Description

The invention relates to equipment for non-ferrous metallurgy, in particular to equipment for the production of titanium sponge.

A known installation for extracting a block of spongy titanium from a retort reactor (copyright certificate No. 203910, published 09.10.1967), including a drive made in the form of a horizontal hydraulic cylinder mounted on a support element. The hydraulic cylinder is designed to push the block of sponge titanium from the retort (reactor), which is placed on the machine, which serves as a supporting element. The installation also contains means for cutting the skull, located next to the machine on the opposite side of the support element with a hydraulic cylinder.

This installation is made with large dimensions due to the presence of a hydraulic cylinder with a large stroke, necessary to push the block of sponge titanium from the retort. Therefore, the layout of the elements characterizes the known installation as extended due to the presence of a hydraulic cylinder with a rod of considerable length.

A well-known press for extracting sponge titanium from a reactor (book "Processing of blocks of sponge titanium", authors: Sandler R.A., Petrunko A.N. and others, published by Metallurgy, Moscow, 1987, p. 70, Fig. 34), selected as the closest analogue. This horizontal press includes front and rear cross members connected by tie rods. The force from the drive, made in the form of a hydraulic cylinder, is transmitted directly to the rod, designed to act on the titanium sponge block located in the retort.

When using this press, a large length of this device is detected due to the size of the rod and the stroke length of the hydraulic cylinder. To reduce the length of the rod, the pushing of the sponge titanium block can occur in two stages. So, a hydraulic cylinder with a large stroke of the rod provides extraction (extrusion) from the retort of the titanium sponge block to the front cross member, and then the rod is extended with a removable tip, and the hydraulic cylinder rod again moves to push the specified block onto the pallet.

Prior to pushing the unit, it is necessary to remove the retort from the installation site. These features reduce the extraction efficiency of the block of sponge titanium.

The problem to which the invention is directed is to increase the efficiency of extracting a sponge titanium block from a retort, to create a compact small-sized device by pushing a sponge titanium block from a retort in several steps, eliminating the blocking of the block on the press elements.

The problem is solved in that the horizontal press for extracting the sponge titanium block from the retort includes a front and rear cross member connected by tie rods, a drive, a bar designed to push the sponge titanium block from the retort, according to the invention is equipped with two traverses, one of these traverses as the movable traverse is connected to the drive and installed with the possibility of forward and reverse motion along the tie rods, as in the guides, between the rear cross member and the second fixed traverse, supporting vayuschey rod, wherein the rod is provided with transverse bores and is mounted to slide freely through the rear cross member, the movable and the fixed crosspiece; on the movable traverse, a gripper is installed for alternately interacting with the corresponding transverse groove of the rod during the forward stroke of the movable traverse, on the stationary traverse, a latch is installed to hold the rod released from the action of gripping during the reverse stroke of the movable traverse.

Some aspects of horizontal press performance:

- the transverse grooves are made circular, the grip is made circular in the form of two drive bolts mounted on the vertical surface of the movable beam, facing the supporting beam, while the bolts are located on both sides of the rod;

- the latch is made in the form of a drive stop for interacting with the surface of the rod and is mounted on a fixed traverse;

- the drive is made in the form of two hydraulic cylinders installed in the rear cross member on two sides relative to the longitudinal axis of the rod, while the hydraulic cylinder rods are mounted on the corresponding surface of the movable beam.

The invention is illustrated as follows.

The presence of two traverses determines the possibility of stepwise movement of the rod and, accordingly, the possibility of pushing the block of spongy titanium from the retort in several stages. One of the traverses, called movable, is connected with the drive and, due to its action, is able to make a direct and reverse stroke along the tie rods between the rear cross member and the second fixed traverse. The tie rods perform the function of guides for the movable traverse. The second fixed beam carries out the function of a means that supports the front end of the rod (the end facing the front cross member), ensures the stability of this rod, helps center the end of the rod to enter the retort pipe.

The implementation of several transverse grooves on the rod and the installation of the gripper to interact with the corresponding groove on the rod provides retention of the rod during the forward stroke of the movable crosshead. In other words, the movable traverse makes a direct stroke with the bar, the limitation of which is the presence of a second fixed traverse.

The presence of a latch on a fixed traverse ensures retention of the rod at the end of the forward stroke. So, the position of the rod, moved together with the movable traverse at the end of the forward stroke, is fixed by appropriate means. At the same time, the movable traverse with the gripper, which freed the bar from its action, makes a reverse stroke. Consequently, the rod moved during the forward stroke of the movable crosshead provides partial ejection of the sponge titanium block from the retort.

The return stroke of the movable traverse is necessary for the resumption of the next next forward stroke, which determines the successive capture of the rod by appropriate means and the subsequent pushing of the sponge titanium block from the retort.

Taking into account the implementation of several transverse grooves, each direct stroke of the traverse moves the bar one step so that the transverse grooves take a new position. At each such step, the corresponding transverse groove takes the place of the previous groove for interaction with the gripper on the movable traverse, which completed the reverse stroke.

The possibility of free sliding of the rod through the rear cross member, movable and fixed crossheads is a necessary condition for stepwise movement of the rod. At the same time, the use of hydraulic cylinders placed on both sides relative to the longitudinal axis of the rod as a drive creates the prerequisites for compact placement of the elements of the inventive press at the production site. So, part of the space of the working platform located behind the rear cross member is used not only for hydraulic cylinders installed in the rear cross member, but also for the location of the rear end of the rod (at the rear cross member), which excludes the placement of the entire rod in front of the rear traverse.

Thus, the new set of features of the device is aimed at reducing the length of the rod due to the possibility of exposure to the block of sponge titanium in several stages, ensuring its gradual expulsion.

For the convenience of gripping the rod and the reliability of movement, it is advisable to carry out transverse grooves circular. Accordingly, the capture can also be made annular in the form of two drive bolts mounted on a movable traverse.

When performing more than two grooves, it is advisable to make grooves with equal pitch. This solution simplifies the process of pushing the block of sponge titanium from the retort during the operation of the press, because the extension of the hydraulic cylinder rods is set to the same value (when performing forward and reverse) and ensures the location of each subsequent groove in place of the previous one, and as a result of several movements, the sponge titanium block is pushed out in equal parts.

To hold the rod during the reverse stroke of the movable yoke, a latch is mounted on the stationary yoke with the possibility of abutment against the surface of the rod.

From the prior art (the book "Forging and pressing equipment of Uralmashzavod", authors: MA Karasev, IV Baranov, FS Blik, VS Soshnikov, Ural PR and advertising center. - "Marat", Yekaterinburg, 2004, 480 s, p. 394, Fig. 11.3.4.) It is known to use a rod (column) with grooves to fix the movable head, which is moved along the bed of a straight-stretching machine (PFP). Given the identity of the PFP elements and the claimed horizontal press, a comparison of the technical results leads to the conclusion that they do not coincide. So, in PFP, fixing the movable head by engaging the rod (column) in the groove provides the PFM adjustment for stretching a workpiece of a certain size with the help of hydraulic cylinders. The presence of grooves on the PPR bar (column) provides interception of the movable head, but such interception is necessary for tuning to a workpiece of a different size. Therefore, the properties of the compared features in the claimed invention and the known tool do not match, because interception of the movable head in the PFP does not reduce the stroke of the plunger of the hydraulic cylinder, because the plunger stroke depends on the maximum length of the product and does not affect the reduction of the longitudinal dimensions of the device (PFP).

In FIG. 1 shows a general view of a horizontal press for extracting a titanium sponge from a retort; in FIG. 2 shows a grip (section AA in FIG. 1); in FIG. 3 shows the latch (section BB in Fig. 1).

The specified horizontal press includes front and rear crossbars 1, 2, connected by tie rods 3, support elements 4, designed to install a retort 5 with block 6 of sponge titanium, a table 7 for unloading block 6 of sponge titanium, located behind the front cross member 1.

Between the rear cross member 2 and the supporting elements 4 there are two traverses: a movable traverse 8 and a fixed traverse 9; the rod 10 is installed with the possibility of free sliding through holes (not shown in the drawings), made in the rear cross member 2, movable and stationary traverse 8, 9.

The movable crosshead 8 from the action of the drive, made in the form of two hydraulic cylinders 11 installed in the rear cross member 2, is installed with the ability to make a direct and reverse stroke along the tie rods 3, performing the function of guides. Hydraulic cylinders 11 are located on both sides of the rod 10, while their rods are mounted on a movable traverse 8.

The rod 10 is made with three annular grooves 12 located with equal pitch. The selected number of grooves 12, the length of the rod and the step between the grooves is determined by the stroke of the rod 10 in one step (in one stroke of the hydraulic cylinders 11), which partially ejects the block 6 of the titanium sponge from the retort 5. The first groove 12 is made at the front end of the rod 10, intended for pushing out the titanium sponge block 6.

To transfer forces from the drive (hydraulic cylinder) 11 to the sponge titanium block 6, an annular gripper 13 is mounted on the movable cross beam 8, made in the form of two crossbars 14 mounted on the vertical surface of the movable cross beam 8 facing the fixed cross beam 9, while the crossbars 14 are located on both sides of the rod 10. The crossbars 14 are driven by pneumatic cylinders 15 (Fig. 2).

FIG. 3 illustrates the latch 16, made in the form of an element (16) with the possibility of abutment from the action of the pneumatic cylinder 17 in the surface of the rod 10. The latch 16 with the pneumatic cylinder 17 is mounted on a fixed crosshead 9.

At the ends of the movable and stationary traverse 8, 9 made thrust elements 18, designed to limit the forward stroke of the movable traverse 8.

The horizontal press operates as follows.

In the initial position of the horizontal press, the hydraulic cylinder rods 11 connected by the movable yoke 8 are maximally retracted, the gripper 13 on the movable yoke interacts with the first annular groove 12, while the front end of the rod 10 passes through the hole in the stationary yoke 9 and is supported in this way, and the rear end bred over the cross member 2; the retort 5 is pressed against the front cross member 1.

When creating pressure in the hydraulic cylinders 11, the movable crosshead 8 makes a direct course before interacting with the thrust elements 18, while the rod 10 slides through the corresponding holes and pushes part of the block 6 of the titanium sponge onto the table 7. The movable crosshead 8 stops, into the rod 10, freed from the grips , rests on the latch 16, preventing its movement.

The movable traverse 8 makes a return stroke, while the second groove 12 occupies the position of the first groove for interaction with the gripper 13. To make the second and final third forward stroke of the movable traverse 8, the pneumatic cylinder 17 retracts the latch 16 from the rod 10.

In the given example, the horizontal press completely pushes the titanium sponge block 6 onto the table 7 in three steps, moving this block from the retort 5 with each direct stroke of the movable crosshead 8.

Removing a sponge titanium block using a horizontal press eliminates the need to shift the block already removed from the movable beam to the table and allows you to push this block directly from the retort in several steps. The above features of the claimed technical solution characterize it as an effective tool with the property of compactness with the possibility of reducing the length of the production site by reducing the longitudinal dimensions of the tool itself.
