Description

one

The invention relates to the processing of metals by pressure, and more specifically to the design of horizontal hydraulic presses for pressing solid and hollow profiles by direct and inverse methods. Hydraulic presses are known that contain a pressing tool mounted on a frame, a mouthpiece, a piercing system installed on the frame both sides of the press; auxiliary mechanisms for supplying to the axis of the press a billet, press washer and die-pressing matrix; tatka from the product and the tool and transfer parallel to the CSI press 3j.rotovki, press washers and dies (ij

and C2.

The disadvantages of this press, ow-j

the need for large production areas for the installation of all auxiliary mechanisms, as well as increased cycle time due to the large stroke of the mouthpiece.

The purpose of the invention is to reduce the production of 1 area and cycle time ..

This goal is achieved due to the fact that the auxiliary mechanisms are implemented in the form of three

on the one side of the press, parallel to each other, a slider each of which is equipped with a power drive and a knife made in the form of a ring, the axis of which is parallel to the axis of the press and also two pushers installed on both SIDE of the sliders coaxially with the annular knives at the initial laying of the latter.

FIG. 1 shows a horizontal hydraulic pipe-profile press in plan, general view; in fig. 2 is a cross section A-A in FIG. one; in fig. Figures 3-10 show the position of the press mechanisms during the direct pressing method, FIG. 11-14 - the same, with the inverse method of pressing.

The horizontal hydraulic pipe profile press contains a stack consisting of erected columns. us front 1 and rear 2 fixed traverse, and located between them movable traverse 3 and movable. container 4 placed

5 on the base 5. In the front crosspiece 1, a movable tool mouthpiece 7 fixed by the locks 6 is placed, in which the matrix 8 (Fig. 3) 0 is fixed during the direct pressing method and the hollow ram 9 (on the back) (Fig. 11). A pivoting system 10 is installed in the movable cross-section 3, equipped with the reverse pressing method 11, installed in the holder 12 (in the direct method instead of holder 12, press 9 is set). In the movable container 4, a blank (ingot) 13 is placed, with the direct method of pressing the press washer 14, and with a reverse method, the matrix 8. To mechanize the supply of the ingot 13 and perpendicular to the press axis of the ingot 13 with direct and matrix 8 with the opposite methods of pressing on one side of the press on the frame 15, placed on a common base with a press, three sliders 16-18 are installed parallel to each other, each of which is equipped with a power drive and a ring-shaped knife 19 installed in its front part. For mechanization of the transfer parallel to the axis press with The insert 13 and the press washers 14 for the forward and the die 8 for the opposite pressing methods on the same side of the press on both sides of the sliders 16-18 have two pushers 20 and 21, the axis of which coincides with the axis of the ring-shaped knives 19 at the initial position of the latter.

Hydropress works as follows.

The heated ingot 13. with the help of the tilter 22 enters the axis of the pusher 20. All three sliders 16-18 are in the initial (lowest) position. In the direct extrusion method (Figs. 3-10), the mouthpiece 1, with the extruded product, the press residue 23 and the -npedc washer 14 stuck to it, is pushed by the press stamp 5 into the front cross member 1 (Fig. 4). Pusher 20 ingot 13 is set in slider 18 up to the stop in pusher 21, then slider 18 delivers ingot 13 to press axis (Fig. Container 4 advances on ingot 13. and stops with a small clearance from slider 18. Mouthpiece 7 rises forward, with pressure trigger 23 with the press washer 14 are in the knife zone 19 of the slide 18 (Fig. 6). The slide 18 moves back to its original position and separates the press valve 23 with the press washer 14 from the product (Fig. 7). The entire bag is moved using the tappets; 20 and 21 in such a way that the press. Iyb 14 takes place in the ring-shaped knife 19 p a ram 16, and a press chamber 23 in an annular knife 19 of a ram 17. A ram 16 feeds a press washer 14 onto the axis of the press, separating it from the press residue 23 (FIG. 8). Next the press stamp 9 pushes into the container 4 the press washer 14 and leave back (Fig. 9). The slider 16 returns to its original position. Pressing begins, press residue 23 is pushed into the hopper 24 (Fig. 10). In the reverse method of pressing (Fig. 11-14), the sliders 17 and 18 run forward during the course. synchronously, MundJ of pieces 7 with a ram 9 is retracted into the opening of the front cross member 1, the die 8 is in the slider 16 (Fig. 11) The pusher 20 - matrix 8 and the ingot 13 are moved up to the stop in the pusher 21,

f. then sliders 17 and 18 are fed to the axis of the press (Fig. 12). Pressing the stamp 9 forward, the entire bag is pushed into the container 4 (Fig. 13). Mundatuk 7 goes back, the slider returns to its original position.

5 Mouthpiece 7 with the press stamp 9, sno.va moves forward until it stops, the closures 6 are closed, and pressing starts (Fig. 14). at the end of the pressing stroke of the needle 11, embedded in.

0 a movable crossmember 3, press residue 23 is stitched, container 4 makes a turn forward. The needle 11 returns to its original position, with a press residue 23 and, attached to it, the matrix 8 hangs at the end of the needle 11. A movable crossbar 3 moves backward space free. An annular knife 19, chimney 16, movable cross member 3 is fed to the axis of the press.

Q goes back, when ... it pushes the die 8 into the knife 19. By moving back the slide 16, the die 8 separates from the press residue 23 and returns to the axis of the press, the press residue remains on the needle 11.

 The proposed device auxiliary mechanisms of the press can be used as in the creation of new and modernization of existing presses.
