[0066] The ultrasonic exciter 11 is placed in the exciter box 10, the exciter box 10 is provided with a sleeve on the top and bottom, and there are two force-applying devices, which are respectively connected to the exciter box 10 through two upper and lower sleeves , Two force-applying devices are set coaxially. The vacuum bag is connected with the vacuum pump 9 through the vacuum hole.

[0067] The force applying device includes a support plate 1 , a support frame and a screw rod 12 , and the screw rod 12 is provided with a rotating handle 6 , a first locking handle 5 and a second locking handle 7 .

Embodiment 2

[0069] This embodiment provides a device for improving interlayer bonding, and its structure is basically the same as that of the device for improving interlayer bonding provided in Example 1. The device in this embodiment can be placed vertically, or it can be Placed horizontally, the difference is that the vacuum unit 13 of this embodiment is a vacuum box, and there are four force-applying devices.

[0070] The exciter box 10 is provided with a sleeve respectively on the upper, lower, left, and right sides, and the screw rods 12 of the four force applying devices are respectively connected with the four sleeves. The vibrator box 10 is fixedly arranged at the center of the vacuum box.

Embodiment 3

[0072] A method for improving interlayer bonding, using the device of embodiment 1, comprising the following steps:

[0073] Step 1. Determine that the activation time of glue 17 is 50 minutes, and the maximum pressure that the insulation material layer can withstand is 0.5 MPa;

[0074] Step 2. After the thermal insulation material is bonded to the bulkhead through the glue 17 to prepare the composite material, the composite material, the force applying device and the ultrasonic exciter 11 are placed in the vacuum bag;

[0075] Step 3. According to the reading of the pressure sensor, adjust the rotating handle 6 and adjust the length of the screw. When the reading of the pressure sensor 2 is 0.35MPa, fix the first locking handle 5 and the second locking handle 7;

Abstract

The invention discloses a device for improving interlayer bonding, belongs to the technical field of interlayer bonding, and solves the problems that in the prior art, when a glue solution is in contact with a base body and an additional layer, distribution is not uniform, part of bubbles are generated, and the bonding effect is seriously influenced. The device comprises a force application deviceand an ultrasonic vibration exciter; the ultrasonic vibration exciter is connected with the force application device; the ultrasonic vibration exciter is used for releasing vibration waves to promoteinterlayer bonding; and the force application device is used for applying pressure to an outermost layer. The adhesive property of the composite material is improved.

Description

technical field [0001] The invention belongs to the technical field of interlayer bonding, in particular to a device for improving interlayer bonding. Background technique [0002] With the gradual acceleration of the flight speed of the product, the aerodynamic heating phenomenon is very serious during the flight process, and the temperature of the shell surface is very high (at a flight speed of 5M, the gas heating temperature on the outer surface can reach thousands of degrees), which is harmful to the internal equipment and itself. Structure can have a very negative impact. The heat-insulating material layer is used to change the thermophysical properties of the product surface, so as to ensure that the structural failure does not occur due to aerodynamic overheating during the flight, and at the same time, it can protect the internal equipment of the product from failure due to high temperature. [0003] The heat insulation effect and quality of the heat insulation mat...
