Description

Technical Field

[0001] This invention belongs to the field of automotive parts processing tooling technology, and relates to an automotive internal water cutting and bending mechanism. Background Technology

[0002] Automotive interior water cutter products require a bending process, which has high quality requirements. The contour must be controlled within ±0.5mm, and there must be no obvious defects such as indentations or burrs on the surface. As the requirements for automotive interior water cutter products become more stringent, some products require that the bending point not only be freely formed, but also have an obtuse angle with specified data.

[0003] The existing bending process uses a stretching bending method, which allows the bending point to be freely shaped into a rounded corner (R). However, it still has the problem of making it difficult to form an obtuse angle with data at the bending point, indicating significant room for improvement. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by proposing an internal water-cutting and bending mechanism for automobiles.

[0005] The objective of this invention can be achieved through the following technical solution: A water-cutting and bending mechanism for an automobile, comprising:

[0006] The base is equipped with fixing blocks;

[0007] A hinge block, one end of which is hinged to the fixed block;

[0008] A movable block, which is hinged to the other end of the hinge block;

[0009] A bending drive element is provided, wherein the movable block is linked to the bending drive element, and the bending drive element can drive the movable block to move relative to the base and drive the hinge block to move, thereby bending the workpiece.

[0010] In the above-mentioned automotive interior water-cutting bending mechanism, the bending drive element is provided with a push block, the push block is in contact with the movable block, and the bending drive element can drive the push block to move, thereby pushing the movable block to move relative to the base.

[0011] In the above-mentioned automotive interior water-cutting bending mechanism, the base is further provided with a slide rail, the push block is provided with a slider, the push block is connected to the slide rail through the slider, and the bending drive element can drive the push block to move along the slide rail.

[0012] In the aforementioned automotive internal water cutting and bending mechanism, a tension spring is also included. The base is further provided with a reset seat. One end of the tension spring is connected to the movable block and the other end of the tension spring is connected to the reset seat. The tension spring can pull the movable block closer to the reset seat.

[0013] In the aforementioned automotive internal water-cutting and bending mechanism, the base is further provided with a first positioning block for contacting the movable block, the first positioning block being able to limit the maximum travel of the movable block.

[0014] In the above-mentioned automotive internal water cutting and bending mechanism, the number of hinge blocks is at least two, and each hinge block is hinged at both ends. The hinge blocks located at the beginning and end ends are respectively hinged to the fixed block and the movable block.

[0015] In the aforementioned automotive internal water-cutting bending mechanism, the base is further provided with a second positioning block for contacting the hinge block, the second positioning block limiting the maximum travel of the hinge block.

[0016] In the above-mentioned automotive internal water cutting and bending mechanism, a top material block and a top material driving element are also included. The fixed block is provided with a top material notch. The top material block is located at the top material notch and can move relative to the top material notch. The top material driving element is connected to the base. The top material block and the top material driving element are linked and connected. The top material driving element can drive the top material block to move so as to eject the workpiece.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The bending drive element can drive the movable block to move relative to the base and drive the hinge block to move, thereby bending the workpiece. The stamping bending process is used to replace the existing stretching bending process, so that the workpiece forms an obtuse angle state with data.

[0019] 2. The bending drive element can drive the push block to move, thereby pushing the movable block to move relative to the base, so that the movable block can move in a direction perpendicular to the direction pushed by the push block, ensuring that the force of the hinge block on the movable block will not affect the bending drive element.

[0020] 3. One end of the tension spring is connected to the movable block and the other end of the tension spring is connected to the reset seat. The tension spring can pull the movable block closer to the reset seat, thereby resetting the movable block when it is not subjected to the force of the bending drive element, and then driving the hinge block to reset.

[0021] 4. Setting multiple hinge blocks and hinged end to end of each hinge block is to make the workpiece form multiple anchor points, thereby making the trajectory of the workpiece in an obtuse angle state with data more accurate.

[0022] 5. The first positioning block can contact the movable block to limit the maximum travel of the movable block, and when the movable block contacts the first positioning block, the movable block is located at a predetermined position where the workpiece is to form an obtuse angle; the second positioning block can contact the hinge block to limit the maximum travel of the hinge block, and when the hinge block contacts the second positioning block, the hinge block is located at a predetermined position where the workpiece is to form an obtuse angle.
