Description

Technical Field

[0001] The utility model mainly relates to the technical field of mechanical processing equipment, in particular to a metal plate bending machine. Background Art

[0002] A sheet metal press brake is a machine specially used for processing and forming sheet metal. Its working principle is to bend and deform the sheet metal on the die by applying external force, such as a hydraulic or electric drive system, to obtain the desired shape.

[0021] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0025] See attached Figure 1-3 A metal plate bending machine comprises a processing table 1, a first curved plate 2 driven to move in a horizontal direction is arranged on the top of the processing table 1, a second curved plate 3 is arranged in the moving direction of the first curved plate 2, and the inner curvature of the second curved plate 3 is the same as the outer curvature of the first curved plate 2;

[0026] A completely penetrating guide hole 301 is provided on the side wall of the second arc-shaped plate 3 , in which a push rod 4 is slidably installed. A first spring 6 is provided on the push rod 4 , and the push rod 4 is also slidably connected to a first connecting block 5 fixedly installed on the top of the processing table 1 .

[0027] In this embodiment, the plate is placed on one side of the inner arc of the second curved plate 3, and then the first curved plate 2 is driven to approach the second curved plate 3, squeezing the plate between the first curved plate 2 and the second curved plate 3 until one side of the plate fits with the outer arc of the first curved plate 2, and the other side fits with the inner arc of the second curved plate 3. During the process, the plate will push the ejector rod 4 and drive the first spring 6 to stretch. When the first curved plate 2 is driven to recover, the rebound of the first spring 6 will drive the ejector rod 4 to recover, and the plate that is in contact with the inner arc of the second curved plate 3 will be ejected, so that the bent plate can be directly obtained, which reduces labor costs and improves overall work efficiency.

[0028] A fixed plate 7 is fixedly installed on the top of the processing table 1, and a slidably installed first guide slide rod 8 and a rotatably installed screw rod 10 are extended in the horizontal direction on the fixed plate 7. There are two first guide slide rods 8, which are respectively located on both sides of the screw rod 10. The ends of the two first guide slide rods 8 are fixedly installed with mounting plates 9. The mounting plates 9 are arranged on the first arc plate 2 and are threadedly connected to the screw rod 10.

[0029] In this embodiment, after the screw rod 10 rotates, the mounting plate 9 threadably connected thereto cooperates with the sliding of the first guide rod 8 on the fixed plate 7 to drive the mounting plate 9 to move in the horizontal direction, and the first arc plate 2 keeps moving synchronously.

[0030] The processing table 1 and the second arc-shaped plate 3 , as well as the mounting plate 9 and the first arc-shaped plate 2 are connected by screws.

[0031] In this embodiment, the first curved plate 2 and the second curved plate 3 are both detachable, so that different curvature specifications can be replaced for performing different types of complete processing on the plate.

[0032] A rotating bracket 11 is provided on the processing table 1 , and a worm 12 is provided on the rotating bracket 11 . A handle 13 is mounted on the end of the worm 12 , and the worm 12 meshes with a worm wheel 14 fixedly mounted on the screw rod 10 .

[0033] In this embodiment, after holding the handle 13 and rotating the worm 12, the worm wheel 14 meshing therewith can be driven to rotate, and the screw 10 keeps rotating synchronously. Through the above transmission, it can be ensured that the screw 10 has a higher torque.

[0034] A limiting mechanism 15 is arranged on the processing table 1, and the limiting mechanism 15 includes a fixed second connecting block 1501. There are two second connecting blocks 1501, which are respectively located on both sides of the second arc-shaped plate 3. Relatively distributed second guide slide rods 1502 are slidably installed on the two second connecting blocks 1501. Second springs 1503 are arranged on the two second guide slide rods 1502, and limiting plates 1504 are fixedly installed at the opposite ends.

[0035] In this embodiment, the second guide slide rod 1502 is driven by the elastic force of the second spring 1503 to push the limiting plate 1504 at its end against the side wall of the plate, thereby limiting the plate to the middle to ensure the accuracy of subsequent bending processing and prevent thinner plates from falling down.

[0036] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
