The invention relates to the field of engineering in particular to equipment for the manufacture of cylindrical workpieces, such as a bandage.

Famous line for heat treatment of bandages containing United conveyor nodes loading, calibration, heating, cooling and unloading [1]

In the famous line of the workpiece are moved in one direction only, as the design of the conveyor does not move the workpieces in both directions, and leave blanks.

But even if you return the workpiece to use these items in a production cycle, then changed its diameter billet after the media may cause damage to the mechanism, reducing the reliability of the line.

To address these shortcomings in the proposed line containing United drive conveyor download sites, calibration, heating, cooling and unloading conveyor is equipped with a carriage arranged on one level, the main rotary spring-loaded clamps and more clamps and swing arm with your finger, with the roller. Additional grips made in the form of two shoulders of levers, one of which has a groove that interacts with the finger; the download site has a copier in contact with the roller finger. Working surfaces of the grips are made with a notch.

Additional analysis of the distinctive features showed that the conveyor carriage and rotatable spring-loaded clamps known in the art, but the design of the carriage with extra grips provides movement of material in both directions. This allows use of the same positions of the line heating and cooling for calibration, and the like before calibration, and after you increased the diameter of the workpiece carriage conveyor that moves the workpiece is located at the same level symmetrically main additional grips grips made with the possibility of contact with the workpiece during reverse motion of the conveyor. This allows you to set the workpiece coaxially with the heater on technological position in the changed diameter.

Thus the proposed line heat treatment of workpieces tires has a set of essential features that provide a new effect, which consists in increasing the reliability of the system with a minimum amount of equipment.

In Fig. 1 shows a General view of the line; Fig. 2 section a-a in Fig. 1: in Fig. C cross-section B-B in Fig. 1: Fig. 4 shows additional capture and harvesting during reverse motion of the conveyor: Fig. 5 section G-G in Fig. 2: Fig. 6 section d-D in Fig. 4.

The semi-automatic line for heat treatment of workpieces band contains mounted on the base 1 (Fig. 1) the position of the load 2, the position calibration 3 in the form of press for calibration with the set stamp 4 position heat 5 and cooling 6, the unloading position 7, the conveyor 8 drive 9 (Fig. C) and the carriage 10 is barb grabs made by notch. The carriage 10 can be moved on wheels 13 (Fig. 5) along the guide rails 14 by using the chain 15, kinematically connected to the actuator 9. The main grippers 11 (Fig. 2) mounted on the shaft 16 (Fig. 6), which under the action of the spring 17 rotates the grip 11 to contact with the stop 18. A similar design to further capture differs from the basic fact that has a second shoulder 19 (Fig.4) with the groove 20. This groove moves the finger 2 (Fig. 6) with a roller 22 mounted in the lever 23, which is mounted on the shaft 24 and can be rotated by contact of the roller 22 with the Cam 25 (Fig. C). On lines 26 (Fig. 2) the loading position 2 are usually a few blanks 27, one of which must be installed in the lens position of the load formed by the protrusions 28 of the lines 26. In the work on the line is only one of the workpieces 27, which moves along the working positions of the carriage 10 in the desired process sequence and after treatment is given to the unloading position 7. When moving the workpiece 27 is lying face 29 (Fig. 5) on the lines 30, mounted on the upper surfaces of frames units. To perform technological operations (heating, calibration, cooling the workpiece is lowered from the level of transportirovanii lowering and raising the workpiece not shown). At the unloading position 7 line 32 (Fig. C) have protrusions 33 formed by reducing the thickness of the lines. These projections form the internal lens of the unloading position and contacting with the inner diameter of the workpiece 27, submitted to the unloading position, preventing its backward movement when moving the carriage 10 to the loading position.

The hotline is as follows.

In the initial position, the carriage 10 is in the unloading position 7. Additional grippers 12 are rotated in the open position due to the interaction of the roller 22 with the Cam 25. In the prism position of the load formed by the protrusions 28 lines 26, installed another piece. Actuators units of a line are in the top position. After the start of the line cycle of the carriage 10 to the unloading position is moved to the loading position. At the approach to this basic position the grippers 11, turning, passing by the workpiece, and then under the action of the spring 17 returns to its original position before contact with the stop 18, that is, the workpiece falls into the grips of the carriage 10.

Then the carriage 10 moves the workpiece from the loading position to the position of the heating, the main grippers 11 set the workpiece coaxially with the reference is Azora between the workpiece and the primary and secondary seizures. The lift position of the heating lowers the workpiece in the heating zone where it is heated workpiece. The heated billet lift raises the level of transportation. Carriage of additional grippers 12 moves the workpiece to the position of the calibration, where these grips set its alignment with the punch stamp, and then the carriage moves to a position in which guaranteed the gaps between the workpiece and the primary and secondary seizures. The press slide together with the punch descends, while moving in the radial direction Cams stamp (not shown) stretch (calibrate) the workpiece to a configured size.

After cooling the workpiece in the die slide rises, the workpiece is at the level of transportation and the carriage 10 moves the workpiece to the position of the heating, the main grippers 11 and moves the workpiece at the center position, then after the reverse of the additional conveyor grippers 12 to its working surface with a notch capture calibrated harvesting ( when the increased diameter of the workpiece) and is placed in alignment with the base elements of the lift position of the heating, after which the carriage is diverted into a position in which guaranteed the gaps between se is heated workpiece to the quenching temperature, The heated billet lift raises the level of transportation. The carriage moves the workpiece to the position of the cooling. The lift position lowers the workpiece in the tank cools the workpiece.

The cooled billet lift raises the level of transportation. The carriage moves the workpiece to the position of the heat. The lift position lowers the workpiece in the heating zone. The heated billet to a temperature high holiday lift raises the level of transportation. The carriage moves the workpiece to the position of the cooling, and then to the unloading position.

The cycle ends.

After you have installed another workpiece in the prism of a loading position and removed the stocking from the unloading position, you can begin the next cycle.

The proposed line enables calibration and heat treatment of workpieces cylindrical shape at its minimum dimensions. When this processing is increased on the outer diameter of the workpiece extra grips installed coaxially with the support elements of the lift position of the heating, which increases the reliability of the system at its minimum dimensions and minimum kolichestga, contains United drive conveyor download sites, calibration, heating, cooling and unloading, characterized in that the conveyor has a carrier located on one level, the main rotary spring-loaded clamps and more clamps and swing arms with finger having a roller, with additional grips made in the form of two shoulders of levers, one of the shoulders which has a groove that interacts with the finger, and the download site has a copier in contact with the roller finger.
