- One of the analogues of the claimed invention can serve as a technological process for the production of steel pipes with a diameter of up to 1200 mm on vertical hydraulic extruding presses with an effort of 30,000 tf and 35,000 tf manufactured by Cameron (Avero D. NoCameroopertulés séméless proceedingsre // Metal Prégres, 1977 v. 3, Ns, 2, p. 52-57).
- Another analogue is the production of pipes with a diameter of up to 1400 mm on a vertical extrusion press with a force of 45,000 tf according to a later project developed in the USSR in 1980-90. (Starikov V.S. et al. Technology and tools for the production of large-diameter steel pipes by pressing // Forging and stamping. 1988, JChk 10, p. 14-17).
- the manufacture of pipes according to the above methods - analogues is characterized by the use of the direct method of pressing with the pipe flowing up and separating it from the pressure switch using a notch.
- a press stamp mounted on the table of the press remains stationary, and the container with the matrix is pushed down on it.
- pressing on a press of 45,000 tf can be carried out with highly efficient glass-based lubricants, which provide a higher surface quality of the pipes and increase the durability of the pressing tool.
- the method of manufacturing steel seamless pipes according to the patent of the Russian Federation Ns 2166394 was selected.
- the main advantage of the prototype over the aforementioned analogues is that it provides the possibility of using solid billets. It is achieved by flashing the workpiece directly on the extruding press, and the flashing operation is combined with the subsequent operation of pressing the pipe into one working cycle of the press. Thus, a combined process of flashing and pressing is carried out.
- the method is a prototype, which includes heating a workpiece, applying technological glass grease to it and a tool, and sequentially using a vertical hydraulic extruding press to flush the workpiece with a press needle (mandrel) with a preliminary pressing the workpiece in the container with a stamp, pressing by direct method with the pipe flowing out through the die downward by a movable stamp and a free (not fixed on it) press washer with the container and die stationary, and separating the pipes obtained from the pressure switch by means of pieces specially designed on the press.
- a press needle manufacturedrel
- a free (not fixed on it) press washer with the container and die stationary
- the prototype method provides a significant reduction in capital costs when creating pipe production, labor costs and operating costs (electricity, tools, equipment maintenance, etc.) in the manufacture of pipes, contributes to an increase in the share of pipes obtained by hot pressing, in general volume production of seamless steel tubes, creates favorable conditions for the construction of steel mini-mills, as well as for the organization 'on vehicles construction enterprises in their procurement departments, its own production of pipes.
- the main objective of the present invention is to provide a method for the manufacture of large-diameter seamless steel pipes, based on the combination of billet piercing and tube pressing operations in one working cycle of an extruding press and providing a reduction in capital costs during the construction of the press complex and operating costs during its operation due to simplification of the design, size and weight reduction press, • increasing the productivity of the pipe pressing process and reducing metal waste during flashing and pressing.
- the invention is intended to eliminate the largest disadvantages of all known analogues and prototype.
- the proposed method for manufacturing large-diameter steel seamless pipes involves heating a continuous cylindrical billet, applying glass lubricant to it and onto a pressing tool, successively carried out on a vertical hydraulic extruding press in one operating cycle of the flashing operation workpieces in a container with a pressing mandrel with prepressing the workpieces and pressing the pipe by direct method with the expiration metal under the action of a stamp with a press washer through the die down, as well as separating the resulting pipe from the pressure switch and releasing it from the die.
- trafit is introduced into the technological lubricant in a volume ratio with glass (1: 4) ... (1: 5).
- the preform is pressed with a press mandrel and the preform is pierced with a drawing ratio of at least 1.4.
- a press washer is used, which is rigidly fixed to the press post. Releasing pipe from the matrix after the matrix is performed on the translation product removal position displacement 'pipe pressostatkom up and separation is pressostatka produce press.
- Flashing a workpiece with a high degree of deformation allows pressing • the workpiece in the container before flashing, not with a stamp, but with a mandrel and reduces (by reducing the wall thickness of the stitched blank) the proportion of deformation attributable to subsequent pressing, and therefore. and the value of the nominal effort of the main drive of the press. All this makes it possible to carry out both firmware and pressing from this drive alone and eliminates the need for
- the support of the workpiece when it is flashed onto a monolithic stand provides a reduction in the thickness of the remaining not stitched bottom of the workpiece, and, consequently, a decrease in the volume of waste metal in the workpiece in the form of the so-called otter during subsequent cutting through the mandrel bottom of the workpiece.
- FIG. 1 (a" -
- FIG. 2 (“a” - “g”) and FIG. 3 (“a” - “c”), on. which schematically demonstrates the technological process of manufacturing pipes according to the new method on a vertical hydraulic press according to application Na 2007134334 with a priority of September 17, 2007.
- This press has a movable bed with upper and lower crossbars, a container holder with a drive located between them and a fixed crosshead.
- the guide columns of the bed are fixed on it in the corners, a movable table is installed on top, and the main drive is located below, which includes a group of working cylinders with housings mounted on a fixed crossarm and plungers connected with the lower cross member.
- the technological tool of the press consists of a container, a mandrel, a stamp and a die.
- the mandrel is mounted on the upper cross member of the movable bed.
- the stamp is installed in an additional cross-member located between this cross member and the container, equipped with an auxiliary drive for moving the stamp relative to the mandrel.
- a kit of a technological tool also contains a stand (plug) for firmware.
- the pressing matrix and the plug for firmware are located on two positions of the press table.
- An emphasis is placed on the lower cross member of the movable bed for pushing the pressed pipe out of the matrix, and a vertical groove is made in the stationary cross-beam to allow the pipe to move from the press axis to the removal position.
- FIG. 1 shows the technological transitions of the workpiece firmware (“a” - installation of the workpiece in the container, “6” - end of the workpiece unpressing, “c” - end of the firmware),
- FIG. 2 technological transitions pipe pressing (“a” - moving the die onto the axis of the press,
- the manufacture of pipes according to the method - invention is as follows.
- the mandrel 1, connected with the upper cross member 2 of the press bed, and the container 3 are in the highest position, and the press stamp 4 mounted on the additional cross member 5 of the press, with the washer 6 fixed to it, in the position in which the lower end of the press washer is located at the exit of the working cavity of the container.
- Stand 7 for firmware, placed on the table 8 occupies a position on the axis of the press.
- the heated continuous billet 9 with technological glass-graphite lubricant deposited on its side surface is fed to the axis of the press in the space between the container 'and the stand (Fig. I, pos. “A”) and mounted on this stand.
- a portion of the same lubricant is placed on the upper end of the workpiece in the form of a disk 10 with a diameter corresponding to the diameter of the mandrel. Then the container is lowered down to the stop in the stand, while the workpiece is inside the container.
- Flashing of the workpiece begins. Previously, under the action of an auxiliary drive (not shown), the ram is lowered. Then, under the action of the main drive of the press (not shown), the working course of the bed with the mandrel begins. First, the mandrel upsets (presses) the workpiece until the gaps between its side surface and the container disappear. In the process of precipitation, the workpiece is shortened. The press ram moves downward, still leaning on the workpiece with the end face of the press washer. After pressing the workpiece (Fig. 1, pos. "6"), the mandrel, continuing its downward movement, is introduced into the workpiece and flashing it, forming an inner cylindrical cavity in it (Fig. 1, pos. "c").
- the workpiece metal displaced during the firmware moves upward, towards the movement of the mandrel.
- the stamp also moves upwards, making room for an elongated workpiece.
- a partition (bottom) of small thickness At the end of the firmware in the workpiece, at its lower end, there remains a partition (bottom) of small thickness.
- the pipe is pressed.
- the container the mandrel and the stamp are shifted a small distance up.
- the table feeds to the press axis the matrix 11 installed in it with technological glass-graphite grease placed on its upper end in the form of a washer 12 with a hole (Fig. 2, item “a”).
- the container is lowered onto the matrix.
- a short stroke of the needle prosekayut bottom stitched preform to form a metal preform departing 'otter form 13 (Fig. 2, Pos. "B").
- the upper cross member of the bed, bearing the mandrel, and the additional cross member with the stamp attached to it are closed.
- the resulting pipe is removed from the press.
- the mandrel moves up and out of the pressure switch.
- the container with the pressure switch in it is lifted up to the stop against the cross member of the stamp. -
- the pressure switch supported from above fixed stamp, it is forced out of the container (Fig. 3, pos. "a”).
- the matrix with the pipe located in it moves the table to the “ pipe removal position ” , and a stand for firmware appears on the press axis.
- the stamp and the mandrel move up to the initial position, the container rises above the table to install the next workpiece (Fig. 3, - pos. "b"). Following this, the press frame begins its movement to its highest position.
- the stop 16 fixed on the lower cross member of the frame acts on the lower end of the pressed pipe, Alkylating it through the matrix upwards by the stroke of the bed ..
