Description

Technical Field

[0001] This utility model relates to the field of wood cutting technology, and more specifically, to a wood cutting device. Background Technology

[0002] Under current technological conditions, most cutting equipment has a relatively simple function, with a fixed cutting angle, and can only perform straight-line cutting operations. When it is necessary to process curves or arc contours, it is often necessary to rely on operators to manually adjust the workpiece angle or position, which is not only labor-intensive, but also makes it difficult to ensure the consistency of cutting accuracy.

[0003] In practice, operators are susceptible to various factors such as environmental conditions, equipment vibration, and their own fatigue, making it difficult to maintain stability during the cutting process and affecting the quality and appearance of the finished product. Furthermore, low processing efficiency and high scrap rates increase production costs, hindering the needs of large-scale production.

[0004] Furthermore, existing equipment generally lacks the ability to quickly respond to and adapt to the curvature of the wood itself. When processing wood boards of different thicknesses, the operation process is cumbersome and the adjustment time is long, making it impossible to achieve efficient and flexible continuous production.

[0005] In view of this, we propose a wood cutting arc device. Utility Model Content

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a wood cutting arc device, which has the following beneficial effects: 1. This utility model, through the cooperation of an arc-shaped guide rail and a connecting rod, allows the operator to control the cylindrical cutter to move along a predetermined trajectory by rotating the handle, achieving continuous cutting of different radii and complex arcs. The scale lines set on the connecting rod further improve positioning accuracy, avoid the errors caused by traditional manual part turning, and improve the consistency of arc cutting and the quality of finished products.

[0016] 2. This utility model uses a pressure plate, an arc-shaped guide rail for downward pressing, and a baffle for positioning to quickly fix the wooden board, reducing vibration and offset during the cutting process. An electric push rod controls the lifting and lowering of the horizontal plate, and combined with a threaded rod and slider structure, the height and position of the cutter can be flexibly adjusted to adapt to wood of different thicknesses and curvatures, saving traditional manual adjustment time, reducing operational difficulty, and facilitating continuous large-scale production.

[0025] The working principle of this utility model: First, start the electric push rod 14. The telescopic end of the electric push rod 14 drives the horizontal plate 3 to move upward. The horizontal plate 3 slides upward along the fixed rod 13. Then, place the wooden board to be cut on the support plate 2, and the wooden board abuts against the baffle 17. Adjust the position of the wooden board, and then control the telescopic end of the electric push rod 14 to reset. Then, the two pressure plates 18 press the wooden board tightly. At the same time, the lower side of the arc-shaped guide rail 4 also presses the wooden board tightly. Then push the slider 6. The slider 6 slides along the connecting rod 5. When the slider 6 reaches the designated position, rotate the hinge rod 23. The hinge rod 23 drives the sliding rod 21 to move downward through the hinge 24. The sliding rod 21 drives the pressing block 22 to press the connecting rod 5, completing the fixation of the slider 6. Then, according to the thickness of the wooden board, rotate the nut 10. The nut 10 drives the threaded rod 9 to move the sliding frame 8 downward. The sliding frame 8 drives the motor 11 to move downward. The motor 11 drives the cylindrical cutter 12 to move downward.

[0026] Then, the motor 11 is started, and the output shaft of the motor 11 drives the cylindrical cutter 12 to rotate circumferentially. Then, the operator turns the handle 15 to make the connecting rod 5 drive the slider 6 and its parts to move along the arc guide rail 4. The cylindrical cutter 12 cuts the wooden board into an arc. After the arc is cut, the motor 11 is turned off and the electric push rod 14 is started. The arc guide rail 4 and the pressure plate 18 release the pressure on the wooden board. Then, the cut wooden board is removed from the support plate 2 and a new wooden board is placed on the support plate 2 for another arc cutting.
