The base of the press 1 contains the head, the lower part 2, as well as the vertical elements 3 located between them. The lower part 2 and the vertical elements 3 can be combined in the form of one piece of front 4 and rear 5, each with a window. The frame 4 is aligned with the underside of the head of the press 1 at its rear side. The supports 6 and 7 are arranged perpendicular to the front of the press under the frames 4 and 5, and on the side of their ends, parallel to the supports 6 and 7, there are parts 8 clamping the plate. The upper head of the press and the other elements are interconnected by preliminary strained rods 9, vertically passing through them and located near the corners of the head. The nuts 10 are screwed onto the ends of the iggang 9. Clamping 1e of the movable plate of part 8 is fastened. to frames 4 and 5. The latter, together with the parts 8, limit the space where the movable plate 11 is located, the position of which is vertically adjustable. The device 12 for feeding material can mark the forms of a reel with a strip material 13 and be mounted on a rotating support with a performance brake to stabilize the rotation of the bobish. From the bobbin, material 13 goes to set 14 of moral rolls. Inside the installation, the correct wave; the material passes through the sets of feed rollers spaced from each other, which move it, and between the feed rollers there is a set of opposing rows of regular rolls spaced apart so that the material, as it passes through the installation, straightens . From the installation of the correct rolls, the material enters the device 15, which controls the size of the loop of material. In the device 15, the material is communicated with the shape of a loop in the form of a letter S. Inside the device 15 there are instruments designed to determine the specified maximum and minimum dimensions of the loop. Installing the correct rolls delivers material at a slightly higher speed than the speed at which the material enters the press, so that under normal conditions the loop of material gradually increases until the sensor in the device detects the maximum length of the loop. A signal is generated and the feed rate of the material through the correct rolls is reduced. With the formation of the minimum loop length, the operation of the press and the installation of the correct rolls is stopped. The looping device is connected to the feeding device 16. The latter interrupts the feeding of material during the press stroke when the die is closed, and feeds it again when the die is open. A plate 17 is placed above the strip of material fed into the press, which, in the event of material jamming or stopping the die, is bent down and actuates a switch that interrupts the material and stops the press. The die set located inside the press consists of the upper 18 and lower 19 parts. The lower part is mounted on the die holder 20 resting on the movable plate 11, the position of which is adjustable vertically between the front and rear frames 4, 5 of the press.

The press of the holoique of the press can generate considerable amount of heat, for which the fan 25 with a driving electric motor 26 is installed at the head of the spring, blowing air through the canals provided in the upper part of the press. Air flows into the vent pipe 27. Waste from the punch passes through the cutting device 28, installed, on the side opposite to the feeding device 16, where they are cut into small pieces and take the form facilitated by their further utilization. The entire press operation is controlled from a control panel 29 mounted next to the press and connected to the electrical cabinet 30. In the press head a pair of anti-rotating crankshafts mounted perpendicular to the front of the press are mounted. The crankshafts 31 and 32 of the press respectively carry gears 33 and 34, which engage with each other and provide a synchronous counter-rotation of the crankshafts. The gears 33 and 34 are located in the compartment 35 formed in the head 23 of the press, which is usually closed with a crinkle 36. The gears are filled with holes 37. The air enters the fan 25 through the hole 38 and exits through the window 39 into the chamber 40. In the BepxHcii part chamber 40 is fitted with a heat exchanger 41, through which the oil is passed in order to cool it with air blown into the chamber 40 by a fan. A plurality of horizontal channels 42 are provided in the lower part of the press head 23, which communicate at one end with the lower part of chamber 40 and the other condom with chamber 43. The latter is located vertically in the press head and ends with a window 44 communicating with pipe 27. Channels 42 are limited to horizontal ribs 45, completed} P) 1 for one unit with the head of the press and protruding to the side of the central part of the head in which two bores 46 are made.

The end of the crankshaft 31 carries toriiuz dyke 53. The edge of the disk 53 is located on the back of 54.55 and the second 56 brake pads. Brake; pads 54 and 55 are normally wrung out from disk 53 and pressed against it when pumping tO liquid to them through pipelines 57 and 58.

The brake pads 56 are pressed to the daska 53 by springs and pressed out of it by supplying fluid to them through the pipeline 59. During the normal press stroke, the brake 56 always 15 is peeled off the disc, but with a loss of pressure in the brake system, this block seizes the disc and stops the drive press.

Brake pads 54 and 55 are used when the crankshafts need to be stopped.

 In the worm end adjacent to the brake disc 53, the crankshaft 31 carries a toothed pulley 60. A toothed belt 16 is driven by a toothed belt 61.

The flywheel coupling, the sleeves 53 and the pulley 60 are located in the 25th compartment 62 of the press head, which is closed with a cover 63.

The crankshaft rests on the head 23 of the press through bearings 64 and 65 provided for this purpose in the head. Each of the bearing housings 30 NIKS 64 and 65 contains sleeve liners 66, 67 inserted into it. Bearing housings 64 and 65 are located on both sides of the crankshaft bend connected to the upper end of the connecting rod 68.

On the side of the bearing housing 65 opposite to the connecting rod 68, there is a counterweight 69, the center of gravity of which is located opposite the center of gravity of the knee in the radial direction 40 from the axis of rotation of the crankshaft. To obtain the corresponding dynamic balancing effect at the opposite end of the crankshaft 31 in the gear wheel 33, holes 37 are made, arranged so that the hard side 45 of the gear wheel 33 opposite the hole side generates the necessary balancing force.

The gears 33 and 34 are massive, and the holes in them are made on the side from which the knee of the corresponding crankshaft is located. Thus, each gear wheel contains an eccentric mass on the side of the corresponding crankshaft, opposite the knee of the crankshaft, and on the same side as the opposite 55 whole 69 mounted on the respective crankshafts. In addition, the eccentric mass of the toothed wheel and the mass of the counterweight are located on the protivopoloha1b1X sides of the wheel of the respective crankshaft.

The disk 53 has a relatively large hub 70, tightly mounted on the tapered portion of the crankshaft and clamped by the nut 71.

The end of the crankshaft 31, on the side opposite to the disk 53, is extended to the bearing 72.

Each brake pad 54 and 55 is attached to the press head 23 and includes parts located on both sides of the disk 53. The crankshaft 32 has a design identical to the crankshaft 31, except that instead of the disk 53 and the pulley 60, in compartment 62, it carries a flywheel coupling.

The end end of the plate is connected to the paldem 73, which has a hole inserted in the upper part of the plunger 74, and is held in it by a plate 75 connected to the plunger via a screw 76.

Plungers 74 and 77 are bolted to the slider 78.

The slider 22 is relatively light and moves exclusively by the plungers 74 and 77, which in turn move in the cylinders 79 and 80, respectively, mounted in the die 23 of the press.

The cylinders 79 and 80 have flanges 81 and 82 underneath, through which they rest against the lower part of the press head.

The upper annular web 83 and lower web 84 of the cylinders 79 and 80 serve as a support surface for guiding one of the E31 plungers 74 and 77, while telling them to reciprocate along the axes of the cylinders 79 and 80.

Between the mentioned bridges of annular bridges of each cylinder there is a space 85 filled with grease to collect leaks.

Each bridge 83 and 84 is provided with circumferential hydrostatic pockets 86. These pockets are placed around a corresponding plunger and designed to create hydrostatic supports between the cylinders and the plungers in order to more accurately move the pistons in the cylinders with the least possible friction.

Each pocket is made in the form of a lot cut-out in the inner surface of the corresponding cylinder.

The pockets 86 are interconnected by axial channels 87, made in the respective cylinders, having branches 88 leading to the respective pockets. The axial channels 87 in their upper part are connected between themselves by an annular channel 89, which is made at the top of the corresponding cylinder, and the supply pipe is connected to the corresponding annular channel 89 through openings 90.

To adjust the vertical position of the movable plate to the cylinders 113, fluid is supplied under pressure, the force of which on the rods 112 is sufficient to overcome the total weight of the movable pin 11 along with the plate 20 and the lower part of the die 19. To move the plate in the desired direction, rotate the nuts 110. when adjustment is completed, a liquid is supplied to the cylinders 113, which presses the rods 112 down. On each side of the movable plate there is a V-shaped element 124 (see fig. TO) located vertically. On one side of the press, the element 124 is aligned with the supplementary element 125 secured to the part 8. On the opposite side, the element 126 picks up the adjacent element 124 and, in turn, is caught by itself from the side opposite to the element 124 by the hydraulic plunger 127. The pressure to the hydraulic plunger is supplied through conduit 128. When relieving pressure from plunger 127, the movable plate can move vertically in the press frame, and when fed to the plunger pressure the plate is fixed in the press frame oval position. Setting the correct rolls (see fig. 22) contains feed rolls 129 and spaced rows of regular rolls placed between them 130. Chain 131 npiffloiWT is in motion fed by the rolls and passes through an asterisk 132 mounted on the shaft 133, carrying pulley 134, around which passes the belt 135, going to the pulley 136 of the drive electric motor 137. Between the electric motor -. The teleme 137 and the pulley 136 are a slip clutch 38. The shaft 133 is also peset izhiv 139, connected with the pulley 141 of the pulse generator 142. The strip of material 13 to be processed enters the device along the bent plate 143 into the space 144 bounded by the bent plate 145. The plate is bent 146 guides the strip to the outlet 147 in a pair of double rolls. The length of the loop of material 13, expandable between the curved plates 143 and 145, can be set by a pair of devices 148 and 149, CONTAINING of lamps and photocells, or by contact sensor b {, or by mechanical switches that are directly affected by the loop. The correct rollers impart to the strip {blades 13 a speed slightly higher than the speed at which the strip enters the press, so that the loop 150 gradually lengthens until the light beam in device 149 is interrupted. Thereafter, the feed rate by the installation of the correct rolls decreases, and the loop is again extended to the maximum value. When the light beam from the lamp with the photocell of the device 148 is interrupted due to the shortening of the loop, the press and the setting of the correct rolls are turned off. The installation speed adjustment circuit of the correct rolls comprises a pulse generator, a device 151 connected to a manually adjustable device 152, which is a switch for controlling the length supplied. The pulse setter receives commands from the limit switch 153 driven by the crankshaft. The pulse setter issues an output signal to counter 154, which receives pulses from the pulse generator via circuit 155. Counter 154 can also receive a signal from device 149 via circuit 156. The output signal from counter 154 is supplied digital-to-analogue preo phaser 157, and a signal from this converter is fed to an instrument 158 controlling. clutch speed. App 158 also receives a signal from the tachometer 159 of the clutch connected to the driving motor 137 and the slip clutch 138 via the circuit 160. The output signal from the instrument 158 is transmitted through the circuit 161 to the winding 162, the control clutch, which changes the clutch of the electric motor 137 with the squared 136. During operation of the loop control device, the current supply to the slip sleeve, which is the power unit for setting the correct rolls, is adjusted as shown in FIG. 23. The lineage illustrates the current supply to the clutch, with starting conditions on the left showing where the average clutch current increases in steps, with each step being generated at the time of the signal from the crankshaft end switch to the pulse generator. When the feed rate of the correct rolls in the installation does not exceed the rate at which the material enters the press from the feeding device, the tachometer 159 of the clutch sends signals to the counter 154, so that the current supplied to the clutch produces the same average value. However, when the loop reaches the length at which the light beam from the lamp in device 149 is interrupted / the signal supplied through the circuit 156 to the counter 154, a sharp drop in the current supplied to the clutch is observed, resulting in a natural delay; feeding the strip of material 13 from setting the correct rolls to the loop control device. The feed delay continues until the interrupted beam of light is restored again, after which the standard operating conditions occur and the loop of the material gradually lengthens again until the above-mentioned light beam is interrupted again. The lamp and the photocell of the device 148 do not participate in regulating the supply of current to the coupling, but when the beam of light from the lamp due to the shortening of the loop-material hits, the installation of the correct rolls immediately stops. Both the press and the driving motor are disconnected, and the brake pads, joint gapper 1e, with the brake disc on the crankshaft 31, are actuated. The feeding device 16 comprises an upper roller 163, which is rotationally rotatable. This roller lies on top of the strip 13 of material fed to the press.
