Description

The invention relates to the field of pipe rolling and pipe welding production, and more specifically to a pipe bundling line, and can be used in the production of open and closed bent profiles.

A device for packaging long lengths is known, see RF patent No. 2413670, class. B65G 57/18 stated 12/01/2009., Publ. 03/10/2011

This device contains a roller table with an adjustable emphasis, a conveyor, receiving means fixed on the portal for accumulating a number of rolled products, a lifting means with electromagnets and centralizers, as well as pockets and a vehicle with a drive. The receiving means for accumulating a number of rolled products, the lifting means with electromagnets and centralizers are located in a vertical plane above the pockets in the loading zone symmetrically to the axis of the pockets. The receiving means for accumulating a number of rolled products is made in the form of hook-shaped levers and is mounted on the portal with the possibility of rotation from the drive. The vehicle is made in the form of two parallel groups of bogies with axial displacement and driven by rack and pinion gears. Pockets mounted on each trolley with the possibility of rotation. The device does not contain a pocket for defective pipes.

A disadvantage of the known device is the narrow technological capabilities, since it can only be used in a stand-alone packaging section. It cannot be used as part of a continuous tube welding or tube rolling unit with a welding (rolling) speed of 90 ÷ 120 m / min and a minimum pipe length of 6 meters. The cycle of the arrival of pipes with a length of 6 meters is 3 ÷ 4 seconds. In the known device, after dialing a series of rolled products, many technological operations are carried out related to turning on the magnets to lift the dialed row of pipes above the receiving device, lowering the dialed row of pipes into a pocket, lifting the electromagnets after they are turned off, which take a considerable time, at least 7 seconds, which allows take the next tube after only 7 seconds.

The next disadvantage is the structural complexity of the device, high metal consumption and the complexity of manufacturing, and, as a consequence, the high cost of manufacturing and operation.

A disadvantage of the known device is the residual magnetism of the packed pipes, for the removal of which additional equipment and production area will be required.

Of the known closest in technical essence is the pipe packaging line described in RF patent No. 2004988, class. B21B 39/00, B65G 47/54, claimed 06/15/92, publ. 12/30/93

This pipe bundling line comprises a vehicle with delays, a frame with racks, pockets for defective pipes located on the frame, a device for receiving pipes and a device for accumulating and lowering the rows of pipes.

The vehicle is made in the form of a feed roller table with oblique rollers. L-shaped racks are fixed on the frame, into which pipe clamps are mounted. The device for receiving pipes is made in the form of a rack and pinion transmission with brackets having the ability to rotate and rise from its own drive. A device for accumulating and lowering rows of pipes into pockets is made in the form of a screw mechanism with a cantilever bracket. A set of pipes is carried out in pockets with a falling bottom and a folding wall, and the piping of the dialed bag is carried out at another position in pockets with a folding wall that are movable in the horizontal plane.

A disadvantage of the known design of the pipe packaging line is that it has large dimensions and metal consumption. So, for example, the width of the TESA 10-40 line is 6 meters and the metal consumption is 21 tons.

Another disadvantage of the known line is that it has many different mechanisms, which complicates its design and increases the metal consumption and the complexity of its manufacture. While maintaining high performance, a large number of mechanisms reduces the reliability of the entire line.

A further disadvantage of this packaging line is the high manufacturing and operating costs.

The objective of the present invention is to create a pipe packaging line that allows you to reduce the composition of the equipment, increase reliability, reduce dimensions, metal consumption, labor and production and operation costs while maintaining a high level of productivity.

The problem is achieved in that in the pipe bundling line containing a vehicle with delays, a frame with racks, pockets for defective pipes located on the frame, a pipe receiving device and a device for accumulating and lowering pipe rows, according to the invention, the vehicle is made in the form a drive accelerating stand and mounted on racks by means of rotary levers, rods and a drive lever transmission of idle rotary rollers with four positions of their axis of rotation, a device for Pipe acceptance is made in the form of rack-and-pinion gears placed in cylindrical rails, on the ends of which rails are fixed slip bushes and flexible spring strips, and the device for accumulating and lowering the rows of pipes is made in the form of screw transmissions installed in cylindrical rails, on the ends of the screws of which sliding bushings are fixed lowering brackets, while the device for receiving pipes and a device for accumulating and lowering the rows of pipes are installed on both sides of the racks in the cylindrical guides, combining nnyh the bottom of the split body.

Pockets for defective pipes are installed in the racks of the frame under idle rotary rollers.

A device for receiving pipes and a device for accumulating and lowering the rows of pipes are perpendicular to the plane of rolling pipes.

Radial roller wiring is fixed to the cylindrical guides of the pipe receiving device for guiding and bending the flexible spring strips.

Such a constructive implementation of the pipe bundling line allows to reduce the composition of the equipment, increase the reliability, reduce dimensions, metal consumption, labor and production and operation costs while maintaining a high level of productivity.

This is achieved due to the fact that the pipes supplied by the accelerator stand, depending on the position of the idle rotary rollers, are sent: defective to the pockets located below, suitable to the right or left of the axis of the line for packing in square bags.

The receipt of defective pipes by free fall into the pockets, and suitable pipes due to rolling cylindrical or sliding profile pipes along inclined angles of at least 25 ° to the horizontal towards the collection side into square bags minimize the overall dimensions, metal consumption and laboriousness of manufacturing this part of technological equipment.

A pipe receiving device placed in cylindrical guide roller wires that are slanted at an angle to the horizon and made in the form of a rack gear combined with a drive transmission with slip bushings and flexible spring strips rigidly fixed at the ends of the rails together with a device for accumulating and lowering the rows placed in single cylindrical guides with a device for receiving welded racks and made in the form of screw gears combined with a drive transmission with sliding bushings and a lowering bracket mi for rows of pipes make it possible to place rails and screws in one plane, create a more massive structure to absorb the shock load from rolling pipes, and also set, tie and lift to the upper position of the dialed square tube package, thus eliminating dimensional, metal-intensive and time-consuming to manufacture both stationary and mobile pockets along with mechanisms in known technical solutions.

Delays are used to accumulate 2 ÷ 3 pipes only during the process of performing technological operations - lowering the dialed row of pipes and extending to the upper parts of the flexible spring strips. This makes it possible to provide a pipe inflow rate of 3 seconds.

The constructive placement of helical gears, rack and pinion transmissions of rotary rollers and delays below the prescribed overlaps improves the service conditions of the equipment in compliance with safety requirements.

To explain the invention, a specific embodiment of the invention is provided below with reference to the accompanying drawings, in which:

The pipe bundling line comprises a vehicle with delays 1, a frame 2 with uprights 3, pockets 4 for defective pipes located on the frame 2, a device for receiving pipes and a device for accumulating and lowering the rows of pipes. The vehicle is made in the form of a drive accelerating stand 5 and mounted on racks 3 by means of rotary levers 6, rods 7 and a drive lever transmission 8 of idle rotary rollers 9 with four positions. The line contains an intermediate idle roller table 10, brackets 11 inclined for rolling and sliding the pipes, and delays 1 with levers 12, rods 13, transmission 14 with pneumatic or hydraulic actuator 15. A device for receiving pipes and a device for accumulating and lowering rows of pipes are installed on both sides from racks 3 in the provided cylindrical guides 16, 17, united in the lower part by a detachable housing 18. The device for receiving pipes is made in the form of rack and pinion gears 19 arranged in cylindrical guides 16 with a drive transmission 20. On the ends of the rails 21 are fixed sliding sleeves 22 and flexible spring strips 23. The device for accumulating and lowering the rows of pipes is made in the form of screw transmissions 24 mounted in cylindrical guides 17 with a drive transmission 25. At the ends of the screws 26, the sliding sleeves 27 and the lowering brackets 28 are fixed. cylindrical guides 16 of the device for receiving pipes fixed radial roller wiring 29 for the direction and bending of the flexible spring strips 23. Device for receiving pipes and a device for accumulating and lowering rows of pipes b are located perpendicular to the plane of rolling pipes. Pockets 4 for defective pipes are installed in racks 3 under idle rotary rollers 9. In racks 3 and cylindrical guides 16, rectangular recesses 30 are made to accommodate packing frames 31. To stop the pipes, the line is equipped with an emphasis 32. Transmissions 8, 14, 20, 25 are located below floors 33.

Line pipe packaging works as follows.

In the initial position, the arms of the delays 1 are lowered, the brackets 28 are raised to the upper initial position, and the flexible spring strip 23 lies on the bracket 28. Packing frames 31 are installed.

After cutting in a cutting device (not shown), a suitable welded pipe 34 with an accelerating stand 5 with a speed of 1.5 times the welding speed is transported along the idle rollers 9 set at an angle to the stop 32, and then stops along the brackets 11 and flexible spring bands 23, lying on the brackets 28, rolls all the way into the lateral ends of the cylindrical guides 17.

Further on the program, a set of the first row of pipes is carried out. After dialing, the levers 12 of the delay 1 are lifted, using screw gears 24 the dialed row of pipes 34 is lowered by the size of the welded pipe in height (equal to the diameter for a cylindrical pipe and the height of the profile). The drive transmission 20 is engaged and the rack and pinion transmission 19 along the radial roller wiring 29 fully extend flexible spring strips 23 from under the tubes 34, which, under their own weight, fall down on top of the dialed row of tubes. After that, the levers 12 of the delay 1 are lowered and the 2-3 pipes accumulated before that along the strips 23 are rolled up to the end into the lateral ends of the cylindrical guides 17. The second row of pipes is set. Then, similarly to the second row of pipes, the entire package of pipes is dialed. The stacked pipe bundle is tied using packaging frames 31 and a manual strapping machine (not shown). The bundled pipe package rises to the upper position and is transported by an electric bridge crane to the finished goods warehouse. In the packaging process, to fulfill the safety requirements, the levers 12 of the delay 1 are in the upper position. After receipt of the last pipe of the dialed packet, the rollers 9 rise to the horizontal position of their axis. After stopping the first pipe of the next package focusing 32, the rollers 9 are tilted to the left along the pipe. Then, similarly to the dialed and packaged pipe bundle on the right, the pipe bundle on the left is set up. Defective pipes when the rollers are lowered 9 are sent to the pockets 4 located at the bottom of the racks 3.

The proposed pipe packaging line compared to the known ones allows to reduce the composition of the equipment, increase reliability, reduce dimensions, metal consumption, labor and production and operation costs while maintaining a high level of productivity.
