Description

Technical Field

[0001] This utility model relates to the field of servo automatic feeding devices, and in particular to a servo automatic feeding device for stamping processing. Background Technology

[0002] Servo automatic feeding devices for stamping are automated equipment used to precisely feed raw materials into stamping machines. They are widely used in stamping production lines in industries such as automotive, electronics, and home appliances. Through a servo drive system, they control the feeding speed, position, and accuracy, greatly improving the automation, efficiency, and precision of stamping processes.

[0003] Existing technologies, such as the utility model patent with publication number CN203235853U, disclose a servo-driven stepping automatic feeding device. This patent employs a die base and a punch press mounted above the die base, and also includes crossbeams and several positioning dies mounted on the die base. Several robotic arms are mounted on the crossbeams, and a hydraulic cylinder telescopic arm is also included. This utility model enables faster stamping processes, achieving full automation of the stamping process from feeding to processing to unloading. Compared to other transfeeder methods, it offers higher process control efficiency, significantly improving production efficiency. Multiple processes can be completed by a single machine, reducing the number of operators. This structure can be used for any form of stamping processing, including cold, warm, and hot stamping.

[0004] The inventors discovered in daily use that existing servo automatic feeding devices, lacking precise limiting devices during the feeding process, may cause positional deviations in the stamped parts during processing. Inaccurate positioning leads to poor fit between the stamped parts and the die, affecting stamping quality and die life. Furthermore, the feeding device's inability to accurately limit positioning can cause misalignment of the stamped parts during processing. This misalignment not only affects production efficiency but may also lead to dimensional deviations in the stamped parts, impacting product yield. When the servo feeding device struggles to accurately limit positioning, the stamping pressure distribution during the stamping process becomes uneven, potentially causing surface defects in the stamped parts, such as dents, deformation, and cracks, thus affecting product quality.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0009] Preferably, the arc surface of the threaded tube is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded tube.

[0010] The effect achieved by the above components is that the groove can increase the friction between the hand and the threaded tube, preventing slippage when rotating the threaded tube.

[0011] Preferably, a limiting rod is fixedly connected inside the groove, and the limiting rod is slidably connected to the connecting rod.

[0012] The effect achieved by the above components is that the limiting rod can limit the connecting rod, preventing the connecting rod from shifting during use and improving the stability of the sliding of the connecting rod.

[0013] Preferably, the roller has a circular cross-section and is a rubber roller.

[0014] The effect achieved by the above components is that the rubber material can increase the friction between the roller and the contact surface, preventing the roller from getting stuck when limiting the five gifts.

[0015] Preferably, the upper surface of the servo machine tool is provided with an adjustment structure, the adjustment structure including two sleeve plates, both of which are fixedly connected to the servo machine tool. A slide plate is slidably connected to the inner wall of the sleeve plate, and the slide plate is fixedly connected to a fixed plate. Two insert rods are slidably connected to the opposite sides of the two sleeve plates, and the insert rods are slidably connected to the slide plate. A spring is sleeved on the arc surface of the insert rod, and the two ends of the spring are fixedly connected to the sleeve plate and the insert rod, respectively.

[0016] The effect achieved by the above components is as follows: when the height of the limiting structure needs to be adjusted, the plug rod is pulled to move, the plug rod drives the spring to stretch, then the plug rod is separated from the slide plate, then the fixed plate is moved, the fixed plate drives the slide plate to move, the slide plate slides on the inner wall of the sleeve plate, then the plug rod is aligned with the slide plate, then the plug rod spring is released to retract and drive the plug rod to be inserted into the slide plate for fixation.

[0017] Preferably, both ends of the slide plate are fixedly connected to slide rods, and the slide rods are slidably connected to the sleeve plate.

[0018] The effect achieved by the above components is that the slide bar can limit the slide plate and prevent it from deviating when sliding on the inner wall of the slide plate.

[0019] Preferably, a connecting rod is fixedly connected to one side of the two insertion rods that are close to each other, and the connecting rod has a circular cross-section.

[0020] The effect achieved by the above components is that when it is necessary to pull the plug rod, the connecting rod can be pulled directly, and the connecting rod can directly drive the two plug rods to move, avoiding the need to pull the plug rods one by one.

[0021] Compared with related technologies, the servo automatic feeding device for stamping provided by this utility model has the following advantages:

[0022] This utility model provides a servo automatic feeding device for stamping. By setting a limiting structure, it addresses the issue that existing servo automatic feeding devices, lacking precise limiting devices during the feeding process, may cause positional deviations in the stamped parts. Inaccurate positioning leads to poor fit between the stamped parts and the die, affecting stamping quality and die life. Furthermore, the difficulty in accurately limiting the feeding device can cause misalignment of the stamped parts during processing. This misalignment not only affects production efficiency but may also lead to dimensional deviations in the stamped parts, impacting product yield. When the servo feeding device cannot accurately limit the feeding, the stamping pressure distribution during the stamping process will be uneven, potentially causing surface defects in the stamped parts, such as dents, deformation, and cracks, affecting product quality. This device achieves convenient limiting of the stamped parts, allowing them to be stamped directly after loading, and can provide limiting functionality based on different stamped part models.

[0023] By setting an adjustment structure, the height of the limiting structure can be easily adjusted, and the limiting structure can be reasonably adjusted according to the height of the stamped part. Attached Figure Description
