Embodiment 1

[0038] see figure 1 , a ballistic product anti-overload potting process, comprising the following steps:

[0039] a. First use silicone rubber to seal the gaps on the bomb-loaded products. After the gaps are filled, start to prepare epoxy resin AB-type potting glue. The preparation ratio of epoxy resin AB-type potting glue is A-type glue: B-type glue is 2:1, pour B-type glue into the container and weigh, then pour A-type glue into the container according to the proportion, and stir at a uniform speed;

[0040] b. Take out the pushing and compressing part of the syringe, pour the prepared epoxy resin AB type potting compound into the syringe, and then put the pushing and compressing part into the syringe;

[0041] c. Fix the bomb-loaded product on the vibrator, make the glue filling hole of the bomb-loaded product face up, the needle of the syringe extends into the inside of the bomb-loaded product from the glue filling hole, turn on the vibrator, and then pour epoxy resin AB ...

Embodiment 2

[0045] see figure 1 , on the basis of Example 1, further, preferably:

[0046] In the step a, the silicone rubber is 704 silicone rubber, and the use of silicone rubber to seal the gaps on the missile-borne products specifically refers to using a sealing rod to evenly apply 704 silicone rubber to the gaps of the missile-borne products.

[0047] In the step a, the uniform directional stirring specifically refers to stirring clockwise at a stirring speed of 150 r / min, and the stirring time is 3 min.

[0048] In the step a, the viscosity of type A glue is 500cps, and the viscosity of type B glue is 400cps.

[0049] In the step c, the epoxy resin AB-type potting glue is injected into the missile-borne product at a uniform speed, specifically at a speed of 7ml / min.

[0050]This embodiment is a preferred implementation manner, which can effectively prevent the leakage of the potting compound, and is beneficial to improve the potting quality.

Embodiment 3

[0052] see figure 1 , on the basis of Example 1, further, preferably:

[0053] In the step a, the silicone rubber is 704 silicone rubber, and the use of silicone rubber to seal the gaps on the missile-borne products specifically refers to using a sealing rod to evenly apply 704 silicone rubber to the gaps of the missile-borne products. Uniform directional stirring specifically refers to stirring clockwise at a stirring speed of 200 r / min, and the stirring time is 4 minutes. The viscosity of type A glue is 600cps, and the viscosity of type B glue is 500cps.

[0054] In the step c, the epoxy resin AB-type potting compound is injected into the missile-borne product at a uniform speed, which specifically refers to injection at a speed of 9ml / min.

[0055] In the step d, moving to a high-temperature box means keeping the temperature of the high-temperature box at 40° C. for 6 hours.

[0056] This embodiment is yet another preferred implementation mode, which can completely solid...

Abstract

The invention discloses an anti-overload potting process for a missile-borne product, and belongs to the technical field of missile-borne. The anti-overload potting process is characterized by comprising the following steps that a, caulking is carried out on a gap on the missile-borne product by using silicon rubber, and preparation of an epoxy resin AB type potting adhesive is started after the gap is caulked; b, the prepared epoxy resin AB type potting adhesive is poured into a needle cylinder; c, the missile-borne product is fixed on a vibration meter, the vibration meter is started, and the epoxy resin AB type potting adhesive is injected to the interior of the missile-borne product at a constant speed; and d, after the potting amount and the potting state are verified to meet the requirements, the missile-borne product is taken down from the vibration meter and transferred into a high-temperature box for placement, the missile-borne product is taken out after the epoxy resin AB type potting adhesive is completely solidified and hardened, finally, the silicone rubber for caulking the missile-borne product is cleaned, and the potting of the missile-borne product is completed. According to the anti-overload potting process, the whole potting operation is simple and easy to implement, the potting efficiency can be effectively improved, the potting uniformity can be kept in the potting process, and the potting quality and the potting effect are improved.

Description

technical field [0001] The invention relates to the field of ballistic technology, in particular to an anti-overload potting technology for ballistic products. Background technique [0002] With the rapid development of electronic technology, missile-borne products, such as missiles and artillery shells, are also rapidly developing towards modernization and informationization. In addition to the propulsion and explosion parts of missile-borne products, the information-based seeker also occupies an important position. The information-based seeker is mainly composed of an antenna module, a control module, a radio frequency module, a power supply module and a signal processing module. Missile-borne products need to withstand extremely high overload loads at the moment of launch. In order not to be damaged during the impact, it is necessary to protect the internal connection cables, electronic devices and electronic circuits of the seeker against overloading. A more effective me...
