Abstract
The invention relates to a communication device and particularly relates to a method for producing a double-waterproof-groove optical cable cross-connecting box. The method comprises the steps of placing a side plate on a specific bending and drawing composite die to bend the U-shaped side plate and draw waterproof grooves on two end faces of the U-shaped side plate in one step; forming waterproof grooves in one side face of a top plate and one side face of a bottom plate in a milling mode respectively; welding the side plate and the top plate together, and welding the side plate and the bottom plate together; placing a box door on a drawing die to form protruding grooves which are matched with shapes of the waterproof grooves of a box body in a drawing mode; spraying waterproof coatings onto an inner cavity of the box body and the inner wall of the box door; performing mechanical strength tests, assembly tests, airtightness tests, combustion performance tests and grounding conductive performance tests on the optical cable cross-connecting box; and performing alcohol solvent resistance tests on the waterproof coating of the inner cavity of the box body. According to the method, the production cost is low, the waterproof effect of products is good, the mechanical performance is high, and the product quality is guaranteed.
Description
Technical field
The present invention relates to communication apparatus, relate to the production method of a kind of pair of capillary groove fiber cable cross connection box specifically.
Background technology
Fiber cable cross connection box is for outdoor optical cable Access Network backbone optical cable and optical distribution cable node sections infrared optical fiber distribution plant, realizes welding at the bottom of straight-through, the dish storage of optical fiber and the optical fiber, scheduling feature, can be used for outdoorly landing, built on stilts mounting means.
Fiber cable cross connection box is mounted in outdoor optical cable connection device, can support weather and the bad working environment that is subjected to drastic change exactly to its most basic requirement, need have characteristics such as waterproof airsetting knot, water proof and dust proof, shock resistance damage.Therefore, had relatively high expectations in aspects such as waterproof, protection against the tide, dustproof, anticollision infringement.
And fiber cable cross connection box waterproof type in the market has two kinds, and a kind of is to adopt single waterproof slot type casing; Another kind is to adopt no waterproof slot type casing, cooperates the sealing strip on the chamber door to reach waterproof effect.But these two kinds of waterproof types are being that waterproof effect is not fine in the practical application.And these two kinds of fiber cable cross connection boxes are not tight owing to cooperating between casing and the chamber door, so shock resistance is also relatively poor relatively.
Summary of the invention
For solving the problem that prior art exists, the invention provides the production method of a kind of pair of capillary groove fiber cable cross connection box.
The present invention is achieved through the following technical solutions: the present invention includes:
A is placed on side plate after the size that numerical control press is worked into regulation, side plate is placed on the specific bending stretching composite die one-shot forming is carried out in the bending of U-shaped side plate and the stretching of the capillary groove on the women's head-ornaments of U-shaped side plate two ends;
B is placed on CNC milling machine respectively with top board, base plate and is washed till given size, and mills out capillary groove respectively in a side of top board, base plate;
The side plate that c makes in the A step is placed on mould and stamps out shutter;
D to after connecting, welds together the capillary groove on the side plate and base plate and waterproof roofing groove respectively with side plate and top board, side plate and base plate;
Depth of parallelism squareness tolerance between e check side plate and base plate, side plate and top board, each face of side plate will be asked for up to standard;
F is installed in spacer member, the riveted joint of supporting plate spare of box house in the casing chamber;
G is placed on chamber door the tongue of stretched and casing capillary groove form fit on the drawing die;
H installs chamber door at casing, and guarantees that the capillary groove on the casing and the tongue on the chamber door closely cooperate when chamber door is closed;
I is to cabinets cavity, chamber door inner-wall spraying waterproof coating;
The fiber cable cross connection box of j carries out mechanical strength check, assembling check, Leakage Test, combustibility check and the check of ground connection electric conductivity.
The waterproof coating of the cabinets cavity of k carries out the check of the anti-alcohol flux of coating.
The invention has the beneficial effects as follows: the present invention is provided with two capillary groove structures at side plate, base plate and top board; Adopt accurate welding fabrication between side plate one-shot forming, side plate and base plate and the top board, both guaranteed the planform of capillary groove, reduced one-tenth again and produced cost; At cabinets cavity, chamber door inner-wall spraying waterproof coating, further guaranteed the waterproof effect of fiber cable cross connection box; Fiber cable cross connection box is carried out service check guaranteed product quality.
The specific embodiment
The present invention includes:
A is placed on side plate after the size that numerical control press is worked into regulation, side plate is placed on the specific bending stretching composite die one-shot forming is carried out in the bending of U-shaped side plate and the stretching of the capillary groove on the women's head-ornaments of U-shaped side plate two ends.
B is placed on CNC milling machine respectively with top board, base plate and is washed till given size, and mills out capillary groove respectively in a side of top board, base plate.
The side plate that c makes in a step is placed on mould and stamps out shutter.
D to after connecting, welds together the capillary groove on the side plate and base plate and waterproof roofing groove respectively with side plate and top board, side plate and base plate; Solder joint length 8～12mm, the distance 200 ± 20mm between two solder joints, the spot welding spacing is less than 50mm, and spot size is less than φ 5, and solder joint arranges that evenly depth of cup is no more than firm and hard border thickness 15% on the solder joint, and can not leave tangible crator after the welding.After the welding, other non-welding position has not allowed by welding slag, arc damage phenomenon, and surperficial welding slag, splash need be removed totally.After the welding, outer surface should not have defectives such as slag inclusion, pore, overlap, projection, depression, and the defective of inner surface should not obviously reach does not influence assembling.Strength member such as casing, chamber door also should be removed post-weld stress, prevents distortion.It is Ra3.2～6.3 that welding back outer surface should polish postwelding polishing roughness, and the part that sprays paint is Ra6.3～12.5.
Depth of parallelism squareness tolerance between e check side plate and base plate, side plate and top board, each face of side plate will be asked for up to standard; The flatness of top board, base plate and side plate is 1mm; The perpendicularity of side plate and base plate is 1mm; Top board and the base plate depth of parallelism are 0.5mm.
F is installed in spacer member, the riveted joint of supporting plate spare of box house in the casing chamber; Spacer member, supporting plate spare are packed into behind the casing, should vertically rectify, and spacer member, supporting plate spare side and tank floor perpendicularity are 0.5mm, and the depth of parallelism of spacer member, supporting plate spare bottom surface and tank floor is 0.5mm.
G is placed on chamber door the tongue of stretched and casing capillary groove form fit on the drawing die.
H installs chamber door at casing, and guarantees that the capillary groove on the casing and the tongue on the chamber door closely cooperate when chamber door is closed.
I is to cabinets cavity, chamber door inner-wall spraying waterproof coating.
The fiber cable cross connection box of j carries out mechanical strength check, assembling check, Leakage Test, combustibility check and the check of ground connection electric conductivity.
