Description

Technical Field

[0001] This utility model relates to the field of wire straightening machines, specifically a straightening machine for spring production. Background Technology

[0002] A wire straightening machine for spring production is a key piece of equipment used in the spring manufacturing process to straighten coiled or bent spring steel wires. It uses multiple sets of staggered straightening rollers to repeatedly bend and elastically deform the steel wire, effectively eliminating shape defects such as bending and warping that occur during rolling or winding, ensuring the wire is straight. This equipment not only inspects the quality of the steel wire and filters out surface cracks and inclusions, but also changes the residual stress distribution on the surface of the steel wire, transforming tensile stress into compressive stress, thereby significantly improving the fatigue performance of the steel wire and providing a high-quality material basis for subsequent spring coiling processes.

[0003] Currently, straightening machines used for straightening steel wires can straighten steel wires that are about to be bent, improving the production quality of springs. However, there is a problem in actual operation: before the steel wires are straightened in batches, the operator needs to adjust the straightening machine to ensure that the straightened steel wires meet the straightening standards. During the adjustment process, the operator relies solely on visual judgment to determine the straightening accuracy of the steel wires, which undoubtedly reduces the production quality of springs. In view of this, the inventor urgently needs to design a detection component that can quickly determine the straightening accuracy of steel wires, thereby improving the straightening accuracy of steel wires. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a straightening machine for spring production, so as to solve the technical problem that it is difficult to guarantee the stability and efficiency of steel wire straightening when judging the straightening accuracy by manual visual inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linear motion machine for spring production, comprising a linear motion machine body, wherein four sets of detection components are provided on one side of the steel wire outlet of the linear motion machine body, and the four sets of detection components are distributed on both sides of the steel wire; The detection assembly includes a mounting plate with an adjusting screw threaded onto it. The end of the adjusting screw is rotatably connected to a movable frame via a thrust bearing. A mounting frame is provided on the side of the movable frame near the steel wire. A pressure sensor is fixedly installed between the mounting frame and the movable frame. A pressure roller is rotatably installed on the side of the mounting frame near the steel wire.

[0006] By adopting the above technical solution, the bending of the steel wire will squeeze the pressure roller, and the pressure will be transmitted to the pressure sensor through the mounting frame and quantified, turning subjective visual judgment into objective data judgment.

[0007] Furthermore, the pressure roller abuts against the steel wire, and a gap is formed between the two pressure rollers for the steel wire to pass through. When the steel wire bends, it abuts against the pressure roller and transmits the pressure to the pressure sensor.

[0008] By adopting the above technical solution, when the bent steel wire passes through the gap formed by the pressure roller, lateral pressure is generated. This pressure directly and sensitively reflects the straightness deviation, has strong anti-interference, and is very suitable for industrial sites.

[0009] Furthermore, two guide rods are fixedly installed on the movable frame, the guide rods pass through the mounting plate, and a handwheel is fixedly installed at the outer end of the adjusting screw.

[0010] By adopting the above technical solution, the guide rod provides precise guidance for the movement of the mobile frame, ensuring that it can only move in a straight line and eliminating deflection or jamming. This ensures that the pressure roller is always facing the steel wire, so that the pressure sensor only bears positive pressure and the reading is accurate and reliable.

[0011] Furthermore, the mounting plate and the lower bolts of the linear machine body are mounted on the support plate.

[0012] By adopting the above technical solution, the mounting plate and the main body of the linear machine are integrated through the support plate, providing a solid and unified reference surface, ensuring the rigidity and stability of the relative position of the main unit and the detection components, and effectively avoiding detection errors caused by vibration.

[0013] Furthermore, a control screen is installed on one side of the surface of the support plate, and the four sets of pressure sensors are electrically connected to an external power supply through the control screen. The control screen is used to control and display the pressure threshold and detection data of the pressure sensors.

[0014] By adopting the above technical solutions, the control panel realizes centralized visualization and intelligent management of data. It can display the readings of each pressure sensor in real time and can alarm when the pressure exceeds the limit. It realizes online full inspection and automatic judgment, which greatly improves efficiency and timeliness.

[0015] Furthermore, a projection mechanism is provided above the mounting plate for projecting a visible straight line onto the pre-displacement point of the steel wire.

[0016] The projection mechanism includes a fixed plate on which a horizontal line projector is mounted. The horizontal line projector is electrically connected to an internal power source via a switch.

[0017] By adopting the above technical solution, the projection mechanism projects a visible baseline through a horizontal line projector, providing intuitive optical guidance for threading the steel wire. This makes the initial alignment operation simple and standardized, significantly reducing the difficulty of operation and preparation time, and improving efficiency.

[0018] In summary, the present invention has the following main advantages: 1. This utility model uses a detection assembly to set four sets of detection components with pressure sensors at the main outlet of the straightening machine, which realizes the quantitative detection of the straightening accuracy of the steel wire. The system uses the pressure roller to contact the steel wire and convert the curvature into a pressure signal, which is measured by the pressure sensor and transmitted to the control screen for display. This replaces the traditional manual visual judgment, making the detection results objective and repeatable, and significantly improving the quality consistency and control accuracy of spring production. 2. In this utility model, the position of the pressure roller can be precisely adjusted by the handwheel and adjusting screw to adapt to steel wires of different specifications, and the guide rod ensures the stability of the adjustment process.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In this embodiment: A linear motion machine for spring production, such as Figure 1-4 As shown, it includes a linear machine body 1, and four sets of detection components 3 are provided on one side of the steel wire 5 outlet of the linear machine body 1, and the four sets of detection components 3 are distributed on both sides of the steel wire 5. The detection component 3 includes a mounting plate 301, on which an adjusting screw 305 is threadedly connected. The end of the adjusting screw 305 is rotatably connected to a movable frame 302 via a thrust bearing 307. A mounting frame 303 is provided on the side of the movable frame 302 near the steel wire 5. A pressure sensor 304 is fixedly installed between the mounting frame 303 and the movable frame 302. A pressure roller 309 is rotatably installed on the side of the mounting frame 303 near the steel wire 5.

[0023] The bending of the steel wire 5 will squeeze the pressure roller 309. The pressure is transmitted to the pressure sensor 304 through the mounting bracket 303 and quantified, transforming subjective visual judgment into objective data judgment. This fundamentally eliminates human error, significantly improves the consistency and accuracy of the test, and lays the foundation for high-quality spring production.

[0024] See Figure 3 , Figure 4 The pressure roller 309 abuts against the steel wire 5, and a gap is formed between the two pressure rollers 309 for the steel wire 5 to pass through. When the steel wire 5 bends, it abuts against the pressure roller 309 and transmits the pressure to the pressure sensor 304. When the bent steel wire 5 passes through the gap formed by the pressure roller 309, it generates lateral pressure. This pressure directly and sensitively reflects the straightness deviation, has strong anti-interference, and is very suitable for industrial sites. At the same time, it simplifies the complex spatial straightness detection to the monitoring of the readings of four pressure sensors 304. Operators do not need to process complex data and can intuitively judge the direction and degree of bending. The logic is simple, which greatly reduces the threshold for use and facilitates promotion.

[0025] See Figure 3 , Figure 4 Two guide rods 306 are fixedly installed on the movable frame 302. The guide rods 306 pass through the mounting plate 301. A handwheel 308 is fixedly installed on the outer end of the adjusting screw 305. The guide rods 306 provide precise guidance for the movement of the movable frame 302, ensuring that it can only move in a straight line and eliminating deflection or jamming. This ensures that the pressure roller 309 is always facing the steel wire 5, so that the pressure sensor 304 only bears positive pressure and the reading is accurate and reliable. At the same time, the handwheel 308 makes manual fine adjustment possible. The operator can easily and accurately set the detection gap to adapt to different steel wires, improve the efficiency of changeover and the convenience of operation, and reduce the difficulty of debugging.

[0026] See Figure 1 , Figure 2The mounting plate 301 and the lower bolts of the linear machine body 1 are installed on the support plate 2. The mounting plate 301 and the linear machine body 1 are integrated through the support plate 2, providing a solid and unified reference surface. This ensures the rigidity and stability of the relative position of the host and the detection component 3, effectively avoiding detection errors caused by vibration. At the same time, this modular design greatly facilitates the overall transportation of the equipment, the optimization of the production line layout, and the later maintenance. When needed, the entire module can be lifted away without cumbersome disassembly, reducing the overall maintenance cost.

[0027] See Figure 1 , Figure 2 A control panel 4 is installed on one side of the support plate 2. Four pressure sensors 304 are electrically connected to an external power supply through the control panel 4. The control panel 4 is used to control and display the pressure threshold and detection data of the pressure sensors 304. The control panel 4 realizes centralized visualization and intelligent management of data. It can display the readings of each pressure sensor 304 in real time and can alarm when the pressure exceeds the limit. It realizes online full inspection and automatic judgment, which greatly improves efficiency and timeliness. At the same time, it provides data support for process optimization, facilitates quality traceability and analysis, and can be easily expanded into a closed-loop control system in the future. It can automatically adjust the straightening parameters according to the detection results to realize intelligent production.

[0028] See Figure 1 , Figure 2 , Figure 3 A projection mechanism 6 is provided above the mounting plate 301 for projecting a visible straight line onto the pre-displacement point of the steel wire 5.

[0029] The projection mechanism 6 includes a fixed plate 601, on which a horizontal line projector 602 is mounted. The horizontal line projector 602 is electrically connected to an internal power supply via a switch.

[0030] The projection mechanism 6 projects a visible baseline through the horizontal line projector 602, providing intuitive optical guidance for threading the steel wire 5. This makes the initial alignment operation simple and standardized, significantly reducing the difficulty of operation and preparation time, and improving efficiency. At the same time, precise alignment avoids the steel wire end from being forced through at an angle, which could damage components such as the pressure roller 309, protecting expensive precision parts, eliminating safety hazards, and improving equipment safety.

[0031] The implementation principle of this embodiment is as follows: The straightened steel wire 5 is sent out from the main body 1 of the straightening machine and passes through the gap formed by the pressure rollers 309 on the four sets of symmetrically arranged detection components 3. The operator can drive the adjusting screw 305 by turning the handwheel 308, thereby pushing the moving frame 302 to move along the guide rod 306 to accurately adjust the position of the pressure rollers 309 to adapt to steel wires 5 of different specifications. When the steel wire 5 is bent, it will squeeze the pressure roller 309 on one side. This pressure is transmitted to the pressure sensor 304 through the mounting frame 303. The pressure sensor 304 converts the physical pressure into an electrical signal and transmits it to the control screen 4 for real-time display and threshold judgment. In addition, the horizontal line projector 602 of the projection mechanism 6 can pre-project the baseline to assist the initial centering of the steel wire 5. By quantifying the straightness deviation of the steel wire into a pressure signal, the straightening accuracy can be quickly and objectively detected.

[0032] In this embodiment, both the pressure sensor 304 and the horizontal line projector 602 can be existing products. Only the function is limited, not the model, to avoid excessive description.

[0033] In this embodiment, the electric drive, adjustment, and cutting functions of the linear machine can all be achieved using existing technologies, and the applicant will not elaborate further here.

[0034] In some other embodiments: to avoid longitudinal bending of the steel wire 5 due to gravity, a support plate is provided below the displacement path of the steel wire 5, thereby further improving the practicality of bending detection on the left and right sides in this utility model.

[0035] In some other embodiments: the detection component 3 is not limited to being installed on the left and right sides of the steel wire 5, but can be installed at different positions on the steel wire 5 to improve the applicability of the detection component 3.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
