Abstract
Description
Technical Field
[0001] This invention relates to the field of grooving machines, and in particular to an automatic feeding grooving machine. Background Technology
[0002] CNC grooving machines, also known as slotting machines, are used to create V-shaped grooves of a certain depth at the bending points of stainless steel plates, ordinary steel plates, aluminum plates, copper plates, and composite plates with a thickness of less than 4mm before bending and forming. Workpieces produced by this process have small bending radius, minimal color change, low bending force, and reduced straightness error of the bending edges of narrow and long workpieces. Furthermore, workpieces with complex cross-sectional shapes can be bent using general-purpose molds on ordinary bending machines. This product is widely used in industries such as stainless steel processing, building decoration, kitchen equipment, door manufacturing, elevator manufacturing, splicing security doors, and shipbuilding technology.
[0003] Existing grooving machines typically rely on manual loading, positioning, and unloading operations when processing sheet metal and other metal workpieces. Traditional equipment lacks automated feeding and positioning systems, resulting in low processing efficiency, high labor intensity, and difficulty in ensuring the accuracy and consistency of workpiece positioning during processing. Furthermore, traditional grooving machine feeding devices are usually simple in structure and single in function, often using fixed pushers or conveyor belts, making it difficult to adapt to the flexible feeding needs of workpieces of different sizes and orientations. Especially when workpieces require rotational positioning, centering transport, or alternating multi-station operations, existing feeding devices often fail to achieve precise positioning and orientation adjustment, easily leading to workpiece misalignment, jamming, or low repeatability accuracy, affecting the quality and continuity of subsequent grooving processing. In addition, existing grooving machine feeding devices often lack effective limiting and centering guiding mechanisms, making workpieces prone to skew during transport, further affecting processing stability.
[0004] Therefore, a new technology needs to be developed to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution: 1. Through the combined design of the pressure plate assembly, tool holder module and feeding device, it can realize fully automatic feeding, positioning and grooving. Through the coordinated work of the feeding device, workpiece pushing mechanism, limit stop mechanism and workpiece conveying and rotating mechanism, it can realize the automatic conveying, positioning and rotation of workpiece from the feeding table to the processing station, which greatly improves processing efficiency and reduces manual intervention. II. By combining the design of a feeding table, a workpiece pushing mechanism, a workpiece conveying and rotating mechanism, and a limiting and stopping mechanism, the workpiece pushing mechanism is used to move the workpiece from the input side to the output side. The workpiece conveying and rotating mechanism is used to convey the workpiece from the feeding table to the workpiece placement table via the output side, or to rotate the workpiece horizontally and then convey it from the feeding table to the workpiece placement table via the output side. The limiting and stopping mechanism is used to limit and stop the workpiece on both sides to restrict the workpiece to the middle area of the conveying direction of the feeding table. In this way, it can realize automatic workpiece pushing, adjustable posture, accurate positioning and flexible feeding capability, solve the problems of workpiece offset, jamming or low accuracy of repeated positioning, ensure processing stability and ensure the quality and continuity of subsequent grooving processing. Third, the workpiece conveying and rotating mechanism can realize the horizontal rotation of the workpiece to meet the needs of different processing directions. The workpiece posture change can be completed without manual intervention, which enhances the adaptability and intelligence of the equipment and enables it to have the function of automatic workpiece posture adjustment, thus reducing manual labor. IV. By setting a limit stop mechanism, the workpiece can be limited on both sides, so that the workpiece always travels in the middle area of the feeding table conveying direction, effectively preventing the workpiece from deviating and improving the feeding centering accuracy. 5. By installing sensors on both sides of the feeding table, it is equipped with the ability to identify the length of the workpiece. The length of the workpiece can be identified in real time, providing a basis for the adjustment of the pushing and limiting mechanism, and realizing adaptive feeding control. VI. By adopting multiple independently lifting workpiece pushing units in the workpiece pushing mechanism, and enabling overall lateral movement according to the length and position of the workpiece, the device can adapt to the pushing needs of workpieces of different specifications and improve its versatility. 7. By equipping the rotating mechanism with a stop mechanism, the rotating shaft can be locked in the non-rotating state to prevent the workpiece from rotating accidentally during the conveying process and to ensure the stability of the conveying process. 8. It adopts a multi-stage transmission and guidance combination of lead screw, belt, and guide mechanism to achieve smooth execution of pushing, lateral movement, lifting and other actions. The structure layout is reasonable, the motion accuracy is high, and the service life is long. In addition, each functional mechanism is relatively independent. For example, the pushing unit, rotating mechanism and limit mechanism are all installed in a modular way, which is convenient for disassembly, replacement and maintenance, and reduces the cost of use.

The first limit drive cylinder 99 and the second limit drive cylinder 902 drive the first limit stop block 98 and the second limit stop block 901 to move up and down, so that the upper end of the first limit stop block 98 or the second limit stop block 901 extends upward above the through groove 16 to limit and stop the workpiece, or retracts downward into the through groove 16 to release the limit and stop on the workpiece.
[0048] A fourth guide mechanism is provided between the first limit stop block 98 and the fourth movable seat 97, and between the second limit stop block 901 and the fourth movable seat 97.
[0049] The first guide mechanism, the second guide mechanism, the third guide mechanism, and the fourth guide mechanism all include a guide rail 101 and a slider 102.
[0050] In summary, the key design feature of this invention lies in its ability to achieve fully automated feeding, positioning, and grooving through the combined design of the pressure plate assembly, tool holder module, and feeding device. The coordinated operation of the feeding device, workpiece pushing mechanism, limit stop mechanism, and workpiece conveying and rotating mechanism enables the automatic conveying, positioning, and rotation of the workpiece from the feeding table to the processing station, significantly improving processing efficiency and reducing manual intervention. The combined design of the feeding table, workpiece pushing mechanism, workpiece conveying and rotating mechanism, and limit stop mechanism, along with the workpiece pushing mechanism's function of moving the workpiece from the input side towards... The output side moves, allowing the workpiece conveying and rotating mechanism to transport the workpiece from the feeding table to the workpiece placement table via the output side, or to rotate the workpiece horizontally and then transport it from the feeding table to the workpiece placement table via the output side. The limiting and stopping mechanism is used to limit and stop the workpiece on both sides to restrict the workpiece to the middle area of the feeding table's conveying direction. This enables automatic workpiece pushing, adjustable posture, accurate positioning, and flexible feeding capabilities, solving problems such as workpiece offset, jamming, or low accuracy of repeated positioning, ensuring processing stability, and guaranteeing the quality and continuity of subsequent grooving processing.
