Description
Technical Field
[0001] The utility model belongs to the technical field of skin forming equipment, and in particular relates to a directional baffle used for roll bending forming. Background Art
[0002] With the rapid development of the aviation industry, the demand for aircraft parts continues to increase. Sheet metal skins, a crucial component of aircraft, not only protect internal components but also must meet aerodynamic design requirements to increase flight speed and meet aerodynamic structural performance requirements. Skin structures are categorized into single-curved skins, double-curved skins, and complex-shaped skins, depending on the complexity of their shapes.
[0003] During the forming process of single-curved skin, traditional roll bending machine equipment has the following problems: 1. The feeding direction is difficult to control: For parts with irregular shapes, the feeding direction is difficult to confirm accurately, which can easily lead to directional deviation during the processing.
[0004] 2. The forming curvature is unstable: When rolling for the first time, the curvature of the part often does not conform to the design theory, and needs to be adjusted repeatedly, which increases the number of forming times.
[0005] 3. Inefficiency: The process of repeatedly adjusting the curvature and direction consumes a lot of time and manpower, reduces production efficiency, and increases production costs.
[0006] Therefore, in order to improve the production efficiency and quality of single-curved skin parts, an improved equipment that can control the feeding direction and reduce the number of repeated molding times has become an urgent need. Summary of the Invention
[0007] The utility model aims to solve the above problems and provides a directional baffle for roll bending forming, which is easy to control the arc direction, shortens the forming time, improves the production efficiency and reduces the production cost.
[0008] In order to achieve the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme, which includes a bracket and a baffle body, and is characterized in that: one side of the bracket is a positioning surface that fits with the side surface of the skin rolling machine, and the positioning surface extends from the side surface of the skin rolling machine to form a reference surface, and a baffle sliding frame is provided on the reference surface; a slider is provided at the lower end of the baffle body, and the slider cooperates with the baffle sliding frame; the surface of the baffle body corresponds to the feeding area of the skin rolling machine.
[0009] As a preferred solution of the present invention, the baffle sliding frame includes two parallel fixed plates, both of which are provided with corresponding sliding grooves, a locking screw passes through the two fixed plates, and the slider between the two fixed plates is connected to a locking nut.
[0010] Furthermore, a connector is provided below the baffle body, and the slider is provided in the middle of the lower surface of the connector; the lower surface of the connector contacts the upper surfaces of the two fixing plates.
[0011] The beneficial effects of the utility model are as follows: 1. Ensure that the arc direction is perpendicular to the feeding direction: by adding a baffle body and a baffle bracket, the feeding direction of the parts is ensured to be accurate during the molding process, avoiding arc mismatch due to direction deviation.
[0012] 2. Reduce the number of forming times and improve production efficiency: By stabilizing the consistency of feeding direction and curvature, the number of repeated rolling and bending is reduced, the processing time is shortened, and production efficiency is greatly improved.
[0013] 3. Enhance the versatility and ease of operation of the equipment: The baffle body can be replaced with different shapes as needed, which is easy to operate and adaptable to parts of different shapes, with greater versatility and flexibility.
[0014] 4. Reduce production costs: reduce manpower and material input, optimize process flow, and effectively control production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The utility model includes a bracket 1 and a baffle body 5, and is characterized in that: one side of the bracket 1 is a positioning surface that fits with the side surface 2 of the skin rolling machine 3, and the positioning surface extends from the side surface 2 of the skin rolling machine 3 to form a reference surface, and a baffle sliding frame 10 is provided on the reference surface; a slider 11 is provided at the lower end of the baffle body 5, and the slider 11 cooperates with the baffle sliding frame 10; the surface of the baffle body 5 corresponds to the feeding area 4 of the skin rolling machine 3.
[0022] The bracket 1 fits with the side surface 2 of the skin rolling machine 3. Through the design of the reference surface and the baffle sliding frame 10, the baffle body 5 is ensured to be installed stably and accurately in the rolling machine, effectively ensuring the reliability of the part feeding direction.
[0023] The baffle sliding frame 10 includes two parallel fixed plates 12, each of which is provided with a corresponding sliding groove 9, a locking screw 7 passes through the two fixed plates 12, and a slider 11 between the two fixed plates 12 is connected to a locking nut 8.
[0024] The baffle sliding frame 10 can realize flexible adjustment of the position of the baffle body 5 through the cooperation of the slider 11 and the slide groove 9, as well as the locking screw 7 and the locking nut 8, adapt to skin parts of different specifications and shapes, and improve the versatility of the equipment.
[0025] A connector 6 is provided below the baffle body, and the slider 11 is provided in the middle of the lower surface of the connector 6 ; the lower surface of the connector 6 contacts the upper surfaces of the two fixing plates 12 .
[0026] The combined design of the slider 11 and the connector 6 enables the baffle body 5 to remain stable during the adjustment process, while fully fitting with the contact area of the fixed plate 12, ensuring the firmness of the baffle during operation, avoiding deviation or loosening, and improving the consistency and reliability of the molding process.
[0027] When the utility model is used, Figure 4 , for traditional roll bending machine equipment, it is difficult to confirm the feeding direction for irregular parts shown in the figure, and the direction is difficult to control during the feeding process, which can easily lead to the curvature of the part not being consistent with the theory during the first forming, and repeated forming is required. Only after repeated confirmation of the curvature can the theoretical curvature be achieved. Compared with this, the utility model solves the drawbacks of traditional forming. Figure 5 As shown, by adjusting the position of the baffle body 5, and then fixing it with the locking screw 7 and the locking nut 8, the edge of the part is attached to the baffle to complete the feeding and forming. For parts with irregular shapes, you can use Figure 5 The method adds an auxiliary ear piece to abut against the baffle body 5 for confirming the feeding direction. By using the utility model, it is possible to avoid repeated rolling and trimming time due to incorrect curvature of parts caused by direction deviation, greatly improving production efficiency and saving manpower and material resources.
