-position sensor detects the moving pulley, it closes the second normally open switch S2 to send a high-position detection signal, which triggers the second switch module to send a second switch signal, and then triggers the second execution module to send a second execution signal, used to adjust the feeding speed of the feeding device or the receiving speed of the receiving device, thereby improving the automation level of feeding speed and receiving speed control.

[0039] 1. A punching production line for elastic wire includes a feeding device, a punching device, a traction mechanism, and a take-up device. The feeding device is used to place the raw material rolls of elastic wire and supply the raw material to be processed. The punching device is used to process the raw material to obtain the finished wire. The traction mechanism is located at the discharge end of the punching device, and includes two wire positioning components and a wire transfer component. Both the wire positioning components and the wire transfer component have the function of clamping and fixing the wire. When the punching device punches the wire, the wire positioning components clamp and fix the wire to reduce the impact of punching. The deformation of the wire during operation improves the accuracy of wire punching. After the punching equipment completes the process, the wire transfer component clamps and fixes the wire. Then, the wire positioning component stops clamping and fixing the wire, and the transfer drive component drives the wire transfer component to pull the processed section of the wire out from the discharge end of the punching equipment, while the unprocessed section enters from the feed end of the punching equipment. By pulling the wire through the traction mechanism, the consistency of the wire displacement distance during each punching process is improved, thereby reducing hole position errors and improving the accuracy of punching elastic wire. The receiving equipment is used to collect the finished wire.

[0040] 2. After the elastic wire is punched, the finished wire has holes formed by the punching process. The wire positioning assembly includes an upper clamping plate, a lower clamping plate, and a clamping plate driving component. The clamping plate driving component is used to drive the separation and closure between the upper clamping plate and the lower clamping plate. The lower clamping plate has a limiting through groove to accommodate the elastic wire and limit its movement. The upper clamping plate is provided with pins to insert into the holes on the finished wire, so as to improve the clamping and fixing effect of the wire positioning assembly on the elastic wire, thereby further improving the accuracy of the punching process of the elastic wire.

[0041] 3. The punching production line also includes a buffer mechanism. The buffer frame is used to support and fix the pulley guide rod. The movable pulley is slidably connected to the pulley guide rod and is used to tension the elastic wire by its own weight. High-position sensors and low-position sensors are fixedly connected to the buffer frame to detect the position of the movable pulley to determine whether the movable pulley exceeds the maximum and minimum limits. This detects whether there is an imbalance between the feeding speed of the feeding equipment and the receiving speed of the receiving equipment, thereby improving the scientific control of the feeding and receiving speeds.

[0057] The following is in conjunction with the appendix Figures 1 to 13 This application will be described in further detail.

[0058] Example 1

[0059] Reference Figure 1 and Figure 2This application discloses a punching production line for elastic wire 100, including a feeding device 1, a punching device 2, a traction mechanism 3, and a receiving device 4. This punching production line can also be used to produce other wires with poor elasticity. This embodiment takes the production of perforated elastic wire as an example for explanation. The feeding device 1 is used to place the raw material roll of elastic wire 100 and supply the raw material of elastic wire 100 to be processed. The punching device 2 is used to process the raw material of the wire to obtain the finished elastic wire 100. The traction mechanism 3 is used to clamp and fix the elastic wire 100 or to pull the elastic wire 100 according to the working state of the punching device 2. The receiving device 4 is used to collect the finished elastic wire 100 after punching.

[0060] The elastic wire 100 raw material refers to the elastic wire 100 segment that has not yet undergone punching processing, while the elastic wire 100 finished product refers to the elastic wire 100 segment that has completed punching processing. During the punching process, a roll of elastic wire 100 can simultaneously include segments of the elastic wire 100 raw material and segments of the elastic wire 100 finished product. The feed end of each piece of equipment / mechanism / component refers to the end into which the elastic wire 100 passes, and the discharge end refers to the end out which the elastic wire 100 passes.

[0061] The feeding device 1 includes at least a feeding rack 41, a wire organizer 6, and a winding roll 10 for winding the elastic wire 100 raw material. The feeding rack 41 is used to support and install the wire organizer 6 and the winding roll 10. The winding roll 10 for winding the elastic wire 100 raw material is located on the side of the feeding rack 41 away from the punching device 2, and the wire organizer 6 is located on the side of the feeding rack 41 close to the punching device 2. Preferably, the feeding rack 41 has multiple layers, and each layer can hold the winding roll 10 and the wire organizer 6. In this embodiment, only one winding roll 10 is placed on each layer. In other embodiments of this application, each layer of the feeding rack 41 can also place multiple winding rolls 10 side by side, which facilitates the simultaneous punching of the elastic wire 100 raw material on multiple winding rolls 10 on the same layer. In this embodiment, the winding coil 10 of the unloading device 1 is not connected to a drive device for controlling the rotation of the winding coil 10, and a traction force needs to be applied to the elastic wire 100 raw material to achieve the unloading function; in other embodiments of this application, the unloading device 1 may also be provided with a drive device for driving the winding coil 10 in the direction.

[0062] Reference Figure 1 and Figure 3The wire organizer 6 includes a roller section 61, a pressure roller section 62, and a pressure roller adjustment assembly 63. The roller section 61 is rotatably connected to two wire-supporting rollers 611, which are used to support the elastic wire 100 to reduce the possibility of damage caused by friction between the elastic wire 100 and the machine frame, housing, etc. A combing plate 612 is fixedly connected to both the feed and discharge sides of the roller section 61. The combing plate 612 has several combing holes 613. The number of combing holes 613 can be determined according to the number of elastic wires 100 that the punching equipment 2 can punch simultaneously. The combing plate 612 is used to separate different elastic wires 100 when the punching production line is used to punch multiple elastic wires 100 simultaneously, to prevent them from tangling. The pressure roller section 62 is slidably connected to the roller section 61. 2. A pressure roller adjustment assembly 63 is connected to adjust the distance between the pressure roller section 62 and the support roller section 61. The pressure roller section 62 is rotatably connected to a pressure roller 621. The surfaces of both the support roller 611 and the pressure roller 621 are covered with soft material to reduce damage to the elastic wire 100. The pressure roller 621 and the support roller 611 cooperate with each other to apply a pressing force to the elastic wire 100, increasing the traction force required when pulling the elastic wire 100, making it easier to keep the elastic wire 100 in a taut state and reducing the possibility of the elastic wire 100 loosening. Preferably, the shape of the comb hole 613 can be a contour hole of the wire to be processed or an elongated hole, which can be selected according to the direction of the elastic wire 100 before passing through the comb hole 613 and the requirement for directional control of the elastic wire 100 after passing through the comb hole 613.

[0063] Reference Figure 4 and Figure 5 In this embodiment, the punching production line also includes a buffer mechanism 5.

Preferably, a buffer mechanism 5 is provided between the feeding device 1 and the punching device 2, and a buffer mechanism 5 is provided between the punching device 2 and the receiving device 4. A wire guide 6 can be added to the side of the buffer frame 51 near the feeding device 1 according to actual needs. A wire guide 6 can also be added to the side of the buffer frame 51 near the punching device 2 according to actual needs. Whether to use a wire guide 6 in the buffer mechanism 5 should be determined based on whether the elastic wire 100 may come into contact with the equipment frame or housing, and whether there is a risk of the elastic wire 100 getting tangled together.

[0064] The elastic wire 100 is drawn out from the winding coil 10, passes through the wire organizer 6, and enters the buffer mechanism 5. The buffer mechanism 5 includes a buffer frame 51, a movable pulley 52, a pulley guide rod 53, a high-position sensor 54, and a low-position sensor 55. The pulley guide rod 53 is fixedly connected to the buffer frame 51 and is vertically arranged. The buffer frame 51 is used to support and fix the pulley guide rod 53. The movable pulley 52 is slidably connected to the pulley guide rod 53. In this embodiment, the pulley guide rod 53 includes multiple guide rods, and the movable pulley 52 is provided with several pulleys. The elastic wire 100 contacts the... The bottom of the movable pulley component 52 is used to tension the elastic wire 100 by its own weight. The high position sensor 54 is fixedly connected to the top of the buffer frame 51, and the low position sensor 55 is fixedly connected to the bottom of the buffer frame 51. The high position sensor 54 and the low position sensor 55 are used to detect the position of the movable pulley component 52 to determine whether the movable pulley component 52 exceeds the maximum and minimum limits, thereby detecting whether there is an imbalance between the feeding speed of the feeding device 1 and the receiving speed of the receiving device 4, so as to improve the scientific nature of the feeding speed and receiving speed control.

The die guide 9 is provided with a comb plate 612, a guide roller 91, a guide plate 92, and another guide roller 91 in sequence from the feed end to the discharge end. The surface of the guide roller 91 is covered with a soft material, and the surface of the guide roller 91 is provided with a first guide groove 911. The upper surface of the guide plate 92 is provided with a second guide groove 912. The die guide 9 is used to adjust the direction of the elastic wire 100 before it enters the punching equipment 2, so that the elastic wire 100 remains straight in the die used by the punching equipment 2, thereby improving the accuracy of punching the elastic wire 100.

[0066] Reference Figure 1 and Figure 7 The punching equipment 2 includes a punching machine 21 and a punching die 22. The punching machine 21 is provided with an output shaft 212. The punching die 22 includes an upper template 221 and a lower template 222. The upper template 221 is vertically slidably connected to the lower template 222. The output shaft 212 is fixedly connected to the upper template 221. The output shaft 212 is used to drive the punching die 22 to close and open, thereby punching the elastic wire 100. In this embodiment, the punching machine 21 is a servo punch press.

[0067] Reference Figure 7 and Figure 8The lower template 222 is fixedly connected to the punching machine 21. The lower template 222 is provided with a punching groove 223 for accommodating and positioning the elastic wire 100. Several punching holes are opened in the punching groove 223, which penetrate the lower template 222. The punching holes are evenly spaced. The upper template 221 is provided with several punches that correspond one-to-one with the punching holes.

[0068] Reference Figure 8 and Figure 9 Several elastic push rods 224 of the same specification are symmetrically arranged on both sides of the punched groove 223 so that the elastic push rods 224 on both sides of the punched groove 223 apply the same force to the elastic wire 100, so as to center the elastic wire 100 and reduce the possibility of hole displacement when punching the elastic wire 100.

[0069] The side wall of the punching groove 223 is provided with a plurality of push rod holes 223a for accommodating elastic push rods 224. The elastic push rod 224 includes a rod body 224a and an elastic element 224b. One end of the elastic element 224b is fixedly connected to the push rod hole 223a, and the other end of the elastic element 224b is fixedly connected to the rod body 224a. The elastic element 224b is used to apply a force toward the opposite side of the punching groove 223 to the rod body 224a. The end of the rod body 224a near the opposite side of the punching groove 223 is provided with a rounded corner so as to guide the elastic wire 100 when it enters the punching die 22, and at the same time reduce the damage of the rod body 224a to the elastic wire 100.

[0070] Reference Figure 10 and Figure 11The traction mechanism 3 is located at the discharge end of the punching die 22. The traction mechanism 3 includes two wire positioning components 31 for clamping the elastic wire 100, a wire transfer component 32 for clamping the elastic wire 100, and a transfer drive component 33. The two wire positioning components 31 are fixed relative to the punching device 2 and are located on the feed side and discharge side of the traction mechanism 3, respectively. The wire transfer component 32 is positioned between the two wire positioning components 31. The transfer drive component 33 drives the wire transfer component 32 to reciprocate along the length of the wire between the two wire positioning components 31. In this embodiment, the transfer drive component 33 is a lead screw drive component. The operating principle of the traction mechanism 3 is as follows: When the punching equipment 2 punches the wire, the wire positioning component 31 clamps and fixes the wire to reduce the deformation of the wire during punching and improve the punching accuracy. After the punching equipment 2 finishes processing, the wire transfer component 32 clamps and fixes the wire. Then, the wire positioning component 31 stops clamping and fixing the wire, and the transfer drive component 33 drives the wire transfer component 32, so that the wire transfer component 32 pulls the processed section of the wire out from the discharge end of the punching equipment 2, and the unprocessed section enters from the feed end of the punching equipment 2. The wire is pulled by the traction mechanism 3, which helps to improve the consistency of the wire displacement distance during each punching process, thereby reducing the hole position error and improving the punching accuracy of the elastic wire 100.

[0071] After the elastic wire 100 is punched, the finished wire has holes formed by the punching process; the wire positioning assembly 31 includes an upper clamping plate 311, a lower clamping plate 312, and a clamping plate driving component 313. The lower clamping plate 312 has a limiting through groove 314 on the side near the upper clamping plate 311 for limiting the elastic wire 100, for accommodating the elastic wire 100, and limiting the elastic wire 100; the upper clamping plate 311 has a... There are several pins 315 for inserting into the holes on the finished elastic wire 100 to improve the clamping and fixing effect of the wire positioning assembly 31 on the elastic wire 100. The upper clamping plate 311 is vertically slidably connected to the lower clamping plate 312. The clamping plate driving member 313 is used to drive the upper clamping plate 311 to move towards and away from the lower clamping plate 312, thereby realizing the separation and closing between the upper clamping plate 311 and the lower clamping plate 312. Preferably, the clamping plate driving member 313 is a cylinder.

[0072] In this embodiment, the wire transfer assembly 32 also includes an upper clamping plate 311, a lower clamping plate 312 and a clamping plate driving member 313, and the pins 315 on the upper clamping plate 311 and the limiting through grooves 314 on the lower clamping plate 312 of the wire transfer assembly 32 are consistent with the wire positioning assembly 31.

[0073] In this embodiment, after the elastic wire 100 is led out from the discharge end of the traction mechanism 3, it passes through a buffer mechanism 5 and is then introduced into the receiving device 4, as shown in the figure. Figure 1 and Figure 12 The receiving device 4 includes a feeding rack 41, a wire organizer 6, a wire guide 7, a winding coil 10, and a winding coil drive assembly 8. The wire organizer 6 is fixedly connected to the side of the feeding rack 41 near the punching device 2, and the winding coil 10 is rotatably connected to the side of the feeding rack 41 away from the punching device 2. The wire guide 7 is fixedly connected to the feeding rack 41 and is located between the wire organizer 6 and the winding coil 10. The winding coil drive assembly 8 is used to drive the winding coil 10 to wind the wire. After the elastic wire 100 is led out from the discharge end of the punching device 2, it passes through the wire organizer 6 and the wire guide 7 and is then wound onto the winding coil 10. The winding coil 10 is used to wind the finished elastic wire 100, the wire guide 7 is used to guide the elastic wire 100 to wind evenly on the winding coil 10, and the winding coil drive assembly 8 is used to drive the winding coil 10 to rotate, providing power for the winding of the elastic wire 100.

[0074] Both the low-position sensor 55 and the high-position sensor 54 are proximity switches, specifically photoelectric proximity switches, ultrasonic proximity switches, or magnetic induction proximity switches. This application uses the limit detection circuit of the buffer mechanism 5 used between the punching equipment 2 and the receiving equipment 4 as an example for explanation. (Refer to...) Figure 13 The low-position sensor 55 includes a first normally open switch S1, and the high-position sensor 54 includes a second normally open switch S2. The high-position sensor 54 and the low-position sensor 55 are electrically connected to a limit detection circuit, which includes:

[0075] The low-position detection module 11 is used to detect the position of the movable pulley 52, so as to send a low-position detection signal when the movable pulley 52 reaches the lowest limit of the buffer frame 51.

[0076] The first switch module 12 is electrically connected to the low-level detection module 11 to issue a first switch signal when a low-level detection signal is received.

[0077] The first execution module 13 is electrically connected to the first switch module 12 to trigger the first execution signal when the first switch signal is received. The first execution signal is specifically an acceleration signal of the wire winding drive assembly 8 for controlling the wire winding drive assembly 8 to drive the winding 10 to accelerate the take-up of the wire.

[0078] The high-position detection module 14 is used to detect the position of the movable pulley 52, so as to send a low-position detection signal when the movable pulley 52 reaches the highest limit of the buffer frame 51;

[0079] The second switch module 15 is electrically connected to the high-level detection module 14 to issue a second switch signal when a high-level detection signal is received.

[0080] The second execution module 16 is electrically connected to the second switch module 15 to trigger the second execution signal when a second switch signal is received. The second execution signal is specifically a deceleration signal of the wire winding drive assembly 8 for controlling the wire winding drive assembly 8 to drive the winding 10 to decelerate and take in the material.

[0081] When the low-position sensor 55 detects the moving pulley 52, it closes the first normally open switch S1 to send a low-position detection signal, which triggers the first switch module 12 to send a first switch signal, which in turn triggers the first execution module 13 to send a first execution signal, used to adjust the receiving device 4 to accelerate the receiving process; when the high-position sensor 54 detects the moving pulley 52, it closes the second normally open switch S2 to send a high-position detection signal, which triggers the second switch module 15 to send a second switch signal, which in turn triggers the second execution module 16 to send a second execution signal, used to adjust the receiving device 4 to decelerate the receiving process; thereby improving the automation level of the receiving speed control.
