Description

Technical Field

[0001] The utility model relates to the technical field of metal bending, and particularly relates to a metal bending device. Background Art

[0002] Metal bending is a common metal processing method, which is widely used in various processes and products in the manufacturing industry. By applying force to the metal material, it is bent at a specific angle and curve to achieve the required shape and structure. During the metal bending process, a bending machine or bending die is usually used, and these devices can provide the required bending force and precise control to ensure that the metal material can be deformed according to the predetermined angle and size.

[0003] However, during the metal bending process, the metal body will have relative displacement during the downward pressing and bending process, resulting in friction between the metal body and the bending die, leading to abrasion and affecting the surface processing quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that during the metal bending process, the metal body will have relative displacement during the downward pressing and bending process, resulting in friction between the metal body and the bending die, leading to abrasion and affecting the surface processing quality, and thus provide a metal bending device.

[0005] The utility model realizes the above purpose through the following technical solutions: a metal bending device is provided, including a base and a mounting frame connected to the top of the base. A hydraulic cylinder is installed on the top surface of the mounting frame, and a pressing block is connected to the output end of the hydraulic cylinder. Lower die rods are rotatably installed on both sides of the base, and a die opening for placing and rotating with the bent metal is formed on the lower die rod. A rotating plate is detachably installed at one end of the lower die rod, and a connecting column is provided on the side surface of the base below the rotating plate, and a spring is connected between the connecting column and the rotating plate.

[0006] Further, convex platforms are respectively provided at the four corners of the base, and the lower die rods are rotatably installed on the two convex platforms on the same side, and a pressing groove is provided between the two lower die rods.

[0007] Further, a number of mutually opposite die openings are provided on the two lower die rods, and bent metal is provided on the two opposite die openings.

[0008] Further, the bent metal is a metal round bar, and the die opening is formed by profiling according to the outer shape and size of the metal round bar.

[0009] Further, the rotating plate is penetrated and installed at one end of the lower die rod, and the rotating plate is fixedly connected to the lower die rod by screws.

[0010] Furthermore, two hydraulic cylinders are installed on the top surface of the mounting bracket, and a pressing block mounting seat is jointly connected to the output ends of the two hydraulic cylinders. The pressing block is fixedly installed on the pressing block mounting seat through screws.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the lower die bar at the fixed forming position is made into a movable swing block structure. When bending the metal downwards, the lower die bar rotates together with the bent metal, and a die opening imitating the bent metal is opened on the lower die bar. Therefore, not only is the relative displacement during the bending and forming process avoided, but also the problem of surface abrasion during the bending process is solved; in addition, the base, the lower die bar, and the rotating plate are detachably connected and installed, so as to facilitate the replacement of the die and the adjustment of the bending settings. The operator can easily adjust the equipment to meet the requirements of different metal round bar sizes and bending angles.

[0013] 2. After the metal is bent and formed, the lower die bar is reset by the spring, making the entire downward pressing die more continuous; the hydraulic cylinder provides a stable power output, ensuring the consistency of the angle and bending radius of each bending, thus guaranteeing the product quality and accuracy in production.

[0023] Working principle: When this metal bending device is in use, the metal round bar 11 is placed on the mutually opposite die openings 51 of the two lower die rods 5. Then, the hydraulic cylinder 3 is started to push the pressing block 4 to press down the metal round bar 11. As the middle part of the metal round bar 11 is pressed and bent downward, the two side rods of the metal round bar 11 drive the lower die rod 5 to rotate inward towards the pressing groove 10. At this time, the rotating plate 6 also rotates and tilts along with the lower die rod 5, and the rotating plate 6 drives the spring 8 to stretch. When the metal round bar 11 is bent and formed, the hydraulic cylinder 3 drives the pressing block 4 to rise and reset. Then, the spring 8 contracts and resets, thereby pulling the rotating plate 6 and the lower die rod 5 to rotate and reset, thus completing the bending.
