Aluminum rod piece forming machining device

Abstract

The invention discloses an aluminum rod piece forming machining device, relates to the technical field of bending presses, and aims at solving the problem of poor bending and shaping effect of aluminum rod pieces. The aluminum rod piece forming machining device is characterized by comprising a lower machine rack and an upper machine rack, wherein a bending die is installed on the upper machine rack through a hydraulic rod; two main supporting assemblies are arranged at two sides, corresponding to the lower side of the bending die, of the lower machine rack; each main supporting assembly comprises a supporting base used for supporting two ends of an aluminum rod; a supporting frame is hinged to each supporting base; and the supporting frames can reversely swing towards the two sides of the bending die. An outer shaping roller and an inner shaping roller are arranged in positions, corresponding to two sides of a hinging shaft, of the upper part of each supporting frame and are used for abutting against the lower side surface of the supporting aluminum rod. An elastic supporting piece is also comprised, and is used for elastically maintaining the supporting frame. The bending forming effect on an aluminum pipe is good, so that the curve formed by bending the aluminum pipe into an arc is smoother.

Description

technical field [0001] The invention relates to the technical field of press brakes, more specifically, it relates to an aluminum rod forming processing device. Background technique [0002] In the field of mechanical processing, it is often necessary to use a press brake to bend some workpieces. At present, the principle of the press brake is usually to place the aluminum tube on the lower die, and press down through the adapted lower die. Generate pressure to shape the aluminum tube on the mold, and the upper and lower molds work together to bend the aluminum tube. However, during the molding production process, the pipe is easily trapped in the mold, and it is not easy to take out the pipe, which causes inconvenience in production. [0003] The production of some pipes only needs to bend the pipes to form an arc, so that it meets the production size requirements and does not need to form a relatively complicated structure. Therefore, in order to increase the convenience ...

However, during the molding production process, the pipe is easy to sink into the mold, and it is not easy to take out the pipe, which causes inconvenience in production

[0003]The production of some pipes only needs to bend the pipes to form an arc to meet the production size requirements, and does not need to form a relatively complicated structure, so in order to increase Convenience in production and use, using an upper mold with an arc structure; only two support blocks are used for support at the lower part, and during the pressing process, the middle part of the pipe is pressed through the downwardly protruding arc upper mold, because there is no support in the middle of the pipe The support of the block is used to bend the pipe. After the upper die is fully pressed down, the bent pipe can be obtained. Compared with the upper and lower dies, the operation is more convenient; but in the forming process, the bending force on the pipe Only in the middle position of the pipe, the middle position can meet the bending requirements, but the forming effect of the two ends of the pipe is poor, especially at the two ends of the support block. When pressing down, the two ends of the pipe cannot be completely fitted under the upper mold Surface, resulting in poor bending and forming effect at this part, affecting the bending and forming quality of the pipe
