Embodiment 1

[0044] see figure 1 with figure 2, this embodiment provides a multi-cavity special-shaped double-layer thin-walled cross-section pipe rubber-plastic soft mold correction device, which is used to correct the multi-cavity special-shaped double-layer thin-walled cross-section pipe 15 to be formed into a multi-cavity special-shaped double-layer thin pipe. wall section tube. Among them, the multi-cavity special-shaped double-layer thin-walled cross-section pipe 15 to be processed can be a multi-cavity special-shaped double-layer thin-walled cross-section pipe that has been corrected for the first time, or a multi-cavity special-shaped double-layer thin-walled cross-section pipe that needs secondary processing, and formed The multi-cavity special-shaped double-layer thin-walled cross-section pipe is the corrected formed pipe and is a qualified product that meets the standards. The rectification device includes an upper bottom plate 1 , a lower bottom plate 2 , a circumferential b...

Embodiment 2

[0058] This embodiment provides a multi-cavity special-shaped double-layer thin-walled cross-section pipe rubber-plastic soft mold correction device, and the correction device is based on the embodiment 1 with additional pressure-applying equipment. Wherein, the pressing device may be the hydraulic press mentioned in Embodiment 1, or other existing equipment capable of applying pressure to the upper base plate 1 . In addition, the pressure applying device can display the size of the pressing pressure. When the pressure exceeds a threshold, the pressing device will stop applying pressure, so as to ensure that there will be no damage to the circumferential bulging mold and the soft rubber mold, and at the same time avoid damage caused by Excessive pressure will damage the multi-cavity special-shaped double-layer thin-walled cross-section tube to ensure the safety of correction.

Embodiment 3

[0060] This embodiment provides a production line for aviation multi-cavity special-shaped double-layer thin-wall cross-section pipes. The production line guarantees the production equipment and the rubber-plastic soft mold correction device for multi-cavity special-shaped double-layer thin-wall cross-section pipes in Embodiment 1 or 2. The production equipment can produce the multi-cavity special-shaped double-layer thin-wall cross-section pipe 15 to be processed (unqualified production) or the formed multi-cavity special-shaped double-layer thin-wall cross-section pipe (qualified product), and the unqualified product will be corrected by the correction device. Make it finally become a qualified product. Since the use of the straightening device can be streamlined, the straightening efficiency can be greatly improved, thereby improving the production efficiency of the entire production line, improving the yield rate of products, and reducing the burden on enterprises.

Abstract

The invention discloses a device and method for correcting a multi-cavity special-shaped double-layer thin-wall section pipe through rubber and plastic soft dies. The correcting device comprises an upper bottom plate, a lower bottom plate, a circumferential bulging die, a fixing assembly, a pressure suction assembly and a rubber sealing plate. The circumferential bulging die is used for containingthe to-be-machined multi-cavity special-shaped double-layer thin-wall section pipe and can be attached to the formed multi-cavity special-shaped double-layer thin-wall section pipe. The pressure suction assembly comprises hydraulic cylinders and rubber soft dies. The multiple hydraulic cylinders are arranged on one side of the circumferential bulging die in a surrounding mode and provide deformation restoring force for the circumferential bulging die. According to the shape of the to-be-machined multi-cavity special-shaped double-layer thin-wall section pipe, the multiple rubber soft dies aresequentially placed in the circumferential bulging die, and the to-be-machined multi-cavity special-shaped double-layer thin-wall section pipe is extruded after pressing and expansion. The multi-cavity special-shaped double-layer thin-wall section pipe is corrected through the device and method, the defects such as recesses and protrusions on the surface of the thin-wall section pipe can be overcome, manual correction is avoided, the correction time is shortened, and the correction efficiency, quality and precision are improved.

Description

technical field [0001] The invention relates to a correction device in the technical field of cross-section pipe correction, in particular to a multi-cavity special-shaped double-layer thin-wall cross-section pipe rubber-plastic soft mold correction device, and also relates to the device's multi-cavity special-shaped double-layer thin-wall cross-section pipe rubber-plastic Soft mold correction method. Background technique [0002] At present, after the multi-cavity special-shaped double-layer thin-walled cross-section tubes for aviation are extruded, due to the uneven distribution of materials, the shape and size tolerances after forming seriously do not meet the design requirements, and the curvature of the upper and lower layers is different. The traditional correction method is likely to cause larger parts. The internal stress of the material leads to the formation of protrusions and depressions on the surface of the material, which does not meet the design requirements a...
