Description

(54) LINE FOR APPLYING COATINGS TO LONG-DIMENSIONAL PRODUCTS BY METALIZATION METHOD

I

The invention relates to sputter coating., Known for metal coating a pipe containing a dispensing device; pre-drying chambers, oshkas and metal sprays and a product transfer mechanism, which is built into the frame with a profile stop, on which a drive station is installed, kinematically connected by means of drive chains with a pusher, equipped with an end chuck 1.

However, this line cannot ensure the stability of the pipe processing process due to the presence of a gap between the widths in the working area in which the coating is cleaned and the coating removed.

The gap between the pipes in the working area arises due to the fact that the carriage pushing the treated pipe makes a reciprocating movement, in connection with which the supply of the next pipe to the working area is possible only after the carriage returns to its original position.

The purpose of the invention is to increase productivity and reliability by eliminating the spacing between products in the work area.

The goal is achieved by the fact that the line is equipped with a working speed task node, located behind the coating chamber, and the working speed task node is made in the form of an opora roller and a product pressing mechanism to its rollers.

FIG. 1 - shows a line, obtsoga view; in fig. 2 shows the arrangement of the rollers of the live rolls and the intermediate roller supports.

The proposed line contains installed along the process: rack 1,

15 a device 2 for overloading pipes onto a receiving roller 3, rollers 4 of which are mounted at an angle oL to the axis of the pipe, chamber 5 of shot blasting CLEARING1SI, chamber 6 of metallization, intermediate roller support 7, rollers 8 of which are set at an angle ft to the axis of the pipe smaller than the angle BUT . Above the roller 7 is mounted with the possibility of vertical movement of the mechanism 9 clamp. For roller 3, 8

The support 7 has an end roller conveyor 10, the rollers 11 of which are installed at the same angle d to the pipe axis as the rollers 4. The frame of the roller table 10 has mechanisms 12 for removing pipes and feeding them to the end shelf 13. The line is equipped with an automation system. Lini works as follows. The pipes are laid on the receiving rack 1. The overload device 2 automatically carries out a piece-by-piece transfer of the pipe to the roller conveyor 3, along which it rotates progressively into the working area and is pressed by the pressing mechanism 9 to the roller 7, thereby setting the speed of the pipe to be set by the angle of installation of the rollers 8 , which provides the specified technological speed during the cleaning and application of the metal; overlapping coating in chambers 5 and 6.

After the end of the pipe passing through the rack 1, the overload device 2 automatically shifts the next pipe to the live rolls 3, which follows the previous one at some distance. Due to the fact that rollers 4 of roller table 3 are installed at a greater angle to the axis of the pipe than rollers of roller 7, each subsequent pipe catches up to the previous one before entering it into the chamber 5 of shot blasting, and in chambers 5 and 6 on the other, they move at a given technological speed, thereby not leaving free entry and exit into chambers 5 and 6.

After the tube leaves the roller 7, it moves along the roller table 10 at a speed exceeding the technological

(since the rollers And installed at a large angle to the axis of the pipe than the rollers 8 roller supports 7). When the pipe approaches the end of the rack 13, a gap forms between it and the next, allowing the removal mechanism 12 to place the pipe on the rack 13.

Thus, the stability of the treatment process in the work area is ensured.

The technical and economic advantages of the invention with respect to the known lines are as follows:

1. The line capacity is increased due to the continuous processing of pipes in the working area in automatic mode.

2. The safety equipment conditions are improved in the case of continuous processing of pipes in the working area by eliminating the emission of shot from the sealing gates of the blasting chamber, the stability of the system of technological ventilation of the pass-through blasting chambers and metallization.

3. The reliability of operation of the metallization equipment of the chamber of metallization due to the stability of its work, which excludes reusable start and stop,

4. The consumption of the material for cleaning and coating the pipes is reduced by increasing the coefficient of their use with the stability of the pipe processing process.

5. The quality of pipe processing is increased due to the stability of the technical and technological parameters of the equipment with the continuous movement of pipes in a given cycle.

6. The reliability of the system of remote control of line units increases due to the exclusion of functional units for control of operations according to the start-stop units of the working zone of the line with intermittent supply of pipes for processing.

Expected economic effect From the implementation of the invention will amount to 120 thousand rubles. in year.
