[0002] In the field of metal processing, bending metal workpieces is a common and important process operation, widely used in many industries such as automobile manufacturing, mechanical processing, electronic equipment production, building decoration, etc. With the continuous development of various industries, higher requirements are put forward for the bending precision, efficiency and processing diversity of metal workpieces.

[0003] Traditional metal processing bending methods have many limitations. Some early bending equipment has simple structure and relies on manual operation, which not only has high labor intensity, but also cannot guarantee the bending precision, and cannot meet the requirements of modern industrial production for high precision. For example, in some small processing plants, workers may use simple manual bending tools to bend metal plates, and the error of bending angle and size is large, which leads to uneven product quality and high scrap rate.

[0004] In addition, some more complex bending equipment has certain degree of automation, but has single function and poor adaptability. They can only bend workpieces of specific shape and size, and cannot meet the diversified production demand. When different specifications of workpieces need to be processed, a large amount of adjustment and replacement of molds may be needed, which not only consumes time and manpower, but also reduces production efficiency.

[0005] At the same time, the existing part of bending device is not stable enough when fixing workpiece, and the workpiece is easy to shift during bending process, which not only affects the bending quality, but also may cause safety accidents. Moreover, the operation process of these devices is not convenient enough, and the operators need to have high professional skills and experience to operate skillfully, which also limits the improvement of production efficiency and the popularization and application of technology.

[0028] Refer to the drawings Figs. 1-4 A bending device for metal machining, comprising a rack 1, two guide rails 2 are arranged in parallel on the rack 1, a material placing table 3 and two movable tables 5 are arranged on the guide rails 2 through sliding blocks 7, the two movable tables 5 are arranged on the two sides of the material placing table 3 respectively, a fixing mechanism 4 is arranged on the material placing table 3, a bending mechanism 6 is arranged on the movable table 5, the fixing mechanism 4 is used for clamping and fixing the workpiece, and the bending mechanism 6 is used for bending the workpiece.

[0029] The fixing mechanism 4 comprises lifting assemblies 8 symmetrically arranged on the upper and lower ends of the material placing table 3 and clamping blocks 41 arranged on the output ends of the lifting assemblies 8, and the material placing table 3 is provided with a first avoiding groove 31 for avoiding the clamping blocks 41.

[0030] The bending mechanism 6 comprises lifting assemblies 8 arranged above the movable table 5 and bending heads 61 arranged on the output ends of the lifting assemblies 8, and the movable table 5 is provided with a second avoiding groove 51 for avoiding the bending heads 61 and the workpiece.

[0031] The lifting assembly 8 comprises a mounting plate 81, a support shaft 82 is arranged between the mounting plate 81 and the material placing table 3 or the movable table 5, a hydraulic cylinder 83 is arranged on the mounting plate 81, a lifting block 84 is arranged on the output end of the hydraulic cylinder 83, a mounting seat 86 is arranged on the lifting block 84, and the mounting seat 86 is used for mounting the clamping block 41 or the bending head 61. The support shaft 82 is provided with four support shafts 82, and the four support shafts 82 are arranged at four corners of the mounting plate 81 respectively. A guide sleeve 85 is arranged at four corners of the lifting block 84, and the guide sleeve 85 is slidably arranged on the support shaft 82.

[0032] Working principle:

[0033] Workpiece feeding and fixing: the workpiece to be bent is placed on the material placing table 3. The lifting assembly 8 of the fixing mechanism 4 is started, at this time the hydraulic cylinder 83 on the mounting plate 81 works and pushes the lifting block 84 to move along the support shaft 82. Since the guide sleeves 85 at the four corners of the lifting block 84 slide up and down on the support shaft 82, the stability of the movement of the lifting block 84 is ensured. With the lifting and lowering of the lifting block 84, the clamping block 41 mounted on the mounting seat 86 thereof also rises and falls, and through the first avoiding slot 31 on the material placing table 3, the workpiece is tightly clamped and fixed on the material placing table 3. The lifting assembly 8 at both ends of the material placing table 3 drives the clamping block 41 to apply pressure from the upper and lower directions of the workpiece, so that the workpiece is tightly fixed in the middle. This way can form all-around constraint on the workpiece, so that it is difficult to displace in all directions, and the stability is extremely high. The force distribution of the upper and lower clamping is relatively uniform, which can effectively avoid deformation or damage of the workpiece caused by uneven local stress.

[0034] Workpiece bending: after the workpiece is fixed, the movable table 5 is controlled to move on the guide rail 2 through the sliding block 7, and is adjusted to a suitable position, so that the bending head 61 is aligned with the part of the workpiece to be bent. Then the lifting assembly 8 of the bending mechanism 6 is started, and the hydraulic cylinder 83 on the mounting plate 81 pushes the lifting block 84 to move downward along the support shaft 82, and the bending head 61 mounted on the mounting seat 86 of the lifting block 84 also descends, so that the workpiece is bent through the second avoiding slot 51 on the movable table 5. After the bending is completed, the hydraulic cylinder 83 drives the lifting block 84 to rise, so that the bending head 61 is reset. Then the movable table 5 moves back to the initial position on the guide rail 2 through the sliding block 7.

[0035] Workpiece unloading: the lifting assembly 8 of the fixing mechanism 4 is actuated again, the hydraulic cylinder 83 drives the lifting block 84 to rise, so that the clamping block 41 rises and releases the clamping of the workpiece, at this time the workpiece after bending can be taken off from the material placing table 3.

[0036] The above-described embodiments only express certain implementation manners of the present application, and the description is relatively specific and detailed, but should not be understood as a limitation on the scope of the present application; it should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application patent should be subject to the appended claims.
