U-bolt Tightening Machine

Description

U-bolt tightening machine is a high-precision automated system designed for accurate and efficient tightening of U-bolts in axle and suspension assembly lines.
It integrates electric nutrunners, torque and angle control, and multi-station synchronization to ensure consistent fastening quality and high production efficiency.

Basic Functions and Performance Description of the Tightening Machine Equipment:

1, Capable of setting upper/lower limit torque values, target values, and other process parameters, with modification functionality.

2,The tightening system features emergency stop protection, parameter protection (process parameters, control parameters, internal parameters, etc.), and overload/overcurrent/overvoltage/overspeed protection for motors and drives.

3, Equipped with time monitoring, zero-speed holding, and fault alarm functions.

4, Automatic socket engagement (cap recognition), automatic retraction (load relief), and standby functionality.

5, Self-diagnosis and alarm for system faults, zero-drift recognition, compensation, and calibration capabilities.

6, Multi-step tightening functionality with programmable stages.

7, Audible and visual alarms with numerical display (e.g., for failed tightening, missed fasteners, or system faults).

8, Jog control (single/multi-axis) and automatic cycle operation.

9, Communication ports for integration into factory network systems.

10, Real-time dynamic display of torque/angle values, automatic recognition of tightening results, auto-alarms, and fault diagnostics.

11, Simultaneous on-screen display of torque/angle curves and graphical tightening profiles.

12, English HMI with touch input for modifying workpiece process and control parameters.

13, Forward/reverse rotation, stepless speed adjustment, and programming capabilities.

14, Torque control, torque control + angle monitoring, angle control + torque monitoring, torque control + angle control, multi-step/synchronous/asynchronous/multi-speed control.

15, False torque recognition functionality.

16, Speed setting and display control for pre-tightening, transition tightening, and final tightening stages.

17, Sequential/simultaneous/multi-step tightening with zero-speed holding.

18, Multiple tightening programs and fastening modes with parameter selection for mixed-model assembly line compatibility.

19, Multi-position "model selection" switch on operation panel for preset tightening parameters, eliminating need for control cabinet adjustments.

20, Pass/fail indicators, buzzer alarms, and over-torque alerts. Failed tightenings can be automatically reversed and retried via reset button or manually corrected using forward/reverse switches.
