Abstract
A kind of internally coated spraying method of tubing coupling screw thread, implemented by a set of spray equipment, the spray equipment includes steel pipe, first cover for seat, second cover for seat, multiple connection sleeve pipes and thread protecting cap, the first cover for seat is first put into before spraying into steel pipe, it is then placed in first box cupling, place into first connection sleeve pipe, place into second box cupling, second connection sleeve pipe, by that analogy, it is finally putting into the second cover for seat, thread protecting cap is covered outside steel pipe, then spraying gun barrel is sent into steel pipe, start spraying equipment to be sprayed, spraying takes out box cupling and is put into continuous oven and toasted one by one after terminating.The present invention is greatly reduced the working strength of employee, improves production efficiency as a result of the method for multiple box cuplings while continuous spray；And spraying area and accurate size, suitable for the intraoral coating spraying of tubing coupling silk of various sizes.
Description
Technical field
The present invention relates to a kind of spraying method, more particularly to a kind of internally coated spraying method of tubing coupling screw thread.
Background technology
Tubing coupling screw thread undercoating in spraying, it is necessary to box cupling removed into hand spray one by one, wasting manpower and material resources,
It largely have impact on the production efficiency of product.If not removing direct spraying, heating link again can by box cupling and
Thread compound baking between body is dry, without lubrication, can not remove box cupling using also resulting in get rusty for a long time.
Therefore the spraying of screw threads of coupler undercoating turns into the weak link of undercoating production line.
The content of the invention
The purpose of the present invention, exactly in order to solve the above-mentioned problems of the prior art, there is provided a kind of tubing coupling silk
Detain internally coated spraying method.
In order to achieve the above object, present invention employs following technical scheme：A kind of tubing coupling screw thread is internally coated
Spraying method, implemented by a set of spray equipment, the spray equipment include steel pipe, the first cover for seat, the second cover for seat,
Multiple connection sleeve pipes and thread protecting cap, the first cover for seat is first put into before spraying into steel pipe, is then placed in first box cupling,
First connection sleeve pipe is placed into, second box cupling, second connection sleeve pipe is placed into, by that analogy, finally puts
Enter the second cover for seat, thread protecting cap is covered outside steel pipe, then steel pipe is placed horizontally on stand, promote spraying dolly
Move ahead and spraying gun barrel is sent into steel pipe, start spraying equipment, allow spraying dolly to retreat and sprayed, after spraying terminates
Taking-up box cupling is put into continuous oven and toasted one by one.
The internal diameter of the steel pipe is adapted to box cupling, and one end of steel pipe is opening, and provided with for connecting the outer of thread protecting cap
Screw thread；The other end is provided with the interior step for being used for placing the first cover for seat.
First cover for seat and the second cover for seat are respectively provided with the short tube of insertion box cupling.
Be provided with bulge loop among the connection sleeve pipe, bulge loop both ends form two for inserting two adjacent box cuplings respectively
Short tube.
After cover for seat or connection sleeve pipe are inserted in box cupling both ends respectively, the wide spraying areas of 50mm are left at middle part.
Compared with prior art, the present invention has advantages below：
1) as a result of the method for multiple box cuplings continuous spray simultaneously, the working strength of employee is greatly reduced,
Improve production efficiency；
2) spraying area and accurate size, suitable for the intraoral coating spraying of tubing coupling silk of various sizes, and carry
The high production efficiency and first-time qualification rate of product.

Embodiment
Referring to Fig. 1, coordinate the spray equipment used referring to Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, the present invention,
Including steel pipe 1, the first cover for seat 2, the second cover for seat 5, multiple connection sleeve pipes 4 and thread protecting cap 6.
Referring to Fig. 2, the internal diameter of the steel pipe 1 in the present invention is adapted to box cupling 3, and one end 11 of steel pipe is opening,
And provided with the external screw thread for being used to connect thread protecting cap；The other end 12 is provided with the interior step for being used for placing the first cover for seat.
Referring to Fig. 3, Fig. 6, the first cover for seat 2 and the second cover for seat 5 in the present invention are respectively provided with insertion box cupling
Short tube.
Referring to Fig. 5, bulge loop 41 is provided among the connection sleeve pipe 4 in the present invention, bulge loop both ends form two use respectively
In the short tube 42,43 for inserting two adjacent box cuplings.
After cover for seat or connection sleeve pipe are inserted in box cupling both ends respectively, the wide spraying areas of 50mm are left at middle part.
The internally coated spraying method of tubing coupling screw thread of the present invention is implemented by above-mentioned spray equipment, before spraying first
The first cover for seat is put into steel pipe, is then placed in first box cupling, places into first connection sleeve pipe, places into
Two box cuplings, second connection sleeve pipe, by that analogy, are finally putting into the second cover for seat, thread protecting cap are covered outside steel pipe,
Then steel pipe is placed horizontally on stand, promotes spraying Plantago minuta to be about to spray gun barrel feeding steel pipe, start spraying
Equipment, allow spraying dolly to retreat and sprayed, spraying takes out box cupling and be put into continuous oven and toasted one by one after terminating.
Highly preferred embodiment of the present invention is that the length of steel pipe can just accommodate 7 box cuplings and 6 connection sleeve pipes.
