Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tooling for the paving and forming of composite material radomes, and particularly to a lean tooling for the auxiliary forming of composite material radomes. Background Art

[0002] During the molding process, when the mold is undergoing the paving process, the mold must be removed from the flip tooling and placed on the ground with pads for operation. The load-bearing belt is laid in a ring-shaped paving area, and the number of paving layers of the load-bearing belt is large. The paving requires that the prepreg and the bottom surface of the foam fit tightly, and the operation requires the cooperation of multiple people at the same time.

[0003] During the paving operation, each layer of the load-bearing belt is laid in blocks, and a work ladder is used to assist in the paving operation in the area where each prepreg is laid. The paving area of the prepreg is longer than the standing paving range of the work ladder, so the position of the work ladder needs to be adjusted intermittently for operation, which increases labor intensity and makes it difficult to meet the requirements of improving production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a lean tooling for auxiliary molding of composite material radome, which reduces ineffective working time and improves production efficiency.

[0005] Technical solution: A lean tooling for auxiliary molding of composite material radomes, including 4 fan-shaped toolings, each of which is provided with a standing platform 40 to 60 mm above the ground, and a working platform 70 to 90 mm above the standing platform; after the fan-shaped toolings are spliced in sequence, the standing platforms form a circular corridor in sequence.

[0006] In the aforementioned lean tooling for auxiliary molding of composite material radome, the standing platform is 70mm to 80mm wide.

[0007] In the aforementioned lean tooling for auxiliary molding of composite material radome, a wheel assembly with a brake is provided at the bottom of the fan-shaped tooling.

[0008] In the aforementioned lean tooling for auxiliary molding of composite material radomes, the working platform is a foldable structure. In the storage state, the working platform is folded and perpendicular to the ground.

[0009] In the aforementioned lean tooling for auxiliary molding of composite material radomes, the outer side of the fan-shaped tooling standing platform is provided with a fence, and the inner side is an open structure.

[0010] In the aforementioned lean tooling for auxiliary molding of composite material radome, the working platform is folded and connected to the outside of the top of the fence.

[0011] Beneficial Effects: The utility model provides an auxiliary tooling that facilitates the laying and forming of composite cover bodies in conjunction with the forming tooling, meeting the requirements of multiple people working together simultaneously. It eliminates the unnecessary work of the operator constantly adjusting the work ladder during the laying process, and the repetitive operation of getting the prepreg up and down the work ladder after each layer of prepreg is laid. This reduces labor intensity, reduces ineffective work time, and improves production efficiency. Compared to the previous load-bearing belt laying process that required 12 hours of operation time and labor intensity by 4 people, it can now be completed by 6 hours by 4 people, improving work efficiency by 50%. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 This is a schematic structural diagram of the fan-shaped tooling of the utility model;

[0013] Figure 2 It is a schematic diagram of the structure after the fan-shaped tooling is assembled. DETAILED DESCRIPTION

[0014] Example 1. A lean tooling for auxiliary molding of composite radome, see Figure 1-Figure 2 The system consists of four fan-shaped fixtures, each equipped with a standing platform 1 40 to 60 mm above the ground and a working platform 2 170 to 90 mm above the standing platform. After the fan-shaped fixtures are connected, the standing platforms 1 form a circular corridor. The circular corridor replaces the original work ladder, raising the height of the paving position. Operators can move freely in a circular manner on the circular corridor, eliminating the unnecessary work of constantly adjusting the work ladder during the paving process.

[0015] The aforementioned standing platform 1 is 70mm to 80mm wide.

[0016] The bottom of the aforementioned fan-shaped tooling is provided with a wheel assembly 3 with a brake. The fan-shaped tooling is designed with wheels to facilitate the movement of the tooling. The wheels are provided with a brake device to prevent the fan-shaped tooling from shifting when combined for operation, causing gaps between the platforms.

[0017] The aforementioned work platform 2 is a foldable structure. In the storage state, the work platform 2 is folded and perpendicular to the ground. When performing the paving operation, the work platform 2 is propped up and the prepreg to be paved is placed on the work platform 2. This avoids the repeated operation steps of going up and down the work ladder to take the prepreg after completing the paving of a layer of prepreg, reducing ineffective work time and improving production efficiency. The work platform 2 can be folded up when not in use, which is convenient for storing and placing work tools.

[0018] The outer side of the aforementioned fan-shaped tool standing platform 1 is provided with a fence 4, and the inner side is an open structure.

[0019] The aforementioned working platform 2 is foldably connected to the outer side of the top of the fence 4 .
