Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine with a positioning structure. Background Technique

[0002] A bending machine is a machine capable of bending thin plates. Its structure includes a stamping device and a base. The stamping device includes a bending knife driven by a power device. When working, a metal plate is placed on the base, and the bending knife is driven by the power device to move downward to bend the metal plate.

[0003] The existing patent (Publication No.: CN218963696U) discloses a bending machine with a positioning structure, which relates to the technical field of bending machines. It includes a machine body. The top of the inner wall of the machine body is fixedly connected to the top of a cylinder, and the output end of the cylinder is fixedly connected to the top of a bending member. This device uses two sets of pressing wheels to rotate and maintain a continuous pressing force, avoiding the risk of workpiece deformation due to excessive pressing force during traditional positioning, and can achieve positioning of workpieces with different thicknesses.

[0004] However, in the above device, since the two sets of pressing wheels are adjusted for their height positions separately and manually, multiple measurements are required during adjustment to ensure that the bottoms of the two pressing wheels are at the same height, making the adjustment cumbersome and inconvenient. Moreover, it can only bend the metal plate from the middle. When it is necessary to bend the metal plate from a position near the edge, it is difficult to perform positioning operations, resulting in the inability to bend the metal plate from other positions. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a bending machine with a positioning structure to solve the problems mentioned in the above background technique.

[0006] The technical solution of the utility model is a bending machine with a positioning structure, including a base. The top surface of the base is fixedly connected with a connecting frame. The middle of the top surface of the base is fixedly connected with a bending groove, and the bending groove is arranged inside the connecting frame. The middle of the top surface of the inner wall of the connecting frame is fixedly connected with a first cylinder, and the output end of the first cylinder is fixedly connected with a bending member. Both the left and right sides of the top surface of the inner wall of the connecting frame are fixedly connected with second cylinders. The output ends of the two second cylinders are fixedly connected with a connecting plate. A connecting block is movably sleeved on the connecting plate. The number of the connecting blocks is two and they are arranged opposite to each other left and right. The bottom surfaces of the two connecting blocks are fixedly connected with fixing plates, and the bottom surfaces of the two fixing plates are fixedly connected with pressing wheels.

[0007] In one embodiment, a third cylinder is fixedly sleeved at the bottom on the left side of the connecting frame. The output end of the third cylinder is fixedly connected to a left moving frame. A first through hole is formed on the left side of the left connecting block, and the top of the left moving frame is movably sleeved in the first through hole.

[0008] In one embodiment, a threaded hole is formed at the bottom on the right side of the connecting frame. A screw rod is threadedly sleeved in the threaded hole. The left end of the screw rod is connected to a right moving frame through a bearing. A second through hole is formed on the right side of the right connecting block, and the top of the right moving frame is movably sleeved in the second through hole. The right end face of the screw rod is fixedly connected to a handle.

[0009] In one embodiment, connecting rods are fixedly connected to the opposite faces of the left moving frame and the right moving frame and near the bottom. Limiting blocks are fixedly connected to the opposite faces of the two connecting rods.

[0010] In one embodiment, an opening groove is formed in the middle of the connecting plate, and the opening groove is adapted to the bending member.

[0011] The beneficial effects provided by the present utility model are as follows:

[0012] Through the mutual cooperation between the components, the two pressing wheels can move up and down synchronously under the traction of the connecting plate, without the need to adjust the height of one of the pressing wheels each time. The adjustment of the pressing wheels is relatively convenient. The two pressing wheels can move respectively following the left moving frame and the right moving frame, ensuring that the two pressing wheels are located above the metal part, so that they can press on the metal part after descending, and the position where the metal part is bent can be adjusted, enabling the device to bend different positions of the metal part, thereby improving the practicability of the device.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation of this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0018] In one embodiment, as Figure 1 and Figure 2 shown, a bending machine with a positioning structure includes a base 1. A connecting frame 2 is fixedly connected to the top surface of the base 1. A bending groove 3 is fixedly connected to the middle of the top surface of the base 1. The bending groove 3 is arranged inside the connecting frame 2. A first cylinder 4 is fixedly connected to the middle of the inner wall top surface of the connecting frame 2. The output end of the first cylinder 4 is fixedly connected to a bending member 5. Second cylinders 6 are fixedly connected to the left and right sides of the inner wall top surface of the connecting frame 2. The output ends of the two second cylinders 6 are fixedly connected to a connecting plate 7. A connecting block 8 is movably sleeved on the connecting plate 7. The number of the connecting blocks 8 is two and they are arranged opposite to each other left and right. Fixed plates 9 are fixedly connected to the bottom surfaces of the two connecting blocks 8. Pressing wheels 10 are fixedly connected to the bottom surfaces of the two fixed plates 9.

[0019] In order to be able to clamp and fix the metal part so that it cannot move, and be able to adjust the position of the top surface of the metal part after clamping and fixing to align with the bending part 5, so as to bend different positions of the metal part, a third cylinder 11 is fixedly sleeved at the bottom on the left side of the connecting frame 2. The output end of the third cylinder 11 is fixedly connected with a left moving frame 12. A first through hole is opened on the left side of the left connecting block 8. The top of the left moving frame 12 is movably sleeved in the first through hole. A threaded hole is opened at the bottom on the right side of the connecting frame 2. A screw rod 13 is threadedly sleeved in the threaded hole. The left end of the screw rod 13 is connected to a right moving frame 14 by a bearing. A second through hole is opened on the right side of the right connecting block 8. The top of the right moving frame 14 is movably sleeved in the second through hole. The right end face of the screw rod 13 is fixedly connected with a handle 15. Connecting rods 16 are fixedly connected to the opposite faces of the left moving frame 12 and the right moving frame 14 and near the bottom. Limiting blocks 17 are fixedly connected to the opposite faces of the two connecting rods 16. When the left moving frame 12 and the right moving frame 14 move, they can drive the pressing wheels 10 on both sides to move respectively, ensuring that the pressing wheels 10 are located above the metal part, so that they can press on the metal part after descending.

[0020] In order to enable the bending part 5 to pass through the connecting plate 7 to bend the metal part below, an opening groove 18 is opened in the middle of the connecting plate 7. The opening groove 18 is adapted to the bending part 5.

[0021] Working principle: When the utility model is used, the metal part is first placed on the bending groove 3, and the right side of the metal part is fitted with the limit block 17 on the right moving frame 14, and then the third cylinder 11 is started, and the third cylinder 11 pushes the left moving frame 12 to move right, so that the limit block 17 on the left moving frame 12 fits with the left side of the metal part, clamping and fixing the metal part, and then the second cylinder 6 is started, and the second cylinder 6 pushes the connecting plate 7 to descend, and the connecting plate 7 drives the connecting block 8 to descend, and the connecting block 8 drives the fixing plate 9 to descend, and the fixing plate 9 drives the clamping wheel 10 to descend, so that the clamping wheel 10 presses the metal part from the upper side, and the two clamping wheels 10 can move up and down synchronously through the traction of the connecting plate 7, and there is no need to adjust the height of one of the clamping wheels 10 each time, so that the adjustment of the clamping wheel 10 is more convenient, and then the first cylinder 4 pushes the bending part 5 to descend, so that the bending part 5 moves from the opening groove 18 is passed through to bend the metal part. When the bending position of the metal part needs to be adjusted, the handle 15 can be twisted before placing the metal part to rotate the screw rod 13. The rotation of the screw rod 13 will move left and right, and the screw rod 13 drives the right movable frame 14 to move. The right movable frame 14 drives the right connecting rod 16 to move left and right, and the right connecting rod 16 drives the right limit block 17 to move left and right, so that the metal part can move left and right on the bending groove 3. If the bending position of the metal part is to the left, the right movable frame 14 is moved to the right, and then the metal part is clamped and fixed. At this time, the bending part 5 is aligned with the left side of the top surface of the metal part. Conversely, if the bending position of the metal part is to the right, the right movable frame 14 is moved to the left to make the bending part 5 align with the right side of the top surface of the metal part. In this way, the bent position of the metal part can be adjusted, so that the device can bend the metal part at different positions, thereby improving the practicality of the device.

[0022] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. 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 utility model patent shall be based on the attached claims.
