Description

(54) HYDRAULIC PRESS FOR DEPTH EXTRACT

one

The invention relates to the processing of metals by pressure, in particular to hydraulic presses for deep drawing.

According to the main author. St. No. 846308 is known for a hydraulic deep-drawing press containing a string, a carrier table and a traverse movable driven by a main hydraulic cylinder in the form of a drilled body in which a punching holder is mounted with a rotating mechanism in a vertical plane driven by a movable cross bar 1 .

However, this press does not provide a mechanism for removing stamped parts, which reduces its productivity.

The purpose of the invention is to increase the productivity of the press.

This goal is achieved by the fact that the press is provided with a tray to remove the stamped parts, hinged at one end with a frame and having a groove on the side surface, in which a roller fixed by means of a bracket on the movable cross bar is installed with relative mixing.

FIG. 1 shows a press longitudinal section, a general view; in fig. 2 shows section A-A in FIG. 1 (for the lower position of the mobile cross member); in fig. 3 - the same for the intermediate position of the movable

5 traverses; in fig. 4 - the same, mobile traverse at the top, at the end of stamping.

Claims (1)

The press contains a bed 1, a movable yoke 2 driven by the main hydraulic cylinder 3 by means of a plunger 4, connected with a traverse 2 by means of a hinge 5 and mounted in the open cavity of the punch holder 6 installed in the yoke 2 with a rotation mechanism in the vertical plane and with a punch 7 fixed on it, a table 8 with a die 9 fixed on it, return cylinders 10 plungers 11 of which are rigidly connected to the crosshead 2, an inclined tray 12 for feeding workpieces fixed in the upper part of the base 1 hydraulic cylinder 13, the plunger 14 which is attached vytalki20 Vatel 15, the tray 16 for removal of stamped parts, with one end connected to the frame 1 by a hinge 17. In the traverse arm 18 through two fixed roller 19 in contact with a longitudinal groove 20 formed on the side surface of the tray. The mechanism of rotation of the punch holder 6 is made in the form of fixed by means of the hinge 21 on the yoke 2 two shoulders 22 with rollers 23 and 24 on each shoulder mounted with the possibility of interaction, one with a fixed stop 25 fixed on the frame 1, and the other with movably mounted the yoke 2 by means of the spring 26 with the support 27 and with the lock 28 fixed on the yoke 2. The earring 29 with the hinges 30 and 31 connects the lever 22 with the punch holder 6. The press works as follows. In the lower position of the crosspiece 2, the roller 23 runs onto the stop 25, turning the lever 22 on the joint 21, which by means of the hinge 30 rotates the link 29, which in turn, with the help of the hinges 31 and 5, rotates in the vertical plane by the required angle of the punch holder 6 with the punch 7. The pre-stretched 3arotoBKa 32 in the form of a glass with a bottom is fed through tray 12 and is put on the punch bottom up. From the action of the roller 24, the support 27 moves downwardly, compressing the spring 26. After that, the hydraulic cylinder 3 is turned on and the crosshead 2 under the action of the plunger 4 moves upward, as a result of which the roller 23 moves away from the support 25 and the support 27 under the action of the spring 26 mixes the roller 24 until it stops into latch 28. At the same time, the axes of the hinges 21, 30 and 31 are located on the same straight line, and the punch holder 6 with the punch 6 and the workpiece 32 occupy a rigid vertical position. The ejector 15 occupies the lower position, and the tray 16 removal removed from the working area of the press. After this, the punch 7, the billet 32 is pulled through the matrix 9. V. at the beginning of the stretching, the bottom of the billet 32 is pressed against the end of the pusher 15 and until the end of the draw, the pusher 15 rises together with the plunger And, while the working fluid from the cylinder 13 is drained. Next, turn off the hydraulic cylinder 3 and turn on the returnable hydraulic cylinders 10, under the action of the plungers 11 of which the yoke 2 lowers, and the stamped product 33 remains in the matrix 9. In the lower position of the yoke 2 using the hinge 17, the bracket 18 and the roller 19 in contact with the longitudinal groove 20 are installed the removal tray 16 on the vertical axis of the press, after which the cylinder 13 and the part 33 are turned on by means of the plunger 14 and the ejector 15 from the die 9 onto the tray 16 and are removed from the stamping zone:. . To manufacture the next part, the cycle is repeated. The design of the press, which is alternately fitted into the working area by a punch holder with a punch and a tray for removing the stamped parts, allows the press to significantly increase productivity by reducing spins for unloading parts from the working area. The invention of the hydraulic press for deep drawing on the ed. St. No. 846308, characterized in that, in order to increase productivity, it is provided with a tray for removing the stamped parts, hingedly connected to the frame and having a groove on the side surface, in which a roller mounted with the possibility of relative movement is fixed by means of a bracket on a movable cross bar Sources of information taken into account during the examination 1.
