Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal wire processing equipment, in particular to a self-adaptive wire drawing machine clamping mechanism with rapid clamping, a wire drawing machine and a control method thereof. BACKGROUND

[0002] The wire drawing machine is a key equipment for drawing a metal rod or tube with a large diameter into a wire with a small diameter through a die. The clamping mechanism as the starting station of the wire drawing machine directly affects the feeding efficiency, the stability of the wire drawing process and the quality of the finished product. At present, the common clamping mechanisms of the wire drawing machine mainly have the following forms: Manual threaded clamping mechanism: a plurality of bolts are used to radially clamp the workpiece from all around. This method is tedious and time-consuming, and the clamping force completely depends on the experience of the operator, which has poor consistency and is prone to cause insufficient clamping force to cause drawing slip or excessive clamping force to cause damage or even crushing of the workpiece surface. At the same time, it is difficult to ensure that the multiple bolts are pushed synchronously, and the workpiece centering accuracy is low.

[0003] Ordinary pneumatic or hydraulic chuck: the clamping jaw is driven by a gas cylinder or an oil cylinder. Although the efficiency is improved compared with the manual method, it usually lacks high-precision force detection and control function. The clamping force is roughly set by the system pressure, which is greatly affected by the gas / oil pressure fluctuation, and cannot realize accurate constant force clamping. In the long-term drawing process, due to the decrease of the workpiece diameter, vibration and other factors, the clamping force decay is prone to cause loosening accidents. In addition, the traditional chuck is a rigid clamping, which has poor adaptability to the initial roundness error or irregular shape of the workpiece, and is prone to cause single-point stress concentration.

[0004] Simple electric three-jaw chuck: although it can realize the synchronous movement of the three jaws, it is usually an open-loop control, which can only control the displacement (clamping diameter) and cannot sense and control the actual clamping force. It is helpless for the application scenarios that require accurate control of the clamping force to avoid damage to high-strength and high-surface-quality workpieces (such as special alloys and precision pipes). At the same time, it lacks real-time monitoring and safety interlocking of whether the workpiece is in place and whether the clamping state is normal.

[0005] In summary, the existing wire drawing machine clamping mechanism has the problems of low adjustment efficiency, poor centering accuracy, uncontrollable and unstable clamping force, weak adaptability to the workpiece, lack of process monitoring and safety warning, etc. This has become one of the bottlenecks restricting the beat improvement, process stability guarantee and high-quality product production of the wire drawing automatic production line. Therefore, there is an urgent need for a new clamping mechanism integrating rapid clamping, accurate force control, self-adaptive adjustment and intelligent monitoring. SUMMARY

[0006] The technical problem to be solved by the present application is to provide a self-adaptive wire drawing machine clamping mechanism, a wire drawing machine and a control method, which can solve the problems of low clamping efficiency, rough control of clamping force, easy slipping or damage to workpieces, lack of safety monitoring and the like in the prior art.

[0007] The technical solution for solving the above technical problem is as follows: a self-adaptive wire drawing machine clamping mechanism with fast clamping, comprising: A clamping seat is arranged on the workbench of the wire drawing machine; A plurality of clamping jaw assemblies are arranged on the clamping seat and are uniformly distributed in the circumferential direction; each clamping jaw assembly comprises a clamping jaw slider that can move linearly in the radial direction and a chuck head arranged at the front end of the clamping jaw slider; A synchronous driving mechanism is arranged on the clamping seat and is in transmission connection with the clamping jaw sliders for synchronously driving all the clamping jaw sliders to move equidistantly in the radial direction; A pressure detection module is arranged on at least one chuck head for real-time detection of the radial clamping force of the chuck head on the workpiece; A central controller is in signal connection with the synchronous driving mechanism and the pressure detection module, receives the radial clamping force detected by the pressure detection module, and controls the synchronous driving mechanism according to a preset target clamping force.

[0008] The present application has the following advantages: the synchronous driving mechanism is used to realize synchronous radial movement of multiple clamping jaws, which greatly improves the clamping speed and centering accuracy compared with manual or non-synchronous driving; the introduction of pressure detection and closed-loop control makes the clamping force changeable and accurately settable and maintainable, which fundamentally solves the problems of slipping due to insufficient clamping force or damage to workpieces due to excessive clamping force.

[0009] On the basis of the above technical solution, the present application can be further improved as follows.

[0010] Further, the synchronous driving mechanism comprises: a driving bevel gear arranged at the center of the clamping seat and driven by a servo motor; a same number of driven bevel gears as the number of clamping jaw assemblies, each of which is connected with a clamping jaw slider through a ball screw pair; all the driven bevel gears are in meshing connection with the driving bevel gear; the rotary motion of the servo motor is synchronously transmitted to all the driven bevel gears through the driving bevel gear, thereby driving all the clamping jaw sliders to move synchronously in the radial direction.

[0011] The beneficial effect of the further scheme is that the ball screw driving scheme is compact in structure, high in transmission precision, fast in response speed, and can reliably convert the rotary motion of a single servo motor into high-precision linear synchronous motion of multiple clamping jaws, and is high in mechanical reliability.

[0012] Further, the chuck is connected to the front end of the clamping jaw slider through a floating connector; the floating connector allows the chuck to adaptively float within a certain angle and radial range.

[0013] The beneficial effect of the further scheme is that the design of the floating connector enables the chuck to have certain adaptive ability, can compensate for the slight roundness error or surface unevenness of the workpiece itself, make the clamping force more uniform, avoid excessive local stress caused by rigid clamping, and is particularly suitable for workpieces with high surface quality requirements.

[0014] Further, the floating connector is a universal ball hinge structure or a flexible rubber joint; the clamping surface of the chuck is arc-shaped or V-shaped, and the surface is inlaid with replaceable wear-resistant liners.

[0015] The beneficial effect of the further scheme is that the universal ball hinge or flexible joint provides multi-degree-of-freedom floating. The combination of the arc-shaped / V-shaped clamping surface and the replaceable wear-resistant liner increases the contact area and friction, protects the surface of the workpiece, and the liner can be easily replaced after wear, reducing maintenance costs.

[0016] Further, the pressure detection module includes a piezoelectric force sensor embedded between the chuck and the clamping jaw slider.

[0017] The beneficial effect of the further scheme is that the piezoelectric or thin film pressure detection module can detect dynamic clamping force with high sensitivity and high response speed, providing accurate feedback signals for closed-loop control.

[0018] Further, the clamping mechanism further includes a displacement detection module for detecting the radial displacement of the clamping jaw slider, and the displacement detection module is signal connected with the central controller.

[0019] The beneficial effect of the further scheme is that the displacement detection module provides accurate feedback of the position of the clamping jaw, and in combination with the force sensor signal, a more complex force-position hybrid control strategy can be implemented to optimize the clamping process.

[0020] Further, the clamping mechanism further includes a workpiece detection module for detecting whether the workpiece is placed in place and the initial position, and the workpiece detection module is signal connected with the central controller.

[0021] The beneficial effect of the further scheme is that the workpiece detection module can automatically sense whether the workpiece is placed in place and its rough position, which provides a premise for realizing one-key automatic clamping process, reduces manual intervention, and improves the degree of automation.

[0022] Further, the clamping seat is further provided with an audible and visual alarm and a state indicating lamp connected with the central controller.

[0023] The beneficial effect of the further scheme is that the audible and visual alarm and the state indicating lamp provide intuitive human-machine interaction.

[0024] The present application also provides a wire drawing machine comprising the quick clamping self-adaptive wire drawing machine clamping mechanism as described above.

[0025] The beneficial effect of the above scheme is that the clamping mechanism is integrated into the wire drawing machine, which can significantly improve the automation level, processing stability and safety of the whole machine.

[0026] The present application also provides a control method of the quick clamping self-adaptive wire drawing machine clamping mechanism as described above, comprising the following steps: S1: clamping preparation: the operator places the workpiece in the clamping center area, and the central controller confirms the workpiece in place through the workpiece detection module; S2: quick centering and pre-tightening: the central controller controls the synchronous driving mechanism to act, drives all the jaw assemblies to move inward synchronously until the chuck contacts the surface of the workpiece, and completes the quick centering and pre-contact; S3: self-adaptive accurate clamping: the central controller switches to force control mode, controls the synchronous driving mechanism to continue to apply force according to the radial clamping force feedback by the pressure detection module, until the clamping force reaches the preset target clamping force F_set; S4: process constant force maintenance: during the wire drawing operation, the central controller continuously monitors the signal of the pressure detection module, and if the radial clamping force F_real deviates from the target clamping force F_set by more than the allowable error ΔF, the synchronous driving mechanism is controlled to make compensatory fine adjustment, so that the target clamping force F_real is maintained within the interval (F_set±ΔF); S5: loosening and resetting: after the wire drawing operation is completed, the central controller controls the synchronous driving mechanism to reverse, drives all the jaw assemblies to move outward to the open position synchronously, and waits for the next clamping.

[0027] The beneficial effect of the above scheme is that the control method defines a complete and intelligent clamping process, from detection, centering, accurate clamping, process maintenance to loosening, each step is based on sensor feedback and logical judgment, and realizes programmed and intelligent management of the clamping process.

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] Example 1 like Figure 1 As shown, this embodiment discloses a quick-clamping adaptive wire drawing machine clamping mechanism, including a clamping base 1, which is used to fix to the worktable of the wire drawing machine; The gripper assembly 2 has three or more gripper assemblies 2, which are evenly distributed on the clamping base 1 along the circumferential direction; each gripper assembly 2 includes a gripper slider 21 that can move linearly in the radial direction and a chuck 22 installed at the front end of the gripper slider 21. Synchronous drive mechanism 3 is provided on the clamping base 1. The synchronous drive mechanism 3 is connected to the gripper slider 21 for synchronously driving all the gripper sliders 21 to move synchronously and equidistantly in the radial direction. Pressure detection module 4, at least one of the chucks 22 is provided with pressure detection module 4, used to detect the radial clamping force of the chuck 22 on the workpiece in real time; The central controller 5 is connected to the synchronous drive mechanism 3 and the pressure detection module 4 by signal, and is used to receive the radial clamping force detected by the pressure detection module 4, and control the synchronous drive mechanism 3 according to the preset target clamping force.

[0031] The synchronous driving mechanism 3 comprises: a driving bevel gear 32 arranged at the center of the clamping seat 1 and driven by a servo motor 31; a same number of driven bevel gears 33 as the jaw assemblies 2, each of which is connected with the jaw slider 21 through a ball screw pair 34; all the driven bevel gears 33 are in mesh with the driving bevel gear 32; the rotary motion of the servo motor 31 is synchronously transmitted to all the driven bevel gears 33 through the driving bevel gear 32, thereby driving all the jaw sliders 21 to move radially synchronously.

[0032] The chuck 22 is connected with the front end of the jaw slider 21 through a floating connector 6; the floating connector 6 allows the chuck 22 to adaptively float within a certain angle and radial range.

[0033] The floating connector 6 is a universal ball hinge structure or a flexible rubber joint; the clamping surface of the chuck 22 is arc-shaped or V-shaped, and the surface is inlaid with a replaceable wear-resistant liner 221.

[0034] The pressure detection module 4 comprises a piezoelectric force sensor embedded between the chuck 22 and the jaw slider 21.

[0035] The clamping mechanism further comprises a displacement detection module 7 for detecting the radial displacement of the jaw slider 21, which is a linear grating ruler arranged on the clamping seat 1 or a rotary encoder coaxially connected with the servo motor 31; the displacement detection module 7 is signal-connected with the central controller 5.

[0036] The clamping mechanism further comprises a workpiece detection module 8 for detecting whether the workpiece is placed in place and the initial position, which comprises a laser displacement sensor arranged at the center of the clamping position for detecting whether the workpiece is placed in place and the initial position; the workpiece detection module 8 is signal-connected with the central controller 5.

[0037] The clamping seat 1 is further provided with an audible and visual alarm 9 and a status indicator light 10 connected with the central controller 5.

[0038] In one specific embodiment of the present application, the following parts are included: Clamping seat 1: a disc-shaped cast iron or steel structural member, rigidly fixed on the drawing machine workbench through flanges and bolts. The center is provided with a through hole for the workpiece to pass through. The side wall is provided with a cooling liquid interface connected with the external cooling system.

[0039] Jaw assembly 2: there are three in total, evenly distributed at intervals of 120° along the circumference of the clamping seat 1. Each assembly comprises: Clamping jaw slider 21: a T-shaped slider that can slide precisely in the T-shaped slot radially arranged in the clamping seat 1. The slider has a cooling liquid channel drilled inside, and is connected to the floating connector 6 at the front end and to the nut of the ball screw pair 34 at the rear end.

[0040] Chuck 22: the clamping surface is designed as a V-shaped groove with an angle of 120° to better accommodate circular workpieces. The surface of the V-shaped groove is fixed with replaceable wear-resistant liners 221 through screws. In this example, the liner material is reinforced nylon composite, and small hard alloy particles are embedded inside to enhance wear resistance.

[0041] Floating connector 6: adopts a universal ball hinge structure. It includes a ball seat connected to the front end of the clamping jaw slider 21 through a thread, a ball head rod connected to the back of the chuck 22, and a pressure bearing between the two. (The specific structure is a conventional technology in the field, and will not be described here.) This structure allows the chuck 22 to adaptively swing within a cone angle of about ±3 degrees, and can have a small elastic displacement in the axial direction to absorb vibration and compensate for deviations.

[0042] Synchronous drive mechanism 3: servo motor 31, choose low inertia servo motor with brake, installed in the rear end of the clamping seat 1 through the motor base.

[0043] Driving bevel gear 32 and driven bevel gear 33: the driving bevel gear 32 is installed on the output shaft of the servo motor 31 and located in the center of the clamping seat 1. Three driven bevel gears 33 are supported by bearings in the clamping seat 1, their axes are perpendicular to and intersect with the axis of the driving bevel gear 32, and they are meshed with the driving bevel gear 32 respectively. This constitutes a bevel gear synchronizer, ensuring that the input shaft and the output shaft rotate strictly synchronously.

[0044] Ball screw pair 34: the center of each driven bevel gear 33 is connected to one end of a precision ball screw through a key. The nut on each ball screw is fixed with the corresponding clamping jaw slider 21. Therefore, the rotational motion of the driven bevel gear 33 is converted into high-precision linear motion of the clamping jaw slider 21. The forward and reverse rotation of the servo motor 31 drives the three-jaw synchronous tightening or loosening.

[0045] Pressure detection module 4: a ring-shaped piezoelectric force sensor is embedded between the ball seat of the floating connector 6 of each clamping jaw and the clamping jaw slider 21. The piezoelectric force sensor can accurately measure the axial force transmitted through the ball seat, i.e. the radial clamping component of the workpiece by the clamping jaw. The signals of the three sensors are connected to the central controller 5.

[0046] Displacement detection module 7: a high-resolution multi-turn absolute rotary encoder coaxially connected with the servo motor 31 is used as an indirect displacement detection device. The controller 5 can accurately calculate the theoretical radial position of each clamping jaw by reading the encoder position combined with the lead of the screw.

[0047] Workpiece detection module 8: A small laser displacement sensor is installed at the center of the front face of the clamping base 1, with its spot pointing towards the clamping center. When the workpiece is placed in, if the laser is blocked or the ranging value changes abruptly, the controller can determine that the workpiece is roughly in place.

[0048] Central Controller 5: An industrial PLC (such as Siemens S7-1200) is used as the main controller and is installed in the wire drawing machine cabinet. It is connected to the servo drive, all sensors, audible and visual alarm 9, and status indicator lights 10 via digital and analog modules. A touch screen HMI is used for parameter setting (target clamping force F_set, safety threshold F_safe, etc.), mode selection, and status display.

[0049] Example 2 This embodiment provides a wire drawing machine, including the adaptive wire drawing machine clamping mechanism with rapid clamping as described above. Integrating the clamping mechanism into the wire drawing machine can significantly improve the automation level, processing stability, and safety of the entire machine.

[0050] Example 3 This embodiment discloses a control method for a quick-clamping adaptive wire drawing machine clamping mechanism as described above, including the following steps: S1: Clamping preparation: The operator places the workpiece in the clamping center area, and the central controller 5 confirms that the workpiece is in place through the workpiece detection module (8); S2: Rapid centering and pre-tightening: The central controller (5) controls the synchronous drive mechanism (3) to move, driving all gripper assemblies (2) to move inward synchronously until the chuck (22) contacts the workpiece surface, completing rapid centering and pre-contact; S3: Adaptive precision clamping: The central controller (5) switches to force control mode and controls the synchronous drive mechanism (3) to continue applying force according to the radial clamping force fed back by the pressure detection module (4) until the clamping force reaches the preset target clamping force F_set; S4: Constant force maintenance during the wire drawing process: The central controller (5) continuously monitors the signal of the pressure detection module (4). If the radial clamping force F_real deviates from the target clamping force F_set by more than the allowable error ΔF, the synchronous drive mechanism (3) is controlled to make compensatory fine adjustments so that the target clamping force F_real is maintained within the range of (F_set±ΔF). S5: Clamping and Resetting: After the wire drawing operation is completed, the central controller (5) controls the synchronous drive mechanism (3) to reverse, driving all gripper assemblies (2) to move outward synchronously to the open position, waiting for the next clamping.

[0051] It also includes step S6: data recording and traceability: the central controller 5 records the maximum clamping force, average clamping force, clamping time and displacement data of each clamping process, and binds them with the workpiece identification to form a traceable clamping process file.

[0052] In the S4 stage, if the PLC detects that the force value of a certain gripper drops by more than 30% within 100 milliseconds (for example, from 8000N to below 5000N), it will immediately determine that the gripper is abnormally loose. The PLC will not only trigger the high-frequency sound and light alarm 9 and the red indicator light to flash, but also send an emergency stop signal to the wire drawing machine host through the emergency stop relay.

[0053] This embodiment also discloses a computer-readable storage medium for a calculator, on which a computer program is stored. When the program is executed by a processor, it implements the control method for the adaptive wire drawing machine clamping mechanism with rapid clamping as described above.
