Description

MECHANICAL PRESS

The utility model relates to mechanical engineering, namely to press-forging equipment.

A mechanical press is known, comprising drive deforming sliders located in horizontal guides of the press frame, some of which are connected by a system of levers and hinges, and the other are connected via a cams and rollers to the press electric motor and a matrix placed between deforming sliders (see A. St., I - 626982, B30I / 06, publ. 05.10.78).

The disadvantage of this press is the lack of a mechanism for dropping finished parts.

A mechanical press is also known, which contains drive desizing sliders located in horizontal guides of the press frame, some of which are connected by a system of levers and hinges, and others are connected via a cams and rollers to the press electric drive and a matrix fixed to the bed between deforming sliders (see article on .} I004I49, B 301/06, publ. March 15, 83).

The disadvantage of this press is the lack of a mechanism for dropping finished parts.

To ensure the dumping of finished parts, a mechanical press containing drive deforming sliders located in horizontal guides of the press bed, some of which are connected by a system of levers and hinges, and others are connected to the press electric drive through cams and rollers and the matrix mounted on the bed between the deforming sliders, is equipped with a resetter, connected to the electric drive through additional cams and rollers and a system of pivotally connected levers, the first two deforming sliders are additionally connected between a system of levers and hinges, the bed table is made with an exit window, over which the matrix is fixed; the ejector is made in the form of a rod vertically mounted in the rails of the vertical support rack with the possibility of reciprocating movement and equipped with a puller at the end, while on the rod between the flange stops there is a fork of the ejector lever, the other end of which is rigidly fixed to the horizontal axis mounted in the vertical rack and tough

connected by the other end with a vertical lever, which is pivotally connected via a connecting rod to a beam yoke pivotally mounted on the bed, on the elongated shoulder of which a direct-acting roller is placed, and a reverse-acting roller is placed on the end of the short arm, and the resetter lever fork is made with vertical cheeks of a curved profile.

The mechanical press is presented in the drawings, where:

in Fig. L is a kinematic diagram of a mechanical press;

The mechanical press contains a bed I, in the horizontal guides 2 of which there are opposite directional deforming sliders 3 and 4 and a deforming slider 5 located perpendicular to the sliders 3 and 4. On the bed I in the working area of its table, an exit window is made between the deforming sliders 3, 4 and 5 6, under which is placed the tray (to hell, not shown) of the receiver of finished parts. Matrix 7 is rigidly fixed above the output window b (see Fig. 4,5 and b). The deforming slider 3 is pivotally connected by levers 8.9 and 10 to the connecting rod II, one of which is connected directly to the deforming slider 4, and the other end is connected to the elbow of the crankshaft 12 of the electric drive, which is made of an electric motor 13 connected by a V-belt drive 14 with an intermediate shaft 15 connected through a gear 16 and 17 with a crankshaft 12. A deforming slider 5 through a pivotally connected lever 18, a connecting rod 19 and a slide 20 (see figures 1,2,3,8 and 9), placed in rails and equipped with rollers 21 and 22, interacts accordingly respectively, with cams 23 and 24 mounted on the crankshaft 12.

The ejector of finished parts is as follows. On the bed I of the press, an upright support 24 is installed next to the exit window 6 (see Figs. 2,4,5 and 7), made with two guides 25, in which a rod 26 is installed, equipped with a puller 27 and two flange stops 28, between which placed the plug 29 of the lever 30 of the ejector. The plug 29 is made with vertical cheeks 31 with curved profiles for smooth interaction with flange stops 28 of the boom 26 of the ejector. The other end of the lever 30 of the ejector is rigidly fixed to the horizontal axis 32 mounted in the vertical support column 24 (see figure 7). At the opposite end of the horizontal axis 32, a vertical step 33 is rigidly fixed, which is pivotally connected via a connecting rod 34 (see Figs. 1, 2, 4 and 5) to a rocker arm pivotally mounted on the frame I 35, on the elongated shoulder of which a direct-acting roller 36 is fixed, and at the end of the short arm there is fixed a reverse-action roller 37 interacting with additional cams 38 of direct and 39-reverse action mounted on the crankshaft 12.

Mechanical press operates as follows. The preheated workpiece 40 (see FIGS. 3 and 5) is placed on the table of the bed I in the positioning support elements 41 between the matrix 7 and the slider 5. The motor 13 is turned on, rotation from which through a V-belt drive 14, the intermediate shaft 15, the gear gear 16 and 17 is transmitted to the crankshaft 12. The cam 23, acting on the roller 21 and the levers 18 and 19, actuates the slider 5, moving it to the matrix 7. DporpaiviMa coulisse 23 is constructed so that with the beginning of the movement of the slider 5 begin to move to nothing re fjy friend to a friend the sliders 3 and 4, to which the movement is transmitted from the crankshaft 12 through the common connecting rod II and levers 10, 9 and B. As soon as the slider 5 presses the workpiece 40 to the matrix 7, it stops, and the sliders 3 and 4 continue oncoming movement until the workpiece 40 is pressed against the matrix 7. At the moment when all three sliders 3,4 and 5 workpiece 40 to the matrix 7, the workpiece is deformed and the finished product is formed. After the pressing process is completed, the slider 5 first returns to its original position due to the interaction of the cam 24 and the roller 22, which, through the pivotally connected levers 18 and 19, move the slider 5 from the matrix 7. Then the sliders 3 and 4 diverge in opposite directions. And only after that the cam 38 reset, interacting with the roller 36, actuates

Matrix 7 is freed for a new operation. After that, the reverse cam 39 interacts with the roller 37, and the whole system of articulated levers 35,34,33 and 31 moves in the opposite direction, returning the rod 26 to its original position. Next, the cycle repeats.
