Description

Technical Field

[0001] This utility model relates to the technical field of wire feeding equipment, specifically a wire feeding device for processing springs to prevent wire coils from tangling. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. Springs are generally made of spring steel. There are many types of springs; based on shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] In the prior art, such as in publication number CN217192314U, a wire feeding device for spring processing is disclosed. It includes a control box, with a winding reel on the top of the control box and a support frame fixedly mounted on one side. A slide rail is formed on the surface of the support frame, and a guide block is slidably connected inside the slide rail. A threaded rod is rotatably connected to the top of the guide block. The elastic force of the spring causes the locking block to reset and engage in another slot, increasing the friction between the rotating shaft and the support. This facilitates clamping the wire coil and prevents it from loosening when the spring machine suddenly stops, thus preventing the wire coil from becoming entangled. Reducing the loosening of the wire coil ensures smooth operation of the wire coil in later use and prevents jamming, guaranteeing the smooth operation of the device.

[0004] In the prior art, during the feeding process of the wire coil by the traction device, in order to avoid the wire coil bearing a large load, the wire coil itself must also be driven by an independent power device to rotate and release the wire. However, as the wire release process continues, the diameter of the wire coil will gradually decrease, which will cause the wire release speed to be lower than the feeding speed of the traction device. This speed difference will cause the wire release to be unstable, thereby increasing the risk of the wires tangling together. Therefore, this utility model provides a wire feeding device for spring processing to prevent wire coil tangling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wire feeding device for spring processing to prevent wire coil entanglement. It solves the problem that as the wire coil continues to be unwound, the diameter of the wire coil gradually decreases, which leads to the wire unwound speed being lower than the pulling speed of the traction device. This speed difference causes the wire unwound to become unstable, thereby increasing the risk of the wires entangled with each other.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding device for processing springs to prevent wire coil entanglement, comprising a machine base, a bracket mounted on one outer wall of the machine base, a rotating assembly on the machine base, a diameter-changing assembly on the top of the rotating assembly, and a wire-drawing assembly on the bracket; the wire-drawing assembly includes a slide rail mounted on the top surface of the bracket, a slider slidably connected to the top of the slide rail, side plates mounted on both outer walls of the slide rail, and pressure sensors mounted on the opposite outer surfaces of the two side plates; the slider slides on the slide rail and can contact any one of the pressure sensors.

[0007] Preferably, a U-shaped seat is installed on the top surface of the slider, and two wire rollers are rotatably arranged inside the U-shaped seat. A channel for pulling steel wire is formed between the two wire rollers. Two meshing gears are provided on one side surface of the U-shaped seat, and the two gears are respectively connected to the two wire rollers through shafts. A second motor for driving the two wire rollers to rotate is installed on the outer surface of the other side of the U-shaped seat.

[0008] Preferably, the rotating assembly includes a first motor mounted on the bottom surface of the machine base. The output shaft of the first motor extends movably through the bottom surface of the machine base and upwards. A turntable is mounted on the output shaft of the first motor. The bottom surface of the turntable is rotatably connected to the top surface of the machine base. The top surface of the turntable has four guide grooves arranged in a circular pattern.

[0009] Preferably, the bracket is also equipped with a controller, which is connected to the first motor, the second motor and the pressure sensor.

[0010] Preferably, the variable diameter assembly includes four columns, each with a fixed plate fixedly connected to its top and bottom. The lower fixed plate is fixedly installed on the top surface of the first turntable. A bidirectional lead screw is provided between two of the fixed plates. The top of the bidirectional lead screw movably passes through the bottom surface of one of the fixed plates and extends upward. A knob is installed on the top of the bidirectional lead screw. Threaded blocks are symmetrically threaded onto the outer wall of the bidirectional lead screw, and the threaded blocks are slidably connected to the columns. First connecting blocks are installed on the outer surfaces of the threaded blocks. A connecting rod is rotatably provided on each of the first connecting blocks. A second connecting block is rotatably provided between the two connecting rods located above and below. A support plate is installed on the outer surface of the second connecting block, and the bottom of the support plate is slidably disposed inside the turntable.

[0011] Preferably, multiple support legs are installed near the edge of the machine base, and a vertical rod is installed on the support. A wire ring is fixedly connected to the top of the vertical rod for guiding the steel wire.

[0012] Beneficial effects

[0013] This utility model provides a wire feeding device for processing springs with anti-winding steel wire coils. Compared with the prior art, it has the following advantages:

[0014] 1. The wire feeding device for the anti-winding spring processing of the steel wire coil involves a slider sliding on a slide rail during the wire feeding process. When the wire feeding speed is inconsistent with the feeding speed, the tension generated by the wire on the wire roller will cause the slider to move on the slide rail. If the slider comes into contact with any pressure sensor, the pressure sensor will transmit a signal to the controller. After receiving the signal, the controller controls the speed of the first motor according to the preset program. If the wire feeding speed is slow, the speed of the first motor is increased to speed up the wire coil feeding speed. If the wire feeding speed is fast, the speed of the first motor is decreased to keep the wire feeding speed consistent with the feeding speed, effectively preventing the steel wires from winding together.

[0015] 2. The wire feeding device for the anti-winding spring processing of the steel wire coil rotates the two-way screw by turning the knob, and the two threaded blocks move towards or away from each other. Through the transmission of the first connecting block, connecting rod and second connecting block, the wire support plate will move towards the center or spread out to the sides, which is convenient to adapt to steel wire coils of different diameters and improves the practicality of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides two technical solutions:

[0023] Figures 1-4 The first embodiment is shown: a wire feeding device for processing springs to prevent wire coil entanglement, including a machine base 1, a bracket 12 installed on one outer wall of the machine base 1, a rotating component 2 provided on the machine base 1, a diameter changing component 3 provided on the top of the rotating component 2, and a wire drawing component 4 provided on the bracket 12; the wire drawing component 4 includes a slide rail 41 installed on the top surface of the bracket 12, a slider 42 slidably connected to the top of the slide rail 41, side plates 47 installed on both outer walls of the slide rail 41, and pressure sensors 48 installed on the opposite outer surfaces of the two side plates 47; the slider 42 slides on the slide rail 41 and can contact any one of the pressure sensors 48.

[0024] A U-shaped seat 43 is mounted on the top surface of the slider 42. Two wire rollers 44 are rotatably mounted inside the U-shaped seat 43, forming a channel for traction of steel wire between the two wire rollers 44. Two meshing gears 45 are provided on one side surface of the U-shaped seat 43, and the two gears 45 are respectively connected to the two wire rollers 44 through shafts. A second motor 46 for driving the two wire rollers 44 to rotate is mounted on the outer surface of the other side of the U-shaped seat 43.

[0025] Specifically, the two wire rollers 44 are driven to rotate by the second motor 46, and the two wire rollers 44 are rotated synchronously by the meshing of the gear 45, thereby feeding the steel wire.

[0026] The rotating assembly 2 includes a first motor 21 installed on the bottom surface of the machine base 1. The output shaft of the first motor 21 extends movably through the bottom surface of the machine base 1 and upwards. A turntable 22 is installed on the output shaft of the first motor 21. The bottom surface of the turntable 22 is rotatably connected to the top surface of the machine base 1. Four guide grooves 23 are provided on the top surface of the turntable 22. The four guide grooves 23 are arranged in a circular pattern.

[0027] Specifically, the first motor 21 is started, which drives the turntable 22 to rotate, thereby causing the wire coil to rotate and be unloaded.

[0028] The bracket 12 is also equipped with a controller 5, which is connected to the first motor 21, the second motor 46 and the pressure sensor 48.

[0029] Specifically, during the wire feeding process, the slider 42 slides on the slide rail 41. When the wire feeding speed is inconsistent with the feeding speed, the tension generated by the wire on the wire roller 44 will cause the slider 42 to move on the slide rail 41. If the slider 42 comes into contact with any pressure sensor 48, the pressure sensor 48 will transmit a signal to the controller 5. After receiving the signal, the controller 5 controls the speed of the first motor 21 according to the preset program. If the wire feeding speed is slow, the speed of the first motor 21 is increased to speed up the wire feeding speed. If the wire feeding speed is fast, the speed of the first motor 21 is reduced to keep the wire feeding speed consistent with the feeding speed, effectively preventing the wires from tangling.

[0030] Figures 1-4 The second embodiment is shown, and its main difference from the first embodiment is that the variable diameter assembly 3 includes four columns 31. The top and bottom ends of each column 31 are fixedly connected to a fixing plate 32. The lower fixing plate 32 is fixedly installed on the top surface of the first turntable 22. A bidirectional lead screw 33 is provided between two fixing plates 32. The top end of the bidirectional lead screw 33 movably passes through the bottom surface of one of the fixing plates 32 and extends upward. A knob 39 is installed on the top end of the bidirectional lead screw 33. Threaded blocks 34 are symmetrically threaded on the outer wall of the bidirectional lead screw 33, and the threaded blocks 34 are slidably connected to the columns 31. First connecting blocks 35 are installed on the outer surfaces of the threaded blocks 34. A connecting rod 36 is rotatably provided on each first connecting block 35. A second connecting block 37 is rotatably provided between the two connecting rods 36 located above and below. A support plate 38 is installed on the outer surface of the second connecting block 37, and the bottom of the support plate 38 is slidably disposed inside the turntable 22.

[0031] Specifically, by rotating the knob 39 to rotate the bidirectional lead screw 33, the two threaded blocks 34 will move towards or away from each other. Through the transmission of the first connecting block 35, the connecting rod 36 and the second connecting block 37, the wire support plate 38 will move closer to the center or spread outwards, which is convenient for adapting to wire coils of different diameters and improves the practicality of the device.

[0032] Furthermore, the column 31 serves to guide the threaded block 34, ensuring that it can only move in a straight line along the column 31.

[0033] Multiple support legs 11 are installed on the bottom surface of the machine base 1 near the edge. A vertical rod 6 is installed on the support 12. A wire guide ring 61 is fixedly connected to the top of the vertical rod 6 for guiding the steel wire.

[0034] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art. In this embodiment,

[0035] Working principle: First, the wire coil is wrapped around the outside of the support plate 38. One end of the wire is passed through the guide ring 61 and two wire rollers 44 in sequence and installed on the spring processing equipment. When feeding the wire, the first motor 21 is started, which drives the turntable 22 to rotate, thereby rotating the wire coil to feed the wire. At the same time, the second motor 46 drives the two wire rollers 44 to rotate. The two wire rollers 44 rotate synchronously through the meshing of the gear 45, thereby drawing the wire.

[0036] During the feeding process, the slider 42 slides on the slide rail 41. When the wire feeding speed is inconsistent with the feeding speed, the tension generated by the wire on the wire roller 44 will cause the slider 42 to move on the slide rail 41. If the slider 42 comes into contact with any pressure sensor 48, the pressure sensor 48 will transmit a signal to the controller 5. After receiving the signal, the controller 5 controls the speed of the first motor 21 according to the preset program. If the wire feeding speed is slow, the speed of the first motor 21 is increased to speed up the wire feeding speed. If the wire feeding speed is fast, the speed of the first motor 21 is reduced to keep the wire feeding speed consistent with the feeding speed, effectively preventing the wires from tangling.
